APRIL 2004

DEAR SHAREHOLDER:

Writing a report for the Marsico Funds that encompasses the six months ending
March 31, 2004 presents the challenge of reviewing investment results in a
reasonable number of pages. To present a helpful summary for you, we thought it
would be appropriate to start with a review of each Fund's performance for the
six-month period ending March 31, 2004. This section is meant to provide a brief
retrospective for the past six months, and to explain the main reasons for the
Funds' investment results - while simultaneously trying to avoid repetition of
prior shareholder correspondence. Then we shift gears and offer a few comments
regarding the Funds' current investment posture. For a detailed discussion of
our economic and market outlook, we would refer you to the most recent quarterly
shareholder letter, mailed to you a few weeks ago.

INVESTMENT REVIEW BY TOM MARSICO

MARSICO FOCUS FUND AND MARSICO GROWTH FUND

The Focus Fund and Growth Fund posted total returns of 11.34% and 12.49%,
respectively, for the six months ending March 31, 2004.(1) For comparative
purposes, the S&P 500/R Index - which we consider to be the Fund's primary
equity benchmark - had a total return of 14.08% over the same period of time.(1)
The Funds reached 61/4 years of operating history as of the end of March 2004.
Please see the Fund overviews for more information regarding the Funds' longer-
term investment results. The performance data quoted here represents past
performance, and past performance is not a guarantee of future results.
Investment return and principal value of an investment will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than their original
cost. Current performance may be lower or higher than the performance
information quoted. To obtain performance information current to the most recent
month-end, please call 888-860-8686 or visit www.marsicofunds.com.

The Focus Fund and Growth Fund may often invest in similar growth companies.
Still, their performance may differ at times because the Focus Fund invests in a
relatively more concentrated portfolio of securities, while the Growth Fund may
hold some positions not present in the Focus Fund.

The six-month period encompassed in this report was a "bull market" for US
large-capitalization companies, as represented by the S&P 500/R Index, as
investors seemed cheered by signs of an improved economic environment, continued
fiscal and monetary stimulus, and encouraging corporate profit reports. The
period was characterized by a broad-based rally for equities, with the vast
majority of sectors and industries having strong gains. All 10 economic sectors
that comprise the S&P 500/R Index had a positive return for the period from
October 1, 2003 through March 31, 2004. Eight of the ten sectors had returns in
excess of 10%. Energy (+21%), Materials (+21%), Telecommunications Services
(+19%), Financials (+17%), and Consumer Discretionary (+16%) were the market
leaders. Health Care, with a gain of 7%, was the weakest performing economic
sector, while Information Technology posted a return of 10%.

- --------------------------------------------------------------------------------



- --------------------------------------------------------------------------------

As a further testament to the overall strength of the equity markets, we note
that 13 industry groups (out of 20 in the S&P 500/R Index) had gains of 15% or
higher, while five industries experienced returns of 20% or more, including:

o  Hotels/Restaurants/Leisure                       27%
o  Consumer Durables and Apparel                    26%
o  Insurance                                        21%
o  Communications Services and Supplies             21%
o  Automobiles and Components                       21%

Although the Funds generated relatively strong absolute results over the past
six months, their overall returns did not quite keep up with the performance of
the S&P 500/R Index. To a significant extent, that "shortfall" could be
attributed to the Funds' middling performance in the fourth quarter of 2003.
Investment results for the Growth Fund were stronger than the S&P 500/R Index
during the first quarter of 2004, while the Focus Fund slightly underperformed
the Index.

There were several areas of strength for the Funds during the past six months.
These included:
o  Health Care Investments-The Funds' aggregate holdings in this sector gained
   more than 20% over the six-month period, substantially outpacing the
   sector's return (8%) within the S&P 500/R Index. Service provider
   UnitedHealth Group (28%), medical device company Boston Scientific (33%),
   and biotechnology company Genentech (32%) were among both Funds' best-
   performing holdings. In addition, the Growth Fund benefited from investments
   in medical testing and device companies Quest Diagnostics (37%) and Zimmer
   Holdings (34%). (The Focus Fund did not own Zimmer Holdings during the six-
   month period, and sold its position in Quest Diagnostics prior to a
   significant rally in the stock.)(2)

- --------------------------------------------------------------------------------



