OCTOBER 2005

DEAR SHAREHOLDER:

Enclosed is your fiscal year 2005 annual report for the Marsico Investment Fund
encompassing the one-year period from October 1, 2004 - September 30, 2005.
Stock prices worldwide were quite strong overall during this period, as the most
widely watched US benchmark equity indexes experienced significant positive
returns, and international equity performance results were even better.

The purpose of this report is to provide a retrospective for the Funds'
investment results for fiscal year 2005 by discussing the main factors that
impacted performance - 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 annual report. For our updated thoughts regarding the market
environment and our overall investment outlook, please refer to the quarterly
shareholder update dated October 2005 that is available on the Funds' website

MARSICO FOCUS FUND & MARSICO GROWTH FUND

INVESTMENT REVIEW BY TOM MARSICO (UNAUDITED)

I am pleased to report that both the Focus Fund and Growth Fund outperformed
their primary benchmark index for the one-year period ended September 30, 2005.
The Focus Fund posted a total return of 17.67% and the Growth Fund returned
13.42% for this period. By comparison, the S&P 500(R) Index - which we consider
to be the Funds' primary equity benchmark - had a total return of 12.25% for the
one-year period ended September 30, 2005. The Funds reached 7-3/4 years of
operating history as of the end of September. Please see the Funds' overviews
for more detailed information about each Fund's longer-term performance for
various periods ended September 30, 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

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

In assessing the Funds' performance over the past year, it is interesting to
"decompose" the S&P 500(R) Index's return. Much of the Index's 12%-plus gain for
the reporting period was achieved in the fourth calendar quarter of 2004, when
it rose by about 9%. In the first nine months of calendar year 2005, the
investment landscape seemed to shift. Over that nine-month time frame, the S&P
500(R) Index was able to eke out a gain of less than 4%. US equities generally
seemed to have been stalled by a variety of concerns through the first nine
months of calendar year 2005. These included higher energy prices, higher
inflation expectations, a possible slowdown in consumer spending, and growing
unease about rising housing markets.

In the past year, there were a few interesting aspects of the US and
international equity markets:

     o    In the large-capitalization  equity arena, "value" stocks outperformed
          "growth"  stocks.  The Russell 1000 Value Index,  which is intended to
          provide a  representation  of the performance of major companies whose
          stocks trade at relatively low valuations, had a total one-year return
          of 17.69% for the period ended  September  30, 2005.  The Russell 1000
          Growth Index,  which is intended to be a proxy for the  performance of
          large-capitalization  growth-oriented  companies, had a total one-year
          return  of  11.60%  over the  same  period.  Much of the  differential
          between  the two  investment  styles  was  attributable  to the higher
          weighting of energy-related companies in the value index. As discussed
          later, the S&P 500(R) Index's Energy sector had a return of nearly 50%
          for the one-year period ended September 30, 2005.

     o    Medium-   and    small-capitalization    stocks   outperformed   large
          capitalization  stocks for the  one-year  period ended  September  30,
          2005. The largest-sized  companies,  as represented by the performance
          of the  Russell  Top 50  Index,  had a return of  7.31%.  The  Russell
          Mid-Cap Index,  which is intended to provide a representation  for the
          performance of  medium-sized  companies,  had a return of 25.10%.  The
          Russell  2000  Index,  a proxy  for  the  performance  of  small-sized
          companies, gained 17.95%.

     o    Non-US  stocks  were "the place to be" last year.  The MSCI EAFE Index
          had a total return of (US$) 25.79%. Results in "emerging" markets were
          even better.


At the economic sector level, gains over the full one-year period were
widespread. All 10 Global Industry Classification Standard industry sectors
("GICS") that comprise the S&P 500(R) Index had a positive return. As is often
the case, there was a considerable range of results; the "spread" between the
top- and bottom-performing sectors was more than 45%. Energy, which soared by
48%, was the top-performing sector in the S&P 500(R) Index for the one-year
period ended September 30, 2005. Other sectors that generated strong returns
included Utilities (+39%), Information Technology (+13%), and Health Care
(+10%). Several sectors had relatively modest gains, including Materials (+2%)
and Telecommunications Services (+2%).

