The Fund will invest its assets in both value and growth stocks, as well as dividend-paying and non-dividend-paying stocks.

Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Multi-Cap Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Losing all or a portion of your investment is a risk of investing in the Multi-Cap Fund. The following principal risks could affect the value of your investment: ·   Equity Risk. Stock prices may fluctuate widely over short or even extended        periods in response to company, market, or economic news. Stock markets also     tend to move in cycles, with periods of rising stock prices and periods of        falling stock prices.    ·   ETF and Mutual Fund Risk. ETFs are typically open-end investment companies        that are bought and sold on a national securities exchange. Investment            companies (mutual funds) and ETFs have management fees that are part of their     costs, and the Multi-Cap Fund will indirectly bear its proportionate share of     these costs.                                          ·   Foreign and Emerging Market Securities Risk. The Multi-Cap Fund may invest in     foreign securities which are subject to special risks. Foreign securities can     be more volatile than domestic (U.S.) securities. Securities markets of other     countries are generally smaller than U.S. securities markets. Many foreign        securities may be less liquid and more volatile than U.S. securities, which       could affect the Fund's investments. These risks are enhanced in emerging         markets. ·   Management Risk. Management risk means that your investment in the Multi-Cap     Fund varies with the success and failure of the Advisor's investment              strategies and the Advisor's research, analysis and determination of              portfolio securities. ·   Market and Issuer Risk. The risks that could affect the value of the              Multi-Cap Fund's shares and the total return on your investment include the       possibility that the securities held by the Fund will fluctuate as a result       of the movement of the overall stock market or of the value of the individual     securities held by the Fund. The value of securities held by the Fund may         also experience sudden, unpredictable drops in value or long periods of           decline in value due to reasons directly related to the issuer, including         management performance, financial leverage, and reduced demand for the            issuer's goods and services. ·   Options Risk. Options on securities may be subject to greater fluctuations in     value than an investment in the underlying securities. Purchasing and writing     put and call options are highly specialized activities and entail greater         than ordinary investment risks. ·   Small and Medium Companies Risk. Investing in securities of small and medium     capitalization companies may involve greater volatility than investing in         larger and more established companies because small and medium capitalization     companies can be subject to more abrupt or erratic share price changes than       larger, more established companies. The Multi-Cap Fund may be appropriate for investors who: ·   Have a long-term investment horizon; ·   Want to add an investment with potential for capital appreciation to              diversify their investment portfolio; and ·   Can accept the greater risks of investing in a portfolio with equity holdings.

The Expense Caps will remain in effect through at least October 27, 2013, and may be terminated only by the Trust's Board of Trustees (the "Board").

Example.

This Example is intended to help you compare the cost of investing in the Multi-Cap
Fund with the cost of investing in other mutual funds. The Example assumes that you
invest $10,000 in the Multi-Cap Fund for the time periods indicated and then either
redeem or do not 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 Multi-Cap
Fund's operating expenses remain the same (taking into account the Expense Caps
only in the first year). Although your actual costs may be higher or lower, based
on these assumptions your costs would be:

If you redeem your shares at the end of the period:

Class A	611	920	1,250	2,182
Class C	193	674	1,181	2,577

Portfolio Turnover.

The Multi-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 Multi-Cap Fund shares are held in a taxable account. These costs,
which are not reflected in the Annual Fund Operating Expenses or in the
Example, affect the Multi-Cap Fund's performance. During the most recent
fiscal year, the Multi-Cap Fund's portfolio turnover rate was 13.95% of the
average value of its portfolio.

Principal Investment Strategies of the Multi-Cap Fund

Under normal market conditions, the Multi-Cap Fund invests at least 80% of its
net assets (including any borrowings for investment purposes) in equity
securities across a wide range of market capitalizations and investment styles
with attractive fundamental characteristics. The Fund looks for companies with
reasonable valuations, prudent debt levels, cash flow generation, attractive
growth characteristics and solid balance sheets. The Fund will invest its assets
in both value and growth stocks, as well as dividend-paying and non-dividend-paying
stocks. The Fund will seek to achieve its investment objective primarily through
stock selection, with less emphasis on sector weightings. As a result, the Fund
expects to only occasionally make modest sector changes, preferring to
differentiate performance by relative movement in individual stocks than in
sectors or industries .

