Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

Portfolio Turnover. The Fund pays transaction costs 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 for you if your 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

Example. This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in Investor Shares of the Fund for the time periods indicated, your investment has a 5% return each year, and the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, the Example shows what your costs would be based on these assumptions. The Example is based, through February 28, 2021, on the Net Annual Fund Operating Expenses and, for all other periods, on Total Annual Fund Operating Expenses.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Adviser and the Fund's sub-adviser, Schroder Investment Management North America Ltd. ("SIMNA Ltd." or the "Sub-Adviser"), seek to invest the Fund's assets in a portfolio of securities that offer high total return – from current income, increases in market value, or both. The Fund normally invests at least 80% of its net assets in fixed income obligations. This policy is non-fundamental and may be changed by the Trustees, without a vote of the shareholders of the Fund, upon at least 60 days' prior written notice to shareholders. The Fund may use derivatives and exchange-traded funds ("ETFs") with economic characteristics similar to fixed income obligations for purposes of complying with this policy. The Adviser and the Sub-Adviser currently consider fixed income obligations to include U.S. and foreign government securities, debt securities of domestic and foreign corporations, mortgage-backed and other asset-backed securities (which may include "to be announced" ("TBA") transactions), municipal bonds, obligations of international agencies or supranational entities, zero-coupon securities, convertible securities, inflation-indexed bonds, structured notes, including hybrid or "indexed" securities, event-linked bonds, and loan participations, delayed funding loans and revolving credit facilities, and short-term investments, such as repurchase agreements, bank certificates of deposit, fixed time deposits, and bankers' acceptances. Fixed income securities in which the Fund invests may include securities that pay interest at fixed, floating or variable rates. The Fund may invest in securities of issuers located anywhere in the world, but will normally not invest more than 20% of its total assets in securities that are not denominated in the U.S. dollar. The Adviser and the Sub-Adviser currently expect that a substantial portion of the Fund's assets will be invested in mortgage-backed securities (including collateralized mortgage obligations) and asset-backed securities. The Fund invests principally in securities that, at the time of purchase, are rated "investment grade" (or considered by the Adviser and the Sub-Adviser to be of comparable quality) although the Fund may invest up to 30% of its total assets in securities below "investment grade," which are sometimes referred to as "high yield securities" or "junk bonds." The Fund intends to maintain an average effective portfolio duration that is within 30% of the average effective duration of the Bloomberg Barclays U.S. Aggregate Bond Index. Duration is a measure of a debt security's price sensitivity to a given change in interest rates; effective duration is a measure of the Fund's portfolio duration adjusted for the anticipated effect of interest rate changes on pre-payment rates. Generally, the higher a bond's duration, the greater its price sensitivity to a change in interest rates. In contrast to duration, maturity measures only the time until final payment is due. The Adviser and the Sub-Adviser generally rely on detailed proprietary research, and focus on sectors and securities they believe are undervalued relative to the market. The Adviser and the Sub-Adviser seek to exploit inefficiencies in the valuation of risk and reward and look to capitalize on shifting market risks and dynamics caused by economic and technical factors. The Adviser and the Sub-Adviser consider the liquidity of securities and the portfolio overall as an important factor in portfolio construction. The Adviser and Sub-Adviser also consider certain environmental, social and/or governance (ESG) factors when assessing investment opportunities that otherwise meet their investment critera. The Fund may enter into derivatives transactions such as interest rate futures and options, interest rate swap agreements, forward contracts, and credit default swaps for hedging purposes, or otherwise to increase total return, or to gain long or short exposure to securities or market sectors as a substitute for cash investments (not for leverage) or pending the sale of securities by the Fund and reinvestment of the proceeds. The Fund may, but is not required to, enter into foreign currency exchange transactions, for hedging purposes or to adjust the exposure of the Fund to changes in the values of various foreign currencies. The Fund may hedge some of its foreign currency exposure back into the U.S. dollar, although it does not normally expect to do so. The Fund may invest in ETFs (open-end investment companies whose shares may be bought and sold by investors in transactions on major stock exchanges).

