GLOBAL LISTED PRIVATE EQUITY ETF

GLOBAL LISTED PRIVATE EQUITY ETF

Investment Objective

ProShares Global Listed Private Equity ETF (the “Fund”) seeks investment results, before fees and expenses, that track the performance of the LPX Direct Listed Private Equity Index (the “Index”).

Fees and Expenses of the Fund

The table below describes the fees and expenses that you may pay if you buy or hold shares of the Fund.

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

Annual Fund Operating Expenses	GLOBAL LISTED PRIVATE EQUITY ETF ProShares Global Listed Private Equity ETF
Investment Advisory Fees	0.50%
Other Expenses	1.37%
Acquired Fund Fees and Expenses	2.15%	[1]
Total Annual Fund Operating Expenses Before Fee Waivers and Expense Reimbursements	4.02%
Fee Waiver/Reimbursement	(1.27%)	[2]
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	2.75%

Example:

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other 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 each period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, except that the fee waiver/expense reimbursement is assumed only to pertain to the first year. Although your actual costs may be higher or lower, based on these assumptions your approximate costs would be:

Expense Example	1 Year	3 Years	5 Years	10 Years
GLOBAL LISTED PRIVATE EQUITY ETF | ProShares Global Listed Private Equity ETF | USD ($)	278	1,108	1,955	4,145

The Fund pays transaction costs associated with the purchase and sale of securities. In addition, investors may pay brokerage commissions on their purchases and sales of the Fund’s shares. These costs are not reflected in the table or the example above.

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 the Fund’s shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the example above, affect the Fund’s performance. During the most recent fiscal year, the Fund’s annual portfolio turnover rate was 34% of the average value of its entire portfolio.

Principal Investment Strategies

The Index, published by LPX AG (“LPX”), consists of up to 30 qualifying listed private equity companies. A listed private equity company is an eligible candidate for the Index if its direct private equity investments, as well as cash and cash equivalent positions and post-initial public offering listed investments, represent more than 80% of the total assets of the company. LPX considers direct private equity investments to be direct investments noted on the balance sheet of the listed private equity company in the equity, mezzanine or debt facility of an underlying private company or investments in limited partnerships managed by the management portion of the listed private equity company. Each candidate for the Index will have a majority of its assets invested in or exposed to private companies or have a stated intention to have a majority of its assets invested in or exposed to private companies.

The Index applies a liquidity screen to qualifying companies and then includes up to 30 of the remaining companies based on, among other things, greater relative trading volume (i.e., trading volume relative to the market capitalization of the company). The Index historically has included securities of all market capitalizations, from micro- to large-cap. As of May 31, 2017, the Index included companies with capitalizations between approximately $531.9 million and $11.2 billion. The average capitalization of the companies comprising the Index was approximately $2.5 billion. The Index is reconstituted quarterly and is published under the Bloomberg ticker symbol “LPXDITU”.

The Fund invests in securities that ProShare Advisors believes, in combination, should track the performance of the Index. Under normal circumstances, the Fund will invest at least 80% of its total assets in component securities (i.e., securities of the Index and comparable securities that have economic characteristics that are substantially identical to the economic characteristics of the securities of the Index). The securities that the Fund will principally invest in are set forth below

• Equity Securities — The Fund invests in common stock issued by U.S. and foreign public companies, including in large part business development companies (“BDCs”) for U.S. domiciled companies. BDCs are specialized investment vehicles that provide financing to small- and middle-market companies and offer managerial expertise, as needed, to assist those companies.

ProShare Advisors follows a passive approach to investing that is designed to track the performance of the Index. The Fund attempts to track the performance of the Index by investing all, or substantially all, of its assets in securities that make up the Index. The Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index, with the intent of obtaining exposure with aggregate characteristics similar to those of the Index. ProShare Advisors does not invest the assets of the Fund in securities based on ProShare Advisors’ view of the investment merit of a particular security or company, nor does it conduct conventional investment research or analysis or forecast market movement or trends, in managing the assets of the Fund. The Fund seeks to remain fully invested at all times in securities that, in combination, provide exposure to the Index without regard to market conditions, trends or direction.

The Fund will concentrate its investments in a particular industry or group of industries, country or region to approximately the same extent as the Index is so concentrated. As of the close of business on May 31, 2017, the Index was concentrated in the financials industry group and in Europe.

Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the back of the Fund’s Full Prospectus for additional details.

Principal Risks

You could lose money by investing in the Fund.

