Today our customers can trade through web-based, downloadable and mobile tradingplatforms and have access to innovative trading tools to assist them with research and analysis, automated trading and account management.We operate our business in three segments.

Each of our operating segments is discussed in more detail below. For financial information regarding our segments, please refer to Note 21 to ouraudited consolidated financial statements included in this Annual Report.As a global provider of online trading services, our results of operations are impacted by a number of external factors, including market volatility,competition, the regulatory environment in the various jurisdictions and markets in which we operate and the financial condition of the retail andinstitutional customers to whom we provide our services.

We conduct our retail business primarily through ourFOREX.com and City Index brands. As of December 31, 2017, we had 185,729 funded retail accounts.Through our retail segment, we provide customers around the world access to a diverse range of global financial markets. We offer our customers access toover 12,500 financial products, including spot foreign exchange (forex), precious metals trading, as well as contracts for difference (CFDs), which areinvestment products with returns linked to the performance of underlying assets. We offer CFDs on currencies, commodities, indices, individual equities,bonds, options and interest rate products. In the United Kingdom, we offer spread bets, which are investment products similar to CFDs, but that offer morefavorable tax treatment for residents of that country. We offer these products under the diverse regulatory environments in which we operate. Because ofU.S. regulations, neither we, nor our subsidiaries, offer CFDs or spread bets in the United States or to U.S. residents.We seek to attract and support our customers through direct and indirect channels. Our primary direct channels for our retail segment are our Internetwebsites, FOREX.com and Cityindex.com, which are available in multiple languages, including English, Chinese, Japanese and Arabic. Our indirect channelincludes our relationships with introducing brokers, who solicit customers on our behalf, and white label partners, who offer our trading services to theircustomers under their own brand. Total retail trading volume sourced through direct and indirect channels was 67% and 33%, respectively, for the year endedDecember 31, 2017.We generate revenue in our retail segment principally from transaction fees we charge our customers, including the bid/offer spread, financing charges forpositions held overnight, commissions on equity CFD trades and advisory services, and other account related fees.In 2017, we generated approximately 72.7% of our retail segment trading volume from customers outside the United States. For a discussion of the risksassociated with our retail segment operations outside the United States, please refer to “Item 1A. Risk Factors.”The following sections provide additional information regarding our retail business:6 Table of ContentsInnovative trading toolsWe have made significant investment in the development and support of our award-winning proprietary trading technology in order to provide our customerswith an enhanced customer experience and multiple ways to trade and manage their accounts, tailored to their level of experience and preferred mode ofaccess. In addition, we selectively offer third party trading tools that we believe complement our proprietary offerings. We believe that our proprietary tradingtechnology has and will continue to provide us with a significant competitive advantage because we have the ability to adapt quickly to our customers’changing needs, rapidly incorporate new products and features and offer our customers multiple ways to engage with us.Competitive pricing and fast, accurate trade executionWe have longstanding relationships with a large number of institutional liquidity providers, as well as access to multiple liquidity venues. This allows us tooffer our customers superior liquidity and more competitive pricing with tighter bid/offer spreads than many of our competitors. In addition, we havedeveloped a proprietary pricing engine that electronically aggregates quotes from our liquidity sources. This ensures that our prices accurately reflect currentmarket price levels and allows us to provide our customers high-speed trade execution. In 2017, we handled over 14 million trade requests and executed99.9% of trades in less than one second, with an average execution speed of 0.03 seconds. We have established a set of standards we use to measure executionquality for FOREX.com, and we publish execution statistics on a monthly basis. The FOREX.com execution scorecard, which is available on our website,demonstrates our ability to provide fast, accurate trade executions, as well as our commitment to transparency in our business. We believe we are the onlyfirm in our industry to voluntarily publish a monthly execution scorecard with the level of detail that we provide.Efficient customer onboarding and account managementWe have developed proprietary technology to handle numerous aspects of account onboarding and customer service including account opening andcustomer verification process, fast online account funding and withdrawals with a wide variety of automated payment methods, and on-demand delivery ofcustomer information, such as account statements and other account-related reporting. We also offer account opening and funding functions on our mobiletrading applications in order to provide a superior experience to the large number of customers who trade primarily through their mobile devices. Given thehighly regulated and global nature of our business, these processes are customized to each regulatory jurisdiction in which we operate, and are furthertailored to customer needs and preferences in specific countries in order to make it easier for clients in these countries to open accounts with us and then tofund and trade in those accounts.Sophisticated risk managementBecause we are exposed to market, credit and other risks in connection with our retail business, developing and maintaining robust risk managementcapabilities is a high priority.We allow our customers to trade notional amounts greater than the funds they have on deposit with us through the use of leverage, making management ofcredit risk a key focus for us. We manage customer credit risk through a combination of providing trading tools that allow our customers' to avoid taking onexcessive risk and automated processes that close customer positions in accordance with our policies, in the event the funds in customers' accounts are notsufficient to hold their positions. One such tool available on our trading platforms is a real-time margin monitoring tool that enables customers to know whenthey are approaching their margin limits. If a customer’s equity falls below the amount required to support one or more positions, we will automaticallyliquidate positions to bring the customer’s account into margin compliance.In addition, we actively monitor and assess various market factors, including volatility and liquidity, and take steps to address identified risks, such asproactively adjusting required customer margin (both initial and maintenance). For example, on January 15, 2015, the Swiss National Bank, or SNB,unexpectedly announced that it would move interest rates to -0.75% and abandon the 1.20 floor for EUR/CHF that it had previously maintained. Theannouncement led to extraordinary volatility in the Swiss franc, which negatively impacted many market participants. However, as part of our ordinarycourse risk management process, we had identified significant risk relating to EUR/CHF products and had increased client margin requirements to 5% well inadvance of the SNB's move, which mitigated the risk of negative client equity in the event the price floor was abandoned.With respect to market risk, when a retail customer executes a trade with us, the trade may be naturally hedged against an offsetting trade from anothercustomer, hedged through an offsetting trade with one of our liquidity providers or may become part of our net exposure portfolio. For naturally hedgedtrades, we receive the entire bid/offer spread we offer our customers on the two offsetting transactions. For trades hedged with our liquidity providers, we earnthe difference between the retail bid/offer spread we offer our customers and the wholesale bid/offer spread we receive from our liquidity providers. Customer7 Table of Contentstrades in our net exposure portfolio are managed pursuant to our risk-management policies and procedures, including risk limits established by the RiskCommittee of our Board of Directors, and we receive the net gains or losses generated through the management of our net exposure.Our risk management policies and procedures have been developed to enable us to effectively manage our exposure to market risk, particularly in connectionwith the management of our net exposure. Our net exposure is evaluated continuously and is continuously rebalanced throughout the trading day, therebyminimizing the risk we will be adversely affected by changes in the market prices of the products we hold. This real-time rebalancing of our portfolio enablesus to curtail risk and to be profitable in both up and down market scenarios.Our risk management policies and procedures are established and reviewed regularly by the Risk Committee of our Board of Directors. Our risk-managementteam monitors risk exposure continuously and updates senior management both informally over the course of the trading day and formally through real-time,intraday and end-of-day reporting. We do not actively initiate proprietary market positions in anticipation of future movements in the relative prices of theproducts we offer.CustomersOur retail customers consist primarily of self-directed traders, who execute trades on their own behalf. A small number of our customers have engaged anintermediary to make trading decisions on their behalf.Our typical self-directed customer is generally comfortable making trading decisions and is specifically interested in trading leveraged products, whichgenerally have a higher risk/reward profile. For the year ended December 31, 2017, self-directed customers represented approximately 99.3% of our retailtrading volume.The intermediaries engaged by our managed account customers, which we refer to as authorized traders, include professional money managers, which tradeaggregated customer funds, and individuals that trade for a small number of customer accounts. For the year ended December 31, 2017, managed accountcustomers collectively represented approximately 0.7% of our retail trading volume.Sales and MarketingIn connection with our retail business, we look to acquire new customers as cost-efficiently as possible, primarily through online marketing efforts such asadvertising on third-party websites, search engine marketing and email marketing. Our experienced in-house marketing team creates highly targeted onlinecampaigns tailored to experienced traders, as well as marketing programs and materials designed to support and educate newer traders. We use sophisticatedtracking and measurement techniques to monitor the results of individual campaigns and continually work to optimize our overall marketing results.One of our principal lead-generation tools is to offer prospective customers access to free registered practice trading accounts for a 30-day trial period. From aprospective customer’s point of view, we believe the registered practice trading account serves two important functions. First, it allows the prospectivecustomer to evaluate our trading platform, tools and services. Second, for less experienced traders, it serves as an educational tool, providing the prospectivecustomers with the opportunity to try trading in a risk-free environment, without committing any capital. During this trial period, our customer service team isavailable to assist and educate the prospective customers. We also work with introducing brokers in order to expand our customer base. We work with a variety of different types of introducing brokers, ranging fromsmall, specialized firms that specifically identify and solicit customers interested in forex and CFD trading, to larger, more established financial servicesfirms. Introducing brokers direct customers to us in return for either a commission on each referred customer’s trading volume or a share of net revenuegenerated by each referred customer’s trading activity. In 2017 we began to roll out a global affiliate program pursuant to which third parties refer customer tous in exchange for a one-time payment. The affiliate program commenced in the United Kingdom and we intend to extend it to our other major markets.CompetitionThe market for our retail services is rapidly evolving and highly competitive. Our competitors vary by region in terms of regulatory status, breadth of productoffering, size and geographic scope of operations. Our main competitors during 2017 can be categorized as follows:8 Table of Contents•Regulated Forex Firm such as OANDA Corporation and FXCM. Like us, these firms have also expanded globally over the past several years, and weconsider them to be competitors in several of our key markets. In February 2017, FXCM was required to cease offering its services in the UnitedStates by the Commodities Futures Trading Commission and we acquired substantially all of the company's U.S.