Dear Fellow Shareholder:

We are pleased to present our combined semi-annual report for the Chase Growth Fund (NASDAQ: CHASX, CHAIX) and the Chase Mid-Cap Growth Fund (NASDAQ: CHAMX) for the period ending March 31, 2009.  At the end of the first quarter, over 17,000 shareholders have $483 million invested in the Chase Growth Fund, while the Chase Mid-Cap Growth Fund has $20.6 million with almost 200 shareholders.  On January 28, 2007, we initiated a Substantial Investor Class of shares in the Chase Growth Fund (CHAIX) with an annual expense ratio lower by 0.25% for direct shareholders who have invested $1 million or more.  At the end of the first quarter, over 100 shareholders had $115 million invested in that class.  We appreciate the trust all of you have placed in our management and we want to extend a special welcome to new shareholders since our November 12th letter.  

Fund Performance Overview

While the specifics behind the Funds’ performance drivers and our thoughts on the current market outlook are detailed in separate sections below, we want to point out a couple of factors surrounding the recent “bear market rally.”  As those who are familiar with our process know, we focus on companies with a strong earnings history along with strong fundamentals and technicals but which are selling at a reasonable price.  This process has historically limited our participation in rallies that follow a bear market, which often favor lower quality, depressed stocks.  However, we are pleased that we have participated more in this current rally than we have in most of those in the past.  While past performance is no guarantee of future results, whether the rally is sustained and the good quality stocks which our process favors begin to take more of a leading role, or if the market retreats again and our stocks have better defensive qualities, we believe that our process allows us to be well positioned in either scenario.

Our investment process combines fundamental, technical, and quantitative analysis. We seek good quality companies that are leaders in their industries and enjoy above average, sustainable earnings growth with strong balance sheets to support that growth.  Both the Chase Growth Fund and the Chase Mid-Cap Growth Fund portfolios include a diversified group of companies that we believe represent relatively outstanding investment opportunities.  The following is a discussion of the components and drivers of the performance of each fund, as well as how the characteristics of the underlying stocks compare with those in the Russell 1000® Growth Index and the Russell MidCap® Growth Index, respectively.

Chase Growth Fund (CHASX and CHAIX)

	6 months ended 3/31/09
Chase Growth Fund Class N (CHASX)	-25.96%
Chase Growth Fund SI Class (CHAIX)	-25.91%
Lipper Large Cap Growth Funds Index	-26.60%
Russell 1000® Growth Index	-25.97%
S&P 500® Index	-30.54%

Lipper Analytics Services, Inc.1 ranked the Chase Growth Fund Class N Shares (based on total return) #5 out of 285, #48 out of 563, #132 out of 674 and #187 out of 789 funds in its Large Cap Growth Universe for the ten years, five years, three years and one year periods ended 3/31/09, respectively.  Past performance is not a guarantee of future results.

Chase Funds

On March 31st the Chase Growth Fund was invested in 32 stocks, which on average were rated A quality (with A++ being the strongest rating of relative financial strength and C++ being a satisfactory rating) by Value Line.  They range in market capitalization from $6.4 billion (Range Resources) to $338.9 billion (Exxon Mobil).

For the last six months, the Chase Growth Fund’s performance was helped by our overweight position in the health care sector, but this overweight position (now reduced) has been a drag on relative performance since the March low.  Our continued focus on reasonably priced, high quality, large cap growth stocks with consistent earnings growth enabled us to avoid most of the financial firms directly involved in the credit crisis, but our lack of exposure to this area has hurt relative performance since the March low, as some of these companies as well as the most depressed stocks in other areas have enjoyed the strongest rebound rally. For the six months ended March 31st, our five best performing stocks were TJX Companies +20.79%, AutoZone +19.22%, Cisco Systems +17.18%, Intuit +14.57% and Corning +7.79%.

The chart below compares the characteristics of Chase Growth Fund stocks to the stocks in the Russell 1000® Growth Index.  Chase Growth Fund stocks have higher five-year average annual earnings per share growth rates of 28% vs. 23% for the Russell 1000® Growth Index.  They have also been more profitable with a Return on Equity of 29% vs. 25%, and less debt with Debt to Total Capital of 23% vs. 26%.  They sell at a slightly lower price/earnings multiple as the Russell 1000® Growth Index (15.3X vs. 15.7X) based on 2009 estimated earnings.  Our stocks are selling at 0.55 times their five-year historical growth rates compared to 0.69 times for the Russell 1000® Growth Index and 0.64 times their projected reinvestment rates compared to 0.95 times for the Russell 1000® Growth Index.

