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 the 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 42% of the average value of its portfolio.

Portfolio Turnover, Rate rr_PortfolioTurnoverRate 42.00%
Expenses Not Correlated to Ratio Due to Acquired Fund Fees [Text] rr_ExpensesNotCorrelatedToRatioDueToAcquiredFundFees Acquired Fund Fees and Expenses are the indirect expenses of investing in other investment companies. Accordingly, the expense ratio presented in the Financial Highlights section of the prospectus may not correlate to the Total Annual Operating Expense disclosed above.
Expense Example [Heading] rr_ExpenseExampleHeading Example:
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the 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. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, with Redemption, 1 Year rr_ExpenseExampleYear01 $ 92
Expense Example, with Redemption, 3 Years rr_ExpenseExampleYear03 345
Expense Example, with Redemption, 5 Years rr_ExpenseExampleYear05 618

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund intends to invest primarily all, but must invest at least 80%, of its assets in fixed income securities. The Fund invests primarily in debt securities rated within the four highest credit categories (AAA, AA, A, BBB, or equivalent) by at least one nationally recognized statistical rating organization ("NRSRO"), or if unrated, deemed to be of comparable quality by the Fund's sub-adviser. The Fund may invest up to 20% of its assets in fixed income securities rated below such ratings, but no lower than a B rating by an NRSRO at the time of purchase. The Fund seeks to maintain a dollar-weighted average portfolio maturity of four years or more. Under normal market conditions, the Fund will invest no more than 75% of its assets in asset-backed and/or mortgage-backed securities. The Fund may also invest up to 15% of its assets in derivatives and other hedging instruments and up to 40% of its assets in treasury futures to neutralize the impact of interest rate changes.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

The value of the Fund's shares depends on the value of the securities it owns. An investment in the Fund is not a deposit in any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fluctuate significantly, which means loss of money is a risk of the Fund. In addition, the Fund is subject to the following risks:


General Market Risk: Factors affecting the securities markets include domestic and foreign economic growth and decline, interest rate levels, and political events. There is a risk the sub-adviser will not accurately predict the direction of these and other factors and, as a result, the sub-adviser's investment decisions may not accomplish what they were intended to achieve.


Interest Rate Risk: Changes in interest rates affect the value of the Fund's fixed income securities. When interest rates rise, the value of the Fund's fixed income securities and the Fund's shares will decline.


Credit Risk: The Fund could lose money if the issuer of a fixed income security cannot meet its financial obligations or goes bankrupt. The price of a security held by the Fund can be adversely affected prior to actual default if its credit status deteriorates and the probability of default rises.


Guarantee Risk: Mortgage- and asset-backed securities involve the risk that private guarantors may default. There can be no assurance that the private insurers or guarantors of fixed income securities can meet their obligations under the insurance policies or guarantee arrangements.


Reinvestment Risk: If interest rates decline when a fixed income security held by the Fund matures, the cash flows from that security will likely be reinvested at a lower interest rate.


Mortgage-Related and Other Asset-Backed Securities Risk: The risks associated with mortgage-backed securities include: (1) credit risk associated with the performance of the underlying mortgage properties and of the borrowers owning these properties; (2) adverse changes in economic conditions and circumstances, which are more likely to have an adverse impact on mortgage-backed securities comprised of loans on certain types of commercial properties than on those comprised of loans on residential properties; (3) prepayment and extension risks, which can lead to significant fluctuations in the value of the mortgage-backed security; (4) loss of all or part of the premium, if any, paid; and (5) decline in the market value of the security, whether resulting from changes in interest rates or prepayments on the underlying mortgage collateral. Investments in asset-backed securities are subject to risks similar to those associated with mortgage-related securities, as well as additional risks associated with the nature of the assets and the servicing of those assets as described in the Statement of Additional Information.


Derivatives risk: Investing in derivative instruments, such as, swaps, options, futures contracts, forward currency contracts, indexed securities and asset-backed securities, to be announced (TBAs) securities, interest rate swaps, credit default swaps, and certain exchange-traded funds, involves risks, including liquidity, interest rate, market, counterparty, credit and management risks, mispricing or improper valuation. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. These instruments are subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. The Fund could experience losses if its derivative holdings were poorly correlated with its other investments, or if the Fund were unable to liquidate its position because of an illiquid secondary market.

Risk Lose Money [Text] rr_RiskLoseMoney The value of your investment may fluctuate significantly, which means loss of money is a risk of the Fund.