-domiciled customers. For moreinformation, please refer to Note 7 to our audited consolidated financial statements included in this Annual Report. •Global Multi-Asset Trading Firms, including firms such as Interactive Brokers, IG Group Holdings plc and CMC Group. These firms generally offer abroad set of asset classes and earn a significant percentage of their revenue from CFDs, forex and exchange-traded products.Our Institutional SegmentThrough our institutional segment, we provide a variety of services to institutional investors including electronic access to foreign exchange and preciousmetals via an ECN, agency execution services from our voice sales team through our registered swap dealer; trading on a registered swap execution facilityand prime-of-prime services in collaboration with the retail segment. For the year ended December 31, 2017, our institutional segment represented 9.8% ofour net revenue.In contrast to our retail segment, in our institutional segment, we act as agent between the principals to the transactions that are executed. We do not assumeany market or credit risk, as we earn commissions or commission equivalents (markup/markdown) for our services. Our institutional segment also facilitatesclient orders through riskless principal trades.Service OfferingsThrough the ECN platform, which is branded under “GTX,” we provide deep liquidity in spot and forward foreign exchange and precious metals to buy-sideand sell-side firms, including banks, brokers, hedge funds, Commodity Trading Advisors and asset managers. GTX’s centrally-cleared prime brokerage modelsupports true peer-to-peer trading capabilities and allows every GTX client to add market liquidity to the venue by posting real-time bids and offers, whilealso trading on other participants' bids and offers. For the year ended December 31, 2017, net revenue from our ECN business was 74% of the net revenue ofour institutional segment.Our prime-of-prime business, which we refer to as our GTX Direct offering, allows experienced traders who meet certain qualifications, but do not have acredit line with a prime broker, access to trading on the GTX ECN. Through GTX Direct, our clients deposit collateral with us and we make trades through theGTX trading platform on our clients’ behalf, earning a commission for each trade.The agency execution desk serves a broad range of participants across several asset classes, allowing clients to interact with the market based on their specificneeds and preferences. Our agency execution business is currently positioned on as a compliment to our ECN offering, providing bespoke hands-on servicefor clients wishing to execute more complex or structured transactions.Our swap execution facility, or SEF, offers electronic trading of non-deliverable forwards. We are in the process of on-boarding prime banks to serve as centralclearing hubs to facilitate this business.For the year ended December 31, 2017, net revenue from our agency execution business constituted 25% of the net revenue of our institutional segment.GTX is powered by software and intellectual property that we first licensed on an exclusive basis in 2010. After undertaking significant development andenhancement efforts, we acquired full ownership of the software and intellectual property in July 2014.Sales and MarketingWe have a direct sales team that is dedicated to building relationships with potential institutional customers and expanding our institutional business. Sinceits inception in 2010, our institutional business has expanded to include customers throughout the United States, Europe, and Asia.9 Table of ContentsCompetitionIn general, competition for business with institutional clients is based on a variety of factors, including technology, execution quality, client relationships,client service, cost and reputation.GTX competes with other firms offering electronic trading platforms, such as Nex Group, formerly ICAP, through its EBS offering; Thomson Reuters;Currenex, owned by State Street Bank; Hotspot, a subsidiary of CBOE Holdings, Inc.; Integral Development Corp.; FastMatch Inc.; 360T Trading Networks;and others.Our Futures SegmentOur futures segment offers execution and related services for exchange-traded futures and futures options on major U.S. and European exchanges. We clearour customers’ trades through our regulated FCM, GAIN Capital Group, LLC (“GCGL”). In 2014, we expanded our futures business by acquiring a majorityinterest in Global Asset Advisors, LLC (“GAA”), a Chicago-based futures brokerage firm which principally markets to and services clients under the DanielsTrading (“DTR”) brand. GAA is an introducing broker targeting retail and professional traders, primarily in equities and agricultural products. At the sametime, we also acquired a majority interest in Top Third Ag Marketing, LLC (“TT”), an introducing broker, which uses options-based hedging strategies tohelp clients manage the risks of agricultural production.Revenue in our futures segment is primarily generated through commissions earned on futures and futures options trades. Our futures segment represented12.3% of our net revenue for the year ended December 31, 2017.Advanced Trading PlatformOur futures segment provides customers an enhanced experience through our GAIN Trader proprietary trading platform. We have invested in high-speedconnectivity to provide access to over 30 global electronic exchanges, which allows us to deliver streaming quotes and high-speed executions. The GAINTrader platform has a robust suite of trading tools, including charting tools, custom alerts and indicators, as well as automated trading and risk managementtools. Our futures segment also provides Trade Desk Manager, a version of our GAIN Trader platform offered to other introducing brokers, which allows themto manage their customers’ accounts. In addition, we facilitate connection to our trading services through APIs from other front-end applications, and welicense a white label version of our GAIN Trader platform to select third parties.Risk ManagementIn our futures segment, we are exposed to credit risk as it relates to customer positions. If an adverse market move occurs and triggers an additional marginrequirement, we may be unable to collect the additional margin in a timely manner, or at all. In such a case, we would incur bad debt expense, which couldhave a material adverse effect on our results of operations. To mitigate this risk, we monitor all client accounts in near real time using multiple tool andprocesses designed to ensure that our client accounts are trading within their means.Sales and MarketingAs with our other segments, we seek to acquire futures customers as cost-efficiently as possible. Our principal source of new customers comes from a largenetwork of introducing brokers, In addition, sales leads are generated through seminars, online advertising and other media. In addition to our marketingefforts, we attract our futures segment customers through dedicated sales staff at GCGL, GAA and TT. These sales teams focus on a variety of sectors andprovide differentiated services to our customers.CompetitionOur futures segment competes for both introducing-broker generated business and direct client business. For introducing brokers, our primary competitors arethe limited number of FCMs that own and operate proprietary technology, including FC Stone, R.J. O’Brien, Rosenthal Collins Group, Interactive Brokers,and ADM Investor Services.The majority of our competitors for direct business are small, privately held firms like Allendale, Advance Trading, and Roach Ag Marketing; as well aslarger firms such as Interactive Brokers, TD Ameritrade and E*Trade Financial Corporation.Intellectual PropertyWe rely on a combination of trademark, copyright, trade secret and unfair competition laws in the United States and other jurisdictions to protect ourproprietary technology, intellectual property rights and our brands (e.g., FOREX.com, GAIN Capital, City Index and GTX).

To the extent that we wish to serve customers in a jurisdiction in which we determine licensing or registrationis required, we may also elect to direct such customers to a licensed white label or other partner, rather than pursuing licensing or registration ourselves.Though we conduct our business in a manner which we believe complies with applicable local law, regulators may assert authority over activities that theydeem to take place within the jurisdiction they regulate, and new laws, rules or regulations may be enacted that change the regulatory landscape and result innew, or clarify preexisting, registration or licensing requirements.The primary responsibility for ensuring that we maintain compliance with all applicable regulatory requirements is vested in our legal and compliancedepartments. In addition, our legal and compliance departments are responsible for our ongoing training and education programs, supervision of ourpersonnel required to be licensed by one or more of our regulators, review of sales, marketing and other communications and other related functions. Inaddition, our sales employees are licensed pursuant to applicable regulation.11 Table of ContentsU.S. RegulationIn the United States, the CFTC and the NFA regulate our forex and futures trading activities. Historically, the principal legislation covering our U.S. forexbusiness was the Commodity Exchange Act, which provides for federal regulation of all commodities and futures trading activities and requires all futuresand commodity options to be traded on organized exchanges. In recent years, as in the case of other companies in the financial services industry, our forexbusiness has been subject to increasing regulatory oversight. The CFTC Reauthorization Act, which grants the CFTC express authority to regulate the retailforex industry includes a series of rules which regulate various aspects of our business, including:•creating “retail foreign exchange dealers,” or RFEDs, a new regulated category of forex brokers focused on retail investors that are permitted to act ascounterparty to retail forex transactions;•imposing an initial minimum security deposit amount between 2.0% and 5.0%, depending on the pair, of the notional value for retail forextransactions in “major currency” pairs and between 5.0% and 20%, depending on the pair, of the notional value for retail forex transactions in "non-major currency";•providing that introducing brokers, money managers and fund managers must either (i) register with the CFTC and become members of the NFA orapply for an exemption from registration and (ii) meet the minimum net capital requirements applicable to futures and commodity optionsintroducing brokers or enter into a guarantee agreement with a CFTC-regulated forex dealer member and permitting only one such guaranteeagreement per introducing broker;•requiring that a risk disclosure statement be provided to every retail forex customer, including disclosure of the number of profitable andunprofitable non-discretionary accounts maintained by the forex broker during the four most recent calendar quarters; and•prohibiting RFEDs, FCMs and introducing brokers from including statements in sales and marketing materials that would appear to convey topotential retail forex customers that there is a guaranty against loss, and requiring that FCMs, RFEDs and introducing brokers provide retail forexcustomers with enhanced written disclosure statements that, among other things, inform customers of the risk of loss; andIn July 2010, Congress passed the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act. A number of significant provisionscontained in the law affect or will affect once implementing regulations are adopted by the appropriate federal agencies, our business. Specifically, the Dodd-Frank Act includes:•rules that, beginning in October 2010, require us to ensure that our customers residing in the United States have accounts open only with our NFA-member operating entity, GCGL;•amendments to the Commodity Exchange Act that, beginning on July 15, 2011, required essentially all retail transactions in any commodity otherthan foreign currency to be executed on an exchange, rather than OTC;•a requirement that federal banking regulators adopt new rules regarding the conduct and operation of retail forex businesses by banks; and•a requirement that the SEC adopt rules regarding the conduct and operation of retail forex businesses by broker-dealers.The Dodd-Frank Act also provides for additional regulation of swaps and security-based swaps, including some types of foreign exchange and metalsderivatives in which we engage. The Dodd-Frank Act requires the registration of swap dealers with the CFTC and imposes significant regulatory requirementson swap dealers and swap execution facilities. Effective February 27, 2013, GAIN GTX, LLC, ("GTX SEF") became provisionally registered with the CFTCand NFA as a swap dealer. Effective June 2016, GTX SEF, LLC became permanently registered with the CFTC as a swap execution facility, replacing thetemporary registration previously granted in April 2014. The CFTC and NFA have adopted, and may adopt, new rules including those more recently adoptedrequiring Retail Foreign Exchange Dealers to provide greater transparency about the cost associated with their forex transactions; required notification toNFA for FCMs that decide to offer customers the ability to trade any virtual currency futures product and monthly risk data reporting requirements for SwapDealers. Our operations in the U.S. are also subject to regulatory capital requirements that require various of our subsidiaries to maintain a minimum level ofnet capital relative to customer obligations. For more information, please see “Item 7. Management’s Discussion and Analysis of Financial Condition andResults of Operations - Liquidity and Capital Resources - Regulatory Capital Requirements.”U.S. Patriot Act and Anti-Money LaunderingLike other companies in the financial services industry, we are subject to a variety of statutory and regulatory requirements concerning our relationships withcustomers and the review and monitoring of their transactions. Specifically, we are subject to the Uniting and Strengthening America by ProvidingAppropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001, or the Patriot Act, which requires that we maintain a comprehensive anti-moneylaundering, or AML, program, a12 Table of Contentscustomer identification program, or CIP, designate an AML compliance officer, provide specified employee training and conduct an annual independentaudit of our AML program. Consistent with the Patriot Act, our CIP includes both documentary and non-documentary review and analysis of potentialcustomers. Under our CIP, we review each prospective customer’s identity internally and also contract with third-party firms that perform extensivebackground checks on each prospective customer, including through review of the U.S. Treasury Department’s Office of Foreign Assets and Control,Specially Designated Nationals and Blocked Persons lists. These procedures and tools, coupled with our periodic training, assist us in complying with thePatriot Act, as well as the CFTC’s and NFA’s applicable AML and CIP requirements.United Kingdom RegulationGAIN Capital U.K., Ltd. (“GCUK2”), Trade Facts, Ltd. (“Trade Facts”) and GAIN Capital Payments Ltd. are registered in the U.K. and are regulated by theFinancial Conduct Authority in respect of their trading activity. These U.K. Entities are required to comply with relevant U.K. and E.U. legislation andregulation. GAIN Capital-Forex.com U.K. Ltd.