At an industry group level, there also was quite a bit of variance in returns.
Several industries, quite diverse in nature, had robust gains. These included
Real Estate (+29%), Semiconductors and Semiconductor Equipment (+26%), Health
Care Equipment and Services (+24%), and Food, Beverage & Tobacco (+21%). There
were not many areas "in the red" last year. One exception was Automobiles &
Components (-21%), which struggled due to a variety of industry-wide issues.

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

Following is a synopsis of each Fund's investment results for the fiscal year:

FOCUS FUND

The Focus Fund's outperformance for the one-year period ended September 30, 2005
(as compared to the S&P 500(R) Index) was attributable to several factors:


     o    Health  Care  - Two of  the  Fund's  largest  individual  positions  -
          Genentech and UnitedHealth  Group - gained 61% and 52%,  respectively,
          over the reporting period. (3)

     o    Diversified  Financials - The Fund's  positions in this industry group
          had a collective  return of 32% in fiscal year 2005. Two of the Fund's
          holdings,  Chicago Mercantile  Exchange (+95%) and Goldman Sachs Group
          (+32%)   were  among  the  Fund's   largest   individual   performance
          contributors  taking  into  account  their  price  returns and average
          position sizes in the Fund.

     o    Information  Technology  - The  Fund's  results  were  helped by stock
          selection in two industry groups within this sector. In the Hardware &
          Equipment  area,  Apple  Computer  had a price  return of 42% prior to
          being  sold and  QUALCOMM  gained  16%.  Google,  which is  classified
          officially as a Technology Software & Services company, rose 45%.

     o    Utilities - TXU Corporation gained 90%.

     o    Capital Goods - Caterpillar posted a gain of 49%.

     o    Media - The Fund's underweighted  posture in this industry contributed
          materially  to overall  investment  results.  Media,  which eked out a
          modest   gain  of  2%  in  the   benchmark   index,   was   among  the
          weaker-performing industry groups last year.

The main areas that detracted materially from the Fund's performance over the
past year were our stock selection in the Consumer Services industry group
(particularly the hotel/casino operators and leisure-related holdings), an
underweighted posture in the Energy sector, and select holdings in the Banks
industry (most notably Countrywide Financial Corporation).



MARSICO FOCUS FUND & MARSICO GROWTH FUND

GROWTH FUND

The Growth Fund shared some of the Focus Fund's performance characteristics for
the one-year period ended September 30, 2005. Sectors and industry groups such
as Health Care, Utilities, Diversified Financials, Capital Goods, and Technology
Software & Services were significant value-added contributors, as was an
underweighted posture in the Media industry, which was among the
weaker-performing areas of the market. In addition, the Growth Fund benefited
significantly from many of its homebuilding-related positions. Several of these
factors are discussed below in a bit more detail:

     o    Health Care - Stock selection in this industry group was a significant
          positive  contributor to  performance.  In  particular,  biotechnology
          company  Genentech  gained 61% during the reporting  period and health
          care services provider UnitedHealth Group rose 52%. (3)

     o    Diversified  Financials - Chicago  Mercantile  Exchange  (+105%),  SLM
          Corporation  (+22%),  Merrill  Lynch & Co. (+18% prior to being sold),
          and   Lehman   Brothers   Holdings   (+18%)   were  among  the  Fund's
          better-performing individual holdings.

     o    Homebuilding - A variety of the Fund's  homebuilding stocks had strong
          stock price performance,  including KB Homes (+80%), MDC Corp. (+42%),
          Toll Brothers (+35%), and Lennar Corp. (+27%). In a related vein, home
          improvement retailer Lowe's Cos. (+19%) also had solid performance.

     o    Capital Goods - Caterpillar posted a gain of 49%.

     o    Technology Software & Services - Google had a return of 47%.

     o    Utilities - TXU Corporation had a return of 49%.