The Multi-Cap Fund may seek to enhance returns through the use of other investment
strategies such as options (for hedging purposes), foreign securities (which may
include American Depositary Receipts ("ADRs"), dollar-denominated foreign
securities, or direct investment in foreign securities, including emerging markets),
and other investment companies (including exchange-traded funds ("ETFs")). The Fund
may invest up to 20% of its net assets in foreign securities. The Fund may invest
up to 20% of its net assets in put and call options.

The Advisor may sell a position if the fundamentals have deteriorated, catalysts
fail to develop, or a stock exceeds fair valuation. The Advisor may also sell a
position if a better alternative becomes available.

At the discretion of the Advisor, the Multi-Cap Fund may invest its assets in
cash, cash equivalents, and high-quality, short-term debt securities and money
market instruments for temporary defensive purposes in response to adverse
market, economic or political conditions.

Principal Risks of Investing in the Multi-Cap Fund

Losing all or a portion of your investment is a risk of investing in the
Multi-Cap Fund. The following principal risks could affect the value of your
investment:

·   Equity Risk. Stock prices may fluctuate widely over short or even extended   
    periods in response to company, market, or economic news. Stock markets also
    tend to move in cycles, with periods of rising stock prices and periods of   
    falling stock prices.
  
·   ETF and Mutual Fund Risk. ETFs are typically open-end investment companies   
    that are bought and sold on a national securities exchange. Investment       
    companies (mutual funds) and ETFs have management fees that are part of their
    costs, and the Multi-Cap Fund will indirectly bear its proportionate share of
    these costs.
                                        
·   Foreign and Emerging Market Securities Risk. The Multi-Cap Fund may invest in
    foreign securities which are subject to special risks. Foreign securities can
    be more volatile than domestic (U.S.) securities. Securities markets of other
    countries are generally smaller than U.S. securities markets. Many foreign   
    securities may be less liquid and more volatile than U.S. securities, which  
    could affect the Fund's investments. These risks are enhanced in emerging    
    markets.

·   Management Risk. Management risk means that your investment in the Multi-Cap
    Fund varies with the success and failure of the Advisor's investment         
    strategies and the Advisor's research, analysis and determination of         
    portfolio securities.

·   Market and Issuer Risk. The risks that could affect the value of the         
    Multi-Cap Fund's shares and the total return on your investment include the  
    possibility that the securities held by the Fund will fluctuate as a result  
    of the movement of the overall stock market or of the value of the individual
    securities held by the Fund. The value of securities held by the Fund may    
    also experience sudden, unpredictable drops in value or long periods of      
    decline in value due to reasons directly related to the issuer, including    
    management performance, financial leverage, and reduced demand for the       
    issuer's goods and services.

·   Options Risk. Options on securities may be subject to greater fluctuations in
    value than an investment in the underlying securities. Purchasing and writing
    put and call options are highly specialized activities and entail greater    
    than ordinary investment risks.

·   Small and Medium Companies Risk. Investing in securities of small and medium
    capitalization companies may involve greater volatility than investing in    
    larger and more established companies because small and medium capitalization
    companies can be subject to more abrupt or erratic share price changes than  
    larger, more established companies.

The Multi-Cap Fund may be appropriate for investors who:

·   Have a long-term investment horizon;

·   Want to add an investment with potential for capital appreciation to         
    diversify their investment portfolio; and

·   Can accept the greater risks of investing in a portfolio with equity holdings.

Performance

The following information provides some indication of the risks of investing in
the Multi-Cap Fund by showing changes in the Fund's Class A shares' performance
from year to year and by showing how the Fund's average annual returns for 1
year and since inception compare with those of a broad measure of market
performance. Sales loads are not reflected in the bar chart; if these amounts
were reflected, returns would be less than those shown. The Fund's past
performance, before and after taxes, is not necessarily an indication of how the
Fund will perform in the future. Updated performance information is available on
the Fund's website at www.davidsonmutualfunds.com or by calling the Fund
toll-free at 1-877-332-0529.

The after-tax returns were calculated using the historical highest individual
federal marginal income tax rates and do not reflect the impact of state and
local taxes. Actual after-tax returns depend on an investor's tax situation
and may differ from those shown, and after-tax returns are not relevant to
investors who hold shares of the Fund through tax-deferred arrangements, such
as 401(k) plans or individual retirement accounts ("IRAs").