Management’s Discussion and Analysis of Financial Condition and Results of Operations -Liquidity and Capital Resources - Regulatory Capital Requirements” for a discussion of minimum regulatory capital requirements applicable to our U.K.businesses.Client Money RulesGCUK2 is subject to the FCA’s client money rules by virtue of being authorized by the FCA to hold client money. Under these rules, we are required to:•maintain adequate segregation of client funds;•maintain adequate records in order to be able to meet future obligations when we hold client assets as collateral and be able to identify details ofthose assets to clients;•comply with custody rules when holding financial instruments (as defined by MiFID I) or other investments belonging to a client in the courseof our business, including the safeguarding of those investments and holding all dividends and fees (e.g., stock lending fees) in accordance withthe client money rules;•have adequate organizational arrangements in place to minimize the risk that client money may be paid for the account of a client whose moneyhas not yet been received by us;•undertake daily internal and external client money reconciliations; and•appoint an individual who is responsible for Client Asset Sourcebook, or CASS, oversight.Anti-Money Laundering and SanctionsAs in the U.S., we are subject to statutory and regulatory requirements concerning our relationships with customers and the review and monitoring of theirtransactions. Specifically, the U.K. Entities are subject to ongoing customer due diligence, or CDD, obligations under the Money Laundering Regulations2007, or MLR, and the FCA Handbook.The prescribed CDD measures require the U.K. Entities to (i) verify customer identity and understand the nature and purpose of the proposed relationship onthe basis of documents, data or information obtained from a reliable and independent source and (ii) review and monitor their customer’s transactions andactivities. The U.K. Entities are required to determine the extent of CDD measures required for each customer on a risk sensitive basis depending on the typeof customer, business relationship, product or transaction and we must be able to demonstrate that such measures are appropriate in view of the risks of moneylaundering and terrorist financing. Our procedures are based on the Joint Money Laundering Group’s Guidance for the U.K. Financial Sector, which providesguidance to firms for the determination of appropriate CDD measures.The FCA requires the U.K. Entities to have systems and controls in place to enable them to identify, assess, monitor and manage money laundering risk.Accordingly, we have the requisite systems and controls in place which are comprehensive and proportionate to the nature, scale and complexity of ouractivities. We provide appropriate training to our employees in relation to money laundering and retain documentation of our risk management policies andrisk profile in relation to money laundering. As required, we provide regular reports to our Money Laundering Reporting Officer, or MLRO, on the operationand effectiveness of these systems and controls, including details of our regular assessments of the adequacy of these systems and controls to ensure theircompliance with FCA requirements.Our systems and controls also include CDD and other measures to identify where customers and others with whom we transact may be subject to financialsanctions, including those initiated or adopted by the U.K. Treasury or the EU.13 Table of ContentsEMIRThe E.U. European Market Infrastructure Regulation (Regulation (EU) 648/2012), or EMIR, imposes requirements on entities that enter into any form ofderivative contract, including foreign exchange derivatives, and applies directly to firms in the E.U. and indirectly to non-E.U. firms that trade with E.U.firms. Accordingly, the U.K. Entities need to:•report all derivative contracts and their lifecycle events (concluded, modified and terminated) to which we are a party to a trade repository eitherby ourselves or through a third party;•keep all records relating to concluding of derivative contracts and any subsequent modification for 5 years;•comply with the risk management requirements for OTC bilateral derivatives, including portfolio reconciliation, portfolio compression, recordkeeping, dispute resolution and margining (these requirements began to be phased in starting in September 2016); and•clear through central counterparties all OTC derivatives which will be subject to the mandatory clearing obligation.Appropriateness assessmentsWhere firms offer “execution only” services for certain financial instruments which are deemed “complex”, E.U. Markets in Financial Instruments Directive(Directive 2004/39/EC), or MiFID I, requires firms to assess the appropriateness of those investments for retail clients. For this assessment, we are required tocollect information about our existing and potential clients’ knowledge and experience with regard to specific products and services, including:•the types of services, transactions and financial instruments with which the retail client is familiar;•the nature, volume, and frequency of the retail client’s transactions in financial instruments and the period over which they have been carriedout; and•the level of education, and profession or relevant former profession of the retail client or potential retail client.We are required to offer to a retail client or transact for them only those products that are deemed appropriate for their knowledge, experience and othercircumstances. If the retail client demands a product that has been assessed as inappropriate for the retail client’s circumstances by us, we may either refuse tooffer the product to the client, or allow them access to the product but we are required to give the retail client a warning that the product may be inappropriateto its circumstances. We are not required to undertake this analysis for professional clients as we are entitled to assume that a professional client has thenecessary knowledge and experience in order to understand the risks involved in relation to the particular products or services for which he has beenclassified as a professional client.MiFID IIMiFID I applied in the U.K. from November 2007 but has been recast into a new directive, the Markets in Financial Instruments Directive II (Directive2014/65/EU), or MiFID II, and a new regulation, the Markets in Financial Instruments Regulation (Regulation 600/2014), or MiFIR. The changesimplemented by MiFID II and MiFIR took effect on January 3, 2018.MiFID II:•expands the number of financial instruments for which firms are required to carry out an appropriateness assessment before providing anexecution only service to retail clients;•extends the pre- and post-trade transparency regime to derivatives traded on regulated markets, multi-lateral trading facilities, or MTFs, andorganized trading facilities, or OTFs;•expands transaction reporting to those financial instruments traded on MTFs, OTFs, and those financial instruments where the underlyinginstrument is traded on a Trading Venue; and•gives E.U. Member State regulators the new power to ban or restrict the marketing, distribution or sale of a financial instrument or types offinancial practice where there is a threat to investor protection, the orderly functioning and integrity of markets or to financial stability. TheEuropean Banking Authority and the European Securities and Markets Authority have similar powers to impose a ban on an EU-wide basis or inrelation to a particular E.U. Member State.Packaged Retail and Insurance-based Investment Products (PRIIPs)Regulation 1286/486 on key information documents for packaged retail and insurance-based investment products, or the PRIIPs Regulation, took effect inthe U.K. from January 1, 2018, reflecting a delay from the original implementation date of December 31, 2016. U.K. Entities now need to comply with thenew regime set out in the PRIIPs Regulation in relation to14 Table of ContentsPRIIPS that they manufacture, advise on or sell to retail clients. The FCA regards derivatives (including options, futures, and contracts for differences) asfalling within the definition of a PRIIP. The new regime requires us to provide retail clients with a standardized key information document, or KID, in goodtime before any transaction in derivatives is concluded or for transactions concluded by distance communications, after the transaction has taken place, butonly if it is not possible to provide the KID in advance and the client consents.ESMA’s Consultation Paper: ESMA35-43-904In January 2018, the European Securities and Markets Association, or ESMA, issued a consultation paper, referred to as ESMA35-43-904. In this paper,ESMA states that it is considering the possible use of its product intervention powers under Article 40 of MiFIR to address investor protection concerning themarketing, distribution and sale of CFDs and binary options to retail investors. These proposals include the use of enhanced risk disclosures, restrictionsupon the offering of promotional incentives to clients, mandatory margin close-out levels for retail clients and varying limitations on the opening leveragethat may be offered to clients; including an overall cap of 30 to 1 leverage for major currency pairs and lower leverage levels for other asset classes. Thecomment period for ESMA’s consultation expired in February 2018 and we cannot currently predict which, if any, of the proposed changes will beimplemented. The FCA have indicated that any U.K. policy measures covering similar topics would take in to account such ESMA measures once finalized.Other International RegulationWe have provided below a brief description of the key aspects of the regulations governing our operations in the jurisdictions outside of the U.S. and theUnited Kingdom in which we have registered with, or obtained a license from, the local regulator, as well as material regulatory developments affecting ourbusiness in other jurisdictions important to our business, including developments that have presented risks or uncertainties for our operations.JapanGAIN Capital Japan Co., Ltd., or GC Japan, is a registered Type I financial instruments business firm regulated by the Japan Financial Services Agency, orFSA, in accordance with Financial Instruments and Exchange Law (Law No. 25 of 1948, as amended).