	6 months ended 3/31/09
Chase Mid-Cap Growth Fund (CHAMX)	-27.17%
Lipper MidCap Growth Funds Index	-29.44%
Russell Midcap® Growth Index	-29.80%

Lipper Analytics Services, Inc.1 ranked the Chase Mid-Cap Growth Fund (based on total return) #53 out of 398, #170 out of 486 and #87 out of 562 funds in its Mid-Cap Growth Fund Universe for the five years, three years and one year periods ended 3/31/09, respectively.  Past performance is not a guarantee of future results.

On March 31st the Chase Mid-Cap Growth Fund was invested in 41 stocks, which on average were rated B++ quality by Value Line.  They range in market capitalization from $0.7 billion (Genesee & Wyoming) to $12.6 billion (Apollo Group).

The Chase Mid-Cap Growth Fund has declined less than the benchmarks during the last six months.  Like the Chase Growth Fund, we avoided some of the more troubled areas of the market by focusing on consistency and stability of earnings growth.  Our heavier emphasis on some of the more defensive consumer discretionary and consumer staples stocks helped relative performance, but these areas have lagged some of the more depressed areas since the March lows.  Within our midcap growth mandate, we have continued to favor some of the larger, more stable earning growth companies.  For the six months ended March 31st, our five best performing stocks were Dollar Tree Stores +22.46%, O’Reilly Automotive +19.70, Apollo Group +18.54, Priceline.com +15.12 and Mylan +14.08.

The chart below compares the characteristics of Chase Mid-Cap Growth Fund stocks to the stocks in the Russell Midcap® Growth Index.  They have slightly higher five-year average annual earnings per share growth rates of 25% vs. 23% for the Russell Midcap® Growth Index, and they have stronger balance sheets with Debt to Total Capital of only 21% vs. 27%.  They sell at a lower price/earnings multiple than the Russell Midcap® Growth Index (15.0X vs. 17.0X) based on 2009 estimated earnings.  Our mid-cap stocks are selling at 0.61 times their five-year historical growth rates compared to 0.73 times for the Russell Midcap® Growth Index and 0.75 times their projected reinvestment rates compared to 1.15 times for the Russell Midcap® Growth Index.

Market Outlook

Chase Investment Counsel Corporation’s investment process is bottom up and driven by our security selection methodology.  For shareholders who are interested in the economic and market outlook, we feel that the best way for our firm to provide this information is by presenting a thorough, and well researched compilation of relevant factors that we believe could influence the market over the near term.  Below are the remarks by Derwood Chase at our Tenth Annual Growth Funds Shareholder Meeting held on May 5, 2009.  Our Eleventh Annual Growth Funds Meeting will be held at Farmington Country Club in Charlottesville, Virginia on Monday, May 3rd, 2010.

Positive Factors

• Lowrys Research analyzes 90% Down and 90% Up Days to judge the extent of fear/panic and buying/euphoria.  With the SEC’s elimination of the Uptick Rule for shorting the 90% Up/90% Down Days figures may be distorted due to “piling on” by short sellers and then massive short covering on the market rallies.  In any case the recent rally is the best since July 2007.  The 90% Up Day on 5/4/09 resulted in a Lowry Intermediate Trend Buy Signal triggering the first stage of their 5-stage buying program.  Lowrys also had a conventional short-term Buy Signal.

• The Federal Reserve is determined to maintain low interest rates, substantial liquidity, and special lending assistance to help the economy.  It usually doesn’t pay to fight the Fed especially when they are injecting another trillion dollars into the financial markets including the purchase of $300 billion longer-maturity Treasury bonds and $700 billion mortgage securities.  The latest readings of the CPI eliminate short term inflation worries and give the Fed more flexibility.  Historically, when the Ned Davis Research Inflation Timing Model has been below zero as it was on 3/31 the DJIA has gained 12% per annum.

• Recently the Obama administration proposed a trillion dollar public private partnership to purchase troubled loans from the nations banks in an effort to free up lending institutions to provide needed liquidity for future economic growth.  As described by Deliberations, Buying Legacy Assets (toxic assets) on 5% margin and zero cost financing with the government limiting the downside risk should definitely attract some speculators.

• We expect the huge government “stimulus” program will help increase consumer spending by the middle of this year.  Unfortunately, most of it will not likely create jobs or help businesses grow.  Debt financing for many creditworthy small businesses is still very restricted.