- --------------------------------------------------------------------------------

o  Information Technology-The Funds' investment returns benefited on several
   levels within this sector. Both Funds maintained an underweighted posture
   (as compared to the S&P 500/R Index) in the Software and Services industry,
   which was the weakest-performing industry in the Index over the six-month
   period. QUALCOMM, a company emphasizing wireless technology, was one of the
   Funds' larger individual holdings, and gained 60% over the six-month period.
   That return helped buoy overall Fund performance by a material degree.(2)

o  Homebuilding-related-Both Funds benefited from investments in the
   homebuilding industry. The Growth Fund on average had a larger allocation
   (including MDC Corporation and Lennar Corp. (Class A)) to this industry than
   the Focus Fund, which was one of the primary reasons why it outperformed the
   Focus Fund during the six-month period.(2)

The Funds' limited underperformance compared to the S&P 500/R Index could be
ascribed primarily to the Funds' not having investments in certain economic
sectors such as Energy, Materials, and Insurance, which performed well over the
six-month period. (As noted earlier, these sectors/industries were among the
strongest areas of the stock market over the six-month period covered in this
report.) Additionally, the Funds were negatively impacted by the following
factors:

o  Retailing Investments-The retailing industry, as represented by the S&P
   500/R Index, had a return of more than 16% for the six months ending March
   31, 2004. The Funds' retailing investments, in aggregate, experienced a
   modest decline over that period of time. The primary "culprits" for us were
   Tiffany & Co. (3% return) and Amazon (-14% decline in the Focus Fund, and a
   -12% decline in the Growth Fund prior to being sold).(2)

- --------------------------------------------------------------------------------



- --------------------------------------------------------------------------------

o  Diversified Financials-Similar to the retailing industry, this area was one
   of the better-performing industries (+17%) for the S&P 500/R Index. Although
   the Funds' Diversified Financials holdings produced positive returns in the
   aggregate, they lagged the industry's return in the benchmark by a
   considerable degree. This was primarily attributable to the Funds' positions
   in SLM Corporation, which had a return of just 8%. SLM was one of the Funds'
   largest holdings, which exacerbated its relative performance impact.(2)

o  Industrials-Capital Goods and Transportation holdings adversely impacted
   Fund performance. In the Capital Goods industry, the Funds had a significant
   weighting on average in General Electric, whose 4% return, although
   positive, substantially trailed the performance of the S&P 500/R Index.
   Meanwhile, certain Airline positions (e.g., RyanAir Holdings in the Focus
   Fund and JetBlue Airways in the Growth Fund) had significant negative
   returns during the period in which they were owned in the Funds. RyanAir
   Holdings sustained a -18% decline prior to being sold, while JetBlue Airways
   fell by -36% before it, too, was sold.(2)

o  Media-Comcast Corporation, which declined by -13% during the time
   it was owned in both Funds, had a materially negative impact on investment
   results.(2)

As of March 31, 2004, the Funds' primary sector allocations were in Consumer
Discretionary, Health Care, Industrials, and Financials. During the previous six
months, the Funds' positions in Information Technology companies were reduced
(e.g., positions in companies such as Intel and Cisco Systems were sold), while
investments were increased in areas such as Health Care, Financials, Consumer
Staples, and Industrials. As of March 31, the Funds had little or no exposure in
areas such as Energy, Utilities, and Telecommunications Services.(2)

- --------------------------------------------------------------------------------



- --------------------------------------------------------------------------------

I want to take a moment to acknowledge the contributions of Jim Hillary, who co-
managed the Focus and Growth Funds with me during this period, and his departure
from our Company on April 30, 2004. We are sorry to see Jim leave. Jim was one
of the original partners when we created Marsico Capital Management in 1997.
Over the past 61/2 years, he made numerous contributions to the firm, our
investment process, and our Fund performance. He and I worked closely together
over that entire period of time. All of us will miss Jim, professionally and
personally, and we wish him well with his future endeavors.

