M.D. Sass 1-3 Year Duration U.S. Agency Bond Fund (Prospectus Summary) | M.D. Sass 1-3 Year Duration U.S. Agency Bond Fund

M.D. Sass 1-3 Year Duration U.S. Agency Bond Fund

Investment Objective

The M.D. Sass 1-3 Year Duration U.S. Agency Bond Fund (the "Fund") seeks to
achieve a high and stable rate of total return, when and as opportunities are
available in the context of preserving capital in adverse markets.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund.

Shareholder Fees (fees paid directly from your investment) None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses M.D. Sass 1-3 Year Duration U.S. Agency Bond Fund	Institutional Class Shares	Retail Class Shares
Management Fees	0.30%	0.30%
Distribution and Service (12b-1) Fees	none	0.25%
Other Expenses	0.33%	0.33%
Total Annual Fund Operating Expenses	0.63%	0.88%

Example

This Example is intended to help you compare the costs of investing in the Fund
with the cost of investing in other mutual funds. The Example assumes that you
invest $10,000 in the Fund for the time periods indicated and then redeem all of
your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example M.D. Sass 1-3 Year Duration U.S. Agency Bond Fund (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Institutional Class Shares	64	202	351	786
Retail Class Shares	90	281	488	1,084

Portfolio Turnover

The Fund pays transaction costs, such as commissions and/or bid/ask spreads,
when it buys and sells securities (or "turns over" its portfolio). A higher
portfolio turnover rate may indicate higher transaction costs and may result in
higher taxes when Fund shares are held in a taxable account. These costs, which
are not reflected in the Total Annual Fund Operating Expenses or in the Example,
affect the Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 87.78% of the average value of its portfolio.

Principal Investment Strategies

To achieve its investment objective, the Fund invests at least 95% of its assets
in U.S. Government and agency mortgage-backed securities ("MBS") and other
securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities (including Ginnie Mae, Fannie Mae and Freddie Mac, as defined
below), and collateralized mortgage obligations ("CMOs"), backed by U.S.
Government and agency MBS. Some of the Fund's investments may be backed by the
full faith and credit of the U.S. Government, while others may be supported only
by the discretionary authority of the U.S. Government or only by the credit of
the issuing agency or instrumentality.
  
Under normal market conditions, the target dollar-weighted average effective
duration for the Fund is expected to range between 1 and 3 years. Duration is a
measure of a fixed income security's price sensitivity to changes in interest
rates. Duration takes into account a security's cash flows over time, including
the possibility that a security might be prepaid by the issuer or redeemed by
the holder prior to its stated maturity date. In contrast, maturity measures
only the time until final payment is due. The duration of the Fund's portfolio
is expressed in years and measures the portfolio's change in value for changes
in interest rates. The Fund may also invest in U.S. Treasury bills. The
securities held by the Fund may be fixed or variable rate obligations. The Fund
may also purchase securities on a when-issued or delayed-delivery basis.

To construct the Fund's investment portfolio, the Adviser utilizes a process
based on rigorous quantitative tests. These tests include projecting underlying
mortgage prepayment rates under a variety of interest rate scenarios and
demographic trends, with regard to any given security's sensitivity to cash flow
risk. The nature of such testing is to measure homeowner refinancing/prepayment
behavior, relative to mortgage rate changes, and other factors influencing such
behavior. The Adviser's process is primarily structured to create value through
intensive (i.e. bottom-up) security selection, portfolio construction and
relative value trading. Top-down macro issues and factors are incorporated into
the process when considered by the Adviser to be appropriate. The Adviser may
sell a security if its value becomes unattractive, such as when its fundamentals
deteriorate, or when other investment opportunities exist that may have more
attractive yields.

Principal Risks

Before investing in the Fund, you should carefully consider your own investment
goals, the amount of time you are willing to leave your money invested, and the
amount of risk you are willing to take. Remember, in addition to possibly not
achieving your investment goals, you could lose all or a portion of your
investment in the Fund over long or even short periods of time. The principal
risks of investing in the Fund are:

·  General Market Risk. The risk that certain securities selected for the Fund's
   portfolio may be worth less than the price originally paid for them, or less  
   than they were worth at an earlier time.                                      

·  Management Risk. The risk that the Adviser's judgments about the              
   attractiveness, value and potential appreciation of the Fund's investments
   may prove to be incorrect and that the investment strategies employed by the      
   Adviser in selecting investments for the Fund may not result in an increase in
   the value of your investment or in overall performance equal to other similar
   investment vehicles having similar investment strategies.                     

·  Fixed Income Securities Risks. Interest rates may go up resulting in a        
   decrease in the value of the fixed income securities held by the Fund. Fixed  
   income securities subject to prepayment can offer less potential for gains    
   during a declining interest rate environment and similar or greater potential
   for loss in a rising interest rate environment. Limited trading opportunities
   for certain fixed income securities may make it more difficult to sell or buy
   a security at a favorable price or time.                                      

·  Issuer Risk. Securities issued by U.S. Government agencies and instrumentalities
   have different levels of U.S. Government credit support. Some are backed by
   the full faith and credit of the U.S. Government, while others are supported
   by only the discretionary authority of the U.S. Government or only by the
   credit of the agency or instrumentality. No assurance can be given that the
   U.S. Government will provide financial support to U.S. Government-sponsored
   instrumentalities because they are not obligated to do so by law. Guarantees
   of timely prepayment of principal and interest do not assure that the market
   prices and yields of the securities are guaranteed nor do they guarantee the
   net asset value or performance of the Fund, which will vary with changes in
   interest rates, the Adviser's success and other market conditions.                                                            

·  Mortgage-Backed Securities Risks:

   ·  Prepayment Risk of Mortgage-Backed Securities. In times of declining interest
      rates, the Fund's higher yielding securities will be prepaid and the Fund will
      have to replace them with securities having a lower yield.                    

   ·  Extension Risk of Mortgage-Backed Securities. In times of rising interest     
      rates, mortgage prepayments will slow causing portfolio securities considered
      short or intermediate term to be long-term securities which fluctuate more    
      widely in response to changes in interest rates than shorter term securities.

·  Liquidity Risk. The risk that a particular investment may be difficult to     
   purchase or sell and that the Fund may be unable to sell illiquid securities  
   at an advantageous time or price or purchase securities in an amount          
   sufficient to achieve its desired level of exposure.                          

·  When-Issued Securities Risk. The risk that the price or yield obtained in a   
   when-issued transaction may be less favorable than the price or yield         
   available in the market when the securities delivery takes place, or that     
   failure of a party to a transaction to consummate the trade may result in a   
   loss to the Fund or missing an opportunity to obtain a price considered       
   advantageous.