RISK FACTORSRisks Related to Our BusinessOur revenue and profitability are influenced by trading volume and currency volatility, which are directly impacted by domestic and international marketand economic conditions that are beyond our control.During recent years, there has been significant disruption and volatility in the global financial markets. Our revenue is influenced by the general level oftrading activity in the global financial markets. Our revenue and operating results may vary significantly from period to period due primarily to movementsand trends in the world’s financial markets and to fluctuations in trading levels. We have generally experienced greater trading volume in periods of volatilemarkets. In the event we experience lower levels of market volatility, our revenue and profitability will likely be negatively affected. In addition, ourcustomer base is primarily comprised of individual retail customers who view trading in the markets we offer as an alternative investment class. If globaleconomic conditions limit the disposable income of our customers, our business could be materially adversely affected as our customers may choose tocurtail their trading, which could result in reduced customer trading volume and trading revenue.Like other financial services firms, our business and profitability are directly affected by elements that are beyond our control, such as economic and politicalconditions, broad trends in business and finance, changes in the volume of market transactions, changes in supply and demand for currencies, movements incurrency exchange rates, changes in the financial strength of market participants, legislative and regulatory changes, changes in the markets in which suchtransactions occur, changes in how such transactions are processed and disruptions due to terrorism, war or extreme weather events. Any one or more of thesefactors, or other factors, may adversely affect our business and results of operations and cash flows. A weakness in equity markets could result in reducedtrading activity by our customers and, therefore, could have a material adverse effect on our business, financial condition and results of operations and cashflows. As a result, period-to-period comparisons of our operating results may not be meaningful and our future operating results may be subject to significantfluctuations or declines.Our risk management policies and procedures may not be effective and may leave us exposed to unidentified or unexpected risks.We are dependent on our risk-management policies and the adherence to such policies by our staff. Our policies, procedures and practices used to identify,monitor and control a variety of risks, including risks related to human error, customer defaults, market movements, technology, fraud and money-laundering,are established and reviewed by the Risk Committee of our Board of Directors. Some of our methods for managing risk are discretionary by nature and arebased on internally developed controls and observed historical market behavior, and also involve reliance on standard industry practices. These methodsmay not adequately prevent losses, particularly as they relate to extreme market movements, which may be significantly greater than historical fluctuations inthe market. Our risk-management methods also may not adequately prevent losses due to technical errors if our testing and quality control practices are noteffective in preventing software or hardware failures. In addition, we may elect to adjust our risk-management policies to allow for an increase in risktolerance, which could expose us to the risk of greater losses. Our risk-management methods rely on a combination of technical and human controls andsupervision that are subject to error and failure. These methods may not protect us against all risks or may protect us less than anticipated, in which case ourbusiness, financial condition and results of operations and cash flows may be materially adversely affected.Our trading activities involve significant risks and unforeseen events could have a material adverse effect on our business, financial condition, results ofoperations and cash flows.We offer our clients access to a wide array of products, including forex, CFDs, spread bets, futures, futures options, OTC currency derivatives and gold andsilver spot trading products. Our trading activities in these various products involve significant risks.Through our retail and institutional forex trading activities, our principal sources of revenues and profits arise from the difference between the prices at whichwe buy and sell, or sell and buy, foreign currencies. We may incur trading losses for a variety of reasons, including:•price changes in foreign currencies;•lack of liquidity in foreign currencies in which we have positions; and17 Table of Contents•inaccuracies in our proprietary pricing mechanism, or rate engine, which evaluates, monitors and assimilates market data and reevaluates ouroutstanding currency quotes, and is designed to publish prices reflective of prevailing market conditions throughout the trading day.These risks may affect the prices at which we are able to sell or buy foreign currencies or may limit or restrict our ability to either resell foreign currencies thatwe have purchased or repurchase foreign currencies that we have sold.In addition, competitive forces often require us to match the breadth of quotes our competitors display and to hold varying amounts and types of foreigncurrencies at any given time. By having to maintain positions in certain currencies, we are subjected to a high degree of risk. We may not be able to managesuch risk successfully and may experience significant losses from such activities, which could have a material adverse effect on our business, financialcondition, results of operations and cash flows.All of the risks that pertain to our trading activities in the forex market also apply to our CFDs, spread bets, OTC currency derivatives and gold and silver spottrading products and any other products we may offer in the future. These risks include market risk, counterparty risk, liquidity risk, technology risk, third-party risk and risk of human error. In addition, unexpected events can occur that can result in great financial loss to us, including our inability to effectivelyintegrate new products into our existing trading platforms or our failure to properly manage the market risks associated with making markets for newproducts. The profit margins for these products may not be similar to the profit margins we have realized with respect to forex trading.In our futures segment, we are also exposed to debit/deficit risk with our clients for exchange-traded futures and options on futures. An adverse market moverelated to a client’s position may result in a debit balance, which, if we are unable to collect, would result in a bad debt expense. Such an expense could havea material adverse effect on our results of operations.The accounting method for convertible debt securities that may be settled in cash, such as our 4.125% Convertible Senior Notes due 2018, our 4.125%Convertible Senior Notes due 2020, and our 5.00% Convertible Senior Notes due 2022, could have a material effect on our reported financial results.Accounting Standards Codification 470-20, Debt with Conversion and Other Options, or ASC 470-20. ASC 470-20 requires an entity to separately accountfor the liability and equity components of convertible debt instruments whose conversion may be settled entirely or partially in cash (such as our 4.125%Convertible Senior Notes due 2018, our 4.125% Convertible Senior Notes due 2020, and our 5.00% Convertible Senior Notes due 2022) in a manner thatreflects the issuer’s economic interest cost for non-convertible debt. The liability component of the notes is initially valued at the fair value of a similar debtinstrument that does not have an associated equity component and is reflected as a liability in our Consolidated Balance Sheets in an amount equal to the fairvalue. The equity component of the notes is included in the additional paid-in capital section of our shareholders’ equity on our Consolidated BalanceSheets, and the value of the equity component is treated as original issue discount for purposes of accounting for the debt component. This original issuediscount is amortized to non-cash interest expense over the term of the notes, and, as a result, we record a greater amount of interest expense in currentperiods. Accordingly, we will report lower net income in our financial results than would have been recorded had we reflected only cash interest expense inour consolidated income statement because ASC 470-20 will require the interest expense associated with the notes to include both the current period’samortization of the original issue discount and the notes’ cash coupon interest, which could adversely affect our reported or future financial results, thetrading price of our common stock and the trading price of the notes.In addition, under certain circumstances, convertible debt instruments whose conversion may be settled entirely or partly in cash (such as our 4.125%Convertible Senior Notes due 2018, our 4.125% Convertible Senior Notes due 2020, and our 5.00% Convertible Senior Notes due 2022) are currentlyaccounted for using the treasury stock method. Under this method, the shares issuable upon conversion of the notes are not included in the calculation ofdiluted earnings per share unless the conversion value of the notes exceeds their principal amount at the end of the relevant reporting period. If theconversion value exceeds their principal amount, then, for diluted earnings per share purposes, the notes are accounted for as if the number of shares ofcommon stock that would be necessary to settle the excess, if we elected to settle the excess in shares, were issued. The accounting standards in the futuremay not continue to permit the use of the treasury stock method. If we are unable to use the treasury stock method in accounting for the shares, if any,issuable upon conversion of the notes, then our diluted earnings per share could be adversely affected.18 Table of ContentsServicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our businessto pay our substantial debt.Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including our 4.125% Convertible SeniorNotes due 2018, which were issued in November 2013, our 4.125% Convertible Senior Notes due 2020, which were issued in connection with our acquisitionof City Index, and our 5.00% Convertible Senior Notes due 2022, which were issued in August 2017, depends on our future performance, which is subject toeconomic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the futuresufficient to service our debt because of factors beyond our control. If we are unable to generate such cash flow, we may be required to adopt one or morealternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability torefinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of theseactivities or engage in these activities on desirable terms, which could result in a default on our debt obligations.Any disruption or corruption of our proprietary technology could have a material adverse effect on our business, financial condition and results ofoperations and cash flows.We rely on our proprietary technology to receive and properly process internal and external data. Any disruption in the proper functioning or any corruptionof our software or erroneous or corrupted data may cause us to make erroneous trades, accept customers from jurisdictions where we do not possess the properlicenses, authorizations or permits or require us to suspend our services, any of which could have a material adverse effect on our business, financialcondition and results of operations and cash flows.Systems failures could cause interruptions in our services or decreases in the responsiveness of our services, which could harm our business.If our systems fail to perform, we could experience disruptions in operations, slower response times or decreased customer satisfaction. Our ability to facilitatetransactions successfully and provide high quality customer service depends on the efficient and uninterrupted operation of our computer andcommunications hardware and software systems. These systems have in the past experienced periodic interruptions and disruptions in operations, which webelieve will continue to occur from time to time. Our systems 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. We do not have fully redundantcapabilities. While we currently maintain a disaster recovery plan, or DRP, which is intended to minimize service interruptions and secure data integrity, ourDRP may not work effectively during an emergency. Any systems failure that causes an interruption in our services or decreases the responsiveness of ourservices could impair our reputation, damage our brand name and materially adversely affect our business, financial condition and results of operations andcash flows.We may not be able to develop and adopt new technologies in a timely fashion, which could adversely impact our ability to compete in the markets inwhich we operate.Our success in the past has largely been attributable to our proprietary technology that has taken many years to develop. If our competitors develop moreadvanced technologies, we may be required to devote substantial resources to the development of more advanced technology to remain competitive. Ourindustry is characterized by rapidly changing technology, evolving industry standards and changing trading systems, practices and techniques. We may notbe able to keep up with these rapid changes in the future, develop new technology, realize a return on amounts invested in developing new technologies orremain competitive in the future.Security breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation tosuffer.In the ordinary course of our business, we collect and store sensitive data, including intellectual property, our proprietary business information and that of ourcustomers, and personally identifiable information of our customers and employees, in our data centers and on our networks. The secure processing,maintenance and transmission of this information is critical to our operations. Despite our security measures, we have from time to time experienced third-party cyberattacks as well as unintentional