DEAR SHAREHOLDERS,                                                  JUNE 8, 2007
- --------------------------------------------------------------------------------

      In our October 31, 2006 report, we likened the new global economy to a
"Brave New World." While we are usually loath to recycle a metaphor so quickly,
in this case, it seems fitting to continue to use it. Nothing that has happened
over the past six months alters our view that we are entering uncharted waters
for both the global economy and for the thousands of companies that are being
reshaped by it.

      As with any sweeping change, there are those who embrace it and try to
anticipate the risks and rewards; there are those who deny that there is any
change; and finally those who simply wait to see what everyone else thinks. At
Alger, we fall into the first camp, and, in fact, believe that we are still in
the early stages of a radical shift in how the global economy functions; one
that has already produced new winners and losers, not just in terms of nations,
but of companies that are seizing the opportunities and those that are unable
to. While the story of China and India is familiar, it is hardly limited to them
and now includes such disparate regions as Vietnam, Eastern Europe and
Australia, to name three, all of which are adding additional complexity and
additional fuel to the expanding global economy.

      Here then is our six-month postcard from this Brave New World. The themes
include the greening of corporate America and the lessons gleaned from the swift
fall and startling sharp recovery of the equity markets on February 27. They
include the coming of age of private equity as a force that can move and shape
the markets, and the importance of free cash flow as a metric for measuring the
strength of corporate balance sheets. And of course, one other theme stands out
above all -- the surprising (at least to most on Wall Street) strength of
corporate earnings at the end of the first quarter.

THE CONVERGENCE OF BUSINESS AND GREEN

      The beginning of 2007 saw one of the warmest Januaries on record, but
instead of snow, we were treated to a flurry of articles, announcements,
conferences, and high level public speeches that demanded action on the part of
countries, individuals and companies to address the issue of global warming.
Appearing simultaneously but independently, FORTUNE, THE ECONOMIST and
BUSINESSWEEK all ran lengthy cover stories describing the shift in corporate
America to embrace socially responsible business practices as a better -- and
potentially more profitable -- way of doing business. These articles were the
most noticeable in a few weeks' span, but they were hardly a comprehensive list
of the hundreds published about the greening of corporate America, not to
mention Europe, Asia, and the world. By late January, whether or not "greening"
was a mere zeitgeist was debatable. But on February 2, the Intergovernmental
Panel on Climate Change issued their Fourth Assessment Report indicating that
global warming was "unequivocal" -- a real and growing danger.

      In response, many dynamic, innovative companies are stepping up and
looking for ways to solve the intractable issues of energy and the environment.
Case in point is private equity firms Kohlberg Kravis Roberts and Texas Pacific
Group, which

                                                                             -1-



announced plans to acquire one of the largest public utility companies in the
United States, TXU. What made the TXU deal distinctive were the conditions
attached to its approval. Under the proposed terms, KKR and Texas Pacific agreed
to several substantial concessions to environmental groups including scaling
back plans to build new coal-fired power plants while aggressively working on
so-called "clean coal" technologies (i.e. coal gasification) that lower and
potentially eliminate emissions. They also agreed to increase R&D spending on
alternate energy by as much as half a billion dollars. Goldman Sachs, who
brokered the deal, pressured both sides to agree to the pro-environment change
in the initial plans. The result was a deal hailed by Wall Street and the green
lobby in equal measure.

      The convergence of vast amounts of private equity cash and
environmentalism was a sign of the cultural, global shift taking place. Clearly,
a number of the major investment banks already saw the long-term value in their
companies "going green," and the rest of the financial world was swiftly joining
them.

THE RETURN OF VOLATILITY

      On February 27 global stock markets saw their most dramatic sell-off in
years. Wall Street pundits were, as usual, divided. Some said it was a
long-awaited correction and a sign of a weakening economy, while others said it
was simply the return of volatility to what has been a fairly stable market.

