Strategy. The Fund is an actively managed exchange-traded fund (ETF) that utilizes an investment process combining both macro and fundamental research by investing, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings, in mortgage-related debt and other securitized debt. The Fund seeks to achieve its investment objective by primarily investing in mortgage-related fixed income securities issued or guaranteed by the U.S. government or its agencies or instrumentalities (collectively, Agency Mortgage-Backed Securities), such as the Government National Mortgage Association (GNMA), the Federal National Mortgage Association (FNMA) or the Federal Home Loan Mortgage Corporation (FHLMC).

The Fund seeks to achieve its investment objective by primarily investing in mortgage-related fixed income securities issued or guaranteed by the U.S. government or its agencies or instrumentalities (collectively, Agency Mortgage-Backed Securities), such as the Government National Mortgage Association (GNMA), the Federal National Mortgage Association (FNMA) or the Federal Home Loan Mortgage Corporation (FHLMC). Agency Mortgage-Backed Securities include residential mortgage-backed securities, commercial mortgage-backed securities, and structured products such as collateralized mortgage obligations and real estate mortgage investment conduits (REMICs). The Fund may invest up to 20% of its net assets, plus the amount of any borrowings, in other securitized credit securities such as non-agency or privately issued residential and commercial mortgage-backed securities, asset-backed securities, collateralized loan obligations and credit risk transfer securities (collectively, Securitized Credit Securities). The Fund may purchase mortgage-backed securities through standardized contracts for future delivery in which the exact mortgage pools to be delivered are not specified until a few days prior to settlement, referred to as a to-be-announced transaction or TBA Transaction. In a TBA Transaction, the buyer and seller agree upon general trade parameters such as agency, settlement date, par amount and price. The actual pools delivered generally are determined two days prior to the settlement date and the Fund has the option to either accept delivery or roll into another TBA Transaction. The Fund, pending settlement of such TBA Transaction, will invest its assets in high quality, liquid short-term instruments such as U.S. Treasury securities, securities issued by government agencies, repurchase agreements and commercial paper. The universe of mortgage-related debt and other securitized debt currently includes securities that are rated investment grade as well as non-investment grade (commonly referred to as junk bonds or high yield bonds, which are considered to be speculative). The Fund intends to provide a broad-based exposure and therefore intends to invest in both investment grade and non-investment grade securities, but will not invest more than 20% of its net assets, plus the amount of any borrowings, in non-investment grade securities. Securities rated investment grade generally are considered to be of higher credit quality and subject to lower default risk. Although securities rated below investment grade may offer the potential for higher yields, they generally are subject to a higher potential risk of loss. The Fund may invest in securities of varying maturity or duration and with either fixed or adjustable rates. The Fund attempts to maintain an aggregate portfolio duration of up to seven years under normal market conditions. Aggregate portfolio duration is important to investors as an indication of the Funds sensitivity to changes in interest rates. The Funds actual portfolio duration may be longer or shorter depending on market conditions. The Funds investments in mortgage-related debt and other securitized debt may be represented by derivatives such as futures contracts. The Fund may invest in derivatives for various investment purposes, including to hedge interest rate risk, as a substitute for, or to gain exposure to, a position in an underlying asset, to reduce transaction costs, to maintain full market exposure ( i.e. , adjust investment characteristics to more closely approximate the characteristics of the market in which the Fund invests), to manage cash flows, or to preserve capital. The Funds use of derivatives will be collateralized by investments in liquid assets. Show less
