Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

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. It assumes that you invest $10,000 in each share class of the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. For Class A shares, the example includes the initial sales charge. The example also assumes that your investment earns a 5% return each year and that the Fund’s operating expenses are exactly as described in the preceding table. 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 the most recent fiscal year, the Fund’s portfolio turnover rate was 145% of the average value of its portfolio.

The Fund’s subadviser, Babson Capital Management LLC (“Babson Capital”), employs quantitative analysis to identify stocks included within the Index that it believes have the potential to outperform the Index over time, using a proprietary quantitative model that ranks all stocks included in the Index based on factors such as a company’s valuation, earnings quality, stock price momentum, and earnings improvement. Based on these rankings, Babson Capital seeks to construct a broadly diversified portfolio that it believes may have the potential to produce higher returns than the Index while maintaining risk characteristics similar to the Index. Babson Capital will typically adjust Index weights to: (1) overweight high-ranking stocks, (2) underweight low-ranking stocks (or not hold them at all), and (3) market weight stocks that do not have particularly high or low rankings. Babson Capital may also consider stocks not included in the Index but with similar market capitalizations. Babson Capital does not use market timing or macro-economic forecasting in constructing the Fund’s portfolio.

The Fund expects that it will engage in active and frequent trading and so will typically have a relatively high portfolio turnover rate.

to, the derivative may not have the effect anticipated. Many derivatives are traded in the over-the-counter market and not on exchanges.

Frequent Trading/Portfolio Turnover Risk Portfolio turnover generally involves some expense to the Fund and may result in the realization of taxable capital gains (including short-term gains). The trading costs and tax effects associated with portfolio turnover may adversely affect the Fund’s performance.

Indexing Risk The Fund’s performance may not track the performance of the index exactly due to a number of factors, including fees and expenses of the Fund, and the Fund’s cash positions.

Liquidity Risk  Certain securities may be difficult (or impossible) to sell or positions difficult to close out at a desirable time and price, and the Fund may be required to hold an investment that is declining in value or be prevented from realizing capital gains.

Management Risk The Fund relies on the manager’s ability to achieve its investment objective. There can be no assurance that the Fund will achieve the desired results and the Fund may incur significant losses.

Market Risk The value of the Fund’s portfolio securities may decline, at times sharply and unpredictably, as a result of unfavorable market-induced changes affecting particular industries, sectors, or issuers. Stock market prices in general may decline over short or extended periods, subjecting the Fund to unpredictable declines in the value of its shares and poor performance. The Fund is subject to risks affecting issuers, such as management performance, financial leverage, industry problems, and reduced demand for goods or services.

Valuation Risk The Fund is subject to the risk of mispricing or improper valuation of its investments, in particular to the extent that its securities are fair valued.

Value Company Risk The value investment approach entails the risk that the market will not recognize a security’s intrinsic value for a long time, or that a stock judged to be undervalued may actually be appropriately priced.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES
