DEAR SHAREHOLDER:

Enclosed is your semiannual report for the Marsico Investment Fund encompassing
the six-month period from October 1, 2004 - March 31, 2005. In many senses, the
time period represents a "tale of two equity markets" - one (the fourth quarter
of calendar year 2004) generally positive in nature, the other (first quarter of
calendar year 2005) not nearly so positive. The purpose of this letter is to
provide a retrospective for the Funds' six-month investment results by
discussing what we believe are the main factors that impacted performance (e.g.,
sector positioning, industry allocations, and stock selection) as compared to
the Funds' benchmark indexes. Certain sector or industry classifications used in
this letter may be broader than those used elsewhere in this semiannual report.
For our updated thoughts regarding the market environment and our overall
investment outlook, please refer to the first quarter 2005 shareholder letter
dated April 2005 that we previously sent to you (which is also available on our
web site at www.marsicofunds.com).

MARSICO FOCUS FUND & MARSICO GROWTH FUND
- --------------------------------------------------------------------------------

INVESTMENT REVIEW BY TOM MARSICO

The Focus Fund and Growth Fund posted total returns of 7.22% and 5.96%,
respectively, for the six-month period ended March 31, 2005. For comparative
purposes, the S&P 500/R Index - which we consider to be the Funds' primary
benchmark index - had a total return of 6.88% over the same time period. The
Funds reached 7-1/4 years of operating history as of the end of March 2005.
Please see the Funds' overviews for more detailed information about each of the
Funds' performance for various periods ended March 31, 2005. The performance
data for the Funds quoted here represent 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.(1)

The six-month reporting period ended March 31, 2005, as mentioned earlier in
this report, in our opinion was essentially divided into two very different
quarters for the US equity markets - one with robust gains and generally
positive economic and financial developments; the other with negative returns
and a "wall of worry" built on (among other factors) higher interest rates,
inflation concerns, and rising energy prices. The two environments melded into a
period where US equity returns, as well as the performance of the Funds, may
appear quite solid on an absolute basis. However, it is very interesting to take
a few extra steps and further examine those results in order to better
understand their main underlying sources.

During the six-month period, nine of ten economic sectors (GICS classification)
in the S&P 500/R Index, the Funds' primary benchmark index, had a positive
return. That said, market leadership over the period was decidedly skewed
towards certain areas. The leading sectors, in terms of investment returns,
included Energy (+23%), Utilities (+18%), Materials (+10%), and Consumer Staples
(+9%). In general, leadership by these types of areas suggested to us that
equity investors grew somewhat more risk-averse during the overall reporting
period, particularly during the first quarter of 2005. Sectors that
traditionally have been considered more "growth-oriented" in nature - such as
Information Technology, Financials, Health Care, and Telecommunications Services
- - had lower returns than the S&P 500/R Index for the overall reporting period,
and struggled noticeably in the first quarter of 2005.

The performance of the Focus Fund and the Growth Fund during the past six months
was, on balance, similar to the S&P 500/R Index, and was characterized by
several



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

common factors. The Focus Fund and Growth Fund often invest in similar growth
companies. Their performance has differed at times, however, because the Focus
Fund invests in a relatively more concentrated portfolio of securities, while
the Growth Fund has held some positions that are not present in the Focus
Fund.(2)

The Funds' investment results were buoyed primarily by several factors that
included generally positive positioning and stock selection within the Health
Care sector (e.g., UnitedHealth Group, Genentech); several positions owned in
the Diversified Financials industry (e.g., SLM Corporation, Goldman Sachs
Group); several hotel/casino operator investments (e.g., Wynn Resorts, MGM
Grand); and an underweighted posture (as compared to the benchmark index) in two
areas - Information Technology and Insurance - whose returns were lower than the
overall equity market.(3)

