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 cost may be higher or lower, based on these assumptions your approximate costs would be:

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

The Fund will concentrate its investments in a particular industry or group of industries to approximately the same extent as the Index is so concentrated. As of the close of business on June 30, 2013, the Index was concentrated in the industrials industry group, which comprised approximately 77.36% of the market capitalization of the Index’s long exposure.

Risk Narrative [Text Block]

You could lose money by investing in the Fund.

High Yield Risk — Exposure to high yield (lower rated) debt instruments (also known as “junk bonds”) may involve greater levels of credit, prepayment, liquidity and valuation risk than for higher rated instruments. High yield debt instruments may be more sensitive to economic changes, political changes, or adverse developments specific to a company than other fixed income instruments. These securities are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and a potential lack of a secondary or public market for securities. High yield debt instruments are considered speculative with respect to the issuer’s continuing ability to make principal and interest payments and, therefore, such instruments generally involve greater risk of default or price changes than higher rated debt instruments. An economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce market liquidity (liquidity risk). Less active markets may diminish the Fund’s ability to obtain accurate market quotations when valuing the portfolio securities and thereby give rise to valuation risk. High yield debt instruments may also present risks based on payment expectations. For example, these instruments may contain redemption or call provisions. If an issuer exercises these provisions in a declining interest rate market, the Fund would have to replace the security with a lower yielding security, resulting in a decreased return for investors. If the issuer of a security is in default with respect to interest or principal payments, the issuer’s security could lose its entire value. Furthermore, the transaction costs associated with the purchase and sale of high yield debt instruments may vary greatly depending upon a number of factors and may adversely affect the Fund’s performance.

Hedging Risk — The Index seeks to mitigate the potential negative impact of rising Treasury interest rates on the performance of high yield bonds. The short positions in Treasury Securities are not intended to mitigate credit risk or other factors influencing the price of high yield bonds, which may have a greater impact than rising or falling interest rates. There is no guarantee that the short positions will completely eliminate the interest rate risk of the long high yield bond positions. While the Fund seeks to achieve an effective duration of zero, the hedge cannot fully account for changes in the shape of the Treasury interest rate (yield) curve. Because the duration hedge is reset on a monthly basis, interest rate risk can develop intra-month. The Fund could lose money if either or both the Fund’s long and short positions produce negative returns.

When interest rates fall, an unhedged investment in the same high yield bonds will outperform the Fund. Performance of the Fund could be particularly poor in risk-averse, flight-to-quality environments when it is common for high yield bonds to decline in value and for interest rates to fall. Furthermore, when interest rates remain unchanged, an investment in the Fund will underperform a long-only investment in the same high yield bonds.

The Index may also contain a significant allocation to callable high yield bonds, which are subject to call/prepayment risk (see “Debt Instrument Risk” below); callable bonds may have lower sensitivity to interest rate declines than non-callable bonds or Treasury Securities. In certain falling interest rate environments, this could result in disproportionately larger losses in the short Treasury positions relative to the gains in the long high yield bond positions attributable to falling interest rates.

Risks Associated with the Use of Derivatives — The Fund obtains investment exposure through derivatives, which may be considered aggressive. Investing in derivatives may expose the Fund to greater risks than investing directly in the reference asset(s) underlying those derivatives, such as liquidity risk and increased correlation risk (each as discussed below). When the Fund uses derivatives, there may be imperfect correlation between the value of the reference asset(s) and the derivative, which may prevent the Fund from achieving its investment objective. Any costs associated with using derivatives may also have the effect of lowering the Fund’s return.

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. This may be due, in many cases, to the impact of a limited trading market in the component Index bonds on the calculation of the Index. Other factors that may adversely affect the Fund’s correlation with the Index include fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments 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 or in financial instruments. 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. 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.

Debt Instrument Risk — The Fund will invest in, or seek exposure to, debt instruments. Debt instruments may have varying levels of sensitivity to changes in interest rates, issuer credit risk and other factors. In addition, changes in the credit quality of the issuer of a debt instrument can also affect the price of a debt instrument, as can an issuer’s default on its payment obligations. Many types of debt instruments are subject to prepayment risk, which is the risk that the issuer of the security will repay principal (in part or in whole) prior to the maturity date. Debt instruments allowing prepayment may offer less potential for gains during a period of declining interest rates, as the Fund may be required to reinvest the proceeds at lower interest rates. These factors may cause the value of an investment in the Fund to change.