Thank you for being an investor in the Fund.
Sincerely,

/s/ Thomas F. Marsico

INVESTMENT REVIEW BY CORY GILCHRIST

MARSICO 21ST CENTURY FUND

The 21st Century Fund had a total return of 17.39% for the six-month period
ending March 31, 2004.(1) For comparative purposes, the S&P 500/R Index (which
we consider to be the Fund's primary benchmark), Nasdaq Composite Index, and
Wilshire 5000 Index had total returns of 14.08%, 11.90%, and 15.36%,
respectively, over the same period. (The Wilshire 5000 Index is designed to
reflect investment results for the overall US stock market, spanning both large-
and smaller-capitalization companies.)(1) Please see the Fund overviews for more
information regarding the Fund's longer-term investment results. As noted above,
the performance data quoted here represents past performance, and past
performance is not a guarantee of future results. Investment return and
principal value of an investment will fluctuate so that an investor's shares,
when redeemed, may be worth more or less than their original cost. Current
performance may be lower or higher than the performance information quoted. To
obtain performance information current to the most recent month-end, please call
888-860-8686 or visit www.marsicofunds.com.

Over the six-month period covered in this report, several factors influenced the
21st Century Fund's investment results. The most prolific positive factor was
the Fund's investments in the Consumer Discretionary sector. This was a
significant area of emphasis for the Fund throughout the past six months; as of
March 31, 2004, approximately 38% of the Fund's net assets consisted of Consumer
Discretionary holdings. The Fund's total holdings in this sector gained 26%
during the past six months. The Fund benefited in part from being relatively
overweighted in the sector (as compared to its benchmark indexes), while
industry positioning and stock selection also added value. In particular,
investments in two industries were strong performers:

o  Consumer Durables-The Fund's investments in this industry appreciated in
   aggregate by nearly 55% during the six-month period. These included
   homebuilding-related companies (e.g., WCI Communities, which gained 52%) and
   Harman International Industries, a manufacturer of high-fidelity audio
   products and electronic systems, which had a 61% gain in its
   stock price.(2)

- --------------------------------------------------------------------------------



- --------------------------------------------------------------------------------

o  Hotels/Leisure-The Fund (as compared to its benchmark index) had an
   overweighted posture in this industry, which helped investment results. And,
   we were fortunate to have success with several related holdings, including
   hotel/casino operators Wynn Resorts (93%) and Mandalay Resort Group
   (13%).(2)

The Fund's performance was materially impacted, in a positive manner, by
positions owned in the Health Care sector as well as certain holdings in the
Financials sector. In Health Care, the Fund's positions collectively had a
return of 38% during the past six months. More specifically, strong returns were
achieved in equipment/services companies (e.g., UnitedHealth Group, 28%) and
biotechnology (e.g., Genentech, 32%, and Kinetic Concepts, 50%).  Kinetic
Concepts was an Initial Public Offering. Within the Financials sector, banking-
related holdings had strong relative returns, including UCBH Holdings (33%), a
San Francisco-based company focused on providing local banking services for
Asian-Americans and others, and Countrywide Financial Credit (15%), a
residential mortgage banking and service company.(2)

A significant "weak link" performance-wise for the Fund was the Industrials
sector, particularly our holdings in the Transportation industry. We sold all of
our Transportation holdings prior to March 31, 2004, but not before sustaining,
in aggregate, a -13% loss on these investments during the six-month period. In
particular, JetBlue Airways (-36% prior to being sold) and RyanAir Holdings
(-12%) negatively impacted performance. Certain retailing holdings also were
relatively weak performers for us. These included Electronic Boutique (-17%
prior to being sold), a video game hardware and software retailer, PetSmart
(-12% prior to being sold), and Select Comfort (4%), a manufacturer of
adjustable-firmness mattresses.(2)

- --------------------------------------------------------------------------------



- --------------------------------------------------------------------------------

As of March 31, 2004, the Fund maintained three primary areas of emphasis in
terms of economic sector distribution. These included Consumer Discretionary
(38% of net assets), Financials (31%), and Health Care (12%). During the past
six months, the Fund reduced its allocation to Technology and Industrial
companies. As of March 31, the Fund did not have any significant exposure to
sectors such as Utilities, Telecommunications Services, and Energy.

Thank you for your support.

