Market Vectors Nigeria-Focused West Africa ETF

RISK/RETURN

Investment Objective

Market Vectors Nigeria-Focused West Africa ETF (the “Fund”) seeks to replicate as closely as possible, before fees and expenses, the price and yield performance of the Market Vectors Nigeria-Focused West Africa Index (the “Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”).

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees (USD $)	Market Vectors Nigeria-Focused West Africa ETF
Shareholder Fees (fees paid directly from your investment)	none

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

Operating Expenses		Market Vectors Nigeria-Focused West Africa ETF
Management Fee		0.50%
Other Expenses	[1]	0.28%
Total Annual Fund Operating Expenses	[2]	0.78%
Fee Waivers and Expense Reimbursement	[2]	0.09%
Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursement	[2]	0.69%

Expense Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

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% annual return 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:

Expense Example (USD $)	Market Vectors Nigeria-Focused West Africa ETF

Portfolio Turnover

The Fund will pay transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover will cause the Fund to incur additional 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, may affect the Fund’s performance. Because the Fund is newly organized, no portfolio turnover figures are available.

Principal Investment Strategies

The Fund normally invests at least 80% of its total assets in securities that comprise the Fund’s benchmark index. The Index consists of equity securities of companies that are domiciled and primarily listed on an exchange in West Africa or that generate at least 50% of their revenues in West Africa. The Index Provider considers the following countries to be in West Africa: Benin, Burkina Faso, Cape Verde, Cote d’Ivoire, The Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Mauretania, Niger, Nigeria, Senegal, Sierra Leone and Togo. As of each quarterly rebalance, at least 40% of the Index will consist of securities of companies that are domiciled and primarily listed on an exchange in Nigeria or that generate at least 50% of their revenues in Nigeria. As of the date of this Prospectus, approximately 50% of the Index consisted of securities of such companies. This percentage is subject to change. Such companies may include small- and medium-capitalization companies. The Fund’s 80% investment policy is non-fundamental and requires 60 days’ prior written notice to shareholders before it can be changed.

The Fund, using a “passive” or indexing investment approach, attempts to approximate the investment performance of the Index by investing in a portfolio of securities that generally replicates the Index. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index before fees and expenses will be 95% or better. A figure of 100% would indicate perfect correlation.

The Fund will concentrate its investments in a particular industry or group of industries to the extent that the Index concentrates in an industry or group of industries. As of the date of this Prospectus, the following Index is concentrated in the basic materials and financial services sectors and the energy sector represents a significant portion of the Index.

Principal Risks of Investing in the Fund

Investors in the Fund should be willing to accept a high degree of volatility in the price of the Fund’s Shares and the possibility of significant losses. An investment in the Fund involves a substantial degree of risk. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Therefore, you should consider carefully the following risks before investing in the Fund.

Special Risk Considerations of Investing in West African Issuers. Investment in securities of West African issuers involves risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. Such heightened risks include, among others, expropriation and/or nationalization of assets, restrictions on and government intervention in international trade, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision making, armed conflict, the impact on the economy as a result of civil war, and social instability as a result of religious, ethnic and/or socioeconomic unrest.

The securities markets in West Africa are underdeveloped and are often considered to be less correlated to global economic cycles than those markets located in more developed countries. As a result, securities markets in West Africa are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations, uncertainty regarding the existence of trading markets, governmental control and heavy regulation of labor and industry. Moreover, trading on securities markets may be suspended altogether.

Certain West African governments may restrict or control to varying degrees the ability of foreign investors to invest in securities of issuers located or operating in West Africa. Moreover, certain countries in West Africa may require governmental approval prior to investments by foreign investors in companies involved in crude oil drilling, production of military equipment and certain other industries.

This may limit or prevent foreign investment in securities of such companies. In addition, foreign investors may be subject to additional taxes. These factors, among others, make investing in issuers located or operating in West Africa significantly riskier than investing in issuers located or operating in more developed countries, and any one of them could cause a decline in the value of the Fund’s Shares.

