                             LETTER TO SHAREHOLDERS

        As we now approach the fifth anniversary of the stock market's March
2000 peak, it may be instructive to look at how investors have fared in the
subsequent years. Two observations stand out.

        First, just as the speculative boom that led up to the market peak was
very uneven, with some stocks participating to a far greater degree than others,
the post-bubble market has also had its winners and losers. Generally, small and
non-tech stocks, which missed much of the 1990s' party, have done well,
especially relative to the negative performance for the market as a whole.

        Second, although we are all familiar with long-term studies which show
that equity markets have delivered quite attractive returns over virtually all
long time periods, it turns out that purchasing shares of even the best
companies at bubble highs is unlikely to EVER deliver adequate rates of return.
For example, investors who purchased Microsoft, Intel, and Cisco, each large and
highly successful businesses, in March 2000, have now lost about two thirds of
their funds, or 20% annually over the subsequent five-year period. In other
words, they have suffered a substantial and permanent loss of capital.

        Perennial has approached the market environment of the past five years
no differently than prior periods. We have striven to own high-quality
businesses, but have refused to overpay for them. Though this has produced past
periods of underperformance when overpriced stocks became even more overpriced,
on balance it has served the Perennial shareholder well.

        The following table shows returns for one-, three-, and five-year
periods for the leading large- and small-cap averages, as well as for Perennial.

        We were frankly surprised at how strongly the market performed in 2004,
especially after the large advance of 2003. Most indexes were up between 10% and
20%, with small-cap stocks repeating their leadership performance of 2003. The
Russell 2000, for example, is up about 75% over the past two years, and has
nearly doubled from its March 2003 lows.

        Perennial's 16.3% gain in 2004 fell a bit short of the benchmark Russell
2500. Higher cash levels, driven by caution about stock valuations, was the
primary cause of the difference. The table below shows Perennial's returns for
each year since 2000, as well as those of the Russell 2500.

        We would like to discuss a recent addition to Perennial's portfolio.
Founded in 1917 as a pioneer in the development of all-wheel drive technology,
OSHKOSH TRUCK has spent most of its existence as a builder of military trucks.
Under new management, Oshkosh reinvented itself in the mid-1990s. Starting with
a business that was two thirds defense products, Oshkosh aggressively
diversified. With a series of acquisitions, it entered related specialty truck
areas, buying either the market leader, or more often, the strong number two
company in the industry. It improved manufacturing and invested in product
development and technology. Over time, almost all of these acquired businesses
have gained the number one share position as well as improved profitability.
Sales have increased from $400 million in 1996 to over $2 billion today.

        As it expanded the scope of its business, Oshkosh took on large amounts
of debt, but its strong cash flow has enabled it to considerably reduce leverage
in recent years - from debt at 65% of capital five years ago to just 15% today.
Returns on capital have been excellent and trending upwards. Return on equity
over the past five years has averaged 20%.

                                        1

        Oshkosh's largest business is defense, where it supplies medium and
heavy trucks to the U.S. and U.K. military. Though somewhat lumpy, with a small
number of very large contracts, it has the advantage of large backlogs and
long-lived procurements, as well as a continuing demand for parts and
reconditioning. Oshkosh is the market share leader, well ahead of rival Stewart
and Stevenson, with projected Year 2005 sales of about $1 billion, 35% of the
corporate total. Oshkosh's defense operations are currently especially busy
because of the severe wear on vehicles operating in Iraq and Afghanistan.

        Oshkosh entered the fire-truck and emergency-vehicle business in 1996,
acquiring Pierce Manufacturing, the number two company in the industry, behind
Federal Signal's E-One. Current Pierce sales are about $700 million, or one
quarter of total Oshkosh revenues. It has grown to the leading market share
spot, with about 30% of the U.S. market, helped both by its own product
innovations and by missteps of E-One.

        Oshkosh entered the cement mixer market in 1998 with its purchase of
McNeilus Companies. With a 65% share, McNeilus was already by far the market
leader, however, Oshkosh has further grown its share to about 75%. Current sales
are $550 million, or 20% of Oshkosh's total. It has recently introduced a
revolutionary new product - a cement truck with a plastic composite drum
replacing the usual steel drum. Because the drum is 2,000 pounds lighter, the
new trucks can carry an extra ton of cement, significantly reducing
transportation costs per unit delivered. Oshkosh has recently started to
aggressively market this exciting new product to its cement-mixer customers.

        Oshkosh also makes refuse truck bodies, a business it entered by
acquisition in 1998 in the U.S. (McNeilus) and 2001 in Europe (Geesink Norba).
At the time it was a distant number two, with barely half the 32% market share
of leader Heil (owned by Dover). It has now completely closed that gap and is
tied for the number one spot with Heil, at about 25% each, having successfully
executed a strategy of focusing on the Big 3 private haulers. With total sales
of $400 million, refuse trucks represent 15% of Oshkosh revenues.

