COMMENTARY(1)

                                                               December 31, 2003

OVERVIEW

The Fund generated a return of 14.79% for the fourth quarter, compared to a
16.37% gain for the Russell 2000 Value Index and a 14.52% gain for the Russell
2000 Index. For all of 2003, the Fund rose 40.71%, versus a 46.03% gain for the
Russell 2000 Value Index and a 47.25% rise for the Russell 2000 Index. The
40.71% return for 2003 marked the third largest calendar-year gain for the Fund
since its inception. The returns generated by the Russell small cap Indexes were
the largest on record.

The outstanding returns generated by small cap stocks in the fourth quarter and
for all of 2003 were due in part to increased earnings. The stocks that made up
the Fund at year end are estimated to have grown their median 2003 earnings per
share (EPS) by 10.6%. We believe a more important contributor to 2003's stock
price gains was an improvement in investor sentiment. The uncertainties (Iraq,
terrorism, SARS, corporate scandals) that abounded in early 2003 failed to
derail the U.S. economy. On the contrary, economic reports grew increasingly
positive as the year progressed. Bolstered by a more favorable outlook,
investors placed higher valuations on stocks.

In both the fourth quarter and for all of 2003, the gains generated by the Fund
lagged the returns posted by the Russell 2000 Value Index. This was due
primarily to the higher proportion of smaller and riskier stocks in the Index,
which were among the best performing stocks for both the quarter and year. We
define riskier stocks as those with no earnings and/or high financial leverage.

MARKET REVIEW

Stock gains were broad based during the fourth quarter, with all of the major
style indexes posting double-digit gains. Small cap stocks outperformed large
cap stocks in the quarter, as indicated by the 14.52% gain for the Russell 2000
Index versus the 12.18% rise for the S&P 500 Index. Within the small cap arena,
the Russell 2000 Value Index's 16.37% gain outpaced the 12.68% rise for the
Russell 2000 Growth Index. The best performing economic sectors in the Russell
2000 Value Index during the quarter were other energy, materials and processing,
and producer durables, all rising more than 20%. Companies in these sectors are
impacted by manufacturing activity, and several reports released during the
quarter pointed to improvement in that area of the economy. For example, the
widely followed Manufacturing ISM Report on Business reported in December that
manufacturing activity rose for the fifth consecutive month in November to its
highest level since December 1983. The utilities, financial services, consumer
discretionary, and health care sectors, which are less tied to manufacturing
activity, despite posting double-digit gains, lagged the Russell 2000 Value
Index's total return for the quarter.

                                        1
<Page>

For the year, small cap stocks, as measured by the Russell 2000 Index, rose
47.25%, outpacing the 28.71% gain registered by the S&P 500 Index. It was the
fourth consecutive year that small cap stocks outperformed large cap stocks.
Among small caps, the Russell 2000 Value Index rose 46.03% and the Russell 2000
Growth Index was up 48.54%, marking the first year since 1999 that small cap
growth stocks outperformed small cap value stocks. The smallest and riskiest
stocks were the best performers in 2003. According to Prudential Financial,
within the Russell 2000 Index, the stocks with market caps under $500 million
were up 59.5%, stocks not expected to earn money over the next 12 months were up
72% for the year, and stocks with prices below $5 increased 114%. Strong
relative performance by smaller and riskier stocks often occurs during the early
stages of an economic rebound, similar to the one we believe we are currently
experiencing.

PORTFOLIO REVIEW

As previously noted, the Fund posted a gain of 14.79% for the fourth quarter and
40.71% for all of 2003. This compares to gains of 16.37% and 46.03% for the
Russell 2000 Value Index and 14.52% and 47.25% for the Russell 2000 Index for
the fourth quarter and all of 2003, respectively.

For the fourth quarter, the materials and processing, consumer discretionary,
financial services, and technology sectors contributed most to the Fund's
return. The materials and processing and technology sectors benefited from
strong price performance. Six of the ten stocks that contributed most to the
Fund's return for the quarter came from these two sectors. The contribution from
the consumer discretionary and financial sectors was due primarily to the heavy
weighting of those sectors in the Fund. Compared to the benchmark, the
technology sector contributed most during the quarter, due to its relatively
heavy weighting and strong stock selection. The financial services sector, which
included four of the ten poorest performing stocks during the quarter, was the
largest detractor to the Fund's performance relative to the benchmark.

