This may sound like an unfair system to those who are used to trading with confidence that their profits are settled in full, but it's a compromise that has been made in order to offer the high leverage. If you want to guarantee that your profits are not reduced by any socialised loss, then use CryptoFacilities or Coinpit. They use a "termination" procedure in the event of a margin call not being filled. This simply terminates the contract and sends the portfolio value of the losing counterparty to the winning counterparty. It's worth noting that the system has been incredibly robust, with very minimal socialised losses being triggered on OKCoin and none on BitMEX as of November 2015.
The legal status of cryptocurrencies varies substantially from country to country and is still undefined or changing in many of them. While some countries have explicitly allowed their use and trade, others have banned or restricted it. According to the Library of Congress, an "absolute ban" on trading or using cryptocurrencies applies in eight countries: Algeria, Bolivia, Egypt, Iraq, Morocco, Nepal, Pakistan, and the United Arab Emirates. An "implicit ban" applies in another 15 countries, which include Bahrain, Bangladesh, China, Colombia, the Dominican Republic, Indonesia, Iran, Kuwait, Lesotho, Lithuania, Macau, Oman, Qatar, Saudi Arabia and Taiwan. In the United States and Canada, state and provincial securities regulators, coordinated through the North American Securities Administrators Association, are investigating "bitcoin scams" and ICOs in 40 jurisdictions.
Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking and economic systems such as the Federal Reserve System, corporate boards or governments control the supply of currency by printing units of fiat money or demanding additions to digital banking ledgers. In case of decentralized cryptocurrency, companies or governments cannot produce new units, and have not so far provided backing for other firms, banks or corporate entities which hold asset value measured in it. The underlying technical system upon which decentralized cryptocurrencies are based was created by the group or individual known as Satoshi Nakamoto.
When a Fund purchases or sells a futures contract, or buys or sells an option thereon, the Fund “covers” its position. To cover its position, a Fund may enter into an offsetting position, earmark or segregate with its custodian bank or on the official books and records of the Fund cash or liquid instruments (marked-to-market on a daily basis) that, when added to any amounts deposited with a futures commission merchant as margin, are equal to the market value of the futures contract or otherwise “cover” its position. When required by law, a Fund will segregate liquid assets in an amount equal to the value of the Fund’s total assets committed to the consummation of such futures contracts. Obligations under futures contracts so covered will not be considered senior securities for purposes of a Fund’s investment restriction concerning senior securities.
A Fund will incur a loss as a result of a short sale if the price of the security increases between the date of the short sale and the date on which the Fund replaces the borrowed security. A Fund will realize a gain if the price of the security declines in price between those dates. The amount of any gain will be decreased, and the amount of any loss will be increased, by the amount of the premium, dividends or interest a Fund may be required to pay, if any, in connection with a short sale.
The first decentralized cryptocurrency, bitcoin, was created in 2009 by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, as its proof-of-work scheme. In April 2011, Namecoin was created as an attempt at forming a decentralized DNS, which would make internet censorship very difficult. Soon after, in October 2011, Litecoin was released. It was the first successful cryptocurrency to use scrypt as its hash function instead of SHA-256. Another notable cryptocurrency, Peercoin was the first to use a proof-of-work/proof-of-stake hybrid. IOTA was the first cryptocurrency not based on a blockchain, and instead uses the Tangle. Many other cryptocurrencies have been created though few have been successful, as they have brought little in the way of technical innovation. On 6 August 2014, the UK announced its Treasury had been commissioned to do a study of cryptocurrencies, and what role, if any, they can play in the UK economy. The study was also to report on whether regulation should be considered.
Bitcoin is a relatively new type of currency—a digital or cryptocurrency secured through cryptography, or codes that can’t be read without a key. Traditional currencies are made up of paper bills and coins. Unlike traditional currencies, the bitcoin is not issued by any central government. Rather, a computer algorithm determines how many bitcoins are produced and added to the economy. This is much different than a traditional currency, where central banks typically determine how much money to print.
