Investment Objective

Maximum long-term capital growth.

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. The table and the Example below do not reflect the fees, expenses or withdrawal charges imposed by the Contracts. If Contract expenses were reflected, the fees and expenses in the table and Example would be higher. See the Contract prospectus for a description of those fees, expenses and charges.

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
Management Fee	0.75%
Distribution and/or Service (12b-1) Fees	None
Other Expenses*	0.08%
Total Annual Portfolio Operating Expenses	0.83%

* Other Expenses are based on estimated amounts for the current fiscal year.

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 and that the Portfolio’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

	1 Year		3 Years
Class A	$	85	$	266

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. While the Portfolio has not commenced operations prior to the date of this Prospectus, it is anticipated that the Portfolio’s turnover rate will typically not exceed 100%.

Principal Investment Strategies

Artisan Partners Limited Partnership (“Artisan” or “Subadviser”), subadviser to the Portfolio, invests, under normal market conditions, substantially all of the Portfolio’s assets in common stocks and similar securities, and invests at least 65% of the Portfolio’s net assets in securities of non-U.S. companies located in a minimum of four different countries. The Portfolio invests primarily in developed markets but also may invest up to 35% of its net assets in emerging and less developed markets. The Portfolio typically holds securities representing at least 15 countries. The maximum investment in any single country is 30% of the Portfolio’s net assets. The percentage limits above are measured using the market value of the Portfolio’s assets at the time of purchase.

Stock Selection

Artisan employs a fundamental stock selection process focused on identifying long-term growth opportunities to build a portfolio of non-U.S. growth companies of all market capitalizations. Artisan seeks to invest in companies within its preferred themes with sustainable growth characteristics at attractive valuations that do not fully reflect their long-term potential.

n Themes. Artisan identifies long-term secular (as opposed to cyclical) growth trends with the objective of investing in companies that have meaningful exposure to these trends. Artisan’s fundamental analysis focuses on those industry leaders with attractive growth and valuation characteristics that will be long-term beneficiaries of any structural change and/or trend.

n Sustainable Growth. Artisan applies a fundamental approach to identifying the long-term, sustainable growth characteristics of potential investments. Artisan seeks high-quality companies that typically have a sustainable competitive advantage, a superior business model, and a high-quality management team.

n Valuation. Artisan uses multiple valuation metrics to establish a target price range. Artisan assesses the relationship between its estimate of a company’s sustainable growth prospects and its current valuation.

Artisan constructs the portfolio without regard to index weightings. There are no restrictions on the size of the companies in which the Portfolio may invest. Artisan may sell a security when Artisan thinks the security is approaching full valuation, changing circumstances affect the original reasons for the security’s purchase, the company exhibits deteriorating fundamentals, or more attractive opportunities are identified by Artisan.

The Portfolio may invest up to 10% of its net assets, measured at the time of purchase, in equity-linked securities that provide economic exposure to a security of one or more non-U.S. companies without a direct investment in the underlying securities. These securities are sometimes referred to as “participation certificates.” Participation certificates typically are issued by a bank or broker-dealer. When a participation certificate is redeemed, the bank or broker-dealer is obligated to pay the Portfolio an amount based on the value of the underlying security or securities.

The Portfolio buys and sells non-U.S. currencies to facilitate transactions in portfolio securities because the Portfolio’s investments typically are traded in currencies other than U.S. dollars. Although the Portfolio usually does not hedge against possible variations in exchange rates, in limited circumstances, the Portfolio may hedge its exposure to a particular currency if the Portfolio has, or is initiating, positions in securities traded in that currency and Artisan believes that currency is overvalued. The Portfolio may buy and sell currencies for cash at current exchange rates, or it may use forward foreign currency exchange and foreign currency futures contracts to purchase or sell a specified currency at a specified future date or within a specified time period, at a price set at the time of the contract.

The Portfolio tries to maintain a cash position of no more than 5% of its net assets, although cash flows, including from contract owners’ purchases and sales of Portfolio shares and the Portfolio’s purchases and sales of portfolio securities, may cause the Portfolio’s cash position to be larger or smaller. As a result, the Portfolio may at times hold more than 5% of its net assets in cash.

Principal 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 “Principal Risks of Investing in the Portfolio” in the Prospectus, any of which could cause the Portfolio’s return, the price of the Portfolio’s shares or the Portfolio’s yield to fluctuate.

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 or 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.

Investment Style Risk.    Different investment styles such as growth or value tend to shift in and out of favor, depending on market and economic conditions as well as investor sentiment. The Portfolio may outperform or underperform other funds that employ a different investment style.

Focused Investment Risk.    Substantial investments in a particular market, industry, group of industries, country, region, group of countries, asset class or sector make the Portfolio’s performance more susceptible to any single economic, market, political or regulatory occurrence affecting that particular market, industry, group of industries, country, region, group of countries, asset class or sector than a portfolio that invests more broadly.

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.

Past Performance

Prior to the date of this Prospectus, the Portfolio had not commenced operations. No performance information is currently available.

Adviser.    MetLife Advisers, LLC (“MetLife Advisers”) is the Portfolio’s investment adviser.

Purchase and Sale of Portfolio Shares

Shares of the Portfolio are only sold to separate accounts of Metropolitan Life Insurance Company and its affiliates to fund Contracts. For information regarding the purchase and sale of the Portfolio’s shares, please see the prospectus for the relevant Contract.

Tax Information

For information regarding the tax consequences of Contract ownership, please see the prospectus for the relevant Contract.

Payments to Broker-Dealers and Other Financial Intermediaries

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.