For the year, the consumer discretionary and financial services sectors
contributed the most to the return of the Fund, due to their high absolute
weightings and returns. Seven of the top ten best performing stocks were from
these two sectors. For the most part, the sectors of the Fund performed roughly
in line with the corresponding sectors of the benchmark. The exceptions were the
autos and transportation, other energy, and health care sectors, which lagged
the respective sectors of the benchmark. The returns for the other energy and
health care sectors of the Index benefited disproportionately from the strong
performance of smaller and riskier stocks during the year.

In certain instances, the Fund benefited from the strong performance of smaller
and riskier stocks during the year. Graftech International, Ltd. and Fairchild
Semiconductor International, Inc. are examples of stocks that, at the time of
purchase, were generating very low levels of earnings (but inexpensive on other
measures of value) and performed extremely well in 2003 as investors became more
confident in their outlooks. However, the bulk of the Fund's performance in 2003
was driven by stocks that were inexpensive on current earnings at the beginning
of the year or at the time

                                        2

of purchase, and that responded positively to improving fundamentals. Examples
of the types of stocks that were significant contributors to the Fund's
performance in 2003 are Michaels Stores Inc., Ruby Tuesday Inc., and iStar
Financial Inc.

OUTLOOK

We believe statistics reported over the last several months point to a positive
outlook for the U.S. economy and corporate profits. The employment situation
appears to be improving -- payroll jobs were up in each of the last four months
of 2003, and initial claims for unemployment insurance have been trending lower.
The long U.S. manufacturing recession appears to be coming to an end, as
indicated by the previously mentioned Manufacturing ISM report. Massive fiscal
(higher government spending on defense, tax cuts, and accelerated depreciation
allowances) and monetary (a Fed Funds rate of 1.0%) stimulus has been applied by
government authorities. Importantly, in its December 9, 2003 statement, the
Federal Open Market Committee stated,"...with inflation quite low and resource
use slack, the Committee believes that policy accommodation can be maintained
for a considerable period." The U.S. dollar declined almost 15% against a basket
of major currencies in 2003, which should improve the competitiveness of U.S.
companies in global markets. Companies are well positioned to finance capital
expansion projects. In aggregate, companies are now generating more cash flow
from operations than they are committing to capital expenditures. Those
companies that require outside funding are able to raise capital at attractive
rates due to low interest rates, tighter credit spreads, and an accommodating
equity market.

The improving outlook for corporate profits has not gone unnoticed by investors.
The record setting performance registered by small cap stocks during 2003 has
driven the Russell 2000 Index's price/earnings (excluding negative earnings) of
14.0x at the end of the first quarter to 20.4x at year end. At current
valuations, it is difficult to make a strong case for a significant expansion in
price earnings multiples. Therefore, it is our belief that further gains in
stock prices will be a function of the growth in earnings. As previously
mentioned, we are quite optimistic about the outlook for corporate profits, and
therefore for the outlook for stock prices, but without significant multiple
expansion, gains approaching 2003 levels are unlikely.

The rise in stock prices and an improved economic outlook have combined to alter
the risk/reward equation for investors. Valuations are no longer at levels to
provide a margin of safety to investors if earnings are disappointing. However,
we believe there is more evidence supporting the case for strong earnings than
there has been in some time. If earnings come through as or better than
expected, as we anticipate they will, stocks should respond positively.

STOCK HIGHLIGHTS(3)

DELPHI FINANCIAL GROUP INC. (DFG)

Delphi Financial Group, Inc. is an employee benefit services company. DFG
provides group life insurance, long-term and short-term disability insurance,
excess workers' compensation insurance, and fixed annuities. The excess workers'
compensation business is the driving force behind higher overall levels of
profitability and earnings growth. The excess workers' compensation business is
benefiting from several trends. Corporations are faced with significant
increases in employee benefits costs and many are choosing to self-insure as a
method of controlling the costs. When companies self-insure workers'
compensation, they will purchase excess workers' compensation from DFG to insure
against any catastrophic losses. In addition, there are very few competitors
offering similar products, therefore the current strong demand is creating a
positive pricing environment for DFG. The stock sells at a low P/E and is
expected to grow earnings in excess of 12% per year over the next several years.

