Go To ibkr.com/freedemo 45398txtcx.indd 2 3/2/16 8:39 PM Portfolio Builder Our clients’ investment objectives and risk appetites don’t always ﬁt into cookie cutter portfolios. We launched the Portfolio Builder to make it easy for our clients to assemble portfolios based on independent research providers’ stock picks or fundamental data to design an investment strategy. With easy-to-use backtesting and criteria setting features, allocation of capital is simple. Deﬁne an Investment Strategy Become your own robo-advisor. The Portfolio Builder provides a straight forward approach to crafting an investment strategy, by deﬁning the capital you want to allocate to a given strategy, the amount of leverage, and ﬁltering the universe of securities by user-deﬁned criteria. 11 top buy-side research providers provide rankings for stocks and further ﬁlters can be applied based on fundamental data. Review Backtesting Results As ﬁlters are deﬁned and reﬁned, you can view updates to backtesting results for up to three years. Invest your Capital After conﬁguring the strategy, you can assign an amount to be invested in the strategy and add execution parameters. 45398txtcx.indd 3 3/2/16 8:39 PM 45398txtcx.indd 4 3/2/16 8:39 PM Independent Advisor Tools Financial advisors increasingly have a desire to gain ﬁnancial independence. They’ve worked hard to gain the trust of their clients and we want to help them keep a larger portion of the fees they generate. We thought it made sense to streamline this process: 1 2 3 The ﬁrst step toward independence is for advisors to visit our RIA Compliance Center. Investment advisors are subject to a variety of compliance obligations and we built the Center to help advisors meet their obligations. Advisors can advertise their services to our clients in IB’s Investors’ Marketplace. The Marketplace provides a place for advisors to attract capital to manage, and for IB clients to ﬁnd advisors when they do not wish to manage their investments. Advisors can keep track of their clients in our free Customer Relationship Management tool, seamlessly integrated into Account Management. 45398txtcx.indd 5 3/2/16 8:39 PM Investors’ Marketplace Our brokerage business was built by catering to self-directed traders, investors and institutions who need the most advanced technology and understand the effect costs have on performance. The Investors’ Marketplace is a natural extension of our offering. The Investors’ Marketplace gives our clients one-stop shopping access to investment service providers around the globe. 45398txtcx.indd 6 3/2/16 8:39 PM The Investors’ Marketplace is a groundbreaking online service where investors, ﬁnancial advisors, fund managers, research analysts, technology providers, business developers and administrators can meet and do business together. Investors who may not be interested in self-directed trading can still beneﬁt from IB’s low cost, advanced technology by hiring a ﬁnancial advisor or money manager. In turn, ﬁnancial advisors and money managers can advertise their services to our large, international client base. Additionally, many of our clients are sophisticated, high-net-worth investors who may be both eligible for and interested in investing a portion of their account in hedge funds. Over 1,100 Providers in the Investors’ Marketplace: 433 Investment Services 219 Research 331 Technology 116 Administrative 18 Business Development ...more service providers joining every day. Hedge funds are highly speculative and investors may lose their entire investment. 45398txtcx.indd 7 3/2/16 8:39 PM 2015 Award Winning Technology Rated Best Online Broker, for the fourth consecutive year 1 2015 Winner “Best retail FX platform” 2015 Winner “Best FCM - Innovation” 2015 Winner “Best Cross-Asset Trading Solution” Member NYSE, FINRA, SIPC.

In 2015, Interactive Brokers was named the lowest cost broker for the 11th year in a row by Barron’s.

Once again, we had a record year in terms of increased DARTs, customer accounts, customer equity, and positions and cash balances held by our customers. Had we been able to protect against the impact of the Swiss National Bank’s unprecedented act of removing its peg to the Euro overnight on January 15, which resulted in $119 million of uncollected customer losses, our brokerage proﬁts would have increased by a similar magnitude. What should you expect for the coming year? On the negative side, regulatory pressures are increasing from all directions. The many regulatory agencies acting independently have no way of knowing when the cumulative pressure on any business becomes too great to handle. Currently 9% of our employees work in legal and compliance functions, even though we do not sell our own products and make no investment recommendations. We have expanded these functions substantially over the past few years and only our high level of automation prevents our costs from exploding uncontrollably in this area. The global economy is over-leveraged, leaving little room for reinvigorating demand to spark robust growth. The relentless campaign against economic freedom and success by many in politics, Hollywood and academia slowly stiﬂes the entrepreneurial spirit. Fewer young people start new businesses or seek employment in the ﬁnancial industry. This is not an ideal atmosphere in which to grow a brokerage business, but while our competitors face all these same issues they do not have all the opportunities Interactive Brokers has. Namely, our name recognition and our reputation for fair dealing, industry-low pricing and innovative technology are spreading throughout the globe, attracting new customers at an increasing rate. Basel III banking regulations are forcing the big banks and prime brokers to withdraw services from smaller and medium-sized hedge funds and correspondent clearers, and to raise prices on their remaining customers. The diminishing competition in this space leaves us with a huge opportunity for expansion. Socioeconomic advancement is growing across the world, along with more automated multinational enterprises, and we beneﬁt from the global increase in numbers, wealth and ﬁnancial sophistication of the investor population, especially in Latin America, Eastern Europe and the Far East. In summary, we see Interactive Brokers among a relatively few bright spots in an otherwise stagnating global economy in 2016. Having built our company on the idea that if we automate our platform to service our largest and most demanding customers in each client segment, then our smaller customers will be accommodated at a diminishing cost, we are now in an excellent position to compete and grow faster than any of our peers. This is true whether we seek to service more hedge funds, proprietary trading ﬁrms, registered investment advisors, introducing brokers or individual investors. Accordingly, we look forward to another year of new records and proﬁtable growth.

BUSINESS Overview PART I Interactive Brokers Group, Inc. (‘‘IBG, Inc.’’ or the ‘‘Company’’) is an automated global electronic broker and market maker. We custody and service accounts for hedge and mutual funds, registered investment advisors, proprietary trading groups, introducing brokers and individual investors. We specialize in routing orders while striving to achieve best executions and processing trades in securities, futures, foreign exchange instruments, bonds and mutual funds on more than 100 electronic exchanges and market centers around the world. In the United States (‘‘U.S.’’), we conduct our business primarily from our headquarters in Greenwich, Connecticut and from Chicago, Illinois. Abroad, we conduct our business through offices located in Canada, England, Switzerland, Liechtenstein, India, China (Hong Kong and Shanghai), Japan and Australia. As of December 31, 2015 we had 1,087 employees worldwide. IBG, Inc. is a holding company and our primary assets are our ownership of approximately 15.7% of the membership interests of IBG LLC (the ‘‘Group’’), the current holding company for our businesses. We are the sole managing member of IBG LLC. On May 3, 2007, IBG, Inc. priced its initial public offering (the ‘‘IPO’’) of shares of common stock. In connection with the IPO, IBG, Inc. purchased 10.0% of the membership interests in IBG LLC and began to consolidate IBG LLC’s financial results into its financial statements. When we use the terms ‘‘we,’’ ‘‘us,’’ and ‘‘our,’’ we mean IBG LLC and its subsidiaries for periods prior to the IPO, and IBG, Inc. and its subsidiaries (including IBG LLC) for periods from and after the IPO. Unless otherwise indicated, the term ‘‘common stock’’ refers to the Class A common stock of IBG, Inc. We are a successor to the market making business founded by our Chairman and Chief Executive Officer, Mr. Thomas Peterffy, on the floor of the American Stock Exchange in 1977. Since our inception, we have focused on developing proprietary software to automate broker-dealer functions. During that time, we have been a pioneer in developing and applying technology as a financial intermediary to increase liquidity and transparency in the capital markets in which we operate. The proliferation of electronic exchanges in the last 25 years has provided us with the opportunity to integrate our software with an increasing number of exchanges and market centers into one automatically functioning, computerized platform that requires minimal human intervention. Over three decades of developing our automated trading platforms and our automation of many middle and back office functions have allowed us to become one of the lowest cost providers of broker-dealer services and significantly increase the volume of trades we handle. Our activities are divided into two principal business segments: (1) electronic brokerage and (2) market making: (cid:129) As a direct market access broker, we serve the customers of both traditional brokers and prime brokers. We provide our customers with an advanced order management, trade execution and portfolio management platform at a very low cost. Our customers can simultaneously access many financial markets worldwide and trade across multiple asset classes (stocks, options, futures, foreign exchange (‘‘forex’’), bonds and mutual funds) denominated in 23 different currencies, on one screen, from a single account based in any major currency. Our large financial advisor and broker-dealer customers may ‘‘white brand’’ our trading interface (i.e., make our trading interface available to their customers without referencing our name), or they can select from among our modular functionalities, such as order routing, trade reporting or clearing on specific products or exchanges where they may not have up-to-date technology to offer their customers a comprehensive, global range of services and products. The emerging 2 complexity of multiple market centers provided us with the opportunity of building and continuously adapting our order routing software to secure excellent execution prices for our customers. This has become our major focus. (cid:129) As a market maker, we provide continuous bid and offer quotations on over one million securities and futures products listed on electronic exchanges around the world. Our quotes are driven by proprietary mathematical models that assimilate market data and reevaluate our outstanding quotes each second. Unlike firms that trade over-the-counter (‘‘OTC’’) derivative products, our business creates liquidity and transparency on electronic exchanges. In the past several years our market making business has suffered from competitive pressures and along with the rapid increase of our electronic brokerage business, its significance has diminished. Our electronic brokerage and market making businesses are complementary. Both benefit from our combined scale and volume, as well as from our proprietary technology. Our brokerage customers benefit from the technology and market structure expertise developed in our market making business. The expense of developing and maintaining our unique technology, clearing, settlement, banking and regulatory structure required by any specific exchange or market center is shared by both of our businesses. These economies, in turn, enable us to provide lower transaction costs to our customers than our competitors. In addition, we believe we gain a competitive advantage by applying the software features we have developed for a specific product or market to newly-introduced products and markets over others who may have less automated facilities in one or both of our businesses or who operate only in a subset of the exchanges and market centers on which we operate. Our trading system contains unique architectural aspects that, together with our massive trading volume in markets worldwide, may impose a significant barrier to entry for firms wishing to compete in our specific businesses and permit us to compete favorably against our competitors. In addition, many of our regulatory and compliance functions have been built into our integrated market making, order routing and custodial systems. Our internet address is www.interactivebrokers.com and the investor relations section of our web site is located at www.interactivebrokers.com/ir. We make available free of charge, on or through the investor relations section of our web site, this Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, related Interactive Data exhibits, Current Reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as well as proxy statements, registrations statements and prospectus supplements, as soon as reasonably practicable after we electronically file such material with, or furnish it to, the U.S. Securities and Exchange Commission (‘‘SEC’’). Also posted on our web site are our Bylaws, our Amended and Restated Certificate of Incorporation, charters for the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee of our board of directors, our Accounting Matters Complaint Policy, our Whistle Blower Hotline, our Corporate Governance Guidelines and our Code of Business Conduct and Ethics governing our directors, officers and employees. Within the time periods required by SEC and the NASDAQ Stock Market (‘‘NASDAQ’’), we will post on our web site any amendment to the Code of Business Conduct and Ethics and any waiver applicable to any executive officer, director or senior financial officer. In addition, our web site includes information concerning purchases and sales of our equity securities by our executive officers and directors, as well as disclosure relating to certain non-GAAP financial measures (as defined in Regulation G) promulgated under the Securities Act of 1933, as amended (the ‘‘Securities Act’’) and the Securities Exchange Act of 1934, as amended (the ‘‘Exchange Act’’) that we may make public orally, telephonically, by webcast, by broadcast or by similar means from time to time.

The remaining approximately 84.3% of IBG LLC membership interests are held by IBG Holdings LLC (‘‘Holdings’’), a holding company that is owned by our founder, Chairman and Chief Executive Officer, Mr. Thomas Peterffy and his affiliates, management and other employees of IBG LLC, and certain other members. The IBG LLC membership interests held by Holdings will be subject to purchase by us over time in connection with 4 offerings by us of shares of our common stock. The below table shows the amount of IBG LLC membership interests held by IBG, Inc. and Holdings as of December 31, 2015. Ownership % . . . . . . . . . . . . . . . . . . . . . . Membership interests . . . . . . . . . . . . . . . . . 15.7% 84.3% 100.0% 63,991,705 343,040,504 407,032,209 Public Holdings Total Purchases of IBG LLC membership interests, held by Holdings, by the Company are governed by the exchange agreement among us, IBG LLC, Holdings and the historical members of IBG LLC, (the ‘‘Exchange Agreement’’), a copy of which was filed as an exhibit to our Quarterly Report on Form 10-Q for the quarter ended September 30, 2009 and filed with the SEC on November 9, 2009. The Exchange Agreement, as amended June 6, 2012, provides that the Company may facilitate the redemption by Holdings of interests held by its members through the issuance of shares of common stock through a public offering in exchange for the interests in IBG LLC being redeemed by Holdings. The June 6, 2012 amendment (the ‘‘Amendment’’), which was filed as an exhibit to our Form 8-K filed with the SEC on June 6, 2012, eliminated from the Exchange Agreement an alternative funding method, which provided that upon approval by the board of directors and by agreement of the Company, IBG LLC and Holdings, redemptions could be made in cash. At the time of the Company’s IPO in 2007, three hundred sixty (360) million shares of authorized common stock were reserved for future sales and redemptions. From 2008 through 2010, Holdings redeemed 5,013,259 IBG LLC shares for a total of $114 million, which redemptions were funded using cash on hand at IBG LLC. Upon cash redemption these IBG LLC shares were retired. In June 2011, with the consent of Holdings and the Company (on its own behalf and acting as the sole managing member of IBG LLC), IBG LLC agreed to redeem certain membership interests from Holdings through the sale of common stock and to distribute the proceeds of such sale to the beneficial owners of such membership interests. On August 4, 2011, the Company filed a ‘‘shelf’’ Registration Statement on Form S-3 (File Number 333-176053) with the SEC for the issuance of additional shares in connection with Holdings requesting redemption of a portion of its member interests in IBG LLC. Under this shelf registration statement, in 2011, the Company issued 1,983,624 shares of common stock (with a fair value of $29 million) to Holdings in exchange for an equivalent number of shares of member interests in IBG LLC. On November 12, 2013, the Company filed a ‘‘shelf’’ Registration Statement on Form S-3 (File Number 333-192275) with the SEC for the issuance of additional shares in connection with Holdings requesting redemption of a portion of its member interests in IBG LLC. Under this shelf registration statement, from 2013 through 2015, the Company issued 9,063,671 shares of common stock (with a fair value of $277 million) to Holdings in exchange for an equivalent number of shares of member interests in IBG LLC. 5 Segment Operating Results Electronic Brokerage . . . . . . . .