The price of bitcoin has been subject to periods of high volatility. As a result, the CFE and CME have established margin requirements for bitcoin futures contracts at levels substantially higher than the margin requirements for more established futures contracts. The increased margin requirements may result in much higher upfront costs for the Funds. Market participants may be deterred from incorporating bitcoin futures contracts into their investment strategies due to these higher costs and other limitations created by the high margin requirements, such as the limit on their ability to use leverage to invest in bitcoin futures contracts. A reduction in the adoption of the bitcoin futures contracts will negatively impact the market for bitcoin futures contracts and could negatively impact the performance of the Funds. In addition, the continued volatility in the price of bitcoin may result in further increases to the margin requirements for bitcoin futures contracts by the CFE and CME, as well as some FCMs imposing margin requirements on their customers in amounts that are steeper than the margin required by the exchanges.
Assume there is 0 contracts open and 2 traders, and a new futures contract expiring in 7 days opens. You can "create" a contract by putting a limit sell order in the orderbook at a given price. If someone market buys that limit order, an open contract is created between you and the other trader. This is how you can go from a position of 0 to a negative exposure just by selling a contract.
price of a particular asset, whether a Fund will realize a gain or loss from the purchase or writing (sale) of options on an index depends upon movements in the level of prices for specific underlying assets generally or, in the case of certain indexes, in an industry or market segment. A Fund will not enter into an option position that exposes the Fund to an obligation to another party, unless the Fund either (i) owns an offsetting position in the underlying securities or other options and/or (ii) earmarks or segregates with the Fund’s custodian bank cash or liquid instruments that, when added to the premiums deposited with respect to the option, are equal to the market value of the underlying assets not otherwise covered.
Shareholders that are U.S. persons and own, directly or indirectly, more than 50% of a Fund could be required to report annually their “financial interest” in the Fund’s “foreign financial accounts,” if any, on FinCEN Form 114, Report of Foreign Bank and Financial Accounts (“FBAR”). Shareholders should consult a tax advisor, and persons investing in a Fund through an intermediary should contact their intermediary, regarding the applicability to them of this reporting requirement.
Each Fund may invest in real estate investment trusts (“REITs”). Equity REITs invest primarily in real property, while mortgage REITs invest in construction, development and long-term mortgage loans. Their value may be affected by changes in the value of the underlying property of the REIT, the creditworthiness of the issuer, property taxes, interest rates, and tax and regulatory requirements, such as those relating to the environment. REITs are dependent upon management skill, are not diversified and are subject to heavy cash flow dependency, default by borrowers, self-liquidation and the possibility of failing to qualify for tax-free pass-through of income under the Code and failing to maintain exempt status under the 1940 Act.
• Bitcoin is available for trading 24-hours a day globally and, as such, the price of bitcoin may change dramatically when the market for bitcoin futures contracts is closed or when Fund shares are not available for trading on the Exchange. The price of bitcoin may change dramatically at times when investors are unable to buy or sell Fund shares.
Cryptocurrencies allow traders to diversify their investment portfolio, as their price is mainly determined by demand and supply; Their value has a low correlation to national economies or political scenarios. Once Bitcoin surpassed the price of gold in 2017, US markets introduced 2 ETFs on Bitcoin and drew more and more institutional money into the world of cryptocurrencies. In 2017, Indian PM Narendra Modi has announced the gradual replacement of paper currency with electronic currency; In March 2018, the Marshall Islands announced that they would be introducing a cryptocurrency to replace US dollars as their main currency; other central banks are investigating the adoption of blockchain-like technologies… in short cryptocurrencies are probably here to stay. A growing number of crypto investors all over the world have already discovered the benefits:
The following individuals have responsibility for the day-to-day management of each Fund as set forth in the Summary Prospectus relating to such Fund. The Portfolio Managers’ business experience for the past five years is listed below. The SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership of securities in each Fund.
risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. If such a default occurs, a Fund will have contractual remedies pursuant to the swap agreements, but such remedies may be subject to bankruptcy and insolvency laws that could affect the Fund’s right as a creditor. The counterparty risk for cleared swaps is generally lower than for uncleared over-the-counter swaps because generally a clearing organization becomes substituted for each counterparty to a cleared swap agreement and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations. However, there can be no assurance that the clearing organization, or its members, will satisfy its obligations to a Fund. Upon entering into a cleared swap, a Fund may be required to deposit with the broker an amount of cash or cash equivalents in the range of approximately 3% to 6% of the notional amount for CDS on high yield debt issuers and 1% to 5% for CDS on investment grade debt issuers (this amount is subject to change by the clearing organization that clears the trade). This amount, known as “initial margin,” is in the nature of a performance bond or good faith deposit on the cleared swap and is returned to a Fund upon termination of the swap, assuming all contractual obligations have been satisfied. Subsequent payments, known as “variation margin” to and from the broker will be made daily as the price of the swap fluctuates, making the long and short position in the swap contract more or less valuable, a process known as “marking-to-market.” The premium (discount) payments are built into the daily price of the swap and thus are amortized through the variation margin. The variation margin payment also includes the daily portion of the periodic payment stream.
During the fiscal year ended May 31, 2017, the Advisor recouped $161,605 from UltraPro S&P 500 Fund pursuant to an Investment Advisory Agreement and the Expense Limitation Agreement between the Advisor and the Trust, on behalf of the Fund. During the fiscal year ended May 31, 2016, the Advisor recouped $155,882 from the UltraPro S&P 500 Fund pursuant to an Investment Advisory Agreement and the Expense Limitation Agreement between the Advisor and the Trust, on behalf of the Fund. During the fiscal year ended May 31, 2015, the Advisor recouped $259,539 from the UltraPro S&P 500 Fund pursuant to an Investment Advisory Agreement and the Expense Limitation Agreement between the Advisor and the Trust, on behalf of the Fund.
Update 1st October 2018: The cryptocurrency market has been volatile as ever over the last 6 months. Unless you are a skilled trader, it is harder to make money in a bear market than in a bull market – and we have been in a bear market for some time now. Personally, I have stopped trading and I am now focussing on growing my portfolio passively using a cryptocurrency trading bot – you can find out more about this here. If you are new to crypto, read on!
Several factors may affect a Fund’s ability to achieve a high degree of correlation with its benchmark. Among these factors are: (i) a Fund’s fees and expenses, including brokerage (which may be increased by high portfolio turnover) and the costs associated with the use of derivatives; (ii) less than all of the securities underlying a Fund’s benchmark being held by the Fund and/or securities not included in its benchmark being held by a Fund; (iii) an imperfect correlation between the performance of instruments held by a Fund, such as futures contracts, and the performance of the underlying securities in a benchmark; (iv) bid-ask spreads (the effect of which may be increased by portfolio turnover); (v) holding instruments traded in a market that has become illiquid or disrupted; (vi) a Fund’s share prices being rounded to the nearest cent; (vii) changes to the benchmark that are not disseminated in advance; (viii) the need to conform a Fund’s portfolio holdings to comply with investment restrictions or policies or regulatory or tax law requirements;
Shares will be continuously offered for sale by the Trust through the Distributor only in Creation Units, as described below under “Purchase and Issuance of Creation Units.” Shares in less than Creation Units are not distributed by the Distributor. The Distributor also acts as agent for the Trust. The Distributor will deliver a Prospectus to persons purchasing Shares in Creation Units and will maintain records of both orders placed with it and confirmations of acceptance furnished by it. The Distributor is a broker-dealer registered under the 1934 Act and a member of the Financial Industry Regulatory Authority, Inc. The Distributor has no role in determining the investment policies of the Funds or which securities are to be purchased or sold by the Funds.
