Risks and Uncertainties [Abstract] |
Risk | NOTE 8 – RISK Correlation and Compounding Risk The Geared Funds do not seek to achieve their stated investment objective over a period of time greater than a single day (as measured from NAV calculation time to NAV calculation time). The return of a Geared Fund for a period longer than a single day is the result of its return for each day compounded over the period and usually will differ in amount and possibly even direction from one-half the inverse (-0.5x), the inverse (-1x), two times the inverse (-2x), one and one-half times (1.5x) the return or two times (2x) the return of the Geared Fund’s benchmark for the period. A Geared Fund will lose money if its benchmark performance is flat over time, and it is possible for a Geared Fund to lose money over time even if the performance of its benchmark increases (or decreases in the case of Short or UltraShort), as a result of daily rebalancing, the benchmark’s volatility, compounding, and other factors. Compounding is the cumulative effect of applying investment gains and losses and income to the principal amount invested over time. Gains or losses experienced over a given period will increase or reduce the principal amount invested from which the subsequent period’s returns are calculated. The effects of compounding will likely cause the performance of a Geared Fund to differ from the Geared Fund’s stated multiple times the return of its benchmark for the same period. The effect of compounding becomes more pronounced as benchmark volatility and holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in a Geared Fund is held and the volatility of the benchmark during the holding period of an investment in the Geared Fund. Longer holding periods, higher benchmark volatility, inverse exposure and greater leverage each affect the impact of compounding on a Geared Fund’s returns. Daily compounding of a Geared Fund’s investment returns can dramatically and adversely affect its longer-term performance during periods of high volatility. Volatility may be at least as important to a Geared Fund’s return for a period as the return of the Geared Fund’s underlying benchmark. The Matching VIX Funds seek to achieve their stated investment objective over time. Each Ultra and UltraShort Fund uses leverage and should produce daily returns that are more volatile than that of its benchmark. For example, the daily return of an Ultra with a 1.5x or 2x multiple should be approximately one and one-half or two times as volatile on a daily basis as is the return of a fund with an objective of matching the same benchmark. The daily return of an UltraShort Fund is designed to return two times the inverse (-2x) of the return that would be expected of a fund with an objective of matching the same benchmark. The Geared Funds are not appropriate for all investors and present significant risks not applicable to other types of funds. The Leveraged Funds use leverage and are riskier than similarly benchmarked exchange-traded funds that do not use leverage. An investor should only consider an investment in a Geared Fund if he or she understands the consequences of seeking daily leveraged, daily inverse or daily inverse leveraged investment results. Shareholders who invest in the Funds should actively manage and monitor their investments, as frequently as daily. While the Funds seek to meet their investment objectives, there is no guarantee they will do so. Factors that may affect a Fund’s ability to meet its investment objective include: (1) the Sponsor’s ability to purchase and sell Financial Instruments in a manner that correlates to a Fund’s objective; (2) an imperfect correlation between the performance of Financial Instruments held by a Fund and the performance of the applicable benchmark; (3) bid-ask spreads on such Financial Instruments; (4) fees, expenses, transaction costs, financing costs associated with the use of Financial Instruments and commission costs; (5) holding or trading instruments in a market that has become illiquid or disrupted; (6) a Fund’s Share prices being rounded to the nearest cent and/or valuation methodology; (7) changes to a benchmark Index that are not disseminated in advance; (8) the need to conform a Fund’s portfolio holdings to comply with investment restrictions or policies or regulatory or tax law requirements; (9) early and unanticipated closings of the markets on which the holdings of a Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions; (10) accounting standards; and (11) differences caused by a Fund obtaining exposure to only a representative sample of the components of a benchmark, over weighting or under weighting certain components of a benchmark or obtaining exposure to assets that are not included in a benchmark. A number of factors may affect a Geared Fund’s ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that a Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent a Geared Fund from achieving its investment objective. In order to achieve a high degree of correlation with their underlying benchmarks, the Geared Funds seek to rebalance their portfolios daily to keep exposure consistent