The Fund may engage in active and frequent trading of portfolio securities in seeking to achieve its investment objective.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

It is possible to lose money on an investment in the Fund. The Fund will be affected by the investment decisions, techniques and risk analyses of the Fund's investment team and there is no guarantee that the Fund will achieve its investment objective. The values of investments held by the Fund may fluctuate in response to actual or perceived issuer, political, market, and economic factors influencing the financial markets generally, or relevant industries or sectors within them. Fluctuations may be more pronounced if the Fund invests substantially in one country or group of countries or in companies with smaller market capitalizations. Other principal risks of investing in the Fund include:

●

Active Investment Management Risk: The risk that, if the Adviser's and the Sub-Adviser's investment strategy does not perform as expected, the Fund could underperform its peers or lose money;

●

Market Risk: the risk that the markets will perform poorly or that the returns from the securities in which the Fund invests will underperform returns from the general securities markets or other types of investments. Markets may, in response to governmental actions or intervention, economic or market developments, or other external factors, experience periods of high volatility and reduced liquidity. During those periods, the Fund may experience high levels of shareholder redemptions, and may have to sell securities at times when the Fund would otherwise not do so, potentially at unfavorable prices. Certain securities, particularly fixed income securities, may be difficult to value during such periods;

●

Debt Securities Risk: investing in debt securities may expose the Fund to "Credit Risk," "Interest Rate Risk," "Valuation Risk," and "Inflation/Deflation Risk," among other risks;

●

Interest Rate Risk: fixed income, or debt, securities generally decline in value in response to increases in interest rates; in addition, as interest rates fall, borrowers may prepay their obligations, generally requiring the recipients to reinvest those payments in instruments paying interest at lower rates. Generally, the higher a debt security's duration, the greater its price sensitivity to a change in interest rates;

●

Credit Risk: the ability, or perceived ability, of the issuer of a debt security to make timely payments of interest and principal will affect the security's value, especially for speculative securities below investment grade ("high yield bonds" or "junk bonds");

●

High Yield/Junk Bond Risk: lower-quality debt securities can involve a substantially greater risk of default than higher quality debt securities, and their values can decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general;

●

Rating Agencies Risk: ratings reflect only the views of the originating rating agencies. There is no assurance that a particular rating will continue for any given period of time or that any such rating will not be revised downward or withdrawn entirely if, in the judgment of the agency establishing the rating, circumstances warrant. A downward revision or withdrawal of such ratings, or both, may have an effect on the liquidity or market price of the securities in question;

●

Inflation/Deflation Risk: the value of the Fund's investments may decline as inflation reduces the value of money; conversely, if deflation reduces prices throughout the economy there may be an adverse effect on the creditworthiness of issuers in whose securities the Fund invests;

●

Foreign Securities Risk: investments in non-U.S. issuers may be affected by adverse political, regulatory, economic, market or other developments affecting issuers located in foreign countries, or by foreign withholding taxes;

●

Foreign Currencies Risk: the value of the Fund's assets may be affected favorably or unfavorably by currency exchange rates, currency exchange control regulations, and restrictions or prohibitions on the repatriation of foreign currencies;

●

Emerging Markets Securities Risk: compared to foreign developed markets, investing in emerging markets may involve heightened volatility, greater political, regulatory, legal and economic uncertainties, less liquidity, dependence on particular commodities or international aid, high levels of inflation, and certain special risks associated with smaller capitalization companies;

●

Mortgage-Backed and Asset-Backed Securities Risk: investing in mortgage- and asset-backed securities involves interest rate, credit, valuation, and liquidity risks and the risk that payments on the underlying assets are delayed, prepaid, subordinated or defaulted on;

●

Municipal Securities Risk: economic, political or regulatory changes may impact the ability of municipal issuers to repay principal and to make interest payments on municipal securities. Changes in the financial condition or credit rating of municipal issuers also may adversely affect the value of the Fund's municipal securities. Interest and principal on some municipal securities are payable only out of limited income or revenue streams;

