Investment Objective

Long-term growth of capital.

Fees and Expenses of the Portfolio

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Portfolio. These fees and expenses are based on the year ended December 31, 2009, and are expressed as a percentage of the Portfolio’s average daily net assets over that period. The table and the Example below do not reflect the fees, expenses or withdrawal charges imposed by the Contracts. See the Contract prospectus for a description of those fees, expenses and charges. If Contract expenses were reflected, the fees and expenses in the table and Example would be higher.

Shareholder Fees (fees paid directly from your investment)—None

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

	Class A	Class B	Class E
Management Fee	0.83%	0.83%	0.83%
Distribution and Service (12b-1) Fees	None	0.25%	0.15%
Other Expenses	0.13%	0.13%	0.13%
Acquired Fund Fees and Expenses	0.03%	0.03%	0.03%
Total Annual Portfolio Operating Expenses	0.99%	1.24%	1.14%
Fee Waiver(1)	(0.03%)	(0.03%)	(0.03%)
Net Operating Expenses(1)	0.96%	1.21%	1.11%

(1) MetLife Advisers, LLC has contractually agreed, for the period May 1, 2010 through April 30, 2011, to reduce the Management Fee for each Class of the Portfolio to the annual rate of 0.81% for the first $500 million of the Portfolio’s average daily net assets and 0.78% for the next $500 million. This arrangement may be modified or discontinued prior to April 30, 2011, only with the approval of the Board of Directors of the Portfolio.

Example

The following Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio 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, that you reinvest all of your dividends and that the Portfolio’s operating expenses remain the same. The Example also assumes the expiration of the fee waiver agreement after one year. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

	Class A	Class B	Class E
1 Year	$98	$123	$113
3 Years	$312	$390	$359
5 Years	$544	$678	$625
10 Years	$1,210	$1,497	$1,383

Portfolio Turnover

The Portfolio 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. These costs, which are not reflected in annual portfolio operating expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 147% of the average value of its portfolio.

Principal Investment Strategies

Artio Global Management LLC (“Artio”), subadviser to the Portfolio, normally invests the Portfolio’s assets primarily in non-U.S. securities. The Portfolio normally invests at least 80% of its assets in stocks. Stocks include common stocks, preferred stocks and securities convertible into common or preferred stocks. The Portfolio normally invests in companies with a minimum market capitalization of $2.5 billion. The Portfolio normally invests in at least four different countries and at least 65% of its total assets in no fewer than three different countries outside the U.S. The Portfolio may also invest up to 25% of its total assets in emerging market securities.

The Portfolio may invest in American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”), International Depositary Receipts (“IDRs”), mutual funds, exchange-traded funds (“ETFs”), and real estate investment trusts (“REITs”).

The Portfolio may invest in derivatives for hedging and non-hedging purposes. The Portfolio typically uses derivatives as a substitute for taking a position in an underlying asset and/or as part of a strategy to reduce risk, such as interest rate risk, currency risk, and price risk. Such derivatives may include, but are not limited to, futures contracts, forward contracts, non-deliverable forwards, options, swaps and structured investments. The Portfolio may also invest in forward commitments and when-issued and delayed delivery securities.

Stock Selection

The Portfolio is not constrained by a particular investment style. It may invest in “growth” or “value” securities. Artio chooses securities in industries and companies whose products and services it believes are in demand. Artio considers for the Portfolio companies with above average earnings potential, companies that are dominant within their industries, companies within industries that are undergoing dramatic change, and companies that are market leaders in developing industries. Other considerations include expected levels of inflation, government policies or actions, currency values and prospects for economic growth in a country or region.

Artio selects stocks using a fundamental approach adjusted for factors specific to each region. For investments in developed markets, such as Western Europe, Australia, New Zealand and Canada, the stock selection process is primarily bottom-up, in which Artio concentrates on factors such as company balance sheets and industry performance relative to the broader economy. For investments in emerging markets, Artio uses a top-down selection process, focusing on the economic and political factors of particular areas. When selecting Japanese companies, Artio uses a combination of bottom-up and top-down analysis to best assess specific companies in the context of economic and political factors within Japan.

Primary Risks

As with all mutual funds, there is no guarantee that the Portfolio will achieve its investment objective. You could lose money by investing in the Portfolio. An investment in the Portfolio through a Contract is not a deposit or obligation of, or guaranteed by, any bank, and is not federally insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. Government.

The value of your investment in the Portfolio may be affected by one or more of the following risks, which are described in more detail in “Primary Risks of Investing in the Portfolio” in the Prospectus, any of which could cause the Portfolio’s return or the price of its shares to decrease or could cause the Portfolio’s yield to fluctuate. Please note that there are many other circumstances that could adversely affect your investment and prevent the Portfolio from reaching its objective, which are not described here.

Market Risk.    The Portfolio’s share price can fall because of, among other things, a decline in the market as a whole, deterioration in the prospects for a particular industry or company, or changes in general economic conditions, such as prevailing interest rates and investor sentiment. Significant disruptions to the financial markets could adversely affect the liquidity and volatility of securities held by the Portfolio.

Foreign Investment Risk.    Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social and economic developments abroad, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. To the extent foreign securities are denominated in foreign currencies, their values may be adversely affected by changes in currency exchange rates.