• Correlation Risk — A number of factors may affect the Fund’s ability to achieve a high degree of correlation with the Index, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The factors that may adversely affect the Fund’s correlation with the Index, include fees, expenses, transaction costs, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities in which the Fund invests. The Fund may not have investment exposure to all securities in the Index, or its weighting of investment exposure to securities may be different from that of the Index. In addition, the Fund may invest in securities not included in the Index. The Fund may take or refrain from taking positions in order to improve tax efficiency, or comply with regulatory restrictions, either of which may negatively affect the Fund’s correlation with the Index. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or underexposed to the Index and may be impacted by Index reconstitutions and Index rebalancing events. Additionally, the Fund’s underlying investments may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the level of the Index. Furthermore, the Fund’s currency holdings may be valued at a different time than the level of the Index. Any of these factors could decrease correlation between the performance of the Fund and the Index and may hinder the Fund’s ability to meet its investment objective.

• Early Close/Late Close/Trading Halt Risk — An exchange or market may close early, close late or issue trading halts on specific securities, or the ability to buy or sell certain securities may be restricted, which may result in the Fund being unable to buy or sell certain securities. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

• Equity and Market Risk — The equity markets are volatile, and the value of securities correlated with the equity markets may fluctuate dramatically from day-to-day. Equity markets are subject to corporate, political, regulatory, market and economic developments, as well as developments that impact specific economic sectors, industries or segments of the market. Further, stocks in the Index may underperform other equity investments. Volatility in the markets and/or market developments may cause the value of an investment in the Fund to decrease.

• European Investments Risk — The Fund is exposed, to a greater extent than more geographically diversified funds, to risks associated with investments in Europe. Many countries included in the Index are members of the European Union (the “EU”) and all European countries may be significantly affected by EU policies and may be highly dependent on the economies of their fellow members. The European financial markets have experienced significant volatility and several European countries have been adversely affected by unemployment, budget deficits and economic downturns. In addition, several European countries have experienced credit rating downgrades, rising government debt levels and, for certain European countries (including Spain, Portugal, Ireland and Italy), weaknesses in sovereign debt. These events, along with decreasing imports or exports, changes in governmental or EU regulations on trade, the default or threat of default by a European country on its sovereign debt and/or an economic recession in a European country may have a significant adverse effect on the affected European country, issuers in the affected European country, the economies of other European countries, or their trading partners. Such events, or even the threat of these events, may cause the value of securities issued by issuers in such European countries to fall, in some cases drastically. These events may also cause further volatility in the European financial markets. To the extent that the Fund’s assets are exposed to investments from issuers in European countries or denominated in euro, their trading partners, or other European countries, these events may negatively impact the performance of the Fund.

• Financials Industry Risk — The Fund is subject to risks faced by companies in the financials economic sector to the same extent as the Index is so concentrated, including: extensive governmental regulation and/or nationalization that affects the scope of their activities, the prices they can charge and the amount of capital they must maintain; adverse effects from increases in interest rates; effects on profitability by loan losses, which usually increase in economic downturns; the severe competition to which banks, insurance, and financial services companies may be subject; and increased inter-industry consolidation and competition in the financials sector. The impact of more stringent capital requirements, recent or future regulation on any individual financial company or recent or future regulation on the financials economic sector as a whole cannot be predicted.

• Foreign Currency Risk — Certain of the Fund’s investments may be linked to or denominated in foreign currencies. Investments linked to or denominated in foreign currencies are exposed to additional risk factors versus those investments denominated in U.S. dollars or linked to U.S. investments. The value of an investment denominated in a foreign currency could change significantly as foreign currencies strengthen or weaken relative to the U.S. dollar. Devaluations of a currency by a government or banking authority may also have significant impact on the value of any investments denominated in that currency. Risks related to foreign currencies also include those related to economic or political developments, market inefficiencies or a higher risk that essential investment information may be incomplete, unavailable, or inaccurate. A U.S. dollar investment in an investment denominated in a foreign currency, like certain of the investments included in the Index, is subject to foreign currency risk. Foreign currency losses could offset or exceed any potential gains, or add to losses, in the related investments. Currency markets are also generally not as regulated as securities markets. In addition, in order to transact in foreign investments, the Fund may exchange and hold foreign currencies. Regulatory fees or higher custody fees may be imposed on foreign currency holdings. In certain “restricted market” countries (which limit the ability of non-nationals to transact in those countries’ currencies), the Fund will be limited in its ability to use multiple dealers to obtain exchange rates. This may result in potentially higher costs for the Fund, and increased correlation risk. Further the limitation on dealers may cause delays in execution, which may also increase correlation risk.