The primary negative performance factors for the Growth Fund for the one-year
period ended September 30, 2005 were similar to those impacting the Focus Fund.
They included:

     o    An underweighted  posture in Energy - The Fund did not have any direct
          positions in the Energy  sector.  As discussed  earlier,  Energy (+48%
          return) was the  strongest-performing  sector in the S&P 500(R)  Index
          for the one-year period ended September 30, 2005. The Fund sustained a
          substantial  "opportunity  cost" because of our decision to not invest
          significantly in this sector.

     o    Stock selection in the Consumer  Services industry - As in the case of
          the Focus Fund,  stock  selection  in this  industry  group  adversely
          impacted  the  Growth   Fund's  fiscal  year   performance.   Specific
          individual holdings that materially impacted performance included Wynn
          Resorts (-13%) and Four Seasons Hotels (-10%).

     o    Information  Technology  - The Growth  Fund did not benefit as much as
          the Focus Fund from  investments in this sector,  particularly  in the
          Hardware & Equipment  industry  where the Fund held several  positions
          that did not perform  particularly  well and were sold. These included
          Dell Computer  (0%), L M Ericsson  (-7%),  Adobe Systems  (-16%),  and
          Cisco Systems (-5%). The Fund did have positions in QUALCOMM and Apple
          Computer which  performed well in terms of overall  returns.  However,
          the Growth Fund's average position size in QUALCOMM was less than that
          in the Focus Fund, which mitigated some of its positive return impact.
          Apple Computer (+24%) was held for a different  period of time than in
          the Focus Fund, and also was a somewhat  smaller-sized position in the
          Growth  Fund.  As a result it did not have the same degree of positive
          impact on the Growth Fund as it did on the Focus Fund.



FISCAL YEAR-END INVESTMENT POSTURE

As of September 30, 2005 the Funds' primary economic sector allocations were in
Health Care, Consumer Discretionary, Financials, Industrials, and Information
Technology. The Funds had little or no exposure in areas such as Materials and
Telecommunications Services.

The performance data quoted here represents past performance, and past
performance is not a guarantee of future results. Investment return and

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

    of taxes on Fund distributions or the redemption of Fund shares.

MARSICO 21ST CENTURY FUND

INVESTMENT REVIEW BY CORY GILCHRIST (UNAUDITED)

I am pleased to report that the 21st Century Fund outperformed its primary
benchmark index for the one-year period ended September 30, 2005. The 21st
Century Fund had a total return of 18.33% for this period. For comparative
purposes, the S&P 500(R) Index (which we consider to be the Fund's primary
benchmark index), the Russell 3000 Index (a proxy for the performance of all
publicly traded U.S. stocks, including smaller capitalization companies), and
the NASDAQ Composite Index (consisting primarily of technology-related
companies) had total returns of 12.25%, 14.57%, and 14.19%, respectively, over
the same period. Please see the Fund overview for more detailed information
about the Fund's longer-term performance for various periods ended September 30,
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 primary areas that helped buoy the Fund's performance for the one-year
period ended September 30, 2005 included:

     o    Pharmaceutical  &  Biotechnology   companies  -  This  industry  group
          provided  excellent  overall returns for the Fund last year.  Specific
          holdings that performed well include  Amylin  Pharmaceuticals  (+86%),
          Genentech  (+61%),  and  Roche  Holdings  (+20%).  Amylin's  principal
          activity is to discover,  develop,  and market drug candidates for the
          treatment   of  diabetes,   obesity,   and   cardiovascular   disease.
          Genentech's  principal  activities  are  to  discover,   develop,  and
          manufacture   biotherapeutic   treatments  for  unmet  medical  needs,
          including cancer,  heart attacks,  and asthma.  Roche Holdings is also
          focused  on   providing   health  care   solutions,   principally   in
          pharmaceuticals and diagnostics. Roche owns 55.5% of Genentech. (2)

     o    Media - The Fund held two positions for part of the reporting period -
          Dreamworks  Animations  (+44%)  and  Pixar  (+15%) - that  contributed
          positively  to  overall  investment  results.   Another  media-related
          holding that helped performance was Getty Images, an e-commerce visual
          content  company whose products  include news and sports  photography,
          which gained 35% during the fiscal year.