Emerging Markets Risk.    In addition to all of the risks of investing in foreign developed markets, emerging market securities involve risks attendant to less mature and stable governments and economies, lower trading volume, trading suspension, security price volatility, proceed repatriation restrictions, government confiscation, inflation, deflation, currency devaluation and adverse government regulations of industries or markets. As a result of these risks, the prices of emerging market securities tend to be more volatile than the securities of issuers located in developed markets.

Market Capitalization Risk.    Investing primarily in issuers in one market capitalization category (large, medium or small) carries the risk that due to current market conditions that category may be out of favor with investors. Larger, more established companies may be unable to respond quickly to new competitive challenges or attain the high growth rate of successful smaller companies. Stocks of smaller companies may be more volatile than those of larger companies due to, among other things, narrower product lines, more limited financial resources and fewer experienced managers. In addition, there is typically less publicly available information about small capitalization companies, and their stocks may have a more limited trading market than stocks of larger companies.

Derivatives Risk.    The Portfolio may invest in derivatives to obtain investment exposure, enhance return or “hedge” or protect its assets from an unfavorable shift in the value or rate of a reference instrument. Derivatives can significantly increase the Portfolio’s exposure to market risk, credit and counterparty risk (the risk that an issuer or counterparty will default or become less creditworthy) and other risks. Derivatives may be illiquid and difficult to value. Because of their complex nature, some derivatives may not perform as intended. As a result, the Portfolio may not realize the anticipated benefits from a derivative it holds or it may realize losses. Derivative transactions may create investment leverage, which may increase the Portfolio’s volatility

and may require the Portfolio to liquidate portfolio securities when it may not be advantageous to do so.

Investment Company and Exchange Traded Fund Risk.    An investment in an investment company or exchange-traded fund, or ETF, involves substantially the same risks as investing directly in the underlying securities. An investment company or ETF may not achieve its investment objective or execute its investment strategy effectively, which may adversely affect the Portfolio’s performance. The Portfolio must pay its pro rata portion of an investment company’s or ETF’s fees and expenses. Shares of a closed-end investment company or ETF may trade at a premium or discount to the net asset value of its portfolio securities.

Real Estate Investment Risk.    Investments in real estate investment trusts and other real estate related securities may be adversely impacted by the performance of the real estate market generally or that of a particular sub-sector or geographic region.

Convertible Securities Risk.    Investments in convertible securities may be subject to market risk, credit and counterparty risk (the risk that an issuer or counterparty will default or become less creditworthy), interest rate risk (the risk that the value of an investment in an income-producing security will decrease as interest rates rise) and other risks associated with investments in equity and fixed income securities, depending on the price of the underlying security and the conversion price. In addition, a convertible security may be bought back by the issuer at a time and a price that is disadvantageous to the Portfolio.

Forward Commitment, When-Issued and Delayed Delivery Securities Risk.    Investments in forward commitments and when-issued and delayed delivery securities are subject to the risk that the value or yield of the securities the Portfolio is obligated to purchase may decline below the agreed upon purchase price or expected yield before the securities are actually issued or delivered. These investments may create a form of investment leverage, which may increase the Portfolio’s volatility and may require the Portfolio to liquidate portfolio securities when it may not be advantageous to do so.

Past Performance

The information below shows the volatility of the Portfolio’s returns from year to year and how the Portfolio’s average annual returns over time compare with those of a broad-based securities market index. Both the bar chart and table assume reinvestment of dividends and distributions. Note that the results in the bar chart and table do not include the effect of Contract charges. If these Contract charges had been included, performance would have been lower. As with all mutual funds, past returns are not a prediction of future returns. On January 7, 2008, Artio (formerly, Julius Baer Investment Management LLC) succeeded Fidelity Management & Research Company (“FMR”) as subadviser to the Portfolio. On December 16, 2003, FMR succeeded Putnam Investment Management, LLC (“Putnam”) as subadviser to the Portfolio. On January 24, 2000, Putnam succeeded Santander Global Advisors, Inc. (“Santander”) as subadviser to the Portfolio. The performance information set forth below relates to the last ten full calendar years and, therefore, reflects the management of FMR, Putnam, Santander and Artio.

The bar chart below shows you the performance of the Portfolio’s Class A shares for the last ten full calendar years and indicates how it has varied from year to year. The Portfolio can also experience short-term performance swings as indicated in the high and low quarter information at the bottom of the chart.

Payments to Insurance Companies and Their Affiliates

The Portfolio is not sold directly to the general public but instead is offered as an underlying investment option for Contracts issued by insurance companies that are affiliated with the Portfolio and MetLife Advisers. As a result of these affiliations, the insurance companies may benefit more from offering the Portfolio as an investment option in the Contracts than offering other unaffiliated portfolios. The Portfolio and its related companies may also make payments to the sponsoring insurance companies (or their affiliates) for distribution and/or other services. The benefits to the insurance companies of offering the Portfolio over unaffiliated portfolios and these payments may be factors that the insurance companies consider in including the Portfolio as an underlying investment option in the Contracts and may create a conflict of interest. The prospectus for your Contract contains additional information about these payments.