The value of certain West African currencies may be subject to a high degree of fluctuation. The Fund’s assets will be invested primarily in equity securities of West African companies and the income received by the Fund will be principally in West African currencies. The Fund’s exposure to West African currencies and changes in value of West African currencies versus the U.S. dollar may result in reduced returns for the Fund. Moreover, the Fund may incur costs in connection with conversions between U.S. dollars and West African currencies.

Special Risk Considerations for Investing in Nigerian Issuers. The Nigerian economy has experienced high interest rates, economic volatility, inflation, currency devaluations and high unemployment rates, all of which could negatively affect the value of companies located in Nigeria and the value of your investment in the Fund. In addition, commodities represent a significant percentage of Nigeria’s exports and its economy is particularly sensitive to fluctuations in commodity prices. Oil and natural gas exports account for a substantial portion of Nigeria’s exports. Delays or stoppages in drilling operations or production or fluctuations in the commodity markets could have an adverse impact on Nigeria’s economy and companies located in Nigeria. Adverse economic events in the economies of Europe and the United States, which are key trading partners, may have a significant adverse effect on Nigeria’s economy and companies located in Nigeria.

Risk of Investing in Foreign Securities. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. These additional risks include greater market volatility, the availability of less reliable financial information, higher transactional and custody costs, taxation by foreign governments, decreased market liquidity and political instability. In addition, the Fund may invest in depositary receipts which involve similar risks to those associated with investments in foreign securities.

Risk of Investing in Frontier and Emerging Market Countries. West African countries are considered to be “frontier markets.” Frontier and emerging market countries generally have smaller economies and less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in frontier and emerging market countries are magnified. Investments in securities of issuers located in frontier and emerging market countries are exposed to a number of risks that may make these investments volatile in price or difficult to trade. Political risks may include unstable governments, nationalization, restrictions on foreign ownership, laws that prevent investors from getting their money out of a country and legal systems that do not protect property rights as well as the laws of the United States. Market risks may include economies that concentrate in only a few industries, securities issues that are held by only a few investors, limited trading capacity in local exchanges and the possibility that markets or issues may be manipulated by foreign nationals who have inside information.

Risk of Investing in Depositary Receipts. Depositary receipts in which the Fund may invest are receipts issued by banks or trust companies that entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Investments in depositary receipts may be less liquid than the underlying shares in their primary trading market and may negatively affect the Fund’s ability to replicate the performance of the Index.

Risk of Investing in the Basic Materials Sector. The basic materials sector includes companies that manufacture chemicals, construction materials, glass and paper products, as well as metals, minerals and mining companies. To the extent the Index includes securities of issuers in the basic materials sector, the Fund will invest in companies in such sector. As such, the Fund will be sensitive to changes in, and its performance will depend to a greater extent on, the overall condition of the basic materials sector. Companies engaged in the production and distribution of basic materials may be adversely affected by changes in world events, political and economic conditions, energy conservation, environmental policies, commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources and labor relations.

Risks of Investing in the Financial Services Sector. The financial services sector includes companies involved in such activities as banking, commercial and consumer finance, investment banking, brokerage, asset management, custody and insurance. To the extent the Index includes securities of issuers in the financial services sector, the Fund will invest in companies in such sector. As such, the Fund will be sensitive to changes in, and its performance will depend to a greater extent on, the overall condition of the financial services sector. Companies in the financial services sector may be subject to extensive government regulation that affects the scope of their activities, the prices they can charge and the amount of capital they must maintain.

Risk of Investing in the Energy Sector. The energy sector includes companies engaged in the exploration, production and distribution of energy sources and companies that manufacture or provide related equipment or services. To the extent the Index includes securities of issuers in the energy sector, the Fund will be sensitive to changes in, and its performance will depend to a greater extent on, the overall condition of the energy sector. Companies operating in the energy sector are subject to risks including, but not limited to, economic growth, worldwide demand, political instability in the regions that the companies operate, government regulation stipulating rates charged by utilities, interest rate sensitivity, oil price volatility and the cost of providing the specific utility services. In addition, these companies are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism and natural disasters.

