Risk [Text Block]	Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. The longer the duration of a fixed-income security, the more susceptible it is to interest rate risk. Recent and potential future changes in monetary policy made by central banks and/or their governments are likely to affect the level of interest rates.

Prospectus [Line Items]
Risk [Text Block]	Prepayment and Extension Risk. When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the price of mortgage-backed securities may not rise to as great an extent as that of other fixed-income securities. Should interest rates move in such a manner that the available market mortgage rate significantly exceeds the borrower’s loan rate, homeowners are less likely to prepay their mortgages. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security, and the price of mortgage-backed securities may decrease more than the price of other fixed-income securities.

Risk [Text Block]	MBS Risk. A rise in interest rates may cause the value of MBS held by the Fund to decline. Certain MBS issued by GSEs are not backed by the full faith and credit of the U.S. government. A non-agency MBS is subject to the risk that the value of such security will decline, because the security is not issued or guaranteed as to principal or interest by the U.S. government or a GSE. These securities may have exposure to borrowers with weakened credit histories, increasing the potential for default (subprime risk). The Fund’s investments in collateralized mortgage obligations (CMOs) may entail greater market, prepayment and liquidity risks than other MBS. The liquidity of non-agency MBS and CMOs may also vary dramatically over time.