(2) The corporate segment includes corporate related activities, inter-segment eliminations and net gains and losses on positions held as part of our overall currency diversification strategy. Financial information concerning our business segments for each of 2015, 2014 and 2013 is set forth in ‘‘Management’s Discussion and Analysis of Financial Condition and Results of Operations,’’ and the consolidated financial statements and the notes thereto, which are in Part II, Items 7 and 8 of this Annual Report on Form 10-K. Electronic Brokerage—Interactive Brokers Electronic brokerage represented 79% of net revenues and 80% of income before income taxes from electronic brokerage and market making combined during 2015. We conduct our electronic brokerage business through our Interactive Brokers (‘‘IB’’) subsidiaries. As an electronic broker, we execute, clear and settle trades globally for both institutional and individual customers. Capitalizing on the technology originally developed for our market making business, IB’s systems provide our customers with the capability to monitor multiple markets around the world simultaneously and to execute trades electronically in these markets at a low cost in multiple products and currencies from a single trading account. 6 Since launching this business in 1993, we have grown to approximately 331 thousand institutional and individual brokerage customers. We provide our customers with what we believe to be one of the most effective and efficient electronic brokerage platforms in the industry. The following are key highlights of our electronic brokerage business: (cid:129) Low Costs—We provide our customers with among the industry’s lowest overall transaction costs in two ways. First, we offer among the lowest execution, commission and financing costs in the industry. Second, our customers benefit from our advanced routing of orders designed to achieve the best available trade price. In order to illustrate this advantage, we publish monthly brokerage metrics including our customers’ average net trade cost for Reg.-NMS stocks. In 2015, customers’ total all-in cost of executing and clearing U.S. Reg.-NMS stocks through IB, including brokerage commissions, regulatory and exchange fees and market impact, was 0.8 basis points of trade money, as measured against a daily volume-weighted average price (‘‘VWAP’’) benchmark. (cid:129) Automated Risk Controls—Throughout the trading day, we calculate margin requirements for each of our customers on a real-time basis across all product classes (stocks, options, futures, bonds, forex, and mutual funds) and across all currencies. Our customers are alerted to approaching margin violations and if a customer’s equity falls below what is required to support that customer’s margin, we attempt to automatically liquidate positions on a real-time basis to bring the customer’s account into margin compliance. This is done to protect IB, as well as the customer, from excessive losses. (cid:129) IB Universal AccountSM—From a single point of entry in one IB Universal AccountSM our customers are able to trade products denominated in 23 currencies, across multiple classes of tradable, exchange-listed products, including stocks, options, futures, bonds, forex and mutual funds traded on more than 100 exchanges and market centers and in 24 countries around the world seamlessly. (cid:129) IB SmartRoutingSM—Our customers benefit from our advanced order routing technology. IB SmartRoutingSM retains control of the customer’s order, continuously searches for the best available price and, unlike most other routers, dynamically routes and re-routes all or parts of a customer’s order to achieve optimal execution and among the lowest execution and commission costs in the industry. To highlight the quality of our price executions, we publish on our website independent measurements performed by a third party provider of transaction analysis to illustrate IB’s net price improvement versus the industry. We also offer Transaction Cost Analysis reporting to allow customers to track execution performance by criteria including trade date, trade price, underlying and exchange. (cid:129) Flexible and Customizable System—Our platform is designed to provide an efficient customer experience, beginning with a highly automated account opening process and ending with a fast trade execution, with real-time position monitoring. Our sophisticated interface provides interactive real-time views of account balances, positions, profits or losses, buying power and ‘‘what-if’’ scenarios to enable our customers to more easily make informed investment decisions and trade efficiently. Our system is configured to remember the user’s preferences and is specifically designed for multi-screen systems. When away from their main workstations, customers are able to access their accounts through our IB WebTraderSM or MobileTraderSM interfaces. (cid:129) Interactive AnalyticsSM and IB Options AnalyticsSM—We offer our customers state-of-the-art tools, which include a customizable trading platform, advanced analytic tools and over 60 sophisticated order types and algorithms. We also provide a real-time option analytics window which displays values that reflect the rate of change of an option’s price with respect to a unit change in each of a number of risk dimensions. 7 (cid:129) Probability LabSM (Patent Pending)—The Probability Lab provides clients with an intuitive, visual method to analyze market participants’ future stock price forecasts based on current option prices. This tool compares a client’s stock price forecast versus that of the market, and scans the entire option universe for the highest Sharpe ratio multi-leg option strategies that take advantage of the client’s forecast. (cid:129) IB Risk NavigatorSM—We offer free to all customers our real-time market risk management platform that unifies exposure across multiple asset classes around the globe. The system is capable of identifying overexposure to risk by starting at the portfolio level and drilling down into successively greater detail within multiple report views. Report data is updated every ten seconds or upon changes to portfolio composition. Predefined reports allow the summarization of a portfolio from different risk perspectives, and allow views of Exposure, Value at Risk (‘‘VaR’’), Delta, Gamma, Vega and Theta, profit and loss and position quantity measures for the different portfolio views. The system also offers the customer the ability to modify positions through ‘‘what-if’’ scenarios that show hypothetical changes to the risk summary. (cid:129) White Branding—Our large financial advisor and broker-dealer customers may ‘‘white brand’’ our trading interface, account management and reports with their firm’s identity. Broker-dealer clients can also select from among our modular functionalities, such as order routing, trade reporting or clearing, on specific products or exchanges where they may not have up-to-date technology, in order to offer to their customers a complete global range of services and products. (cid:129) Securities Financing Services—We offer a suite of automated Stock Borrow and Lending tools, including our depth of availability, transparent rates, global reach and dedicated service representatives. Our Stock Yield Enhancement Program allows our customers to lend their fully-paid stock shares to us in exchange for cash collateral. In turn, we lend these stocks in exchange for collateral and earn stock lending fees. Our customers receive generally 50% of the fees collected from lending their stocks. This allows customers holding fully-paid long stock positions to enhance their returns. (cid:129) Investors’ Marketplace—The Investors’ Marketplace is an expansion of our Money Manager Marketplace and our Hedge Fund Capital Introduction program. This program is the first electronic meeting place that brings together individual investors, financial advisors, money managers, fund managers, research analysts, technology providers, business developers and administrators, allowing them to interact to form connections and conduct business. (cid:129) Trade Desk—We offer broker-assisted trading through our block trade desk, which is ideal when customers are away from their computer, or if they just want another set of eyes watching their orders and updating them on market changes. (cid:129) Model Portfolios—Model Portfolios offer advisors an efficient and time-saving approach to investing client assets. They allow advisors to create groupings of financial instruments based on specific investment themes, and then invest client funds into these models. (cid:129) Portfolio Builder—Portfolio Builder allows our customers to set up an investment strategy based on research and rankings from top buy-side providers and fundamental data; use filters to define the universe of equities that will comprise their strategy and back-test their strategy using up to three years of historical performance; work in hypothetical mode to adjust the strategy until the historical performance meets their standards; and with the click of a button let the system create the orders to invest in a strategy and track its performance in their portfolio. 8 (cid:129) Registered Investment Advisors (‘‘RIA’’) Compliance Center—RIA Compliance Center provides information to assist advisors with registration and compliance obligations. This functionality includes an overview for advisor’s registration and compliance obligations; a series of spotlights, providing an in-depth look at compliance issues of interest to investment advisors; links to key regulatory websites; information on preferred providers for RIAs; and sample documents, such as client agreements and disclosers, along with other beneficial information. (cid:129) Covestor—Covestor recruits registered financial advisors, vets them, analyzes their investment track records, and groups them by their risk profile. Retail investors who are interested in having their individual accounts robo-traded are grouped by their risk return preferences, and members of matching groups are electronically introduced to each other. Retail investors can assign their accounts to be traded by one or more advisors. We are able to provide our customers with high-speed trade execution at low commission rates, in large part because we utilize the backbone technology developed for our market making operations. As a result of our advanced electronic brokerage platform, we attract sophisticated and active investors. No single customer represented more than 1% of our commissions and execution fees in 2015. Market Making—Timber Hill Market making represented 21% of net revenues and 20% of income before income taxes from electronic brokerage and market making combined during 2015. We conduct our market making business primarily through our Timber Hill (‘‘TH’’) subsidiaries. As one of the largest market makers on many of the world’s leading electronic exchanges, we provide liquidity by offering competitively tight bid/offer spreads over a broad base of over one million tradable, exchange-listed products, including equity derivative products, equity index derivative products, equity securities and futures. As principal, we commit our own capital and derive revenues or incur losses from the difference between the price paid when securities are bought and the price received when those securities are sold. Historically, our profits have been principally a function of transaction volume and price volatility of electronic exchange-traded products rather than the direction of price movements. Other factors, including the ratio of actual to implied volatility and shifts in foreign currency exchange rates, can also have a meaningful impact on our results, as described further in ‘‘Business Environment’’ in Part II, Item 7 of this Annual Report on Form 10-K. Our strategy is to calculate quotes at which supply and demand for a particular security are likely to be in balance a few seconds ahead of the market and execute small trades at tiny but favorable differentials. Because we provide continuous bid and offer quotations and we are continuously both buying and selling quoted securities, we may have either a long or a short position in a particular product at a given point in time. As a matter of practice, we will generally not take portfolio positions in either the broad market or the financial instruments of specific issuers in anticipation that prices will either rise or fall. Our entire portfolio is evaluated each second and continuously rebalanced throughout the trading day, thus minimizing the risk of our portfolio at all times. This real-time rebalancing of our portfolio, together with our real-time proprietary risk management system, enables us to curtail risk and to be profitable in both up-market and down-market scenarios. Our quotes are based on our proprietary model rather than customer order flow, and we believe that this approach provides us with a competitive advantage. We are a market leader in exchange-traded equity options and equity-index options and futures. Together with our electronic brokerage customers, in 2015 we accounted for approximately 7.8% of exchange-listed equity options traded worldwide according to data received from exchanges worldwide. Our ability to make markets in such a large number of exchanges and market centers simultaneously around the world is one of our core strengths and has contributed to the large volumes in our market 9 making business. We engage in market making operations in North and South America, Europe and in the Asia/Pacific regions as described below. North and South American Market Making Activities. Our U.S. market making activities are conducted through Timber Hill LLC (‘‘TH LLC’’), a SEC-registered securities broker-dealer that conducts market making in equity derivative products, equity index derivative products and equity securities. Since its inception in 1982, TH LLC has grown to become one of the largest listed options market makers in the U.S. As of December 31, 2015, TH LLC held specialist, primary market maker or lead market maker designations in options on approximately 1,010 underlying securities listed in the U.S. TH LLC is a member of the Boston Options Exchange, BATS exchange, Chicago Board Options Exchange, Chicago Mercantile Exchange, Chicago Board of Trade, International Securities Exchange, NYSE AMEX Options Exchange, NYSE Arca, OneChicago, NASDAQ OMX’s PHLX and NOM option markets and the New York Mercantile Exchange. TH LLC also conducts market making activities in Mexico at the MEXDER and the Mexican Stock Exchange; and in Brazil at BM&F BOVESPA S.A. We conduct market making activities in Canada through our Canadian subsidiary, Timber Hill Canada Company (‘‘THC’’) at the Toronto Stock Exchange and Montreal Exchange. In addition, we participate in stock trading at various notable Electronic Communications Networks (‘‘ECNs’’) in both the U.S. and Canada. European, Asian, and Australian Market Making Activities. Our European, Asian, and Australian market making subsidiaries, the largest of which is Timber Hill Europe AG (‘‘THE’’), conduct operations in 19 countries, comprising the major securities markets in these regions. We began our market making operations in Europe in 1990. In Germany and Switzerland, we have been among the largest equity options market makers in terms of volume on Eurex, one of the world’s largest futures and options exchanges, which is jointly operated by Deutsche B¨orse AG and SIX Swiss Exchange. We have also been active in trading German stocks and warrants as a member of XETRA, the German electronic stock trading system, and the Frankfurt and Stuttgart stock exchanges; and in Switzerland as a member of the SIX Swiss Exchange. Our other European operations are conducted on the London Stock Exchange; the Weiner B¨orse AG; the Euronext exchanges in Amsterdam, Paris, Brussels and London; NASDAQ OMX Nordic exchanges in Sweden, Finland and Denmark; the MEFF and Bolsa de Valores Madrid in Spain; the IDEM and Borsa Valori de Milano in Milan; and the ¨OTOB in Vienna. Since 1995, we have conducted market making operations in Hong Kong. Our Hong Kong subsidiary, Interactive Brokers Hong Kong Limited (formerly Timber Hill Securities Hong Kong Ltd), is a member of the cash and derivatives markets of the Hong Kong Exchanges. Since 1997, we have conducted operations in Australia. Our Australian subsidiary, Timber Hill Australia Pty Ltd (‘‘THA’’), is a member of the Australian Stock Exchange, and routes orders for its trading on ASX 24 through its affiliate, Interactive Brokers LLC (‘‘IB LLC’’). We commenced trading in Japan in 2002, Korea and Singapore in 2004 and Taiwan in 2007. In 2008, we began our market making operation and, subsequently, brokerage activities in India through our subsidiary, Interactive Brokers (India) Private Limited (‘‘IBI’’), which is a member of the National Stock Exchange of India and the Bombay Stock Exchange. Most of the above trading activities take place on exchanges and all securities and commodities that we trade are cleared by exchange owned or authorized clearing houses. Recently, the emergence of high frequency traders (‘‘HFTs’’) and others who compete with us but do not regularly provide liquidity have put our market making operations under pressure and the relative significance of market making to our business has diminished. 10 Technology Our proprietary technology is the key to our success. We built our business on the belief that a fully computerized market making system that could integrate pricing and risk exposure information quickly and continuously would enable us to make markets profitably in many different financial instruments simultaneously. We believe that integrating our system with electronic exchanges and market centers results in transparency, liquidity and efficiencies of scale. Together with the IB SmartRoutingSM system and our low commissions, these features reduce overall transaction costs to our customers and, in turn, increases our transaction volume and profits. Over the past 38 years, we have developed an integrated trading system and communications network and have positioned our company as an efficient conduit for the global flow of risk capital across asset and product classes on electronic exchanges around the world, permitting us to have one of the lowest cost structures in the industry. We believe that developing, maintaining and continuing to enhance our proprietary technology provides us and our customers with the competitive advantage of being able to adapt quickly to the changing environment of our industry and to take advantage of opportunities presented by new exchanges, products or regulatory changes before our competitors. The quotes that we provide as market makers are driven by proprietary mathematical models that assimilate market data and re-evaluate our outstanding quotes each second. Because our technology infrastructure enables us to process large volumes of pricing and risk exposure information rapidly, we are able to make markets profitably in securities with relatively low spreads between bid and offer prices. As market makers, we must ensure that our interfaces connect effectively and efficiently with each exchange and market center where we make markets and that they are in complete conformity with all the applicable rules of each local venue. Utilizing up-to-date computer and telecommunications systems, we transmit continually updated pricing information directly to exchange computer devices and receive trade and quote information for immediate processing by our systems. As a result, we are able to maintain more effective control over our exposure to price and volatility movements on a real-time basis than many of our competitors. This control is important, not only because our system must process, clear and settle several hundred thousand market maker trades per day with a minimal number of errors, but also because the system monitors and manages the risk on the entire portfolio, which generally consists of more than ten million open contracts distributed among many hundreds of thousands of different products. Using our system, which we believe affords an optimal interplay of decentralized trading activity and centralized risk management, we quote markets in over one million securities and futures products traded around the world. In our electronic brokerage business, our proprietary technology infrastructure enables us to provide our customers with the ability to execute trades at among the lowest commission costs in the industry. Additionally, our customers benefit from real-time systems optimization for our market making business. Customer trades are both automatically captured and reported in real time in our system. Our customers trade on more than 100 exchanges and market centers in 24 countries around the world. All of these exchanges are partially or fully electronic, meaning that a customer can buy or sell a product traded on that exchange via an electronic link from his or her computer terminal through our system to the exchange. We offer our products and services through a global communications network that is designed to provide secure, reliable and timely access to the most current market information. We provide our customers with a variety of means to connect to our brokerage systems, including dedicated point-to-point data lines, virtual private networks and the Internet. Specifically, our customers receive worldwide electronic access connectivity through our Trader Workstation (our real-time Java-based trading platform), our proprietary Application Programming Interface (‘‘API’’), and/or industry standard Financial Information Exchange (‘‘FIX’’) connectivity. Customers who want a professional quality trading application with a sophisticated user interface utilize our Trader Workstation which can be accessed through a desktop or variety of mobile devices. Customers interested in developing program trading applications in MS-Excel, Java, Visual Basic or 11 C++ utilize our API. Large institutions with FIX infrastructure prefer to use our FIX solution for seamless integration of their existing order gathering and reporting applications. While many brokerages, including some online brokerages, rely on manual procedures to execute many day-to-day functions, IB employs proprietary technology to automate, or otherwise facilitate, many of the following functions: (cid:129) account opening process; (cid:129) order routing and best execution; (cid:129) seamless trading across all types of securities and currencies around the world from one account; (cid:129) order types and analytical tools offered to customers; (cid:129) delivery of customer information, such as confirmations, customizable real-time account statements and audit trails; (cid:129) customer service; and (cid:129) risk management through automated real-time credit management of all new orders and margin monitoring. Research and Development One of our core strengths is our expertise in the rapid development and deployment of automated technology for the financial markets. Our core software technology is developed internally, and we do not generally rely on outside vendors for software development or maintenance. To achieve optimal performance from our systems, we are continuously rewriting and upgrading our software. Use of the best available technology not only improves our performance but also helps us attract and retain talented developers. Our software development costs are low because the employees who oversee the development of the software are the same employees who design the application, evaluate its performance, and participate along with our quality assurance professionals in our robust quality assurance testing procedures. The involvement of our developers in each of these processes enables us to add features and further refine our software rapidly. Our internally-developed, fully integrated trading and risk management systems are unique and transact across all product classes on more than 100 electronic exchanges and market centers and in 23 currencies around the world. These systems have the flexibility to assimilate new exchanges and new product classes without compromising transaction speed or fault tolerance. Fault tolerance, or the ability to maintain system performance despite exchange malfunctions or hardware failures, is crucial to successful market making and ensuring best executions for brokerage customers. Our systems are designed to detect exchange malfunctions and quickly take corrective actions by re-routing pending orders. Our company is technology-focused, and our management team is hands-on and technology-savvy. Most members of the management team write detailed program specifications for new applications. The development queue is prioritized and highly disciplined. Progress on programming initiatives is generally tracked on a weekly basis by a steering committee consisting of senior executives. This enables us to prioritize key initiatives and achieve rapid results. All new business starts as a software development project. We generally do not engage in any business that we cannot automate and incorporate into our platform prior to entering into the business. The rapid software development and deployment cycle is achieved by our ability to leverage a highly integrated, object oriented development environment. The software code is modular, with each object providing a specific function and being reusable in multiple applications. New software releases are tracked and tested with proprietary automated testing tools. We are not hindered by disparate and often limiting legacy systems assembled through acquisitions. Virtually all of our software has been developed and maintained with a unified purpose. 12 For over 37 years, we have built and continuously refined our automated and integrated, real-time systems for world-wide trading, risk management, clearing and cash management, among others. We have also assembled a proprietary connectivity network between us and exchanges around the world. Efficiency and speed in performing prescribed functions are always crucial requirements for our systems. As a result, our trading systems are able to assimilate market data, recalculate and distribute streaming quotes for tradable products in all product classes each second. Risk Management Activities The core of our risk management philosophy is the utilization of our fully integrated computer systems to perform critical, risk-management activities on a real-time basis. In our market making business, our real-time integrated risk management system seeks to ensure that our overall positions are continuously hedged at all times, curtailing risk. In our electronic brokerage business, integrated risk management seeks to ensure that each customer’s positions are continuously credit checked and brought into compliance if equity falls short of margin requirements, curtailing bad debt losses. We actively manage our global currency exposure on a continuous basis by maintaining our equity in a basket of currencies we call the GLOBAL. In 2011, we expanded the composition of the GLOBAL from six to 16 currencies to better reflect the expanding breadth of our businesses around the world. We define the GLOBAL as consisting of fractions of a U.S. dollar, Euro, Japanese yen, British pound, Canadian dollar, Australian dollar, Swiss franc, Hong Kong dollar, Swedish krona, Mexican peso, Danish krone, Norwegian krone, South Korean won, Brazilian real, Indian rupee and Singapore dollar. We currently transact business and are required to manage balances in each of these 16 currencies. The currencies comprising the GLOBAL and their relative proportions can change over time. Additional information regarding our currency diversification strategy is set forth in ‘‘Quantitative and Qualitative Disclosures About Market Risk’’ in Part II, Item 7A of this Annual Report on Form 10-K. Electronic Brokerage We calculate margin requirements for each of our customers on a real-time basis across all product classes (stocks, options, futures, forex, bonds and mutual funds) and across all currencies. Recognizing that our customers are experienced investors, we expect our customers to manage their positions proactively and we provide tools to facilitate our customers’ position management. However, if a customer’s equity falls below what is required to support that customer’s margin, we will automatically liquidate positions on a real-time basis to bring the customer’s account into margin compliance. We do this to protect us, as well as the customer, from excessive losses. These systems further contribute to our low-cost structure. The entire credit management process is completely automated. As a safeguard, all liquidations are displayed on custom built liquidation monitoring screens that are part of the toolset our technical staff uses to monitor performance of our systems at all times the markets around the world are open. In the event our systems absorb erroneous market data from exchanges, which prompts liquidations, risk specialists on our technical staff have the capability to halt liquidations that meet specific criteria. The liquidation halt function is highly restricted. Our customer interface includes color coding on the account screen and pop-up warning messages to notify customers that they are approaching their margin limits. This feature allows customers to take action, such as entering margin reducing trades, to avoid having us liquidate their positions. These tools and real-time margining allow our customers to understand their trading risk at any moment of the day and help us maintain low commissions. 13 Market Making We employ certain hedging and risk management techniques to protect us from a severe market dislocation. Our risk management policies are developed and implemented by our Chairman and our steering committee, which is comprised of senior executives of our various companies. Our strategy is to calculate quotes a few seconds ahead of the market and execute small trades at a tiny but favorable differential as a result. This strategy is made possible by our proprietary pricing model, which evaluates and monitors the risks inherent in our portfolio, assimilates market data and reevaluates the outstanding quotes in our portfolio each second. Our model automatically rebalances our positions throughout each trading day to manage risk exposures both on our options and futures positions and the underlying securities, and it will price the increased risk that a position would add to the overall portfolio into the bid and offer prices we post. Under risk management policies implemented and monitored primarily through our computer systems, reports to management, including risk profiles, profit and loss analysis and trading performance, are prepared on a real-time basis as well as daily and periodical bases. Although our market making is completely automated, the trading process and our risk are monitored by a team of individuals who, in real-time, observe various risk parameters of our consolidated positions. Our assets and liabilities are marked-to-market daily for financial reporting purposes and re-valued continuously throughout the trading day for risk management and asset/liability management purposes. We trade primarily the options on stocks (and individual stocks) whose underlying equity market capitalization is greater than $500 million. Throughout the trading day we produce online, real-time profit and loss, risk evaluation, activity and other management reports. Our systems compile a daily balance sheet and income statements for our accounting department to review and to reconcile to our trading system results and data from external sources. The adaptability of our portfolio risk management system and our trading methods allow us to trade a large number of financial instruments across many markets using the same risk management system and similar trading methods. Operational Controls We have automated the full cycle of controls surrounding the market making and brokerage businesses. Key automated controls include the following: (cid:129) Our technical operations section continuously monitors our network and the proper functioning of each of our nodes (exchanges, internet service providers (‘‘ISPs’’), leased customer lines and our own data centers) around the world. (cid:129) Our real-time credit manager software provides pre and post-execution controls by: (cid:129) testing every customer order to ensure that the customer’s account holds enough equity to support the execution of the order, rejecting the order if equity is insufficient or directing the order to an execution destination without delay if equity is sufficient; and (cid:129) continuously updating a customer account’s equity and margin requirements and, if the account’s equity falls below its minimum margin requirements, automatically issuing liquidating orders in a smart sequence designed to minimize the impact on account equity. (cid:129) Our market making system continuously evaluates over one million securities and futures products in which we provide bid and offer quotes and changes our bids and offers in such a way as to maintain an overall hedge and a low-risk profile. The speed of communicating with exchanges and market centers is maximized through continuous software and network engineering innovation, thereby allowing us to achieve real-time controls over market exposure. 14 (cid:129) Our clearing system captures trades in real-time and performs automated reconciliation of trades and positions, corporate action processing, customer account transfer, options exercise, securities lending and inventory management, allowing us to effectively manage operational risk. (cid:129) Our accounting system operates with automated data feeds from clearing and banking systems, allowing us to produce financial statements for all parts of our business every day by mid-day on the day following trade date. (cid:129) Software developed to interface with the accounting and market making systems performs daily profit and loss reconciliations, which provide tight financial controls over market making functions. Transaction Processing Our transaction processing is automated over the full life cycle of a trade. Our market making software generates and disseminates to exchanges and market centers continuous bid and offer quotes on over one million tradable, exchange-listed products. Our fully automated smart router system searches for the best possible combination of prices available at the time a customer order is placed and immediately seeks to execute that order electronically or send it where the order has the highest possibility of execution at the best price. At the moment a trade is executed, our systems capture and deliver this information back to the source, either the market making system or via the brokerage system to the customer, in most cases within a fraction of a second. Simultaneously, the trade record is written into our clearing system, where it flows through a chain of control accounts that allow us to reconcile trades, positions and money until the final settlement occurs. Our integrated software tracks other important activities, such as dividends, corporate actions, options exercises, securities lending, margining, risk management and funds receipt and disbursement. IB SmartRoutingSM IB SmartRoutingSM searches for the best destination price in view of the displayed prices, sizes and accumulated statistical information about the behavior of market centers at the time an order is placed, and IB SmartRoutingSM immediately seeks to execute that order electronically. Unlike other smart routers, IB SmartRoutingSM never relinquishes control of the order, and constantly searches for the best price. It continuously evaluates fast-changing market conditions and dynamically re-routes all or parts of the order seeking to achieve optimal execution. IB SmartRoutingSM represents each leg of a spread order independently and enters each leg at the best possible venue. IB SmartRouting AutorecoverySM re-routes a customer’s U.S. options order in the case of an exchange malfunction, and we undertake the risk of double executions. In addition, IB SmartRoutingSM checks each new order to see if it could be executed against any of its pending orders. As the system gains more users, this feature becomes more important for customers in a world of multiple exchanges, market centers and penny priced orders because it increases the possibility of best executions for our customers ahead of customers of other brokers. As a result of this feature, our customers have a greater chance of executing limit orders and can do so sooner than those who use other routers. Clearing and Margining Our activities in the U.S. are entirely self-cleared. We are a full clearing member of OCC (the Options Clearing Corporation), the Chicago Mercantile Exchange Clearing House (‘‘CMECH’’), The Depository Trust & Clearing Corporation and ICE Clear U.S. 15 Due to our large positions in broad based index products, we benefit from the cross-margin system maintained by OCC and CMECH. For example, if we hold a position in an OCC cleared product and have an offsetting position in a CMECH cleared product, the cross-margin computation takes both positions into account, thereby reducing the overall margin requirement. The reduced margin benefit proves especially useful during times of market stress, such as on days with large price movements when intra-day margin calls may be reduced or eliminated by the cross-margin calculation. In addition, we are fully or partially self-cleared in Canada, Great Britain, Switzerland, France, Germany, Belgium, Austria, the Netherlands, Norway, Sweden, Denmark, Finland, India and Hong Kong. Customers We established our electronic brokerage subsidiary, IB LLC, in 1993 to enhance the use of our global network of trading interfaces, exchange and clearinghouse memberships, and regulatory registrations assembled over the prior 16 years to serve our market making business. We realized that electronic access to market centers worldwide through our network could easily be utilized by the very same floor traders and trading desk professionals who, in the coming years, would be displaced by the conversion of exchanges from open outcry to electronic systems. We currently service approximately 331 thousand cleared customer accounts. Our customers reside in over 190 countries around the world. Our target customer is one that requires the latest in trading technology, worldwide access and expects low overall transaction costs. Our customers are mainly comprised of ‘‘self-service’’ individuals, former floor traders, trading desk professionals, electronic retail brokers, financial advisors who are comfortable with technology, banks that require global access, and hedge funds. Our customers fall into three groups based on services provided: cleared customers, trade execution customers, and wholesale customers. By offering portfolio margining and other institutional services, we have been able to persuade many of our trade execution hedge fund customers to utilize our cleared business solution, which benefits the hedge funds in terms of cost savings. Many prime brokers once offered increased leverage over Regulation T credit limitations and NYSE margin requirements through offshore entities and joint back office arrangements. Following the market turmoil of late 2008 and the resulting tightening of credit, we observed competition in this area diminish. Through portfolio margining, we are able to offer similar leverage with lower margin requirements that reflect the reduced risk of a hedged portfolio. (cid:129) Cleared Customers: We provide trade execution and clearing services to our cleared customers who are generally attracted to our low commissions, low financing rates, high interest paid and best price execution. From small market making groups and individual market makers, our cleared customer base has expanded over the years to include institutional and individual traders and investors, financial advisors and introducing brokers. (cid:129) Trade Execution Customers: We offer trade execution for customers who choose to clear with another prime broker or a custodian bank; these customers are able to take advantage of our low commissions for trade execution as well as our best price execution. (cid:129) Wholesale Customers: Our wholesale customers, which include some of the largest banks and retail electronic brokers, are generally self-clearing. These customers count on us for our superior options and option/stock combination trade routing and execution and our ability to assist them in satisfying their regulatory requirements to provide best execution to their customers. 16 Our non-cleared customers include large online brokers and increasing numbers of the proprietary and customer trading units of U.S., Canadian and European commercial banks. These customers are attracted by our IB SmartRoutingSM technology as well as our direct access to stock, options, futures, forex and bond markets worldwide. Our customers receive worldwide electronic access connectivity in one of three ways: the Trader Workstation via desktop or mobile device, our proprietary API, and/or industry standard FIX connectivity. Employees and Culture We take pride in our technology-focused company culture and embrace it as one of our fundamental strengths. We remain committed to improving our technology and we try to minimize corporate hierarchy to facilitate efficient communication among employees. We have assembled what we believe is a highly talented group of employees. As we grow, we expect to continue to provide significant rewards for our employees who provide substantial value to us and the world’s financial markets. As of December 31, 2015, we had 1,087 employees, of which 1,037 own shares of the Company either vested, unvested or both, all of whom were employed on a full-time basis. None of our employees are covered by collective bargaining agreements. We believe that our relations with our employees are good. Competition Electronic Brokerage The market for electronic brokerage services is rapidly evolving and highly competitive. We believe that we fit neither within the definition of a traditional broker nor that of a traditional prime broker. Our primary competitors include offerings targeted to professional traders by large retail online brokers (such as TD Ameritrade’s thinkorswim, E*TRADE Pro business, and The Charles Schwab Corporation’s StreetSmart Edge and optionsXpress businesses) and the prime brokerage and electronic brokerage arms of major investment banks and brokers (such as Goldman Sachs’ Electronic Trading (GSET), and Morgan Stanley Electronic Trading (MSET)). We also encounter competition to a lesser extent from full commission brokerage firms including Bank of America Merrill Lynch and Morgan Stanley Smith Barney, as well as other financial institutions, most of which provide online brokerage services. The electronic brokerage businesses of many of our competitors are relatively insignificant in the totality of their firms’ business and many impose significant account equity minimums, which we do not. We provide access to a global range of products from a single IB Universal AccountSM and professional level executions and pricing, which positions us in competition with niche direct-access providers and prime brokers. In addition to offering low commissions and financing rates, we provide sophisticated order types and analytical tools that give a competitive edge to our customers. Market Making Historically, competition has come from registered market making firms which range from sole proprietors with very limited resources to large integrated broker-dealers. Today, our major competitors continue to be large broker-dealers, such as Goldman Sachs, Morgan Stanley, UBS, Citigroup, Bank of America Merrill Lynch, and niche players such as Citadel, Susquehanna, Virtu, Wolverine Trading, Group One Trading, Peak6 and Knight Capital Group. Some of our competitors in market making are larger than we are and have more captive order flow, although this is less true with respect to our narrow focus on options, futures and ETFs listed on electronic exchanges. 17 The competitive environment for market makers has evolved considerably in the past several years, most notably with the rise in HFTs, which transact significant trading volume on electronic exchanges by using complex algorithms and high speed execution software that analyzes market conditions. HFTs that are not registered market makers operate with fewer regulatory restrictions and are able to move more quickly and trade more cheaply. This issue is currently an area of focus amongst regulators who are examining the practices of HFTs and their impact on market structure. To compete successfully, we believe that we must have more sophisticated, versatile and robust software than our competitors. This is our primary focus, as contrasted with many of our competitors. With respect to these competitors, we maintain the advantage of having had much longer experience with the development and usage of proprietary electronic brokerage and market making systems. Market conditions that are difficult for other market participants often present us with the opportunities inherent in diminished competition. Our advantage is our expertise and decades of single-minded focus on developing our technology. This enables us to have a unique platform specializing strictly in electronic market making and brokerage. Regulation Our securities and derivatives businesses are extensively regulated by U.S. federal and state regulators, foreign regulatory agencies, numerous exchanges and self-regulatory organizations of which our subsidiaries are members. In the current era of heightened regulation of financial institutions, we expect to incur increasing compliance costs, along with the industry as a whole. Our approach has been to build many of our regulatory and compliance functions into our integrated market making, order routing and custodial systems. Overview As registered U.S. broker-dealers, IB LLC and TH LLC are subject to the rules and regulations of the Exchange Act, and as members of various exchanges, we are also subject to such exchanges’ rules and requirements. Additionally, IB LLC and TH LLC are subject to the Commodity Exchange Act and rules promulgated by the Commodity Futures Trading Commission (‘‘CFTC’’) and the various commodity exchanges of which they are members. We are also subject to the requirements of various self-regulatory organizations such as the Financial Industry Regulatory Authority (‘‘FINRA’’) and the National Futures Association (‘‘NFA’’). Our foreign affiliates are similarly regulated under the laws and institutional framework of the countries in which they operate. U.S. broker-dealers and futures commission merchants are subject to laws, rules and regulations that cover all aspects of the securities and derivatives business, including: (cid:129) sales methods; (cid:129) trade practices; (cid:129) use and safekeeping of customers’ funds and securities; (cid:129) capital structure; (cid:129) risk management; (cid:129) record-keeping; (cid:129) financing of customers’ purchases; and (cid:129) conduct of directors, officers and employees. In addition, the businesses that we may conduct are limited by our agreements with and our oversight by regulators. Participation in new business lines, including trading of new products or participation on new exchanges or in new countries often requires governmental and/or exchange approvals, which may take significant time and resources. As a result, we may be prevented from entering new businesses that may be profitable in a timely manner, or at all. 18 As certain of our subsidiaries are members of FINRA, we are subject to certain regulations regarding changes in control of our ownership. FINRA Rule 1017 generally provides that FINRA approval must be obtained in connection with any transaction resulting in a change in control of a member firm. The FINRA defines control as ownership of 25% or more of the firm’s equity by a single entity or person and would include a change in control of a parent company. As a result of these regulations, our future efforts to sell shares or raise additional capital may be delayed or prohibited by FINRA. Net Capital Rule The SEC, FINRA, CFTC and various other regulatory agencies within the U.S. have stringent rules and regulations with respect to the maintenance of specific levels of net capital by regulated entities. Generally, a broker-dealer’s capital is net worth plus qualified subordinated debt less deductions for certain types of assets. The Net Capital Rule requires that at least a minimum part of a broker-dealer’s assets be maintained in a relatively liquid form. If these net capital rules are changed or expanded, or if there is an unusually large charge against our net capital, our operations that require the intensive use of capital would be limited. A large operating loss or charge against our net capital could adversely affect our ability to expand or even maintain these current levels of business, which could have a material adverse effect on our business and financial condition. The U.S. regulators impose rules that require notification when net capital falls below certain predefined criteria. These rules also dictate the ratio of debt-to-equity in the regulatory capital composition of a broker-dealer, and constrain the ability of a broker-dealer to expand its business under certain circumstances. If a firm fails to maintain the required net capital, it may be subject to suspension or revocation of registration by the applicable regulatory agency, and suspension or expulsion by these regulators could ultimately lead to the firm’s liquidation. Additionally, the Net Capital Rule and certain FINRA rules impose requirements that may have the effect of prohibiting a broker-dealer from distributing or withdrawing capital and requiring prior notice to U.S. regulators and approval from FINRA for certain capital withdrawals. As of December 31, 2015, aggregate excess regulatory capital for all of the operating companies was $3.4 billion. IB LLC and TH LLC are subject to the Uniform Net Capital Rule (Rule 15c3-1) under the Exchange Act and to the CFTC’s minimum financial requirements (Regulation 1.17) under the Commodities Exchange Act; and THE is subject to the Swiss Financial Market Supervisory Authority eligible equity requirement. Additionally, Interactive Brokers Hong Kong Limited (‘‘IBHK’’) is subject to the Hong Kong Securities and Futures Commission financial resource requirement, THA is subject to the Australian Stock Exchange liquid capital requirement, Timber Hill (Lichtenstein) AG is subject to the Financial Market Authority Liechtenstein eligible capital requirements, THC and Interactive Brokers Canada Inc. (‘‘IBC’’) are subject to the Investment Industry Regulatory Organization of Canada risk adjusted capital requirement, Interactive Brokers (U.K.) Limited (‘‘IBUK’’) is subject to the U.K. Financial Conduct Authority financial resources requirement, IBI is subject to the National Stock Exchange of India net capital requirements and Interactive Brokers Securities Japan, Inc. (‘‘IBSJ’’) is subject to the Japanese Financial Supervisory Agency capital requirements. 19 The following table summarizes capital, capital requirements and excess regulatory capital: IB LLC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

For additional information regarding our net capital requirements see Note 16 to the consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K. Protection of Customer Assets To conduct customer activities, IB LLC is obligated under rules mandated by its primary regulators, the SEC and the CFTC, to segregate cash or qualified securities belonging to customers. In accordance with the Securities Exchange Act of 1934, IB LLC is required to maintain separate bank accounts for the exclusive benefit of customers. In accordance with the Commodity Exchange Act, IB LLC is required to segregate all monies, securities and property received from commodities customers in specially designated accounts. IBC, IBUK, IBHK, and IBSJ are subject to similar requirements within their respective jurisdictions. To further enhance the protection of our customers’ assets, in 2011, IB LLC sought and received approval from FINRA to perform the customer reserve computation on a daily basis, instead of once per week. IB LLC has been performing daily computations since December 2011, along with daily adjustments of the money set aside in safekeeping for our customers. Supervision and Compliance Our Compliance Department supports and seeks to ensure proper operations of our market making and electronic brokerage businesses. The philosophy of the Compliance Department, and our company as a whole, is to build automated systems to try to eliminate manual steps in the compliance process and then to augment these systems with experienced staff members who apply their judgment where needed. We have built automated systems to handle wide-ranging compliance issues such as trade and audit trail reporting, financial operations reporting, enforcement of short sale rules, enforcement of margin rules and pattern day trading restrictions, review of employee correspondence, archival of required records, execution quality and order routing reports, approval and documentation of new customer accounts, and anti-money laundering and anti-fraud surveillance. In light of our automated operations and our automated compliance systems, we have a smaller and more efficient Compliance Department than many traditional securities firms. Nonetheless, we have increased the staffing in our Compliance Department over the past several years to meet the increased regulatory burdens faced by all industry participants. Our electronic brokerage and market making companies have Chief Compliance Officers who report to the Company’s CEO, General Counsel and its Audit and Compliance Committee. These Chief Compliance Officers, plus certain other senior staff members, are FINRA and NFA registered principals with supervisory responsibility over the various aspects of our businesses. Similar roles are undertaken by staff in certain non-U.S. locations as well. Staff members in the Compliance Department and in other departments of the firm are also registered with FINRA, NFA or other regulatory organizations. 20 Patriot Act and Increased Anti-Money Laundering (‘‘AML’’) and ‘‘Know Your Customer’’ Obligations Registered broker-dealers traditionally have been subject to a variety of rules that require that they ‘‘know their customers’’ and monitor their customers’ transactions for potential suspicious activities. With the passage of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (the ‘‘Patriot Act’’), broker-dealers are subject to even more stringent requirements. Likewise, the SEC, CFTC, foreign regulators, and the various exchanges and self-regulatory organizations, of which IB companies are members, have passed numerous AML and customer due diligence rules. Significant criminal and civil penalties can be imposed for violations of the Patriot Act, and significant fines and regulatory penalties for violations of other governmental and self-regulatory organization AML rules. As required by the Patriot Act and other rules, we have established comprehensive anti-money laundering and customer identification procedures, designated AML compliance officers, trained our employees and conducted independent audits of our programs. Our anti-money laundering screening is conducted using a mix of automated and manual reviews and has been structured to comply with regulations in various jurisdictions. We collect required information through our new account opening process and screen accounts against databases for the purposes of identity verification and for review of negative information and appearance on government lists, including the Office of Foreign Assets and Control, Specially Designated Nationals and Blocked Persons lists. Additionally, we have developed methods for risk control and continue to add upon specialized processes, queries and automated reports designed to identify money laundering, fraud and other suspicious activities. Dodd-Frank Reform Act The Dodd-Frank Wall Street Reform and Consumer Protection Act imposes strict reporting and disclosure requirements on the financial services industry. We have enhanced the evidence of our supervisory review of controls over financial reporting and Management continues to monitor accounting and regulatory rulemaking developments for their potential effect on our financial statements and internal controls over financial reporting. Business Continuity Planning Federal regulators and industry self-regulatory organizations have passed a series of rules in the past several years requiring regulated firms to maintain business continuity plans that describe what actions firms would take in the event of a disaster (such as a fire, natural disaster or terrorist incident) that might significantly disrupt operations. We have developed business continuity plans that describe steps that we and our employees would take in the event of various scenarios. We have built a backup site for certain key operations at our Chicago facilities that would be utilized in the event of a significant outage at our Greenwich headquarters. In addition, we have strengthened the infrastructure at our Greenwich headquarters and have built redundancy of systems so that certain operations can be handled from multiple offices. We continually evaluate opportunities to further our business continuity planning efforts. Foreign Regulation Our international subsidiaries are subject to extensive regulation in the various jurisdictions where they have operations. The most significant of our international subsidiaries are: IBC and THC, registered to do business in Canada as an investment dealer and securities dealer, respectively; IBUK, registered to do business in the U.K. as a broker; THE, registered to do business in Switzerland as a securities dealer; IBI, registered to do business in India as a stock broker; IBHK, registered to do business in Hong Kong as a securities dealer; THA, registered to do business in Australia as a securities dealer and futures broker; and IBSJ, registered in Japan as a financial instruments firm with the Kanto Regional Finance Bureau and the Financial Supervisory Agency. 21 In Canada, both THC and IBC are subject to the Investment Industry Regulatory Organization of Canada (‘‘IIROC’’) risk adjusted capital requirement. In the United Kingdom, IBUK is subject to the U.K Financial Conduct Authority financial resources requirement. In Switzerland, THE is subject to the Swiss Financial Market Supervisory Authority eligible equity requirement. In India, IBI is subject to the National Stock Exchange and Bombay Stock Exchange capital requirements. In Hong Kong, the Securities and Futures Commission (‘‘SFC’’) regulates our subsidiary, IBHK, as a securities dealer. The compliance requirements of the SFC include, among other things, net capital requirements and stockholders’ equity requirements. The SFC regulates the activities of the officers, directors, employees and other persons affiliated with IBHK and requires the registration of such persons. In Australia, THA is subject to the Australian Stock Exchange liquid capital requirement. In Japan, IBSJ is subject to the Financial Supervisory Agency, the Osaka Securities Exchange and the Tokyo Stock Exchange capital requirements.