• Last month the Financial Accounting Standards Board (FASB) announced their intention to modify “mark-to-market” accounting rules effective March 15th so that institutions which intend to and are able to hold securities to maturity will not have to take those losses in their 1Q or later interim financial reports.

• As of May 4th, the health of the global credit market remained significantly improved with the TED spread at 1.27 down from its extraordinary peak above 5 during the October credit crisis.

Chase Funds

• With Money Market funds holding near the 2/28/09 record high of $3.9 trillion, about 43% of NDR Total Stock Market Values, there is record high liquidity on the sidelines when investor confidence improves.

• A record 2,901 of 3,130 NYSE stocks traded on October 10th declined to (52 week) lows.  The market may well have registered an “internal bottom” that day even though the DJIA closed 900 points lower on November 20th at 7,552 with 1,894 new lows, and made an even lower low on March 9th at 6,547 with only 827 new lows.  This contraction in new lows, combined with the extremely oversold condition and substantial negative sentiment, created conditions for at least a sizeable bear market rally.

• On April 29th the DJIA made a recovery high above its 8,131 April 17th peak supporting the previous recovery high in the Dow Transportation Index which reconfirms the rising market trend under Dow Theory.

Risk Factors

• The S&P 500 was down -8.6% for the month of January.  As the Stock Traders Almanac documents, the full year has followed the direction of January with only 5 major errors since 1950.

• On March 31st, Ned Davis Research estimated total common stock market capitalization (currently 4,400 U.S. common stocks) stood at 62.8% of nominal GDP; down 64% from its 3/31/2000 historic peak of 174.0%, but still well above its lows of 36.3% and 32.2% respectively in 1974 and 1982 and still slightly above the 60% Norm since 1925.  Although, by some other measures, such as price to book value, equities are reasonably valued.  The S&P 500 P/B at 1.2x is well below its long-term average although still above its lows of 1974 and 1980-82.  Trying to value a market during a recession is difficult because earnings are declining and P/E ratios have recently been rising despite the falling market.

• Consumers have too much debt and financial organizations too much leverage as well as too many poor quality, or at least illiquid loans.  In reality many of our major banks are insolvent.  Their recovery will likely be hampered by the need for stricter lending requirements, increased mortgage defaults, huge additional losses on credit cards, auto loans, commercial loans and municipal financing, not to mention the spread of the crisis globally.  Meanwhile new mortgage issuance has declined drastically.

• Deleveraging will take a long time.  As defaults rise, the huge credit derivative market could implode.  According to the Bank for International Settlements, their June 2008 notional (gross OTC contract value) totals nearly $700 trillion.

• If the S&P March low was the bottom, it would have been the 3rd worst (-56.8%) decline since 1900, but also the 3rd shortest (73 weeks) of the nine bear markets that declined more than 35%.  For perspective, those declines averaged -48.9% and took on average 88 weeks.  At six of those lows (including 1982 and 1974) the S&P dividend yielded over 6% or equivalent to 410 on the S&P 500 at current dividends.

• If the S&P March low was the ultimate bottom, we would have expected a much higher level of fear with a put/call ratio over 1.00 rather than the complacent 0.64 level reached that week.

• Geopolitical uncertainties remain high and we are in the midst of an extraordinary global credit crisis, a crisis of confidence, a trend toward increasing protectionism, and the largest worldwide wealth destruction ever.  A balance sheet recession caused by excessive debt and collapsing net worth is quite different than those caused by restrictive central banks to curb inflation.  We have not experienced this type of recession since the 1930s which is why the pattern of stock market decline experienced in the 1929-1938 period is relevant.  Proposals for regulating hedge funds, leverage, and various criteria for financial institutions suggest a radically different and quite uncertain, troubling future for the finance industry.

• Corporate profit margins which had been running at very high levels, 50% higher than the peaks of the ’60s–’90s are declining as the economy continues to weaken.  Many more company specific 2009 corporate earnings estimates will likely be revised downward.

• Since 1949 the market has been down during 35% of the 236 quarters.  61% of those declines came in the first seven quarters of the President’s Term: the worst being the 5th quarter (which for the current Presidency would correspond to the 1st Quarter of 2010), the second worst the 1st quarter (for the current Presidency would correspond to the 1st Quarter of 2009, which has just ended).  (See Deliberations 1/7/09).