●

U.S. Government Securities Risk: securities issued or guaranteed by certain agencies and instrumentalities of the U.S. Government may not be supported by the full faith and credit of the United States; investing in such securities may involve interest rate and mortgage and asset-backed securities risks;

●

Liquidity Risk: at times, the Fund may be invested in illiquid securities that may be highly volatile, difficult to value, and difficult to sell or close out at favorable prices or times. Investments in foreign securities tend to have greater exposure to liquidity risk;

●

Portfolio Turnover Risk: if the Fund frequently trades its securities, this will increase transaction costs, may result in taxable capital gains, and may lower investment performance;

●

Counterparty Risk: a counterparty (the other party to a transaction or an agreement or the party with whom the Fund executes transactions) to a transaction with the Fund may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations;

●

Valuation Risk: certain securities may be difficult to value, and there can be no assurance that the valuation placed on a security held by the Fund will reflect that actual price at which the security might be sold in a market transaction;

●

Large Shareholder Risk: certain account holders may from time to time own or control a significant percentage of the Fund's shares. The Fund is subject to the risk that a redemption by large shareholders of all or a portion of their Fund shares or a purchase of Fund shares in large amounts and/or on a frequent basis, including as a result of asset allocation decisions, will adversely affect the Fund's performance if it is forced to sell portfolio securities or invest cash when the Adviser and the Sub-Adviser would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund's portfolio, increase the Fund's transaction costs and/or lead to the liquidation of the Fund;

●

Derivatives Risk: investing in derivative instruments, including futures, options, swap agreements and forward contracts, may be considered speculative and involves leverage, liquidity, credit, interest rate and valuation risks and the risk of losing more than the principal amount invested. Derivatives also involve the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate, or index;

●

LIBOR Replacement Risk: The elimination of the London Inter-Bank Offered Rate ("LIBOR") may adversely affect the interest rates on, and value of, certain Fund investments for which the value is tied to LIBOR. The U.K. Financial Conduct Authority has announced that it intends to stop compelling or inducing banks to submit LIBOR rates after 2021. However, it remains unclear if LIBOR will continue to exist in its current, or a modified, form. Alternatives to LIBOR are established or in development in most major currencies, including the Secured Overnight Financing Rate ("SOFR"), which is intended to replace U.S. dollar LIBOR. Markets are slowly developing in response to these new rates. Questions around liquidity impacted by these rates, and how to appropriately adjust these rates at the time of transition, remain a concern for the Fund. Accordingly, it is difficult to predict the full impact of the transition away from LIBOR on the Fund until new reference rates and fallbacks for both legacy and new products, instruments and contracts are commercially accepted;

●

Leverage Risk: the use of leverage can amplify the effects of market volatility on the Fund's share price and may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet any required asset segregation requirements;

●

"To Be Announced" Transactions Risk: TBA transactions may create investment leverage; the ability of the Fund to benefit from its investment in a TBA transaction will depend on the ability and willingness of its counterparty to perform its obligations to the Fund;

●

Convertible Securities Risk: debt securities that are convertible into preferred or common stocks are subject to the risks of both debt and equity securities;

●

Loan Risk: investments in loans are generally subject to the same risks as investments in other types of debt securities, including, in many cases, investments in high yield/junk bonds. They may be difficult to value and may be illiquid; and

●

Investments in Pooled Vehicles Risk: investing in another investment company subjects the Fund to that company's risks, and, in general, to a pro rata portion of that company's fees and expenses. Investing in another investment company also involves liquidity risk and valuation risk.

Please see "Principal Risks of Investing in the Funds" in the Fund's full Prospectus for a more detailed description of the Fund's risks. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

After-tax returns are not relevant to investors who hold their shares in the Fund through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts. In some cases, the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

Portfolio Turnover. 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 for you if your 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 134% of the average value of its portfolio.

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

Example. This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in R6 Shares of the Fund for the time periods indicated, your investment has a 5% return each year, and the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, the Example shows what your costs would be based on these assumptions. The Example is based, through February 28, 2021, on Net Annual Fund Operating Expenses and, for all other periods, on Total Annual Fund Operating Expenses.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing primarily in a portfolio of U.S. dollar-denominated, investment grade fixed income securities. The Fund's total return includes income earned on the Fund's investments, plus capital appreciation, if any.