• Foreign Investments/Emerging Market Risk — Investing in securities of foreign issuers may provide the Fund with increased risk. Various factors related to foreign investments may negatively impact the Fund’s and Index’s performance, such as: i) fluctuations in the value of the applicable foreign currency; ii) differences in securities settlement practices; iii) uncertainty associated with evidence of ownership of investments in countries that lack centralized custodial services; iv) possible regulation of, or other limitations on, investments by U.S. investors in foreign investments; v) potentially higher brokerage commissions; vi) the possibility that a foreign government may withhold portions of interest and dividends at the source; vii) taxation of income earned in foreign countries or other foreign taxes imposed; viii) foreign exchange controls, which may include suspension of the ability to transfer currency from a foreign country; ix) less publicly available information about foreign issuers; x) changes in the denomination currency of a foreign investment; and xi) less certain legal systems in which the Fund might encounter difficulties or be unable to pursue legal remedies. Foreign investments also may be more susceptible to political, social, economic and regional factors than might be the case with U.S. securities. In addition, markets for foreign investments are usually less liquid, more volatile and significantly smaller than markets for U.S. securities, which may affect, among other things, the Fund’s ability to purchase or sell foreign investments at appropriate times. Because of differences in settlement times and/or foreign market holidays, transactions in a foreign market may take place one or more days after the necessary exposure to these investments is determined. Until the transactions are effected, the Fund is exposed to increased foreign currency risk and market risk and, ultimately, increased correlation risk.
  
  Because the Fund’s foreign investments will include issuers domiciled in developing or “emerging market” countries, all the aforementioned factors are heightened and foreign investments risk is higher. Economic, business, political, or social instability may adversely affect the value of emerging market securities more acutely than securities tied to developed foreign countries. Furthermore, any of these developments may result in a decline in the value of a country’s currency. Emerging markets are riskier than more developed markets because they may develop unevenly or may never fully develop. Investments in emerging markets are considered speculative.

• Geographic Concentration Risk — Because the Fund focuses its investments in particular foreign countries or geographic regions, it may be more volatile than a more geographically diversified fund. The performance of the Fund will be affected by the political, social and economic conditions in those foreign countries and geographic regions and subject to the related risks.

• Index Performance Risk — There is no guarantee or assurance that the methodology used to create the Index will result in the Fund achieving high, or even positive, returns. The Index may underperform, and the Fund could lose value, while other indices or measures of market performance increase in value.

• Liquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the securities in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of ProShare Advisors. Markets for the securities in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, natural disasters, new legislation, or regulatory changes inside or outside of the U.S. For example, regulation limiting the ability of certain financial institutions to invest in certain securities would likely reduce the liquidity of those securities. These situations may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index.

• Market Price Variance Risk — Fund shares are listed for trading on the Bats BZX Exchange, Inc. and can be bought and sold in the secondary market at market prices. The market prices of shares will fluctuate in response to changes in the value of the Fund’s holdings, supply and demand for shares and other market factors. In addition, the securities held by the Fund may be traded in markets that close at a different time than the Exchange. Because the Fund and the Index generally value such securities as of their local market closing time, the daily net asset value (“NAV”) and Index performance will vary from the market performance of the Fund as of the Exchange close (typically at 4:00 p.m., Eastern Time). Furthermore, liquidity in such securities may be reduced after the applicable closing times. This may cause wider spreads and larger premium and discounts than would otherwise be the case if each market was open until the close of trading on the Exchange. ProShare Advisors cannot predict whether shares will trade above, below or at a price equal to the value of the Fund’s holdings. Given the fact that shares can be created and redeemed in Creation Units, as defined below, ProShare Advisors believes that large discounts or premiums to the value of the Fund’s holdings should not be sustained. The Fund’s investment results are measured based upon the daily NAV of the Fund. Investors purchasing and selling shares in the secondary market may not experience investment results consistent with those experienced by Authorized Participants creating and redeeming directly with the Fund. To the extent that exchange specialists, market makers, Authorized Participants, or other participants are unavailable or unable to trade the Fund’s shares and/or create or redeem Creation Units, trading spreads and the resulting premium or discount on the Fund’s shares may widen and the Fund’s shares may possibly be subject to trading halts and/or delisting.

• Non-Diversification Risk — The Fund is classified as “non-diversified” under the Investment Company Act of 1940 (“1940 Act”), and has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers susceptible to a single economic, political or regulatory event. This may increase the Fund’s volatility and cause performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. This risk may be particularly acute if the Index is comprised of a small number of securities. Notwithstanding the Fund’s status as a “non-diversified” investment company under the 1940 Act, the Fund intends to qualify as a “regulated investment company” (“RIC”) accorded special tax treatment under the Internal Revenue Code, which imposes its own diversification requirements that are less restrictive than the requirements applicable to “diversified” investment companies under the 1940 Act.