The return after taxes on distributions and sale of Fund shares is higher than
other return figures when a capital loss occurs upon the redemption of Fund
shares.

(the "Advisor") has contractually agreed to waive all or a portion of its management fees and pay expenses of the Multi-Cap Fund to ensure that Net Annual Fund Operating Expenses (excluding acquired fund fees and expenses ("AFFE"), interest, taxes and extraordinary expenses) do not exceed 1.15% of average daily net assets of the Multi-Cap Fund's Class A shares and 1.90% of average daily net assets of the Multi-Cap Fund's Class C shares (the "Expense Caps"). The Expense Caps will remain in effect through at least October 27, 2013, and may be terminated only by the Trust's Board of Trustees (the "Board"). The Advisor may request recoupment of previously waived fees and paid expenses from the Multi-Cap Fund for three years from the date they were waived or paid, subject to the Expense Caps.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Small/Mid Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Small/Mid Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of companies with small to medium market capitalizations. The Fund invests in small to medium market capitalization companies with attractive fundamental characteristics, including conservative balance sheets, strong returns on invested capital, stable or improving profit margins, ample cash flow, and long-term sales growth potential. The Fund seeks to achieve its investment objective primarily through stock selection, with less emphasis on sector weightings. Under current market conditions, the Advisor defines small and medium-sized companies by reference to those companies within the market capitalization range of the Russell 2500TM Index. As of September 30, 2012, that capitalization range was $42.6 million to $10.1 billion and it is expected to change frequently. Investments in companies that grow above these maximum capitalization criteria may continue to be held if the Advisor believes they remain attractive. The Small/Mid Fund may seek to enhance returns through the use of other investment strategies such as the use of options (for hedging purposes), foreign securities, and other investment companies including ETFs. The Fund may invest up to 20% of its net assets in put and call options. The Fund may invest up to 25% of its net assets in foreign securities, including in ADRs and emerging markets. The Fund also may invest up to 20% of its net assets in other investment companies. The Advisor may sell a position if the fundamentals have deteriorated, a security becomes fully valued, or for purposes of portfolio construction and risk management. The Advisor may also sell a position if a better alternative becomes available. At the discretion of the Advisor, the Small/Mid Fund may invest its assets in cash, cash equivalents, and high-quality, short-term debt securities and money market instruments for temporary defensive purposes in response to adverse market, economic or political conditions.

DAVIDSON INTERMEDIATE FIXED INCOME FUND

Investment Objective

The Davidson Intermediate Fixed Income Fund (the "Intermediate Fund") seeks
income and the preservation of principal.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Intermediate Fund. You may qualify for sales charge discounts if
you and your family invest, or agree to invest in the future, at least $100,000
in the Intermediate Fund. More information about these and other discounts is
available from your financial professional and in the "Class A Shares" section
on page 15 of the Intermediate Fund's statutory Prospectus and the
"Breakpoints/Volume Discounts and Sales Charge Waivers" section on page 47 of
the Intermediate Fund's Statement of Additional Information ("SAI").

Example.

This Example is intended to help you compare the cost of investing in
the Intermediate Fund with the cost of investing in other mutual funds.
The Example assumes that you invest $10,000 in the Intermediate Fund
for the time periods indicated and then either redeem or do not 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 Intermediate
Fund's operating expenses remain the same (taking into account the Expense
Caps only in the first year).

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

Expense Example Davidson Intermediate Fixed Income Fund (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years
Class A	368	633
Class I	70	290

Portfolio Turnover.

The Intermediate 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 the Annual Fund Operating Expenses or in the Example, affect
the Intermediate Fund's performance.