        Oshkosh's most recent business is tow trucks and wreckers, which it
entered in June 2004, with the purchase of Jerr-Dan. With sales of $100 million,
Jerr-Dan is half the size of market leader Miller, but has some innovative
technology that Oshkosh plans to further develop.

        We purchased most of our Oshkosh Truck position during the middle of
last year at about $50 per share, 16x year 2004 earnings. We believe that the
share price was under pressure because of some nagging concerns about the
business, including difficulty in recovering steel cost increases, a large U.K.
military truck contract not awarded to Oshkosh, and manufacturing issues at
Geesink Norba and with the new cement-truck drum.

        After a recent strong December quarter earnings report, the Street
appears to be feeling better about most of these issues, and the stock is
trading at about $70 per share or 17-18x estimated 2005 earnings. We are
comfortable with our 2.5% position and hope to own Oshkosh Truck for many years.

Past performance is not indicative of future performance. The Russell 2500 Index
consists of the 2,500 smallest companies in the Russell 3000 total
capitalization universe. This index is considered a measure of small to medium
capitalization stock performance. This index does not reflect any commissions or
fees which would be incurred by an investor purchasing the stocks it represents.
The Lipper Mid-Cap Core Fund Average provides an additional comparison of how
your Fund performed in relation to other mutual funds with similar objectives.
The Lipper data does not include sales charges. The performance shown for FPA
Perennial Fund, Inc., with an ending value of $42,316 reflects deduction of the
current maximum sales charge of 5.25% of the offering price. In addition, since
investors purchase shares of the Fund with varying sales charges depending
primarily on volume purchased, the Fund's performance at net asset value (NAV)
is also shown, as reflected by the ending value of $44,661. The performance of
the Fund and of the Averages is computed on a total return basis which includes
reinvestment of all distributions.

                          NOTES TO FINANCIAL STATEMENTS
                                December 31, 2004

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES

     FPA Perennial Fund, Inc. (the "Fund") is registered under the Investment
Company Act of 1940 as a diversified, open-end, management investment company.
The Fund's primary investment objective is long-term growth of capital. Current
income is a secondary consideration. The following is a summary of significant
accounting policies consistently followed by the Fund in the preparation of its
financial statements.

A.   Security Valuation

         Securities listed or traded on a national securities exchange are
     valued at the last sale price. Securities traded on the NASDAQ National
     Market System are valued at the NASDAQ Official Closing Price. If there was
     not a sale that day, these securities are valued at the last bid price.
     Securities which are unlisted are valued at the most recent bid price.
     Short-term investments with maturities of 60 days or less are valued at
     amortized cost which approximates market value.

B.   Federal Income Tax

         No provision for federal income tax is required because the Fund has
     elected to be taxed as a "regulated investment company" under the Internal
     Revenue Code and intends to maintain this qualification and to distribute
     each year to its shareholders, in accordance with the minimum distribution
     requirements of the Code, all of its taxable net investment income and
     taxable net realized gains on investments.

C.   Securities Transactions and Related Investment Income

         Securities transactions are accounted for on the date the securities
     are purchased or sold. Dividend income and distributions to shareholders
     are recorded on the ex-dividend date. Interest income and expenses are
     recorded on an accrual basis.

D.   Use of Estimates

         The preparation of the financial statements in accordance with
     accounting principles generally accepted in the United States requires
     management to make estimates and assumptions that affect the amounts
     reported. Actual results could differ from those estimates.

E.   Reclassification of Capital Accounts

         As of December 31, 2004, $140,518 of accumulated net losses were
     reclassified to undistributed net realized gains on investments in order to
     adjust for differences between income tax regulations and accounting
     principles generally accepted in the United States.

NOTE 2 -- PURCHASES AND TAX DIFFERENCES

     The cost of purchases of investment securities (excluding short-term
investments with maturities of 60 days or less) aggregated $85,163,702 for the
year ended December 31, 2004. Realized gains or losses are based on the specific
identification method.

     All of the amounts reported in the financial statements at December 31,
2004 were the same for federal income tax and financial reporting purposes.
Gross unrealized appreciation for all investments at December 31, 2004 for
federal income tax and financial reporting purposes was $65,777,674.

     The distribution paid on December 23, 2004 was characterized as long-term
capital gains for federal income tax purposes.