RISK FACTORS We face a variety of risks that are substantial and inherent in our businesses, including market, liquidity, credit, operational, legal and regulatory. In addition to the risks identified elsewhere in this Annual Report on Form 10-K, the following risk factors apply to our business results of operations and financial condition: Risks Related to Our Company Structure Control by Mr. Thomas Peterffy of a majority of the combined voting power of our common stock may give rise to conflicts of interests and could discourage a change of control that other stockholders may favor, which could negatively affect our stock price, and adversely affect stockholders in other ways. Mr. Thomas Peterffy, our founder, Chairman and Chief Executive Officer, and his affiliates beneficially own approximately 88.7% of the economic interests and all of the voting interests in Holdings, which owns all of our Class B common stock, representing approximately 84.3% of the combined voting power of all classes of our voting stock. As a result, Mr. Thomas Peterffy has the ability to elect all of the members of our board of directors and thereby to control our management and affairs, including determinations with respect to acquisitions, dispositions, material expansions or contractions of our business, entry into new lines of business, borrowings, issuances of common stock or other securities, and the declaration and payment of dividends on our common stock. In addition, Mr. Thomas Peterffy is able to determine the outcome of all matters requiring stockholder approval and will be able to cause or prevent a change of control of our company or a change in the composition of our board of directors and could preclude any unsolicited acquisition of our company. The concentration of ownership could discourage potential takeover attempts that other stockholders may favor and could deprive stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company and this may adversely affect the market price of our common stock. Moreover, because of Mr. Thomas Peterffy’s substantial ownership, we are eligible to be and are, treated as a ‘‘controlled company’’ for purposes of the NASDAQ Marketplace Rules. As a result, we are not required by NASDAQ to have a majority of independent directors or to maintain Compensation and Nominating and Corporate Governance Committees composed entirely of independent directors to continue to list the shares of our common stock on The NASDAQ Global Select Market (‘‘NASDAQ GS’’). Our Compensation Committee is comprised of Messrs. Thomas Peterffy (Chairman of the Compensation Committee) and Earl H. Nemser (our Vice Chairman). Mr. Thomas Peterffy’s membership on the Compensation Committee may give rise to conflicts of interests in that Mr. Thomas Peterffy is able to influence all matters relating to executive compensation, including his own compensation. We are dependent on IBG LLC to distribute cash to us in amounts sufficient to pay our tax liabilities and other expenses. We are a holding company and our primary assets are our approximately 15.7% equity interest in IBG LLC and our controlling interest and related rights as the sole managing member of IBG LLC and, as such, we operate and control all of the business and affairs of IBG LLC and are able to consolidate IBG LLC’s financial results into our financial statements. We have no independent means of generating revenues. IBG LLC is treated as a partnership for U.S. federal income tax purposes and, as such, is not subject to U.S. federal income tax. Instead, its taxable income is allocated on a pro rata basis to Holdings and us. Accordingly, we incur income taxes on our proportionate share of the net taxable income of IBG LLC, and also incur expenses related to our operations. We intend to cause IBG LLC to distribute cash to its members in amounts at least equal to that necessary to cover their tax liabilities, if any, with respect to the earnings of IBG LLC. To the extent we need funds to pay such 24 taxes, or for any other purpose, and IBG LLC is unable to provide such funds, it could have a material adverse effect on our business, financial condition and results of operations. We are required to pay Holdings for the benefit relating to additional tax depreciation or amortization deductions we claim as a result of the tax basis step-up our subsidiaries received in connection with our IPO and certain subsequent redemptions of Holdings membership interests. In connection with our IPO, we purchased interests in IBG LLC from Holdings for cash. In connection with redemptions of Holdings membership interests, we acquired additional interests in IBG LLC by issuing shares of Class A common stock in exchange for an equivalent number of shares of member interests in IBG LLC (the ‘‘Redemptions’’). In addition, IBG LLC membership interests held by Holdings may be sold in the future to us and financed by our issuances of shares of our common stock. The initial purchase and the Redemptions did, and the subsequent purchases may, result in increases in the tax basis of the tangible and intangible assets of IBG LLC and its subsidiaries that otherwise would not have been available. Such increase will be approximately equal to the amount by which our stock price at the time of the purchase exceeds the income tax basis of the assets of IBG LLC underlying the IBG LLC interests acquired by us. These increases in tax basis will result in increased deductions in computing our taxable income and resulting tax savings for us generally over the 15 year period which commenced with the initial purchase. We have agreed to pay 85% of these tax savings, if any, to Holdings as they are realized as additional consideration for the IBG LLC interests that we acquire. As a result of the IPO and the redemptions by Holdings, the increase in the tax basis attributable to our interest in IBG LLC is $1.2 billion. The tax savings that we would actually realize as a result of this increase in tax basis likely would be significantly less than this amount multiplied by our effective tax rate due to a number of factors, including the allocation of a portion of the increase in tax basis to foreign or non-depreciable fixed assets, the impact of the increase in the tax basis on our ability to use foreign tax credits and the rules relating to the amortization of intangible assets, for example. Based on facts and assumptions as of December 31, 2015, including that subsequent purchases of IBG LLC interests will occur in fully taxable transactions, the potential tax basis increase resulting from the historical and future purchases of the IBG LLC interests held by Holdings could be as much as $11.1 billion. The tax receivable agreement requires 85% of such tax savings, if any, to be paid to Holdings, with the balance to be retained by us. The actual increase in tax basis depends, among other factors, upon the price of shares of our common stock at the time of the purchase and the extent to which such purchases are taxable and, as a result, could differ materially from this amount. Our ability to achieve benefits from any such increase, and the amount of the payments to be made under the tax receivable agreement, depends upon a number of factors, as discussed above, including the timing and amount of our future income. The tax basis of $11.1 billion assumes that (a) all remaining IBG LLC membership interests held by Holdings are purchased by us and (b) such purchases in the future are made at prices that reflect the closing share price as of December 31, 2015. In order to have an $11.1 billion tax basis, the offering price per share of Class A common stock in such future public offering will need to exceed the then current cost basis per share of Class A common stock by approximately $31.90. If either immediately before or immediately after any purchase or the related issuance of our stock, the Holdings members own or are deemed to own, in the aggregate, more than 20% of our outstanding common stock, then all or part of any increase in the tax basis of goodwill may not be amortizable and, thus, our ability to realize the annual tax savings that otherwise would have resulted if such tax basis were amortizable may be significantly reduced. Although the Holdings members are prohibited under the Exchange Agreement from purchasing shares of Class A common stock, grants of our common stock to employees and directors who are also members or related to members of Holdings and the application of certain tax attribution rules, such as among family members and partners in a 25 partnership, could result in Holdings members being deemed for tax purposes to own shares of Class A common stock. If the Internal Revenue Services (‘‘IRS’’) successfully challenges the tax basis increase, under certain circumstances, we could be required to make payments to Holdings under the tax receivable agreement in excess of our cash tax savings. Future sales of our common stock in the public market could lower our stock price, and any additional capital raised by us through the sale of equity or convertible securities may dilute your ownership in us. The members of Holdings have the right to cause the redemption of their Holdings membership interests over time in connection with offerings of shares of our common stock. We intend to sell additional shares of common stock in public offerings in the future, which may include offerings of our common stock to finance future purchases of IBG LLC membership interests which, in turn, will finance corresponding redemptions of Holdings membership interests. These offerings and related transactions are anticipated to occur at least annually into the future. The size and occurrence of these offerings may be affected by market conditions. We may also issue additional shares of common stock or convertible debt securities to finance future acquisitions or business combinations. We currently have approximately 64 million outstanding shares of common stock. Assuming no anti-dilution adjustments based on combinations or divisions of our common stock, the offerings referred to above could result in the issuance by us of up to an additional approximately 343 million shares of common stock. It is possible, however, that such shares could be issued in one or a few large transactions. We cannot predict the size of future issuances of our common stock or the effect, if any, that future issuances and sales of shares of our common stock may have on the market price of our common stock. Sales of substantial amounts of our common stock (including shares issued in connection with an acquisition), or the perception that such sales could occur, may cause the market price of our common stock to decline. Certain provisions in our amended and restated certificate of incorporation may prevent efforts by our stockholders to change our direction or management. Provisions contained in our amended and restated certificate of incorporation could make it more difficult for a third party to acquire us, even if doing so might be beneficial to our stockholders. For example, our amended and restated certificate of incorporation authorizes our board of directors to determine the rights, preferences, privileges and restrictions of unissued series of preferred stock, without any vote or action by our stockholders. We could issue a series of preferred stock that could impede the completion of a merger, tender offer or other takeover attempt. These provisions may discourage potential acquisition proposals and may delay, deter or prevent a change of control of us, including through transactions, and, in particular, unsolicited transactions, that some or all of our stockholders might consider to be desirable. As a result, efforts by our stockholders to change our direction or management may be unsuccessful. Risks Related to Our Business Our business may be harmed by global events beyond our control, including overall slowdowns in securities trading. Like other brokerage and financial services firms, our business and profitability are directly affected by elements that are beyond our control, such as economic and political conditions, broad trends in business and finance, changes in volume of securities and futures transactions, changes in the markets in which such transactions occur and changes in how such transactions are processed. A weakness in equity markets, such as a slowdown causing reduction in trading volume in U.S. or foreign securities 26 and derivatives, has historically resulted in reduced transaction revenues and would have a material adverse effect on our business, financial condition and results of operations. Because our revenues and profitability depend on trading volume, they are prone to significant fluctuations and are difficult to predict. Our revenues are dependent on the level of trading activity on securities and derivatives exchanges in the U.S. and abroad. In the past, our revenues and operating results have varied significantly from period to period primarily due to the willingness of competitors to trade more aggressively by decreasing their bid/offer spreads and thereby assuming more risk in order to acquire market share, to movements and trends in the underlying markets, and to fluctuations in trading levels. As a result, period to period comparisons of our revenues and operating results may not be meaningful, and future revenues and profitability may be subject to significant fluctuations or declines. Our reliance on our computer software could cause us great financial harm in the event of any disruption or corruption of our computer software. We may experience technology failures while developing our software. We rely on our computer software to receive and properly process internal and external data. Any disruption for any reason in the proper functioning or any corruption of our software or erroneous or corrupted data may cause us to make erroneous trades or suspend our services and could cause us great financial harm. To maintain our competitive advantage, our software is under continuous development. As we identify and enhance our software, there is risk that software failures may occur and result in service interruptions and have other unintended consequences. Our business could be harmed by a systemic market event. Some market participants could be overleveraged. In case of sudden, large price movements, such market participants may not be able to meet their obligations to brokers who, in turn, may not be able to meet their obligations to their counterparties. As a result, the financial system or a portion thereof could collapse, and the impact of such an event could be catastrophic to our business. We may incur material trading losses from our market making activities. A substantial portion of our revenues and operating profits is derived from our trading as principal in our role as a market maker and specialist. We may incur trading losses relating to these activities since each primarily involves the purchase or sale of securities for our own account. In any period, we may incur trading losses in a significant number of securities for a variety of reasons including: (cid:129) price changes in securities; (cid:129) lack of liquidity in securities in which we have positions; and (cid:129) the required performance of our market making and specialist obligations. These risks may limit or restrict our ability to either resell securities we purchased or to repurchase securities we sold. In addition, we may experience difficulty borrowing securities to make delivery to purchasers to whom we sold short, or lenders from whom we have borrowed. From time to time, we have large position concentrations in securities of a single issuer or issuers engaged in a specific industry or traded in a particular market. Such a concentration could result in higher trading losses than would occur if our positions and activities were less concentrated. In our role as a market maker, we attempt to derive a profit from the difference between the prices at which we buy and sell, or sell and buy, securities. However, competitive forces often require us to match the quotes other market makers display and to hold varying amounts of securities in inventory. By having to maintain inventory positions, we are subjected to a high degree of risk. We cannot assure you that we will be able to manage such risk successfully or that we will not experience significant losses from such activities, which could have a material adverse effect on our business, financial condition and results of operations. 27 Reduced spreads in securities pricing, levels of trading activity and trading through market makers and/or specialists could harm our business. Computer-generated buy/sell programs and other technological advances and regulatory changes in the marketplace may continue to tighten spreads on securities transactions. Tighter spreads and increased competition could make the execution of trades and market making activities less profitable. In addition, new and enhanced alternative trading systems such as ECNs have emerged as an alternative for individual and institutional investors, as well as broker-dealers, to avoid directing their trades through market makers, and could result in reduced revenues derived from our market making business. We may incur losses in our market making activities in the event of failures of our proprietary pricing model. The success of our market making business is substantially dependent on the accuracy of our proprietary pricing mathematical model, which continuously evaluates and monitors the risks inherent in our portfolio, assimilates market data and reevaluates our outstanding quotes each second. Our model is designed to automatically rebalance our positions throughout the trading day to manage risk exposures on our positions in options, futures and the underlying securities. In the event of a flaw in our pricing model and/or a failure in the related software, our pricing model may lead to unexpected and/or unprofitable trades, which may result in material trading losses. The valuation of the financial instruments we hold may result in large and occasionally anomalous swings in the value of our positions and in our earnings in any period. The market prices of our long and short positions are reflected on our books at closing prices which are typically the last trade price before the official close of the primary exchange on which each such security trades. Given that we manage a globally integrated portfolio, we may have large and substantially offsetting positions in securities that trade on different exchanges that close at different times of the trading day. As a result, there may be large and occasionally anomalous swings in the value of our positions daily and, accordingly, in our earnings in any period. This is especially true on the last business day of each calendar quarter. We are exposed to losses due to lack of perfect information. As market makers, we provide liquidity by buying from sellers and selling to buyers. Quite often, we trade with others who have different information than we do, and as a result, we may accumulate unfavorable positions preceding large price movements in companies. Should the frequency or magnitude of these events increase, our losses will likely increase correspondingly. Rules governing specialists and designated market makers may require us to make unprofitable trades or prevent us from making profitable trades. Specialists and designated market makers are granted certain rights and have certain obligations to ‘‘make a market’’ in a particular security. They agree to specific obligations to maintain a fair and orderly market. In acting as a specialist or designated market maker, we are subjected to a high degree of risk by having to support an orderly market. In this role, we may at times be required to make trades that adversely affect our profitability. In addition, we may at times be unable to trade for our own account in circumstances in which it may be to our advantage to trade, and we may be obligated to act as a principal when buyers or sellers outnumber each other. In those instances, we may take a position counter to the market, buying or selling securities to support an orderly market. Additionally, the rules of the markets which govern our activities as a specialist or designated market maker are subject to change. If these rules are made more stringent, our trading revenues and profits as specialist or designated market maker could be adversely affected. 28 We are subject to potential losses as a result of our clearing and execution activities. As a clearing member firm providing financing services to certain of our brokerage customers, we are ultimately responsible for their financial performance in connection with various stock, options and futures transactions. Our clearing operations require a commitment of our capital and, despite safeguards implemented by our software, involve risks of losses due to the potential failure of our customers to perform their obligations under these transactions. If our customers default on their obligations, we remain financially liable for such obligations, and although these obligations are collateralized, we are subject to market risk in the liquidation of customer collateral to satisfy those obligations. There can be no assurance that our risk management procedures will be adequate. Any liability arising from clearing operations could have a material adverse effect on our business, financial condition and results of operations. As a clearing member firm of securities and commodities clearing houses in the U.S. and abroad, we are also exposed to clearing member credit risk. Securities and commodities clearing houses require member firms to deposit cash and/or government securities to a clearing fund. If a clearing member defaults in its obligations to the clearing house in an amount larger than its own margin and clearing fund deposits, the shortfall is absorbed pro rata from the deposits of the other clearing members. Many clearing houses of which we are members also have the authority to assess their members for additional funds if the clearing fund is depleted. A large clearing member default could result in a substantial cost to us if we are required to pay such assessments. We may not pay dividends on our common stock at any time in the foreseeable future. As a holding company for our interest in IBG LLC, we will be dependent upon the ability of IBG LLC to generate earnings and cash flows and distribute them to us so that we may pay any dividends to our stockholders. To the extent (if any) that we have excess cash, any decision to declare and pay dividends in the future will be made at the discretion of our board of directors and will depend on, among other things, our results of operations, financial conditions, cash requirement, contractual restrictions and other factors that our board of directors may deem relevant. In December 2010 and December 2012, special cash dividends were paid to holders of our common stock. Since the second quarter of 2011, we have declared and paid a quarterly cash dividend of $0.10 per share. Although not required, we currently intend to pay quarterly dividends of $0.10 per share to our common stockholders for the foreseeable future. Regulatory and legal uncertainties could harm our business. The securities and derivatives businesses are heavily regulated. Firms in financial service industries have been subject to an increasingly regulated environment over recent years, and penalties and fines sought by regulatory authorities have increased accordingly. This regulatory and enforcement environment has created uncertainty with respect to various types of transactions that historically had been entered into by financial services firms and that were generally believed to be permissible and appropriate. Our broker-dealer subsidiaries are subject to regulations in the U.S. and abroad covering all aspects of their business. Regulatory bodies include, in the U.S., the SEC, FINRA, the Board of Governors of the Federal Reserve System, the Chicago Board Options Exchange, the Chicago Mercantile Exchange, the CFTC, and the NFA; in Canada, the Investment Industry Regulatory Organization of Canada and various Canadian securities commissions; in the United Kingdom, the Financial Conduct Authority; in Switzerland, the Swiss Financial Market Supervisory Authority; in India, the Securities and Exchange Board of India; in Hong Kong, the Securities and Futures Commission; in Australia, the Australian Securities and Investment Commission; and in Japan, the Financial Supervisory Agency and the Japan Securities Dealers Association. Our mode of operation and profitability may be directly affected by additional legislation changes in rules promulgated by various domestic and foreign government agencies and self-regulatory organizations that oversee our businesses, and changes in the interpretation 29 or enforcement of existing laws and rules, including the potential imposition of transaction taxes. Noncompliance with applicable laws or regulations could result in sanctions being levied against us, including fines and censures, suspension or expulsion from a certain jurisdiction or market or the revocation or limitation of licenses. Noncompliance with applicable laws or regulations could adversely affect our reputation, prospects, revenues and earnings. In addition, changes in current laws or regulations or in governmental policies could adversely affect our business, financial condition and results of operations. Domestic and foreign stock exchanges, other self-regulatory organizations and state and foreign securities commissions can censure, fine, issue cease-and-desist orders, suspend or expel a broker-dealer or any of its officers or employees. Our ability to comply with all applicable laws and rules is largely dependent on our internal system to ensure compliance, as well as our ability to attract and retain qualified compliance personnel. We could be subject to disciplinary or other actions in the future due to claimed noncompliance, which could have a material adverse effect on our business, financial condition and results of operations. To continue to operate and to expand our services internationally, we may have to comply with the regulatory controls of each country in which we conduct, or intend to conduct business, the requirements of which may not be clearly defined. The varying compliance requirements of these different regulatory jurisdictions, which are often unclear, may limit our ability to continue existing international operations and further expand internationally. Our future efforts to sell shares or raise additional capital may be delayed or prohibited by regulations. As certain of our subsidiaries are members of FINRA, we are subject to certain regulations regarding changes in control of our ownership. FINRA Rule 1017 generally provides that FINRA approval must be obtained in connection with any transaction resulting in a change in control of a member firm. FINRA defines control as ownership of 25% or more of the firm’s equity by a single entity or person and would include a change in control of a parent company. IBUK is subject to similar change in control regulations promulgated by the FCA in the United Kingdom. As a result of these regulations, our future efforts to sell shares or raise additional capital may be delayed or prohibited. We may be subject to similar restrictions in other jurisdictions in which we operate. We depend on our proprietary technology, and our future results may be impacted if we cannot maintain technological superiority in our industry. Our success in the past has largely been attributable to our sophisticated proprietary technology that has taken many years to develop. We have benefited from the fact that the type of proprietary technology equivalent to that which we employ has not been widely available to our competitors. If our technology becomes more widely available to our current or future competitors for any reason, our operating results may be adversely affected. Additionally, adoption or development of similar or more advanced technologies by our competitors may require that we devote substantial resources to the development of more advanced technology to remain competitive. The markets in which we compete are characterized by rapidly changing technology, evolving industry standards and changing trading systems, practices and techniques. Although we have been at the forefront of many of these developments in the past, we may not be able to keep up with these rapid changes in the future, develop new technology, realize a return on amounts invested in developing new technologies or remain competitive in the future. The loss of our key employees would materially adversely affect our business. Our key executives have substantial experience and have made significant contributions to our business, and our continued success is dependent upon the retention of our key management executives, as well as the services provided by our staff of trading system, technology and programming specialists and a number of other key managerial, marketing, planning, financial, technical and operations personnel. The loss of such key personnel could have a material adverse effect on our business. Growth in our business is dependent, to a large degree, on our ability to retain and attract such employees. 30 We are exposed to risks associated with our international operations. During 2015, approximately 30% of our net revenues were generated by our operating companies outside the U.S. We are exposed to risks and uncertainties inherent in doing business in international markets, particularly in the heavily regulated brokerage industry. Such risks and uncertainties include political, economic and financial instability; unexpected changes in regulatory requirements, tariffs and other trade barriers; exchange rate fluctuations; applicable currency controls; and difficulties in staffing, including reliance on newly hired local experts, and managing foreign operations. These risks could cause a material adverse effect on our business, financial condition and results of operations. We do not have fully redundant systems. System failures could harm our business. If our systems fail to perform, we could experience unanticipated disruptions in operations, slower response times or decreased customer service and customer satisfaction. Our ability to facilitate transactions successfully and provide high quality customer service also depends on the efficient and uninterrupted operation of our computer and communications hardware and software systems. Our service has experienced periodic system interruptions, which we believe will continue to occur from time to time. Our systems and operations also are vulnerable to damage or interruption from human error, natural disasters, power loss, telecommunication failures, break-ins, sabotage, computer viruses, intentional acts of vandalism and similar events. While we currently maintain redundant servers to provide limited service during system disruptions, we do not have fully redundant systems, and our formal disaster recovery plan does not include restoration of all services. For example, we have backup facilities at our disaster recovery site that enable us, in the case of complete failure of our main North America data center, to recover and complete all pending transactions, provide customers with access to their accounts to deposit or withdraw money, transfer positions to other brokers and manage their risk by continuing trading through the use of marketable orders. These backup services are currently limited to U.S. markets. We do not currently have separate backup facilities dedicated to our non-U.S. operations. It is our intention to provide for and progressively deploy backup facilities for our global facilities over time. In addition, we do not carry business interruption insurance to compensate for losses that could occur to the extent not required. Any system failure that causes an interruption in our service or decreases the responsiveness of our service could impair our reputation, damage our brand name and materially adversely affect our business, financial condition and results of operations. Failure of third-party systems on which we rely could adversely affect our business. We rely on certain third-party computer systems or third-party service providers, including clearing systems, exchange systems, Internet service, communications facilities and other facilities. Any interruption in these third-party services, or deterioration in their performance, could be disruptive to our business. If our arrangement with any third party is terminated, we may not be able to find an alternative source of systems support on a timely basis or on commercially reasonable terms. This could have a material adverse effect on our business, financial condition and results of operations. We face competition in our market making activities. In our market making activities, we compete with other firms based on our ability to provide liquidity at competitive prices and to attract order flow. These firms include registered market makers as well as HFTs that act as market makers. Both types of competitors range from sole proprietors with very limited resources to a few highly sophisticated groups which have substantially greater financial and other resources, including research and development personnel, than we do. These larger and better capitalized competitors may be better able to respond to changes in the market making industry, to compete for skilled professionals, to finance acquisitions, to fund internal growth and to compete for market share generally. HFTs that are not registered market makers have certain advantages over registered market making firms that may allow them to bypass regulatory restrictions and trade more 31 quickly and cheaply than registered market makers at some exchanges. We may not be able to compete effectively against HFTs or market makers with greater financial resources, and our failure to do so could materially and adversely affect our business, financial condition and results of operations. As in the past, we may in the future face enhanced competition, resulting in narrowing bid/offer spreads in the marketplace that may adversely impact our financial performance. This is especially likely if HFTs continue to receive advantages in capturing order flow or if others can acquire systems that enable them to predict markets or process trades more efficiently than we can. Our direct market access clearing and non-clearing brokerage operations face intense competition. With respect to our direct market access brokerage business, the market for electronic and interactive bidding, offering and trading services in connection with equities, options and futures is relatively new, rapidly evolving and intensely competitive. We expect competition to continue and intensify in the future. Our current and potential future competition principally comes from five categories of competitors: (cid:129) prime brokers who, in an effort to satisfy the demands of their customers for hands-on electronic trading facilities, universal access to markets, smart routing, better trading tools, lower commissions and financing rates, have embarked upon building such facilities and product enhancements; (cid:129) direct market access and online options and futures firms; (cid:129) direct market access and online equity brokers; (cid:129) software development firms and vendors who create global trading networks and analytical tools and make them available to brokers; and (cid:129) traditional brokers. In addition, we compete with financial institutions, mutual fund sponsors and other organizations, many of which provide online, direct market access or other investing services. A number of brokers provide our technology and execution services to their customers, and these brokers will become our competitors if they develop their own technology. Some of our competitors in this area have greater name recognition, longer operating histories and significantly greater financial, technical, marketing and other resources than we have and offer a wider range of services and financial products than we do. Some of our competitors may also have an ability to charge lower commissions. We cannot assure you that we will be able to compete effectively or efficiently with current or future competitors. These increasing levels of competition in the online trading industry could significantly harm this aspect of our business. We are subject to risks relating to litigation and potential securities laws liability. We are exposed to substantial risks of liability under federal and state securities laws, other federal and state laws and court decisions, as well as rules and regulations promulgated by the SEC, the CFTC, the Federal Reserve, state securities regulators, self-regulatory organizations and foreign regulatory agencies. We are also subject to the risk of litigation and claims that may be without merit. We could incur significant legal expenses in defending ourselves against and resolving lawsuits or claims. An adverse resolution of any future lawsuits or claims against us could result in a negative perception of our company and cause the market price of our common stock to decline or otherwise have an adverse effect on our business, financial condition and results of operations. See Part I, Item 3, ‘‘Legal Proceedings and Regulatory Matters.’’ 32 Any future acquisitions may result in significant transaction expenses, integration and consolidation risks and risks associated with entering new markets, and we may be unable to profitably operate our consolidated company. Although our growth strategy has not focused historically on acquisitions, we may in the future engage in evaluations of potential acquisitions and new businesses. We may not have the financial resources necessary to consummate any acquisitions in the future or the ability to obtain the necessary funds on satisfactory terms. Any future acquisitions may result in significant transaction expenses and risks associated with entering new markets in addition to integration and consolidation risks. Because acquisitions historically have not been a core part of our growth strategy, we have no material experience in successfully utilizing acquisitions. We may not have sufficient management, financial and other resources to integrate any such future acquisitions or to successfully operate new businesses and we may be unable to profitably operate our expanded company. Internet-related issues may reduce or slow the growth in the use of our services in the future. Critical issues concerning the commercial use of the Internet, such as ease of access, security, privacy, reliability, cost, and quality of service, remain unresolved and may adversely impact the growth of Internet use. If Internet usage continues to increase rapidly, the Internet infrastructure may not be able to support the demands placed on it by this growth, and its performance and reliability may decline. Although our larger institutional customers use leased data lines to communicate with us, our ability to increase the speed with which we provide services to consumers and to increase the scope and quality of such services is limited by and dependent upon the speed and reliability of our customers’ access to the Internet, which is beyond our control. If periods of decreased performance, outages or delays on the Internet occur frequently or other critical issues concerning the Internet are not resolved, overall Internet usage or usage of our web based products could increase more slowly or decline, which could have a material adverse effect on our business, financial condition and results of operations. Our computer infrastructure may be vulnerable to security breaches. Any such problems could jeopardize confidential information transmitted over the Internet, cause interruptions in our operations or cause us to have liability to third persons. Our computer infrastructure is potentially vulnerable to physical or electronic computer break-ins, viruses and similar disruptive problems and security breaches. Any such problems or security breaches could cause us to have liability to one or more third parties, including our customers, and disrupt our operations. A party able to circumvent our security measures could misappropriate proprietary information or customer information, jeopardize the confidential nature of information transmitted over the Internet or cause interruptions in our operations. Concerns over the security of Internet transactions and the privacy of users could also inhibit the growth of the Internet or the electronic brokerage industry in general, particularly as a means of conducting commercial transactions. To the extent that our activities involve the storage and transmission of proprietary information such as personal financial information, security breaches could expose us to a risk of financial loss, litigation and other liabilities. Our estimated annual losses from reimbursements to customers whose accounts have been negatively affected by unauthorized access have historically been less than $500,000 annually, but instances of unauthorized access of customer accounts have been increasing recently on an industry-wide basis. Our current insurance program may protect us against some, but not all, of such losses. Any of these events, particularly if they (individually or in the aggregate) result in a loss of confidence in our company or electronic brokerage firms in general, could have a material adverse effect on our business, financial condition and results of operations. 33 We may not be able to protect our intellectual property rights or may be prevented from using intellectual property necessary for our business. We rely primarily on trade secret, contract, copyright, patent and trademark laws to protect our proprietary technology. It is possible that third parties may copy or otherwise obtain and use our proprietary technology without authorization or otherwise infringe on our rights. We may also face claims of infringement that could interfere with our ability to use technology that is material to our business operations. In the future, we may have to rely on litigation to enforce our intellectual property rights, protect our trade secrets, determine the validity and scope of the proprietary rights of others or defend against claims of infringement or invalidity. Any such litigation, whether successful or unsuccessful, could result in substantial costs and the diversion of resources and the attention of management, any of which could negatively affect our business. Our future success will depend on our response to the demand for new services, products and technologies. The demand for market making services, particularly services that rely on electronic communications gateways, is characterized by: (cid:129) rapid technological change; (cid:129) changing customer demands; (cid:129) the need to enhance existing services and products or introduce new services and products; and (cid:129) evolving industry standards. New services, products and technologies may render our existing services, products and technologies less competitive. Our future success will depend, in part, on our ability to respond to the demand for new services, products and technologies on a timely and cost-effective basis and to adapt to technological advancements and changing standards to address the increasingly sophisticated requirements and varied needs of our customers and prospective customers. We cannot assure you that we will be successful in developing, introducing or marketing new services, products and technologies. In addition, we may experience difficulties that could delay or prevent the successful development, introduction or marketing of these services and products, and our new service and product enhancements may not achieve market acceptance. Any failure on our part to anticipate or respond adequately to technological advancements, customer requirements or changing industry standards, or any significant delays in the development, introduction or availability of new services, products or enhancements could have a material adverse effect on our business, financial condition and results of operations. Market making in forex-based products entails significant risk, and unforeseen events in such business could have an adverse effect on our business, financial condition and results of operations. Our activities in market making for forex-based products include the trading of cash in foreign currencies with banks and exchange-listed futures, options on futures, options on cash deposits and currency-based ETFs. All of the risks that pertain to our market making activities in equity-based products also apply to our forex-based market making. In addition, we have comparatively less experience in the forex markets and various unexpected events can occur that may result in great financial loss. 34 We are subject to counterparty risk whereby defaults by parties with whom we do business can have an adverse effect on our business, financial condition and results of operations. In our electronic brokerage business, our customer margin credit exposure is to a great extent mitigated by our policy of automatically evaluating each account throughout the trading day and closing out positions automatically for accounts that are found to be under-margined. While this methodology is effective in most situations, it may not be effective in situations in which no liquid market exists for the relevant securities or commodities or in which, for any reason, automatic liquidation for certain accounts has been disabled. If no liquid market exists or automatic liquidation has been disabled, we are subject to risks inherent in extending credit, especially during periods of rapidly declining markets. Any loss or expense incurred due to defaults by our customers in failing to repay margin loans or to maintain adequate collateral for these loans would cause harm to our business, financial condition and results of operations. ITEM 1B. UNRESOLVED STAFF COMMENTS None. ITEM 2. PROPERTIES Our headquarters are located in Greenwich, Connecticut. We also lease facilities in 18 other locations throughout parts of the world where we conduct our operations as set forth below. Unless otherwise indicated, all properties are used by both our market making and electronic brokerage segments.