Credit Risk — Due to its investments in high yield bonds, the Fund will be subject to the risk that an issuer of a high yield bond is unwilling or unable to make timely payments to meet its contractual obligations. At times when credit risk increases, the price of the high yield bonds that comprise the Index (and therefore the value of the Fund) will typically decrease. Conversely, when credit risk of the bonds decreases, the level of the Index (and the value of the Fund) will typically increase. In using sampling techniques, the Fund may be overexposed to certain securities that would adversely affect the Fund upon the markets’ perceived view of increased credit risk or upon a downgrade or default of such securities. The hedging methodology of the Index does not seek to mitigate credit risk.

Interest Rate Risk — Interest rate risk is the risk that debt securities or related financial instruments may fluctuate in value due to changes in interest rates. Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and increase in value when interest rates decline. The value of securities with longer maturities typically fluctuates more in response to interest rate changes than securities with shorter maturities. The Index (and therefore the Fund) seeks to mitigate this risk by taking short positions in Treasury Securities; such short positions should increase in value in rising interest rate environments and should decrease in value in falling interest rate environments, thereby mitigating potential gains and losses in the high yield bond positions of the Fund arising from changing Treasury interest rates. When interest rates fall, an unhedged investment in the same high yield bonds will outperform the Fund. Because the duration hedge is reset on a monthly basis, interest rate risk can develop intra-month. Furthermore, while the Index is designed to hedge the interest rate exposure of the long high yield bond positions, it is possible that a degree of exposure may remain even at the time of rebalance.

Restricted Securities Risk — Privately issued securities are restricted securities that are not publicly traded, and may be less liquid than those that are publicly traded. At times, such securities cannot be readily bought or sold and the Fund might be unable to acquire or dispose of such securities promptly or at reasonable prices, which may result in a loss to the Fund. A restricted security that was liquid at the time of purchase may subsequently become illiquid.

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 or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. 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.

Fixed Income and Market Risk — The fixed income markets can be volatile, and the value of securities, futures, and other instruments correlated with these markets may fluctuate dramatically from day-to-day. Fixed income markets are subject to adverse issuer, political, regulatory, market or economic developments, as well as developments that impact specific economic sectors, industries or segments of the market. Further, fixed income securities in the Index may underperform other fixed income investments that track other markets, segments and sectors. Volatility in the markets and/or market developments may cause the value of an investment in the Fund to decrease.

Industrial Industry Debt Risk — The Fund is subject to risks related to the debt issued by companies in the industrial economic sector to the same extent as the Index is so concentrated, including effects on issuer credit from: supply and demand both for their specific product or service and for industrial sector products in general; decline in demand for products due to rapid technological developments and frequent new product introduction; government regulation, world events and economic conditions; and risks for environmental damage and product liability claims.

Liquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the securities or financial instruments 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 or financial instruments 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 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 — The Fund’s shares are listed for trading on the BATS Exchange 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 and supply and demand for shares. ProShare Advisors cannot predict whether shares will trade above, below or at a price equal to the value of the Fund’s holdings. Because of the nature of high yield bonds, shares may typically trade at a larger premium or discount to the value of the Fund’s holdings than shares of many other ETFs. The Fund’s investment results are measured based upon the daily net asset value (“NAV”) of the Fund. Investors purchasing and selling shares in the secondary market may not experience investment results consistent with those experienced by those creating and redeeming shares directly with the Fund.

Portfolio Turnover Risk — 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. Such activity may have a particularly significant impact on funds (like the Fund) that seek long exposure to high yield bonds.

Short Sale Exposure Risk — The Fund may seek inverse or “short” exposure through financial instruments such as futures contracts, which may cause the Fund to be exposed to certain risks associated with selling securities short. These risks include, under certain market conditions, an increase in the volatility and decrease in the liquidity of securities underlying the short position, which may lower the Fund’s return, result in a loss, have the effect of limiting the Fund’s ability to obtain inverse exposure through financial instruments such as futures contracts, or require the Fund to seek inverse exposure through alternative investment strategies that may be less desirable or may be more costly to implement. To the extent that, at any particular point in time, the securities underlying the short position may be thinly traded or have a limited market, including due to regulatory action, the Fund may be unable to meet its investment objective due to a lack of available securities or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. Obtaining inverse exposure through these instruments may be considered an aggressive investment technique.

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 if market quotations were used. In addition, there is no assurance that a Fund could sell a portfolio security for the value established for it at any time, and it is possible that a Fund would incur a loss because a portfolio security is sold at a discount to its established value.