NOTE 3 -- ADVISORY FEES AND OTHER AFFILIATED TRANSACTIONS

     Pursuant to an Investment Advisory Agreement, advisory fees were paid by
the Fund to First Pacific Advisors, Inc. (the "Adviser"). Under the terms of
this Agreement, the Fund pays the Adviser a monthly fee calculated at the annual
rate of 0.75% of the first $50 million of the Fund's average daily net assets
and 0.65% of the average daily net assets in excess of $50 million. In addition,
the Fund pays the Adviser an amount equal to 0.10% of the average daily net
assets for each fiscal year in reimbursement for the provision of financial
services to the Fund. The Agreement obligates the Adviser to reduce its fee to
the extent necessary to reimburse the Fund for any annual expenses (exclusive of
interest, taxes, the cost of any supplemental statistical and research
information, and extraordinary expenses such as litigation) in excess of 1 1/2%
of the first $30 million and 1% of the remaining average net assets of the Fund
for the year.

                                       11
<Page>

     For the year ended December 31, 2004, the Fund paid aggregate fees of
$19,000 to all Directors who are not affiliated persons of the Adviser. Legal
fees were for services rendered by O'Melveny & Myers LLP, counsel for the Fund.
A Director of the Fund is a retired partner of that firm. Certain officers of
the Fund are also officers of the Adviser and FPA Fund Distributors, Inc.

NOTE 4 -- REDEMPTION FEE

     A redemption fee of 2% applies to redemptions within 90 days of purchase
for certain purchases made by persons eligible to purchase shares without an
initial sales charge. For the year ended December 31, 2004, the Fund collected
$7,505 in redemption fees. The impact of these fees is less than $0.01 per
share.

NOTE 5 -- DISTRIBUTOR

     For the year ended December 31, 2004, FPA Fund Distributors, Inc.
("Distributor"), wholly owned subsidiary of the Adviser, received $114,779 in
net Fund share sales commissions after reallowance to other dealers. The
Distributor pays its own overhead and general administrative expenses, the cost
of supplemental sales literature, promotion and advertising.

                        REPORT OF INDEPENDENT REGISTERED
                             PUBLIC ACCOUNTING FIRM

TO THE SHAREHOLDERS AND
BOARD OF DIRECTORS OF FPA PERENNIAL FUND, INC.

     We have audited the accompanying statement of assets and liabilities of FPA
Perennial Fund, Inc. (the "Fund"), including the portfolio of investments, as of
December 31, 2004 and the related statement of operations for the year then
ended, and the statements of changes in net assets for each of the two years in
the period then ended, and the financial highlights for each of the three years
in the period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights of FPA Perennial Fund, Inc. for each of
the two years in the period ended December 31, 2001 were audited by other
auditors whose report, dated February 1, 2002, expressed an unqualified opinion
on those financial highlights.

     We conducted our audits in accordance with 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 and financial highlights are free of material misstatement. An audit
includes consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the Fund's
internal control over financial reporting. Accordingly, we express no such
opinion. An audit also 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, as well
as evaluating the overall financial statement presentation. Our procedures
included confirmation of securities owned as of December 31, 2004, by
correspondence with the custodian. We believe that our audits provide a
reasonable basis for our opinion.

     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of FPA
Perennial Fund, Inc. as of December 31, 2004, the results of its operations for
the year then ended and the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for each of the three
years in the period then ended in conformity with accounting principles
generally accepted in the United States of America.

                           SHAREHOLDER EXPENSE EXAMPLE
                                December 31, 2004
                                   (unaudited)

FUND EXPENSES

     As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, and (2) ongoing costs, including advisory and administrative fees;
shareholder service fees; and other Fund expenses. The Example is intended to
help you understand your ongoing costs (in dollars) of investing in the Fund and
to compare these costs with the ongoing costs of investing in other mutual
funds. The Example is based on an investment of $1,000 invested at the beginning
of the year and held for the entire year.

ACTUAL EXPENSES

     The information in the table under the heading "Actual Performance"
provides information about actual account values and actual expenses. You may
use the information in this column, together with the amount you invested, to
estimate the expenses that you paid over the period. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000= 8.6),
then multiply the result by the number in the first column in the row entitled
"Expenses Paid During Period" to estimate the expenses you paid on your account
during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

     The information in the table under the heading "Hypothetical Performance
(5% return before expenses)" provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Fund's
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of other funds.

     Please note that the expenses shown in the table are meant to highlight
your ongoing costs only and do not reflect any transactional costs. Therefore,
the information under the heading "Hypothetical Performance (5% return before
expenses)" is useful in comparing ongoing costs only, and will not help you
determine the relative total costs of owning different funds. In addition, if
these transactional costs were included, your costs would have been higher.

          (a)     The registrant has adopted a code of ethics that applies to
                  the registrant's senior executive and financial officers. Upon
                  request, any person may obtain a copy of this code of ethics,
                  without charge, by calling (800) 982-4372. A copy of the code
                  of ethics is filed as an exhibit to this Form N-CSR.

                  amendments to the provisions of the code of ethics adopted in
                  2(a) above.

