MSBRX Investment Objective and Strategy
MassMutual Strategic Bond Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Massmutual Select Funds.
Investment objective
This Fund seeks a superior total rate of return by investing in fixed income instruments.
Principal investment strategy
Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in U.S. dollar-denominated fixed income securities and other debt instruments of domestic and foreign entities, including corporate bonds, securities issued or guaranteed as to principal or interest by the U.S. Government or its agencies or instrumentalities, mortgage-backed or asset-backed securities, and money market instruments. The Fund may invest up to 20% of its total assets in non-U.S. dollar-denominated securities of these entities. The Fund may also invest in emerging markets. The Fund may but will not necessarily engage in foreign currency transactions, including forward contracts, options on currency, futures contracts, and swap contracts, to attempt to seek to hedge or to protect against adverse changes in currency exchange rates.
In pursuing its investment objective, the Fund may (but is not obligated to) use a wide variety of additional exchange-traded and over-the-counter derivatives, including futures contracts (for hedging purposes or to adjust various portfolio characteristics, including the duration (interest rate volatility) of the Funds portfolio); interest rate swaps (for hedging purposes or to adjust various portfolio characteristics, including the duration (interest rate volatility) of the Funds portfolio); credit default swaps (for hedging purposes, to earn additional income, or as a substitute for direct investments); and hybrid instruments (as a substitute for direct investments). The Fund may also purchase and sell exchange-traded and over-the-counter options for hedging purposes, to adjust various portfolio characteristics, including the duration (interest rate volatility) of the Funds portfolio, or as a substitute for direct investments.
Use of derivatives by the Fund may create investment leverage. The Fund may also invest in money market securities, including commercial paper. The Fund may hold a portion of its assets in cash or cash equivalents. The Fund is managed by two subadvisers, each being responsible for a portion of the portfolio, but not necessarily equally weighted. The Fund invests primarily in investment grade securities (rated Baa or higher by Moodys or BBB or higher by Standard & Poors, or, if unrated, determined by the subadviser to be of comparable quality), but may invest up to 25% of the portfolio in below investment grade debt securities (junk or high yield bonds), including securities in default. In the event that a security is downgraded after its purchase by the Fund, the Fund may continue to hold the security if Western Asset Management Company (Western Asset), a subadviser of the Fund, considers that doing so would be consistent with the Funds investment objective.
The Fund may invest in domestic and foreign issuer loans and loan participations that pay interest at rates that float or reset periodically at a margin above a generally recognized base lending rate. Certain fixed income securities in which the Fund may invest pay interest at variable or floating rates. Variable rate securities tend to reset at specified intervals, while floating rate securities may reset upon a change in a specified index rate. In most cases, these reset provisions reduce the impact of changes in market interest rates on the value of the security. However, some securities do not track the underlying index directly, but reset based on formulas that may produce a leveraging effect; others may also provide for interest payments that vary inversely with market rates. The market prices of these securities may fluctuate significantly when interest rates change.
The Fund may invest in loans of companies whose financial condition is troubled or uncertain and that may be involved in bankruptcy proceedings, reorganizations, or financial restructurings. The Fund may also acquire, and subsequently hold, warrants and other equity interests. The Funds effective duration is normally expected to be between three and seven years. If the Funds effective duration falls outside of this range, the Fund will take action to bring it within its expected range within a reasonable period of time. Duration measures the price sensitivity of a bond to changes in interest rates. Duration is the dollar weighted average time to maturity of a bond utilizing the present value of all future cash flows. Effective duration measures the price sensitivity of a bond with embedded options to changes in interest rates.
It provides a more accurate measure of price volatility when, due to the embedded options, the cash flow characteristics of the bond change as interest rates shift. Western Asset invests in the fixed income markets seeking to exceed returns of the Funds benchmark while approximating benchmark risk. Western Asset focuses on sector allocation, issue selection, duration weighting, and term structure when buying and selling securities for the Fund. Western Asset emphasizes diversification, the use of multiple strategies and identification of long-term trends. The three key factors that determine the allocation decisions for the Fund are: Western Assets broad economic outlook, its review of historical yield spreads for debt instruments versus Treasuries, and its evaluation of changes in credit quality and the corresponding impact on prices.
Western Asset will determine the portion of the Funds assets to be allocated to non-U.S. dollar denominated securities from time to time. Western Asset Management Company Limited (Western Asset Limited), an affiliate of Western Asset, has subadvisory responsibility for Western Assets non-U.S. dollar denominated investments. Western Asset Limited will select such investments based on its consideration of factors such as relative interest rates, inflation rates, exchange rates, monetary and fiscal policies, and trade and current account balances. The Fund expects that it will engage in active and frequent trading and so will typically have a relatively high portfolio turnover rate.