There were several offsetting factors limiting investment results. The main
performance detriment for the Funds over the reporting period was our decision
to remain significantly underweighted in the Energy sector. This investment
posture created an "opportunity cost" for the Funds, as the Energy sector (with
a 23% gain) was the strongest-performing area over the past six months. Two
other factors that materially impacted performance were our stock selection in
the Banks and Retailing industries. More specifically, Countrywide Financial
(-17% during the six-month period) and eBay (-13% prior to being sold) were
among the Funds' weaker-performing individual holdings.(3)

As of March 31, 2005 the Funds' primary economic sector allocations were in
Health Care, Consumer Discretionary, Financials, and Industrials. The Funds had
modest or no exposure in areas such as Energy, Utilities, Materials, and
Telecommunications Services.

     owned for 30 days or less. See the prospectus for more information.

(2)  Because the Focus Fund may hold securities of fewer issuers than other
     diversified funds, the Fund is more exposed to individual stock volatility
     and market pressures than funds investing in a larger number of securities.

taxes on Fund distributions or the redemption of Fund shares.

MARSICO 21ST CENTURY FUND
- --------------------------------------------------------------------------------

INVESTMENT REVIEW BY CORY GILCHRIST

I am pleased to report that the 21st Century Fund had a total return of 9.71%
for the six-month period ended March 31, 2005. For comparative purposes, the S&P
500/R Index (which we consider to be the Fund's primary benchmark index),
Russell 3000 Index (a proxy for the performance of all publicly traded US
stocks, including smaller capitalization companies), and Nasdaq Composite Index
(consisting primarily of technology-related companies) had total returns of
6.88%, 7.73%, and 5.73%, respectively, over the same period. Please see the Fund
overview for more detailed information about the Fund's performance for various
periods ended March 31, 2005. The performance data for the Fund quoted here
represent 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.(1)

The Fund's performance during the six months ended March 31, 2005 benefited
primarily from stock selection in the Consumer Discretionary sector,
particularly those stocks in two industry groups: Hotels, Restaurants & Leisure;
and Media. The former category included holdings such as Wynn Resorts (+31%
during the six-month period), Shangri-La Asia (+36%), Las Vegas Sands (+55%),
and Kerzner International (+32%). As to the Fund's media-related holdings during
the reporting period, positions in Getty Images (+27% prior to being sold),
Dreamworks Animation (+44% prior to being sold), and Pixar (+15%) materially
enhanced performance.(2)

Several other individual holdings, spanning a variety of industries, also
contributed positively to the Fund's six-month return. These included Chicago
Mercantile Exchange (+21%), UnitedHealth Group (+29%), and Monsanto (+42% prior
to being sold).(2)

The main "Achilles heel" in terms of the Fund's performance was our decision to
have a limited number of investments in the Energy sector and an overall
underweighted posture in this sector as compared to the benchmark index. This
sector rose well over 20% during the past six months, and so our decision to
essentially remain "on the sidelines" detracted from the Fund's performance.

We also had some individual positions during the reporting period whose returns
were considerably lower than the Fund's benchmark index and significantly
detracted from performance. These included Harman International (-18%),
Countrywide Financial (-17%), and MarketAxess Holdings (+2%).(2)

The Fund has tended to have a relatively high portfolio turnover level because
of its investment style. Although the Fund may hold core positions for some
time, it may change its portfolio composition quickly to take advantage of new
opportunities, or to address issues affecting particular holdings.

In terms of economic sector distribution, the Fund maintained three areas of
emphasis as of March 31, 2005: Consumer Discretionary, Financials, and Health
Care. The Fund had a modest allocation to Energy as of the end of the reporting
period, and had few or no investments in Utilities, Materials, and
Telecommunications Services.

Sincerely,

/s/ Corydon J. Gilchrist

(1)  The performance returns for the 21st Century Fund (for the period prior to
     March 31, 2004) reflect a fee waiver in effect; in the absence of such a
     waiver, the returns would be reduced. For the period beginning April 1,
     2004, performance returns for the 21st Century Fund would be higher but for
     the reimbursement of fees waived previously. A redemption fee may be
     imposed on redemptions or exchanges of Fund shares owned for 30 days or
     less. See the prospectus for more information.