• Portfolio Turnover Risk — In seeking to meet its investment objective, the Fund may incur high portfolio turnover to manage the Fund’s investment exposure. Additionally, active market trading of the Fund’s shares may cause more frequent creation or redemption activities that could, in certain circumstances, increase the number of portfolio transactions. High levels of transactions increase brokerage and other transaction costs and may result in increased taxable capital gains.

• Risks Relating to Investing in Business Development Companies (BDCs) — BDCs are special investment vehicles designed to facilitate capital formation for small and middle-market companies. BDCs are closed-end investment companies subject to the 1940 Act; however, BDCs are exempt from many of the regulatory constraints imposed by the 1940 Act. A BDC is a domestic company that (1) operates for the purpose of making investments in certain securities and, with limited exceptions, makes available “significant managerial assistance” with respect to the issuers of such securities, and (2) has elected business development company status. As a general matter, a BDC must maintain at least 70% of its investments in certain types of eligible portfolio companies that do not have securities listed on a national securities exchange or that have less than $250 million in aggregate market value. The Fund is subject to risks faced by BDCs to the same extent as the Index is so concentrated, including: increasing competition for limited BDC investment opportunities; potential uncertainty as to the value of a BDC’s private investments; risks associated with leverage; and reliance on a BDC’s managerial acumen.

• Risks Relating to Investing in Listed Private Equity Companies — The Fund is subject to risks faced by companies in the private equity sector to the same extent as the Index is so concentrated, in particular the skill of such companies in selecting underlying investments. There are certain risks inherent in investing in listed private equity companies, which encompass business development companies (BDCs) and other financial institutions or vehicles whose principal business is to invest in and provide mezzanine financing to privately held companies. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. Private equity securities additionally carry other risks including those related to unclear ownership, market access constraints and market opaqueness. In addition, at times, a private equity company may hold a significant portion of its assets in cash or cash equivalents (e.g., after divesting itself of its interests in a portfolio company upon the portfolio company’s IPO, merger or recapitalization). This may result in lower returns than if the private equity company had invested such cash or cash equivalents in successful portfolio companies.

• Risks Relating to Restrictions on Investment Company Investments — A significant portion of the Index is composed of BDCs or other investment companies. The Fund may not acquire greater than three percent (3%) of the total outstanding shares of such companies. As a result, the Fund’s ability to purchase certain of the securities in the Index in the proportions represented in the Index could be inhibited. In these circumstances, the Fund may be required to use sampling techniques, which could increase “Correlation Risk”, as described above.

• Small- and Mid-Cap Company Investment Risk — The Index and by extension, the Fund are exposed to stocks of small- and mid-cap companies. The risk of equity investing may be particularly acute for securities of issuers with smaller market capitalizations. Small- and mid-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies. Small- and mid-cap companies may have limited product lines or resources, may be dependent upon a particular market niche and may have greater fluctuations in price than the stocks of larger companies. Further, stocks of small- and mid-sized companies could be more difficult to liquidate during market downturns compared to larger, more widely traded companies. In addition, small- and mid-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on small- and mid-cap security prices.

• Tax Risk — In order to qualify for the special tax treatment accorded a RIC and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategies will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund can make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the Statement of Additional Information for more information.

• Valuation Risk — In certain circumstances, portfolio securities may be valued using techniques other than market quotations. The value established for a portfolio security may be different from what would be produced through the use of another methodology or if it had been priced using market quotations. Portfolio securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio security for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio security is sold at a discount to its established value.

Average annual total returns are shown on a before- and after-tax basis for the Fund. After-tax returns are calculated using the historical highest individual federal marginal income tax rates 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 shown are not relevant to investors who hold shares through tax-deferred arrangements, such as a retirement account. After-tax returns may exceed the return before taxes due to a tax benefit from realizing a capital loss on a sale of shares.

[1] “Acquired Fund Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies (such as business development companies and/or exchange-traded funds). They are not direct costs paid by Fund shareholders and are not used to calculate the Fund’s net asset value (“NAV”). “Acquired Fund Fees and Expenses” are not directly borne by the Fund and are not reflected in the Fund’s Financial Statements in the annual report. Therefore, the amounts listed in “Total Annual Fund Operating Expenses Before Fee Waivers and Expense Reimbursements” will differ from those presented in the Fund’s Financial Highlights in the back of the Full Prospectus.