     o    Diversified  Financials  -  Stock  selection  in this  industry  had a
          material  positive  effect on the Fund's  performance.  In particular,
          investment  results  were buoyed by  positions  in Chicago  Mercantile
          Exchange (+111%) and Jefferies Group (+28%).

     o    Materials - A position in Monsanto  (+42% prior to being sold)  helped
          performance.   Monsanto  is  an  agricultural  products  company  that
          produces  seed brands and  develops  biotechnology  traits that assist
          farmers in controlling insects and weeds.

     o    Technology Software & Services - Google rose 42%.

     o    Consumer  Staples -  Holdings  in Dean Foods  (+32%)  and Whole  Foods
          Market  (+56% prior to being  sold)  helped  performance.  Dean Foods'
          principal  activity is to process and distribute  fresh milk and other
          dairy  products.  Whole Foods  Market  operates a chain of natural and
          organic food supermarkets.




MARSICO 21ST CENTURY FUND

Although the Fund's overall return for the year surpassed its primary benchmark
indexes, there were certain factors that detracted significantly from investment
results and should be mentioned:

     o    Underweighted  Posture in the Energy sector - As discussed  earlier in
          this report, Energy was the best-performing economic sector in the S&P
          500(R) Index for the one-year  period ended September 30, 2005. In the
          Russell 3000 Index, the Energy sector gained 52% over that period.  As
          in  the  case  of  the  Focus  and  Growth  Funds,  we  elected  to be
          substantially  underweighted,  as compared  to our  primary  benchmark
          index, in energy-related companies. As a result, the 21st Century Fund
          absorbed a substantial "opportunity cost."

     o    Banking Positions - Countrywide  Financial Corporation (-16%) and UCBH
          (-6%) were among the Fund's weaker-performing individual holdings last
          year.

     o    Diversified  Financials  Positions - On the whole, the Fund's holdings
          in this  industry  added  value.  However,  there were a few  clunkers
          during  the  reporting   period.   Most  notably,   First   Marblehead
          Corporation,  a provider of outsourcing services for private education
          lending, declined -63% prior to being sold.

     o    Real Estate  Positions - This  industry  was among the  top-performing
          industry  groups  last  year.  We had the right  idea in  having  some
          positions in this area.  However,  our stock selection,  in aggregate,
          detracted from investment results.  The Fund's holdings included three
          real estate  investment  trusts ("REITs") - Redwood Trust (-10%),  KKR
          Financial Group (-9%), and Government  Properties Trust (+10%) - whose
          returns trailed the benchmark.  In addition,  St. Joe  Corporation,  a
          Florida-based  land developer,  declined by -2% for the period.  While
          that loss was modest, it was magnified by the substantial average size
          of the  position in the Fund.  Further-  more,  St.  Joe's  return was
          considerably behind the industry benchmark's overall return.

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.

FISCAL YEAR-END INVESTMENT POSTURE

As of September 30, 2005 the Fund's holdings primarily emphasized five economic
sectors. These included: Financials, Consumer Discretionary, Health Care,
Industrials, and Information Technology. The Fund had few or no investments in
Telecommunications Services, Materials, and Utilities.

Sincerely,

CORYDON J. GILCHRIST

     waiver, the returns would be reduced. For the period April 2004 through
     January 2005, 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.

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 April 2004 through
    January 2005, 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 (UNAUDITED)

The Marsico International Opportunities Fund had a (US$) return of 22.30% for
the one-year period ended September 30, 2005. For comparative purposes, the MSCI
EAFE Index ("EAFE Index"), which we consider to be the Fund's primary benchmark
index, had a total (US$) return of 25.79% for the same time period. Please see
the Fund overview for more detailed information about the Fund's longer-term
performance for various periods ended September 30, 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

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

International equity markets in developed markets were remarkably strong over
the last year. Asian markets had robust gains. Japan was up 27% in dollar terms.
Hong Kong stocks rose 24% and Singapore securities advanced by 19%. Continental
Europe also posted strong overall returns. As examples, Germany and the United
Kingdom had returns of 26% and 21%, respectively, during the reporting period.