(2)  Portfolio composition is subject to change at any time and references to
     specific securities, industries and sectors referenced in this letter are
     not recommendations to purchase or sell any particular security. See the

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. A redemption fee may be imposed on
redemptions or exchanges of Fund shares owned for 30 days or less.

     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 21st Century Fund (for the period prior to
     March 31, 2004) reflect a fee waiver in effect; in the absence of such a
     waiver, the returns would be reduced. For the period beginning April 1,
     2004 performance returns for the 21st Century Fund would be higher but for
     the reimbursement of fees waived previously.

(2)  This chart assumes an initial investment of $10,000 made on February 1,
     2000 (inception). Total returns are based on net change in NAV, assuming
     reinvestment of distributions.

(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.

MARSICO INTERNATIONAL OPPORTUNITIES FUND
- --------------------------------------------------------------------------------

INVESTMENT REVIEW BY JIM GENDELMAN

The Marsico International Opportunities Fund had a (US$) total return of 9.69%
for the six-month period ended March 31, 2005. For comparative purposes, the
Morgan Stanley Capital International EAFE Index, which we consider to be the
Fund's primary benchmark index, had a total (US$) total return of 15.13% for the
same time period. Please see the Fund overview for more detailed information
about the Fund's performance for various periods ended March 31, 2005. The
performance data for the Fund quoted here represent 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.(1)

The Fund's six-month underperformance relative to its benchmark index was
primarily attributable to several factors:

- - CURRENCY:  In the context of a generally weakening US dollar over the six
  months ended March 31, 2005, the Fund's exposure to dollar-based assets
  (e.g., American Depositary Receipts, cash equivalents), and companies whose
  "home currency" correlates generally with the value of the dollar, had a
  substantial negative performance impact.

- - MEDIA POSITIONS:  The Fund's media holdings, collectively, had a positive
  return but struggled in comparison to the Fund's benchmark index. During the
  reporting period, the Fund's media positions had a collective price return of
  7%, while the benchmark index's Media industry group return was 19%. Specific
  individual holdings that impacted performance in relation to the benchmark
  index included NTL (+3%), Sogecable (-4%), Reuters Group (+6%), and News
  Corp., Ltd. (+7%).(2)

- - INFORMATION TECHNOLOGY:  Our stock selection in this sector was mixed during
  the reporting period. In particular, positions such as LM Ericsson Telephone
  (-12%), Trend Micro (-16%), and Research In Motion (-2%) had returns that
  materially impacted the Fund's performance. The Fund did have some strong-
  performing holdings in this sector, such as Samsung Electronics (+26%) and
  Canon (+15%). However, these were not enough to fully offset the impact of
  the Fund's less strong holdings.(2)

- - ENERGY:  During the reporting period, we increased the Fund's energy-related
  holdings rather significantly, based - in part - on our assessment of several
  unique opportunities at the individual company level. For the entire
  reporting period, the Fund's positions in this sector had an aggregate return
  of 9%, compared to the benchmark index's sector return (+17%). The Fund's
  position in Total (+17%) was among its better-performing individual holdings.
  However, Petroleo Brasileiro (-8%), Golar Lng



  (-11% prior to being sold), and Sasol (-1%) had the overall impact of
  moderating the Fund's gains in the Energy sector.(2)

The Fund has tended to have a relatively high portfolio turnover level because
of its investment style. Although the Fund may hold core positions for some
time, it may change its portfolio composition quickly to take advantage of new
opportunities, or to address issues affecting particular holdings.