• The $800 billion “stimulus” bill (1,400 pages) is primarily social engineering rather than economic stimulus, saving less productive federal and state government jobs while not creating jobs or stimulating the private sector.  It will vastly increase government regulation and the U.S. budget deficit and it runs the risk of rapid inflation and much higher interest rates when the economy improves.

Conclusion

• We continue to view the near term with caution.  While conditions existed for a substantial bear market rally, we have yet to see characteristics that suggest the beginning of a new bull market.  It’s been described as the best rally since the 1930s, but we are mindful that in 1931 there were three sharp rallies of 27%, 31%, and 20% before the market finally bottomed in 1932.

• During the bear market between the 2000 peak and Lowry’s major Buy-signal on 3/17/03, there was a 1-month, two 2-month, and a 6-month rally (altogether 383 Up days versus 399 Down days).  The stock market is trying to assess whether the Fed and other central banks as well as government stimulus will be successful in restoring investor confidence and avoiding a further meltdown.  So far the market decline reflects considerable skepticism and fear of substantial unintended consequences as we move into a more regulated, less leveraged financial system.

• We now expect a more extended recession, probably as severe as the 1979-82 downturn when government policies resulted in a 10.8% peak in unemployment.  Unemployment is already at 8.5%, that’s the highest since 1983 and the largest number of unemployed workers ever.  Many financial institutions face severe loan and capital problems and it remains unclear whether they will be willing and able to use their limited liquidity to help troubled clients.

• The Fed, the U.S. Treasury, and various government agencies are guaranteeing lending risks at the public’s expense and interfering with normal market adjustments.  Blanco Research tabulated all 34 plans/programs announced to date which at their maximums total $12.8 trillion or over $42,000 per person, almost $170,000 per family of four, an amount equivalent to a years annual output of the USA; three times more (adjusted for inflation) than the U.S. spent to fight WWII.  That amounts to an extraordinary debt burden on our country which will have dire long term consequences requiring a substantial increase in government control over our economy and our lives as well as endangering the dollars status as the world’s reserve currency.

• At the recent G-20 meeting, the Chinese, German, and Russian leaders were discussing alternatives to the dollar as the reserve currency, perhaps the establishment of a “super-sovereign reserve currency”.  With the huge increase in printing fiat dollars and running enormous deficits, we are jeopardizing the confidence of foreign lenders/investors.  If they decide to refrain from increasing their substantial US investments, we will suffer much higher interest rates and a substantial decline in the purchasing power of our dollar.  Already our largest creditor, China, is aggressively spending its dollars on copper, oil, gold and other tangible assets and entering into substantial swap/loan arrangements in Renminbi, their own currency, to eventually be used as an alternative reserve currency.

Chase Funds

• The Community Reinvestment Act mandated that banks lend to low income families that had little possibility of repaying their loans.  Even now the government continues to encourage people to borrow and spend when what they should be doing is getting out of debt.  Despite the government’s effort, in 4Q2008 total household credit market debt declined for the first time in over 50 years.  It is now taking over $6.00 of new debt-financing to increase GDP by just $1.00, compared to $1.68 in the 1970s.  We clearly cannot borrow and spend our way to prosperity.

• We continue to emphasize good quality more stable growth companies that are market leaders.  The economic slowdown and the transition from speculation to risk aversion which markets are experiencing favors good quality, reasonably priced, growth stocks.  If the current rally proves to be a sustainable rise, good quality equities should close the gap on the low quality, oversold stocks which have been the recent leaders; alternatively, if it turns out to be just a Bear market rally, our stocks should enjoy much better defensive qualities.

• As long term investors, we recognize that timing the market is very difficult.  One 35-year (420 month) study found that if you were out of the market just 5% of the time and missed the best 22 months, your 35-year gain would have been only 14% as much as the return on the S&P 500, even less than just holding T-bills.  Moreover, most investors who take money out of the market on a timely basis almost never get back in near the lows.  Recently a Spanish research firm found if you removed the 10 best days for the DJIA in each of the 1900-2008 years, two thirds of the cumulative gains were lost, but even more important if you missed the 10 worst days the gain on the Dow tripled, (See April ‘09 Shilling’s Insight, page 2).  That’s why we prefer to err on the conservative side.

Chase Investment Counsel Corp. manages over $4 billion for clients in 37 states.  The Chase Growth Fund (CHASX & CHAIX) and our Chase Mid-Cap Growth Fund (CHAMX) are managed by the same investment team, headed by David Scott, Chief Investment Officer, and Portfolio Manager Brian Lazorishak, that manages our large separate accounts.  As a moderate size firm, we have much more flexibility in buying and selling large and mid-cap stocks without a significant market impact.