[2] ProShare Advisors LLC (“ProShare Advisors”) has contractually agreed to waive Investment Advisory and Management Services Fees and to reimburse Other Expenses to the extent Total Annual Fund Operating Expenses Before Fee Waivers and Expense Reimbursements (excluding Acquired Fund Fees and Expenses), as a percentage of average daily net assets, exceed 0.60% through September 30, 2018. After such date, the expense limitation may be terminated or revised by ProShare Advisors. Amounts waived or reimbursed in a particular contractual period may be recouped by ProShare Advisors within five years of the end of that contractual period, however, such recoupment will be limited to the lesser of any expense limitation in place at the time of recoupment or the expense limitation in place at the time of waiver or reimbursement.

[1] Reflects no deduction for fees, expenses or taxes. Adjusted to reflect the reinvestment of dividends paid by companies in the Index. Since Inception returns are calculated from the date the Fund commenced operations, not the date of inception of the Index.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Index, published by LPX AG (“LPX”), consists of up to 30 qualifying listed private equity companies. A listed private equity company is an eligible candidate for the Index if its direct private equity investments, as well as cash and cash equivalent positions and post-initial public offering listed investments, represent more than 80% of the total assets of the company. LPX considers direct private equity investments to be direct investments noted on the balance sheet of the listed private equity company in the equity, mezzanine or debt facility of an underlying private company or investments in limited partnerships managed by the management portion of the listed private equity company. Each candidate for the Index will have a majority of its assets invested in or exposed to private companies or have a stated intention to have a majority of its assets invested in or exposed to private companies. The Index applies a liquidity screen to qualifying companies and then includes up to 30 of the remaining companies based on, among other things, greater relative trading volume (i.e., trading volume relative to the market capitalization of the company). The Index historically has included securities of all market capitalizations, from micro- to large-cap. As of May 31, 2017, the Index included companies with capitalizations between approximately $531.9 million and $11.2 billion. The average capitalization of the companies comprising the Index was approximately $2.5 billion. The Index is reconstituted quarterly and is published under the Bloomberg ticker symbol “LPXDITU”. The Fund invests in securities that ProShare Advisors believes, in combination, should track the performance of the Index. Under normal circumstances, the Fund will invest at least 80% of its total assets in component securities (i.e., securities of the Index and comparable securities that have economic characteristics that are substantially identical to the economic characteristics of the securities of the Index). The securities that the Fund will principally invest in are set forth below Equity Securities — The Fund invests in common stock issued by U.S. and foreign public companies, including in large part business development companies (“BDCs”) for U.S. domiciled companies. BDCs are specialized investment vehicles that provide financing to small- and middle-market companies and offer managerial expertise, as needed, to assist those companies. ProShare Advisors follows a passive approach to investing that is designed to track the performance of the Index. The Fund attempts to track the performance of the Index by investing all, or substantially all, of its assets in securities that make up the Index. The Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index, with the intent of obtaining exposure with aggregate characteristics similar to those of the Index. ProShare Advisors does not invest the assets of the Fund in securities based on ProShare Advisors’ view of the investment merit of a particular security or company, nor does it conduct conventional investment research or analysis or forecast market movement or trends, in managing the assets of the Fund. The Fund seeks to remain fully invested at all times in securities that, in combination, provide exposure to the Index without regard to market conditions, trends or direction. The Fund will concentrate its investments in a particular industry or group of industries, country or region to approximately the same extent as the Index is so concentrated. As of the close of business on May 31, 2017, the Index was concentrated in the financials industry group and in Europe. Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the back of the Fund’s Full Prospectus for additional details.

Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	You could lose money by investing in the Fund. Correlation Risk — A number of factors may affect the Fund’s ability to achieve a high degree of correlation with the Index, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The factors that may adversely affect the Fund’s correlation with the Index, include fees, expenses, transaction costs, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities in which the Fund invests. The Fund may not have investment exposure to all securities in the Index, or its weighting of investment exposure to securities may be different from that of the Index. In addition, the Fund may invest in securities not included in the Index. The Fund may take or refrain from taking positions in order to improve tax efficiency, or comply with regulatory restrictions, either of which may negatively affect the Fund’s correlation with the Index. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or underexposed to the Index and may be impacted by Index reconstitutions and Index rebalancing events. Additionally, the Fund’s underlying investments may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the level of the Index. Furthermore, the Fund’s currency holdings may be valued at a different time than the level of the Index. Any of these factors could decrease correlation between the performance of the Fund and the Index and may hinder the Fund’s ability to meet its investment objective. Early Close/Late Close/Trading Halt Risk — An exchange or market may close early, close late or issue trading halts on specific securities, or the ability to buy or sell certain securities may be restricted, which may result in the Fund being unable to buy or sell certain securities. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Equity and Market Risk — The equity markets are volatile, and the value of securities correlated with the equity markets may fluctuate dramatically from day-to-day. Equity markets are subject to corporate, political, regulatory, market and economic developments, as well as developments that impact specific economic sectors, industries or segments of the market. Further, stocks in the Index may underperform other equity investments. Volatility in the markets and/or market developments may cause the value of an investment in the Fund to decrease. European Investments Risk — The Fund is exposed, to a greater extent than more geographically diversified funds, to risks associated with investments in Europe. Many countries included in the Index are members of the European Union (the “EU”) and all European countries may be significantly affected by EU policies and may be highly dependent on the economies of their fellow members. The European financial markets have experienced significant volatility and several European countries have been adversely affected by unemployment, budget deficits and economic downturns. In addition, several European countries have experienced credit rating downgrades, rising government debt levels and, for certain European countries (including Spain, Portugal, Ireland and Italy), weaknesses in sovereign debt. These events, along with decreasing imports or exports, changes in governmental or EU regulations on trade, the default or threat of default by a European country on its sovereign debt and/or an economic recession in a European country may have a significant adverse effect on the affected European country, issuers in the affected European country, the economies of other European countries, or their trading partners. Such events, or even the threat of these events, may cause the value of securities issued by issuers in such European countries to fall, in some cases drastically. These events may also cause further volatility in the European financial markets. To the extent that the Fund’s assets are exposed to investments from issuers in European countries or denominated in euro, their trading partners, or other European countries, these events may negatively impact the performance of the Fund. Financials Industry Risk — The Fund is subject to risks faced by companies in the financials economic sector to the same extent as the Index is so concentrated, including: extensive governmental regulation and/or nationalization that affects the scope of their activities, the prices they can charge and the amount of capital they must maintain; adverse effects from increases in interest rates; effects on profitability by loan losses, which usually increase in economic downturns; the severe competition to which banks, insurance, and financial services companies may be subject; and increased inter-industry consolidation and competition in the financials sector. The impact of more stringent capital requirements, recent or future regulation on any individual financial company or recent or future regulation on the financials economic sector as a whole cannot be predicted. Foreign Currency Risk — Certain of the Fund’s investments may be linked to or denominated in foreign currencies. Investments linked to or denominated in foreign currencies are exposed to additional risk factors versus those investments denominated in U.S. dollars or linked to U.S. investments. The value of an investment denominated in a foreign currency could change significantly as foreign currencies strengthen or weaken relative to the U.S. dollar. Devaluations of a currency by a government or banking authority may also have significant impact on the value of any investments denominated in that currency. Risks related to foreign currencies also include those related to economic or political developments, market inefficiencies or a higher risk that essential investment information may be incomplete, unavailable, or inaccurate. A U.S. dollar investment in an investment denominated in a foreign currency, like certain of the investments included in the Index, is subject to foreign currency risk. Foreign currency losses could offset or exceed any potential gains, or add to losses, in the related investments. Currency markets are also generally not as regulated as securities markets. In addition, in order to transact in foreign investments, the Fund may exchange and hold foreign currencies. Regulatory fees or higher custody fees may be imposed on foreign currency holdings. In certain “restricted market” countries (which limit the ability of non-nationals to transact in those countries’ currencies), the Fund will be limited in its ability to use multiple dealers to obtain exchange rates. This may result in potentially higher costs for the Fund, and increased correlation risk. Further the limitation on dealers may cause delays in execution, which may also increase correlation risk. Foreign Investments/Emerging Market Risk — Investing in securities of foreign issuers may provide the Fund with increased risk. Various factors related to foreign investments may negatively impact the Fund’s and Index’s performance, such as: i) fluctuations in the value of the applicable foreign currency; ii) differences in securities settlement practices; iii) uncertainty associated with evidence of ownership of investments in countries that lack centralized custodial services; iv) possible regulation of, or other limitations on, investments by U.S. investors in foreign investments; v) potentially higher brokerage commissions; vi) the possibility that a foreign government may withhold portions of interest and dividends at the source; vii) taxation of income earned in foreign countries or other foreign taxes imposed; viii) foreign exchange controls, which may include suspension of the ability to transfer currency from a foreign country; ix) less publicly available information about foreign issuers; x) changes in the denomination currency of a foreign investment; and xi) less certain legal systems in which the Fund might encounter difficulties or be unable to pursue legal remedies. Foreign investments also may be more susceptible to political, social, economic and regional factors than might be the case with U.S. securities. In addition, markets for foreign investments are usually less liquid, more volatile and significantly smaller than markets for U.S. securities, which may affect, among other things, the Fund’s ability to purchase or sell foreign investments at appropriate times. Because of differences in settlement times and/or foreign market holidays, transactions in a foreign market may take place one or more days after the necessary exposure to these investments is determined. Until the transactions are effected, the Fund is exposed to increased foreign currency risk and market risk and, ultimately, increased correlation risk. Because the Fund’s foreign investments will include issuers domiciled in developing or “emerging market” countries, all the aforementioned factors are heightened and foreign investments risk is higher. Economic, business, political, or social instability may adversely affect the value of emerging market securities more acutely than securities tied to developed foreign countries. Furthermore, any of these developments may result in a decline in the value of a country’s currency. Emerging markets are riskier than more developed markets because they may develop unevenly or