Market Vectors Mortgage REIT Income ETF

RISK/RETURN

Investment Objective

Market Vectors Mortgage REIT Income ETF (the “Fund”) seeks to replicate as closely as possible, before fees and expenses, the price and yield performance of the Market Vectors® Global Mortgage REITs 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.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees (USD $)	Market Vectors Mortgage REIT Income 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)

Annual Fund Operating Expenses		Market Vectors Mortgage REIT Income ETF
Management Fee		0.40%
Other Expenses	[1]	0.12%
Total Annual Fund Operating Expenses	[2]	0.52%
Fee Waivers and Expense Reimbursement	[2]	0.12%
Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursement	[2]	0.40%

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 $)	1	3
Market Vectors Mortgage REIT Income ETF	41	155

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. While publicly traded U.S. and non-U.S. mortgage real estate investment trusts (“REITs”) that derive at least 50% of their revenues from mortgage-related activity are eligible for inclusion in the Index, as of the date of this Prospectus, the Index is comprised of stocks of publicly traded U.S. mortgage REITs that derive at least 50% of their revenues from mortgage-related activity. A mortgage REIT makes loans to developers and owners of properties and invests primarily in mortgages and similar real estate interests, and includes companies or trusts that are primarily engaged in the purchasing or servicing of commercial or residential mortgage loans or mortgage-related securities, which may include mortgage-backed securities issued by private issuers and those issued or guaranteed by U.S. Government agencies, instrumentalities or sponsored entities. The Index may include small-capitalization and mid-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 the real estate sector.

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.

Risk of Investing in Mortgage REITs. Mortgage REITs are exposed to the risks specific to the real estate market as well as the risks that relate specifically to the way in which mortgage REITs are organized and operated. Mortgage REITs receive principal and interest payments from the owners of the mortgaged properties. Accordingly, mortgage REITs are subject to the credit risk of the borrowers to whom they extend credit. Credit risk refers to the possibility that the borrower will be unable and/or unwilling to make timely interest payments and/or repay the principal on the loan to a mortgage REIT when due. To the extent that a mortgage REIT invests in mortgage-backed securities offered by private issuers, such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers, the mortgage REIT may be subject to additional risks. Timely payment of interest and principal of non-governmental issuers are supported by various forms of private insurance or guarantees, including individual loan, title, pool and hazard insurance purchased by the issuer. There can be no assurance that the private insurers can meet their obligations under such policies. Unexpected high rates of default on the mortgages held by a mortgage pool may adversely affect the value of a mortgage-backed security and could result in losses to a mortgage REIT. The risk of such defaults is generally higher in the case of mortgage pools that include subprime mortgages. To the extent that a mortgage REIT’s portfolio is exposed to lower-rated, unsecured or subordinated instruments, the risk of loss may increase, which may have a negative impact on the Fund.

Mortgage REITs are subject to significant interest rate risk. Interest rate risk refers to fluctuations in the value of a mortgage REIT’s investment in fixed rate obligations resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the value of a mortgage REIT’s investment in fixed rate obligations goes down. When the general level of interest rates goes down, the value of a mortgage REIT’s investment in fixed rate obligations goes up.

Mortgage REITs typically use leverage and many are highly leveraged, which exposes them to leverage risk. Leverage risk refers to the risk that leverage created from borrowing may impair a mortgage REIT’s liquidity, cause it to liquidate positions at an unfavorable time and increase the volatility of the values of securities issued by the mortgage REIT.

Mortgage REITs are subject to prepayment risk, which is the risk that borrowers may prepay their mortgage loans at faster than expected rates. Prepayment rates generally increase when interest rates fall and decrease when interest rates rise. These faster than expected payments may adversely affect a mortgage REIT’s profitability because the mortgage REIT may be forced to replace investments that have been redeemed or repaid early with other investments having a lower yield. Additionally, rising interest rates rise may cause the duration of a mortgage REIT’s investments to be longer than anticipated and increase such investments’ interest rate sensitivity.

REITs are subject to special U.S. federal tax requirements. A REIT’s failure to comply with these requirements may negatively affect its performance.

Mortgage REITs may be dependent upon management skills and may have limited financial resources. Mortgage REITs are generally not diversified and may be subject to heavy cash flow dependency, default by borrowers and self-liquidation. In addition, transactions between mortgage REITs and their affiliates may be subject to conflicts of interest which may adversely affect a mortgage REIT’s shareholders.

Risk of Investing in the Real Estate Sector. The Fund invests in companies that invest in real estate, such as mortgage REITs, which subjects the Fund to the risks of owning real estate directly. Adverse economic, business or political developments affecting real estate could have a major effect on the value of the Fund’s investments.

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 risk 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. 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. 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 prices (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.

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 the real estate sector. By concentrating its assets in the real estate sector, the Fund is subject to the risk that economic, political or other conditions that have a negative effect on that sector will negatively impact the Fund to a greater extent than if the Fund’s assets were invested in a wider variety of sectors or industries.

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 0.40% 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.