To discourage even legal short term trading, which disrupts portfolio management and increases expenses for long-term investors, we impose a 2% fee on sales of shares in either fund held less than 60 days, computed on a first-in, first-out basis.  Such fees remain in the fund for the benefit of all shareholders.  The expense ratio on the Chase Growth Fund is 1.20% on an annualized basis for the Class N (CHASX) shares; 0.95% for Substantial Investor Class (CHAIX) shares.  On the Chase Mid-Cap Growth Fund, our expense ratio remains capped at 1.48% and the front-end sales charge was eliminated in the most recent Prospectus dated January 2009.  There are no annual Rule 12b-1 fees on either of our Funds.

We are pleased to announce that David B. Scott has been elected President of the Funds’ adviser, Chase Investment Counsel Corporation, replacing firm founder Derwood S. Chase, Jr.  Mr. Scott, formerly a Sr. Vice President, will continue in his role as a Director and as Chief Investment Officer with primary responsibility for overseeing the firm’s investment strategy and management of investment portfolios.  Mr. Chase was elected to the roles of Chairman and Chief Executive Officer (CEO), and will continue to be involved in formulating overall investment strategy.  He remains a member of the Board of Directors.  Jennifer King was elected Senior Vice President - Operations and Corporate Secretary.  The Directors believe that these changes are consistent with our executives’ current responsibilities and our future growth plans.  Our emphasis on effective portfolio management and client service remains unchanged.

We assure you that we will be working very hard to find, analyze and invest in relatively attractive, good quality stocks.  The officers and employees of Chase Investment Counsel Corporation appreciate your confidence and we look forward to a long investment relationship together.  Listed below are the 10 largest holdings of each fund as of March 31, 2009.

Chase Mid-Cap Growth Fund

Percentages represent market value as a percentage of total investments.

EXPENSE EXAMPLE at March 31, 2009 (Unaudited)

As a shareholder of a 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 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 (10/1/08 – 3/31/09).

Actual Expenses

The first line of the tables below provides information about actual account values and actual expenses, with actual net expenses being limited to 1.48% in the Chase Mid-Cap Growth Fund, per the advisory agreement. Although the Funds charge 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 Funds’ transfer agent. The example below includes, but is not limited to, management fees, shareholder servicing 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 tables below provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Funds’ 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 Funds 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 transaction costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second line of the tables 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 transaction costs were included, your costs would have been higher.

NOTES TO FINANCIAL STATEMENTS at March 31, 2009 (Unaudited)

NOTE 1 – ORGANIZATION

The Chase Growth Fund and the Chase Mid-Cap Growth Fund (each a “Fund” and collectively, the “Funds”) are each a series of shares of Advisors Series Trust (the “Trust”), which is registered under the Investment Company Act of 1940 (“1940 Act”), as amended, as an open-end management investment company. The Chase Growth Fund (the “Growth Fund”) is a diversified fund.  The investment objective of the Growth Fund is growth of capital, and it intends to achieve its objective by investing primarily in common stocks of domestic companies with a large market capitalization of $5 billion and above.  The Growth Fund commenced operations on December 2, 1997.  Prior to January 29, 2007, the shares of the Growth Fund had no specific designation.  As of that date, all of the then outstanding shares were redesignated as Class N Shares.  As part of its multiple class plan, the Growth Fund also offers Substantial Investor Class Shares, which commenced operations on January 29, 2007.  Because the fees and expenses vary between the Class N Shares and the Substantial Investor Class Shares, performance will vary with respect to each class.  Under normal conditions, the Substantial Investor Class Shares are expected to have lower expenses than the Class N Shares which will result in higher total returns.

The Chase Mid-Cap Growth Fund (the “Mid-Cap Fund”) is also a diversified fund.  The investment objective of the Mid-Cap Fund is to seek to achieve capital appreciation by primarily investing in common stocks or securities convertible into common stock of U.S. companies that have a mid-size market capitalization.  The advisor considers a mid-cap security to be one that has a market capitalization of between $1 billion and $18 billion.  Prior to January 28, 2009, the Mid-Cap Fund’s shares were designated as Class A Shares.  As of that date, all of the then outstanding shares were redesignated as Class N Shares.  The Mid-Cap Fund commenced operations on September 1, 2002.

