Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $25,000 in shares of the Sentinel Funds that include Class A shares. More information about these and other discounts is available from your financial professional and in the section entitled "Share Classes" on page 98 of the Fund's prospectus and "How to Purchase Shares and Reduce Sales Charges" on page 52 of the Fund's statement of additional information.

Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	5.00%	None
Maximum Deferred Sales Charge (Load)(as a percentage of purchase price or redemption proceeds, whichever is less)	None*	None

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

	Class A	Class I
Management Fee	0.70%	0.70%
Distribution and/or Service (12b-1) Fees	0.25%^	None
Other Expenses	0.34%	0.34%
Total Annual Fund Operating Expenses	1.29%	1.04%

* You pay a deferred sales charge of 1% on certain redemptions of Class A shares made within twelve months of purchase if you bought them without an initial sales charge as part of an investment of $1,000,000 or more.

^ 12b-1 fees have been restated to reflect a reduction in the maximum fee from 0.30% to 0.25% effective June 30, 2012. Because of this restatement, the Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets shown in the Fund's most recent annual report.

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. The Example assumes that you invest $10,000 in the Fund 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 Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Class	1 Year	3 Years	5 Years	10 Years
Class A	$625	$889	$1,172	$1,979
Class I	106	331	574	1,271

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 4% of the average value of its portfolio.

Principal Investment Strategies

The Fund normally invests at least 65% of its net assets in stocks of well-established U.S. companies, typically those above $5 billion in market capitalization. The Fund may invest without limitation in foreign securities.

Sentinel's investment philosophy centers on building a diverse portfolio consisting largely of securities of high quality companies with a positive multi-year outlook offered at attractive valuation levels, based on a number of metrics, including value relative to its history, peers and/or the market over time. The Fund may also invest in stocks with the potential to provide current income, growth of income and relatively low risk as compared to the stock market as a whole when consistent with the Fund's investment objective.

Up to 25% of the Fund's assets may be invested in securities within a single industry. Although the Fund may invest in any economic sector, at times it may emphasize one or more particular sectors. Sentinel has a preference for companies that earn above-average rates of return on capital and that generate free cash flow. Additionally, earnings revision trends are important.

The Fund may sell a security if the fundamentals of the company are deteriorating or the original investment premise is no longer valid, the stock is trading meaningfully higher than what the portfolio manager believes is a fair valuation, to manage the size of the holding or the sector weighting and/or to take advantage of a more attractive investment opportunity, and to meet redemptions. A security will also be sold if it is determined that it no longer meets the environmental, social and/or corporate governance performance criteria.

Sustainable and Responsible Investing. The Fund employs a process of environmental, social and corporate governance ("ESG") screening that is overseen by Sentinel's in-house sustainable research department. While no investment is ever made solely based on the qualitative criteria alone, the Fund believes sustainable screening provides a unique and more comprehensive view of the companies it considers for investment. Generally, companies are eliminated from investment consideration if they produce tobacco or tobacco products or alcoholic beverages; generate nuclear power or supply nuclear facilities with industry specific components, as a primary line of business; have material interests in the manufacture of weapons or weapons-specific components; are involved in gambling as a main line of business; and/or lack diversity at the level of the board of directors/senior management. The Fund favors companies that publish and enforce codes of conduct and vendor standards; promote equal opportunity, diversity and good employee relations; are sensitive to community concerns; seek alternatives to animal testing when not required by law; and/or have minimal impact on the environment and engage in proactive environmental initiatives.

Sentinel may, in its discretion, choose to apply additional screens, modify the application of the screens listed above or vary the application of the screens listed above to the Funds' investments at any time without shareholder approval.

For additional information on the environmental, social and governance screening process used by the Fund, please see "Additional Information About Each Fund – Investment Objectives and Strategies – Sentinel Sustainable Core Opportunities Fund – Principal Investment Strategies" at page 86 of the Prospectus.

Principal Investment Risks

• Foreign Banks and Securities Depositories Risk. Some foreign banks and securities depositories in which the Fund generally holds its foreign securities may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund's ability to recover its assets if a foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt.
• General Foreign Securities Risk. Investments in foreign securities may be affected unfavorably by changes in currency rates or exchange control regulations, or political and/or social instability in a particular foreign country or region.
• Investment Style Risk. The Fund uses a "blend" strategy to invest in both growth and value stocks, and/or in stocks with characteristics of both. This strategy may be out of favor at any particular time. The prices of growth stocks may fall dramatically if the company fails to meet earnings or revenue projections. The prices of value stocks may lag the stock market for long periods of time if the market fails to recognize the company's intrinsic worth.
• Sector Risk. Investments in a particular sector may trail returns from other economic sectors.
• Stock Market and Selection Risk. The stock market may go down in value, and may go down sharply and unpredictably. The stocks selected by the portfolio manager may underperform the stock market or other funds with similar investment objectives and investment strategies.
• Sustainable/Responsible Investing Risk. The Fund's environmental, social and corporate governance criteria may cause the Fund to forgo opportunities to buy certain securities, and/or forgo opportunities to gain exposure to certain industries, sectors, regions and countries. In addition, the Fund may be required to sell a security when it might otherwise be disadvantageous for it to do so.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year and by showing how the Fund's average annual returns for 1, 5 and 10 years compare with those of broad measures of market performance. The bar chart shows changes in the Fund's performance for Class A shares for each calendar year over a ten-year period. Sales charges are not reflected in the bar chart. If sales charges were reflected, returns would be less than those shown. However, the table includes, for share classes with a sales charge, the effect of the maximum sales charge. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund's results can be obtained by visiting www.sentinelinvestments.com.

The Sentinel Sustainable Core Opportunities Fund, which began operations on April 4, 2008, is a successor to the Citizens Value Fund, which was a successor to the Meyers Pride Value Fund, which began operations on June 13, 1996. Performance for the Class A shares of the Fund from September 24, 2001 to April 4, 2008 is based on the performance of the Standard shares of the predecessor Citizens Value Fund, which was offered without a sales charge and reflects the current maximum sales charge. Performance of the Class A shares from their inception on April 4, 2008 to June 29, 2012, has not been adjusted to reflect the lower maximum 12b-1 fee in effect prior to April 4, 2008 or the decrease in the maximum 12b-1 fee, effective June 30, 2012, from 0.30% to 0.25%. If it had, those returns would be higher.  Performance of the Class I shares from March 31, 2006 to April 4, 2008 (the inception date for the Class I shares) is based on the performance of the Institutional shares of the Citizens Value Fund, which had different expenses but substantially similar investment risks and from September 24, 2001 to March 31, 2006 is based on the performance of the Standard shares of the Citizens Value Fund.

1 The Russell 1000^® Index measures the performance of the large-cap segment of the U.S. equity universe. The Fund compares its performance to this index because Fund management believes it is an appropriate alternative measure of the Fund's investment strategy.

After-tax returns are calculated using the historical highest applicable individual federal marginal income tax rates in effect during the relevant period and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares and after-tax returns for other classes of shares will vary.
