AVAILABILITY OF PORTFOLIO SCHEDULE
- ----------------------------------

The Fund files its complete  schedule of portfolio  holdings with the Securities
and Exchange  Commission ("SEC") for the first and third quarters of each fiscal
year on Form N-Q.  The Fund's Form N-Qs are  available  at the SEC's  website at

Reference  Room in  Washington  DC.  Information  on the operation of the Public
Reference Room may be obtained by calling 1-800-SEC-0330.

ABOUT YOUR FUND'S EXPENSES - (UNAUDITED)
- ----------------------------------------

As a shareholder of the Fund, you incur ongoing costs, including management fees
and other Fund expenses.  This 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 period and held for
the entire period from October 1, 2004 to March 31, 2005.


                                       1




SUMMARY OF FUND'S EXPENSES - (UNAUDITED)
- --------------------------


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  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 = 8.60),  then multiply the result by the number
in the first line under the heading  entitled  "Expenses  Paid During Period" to
estimate the expenses you paid on your account during this 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 Fund's actual  expense
ratios 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 the other funds.

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

NOTE 1.  ORGANIZATION

The Iron Market  Opportunity  Fund (the "Fund") was  organized as a  diversified
series of AmeriPrime  Advisors Trust (the "Trust") on July 1, 2001 and commenced
operations  October  11,  2001.  The  Trust is an  open-end  investment  company
established  under the laws of Ohio by an  Agreement  and  Declaration  of Trust
dated August 3, 1999 (the "Trust  Agreement").  The Trust Agreement  permits the
Board of Trustees of the Trust (the  "Board")  to issue an  unlimited  number of
shares of beneficial interest of separate series. The Fund is one of a series of
funds  currently  offered by the Trust.  The Fund's  investment  objective is to
maximize total return while  maintaining low volatility in share price. The Fund
invests  primarily  in a broad  range  of  fixed  income  securities  (including
investments, which may be extensive, in other mutual funds that invest primarily
in  fixed  income  securities).  The  investment  adviser  to the  Fund  is Iron
Financial Management, Inc. (the "Adviser").

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant  accounting  policies  followed by the
Fund in the preparation of its financial statements.

Securities  Valuations - Equity securities  generally are valued by using market
quotations,  but may be valued on the  basis of  prices  furnished  by a pricing
service when the Adviser believes such prices accurately reflect the fair market
value of such  securities.  Securities that are traded on any stock exchange are
generally valued by the pricing service at the last quoted sale price. Lacking a
last sale price, an exchange traded security is generally  valued by the pricing
service at its last bid price.  Securities traded in the NASDAQ over-the-counter
market are  generally  valued by the  pricing  service  at the  NASDAQ  Official
Closing  Price.  When  market  quotations  are not readily  available,  when the
Adviser  determines  that the  market  quotation  or the price  provided  by the
pricing  service does not  accurately  reflect the current  market value or when
restricted or illiquid  securities are being valued,  such securities are valued
as  determined  in good faith by the  Adviser,  in  conformity  with  guidelines
adopted by and subject to review of the Board.

Fixed income securities generally are valued by using market quotations, but may
be valued on the basis of prices furnished by a pricing service when the Adviser
believes  such  prices  accurately   reflect  the  fair  market  value  of  such
securities.  A pricing service  utilizes  electronic data processing  techniques
based on yield spreads  relating to securities with similar  characteristics  to
determine prices for normal institutional-size  trading units of debt securities
without  regard  to sale or bid  prices.  If the  Adviser  decides  that a price
provided  by the pricing  service  does not  accurately  reflect the fair market
value of the  securities,  when prices are not readily  available from a pricing
service, or when restricted or illiquid securities are being valued,  securities
are valued at fair value as determined in good faith by the Adviser,  subject to
review  of the  Board of  Trustees.  Short  term  investments  in  fixed  income
securities  with  maturities  of less  than  60 days  when  acquired,  or  which
subsequently  are within 60 days of maturity,  are valued by using the amortized
cost method of valuation,  which the Board has  determined  will  represent fair
value.

Federal  Income Taxes - There is no provision for federal  income tax. Each Fund
intends to continue to qualify  each year as a  "regulated  investment  company"
under  Subchapter  M of the  Internal  Revenue  Code of  1986,  as  amended,  by
distributing all of its taxable income. If the required amount of net investment
income is not distributed, the Fund could incur a tax expense.

Security  Transactions and Related Income - The Fund follows  industry  practice
and records security transactions on the trade date. The specific identification
method is used for  determining  gains or losses for  financial  statements  and
income tax purposes.  Dividend  income is recorded on the  ex-dividend  date and
interest  income is  recorded on an accrual  basis.  Discounts  and  premiums on
securities purchased are amortized over the life of the respective securities.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

Distributions  to  Shareholders  - The Fund intends to distribute all of its net
investment  income, if any, as dividends to shareholders on an annual basis. The
Fund intends to  distribute  its net realized  long-term  capital  gains and net
realized  short-term capital gains, if any, at least once a year.  Distributions
to shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date.