The Growth Fund Class N Shares and the Mid-Cap Fund Class N Shares are offered through approved financial supermarkets, investment advisors and consultants, financial planners, broker-dealers and other investment professionals and their agents.  Substantial Investor Class Shares of the Growth Fund are offered to a limited category of investors, most notably to shareholders whose cumulative investment in the Growth Fund exceeds $1 million.  Substantial Investor Class Shares of the Growth Fund are typically not available through platforms, broker-dealers or other financial intermediaries.  They must be purchased directly through the Fund’s distributor, advisor or transfer agent.

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

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

28

Chase Funds

NOTES TO FINANCIAL STATEMENTS at March 31, 2009 (Unaudited), Continued

A. Security Valuation: The Funds’ 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 Global 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 Global Market System shall be valued at the most recent trade price.  Securities for which market quotations are not readily available or if the closing price does not represent fair value, are valued following procedures approved by the Board of Trustees.  These procedures consider many factors, including the type of security, size of holding, trading volume and news events.  Short-term investments are valued at amortized cost, which approximates market value.  Investments in other mutual funds are valued at their net asset value per share.

The Funds adopted the provisions of Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS 157”), effective with the beginning of the Funds’ fiscal year.  SFAS 157 establishes a hierarchy that prioritizes the inputs to valuation techniques giving the highest priority to readily available unadjusted quoted prices in active markets for identical assets (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements) when market prices are not readily available or reliable.  See note 6 – Summary of Fair Value Exposure for more information.

B. Federal Income Taxes: It is the Funds’ 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.

On July 13, 2006, the Financial Accounting Standards Board (“FASB”) released FASB Interpretation No. 48 “Accounting for Uncertainty in Income Taxes” (“FIN 48”).  FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented, and disclosed in the financial statements.  FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Funds’ tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority.  Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year.  Effective March 31, 2008, the Funds adopted FIN 48.  Management of the Funds reviewed the tax

29

Chase Funds

NOTES TO FINANCIAL STATEMENTS at March 31, 2009 (Unaudited), Continued

positions in the open tax years 2005 to 2008 for the Growth Fund and the Mid-Cap Fund.  Management of the Funds determined that the implementation of FIN 48 had no impact on either Fund’s net assets or results of operations.

C. Securities Transactions, Dividends and Distributions: Securities transactions are accounted for on the trade date. Realized gains and losses on securities sold are determined on the basis of identified cost.  Dividend income and distributions to shareholders are recorded on the ex-dividend date.   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 differs 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.  Investment income, expenses (other than those specific to the class of shares), and realized and unrealized gains and losses on investments are allocated to the separate classes of Growth Fund shares based upon their relative net assets on the date income is earned or expensed and realized and unrealized gains and losses are incurred.

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. Redemption Fees: The Funds charge a 2% redemption fee to shareholders who redeem shares held for 60 days or less.  Such fees are retained by the Fund and accounted for as an addition to paid-in capital.

F. REITs: The Funds can make certain investments in real estate investment trusts (“REITs”) which pay dividends to their shareholders based upon funds available from operations.  It is quite common for these dividends to exceed the REITs’ taxable earnings and profits resulting in the excess portion of such dividends being designated as a return of capital.  Each Fund intends to include the gross dividends from such REITs in its annual distributions to its shareholders and, accordingly, a portion of the Fund’s distributions may also be designated as a return of capital.

G. 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.

H. New Accounting Pronouncement: In March 2008, Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS 161”) was issued and is effective for fiscal years beginning after November 15, 2008.  SFAS 161 is intended to improve financial reporting for derivative instruments by requiring enhanced disclosure that enables investors to understand how and why an entity uses derivatives, how derivatives are accounted for, and how derivative instruments affect an entity’s results of operations and financial position.  Management is currently evaluating the implications of SFAS 161.  The impact on the Funds’ financial statement disclosures, if any, is currently being assessed.

NOTE 3 – INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES

For the six months ended March 31, 2009, Chase Investment Counsel Corporation (the “Advisor”) provided the Funds with investment management services under an Investment Advisory Agreement. The Advisor furnished all investment advice, office space, facilities, and provides most of the personnel needed by the Funds. As compensation for its services, the Advisor is entitled to a monthly fee at the annual rate of 0.75% based upon the average daily net assets of each Fund. For the six months ended March 31, 2009, the Growth Fund and the Mid-Cap Fund incurred $1,723,684 and $81,260 in advisory fees, respectively.