errors that can damage our systems or expose sensitive information, and our information technology andinfrastructure may be vulnerable to future attacks by hackers or compromised due to employee error, malfeasance or other disruptions, such as “distributeddenial of service” or similar cyberattacks. Any such event could compromise our networks and the information stored there could be accessed, publiclydisclosed, lost or stolen.19 Table of ContentsWhile our liability for known past events has not been material to our business, financial condition, results of operations or cash flows, any such access,disclosure or other loss of information could result in future legal claims or proceedings, liability under laws that protect the privacy of personal information,regulatory penalties, disruption of our operations and the services we provide to customers, damage to our reputation or a loss of confidence in our productsand services, any of which could adversely affect our business, financial condition, results of operations and cash flows. Although we maintain cyber riskinsurance, this insurance may not be sufficient to cover all of our losses from any future breaches of our systems.Products linked to cryptocurrencies could expose us to technology, regulatory and financial risks.We have recently begun offering derivative products linked to Bitcoin and other cryptocurrencies in certain jurisdictions, and intend to expand the types ofproducts offered, the associated types of cryptocurrencies and the jurisdictions in which the products are offered. The distributed ledger technologyunderlying cryptocurrencies and other similar financial assets is evolving at a rapid pace and may be vulnerable to cyberattacks or have other inherentweaknesses that are not yet apparent. We may be, or may become, exposed to risks related to cryptocurrencies or other financial products that rely ondistributed ledger technology through our facilitation of clients’ activities involving such financial products linked to distributed ledger technology.There is currently no broadly accepted regulatory framework for Bitcoin or other cryptocurrencies, and the regulation of cryptocurrencies is developing andchanging rapidly in the United States and other countries around the world. For example, in the United States, it is unclear whether many cryptocurrencies are“securities” under federal securities laws, and the implications for us if any of our products are linked to cryptocurrencies that are determined to be securitiescould be significant and adverse. In addition, some market observers have asserted that recent price increases in many cryptocurrency markets, such as that forBitcoin, indicate the existence of a “bubble,” and if markets for any cryptocurrencies linked to our products suffer severe declines, our customers couldexperience significant losses and we could lose their business.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 on a combination of trademark, copyright, trade secret and unfair competition laws in the United States and other jurisdictions in which we operate toprotect our proprietary technology, intellectual property rights and our brands. We do not have any patents. While we rigorously control access to ourproprietary technology and enter into confidentiality and invention assignment agreements with our employees, consultants and other third parties, it ispossible that third parties may copy or otherwise obtain and use our proprietary technology without authorization or otherwise infringe on our rights. Suchunauthorized use and infringement would undermine the competitive benefits offered by our proprietary technology and could adversely impact our businessand results of operations.We also license or are permitted to use intellectual property or technologies owned by others. In the event such intellectual property or technology becomesmaterial to our business, the loss of our license or our inability to otherwise continue use of such technologies would have a material adverse effect on ourbusiness. We may also face claims of infringement that could interfere with our ability to use technology that is material to our business operations.Attrition of customer accounts and failure to attract new accounts in a cost-effective manner could have a material adverse effect on our business,financial condition and results of operations and cash flows.Our customer base is primarily comprised of individual retail customers who generally trade with us for short periods. Although we offer products and tailoredservices designed to educate, support and retain our customers, our efforts to attract new customers or reduce the attrition rate of our existing customers maynot be successful. If we are unable to maintain or increase our customer retention rates or generate a substantial number of new customers in a cost-effectivemanner, our business, financial condition and results of operations and cash flows would likely be adversely affected. Although we have spent significantfinancial resources on sales and marketing expenses and related expenses and plan to continue to do so, these efforts may not be cost-effective at attractingnew customers. In particular, we believe that rates for desirable advertising and marketing placements, including online, search engine, print and televisionadvertising, are likely to increase in the foreseeable future, and we may be disadvantaged relative to our larger competitors in our ability to expand ormaintain our advertising and marketing commitments. Additionally, our sales and marketing methods are subject to regulation by the Commodity FuturesTrading Commission, or CFTC, and National Futures Association, or NFA, in the United States, the Financial Conduct Authority, or FCA, in the UnitedKingdom and by other regulators in other jurisdictions. The rules and regulations of these organizations impose specific limitations on our sales methods,advertising and marketing. If we do not achieve our advertising objectives, our profitability and growth may be materially adversely affected. 20 Table of ContentsWe are subject to litigation risk which could adversely affect our reputation, business, financial condition and results of operations and cash flows.Many aspects of our business involve risks that expose us to potential liability under federal, state and local laws, both in the U.S. and in the otherjurisdictions in which we operate, as well as the rules and enforcement efforts of our regulators and self-regulatory organizations worldwide. These risksinclude, among others, disputes over trade terms with customers and other market participants, customer losses resulting from system delay or failure andcustomer claims that we or our employees executed unauthorized transactions, made materially false or misleading statements or lost or diverted customerassets in our custody. We may also be subject to regulatory investigation and enforcement actions seeking to impose significant fines or other sanctions,which in turn could trigger civil litigation for our previous operations that may be deemed to have violated applicable rules and regulations in one or morejurisdictions.The volume of claims and the amount of damages and fines claimed in litigation and regulatory proceedings against financial services firms has beenincreasing and may continue to increase. The amounts involved in the trades we execute, together with rapid price movements in our currency pairs, canresult in potentially large damage claims in any litigation resulting from such trades. Dissatisfied customers, regulators or self-regulatory organizations maymake claims against us regarding the quality of trade execution, improperly settled trades, mismanagement or even fraud, and these claims may increase asour business expands.Litigation may also arise from disputes over the exercise of our rights with respect to customer accounts and collateral. Although our customer agreementsgenerally provide that we may exercise such rights with respect to customer accounts and collateral as we deem reasonably necessary for our protection, ourexercise of these rights may lead to claims by customers that we did so improperly.We may also have to rely on litigation to enforce our intellectual property rights, protect our trade secrets, determine the validity and scope of the proprietaryrights of others or defend against claims of infringement or invalidity. Even if we prevail in any litigation or enforcement proceedings against us, we couldincur significant legal expenses defending against the claims, even those without merit. Moreover, because even claims without merit can damage ourreputation or raise concerns among our customers, we may feel compelled to settle claims at significant cost. The initiation of any claim, proceeding orinvestigation against us, or an adverse resolution of any such matter, could have a material adverse effect on our reputation, business, financial condition andresults of operations and cash flows.We may be subject to customer litigation, financial losses, regulatory sanctions and harm to our reputation as a result of employee misconduct or errorsthat are difficult to detect and deter.There have been a number of highly publicized cases involving fraud or other misconduct by employees of financial services firms in recent years. Ouremployees could execute unauthorized transactions for our customers, use customer assets improperly or without authorization, carry out improper activitieson behalf of customers or use confidential customer or company information for personal or other improper purposes, as well as improperly record orotherwise try to hide improper activities from us.In addition, employee errors, including mistakes in executing, recording or reporting transactions for customers, may cause us to enter into transactions thatcustomers disavow and refuse to settle. Employee errors expose us to the risk of material losses until the errors are detected and the transactions are unwoundor reversed. The risk of employee error or miscommunication may be greater for products that are new or have non-standardized terms. Further, such errorsmay be more likely to occur following any acquisitions during the integration of or migration from technological systems. Misconduct by our employees orformer employees could subject us to financial losses or regulatory sanctions and seriously harm our reputation. It may not be possible to detect or deteremployee misconduct, and the precautions we take to prevent and detect this activity may not be effective in all cases. Our employees may also commit goodfaith errors that could subject us to financial claims for negligence or otherwise, as well as regulatory actions.Misconduct by employees of our customers can also expose us to claims for financial losses or regulatory proceedings when it is alleged we or our employeesknew or should have known that an employee of our customer was not authorized to undertake certain transactions. Dissatisfied customers can make claimsagainst us, including claims for negligence, fraud, unauthorized trading, failure to supervise, breach of fiduciary duty, employee errors, intentionalmisconduct, unauthorized transactions by persons associated with us or failures in the processing of transactions.21 Table of ContentsOur customer accounts may be vulnerable to identity theft and credit card fraud.Credit card issuers have adopted credit card security guidelines as part of their ongoing efforts to prevent identity theft and credit card fraud. We continue towork with credit card issuers to ensure that our services, including customer account maintenance, comply with these rules. When there is unauthorizedaccess to credit card data that results in financial loss, there is the potential that we could experience reputational damage and parties could seek damagesfrom us.If our reputation is harmed, or the reputation of the online financial services industry as a whole is harmed, our business, financial condition and results ofoperations and cash flows may be materially adversely affected.Our ability to attract and retain customers and employees may be adversely affected if our reputation is damaged. If we fail, or appear to fail, to deal withissues that may give rise to reputation risk, our business prospects could be materially adversely affected. These issues include, but are not limited to,appropriately dealing with potential conflicts of interest, legal and regulatory requirements, ethical issues, money-laundering, privacy, client data protection,record keeping, sales and trading practices, and the proper identification of the legal, credit, liquidity, and market risks inherent in our business. Failure toappropriately address these issues could also give rise to additional legal risk to us, which could, in turn, increase the size and number of claims and damagesasserted against us or subject us to regulatory enforcement actions, fines and penalties. Any such sanctions could materially adversely affect our reputation,thereby reducing our ability to attract and retain customers and employees.In addition, our ability to attract and retain customers may be adversely affected if the reputation of the online financial services industry as a whole or theforex industry is damaged. In recent years, a number of financial services firms have suffered significant damage to their reputations from highly publicizedincidents that in turn resulted in significant and in some cases irreparable harm to their business. A perception of instability within the online financialservices industry also could materially adversely affect our ability to attract and retain customers.The loss of our key employees could materially adversely affect our business, including our ability to grow our business.Our key employees, including Glenn Stevens, our chief executive officer, have significant experience in the forex industry and have made significantcontributions to our business. In addition, other senior employees have made significant contributions to our business. Our continued success is dependentupon the retention of these and other key executive officers and employees, as well as the services provided by our trading staff, technology andprogramming specialists and a number of other key managerial, marketing, planning, financial, technical and operations personnel. The loss of such keypersonnel could have a material adverse effect on our business. In addition, our ability to grow our business is dependent, to a large degree, on our ability toretain such employees. The industries in which we operate are highly competitive and we may be adversely affected if we are unable to compete effectively.The OTC derivatives market served by our retail segment is rapidly evolving and characterized by intense competition and evolving domestic and globalregulatory oversight and rules. Tighter spreads and increased competition could make our business less profitable. Our prospects may be materially adverselyaffected by our ability to adapt to these changes and effectively manage the risks, expenses and difficulties frequently encountered in the operation of abusiness in a rapidly evolving industry. We face similar competitive pressure in our institutional and futures segments.In addition, our competitors include sophisticated institutions which have larger customer bases, more established name recognition and substantially greaterfinancial, marketing, technological and personnel resources than we do. These advantages may enable them, among other things, to:•develop products and services that are similar to ours, or that are more attractive to customers than ours in one or more of our markets;•provide products and services we do not offer;•provide execution and clearing services that are more rapid, reliable, efficient or less expensive than ours;•offer products and services at prices below ours to gain market share and to promote other businesses, such as forex options, futures, listed securities,CFDs, precious metals and OTC derivatives;•adapt at a faster rate to market conditions, new technologies and customer demands;•offer better, faster and more reliable technology;•outbid us for desirable acquisition targets;•more efficiently engage in and expand existing relationships with strategic alliances;22 Table of Contents•market, promote and sell their products and services more effectively; and•develop stronger relationships with customers.These competitors, including commercial and investment banking firms, may have access to capital in greater amounts and at lower costs than we do, and,therefore, may be better able to respond to changes in the industries in which we operate, to compete for skilled professionals, to finance acquisitions, to fundinternal growth and to compete for market share generally. Access to capital is critical to our business to satisfy regulatory obligations and liquidityrequirements. Among other things, access to capital determines our creditworthiness, which if perceived negatively in the market could materially impair ourability to attract customer assets. Access to capital also determines the degree to which we can expand our operations. Therefore, if we are unable to maintainor increase our capital on competitive terms, we could be at a significant competitive disadvantage, and our ability to maintain or increase our revenue andearnings could be materially impaired. Also, new or existing competitors in our markets could make it difficult for us to maintain our current market share orincrease it in desirable markets. Increased competition could also result in narrowing bid/offer spreads, which could materially adversely affect our business,financial condition and results of operations and cash flows. Any reduction in revenues without a commensurate reduction in expenses would decrease ourprofitability. We may not be able to compete effectively against these firms, particularly those with greater financial resources, and our failure to do so couldmaterially and adversely affect our business, financial condition and results of operations and cash flows.We may be unable to successfully execute our growth strategy.As we continue to seek to grow our business, we intend to execute a growth strategy that involves a number of different initiatives designed to organicallygrow our product offering and customer base, increase operational efficiency, reduce revenue volatility and rationalize and leverage our global brands, whilestill selectively pursuing acquisition opportunities. We also intend to continue to expand and upgrade the reliability and scalability of our transactionprocessing systems, network infrastructure and other aspects of our proprietary technology. We may not be able to successfully execute all or any of theseinitiatives, and the results may vary from our expectations. Further, even if these initiatives are successful, we may not be able to expand and upgrade ourtechnology systems and infrastructure to accommodate increases in our business activity in a timely manner, which could lead to operational breakdownsand delays, loss of customers, a reduction in the growth of our customer base, increased operating expenses, financial losses, increased litigation or customerclaims, regulatory sanctions or increased regulatory scrutiny. In addition, we will need to continue to attract, hire and retain highly skilled and motivatedexecutives and employees to both execute our growth strategy and to manage the resulting growth effectively.We may be unable to respond to customers’ demands for new services and products and our business, financial condition and results of operations andcash flows may be materially adversely affected.The market for Internet-based and mobile trading is characterized by:•changing customer demands;•the need to enhance existing services and products or introduce new services and products;•evolving industry practices; and•rapidly evolving technology solutions.New services and products provided by our competitors may render our existing services and products less competitive. Our future success will depend, inpart, on our ability to respond to customers’ demands for new services and products on a timely and cost-effective basis and to adapt to address theincreasingly sophisticated requirements and varied needs of our customers and prospective customers. We may not be successful in developing, introducingor marketing new services and products. In addition, our new service and product enhancements may not achieve market acceptance. Any failure on our partto anticipate or respond adequately to customer requirements or changing industry practices, or any significant delays in the development, introduction oravailability of new services, products or service or product enhancements could have a material adverse effect on our business, financial condition and resultsof operations and cash flows.Our international operations present special challenges and our failure to adequately address such challenges or compete in these markets, either directlyor through joint ventures with local firms, could have a material adverse effect on our business, financial condition and results of operations and cashflows.In 2017, we generated approximately 72.7% of our retail segment trading volume from customers outside the United States. Expanding our business in newmarkets is an important part of our growth strategy. Due to certain cultural, regulatory and other challenges relevant to those markets, however, we may be ata competitive disadvantage in those regions relative to local firms or to international firms that have a well-established local presence. These challengesinclude:23 Table of Contents•less developed or mature local technological infrastructure and higher costs, which could make our products and services less attractive or accessiblein emerging markets;•difficulty in complying with the diverse regulatory requirements of multiple jurisdictions, which may be more burdensome, not clearly defined andsubject to unexpected changes, potentially exposing us to significant compliance costs and regulatory penalties;•less developed and established local financial and banking infrastructure, which could make our products and services less accessible;•reduced protection of intellectual property rights;•inability to enforce contracts;•difficulties and costs associated with staffing and managing foreign operations, including reliance on newly hired local personnel;•tariffs and other trade barriers;•currency and tax laws that may prevent or restrict the transfer of capital and profits among our various operations around the world; and•time zone, language and cultural differences among personnel in different areas of the world.In addition, in order to be competitive in these local markets, or in some cases because of restrictions on the ability of foreign firms to do business locally, wemay seek to operate through joint ventures with local firms. Doing business through joint ventures may limit our ability to control the conduct of thebusiness and could expose us to reputational and greater operational risks. We may also face intense competition from other international firms overrelatively scarce opportunities for market entry. Given the intense competition from other international brokers that are also seeking to enter these newmarkets, we may have difficulty finding suitable local firms willing to enter into the kinds of relationships with us that we may need to gain access to thesemarkets. This competition could make it difficult for us to expand our business internationally as planned.If our operating subsidiaries are unable to pay us dividends when needed, we may be unable to satisfy our obligations when they arise.As a holding company, nearly all of our funds generated from operations are generated by our operating subsidiaries. Historically, we have accessed thesefunds through receipt of dividends from these subsidiaries. Some of our subsidiaries are subject to regulation and requirements of various regulatory bodies,including the CFTC and NFA in the United States, the FCA in the United Kingdom, the FSA, METI and MAFF in Japan, the SFC in Hong Kong, IIROC andthe Ontario Securities Commission, or OSC, in Canada, MAS in Singapore, ASIC in Australia, and the CIMA in the Cayman Islands, relating to liquidity andcapital standards, which may have the effect of limiting funds available for the payment of dividends to the holding company. Accordingly, if our operatingsubsidiaries are unable to pay us dividends and make other payments to us when needed, due to regulatory restrictions or otherwise, we may be unable tosatisfy our obligations when they arise.Our acquisition strategy may result in significant transaction expenses, integration and consolidation risks and risks associated with entering newmarkets, and we may be unable to profitably operate our consolidated company.We have engaged in, and intend to continue to pursue, acquisitions of other businesses as part of our strategy to increase the range of products that we offer,especially into non-forex products, and to expand our businesses into new markets and geographies. Such acquisitions involve significant transactionexpenses, including, but not limited to, fees paid to legal, financial, tax and accounting advisors, filing fees and printing costs. Acquisitions also present risksassociated with offering new products or entering new markets and integrating the acquired companies. Other areas where we may face risks include:•diversion of management time and focus from operating our business to address challenges that may arise in integrating the acquired business;•transition of operations, users and customers onto our existing platforms or onto platforms of the acquired company;•failure to successfully further develop the acquired business;•failure to realize anticipated operational or financial synergies;•implementation or remediation of controls, procedures, and policies at the acquired company;•in the case of foreign acquisitions, the need to integrate operations across different cultures and languages and to address the particular economic,currency, political, and regulatory risks associated with specific countries;•liability for activities of the acquired company before the acquisition, such as violations of laws, commercial disputes, tax liabilities, and otherknown and unknown liabilities; and•integration of the acquired business’ accounting, human resource and other administrative systems, and coordination of trading and sales andmarketing functions. 24 Table of ContentsFuture acquisitions could also result in dilutive issuances of our equity securities, the incurrence of debt, amortization expenses, impairment of goodwill andpurchased long-lived assets, and restructuring charges, any of which could harm our financial condition or results. Additionally, any new businesses that wemay acquire, once integrated with our existing operations, may not produce expected or intended results. Our failure to address these risks or other problemsencountered in connection with our future acquisitions could cause us to fail to realize the anticipated benefits of such acquisitions or incur unanticipatedliabilities, any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows.Risks Related to RegulationFailure to comply with the rapidly evolving laws and regulations governing our businesses may result in regulatory agencies taking action against us,which could significantly harm our business.Substantially all of our operations are conducted through subsidiaries that are regulated by governmental bodies or self-regulatory organizations. Many ofthe regulations we are governed by are intended to protect the public, our customers and the integrity of the markets, and not necessarily our shareholders.Among other things, we are subject to regulation with regard to:•sales and marketing activities, including our interaction with, and solicitation of, customers;•trading practices, including the types of investment products we may offer;•the methods by which customers can fund accounts with us, including the recently implemented NFA ban on the use of credit cards to fund accountsin the United States;•treatment of customer assets, including custody, control, safekeeping and, in certain countries, segregation of our customer funds and securities;•maintaining specified minimum amounts of capital and limiting withdrawals of funds from our regulated operating subsidiaries;•continuing education requirements for our employees;•anti-money laundering practices;•record keeping and reporting; and•supervision regarding the conduct of directors, officers and employees.Compliance with these regulations is complicated, time consuming and expensive. Our ability to comply with all applicable laws and regulations isdependent in large part on our