Within the EAFE Index, economic sector strength abounded. All 10 sectors (GICS
classification) that comprise the Index had returns that were solidly in
positive territory. Three sectors rose by 30% or more, including Energy (+39%),
Materials (+37%), and Industrials (+32%). Six other sectors had gains of
25%-plus. The "laggard" sector (note the quotation marks) was Information
Technology, which had a relatively modest increase - as compared to the rest of
the sectors - of 13%. A similar story of strength unfolded at the industry group
level. All 20 industries represented in the EAFE Index had positive returns last
year. Just one group, Semiconductors and Semiconductor Equipment, had a gain of
less than 10%.

Overall, the Fund's return for the one-year period ended September 30, 2005
lagged only modestly behind its benchmark index. The Fund had a significant
allocation to Japan throughout that period (19% as of September 30, 2005) and
therefore was considerably influenced by the strong Japanese equity market rally
that took place. Several of the key performance "positives" for the Fund
included:

     o    Retailing  investments - Yamada Denki,  a Japanese home  appliance and
          consumer electronics manufacturer, had a return of 121%. (2)

     o    Semiconductor-related holdings - Samsung Electronics rose 44%.

     o    Energy - We were  fortunate to  experience  good results in several of
          our energy-related  holdings. These included Talisman Energy (+91%), a
          Canadian-headquartered    company   that   explores,   develops,   and
          distributes  crude oil,  natural  gas,  and  natural  gas liquids in a
          variety of markets.  Brazilian-based oil company Petroleos  Brasileiro
          SA (+52%) also had a strong return.

     o    Telecommunications Services - America Movil SA, a provider of wireless
          communications services in Latin America, gained nearly 104%.

     o    Banks - The Fund's  banking-related  holdings had a good year and were
          among its top-performing  individual holdings. These included Japanese
          banks Mitsubishi Ufj (+59%) and Sumitomo Mitsui (+42%).  ICICI Bank, a
          full service  banking  company in India,  and Erste Bank der Oster, an
          Austria-based private and commercial banking organization, had returns
          of 108% and 31%, respectively.



MARSICO INTERNATIONAL OPPORTUNITIES FUND


     o    Real Estate - Singapore-based  property  services provider  CapitaLand
          Ltd.  (+79%) and  Leopalace 21 Corp.  (+34%),  a Japanese  residential
          building firm, were solid performing holdings.

     o    Utilities - British  Energy,  a recently  restructured  nuclear  power
          company, gained 73%.

     o    Country  Allocations  - The Fund had a number  of equity  holdings  in
          markets not  included  in the EAFE Index that  performed  well.  These
          included certain holdings in Canada,  Mexico, Brazil, India, and South
          Korea.

A few factors caused the Fund's one-year return to slightly trail the EAFE
Index. One factor related to the Fund's posture in the Consumer Discretionary
sector. Throughout the past year, the Fund tended to have a high degree of
emphasis on this sector, which at times meant that the Fund was almost
double-weighted in this sector as compared to the EAFE Index. The Fund's
positions in Consumer Discretionary sector were allocated across a variety of
industries and individual companies and had a collective price return of 18% for
the Fund. That was a good absolute return and it included some good stock
selection, particularly in the retailing industry. In addition, Shangri-La Asia,
a Hong Kong-based hotel operator, and Grupo Televisa SA, a Mexico
City-headquartered provider of television broadcasting services, had strong
returns of 53% and 42%, respectively, while held in the Fund. However, the
Fund's overall return in this sector trailed the benchmark index return by
almost 8%. The Fund's media-related holdings had an aggregate return of about
11% over the fiscal year - well behind the EAFE Index's overall gain for the
one-year period ended September 30, 2005. Thomson SA, a video service provider
to the entertainment and media industries, fell by 24% and some of the Fund's
hotel/casino operator positions (e.g., Kerzner International, Wynn Resorts) were
among the Fund's performing holdings and weighed on the Fund's overall sector
return. The impact of that performance shortfall was magnified by our decision
to have such an emphasis on this sector.