Sincerely,

INVESTMENT REVIEW BY JIM GENDELMAN

MARSICO INTERNATIONAL OPPORTUNITIES FUND

The International Opportunities Fund had a (US$) return of 26.28% for the six-
month period ending March 31, 2004.(1) For comparative purposes, the Morgan
Stanley Capital International EAFE Index, which we consider the Fund's primary
international benchmark, had a total (US$) return of 22.16% for the same
period.(1) Please see the Fund overviews for more information regarding the
Fund's longer-term investment results. As noted above, the performance data
quoted here represents past performance, and past performance is not a guarantee
of future results. Investment return and principal value of an investment will
fluctuate so that an investor's shares, when redeemed, may be worth more or less
than their original cost. Current performance may be lower or higher than the
performance information quoted. To obtain performance information current to the
most recent month-end, please call 888-860-8686 or visit www.marsicofunds.com.

Investment results over the past six months were driven primarily by the
following factors:

o  Consumer Discretionary-For the six-month period ending March 31, 2004, this
   sector was the most significant contributor to the Fund's outperformance as
   compared to the Fund's benchmark index. Collectively, the Fund's holdings
   had an aggregate total return of nearly 32% for this period. Media
   positions, which rose 47%, were particularly strong investments. The Fund's
   media holdings included EMI Group, Sogecable (a Spanish media company), and
   NTL (a United Kingdom-based broadband communications and services company).
   Another individual holding that performed well for the Fund was hotel/casino
   operator Wynn Resorts, which rose by nearly 93%. Retailing companies Esprit
   Holdings (43%), located in Hong Kong, and Yamada Denki (33%), based in
   Japan, also contributed materially to the Fund's results. Sharp Corporation,
   a South Korean manufacturer of flat-panel display televisions, gained 23%
   during the time it was owned in the Fund.(2)

- --------------------------------------------------------------------------------



- --------------------------------------------------------------------------------

o  Financial Services-This sector overall was an important contributor to the
   Fund's performance, led primarily by the Fund's banking positions, which
   gained 34% collectively. Specific positions owned in this sector included
   certain Japanese banks (Mitsubishi Financial and UFJ Holdings). Other
   banking positions that performed well were Erste Bank der Oster (Austria-
   based), OTP Bank (Hungary-based), ICICI Bank (India-based), and Unibanco-
   Unaio de Brazil.(2)

o  Telecommunications Services-The Fund's investments in this sector gained 83%
   in the aggregate for the period in which they were owned during the past six
   months. Russia-based Mobile Telesystems, the Fund's sole "pure"
   Telecommunications holding as of March 31, gained 79% for the period in
   which it was owned during the past six months.(2)

o  Select Technology Investments-Investments in industries such as
   Semiconductors and Semiconductor Equipment (e.g., Samsung Electronics and
   ASM Pacific Technology) and hardware and equipment (e.g., AU Optronics,
   Canon, and Keyence) performed well for the Fund. SAP, a Germany-domiciled
   software company, gained 29%.(2)

The main areas that detracted from the Fund's performance as compared to its
benchmark index were industries such as Transportation (e.g., regional airline
RyanAir Holdings), Automobiles (e.g., Nissan Motor, BMW), and certain
Technology-related holdings (e.g., Yahoo! Japan Corporation, Sohu Com, and
Nortel Networks).(2)

Neither country allocations nor currency had a material impact in the aggregate
on the Fund's performance. Generally, the Fund's country allocations are a
residual factor in our investment process; we are typically more focused on
sectors, industries, and individual companies in formulating our investment
strategy. In a related vein, currency-related strategies are not a central facet
of the Fund's investment process.

- --------------------------------------------------------------------------------



- --------------------------------------------------------------------------------

As of March 31, 2004, the Fund's holdings in terms of economic sector
distribution were allocated primarily to Consumer Discretionary, Financials, and
Information Technology. The Fund's largest country allocations were in Japan,
United Kingdom, Switzerland, and South Korea.

Thank you for including the International Opportunities Fund as part of your
investment program.

Sincerely,

The performance data quoted here represents past performance, and past
performance is not a guarantee of future results. Investment return and
principal value of an investment will fluctuate so that an investor's shares,
when redeemed, may be worth more or less than their original cost. Current
performance may be lower or higher than the performance information quoted. To
obtain performance information current to the most recent month-end, please call
888-860-8686 or visit www.marsicofunds.com.