Principal Investment Strategies of the Intermediate Fund

The Intermediate Fund normally invests at least 80% of its net assets (plus any
borrowings for investment purposes) in fixed income securities. The fixed income
securities in which the Fund will generally invest include those of governments,
agencies, inflation-protected securities, asset-backed securities, municipal
bonds and companies across a wide range of industries and market capitalizations
and are generally rated within the BBB-category or better by Standard & Poor's
Rating Group ("Standard & Poor's") or the Baa3 category or better by Moody's
Investors Services ("Moody's"). The Fund normally invests within the intermediate
term structure of the yield curve and will seek to achieve its investment
objective through duration tilts, sector allocations, credit exposures, and
security selection. The maturities of the securities in which the Fund expects
to invest will generally range from 1 to 10 years. The average-dollar weighted
maturity of the securities in which the Fund expects to invest will generally
range from 3 to 10 years. Duration tilts may be interpreted as differences in
the duration of the Fund relative to duration of the benchmark. Duration is a
measure of the sensitivity of the Fund's NAV to interest rate movements. For
fixed-coupon bonds, duration can be intuitively defined as the average maturity
of all bond payments, where each payment is weighted by its value. Duration tilts
will be limited from 75% to 125% of the Barclays Capital Intermediate
Government/Credit Index. The Advisor determines that a particular security should
be purchased by evaluating macroeconomic factors including interest rate trends,
monetary policy, inflation outlook, treasury supply and demand, interest rate
volatility, the strategy duration target, and yield curve position.

The Intermediate Fund may seek to enhance returns through the use of other
investment strategies such as the use of options (for hedging purposes),
investment in foreign securities, and in other investment companies including
exchange-traded funds ("ETFs"). The Fund may invest up to 20% of its net assets
in put and call options. The Fund may invest up to 25% of its net assets in
foreign securities, including in emerging markets. Through its investment in
foreign securities, the Fund may invest up to 20% of its net assets in American
Depositary Receipts ("ADRs"). The Fund also may invest up to 20% of its net
assets in other investment companies and may invest in the securities of small
and medium-sized companies.

The Advisor may sell a position if the fundamentals have deteriorated, a
security becomes fully valued, or for purposes of portfolio construction and
risk management. The Advisor may also sell a position if a better alternative
becomes available.

At the discretion of the Advisor, the Intermediate Fund may invest its assets in
cash, cash equivalents, and high-quality, short-term debt securities and money
market instruments for temporary defensive purposes in response to adverse
market, economic or political conditions.

Principal Risks of Investing in the Intermediate Fund

Losing all or a portion of your investment is a risk of investing in the
Fund. The following principal risks could affect the value of your investment:

·  Asset-Backed Securities Risk. Asset-backed securities may decline in value    
   when defaults on the underlying assets occur and may exhibit additional       
   volatility in periods of changing interest rates. When interest rates decline,
   the prepayment of assets underlying such securities may require the           
   Intermediate Fund to reinvest that money at lower prevailing interest rates,  
   resulting in reduced returns.

·  Credit Risk. The risk that the Intermediate Fund could lose money if the      
   issuer or guarantor of a fixed income security, or the counterparty to a      
   derivative contract, is unable or unwilling to meet its financial obligations.

·  ETF and Mutual Fund Risk. ETFs are typically open-end investment companies    
   that are bought and sold on a national securities exchange. Investment        
   companies (mutual funds) and ETFs have management fees that are part of their
   costs, and the Intermediate Fund will indirectly bear its proportionate share
   of these costs.

·  Foreign and Emerging Market Securities Risk. The Intermediate Fund may invest
   in foreign securities which are subject to special risks. Foreign securities  
   can be more volatile than domestic (U.S.) securities. Securities markets of   
   other countries are generally smaller than U.S. securities markets. Many      
   foreign securities may be less liquid and more volatile than U.S. securities,
   which could affect the Intermediate Fund's investments. The risks are enhanced
   in emerging markets.

·  Foreign Governments Investment Risk. The issuer of the foreign debt or the    
   governmental authorities that control the repayment of such debt may be unable
   or unwilling to repay principal or interest when due, and the Intermediate    
   Fund may have limited recourse in the event of a default. The market prices of
   debt obligations of foreign governments and their agencies, and the           
   Intermediate Fund's net asset value ("NAV"), may be more volatile than prices
   of U.S. debt obligations.

·  Government-Sponsored Entities Risk. Securities issued by government-sponsored
   entities may not be backed by the full faith and credit of the United States.

·  Inflation Protected Securities Risk. Inflation protected securities include   
   the risk that the rate of inflation will be lower than expected or that the   
   relevant index intended to measure the rate of inflation will not accurately  
   measure the rate of inflation and the securities will not work as intended.

·  Interest Rate Risk. The risk that fixed income securities will decline in     
   value because of an increase in interest rates; a fund with a longer average  
   portfolio duration will be more sensitive to changes in interest rates than a
   fund with a shorter average portfolio duration.