with their investment objectives. Being materially under- or over-exposed to the benchmark may prevent such Geared Funds from achieving a high degree of correlation with such benchmark. Market disruptions or closure, large amounts of assets into or out of the Geared Funds, regulatory restrictions, extreme market volatility, and other factors will adversely affect such Funds’ ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by the benchmarks’ movements during each day. Other things being equal, more significant movement in the value of its benchmark up or down will require more significant adjustments to a Fund’s portfolio. Because of this, it is unlikely that the Geared Funds will be perfectly exposed (i.e., -0.5x, -1x, -2x, 1.5x, or 2x, as applicable) to its benchmark at the end of each day, and the likelihood of being materially under- or over-exposed is higher on days when the benchmark levels are volatile near the close of the trading day. Each Geared Fund seeks to rebalance its portfolio on a daily basis. The time and manner in which a Geared Fund rebalances its portfolio may vary from day to day depending upon market conditions and other circumstances at the discretion of the Sponsor. Unlike other funds that do not rebalance their portfolios as frequently, each Geared Fund may be subject to increased trading costs associated with daily portfolio rebalancing in order to maintain appropriate exposure to the underlying benchmarks. Counterparty Risk Each Fund may use derivatives such as swap agreements and forward contracts (collectively referred to herein as “derivatives”) in the manner described herein as a means to achieve their respective investment objectives. The use of derivatives by a Fund exposes the Fund to counterparty risks. Regulatory Treatment Derivatives are generally traded in OTC markets and have only recently become subject to comprehensive regulation in the United States. Cash-settled forwards are generally regulated as “swaps”, whereas physically settled forwards are generally not subject to regulation (in the case of commodities other than currencies) or subject to the federal securities laws (in the case of securities). Title VII of the Dodd-Frank Act (“Title VII”) created a regulatory regime for derivatives, with the CFTC responsible for the regulation of swaps and the SEC responsible for the regulation of “security-based swaps.” The SEC requirements have largely yet to be made effective, but the CFTC requirements are largely in place. The CFTC requirements have included rules for some of the types of transactions in which the Funds will engage, including mandatory clearing and exchange trading, reporting, and margin for OTC swaps. Title VII also created new categories of regulated market participants, such as “swap dealers,” “security-based swap dealers,” “major swap participants,” and “major security-based swap participants” who are, or will be, subject to significant new capital, registration, recordkeeping, reporting, disclosure, business conduct and other regulatory requirements. The regulatory requirements under Title VII continue to be developed and there may be further modifications that could materially and adversely impact the Funds, the markets in which a Fund trades and the counterparties with which the Fund engages in transactions. As noted, the CFTC rules may not apply to all of the swap agreements and forward contracts entered into by the Funds. Investors, therefore, may not receive the protection of CFTC regulation or the statutory scheme of “the Commodity Exchange Act (the “CEA”) in connection with each Fund’s swap agreements or forward contracts. The lack of regulation in these markets could expose investors to significant losses under certain circumstances, including in the event of trading abuses or financial failure by participants. Counterparty Credit Risk The Funds will be subject to the credit risk of the counterparties to the derivatives. In the case of cleared derivatives, the Funds will have credit risk to the clearing corporation in a similar manner as the Funds would for futures contracts. In the case of OTC derivatives, the Funds will be subject to the credit risk of the counterparty to the transaction – typically a single bank or financial institution. As a result, a Fund is subject to increased credit risk with respect to the amount it expects to receive from counterparties to OTC derivatives entered into as part of that Fund’s principal investment strategy. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, a Fund could suffer significant losses on these contracts and the value of an investor’s investment in a Fund may decline. The Funds have sought to mitigate these risks by generally requiring that the counterparties for each Fund agree to post collateral for the benefit of the Fund, marked to market daily, subject to certain minimum thresholds. However, there are no limitations on the percentage of assets each Fund may invest in swap agreements or forward contracts with a particular counterparty. To the extent any such collateral is insufficient or there are delays in accessing the collateral, the Funds will be exposed to counterparty risk as described above, including possible delays in recovering amounts as a result of bankruptcy proceedings. The Funds typically enter into transactions only with major global financial institutions. OTC derivatives of the type that may be utilized by the Funds are generally less liquid than futures contracts because they are not traded on an exchange, do not have uniform terms and conditions, and are generally entered into based upon the creditworthiness of the parties and the availability of credit support, such as collateral, and in general, are not transferable without the consent of the counterparty. These agreements contain various conditions, events of default, termination events, covenants and representations. The triggering of certain events or the default on certain terms of the agreement could allow a party to terminate a transaction under the agreement and request immediate payment in an amount equal to the net positions owed to the party under the agreement. For example, if the level of the Fund’s benchmark has a dramatic intraday move that would cause a material decline in the Fund’s NAV, the terms of the swap may permit the counterparty to immediately close out the transaction with the Fund. In that event, it may not be possible for the Fund to enter into another swap or to invest in other Financial Instruments necessary to achieve the desired exposure consistent with the Fund’s objective. This, in turn, may prevent the Fund from achieving its investment objective, particularly if the level of the Fund’s benchmark reverses all or part of its intraday move by the end of the day. In addition, cleared derivatives benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. To the extent the Fund enters into cleared swap transactions, the Fund will deposit collateral with a FCM in cleared swaps customer accounts, which are required by CFTC regulations to be separate from its proprietary collateral posted for cleared swaps transactions. Cleared swap customer collateral is subject to regulations that closely parallel the regulations governing customer segregated funds for futures transactions but provide certain additional protections to cleared swaps collateral in the event of a clearing broker or clearing broker customer default. For example, in the event of a default of both the clearing broker and a customer of the clearing broker, a clearing house is only permitted to access the cleared swaps collateral in the legally separate (but operationally comingled) account of the defaulting cleared swap customer of the clearing broker, as opposed to the treatment of customer segregated funds, under which the clearing house may access all of the commingled customer segregated funds of a defaulting clearing broker. Derivatives entered into directly between two counterparties do not necessarily benefit from such protections, particularly if entered into with an entity that is not registered as a “swap dealer” with the CFTC. This exposes the Funds to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Funds to suffer a loss. The Sponsor regularly reviews the performance of its counterparties for, among other things, creditworthiness and execution quality. In addition, the Sponsor periodically considers the addition of new counterparties and the counterparties used by a Fund may change at any time. Each day, the Funds disclose their portfolio holdings as of the prior Business Day. Each Fund’s portfolio holdings identifies its counterparties, as applicable. This portfolio holdings information may be accessed through the web on the Sponsor’s website at www.ProShares.com. Each counterparty and/or any of its affiliates may be an Authorized Participant or shareholder of a Fund, subject to applicable law. The counterparty risk for cleared derivatives transactions is generally lower than for OTC derivatives. Once a transaction is cleared, the clearing organization is substituted and is a Fund’s counterparty on the derivative. The clearing organization guarantees the performance of the other side of the derivative. Nevertheless, some risk remains, as there is no assurance that the clearing organization, or its members, will satisfy its obligations to a Fund. Leverage Risk The Leveraged Funds may utilize leverage in seeking to achieve their respective investment objectives and will lose more money in market environments adverse to their respective daily investment objectives than funds that do not employ leverage. The use of leveraged and/or inverse leveraged positions increases the risk of total loss of an investor’s investment, even over periods as short as a single day. For example, because the UltraShort Funds and Ultra Funds (except for the Ultra VIX Short-Term Futures ETF which includes a one and one-half times multiplier) include a two times the inverse (-2x), or a two times (2x) multiplier, a single-day movement in the relevant benchmark approaching 50% at any point in the day could result in the total loss or almost total loss of an investor’s investment if that movement is contrary to the investment objective of the Fund in which an investor has invested, even if such Fund’s benchmark subsequently