IKON OFFICE SOLUTIONS, INC. (IKN)

Ikon Office Solutions, Inc. is one of the largest distributors of copiers in the
U.S. and Europe. IKN should generate strong EPS growth over the next few years
due to the following three factors: IKN will likely benefit from the
implementation of a new enterprise-wide operating system which will allow for a
material reduction in staffing; IKN is selling its leasing business to GE
Capital which will generate significant proceeds to reduce debt and repurchase
shares; and an improving economy will increase sales of new equipment. IKN is a
very cheap stock trading at a mid-teens P/E multiple on trailing earnings with
the ability to generate strong EPS growth over the next three to five years.

There are risks of investing in a fund that invests in stocks of small sized
companies, which tend to be more volatile and less liquid than stocks of large
cap companies. There are also risks in investing in value-oriented stocks
including the risk that value-oriented stocks will underperform growth-oriented
stocks during some periods.

VIEWS OF SKYLINE ASSET MANAGEMENT, L.P., THE FUND'S ADVISER, AT THE TIME OF THIS
REPORT. THE INVESTMENTS OF THE FUND ARE SUBJECT TO CHANGE AND SHOULD NOT BE
CONSIDERED A RECOMMENDATION TO BUY INDIVIDUAL SECURITIES.

(a)  Non-income producing security.

Based on cost of investments for federal income tax purposes of $399,973,685 on
December 31, 2003, net unrealized appreciation was $124,069,522, consisting of
gross unrealized appreciation of $126,801,010 and gross unrealized depreciation
of $2,732,488.

The differences between book-basis and tax-basis unrealized
appreciation/(depreciation) is attributable primarily to the estimated tax
deferral on wash sales and return of capital distributions received from
investments in real estate investment trusts.

NOTES TO FINANCIAL STATEMENTS

Skyline Funds is an open-end, diversified investment management company the sole
portfolio of which is Special Equities Portfolio (the "Fund"). The Fund
commenced public offering of its shares on April 23, 1987. Skyline Special
Equities Portfolio closed to new investors on January 30, 1997 and re-opened to
new investors on October 27, 1999. The Fund's investment adviser is Skyline
Asset Management, L.P. ("The Adviser"). The Fund seeks maximum capital
appreciation primarily through investment in common stocks that its investment
adviser considers to be undervalued.

                                        1
                         SIGNIFICANT ACCOUNTING POLICIES

- -   SECURITY VALUATION - Investments are stated at value. Each equity security
traded on a securities exchange shall be valued at the last current sale price
as of the time of valuation on the exchange on which the security is principally
traded (the "principal exchange"), or lacking any current reported sale on the
principal exchange at the time of valuation, at the most recent bid quotation on
the principal exchange. Each over-the-counter security traded in the Nasdaq
Stock Market ("Nasdaq") shall be valued at the Nasdaq Official Closing Price
("NOCP"), as determined by Nasdaq, or lacking an NOCP, the last current reported
sale price as of the time of valuation on Nasdaq, or lacking any current
reported sale on Nasdaq at the time of valuation, at the most recent bid
quotation on Nasdaq. For certain fixed-income securities, Skyline Funds' Board
of Trustees has authorized the use of market valuations provided by an
independent pricing service. Short-term instruments with sixty days or less to
maturity are valued at amortized cost which approximates market value.
Securities or other assets for which market quotations are not readily
available, which may include certain restricted securities, are valued at a fair
value as determined in good faith by the Skyline Funds' Board of Trustees or a
committee thereof.