LEGAL PROCEEDINGS AND REGULATORY MATTERS The securities and commodities industry is highly regulated and many aspects of our business involve substantial risk of liability. In recent years, there has been an increasing incidence of litigation involving the brokerage industry, including class action suits that generally seek substantial damages, including in some cases punitive damages. Compliance and trading problems that are reported to federal, state and provincial regulators, exchanges or other self-regulatory organizations by dissatisfied customers are investigated by such regulatory bodies, and, if pursued by such regulatory body or such customers, may rise to the level of arbitration or disciplinary action. We are also subject to periodic regulatory audits and inspections. Like other brokerage firms, we have been named as a defendant in lawsuits and from time to time we have been threatened with, or named as a defendant in, arbitrations and administrative proceedings. The following contains information regarding potentially material pending litigation and pending regulatory inquiries. We may in the future become involved in additional litigation or regulatory proceedings in the ordinary course of our business, including litigation or regulatory proceedings that could be material to our business. Trading Technologies Matter On February 3, 2010, Trading Technologies International, Inc. (‘‘Trading Technologies’’) commenced an action in the U.S. District Court for the Northern District of Illinois, Eastern Division, against IBG LLC and IB LLC (‘‘Defendants’’) alleging infringement of twelve U.S. patents and seeking, among other things, unspecified damages and injunctive relief. The Defendants filed an answer denying the claims and asserted counterclaims seeking a declaration that the patents have not been infringed and are invalid. The Defendants and/or certain codefendants filed petitions with the U.S. Patent and Trademark Office (‘‘USPTO’’) for Covered Business Method (‘‘CBM’’) Review on eight of the asserted patents, and will likely file petitions with respect to the others. Thus far the USPTO issued decisions instituting CBM Review on two of the asserted patents and has made a finding that it is more likely than not that the patents are invalid. While it is too early to predict the outcome of the matter, we believe we have meritorious defenses to the allegations made in the complaint and intend to defend ourselves vigorously against them. Class Action Matter On December 18, 2015, a former individual customer filed a purported class action complaint against IB LLC, IBG, Inc., and Thomas Frank, PhD, the Company’s Executive Vice President and Chief Information Officer, in the U.S. District Court for the District of Connecticut. The complaint alleges that the former customer and members of the purported class of IB LLC’s customers were harmed by alleged ‘‘flaws’’ in the computerized system used by the Company to close out (i.e., liquidate) positions in customer brokerage accounts that have margin deficiencies. The complaint seeks, among other things, undefined compensatory damages and declaratory and injunctive relief. We believe that the complaint is without merit and we have filed a motion to dismiss it. Among other things, the Company’s customer agreement, federal law and associated industry rules grant broker- dealers broad discretion to close out margin-deficient customer accounts for the broker’s protection. Further, we do not believe that a purported class action is appropriate given the great differences in portfolios, markets and many other circumstances surrounding the liquidation of any particular customer’s margin-deficient account. IB LLC and the related defendants intend to defend themselves vigorously against the case and, consistent with past practice in connection with this type of unwarranted action, any potential claims for counsel fees and expenses incurred in defending the case shall be fully pursued against the plaintiff. 36 Pending Regulatory Inquiries Our businesses are heavily regulated by state, federal and foreign regulatory agencies as well as numerous exchanges and self-regulatory organizations. Most of our companies are regulated under state securities laws, U.S. and foreign securities, commodities and financial services laws and under the rules of more than 25 exchanges and self-regulatory organizations. In the current era of dramatically heightened regulatory scrutiny of financial institutions, we have incurred sharply increased compliance costs, along with the industry as a whole. Increased regulation also creates increased barriers to entry, however, we have built human and automated infrastructure to handle increased regulatory scrutiny, which provides us with an advantage over potential newcomers to the business. We receive hundreds of regulatory inquiries each year in addition to being subject to frequent regulatory examinations. The great majority of these inquiries do not lead to fines or any further action against us. Most often, regulators do not inform us as to when and if an inquiry has been concluded. We are currently the subject of regulatory inquiries regarding topics such as order audit trail reporting, trade reporting, short sales, margin lending, anti-money laundering, technology development practices, business continuity planning and other topics of recent regulatory interest. We are unaware of any specific regulatory matter that, itself, or together with similar regulatory matters, would have a material impact on our business, financial condition and results of operations. Nonetheless, in the current climate, we expect to pay significant regulatory fines on various topics on an ongoing basis, as other regulated financial services businesses do. The amount of any fines, and when and if they will be incurred, is impossible to predict given the nature of the regulatory process. ITEM 4. MINE SAFETY DISCLOSURES Not applicable. 37 PART II ITEM 5.

Holders On February 19, 2016, there were five holders of record, which does not reflect those shares held beneficially or those shares held in ‘‘street’’ name. Accordingly, the number of beneficial owners of our common stock exceeds this number. Dividends and Other Restrictions During the second quarter of 2011, we declared and paid a cash dividend of $0.10 per share and have continued this quarterly dividend policy through the current fiscal year end and into the first quarter of 2016. We currently intend to pay quarterly dividends of $0.10 per share to our common stockholders for the foreseeable future. 38 Stockholder Return Performance Graph The following graph compares cumulative total stockholder return on our common stock, the S&P 500 Index and the NASDAQ Financial-100 Index from December 31, 2010 to December 31, 2015. The comparison assumes $100 was invested on December 31, 2010 in our common stock and each of the foregoing indices and assumes reinvestment of dividends before consideration of income taxes.

(2) The S&P 500 Index includes 500 large cap common stocks actively traded in the U.S. The stocks included in the S&P 500 are those of large publicly held companies that trade on either of the two largest American stock markets, the New York Stock Exchange and NASDAQ. The stock performance depicted in the graph above is not to be relied upon as indicative of future performance. The stock performance graph shall not be deemed to be incorporated by reference into any of our filings under the Securities Act or the Exchange Act, except to the extent that we specifically incorporate the same by reference, nor shall it be deemed to be ‘‘soliciting material’’ or to be ‘‘filed’’ with the SEC or subject to Regulations 14A or 14C or to the liabilities of Section 18 of the Exchange Act. Use of Proceeds from Member Redemption Purchases of IBG LLC membership interests, held by Holdings, by the Company are governed by the Exchange Agreement, a copy of which was filed as an exhibit to our Quarterly Report on Form 10-Q for the quarter ended September 30, 2009 and filed with the SEC on November 9, 2009. The Exchange Agreement, as amended June 6, 2012 and July 23, 2015, provides that the Company may facilitate the redemption by Holdings of interests held by its members through the issuance of shares of common stock through a public offering in exchange for the interests in IBG LLC being redeemed by Holdings. On an annual basis, each holder of a membership interest may request that Holdings redeem the liquefiable portion of that holder’s interest. We expect Holdings to use the net proceeds it receives from such sales to redeem an identical number of Holdings membership interests from the requesting holders. At the time of the Company’s IPO in 2007, three hundred sixty (360) million shares of authorized common stock were reserved for future sales and redemptions. From 2008 through 2014, Holdings redeemed 13,038,776 IBG LLC shares with an approximate total value of $288 million, which redemptions were funded using cash on hand at IBG LLC and through issuances of common stock. 39 With the consent of Holdings and the Company (on its own behalf and acting as the sole managing member of IBG LLC), IBG LLC agreed in July and December of 2015 to redeem certain membership interests from Holdings through the sale of common stock and the distribution of the proceeds of such sale to the beneficial owners of such membership interests. On July 24, 2015, the Company issued 2,771,778 shares of Class A common stock (with a fair value of approximately $121 million) to Holdings, for sale for the benefit of, certain of its members in exchange for membership interests in IBG LLC equal in number to such number of shares of common stock issued by the Company. The acquired shares were sold for the benefit of certain of the members of Holdings who elected to redeem a portion of their Holdings membership interests. The shares were sold in open market transactions pursuant to a trading plan established in conformity with Rule 10b5-1 of the Exchange Act (the ‘‘Plan’’). Certain officers and directors were among the members of Holdings who elected to redeem a portion of their Holdings membership interests and therefore had an interest in the proceeds of the sale of 1,125,018 shares of the Class A common stock sold pursuant to the Plan. In addition, certain current and former employees of the Company and its subsidiaries also elected the redemption of a portion of their membership interests in Holdings and therefore had an interest in the balance of the shares sold under the Plan. In addition, on December 24, 2015, the Company issued 250,000 shares of Class A common stock (with a fair value of approximately $11 million) to Holdings, which distributed these 250,000 shares to Mr. Thomas Peterffy in partial redemption of his Holdings interest. It is our understanding that Mr. Thomas Peterffy subsequently donated these 250,000 shares to a newly created private charitable foundation. As a consequence of the two member redemptions in 2015, IBG, Inc.’s interest in IBG LLC increased to approximately 15.7%, with Holdings owning the remaining 84.3%. The redemptions also resulted in an increase in the Holdings interest held by Mr. Thomas Peterffy and his affiliates from approximately 88.0% to approximately 88.7%. On October 13, 2015, the Company filed a Post-Effective Amendment to multiple Registration Statements filed under the Securities Act of 1933, as amended (the ‘‘Securities Act’’) on Form S-8 that registered shares of the Company’s Class A common stock, $0.01 par value, for issuance under the Company’s 2007 Stock Incentive Plan (the ‘‘Plan’’): Registration No. 333-142686, filed on May 7, 2007; Registration No. 333-174913, filed on June 15, 2011; and Registration No. 333-203358, filed on April 10, 2015. The Plan provides employees with two options to pay for their withholding tax obligations, which become due when shares vest: either (1) reimburse the Company via cash payment, or (2) elect to have the Selling Stockholder withhold a portion of the vesting shares. In the case of employees who elect to have the IBG LLC withhold shares to cover their tax obligations, those shares are transferred to IBG LLC, which in turn, sells those shares in open market transactions to recover the amount paid to the tax authorities on the employees’ behalf. As of December 31, 2015 the Company has sold all 721,279 shares of its Class A common stock, that were withheld from employees, (with a fair value of $29 million), in open market transactions. The proceeds were used to reimburse the Company for withholding taxes paid by the Company on the employees’ behalf. As per General Instruction C of Form S-8, the sale of the shares described above constitutes a resale or reoffer of the Company’s Class A common stock. The Post-Effective Amendment, contains a reoffer prospectus that registers 6,400,000 shares of the Company’s Class A common stock which represents the Company’s estimate of shares that will be withheld from employees related to the vesting of Plan shares over the next nine years based on current tax rates and historical employee elections. The 40 reoffer prospectus allows for future sales by IBG LLC, on a continuous or delayed basis, to the public without restriction. Securities Authorized for Issuance under Equity Compensation Plans The following table provides information about shares of common stock available for future awards under all of the Company’s equity compensation plans as of December 31, 2015. The Company has not made grants of common stock outside of its equity compensation plans: Number of securities to be issued upon exercise of outstanding options, warrants and rights Weighted-average exercise price of outstanding options warrants and rights Number of securities remaining available for future issuance under equity compensation plans(1) Equity compensation plans approved by security holders . . . . . . . . . . . . . .

The amount excludes shares purchased from employees to satisfy their tax withholding obligations for vested shares, which are held as treasury stock. No shares are available for future issuance of grants under the 2007 ROI Unit Stock Plan; all shares under this plan have been granted. 41 ITEM 6.

In connection with the special dividend paid by our Swiss operating company, THE, in December 2010, we were able to capture additional foreign tax credits, which resulted in an estimated $0.12 increase in diluted earnings per share. 42 2015 2014 2013 2012 2011 December 31, (in millions) Consolidated Statement of Financial Condition Data Cash, cash equivalents and short-term investments(1) Total assets(2)(3) . . . . . . . . . . . . . . . . . . . . . . . . . .

(2) As of December 31, 2015, approximately $48.3 billion, or 99.2%, of total assets were considered to be liquid and consisted primarily of cash, marketable securities and collateralized receivables. (3) As a result of the Company’s acquisition from Holdings of IBG LLC membership interests, the Company received not only an interest in IBG LLC but also, for federal income tax purposes, a step-up to the federal income tax basis of the assets of IBG LLC underlying such additional interest. This increased tax basis is expected to result in tax benefits as a result of increased amortization deductions. The Company will retain 15% of the tax benefits actually realized. As set forth in the tax receivable agreement the Company entered into with Holdings, the Company will pay the remaining 85% of the realized tax benefits relating to any applicable tax year to Holdings. The deferred tax asset was $288 million, $279 million, $295 million, $282 million and $298 million and the corresponding payable to Holdings was $291 million, $277 million, $287 million, $259 million and $272 million as of December 31, 2015, 2014, 2013, 2012 and 2011, respectively. (4) Prior to June 6, 2012, the Company reported Holdings’ interests in IBG LLC as redeemable noncontrolling interests, at redemption value and separate from equity. Redemption value for these redeemable noncontrolling interests was measured as the number of equivalent shares of IBG LLC member interests owned by Holdings multiplied by the then current market price per share of the Company’s common stock. The excess of the redemption value over the book value of these interests, which did not affect net income attributable to common stockholders or cash flows, was required to be accounted for as a reduction of the Company’s stockholders’ equity in the consolidated statements of financial condition. These fair value adjustments had the effect of decreasing reported stockholders’ equity by $1.0 billion as of December 31, 2011. Accordingly, the above condensed consolidated statement of financial condition information is presented as if ASC 810-10 and ASC 480-10-S99 had been applied historically. Subsequent to June 6, 2012, the Company has reported noncontrolling interests attributable to Holdings as a component of the Company’s total equity, valued based on Holding’s proportionate ownership in IBG LLC. (5) In December of 2012, the Company paid a special cash dividend of $1.00 per share to holders of the Company’s common stock. The payment of this dividend resulted in a decrease in the Company’s stockholders’ equity (deficit) balances from prior years. 43 ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion should be read in conjunction with the audited consolidated financial statements and the related notes in Item 8, included elsewhere in this report. In addition to historical information, the following discussion also contains forward-looking statements that include risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth under the heading ‘‘Risk Factors’’ in Part I, Item 1A of this Annual Report on Form 10-K. Business Overview We are an automated global electronic broker and market maker. We custody and service accounts for hedge and mutual funds, registered investment advisers, proprietary trading groups, introducing brokers and individual investors. We specialize in routing orders and executing and processing trades in securities, futures and foreign exchange instruments on more than 100 electronic exchanges and market centers around the world. Since our inception in 1977, we have focused on developing proprietary software to automate broker-dealer functions. The proliferation of electronic exchanges in the last 25 years has provided us with the opportunity to integrate our software with an increasing number of exchanges and market centers into one automatically functioning, computerized platform that requires minimal human intervention. In connection with our IPO priced on May 3, 2007, IBG, Inc. purchased 10.0% of the membership interests in IBG LLC, became the sole managing member of IBG LLC and began to consolidate IBG LLC’s financial results into its financial statements. Our primary assets are our ownership of approximately 15.7% of the membership interests of IBG LLC, the current holding company for our businesses, and our controlling interest and related contractual rights as the sole managing member of IBG LLC. The remaining approximately 84.3% of IBG LLC membership interests are held by Holdings, a holding company that is owned by our founder, Chairman and Chief Executive Officer, Mr. Thomas Peterffy and his affiliates, management and other employees of IBG LLC, and certain other members. The IBG LLC membership interests held by Holdings will be subject to purchase by us over time in connection with offerings by us of shares of our common stock. Business Segments We report our results in two operating business segments, electronic brokerage and market making. These segments are analyzed separately as these are the two principal business activities from which we derive our revenues and to which we allocate resources. (cid:129) Electronic Brokerage. We conduct our electronic brokerage business through certain IB subsidiaries. As an electronic broker, we execute, clear and settle trades globally for both institutional and individual customers. Capitalizing on the technology originally developed for our market making business, IB’s systems provide our customers with the capability to monitor multiple markets around the world simultaneously and to execute trades electronically in these markets at a low cost, in multiple products and currencies from a single trading account. We offer our customers access to all classes of tradable, primarily exchange-listed products, including stocks, bonds, options, futures, forex and mutual funds traded on more than 100 exchanges and market centers in 24 countries and in 23 currencies around the world seamlessly. The emerging complexity of multiple market centers has provided us with the opportunity of building and continuously adapting our order routing software to secure excellent execution prices. 44 Our customer base is diverse with respect to geography and segments. Currently, more than half of our customers reside outside the U.S. in over 190 countries. Approximately 64% of our customers’ equity is in institutional accounts which include hedge funds, financial advisors, proprietary trading desks, and introducing brokers. We have developed specialized products and services that are successfully attracting these accounts. For examples, we offer prime brokerage services, including capital introduction and securities lending to hedge funds; and our model portfolio technology and automated share allocation and rebalancing tools are particularly attractive to financial advisors. We provide a host of analytical tools such as the Probability LabSM, which allows our customers to analyze option strategies under various market assumptions. The IB Investors’ MarketplaceSM allows wealth advisors to search for money managers and assign them to client accounts based on their investment strategy. IB EmployeeTrackSM is widely used by compliance officers of financial institutions to streamline the process of tracking their employees’ brokerage activities. Portfolio Builder allows our customers to set up an investment strategy based on research and rankings from top buy-side providers and fundamental data. In addition, RIA Compliance Center provides information to assist advisors with registration and compliance obligations. (cid:129) Market Making. We conduct our market making business primarily through our TH subsidiaries. As one of the largest market makers on many of the world’s leading exchanges, we provide liquidity by offering competitively tight bid/offer spreads over a broad base of over one million tradable, exchange-listed products. As principal, we commit our own capital and derive revenues or incur losses from the difference between the price paid when securities are bought and the price received when those securities are sold. Because we provide continuous bid and offer quotations and we are continuously both buying and selling quoted securities, we may have either a long or a short position in a particular product at a given point in time. Our entire portfolio is evaluated each second and continuously rebalanced throughout the trading day, thus minimizing the risk of our portfolio at all times. This real-time rebalancing of our portfolio, together with our real-time proprietary risk management system, enables us to curtail risk and to be profitable in both up-market and down-market scenarios. In the past several years our market making business has suffered from competitive pressures and along with the rapid increase of our electronic brokerage business, its significance has diminished. The operating business segments are supported by our corporate segment which provides centralized services and executes our currency diversification strategy. Business Environment The operating environment for our brokerage business continued to exhibit positive trends in 2015. Investor uncertainty accompanied a downdraft in the equity markets in the third quarter of 2015, and a period of increased volatility led to a contraction of margin borrowings but higher trading volumes. We maintained our position as the largest U.S. electronic broker as measured by number of customer revenue trades, which increased 14% over the prior year, driving a 12% increase in commissions and execution fees. New customer account growth continued to gain momentum as total customer accounts increased 18% to 331 thousand in 2015. Institutional customers, such as hedge funds, mutual funds, introducing brokers, proprietary trading groups and financial advisors, comprised approximately 44% of total accounts and approximately 64% of total customer equity at the end of 2015. Our customer base continues to be geographically diversified, as our customers reside in over 190 countries and over 50% of new customers came from outside the U.S. Average equity per account increased by 1%, to $204 thousand as of December 31, 2015. 45 Customers continued to take advantage of our low margin lending rates, which are tied to benchmark rates, such as the Federal Funds rate in the U.S. In 2015, our customers paid 0.5% to 1.86% for their U.S. dollar margin loans with us. After building steadily for a number of years, customer margin loans increased by only 1% from 2014, as customers responded to the volatile markets by reducing their leverage. In spite of the modest growth in customer margin loans, electronic brokerage net interest income grew 24% in 2015, because average customer credit balances and margin loans for the year were up 18% and 10%, respectively. Market making segment results increased in 2015 driven by higher market volatility and periods of higher trading activity. The following is a summary of the key profit drivers that affect our business and how they compared to the prior year: Global trading volumes. According to data received from exchanges worldwide, volumes in exchange- listed equity-based options increased by approximately 10% globally and decreased 3% in the U.S. for the year ended December 31, 2015, compared to 2014. During 2015 (2014) we accounted for approximately 7.8% (8.5%) of the exchange-listed equity-based options (including options on ETFs and stock index products) volume traded worldwide and approximately 11.3% (11.2%) of exchange-listed equity-based options volume traded in the U.S. It is important to note that this metric is not directly correlated with our profits. See the tables on pages 59-60 of this Annual Report on Form 10-K for additional details regarding our trade volumes, contract and share volumes and brokerage statistics. Volatility. Our market making profits are generally correlated with market volatility since we typically maintain an overall long volatility position, which protects us against a severe market dislocation in either direction. Based on the Chicago Board Options Exchange Volatility Index (‘‘VIX(cid:4)’’), the average volatility increased to 16.7 in 2015, an increase of 18% from the average of 14.2 in 2014. The ratio of actual to implied volatility is also meaningful to our results. Because the cost of hedging our positions is based on implied volatility, while our trading profits are, in part, based on actual market volatility, a higher ratio is generally favorable and a lower ratio generally has a negative effect on our trading gains. This ratio averaged approximately 88% during 2015, compared to an average of 79% in 2014, rising above 100% during the third quarter of 2015 for the first time since the third quarter of 2011. Currency fluctuations. As a global electronic broker and market maker trading on exchanges around the world in multiple currencies, we are exposed to foreign currency risk. We actively manage this exposure by keeping our net worth in proportion to a defined basket of 16 currencies we call the ‘‘GLOBAL’’ in order to diversify our risk and to align our hedging strategy with the currencies that we use in our business. Because we report our financial results in U.S. dollars, the change in the value of the GLOBAL to the U.S. dollar affects our earnings. The value of the GLOBAL, as measured in U.S. dollars, as of December 31, 2015 declined 5% compared to its value as of December 31, 2014. This decline had a negative impact on our comprehensive earnings in 2015. A discussion of our approach for managing foreign currency exposure is contained in Part II, Item 7A of this Annual Report on Form 10-K entitled ‘‘Quantitative and Qualitative Disclosures about Market Risk.’’ Financial Overview Diluted earnings per share were $0.78 for the year ended December 31, 2015 (‘‘current year’’), compared to diluted earnings per share of $0.77 for the year ended December 31, 2014 (‘‘prior year’’). The calculation of diluted earnings per share is detailed in Note 4 to the audited consolidated financial statements, in Part II, Item 8 of this Annual Report on Form 10-K. 46 On a comprehensive basis, which includes other comprehensive income (‘‘OCI’’), diluted earnings per share were $0.62 for the current year, compared to diluted earnings per share of $0.51 for the prior year. In connection with our currency diversification strategy, we have determined to base our net worth in GLOBALs, a basket of 16 major currencies in which we hold our equity. As a result, as of December 31, 2015, approximately 57% of our equity was denominated in currencies other than U.S. dollar. In the current year, our currency diversification strategy decreased our comprehensive earnings by $269 million ($293 million in the prior year), as the U.S. dollar value of the GLOBAL decreased by approximately 5%. The effects of our currency diversification strategy are reported as (1) a component of other income in the consolidated statement of comprehensive income and (2) OCI in the consolidated statement of financial condition and the consolidated statement of comprehensive income. The full effect of the GLOBAL is captured in comprehensive income. Consolidated: For the current year, our net revenues were $1,189 million and income before income taxes was $458 million, compared to net revenues of $1,043 million and income before income taxes of $506 million in the prior year. The decrease in income before income taxes was mainly driven by customer bad debt expenses, which increased $143 million primarily driven by the Swiss franc event described below; employee compensation and benefits expenses, which increased 11%; and execution and clearing expenses, which increased 9%; partially offset by net interest income, which increased 24%; and commission and execution fees, which increased 12%, in the current year. Our pre-tax profit margin was 39% for the current year and 49% for the prior year. Electronic Brokerage: For the current year, income before income taxes in our electronic brokerage segment decreased $53 million, or 9%, compared to the prior year, mainly driven by customer bad debt expenses, which increased $143 million primarily driven by the Swiss franc event described below. Net revenues increased 15%, mainly due to higher commissions and execution fees, which increased 13%, on higher customer trade volumes, and higher net interest income, which increased 24%, driven by higher average customer margin borrowings and higher customer cash balances. Pre-tax profit margin was 49% for the current year and 62% for the prior year. Customer accounts grew 18% and customer equity increased 19% from the prior year. Total Daily Average Revenue Trades (‘‘DARTs’’) for cleared and execution-only customers, for the current year, increased 14% to 647 thousand, compared to 566 thousand in the prior year. Sudden Move in the Value of the Swiss Franc On January 15, 2015, due to the sudden move in the value of the Swiss Franc that followed an unprecedented action by the Swiss National Bank, which removed a previously instituted and repeatedly confirmed cap of the currency relative to the Euro, several of our customers who held currency futures and spot positions suffered losses in excess of their deposits with us. We took immediate action to hedge its exposure to the foreign currency receivables from these customers. During the current year, we incurred losses, net of hedging activity and debt collection efforts, of $119 million. We continue to actively pursue collection of the debts. The ultimate effect of this incident on our results will depend upon the outcome of our debt collection efforts. Market Making: For the current year, income before income taxes in our market making segment increased $16 million, or 14%, compared to the prior year, as trading gains were favorably impacted by higher volatility levels and periods of higher trading activity. Pre-tax profit margin was 44% for the current year and 40% for the prior year. 47 Market making, by its nature, does not produce predictable earnings. Our results in any given period may be materially affected by volumes in the global financial markets, the level of competition and other factors. Electronic brokerage is more predictable, but it is dependent on customer activity, growth in customer accounts and assets, interest rates and other factors. For a further discussion of the factors, that may affect our future operating results, please see the description of risk factors in Part I, Item 1A of this Annual Report on Form 10-K. The following two tables present net revenues and income before income taxes for each of our business segments for the periods indicated.