     The performance included in the table and graph do not reflect the
     deduction of taxes on Fund distributions or the redemption of Fund shares.
(1)  The performance returns for the International Opportunities Fund reflect a
     fee waiver in effect; in the absence of such a waiver, the returns would
     have been 62.88% for the one year period ended 3/31/04, 2.85% since
     inception through 3/31/04, and the ending value of a $10,000 investment
     would have been $11,113 on 3/31/04.
(2)  This chart assumes an initial investment of $10,000 made on June 30, 2000
     (inception).
(3)  Sector weightings represent the percentage of the Fund's equity investments
     in certain general sectors. These sectors may include more than one
     industry. The Fund's portfolio composition is subject to change at any
     time.
     The Morgan Stanley Capital International EAFE Index tracks the stocks of
     about 1,000 companies in Europe, Australasia, and the Far East (EAFE). You

NOTES TO FINANCIAL STATEMENTS

MARSICO FUNDS
MARCH 31, 2004 (Unaudited)

1.   ORGANIZATION
     The Marsico Investment Fund (the "Trust") was organized on October 1, 1997,
     as a Delaware Statutory Trust and is registered under the Investment
     Company Act of 1940 (the "1940 Act") as an open-end management investment
     company. The Focus Fund, the Growth Fund, the 21st Century Fund and the
     International Opportunities Fund (collectively, the "Funds") are separate
     investment portfolios of the Trust. The Focus Fund is a non-diversified
     fund and the Growth Fund, the 21st Century Fund and the International
     Opportunities Fund are diversified funds. The Focus and Growth Funds
     commenced operations on December 31, 1997, the 21st Century Fund commenced
     operations on February 1, 2000 and the International Opportunities Fund
     commenced operations on June 30, 2000. Affiliates of the Adviser hold
     approximately 10% of the 21st Century Fund and 25% of the International
     Opportunities Fund.

2.   SIGNIFICANT ACCOUNTING POLICIES
     The following is a summary of significant accounting policies consistently
     followed by the Funds in the preparation of their financial statements.
     These policies are in conformity with generally accepted accounting
     principles ("GAAP") for investment companies. The presentation of financial
     statements in conformity with GAAP requires management to make estimates
     and assumptions that affect the reported amounts of assets and liabilities
     at the date of the financial statements and the reported amounts of income
     and expenses during the reporting period. Actual results could differ from
     those estimates. Certain prior year information has been reformatted to
     conform to the current year presentation.

     (a)  Investment Valuation-A security traded on a recognized stock exchange
          is valued at the last sale price prior to the time when assets are
          valued on the principal exchange on which the security is traded. If
          no sale is reported on the valuation date, the most current bid price
          will be used. All other securities for which over-the-counter market
          quotations are readily available are valued at the most current
          closing price. Debt securities that will mature in more than 60 days
          are valued at prices furnished by a pricing service. Securities that
          will mature in 60 days or less are valued at amortized cost, which
          approximates market value. Any securities for which market quotations
          are not readily available are valued at their fair value as determined
          in good faith by the Adviser in accordance with procedures established
          by, and under the general supervision of, the Trustees.

     (b)  Expenses-The Funds are charged for those expenses that are directly
          attributable to each Fund, such as advisory and custodian fees.
          Expenses that are not directly attributable to a Fund are typically
          allocated among the Funds in proportion to their respective net
          assets. The Funds' expenses may be reduced by voluntary advisory fee
          waivers, brokerage credits and uninvested cash balances earning
          interest or credits. Such credits are included in Waiver of Expenses
          and Expenses Paid Indirectly in the Statement of Operations.

          Brokerage commissions were paid to unaffiliated brokers which reduced
          certain transfer agent fees and expenses in the amount of $541,072 and
          $204,623 for the Focus Fund and Growth Fund, respectively, for the six
          months ended March 31, 2004. Also, the Funds received credits on
          certain custody account balances which reduced certain transfer agent
          fees and expenses in the amount of $2,582, $999, $157 and $46 for the
          Focus Fund, Growth Fund, 21st Century Fund and International
          Opportunities Fund, respectively, for the six months ended March 31,
          2004. Brokerage commission credits and custody account earnings
          credits are included in Expenses Paid Indirectly on the Statements of
          Operations.

     (c)  Federal Income Taxes-Each Fund intends to comply with the requirements
          of the Internal Revenue Code necessary to qualify as a regulated
          investment company and to make the requisite distributions of income
          to its shareholders which will be sufficient to relieve it from all or
          substantially all federal and state income and excise taxes.