·  Issuer Risk. The value of securities held by the Intermediate Fund may        
   experience sudden, unpredictable drops in value or long periods of decline in
   value due to reasons directly related to the issuer, including management     
   performance, financial leverage, and reduced demand for the issuer's goods and
   services.

·  Management Risk. Management risk means that your investment in the            
   Intermediate Fund varies with the success and failure of the Advisor's        
   investment strategies and the Advisor's research, analysis and determination  
   of portfolio securities.

·  New Fund Risk. The Intermediate 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.

·  Options Risk. Options on securities may be subject to greater fluctuations in
   value than an investment in the underlying securities. Purchasing and writing
   put and call options are highly specialized activities and entail greater than
   ordinary investment risks.

·  Small and Medium Companies Risk. Investing in securities of small and medium  
   capitalization companies may involve greater volatility than investing in     
   larger and more established companies because small and medium capitalization
   companies can be subject to more abrupt or erratic share price changes than   
   larger, more established companies.

The Intermediate Fund may be appropriate for investors who:

·  Have a long-term investment horizon; and

·  Want to add an investment with potential for income and to diversify their    
   investment portfolio.

on page 13 of the Equity Income Fund's statutory Prospectus and the
"Breakpoints/Volume Discounts and Sales Charge Waivers" section on page 47 of
the Fund's Statement of Additional Information ("SAI").

Example.

This Example is intended to help you compare the cost of investing in
the Equity Income Fund with the cost of investing in other mutual funds. The
Example assumes that you invest $10,000 in the Equity Income Fund for the time
periods indicated and then either redeem or do not 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 Equity Income Fund's operating expenses remain the
same (taking into account the Expense Caps only in the first year). Although
your actual costs may be higher or lower, based on these assumptions your costs
would be:

If you redeem your shares at the end of the period:

Expense Example Davidson Equity Income Fund (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years
Class A	607	895
Class C	288	646

If you do not redeem your shares at the end of the period:

Expense Example, No Redemption Davidson Equity Income Fund (USD $)	Expense Example, No Redemption, 1 Year	Expense Example, No Redemption, 3 Years
Class A	607	895
Class C	188	646

Portfolio Turnover.

The Equity Income 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 the Annual Fund Operating Expenses or in the Example, affect the Equity Income
Fund's performance.

Principal Investment Strategies of the Equity Income Fund

The Equity Income Fund normally invests at least 80% of its net assets (plus any
borrowings for investment purposes) in equity securities (including convertibles,
preferred stocks, partnerships and limited partnerships). The Fund invests across
a wide range of market capitalizations, while the overall portfolio maintains a
large capitalization emphasis. The equity securities in which the Fund will
generally invest include those which the Advisor believes have attractive
fundamental characteristics, including stable or improving returns on equity, a
solid balance sheet, and ample cash flow. The Fund seeks to achieve its investment
objective through investment in strategically advantaged companies that generate
free cash flow that can be used to reinvest in the company, pay down debt or
distribute to shareholders in the form of dividends and/or share repurchases.

The Equity Income Fund may seek to enhance returns through the use of other
investment strategies such as the use of options (for hedging purposes), foreign
securities, and other investment companies including exchange-traded funds
("ETFs"). The Fund may invest up to 20% of its net assets in put and call
options. The Fund may invest up to 25% of its net assets in foreign securities,
including in American Depositary Receipts ("ADRs") and emerging markets. The
Fund may invest up to 20% of its net assets in other investment companies.

The Advisor may sell a position if the fundamentals have deteriorated, a
security becomes fully valued, or for purposes of portfolio construction and
risk management. The Advisor may also sell a position if a better alternative
becomes available.

At the discretion of the Advisor, the Equity Income Fund may invest its assets
in cash, cash equivalents, and high-quality, short-term debt securities and
money market instruments for temporary defensive purposes in response to adverse
market, economic or political conditions.

Principal Risks of Investing in the Equity Income Fund

Losing all or a portion of your investment is a risk of investing in the Equity
Income Fund. The following principal risks could affect the value of your
investment:

·  Equity Risk. Stock prices may fluctuate widely over short or even extended    
   periods in response to company, market, or economic news. Stock markets also  
   tend to move in cycles, with periods of rising stock prices and periods of    
   falling stock prices.