Another "soft spot" for the Fund's performance related to its over-weighted
posture in the Information Technology sector, which, as mentioned earlier, was
(somewhat remarkably) the lowest-returning sector in the EAFE Index for the
one-year period ended September 30, 2005. That created an opportunity cost of
sorts, as there were quite a few other areas of the market that had considerably
better returns. The Fund's Information Technology holdings gained 14% in
aggregate, with Samsung Electronics (+44%) among the top-performing individual
holdings. However, that result - in the context of a benchmark index that rose
nearly 26% - did not help the Fund's overall return.

The Fund's positions in the Financials sector had somewhat mixed returns last
year. A variety of banking positions were strong performers, as mentioned above.
Offsetting those gains to a significant extent were the Fund's insurance
positions, including Swiss Life Holding (-8% prior to being sold). Promise Co.,
a Japanese consumer finance company providing unsecured and non-guaranteed
loans, fell -13% prior to being sold. Takefuji, another Japanese consumer
finance company, declined by -17% prior to being sold.

The Fund's cash positions, which typically are a residual of our stock selection
process, mildly impacted performance results. This was particularly true in the
fourth calendar quarter of 2004, when international equities generally
experienced substantial gains and the Fund's modest cash positions impacted
performance. The trend of international equities outperforming cash by a wide
margin continued through the end of the Fund's 2005 fiscal year. For this
reason, any cash positions held during the past year tended to create a modest
"drag" on performance.



For the complete fiscal year, fluctuations in currency
exchange rates did not have a material impact on the Fund's return. At times
during the year, however, currency was a significant factor. In the fourth
quarter of 2004, for example, the Fund had a number of US dollar-related
positions, which included some positions that trade in dollars or were
denominated in a currency that tends to correlate highly with the US dollar
(e.g., the Mexican peso). As the dollar weakened in relation to other major
world currencies, the Fund's performance was adversely impacted. Later in the
fiscal year, however, the dollar rallied considerably, which helped the Fund's
dollar-related positions.

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.

FISCAL YEAR-END INVESTMENT POSTURE

As of September 30, 2005 the Fund's holdings, in terms of economic sector
distribution, were allocated primarily to Consumer Discretionary, Financials,
Health Care, Information Technology, and Industrials. The Fund's largest
country-level allocations were in Japan, the United Kingdom, Switzerland,
France, and Canada.

MARSICO FUNDS

NOTES TO FINANCIAL STATEMENTS SEPTEMBER 30, 2005


 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 7% of the 21st Century
   Fund and 9% 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 Funds' Board of Trustees. The Funds may use pricing
       services to assist in determining 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 $1,034,961 and
       $311,115 for the Focus Fund and Growth Fund, respectively, for the year
       ended September 30, 2005. Also, the Funds received credits on certain
       custody account balances which reduced certain transfer agent fees and
       expenses in the amount of $10,524, $5,611, $1,101 and $594 for the Focus
       Fund, Growth Fund, 21st Century Fund and International Opportunities
       Fund, respectively, for the year ended September 30, 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. Accordingly, at September 30, 2005,
       reclassifications (in thousands) were recorded to increase (decrease)
       paid-in-capital by $(7,803), $(2,712), $(225) and $12, increase
       (decrease) net investment income by $6,990, $2,415, $1,009 and $(134) and
       increase (decrease) accumulated net realized gain (loss) on investments
       and foreign currency transactions by $813, $297, $(784) and $122 for the
       Focus, Growth, 21st Century and International Opportunities Funds,
       respectively.

   (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.



MARSICO FUNDS

NOTES TO FINANCIAL STATEMENTS SEPTEMBER 30, 2005 (continued)

   (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
       counter-party 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.

   Transactions in call options written for the year ended September 30, 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 $115,840,
       $54,302, $31,531 and $27,377 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 year ended September 30, 2005, the Focus
       Fund, Growth Fund, 21st Century Fund and International Opportunites Fund
       received $28,928, $84,502, $35,265 and $10,750, 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.

   (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. 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
   year ended September 30, 2005, the Adviser recovered previously waived fees
   of $98,548 and $203,223, respectively, in the 21st Century Fund and
   International Opportunities Fund.

   As of September 30, 2005, the reimbursement that may potentially be made by
   the International Opportunities Fund to the Adviser is $101,347, which
   expires between 2006 and 2007.