When a Fund purchases a put or call option on a futures contract, the Fund pays a premium for the right to sell or purchase the underlying futures contract for a specified price upon exercise at any time during the option period. By writing (selling) a put or call option on a futures contract, a Fund receives a premium in return for granting to the purchaser of the option the right to sell to or buy from the Fund the underlying futures contract for a specified price upon exercise at any time during the option period.
Last night, Cboe XBTSM Bitcoin Futures commenced trading on the Cboe Futures Exchange. The launch was smooth, although our website experienced some issues due to an overwhelming number of hits looking for the trading data. Now that the futures are up and running, it may be time for a brief explanation of how an owner of bitcoins may use futures to hedge their position.
Bitcoin is maintained on the decentralized, open source protocol of the peer-to-peer bitcoin computer network (the “Bitcoin Network”). No single entity owns or operates the Bitcoin Network. The infrastructure of the Bitcoin Network is collectively maintained by a decentralized user base. The Bitcoin Network is accessed through software, and software governs bitcoin’s creation, movement, and ownership. The value of bitcoin is determined in great part by the supply of (which is limited), and demand for, bitcoin in the global exchange markets for the trading of bitcoin (individually, “Bitcoin Exchanges” and collectively, the “Bitcoin Exchange Market”), market expectations for the adoption of bitcoin and the volume of private user-to-user transactions.
Cryptocurrencies have been compared to Ponzi schemes, pyramid schemes and economic bubbles, such as housing market bubbles. Howard Marks of Oaktree Capital Management stated in 2017 that digital currencies were "nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it", and compared them to the tulip mania (1637), South Sea Bubble (1720), and dot-com bubble (1999).
In general, a beneficial owner of Fund Shares who or which is a foreign shareholder is not subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on a sale of shares of the Fund unless (i) such gain effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or and certain other conditions are met, or (iii) the special rules relating to gain attributable to the sale or exchange of “U.S. real property interests” (“USRPIs”) apply to the foreign shareholder’s sale of shares of the Fund (as described below).
The Global Listed Private Equity ETF and the Short Term USD Emerging Markets Bond ETF each pay ProShare Advisors a fee at an annualized rate based on its average daily net assets of 0.50%. The Inflation Expectations ETF pays ProShare Advisors a fee at an annualized rate based on its average daily net assets of 0.55%. The CDS Short North American HY Credit ETF pays ProShare Advisors a fee at an annualized rate based on its average daily net assets of 0.65%. ProShare Advisors manages the investment and the reinvestment of the assets of each of the Funds in accordance with the investment objectives, policies, and limitations of the Fund, subject to the general supervision and control of the Trustees and the Officers of the Trust. ProShare Advisors bears all costs associated with providing these advisory services. Except for the Morningstar Alternatives Solution ETF, ProShare Advisors has contractually agreed to waive investment advisory and management services fees and to reimburse other expenses (exclusive of transaction costs,
• Valuation Risk — In certain circumstances, portfolio holdings may be valued using techniques other than market quotations. The value established for a portfolio holding may be different from what would be produced through the use of another methodology or if it had been priced using market quotations. Portfolio holding 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 holding for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio holding is sold at a discount to its established value.
No, the successful trader is not me. I’ve gotten lucky a few times and I’m still refining and trying out strategies; on the other hand, I’m part of communities of people who trade on a daily basis to grow their portfolios, and while some of the results can be attributed to luck, a majority of it is based on fundamentals, good habits, and experience.