internal legal and compliance functions, as well as our ability to attract and retain qualified personnel, which we may not beable to do. Regulators and self-regulatory organizations broadly oversee the conduct of our business and several perform regular examinations of ouroperations to monitor our compliance with applicable laws and regulations. If a regulator finds that we have failed to comply with applicable rules andregulations, we may be subject to censure, fines, cease-and-desist orders, suspension of our business, removal of personnel, civil litigation or other sanctions,including, in some cases, increased reporting requirements or other undertakings, revocation of our operating licenses or criminal conviction. In addition, wecould incur significant legal expenses in defending ourselves against and resolving actions or investigations by such regulatory agencies. An adverseresolution of any future actions or investigations by such regulatory agencies against us could result in a negative perception of our company and cause themarket price of our common stock to decline or otherwise have a material adverse effect on our business, financial condition, results of operations and cashflows.Regulatory changes in the jurisdictions in which we operate may disrupt our operations or require us to comply with additional regulatory requirements.Recently, the legislative and regulatory environment in which we operate has undergone significant changes, and U.S. and foreign regulators have expressedtheir intention to review existing regulation in a number of areas. For example, In January 2018, the European Securities and Markets Association, or ESMA,issued a consultation paper, referred to as ESMA35-43-904. In this paper, ESMA states that it is considering the possible use of its product interventionpowers under Article 40 of MiFIR to address investor protection concerning the marketing, distribution and sale of CFDs and binary options to retailinvestors. These proposals include the use of enhanced risk disclosures, restrictions upon the offering of promotional incentives to clients, mandatory marginclose-out levels for retail clients and applying an overall cap of 30-to-1 leverage for major currency pairs and lower leverage levels for other asset classes. TheFCA have indicated that any U.K. policy measures covering similar topics would take in to account such ESMA measures once finalized. In addition, theregulators in a number of European countries, such as France and Belgium, have already adopted rules and regulations that prohibit or limit offering,advertising and promoting leveraged derivative products such as CFDs, and other regulators may follow suit. In Japan, the FSA has proposed25 Table of Contentsnew rules that would reduce the maximum leverage that brokers can offer to 10-to-1 from the current limit of 25-to-1. In China, recent activity suggests thatthe Chinese government may be looking to adopt specific regulations governing trading of foreign exchange and CFD products. Our ability to expand ourpresence in various jurisdictions throughout the world will depend on the nature of future changes to the regulatory environment and our ability to continueto comply with evolving requirements. Any of these new regulatory developments, alone or in combination, could have a material adverse effect on ourbusiness and profitability.As we operate in many jurisdictions without local registration, licensing or authorization, we may be subject to possible enforcement action and sanctionfor our operations in such jurisdictions if our operations are determined to have violated regulations in those jurisdictions. Further, our growth may belimited by various restrictions and we remain at risk that we may be required to cease operations if we become subject to regulation by local governmentbodies.For the year ended December 31, 2017, although a majority of our retail trading volume was attributable to customers resident in a jurisdiction where we orour white label partners are licensed, regulated or deal with customers cross-border in a manner that we believe does not require us to be regulated in thatjurisdiction, a portion of our retail trading volume was attributable to customers in jurisdictions in which we or our white label partners are not currentlylicensed or authorized by the local government or applicable self-regulatory organization. We determine the nature and extent of services we can offer andthe manner in which we conduct our business in the various jurisdictions in which we serve customers based on a variety of factors, including legal advicereceived from local counsel, our review of applicable U.S. and local laws and regulations and, in some cases, our discussions with local regulators. In cases inwhich we operate in jurisdictions based on local legal advice, we are exposed to the risk that our legal and regulatory analysis is subsequently determined bya local regulatory agency or other authority to be incorrect and that we have not been in compliance with local laws or regulations, including local licensingor authorization requirements, and to the risk that the regulatory environment in a jurisdiction may change, including in a circumstance where laws orregulations or licensing or authorization requirements that previously were not enforced become subject to enforcement.In jurisdictions in which we are not licensed or authorized, we may be subject to a variety of restrictions regarding the manner in which we conduct ourbusiness or serve customers, including restrictions on:•our sales and marketing activities;•the use of a website specifically targeted to potential customers in a particular country;•the minimum income level or financial sophistication of potential customers we may contact;•our ability to have a physical presence in a particular country; or•the types of services we may offer customers physically present in each country.These restrictions may limit our ability to grow our business in any such jurisdiction or may result in increased overhead costs or degradation in our servicesin that jurisdiction. Consequently, we cannot assure you that our international expansion plans will be achieved.We may be subject to possible enforcement action and penalties if we are determined to have previously offered, or currently offer, our services in violationof applicable laws and regulations in any of the markets in which we serve customers. In any such case, we may be required to cease the conduct of ourbusiness with customers in one or more jurisdictions. We may also determine that compliance with the laws or licensing, authorization or other regulatoryrequirements for continuing the business in one or more jurisdictions are too onerous to justify making the necessary changes. In addition, any such eventcould negatively impact our relationship with the regulators or self-regulatory organizations in the jurisdictions where we are subject to regulation.We are required to maintain high levels of capital, which could constrain our growth and subject us to regulatory sanctions.Our regulators have stringent rules requiring that we maintain specific minimum levels of regulatory capital in our operating subsidiaries. In the UnitedStates, as a Futures Commission Merchant, or FCM, and a Retail Forex Exchange Dealer, or RFED, we are required to maintain adjusted net capital of $20.0million plus 5.0% of the amount of retail customer liabilities over $10.0 million, plus 10% of all liabilities owed to eligible contract participantcounterparties acting as a dealer that are not an affiliate. On a worldwide basis, as of December 31, 2017, we were required to maintain approximately $112.9million in minimum capital in the aggregate across all jurisdictions. Regulators continue to evaluate and modify regulatory capital requirements from time totime in response to market events and to improve the stability of the international financial system. Additional revisions to this framework or new capitaladequacy rules applicable to us may be proposed and ultimately adopted, which could further increase our minimum capital requirements in the future.26 Table of ContentsEven if regulators do not change existing regulations or adopt new ones, our minimum capital requirements will generally increase in proportion to the sizeof the business conducted by our regulated subsidiaries. As a result, we will need to increase our regulatory capital in order to expand our operations andincrease our revenue, and our inability to increase our capital on a cost-efficient basis could constrain our growth. In addition, in many cases, we are notpermitted to withdraw regulatory capital maintained by our subsidiaries without prior regulatory approval or notice, which could constrain our ability toallocate our capital resources most efficiently throughout our global operations. In particular, these restrictions could adversely affect our ability to withdrawfunds needed to satisfy our ongoing operating expenses, debt service and other cash needs and could affect any future decision by our Board of Directorsregarding the payment of our quarterly dividends. Regulators monitor our levels of capital closely and we are required to report the amount of regulatorycapital we maintain to our regulators on a regular basis, and must report any deficiencies or material declines promptly. While we expect that our currentamount of regulatory capital will be sufficient to meet anticipated short-term increases in requirements, any failure to maintain the required levels ofregulatory capital, or to report any capital deficiencies or material declines in capital could result in severe sanctions, including fines, censure, restrictions onour ability to conduct business and revocation of our registrations. The imposition of one or more of these sanctions could ultimately lead to our liquidation,or the liquidation of one or more of our operating subsidiaries.Interpretation of corporate tax laws and regulations and changes in such laws and regulations, as well as adverse determinations regarding theapplication of such laws and regulations, could adversely affect our earnings.We are subject to the income tax laws of the U.S., its states and municipalities and those of the foreign jurisdictions in which we have significant businessoperations. These tax laws are complex and may be subject to different interpretations. We must make judgments and interpretations about the application ofthese inherently complex tax laws when determining the provision for income taxes and must also make estimates about when in the future certain itemsaffect taxable income in the various tax jurisdictions. Disputes over interpretations of the tax laws may be settled with the taxing authority upon examinationor audit. In addition, changes to the Internal Revenue Code, administrative rulings or court decisions could increase our provision for income taxes andreduce our earnings.On December 22, 2017, President Trump signed into law P.L. no 115-97 “Tax Cuts and Jobs Act” which includes a broad range of tax law changes affectingbusinesses, including corporate tax rates, business deductions, and international tax provisions. As the law is new and administrative tax regulations havenot yet been made available with respect to many of the provisions in this new law, it is uncertain as to how these new provisions will be interpreted andapplied by the Internal Revenue Service and what impact this law will have on our business. Servicing customers via the Internet may require us to comply with the laws and regulations of each country in which we are deemed to conduct business.Failure to comply with such laws may negatively impact our financial results.Since our services are available over the Internet in foreign countries and we have customers residing in foreign countries, foreign jurisdictions may requireus to qualify to do business in their country. We believe that the number of our customers residing outside of the United States will continue to increase overtime. We are required to comply with the laws and regulations of each country in which we conduct business, including laws and regulations currently inplace or which may be enacted related to Internet services available to the residents of each country from service providers located elsewhere. For example,the Cyprus Securities and Exchange Commission recently announced that it will require any registered investment firm in Cyprus that wishes to offerproducts to customers offered in another country to provide evidence of its authorization to offer products in that other country. If one of our regulators wereto adopt a similar requirement, we could be subject to increased regulatory compliance costs or may be required to modify our business and operations. Anyfailure to develop effective compliance and reporting systems could result in regulatory penalties in the applicable jurisdiction, which could have a materialadverse effect on our business, financial condition and results of operations and cash flows.Procedures and requirements of the Patriot Act and other anti-money laundering and know your customer regulations may expose us to significant costsor penalties.As participants in the financial services industry, we are, and our subsidiaries are, subject to numerous laws and regulations, including the United StatesPatriot Act, that require that we know our customers and monitor transactions for suspicious financial activities. The cost of complying with the Patriot Actand similar laws and regulations is significant. We face the risk that our policies, procedures, technology and personnel directed toward complying with theselaws and regulations are insufficient and that we could be subject to significant criminal and civil penalties due to noncompliance. Such penalties could havea material adverse effect on our business, financial condition and results of operations and cash flows.27 Table of ContentsRisks Related to Third PartiesIf we lose access to our prime brokers and other liquidity providers, we may be unable to provide competitive trading services, which will materiallyadversely affect our business, financial condition and results of operations and cash flows.We rely on third-party financial institutions to provide us with market liquidity. We maintain relationships with a large network of liquidity providers,including established global prime brokers such as J.P. Morgan, Citibank