As of March 31, 2005 the Fund's holdings, in terms of economic sector
distribution, were allocated primarily to Financials, Consumer Discretionary,
and Energy. During the reporting period, we reduced the Consumer Discretionary
positions quite substantially, primarily in industry groups such as Media and
Retailing. The Financials weighting rose, and included new investments in
Insurance and Real Estate. The Fund's largest country-level allocations as of
the end of the reporting period were in Japan, the United Kingdom, Switzerland,
France, and Canada.

Sincerely,

(1)  The performance returns for the International Opportunities Fund (for the
     period prior to September 30, 2004) reflect a fee waiver in effect; in the
     absence of such a waiver, the returns would have been reduced. For the
     period beginning October 1, 2004, performance returns for the International
     Opportunities Fund would be higher but for the reimbursement of fees waived
     previously. A redemption fee may be imposed on redemptions or exchanges of
     Fund shares owned for 30 days or less. See the prospectus for more
     information. Foreign investments present additional risks due to currency
     fluctuations, economic and political factors, lower liquidity, government
     regulations, differences in securities regulations and accounting
     standards, possible changes in taxation, limited public information and
     other factors.

     The Morgan Stanley Capital International EAFE Index tracks the stocks of
     about 1,000 companies in Europe, Australasia, and the Far East (EAFE). You

MARSICO FUNDS

NOTES TO FINANCIAL STATEMENTS MARCH 31, 2005 (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 6% of the 21st Century Fund and 10% 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.

     (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 Funds' Board of
          Trustees. The Funds may use pricing services to determine market
          value. The Board of Trustees has authorized the use of a pricing
          service to assist the Funds in valuing certain equity securities
          listed or traded on foreign security exchanges in the Funds'
          portfolios in certain circumstances where there is a significant
          change in the value of related U.S.-traded securities, as represented
          by the S&P 500/R Index.

     (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 $641,453 and
          $153,955 for the Focus Fund and Growth Fund, respectively, for the six
          months ended March 31, 2005. Also, the Funds received credits on
          certain custody account balances which reduced certain transfer agent
          fees and expenses in the amount of $5,174, $2,602, $517 and $247 for
          the Focus Fund, Growth Fund, 21st Century Fund and International
          Opportunities Fund, respectively, for the six months ended March 31,
          2005. 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. Certain
          Funds may utilize earnings and profits on redemption of shares as part
          of the dividends paid deduction.

     (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, deferred trustees compensation, 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 4:00 p.m. ET.
          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

NOTES TO FINANCIAL STATEMENTS MARCH 31, 2005 (UNAUDITED) (continued)

     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. Transactions in call options written for the six
     months ended March 31, 2005 were as follows:

     (h)  Trustees' Compensation-Effective February 1, 2000, the Board of
          Trustees adopted the Marsico Investment Fund Deferred Fee Plan (the
          "Deferred Fee 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 Deferred Fee Plan. Included in the
          Trustees' Fees and Expenses on the Statement of Operations is the
          unrealized appreciation of $10,090, $16,362, $8,787 and $4,050 related
          to the mark-to-market of the shares of the Deferred Fee 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 six months ended March 31, 2005, the Focus Fund, Growth Fund, 21st
          Century Fund and International Opportunities Fund received $18,513,
          $28,692, $27,289 and $5,429, respectively, 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 Financial Highlights as an Increase From Payment By Service
          Provider.

     

     (k)  Indemnifications-In the normal course of business, the Funds enter
          into contracts that contain provisions indemnifying other parties
          against specified potential liabilities. Each Fund's maximum exposure
          under these arrangements is unknown as this would involve future
          claims that may be made against the Fund that have not yet occurred.
          However, based on experience, the Funds expect the risk of loss to be
          remote.