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. Although your actual costs may be higher or lower, based on these assumptions your approximate costs would be:
• Tax Risk — In order to qualify for the special tax treatment accorded a regulated investment company (“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

Shares may be issued in advance of receipt by the Trust of all or a portion of the applicable Deposit Securities as described below. In these circumstances, the initial deposit may have a greater value than the NAV of the Shares on the date the order is placed in proper form because, in addition to the available Deposit Securities, cash must be deposited in an amount equal to the sum of (i) the Balancing Amount, plus (ii) up to 115% of the market value of the undelivered Deposit Securities (the “Additional Cash Deposit”). Additional amounts of cash may be required to be deposited with the Trust, pending delivery of the missing Deposit Securities to the extent necessary to maintain the Additional Cash Deposit with the Trust in an amount up to 115% of the daily mark-to-market value of the missing Deposit Securities. Authorized Participants will be liable to the Trust for the costs incurred by the Trust in connection with any such purchases. These costs will be deemed to include the amount by which the actual purchase price of the Deposit Securities exceeds the market value of such Deposit Securities on the day the purchase order was deemed received by the Distributor plus the brokerage and related transaction costs associated with such purchases. The Trust will return any unused portion of the Additional Cash Deposit once all of the missing Deposit Securities have been properly received by the Custodian or any sub-custodian or purchased by the Trust and deposited into the Trust. In addition, a Transaction Fee, as described below, will be charged in all cases. The delivery of Shares so purchased will occur no later than the third Business Day following the day on which the purchase order is deemed received by the Distributor.
• Developmental risk. Blockchain technology is not a product or service within an individually attributable revenue stream. Blockchain technology may never develop optimized transactional processes that lead to realized economic returns for any company in which the Fund invests. Blockchain Companies that are developing applications of blockchain technology applications may not in fact do so or may not be able to capitalize on those blockchain technologies. The development of new or competing platforms may cause consumers and investors to use alternatives to blockchains.
Pursuant to an investment advisory and management agreement between ProShare Advisors and the Trust on behalf of each Unitary Fee Fund, each Unitary Fee Fund pays ProShare Advisors a fee at an annualized rate based on its average daily net assets as follows: 0.27% for S&P 500 Ex-Energy ETF; 0.27% for S&P 500 Ex-Financials ETF; 0.27% for S&P 500 Ex-Health Care ETF; 0.27% for S&P 500 Ex-Technology ETF; 0.35% for Equities for Rising Rates ETF; 0.30% for Investment Grade—Interest Rate Hedged; 0.35% for S&P 500 Dividend Aristocrats ETF; 0.40% for S&P MidCap 400 Dividend Aristocrats ETF; 0.40% for the Russell 2000 Dividend Growers ETF; 0.45% for Large Cap Core Plus; 0.45% for DJ Brookfield Global Infrastructure ETF; 0.50% for MSCI EAFE Dividend Growers ETF; 0.50% for High Yield—Interest Rate Hedged; 0.55% for MSCI Europe Dividend Growers ETF; 0.60% for MSCI Emerging Markets Dividend Growers ETF; 0.65% for Crude Oil Strategy ETF; 0.65% for Decline of the Retail Store ETF; 0.65% for Long Online/Short Stores ETF; 0.75% for Managed Futures Strategy ETF; 0. % for the Bitcoin Futures Strategy ETF; 0. % for the Short Bitcoin Futures Strategy ETF; 0. % for the Blockchain/Bitcoin Strategy ETF; and 0. % for the Bitcoin Futures/Equity Strategy ETF.
Special rules would apply if a Fund were a qualified investment entity (“QIE”) because it is either a “U.S. real property holding corporation” (“USRPHC”) or would be a USRPHC but for the operation of certain exceptions to the definition of USRPIs described below. Very generally, a USRPHC is a domestic corporation that holds USRPIs the fair market value of which equals or exceeds 50% of the sum of the fair market values of the corporation’s USRPIs, interests in real property located outside the United States, and other trade or business assets. USRPIs generally are defined as any interest in U.S. real property and any interest (other than solely as a creditor) in a USRPHC or, very generally, an entity that has been a USRPHC in the last five years. A Fund that holds, directly or indirectly, significant interests in REITs may be a USRPHC. Interests in domestically controlled QIEs, including REITs and RICs that are QIEs, not-greater-than-10% interests in publicly traded classes of stock in REITs and not-greater-than-5% interests in publicly traded classes of stock in RICs generally are not USRPIs, but these exceptions do not apply for purposes of determining whether a Fund is a QIE.
The proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run difficult hashing algorithms to validate electronic transactions. The scheme is largely dependent on the coin, and there's currently no standard form of it. Some cryptocurrencies use a combined proof-of-work/proof-of-stake scheme.
In general, dividends of net investment income received by corporate shareholders of a Fund may qualify for the 70% dividends-received deduction generally available to corporations to the extent of the amount of eligible dividends received by the Fund from domestic corporations for the taxable year. A dividend received by a Fund will not be treated as a dividend eligible for the dividends-received deduction (1) if it has been received with respect to any share of stock that the Fund has held for less than 46 days (91 days in the case of certain preferred stock) during the 91-day period beginning on the date which is 45 days before the date on which such share becomes ex-dividend with respect to such dividend (during the 181-day period beginning 90 days before such date in the case of certain preferred stock) or (2) to the extent that the Fund is under an obligation (pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property. Moreover, the dividends received deduction may otherwise be disallowed or reduced (1) if the corporate shareholder fails to satisfy the foregoing requirements with respect to its shares of the Fund or (2) by application of various provisions of the Code (for instance, the dividends-received deduction is reduced in the case of a dividend received on debt-financed portfolio stock (generally, stock acquired with borrowed funds)). The corporate alternative minimum tax may disallow the dividends received deduction in certain circumstances.
interest, taxes, dividends (including dividend expenses on securities sold short), litigation, indemnification, expenses associated with investment in other funds as permitted by the then current registration statement, and extraordinary expenses as determined under generally accepted accounting principles) to the extent total annual Fund operating expenses, as a percentage of average daily net assets, exceed 0.95% through September 30, 2018 (0.30% for the Inflation Expectations ETF, 0.60% for the Global Listed Private Equity ETF, 0.50% for the Short Term USD Emerging Markets Bond ETF and the CDS Short North American HY Credit ETF, and 0.75% for the Merger ETF each through September 30, 2018. ProShare Advisors, on behalf of the Morningstar Alternatives Solution ETF, has contractually agreed to waive investment advisory and management services fees and to reimburse other expenses (exclusive of transaction costs, interest, taxes, dividends (including dividend expenses on securities sold short), litigation, indemnification, expenses associated with investment in other funds as permitted by the then current registration statement, and extraordinary expenses as determined under generally accepted accounting principles but inclusive of acquired fund fees and expenses) to the extent total annual Fund operating expenses, as a percentage of average daily net assets, exceed 0.95% 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.
Another huge pain point for institutional investors is portfolio management. Investors face major difficulties in tracking their real time and historical P&L (profits & loss). Our PMS (Portfolio Management System) allows users to see real-time and historical P&L over any time interval, as well as perform real-time monitoring of positions across exchanges and wallets.
• Futures Position Limit Risk — Limits on the amount of futures any one entity can hold may negatively impact the Fund’s ability to meet its investment objective if such limits are reached and exceptions to such limits are not granted. Currently the position limits for bitcoin futures contracts are much lower than they are for most other futures contracts.
Crypto Facilities and the CME Group have been calculating and publishing the Bitcoin Reference Rate (BRR) since November 2016. Such an official rate is a prerequisite of options trading in the traditional markets. The BRR is calculated based on the rates from the biggest exchanges: Bitstamp, GDAX, itBit, and Kraken. More concretely, it is calculated based on all Bitcoin vs. USD trades on the participating exchanges between 3 and 4 p.m. London time. To calculate the BRR, the hour between 3 and 4 is divided into 12 intervals of 5 minutes. For each interval, the volume-weighted median of the Bitcoin price is calculated (statistically, the median, in contrast to the average, prevents single outliers from distorting the price). The BRR is then the average of these 12 median values. More details about the calculation of the BRR can be found in the BRR whitepaper.