      That said, nothing actually happened to trigger the declines. No sudden
change in the economic forecasts. No critically bad economic or corporate news.
However, there were rumors in Shanghai and Beijing that a government squeeze on
credit and stock-speculation was imminent, and that alone was enough to send
investors fleeing. But even after the sell-off, the Shenzhen market --
Shanghai's smaller sibling -- was still up more than 30% year-to-date, and well
over 100% for the past 12 months. Hardly comforting if you bought on Monday
before the sell-off, but not bad for those who had been in those markets for
more than a couple of months.

      What happened? In our view this was a market phenomenon, a brief reminder
of volatility after months of stability, and a bout of profit-taking and
stepping aside that had been long overdue. Within days, fears of a "global bear
market" dissipated as continued liquidity and private equity activity bolstered
markets both in the United States and around the world.

PRIVATE EQUITY AND FREE CASH FLOW

      For the first half of the fiscal year, private equity activity was truly
impressive, with the purchase of troubled companies such as Chrysler that in
earlier years would have made unlikely buyout targets. While no major company
today -- public or private -- seems beyond private equity interests, there is
one theme that unites both private equity and mutual fund investors: free cash
flow.

      At Alger, as bottom-up, fundamental investors, one of the key metrics we
use is the ability of companies to generate free cash flow. Why? Because free
cash flow can fund further growth at a company, pay dividends, and allow for the
buy-back of stock in order to return value to shareholders -- all of which,
properly done, can contribute to earnings growth and shareholder value. It is a
sign of both a strong busi-

                                                                             -2-



ness model and disciplined financial management to be able to grow (at
impressive rates) and not require constant infusions of new capital. We think
that private equity firms buying public companies of all sizes and across many
industries is not irrational. It is seizing an opportunity to acquire solid
franchises that are generating strong cash flows at extraordinary valuations for
the long-term investor. And the amount of private equity activity is another
confirmation that globalization, broadly speaking, benefits U.S. corporate
profits.

THE EARNINGS SURPRISE

      At the beginning of 2007, the overwhelming consensus was that after
several years of strong, double-digit earnings growth, the first quarter would
show the companies of the Standard & Poor's 500(i) slowing to an anemic 3-4%
growth rate. That assumption was based on several factors including the woes of
the U.S. housing market, the slowing of the U.S. industrial economy, and the
basic assumption that corporate earnings would have to "revert to the mean" of
their multi-decade average (about 7%) and hence dip significantly. All of these
assumptions proved to be wrong.

      When all was said and done at the end of reporting seasons for the first
quarter of 2007, the S&P companies registered earnings growth of about 9%, and
nearly three-quarters of all companies have reported positive "surprises"
relative to expectations. Indeed, at the tail end of May, the S&P broke its own
record, reaching heights last seen seven years ago during the heady days of the
technology boom -- and this despite another minor overnight sell-off in China.
So what happened? It's a case of our friends back at the Old World struggling to
explain New World geography in terms they're familiar with -- even if those
terms don't quite fit anymore.

      True, most top-down analysts were correct about their predictions of the
slowdown of the U.S. economy. In fact, first quarter GDP growth was even worse
than had been predicted, registering a paltry 0.6% growth on weak exports and
slower corporate capital expenditures. But the experts also continued to use the
United States and past economic patterns as a proxy for predicting earnings for
U.S.-listed companies. This made perfect sense for the last half of the 20th
century, when the United States was the dominant economic power globally and
U.S. corporations reflected that strength. But while the United States remains
far and away the largest economy, it is simply no longer the sole engine of
growth or the fastest. As such, the U.S. economy and economic data are no longer
a good proxy for how companies will do. Instead, they may well mislead investors
and analysts to underestimate the growth of U.S.-listed companies.

      We have said for the past three years -- for most of this decade, in fact
- -- that the U.S. markets have been good markets for "stock pickers" in that they
have not been either notably frothy or notably flighty (occasional junctures
notwithstanding). What is now emerging, we believe, is a global "stock picker"
market, but many people are still playing markets rather than stocks. That
leaves some markets and many stocks, especially U.S.-listed ones and U.S.-listed
growth equities above all, undervalued and less loved than they should be. And
that, of course, represents an opportunity to pick and choose quality growth
companies while the rest of the investing community focuses their eyes
elsewhere.

