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 when 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.
Principal Investment Strategies of the Fund
The Low Duration Fund invests primarily in investment grade bonds and maintains an
average portfolio duration that is between 0 and 3 years. With respect to the Low Duration Fund’s investment objective, the Low Duration Fund’s benchmark is the ICE BofA 1-3 Year US Corporate & Government Index.
The Low Duration Fund normally invests at least 80% of its assets in debt securities. For the purposes of this strategy,
such debt securities include the following: obligations issued or guaranteed by the U.S. Government or a foreign government or their agencies, instrumentalities or political subdivisions; mortgage-backed securities, including agency
mortgage pass-through securities and commercial mortgage-backed securities; mortgage to-be-announced (“TBA”) securities; debt obligations of U.S. or foreign issuers; municipal securities; and asset-backed securities. The Fund’s investments in derivatives will be counted toward the Fund’s 80% policy to the extent that they provide investment
exposure to the securities included within that policy or to one or more market risk factors associated with such securities. The Low Duration Fund may invest up to 35% of its assets in non-investment grade bonds (commonly called
“high yield” or “junk bonds”). The Low Duration Fund may also invest up to 35% of its assets in assets of foreign issuers, of which 10% (as a percentage of the Low Duration Fund’s assets) may be invested in emerging markets
issuers. Up to 10% of the Low Duration Fund’s assets may be exposed to non-US currency risk. A bond of a foreign issuer, including an emerging market issuer, will not count toward the 10% limit on non-US currency exposure if the bond
is either (i) US dollar-denominated or (ii) non-US dollar-denominated, but hedged back to US dollars.
The management team evaluates sectors of the bond market and individual securities within these sectors. The management
team selects bonds from several sectors including: U.S. Treasuries and agency securities, commercial and residential mortgage-backed securities, collateralized mortgage
obligations (“CMOs”), asset-backed securities and corporate bonds.
The Low Duration Fund may buy or sell options or futures on a security or an index of securities, or enter into credit default swaps and interest rate or foreign currency transactions, including swaps (collectively, commonly known as
derivatives). The Low Duration Fund may use derivative instruments to hedge its investments or to seek to enhance returns. The Low Duration Fund may seek to obtain market exposure to the securities in which it primarily invests by
entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements and mortgage dollar rolls).
The Low Duration Fund may engage in active and frequent trading of portfolio securities to achieve its principal
investment strategies.
Principal Risks of Investing in the Fund
Risk is inherent in all investing. The value of your investment in the Fund, as well as
the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The following is a
summary description of principal risks of investing in the Fund. The relative significance of each risk factor below may change over time and you should review each risk factor carefully.
◼
Debt Securities Risk — Debt securities, such as bonds, involve risks, such as credit risk, interest rate risk, extension risk, and
prepayment risk, each of which are described in further detail below:
Credit Risk — Credit risk refers to the possibility that the
issuer of a debt security (i.e., the borrower) will not be able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the
market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.
Interest Rate Risk — The market value of bonds and other fixed-income securities changes in response to interest rate changes and
other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates
rise.
