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 108% of the average value of its portfolio.

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. The Adviser considers securities to be of investment grade quality if they are rated BBB (or comparable) or higher by a nationally recognized credit rating organization including Standard & Poor’s Ratings Services (“S&P”) and Moody’s Investors Service, Inc. (“Moody’s”), or if unrated, 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 or for capturing differences in value between two securities, and not for forecasting the market’s direction.  As a result, short sales will primarily be used for hedging purposes, not for speculative purposes.  In many instances, the Fund will utilize forward-settling sales of agency residential mortgage-backed securities (“RMBS”) where the underlying pools of mortgage loans are To Be Announced (“TBA”) securities for these short selling activities.

Debt securities may include all fixed-income securities (both fixed and floating-rate securities), Rule 144A 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 Fund may also invest in high yield instruments that are rated below investment grade (i.e., “high yield” or “junk” ratings).  The Fund may also invest up to 10% of its total assets in other investment companies, including exchange-traded funds (“ETFs”).

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:

·
General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

·
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.  Fixed-income (debt) securities 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.  Fixed income securities may 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.  When securities are prepaid, the Short Duration Fund may have to reinvest in securities with a lower yield.

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

·
Risks Associated with Mortgage-Backed Securities (“MBS”).  These risks include Market Risk, Interest Rate Risk, Credit Risk and Prepayment Risk, as well as the risk that the structure of certain MBS may make their reaction to interest rates and other factors difficult to predict, which may cause their prices to be very volatile.  Limited trading opportunities for certain MBS may make it more difficult to sell or buy a security at a favorable price or time.  In particular, events related to the U.S. housing market  have in the recent past had a severe negative impact on the value of some MBS and resulted in an increased risk associated with investments in these securities.

·
Residential Mortgage-Backed Securities Risks.  RMBS are subject to the risks generally associated with mortgage-backed securities.  RMBS may not be backed by the full faith and credit of the U.S. Government and are subject to risk of default on the underlying mortgages.  RMBS issued by non-government entities may offer higher yields than those issued by government entities, but also may be subject to greater volatility than government issues.  Delinquencies and defaults by borrowers in payments on the underlying mortgages, and the related losses, are affected by general economic conditions, the borrower’s equity in the mortgaged property and the borrower’s financial circumstances.  The risks associated with RMBS are greater for those in the Alt-A first lien mortgage sectors than those in the prime first lien mortgage sectors, but the risks exist for all RMBS.  In the recent past, delinquency and defaults on residential mortgages have increased and may continue to increase.

·
Commercial Mortgage-Backed Securities (“CMBS”) Risks.  CMBS are subject to the risks generally associated with mortgage-backed securities.  CMBS may not be backed by the full faith and credit of the U.S. Government and are subject to risk of default on the underlying mortgages.  CMBS issued by non-government entities may offer higher yields than those issued by government entities, but also may be subject to greater volatility than government issues.  CMBS react differently to changes in interest rates than other bonds and the prices of CMBS may reflect adverse economic and market conditions.  Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of CMBS.

·
Privately Issued Mortgage-Related Securities Risk.  MBS issued or guaranteed by private issuers is also known as “non-agency MBS”.  Privately issued mortgage-backed securities generally offer a higher rate of interest (but greater credit risk) than securities issued by U.S. Government issuers, as there are no direct or indirect governmental guarantees of payment.  The degree of risks will depend significantly on the ability of borrowers to make payments on the underlying mortgages and the seniority of the security held by the Fund with respect to such payments.  The market for privately-issued mortgage-backed securities is smaller and less liquid than the market for mortgage-backed securities issued by U.S. government issuers.

·
Sub-Prime Mortgage Risk.  The risk that an issuer of a sub-prime mortgage security will default on its payments of interest or principal on a security when due.  These risks are more pronounced in the case of sub-prime mortgage instruments than more highly ranked securities.  Because of this increased risk, these securities may also be less liquid and subject to more pronounced declines in value than more highly rated instruments in times of market stress.

·
Risks Associated with Real Estate and Regulatory Actions.  The securities that the Fund owns are dependent on real estate prices.  If real estate experiences a significant price decline, this could adversely affect the prices of the securities the Fund owns.  Any adverse regulatory action could impact the prices of the securities the Fund owns.

·
Rule 144A Securities Risk.  The market for Rule 144A securities typically is less active than the market for publicly-traded securities.  Rule 144A securities carry the risk that the liquidity of these securities may become impaired, making it more difficult for the Fund to sell these securities.

·
High Yield Risk. Fixed income securities that are rated below investment grade (i.e., “junk bonds”) are subject to additional risk factors due to the speculative nature of the securities, such as increased possibility of default liquidation of the security, and changes in value based on public perception of the issuer.

·
Derivatives Risk.  A derivative security is a financial contract whose value is based on (or “derived from”) a traditional security (such as a bond) or a market index, and includes options, futures and swaps.  Derivatives involve the risk of improper valuation, the risk of ambiguous documentation and the risk that changes in the value of the derivative may not correlate perfectly with the underlying security.

·
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.

·
Leverage Risk.  Leverage is the practice of borrowing money to purchase securities.  Leverage can increase the investment returns of the Fund if the securities purchased increase in value in an amount exceeding the cost of the borrowing.  However, if the securities decrease in value, the Fund will suffer a greater loss than would have resulted without the use of leverage.

·
TBA Securities Risk. In a TBA transaction, a seller agrees to deliver a security at a future date, but does not specify the particular security to be delivered.  Instead, the seller agrees to accept any security that meets specified terms.  The principal risks of TBA transactions are increased interest rate risk and increased overall investment exposure.

·
Liquidity Risk.  Liquidity risk exists when particular investments are difficult to purchase or sell. The Short Duration Fund’s investments in illiquid securities may reduce the returns of the Fund because it may be difficult to sell the illiquid securities at an advantageous time or price. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed-income securities or the lack of an active market. Liquid investments may become illiquid or less liquid after purchase by the Short Duration Fund, particularly during periods of market turmoil. Illiquid and relatively less liquid investments may be harder to value, especially in changing markets.

·
Investment Company Risk.  When the Fund invests in an ETF or mutual fund, it will bear additional expenses based on its pro rata share of the ETF’s or mutual fund’s operating expenses, including the potential duplication of management fees.  The risk of owning an ETF or mutual fund generally reflects the risks of owning the underlying securities the ETF or mutual fund holds.  The Fund also will incur brokerage costs when it purchases ETFs.

·
When-Issued Securities Risk.  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.

·
Portfolio Turnover Risk.  A high portfolio turnover rate (100% or more) has the potential to result in the realization and distribution to shareholders of higher capital gains, which may subject you to a higher tax liability.  A high portfolio turnover rate also leads to higher transactions costs.

·
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 (“Ginnie Mae”), Federal National Mortgage Association (“Fannie Mae”) and Federal Home Loan Mortgage Corporation (“Freddie Mac”),  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 AFFE, 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, 2018 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.