moves in an opposite direction, eliminating all or a portion of the movement. This would be the case with downward single-day or intraday movements in the underlying benchmark of an Ultra Fund or upward single-day or intraday movements in the benchmark of an UltraShort Fund, even if the underlying benchmark maintains a level greater than zero at all times. Liquidity Risk Financial Instruments cannot always be liquidated at the desired price. It is difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. A market disruption can also make it difficult to liquidate a position or find a swap or forward contract counterparty at a reasonable cost. Market illiquidity may cause losses for the Funds. The large size of the positions which the Funds may acquire increases the risk of illiquidity by both making their positions more difficult to liquidate and increasing the losses incurred while trying to do so. Any type of disruption or illiquidity will potentially be exacerbated due to the fact that the Funds will typically invest in Financial Instruments related to one benchmark, which in many cases is highly concentrated. “Contango” and “Backwardation” Risk In Funds that hold futures contracts, as the futures contracts near expiration, they are generally replaced by contracts that have a later expiration. Thus, for example, a contract purchased and held in November 2019 may specify a January 2020 expiration. As that contract nears expiration, it may be replaced by selling the January 2020 contract and purchasing the contract expiring in March 2020. This process is referred to as “rolling.” Rolling may have a positive or negative impact on performance. For example, historically, the prices of certain types of futures contracts have frequently been higher for contracts with shorter-term expirations than for contracts with longer-term expirations, which is referred to as “backwardation.” In these circumstances, absent other factors, the sale of the January 2020 contract would take place at a price that is higher than the price at which the March 2020 contract is purchased, thereby creating a gain in connection with rolling. While certain types of futures contracts have historically exhibited consistent periods of backwardation, backwardation will likely not exist in these markets at all times. The presence of contango (where prices of contracts are higher in the distant delivery months than in the nearer delivery months due to the costs of long-term storage of a physical commodity prior to delivery or other factors) in certain futures contracts at the time of rolling would be expected to adversely affect an Ultra Fund or a Matching VIX Fund that invests in such futures, and positively affect a Short Fund or an UltraShort Fund that invests in such futures. Similarly, the presence of backwardation in certain futures contracts at the time of rolling such contracts would be expected to adversely affect the Short Funds and UltraShort Funds, and positively affect the Ultra Funds and Matching VIX Funds. Since the introduction of VIX futures contracts, there have frequently been periods where VIX futures prices reflect higher expected volatility levels further out in time. This can result in a loss from “rolling” the VIX futures to maintain the constant weighted average maturity of the applicable VIX Futures Index. Losses from exchanging a lower priced VIX future for a higher priced longer-term future in the rolling process would adversely affect the value of each VIX Futures Index and, accordingly, decrease the return of the Ultra VIX Short-Term Futures ETF and the Matching VIX Funds. Gold and silver have historically exhibited persistent “contango” markets rather than backwardation. Natural gas, like crude oil, moves in and out of backwardation and contango but historically has been in contango most commonly. In April 2020, the market for crude oil futures contracts experienced a period of “extraordinary contango” that resulted in a negative price in the May 2020 WTI crude oil futures contract. The futures contracts held by the Funds may experience a period of extraordinary contango in the future. If all or a significant portion of the futures contracts held by an Ultra Fund at a future date were to reach a negative price, investors in such Fund could lose their entire investment. If such event were to occur, and the price of the applicable futures contracts subsequently reversed, investors in the Short or an UltraShort Fund could suffer significant losses or lose their entire investment. The effects of rolling futures contracts under extraordinary contango market conditions generally are more exaggerated than rolling futures contracts under contango market conditions and may cause significant losses. Change to Investment Strategies In anticipation of the benchmark’s upcoming roll, and in order to help manage the impact of recent extraordinary conditions and volatility in the markets for crude oil and related Financial Instruments, each Oil Fund adjusted its portfolio exposure as described below.