Fixed income securities in which the Fund may invest include obligations of governments, government agencies or instrumentalities, supra-national issuers, or corporate issuers. They may pay fixed, variable, or floating interest rates and may include asset-backed securities, mortgage-backed securities (which may include "to be announced" ("TBA") transactions), zero-coupon securities, convertible securities, inflation-indexed bonds, structured notes, bank loans, loan participations, loan assignments, municipal securities, and other securities bearing fixed or variable interest rates of any maturity. "Investment-grade" securities are securities that, at the time of purchase, are rated by at least one major rating agency in one of its top four rating categories, or, if unrated, are determined by the Adviser and the Fund's sub-adviser, Schroder Investment Management North America Ltd. ("SIMNA Ltd." or the "Sub-Adviser"), to be of similar quality. In the case of a split rated security (that is, two or more rating agencies give a security different ratings), the highest rating shall apply. The Fund may invest without limit in U.S. dollar denominated foreign securities. The Fund may invest in exchange-traded funds ("ETFs") (open-end investment companies whose shares may be bought and sold by investors in transactions on major stock exchanges). The Fund may also invest a portion of its assets in cash and cash equivalents. The Fund normally invests at least 80% of its net assets, plus the amount of any borrowing for investment purposes, in fixed income securities. This investment policy may be changed by the Fund upon 60 days' prior notice to shareholders. The Fund may use derivatives and ETFs with economic characteristics similar to fixed income securities for purposes of complying with this policy. At times, the Fund's investments in municipal securities may be substantial depending on the Adviser's and the Sub-Adviser's outlook on the market.

While the Fund may invest in fixed income securities of any maturity or duration, under normal market conditions, the Adviser and the Sub-Adviser seek to maintain an average effective portfolio duration that is within 20% of the average effective duration of the Fund's benchmark, the Bloomberg Barclays U.S. Aggregate Bond Index, on an adjusted basis. The Adviser and Sub-Adviser generally adjust the duration of tax-exempt municipal bonds by a factor (currently 0.7) to reflect the view that their prices are typically less sensitive to changes in interest rates than taxable securities. Duration is a measure of a debt security's price sensitivity to a given change in interest rates; effective duration is a measure of the Fund's portfolio duration adjusted for the anticipated effect of interest rate changes on pre-payment rates. Generally, the higher a debt security's duration, the greater its price sensitivity to a change in interest rates. In contrast to duration, maturity measures only the time until final payment is due.

The Adviser's and the Sub-Adviser's decision to purchase or sell a security or make investments in a particular sector is based on relative value considerations. In analyzing the relative attractiveness of a particular security or sector, the Adviser and the Sub-Adviser assess an issue's historical relationships to other bonds, technical factors including supply and demand and fundamental risk and reward relationships, as well as certain environmental, social and/or governance (ESG) factors. When making decisions to purchase or sell a security, the Adviser and Sub-Adviser also consider a number of factors including sector exposures, interest rate duration, yield and the relationship between yields and maturity dates.

The Adviser and the Sub-Adviser may engage actively in transactions involving derivatives in managing the Fund. Derivative transactions may include exchange-traded or over-the-counter derivatives, such as swap contracts including interest rate swaps, total return swaps, and credit default swaps, and futures contracts and options on futures (typically for the purposes of interest rate or other risk management or as a substitute for direct investment), and foreign currency exchange transactions, including currency futures, forwards, and option transactions (typically to hedge against changes in the values of currencies in which investments are denominated). The notional value of the Fund's investments in derivatives that provide exposure comparable, in the judgment of the adviser, to investments in fixed income securities may be counted toward satisfaction of the 80% policy described above.

The Fund may engage in active and frequent trading of portfolio securities in seeking to achieve its investment objective.

After-tax returns are estimated using 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 investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their shares in the Fund through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts. In some cases, the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.