Net Revenues Trading Gains Trading gains are generated in the normal course of our market making business. Trading revenues are, in general, proportional to the trading activity in the markets. Our revenue base is highly diversified and comprised of millions of relatively small individual trades of various financial products traded on electronic exchanges, primarily in stocks, options and futures. Trading gains accounted for approximately 23%, 25% and 31% of our total net revenues for the years ended December 31, 2015, 2014 and 2013, respectively. 48 Trading gains also include revenues from net dividends. Market making activities require us to hold a substantial inventory of equity securities. We derive significant revenues in the form of dividend income from these equity securities. This dividend income is largely offset by dividend expense incurred when we make significant payments in lieu of dividends on short positions in securities in our portfolio. Dividend income and expense arise from holding market making positions over dates on which dividends are paid to shareholders of record. When a stock pays a dividend, its market price is generally adjusted downward to reflect the value paid to the shareholders of record, which will not be received by those who purchase the stock after the dividend date. Hence, the apparent gains and losses due to these price changes must be taken together with the dividends paid and received, respectively, to accurately reflect the results of our market making operations. As a result of the way we have integrated our market making and securities lending systems, our trading gains and our net interest income from the market making segment are interchangeable and depend on the mix of market making positions in our portfolio. When implied interest rates in the equity and equity options and futures markets exceed the actual interest rates available to us, our market making systems tend to buy stock and sell it forward, which produces higher trading gains and lower net interest income. When these rates are inverted, our market making systems tend to sell stock and buy it forward, which produces lower trading gains and higher net interest income. Our trading gains are geographically diversified. In 2015, 2014 and 2013, we generated 59%, 24% and 41%, respectively, of our trading gains from operations conducted internationally. Commissions and Execution Fees We earn commissions and execution fees from our cleared customers for whom we act as an executing and clearing broker and from our non-cleared customers for whom we act as an execution-only broker. We have a commission structure that allows customers to choose between an all-inclusive ‘‘bundled’’ rate or an ‘‘unbundled’’ rate that offers lower commissions for high volume customers. For ‘‘unbundled’’ commissions, we charge regulatory and exchange fees, at our cost, separately from our commissions, adding transparency to our fee structure. Commissions and execution fees accounted for 52%, 53% and 47% of our total net revenues for the years ended December 31, 2015, 2014 and 2013, respectively. Our commissions and execution fees are geographically diversified. In 2015, 2014 and 2013 we generated 26%, 25% and 26%, respectively, of commissions and execution fees from operations conducted internationally. Interest Income and Interest Expense We earn interest on customer funds segregated in safekeeping accounts; on customer borrowings on margin, secured by marketable securities these customers hold with us; from our investment in U.S. and foreign government securities; from borrowing and lending securities in the general course of our market making and brokerage activities; and on deposits with banks. Interest income accounted for 41%, 40% and 28% of our total net revenues for the years ended December 31, 2015, 2014 and 2013, respectively. Interest income is partially offset by interest expense. We pay interest on cash balances customers hold with us; for borrowing and lending securities in the general course of our market making and brokerage activities; and on our borrowings. Interest expense accounted for 6%, 7% and 5% of our total net revenues for the years ended December 31, 2015, 2014 and 2013, respectively. We have automated and integrated our securities lending system with our trading system. As a result, we have been able to tailor our securities lending activity to produce more optimal results when taken together with trading gains (see description under ‘‘Trading Gains’’ above). 49 Net interest income accounted for approximately 36%, 33% and 23% of our total net revenues for the years ended December 31, 2015, 2014 and 2013, respectively. Other Income The largest component of other income is foreign currency gains and losses from our currency diversification strategy. A discussion of our approach to managing foreign currency exposure is contained in Part II, Item 7A of this Annual Report on Form 10-K entitled ‘‘Quantitative and Qualitative Disclosures about Market Risk.’’ Other income also consists of market data fee income, payments for order flow income, minimum activity fee, risk exposure fee income, and gains and losses on financial instruments at fair value and other financial instruments that are not held for our market making operations. Other income (loss) accounted for approximately (cid:5)10%, (cid:5)11% and (cid:5)1% of our total net revenues for the years ended December 31, 2015, 2014 and 2013, respectively. Costs and Expenses Execution and Clearing Expenses Execution and clearing expenses include the costs of executing and clearing our market making and electronic brokerage trades, as well as other direct expenses, including regulatory fees, market data fees and payments for order flow. Execution fees are paid primarily to electronic exchanges and market centers on which we trade. Clearing fees are paid to clearing houses and clearing agents. Market data fees are paid to third parties to receive streaming price quotes and related information. Payments for order flow are paid as part of exchange-mandated programs and to otherwise attract order volume to our system. Employee Compensation and Benefits Employee compensation and benefits include salaries, bonuses and other incentive compensation plans, group insurance, contributions to benefit programs and other related employee costs. Occupancy, Depreciation and Amortization Occupancy expenses consist primarily of rental payments on office and data center leases and related occupancy costs, such as utilities. Depreciation and amortization expenses result from the depreciation of fixed assets, such as computing and communications hardware, as well as amortization of leasehold improvements, capitalized in-house software development and acquired intangible assets. Communications Communications expenses consist primarily of the cost of voice and data telecommunications lines supporting our business, including connectivity to exchanges around the world. General and Administrative and Customer Bad Debt General and administrative expenses consist primarily of professional services expenses, such as legal and audit work, and other operating expenses such as advertising and exchange membership lease expenses. Customer bad debt expenses consist primarily of losses incurred by customers in excess of their assets with us, net of amounts recovered by us. 50 Income Tax Expense We pay U.S. federal, state and local income taxes on our taxable income, which is proportional to the percentage we own of IBG LLC. Also, our subsidiaries are subject to income tax in the respective jurisdictions in which they operate. Noncontrolling Interest We are the sole managing member of IBG LLC and, as such, operate and control all of the business and affairs of IBG LLC and its subsidiaries and consolidate IBG LLC’s financial results into our financial statements. As of December 31, 2015, we held approximately 15.7% ownership interest in IBG LLC. Holdings is owned by the original members of IBG LLC and holds approximately 84.3% ownership interest in IBG LLC. We reflect Holdings’ ownership as a noncontrolling interest in our consolidated statement of financial condition, consolidated statement of comprehensive income, consolidated statement of changes in equity and consolidated statement of cash flows. Our share of IBG LLC’s net income, excluding Holdings’ noncontrolling interest, for the current year was approximately 15.1%, compared to approximately 14% for the prior year. Certain Trends and Uncertainties We believe that our continuing operations may be favorably or unfavorably impacted by the following trends that may affect our financial condition and results of operations. (cid:129) Over the past several years, the effects of market structure changes, competition (in particular, from HFTs) and market conditions have, during certain periods, exerted downward pressure on bid/offer spreads realized by market makers. (cid:129) Retail broker-dealer participation in the equity markets has fluctuated over the past few years due to investor sentiment, market conditions and a variety of other factors. Retail transaction volumes may not be sustainable and are not predictable. (cid:129) In recent years, in an effort to improve the quality of their executions as well as increase efficiencies, market makers have increased the level of automation within their operations, which may allow them to compete more effectively with us. (cid:129) Scrutiny of equity and option market makers, hedge funds and soft dollar practices by regulatory and legislative authorities has increased. New legislation or modifications to existing regulations and rules could occur in the future. (cid:129) Additional consolidation among market centers may adversely affect the value of our smart routing software. (cid:129) A driver of our market making profits is the relationship between actual and implied volatility in the equities markets. The cost of maintaining our conservative risk profile is based on implied volatility, while our profitability, in part, is based on actual volatility. Hence, our profitability is increased when actual volatility runs above implied volatility and it is decreased when actual volatility falls below implied volatility. Implied volatility tends to lag actual volatility. See ‘‘Risk Factors’’ in Part I, Item 1A of this Annual Report on Form 10-K for a discussion of other risks that may affect our financial condition and results of operations. 51 Results of Operations The tables in the period comparisons below provide summaries of our consolidated results of operations.

The increase in net revenues was primarily due to higher commissions and execution fees and net interest income. Trading volume is an important driver of revenues and costs for both our electronic brokerage and market making segments. During the current year, our futures contract and stock share volumes increased 14% and 12%, respectively, while options contract volume remained unchanged, compared to the prior year. Trading Gains Trading gains, for the current year, increased $8 million, or 3%, to $269 million, compared to the prior year. As market makers, we provide liquidity by buying from sellers and selling to buyers. During the current year, our market making operations executed 65.9 million trades, an increase of 2% compared to the number of trades executed in the prior year. Market making stock share volume increased 28%, while options and futures contract volumes decreased 3% and 4%, respectively, compared to the prior year. 53 Trading gains were favorably impacted by higher volatility levels and periods of higher trading activity. The VIX(cid:4), which measures perceived U.S. equity market volatility, increased 18% to an average of 16.7 for the current year, compared to an average of 14.2 for the prior year. The ratio of actual to implied volatility increased to an average of 88% for the current year, compared to an average of 79% for the prior year. Included in trading gains are net dividends. Dividend income and expense arise from holding market making positions over dates on which dividends are paid to shareholders of record. When a stock pays a dividend, its market price is generally adjusted downward to reflect the value paid, which will not be received by those who purchase stock after the ex-dividend date. Hence, the apparent gains and losses due to these price changes, reflecting the value of dividends paid to shareholders, must be taken together with the dividends paid and received, respectively, to accurately reflect the results of our market making operations. Commissions and Execution Fees Commissions and execution fees, for the current year, increased $68 million, or 12%, to $617 million, compared to the prior year, driven by continued customer account growth and increased customer trading activity, but moderated by lower average commission per customer order. Cleared customer options and futures contract volumes and stock share volume increased 8%, 17% and 12%, respectively, from the prior year. Total DARTs for cleared and execution-only customers, for the current year, increased 14% to 647 thousand, compared to 566 thousand during the prior year. DARTs for cleared customers, i.e., customers for whom we execute trades, as well as, clear and carry positions, for the current year, increased 14% to 589 thousand, compared to 515 thousand for the prior year. Average commission per DART for cleared customers, for the current year, decreased by 2% to $4.07, compared to $4.16 for the prior year. Interest Income and Interest Expense Net interest income (interest income less interest expense), for the current year, increased $81 million, or 24%, to $425 million, compared to the prior year. The increase in net interest income was driven by higher average customer margin borrowings, higher average customer cash balances which were invested in interest-bearing instruments (e.g., U.S. government securities), and higher net fees earned from securities lending transactions. Net interest income on customer balances, for the current year, increased $66 million, compared to the prior year, driven by a $5.0 billion increase in average customer cash balances, which were invested in interest-bearing instruments (e.g., U.S. government securities), and a $1.6 billion increase in average customer margin borrowings. In addition, the average Fed Funds effective rate increased by approximately four basis points to 0.13% for the current year, compared to the prior year. We earn fees on securities loaned and borrowed to support customer long and short stock holdings in margin accounts. In addition, our Stock Yield Enhancement Program provides an opportunity for customers with fully-paid stock to allow us to lend it out. In exchange for lending out their stock, our customers receive generally 50% of the stock loan fees. We place cash collateral securing the loans in the customer’s account. In the market making segment, as a result of the way we have integrated our market making and securities lending systems, our trading income and our net interest income are interchangeable and depend on the mix of market making positions in our portfolio. When implied interest rates in the equity and equity options and futures markets exceed the actual interest rates available to us, our market making systems tend to buy stock and sell it forward, which produces higher trading gains and lower net interest income. When these rates are inverted, our market making systems tend to sell stock and buy it forward, which produces lower trading gains and higher net interest income. 54 In the current year, average securities borrowed increased by 10%, to $3.5 billion and average securities loaned increased by 2%, to $3.0 billion, compared to the prior year. Net interest earned from securities lending is also affected by the level of demand for securities positions in our market making business and held by our customers. During the current year, net fees earned by our electronic brokerage and market making segments from securities lending transactions increased $16 million, or 12%, compared to the prior year. The majority of the increase in net interest income from securities lending transactions was attributable to the electronic brokerage segment. Other Income Other income, for the current year, decreased $11 million, or 10%, to a loss of $122 million, compared to the prior year, mainly driven by $21 million higher losses on our currency diversification strategy and $36 million higher mark-to-market losses on U.S. government securities, partially offset by $15 million higher risk exposure fee income and an $18 million gain from our hedging activities to offset our losses related to the Swiss franc event. In general, mark-to-market gains and losses on U.S. government securities are expected to reverse when, as intended, these securities are held to maturity. A discussion of our approach to managing foreign currency exposure is contained in Part II, Item 7A of this Annual Report on Form 10-K entitled ‘‘Quantitative and Qualitative Disclosures about Market Risk.’’ Non-Interest Expenses Non-interest expenses, for the current year, increased $194 million, or 36%, to $731 million, compared to the prior year, mainly due to higher customer bad debt expense due to the Swiss franc event, execution and clearing expenses, and employee compensation and benefits expenses. As a percentage of total net revenues, non-interest expenses were 61% for the current year and 51% for the prior year. Execution and Clearing Execution and clearing expenses, for the current year, increased $19 million, or 9%, to $231 million, compared to the prior year, driven by higher trading volumes in options, futures and stocks in the electronic brokerage segment and higher trading volumes in stocks in the market making segment. Employee Compensation and Benefits Employee compensation and benefits expenses, for the current year, increased $22 million, or 11%, to $227 million, compared to the prior year, mainly due to a 13% increase in the number of employees to 1,087, compared to 960 for the prior year. Approximately 15% of the increase in the number of employees was due to the acquisition of Covestor, an online investment marketplace, during the second quarter of the current year. Within the operating business segments, we continued to add staff in electronic brokerage and reduce staff in market making. As we continue to grow, our focus on automation has allowed us to maintain a relatively small staff. As a percentage of total net revenues, employee compensation and benefits expenses were 19% for the current year and 20% for the prior year. Occupancy, Depreciation and Amortization Occupancy, depreciation and amortization expenses, for the current year, increased $5 million, or 13%, to $44 million, compared to the prior year, mainly due to higher amortization expenses as a result of acquired intangible assets during the current year. As a percentage of total net revenues, occupancy, depreciation and amortization expenses were 4% for both the current year and the prior year. 55 Communications Communications expenses, for the current year, increased $1 million, or 4%, to $25 million, compared to the prior year. As a percentage of total net revenues, communications expenses were 2% for both the current year and the prior year. General and Administrative General and administrative expenses, for the current year, increased $4 million, or 7%, to $58 million, compared to the prior year, mainly due to higher advertising expenses. As a percentage of total net revenues, general and administrative expenses were 5% for both the current year and the prior year. Customer Bad Debt Customer bad debt expense, for the current year, increased $143 million, to $146 million, compared to the prior year, primarily due to unsecured customer losses of $137 million caused by the sudden move in the value of the Swiss franc, as described above in the ‘‘Financial Overview’’ section, and $7 million caused by the market volatility in the late-August period. Income Tax Expense Income tax expense, for the current year, decreased $4 million, or 9%, to $43 million, compared to the prior year, as income before taxes decreased $48 million, or 9%, during the same period. Our operating results, for the current year, excluding the effects of our currency diversification strategy and the Swiss franc related customer losses, compared to the prior year were as follows: net revenues were $1,377 million, up 10%; non-interest expenses were $594 million, up 11%; income before income taxes was $783 million, up 10%; and pre-tax profit margin was 57% for both the current year and the prior year. Year Ended December 31, 2014 compared to the Year Ended December 31, 2013 Net Revenues Total net revenues, in 2014, decreased $33 million, or 3%, to $1,043 million, compared to 2013. The decrease in net revenues was primarily due to lower trading gains and higher losses on our currency diversification strategy, partially offset by increases in net interest income and commissions and execution fees. Trading volume is an important driver of revenues and costs for both our electronic brokerage and market making segments. In 2014, our options contract volume decreased 4%, while futures contract and stock share volumes increased 1% and 61%, respectively, compared to 2013. Trading Gains Trading gains, in 2014, decreased $70 million, or 21%, to $261 million, compared to 2013. As market makers, we provide liquidity by buying from sellers and selling to buyers. In 2014, our market making operations executed 64.5 million trades, a decrease of 1% compared to the number of trades executed in 2013. Market making options and futures contract and stock share volumes decreased 15%, 14% and 6%, respectively, compared to 2013. Trading gains were negatively impacted by a market making environment with intense competition and low volatility levels. The VIX(cid:4), which measures perceived U.S. equity market volatility, remained unchanged at an average of 14.2 in 2014, compared to 2013. The ratio of actual to implied volatility was up slightly to an average of 79% in 2014, compared to an average of 77% in 2013. An approximate $16 million loss due to a trading error in the third quarter of 2014, also negatively impacted trading gains. 56 Included in trading gains are net dividends. Dividend income and expense arise from holding market making positions over dates on which dividends are paid to shareholders of record. When a stock pays a dividend, its market price is generally adjusted downward to reflect the value paid, which will not be received by those who purchase stock after the ex-dividend date. Hence, the apparent gains and losses due to these price changes, reflecting the value of dividends paid to shareholders, must be taken together with the dividends paid and received, respectively, to accurately reflect the results of our market making operations. Commissions and Execution Fees Commissions and execution fees, in 2014, increased $47 million, or 9%, to $549 million, compared to 2013, driven by continued customer account growth and increased customer trading activity, but moderated by lower commissions per customer order. Cleared customer options and futures contract volumes and stock share volume increased 25%, 4% and 74%, respectively, from 2013. Total DARTs for cleared and execution-only customers, in 2014, increased 16% to 566 thousand, compared to 486 thousand in 2013. DARTs for cleared customers, i.e., customers for whom we execute trades as well as clear and carry positions, in 2014, increased 17% to 515 thousand, compared to 441 thousand in 2013. Average commission per DART for cleared customers, in 2014, decreased by 6% to $4.16, compared to $4.41 in 2013. Interest Income and Interest Expense Net interest income (interest income less interest expense), in 2014, increased $92 million, or 37%, to $344 million, compared to 2013. The increase in net interest income was driven by higher average customer margin borrowings, higher average customer cash balances which were invested in interest- bearing instruments (e.g., U.S. government securities), and higher net fees earned from securities lending transactions. Net interest income on customer balances, in 2014, increased $43 million, compared to 2013, driven by a $4.7 billion increase in average customer cash balances, which were invested in mainly interest- bearing instruments (e.g., U.S. government securities), and a $4.3 billion increase in average customer margin borrowings, but moderated by a lower average Fed Funds effective rate, which decreased by approximately two basis points to 0.09% in 2014, compared to 2013. We earn fees on securities loaned and borrowed to support customer long and short stock holdings in margin accounts. In addition, our Stock Yield Enhancement Program provides an opportunity for customers with fully-paid stock to allow us to lend it out. In exchange for lending out their stock, our customers receive generally 50% of the stock loan fees. We place cash collateral securing the loans in the customer’s account. In the market making segment, as a result of the way we have integrated our market making and securities lending systems, our trading income and our net interest income are interchangeable and depend on the mix of market making positions in our portfolio. When implied interest rates in the equity and equity options and futures markets exceed the actual interest rates available to us, our market making systems tend to buy stock and sell it forward, which produces higher trading gains and lower net interest income. When these rates are inverted, our market making systems tend to sell stock and buy it forward, which produces lower trading gains and higher net interest income. 57 In 2014, average securities borrowed decreased by 8%, to $3.2 billion, and average securities loaned increased by 34%, to $2.9 billion, compared to 2013. Net interest earned from securities lending is also affected by the level of demand for securities positions in our market making business and held by our customers. In 2014, net fees earned by our electronic brokerage and market making segments from securities lending transactions increased $47 million, or 49%, compared to 2013. The majority of the increase in net interest from securities lending transactions was attributable to the electronic brokerage segment. Other Income Other income, in 2014, decreased $102 million, to a loss of $111 million, compared to 2013, mainly driven by $94 million higher losses on our currency diversification strategy, lower market data fee income, higher losses on other investments and lower dividend income from investments; partially offset by higher risk exposure fee income. A discussion of our approach to managing foreign currency exposure is contained in Part II, Item 7A of this Annual Report on Form 10-K entitled ‘‘Quantitative and Qualitative Disclosures about Market Risk.’’ Non-Interest Expenses Non-interest expenses, in 2014, decreased $88 million, or 14%, to $537 million, compared to 2013, mainly due to lower execution and clearing fees and general and administrative expenses. As a percentage of total net revenues, non-interest expenses were 51% for 2014 and 58% for 2013. Execution and Clearing Execution and clearing expenses, in 2014, decreased $31 million, or 13%, to $212 million, compared to 2013, driven by lower overall trading volumes in options and an increase in our executions on exchanges and ECN’s with make-or-take revenue models, under which we are paid for providing liquidity. Employee Compensation and Benefits Employee compensation and benefits expenses, in 2014 were $205 million, unchanged from 2013. The number of employees increased 9% to 960 in 2014, compared to 880 in 2013, resulting in higher compensation expense, which was offset by lower benefits expense. Within the operating segments, we continued to add staff in electronic brokerage and reduce staff in market making. As we continue to grow, our focus on automation has allowed us to maintain a relatively small staff. As a percentage of total net revenues, employee compensation and benefits expenses were 20% for 2014 and 19% for 2013. Occupancy, Depreciation and Amortization Occupancy, depreciation and amortization expenses, in 2014 and 2013, were $39 million. As a percentage of total net revenues, occupancy, depreciation and amortization expenses were 4% for both 2014 and 2013. Communications Communications expenses, in 2014, increased $1 million, or 4%, to $24 million, compared to 2013. As a percentage of total net revenues, communications expenses were 2% for both 2014 and 2013. 58 General and Administrative General and administrative expenses, in 2014, increased $6 million, or 13%, to $54 million, compared to 2013, mainly due to higher advertising and professional services expenses. As a percentage of total net revenues, general and administrative expenses were 5% for both 2014 and 2013. Customer bad debt Customer bad debt expense, in 2014, decreased $64 million, to $3 million, compared to 2013, mainly due to the non-recurrence of customer bad debt recognized in 2013 related to the Singapore stock issue discussed below. In October 2013, a small number of our brokerage customers had taken relatively large positions in four securities listed on the Singapore Exchange. In early October 2013, within a very short timeframe, these securities lost over 90% of their value. The customer accounts were margined and fell into deficits totaling $64 million prior to the time we took possession of their securities positions. Income Tax Expense Income tax expense, in 2014, increased $14 million, or 42%, to $47 million, compared to 2013, while income before taxes increased $55 million, or 12%, during the same period. The increase in income tax expense is due to additional amortization of the deferred tax asset arising from the step-up in tax basis of our interests in IBG LLC, as a result of the 2013 and 2014 membership interest redemptions from Holdings. In addition, in 2013, we recognized greater tax benefits related to prior years, than in 2014. Supplemental Information The following tables present historical trading volumes for our business.

Business Segments The following sections discuss the results of our operations by business segment, excluding a discussion of corporate segment income and expense. In the following tables, revenues and expenses directly associated with each business segment are included in determining income before income taxes. Due to the integrated nature of the business segments, estimates and judgments have been made in allocating certain revenue and expense items. Transactions between business segments generally result from one subsidiary facilitating the business of another subsidiary through the use of its existing trading memberships and clearing arrangements. In such cases, certain revenue and expense items are eliminated to accurately reflect the external business conducted in each business segment. Rates on transactions between business segments are designed to approximate full costs. In addition to execution and clearing expenses, which are the main cost driver for both the market making and the electronic brokerage segments, each business segment’s operating expenses include: (i) employee compensation and benefits expenses that are incurred directly in support of each business segment, (ii) general and administrative expenses, which include directly incurred expenses for property leases, professional fees, travel and entertainment, communications and information services, equipment, and (iii) indirect support costs (including compensation and other related operating expenses) for administrative services provided by IBG LLC. Such administrative services include, but are not limited to, computer software development and support, accounting, tax, legal and facilities management. 61 Electronic Brokerage The following table sets forth the results of our electronic brokerage operations for the indicated periods: Year Ended December 31, 2015 2014 2013 (in millions) Revenues Commissions and execution fees . . . . . . . . . . . . . . . . . . . .

