ANNUAL REPORT

SEPTEMBER 30, 2005

Midanek/Pak Ultrashort Duration Fund

November 17, 2005

Dear Fellow Shareholder,

Once again we have the pleasure of addressing you regarding our Fund. We have had a wonderful year as we managed and marketed the fund. We have had the opportunity to meet and talk with many of you as well as many “future shareholders.” Our marketing efforts together with those of Sincere & Co. within the advisor community should continue to yield many benefits in the coming year.

The old saying “may you live in interesting times” certainly applied to the bond market during the last year. We have indeed been in an interesting time. The Fed has tightened relentlessly all year, raising the Fed Funds rate from 1.25% last October, up to 4% as this is being written. As we suggested in our last letter, they are not quite done yet and we think, should at least reach 4.5% before pausing. Despite this aggressive posture from the Fed, interest rates on longer maturity securities barely budged over the year ended September 30, 2005. In fact, the interest rate on the thirty year treasury actually fell.

This yield curve behavior, with short rates rising so significantly, has made life difficult for ultra short managers. It has been difficult for our fund, as we have anticipated a steepening of the yield curve (rising long rates), which has not come, for the last six months. As a result, for the twelve months ended September 30, 2005, the Midanek/Pak Ultrashort Duration Fund (2.52%) modestly outperformed the iMoneyNet First Tier Institutional Money Market Index (2.39%) and underperformed the Merrill Lynch Three-Month U.S. Treasury Bill Index (2.61%). However, despite an almost doubling of short-term yields and a 275 basis point increase in the fund’s rate, your fund has continued to provide positive returns in each month (see monthly returns below).

Oct. ’04	Nov. ’04	Dec. ’04	Jan. ’05	Feb. ’05	Mar. ’05
0.32%	0.13%	0.18%	0.20%	0.20%	0.12%
Apr. ’05	May ’05	Jun. ’05	Jul. ’05	Aug. ’05	Sept. ’05
0.32%	0.24%	0.24%	0.13%	0.27%	0.16%
Past performance does not guarantee future results.

The coming year should be an easier one for ultrashort funds. The Fed will complete its tightening in early 2006. After that, the “new Fed” under Chairman Bernanke should be comfortable maintaining the status quo for much of the year. We believe, this will create an excellent environment for the ultra short fund sector, as the short end of the curve should be providing a reasonable return (almost equal to that offered by longer maturities), and in excess of the inflation rate. We feel your fund is positioned to benefit from this environment.

It is important to us to stay in touch with our shareholders. We encourage you to contact us either on our website (www.MPAinvest.com) or by phone at 1-877-MIDANEK (643-2635).

Mutual fund investing involves risk. Principal loss is possible. Investments in debt securities typically decrease in value when interest rates rise. This risk is usually greater for longer-term debt securities.

The Fund’s investment objectives, risks, charges and expenses must be considered carefully before investing. The prospectus contains this and other important information about the investment company, and it may be obtained by calling (877) 840-1200, or visiting www.MPAinvest.com. Read it carefully before investing.

MIDANEK/PAK ULTRASHORT DURATION FUND

Comparison of the change in value of a $10,000 investment in the Midanek/Pak Ultrashort Duration Fund vs the Merrill Lynch Three-Month U.S. Treasury Bill Index and the iMoneyNet First Tier Institutional Money Market Index

Total Return:	Since Inception*
Midanek/Pak Ultrashort Duration Fund	2.52%
Merrill Lynch Three-Month U.S. Treasury Bill Index	2.61%
iMoneyNet First Tier Institutional Money Market Index	2.39%

Performance data quoted represents past performance; past performance does not guarantee future results. The 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 of the Fund may be lower or higher than the performance quoted. Performance data current to the most recent month end may be obtained by calling 1-877-840-1200.

This chart illustrates the performance of a hypothetical $10,000 investment made in the Fund one year ago. Returns reflect the reinvestment of dividends and capital gain distributions. Fee waivers are in effect. In the absence of fee waivers, returns would be reduced. The performance data and graph do not reflect the deduction of taxes that a shareholder may pay on dividends, capital gain distributions, or redemption of Fund shares. This chart does not imply any future performance.

The Merrill Lynch Three-Month U.S. Treasury Bill Index is an unmanaged index of Treasury securities that assumes reinvestment of all income.

The iMoneyNet First Tier Institutional Money Market Index includes only non-government institutional funds which hold only first tier securities. First tier securities include U.S. Treasury securities, repurchase agreements, time deposits, domestic bank obligations, foreign bank obligations, first tier commercial paper, asset-backed commercial paper and floating rate notes.

Indices do not incur expenses and are not available for investment.

* The since inception returns for the Fund and the Merrill Lynch Three-Month U.S. Treasury Bill Index are from October 1, 2004 through September 30, 2005. The since inception return for the iMoneyNet First Tier Institutional Money Market Index is from September 30, 2004 through September 30, 2005.