                                                                             -3-

IN SUMMARY

      Six months ago, we surmised that braving the waters of the new global
economy would provide both challenges and opportunities. Indeed, the first half
of the year bore this out and often rewarded the innovative, dynamic companies
and investors that embraced those changes. Going forward, we expect more of the
same as the global, economic landscape continues to expand and evolve. As the
first six months of this fiscal year come to a close, we would like to thank you
for continuing to journey with us and entrusting us with your investing needs.

A WORD ABOUT RISK

      Growth stocks tend to be more volatile than other stocks as the price of
growth stocks tends to be higher in relation to their companies' earnings and
may be more sensitive to market, political and economic developments. Investing
in the stock market involves gains and losses and may not be suitable for all
investors. Stocks of small- and mid-sized companies are subject to greater risk
than stocks of larger, more established companies owing to such factors as
limited liquidity, inexperienced management, and limited financial resources.
Funds that participate in leveraging, such as the SmallCap and MidCap
Institutional Funds, are subject to the risk that borrowing money to leverage
will exceed the returns for securities purchased or that the securities
purchased may actually go down in value; thus, the Fund's net asset value can
decrease more quickly than if the Fund had not borrowed. For a more detailed
discussion of the risks associated with a Fund, please see the Funds'
Prospectus.

      MUTUAL FUNDS ARE NOT INSURED BY THE FDIC, ARE NOT DEPOSITS OR OTHER
OBLIGATIONS OF, OR GUARANTEED BY BANKS, AND ARE SUBJECT TO INVESTMENT RISKS,
INCLUDING POSSIBLE LOSS OF PRINCIPAL AMOUNT INVESTED.

      BEFORE INVESTING, CAREFULLY CONSIDER THE FUND'S INVESTMENT OBJECTIVE,
RISKS AND CHARGES AND EXPENSES. THE FUNDS' PROSPECTUS CONTAINS THIS AND OTHER
INFORMATION ABOUT THE FUNDS, AND MAY BE OBTAINED BY ASKING YOUR FINANCIAL
ADVISOR, CALLING US AT (800) 992-3863, OR VISITING OUR WEBSITE AT WWW.ALGER.COM,

BEFORE INVESTING.

Fund, MidCap Growth Fund and Capital Appreciation Fund (collectively, the
"Funds" or individually, each a "Fund"). The LargeCap Growth Fund, SmallCap
Growth Fund, MidCap Growth Fund and Capital Appreciation Fund normally invest
primarily in equity securities and each has an investment objective of long-term
capital appreciation.

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). Securities for which such information is
readily available are valued at the last reported sales price or 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 reported sales,
securities are valued at a price within 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 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. Developments that occur between the close of the 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 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.

In September 2006, the Financial Accounting Standards Board (FASB) issued
STATEMENT ON FINANCIAL ACCOUNTING STANDARDS NO. 157, "FAIR VALUE MEASUREMENTS"
(FAS 157). This standard clarifies the definition of fair value for financial
reporting, establishes a framework for measuring fair value and requires
additional disclosures about the use of fair value measurements. FAS 157 is
effective for financial statements issued for fiscal years beginning after
November 15, 2007 and interim periods within those

                                                                            -42-



- --------------------------------------------------------------------------------
THE ALGER INSTITUTIONAL FUNDS |
NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

fiscal years. As of April 30, 2007 the Funds do not believe the adoption of FAS
157 will impact the amounts reported in the financial statements, however,
additional disclosures will be required about the inputs used to develop the
measurements of fair value and the effect of certain of the measurements
reported in the statement of operations for a fiscal period.

(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 may enter into repurchase agreements with
institutions approved by the Board of Trustees. The repurchase agreements are
collateralized by U.S. Government and agency 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
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. There were no securities on loan during the six months
ended April 30, 2007.

(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

                                                                            -43-



- --------------------------------------------------------------------------------
THE ALGER INSTITUTIONAL FUNDS |
NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

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.