     (d)  Distributions to Shareholders-Dividends from net investment income and
          net realized capital gains, if any, will be declared and paid at least
          annually. Distributions to shareholders are recorded on the ex-
          dividend date. Each Fund may periodically make reclassifications among
          certain of its capital accounts as a result of the timing and
          characterization of certain income and capital gains determined in
          accordance with federal tax regulations, which may differ from GAAP.
          These reclassifications are due to differing treatment for items such
          as deferral of wash sales, foreign currency transactions, net
          operating losses and post-October capital losses.

     (e)  Foreign Currency Translation-The accounting records of the Funds are
          maintained in U.S. dollars. Prices of securities denominated in
          foreign currencies are translated into U.S. dollars at the closing
          rates of exchange. Amounts related to the purchase and sale of foreign
          securities and investment income are translated at the rates of
          exchange prevailing on the respective dates of such transactions.

          Reported realized gains on foreign currency transactions arise from
          sales of portfolio securities, forward currency contracts, currency
          gains or losses realized between the trade and settlement dates on
          securities transactions, the difference between the amounts of
          dividends, interest, and foreign withholding taxes recorded on the
          Funds' books, and the U.S. dollar equivalent of the amounts actually
          received or paid.

          The Funds do not isolate that portion of the results of operations
          resulting from changes in foreign exchange rates on investments from
          the fluctuations arising from changes in market prices of securities
          held at fiscal year-end. Net unrealized appreciation or depreciation
          on investments and foreign currency translations arise from changes in
          the value of assets and liabilities, including investments in
          securities at fiscal year-end, resulting from changes in the exchange
          rates and changes in market prices of securities held.

     (f)  Forward Currency Contracts and Futures Contracts-The Funds may enter
          into forward currency contracts to reduce their exposure to changes in
          foreign currency exchange rates on their foreign holdings and to lock
          in the U.S. dollar cost of firm purchase and sale commitments for
          securities denominated in foreign currencies. A forward currency
          contract is a commitment to purchase or sell a foreign currency at a
          future date at a negotiated forward rate. The gain or loss arising
          from the difference between the U.S. dollar cost of the original
          contract and the value of the foreign currency in U.S. dollars upon
          closing of such contract is included in net realized gain or loss from
          foreign currency transactions.

          Forward currency contracts held by the Funds are fully collateralized
          by other securities. If held by the Funds, such collateral would be in
          the possession of the Funds' custodian. The collateral would be
          evaluated daily to ensure its market value equals or exceeds the
          current market value of the corresponding forward currency contracts.

          Futures contracts are marked to market daily and the resultant
          variation margin is recorded as an unrealized gain or loss. When a
          contract is closed, a realized gain or loss is recorded equal to the
          difference between the opening and closing value of the contract.
          Generally, open forward and futures contracts are marked to market
          (i.e., treated as realized and subject to distribution) for federal
          income tax purposes at fiscal year-end.

          Foreign-denominated assets and forward currency contracts may involve
          more risks than domestic transactions, including currency risk,
          political and economic risk, regulatory risk and market risk. Risks
          may arise from the potential inability of a counterparty to meet the
          terms of a contract and from unanticipated movements in the value of
          foreign currencies relative to the U.S. dollar.

          The Funds may enter into "futures contracts" and "options" on
          securities, financial indexes and foreign currencies, forward
          contracts, and interest rate swaps and swap-related products. The
          Funds intend to use such derivative instruments primarily to hedge or
          protect from adverse movements in securities prices, currency rates or
          interest rates. The use of futures contracts and options may involve
          risks such as the possibility of illiquid markets or imperfect
          correlation between the value of the contracts and the underlying
          securities, or that the counterparty will fail to perform its
          obligations.

     (g)  Options Contracts-The Funds may purchase and write (sell) put and call
          options on foreign and domestic stock indices, foreign currencies and
          U.S. and foreign securities that are traded on U.S. and foreign
          securities exchanges and over-the-counter markets. These transactions
          are for hedging purposes or for the purpose of earning additional
          income. In addition, the Funds may enter into such transactions for
          cross-hedging purposes.