EXPENSE EXAMPLE

at September 30, 2005 (Unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments; redemption fees; and exchange fees; and (2) ongoing costs, including management fees; distribution and/or service 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 (4/1/05 - 9/30/05).

Actual Expenses

The first line of the table below provides information about actual account values and actual expenses, with actual net expenses being limited to 0.55% per the advisory agreement. Although the Fund charges no sales load or transaction fees, you will be assessed fees for outgoing wire transfers, returned checks, and stop payment orders at prevailing rates charged by U.S. Bancorp Fund Services, LLC, the Fund’s transfer agent.The example below includes, but is not limited to, management fees, fund accounting, custody and transfer agent fees. 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 = 8.6), 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 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 the 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 sales charges (loads), redemption fees, or exchange fees. Therefore, the second line of the table 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.

	Beginning	Ending	Expenses Paid
	Account Value	Account Value	During Period
	4/1/05	9/30/05	4/1/05 - 9/30/05*

Hypothetical (5% return before expenses)	$1,000.00	$1,022.31	$2.79

* Expenses are equal to the Fund’s annualized expense ratio of 0.55%, multiplied by the average account value over the period, multiplied by 183 (days in most recent fiscal half-year)/365 days to reflect the one-half year expense.

NOTES TO FINANCIAL STATEMENTS

at September 30, 2005

NOTE 1 - ORGANIZATION

The Midanek/Pak Ultrashort Duration Fund (the “Fund”) is a series of Advisors Series Trust (the “Trust”), which is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is to seek maximum total return consistent with preservation of capital. The Fund pursues this objective by investing primarily in debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities. The Fund commenced operations on October 1, 2004.

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by the Fund. These policies are in conformity with accounting principles generally accepted in the United States of America.

A. Security Valuation: The Fund’s investments are carried at fair value.  Securities that are primarily traded on a national securities exchange shall be valued at the last sale price on the exchange on which they are primarily traded on the day of valuation or, if there has been no sale on such day, at the mean between the bid and asked prices. Securities primarily  traded in the NASDAQ National Market System for which market quotations are readily available shall be valued using the NASDAQ Official Closing Price (“NOCP”). If the NOCP is not available, such securities shall be valued at the last sale price on the day of valuation, or if there has been no sale on such day, at the mean between the bid and asked prices. Over-the-counter securities which are not traded in the NASDAQ National Market System shall be valued at the most recent trade price. Debt securities (other than short-term obligations maturing in sixty days or less), including listed issues, are valued at market on the basis of valuations furnished by an independent pricing service which utilizes both dealer-supplied valuations and formula-based techniques. Short-term investments which mature in 60 days or less are valued at amortized cost, which approximates market value. Securities for which market quotations are not readily available, or if the closing price doesn’t represent fair value, are valued following procedures approved by the Board of Trustees. These procedures consider many factors, including type of security, size of holding, trading volume and news events. As of September 30, 2005, the Fund held fair value securities with a value of $849,600 or 14.4% of total net assets.

B. Federal Income Taxes: It is the Fund’s policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required.

16

NOTES TO FINANCIAL STATEMENTS (Continued)

at September 30, 2005

C. Security Transactions, Dividends and Distributions: Security transactions are accounted for on the trade date. Discounts and premiums on securities purchased are amortized over the life of the respective security. Realized gains and losses on securities sold are determined on the basis of identified cost. Distributions to shareholders are recorded on the ex-dividend date. The Fund declares and pays dividends of net investment income daily and distributes net realized gains, if any, annually. The amount of dividends and distributions to shareholders from net investment income and net realized capital gains is determined in accordance with federal income tax regulations which differ from accounting principles generally accepted in the United States of America. To the extent these book/tax differences are permanent such amounts are reclassified within the capital accounts based on their federal tax treatment.

D. Use of Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 increases and decreases in net assets during the reporting period. Actual results could differ from those estimates.

E. Reclassification of Capital Accounts: Accounting principles generally accepted in the United States of America require that certain components of net assets relating to permanent differences be reclassified between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share. For the year ended September 30, 2005, the Fund decreased accumulated net investment loss and paid-in capital by $93 due to certain permanent book and tax differences.

