Example

The Example below is intended to help you compare the cost of investing in the Series with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Series for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Series’ operating expenses remain the same (taking into account the Advisor's contractual waiver). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Series pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Series shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the performance of the Series.

Principal Investment Strategies

The Series will invest, under normal circumstances, at least 80% of its net assets in credit-related instruments and other financial instruments, principally derivative instruments and exchange-traded funds (ETFs), with economic characteristics similar to credit-related instruments. For purposes of this policy, credit-related instruments may include U.S. dollar denominated fixed income securities issued by U.S. corporations, foreign corporations (e.g., yankee bonds), U.S. Government agencies or instrumentalities, foreign governments or their agencies or instrumentalities (e.g., the Korean Development Bank) and supranational entities (e.g., the World Bank); convertible securities; mortgage-backed and asset-backed securities; and taxable municipal bonds.

The mortgage- and asset-backed securities in which the Series principally invests are issued by U.S. Government agencies (such as GNMA, FNMA, and FHLMC) and private issuers and entitle the holders to a pro rata share of the cash flows generated by the instruments underlying the security (principally residential and commercial mortgages, credit card receivables and car loans).

The Series may purchase shares of ETFs, including to establish a diversified position in a particular market sector or to manage cash flows. The Advisor believes that purchasing ETFs may allow it to manage the Series’ portfolio more efficiently than would otherwise be possible.

The Series may invest in fixed income index futures for cash management purposes.

Fixed Income Securities Selection Process — When investing in fixed income securities, the Advisor attempts to identify sectors, as well as individual securities within those sectors, that offer yields and credit spreads sufficient to compensate the Series for the risks specific to a given sector or security. A credit spread is the difference between the yield of a U.S. Treasury security and the yield of another fixed income security with a similar maturity. When investing in mortgage- and asset-backed securities, the Advisor also considers the prepayment speeds of the securities. Prepayment speed is the estimated rate at which borrowers will pay off the underlying loans ahead of schedule.

In analyzing the relative attractiveness of sectors and/or individual securities, the Advisor considers:

• The relevant economic conditions and sector trends.

• The interest rate sensitivities of the particular sectors and securities.

• The yield differentials across sectors, credit qualities, asset-backed security types, and maturities.

• “Bottom-up” factors such as issuer-specific credit metrics for corporate bonds and scenario analysis, collateral-level analysis, and issuer/servicer analysis for mortgage- and asset-backed securities.

Maturity and Portfolio Duration — The Series is not subject to any maturity or duration restrictions but will vary its average dollar weighted portfolio maturity and duration depending on the Advisor’s outlook for yields. For example, the Advisor may invest in longer-term bonds when it expects yields to fall in order to realize gains for the Series. Likewise, the Advisor may invest in shorter-term bonds when it expects yields to rise. Duration is a measure of the expected life of a fixed income security that is used to determine the sensitivity of a security’s price to changes in yields. The prices of fixed income securities with shorter durations generally will be less affected by changes in yields than the prices of fixed income securities with longer durations. For example, a 10 year duration means the fixed income security will decrease in value by 10% if yields rise 1% and increase in value by 10% if yields fall 1%.

Credit Quality — The Series will principally invest in investment grade securities, those securities rated BBB- or above by S&P or Baa3 or above by Moody’s (or determined to be of equivalent quality by the Advisor). If a security purchased by the Series is downgraded below investment grade after purchase, the Advisor will review the security to determine if it remains an appropriate investment.

The Series may engage in active and frequent trading of portfolio securities. If it does, its portfolio turnover rate and transaction costs will rise, which may lower fund performance and may increase the likelihood of capital gain distributions.

A security may be sold for one or more of the following reasons:

• it no longer meets the selection criteria under which it was purchased;

• its relative value has declined (the spread has tightened such that the security is no longer considered attractively priced);

• a more attractive investment opportunity is identified.

There are no prescribed limits on the sector allocation of the Series’ investments and, from time to time, the Series may focus its investments in one or more sectors.

The Series is classified as “non-diversified,” which means that it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund.

Principal Risks of Investing in the Series

As with all mutual funds, there is no guarantee that the Series will achieve its investment objective. You could lose money by investing in the Series.

Management risk — The value of your investment may decline if the Advisor’s judgments about the attractiveness, relative value or potential appreciation of a particular security or strategy prove to be incorrect.

Market risk — Because the Series invests in fixed income securities, the value of your investment will fluctuate in response to changes in interest rates and credit spreads, even though such changes will not affect the interest income derived from portfolio securities. The value of your investment will also fluctuate in response to changes in repayment speeds. You could lose money on your investment in the Series or the Series could underperform if any of the following occurs:

• U.S. and/or foreign bond markets decline.

• The issuer of a corporate bond owned by the Series defaults on its obligation to pay principal and/or interest or has its credit rating downgraded; this risk is greater for lower quality bonds.

• Interest rates rise and/or credit spreads widen. These events alone or in combination can cause bond prices to fall and reduce the value of the Series’ portfolio. Longer-term bonds have greater sensitivity to, and will therefore experience greater fluctuations in response to, interest rate changes than shorter-term bonds.

• The issuers of high interest debt obligations pay off the debts earlier than expected when interest rates fall, and the Series has to reinvest the proceeds at lower yields (prepayment risk), or the issuers of lower interest rate debt obligations pay off the debts later than expected when interest rates rise, thus keeping the Series’ assets tied up in lower yield debt obligations (extension risk).

