Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Short Duration 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 92% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock
This Example is intended to help you compare the cost of investing in the Short Duration 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 (taking into account the Expense Caps only in the first year).

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal market conditions, the Short Duration Fund invests primarily in investment-grade debt securities of domestic entities.  Investment-grade debt securities are those rated in one of the four highest rating categories by a nationally recognized statistical rating organization.  An unrated debt security may be treated as investment grade if determined by the Adviser to be of comparable quality.  The Fund may hold securities that, after being purchased, are downgraded to non-investment grade and would no longer qualify for initial investment.  Under normal circumstances, the Fund expects to maintain a weighted average portfolio duration of up to three (3) years.  The Fund defines duration as effective duration which is the interest rate sensitivity of projected cash flows from Fund securities, adjusted for amortization, prepayments, and expected calls and puts.  This means that a debt security’s price would be expected to decrease by approximately 3% with a 1% increase in interest rates.  The Fund believes that effective duration provides the most accurate estimation of the Fund's interest rate sensitivity.

The Short Duration Fund may sell securities short with respect to 25% of its total assets.  The Adviser will primarily sell securities short for the purposes of managing certain risks (primarily interest rate and/or yield spread risk) associated with its long positions.  As a result, short sales will primarily be used for hedging purposes, not for speculative purposes.

Debt securities may include all fixed-income securities (both fixed and floating-rate securities), U.S. Government securities, municipal securities, special purpose entities (such as asset-backed or mortgage-backed security issuers), zero coupon securities, money market securities, repurchase agreements and private asset-backed loan participations.  Certain asset-backed and mortgage-backed securities are issued with stated maturities of 15 to 40 years; however, their effective durations are generally under 3 years.  U.S. Government securities include U.S. Treasury bills, notes and other obligations that are issued by or guaranteed as to interest and principal by the U.S. Government or by agencies or instrumentalities of the U.S. Government.

The Short-Duration Fund may invest in high-quality, short-term debt securities and money market instruments for temporary defensive purposes.

The Adviser will allocate the Short Duration Fund’s assets across different market sectors and different maturities based on its view of the relative value of each sector or maturity.  The Short Duration Fund may purchase and sell securities for a variety of reasons, such as to adjust the portfolio's average maturity, duration, or credit quality or to shift assets into and out of higher yielding or lower yielding securities or different sectors.
Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
Losing all or a portion of your money on your investment is a risk of investing in the Short Duration Fund.  The following additional risks could affect the value of your investment:

·  
Market Risk.  The prices of the securities in which the Short Duration Fund invests may decline for a number of reasons, including in response to economic developments and perceptions about the creditworthiness of individual issuers.

·  
Management Risk.  The Short Duration Fund is an actively managed portfolio.  The Adviser’s management practices and investment strategies might not work to produce the desired results.

·  
Fixed-Income Securities Risk.  The Short Duration Fund may invest in fixed-income (debt) securities, which are generally subject to the following risks:

o  
Credit Risk.  The issuers of the debt securities held by the Fund may not be able to make interest or principal payments.

o  
Extension Risk.  If interest rates rise, repayments of principal on certain fixed-income securities may occur at a slower-than-expected rate and, as a result, the expected maturity of such securities could lengthen which could cause their value to decline.

o  
Interest Rate Risk.  Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates.   It is likely there will be less governmental action in the near future to maintain low interest rates.  The negative impact on fixed income securities from the resulting rate increases for that and other reasons could be swift and significant.

o  
Prepayment Risk.  Issuers of securities held by the Fund may be able to prepay principal due on these securities, particularly during periods of declining interest rates.  Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, and may offer a greater potential for loss when interest rates rise.

·  
Mortgage-Related and Other Asset-Backed Securities Risk.  The Short Duration Fund may invest in a variety of mortgage-related and other asset-backed securities which are subject to Interest Rate Risk, Credit Risk, Extension Risk and Prepayment Risk.

·  
Commercial Mortgage-Backed Securities Risks.  Commercial Mortgage-Backed Securities (“CMBS”) include securities that reflect an interest in, and are secured by, mortgage loans on commercial real estate property.  Many of the risks of investing in CMBS reflect the risks of investing in the real estate securing the underlying mortgage loans.

·  
Counterparty Risk.  Counterparty risk arises upon entering into borrowing arrangements or derivative transactions and is the risk from the potential inability of counterparties to meet the terms of their contracts.

·  
Repurchase Agreement Risk.  Repurchase agreement risk is the risk the counterparty to the repurchase agreement that sells the securities may default on its obligation to repurchase them.  In this circumstance, the Short Duration Fund may lose money because: it may not be able to sell the securities at the agreed-upon time and price, the securities may lose value before they can be sold, the selling institution may default or declare bankruptcy or the Fund may have difficulty exercising rights to the collateral.

·  
Municipal Securities Risk.  The amount of public information available about municipal securities is generally less than that for corporate securities.  Special factors, such as legislative changes, and economic and business developments, may adversely affect the yield and/or value of the Fund’s investments in municipal securities.  Other factors include the general conditions of the municipal securities market, the size of the particular offering, the maturity of the obligation, and the rating of the issue.  Changes in economic, business or political conditions relating to a particular municipal project, municipality, or state in which the Fund invests may have an impact on the Fund’s share price.

·  
U.S. Government Securities Risk. U.S. Government securities, which may be backed by the U.S. Department of the Treasury or the full faith and credit of the U.S., and may include U.S. Treasury bills, Treasury Inflation-Protected Securities, notes and bonds, are guaranteed only as to the timely payment of interest and principal when held to maturity.  The market prices for such securities are not guaranteed and will fluctuate.  Certain U.S. Government agency securities are backed by the right of the issuer to borrow from the U.S. Department of the Treasury, or are supported only by the credit of the issuing agency or instrumentality, and in some cases there may be some risk of default by the issuer.

·  
Government-Sponsored Entities Risk.  Securities issued or guaranteed by government-sponsored entities, including Government National Mortgage Association (“GNMA”), Federal National Mortgage Association (“FNMA”) and Federal Home Loan Mortgage Corporation (“FHLMC”),  may not be guaranteed or insured by the U.S. Government and may only be supported by the credit of the issuing agency.

·  
Short Sales Risk.  A short sale is the sale by the Short Duration Fund of a security which it does not own in anticipation of purchasing the same security in the future at a lower price to close the short position.  A short sale will be successful if the price of the shorted security decreases.  However, if the underlying security goes up in price during the period in which the short position is outstanding, the Fund will realize a loss.  The risk on a short sale is unlimited because the Fund must buy the shorted security at the higher price to complete the transaction.  Therefore, short sales may be subject to greater risks than investments in long positions.

[1] Semper Capital Management, L.P. (the "Adviser") has contractually agreed to waive a portion or all of its management fees and pay Fund expenses to ensure that Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursement (excluding acquired fund fees and expenses, taxes, interest expense, dividends on securities sold short and extraordinary expenses) do not exceed 0.60% of average daily net assets for Institutional Class shares and 0.85% of average daily net assets for Investor Class shares (the "Expense Caps"). The Expense Caps will remain in effect through at least March 29, 2017 and may be terminated only by the Trust's Board of Trustees (the "Board"). The Adviser may request recoupment of previously waived fees and paid expenses from the Fund for three years from the date they were paid, subject to the Expense Caps.