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. Effective November 11, 2004, the Adviser
     reduced its investment advisory fee ("management fee") for managing the
     Focus Fund and Growth Fund for assets that exceed certain thresholds. The
     current management fee schedule for these two Funds is 0.85% per year of
     average daily net assets up to $3 billion in each Fund, and 0.75% per year
     of average daily net assets exceeding $3 billion in each Fund. 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, 2005. 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 related to the mark-to-market of
     the shares of the Deferred Fee Plan. 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 Deferred Fee Plan. For periods subsequent to
     September 30, 2003, unrealized appreciation/depreciation of Fund shares in
     the 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, 2005, the Adviser recovered previously
     waived fees of $98,548 and $111,946, respectively, in the 21st Century Fund
     and International Opportunities Fund.

     As of March 31, 2005, the reimbursement that may potentially be made by the
     International Opportunities Fund to the Adviser is $192,624, which expires
     in 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, 2005, 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, 2005, were as
     follows:

     (Amounts in thousands)                   Purchases                  Sales

     Growth Fund                                853,295                589,795
     21st Century Fund                          318,049                180,086
     International Opportunities Fund           235,382                140,356

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

6.   FEDERAL INCOME TAX INFORMATION
At March 31, 2005, gross unrealized appreciation and depreciation of
investments, based on cost for federal income tax purposes were as follows:

  on investments                $672,952     $338,453     $39,085     $12,189

- --------------------------------------------------------------------------------
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, Growth, 21st Century and International Opportunities Funds had
realized currency losses (in thousands) from transactions between November 1,
2003 and September 30, 2004 of $1,068, $9, $401 and $173, respectively. Post-
October currency losses and capital losses are treated as arising in the Funds'
next fiscal year.

At September 30, 2004, the Focus, Growth, 21st Century and International
Opportunities Funds had accumulated capital loss carryforwards (in thousands) of
$293,243, $133,048, $50,674 and $5,843, with $0, $0, $22,151 and $0 expiring in
2009, $205,773, $54,455, $28,523 and $5,765 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 Focus, Growth, 21st Century and International Opportunities Funds utilized
$36,536, $72, $12,404 and $840, respectively, of its capital loss carryforwards
during the year ended September 30, 2004.

As of September 30, 2004, the components of accumulated earnings (deficit) on a

EXPENSE EXAMPLE FOR THE SIX MONTHS ENDED MARCH 31, 2005 (UNAUDITED)

As a shareholder of the Marsico Funds (the "Funds"), you incur two types of
costs: (1) transaction costs, including redemption fees on certain redemptions;
and (2) ongoing costs, including management fees; distribution (12b-1) fees, and
other Fund expenses. This Example is intended to help you understand your
ongoing costs (in dollars) of investing in the Funds and to compare these costs
with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period from October 1, 2004 to March 31, 2005
(the "period").

ACTUAL EXPENSES

The first line of 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 you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 equals 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 the period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Funds' actual expense
ratios and an assumed rate of return of 5% per year before expenses, which is
not the actual return of any of the Funds. 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 Funds 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 transactional costs, such as
redemption fees. Therefore, the second line of the table is useful in comparing
the 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 could have been higher.

ANNUAL RENEWAL OF INVESTMENT
ADVISORY AGREEMENTS
At a meeting of the Board of Trustees of the Trust that commenced on November
10, 2004 and concluded on November 11, 2004, the Trustees, by a unanimous vote
(including a separate vote of those Trustees who are not "interested persons"
(as the term is defined in the 1940 Act) (the "Independent Trustees"), approved
the renewal of the Funds' Investment Advisory Agreements (the "Agreements"). In
advance of the meeting, the Independent Trustees requested and received
extensive materials from the Adviser to assist them in considering the renewal
of the Agreements. The materials provided by the Adviser contained information
with respect to the factors noted below, including detailed comparative
information relating to the performance, advisory fees and other expenses of the
Funds, other funds sub-advised by the Adviser and non-fund advisory accounts of
the Adviser. The materials also included comparisons of the Funds with other
funds and non-fund accounts of similar size and investment objectives in terms
of performance, fees and other expenses, as well as the performance of each Fund
versus its benchmark. In addition, the Adviser provided information regarding
its overall expenses and profitability, as well as estimates of its costs and
profitability relating to managing the Funds.