   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 year ended September 30, 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.

 6.FEDERAL INCOME TAX INFORMATION

   At September 30, 2005, gross unrealized appreciation and depreciation of
   investments, based on cost for federal income tax purposes were as follows:
                                                                                             21st            International

   (Amounts in thousands)                          Fund                  Fund                Fund                Fund
- --------------------------------------------------------------------------------------------------------------------------------

   Cost of investments                          $2,776,966           $1,710,168            $326,139            $226,990

   Gross unrealized appreciation                 1,037,772              497,007              63,170              43,477
   Gross unrealized depreciation                   (77,800)             (32,614)             (8,615)             (5,077)
                                             -----------------------------------------------------------------------------------
   Net unrealized appreciation on investments     $959,972             $464,393             $54,555             $38,400



   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, and International Opportunities Funds had realized
   currency losses (in thousands) from transactions between November 1, 2004 and
   September 30, 2005 of $76, $15, and $125, respectively. Post-October currency
   losses and capital losses are treated as arising in the Funds' next fiscal
   year.

   At September 30, 2005, the Focus, Growth, 21st Century and International
   Opportunities Funds had accumulated capital loss carryforwards (in thousands)
   of $173,667, $118,864, $36,559 and $1,519, with $0, $0, $8,036 and $0
   expiring in 2009, $86,197, $40,272, $28,523 and $1,441 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 (in thousands) $119,576, $14,183, $14,115 and $4,326, respectively,
   of its capital loss carryforwards during the year ended September 30, 2005.

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

   As of September 30, 2005, the components of accumulated  earnings (deficit)
   on a tax basis were as follows:

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of The Marsico Investment Fund

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the Marsico Focus Fund, the Marsico
Growth Fund, the Marsico 21st Century Fund and the Marsico International
Opportunities Fund (constituting The Marsico Investment Fund, hereafter referred
to as the "Trust") at September 30, 2005, the results of each of their
operations for the year then ended, the changes in each of their net assets for
each of the two years in the period then ended and the financial highlights for
each of the five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Trust's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with the standards of the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at September 30, 2005 by
correspondence with the custodian and brokers and the application of alternative
auditing procedures where securities purchased had not been received, provide a
reasonable basis for the opinion expressed above.

MARSICO FUNDS

EXPENSE EXAMPLE FOR THE SIX MONTHS ENDED SEPTEMBER 30, 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 April 1, 2005 to September 30, 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.

(e) (1) Audit Committee Pre-Approval Policies and Procedures:


Pursuant to the Trust's Audit Committee Charter and Policies and Procedures
(collectively, the "Procedures"), the Audit Committee has adopted pre-approval
policies and procedures to govern the pre-approval of (i) all audit services and
permissible non-audit services to be provided to the Trust by its independent
accountant, and (ii) all permissible non-audit services to be provided by such
independent accountant to the Trust's investment adviser and to any entity
controlling, controlled by or under common control with the investment adviser
that provides on-going services to the Trust (collectively, any "Service
Affiliates") if the engagement directly relates to the Trust's operations and
financial reporting.

In accordance with the Procedures, the Committee is responsible for the
engagement of the independent accountant to certify the Trust's financial
statements for each fiscal year. With respect to the pre-approval of non-audit
services provided to the Trust and its Service Affiliates, the Procedures
provide that the Committee may pre-approve such services on a project-by-project
basis as they arise. The Procedures also permit the Committee to delegate
authority to the Audit Committee Chairman (the "Designated Member") to
pre-approve any proposed non-audit services that have not been previously
approved by the Committee, subject to certain conditions. Any action by the
Designated Member in approving a requested non-audit service shall be presented
to the Audit Committee not later than at its next scheduled meeting. If the
Designated Member does not approve the independent auditor's provision of a
requested non-audit service, the matter may be presented to the full Committee
for its consideration and action.

Regulation S-X:

100% of these fees were approved by the Trust's Audit Committee as required
pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X.

(g) In each of the fiscal years ended September 30, 2005 and September 30, 2004,
the aggregate fees billed (or to be billed) by PwC relating to non-audit