Commissions and execution fees, for the current year, increased $69 million, or 13%, to $618 million, compared to the prior year, driven by continued customer account growth and increased customer trading activity, but moderated by lower average commission per customer order. Cleared customer options and futures contract volumes and stock share volume increased 8%, 17% and 12%, respectively, from the prior year. Total DARTs for cleared and execution-only customers, for the current year, increased 14% to 647 thousand, compared to 566 thousand during the prior year. DARTs for cleared customers, i.e., customers for whom we execute trades, as well as, clear and carry positions, for the current year, increased 14% to 589 thousand, compared to 515 thousand for the prior year. Average commission per DART for cleared customers, for the current year, decreased by 2% to $4.07, compared to $4.16 for the prior year. Net interest income, for the current year, increased $78 million, or 24%, to $400 million, compared to the prior year. The increase in net interest income was attributable to higher net customer interest of $66 million, driven by a $5.0 billion increase in average customer cash balances, which were invested in interest-bearing instruments (e.g., U.S. government securities), and a $1.6 billion increase in average customer margin borrowings, and higher net fees from securities lending transactions of $14 million. In addition, the average Fed Funds effective rate increased by approximately four basis points to 0.13% for the current year, compared to the prior year. Other income, for the current year, decreased $2 million, or 2%, to $79 million, compared to the prior year, mainly due to $36 million higher mark-to-market losses on U.S. government securities, largely offset 62 by $15 million higher risk exposure fee income and an $18 million gain from our hedging activities to offset our losses related to the Swiss franc event. In general, mark-to-market gains and losses on U.S. government securities are expected to reverse when, as intended, these securities are held to maturity. Non-interest expenses, for the current year, increased $198 million, or 55%, to $561 million, compared to the prior year, mainly due to $137 million bad debt expense as a result of the sudden move in the value of the Swiss franc as described above in the ‘‘Financial Overview’’ section, and $7 million bad debt expense caused by the market volatility in the late-August period. Within non-interest expenses, execution and clearing expenses increased $12 million, or 8%, due to higher trading volume across all product classes. Employee compensation and benefits expenses increased $17 million, or 21%, due to a 13% increase in the average number of employees. General and administrative expenses increased $20 million, or 18%, primarily due to higher administrative, consulting and advertising expenses. As a percentage of total net revenues, non-interest expenses were 51% for the current year and 38% for the prior year. Income before income taxes, for the current year, decreased $53 million, or 9%, to $536 million, compared to the prior year. As a percentage of total net revenues for the electronic brokerage segment, income before income taxes was 49% for the current year and 62% for the prior year. Electronic brokerage segment’s operating results, for the current year, excluding the effects of the Swiss franc related customer losses, compared to the prior year were as follows: net revenues were $1,079 million, up 13%; non-interest expenses were $424 million, up 17%; income before income taxes was $655 million, up 11%; and pre-tax profit margin was 61% for the current year and 62% for the prior year. Year Ended December 31, 2014 compared to the Year Ended December 31, 2013 Electronic brokerage total net revenues, in 2014, increased $133 million, or 16%, to $952 million, compared to 2013, primarily due to higher net interest income and commission and execution fees. Commissions and execution fees, in 2014, increased $47 million, or 9%, to $549 million, compared to 2013, driven by continued customer account growth and increased customer trading activity, but moderated by lower commissions per customer order. Cleared customer options and futures contract volumes and stock share volume increased 25%, 4% and 74%, respectively, from 2013. Total DARTs for cleared and execution-only customers, in 2014, increased 16% to 566 thousand, compared to 486 thousand in 2013. DARTs for cleared customers, i.e., customers for whom we execute trades as well as clear and carry positions, in 2014, increased 17% to 515 thousand, compared to 441 thousand in 2013. Average commission per DART for cleared customers, in 2014, decreased by 6% to $4.16, compared to $4.41 in 2013. Net interest income, in 2014, increased $90 million, or 39%, to $322 million, compared to 2013. The increase in net interest income was attributable to higher net customer interest of $43 million, driven by a $4.7 billion increase in average customer cash balances, which were invested in mainly interest- bearing instruments (e.g., U.S. government securities) and a $4.3 billion increase in average customer margin borrowings, and higher net fees from securities lending transactions of $46 million. The increase in net interest income was moderated by a lower average Fed Funds effective rate, which decreased by approximately two basis points to 0.09% in 2014, compared to 2013. Non-interest expenses, in 2014, decreased $60 million, or 14%, to $363 million, compared to 2013, mainly due to lower customer bad debt expense, which decreased as a result of the non-recurrence of a $64 million bad debt expense recorded in 2013 related to the Singapore stock issue discussed above. Within non-interest expenses, execution and clearing expenses decreased $11 million, or 7%, due to continued price competition between U.S. stock and options exchanges. Employee compensation and benefits expenses increased $6 million, or 8%, due to an 11% increase in the average number of employees. General and administrative expenses increased $10 million, or 10%, primarily due to higher professional services and other administrative expenses. As a percentage of total net revenues, non-interest expenses were 38% in 2014 and 52% in 2013. Income before income taxes, in 2014, increased $193 million, or 49%, to $589 million, compared to 2013. As a percentage of total net revenues for the electronic brokerage segment, income before income taxes was 62% in 2014 and 48% in 2013. 63 Market Making The following table sets forth the results of our market making operations for the indicated periods: Revenues Trading gains . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Trading gains, for the current year, increased $8 million, or 3%, to $269 million, compared to the prior year. Trading gains were favorably impacted by higher volatility levels and periods of higher trading activity. The VIX(cid:4), which measures perceived U.S. equity market volatility, increased 18% to an average of 16.7 for the current year, compared to an average of 14.2 for the prior year. The ratio of actual to implied volatility increased to an average of 88% for the current year, compared to an average of 79% for the prior year. Stock share volume increased 28%, while options and futures contract volumes decreased 3% and 4%, respectively, compared to the prior year. Net interest income, for the current year, decreased $2 million, or 10%, to $19 million, compared to the prior year. As described above, our trading gains and our net interest income are interchangeable and depend on the mix of market making positions in our portfolio and on relative interest rates in the stock and options markets. In the current year, these factors, together with a reduction in interest earned on deposits with banks, produced less net interest income than in the prior year. Non-interest expenses, for the current year, decreased $2 million, or 1%, to $168 million, compared to the prior year. The decrease was primarily due to a $6 million decrease in general and administrative expenses driven by lower administrative and consulting fees, primarily for internal software development, and a $3 million decrease in employee compensation and benefits expenses as reductions in staff in the market making segment continued; partially offset by an $8 million increase in execution and clearing driven by higher trading volumes. As a percentage of total net revenues, non-interest expenses were 56% for the current year and 60% for the prior year. 64 Income before income taxes, for the current year, increased $16 million, or 14%, to $130 million, compared to the prior year. As a percentage of total net revenues for the market making segment, income before income taxes was 44% for the current year and 40% for the prior year. Year Ended December 31, 2014 compared to the Year Ended December 31, 2013 Market making total net revenues, in 2014, decreased $77 million, or 21%, to $284 million, compared to 2013, primarily due to lower trading gains. Trading gains, in 2014, decreased $71 million, or 21%, to $261 million, compared to 2013. Trading gains were negatively impacted by a market making environment with intense competition and low volatility levels. The VIX(cid:4), which measures perceived U.S. equity market volatility, remained unchanged at an average of 14.2 in 2014, compared to 2013. The ratio of actual to implied volatility was up slightly to an average of 79% in 2014, compared to an average of 77% in 2013. An approximate $16 million loss due to a trading error in the third quarter of 2014 also negatively impacted trading gains. Options and futures contract and stock share volumes decreased 15%, 14% and 6%, respectively, compared to 2013. Net interest income, in 2014, decreased by $1 million, or 5%, to $21 million, compared to 2013. As described earlier, our trading gains and our net interest income are interchangeable and depend on the mix of market making positions in our portfolio and on relative interest rates in the stock and options markets. In 2014, these factors, together with lower securities lending activity, produced less net interest income than in 2013. Non-interest expenses, in 2014, decreased $32 million, or 16%, to $170 million, compared to 2013. The decrease was primarily due to a $20 million decrease in execution and clearing fees driven by lower volumes across all product classes; and a $7 million decrease in general and administrative expenses driven by lower administrative and consulting fees, primarily for internal software development. As a percentage of total net revenues, non-interest expenses were 60% for 2014 and 56% for 2013. Income before income taxes, in 2014, decreased $45 million, or 28%, to $114 million, compared to 2013. As a percentage of total net revenues for the market making segment, income before income taxes was 40% for 2014 and 44% for 2013. Liquidity and Capital Resources We maintain a highly liquid balance sheet. The majority of our assets consist of investments of customer funds, collateralized receivables arising from customer-related and proprietary securities transactions, and exchange-listed marketable securities, which are marked-to-market daily. Collateralized receivables consist primarily of customer margin loans, securities borrowed, and, to a lesser extent receivables from clearing houses for settlement of securities transactions, and securities purchased under agreements to resell. As of December 31, 2015, total assets were $48.7 billion of which approximately $48.3 billion, or 99.2% were considered liquid. Daily monitoring of liquidity needs and available collateral levels is undertaken to help ensure that an appropriate liquidity cushion, in the form of unpledged collateral, is maintained at all times. Our ability to quickly reduce funding needs by balance sheet contraction without adversely affecting our core businesses and to pledge additional collateral in support of secured borrowings is continuously evaluated to ascertain the adequacy of our capital base. We actively manage our excess liquidity and we maintain significant borrowing facilities through the securities lending markets and with banks. As a general practice, we maintain sufficient levels of cash on hand to provide us with a buffer should we need immediately available funds for any reason. Liability balances, as of December 31, 2015, in connection with our short-term borrowings, securities loaned and payables to customers were lower than their respective average monthly balances during the 65 year ended December 31, 2015. Based on our current level of operations, we believe our cash flows from operations, available cash and available borrowings will be adequate to meet our future liquidity needs for more than the next twelve months. Cash and cash equivalents held by our non-U.S. operating companies as of December 31, 2015 were $382 million ($440 million as of December 31, 2014). These funds are primarily intended to finance each individual operating company’s local operations, and thus would not be available to fund U.S. domestic operations unless repatriated through payment of dividends to IBG LLC. In December 2015, a dividend of $80 million was paid to IBG LLC from a non-U.S. subsidiary. We currently have no intention to repatriate further amounts from non-U.S. operating companies. In the event dividends were to be paid to the Company in the future by a non-U.S. operating company, the Company would be required to accrue and pay income taxes on such dividends to the extent that U.S. income taxes had not been paid previously on the income of the paying company. Historically, our consolidated equity has consisted primarily of accumulated retained earnings, which to date have been sufficient to fund our operations and growth. Our consolidated equity increased 3% to $5.3 billion as of December 31, 2015 from $5.2 billion as of December 31, 2014. This is attributable to total comprehensive income for 2015, offset by distributions and dividends paid during 2015. Cash Flows The following table sets forth our cash flows from operating activities, investing activities and financing activities for the periods indicated: Net cash provided by operating activities . . . . . . . . . . . . . . . . . . Net cash provided by (used in) investing activities . . . . . . . . . . . . Net cash used in financing activities . . . . . . . . . . . . . . . . . . . . .

Our cash flows from investing activities are primarily related to other investments, capitalized internal software development, purchases and sales of memberships at exchanges where we trade, and strategic investments where such investments may enable us to offer better execution alternatives to our current and prospective customers, or create new opportunities for ourselves as market makers or where we can influence exchanges to provide competing products at better prices using sophisticated technology. Our cash flows from financing activities are comprised of short-term borrowings and capital transactions. Short-term borrowings from banks are part of our daily cash management in support of operating activities. Capital transactions consist primarily of the quarterly dividends beginning in June 2011 and continuing through December 2015 paid to common stockholders, and related cash distributions paid to Holdings. Year Ended December 31, 2015: Our cash and cash equivalents increased by $332 million to $1,601 million at the end of 2015. We raised $725 million in net cash from operating activities. We used net cash of $330 million in our investing and financing activities, primarily for dividends paid to our common stockholders, distributions to noncontrolling interests and payments made to Holdings under the Tax Receivable Agreement. Under investing activities, purchases and sales of other investments mainly consisted of transactions in marketable securities held for investment purposes. 66 Year Ended December 31, 2014: Our cash and cash equivalents increased by $56 million to $1,269 million at the end of 2014. We raised $417 million in net cash from operating activities. We used net cash of $254 million in our investing and financing activities, primarily for dividends paid to our common stockholders, distributions to noncontrolling interests and payments made to Holdings under the Tax Receivable Agreement. Under investing activities, purchases and sales of other investments mainly consisted of transactions in marketable securities held for investment purposes. Year Ended December 31, 2013: Our cash and cash equivalents decreased by $168 million to $1,213 million at the end of 2013. We raised $140 million in net cash from operating activities. We used net cash of $33 million in our investing activities to purchase other investments and for capital expenditures. We used $248 million in financing activities, primarily for dividends paid to our common stockholders, distributions to noncontrolling interest and to reduce short-term borrowings. Regulatory Capital Requirements Our principal operating subsidiaries are subject to separate regulation and capital requirements in the U.S. and other jurisdictions. IB LLC and TH LLC are registered U.S. broker-dealers and their primary regulators include the SEC, the CFTC, the Chicago Board Options Exchange, the Chicago Mercantile Exchange and FINRA. IB LLC is also a registered U.S. futures commission merchant, as such it is regulated by the NFA. THE is registered to do business in Switzerland as a securities dealer and is regulated by the Swiss Financial Market Supervisory Authority. IBUK is subject to regulation by the U.K. Financial Conduct Authority. Our various other operating subsidiaries are similarly regulated. See the notes to the consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K for further information regarding our regulated subsidiaries. As of December 31, 2015, aggregate excess regulatory capital for all of the operating companies was $3.4 billion, and all of the operating companies were in compliance with their respective regulatory capital requirements.

This credit facility replaced a similar two-year facility that expired on May 18, 2012. On August 8, 2014 IBG LLC elected to terminate this credit facility. Capital Expenditures Our capital expenditures are comprised of compensation costs of our software engineering staff for development of software for internal use and expenditures for computer, networking and communications hardware. These expenditure items are reported as property and equipment. Capital expenditures for property, equipment and intangible assets were approximately $30 million, $19 million and $17 million for the three years ended December 31, 2015, 2014 and 2013, respectively. In the 67 future, we plan meet capital expenditure needs as we continue our focus on technology infrastructure initiatives to further enhance our competitive position. We anticipate that we will fund capital expenditures with cash from operations and cash on hand. In response to changing economic conditions, we believe we have the flexibility to modify our capital expenditures by adjusting them (either upward or downward) to match our actual performance. If we pursue any strategic acquisitions, we may incur additional capital expenditures.

Through December 31, 2015, approximately $99 million of cumulative cash payments have been made. Seasonality Our businesses are subject to seasonal fluctuations, reflecting varying numbers of market participants at times during the year and varying numbers of trading days from quarter-to-quarter, including declines in trading activity due to holidays. Typical seasonal trends may be superseded by market or world events, which can have a significant impact on prices and trading volume. Inflation Although we cannot accurately anticipate the effect of inflation on our operations, we believe that, for the three most recent years, inflation has not had a material impact on our results of operations and will not likely have a material impact in the foreseeable future. Investments in U.S. government securities We invest in U.S. government securities for the purpose of satisfying U.S. regulatory requirements. Sudden increases in interest rates will cause mark-to-market losses on these securities which are recovered if we hold them to maturity, as currently intended. The impact of changes in interest rates is further described in ITEM 7A of this Annual Report on Form 10-K entitled ‘‘Quantitative and Qualitative Disclosures about Market Risk.’’ Strategic Investments and Acquisitions We regularly evaluate potential strategic investments and acquisitions. We hold strategic investments in electronic trading exchanges including: Boston Options Exchange, LLC; OneChicago LLC and CBOE Stock Exchange, LLC. We intend to continue making acquisitions on an opportunistic basis, generally only when the acquisition candidate will, in our opinion, enable us to acquire either technology or customers faster 68 than we could develop them on our own. In May 2015, we completed the acquisition of Covestor, Inc., an online investing marketplace and an investment advisor registered with the SEC. Covestor is a pioneer in the online investing business and the first digital asset management company to offer both active and passive investment options. The acquisition solidifies and expands our position as the leading platform for electronic trading and investing by creating a marketplace that brings investors, wealth managers and money managers together. This acquisition will enable us to further refine our platform to provide a more complete service to ‘‘robo-advisor’’ companies in general. As of December 31, 2015, there were no definitive agreements with respect to any material acquisition. Certain Information Concerning Off-Balance-Sheet Arrangements We may be exposed to a risk of loss not reflected in the consolidated financial statements for futures products, which represent our obligations to settle at contracted prices, which may require us to repurchase or sell in the market at prevailing prices. Accordingly, these transactions result in off-balance sheet risk as our cost to liquidate such futures contracts may exceed the amounts reported in our consolidated statements of financial condition. Critical Accounting Policies Principles of Consolidation, including Noncontrolling Interests The consolidated financial statements include the accounts of IBG, Inc. and its majority and wholly owned subsidiaries. As sole managing member of IBG LLC, we exert control over the Group’s operations. In accordance with Financial Accounting Standards Board (‘‘FASB’’) Accounting Standards Codification (‘‘ASC’’) ASC Topic 810, ‘‘Consolidation’’, we consolidate the Group’s consolidated financial statements and record as noncontrolling interest the interests in the Group that we do not own. We are the sole managing member of IBG LLC and, as such, operate and control all of the business and affairs of IBG LLC and its subsidiaries and as such, consolidate IBG LLC’s financial results into our financial statements. We hold approximately 15.7% ownership interest in IBG LLC. Holdings is owned by the original members of IBG LLC and holds approximately 84.3% ownership interest in IBG LLC. Our current share of IBG LLC’s net income is approximately 15.7%. Our policy is to consolidate all other entities in which we own more than 50% unless we do not have control. All inter-company balances and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in the consolidated financial statements and accompanying notes. These estimates and assumptions are based on judgment and the best available information at the time. Therefore, actual results could differ materially from those estimates. Such estimates include the allowance for doubtful accounts, valuation of certain investments, compensation accruals, current and deferred income taxes, and contingency reserves. Valuation of Financial Instruments Due to the nature of our operations, substantially all of our financial instrument assets, comprised of financial instruments owned, securities purchased under agreements to resell, securities borrowed, receivable from customers, and receivables from brokers, dealers and clearing organizations are carried at fair value based on published market prices and are marked to market daily, or are assets which are short-term in nature and are reported at amounts that approximate fair value. Similarly, all of our financial instrument liabilities that arise from financial instruments sold but not yet purchased, 69 securities sold under agreements to repurchase, securities loaned, payables to customers, and payables to brokers, dealers and clearing organizations are carried at fair value based on published market prices and are marked to market daily, or are liabilities which are short-term in nature and are reported at amounts that approximate fair value. Our long and short positions are mainly valued at the last consolidated trade price at the close of regular trading hours, in their respective markets. Given that we manage a globally integrated market making portfolio, we have large and substantially offsetting positions in securities and commodities that trade on different exchanges that close at different times of the trading day. As a result, there may be large and anomalous swings in the value of our positions daily and, accordingly, in our earnings in any period. This is especially true on the last business day of each calendar quarter or year, although such swings tend to come back into equilibrium on the first business day of the succeeding calendar quarter or year. Earnings per Share Earnings per share (‘‘EPS’’) are computed in accordance with FASB ASC Topic 260, ‘‘Earnings per Share.’’ Basic EPS is computed by dividing the net income available for common stockholders by the weighted average number of shares outstanding for that period. Diluted EPS is calculated by dividing the net income available for common stockholders by the diluted weighted average shares outstanding for that period. Diluted EPS includes the determinants of the basic EPS and, in addition, reflects the dilutive effect of shares of common stock estimated to be distributed in the future under our stock- based compensation plans, with no adjustments to net income available for common stockholders for dilutive potential common shares. Stock-Based Compensation We follow FASB ASC Topic 718, ‘‘Compensation—Stock Compensation’’ (‘‘ASC Topic 718’’), to account for our stock-based compensation plans. ASC Topic 718 requires all share-based payments to employees to be recognized in the consolidated financial statements using a fair value-based method. Grants, which are denominated in U.S. dollars, are communicated to employees in the year of grant, thereby establishing the fair value of each grant. The fair value of awards granted to employees are generally expensed as follows: 50% in the year of grant in recognition of plan forfeiture provisions (described below) and the remaining 50% over the related vesting period utilizing the ‘‘graded vesting’’ method permitted under ASC Topic 718. In the case of ‘‘retirement eligible’’ employees (those employees older than 59), 100% of awards are expensed when granted. Awards granted under the stock-based compensation plans are subject to forfeiture in the event an employee ceases employment with us. The plans provide that employees who discontinue employment with us without cause and continue to meet the terms of the plans’ post-employment provisions will forfeit 50% of unvested previously granted awards unless the employee is over the age of 59, in which case the employee would be eligible to receive 100% of unvested awards previously granted. Contingencies Our policy is to estimate and accrue for potential losses that may arise out of litigation and regulatory proceedings, to the extent that such losses are probable and can be estimated, in accordance with FASB ASC Topic 450, ‘‘Contingencies.’’ Significant judgment is required in making these estimates and our final liabilities may ultimately be materially different. Our total liability accrued with respect to litigation and regulatory proceedings is determined on a case-by-case basis and represents an estimate of probable losses based on, among other factors, the progress of each case, our experience with and industry experience with similar cases and the opinions and views of internal and external legal counsel. Given the inherent difficulty of predicting the outcome of our litigation and regulatory matters, particularly in cases or proceedings in which substantial or indeterminate damages or fines are sought, 70 or where cases or proceedings are in the early stages, we cannot estimate losses or ranges of losses for cases or proceedings where there is only a reasonable possibility that a loss may be incurred. We have been from time to time subject to certain pending and legal actions which arise out of the normal course of business. Litigation is inherently unpredictable, particularly in proceedings where claimants seek substantial or indeterminate damages, or which are in their early stages. We cannot predict with certainty the actual loss or range of loss related to such legal proceedings, the manner in which they will be resolved, the timing of final resolution or the ultimate settlement. Consequently, we cannot estimate losses or ranges of losses related to such legal matters, even in instances where it is reasonably possible that a future loss will be incurred. As of December 31, 2015, we, along with certain of our subsidiaries, have been named parties to legal actions, which we and/or such subsidiaries intend to defend vigorously. Although the results of legal actions cannot be predicted with certainty, it is the opinion of management that the resolution of these actions is not expected to have a material adverse effect, if any, on our business or financial condition, but may have a material impact on the results of operations for a given period. As of December 31, 2015 and December 31, 2014, reserves provided for potential losses related to litigation matters were not material. Income Taxes We account for income taxes in accordance with FASB ASC Topic 740, ‘‘Income Taxes’’ (‘‘ASC Topic 740’’). Our income tax expense, deferred tax assets and liabilities, and reserves for unrecognized tax benefits are based on enacted tax laws and reflect management’s best assessment of estimated future taxes to be paid. We are subject to income taxes in both the U.S. and numerous foreign jurisdictions. Determining income tax expense requires significant judgments and estimates. We recognize interest related to income tax matters as interest income or interest expense and penalties related to income tax matters as income tax expense. Deferred income tax assets and liabilities arise from temporary differences between the tax and financial statement recognition of the underlying assets and liabilities. In evaluating our ability to recover our deferred tax assets within the jurisdictions from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, historical results are adjusted for changes in accounting policies and incorporate assumptions including the amount of future state, federal and foreign pre-tax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax-planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, three years of cumulative operating income (loss) are considered. Deferred income taxes have not been provided for U.S. tax liabilities or for additional foreign taxes on the unremitted earnings of foreign subsidiaries that have been indefinitely reinvested. The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across our global operations. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Management is not aware of any such changes that would have a material effect on our results of operations, cash flows, or financial position. We recognize that a tax benefit from an uncertain tax position may be recognized only when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits. A tax position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement. 71 We record tax liabilities in accordance with ASC Topic 740 and adjust these liabilities when management’s judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in payments that are different from the current estimates of these tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information becomes available.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK We are exposed to various market risks. Our exposures to market risks arise from assumptions built into our pricing models, equity price risk, foreign currency exchange rate fluctuations related to our international operations, changes in interest rates which impact our variable-rate debt obligations, if any, and risks relating to the extension of margin credit to our customers. Market risk refers to the risk that a change in the level of one or more market prices, rates, indices, implied volatilities (the price volatility of the underlying instrument imputed from option prices), correlations or other market factors, such as market liquidity, will result in losses for a position or portfolio. Generally, we incur trading-related market risk as a result of activities in the market making segment, where the substantial majority of our Value-at-Risk (‘‘VaR’’) for market risk exposures is generated. In addition, we incur non-trading-related market risk primarily from investment activities and from foreign currency exposure held in the equity of our foreign affiliates, i.e., our non-U.S. brokerage affiliates and information technology affiliates, and held to meet target balances in our currency diversification strategy. We use various risk management tools in managing our market risk, which are embedded in our real-time market making systems. We employ certain hedging and risk management techniques to protect us from a severe market dislocation. Our risk management policies are developed and implemented by our Chairman and our steering committee, which is comprised of senior executives of our various companies. Our strategy is to calculate quotes a few seconds ahead of the market and execute small trades at a tiny but favorable differential as a result. This is made possible by our proprietary pricing model, which evaluates and monitors the risks inherent in our portfolio, assimilates market data and reevaluates the outstanding quotes in our portfolio each second. Our model automatically rebalances our positions throughout each trading day to manage risk exposures on our options and futures positions and the underlying securities, and will price the increased risk that a position would add to the overall portfolio into the bid and offer prices we post. Under risk management policies implemented and monitored primarily through our computer systems, reports to management, including risk profiles, profit and loss analysis and trading performance, are prepared on a real-time basis as well as daily and periodical bases. Although our market making is completely automated, the trading process and our risk are monitored by a team of individuals who, in real time, observe various risk parameters of our consolidated positions. Our assets and liabilities are marked-to-market daily for financial reporting purposes and re-valued continuously throughout the trading day for risk management and asset/liability management purposes. We use a covariant VaR methodology to measure, monitor and review the market risk of our market making portfolios, with the exception of fixed income products, and our currency exposures. The risk of fixed income products, which comprise primarily U.S. government securities, is measured using a stress test. Pricing Model Exposure As described above, our proprietary pricing model, which continuously evaluates and monitors the risks inherent in our portfolio, assimilates market data and reevaluates the outstanding quotes in our entire portfolio each second. Certain aspects of the model rely on historical prices of securities. If the behavior of price movements of individual securities diverges substantially from what their historical behavior would predict, we might incur trading losses. We attempt to limit such risks by diversifying our portfolio across many different options, futures and underlying securities and avoiding concentrations of positions based on the same underlying security. Historically, our losses from these events have been immaterial in comparison to our annual trading profits. 73 Foreign Currency Exposure As a result of our international market making activities and accumulated earnings in our foreign subsidiaries, our income and net worth is exposed to fluctuations in foreign exchange rates. Our European operations and some of our Asian operations are conducted by our Swiss subsidiary, THE. THE is regulated by the Swiss Financial Market Supervisory Authority as a securities dealer and its financial statements are presented in Swiss francs. Accordingly, THE is exposed to certain foreign exchange risks as described below: (cid:129) THE buys and sells futures contracts and securities denominated in various currencies and carries bank balances and borrows and lends such currencies in its regular course of business. At the end of each accounting period THE’s assets and liabilities are translated into Swiss francs for presentation in its financial statements. The resulting gains or losses are reported as translation gain or loss in THE’s income statement. When we prepare our consolidated financial statements, THE’s Swiss franc balances are translated into U.S. dollars for U.S. GAAP purposes. THE’s translation gains or losses appear as such on our consolidated statement of comprehensive income, as a component of other income. (cid:129) THE’s net worth is carried on THE’s books in Swiss francs in accordance with Swiss accounting standards. At the end of each accounting period, THE’s net worth is translated at the then prevailing exchange rate into U.S. dollars and the resulting gain or loss is reported as OCI in our consolidated statement of financial condition and consolidated statement of comprehensive income. To a smaller extent, OCI is also produced by our other non-U.S. subsidiaries. Historically, we have taken the approach of not hedging the above exposures, based on the notion that the cost of constantly hedging over the years would amount to more than the random impact of rate changes on our non-U.S. dollar balances. For instance, an increase in the value of the Swiss franc would be unfavorable to the earnings of THE but would be counterbalanced to some extent by the fact that the yearly translation gain or loss into U.S. dollars is likely to move in the opposite direction. Our market making systems incorporate cash forex and forex options to hedge our currency exposure at little or no cost throughout each day on a continuous basis. The majority of currency spot positions held as part of our currency diversification strategy are regularly transferred from the market making unit to the parent holding company, IBG LLC, where they are held and reported in the corporate segment. In connection with the development of our currency diversification strategy, we determined to base our net worth in GLOBALs, a basket of currencies. Periodically, we re-evaluate the composition of the GLOBAL; in 2011 we expanded the composition of the GLOBAL from six to 16 currencies. The 74 table below shows a comparison of the U.S. dollar equivalent of the GLOBAL as of December 31, 2015 and 2014. As of 12/31/2014 As of 12/31/2015 Currency USD . . . . EUR . . . . JPY . . . . .