may never fully develop. Investments in emerging markets are considered speculative. Geographic Concentration Risk — Because the Fund focuses its investments in particular foreign countries or geographic regions, it may be more volatile than a more geographically diversified fund. The performance of the Fund will be affected by the political, social and economic conditions in those foreign countries and geographic regions and subject to the related risks. Index Performance Risk — There is no guarantee or assurance that the methodology used to create the Index will result in the Fund achieving high, or even positive, returns. The Index may underperform, and the Fund could lose value, while other indices or measures of market performance increase in value. Liquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the securities in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of ProShare Advisors. Markets for the securities in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, natural disasters, new legislation, or regulatory changes inside or outside of the U.S. For example, regulation limiting the ability of certain financial institutions to invest in certain securities would likely reduce the liquidity of those securities. These situations may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index. Market Price Variance Risk — Fund shares are listed for trading on the Bats BZX Exchange, Inc. and can be bought and sold in the secondary market at market prices. The market prices of shares will fluctuate in response to changes in the value of the Fund’s holdings, supply and demand for shares and other market factors. In addition, the securities held by the Fund may be traded in markets that close at a different time than the Exchange. Because the Fund and the Index generally value such securities as of their local market closing time, the daily net asset value (“NAV”) and Index performance will vary from the market performance of the Fund as of the Exchange close (typically at 4:00 p.m., Eastern Time). Furthermore, liquidity in such securities may be reduced after the applicable closing times. This may cause wider spreads and larger premium and discounts than would otherwise be the case if each market was open until the close of trading on the Exchange. ProShare Advisors cannot predict whether shares will trade above, below or at a price equal to the value of the Fund’s holdings. Given the fact that shares can be created and redeemed in Creation Units, as defined below, ProShare Advisors believes that large discounts or premiums to the value of the Fund’s holdings should not be sustained. The Fund’s investment results are measured based upon the daily NAV of the Fund. Investors purchasing and selling shares in the secondary market may not experience investment results consistent with those experienced by Authorized Participants creating and redeeming directly with the Fund. To the extent that exchange specialists, market makers, Authorized Participants, or other participants are unavailable or unable to trade the Fund’s shares and/or create or redeem Creation Units, trading spreads and the resulting premium or discount on the Fund’s shares may widen and the Fund’s shares may possibly be subject to trading halts and/or delisting. Non-Diversification Risk — The Fund is classified as “non-diversified” under the Investment Company Act of 1940 (“1940 Act”), and has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers susceptible to a single economic, political or regulatory event. This may increase the Fund’s volatility and cause performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. This risk may be particularly acute if the Index is comprised of a small number of securities. Notwithstanding the Fund’s status as a “non-diversified” investment company under the 1940 Act, the Fund intends to qualify as a “regulated investment company” (“RIC”) accorded special tax treatment under the Internal Revenue Code, which imposes its own diversification requirements that are less restrictive than the requirements applicable to “diversified” investment companies under the 1940 Act. Portfolio Turnover Risk — In seeking to meet its investment objective, the Fund may incur high portfolio turnover to manage the Fund’s investment exposure. Additionally, active market trading of the Fund’s shares may cause more frequent creation or redemption activities that could, in certain circumstances, increase the number of portfolio transactions. High levels of transactions increase brokerage and other transaction costs and may result in increased taxable capital gains. Risks Relating to Investing in Business Development Companies (BDCs) — BDCs are special investment vehicles designed to facilitate capital formation for small and middle-market companies. BDCs are closed-end investment companies subject to the 1940 Act; however, BDCs are exempt from many of the regulatory constraints imposed by the 1940 Act. A BDC is a domestic company that (1) operates for the purpose of making investments in certain securities and, with limited exceptions, makes available “significant managerial assistance” with respect to the issuers of such securities, and (2) has elected business development company status. As a general matter, a BDC must maintain at least 70% of its investments in certain types of eligible portfolio companies that do not have securities listed on a national securities exchange or that have less than $250 million in aggregate market value. The Fund is subject to risks faced by BDCs to the same extent as the Index is so concentrated, including: increasing competition for limited BDC investment opportunities; potential uncertainty as to the value of a BDC’s private investments; risks associated with leverage; and reliance on a BDC’s managerial acumen. Risks Relating to Investing in Listed Private Equity Companies — The Fund is subject to risks faced by companies in the private equity sector to the same extent as the Index is so concentrated, in particular the skill of such companies in selecting underlying investments. There are certain risks inherent in investing in listed private equity companies, which encompass business development companies (BDCs) and other financial institutions or vehicles whose principal business is to invest in and provide mezzanine financing to privately held companies. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. Private equity securities additionally carry other risks including those related to unclear ownership, market access constraints and market opaqueness. In addition, at times, a private equity company may hold a significant portion of its assets in cash or cash equivalents (e.g., after divesting itself of its interests in a portfolio company upon the portfolio company’s IPO, merger or recapitalization). This may result in lower returns than if the private equity company had invested such cash or cash equivalents in successful portfolio companies. Risks Relating to Restrictions on Investment Company Investments — A significant portion of the Index is composed of BDCs or other investment companies. The Fund may not acquire greater than three percent (3%) of the total outstanding shares of such companies. As a result, the Fund’s ability to purchase certain of the securities in the Index in the proportions represented in the Index could be inhibited. In these circumstances, the Fund may be required to use sampling techniques, which could increase “Correlation Risk”, as described above. Small- and Mid-Cap Company Investment Risk — The Index and by extension, the Fund are exposed to stocks of small- and mid-cap companies. The risk of equity investing may be particularly acute for securities of issuers with smaller market capitalizations. Small- and mid-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies. Small- and mid-cap companies may have limited product lines or resources, may be dependent upon a particular market niche and may have greater fluctuations in price than the stocks of larger companies. Further, stocks of small- and mid-sized companies could be more difficult to liquidate during market downturns compared to larger, more widely traded companies. In addition, small- and mid-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on small- and mid-cap security prices. Tax Risk — In order to qualify for the special tax treatment accorded a RIC and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategies will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund can make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the Statement of Additional Information for more information. Valuation Risk — In certain circumstances, portfolio securities may be valued using techniques other than market quotations. The value established for a portfolio security may be different from what would be produced through the use of another methodology or if it had been priced using market quotations. Portfolio securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio security for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio security is sold at a discount to its established value. Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the back of the Fund’s Full Prospectus for additional details.