Risk of Investing in Small- and Medium-Capitalization Companies. Small- and medium-capitalization companies may be more volatile and more likely than large-capitalization companies to have narrower product lines, fewer financial resources, less management depth and experience and less competitive strength. Returns on investments in securities of these companies could trail the returns on investments in securities of larger companies.

Market Risk. The prices of the securities in the Fund are subject to the risks associated with investing in the securities market, including general economic conditions and sudden and unpredictable drops in value. An investment in the Fund may lose money.

Index Tracking Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index and incurs costs associated with buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index and raising cash to meet redemptions or deploying cash in connection with newly created Creation Units (defined herein). Because the Fund bears the costs and risks associated with buying and selling securities while such costs and risks are not factored into the return of the Index, the Fund’s return may deviate significantly from the return of the Index. In addition, the Fund may not be able to invest in certain securities included in the Index, or invest in them in the exact proportions in which they are represented in the Index, due to legal restrictions or limitations imposed by West African governments or a lack of liquidity on stock exchanges in which such securities trade. The Fund is expected to value certain of its investments based on fair value prices. To the extent the Fund calculates its net asset value (“NAV”) based on fair value prices and the value of the Index is based on securities’ closing price on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

Replication Management Risk. An investment in the Fund involves risks similar to those of investing in any fund of equity securities traded on an exchange, such as market fluctuations caused by such factors as economic and political developments, changes in interest rates and perceived trends in security prices. However, because the Fund is not “actively” managed, unless a specific security is removed from the Index, the Fund generally would not sell a security because the security’s issuer was in financial trouble. Therefore, the Fund’s performance could be lower than other types of mutual funds that may actively shift their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline or a decline in the value of one or more issuers.

Risk of Cash Transactions. Unlike most other exchange-traded funds (“ETFs”), the Fund expects to effect all of its creations and redemptions for cash, rather than in-kind securities. As such, investments in Shares may be less tax-efficient than an investment in a conventional ETF.

Non-Diversified Risk. The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940, as amended (“1940 Act”). Therefore, the Fund may invest a relatively high percentage of its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single company. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Concentration Risk. The Fund’s assets will be concentrated in a particular sector or sectors or industry or group of industries to the extent the Index concentrates in a particular sector or sectors or industry or group of industries. To the extent that the Fund’s investments are concentrated in a particular sector or industry, the Fund will be susceptible to loss due to adverse occurrences affecting that sector or industry.

Performance

The Fund has not yet commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at vaneck.com/etf.

[1] "Other Expenses" are based on estimated amounts for the current fiscal year.

[2] Van Eck Associates Corporation (the "Adviser") has agreed to waive fees and/or pay Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expense, offering costs, trading expenses, taxes and extraordinary expenses) from exceeding 0.69% of the Fund's average daily net assets per year until at least May 1, 2013. During such time, the expense limitation is expected to continue until the Fund's Board of Trustees acts to discontinue all or a portion of such expense limitation.

To the extent the Fund calculates its net asset value (“NAV”) based on fair value prices and the value of the Index is based on securities’ closing price on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

Replication Management Risk. An investment in the Fund involves risks similar to those of investing in any fund of equity securities traded on an exchange, such as market fluctuations caused by such factors as economic and political developments, changes in interest rates and perceived trends in security prices. However, because the Fund is not “actively” managed, unless a specific security is removed from the Index, the Fund generally would not sell a security because the security’s issuer was in financial trouble. Therefore, the Fund’s performance could be lower than other types of mutual funds that may actively shift their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline or a decline in the value of one or more issuers.

Risk of Cash Transactions. Unlike most other exchange-traded funds (“ETFs”), the Fund expects to effect all of its creations and redemptions for cash, rather than in-kind securities. As such, investments in Shares may be less tax-efficient than an investment in a conventional ETF.

Non-Diversified Risk. The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940, as amended (“1940 Act”). Therefore, the Fund may invest a relatively high percentage of its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single company. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Concentration Risk. The Fund’s assets will be concentrated in a particular sector or sectors or industry or group of industries to the extent the Index concentrates in a particular sector or sectors or industry or group of industries. To the extent that the Fund’s investments are concentrated in a particular sector or industry, the Fund will be susceptible to loss due to adverse occurrences affecting that sector or industry.