- -   SECURITY TRANSACTIONS AND INVESTMENT INCOME - Security transactions are
accounted for on the trade date (date the order to buy or sell is executed) and
dividend income is recorded on the ex-dividend date. Interest income is recorded
on an accrual basis and includes amortization of premiums and discounts.
Realized gains and losses from security transactions are reported on an
identified cost basis.

- -   FUND SHARE VALUATION - Fund shares are sold and redeemed on a continuous
basis at net asset value. Net asset value per share is determined as of the
close of regular session trading on the New York Stock Exchange (normally 3:00
p.m. Central Time), each day that the Exchange is open for trading. The net
asset value per share is determined by dividing the value of all securities and
other assets, less liabilities, by the number of shares of the Fund outstanding.

- -   FEDERAL INCOME TAXES AND DIVIDENDS TO SHAREHOLDERS - It is the Fund's policy
to comply with the special provisions of the Internal Revenue Code applicable to
regulated investment companies and, in the manner provided therein, to
distribute

                                       18
<Page>

substantially all of its taxable income to shareholders. Such provisions were
complied with and, therefore, no federal income taxes have been accrued in the
accompanying financial statements.

Dividends payable to its shareholders are recorded by the Fund on the
ex-dividend date. The timing and characterization of certain income and capital
gain distributions are determined annually in accordance with Federal income tax
regulations that may differ from accounting principles generally accepted in the
United States. As a result, net investment income or loss and net realized gain
or loss for a reporting period may differ from the amount distributed during
such period. In addition, the Fund may periodically record reclassifications
among certain capital accounts to reflect differences between financial
reporting and income tax purposes. These reclassifications have no impact on the
net asset value of the Fund. Accordingly, at December 31, 2003, the following
reclassifications were recorded:

</Table>

On December 17, 2003, a distribution of $1.55614 per share was declared. The
dividend was paid on December 19, 2003, to shareholders of record on December
18, 2003.

The tax character of distributions paid during 2003 is as follows:

As of December 31, 2003, the components of distributable earnings on a tax basis
were as follows:

                                                                   NET

           $  13,245,321     $         0     $     822,895   $  124,069,522
</Table>

The differences between book-basis and tax-basis unrealized
appreciation/(depreciation) is attributable primarily to the estimated tax
deferral on wash sales and return of capital distributions received from
investments in real estate investment trusts.

- -   LINE OF CREDIT - The Fund has a $3 million committed revolving credit
facility for temporary or emergency purposes, including the meeting of
redemption requests that otherwise might require the untimely disposition of
securities. The Adviser pays a commitment fee of 10 basis points per annum of
the average daily unutilized portion

                                       19
<Page>

of the committed line of credit not utilized. Under the terms of the credit
agreement, interest on each loan would be fixed at the prime rate less 150 basis
points. During 2003, there were no loans outstanding under the credit facility.

- -   Use of Estimates - The preparation of financial statements in conformity
with accounting principles generally accepted in the United States requires
management to make estimates and assumptions that affect the amounts reported in
the financial statements and accompanying notes. Actual results may differ from
those estimates.

                                        2
                          TRANSACTIONS WITH AFFILIATES

For the Adviser's management and advisory services and the assumption of most of
the Fund's ordinary operating expenses, the Fund incurs a monthly comprehensive
fee based on its average daily net assets at the annual rate of 1.50% of the
first $200 million, 1.45% of the next $200 million, 1.40% of the next $200
million, and 1.35% of any excess over $600 million. The total comprehensive
management fee incurred for the year ended December 31, 2003 was $6,246,221.

Certain officers and trustees of the Skyline Funds are also officers, limited
partners or shareholders of limited partners of the Adviser. The Fund makes no
direct payments to the officers or trustees who are affiliated with the Adviser.
For the year ended December 31, 2003, the Fund incurred fees of $55,422 to its
unaffiliated trustees.

The Fund provides a deferred compensation plan for its trustees who are not
officers, limited partners or shareholders of limited partners of the Adviser.
Under the deferred compensation plan, trustees may elect to defer all or a
portion of their compensation. Amounts deferred are retained by the Fund, and to
the extent permitted by the 1940 Act, as amended, may be invested in the common
shares of the Fund, as selected by the trustees. Investments in such funds are
reflected as in "Other Assets" on the Statement of Assets and Liabilities at
December 31, 2003. Appreciation/depreciation and distributions received from
these investments are recorded with an offsetting increase/decrease in the
deferred compensation obligation and do not affect the net asset value of the
Fund.