In addition to the materials prepared specifically for contract review analysis,
on an ongoing basis the Trustees receive information and reports from the
Adviser and other service providers to the Funds on investment performance as
well as operational, compliance and other matters.

The Trustees engaged in a detailed discussion of the materials with management
of the Adviser. The Independent Trustees then met separately with independent
counsel to the Independent Trustees for a full review of the materials.
Following this session, the full Board reconvened and approved the continuation
of the Agreements.

DISCUSSION OF FACTORS CONSIDERED

In connection with the re-approval of the Agreements, the Trustees, including
the Independent Trustees, requested and received from the Adviser, and reviewed,
a wide variety of information, including information about (1) the nature,
extent, and quality of the services provided by the Adviser; (2) the investment
performance of the Funds and the Adviser; (3) the costs of the services to be
provided and profits realized by the Adviser and its affiliates from the
relationship with the Funds; (4) the extent to which economies of scale may be
realized as the Funds grow; and (5) whether fee levels reflect these economies



of scale for the benefit of Fund investors; as well as other relevant
considerations such as the management fees and expense ratios of each Fund;
potential fall-out benefits to the Adviser from its relationship to each Fund;
and other general information about the Adviser. The following is a summary of
the Board's discussion and views regarding these factors:

1.   NATURE, EXTENT, AND QUALITY OF SERVICES.
     The Trustees considered the nature, quality and extent of administrative
     and shareholder services performed by the Adviser, including portfolio
     management, supervision of Fund operations and compliance and regulatory
     filings and disclosures to shareholders, general oversight of other service
     providers, coordination of Fund marketing initiatives, review of Fund legal
     issues, assisting the Trustees in that capacity and other services. The
     Trustees concluded that the services are extensive in nature and that the
     Adviser consistently delivered a high level of service.

2.   INVESTMENT PERFORMANCE OF THE FUNDS AND ADVISER.
     The Trustees considered short-term and long-term investment performance for
     each Fund over various periods of time as compared to both relevant equity
     indices and the performance of such Fund's Lipper, Inc. peer group
     universe, and concluded that the Adviser was delivering superior
     performance results consistent with the long-term investment strategies
     being pursued by the Funds. The Trustees also noted that the strong
     investment performance delivered by the Adviser to the Funds appeared to be
     consistent with the performance delivered for other clients of the Adviser.

3.   COSTS OF SERVICES AND PROFITS REALIZED BY THE ADVISER.
     (a)  Costs of Services to Funds:  Fees and Expenses. The Trustees
          considered each Fund's management fee rates and expense ratios
          relative to industry averages for such Fund's benchmark category and
          the advisory fees charged by the Adviser to other sub-advised funds
          and non-fund clients, including information regarding expense
          limitation commitments from the Adviser, and the actual and proposed
          breakpoints for the Fund's advisory services. The Trustees noted that
          the mix of services under the Agreements are much more extensive than
          those under the Adviser's advisory agreements for sub-advised funds as
          well as non-fund clients. While the Trustees noted that the investment
          advisory fees paid by the Funds are generally in the upper quartile of
          their peer groups, they concluded that those fees are acceptable based
          upon the qualifications, experience, reputation, and performance of
          the Adviser and the low-to-moderate overall expense ratios of the
          Funds.

     (b)  Profitability and Costs of Services to Adviser. The Trustees
          considered the Adviser's overall profitability and costs and a pro
          forma estimate of the Adviser's profitability and costs if the Funds
          constituted the Adviser's only assets under management. The Trustees
          also considered whether the amount of profit is a fair entrepreneurial
          profit for the management of each Fund, and noted that the Adviser has
          substantially increased its resources devoted to Fund matters in
          response to recently-enacted regulatory requirements and new or
          enhanced Fund policies and procedures. The Trustees concluded that the
          Adviser's profitability was at an acceptable level, particularly in
          light of the high quality of the services being provided to the Funds.

