Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

 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. During the most recent fiscal year, the Fund’s portfolio turnover rate was 19% of the average value of the portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund:
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund invests primarily in exchange traded funds (“ETFs”), other open-end mutual funds, and closed-end funds.  This group of investments is referred to as "Underlying Funds." The Fund’s investment adviser, CLS Investments, LLC (“CLS”), seeks to achieve the Fund’s investment objective by using the following investment strategies:


·


Investing in (i) Underlying Funds that seek capital growth or appreciation by investing in common stock or securities convertible into or exchangeable for common stock (such as convertible preferred stock, convertible debentures or warrants), including the stock of foreign issuers, or (ii) individual securities that may provide capital appreciation. The Underlying Funds used by the Fund in its allocations consist primarily of ETFs. The Underlying Funds are selected based on the security selection methodology used by the Underlying Fund's adviser, as well as CLS's assessment of asset class trends, asset class fundamentals, diversification impact, fundamental research and the cost and liquidity of the Underlying Fund.  These investments may include smaller and medium capitalization companies.


·


Although the Fund does not seek current income, it may invest up to 20% of its total assets in long, medium, or short-term bonds and other fixed income securities of any credit quality(including "junk bonds"), or Underlying Funds that invest in these securities, whenever CLS believes these investments offer a potential for capital appreciation.  Fixed income securities principally include U.S. and foreign government bonds, U.S. government agency bonds, corporate bonds, asset-backed securities and mortgage-backed securities.   


The Fund’s portfolio is invested to maintain risk levels similar to those of the S&P 500 Index. The S&P 500 Index is an unmanaged index made up of 500 blue chip stocks.  CLS seeks to control risk within a given range by estimating the cumulative risk of the Fund's investments and keeping it near that of the S&P 500 Index.  The risk of an asset is based on its volatility, long-term performance, valuations, and other financial and economic data.  The volatility of the asset has the largest impact on the risk measurement.


CLS actively manages the Fund's investments by increasing or decreasing the Fund’s investment in particular asset classes, sectors, regions and countries, or in a particular security, based on its assessment of the opportunities for return relative to the risk using fundamental and technical analysis.  Because of the varying levels of risk amongst equity and bond asset classes, the percent allocated to equities and bonds will vary depending on which asset classes are selected for the portfolio.  When selecting Underlying Funds for investment, CLS considers the Underlying Fund’s investment goals and strategies, the investment adviser and portfolio manager, and past performance (absolute, relative and risk-adjusted).  When CLS selects individual equity securities, it considers both growth prospects and anticipated dividend income.  CLS selects bond funds and bonds based on an analysis of credit qualities, maturities, and coupon or dividend rates, while seeking to take advantage of yield differentials between securities.  CLS may sell an investment if it determines that the asset class, sector, region or country is no longer desirable or if CLS believes that another Underlying Fund or security within the category offers a better opportunity to achieve the Fund’s objective.    

Risk [Heading] rr_RiskHeading Principal Risks of the Fund:
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Many factors affect the Fund’s performance. The Fund's share price changes daily based on changes in market conditions in response to economic, political and financial developments. The direction and extent of those price changes will be affected by the financial condition, industry and economic sector, and geographic location of the securities in which the Fund and the Underlying Funds invest.  The Fund is not federally insured or guaranteed by any government agency.  YOU MAY LOSE MONEY BY INVESTING IN THE FUND.


Debt Securities Risk:  When the Fund invests in bonds or in Underlying Funds that own bonds, the value of your investment in the Fund will fluctuate with changes in interest rates.  Longer-term bonds are generally more sensitive to interest rate changes than short-term bonds and therefore may carry more risk.  Issuers of fixed-income securities may default on interest and principal payments.  Generally, securities with lower debt ratings (“junk bonds”) have greater credit risk.


Foreign Securities Risk:  Foreign securities may be riskier than U.S. investments because of factors such as unstable international political and economic conditions, currency fluctuations, foreign controls on investment and currency exchange, withholding taxes, a lack of adequate company information, less liquid and more volatile markets, and a lack of governmental regulation.  Foreign companies generally are not subject to accounting, auditing, and financial reporting standards comparable to those applicable to U.S. companies.  Transaction costs and costs associated with custody services are generally higher for foreign securities than they are for U.S. securities.  


Management Risk:  The ability of the Fund to meet its investment objective is directly related to the allocation of the Fund’s assets.  CLS may allocate the Fund's investments so as to under-emphasize or over-emphasize investments under the wrong market conditions, in which case the Fund’s value may be adversely affected.


Market Risk:  Investments in securities in general are subject to market risks that may cause their prices to fluctuate over time. The Fund’s investments may decline in value due to factors affecting securities markets generally, or particular countries, segments, economic sectors, industries or companies within those markets. The value of a security may decline due to general economic and market conditions that are not specifically related to a particular issuer.


Smaller and Medium Issuer Risk:  Investments in Underlying Funds that own small and medium capitalization companies and direct investments in individual small and medium capitalization companies may be more vulnerable than larger, more established organizations to adverse business or economic developments.


Underlying Funds Risk:  You will indirectly pay fees and expenses charged by the Underlying Funds in addition to the Fund’s direct fees and expenses.  As a result, the cost of investing in the Fund will be higher than the cost of investing directly in Underlying Fund shares and may be higher than other mutual funds that invest directly in stocks and bonds. Each Underlying Fund is subject to specific risks, depending on the nature of the Underlying Fund. These risks could include sector risk (increased risk from a focus on one or more sector of the market), as well as risks associated with fixed income securities, real estate investments, and commodities.

[1] This number represents the combined total fees and operating expenses of the Underlying Funds owned by the Fund and is not a direct expense incurred by the Fund or deducted from Fund assets. Since this number does not represent a direct operating expense of the Fund, the operating expenses set forth in the Fund's financial highlights do not include this figure.
[2] The fees shown above take into account CLS's advisory fee waiver agreement to limit total operating expenses at least through December 31, 2014 , so that Class N Share and Class C Share direct expenses (not including expenses relating to dividends on short sales, interest expense, indirect fees and expenses of Underlying Funds and extraordinary or non-recurring expenses) do not exceed 1.15% and 2.15% of average daily net assets; respectively. Only the Fund's Board of Trustees may elect to terminate the advisory fee waiver agreement.
[3] The Fund's Class C Shares commenced operations on July 13, 2000.
[4] Class N Shares have lower expenses than Class C Shares of the Amerigo Fund, and unlike Class C Shares, are not subject to any contingent deferred sales charge.
[5] After-tax returns are shown for Class N Shares only and will differ from Class C Shares because Class C Shares have a higher expense ratio. After-tax returns are based on the highest historical individual federal marginal income tax rates, and do not reflect the impact of state and local taxes; actual after-tax returns depend on an individual investor's tax situation and may differ from those shown. If you own shares of the Fund in a tax-deferred account, such as an individual retirement account or a 401(k) plan, this information is not applicable to your investment. A higher after-tax return results when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder.
