Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Interest Rate Risk - The market value of a fixed income security is affected significantly by changes (or the expectation of such changes) in interest rates. A wide variety of market and economic factors can cause interest rates to rise or fall, including central bank monetary policy, rising inflation, disinflation or deflation, and changes in general economic conditions. When interest rates rise, the market value of a fixed income security will generally decline and when interest rates decline, the market values of such securities will generally rise. In general, the longer the maturity or duration of a fixed income security, the greater its sensitivity to changes in interest rates. Changes in interest rates can be difficult to forecast and may have unpredictable effects on the markets and the Fund’s investments, including negatively affecting yield, value or liquidity. Actions taken by the Federal Reserve Board or foreign central banks to stimulate or stabilize economic growth, such as increases or decreases in short-term interest rates, may adversely affect markets and the Fund’s performance.
Mortgage Backed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Mortgage-Backed Securities Risk - Mortgage-backed securities represent interests in pools of commercial or residential mortgages and are subject to the risk that borrowers will prepay the principal on their loans more quickly than expected (prepayment risk) when mortgage rates fall or more slowly than expected (extension risk) when mortgage rates rise, which may affect the yield, average life and price of the securities. Because of prepayment risk and extension risk, mortgage-backed securities react differently to changes in interest rates than other fixed income securities. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-backed securities.
US Government Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] U.S. Government Securities Risk - U.S. government securities may be adversely affected by changes in interest rates (interest rate risk) or a default by or decline in the credit rating of the U.S. government (credit risk).
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Risk - The value of the Fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting (or perceived to affect) specific issuers held by the Fund, particular industries represented in the Fund’s portfolio, or the overall securities markets. A variety of factors can increase the volatility of the Fund’s holdings and markets generally, including political or regulatory developments, recessions, inflation, deflation, rapid interest rate changes, bank failures, war or acts of terrorism, sanctions, tariffs, natural disasters, outbreaks of infectious illnesses or other widespread public health issues, general outlook for corporate earnings, or adverse investor sentiment generally. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors and industries more significantly than others. These adverse developments may cause broad declines in an issuer’s value due to short-term market movements or for significantly longer periods during more prolonged market downturns.
US Government Sponsored Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] U.S. Government-Sponsored Securities Risk - Securities issued by U.S. government-sponsored enterprises (“GSEs”), such as the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association and the Federal Home Loan Banks, may be adversely affected by changes in interest rates (interest rate risk) or a default by or decline in the credit rating of the applicable GSE (credit risk). Securities of GSEs are not issued or guaranteed by the U.S. Treasury and are not backed by the full faith and credit of the U.S. government.
Asset Backed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Asset-Backed Securities Risk - Asset-backed securities represent interests in pools of assets, including consumer loans, auto loans, student loans, or receivables held in trust. The value of asset-backed securities may be affected by certain factors such as interest rate risk; the credit performance of the pool of underlying assets; the creditworthiness of the servicing agent or the originator of the underlying assets; the ability of the servicing agent to service the underlying collateral; and the availability of information concerning the pool of underlying assets and its structure. Asset-backed securities are also subject to the risk that borrowers will prepay the principal on their loans more quickly than expected (prepayment risk) in a declining interest rate environment or more slowly than expected (extension risk) in a rising interest rate environment.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk - The use of derivatives, including but not limited to futures contracts on U.S. Treasury securities, may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. These risks include imperfect correlations with underlying investments or the Fund’s other portfolio holdings, magnified losses resulting from leverage, counterparty risk, high price volatility, liquidity risk, segregation risk, valuation risk and legal restrictions.
To Be Announced Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] To-Be-Announced Securities Risk - TBA securities involve the risk that a security the Fund buys will lose value prior to its delivery. There is also the risk that the security will not be issued or that the other party to the transaction will not meet its obligations. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.
Mortgage Dollar Roll Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Mortgage Dollar Roll Risk - Mortgage dollar roll transactions involve the risk that the market value of the securities sold by the Fund may decline below the repurchase price of those securities. Since the counterparty in the transaction is required to deliver a similar, but not identical, security to the Fund, the security the Fund is required to buy under the mortgage dollar roll may be worth less than an identical security. These transactions involve the risk that the portfolio managers may not correctly predict mortgage prepayments and interest rates, which may diminish the Fund’s performance. In addition, investment in mortgage dollar rolls may increase the Fund’s portfolio turnover rate, which can increase the Fund’s expenses and decrease returns. There is no assurance that the Fund’s use of cash it receives from a mortgage dollar roll will provide a return that exceeds borrowing costs.
Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit Risk - An issuer (or guarantor) of a security may default on its obligations to pay principal or interest. A security’s value may be affected by changes in its credit quality rating or its issuer’s financial conditions.
Call Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Call Risk - An issuer may redeem a fixed income security before maturity (a “call”) at a price below its current market value.
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management Risk - A strategy, investment decision, technique, analysis, or model used by the portfolio managers may fail to produce the intended results, or imperfections, errors or limitations in the tools and data used by the portfolio managers may cause unintended results. Therefore, the Fund could underperform in comparison to other funds with similar objectives and investment strategies and may generate losses even in a favorable market.
Portfolio Turnover Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Portfolio Turnover Risk - High portfolio turnover rates generally result in higher transaction costs (which are borne directly by the Fund and indirectly by the Fund’s shareholders).