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN
48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Funds' tax returns to determine whether the tax positions are
"more-likely-than-not" of being sustained by the applicable tax authority. Tax
positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is
required for fiscal years beginning after December 15, 2006 and is to be applied
to all open tax years as of the effective date. At this time, management is
evaluating the implications of FIN 48 and its impact in the financial statements
has not yet been determined.

(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.

(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.

                                                                            -44-

Growth Fund and the Capital Appreciation Fund incurred fees of $118, $49,208,
$3,119 and $373 respectively, for these services provided by Alger Services.

(E) OTHER TRANSACTIONS WITH AFFILIATES: Certain trustees and officers of the
Trust are directors and officers of Alger Management, the Distributor and Alger

of Trustees receives an additional annual fee of $10,000 which is paid, pro
rata, by all funds managed by Alger Management. Additionally, each member of the

The differences between book basis and tax basis unrealized appreciation is
determined annually and is attributable primarily to the tax deferral of losses
on wash sales.

At October 31, 2006, the Funds, for federal income tax purposes, had capital
loss carryforwards which expire as set forth in the table below. These amounts
may be applied against future net realized gains until the earlier of their
utilization or expiration.

NOTE 8 -- LITIGATION:
- --------------------------------------------------------------------------------

Alger Management has responded to inquiries, document requests and/or subpoenas
from various regulatory authorities, in connection with their investigations of
practices in the mutual fund industry identified as "market timing" and "late
trading." On October 11, 2006, Alger Management, Alger Inc. and Alger
Shareholder Services, Inc. executed an Assurance of Discontinuance with the
Office of the New York State Attorney General ("NYAG"). On January 18, 2007 the
Securities and Exchange Commission issued an order implementing settlements
reached with Alger Management and Alger Inc. As part of the settlements with the
Commission and the NYAG, without admitting or denying liability, the firms paid
$30 million to reimburse fund shareholders and a fine of $10 million; and agreed
to 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
Funds that the settlement has not adversely affected the operations of Alger
Management, Alger Inc. or their affiliates, or adversely affected their ability
to continue to provide services to the Funds.

On August 31, 2005, the West Virginia Securities Commissioner (the "WVSC") 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 (the "WVUSA"), and ordered Alger Management and Alger
Inc. to cease and desist from further violations of the WVUSA 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 WVSC. 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 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

                                                                            -51-

THE ALGER INSTITUTIONAL FUNDS |
NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

similar allegations was filed by the West Virginia Attorney General and also
transferred to the Maryland District Court, but such lawsuit has since been
withdrawn.

The Derivative Complaint alleged (i) violations, by Alger Management and,
depending on the specific offense alleged, by Alger Inc. and/or the fund trustee
defendants, of Sections 36(a), 36(b), 47, and 48 of the Investment Company Act
of 1940, as amended, (the "Investment Company Act") and of Sections 206 and 215
of the Investment Advisers Act of 1940, as amended, 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,
including the Funds, and the current and former fund trustees and officers, of
Sections 11, 12(a)(2), and 15 of the Securities Act of 1933, as amended,
Sections 10(b) (and Rule 10b-5 thereunder) and 20(a) of the Securities Exchange
Act of 1934, as amended, (the "1934 Act"), and Section 34(b) of the Investment
Company Act, (ii) breach of contract by the funds named as defendants, and (iii)
unjust enrichment of the defendants.

Motions to dismiss the Class Action Complaint and the Derivative Complaint were
subsequently filed.

As a result of a series of court orders, all claims in the Class Action
Complaint and the Derivative Complaint have been dismissed, other than claims
under the 1934 Act against Alger Management, Alger Inc., Alger Associates, Inc.
and Alger Shareholder Services, Inc., and certain present and former members of
the senior management of Alger Management and/or Alger Inc., and claims under
Section 36(b) of the Investment Company Act against Alger Management, Alger
Inc., Alger Associates, Inc. and Alger Shareholder Services, Inc.

                                                                            -52-

ADDITIONAL INFORMATION (UNAUDITED)
- --------------------------------------------------------------------------------

SHAREHOLDER EXPENSE EXAMPLE
- --------------------------------------------------------------------------------
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, 2006 and ending April 30, 2007.

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.

                                                                            -53-