REPORT OF INDEPENDENT AUDITORS

To the Shareholders of Skyline Special Equities Portfolio and the Board of
Trustees of Skyline Funds

We have audited the accompanying statement of assets and liabilities, including
the portfolio holdings, of Skyline Special Equities Portfolio (the "Fund") as of
December 31, 2003, the related statements of operations for the year then ended,
changes in 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.
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.

We conducted our audits in accordance with auditing standards generally accepted
in the 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
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights. Our procedures included
confirmation of investments owned as of December 31, 2003, by correspondence
with the custodian. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. 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
Skyline Special Equities Portfolio at December 31, 2003, the results of its
operations for the year then ended, 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 five years in the period then ended, in conformity with accounting
principles generally accepted in the United States.

FEDERAL TAX STATUS OF 2003 DIVIDENDS

Capital gain dividends paid to you, whether received in cash or reinvested in
shares, must be included in your federal income tax return and must be reported
by the Fund to the Internal Revenue Service in accordance with U.S. Treasury
Department regulations. Short-term capital gain dividends paid to you are
taxable as ordinary income. Long-term capital gain dividends paid to you are
taxable as long-term capital gain income regardless of how long you have held
Fund shares. Distributions as a return of capital are not taxable, but reduce
the cost basis of shares held.

MANAGEMENT OF SKYLINE

The Board of Trustees serve indefinite terms of unlimited duration so long as a
majority of trustees have been elected by Skyline's shareholders. The trustees
appoint their own successors, provided that at least two-thirds of the trustees,
after such appointment, have been elected by Skyline's shareholders. Skyline's
shareholders may remove a trustee, with or without cause, upon the declaration
in writing or vote of two-thirds of Skyline's outstanding shares. A trustee may
be removed with or without cause upon the written declaration of a majority of
the trustees.

The names of the trustees and officers of Skyline, the year each was first
elected or appointed to office, their principal business occupations and other
directorships they have held during at least the last five years, are shown

executive and senior financial officers (the "Code").

(b) No disclosures are required by this Item 2(b).

(c) During the period covered by the report, registrant did not make any
amendments to the provisions of the Code.

(d) During the period covered by the report, registrant did not grant any

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

Registrant's board of trustees has determined that Richard K. Pearson, a member
of the registrant's Committee of the Independent Trustess, qualifies as an
"audit committee financial expert," as such term is defined in Instruction 2(b)
to Item 3 of Form N-CSR. Mr. Pearson is "independent" as such term is defined in
paragraph (a)(2) of Item 3 of Form N-CSR.

Under applicable securities laws, a person who is determined to be an audit
committee financial expert will not be deemed an "expert" for any purpose,
including without limitation for the purposes of Section 11 of the Securities
Act of 1933, as a result of being designated or identified as an audit committee
financial expert. The designation or identification of a person as an audit
committee financial expert does not impose on such person any duties,
obligations, or liabilities that are greater than the duties, obligations, and
liabilities imposed on such person as a member of the audit committee and board
of trustees in the absence of such designation or identification.

principal accountants and management to review and pre-approve all audit
services to be provided by the principal accountants.

The Committee of Independent Trustees shall pre-approve all non-audit
services to be provided by the principal accountants to the registrant;
provided that the pre-approval requirement does not apply to non-audit
services that (i) were not identified as such at the time of the pre-approval

operations or financial reporting of the registrant; provided that the
pre-approval requirement does not apply to non-audit services that (i) were
not identified as such at the time of the pre-approval and (ii) do not
aggregate more than 5% of total revenue paid to the principal accountants by
the registrant for all services and by the registrant's investment adviser
for services where the nature of the services provided have a direct impact
on the operations or financial reporting of the registrant during the fiscal
year in which those services are provided, if the Committee of Independent