NOTES TO FINANCIAL STATEMENTS (Continued)

at September 30, 2005

The Fund is responsible for its own operating expenses. The Advisor has contractually agreed to reduce fees payable to it by the Fund and to pay Fund operating expenses to the extent necessary to limit the Fund’s aggregate annual operating expenses to 0.55% of average net assets. Any such reduction made by the Advisor in its fees or payment of expenses which are the Fund’s obligation are subject to reimbursement by the Fund to the Advisor, if so requested by the Advisor, in subsequent fiscal years if the aggregate amount actually paid by the Fund toward the operating expenses for such fiscal year (taking into account the reimbursement) does not exceed the applicable limitation on Fund expenses. The Advisor is permitted to be reimbursed only for fee reductions and expense payments made in the previous three fiscal years. Any such reimbursement is also contingent upon Board of Trustees review and approval at the time the reimbursement is made. Such reimbursement may not be paid prior to the Fund’s payment of current ordinary operating expenses. For the year ended September 30, 2005, the Advisor reduced its fees and absorbed Fund expenses in the amount of $153,052. No amounts were reimbursed to the Advisor. Cumulative expenses subject to recapture pursuant to the aforementioned conditions and the year of expiration are as follows:

Year	Amount
2008	$153,052

U.S. Bancorp Fund Services, LLC (the “Administrator”) acts as the Fund’s Administrator under an Administration Agreement. The Administrator prepares various federal and state regulatory filings, reports and returns for the Fund; prepares reports and materials to be supplied to the Trustees; monitors the activities of the Fund’s custodian, transfer agent and accountants; coordinates the preparation and payment of the Fund’s expenses and reviews the Fund’s expense accruals. For its services, the Administrator receives a monthly fee at the following annual rates:

Fund asset level	Fee rate
Less than $20 million	$30,000
$20 million to less than $100 million	0.15% of average daily net assets
$100 million to less than $200 million	0.10% of average daily net assets
More than $200 million	0.05% of average daily net assets

For the year ended September 30, 2005, the Fund incurred $30,000 in administration fees.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees

Advisors Series Trust and

Shareholders of

Midanek/Pak Ultrashort Duration Fund

We have audited the accompanying statement of assets and liabilities of the Midanek/Pak Ultrashort Duration Fund, a series of Advisors Series Trust (the “Trust”), including the schedule of investments, as of September 30, 2005, and the related statements of operations, changes in net assets and the financial highlights for the year then ended. These financial statements and financial highlights are the responsibility of the Trust’s management.  Our responsibility is to express an opinion on these financial statements and financial highlights based on our audit.

We conducted our audit 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 and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Trust’s internal control over financial reporting. Our audit included 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 Trust’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of September 30, 2005, 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 audit provides 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 the Midanek/Pak Ultrashort Duration Fund, as of September 30, 2005, and the results of its operations, the changes in its net assets and the financial highlights for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

Share price and returns will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Statements and other information herein are dated and are subject to change.

Item 2. Code of Ethics.

The registrant has adopted a code of ethics that applies to the registrant’s principal executive officer and principal financial officer. The registrant has not made any amendments to its code of ethics during the period covered by this report. The registrant has not granted any waivers from any provisions of the code of ethics during the period covered by this report.

A copy of the registrant’s Code of Ethics is filed herewith.

Item 3. Audit Committee Financial Expert.

The registrant’s board of trustees has determined that it does not have an audit committee financial expert serving on its audit committee. At this time, the registrant believes that the experience provided by each member of the audit committee together offers the registrant adequate oversight for the registrant’s level of financial complexity.

Item 4. Principal Accountant Fees and Services.

The registrant has engaged its principal accountant to perform audit services, audit-related services, tax services and other services during the last fiscal year. “Audit services” refer to performing an audit of the registrant's annual financial statements or services that are normally provided by the accountant in connection with statutory and regulatory filings or engagements for that fiscal year. “Audit-related services” refer to the assurance and related services by the principal accountant that are reasonably related to the performance of the audit. “Tax services” refer to professional services rendered by the principal accountant for tax compliance, tax advice, and tax planning. There were no “other services” provided by the principal accountant. The following table details the aggregate fees billed or expected to be billed for the last fiscal year for audit fees, audit-related fees, tax fees and other fees by the principal accountant.

	FYE 9/30/2005
Audit Fees	$13,800
Audit-Related Fees	N/A
Tax Fees	$2,200
All Other Fees	N/A

The audit committee has adopted pre-approval policies and procedures that require the audit committee to pre-approve all audit and non-audit services of the registrant, including services provided to any entity affiliated with the registrant. All of the principal accountant’s hours spent on auditing the registrant’s financial statements were attributed to work performed by full-time permanent employees of the principal accountant.

The following table indicates the non-audit fees billed or expected to be billed by the registrant’s accountant for services to the registrant and to the registrant’s investment adviser (and any other controlling entity, etc.—not sub-adviser) for the last year. The audit committee of the board of trustees has considered whether the provision of non-audit services that were rendered to the registrant's investment adviser is compatible with maintaining the principal accountant's independence and has concluded that the provision of such non-audit services by the accountant has not compromised the accountant’s independence.

The Principal Officers shall act in good faith, responsibly, with due care, competence and diligence, without misrepresenting material facts or allowing their independent judgment to be subordinated or compromised.
