Expense example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment in the fund for the time periods indicated (Kept column) and then assuming a redemption of all of your shares at the end of those periods (Sold column). The example assumes a 5% average annual return. The example assumes fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

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 fund 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 its most recent fiscal year, the fund’s portfolio turnover rate was 65% of the average value of its portfolio.

Principal investment strategies

Under normal market conditions, the fund invests at least 25% of assets in equity securities and at least 25% of assets in senior debt securities. The fund allocates its investments among a diversified mix of debt and equity securities.

With regard to the fund's equity securities, the subadviser looks for companies that appear to be undervalued compared to their historical valuations relative to the market. The subadviser uses fundamental financial analysis and proprietary financial models to identify companies of any size that are selling at a discount as measured by ratios such as price-to-book, price-to-earnings and price-to-sales.

The subadviser then looks for a positive catalyst in a company's near-term outlook that it believes will accelerate earnings or improve the value of the company's assets. These positive catalysts may include, but are not limited to: new, improved or unique products or services; new or rapidly expanding markets for the company's products; new management; changes in the economic, financial, political or regulatory environment affecting the company; or a business strategy not recognized by the marketplace. The subadviser also considers an issuer's dividend-paying prospects and overall financial strength.

The fund's debt securities are used to enhance current income and provide some added stability. The fund's investments in bonds of any maturity are primarily investment grade (rated BBB or above by Standard & Poor's Ratings Services (S&P) or Baa or above by Moody's Investors Service, Inc. (Moody's) and their unrated equivalents). However, up to 20% of assets may be in below investment-grade bonds (i.e., "junk bonds") rated as low as C by S&P or Moody's and their unrated equivalents.

Although the fund invests primarily in U.S. securities, it may invest up to 35% of assets in foreign securities. The fund may, to a limited extent, engage in derivatives transactions that include futures contracts, options and foreign currency forward contracts, in each case for the purposes of reducing risk and/or obtaining efficient market exposure. The fund may invest up to 50% of assets in mortgage-backed securities.

Principal risks

An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund's shares will go up and down in price, meaning that you could lose money by investing in the fund. Many factors influence a mutual fund's performance.

Instability in the financial markets has led many governments, including the United States government, to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility and, in some cases, a lack of liquidity. Federal, state and other governments, and their regulatory agencies or self-regulatory organizations, may take actions that affect the regulation of the instruments in which the fund invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which the fund itself is regulated. Such legislation or regulation could limit or preclude the fund's ability to achieve its investment objective.

Governments or their agencies may also acquire distressed assets from financial institutions and acquire ownership interests in those institutions. The implications of government ownership and disposition of these assets are unclear, and such a program may have positive or negative effects on the liquidity, valuation and performance of the fund's portfolio holdings. Furthermore, volatile financial markets can expose the fund to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the fund.

The fund's main risk factors are listed below in alphabetical order. Before investing, be sure to read the additional descriptions of these risks beginning on page 6 of the prospectus.

Active management risk The subadviser's investment strategy may fail to produce the intended result.

Equity securities risk The value of a company's equity securities is subject to changes in the company's financial condition, and overall market and economic conditions. The securities of value companies are subject to the risk that the companies may not overcome the adverse business developments or other factors causing their securities to be underpriced or that the market may never come to recognize their fundamental value.

Fixed-income securities risk Fixed-income securities are affected by changes in interest rates and credit quality. A rise in interest rates typically causes bond prices to fall. The longer the average maturity of the bonds held by the fund, the more sensitive the fund is likely to be to interest-rate changes. There is the possibility that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments.

Foreign securities risk As compared to U.S. companies, there may be less publicly available information relating to foreign companies. Foreign securities may be subject to foreign taxes. The value of foreign securities is subject to currency fluctuations and adverse political and economic developments.

Hedging, derivatives and other strategic transactions risk Hedging and other strategic transactions may increase the volatility of a fund and, if the transaction is not successful, could result in a significant loss to a fund. The use of derivative instruments could produce disproportionate gains or losses, more than the principal amount invested. Investing in derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and, in a down market, could become harder to value or sell at a fair price. The following is a list of certain derivatives and other strategic transactions in which the fund intends to invest and the main risks associated with each of them:

Foreign currency forward contracts Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions), foreign currency risk and risk of disproportionate loss are the principal risks of engaging in transactions involving foreign currency forward contracts.

Futures contracts Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions) and risk of disproportionate loss are the principal risks of engaging in transactions involving futures contracts.

Options Counterparty risk, liquidity risk (i.e., the inability to enter into closing transactions) and risk of disproportionate loss are the principal risks of engaging in transactions involving options. Counterparty risk does not apply to exchange-traded options.

Large company risk Large-capitalization stocks as a group could fall out of favor with the market, causing the fund to underperform investments that focus on small- or medium-capitalization stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies. For purposes of the fund's investment policies, the market capitalization of a company is based on its market capitalization at the time the fund purchases the company's securities. Market capitalizations of companies change over time.

Liquidity risk Exposure exists when trading volume, lack of a market maker or legal restrictions impair the ability to sell particular securities or close derivative positions at an advantageous price.

Lower-rated fixed-income securities risk and high-yield securities risk Lower-rated fixed-income securities and high-yield fixed-income securities (commonly known as "junk bonds") are subject to greater credit quality risk and risk of default than higher-rated fixed-income securities. These securities may be considered speculative and the value of these securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market or economic developments and can be difficult to resell.

Medium and smaller company risk The prices of medium and smaller company stocks can change more frequently and dramatically than those of large company stocks. For purposes of the fund's investment policies, the market capitalization of a company is based on its market capitalization at the time the fund purchases the company's securities. Market capitalizations of companies change over time.

Mortgage-backed and asset-backed securities risk Different types of mortgage-backed securities and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate and/or other market risks.

Sector risk Because the fund may from time to time focus on one or more sectors of the economy, at such times its performance will depend in large part on the performance of those sectors. A fund that invests in particular sectors is particularly susceptible to the impact of market, economic, regulatory and other factors affecting those sectors. As a result, at such times, the value of your investment may fluctuate more widely than it would in a fund that is invested across sectors.
