Congress All Cap Opportunity Fund (Prospectus Summary) | Congress All Cap Opportunity Fund

Congress All Cap Opportunity Fund

Investment Objective

The Congress All Cap Opportunity Fund (the "All Cap Opportunity Fund") seeks
long-term capital appreciation.

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 All Cap Opportunity Fund.

Shareholder Fees (Fees paid directly from your investment)

Shareholder Fees Congress All Cap Opportunity Fund	Retail Class	Institutional Class
Redemption Fee (as a percentage of amount redeemed within 90 days of purchase)	1.00%	1.00%

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

Annual Fund Operating Expenses Congress All Cap Opportunity Fund		Retail Class	Institutional Class
Management Fees		0.60%	0.60%
Distribution and Service (12b-1) Fees		0.25%	none
Other Expenses	[1]	1.62%	1.62%
Total Annual Fund Operating Expenses		2.47%	2.22%
Fee Waiver and/or Expense Reimbursement		(1.47%)	(1.47%)
Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement	[2]	1.00%	0.75%

Example

The Example below is intended to help you compare the cost of investing in the
All Cap Opportunity Fund with the cost of investing in other mutual funds. This
Example assumes that you invest $10,000 in the All Cap Opportunity 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% annual return
each year and that the Fund's operating expenses remain the same (taking into
account the Expense Caps for the first two years).

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

Expense Example Congress All Cap Opportunity Fund (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years
Retail Class	102	629
Institutional Class	77	552

Portfolio Turnover

The Fund pays transaction costs, such as commissions, 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
annual fund operating expenses or in the example, affect the Fund's performance.

Principal Investment Strategies

The All Cap Opportunity Fund seeks to achieve its objective by investing at
least 80% of its net assets (plus borrowings for investment purposes) in equity
securities. The Fund's investment premise is that market inefficiencies exist
between fixed income and equity valuations which, if properly identified, can
lead to investment opportunities which can be exploited. An analysis of a
company's entire capital structure can provide a unique insight into a purchase
or sell decision of a particular stock. Congress Asset Management Company, LLP
("the Advisor") seeks to uncover these inefficiencies for the Fund, and identify
equity investment opportunities which may provide the opportunity for long term
capital appreciation. The Fund invests primarily in publicly traded stocks of
U.S. companies, irrespective of market capitalization size or industry sector.
The All Cap Opportunity Fund may invest up to 20% of its total assets in
investment-grade debt securities, such as commercial paper or corporate debt
securities. Additionally, the Fund may invest up to 20% of its total assets
in the securities of foreign issuers, including American Depositary Receipts
("ADRs"). The All Cap Opportunity Fund is "opportunistic" and may focus its
investments in securities and industries that the Advisor believes are poised
to experience earnings growth. The Advisor may sell a security for a number
of reasons including, but not limited to a determination that the security no
longer meets its investment criteria or if a new security is judged to be more
attractive than a current holding.

Principal Risks of Investing in the All Cap Opportunity Fund

There is a risk that you could lose all or a portion of your investment in the
Fund. The principal risks of an investment in the Fund include:

·  Equity Market Risk: Common stocks are susceptible to general stock market     
   fluctuations and to volatile increases and decreases in value. The stock      
   market may experience declines or stocks in a Fund's portfolio may not        
   increase their earnings at the rate anticipated.

·  General Market Risk: The market price of a security may fluctuate, sometimes  
   rapidly and unpredictably. These fluctuations may cause a security to be worth
   less than its cost when originally purchased or less than it was worth at an  
   earlier time.

·  Management Risk: The portfolio manager's ability to identify valuation        
   inefficiencies and its judgment as to the growth potential or value of a stock
   proves to be wrong.

·  Small and Medium Company Risk: Securities of small and medium cap companies   
   may possess comparatively greater price volatility and less liquidity than the
   securities of companies that have larger market capitalizations and/or that   
   are traded on major stock exchanges.

·  Foreign Investment Risk: Foreign securities, including ADRs, involve additional
   risks, including currency-rate fluctuations, political and economic instability,
   differences in financial reporting standards, and less-strict regulation of
   securities markets.

·  Debt/Fixed Income Securities Risk: An increase in interest rates typically    
   causes a fall in the value of the debt securities in which the Fund may       
   invest. The value of your investment in the Fund may change in response to    
   changes in the credit ratings of the Fund's portfolio of debt securities.

·  Regulatory Risk: Changes in government regulations may adversely affect the   
   value of a security.

·  New Fund Risk: The Fund is new with no operating history, and there can be no
   assurance that the Fund will grow to or maintain an economically viable size.

Performance Information

Because the Fund recently commenced operations, it does not have a full calendar
year of performance to compare against a broad measure of market performance.
Accordingly, performance information is not available. Performance information
will be shown below after the Fund has been in operation for one calendar year.
At that time, the performance information will provide some indication of the
risks of investing in the Fund by comparing it against a broad measure of market
performance. Updated performance information will also be available on the Fund's
website at www.congressasset.com/funds or by calling the Fund's toll-free at
1-888-688-1299.

[1] Other expenses are based on estimated amounts for the current fiscal year.

[2] Congress Asset Management Company, LLP (the "Advisor") has contractually agreed to reduce its fees and/or pay Fund expenses (excluding the expenses associated with the Fund's investment in other investment companies referred to as "Acquired Fund Fees and Expenses," interest expense in connection with investment activities, taxes and extraordinary expenses) in order to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the Fund to 1.00% of the Fund's Retail Class shares' and 0.75% for the Institutional Class shares' average net assets, (the "Expense Caps"). The Expense Caps are indefinite, and will remain in effect until at least October 31, 2014. The Agreement may be terminated at any time by the Board of Trustees upon 60 days' written notice to the Advisor, or by the Advisor with the consent of the Board.