·  ETF and Mutual Fund Risk. ETFs are typically open-end investment companies    
   that are bought and sold on a national securities exchange. Investment        
   companies (mutual funds) and ETFs have management fees that are part of their
   costs, and the Equity Income Fund will indirectly bear its proportionate share
   of these costs.

·  Foreign and Emerging Market Securities Risk. The Equity Income Fund may invest
   in foreign securities which are subject to special risks. Foreign securities  
   can be more volatile than domestic (U.S.) securities. Securities markets of   
   other countries are generally smaller than U.S. securities markets. Many      
   foreign securities may be less liquid and more volatile than U.S. securities,
   which could affect the Fund's investments. The risks are enhanced in emerging
   markets.

·  Management Risk. Management risk means that your investment in the Equity     
   Income Fund varies with the success and failure of the Advisor's investment   
   strategies and the Advisor's research, analysis and determination of portfolio
   securities.

·  Market and Issuer Risk. The risks that could affect the value of the Equity   
   Income Fund's shares and the total return on your investment include the      
   possibility that the securities held by the Fund will fluctuate as a result of
   the movement of the overall stock market or of the value of the individual    
   securities held by the Fund. The value of securities held by the Fund may also
   experience sudden, unpredictable drops in value or long periods of decline in
   value due to reasons directly related to the issuer, including management     
   performance, financial leverage, and reduced demand for the issuer's goods and
   services.

·  New Fund Risk. The Equity Income 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.

·  Options Risk. Options on securities may be subject to greater fluctuations in
   value than an investment in the underlying securities. Purchasing and writing
   put and call options are highly specialized activities and entail greater than
   ordinary investment risks.

·  Small and Medium Companies Risk. Investing in securities of small and medium  
   capitalization companies may involve greater volatility than investing in     
   larger and more established companies because small and medium capitalization
   companies can be subject to more abrupt or erratic share price changes than   
   larger, more established companies.                                           

The Equity Income Fund may be appropriate for investors who:

·  Have a long-term investment horizon;

·  Want to add an investment with potential for both income and capital          
   appreciation to diversify their investment portfolio;                         

·  Can accept the greater risks of investing in a portfolio with common stock    
   holdings; and                                                                 

.  Are not primarily concerned with principal stability.

This Example is intended to help you compare the cost of investing in the Small/Mid
Fund with the cost of investing in other mutual funds. The Example assumes that you
invest $10,000 in the Small/Mid Fund for the time periods indicated and then either
redeem or do not 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 Small/Mid
Fund's operating expenses remain the same (taking into account the Expense Caps
only in the first year). Although your actual costs may be higher or lower, based
on these assumptions your costs would be:

If you redeem your shares at the end of the period:

Expense Example Davidson Small/Mid Equity Fund (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years
Class A	635	963
Class C	318	716

Expense Example, No Redemption Davidson Small/Mid Equity Fund (USD $)	Expense Example, No Redemption, 1 Year	Expense Example, No Redemption, 3 Years
Class A	635	963

Portfolio Turnover.

The Small/Mid 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 Small/Mid Fund shares are held in a taxable account. These costs,
which are not reflected in the Annual Fund Operating Expenses or in the
Example, affect the Small/Mid Fund's performance.

Principal Investment Strategies of the Small/Mid Fund

Under normal market conditions, the Small/Mid Fund invests at least 80% of its
net assets (plus any borrowings for investment purposes) in equity securities of
companies with small to medium market capitalizations. The Fund invests in small
to medium market capitalization companies with attractive fundamental
characteristics, including conservative balance sheets, strong returns on
invested capital, stable or improving profit margins, ample cash flow, and
long-term sales growth potential. The Fund seeks to achieve its investment
objective primarily through stock selection, with less emphasis on sector
weightings. Under current market conditions, the Advisor defines small and
medium-sized companies by reference to those companies within the market
capitalization range of the Russell 2500TM Index. As of September 30, 2012, that
capitalization range was $42.6 million to $10.1 billion and it is expected to
change frequently. Investments in companies that grow above these maximum
capitalization criteria may continue to be held if the Advisor believes they
remain attractive.

The Small/Mid Fund may seek to enhance returns through the use of other investment
strategies such as the use of options (for hedging purposes), foreign securities,
and other investment companies including ETFs. The Fund may invest up to 20% of its
net assets in put and call options. The Fund may invest up to 25% of its net assets
in foreign securities, including in ADRs and emerging markets. The Fund also may
invest up to 20% of its net assets in other investment companies.