| • |  | By the close of business on Tuesday, June 30, 2020, ProShares Ultra Bloomberg Crude Oil and ProShares UltraShort Bloomberg Crude Oil (the “Oil Funds”), had transitioned approximately half of its exposure to the September 2020 WTI crude oil futures contract into exposure to the October 2020 WTI crude oil futures contract. As a result of this transition, each Fund had approximately 1/3 of its portfolio exposed to the September 2020 WTI crude oil futures contract, approximately 1/3 of its portfolio exposed to the October 2020 WTI crude oil futures contract, and approximately 1/3 of its portfolio exposed to the December 2020 WTI crude oil futures contract on the close of business on Tuesday, June 30, 2020.
| • |  | In addition, by the close of business on Wednesday, July 1, 2020, each Oil Fund had transitioned the remaining portion of its exposure to the September 2020 WTI crude oil futures contract into exposure to the November 2020 WTI crude oil futures contract. As a result of this transition, each Fund had approximately 1/3 of its portfolio exposed to the October 2020 WTI crude oil futures contract, approximately 1/3 of its portfolio exposed to the November 2020 WTI crude oil futures contract, and approximately 1/3 of its portfolio exposed to the December 2020 WTI crude oil futures contract on the close of business on Wednesday, July 1, 2020.
Following this portfolio transition each Oil Fund had exposure to WTI crude oil futures contracts that are not included in the current benchmark. The performance of each Fund should not be expected to correspond to two times (2x), or two times the inverse (-2x), as applicable, of the daily performance of its current benchmark. Each Fund’s performance could differ significantly from its stated investment objective. In addition, to the extent an Oil Fund has exposure to longer-dated crude oil futures contracts or other Financial Instruments, the performance of the Fund should be expected to deviate to a greater extent from the “spot” price of crude oil than if the Fund had exposure to shorter-dated futures contracts or Financial Instruments. For these and other reasons, the Oil Funds should be expected to perform very differently from the spot price of crude oil and may underperform investments that are linked to the “spot” price of crude oil. Change to the Oil Funds Benchmark Index Effective September 17, 2020, the Oil Funds changed their benchmark from the Bloomberg WTI Crude Oil Subindex SM to the Bloomberg Commodity Balanced WTI Crude Oil Index SM (the “New Benchmark”). The investment objective of each of these two funds is to seek daily investment results, before fees and expenses, that correspond either to two times (2x) or two times the inverse (-2x), as applicable, of the daily performance of the New Benchmark for a single day, not for any other period. In order to have exposure to the WTI crude oil futures contracts included in the New Benchmark in a manner designed to achieve its respective investment objective by the beginning of business on September 17, 2020, each Oil Fund transitioned half of its then current exposure to the December 2020 WTI crude oil futures contract into exposure to the December 2021 WTI crude oil futures contract at the close of business on September 16, 2020. As a result of this transition, each Oil Fund had approximately 1/3 of its portfolio exposed to the December 2020 WTI crude oil futures contract, approximately 1/3 of its portfolio exposed to the June 2021 WTI crude oil futures contract, and approximately 1/3 of its portfolio exposed to the December 2021 WTI crude oil futures contract at the close of business on September 16, 2020. Description of the New Benchmark The New Benchmark aims to track the performance of three separate contract schedules for WTI Crude Oil futures traded on NYMEX. The contract schedules are equally-weighted in the New Benchmark (1/3 each) at each semi-annual reset in March and September. At each reset date, one-third of the New Benchmark is designated to follow a monthly roll schedule. Each month this portion of the New Benchmark rolls from the current futures contract (called “Lead” by Bloomberg, and which expires one month out) into the following month’s contract (called “Next” by Bloomberg and which expires two months out). The second portion of the New Benchmark is always designated to be in a June contract, and follows an annual roll schedule in March of each year in which the June contract expiring in the current year is rolled into the June contract expiring the following year. The remaining portion is always designated to be in a December contract, and follows an annual roll schedule in September of each year in which the December contract expiring in the current year is rolled into the December contract expiring the following year. The weighting (i.e., percentage) of each of the three contract schedules included in the New Benchmark fluctuates above or below one-third between the semi-annual reset dates due to changing futures prices and the impact of rolling the futures positions. As a result, the weighting of each contract in the New Benchmark will “drift” away from equal weighting. The New Benchmark reflects the cost of rolling the futures contracts included in the New Benchmark, without regard