Each Fund is responsible for its own operating expenses.  The Advisor has agreed to reduce fees payable to it by the Mid-Cap Fund and to pay the Fund’s operating expenses to the extent necessary to limit the Mid-Cap Fund’s aggregate annual operating expenses to 1.48% of average daily net assets.  Any such reductions made by the Advisor in its fees or payment of expenses which are the Mid-Cap 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 the Fund’s expenses. The Advisor is permitted to be reimbursed for fee reductions and expense payments made in the previous three fiscal years in the Mid-Cap Fund.  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 six months ended March 31, 2009, the Advisor reduced its fees and absorbed Fund expenses in the amount of $18,530 in the Mid-Cap Fund.  Cumulative expenses subject to recapture pursuant to the aforementioned conditions amounted to $100,286 at March 31, 2009 in the Mid-Cap Fund.  Cumulative expenses subject to recapture expire as follows:

NOTE 4 – SHAREHOLDER SERVICING FEE

The Growth Fund and the Mid-Cap Fund have entered into a Shareholder Servicing Agreement (the “Agreement”) with the Advisor, under which the Growth Fund Class N Shares and the Mid-Cap Fund Class N Shares may pay servicing fees at an annual rate of 0.25% of the average daily net assets of each Fund’s respective class. Payments to the Advisor under the Agreement may reimburse the Advisor for payments it makes to selected brokers, dealers and administrators which have entered into Service Agreements with the Advisor for services provided to shareholders of the Funds.  The services provided by such intermediaries are primarily designed to assist shareholders of the Funds and include the furnishing of office space and equipment, telephone facilities, personnel and

32

Chase Funds

NOTES TO FINANCIAL STATEMENTS at March 31, 2009 (Unaudited), Continued

assistance to the Funds in servicing such shareholders.  Services provided by such intermediaries also include the provision of support services to the Funds and include establishing and maintaining shareholders’ accounts and record processing, purchase and redemption transactions, answering routine client inquiries regarding the Funds, and providing such other personal services to shareholders as the Funds may reasonably request.  For the six months ended March 31, 2009, the Growth Fund Class N Shares and the Mid-Cap Fund Class N Shares incurred shareholder servicing fees of $442,260 and $27,086 under the Agreement, respectively.

NOTE 6 – SUMMARY OF FAIR VALUE EXPOSURE

Various inputs are used in determining the value of the Funds’ investments.  These inputs are summarized in the three broad levels listed below:

Level 1 –	Quoted prices in active markets for identical securities.
Level 2 –	Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3 –	Significant unobservable inputs (including the Funds own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used to value the Funds’ securities as of March 31, 2009:

At a meeting held on December 11, 2008, the Board, including the persons who are Independent Trustees as defined under the Investment Company Act, considered and approved the continuance of the Advisory Agreements for the Chase Growth Fund and the Chase Mid-Cap Growth Fund with the Advisor for another annual term.  Prior to this meeting, the Board received and reviewed substantial information regarding the Funds, the Advisor and the services provided by the Advisor to the Funds under the Advisory Agreements.  This information, together with the information provided to the Board throughout the course of the year, formed the primary (but not exclusive) basis for the Board’s determinations.  Below is a summary of the factors considered by the Board and the conclusions that formed the basis for the Board’s continuance of the Advisory Agreements:

1. THE NATURE, EXTENT AND QUALITY OF THE SERVICES PROVIDED AND TO BE PROVIDED BY THE ADVISOR UNDER THE ADVISORY AGREEMENTS.  The Board considered the Advisor’s specific responsibilities in all aspects of day-to-day investment management of the Funds. The Board considered the qualifications, experience and responsibilities of the portfolio managers, as well as the responsibilities of other key personnel of the Advisor involved in the day-to-day activities of the Funds. The Board also considered the resources and compliance structure of the Advisor, including information regarding its compliance program, its chief compliance officer and the Advisor’s compliance record, and the Advisor’s business continuity plan. The Board also considered the prior relationship between the Advisor and the Trust, as well as the Board’s knowledge of the Advisor’s operations, and noted that during the course of the prior year they had met with the Advisor in person to discuss various marketing and compliance topics.  The Board concluded that the Advisor had the quality and depth of personnel, resources, investment methods and compliance policies and procedures essential to performing its duties under the Advisory Agreements and that the nature, overall quality, cost and extent of such management services are satisfactory and reliable.