The Advisor may sell a position if the fundamentals have deteriorated, a
security becomes fully valued, or for purposes of portfolio construction and
risk management. The Advisor may also sell a position if a better alternative
becomes available.

At the discretion of the Advisor, the Small/Mid Fund may invest its assets in
cash, cash equivalents, and high-quality, short-term debt securities and money
market instruments for temporary defensive purposes in response to adverse
market, economic or political conditions.

Principal Risks of Investing in the Small/Mid Fund

Losing all or a portion of your investment is a risk of investing in the
Small/Mid Fund. The following principal risks could affect the value of your
investment:

·   Equity Risk. Stock prices may fluctuate widely over short or even extended   
    periods in response to company, market, or economic news. Stock markets also
    tend to move in cycles, with periods of rising stock prices and periods of   
    falling stock prices.

·   ETF and Mutual Fund Risk. ETFs are typically open-end investment companies   
    that are bought and sold on a national securities exchange. Investment       
    companies (mutual funds) and ETFs have management fees that are part of their
    costs, and the Small/Mid Fund will indirectly bear its proportionate share of
    these costs.

·   Foreign and Emerging Market Securities Risk. The Small/Mid Fund may invest in
    foreign securities which are subject to special risks. Foreign securities can
    be more volatile than domestic (U.S.) securities. Securities markets of other
    countries are generally smaller than U.S. securities markets. Many foreign   
    securities may be less liquid and more volatile than U.S. securities, which  
    could affect the Fund's investments. These risks are enhanced in emerging    
    markets.

·   Management Risk. Management risk means that your investment in the Small/Mid
    Fund varies with the success and failure of the Advisor's investment         
    strategies and the Advisor's research, analysis and determination of         
    portfolio securities.

·   Market and Issuer Risk. The risks that could affect the value of the         
    Small/Mid Fund's shares and the total return on your investment include the  
    possibility that the securities held by the Fund will fluctuate as a result  
    of the movement of the overall stock market or of the value of the individual
    securities held by the Fund. The value of securities held by the Fund may    
    experience sudden, unpredictable drops in value or long periods of decline in
    value due to reasons directly related to the issuer, including management    
    performance, financial leverage, and reduced demand for the issuer's goods   
    and services.

·   New Fund Risk. The Small/Mid 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.

·   Options Risk. Options on securities may be subject to greater fluctuations in
    value than an investment in the underlying securities. Purchasing and writing
    put and call options are highly specialized activities and entail greater    
    than ordinary investment risks.

·   Small and Medium Companies Risk. Investing in securities of small and medium
    capitalization companies may involve greater volatility than investing in    
    larger and more established companies because small and medium capitalization
    companies can be subject to more abrupt or erratic share price changes than  
    larger, more established companies.                                          

The Small/Mid Fund may be appropriate for investors who:

·   Have a long-term investment horizon;