The U.S. dollar value of the GLOBAL decreased from $1.01 to $ 0.96, or 5%, as of December 31, 2015 compared to December 31, 2014. As of December 31, 2015, approximately 57% of our equity was denominated in currencies other than the U.S. dollar. The effects of our currency diversification strategy appear in two places in the consolidated financial statements: (1) as a component of other income in the consolidated statement of comprehensive income and (2) as OCI in the consolidated statement of financial condition and the consolidated statement of comprehensive income. The full effect of the GLOBAL is captured in the consolidated statement of comprehensive income. Reported results on a comprehensive basis reflect the U.S. GAAP convention that requires the reporting of currency translation results contained in OCI as part of reportable earnings. Interest Rate Risk We had no variable-rate debt outstanding as of December 31, 2015. We pay our electronic brokerage customers interest based on benchmark overnight interest rates in various currencies, on balances above $10 thousand, or equivalent, and on accounts holding more than $100 thousand (or equivalent) net asset value. In a normal rate environment, we typically invest a portion of these funds in U.S. government securities with maturities of up to two years. If interest rates were to increase rapidly and substantially, our net interest income will not increase proportionally with the interest rates, for the portion of the funds invested in the U.S. government securities with fixed yields. In addition, the mark-to-market changes in the value of these fixed rate securities will be reflected in other income, instead of net interest income. Based on customer balances and investments outstanding as of December 31, 2015, an increase of 0.5% in the U.S. benchmark interest rates over two quarters would result in a net increase in our net interest income of approximately $47 million on an annualized basis. If the benchmark rates were to increase by 1.0% over four quarters from current 75 levels, our net interest income would increase by approximately $36 million on an annualized basis. We do not approximate mark-to-market impact from interest rate changes; if U.S. government securities whose prices were to fall under these scenarios were held to maturity, as intended, then the reduction in net interest income would be temporary, as the securities would mature at par value. We also face the potential for reduced net interest income from customer deposits due to interest rate spread compression in a low rate environment. A decrease of the benchmark interest rates by 0.25%, would reduce our net interest income by approximately $24 million on an annualized basis. We also face substantial interest rate risk due to positions carried in our market making business to the extent that long or short stock positions may have been established for future or forward dates on options or futures contracts and the value of such positions are impacted by interest rates. We hedge such risks by entering into interest rate futures contracts. To the extent that these futures positions do not perfectly hedge this interest rate risk, our trading gains may be adversely affected. The amount of such risk cannot be quantified. Dividend Risk We face dividend risk in our market making business as we derive significant revenues and incur significant expenses in the form of dividend income and expense, respectively, from our substantial inventory of equity securities, and must make significant payments in lieu of dividends on short positions in equity securities within our portfolio. Projected future dividends are an important component of pricing equity options and other derivatives, and incorrect projections may lead to trading losses. The amount of such risk cannot be quantified. Margin Credit We extend margin credit to our customers, which is subject to various regulatory requirements. Margin credit is collateralized by cash and securities in the customers’ accounts. The risks associated with margin credit increase during periods of fast market movements or in cases where collateral is concentrated and market movements occur. During such times, customers who utilize margin credit and who have collateralized their obligations with securities may find that the securities have a rapidly depreciating value and may not be sufficient to cover their obligations in the event of a liquidation. We are also exposed to credit risk when our customers execute transactions, such as short sales of options and equities that can expose them to risk beyond their invested capital. We expect this kind of exposure to increase with the growth of our overall business. Because we indemnify and hold harmless our clearing firms from certain liabilities or claims, the use of margin credit and short sales may expose us to significant off-balance-sheet risk in the event that collateral requirements are not sufficient to fully cover losses that customers may incur and those customers fail to satisfy their obligations. As of December 31, 2015, we had $17.0 billion in margin credit extended to our customers. The amount of risk to which we are exposed from the margin credit we extend to our customers and from short sale transactions by our customers is unlimited and not quantifiable as the risk is dependent upon analysis of a potential significant and undeterminable rise or fall in stock prices. Our account level margin credit requirements meet or exceed those required by Regulation T of the Board of Governors of the Federal Reserve and SEC portfolio margin rules, as applicable. As a matter of practice, we enforce real-time margin compliance monitoring and liquidate customers’ positions if their equity falls below required margin requirements. We have a comprehensive policy implemented in accordance with regulatory standards to assess and monitor the suitability of investors to engage in various trading activities. To mitigate our risk, we also continuously monitor customer accounts to detect excessive concentration, large orders or positions, patterns of day trading and other activities that indicate increased risk to us. 76 Our credit exposure is to a great extent mitigated by our policy of automatically evaluating each account throughout the trading day and closing out positions automatically for accounts that are found to be under-margined. While this methodology is effective in most situations, it may not be effective in situations where no liquid market exists for the relevant securities or commodities or where, for any reason, automatic liquidation for certain accounts has been disabled. Value-at-Risk We estimate VaR using an historical approach, which uses the historical daily price returns of underlying assets as well as estimates of the end of day implied volatility for options. Our one-day VaR is defined as the unrealized loss in portfolio value that, based on historically observed market risk factors, would have been exceeded with a frequency of one percent, based on a calculation with a confidence interval of 99%. Our VaR model generally takes into account exposures to equity and commodity price risk and foreign exchange rates. We use VaR as one of a range of risk management tools. Among their benefits, VaR models permit estimation of a portfolio’s aggregate market risk exposure, incorporating a range of varied market risks and portfolio assets. One key element of the VaR model is that it reflects risk reduction due to portfolio diversification or hedging activities. However, VaR has various strengths and limitations, which include, but are not limited to: use of historical changes in market risk factors, which may not be accurate predictors of future market conditions, and may not fully incorporate the risk of extreme market events that are outsized relative to observed historical market behavior or reflect the historical distribution of results beyond the confidence interval; and reporting of losses in a single day, which does not reflect the risk of positions that cannot be liquidated or hedged in one day. A small proportion of market risk generated by trading positions is not included in VaR. The modeling of the risk characteristics of some positions relies on approximations that, under certain circumstances, could produce significantly different results from those produced using more precise measures. VaR is most appropriate as a risk measure for trading positions in liquid financial markets and will understate the risk associated with severe events, such as periods of extreme illiquidity. The VaR calculation simulates the performance of the portfolio based on several years of the daily price changes of the underlying assets and determines the VaR as the calculated loss that occurs at the 99th percentile. Since the reported VaR statistics are estimates based on historical data, VaR should not be viewed as predictive of our future revenues or financial performance or of our ability to monitor and manage risk. There can be no assurance that our actual losses on a particular day will not exceed the indicated VaR or that such losses will not occur more than one time in 100 trading days. VaR does not predict the magnitude of losses which, should they occur, may be significantly greater than the VaR amount. Stress Test We estimate the market risk of our fixed income portfolio using a risk analysis model provided by a leading external vendor. For corporate bonds, this stress test is configured to calculate the change in value of each fixed income security in the portfolio over one day in seven scenarios each of which represents a parallel shift of the U.S. Treasury yield curve. The scenarios are shifts of +/(cid:5)100, +/(cid:5)200 and +/(cid:5)300 basis points. For U.S. government securities, the stress test is configured to calculate the change in value of each fixed income security in the portfolio over one day in three scenarios each of which represents a parallel shift of the U.S. Treasury yield curve. The scenarios are shifts of +/(cid:5)25 basis points. 77 VaR and Stress Test Measures Market Risk Category Trading(1) At December 31, 2015 At December 31, 2014 Average High 2015 2015 (in millions) Equities and Currencies(2) . . . . . . .

The ‘‘Non-trading’’ category reflects investment activities and foreign currency exposures held in the equity of the Company’s non-market making affiliates, i.e., its brokerage affiliates and information technology affiliates. This category also includes corporate segment activities in foreign exchange designed to achieve the Company’s currency diversification strategy. The average and high VaR and stress test amounts are based on the four quarter ending calculations performed in 2015. (2) Equities and currencies held for market making purposes are combined because these products are part of an integrated, hedged market making portfolio, on which the risk is measured using VaR. (3) The Trading—Fixed Income category contains primarily foreign government securities held in connection with market making activities and, as of December 31, 2014, a small value of corporate bonds. The risks on these products were managed separately and measured using the stress test analysis. (4) The Non-Trading—Fixed Income, Other category contains primarily U.S. government securities held in segregated safekeeping accounts for the exclusive benefit of our brokerage customers, on which the risk is measured using a stress test analysis. The amount as of December 31, 2014 has been revised to be consistent with this presentation. 78 ITEM 8.

Greenwich, CT We have audited the accompanying consolidated statements of financial condition of Interactive Brokers Group, Inc. and subsidiaries (the ‘‘Company’’) as of December 31, 2015 and 2014, and the related consolidated statements of comprehensive income, changes in equity, and cash flows for each of the three years in the period ended December 31, 2015. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Interactive Brokers Group, Inc. and subsidiaries as of December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2015, based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2016 expressed an unqualified opinion on the Company’s internal control over financial reporting. /s/ Deloitte & Touche LLP New York, New York February 26, 2016 80 Interactive Brokers Group, Inc. and Subsidiaries Consolidated Statements of Financial Condition (in millions, except share amounts) Assets Cash and cash equivalents . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Significant Accounting Policies Basis of Presentation These consolidated financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the U.S. (‘‘U.S. GAAP’’) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (‘‘SEC’’) regarding financial reporting with respect to Form 10-K. 85 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 2. Significant Accounting Policies (Continued) These consolidated financial statements include the accounts of the Company and its consolidated subsidiaries and reflect all adjustments of a normal and recurring nature that are, in the opinion of management, necessary for the fair presentation of the results for the periods presented. In the third quarter of 2015, the Company changed the presentation of its non-market making financial instruments carried at fair value from other assets and accounts payable, accrued expenses and other liabilities to financial instruments owned, at fair value and financial instruments sold, but not yet purchased, at fair value, respectively, in the consolidated statements of financial condition, in order to consistently present all of the financial instruments held for trading under the same caption. For comparison purposes, as of December 31, 2014, $44 million was reclassified from other assets to financial instruments owned, at fair value, and $8 million was reclassified from accounts payable, accrued expenses and other liabilities to financial instruments sold, but not yet purchased, at fair value. Principles of Consolidation, including Noncontrolling Interests The consolidated financial statements include the accounts of IBG, Inc. and its majority and wholly owned subsidiaries. As sole managing member of IBG LLC, IBG, Inc. exerts control over IBG LLC’s operations. In accordance with Financial Accounting Standards Board (‘‘FASB’’) Accounting Standards Codification (‘‘ASC’’) Topic 810, ‘‘Consolidation,’’ the Company consolidates IBG LLC’s financial statements and records the interests in IBG LLC that it does not own as noncontrolling interests. The Company’s policy is to consolidate all other entities in which it owns more than 50% unless it does not have control. All inter-company balances and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in these consolidated financial statements and accompanying notes. These estimates and assumptions are based on judgment and the best available information at the time. Therefore, actual results could differ materially from those estimates. Such estimates include the allowance for doubtful accounts, valuation of certain investments, compensation accruals, current and deferred income taxes, and contingency reserves. Fair Value Substantially all of the Company’s assets and liabilities, including financial instruments are carried at fair value based on published market prices and are marked to market, or are assets and liabilities which are short-term in nature and are carried at amounts that approximate fair value. 86 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 2. Significant Accounting Policies (Continued) The Company applies the fair value hierarchy in accordance with FASB ASC Topic 820, ‘‘Fair Value Measurement’’ (‘‘ASC Topic 820’’), to prioritize the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable inputs. The three levels of the fair value hierarchy are: Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 Quoted prices in markets that are not considered to be active or financial instruments for which all significant inputs are observable, either directly or indirectly. Level 3 Prices or valuations that require inputs that are both significant to fair value measurement and unobservable. Financial instruments owned, at fair value and financial instruments sold, but not yet purchased, at fair value are generally classified as Level 1 of the fair value hierarchy. The Company’s Level 1 financial instruments, which are valued using quoted market prices as published by exchanges and clearing houses or otherwise broadly distributed in active markets, include active listed stocks, options, warrants and discount certificates, and U.S. and foreign government securities. The Company does not adjust quoted prices for financial instruments classified as Level 1 of the fair value hierarchy, even in the event that the Company may hold a large position whereby a purchase or sale could reasonably impact quoted prices. Currency forward contracts are valued using broadly distributed bank and broker prices, and are classified as Level 2 of the fair value hierarchy as such instruments are not exchange-traded. Other securities that are not traded in active markets are also classified in Level 2 of the fair value hierarchy. Level 3 financial instruments are comprised of securities that have been delisted or otherwise are no longer tradable and have been valued by the Company based on internal estimates. Earnings Per Share Earnings per share (‘‘EPS’’) is computed in accordance with FASB ASC Topic 260, ‘‘Earnings per Share.’’ Basic EPS is computed by dividing the net income available for common stockholders by the weighted average number of shares outstanding for that period. Diluted EPS is calculated by dividing the net income available for common stockholders by the diluted weighted average shares outstanding for that period. Diluted EPS includes the determinants of the basic EPS and, in addition, reflects the dilutive effect of shares of common stock estimated to be distributed in the future under the Company’s stock-based compensation plans, with no adjustments to net income available for common stockholders for dilutive potential common shares. 87 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 2. Significant Accounting Policies (Continued) Stock-Based Compensation The Company follows FASB ASC Topic 718, ‘‘Compensation—Stock Compensation’’ (‘‘ASC Topic 718’’), to account for its stock-based compensation plans. ASC Topic 718 requires all share-based payments to employees to be recognized in the consolidated financial statements using a fair value- based method. Grants, which are denominated in U.S. dollars, are communicated to employees in the year of grant, thereby establishing the fair value of each grant. The fair value of awards granted to employees are generally expensed as follows: 50% in the year of grant in recognition of plan forfeiture provisions (as described below) and the remaining 50% over the related vesting period utilizing the ‘‘graded vesting’’ method permitted under ASC Topic 718. In the case of ‘‘retirement eligible’’ employees (those employees older than 59), 100% of awards are expensed when granted. Awards granted under stock-based compensation plans are subject to forfeiture in the event an employee ceases employment with the Company. The plans provide that employees who discontinue employment with the Company without cause and continue to meet the terms of the plans’ post-employment provisions will forfeit 50% of unvested previously granted awards unless the employee is over the age of 59, in which case the employee would be eligible to receive 100% of unvested awards previously granted. Cash and Cash Equivalents Cash and cash equivalents consist of deposits with banks and all highly liquid investments, with maturities of three months or less, that are not segregated and deposited for regulatory purposes or to meet margin requirements at clearing houses. Cash and Securities—Segregated for Regulatory Purposes As a result of customer activities, certain Operating Companies are obligated by rules mandated by their primary regulators to segregate or set aside cash or qualified securities to satisfy such regulations, which have been promulgated to protect customer assets. Securities segregated for regulatory purposes consisted of U.S. government securities of $15.2 billion and $6.7 billion as of December 31, 2015 and December 31, 2014, respectively, and securities purchased under agreements to resell in the amount of $0.6 billion and $3.9 billion as of December 31, 2015 and December 31, 2014, respectively, which amounts approximate fair value. Securities Borrowed and Securities Loaned Securities borrowed and securities loaned are recorded at the amount of the cash collateral advanced or received. Securities borrowed transactions require the Company to provide counterparties with collateral, which may be in the form of cash, letters of credit or other securities. With respect to securities loaned, the Company receives collateral, which may be in the form of cash or other securities in an amount generally in excess of the fair value of the securities loaned. The Company monitors the market value of securities borrowed and loaned on a daily basis, with additional collateral obtained or refunded as permitted contractually. The Company does not net, in the consolidated statements of financial condition, securities borrowed and securities loaned entered into with the same counterparty that do not meet the offsetting requirements prescribed in FASB ASC Topic 210-20, ‘‘Balance Sheet— Offsetting’’ (‘‘ASC Topic 210-20’’). 88 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 2. Significant Accounting Policies (Continued) Securities lending fees received and paid by the Company are included in interest income and interest expense, respectively, in the consolidated statements of comprehensive income. Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase Securities purchased under agreements to resell, which are reported as collateralized financing transactions, are recorded at contract value, which approximates fair value. To ensure that the fair value of the underlying collateral remains sufficient, the collateral is valued daily with additional collateral obtained or excess collateral returned, as permitted under contractual provisions. The Company does not net, in the consolidated statements of financial condition, securities purchased under agreements to resell transactions and securities sold under agreements to repurchase transactions entered into with the same counterparty that do not meet the offsetting requirements prescribed in ASC Topic 210-20. Financial Instruments Owned and Financial Instruments Sold, But Not Yet Purchased, at Fair Value Financial instrument transactions are accounted for on a trade date basis. Financial instruments owned and financial instruments sold, but not yet purchased are stated at fair value based upon quoted market prices. The Company’s financial instruments pledged to counterparties where the counterparty has the right, by contract or custom, to sell or repledge the financial instruments are reported as financial instruments owned and pledged as collateral in the consolidated statements of financial condition. The Company also enters into currency forward contracts. These transactions, which are also accounted for on a trade date basis, are agreements to exchange a fixed amount of one currency for a specified amount of a second currency at completion of the currency forward contract term. Unrealized mark-to-market gains and losses on currency forward contracts are included in financial instruments owned, at fair value or financial instruments sold, but not yet purchased, at fair value in the consolidated statements of financial condition. Customer Receivables and Payables Customer securities transactions are recorded on a settlement date basis and customer commodities transactions are recorded on a trade date basis. Receivables from and payables to customers include amounts due on cash and margin transactions, including futures contracts transacted on behalf of customers. Securities owned by customers, including those that collateralize margin loans or other similar transactions, are not reported in the consolidated statements of financial condition. Amounts receivable from customers that are determined by management to be uncollectible are recorded as customer bad debt expense in the consolidated statements of comprehensive income. Receivables from and Payables to Brokers, Dealers and Clearing Organizations Receivables from and payables to brokers, dealers and clearing organizations include net receivables and payables from unsettled trades, including amounts related to futures and options on futures contracts executed on behalf of customers, amounts receivable for securities not delivered by the Company to the purchaser by the settlement date (‘‘fails to deliver’’) and cash deposits. Payables to brokers, dealers and clearing organizations also include amounts payable for securities not received by the Company from a seller by the settlement date (‘‘fails to receive’’). 89 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 2. Significant Accounting Policies (Continued) Investments The Company makes certain strategic investments related to its business and accounts for these investments under the cost method of accounting or under the equity method of accounting as required under FASB ASC Topic 323, ‘‘Investments—Equity Method and Joint Ventures.’’ Investments accounted for under the equity method, including where the investee is a limited partnership or limited liability company, are recorded at the fair value amount of the Company’s initial investment and are adjusted each period for the Company’s share of the investee’s income or loss. The Company’s share of the income or losses from equity method investments is included in other income in the consolidated statements of comprehensive income. The recorded amounts of the Company’s equity method investments, $32 million as of December 31, 2015 ($37 million as of December 31, 2014), which are included in other assets in the consolidated statements of financial condition, increase or decrease accordingly. Contributions paid to and distributions received from equity method investees are recorded as additions or reductions, respectively, to the respective investment balance. The Company also holds exchange memberships and investments in equity securities of certain exchanges, as required to qualify as a clearing member, and strategic investments in corporate stock that do not qualify for equity method accounting. Such investments, $34 million as of December 31, 2015 ($31 million as of December 31, 2014), are recorded at cost or, if an other-than-temporary impairment in value has occurred, at a value that reflects management’s estimate of the impairment, and are also included in other assets in the consolidated statements of financial condition. Dividends received from cost basis investments are included in other income in the consolidated statements of comprehensive income when such dividends are received. A judgmental aspect of accounting for investments is evaluating whether an other-than-temporary decline in the value of an investment has occurred. The evaluation of an other-than-temporary impairment is dependent on specific quantitative and qualitative factors and circumstances surrounding an investment, including recurring operating losses, credit defaults and subsequent rounds of financing. The Company’s equity investments do not have readily determinable market values. All investments are reviewed for changes in circumstances or occurrence of events that suggest the Company’s investment may not be recoverable. If an unrealized loss on any investment is considered to be other-than- temporary, the loss is recognized in the period the determination is made. Property, Equipment and Intangible Assets Property, equipment and intangible assets, which are included in other assets in the consolidated statements of financial condition, consist of leasehold improvements, computer equipment, software developed for the Company’s internal use, office furniture, equipment and acquired technology. Property and equipment are recorded at historical cost, less accumulated depreciation and amortization. Additions and improvements that extend the lives of assets are capitalized, while expenditures for repairs and maintenance are expensed as incurred. Depreciation and amortization are computed using the straight-line method. Equipment is depreciated over the estimated useful lives of the assets, while leasehold improvements are amortized over the lesser of the estimated economic useful life of the asset or the term of the lease. Computer equipment is depreciated over three to five years and office furniture and equipment are depreciated over five to seven years. Qualifying costs for internally developed software are capitalized and amortized over the expected useful life of the developed software, not to exceed three years. Intangible assets with a finite life are amortized on a 90 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 2. Significant Accounting Policies (Continued) straight line basis over their estimated useful lives of three years, and tested for recoverability whenever events indicate that the carrying amounts may not be recoverable. Comprehensive Income and Foreign Currency Translation The Company’s operating results are reported in the consolidated statements of comprehensive income pursuant to FASB ASC Topic 220, ‘‘Comprehensive Income.’’ Comprehensive income consists of two components: net income and other comprehensive income (‘‘OCI’’). The Company’s OCI is comprised of gains and losses resulting from translating foreign currency financial statements of non-U.S. subsidiaries, net of related income taxes, where applicable. In general, the practice and intention of the Company is to reinvest the earnings of its non-U.S. subsidiaries in those operations, therefore tax is usually not accrued. The Company’s non-U.S. domiciled subsidiaries have a functional currency that is other than the U.S. dollar. Such subsidiaries’ assets and liabilities are translated into U.S. dollars at period-end exchange rates, and revenues and expenses are translated at average exchange rates prevailing during the period. Adjustments that result from translating amounts from a subsidiary’s functional currency to the U.S. dollar (as described above) are reported net of tax, where applicable, in accumulated OCI in the consolidated statements of financial condition. During 2013, the Company derecognized accumulated OCI of a $5 million loss attributable to its Brazilian subsidiary, IB Brasil Participa¸c˜oes Ltda, which was liquidated during the year, and recognized a foreign currency translation loss, before taxes, which is included in other income in the consolidated statements of comprehensive income. Revenue Recognition Trading Gains Trading gains and losses are recorded on trade date and are reported on a net basis. Trading gains and losses are comprised of changes in the fair value of financial instruments owned, at fair value and financial instruments sold, but not yet purchased, at fair value (i.e., unrealized gains and losses) and realized gains and losses related to the Company’s market making business segment. Included in trading gains are net gains and losses on stocks, U.S. and foreign government securities, corporate and municipal bonds, options, futures, foreign exchange and other derivative instruments. Dividends are integral to the valuation of stocks and interest is integral to the valuation of fixed income instruments. Accordingly, both dividends and interest income and expense attributable to financial instruments owned, at fair value and financial instruments sold, but not yet purchased, at fair value are reported on a net basis in trading gains in the consolidated statements of comprehensive income. Commissions and Execution Fees Commissions earned for executing and clearing transactions are accrued on a trade date basis and are reported as commissions and execution fees in the consolidated statements of comprehensive income. 91 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 2. Significant Accounting Policies (Continued) Interest Income and Expense The Company earns interest income and incurs interest expense primarily in connection with its electronic brokerage customer business and its securities lending activities, which are recorded on the accrual basis and are included in interest income and interest expense, respectively, in the consolidated statements of comprehensive income. Foreign Currency Gains and Losses Currency translation refers to the gains and losses resulting from foreign currency transactions. Foreign currency translation gains and losses related to the Company’s currency diversification strategy are included in other income in the consolidated statements of comprehensive income. Foreign currency translation gains and losses related to the market making core-business activities are included in trading gains in the consolidated statements of comprehensive income. Electronic brokerage foreign currency translation gains and losses, arising from currency swap transactions, are included in interest income in the consolidated statements of comprehensive income. Income Taxes The Company accounts for income taxes in accordance with FASB ASC Topic 740, ‘‘Income Taxes’’ (‘‘ASC Topic 740’’). The Company’s income tax expense, deferred tax assets and liabilities, and reserves for unrecognized tax benefits are based on enacted tax laws (see Note 12) and reflect management’s best assessment of estimated future taxes to be paid. The Company is subject to income taxes in both the U.S. and numerous foreign jurisdictions. Determining income tax expense requires significant judgments and estimates. The Company recognizes interest related to income tax matters as interest income or interest expense and penalties related to income tax matters as income tax expense in the consolidated statements of comprehensive income. Deferred income tax assets and liabilities arise from temporary differences between the tax and financial statements recognition of the underlying assets and liabilities. In evaluating the ability to recover deferred tax assets within the jurisdictions from which they arise, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, historical results are adjusted for changes in accounting policies and incorporate assumptions including the amount of future state, federal and foreign pre-tax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax-planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates the Company is using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, three years of cumulative operating income (loss) are considered. Deferred income taxes have not been provided for U.S. tax liabilities or for additional foreign taxes on the unremitted earnings of foreign subsidiaries that have been indefinitely reinvested. 92 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 2. Significant Accounting Policies (Continued) The calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across the Company’s global operations. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. The Company is not aware of any such changes that would have a material effect on the Company’s results of operations, cash flows, or financial position. The Company recognizes that a tax benefit from an uncertain tax position only when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits. A tax position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement. The Company records tax liabilities in accordance with ASC Topic 740 and adjusts these liabilities when management’s judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in payments that are different from the current estimates of these tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information becomes available. 93 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 2. Significant Accounting Policies (Continued) Recently Issued Accounting Pronouncements Following is a summary of recently issued FASB Accounting Standards Updates (‘‘ASUs’’) that have affected or may affect the Company’s consolidated financial statements: Affects Status ASU 2015-02 Consolidation (Topic 810): Amendments to the Consolidation Analysis.

Trading Activities and Related Risks The Company’s trading activities include providing securities market making and brokerage services. Trading activities expose the Company to market and credit risks. These risks are managed in accordance with established risk management policies and procedures. To accomplish this, management has established a risk management process that includes: (cid:129) a regular review of the risk management process by executive management as part of its oversight role; (cid:129) defined risk management policies and procedures supported by a rigorous analytic framework; and 94 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 3. Trading Activities and Related Risks (Continued) (cid:129) articulated risk tolerance levels as defined by executive management that are regularly reviewed to ensure that the Company’s risk-taking is consistent with its business strategy, capital structure, and current and anticipated market conditions. Market Risk The Company is exposed to various market risks. Exposures to market risks arise from equity price risk, foreign currency exchange rate fluctuations and changes in interest rates. The Company seeks to mitigate market risk associated with trading inventories by employing hedging strategies that correlate rate, price and spread movements of trading inventories and related financing and hedging activities. The Company uses a combination of cash instruments and exchange traded derivatives to hedge its market exposures. The Company does not apply hedge accounting. The following discussion describes the types of market risk faced: Equity Price Risk Equity price risk arises from the possibility that equity security prices will fluctuate, affecting the value of equity securities and other instruments that derive their value from a particular stock, a defined basket of stocks, or a stock index. The Company is subject to equity price risk primarily in financial instruments held. The Company attempts to limit such risks by continuously reevaluating prices and by diversifying its portfolio across many different options, futures and underlying securities and avoiding concentrations of positions based on the same underlying security. Currency Risk Currency risk arises from the possibility that fluctuations in foreign exchange rates will impact the value of financial instruments. The Company manages this risk using spot (i.e., cash) currency transactions, currency futures contracts and currency forward contracts. As a global market maker trading on exchanges around the world in multiple currencies, the Company is exposed to foreign currency risk. The Company actively manages its currency exposure using hedging strategies that are based on a defined basket of 16 currencies internally referred to as the ‘‘GLOBAL.’’ These strategies minimize the fluctuation of the Company’s net worth as expressed in GLOBALs, thereby diversifying its risk in alignment with these global currencies, weighted by the Company’s view of their importance. As the Company’s financial results are reported in U.S. dollars, the change in the value of the GLOBAL as expressed in U.S. dollars affects the Company’s earnings. The impact of this currency diversification strategy in the Company’s earnings is included in other income in the consolidated statements of comprehensive income. Interest Rate Risk Interest rate risk arises from the possibility that changes in interest rates will affect the value of financial instruments. The Company is exposed to interest rate risk on cash and margin balances, positions carried in equity and fixed income securities, options, and futures and on its borrowings. These risks are managed through investment policies and by entering into interest rate futures contracts. 95 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 3. Trading Activities and Related Risks (Continued) Credit Risk The Company is exposed to risk of loss if an individual, counterparty or issuer fails to perform its obligations under contractual terms (‘‘default risk’’). Both cash instruments and derivatives expose the Company to default risk. The Company has established policies and procedures for mitigating credit risk on principal transactions, including reviewing and establishing limits for credit exposure, maintaining collateral, and continually assessing the creditworthiness of counterparties. The Company’s credit risk is limited in that substantially all of the contracts entered into are settled directly at securities and commodities clearing houses and a small portion is settled through member firms and banks with substantial financial and operational resources. The Company seeks to control the risks associated with its customer margin activities by requiring customers to maintain collateral in compliance with regulatory and internal guidelines. In the normal course of business, the Company executes, settles, and finances various customer securities transactions. Execution of these transactions includes the purchase and sale of securities which exposes the Company to default risk arising from the potential that customers or counterparties may fail to satisfy their obligations. In these situations, the Company may be required to purchase or sell financial instruments at unfavorable market prices to satisfy obligations to customers or counterparties. Liabilities to other brokers and dealers related to unsettled transactions (i.e., securities fails to receive) are recorded at the amount for which the securities were purchased, and are paid upon receipt of the securities from other brokers or dealers. In the case of aged securities fails to receive, the Company may purchase the underlying security in the market and seek reimbursement for any losses from the counterparty. For cash management purposes, the Company enters into short-term securities purchased under agreements to resell and securities sold under agreements to repurchase transactions (‘‘repos’’) in addition to securities borrowing and lending arrangements, all of which may result in credit exposure in the event the counterparty to a transaction is unable to fulfill its contractual obligations. Repos are collateralized by securities with a market value in excess of the obligation under the contract. Similarly, securities lending agreements are collateralized by deposits of cash or securities. The Company attempts to minimize credit risk associated with these activities by monitoring collateral values on a daily basis and requiring additional collateral to be deposited with or returned to the Company as permitted under contractual provisions. Concentrations of Credit Risk The Company’s exposure to credit risk associated with its trading and other activities is measured on an individual counterparty basis, as well as by groups of counterparties that share similar attributes. Concentrations of credit risk can be affected by changes in political, industry, or economic factors. To reduce the potential for risk concentration, credit limits are established and exposure is monitored in light of changing counterparty and market conditions. As of December 31, 2015, the Company did not have any material concentrations of credit risk outside the ordinary course of business. 96 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 3. Trading Activities and Related Risks (Continued) Off-Balance Sheet Risks The Company may be exposed to a risk of loss not reflected in the consolidated financial statements to settle futures and certain over-the-counter contracts at contracted prices, which may require repurchase or sale of the underlying products in the market at prevailing prices. Accordingly, these transactions result in off-balance sheet risk as the Company’s cost to liquidate such contracts may exceed the amounts reported in the Company’s consolidated statements of financial condition. 4. Equity and Earnings Per Share In connection with IBG, Inc.’s initial public offering of Class A common stock (‘‘IPO’’) in May 2007, it purchased 10.0% of the membership interests in IBG LLC from IBG Holdings LLC (‘‘Holdings’’), became the sole managing member of IBG LLC and began to consolidate IBG LLC’s financial results into its financial statements. Holdings owns all of IBG, Inc.’s Class B common stock, which has voting rights in proportion to its ownership interests in IBG LLC, approximately 84.3% as of December 31, 2015. The consolidated financial statements reflect the results of operations and financial position of IBG, Inc., including consolidation of its investment in IBG LLC and its subsidiaries. The noncontrolling interests in IBG LLC attributable to Holdings are reported as a component of total equity in the consolidated statements of financial condition, as described below. Recapitalization and Post-IPO Capital Structure Immediately prior to and immediately following the consummation of the IPO, IBG, Inc., Holdings, IBG LLC and the members of IBG LLC consummated a series of transactions collectively referred to herein as the ‘‘Recapitalization.’’ In connection with the Recapitalization, IBG, Inc., Holdings and the historical members of IBG LLC entered into an exchange agreement, dated as of May 3, 2007 (the ‘‘Exchange Agreement’’), pursuant to which the historical members of IBG LLC received membership interests in Holdings in exchange for their membership interests in IBG LLC. Additionally, IBG, Inc. became the sole managing member of IBG LLC. In connection with the consummation of the IPO, Holdings used the net proceeds to redeem 10.0% of members’ interests in Holdings in proportion to their interests. Immediately following the Recapitalization and IPO, Holdings owned approximately 90% of IBG LLC and 100% of IBG, Inc.’s Class B common stock, which has voting power in IBG, Inc. in proportion to Holdings’ ownership of IBG LLC. Since consummation of the IPO and Recapitalization, IBG, Inc.’s equity capital structure has been comprised of Class A and Class B common stock. All shares of common stock have a par value of $0.01 per share and have identical rights to earnings and dividends and in liquidation. As described previously in this Note 4, Class B common stock has voting power in IBG, Inc. proportionate to the extent of Holdings’ and IBG, Inc.’s respective ownership of IBG LLC. As of December 31, 2015 and December 31, 2014, 1,000,000,000 shares of Class A common stock were authorized, of which 64,121,150 and 58,612,245 shares have been issued; and 63,985,335 and 58,473,186 shares were outstanding, respectively. Class B common stock is comprised of 100 authorized shares, of which 100 shares were issued and outstanding as of December 31, 2015 and December 31, 2014, respectively. In addition, 10,000 shares of preferred stock have been authorized, of which no shares are issued or outstanding as of December 31, 2015 and December 31, 2014, respectively. 97 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 4. Equity and Earnings Per Share (Continued) As a result of a federal income tax election made by IBG LLC applicable to the acquisition of IBG LLC member interests by IBG, Inc., the income tax basis of the assets of IBG LLC acquired by IBG, Inc. have been adjusted based on the amount paid for such interests. Deferred tax assets were recorded as of the IPO date and in connection with subsequent redemptions of Holdings member interests in exchange for common stock. These deferred tax assets are included in other assets in the Company’s consolidated statements of financial condition and are being amortized as additional deferred income tax expense over 15 years from the IPO date and from the additional redemption dates, respectively, as allowable under current tax law. As of December 31, 2015 and December 31, 2014, the unamortized balance of these deferred tax assets was $288 million and $279 million, respectively. IBG, Inc. also entered into an agreement (the ‘‘Tax Receivable Agreement’’) with Holdings to pay Holdings (for the benefit of the former members of IBG LLC) 85% of the tax savings that IBG, Inc. actually realizes as the result of tax basis increases. These payables to Holdings are reported as payable to affiliate in the Company’s consolidated statements of financial condition. The remaining 15% is accounted for as a permanent increase to additional paid-in capital in the Company’s consolidated statements of financial condition. The cumulative amounts of deferred tax assets, payables to Holdings and additional paid-in capital arising from stock offerings from the date of the IPO through December 31, 2015 were $460 million, $391 million and $69 million, respectively. Amounts payable under the Tax Receivable Agreement are payable to Holdings annually following the filing of IBG, Inc.’s federal income tax return. The Company has paid Holdings a cumulative total of $99 million through December 31, 2015 pursuant to the terms of the Tax Receivable Agreement. The Exchange Agreement, as amended June 6, 2012, provides for future redemptions of member interests and for the purchase of member interests in IBG LLC by IBG, Inc. from Holdings, which could result in IBG, Inc. acquiring the remaining member interests in IBG LLC that it does not own. On an annual basis, members of Holdings are able to request redemption of their interests. At the time of IBG, Inc.’s IPO in 2007, three hundred sixty (360) million shares of authorized common stock were reserved for future sales and redemptions. From 2008 through 2010, Holdings redeemed 5,013,259 IBG LLC interests with a total value of $114 million, which redemptions were funded using cash on hand at IBG LLC. Upon cash redemption these IBG LLC interests were retired. From 2011 through 2014, IBG, Inc. issued 8,025,517 shares of common stock directly to Holdings in exchange for an equivalent number of member interests in IBG LLC. In 2015, the Company issued 3,021,778 shares of Class A common stock (with a fair value of $132 million) to Holdings in exchange for an equivalent number of member interests in IBG LLC. As a consequence of these redemption transactions, and distribution of shares to employees (see Note 11), IBG, Inc.’s interest in IBG LLC has increased to approximately 15.7%, with Holdings owning the remaining 84.3% as of December 31, 2015. The redemptions also resulted in an increase in the Holdings interest held by Mr. Thomas Peterffy and his affiliates from approximately 84.6% at the IPO to approximately 88.7% as of December 31, 2015. 98 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 4.