NOTE 3.  FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the  management  agreement,  (the  "Agreement"),  the Adviser
manages the Fund's investments subject to approval of the Board. As compensation
for its  management  services,  the Fund is  obligated  to pay the Adviser a fee
computed  and accrued  daily and paid  monthly at an annual rate of 1.00% of the
average daily net assets of the Fund. Effective October 1, 2003, the Adviser has
contractually  agreed to waive one-half of its management  fees through  January
31,  2006.  For the six months ended March 31,  2005,  the Adviser  earned fees,
before the waiver,  totaling,  $906,142 and after the waiver,  of  $453,071.  At
March 31, 2005, the Fund owed the Advisor $95,044.

The Trust  retains  Unified  Fund  Services,  Inc.  ("Unified"),  a wholly owned
subsidiary of Unified  Financial  Services,  Inc., to manage the Fund's business
affairs  and  provide  the Fund  with  administrative  services,  including  all
regulatory  reporting and necessary  office  equipment  and  personnel.  Unified
receives  a monthly  fee from the Fund  equal to an annual  rate of 0.10% of the
Fund's assets up to $50 million,  0.07% of the Fund's assets from $50 million to
$100  million,  and 0.05% of the Fund's  assets over $100 million  (subject to a
minimum  fee of $2,500 per  month).  For the six months  ended  March 31,  2005,
Unified earned fees of $59,587 for administrative services provided to the Fund.
A trustee  and the  officers  of the  Trust are  members  of  management  and/or
employees of Unified and/or  shareholders of Unified  Financial  Services,  Inc.
(the parent of Unified).

The Trust  retains  Unified to act as the Fund's  transfer  agent and to provide
fund accounting services. For its services as transfer agent, Unified receives a
monthly fee from the Fund of $1.25 per shareholder (subject to a minimum monthly
fee of $1,250).  For the six months ended March 31, 2005, Unified earned fees of
$7,693 from the Fund for transfer  agent  services  provided to the Fund and was
reimbursed for $1,381 of out-of-pocket  expenses incurred in providing  transfer
agent  services  to the  Fund.  For its  services  as fund  accountant,  Unified
receives  an annual fee from the Fund equal to 0.05% of the Fund's  assets up to
$50 million,  0.04% of the Fund's assets from $50 million to $100  million,  and
0.03% of the Fund's assets over $100 million (subject to various monthly minimum
fees, the maximum being $1,667 per month for assets of $10 million or more). For
the six months  ended March 31,  2005,  Unified  earned fees of $34,664 from the
Fund for fund accounting services provided to the Fund.

Unified Financial  Securities,  Inc. (the  "Distributor")  acts as the principal
distributor of the Fund's shares. The Fund has adopted a plan,  pursuant to Rule
12b-1  under the  Investment  Company  Act of 1940 that  permits the Fund to pay
certain  distribution and promotion  expenses related to marketing shares of the
Fund;  however the plan has not been activated.  As a result there were no 12b-1
payments  made to the  Distributor  for the six months  ended March 31,  2005. A
Trustee has an  ownership  interest in Unified  Financial  Services,  Inc.  (the
parent  company of the  Distributor),  and  certain  officers of the Trust are a
director  and/or  officers of the  Distributor  and/or  shareholders  of Unified
Financial  Services,  Inc.  As a  result,  those  persons  may be  deemed  to be
affiliates of the Distributor.

At March 31, 2005,  the  aggregate  cost of  securities  for federal  income tax
purposes was $230,250,263.

NOTE 5. ESTIMATES

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the reported  amounts of increases and  decreases in net assets from  operations
during the reporting period. Actual results could differ from those estimates.

NOTE 6.  BENEFICIAL OWNERSHIP

The beneficial ownership, either directly or indirectly, of more than 25% of the
voting  securities of a fund creates a presumption of control of the fund, under
Section  2(a)(9) of the  Investment  Company Act of 1940.  As of March 31, 2005,
Fabco & Co. owned 69.59% of the Fund, for the benefit of others.

NOTE 7. DISTRIBUTIONS TO SHAREHOLDERS

The tax character of distributions paid during fiscal years 2004 and 2003 was as
follows:

                                            2004                2003

NOTE 7. DISTRIBUTIONS TO SHAREHOLDERS - CONTINUED

For the fiscal year ended  September 30, 2004 and the six months ended March 31,
2005, the Fund paid quarterly  distributions  of net investment  income totaling
$0.2804 and $0.1156 per share,  respectively.  Capital gain distributions in the
amount of $0.0939 per share were paid  December 30,  2003,  to  shareholders  of
record  on  December  29,  2003.   The  Fund  did  not  make  any  capital  gain
distributions for the six months ended March 31, 2005.

As of September 30, 2004, the components of distributable  earnings (accumulated
losses) on a tax basis were as follows:

Undistributed ordinary income/(accumulated losses)            $      42,510
Undistributed long-term capital gain/(accumulated losses)          (547,490)
Unrealized appreciation/(depreciation)                             (659,077)
                                                             ---------------
                                                              $  (1,164,057)
                                                             ===============


The  difference  between  book basis and tax basis  unrealized  depreciation  is
attributable primarily to the tax deferral of losses on wash sales.