2. THE FUNDS’ HISTORICAL YEAR-TO-DATE PERFORMANCE AND THE OVERALL PERFORMANCE OF THE ADVISOR.  In assessing the quality of the portfolio management delivered by the Advisor, the Board reviewed the short-term and long-term performance of the Funds as of October 31, 2008 on both an absolute basis, and in comparison to its peer funds as classified by Lipper.

Chase Growth Fund:  The Board noted that the Growth Fund’s performance was above its peer group median and averages for all relevant periods.  The Board particularly noted the Fund’s first quartile performance ranking for all relevant periods.

Chase Mid-Cap Growth Fund:  The Board noted that the Mid-Cap Growth Fund’s performance was above its peer group median and averages for the year-to-date, one-year, and five-year returns and was above its peer group median for the three-year returns.  The Board particularly noted the Fund’s first quartile performance ranking for the year-to-date, one-year and five-year periods.

3. THE COSTS OF THE SERVICES TO BE PROVIDED BY THE ADVISOR AND THE STRUCTURE OF THE ADVISOR’S FEE UNDER THE ADVISORY AGREEMENTS.  In considering the advisory fee and total fees and expenses of each Fund, the Board reviewed comparisons to its peer funds and separate accounts for other types of clients advised by the Advisor, as well as all expense waivers and reimbursements.

Chase Growth Fund:The Board noted that the Growth Fund’s total expense ratio was lower than the median and average of its peer group.  The Board also noted that the contractual advisory fee was above the median and average of its peer group though it was in line with the fees charged by the Advisor to its other investment management clients at minimum investment levels.  As a result, the Trustees noted that the Fund’s expenses and advisory fee were not outside the range of its peer group.

Chase Mid-Cap Growth Fund:The Board noted that the Advisor had contractually agreed to maintain an Expense Cap for the Mid-Cap Growth Fund of 1.48%.  Additionally, the Board noted that the Fund’s total expense ratio and contractual advisory fee were slightly higher than the average of its peer group, and the contractual advisory fee was equal to the median of its peer group.  The Board further noted that the contractual advisory fee was in line with the fees charged by the Advisor to its other investment management clients at minimum investment levels.  The Board also considered that after advisory fee waivers and the payment of Fund expenses necessary to maintain the Expense Cap, the net advisory fees received by the Advisor from the Fund during the most recent fiscal period was below the peer group median and average.  As a result, the Trustees noted that the Fund’s expenses and advisory fee were not outside the range of its peer group.

4. ECONOMIES OF SCALE.  The Board also considered that economies of scale were being achieved with the Growth Fund and that economies of scale would be expected to be realized as the assets of the Mid-Cap Growth Fund grow.  The Board noted that the Advisor has contractually agreed to reduce its advisory fees or pay for Mid-Cap Growth Fund expenses so that the Fund does not exceed a specified expense limitation.  The Board determined that they would discuss advisory fee breakpoints on the Growth Fund with the Advisor in the future.  The Board concluded that there were no effective economies of scale

to be shared with the Mid-Cap Growth Fund at current asset levels, but considered revisiting this issue in the future as circumstances changed and asset levels increased.

5. THE PROFITS TO BE REALIZED BY THE ADVISOR AND ITS AFFILIATES FROM THEIR RELATIONSHIP WITH THE FUNDS.  The Board reviewed the Advisor’s financial information and took into account both the direct benefits and the indirect benefits to the Advisor from advising the Funds. The Board considered the profitability to the Advisor from its relationship with the Funds and considered any additional benefits derived by the Advisor from its relationship with the Funds, particularly benefits received in exchange for “soft dollars.”  After such review, the Board determined that additional information regarding the profitability to the Advisor with respect to the Advisory Agreements was appropriate, but that given the information presented, the profitability to the Advisor with respect to the Advisory Agreements did not appear to be excessive, and that the Advisor had maintained adequate profit levels to support the services it provides to the Funds.

No single factor was determinative of the Board’s decision to approve the continuance of the Advisory Agreements for the Chase Growth Fund and the Chase Mid-Cap Growth Fund, but rather the Board based its determination on the total mix of information available to them.  Based on a consideration of all the factors in their totality, the Board determined that the advisory arrangement with the Advisor, including the advisory fees, were fair and reasonable.  The Board therefore determined that the continuance of the Advisory Agreements for the Chase Growth Fund and the Chase Mid-Cap Growth Fund would be in the best interest of each Fund and its shareholders.
