FNMA and FHLMC are chartered or sponsored by Acts of Congress; however, their securities are neither issued nor guaranteed by the U.S. Treasury. The Funds investments in mortgage-related securities include investments in stripped mortgage-backed securities such as interest-only (IO) and principal-only (PO) securities. The Fund may invest in debt instruments of any maturity and does not seek to maintain a particular dollar-weighted average maturity. The Fund may invest in privately placed and other securities or instruments that are purchased and sold pursuant to Rule 144A or other exemptions under the Securities Act of 1933, as amended, subject to certain regulatory restrictions. The Fund may invest in derivatives, such as futures (including interest rate futures) to manage duration and yield curve exposure and to manage exposure to movements in interest rates. The Funds use of derivatives creates leverage (market exposure in excess of the Funds assets) in the Funds portfolio. The Fund may purchase or sell securities on a when-issued, delayed delivery or forward commitment basis. Such securities may include mortgage-backed securities acquired or sold in the to be announced (TBA) market and those in a dollar roll transaction. The Funds investment strategy may involve the frequent trading of portfolio securities. Show less