[1] “Acquired Fund Fees and Expenses” are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies (such as business development companies and/or exchange-traded funds). They are not direct costs paid by Fund shareholders and are not used to calculate the Fund’s net asset value (“NAV”). “Acquired Fund Fees and Expenses” are not directly borne by the Fund and are not reflected in the Fund’s Financial Statements in the annual report. Therefore, the amounts listed in “Total Annual Fund Operating Expenses Before Fee Waivers and Expense Reimbursements” will differ from those presented in the Fund’s Financial Highlights in the back of the Full Prospectus.

[2] ProShare Advisors LLC (“ProShare Advisors”) has contractually agreed to waive Investment Advisory and Management Services Fees and to reimburse Other Expenses to the extent Total Annual Fund Operating Expenses Before Fee Waivers and Expense Reimbursements (excluding Acquired Fund Fees and Expenses), as a percentage of average daily net assets, exceed 0.60% through September 30, 2018. After such date, the expense limitation may be terminated or revised by ProShare Advisors. Amounts waived or reimbursed in a particular contractual period may be recouped by ProShare Advisors within five years of the end of that contractual period, however, such recoupment will be limited to the lesser of any expense limitation in place at the time of recoupment or the expense limitation in place at the time of waiver or reimbursement.

[3] Reflects no deduction for fees, expenses or taxes. Adjusted to reflect the reinvestment of dividends paid by companies in the Index. Since Inception returns are calculated from the date the Fund commenced operations, not the date of inception of the Index.