          The risk associated with purchasing an option is that the Fund pays a
          premium whether or not the option is exercised. Additionally, the Fund
          bears the risk of loss of premium and change in market value should
          the counterparty not perform under the contract. Put and call options
          purchased are accounted for in the same manner as portfolio
          securities. The cost of securities acquired through the exercise of
          call options is increased by premiums paid. The proceeds from
          securities sold through the exercise of put options are decreased by
          the premiums paid.

          When the Fund writes an option, the premium received by the Fund is
          recorded as a liability and is subsequently adjusted to the current
          market value of the option written. Premiums received from writing
          options that expire are recorded by the Fund on the expiration date as
          realized gains from option transactions. The difference between the
          premium and the amount paid on effecting a closing purchase
          transaction, including brokerage commissions, is also treated as a
          realized gain, or if the premium is less than the amount paid for the
          closing purchase transaction, as a realized loss. If a call option is
          exercised, the premium is added to the proceeds from the sale of the
          underlying security or currency in determining whether the Fund has
          realized a gain or loss. If a put option is exercised, the premium
          reduces the cost basis of the security or currency purchased by the
          Fund. In writing an option, the Fund bears the market risk of an
          unfavorable change in the price of the security or currency underlying
          the written option. Exercise of an option written by the Fund could
          result in the Fund selling or buying a security or currency at a price
          different from the current market value.

     (h)  Trustees' Compensation-Effective February 1, 2000, the Board of
          Trustees adopted the Marsico Investment Fund Deferred Fee Plan (the
          "Plan") that allows the independent Trustees to defer the receipt of
          all or a portion of the Trustees' fees payable. The Trustees are
          deemed to be notionally invested in the Funds until distribution in
          accordance with the Plan. Included in the Trustees' Fees and Expenses
          on the Statement of Operations is the unrealized appreciation of
          $88,277, $60,026, $51,522 and $41,293 related to the mark-to-market of
          the shares of the deferred plan for the Focus Fund, Growth Fund, 21st
          Century Fund and International Opportunities Fund, respectively.

     (i)  Redemption Fee-For shares purchased on or after January 30, 2004, a
          2.00% redemption fee is retained by the Funds to offset transaction
          costs and other expenses associated with short-term investing. The fee
          is imposed on redemptions or exchanges of shares held 30 days or less
          from their purchase date. Prior to January 30, 2004, a 2.00%
          redemption fee was imposed on redemptions or exchanges of shares of
          the International Opportunities Fund held three months or less from
          their purchase date. Redemption fees are recorded by the Funds as a
          reduction of shares redeemed and as a credit to paid-in-capital. For
          the period January 30 (effective date) to March 31, 2004, the Focus
          Fund, Growth Fund and 21st Century Fund received $8,801, $2,230 and
          $812, respectively, in redemption fees. For the six months ended March
          31, 2004, the International Opportunities Fund received $16,873 in
          redemption fees.

     (j)  Other-Investment transactions are accounted for on a trade date basis.
          Each Fund determines the gain or loss realized from the investment
          transactions by comparing the original cost of the security lot sold
          with the net sale proceeds. Dividend income is recognized on the ex-
          dividend date. Certain dividends from foreign securities will be
          recorded as soon as the Trust is informed of the dividend if such
          information is obtained subsequent to the ex-dividend date. Interest
          income is recognized on an accrual basis.

          During the year ended September 30, 2003, the fund accounting agent
          reimbursed the 21st Century Fund $67,752 for an investment transaction
          loss, which had resulted from an unintended error in available cash
          balances for investment transactions. This reimbursement is included
          in the Statement of Operations and Financial Highlights as an Increase
          From Payment By Service Provider and did not have a significant effect
          on the Fund's total return.