·   Want to add an investment with potential for capital appreciation to

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Intermediate Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Intermediate Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in fixed income securities. The fixed income securities in which the Fund will generally invest include those of governments, agencies, inflation-protected securities, asset-backed securities, municipal bonds and companies across a wide range of industries and market capitalizations and are generally rated within the BBB-category or better by Standard & Poor's Rating Group ("Standard & Poor's") or the Baa3 category or better by Moody's Investors Services ("Moody's"). The Fund normally invests within the intermediate term structure of the yield curve and will seek to achieve its investment objective through duration tilts, sector allocations, credit exposures, and security selection. The maturities of the securities in which the Fund expects to invest will generally range from 1 to 10 years. The average-dollar weighted maturity of the securities in which the Fund expects to invest will generally range from 3 to 10 years. Duration tilts may be interpreted as differences in the duration of the Fund relative to duration of the benchmark. Duration is a measure of the sensitivity of the Fund's NAV to interest rate movements. For fixed-coupon bonds, duration can be intuitively defined as the average maturity of all bond payments, where each payment is weighted by its value. Duration tilts will be limited from 75% to 125% of the Barclays Capital Intermediate Government/Credit Index. The Advisor determines that a particular security should be purchased by evaluating macroeconomic factors including interest rate trends, monetary policy, inflation outlook, treasury supply and demand, interest rate volatility, the strategy duration target, and yield curve position. The Intermediate Fund may seek to enhance returns through the use of other investment strategies such as the use of options (for hedging purposes), investment in foreign securities, and in other investment companies including exchange-traded funds ("ETFs"). The Fund may invest up to 20% of its net assets in put and call options. The Fund may invest up to 25% of its net assets in foreign securities, including in emerging markets. Through its investment in foreign securities, the Fund may invest up to 20% of its net assets in American Depositary Receipts ("ADRs"). The Fund also may invest up to 20% of its net assets in other investment companies and may invest in the securities of small and medium-sized companies. The Advisor may sell a position if the fundamentals have deteriorated, a security becomes fully valued, or for purposes of portfolio construction and risk management. The Advisor may also sell a position if a better alternative becomes available. At the discretion of the Advisor, the Intermediate Fund may invest its assets in cash, cash equivalents, and high-quality, short-term debt securities and money market instruments for temporary defensive purposes in response to adverse market, economic or political conditions.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Intermediate Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Losing all or a portion of your investment is a risk of investing in the Fund. The following principal risks could affect the value of your investment: ·  Asset-Backed Securities Risk. Asset-backed securities may decline in value        when defaults on the underlying assets occur and may exhibit additional           volatility in periods of changing interest rates. When interest rates decline,    the prepayment of assets underlying such securities may require the               Intermediate Fund to reinvest that money at lower prevailing interest rates,      resulting in reduced returns. ·  Credit Risk. The risk that the Intermediate Fund could lose money if the          issuer or guarantor of a fixed income security, or the counterparty to a          derivative contract, is unable or unwilling to meet its financial obligations. ·  ETF and Mutual Fund Risk. ETFs are typically open-end investment companies        that are bought and sold on a national securities exchange. Investment            companies (mutual funds) and ETFs have management fees that are part of their    costs, and the Intermediate Fund will indirectly bear its proportionate share    of these costs. ·  Foreign and Emerging Market Securities Risk. The Intermediate Fund may invest    in foreign securities which are subject to special risks. Foreign securities      can be more volatile than domestic (U.S.) securities. Securities markets of       other countries are generally smaller than U.S. securities markets. Many          foreign securities may be less liquid and more volatile than U.S. securities,    which could affect the Intermediate Fund's investments. The risks are enhanced    in emerging markets. ·  Foreign Governments Investment Risk. The issuer of the foreign debt or the        governmental authorities that control the repayment of such debt may be unable    or unwilling to repay principal or interest when due, and the Intermediate        Fund may have limited recourse in the event of a default. The market prices of    debt obligations of foreign governments and their agencies, and the               Intermediate Fund's net asset value ("NAV"), may be more volatile than prices    of U.S. debt obligations. ·  Government-Sponsored Entities Risk. Securities issued by government-sponsored    entities may not be backed by the full faith and credit of the United States. ·  Inflation Protected Securities Risk. Inflation protected securities include       the risk that the rate of inflation will be lower than expected or that the       relevant index intended to measure the rate of inflation will not accurately      measure the rate of inflation and the securities will not work as intended. ·  Interest Rate Risk. The risk that fixed income securities will decline in         value because of an increase in interest rates; a fund with a longer average      portfolio duration will be more sensitive to changes in interest rates than a    fund with a shorter average portfolio duration. ·  Issuer Risk. The value of securities held by the Intermediate Fund may            experience sudden, unpredictable drops in value or long periods of decline in    value due to reasons directly related to the issuer, including management         performance, financial leverage, and reduced demand for the issuer's goods and    services. ·  Management Risk. Management risk means that your investment in the                Intermediate Fund varies with the success and failure of the Advisor's            investment strategies and the Advisor's research, analysis and determination      of portfolio securities. ·  New Fund Risk. The Intermediate 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. ·  Options Risk. Options on securities may be subject to greater fluctuations in    value than an investment in the underlying securities. Purchasing and writing    put and call options are highly specialized activities and entail greater than    ordinary investment risks. ·  Small and Medium Companies Risk. Investing in securities of small and medium      capitalization companies may involve greater volatility than investing in         larger and more established companies because small and medium capitalization    companies can be subject to more abrupt or erratic share price changes than       larger, more established companies. The Intermediate Fund may be appropriate for investors who: ·  Have a long-term investment horizon; and ·  Want to add an investment with potential for income and to diversify their        investment portfolio.