Portfolio Turnover

The Mid Cap Fund pays transaction costs, such as commissions, 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 annual fund operating expenses or in the example, affect the Fund's performance.

Principal Investment Strategies

The Mid Cap Fund seeks to achieve its investment objective by investing at least
80% of its net assets (plus any borrowings for investment purposes) in equity
securities of mid-capitalization companies. The Fund may invest any portion of
the remaining 20% of its net assets in equity securities of small-capitalization
and large-capitalization companies. The Fund invests primarily in publicly
traded stocks of U.S. companies which the Advisor considers to have a mid-size
market capitalization. The Fund considers a company to be a mid-cap company if
it has a market capitalization, at the time of purchase, between $1 billion and
$5 billion. The Fund may also invest from time to time in equity securities of
large-capitalization companies (i.e., those with capitalizations over $5 billion)
and equity securities of small-capitalization companies (i.e., those with
capitalizations of less than $1 billion). The Fund may invest up to 10% of its
total assets in the securities of foreign issuers, including American Depositary
Receipts ("ADRs"). The Fund invests in companies that Congress Asset Management
Company, LLP (the "Advisor") believes are experiencing or will experience earnings
growth. The Advisor employs a "bottom-up" approach to research and stock selection,
which means that the Advisor bases its investments on a company's future prospects
and not on any significant economic or market cycle. The Advisor also uses a
growth-style approach to selecting securities with a focus on high quality companies.
The Advisor's fundamental approach emphasizes earnings growth and free cash flow.
The Advisor may sell a security for a number of reasons including, but not limited
to, if a determination is made that the security no longer meets its investment
criteria or if a new security is judged more attractive than a current holding.

Principal Risks of Investing in the Fund

There is a risk that you could lose all or a portion of your investment in the
Fund. The principal risks of an investment in the Fund include:

·  Equity Market Risk: Common stocks are susceptible to general stock market     
   fluctuations and to volatile increases and decreases in value. The stock      
   market may experience declines or stocks in the Fund's portfolio may not      
   increase their earnings at the rate anticipated.

·  General Market Risk: The market price of a security may fluctuate, sometimes  
   rapidly and unpredictably. These fluctuations may cause a security to be worth
   less than its cost when originally purchased or less than it was worth at an  
   earlier time.

·  Growth Style Investment Risk: Growth stocks fall out of favor with investors.

·  Management Risk: The portfolio manager's judgment as to the growth potential  
   or value of a stock proves to be wrong.

·  Small and Medium Company Risk: Securities of small and medium cap companies   
   may possess comparatively greater price volatility and less liquidity than the
   securities of companies that have larger market capitalizations and/or that   
   are traded on major stock exchanges.

·  Foreign Markets Risk: Foreign securities, including ADRs, involve additional  
   risks, including currency-rate fluctuations, political and economic instability,
   differences in financial reporting standards, and less-strict regulation of
   securities markets.

·  Regulatory Risk: Changes in government regulations may adversely affect the   
   value of a security.

These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Mid Cap Fund seeks to achieve its investment objective by investing at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of mid-capitalization companies. The Fund may invest any portion of the remaining 20% of its net assets in equity securities of small-capitalization and large-capitalization companies. The Fund invests primarily in publicly traded stocks of U.S. companies which the Advisor considers to have a mid-size market capitalization. The Fund considers a company to be a mid-cap company if it has a market capitalization, at the time of purchase, between $1 billion and $5 billion. The Fund may also invest from time to time in equity securities of large-capitalization companies (i.e., those with capitalizations over $5 billion) and equity securities of small-capitalization companies (i.e., those with capitalizations of less than $1 billion). The Fund may invest up to 10% of its total assets in the securities of foreign issuers, including American Depositary Receipts ("ADRs"). The Fund invests in companies that Congress Asset Management Company, LLP (the "Advisor") believes are experiencing or will experience earnings growth. The Advisor employs a "bottom-up" approach to research and stock selection, which means that the Advisor bases its investments on a company's future prospects and not on any significant economic or market cycle. The Advisor also uses a growth-style approach to selecting securities with a focus on high quality companies. The Advisor's fundamental approach emphasizes earnings growth and free cash flow. The Advisor may sell a security for a number of reasons including, but not limited to, if a determination is made that the security no longer meets its investment criteria or if a new security is judged more attractive than a current holding.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	There is a risk that you could lose all or a portion of your investment in the Fund. The principal risks of an investment in the Fund include: ·  Equity Market Risk: Common stocks are susceptible to general stock market         fluctuations and to volatile increases and decreases in value. The stock          market may experience declines or stocks in the Fund's portfolio may not          increase their earnings at the rate anticipated. ·  General Market Risk: The market price of a security may fluctuate, sometimes      rapidly and unpredictably. These fluctuations may cause a security to be worth    less than its cost when originally purchased or less than it was worth at an      earlier time. ·  Growth Style Investment Risk: Growth stocks fall out of favor with investors. ·  Management Risk: The portfolio manager's judgment as to the growth potential      or value of a stock proves to be wrong. ·  Small and Medium Company Risk: Securities of small and medium cap companies       may possess comparatively greater price volatility and less liquidity than the    securities of companies that have larger market capitalizations and/or that       are traded on major stock exchanges. ·  Foreign Markets Risk: Foreign securities, including ADRs, involve additional      risks, including currency-rate fluctuations, political and economic instability,    differences in financial reporting standards, and less-strict regulation of    securities markets. ·  Regulatory Risk: Changes in government regulations may adversely affect the       value of a security. ·  New Fund Risk: The Fund is new with no operating history, and there can be no    assurance that the Fund will grow to or maintain an economically viable size.