3.   INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES
     The Funds have an agreement with Marsico Capital Management, LLC (the
     "Adviser") to furnish investment advisory services to the Funds. Under the
     terms of this agreement, the Adviser is compensated at the rate of 0.85% of
     the average daily net assets of each of the Focus, Growth, 21st Century and
     International Opportunities Funds. The Adviser has voluntarily agreed to
     limit the total expenses of each Fund (excluding interest, taxes, brokerage
     and extraordinary expenses) to an annual rate of 1.60% of the Focus and
     International Opportunities Funds' average daily net assets and 1.50% of
     the Growth and 21st Century Funds' average daily net assets until December
     31, 2004. This fee waiver is voluntary and may be terminated at any time.
     The voluntary waiver of expenses for the year ended September 30, 2003
     excludes as an extraordinary item the unrealized appreciation of $30,090
     and $17,937, respectively, for the 21st Century Fund and International
     Opportunities Fund. The unrealized appreciation is included in the Change
     in Unrealized Appreciation/Depreciation on Investment and Foreign Currency
     Translations on the Statement of Operations. As a result, the unrealized
     appreciation is retained by the Funds in accordance with the Plan. For
     periods subsequent to September 30, 2003, unrealized appreciation/
     depreciation of Fund shares in the Board of Trustees Deferred Fee Plan will
     be subject to the Funds' expense reimbursement agreement with the Adviser.

     The Adviser is entitled to reimbursement from a Fund of any fees waived
     pursuant to this arrangement if such reimbursements do not cause a Fund to
     exceed existing expense limitations and the reimbursement is made within
     three years after the year in which the Adviser incurred the expense. For
     the six months ended March 31, 2004, the Adviser recovered previously
     waived fees of $50,962 in the 21st Century Fund.

     As of March 31, 2004, the reimbursements that may potentially be made by
     the 21st Century Fund and the International Opportunities Fund to the
     Adviser are $153,474 and $403,141, respectively, which expire between 2004
     and 2006.

     Banc of America Securities is an affiliate of Marsico Capital Management,
     LLC and is designated as an introductory broker on certain Fund
     transactions. For the six months ended March 31, 2004, none of the Funds
     paid brokerage commissions to Banc of America Securities.

4.   SERVICE AND DISTRIBUTION PLAN
     The Funds have adopted a Service and Distribution Plan (the "Plan")
     pursuant to Rule 12b-1 under the 1940 Act. The Plan authorizes payments by
     the Funds in connection with the distribution of their shares at an annual
     rate, as determined from time to time by the Board of Trustees, of up to
     0.25% of a Fund's average daily net assets.

5.   INVESTMENT TRANSACTIONS
     The aggregate purchases and sales of securities, excluding short-term
     investments, for the Funds for the six months ended March 31, 2004, were as
     follows:

     International Opportunities Fund       58,910              20,986

     There were no purchases or sales of U.S. government securities.

6.   FEDERAL INCOME TAX INFORMATION
     At March 31, 2004, gross unrealized appreciation and depreciation of
     investments, based on cost for federal income tax purposes were as follows:

                                                          21st     International
                               Focus        Growth      Century    Opportunities
     (Amounts in thousands)    Fund          Fund         Fund         Fund
     ---------------------------------------------------------------------------
     Cost of investments    $2,325,429      $960,212      $172,946       $69,006

     Gross unrealized
       appreciation            517,351       228,231        28,679        12,312
     Gross unrealized
       depreciation           (30,524)       (9,917)         (968)         (231)
     Net unrealized
       appreciation
       on investments         $486,827      $218,314       $27,711       $12,081

     The difference between cost amounts for financial statement and federal
     income tax purposes is due primarily to wash sale loss deferrals and
     foreign currency transactions.

     The Focus Fund and Growth Fund had realized capital losses (in thousands)
     from transactions between November 1, 2002 and September 30, 2003 of
     $47,093 and $10,671, respectively.

     The Focus, Growth, 21st Century and International Opportunities Funds had
     realized currency losses (in thousands) from transactions between November
     1, 2002 and September 30, 2003 of $2,455, $26, $51 and $73, respectively.
     Post-October currency losses and capital losses are treated as arising in
     the Funds next fiscal year.

     At September 30, 2003, Focus, Growth, 21st Century and International
     Opportunities Funds had accumulated capital loss carryforwards (in
     thousands) of $329,779, $133,120, $63,078 and $6,683, with $0, $0, $34,555
     and $480 expiring in 2009, $242,309, $54,527, $28,523 and $6,125 expiring
     in 2010 and $87,470, $78,593, $0 and $78 expiring in 2011, respectively.
      To the extent that a fund may realize future net capital gains, those
     gains will be offset by any of its unused capital loss carryforward.

     The tax character of distributions paid during the fiscal years ended
     September 30, 2003, and September 30, 2002 were as follows (in thousands):

                                                          21st    International