4.   EXTENT OF ECONOMIES OF SCALE AS FUNDS GROW.
     The Trustees considered whether there have been economies of scale with
     respect to the management of each Fund and whether such Fund has
     appropriately benefited from any economies of scale. Economies of scale may
     develop for certain Funds as their assets increase and their Fund-level
     expenses decline as a percentage of assets. Fund-level economies of scale
     may not necessarily result in Adviser-level economies of scale, however.
     The Adviser explained that the expenses incurred by the Adviser relating to
     management of the Funds have increased substantially in recent years as a
     percentage of management fees, rather than declining as might be
     anticipated as the assets of certain Funds increase. The Adviser and the
     Independent Trustees agreed that it was possible that Adviser-level
     expenses incurred in managing the Funds eventually may level off or decline
     as a percentage of management fees, especially if the assets of certain
     Funds continue to grow beyond certain thresholds.

5.   WHETHER FEE LEVELS REFLECT ECONOMIES OF SCALE.
     The Trustees also considered whether the management fee rate is reasonable
     in relation to the asset size of each Fund and any economies of scale that
     may exist. In response to a previous suggestion by the Independent Trustees
     that the Adviser consider whether breakpoints might be appropriate



- --------------------------------------------------------------------------------
MARSICO FUNDS

     at some level, the Adviser proposed that, effective November 11, 2004,
     breakpoints be introduced for the two larger Funds, the Focus Fund and the
     Growth Fund, for assets that grow beyond $3 billion in each Fund. Under the
     proposed breakpoints, investment management fees will be 0.85% per year of
     average daily net assets up to $3 billion in each of those two Funds, and
     0.75% per year of average daily net assets exceeding $3 billion in each
     Fund. The Independent Trustees noted that the Adviser had responded
     positively to their recommendation that the investment management fees for
     certain Funds be reconsidered, and approved the proposed new fee schedule.

6.   OTHER RELEVANT CONSIDERATIONS.
     (a)  Adviser Personnel and Methods. The Trustees considered the size,
          education and experience of the Adviser's staff, the Adviser's
          fundamental research capabilities and the Adviser's approach to
          recruiting, training and retaining portfolio managers and other
          research and management personnel, and concluded that in each of these
          areas the Adviser was structured in such a way to support the high
          level of services being provided to the Funds.

     (b)  Other Benefits to the Adviser. The Trustees also considered the
          character and amount of other incidental benefits received by the
          Adviser and its affiliates from its association with the Funds. The
          Trustees concluded that potential "fall-out" benefits that the Adviser
          may receive, such as greater name recognition or increased ability to
          obtain research or brokerage services, appear to be reasonable, and
          may in some cases benefit the Funds.

CONCLUSIONS

All of these factors were considered by the Trustees at large, and also were
considered by the Independent Trustees meeting separately with independent legal
counsel. In considering the Agreements, the Trustees did not identify any factor
as all-important or all-controlling and instead considered these factors
collectively in light of each Fund's surrounding circumstances. Based on this
review, it was the judgment of the Trustees and the Independent Trustees that
shareholders had received very favorable absolute and relative performance at
reasonable fees and, therefore, re-approval of the Agreements was in the best
interests of each Fund and its shareholders. As a part of its decision-making
process, the Trustees noted that the Adviser has managed the Funds since their
inception, and the Trustees believe that a long-term relationship with a
capable, conscientious adviser is in the best interests of the Funds. The
Trustees considered, generally, that shareholders invested in a Fund knowing
that the Adviser managed that Fund and knowing its investment management fee
schedule. As such, the Trustees considered, in particular, whether the Adviser
managed each Fund in accordance with its investment objectives and policies as
disclosed to shareholders. The Trustees concluded that each Fund was managed by
the Adviser consistent with its investment objectives and policies.