Current market conditions may pose heightened risks for the Series. While interest rates in the U.S. are near historic lows, recent changes in government policy, including the Federal Reserve ending its quantitative easing program and raising the federal funds rate, have increased the risk that interest rates will continue to rise in the near future. An increase in interest rates may, in turn, increase volatility and reduce liquidity in the fixed income markets, and result in a decline in the value of the fixed income investments held by the Series. In addition, reductions in dealer market-making capacity as a result of structural or regulatory changes could further decrease liquidity and/or increase volatility in the fixed income markets. As a result of these conditions, the Series’ value may fluctuate and/or the Series may experience increased redemptions from shareholders, which may impact the Series’ liquidity or force the Series to sell securities into a declining or illiquid market.

Foreign securities risk — Because the Series may invest in securities of foreign issuers, the Series is subject to additional risks. These include risks of adverse changes in foreign economic, political, regulatory and other conditions. The prices of foreign fixed income securities may, at times, move in a different direction than the prices of fixed income securities issued in the United States.

Risks related to ETFs — The risks of owning shares of an ETF generally reflect the risks of owning the underlying securities the ETF is designed to track, although lack of liquidity in an ETF could result in its value being more volatile than the underlying portfolio of securities. The Series will also bear its proportionate share of the expenses of the purchased ETF in addition to its own expenses.

Convertible securities risk — The Series’ investments in convertible securities are subject to interest rate risk and credit risk, similar to fixed income securities. In addition, they are also subject to the risk that the price of the underlying common stock will go down, which may cause a proportionate (or disproportionate) decline in the price of the convertible security.

U.S. Government securities risk — Although U.S. Government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates. Obligations issued by some U.S. Government agencies are backed by the U.S. Treasury, while others are backed solely by the ability of the agency to borrow from the U.S. Treasury or by the agency’s own resources, and, therefore, such obligations are not backed by the full faith and credit of the United States government.

Mortgage- and asset-backed securities risks — The Series' investments in mortgage-backed and asset-backed securities may subject it to the following additional risks:

• Mortgage-backed securities are affected by, among other things, interest rate changes and the possibility of prepayment of the underlying mortgage loans. Mortgage-backed securities are also subject to the risk that underlying borrowers will be unable to meet their obligations.

• Payment of principal and interest on asset-backed securities is dependent largely on the cash flows generated by the assets backing the securities, and asset-backed securities may not have the benefit of any security interest in the related assets.

Risks of lower-rated investment grade securities — Securities with the lowest ratings within the investment grade categories carry more risk than those with the highest ratings. When a Series invests in securities in the lower rating categories, the achievement of its goals is more dependent on the Advisor’s ability than would be the case if the Series were to invest in higher-rated securities within the investment grade categories.

The Advisor seeks to minimize this risk through investment analysis and attention to current developments in interest rates and economic conditions.

Municipal bond risk — The Series’ investments in municipal bonds may subject it to the following additional risks:

• Changes in the financial condition of municipal issuers may adversely affect the value of the Series’ securities.

• Economic or political changes may affect the ability of issuers of municipal securities to repay principal and to make interest payments on securities owned by the Series.

• Poor statewide or local economic results or changing political sentiments may reduce tax revenues and increase the expenses of municipal issuers, making it more difficult for them to meet their obligations.

Futures risk – The Series is subject to the following risks due to its ability to invest in futures:

• Futures, like all derivatives, can be extremely sensitive to changes in the market value of the underlying investment, and changes in the value of a futures contract may not correlate perfectly with the underlying investment.

• The Series may not be able to receive amounts payable to it under its futures contracts as quickly as it may be able to sell or otherwise obtain payments from other investments, so the Series’ investments in such contracts may not be as liquid as the Series’ other investments.

Sector focus risk — Because the Series' investments may, from time to time, be more heavily invested in a particular sector or sectors, the value of its shares may be especially sensitive to factors and economic risks that specifically affect those sectors. As a result, the Series' share price may fluctuate more widely than the value of shares of a mutual fund that invests in a broader range of sectors.

Non-diversification risk — The Series is non-diversified, which means that it may invest in the securities of relatively few issuers. As a result, the Series may be susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, and may experience increased volatility due to its investments in those securities.

Portfolio turnover risk — The Series is subject to portfolio turnover risk because it may engage in active and frequent trading of portfolio securities. Such a strategy often involves higher expenses, including brokerage commissions, and may increase the amount of capital gains (in particular, short term gains) realized by the Series. Shareholders may pay tax on such capital gains.

Liquidity risk — The Series is subject to the risk that, at certain times, its securities may be difficult or impossible to sell at the time and the price that the Series would like. The Series may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on the Series’ management or performance.

Large redemption risk — Certain institutions or individuals may from time to time own (beneficially or of record) or control a significant percentage of the Series’ shares. Redemptions by these institutions or individuals in the Series may impact the Series’ liquidity and net asset value (NAV). These redemptions may also force the Series to sell securities, which may cause the Series to experience a loss (particularly during periods of declining or illiquid markets), as well as cause the Series’ portfolio turnover rate and transaction costs to rise, which may negatively affect the Series’ performance and increase the likelihood of capital gain distributions for remaining shareholders.

The risks above could contribute to a decline in the value of the Series’ investments and, consequently, the share price of the Series.