</Table>

          (e)(1)  Disclose the audit committee's pre-approval policies and
                  procedures described in paragraph (c)(7) of Rule 2-01 of
                  Regulation S-X. The audit committee shall pre-approve all
                  audit and permissible non-audit services that the committee
                  considers compatible with maintaining the independent
                  auditors' independence. The pre-approval requirement will
                  extend to all non-audit services provided to the registrant,
                  the adviser, and any entity controlling, controlled by, or
                  under common control with the adviser that provides ongoing
                  services to the registrant, if the engagement relates directly
                  to the operations and financial reporting of the registrant;
                  provided, however, that an engagement of the registrant's
                  independent auditors to perform attest services for the
                  registrant, the adviser or its affiliates required by
                  generally accepted auditing standards to complete the
                  examination of the registrant's financial statements (such as
                  an examination conducted in accordance with Statement on
                  Auditing Standards Number 70 issued by the American Institute
                  of Certified Public Accountants), will be deem pre-approved
                  if: (i) the registrant's independent auditors inform the audit
                  committee of the engagement, (ii) the

<Page>

                  registrant's independent auditors advise the audit committee
                  at least annually that the performance of this engagement will
                  not impair the independent auditor's independence with respect
                  to the registrant, and (iii) the audit committee receives a
                  copy of the independent auditor's report prepared in
                  connection with such services. The committee may delegate to
                  one or more committee members the authority to review and
                  pre-approve audit and permissible non-audit services. Actions
                  taken under any such delegation will be reported to the full
                  committee at its next meeting.

          (e)(2)  Disclose the percentage of services described in each of
                  paragraphs (b) - (d) of this Item that were approved by the
                  audit committee pursuant to paragraph (c)(7)(i)(C) of Rule
                  2-01 of Regulation S-X. 100% of the services provided to the
                  registrant described in paragraphs (b) - (d) of this Item were
                  pre-approved by the audit committee pursuant to paragraphs
                  (e)(1) of this Item. There were no services provided to the
                  investment adviser or any entity controlling, controlled by or
                  under common control with the adviser described in paragraphs
                  (b) - (d) of this Item that were required to be pre-approved
                  by the audit committee.

          (f)     If greater than 50%, disclose the percentage of hours expended
                  on the principal accountant's engagement to audit the
                  registrant's financial statements for the most recent fiscal
                  year that were attributed to work performed by persons other
                  than the principal accountant's full-time, permanent
                  employees. All services performed on the engagement to audit
                  the registrant's financial statements for the most recent
                  fiscal year end were performed by the principal accountant's
                  full-time, permanent employees.

          (g)     Disclose the aggregate non-audit fees billed by the
                  registrant's accountant for services rendered to the
                  registrant, and rendered to the registrant's investment
                  adviser (not including any sub-adviser whose role is primarily
                  portfolio management and is subcontracted with or overseen by
                  another investment adviser), and any entity controlling,
                  controlled by, or under common control with the adviser that
                  provides ongoing services to the registrant for each of the
                  last two fiscal years of the registrant. None.

          (h)     Disclose whether the registrant's audit committee of the board
                  of director has considered whether the provision of non-audit
                  services that were rendered to the registrant's investment
                  adviser (not including any sub-adviser whose role is primarily
                  portfolio management and is subcontracted with or overseen by
                  another investment adviser), and any entity controlling,
                  controlled by, or under common control with the investment
                  adviser that provides ongoing services to the registrant that
                  were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule
                  2-01 of Regulation S-X is

          Not Applicable.

Item 9.   Purchases of Equity Securities by Closed-End Management Investment

Item 10.  Submission of Matters to a Vote of Security Holders. There has been no
          material change to the procedures by which shareholders may recommend
          nominees to the registrant's board of directors.

Item 11.  Controls and Procedures.

          (a)     The Principal Executive Officer and Principal Financial
                  Officer of the registrant have concluded that the registrant's
                  disclosure controls and procedures (as defined in Rule
                  30a-3(c) under the Investment Company Act of 1940) are
                  effective based on their evaluation of the disclosure controls
                  and procedures as of a date within 90 days of the filing date
                  of this report.

          (b)     There have been no significant changes in the registrant's
                  internal controls over financial reporting (as defined in Rule
                  30a-3(d) under the Investment Company Act of 1940) that
                  occurred during the registrant's last fiscal half-year (the
                  registrant's second fiscal half- year in the case of an annual
                  report) that has materially affected, or is reasonably likely
                  to materially affect, the registrant's internal controls over
                  financial reporting.

Item 12.  Exhibits.