Collateralized Transactions The Company enters into securities borrowing and lending transactions and agreements to repurchase and resell securities to finance trading inventory, to obtain securities for settlement and to earn residual interest rate spreads. In addition, the Company’s customers pledge their securities owned to collateralize margin loans. Under these transactions, the Company either receives or provides collateral, including equity, corporate debt and U.S. government securities. Under many agreements, the Company is permitted to sell or repledge securities received as collateral and use these securities to secure securities purchased under agreements to resell, enter into securities lending transactions or deliver these securities to counterparties to cover short positions. The Company also engages in securities financing transactions with and for customers through margin lending. Customer receivables generated from margin lending activity are collateralized by customer- owned securities held by the Company. Customers’ required margin levels and established credit limits are monitored continuously by risk management staff using automated systems. Pursuant to the Company’s policy and as enforced by such systems, customers are required to deposit additional collateral or reduce positions, when necessary to avoid automatic liquidation of their positions. Margin loans are extended to customers on a demand basis and are not committed facilities. Factors considered in the acceptance or rejection of margin loans are the amount of the loan, the degree of leverage being employed in the customer account and an overall evaluation of the customer’s portfolio to ensure proper diversification or, in the case of concentrated positions, appropriate liquidity of the underlying collateral. Additionally, transactions relating to concentrated or restricted positions are limited or prohibited by raising the level of required margin collateral (to 100% in the extreme case). Underlying collateral for margin loans is evaluated with respect to the liquidity of the collateral positions, valuation of securities, volatility analysis and an evaluation of industry concentrations. Adherence to the Company’s collateral policies significantly limits the Company’s credit exposure to margin loans in the event of a customer’s default. Under margin lending agreements, the Company may request additional margin collateral from customers and may sell securities that have not been paid for or purchase securities sold but not delivered from customers, if necessary. As of December 31, 2015 and December 31, 2014, approximately $17.0 billion and $17.1 billion, respectively, of customer margin loans were outstanding. 108 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 7.

In the normal course of business, the Company pledges qualified securities with clearing organizations to satisfy daily margin and clearing fund requirements. As of December 31, 2015 and December 31, 2014, the majority of the Company’s U.S. and foreign government securities owned were pledged to clearing organizations.

Short-Term Borrowings Short-term borrowings consist primarily of collateralized borrowing facilities with clearing banks in multiple currencies that bear interest at variable overnight rates based on interbank funds rates prevailing in the respective currencies. In addition, the Company has available secured and unsecured overnight bank loan facilities. All short-term borrowings outstanding as of December 31, 2015 and 2014 were either repaid on the next business day or rolled forward and, accordingly, their carrying values approximated fair values. 109 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 8.

Senior Secured Revolving Credit Facility On May 17, 2012, IBG LLC entered into a $100 million three-year senior secured revolving credit facility with Bank of America, N.A. as administrative agent and Citibank, N.A., as syndication agent. This credit facility replaced a similar two-year facility that expired on May 18, 2012. On August 8, 2014 IBG LLC elected to terminate this credit facility. 10.

Market data fees are charged to customers based upon market data services provided and are largely offset by the related cost to obtain the underlying market data from third party vendors. Risk exposure fees are earned from a small minority of customers’ accounts with positions on which market risk exceeds certain thresholds. Gains and losses on financial instruments, at fair value and other investments include realized and unrealized gains and losses on financial instruments that are not held for the Company’s market making operations or from securities that are subject to restrictions, and the Company’s interests in the earnings of equity method investees and dividends received on cost-basis investments. 110 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 11. Employee Incentive Plans Defined Contribution Plan The Company offers substantially all employees of U.S.-based Operating Companies who have met minimum service requirements the opportunity to participate in defined contribution retirement plans qualifying under the provisions of Section 401(k) of the Internal Revenue Code. The general purpose of this plan is to provide employees with an incentive to make regular savings in order to provide additional financial security during retirement. This plan provides for the Company to match 50% of the employees’ pre-tax contribution, up to a maximum of 10% of eligible earnings. The employee is vested in the matching contribution incrementally over six years. Included in employee compensation and benefits expenses in the consolidated statements of comprehensive income were $3 million of plan contributions for the three years ended December 31, 2015, 2014 and 2013, respectively. Return on Investment Dollar Units (‘‘ROI Dollar Units’’) From 1998 through January 1, 2006, IBG LLC granted all non-member employees ROI Dollar Units, which are redeemable under the amended provisions of the plan, and in accordance with regulations issued by the Internal Revenue Service (Section 409A of the Internal Revenue Code). Upon redemption, the grantee is entitled to accumulated earnings on the face value of the certificate, but not the actual face value. For grants made in 1998 and 1999, grantees may redeem the ROI Dollar Units after vesting on the fifth anniversary of the date of their grant and prior to the tenth anniversary of the date of their grant. For grants made between January 1, 2000 and January 1, 2005, grantees must elect to redeem the ROI Dollar Units upon the fifth, seventh or tenth anniversary date. These ROI Dollar Units have vested at the fifth anniversary of the date of their grant and will continue to accumulate earnings until the elected redemption date. For grants made on or after January 1, 2006, all ROI Dollar Units vested on the fifth anniversary date of their grant and were or will be automatically redeemed. Subsequent to the IPO, no additional ROI Dollar Units have been or will be granted, and non-cash compensation to employees will consist primarily of grants of shares of restricted common stock as described below under ‘‘2007 Stock Incentive Plan.’’ During the second quarter of 2015, this plan was terminated as the Company fully paid its remaining obligation to employees. Therefore as of December 31, 2015, the Company had no payables to employees for ROI Dollar Units. As of December 31, 2014, payable to employees for ROI Dollar Units was $3 million which is included in accounts payable, accrued expenses and other liabilities in the consolidated statements of financial condition. 2007 ROI Unit Stock Plan In connection with the IPO, the Company adopted the IBG, Inc. 2007 ROI Unit Stock Plan (‘‘ROI Unit Stock Plan’’). Under this plan, certain employees of IBG LLC who held ROI Dollar Units, at the employee’s option, elected to invest their ROI Dollar Unit accumulated earnings as of December 31, 2006 in shares of restricted common stock. An aggregate of 1,271,009 shares of restricted common stock (consisting of 1,250,000 shares issued under the ROI Unit Stock Plan and 21,009 shares under the 2007 Stock Incentive Plan, as described below), with a fair value at the date of grant of $38 million were issued to IBG LLC and held as treasury stock, to be distributed to employees in accordance with the following schedule and subject to the conditions below: (cid:129) 10% on the date of the IPO (or on the first anniversary of the IPO, in the case of U.S. ROI Unit holders who made the above-referenced elections after December 31, 2006); and 111 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 11. Employee Incentive Plans (Continued) (cid:129) an additional 15% on each of the first six anniversaries of the date of the IPO, assuming continued employment with the Company and compliance with other applicable covenants. Of the fair value at the date of grant, $18 million represented the accumulated ROI Dollar Unit value elected to be invested by employees in restricted common stock and such amount was accrued for as of December 31, 2006. The remainder was being ratably accrued as compensation expense by the Company from the date of the IPO over the requisite service period represented by the aforementioned distribution schedule. As of December 31, 2015, the Company has 6,370 shares of common stock remaining to be distributed to former employees under the ROI Unit Stock Plan. 2007 Stock Incentive Plan Under the Company’s 2007 Stock Incentive Plan (the ‘‘Stock Incentive Plan’’), up to 30 million shares of the Company’s common stock may be granted and issued to directors, officers, employees, contractors and consultants of the Company. The purpose of the Stock Incentive Plan is to promote the Company’s long-term financial success by attracting, retaining and rewarding eligible participants. As a result of the Company’s organizational structure, a description of which can be found in ‘‘Business—Our Organizational Structure’’ in Part I Item 1 of this annual Report Form 10-K, there is no dilutive effect upon ownership of common stockholders of issuing shares under the Stock Incentive Plan. The issuances do not dilute the book value of the ownership of common stockholders since the restricted stock units are granted at market value, and upon their vesting and the related issuance of shares of common stock, the ownership of IBG, Inc. in IBG LLC, increases proportionately to the shares issued. As a result of such proportionate increase in share ownership, the dilution upon issuance of common stock is borne by IBG LLC’s majority member (i.e., noncontrolling interest), Holdings, and not by IBG, Inc. or its common stockholders. Additionally, dilution of earnings that may take place after issuance of common stock is reflected in EPS reported in the Company’s financial statements. The EPS dilution can be neither estimated nor projected, but historically it has not been material. The Stock Incentive Plan is administered by the Compensation Committee of the Company’s Board of Directors. The Compensation Committee has discretionary authority to determine the eligibility to participate in the Stock Incentive Plan and establishes the terms and conditions of the stock awards, including the number of awards granted to each participant and all other terms and conditions applicable to such awards in individual grant agreements. Awards are expected to be made primarily through grants of restricted common stock. Stock Incentive Plan awards are subject to issuance over time and may be forfeited upon the participant’s termination of employment or violation of certain applicable covenants prior to issuance, unless determined otherwise by the Compensation Committee. The Stock Incentive Plan provides that, upon a change in control, the Compensation Committee may, at its discretion, fully vest any granted but not yet earned awards under the Stock Incentive Plan, or provide that any such granted but not yet earned awards will be honored or assumed, or new rights substituted by the new employer on a substantially similar basis and on terms and conditions substantially comparable to those of the Stock Incentive Plan. 112 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 11. Employee Incentive Plans (Continued) The Company expects to continue to grant awards on or about December 31 of each year to eligible participants as part of an overall plan of equity compensation. Shares of common stock vest, and become distributable to participants in accordance with the following schedule: (cid:129) 10% on the first vesting date, which is on or about May 9 of each year; and (cid:129) an additional 15% on each of the following six anniversaries of the first vesting, assuming continued employment with the Company and compliance with non-competition and other applicable covenants. Awards granted to external directors vest, and are distributed, over a five-year period (20% per year) commencing one year after the date of grant. A total of 22,996 shares have been granted to the external directors cumulatively since the plan inception. Stock Incentive Plan share grants (excluding 21,009 shares issued pursuant to the ROI Unit Stock Plan described above) and the related fair values since the plan inception are presented in the table below: Prior periods (since inception) . . . . . . . . . . . . . . . . . . . . .

In accordance with the vesting schedule, outstanding awards vest and are distributed to participants yearly on or about May 9 of each year. At the end of each year, there are no vested awards that remain undistributed. Compensation expense related to the Stock Incentive Plan recognized in the consolidated statements of comprehensive income was $50 million, $41 million and $41 million for the three years ended December 31, 2015, 2014 and 2013, respectively. Estimated future compensation costs for unvested awards, net of forfeiture credits, as of December 31, 2015 are $37 million. 113 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 11.

(2) Intrinsic value of SIP shares distributed represents the compensation value reported to the participants. Awards granted under the stock plans are subject to forfeiture in the event a participant ceases employment with the Company. The stock plans provide that participants who discontinue employment with the Company without cause and continue to meet the terms of the plans’ post-employment provisions will forfeit 50% of unvested previously granted awards unless the participant is over the age of 59, in which case the participant would be eligible to receive 100% of unvested awards previously granted. Distributions of remaining awards granted on or before January 1, 2009 to former participants will occur within 90 days of the anniversary of the termination of employment date over a five (5) year vesting schedule, 12.5% in each of the first four years and 50% in the fifth year. Distributions of remaining awards granted on or after January 1, 2010 to former participants will occur over the remaining vesting schedule applicable to each grant. Through December 31, 2015, a total of 306,668 shares have been distributed under these post-employment provisions. These distributions are included in the table above. 114 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 12. Income Taxes Income tax expense for the three years ended December 31, 2015, 2014 and 2013 differs from the U.S. federal statutory rate primarily due to the taxation treatment of income attributable to noncontrolling interests in IBG LLC. These noncontrolling interests are subject to U.S. taxation as partnerships. Accordingly, the income attributable to these noncontrolling interests is reported in the consolidated statements of comprehensive income, but the related U.S. income tax expense attributable to these noncontrolling interests is not reported by the Company as it is the obligation of the individual partners. Income tax expense is also affected by the differing effective tax rates in foreign, state and local jurisdictions where certain of the Company’s subsidiaries are subject to corporate taxation. Deferred income taxes arise primarily due to the amortization of the deferred tax assets recognized in connection with the common stock offerings (see Note 4), differences in the valuation of financial assets and liabilities, and for other temporary differences arising from the deductibility of compensation and depreciation expenses in different time periods for book and income tax return purposes. For the three years ended December 31, 2015, 2014 and 2013, the provision for income taxes consisted of: Year-ended December 31, 2015 2014 2013 (in millions) Current Federal . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The Company is subject to taxation in the U.S. and various states and foreign jurisdictions. As of December 31, 2015, the Company is no longer subject to U.S. Federal and State income tax examinations for tax years prior to 2010, and to non-U.S. income tax examinations for tax years prior to 2006. As of December 31, 2015, accumulated earnings held by non-U.S. subsidiaries totaled $1.0 billion (as of December 31, 2014 $1.0 billion). Of this amount, approximately $0.4 billion (as of December 31, 2014 $0.4 billion) is attributable to earnings of the Company’s foreign subsidiaries that are considered ‘‘pass-through’’ entities for U.S. income tax purposes. Since the Company accounts for U.S. income taxes on these earnings on a current basis, no additional U.S. tax consequences would result from the repatriation of these earnings other than that which would be due arising from currency fluctuations between the time the earnings are reported for U.S. tax purposes and when they are remitted. With respect to certain of these subsidiaries’ accumulated earnings (approximately $0.3 billion and $0.3 billion as of December 31, 2015 and December 31, 2014, respectively), repatriation would result in additional foreign taxes in the form of dividend withholding tax imposed on the recipient of the distribution or dividend distribution tax imposed on the payor of the distribution. The Company has not provided for its proportionate share of these additional foreign taxes as it does not intend to repatriate these earnings in the foreseeable future. For the same reason, the Company has not provided deferred U.S. tax on cumulative translation adjustments associated with these earnings. The remainder of the accumulated earnings are attributable to non-U.S. subsidiaries that are not considered ‘‘pass-through’’ entities for U.S. tax purposes. The Company’s U.S. tax basis in the stock of most of these entities exceeds its book basis. Establishing a deferred tax asset pursuant to ASC Topic 740 is not permitted as this difference will not reverse in the foreseeable future. In the instances 116 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 12. Income Taxes (Continued) in which the Company’s book basis were to exceed its U.S. tax basis, no deferred tax liability would be established as the Company would consider the earnings of those entities to be indefinitely reinvested. 13. Property, Equipment and Intangible Assets Property, equipment and intangible assets, which are included in other assets in the consolidated statements of financial condition, consist of leasehold improvements, computer equipment, software developed for the Company’s internal use, office furniture, equipment and acquired technology.

Amortization expense related to intangible assets is expect to be approximately $2 million for years ended December 31, 2016, 2017 and 2018, respectively. 14. Commitments, Contingencies and Guarantees Claims Against Customers On January 15, 2015, due to the sudden move in the value of the Swiss franc that followed an unprecedented action by the Swiss National Bank, which removed a previously instituted and repeatedly reconfirmed cap of the currency relative to the Euro, several of the Company’s customers who held currency futures and spot positions suffered losses in excess of their deposits with the Company. The Company took immediate action to hedge its exposure to the foreign currency receivables from these customers. The Company estimates the losses related to this event, net of hedging activity and debt collection efforts, to be approximately $119 million. The Company is actively pursuing collection of the debts. The ultimate effect of this incident on the Company’s results will depend upon the outcome of the Company’s debt collection efforts. 117 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 14. Commitments, Contingencies and Guarantees (Continued) Litigation The Company is subject to certain pending and threatened legal actions which arise out of the normal course of business. Litigation is inherently unpredictable, particularly in proceedings where claimants seek substantial or indeterminate damages, or which are in their early stages. The Company has not been able to quantify the actual loss or range of loss related to such legal proceedings, the manner in which they will be resolved, the timing of final resolution or the ultimate settlement. Management believes that the resolution of these actions will not have a material effect, if any, on the Company’s business or financial condition, but may have a material impact on the results of operations for a given period. The Company accounts for potential losses related to litigation in accordance with FASB ASC Topic 450, ‘‘Contingencies.’’ As of December 31, 2015 and 2014, reserves provided for potential losses related to litigation matters were not material.

(‘‘Trading Technologies’’) commenced an action in the U.S. District Court for the Northern District of Illinois, Eastern Division, against IBG LLC and IB LLC (‘‘Defendants’’) alleging infringement of twelve U.S. patents and seeking, among other things, unspecified damages and injunctive relief. The Defendants filed an answer denying the claims and asserted counterclaims seeking a declaration that the patents have not been infringed and are invalid. The Defendants and/or certain codefendants filed petitions with the U.S. Patent and Trademark Office (‘‘USPTO’’) for Covered Business Method (‘‘CBM’’) Review on eight of the asserted patents, and will likely file petitions with respect to the others. Thus far the USPTO issued decisions instituting CBM Review on two of the asserted patents and has made a finding that it is more likely than not that the patents are invalid. While it is too early to predict the outcome of the matter, the Company believes it has meritorious defenses to the allegations made in the complaint and intend to defend itself vigorously against them. Class Action Matter On December 18, 2015, a former individual customer filed a purported class action complaint against IB LLC, IBG, Inc., and Thomas Frank, PhD, the Company’s Executive Vice President and Chief Information Officer, in the U.S. District Court for the District of Connecticut. The complaint alleges that the former customer and members of the purported class of IB LLC’s customers were harmed by alleged ‘‘flaws’’ in the computerized system used by the Company to close out (i.e., liquidate) positions in customer brokerage accounts that have margin deficiencies. The complaint seeks, among other things, undefined compensatory damages and declaratory and injunctive relief. The Company believes that the complaint is without merit and the Company has filed a motion to dismiss it. Among other things, the Company’s customer agreement, federal law and associated industry rules grant broker-dealers broad discretion to close out margin-deficient customer accounts for the broker’s protection. Further, the Company does not believe that a purported class action is appropriate given the great differences in portfolios, markets and many other circumstances surrounding the liquidation of any particular customer’s margin-deficient account. IB LLC and the related defendants intend to defend themselves vigorously against the case and, consistent with past practice in connection with this type of unwarranted action, any potential claims for counsel fees and expenses incurred in defending the case shall be fully pursued against the plaintiff. 118 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 14. Commitments, Contingencies and Guarantees (Continued) Leases Operating Companies have non-cancelable operating leases covering office space. All but one of the office space leases are subject to escalation clauses based on specified costs incurred by the respective landlords and contain renewal elections. Rent expense calculated on a straight-line basis for the Company was $14 million, $13 million and $13 million for the three years ended December 31, 2015, 2014 and 2013, respectively, and is included in occupancy, depreciation and amortization expenses in the consolidated statements of comprehensive income. As of December 31, 2015, the Company’s minimum annual lease commitments totaled $59 million, as follows: Year 2016 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2017 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2018 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2019 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

(in millions) $13 12 13 4 17 $59 Guarantees Certain of the Operating Companies provide guarantees to securities clearing houses and exchanges which meet the accounting definition of a guarantee under FASB ASC Topic 460, ‘‘Guarantees.’’ Under standard membership agreements, clearing house and exchange members are required to guarantee collectively the performance of other members. Under the agreements, if a member becomes unable to satisfy its obligations, other members would be required to meet shortfalls. In the opinion of management, the Operating Companies’ liability under these arrangements is not quantifiable and could exceed the cash and securities they have posted as collateral. However, the potential for these Operating Companies to be required to make payments under these arrangements is remote. Accordingly, no contingent liability is carried in the consolidated statements of financial condition for these arrangements. In connection with its retail brokerage business, IB LLC or other electronic brokerage Operating Companies perform securities and commodities execution, clearance and settlement on behalf of their customers for whom they commit to settle trades submitted by such customers with the respective clearing houses. If a customer fails to fulfill its settlement obligations, the respective Operating Company must fulfill those settlement obligations. No contingent liability is carried on the consolidated statements of financial condition for such customer obligations. Other Commitments Certain clearing houses, clearing banks and firms used by certain Operating Companies are given a security interest in certain assets of those Operating Companies held by those clearing organizations. These assets may be applied to satisfy the obligations of those Operating Companies to the respective clearing organizations. 119 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Continued) 15. Segment and Geographic Information The Company has two operating business segments: electronic brokerage and market making. These segments are supported by the corporate segment which provides centralized services and executes the Company’s currency diversification strategy. The Company conducts its electronic brokerage business through its Interactive Brokers subsidiaries, which provide electronic execution and clearing services to customers worldwide. The Company conducts its market making business principally through its Timber Hill subsidiaries on the world’s leading exchanges and market centers, primarily in exchange-traded equities, equity options and equity- index options and futures. Significant transactions and balances between the Operating Companies occur, primarily as a result of certain Operating Companies holding exchange or clearing organization memberships, which are utilized to provide execution and clearing services to affiliates. Charges for transactions between segments are designed to approximate full costs. Intra-segment and intra-region income and expenses and related balances have been eliminated in this segment and geographic information to reflect the external business conducted in each segment or geographical region. Corporate items include non-allocated corporate income and expenses that are not attributed to segments for performance measurement, net gains and losses on positions held as part of our overall currency diversification strategy, corporate assets and eliminations. Management believes that the following information by business segment provides a reasonable representation of each segment’s contribution to total net revenues and income before income taxes for the three years ended December 31, 2015, 2014 and 2013, and to total assets as of December 31, 2015, 2014 and 2013.

A significant portion of the Company’s net revenues are generated by subsidiaries operating outside the U.S. International operations are comprised of electronic brokerage and market making activities in 25 countries in Europe, Asia and the Americas (outside the U.S.). In the first quarter of this year, the Company changed the presentation of its geographic segments, moving the companies and eliminations that were in the corporate segment to their respective geographic region. To provide meaningful comparison, prior period amounts have been reclassified for this change in presentation. The following table presents total net revenues and income before income taxes by geographic area for the three years ended December 31, 2015, 2014 and 2013.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. CONTROLS AND PROCEDURES Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures The Company maintains disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in the reports it files or submits under the Securities Exchange Act of 1934 (the ‘‘Exchange Act’’) is recorded, processed, summarized and reported accurately and within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer (‘‘CEO’’) and Chief Financial Officer (‘‘CFO’’), as appropriate, to allow timely decisions regarding required disclosure. Under the supervision and with the participation of our management, including our CEO and our CFO, we conducted an evaluation of our disclosure controls and procedures; as such term is defined under Exchange Act Rule 13a-15(e). Based on this evaluation, our CEO and our CFO concluded that our disclosure controls and procedures were effective as of the end of the period covered by this annual report. Management’s Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting. IBG, Inc.’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of IBG, Inc.; provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of IBG, Inc.’s management and directors; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements. In 2012, the Company’s management created the Accounting Policy Committee (the ‘‘APC’’) to provide a robust framework for the design and implementation of all relevant controls. The APC is comprised of eleven (11) experienced subject matter experts from within the Company’s accounting, tax and regulatory disciplines, and includes the CFO and the Chief Accounting Officer. The APC is responsible for assessing the effects of complex transactions and related accounting guidance on the Company’s financial statements and to report the results of its assessments to management and to the Audit Committee. The APC’s mandate includes review and approval of the adoption and implementation of accounting guidance (new or newly applicable) by the Company. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 125 Management, including our CEO and our CFO, assessed the effectiveness of IBG, Inc.’s internal control over financial reporting as of December 31, 2015. In making this assessment, management used the criteria set forth in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (‘‘COSO’’). Based on management’s assessment and those criteria, management concluded that IBG, Inc. maintained effective internal control over financial reporting as of December 31, 2015. The effectiveness of the Company’s internal control over financial reporting as of December 31, 2015, has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report, which appears herein. Changes to Internal Control Over Financial Reporting There have been no changes in our internal control over financial reporting for the year ended December 31, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 126 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Stockholders of Interactive Brokers Group, Inc. Greenwich, CT We have audited the internal control over financial reporting of Interactive Brokers Group, Inc. and subsidiaries (the ‘‘Company’’) as of December 31, 2015, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on the criteria established in Internal Control— Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 127 We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statements of financial condition as of December 31, 2015 and 2014, and the related consolidated statements of comprehensive income, cash flows and changes in equity for each of the three years in the period ended December 31, 2015, of the Company and our report dated February 26, 2016 expressed an unqualified opinion on those financial statements. /s/ Deloitte & Touche LLP New York, New York February 26, 2016 128 ITEM 9B.