to income earned on cash positions. The New Benchmark is not linked to the “spot” price of WTI crude oil. The methodology for determining the composition of the New Benchmark and for calculating its level may be changed at any time by Bloomberg without notice. The daily performance of the New Benchmark is published by Bloomberg Finance L.P. and is available under the Bloomberg ticker symbol: BCBCLI Index. Natural Disaster/Epidemic Risk Natural or environmental disasters, such as earthquakes, fires, floods, hurricanes, tsunamis and other severe weather-related phenomena generally, and widespread disease, including pandemics and epidemics (for example, the novel coronavirus COVID-19), have been and can be highly disruptive to economies and markets and have recently led, and may continue to lead, to increased market volatility and significant market losses. Such natural disaster and health crises could exacerbate political, social, and economic risks previously mentioned, and result in significant breakdowns, delays, shutdowns, social isolation, and other disruptions to important global, local and regional supply chains affected, with potential corresponding results on the operating performance of the Funds and their investments. A climate of uncertainty and panic, including the contagion of infectious viruses or diseases, may adversely affect global, regional, and local economies and reduce the availability of potential investment opportunities, and increases the difficulty of performing due diligence and modeling market conditions, potentially reducing the accuracy of financial projections. Under these circumstances, the Funds may have difficulty achieving their investment objectives which may adversely impact performance. Further, such events can be highly disruptive to economies and markets, significantly disrupt the operations of individual companies (including, but not limited to, the Funds’ Sponsor and third party service providers), sectors, industries, markets, securities and commodity exchanges, currencies, interest and inflation rates, credit ratings, investor sentiment, and other factors affecting the value of the Funds’ investments. These factors can cause substantial market volatility, exchange trading suspensions and closures and can impact the ability of the Funds to complete redemptions and otherwise affect Fund performance and Fund trading in the secondary market. A widespread crisis may also affect the global economy in ways that cannot necessarily be foreseen at the current time. How long such events will last and whether they will continue or recur cannot be predicted. Impacts from these events could have significant impact on a Fund’s performance, resulting in losses to your investment. Risk that Current Assumptions and Expectations Could Become Outdated As a Result of Global Economic Shocks The onset of the novel coronavirus (COVID-19) has caused significant shocks to global financial markets and economies, with many governments taking extreme actions to slow and contain the spread of COVID-19. These actions have had, and likely will continue to have, a severe economic impact on global economies as economic activity in some instances has essentially ceased. Financial markets across the globe are experiencing severe distress at least equal to what was experienced during the global financial crisis in 2008. In March 2020, U.S. equity markets entered a bear market in the fastest such move in the history of U.S. financial markets. Contemporaneous with the onset of the COVID-19 pandemic in the US, oil experienced shocks to supply and demand, impacting the price and volatility of oil. The global economic shocks being experienced as of the date hereof may cause the underlying assumptions and expectations of the Funds to become outdated quickly or inaccurate, resulting in significant losses. Change to the VIX Funds Benchmark Indices Change to VIX Futures Contracts Settlement Time \ Index Methodology. On Monday, October 26, 2020, the Chicago Futures Exchange (a subsidiary of the Chicago Board Options Exchange) changed the settlement time for the VIX futures contracts in which the Funds invest from 4:15 p.m. (Eastern Time) to 4:00 p.m. (Eastern Time). As a result, on Monday, October 26, 2020, S&P Dow Jones Indices revised the index methodology for the S&P 500 ® VIX Mid-Term Futures Index, the benchmark for ProShares VIX Mid-Term Futures ETF, and the S&P 500 ® VIX Short-Term Futures Index, the benchmark for ProShares VIX Short-Term Futures ETF, ProShares Ultra VIX Short-Term Futures ETF and ProShares Short VIX Short-Term Futures ETF, to reflect the new settlement time. Change to the Fund’s Net Asset Value (“NAV”) Calculation Time. As a result of these changes to the settlement time for VIX futures contracts and the Index methodology, on Monday, October 26, 2020 each Fund changed its NAV calculation time from 4:15 p.m. (Eastern Time) to 4:00 p.m. (Eastern Time). Additional information about the calculation of NAV is included in each Fund’s Prospectus. Change to the VIX Funds Exchange Listing. On December 16, 2020, each Fund transferred its listing from NYSE Arca to the Cboe BZX Exchange.