and UBS. We depend on these relationships, particularly those with our primebrokers, for our access to a pool of liquidity to ensure that we are able to execute our customers’ trades in the products we offer at the notional amounts ourcustomers request. These liquidity providers, although under contract with us, may terminate our arrangements at any time. If we were to experience adisruption in the services provided by a liquidity provider, particularly one of our prime brokers, due to a financial, technical or other adverse development,our business could be materially adversely affected to the extent that we are unable to transfer positions and margin balances to another liquidity providerthat allows us to offer competitive trading services in a timely fashion. In the event of the insolvency of one of our prime broker or other liquidity providers,we might not be able to recover any or all of the funds we have on deposit with such entity since we will be among the entity’s unsecured creditors. In theevent that we no longer have access to the levels of liquidity that we currently have, we may be unable to provide competitive trading services, which wouldmaterially adversely affect our business, financial condition and results of operations and cash flows.A systemic market event that impacts the various market participants with whom we interact could have a material adverse effect on our business,financial condition and results of operations and cash flows.We interact with various third parties through our relationships with our liquidity providers, white label partners and introducing brokers. Some of thesemarket participants could be overleveraged. In the event of sudden, large market price movements, such market participants may not be able to meet theirobligations to brokers who, in turn, may not be able to meet their obligations to their counterparties. As a result, a system collapse in the financial systemcould occur, which would have a material adverse effect on our business, financial condition and results of operations and cash flows.We are subject to risk of default by financial institutions that hold our funds and our customers’ funds.We have significant deposits of our own funds and our customers' funds with banks and other financial institutions, including liquidity providers. In theevent of the insolvency of one of these financial institutions, we might not be able to fully recover the assets we have deposited since we will be among theinstitution’s unsecured creditors. As a result, our business could be materially adversely affected by the loss of these funds.Retail Forex customer funds deposited with us in the United States are not permitted to be segregated from our own funds for purposes of applicableCFTC, NFA, bankruptcy or insolvency laws and regulations, meaning such funds may be at risk of default if we were to become insolvent.Pursuant to CFTC and NFA regulations for our U.S.-regulated subsidiaries, retail forex customer funds deposited with us are not permitted to be segregatedfrom our own funds for purposes of applicable CFTC, NFA, bankruptcy and insolvency laws and regulations. Although we are required to designate andreport specific depository accounts as accounts holding assets to cover our obligations to retail forex customers; our customers’ funds may be aggregatedwith our own for these purposes. In the event we were to become insolvent, our customers may be unable to fully recover the funds they have deposited withus, as they will be among our unsecured creditors, and the extent to which these funds will be entitled to insurance by the Federal Deposit InsuranceCorporation is uncertain.We are subject to credit risk in that a customer’s losses may exceed the amount of cash in their account.Our trading operations require a commitment of our capital and involve risk of loss because of the potential that a customer’s losses may exceed the amountof cash in their account. Our margin policy allows customers to leverage their account balances by trading notional amounts that may be significantly largerthan their cash balances. We mark our customers’ accounts to market each time a price in their portfolio changes. While this allows us to closely monitor eachcustomer’s exposure, it does not guarantee our ability to eliminate negative customer account balances prior to an adverse price change or other marketevents. Although we have the ability to alter our margin requirements without prior notice to our customers, this may not eliminate the risk that our access toliquidity becomes limited or market conditions, including price volatility and liquidity constraints, change faster than our ability to modify our marginrequirements. Changes in market conditions or unforeseen extreme market events could result in our customers experiencing losses in excess of the fundsthey have deposited with us. In such an event, we may not be able to recover the negative client equity from our customers, which may result in our incurringa bad debt expense. In addition, if we cannot recover funds from our customers, we may nonetheless be required to fund28 Table of Contentspositions we hold with our liquidity providers or other third parties. Any of the foregoing events could have a material adverse effect on our business,financial condition, results of operations and cash flows.Failure of third-party systems or third-party service and software providers upon which we rely could adversely affect our business.We rely on certain third-party computer systems or third-party service and software providers, including trading platforms, back-office systems, Internetservice providers, software development partners and communications facilities. For example, for the year ended December 31, 2017, 37.2% of our retailtrading volume was derived from trades utilizing the MetaTrader platform, a third-party trading platform we license that is particularly popular in theinternational retail trading community. Any interruption in these third-party services, or deterioration in their performance or quality, could adversely affectour business. If our arrangement with any third party is terminated, we may not be able to find alternative systems or service providers on a timely basis or oncommercially reasonable terms. This could have a material adverse effect on our business, financial condition and results of operations and cash flows.Failure to maintain relationships with introducing brokers who direct new customers to us could have a material adverse effect on our business, financialcondition and results of operations and cash flows.We have relationships with introducing brokers who direct new customers to us and provide marketing and other services for these customers. In certainjurisdictions, we are only able to provide our services through introducing brokers. For the year ended December 31, 2017, approximately 15.7% of our retailtrading volume was derived from introducing brokers. Many of our relationships with introducing brokers are nonexclusive or may be terminated by thebrokers on short notice. In addition, under our agreements with introducing brokers, they have no obligation to provide us with new customers or minimumlevels of transaction volume. Our failure to maintain our relationships with these introducing brokers, the failure of the introducing brokers to provide us withcustomers or our failure to create new relationships with introducing brokers would result in a loss of revenue, which could have a material adverse effect onour business, financial condition and results of operations and cash flows. To the extent any of our competitors offers more attractive compensation terms toone or more of our introducing brokers, we could lose the brokers’ services or be required to increase the compensation we pay to retain the brokers. Inaddition, we may agree to set the compensation for one or more introducing brokers at a level where, based on the transaction volume generated by customersdirected to us by such brokers, it would have been more economically attractive to seek to acquire the customers directly rather than through the introducingbroker.Our business or reputation could be harmed by introducing broker misconduct or errors that are difficult to detect and deter.It may be perceived that we are responsible for any improper conduct by our introducing brokers, even though we do not control their activities. Many of ourintroducing brokers operate websites, which they use to advertise our services or direct customers to us. It is difficult for us to closely monitor the contents oftheir websites to ensure that the statements they make in relation to our services are accurate and comply with applicable rules and regulations. Anydisciplinary action taken against any of our introducing brokers in the United States and abroad could have a material adverse effect on our reputation,damage our brand name and materially adversely affect our business, financial condition and results of operations and cash flows.Risks Related to our Common StockThe market price of our common stock may be volatile.Our results of operations and cash flows have fluctuated significantly from period to period in the past based on a variety of factors, including some that arebeyond our control, such as currency volatility and fluctuations in trading volume. These variations, along with any failure to achieve operating results thatmeet or exceed the expectations of our investors and the market as a whole, could result in significant price and volume fluctuations in our common stock.Other factors that could affect the market price of our common stock include:•future announcements concerning us or our competitors, including the announcement of acquisitions;•changes in government regulations or in the status of our regulatory approvals or licensure;•public perceptions of risks associated with our services or operations;•developments in our industry; and•general economic, market and political conditions and other factors that may be unrelated to our operating performance or the operatingperformance of our competitors.29 Table of ContentsIf securities analysts stop publishing research or reports about us or our business or if they downgrade our common stock, the market price of our commonstock could decline.The market for our common stock relies in part on the research and reports that industry or financial analysts publish about us or our business. We do notcontrol these analysts. If any analyst who covers us downgrades our stock or lowers its future stock price targets or estimates of our operating results, ourstock price could decline rapidly. Furthermore, if any analyst ceases to cover us, we could lose visibility in the market, which in turn could cause the marketprice of our common stock to decline.Our stockholder rights plan may prevent efforts by our stockholders to effect a change of control of our company or a change in our management.We have adopted a stockholder rights plan, commonly referred to as a poison pill. The rights plan is intended to deter an attempt to acquire us in a manner oron terms not approved by our Board of Directors. The rights plan will not prevent an acquisition that is approved by our Board of Directors. Our rights plancould substantially impede the ability of public stockholders to benefit from a change in control and, as a result, may reduce the market price of our commonstock and the ability of holders of our common stock to realize any potential change of control premium.We may be unable to obtain capital when we need it, on acceptable terms, or at all.Our business depends on the availability of adequate funding and regulatory capital under applicable regulatory requirements. Historically, we have satisfiedthese needs from internally generated funds and from our offering of convertible debt securities. While we currently anticipate that our available cashresources will be sufficient to meet our presently anticipated working capital and capital expenditure requirements for at least the next 12 months, we mayneed to raise additional funds to:•support more rapid expansion;•develop new or enhanced services and products;•respond to competitive pressures;•acquire new businesses, products or technologies; or•respond to unanticipated requirements.Additional financing may not be available when needed on terms favorable to us or at all.The limited liquidity for our common stock could affect your ability to sell your shares at a satisfactory price.Our common stock is relatively illiquid. As of March 1, 2018, we had 44,864,805 shares of common stock outstanding (excluding shares held by us astreasury stock). The average daily trading volume in our common stock during the 60 calendar days ended March 1, 2018 was approximately 1,833,780shares. A more active public market for our common stock may not develop, which could continue to adversely affect the liquidity of our common stock andadversely affect the trading price of our common stock. Moreover, without a large public float, our common stock is less liquid than the stock of companieswith broader public ownership and, as a result, the trading prices of our common stock may be more volatile than that of other companies or the market as awhole. In addition, in the absence of an active public trading market, you may be unable to liquidate your investment in us at a satisfactory price.Stockholders may be diluted by the future issuance of additional common stock in connection with our incentive plans, acquisitions, conversion of our4.125% Convertible Senior Notes due 2018 or our 4.125% Convertible Senior Notes due 2020 or our 5.00% Convertible Senior Notes due 2022, orotherwise.As of December 31, 2017, we had approximately 66.4 million shares of common stock authorized but unissued. As of December 31, 2017, we have reservedan aggregate of 4.0 million shares for issuance under our equity incentive compensation plans.In addition, our 4.125% Convertible Senior Notes due 2018, which were issued in November 2013, are convertible into shares of our common stock,although we may, at our election and subject to certain limitations, choose to settle any conversion by the payment or delivery of cash, shares of our commonstock, or a combination thereof. Prior to June 1, 2018, these notes may be converted only upon the occurrence of specified events set forth in the indenturepursuant to which they were issued, while on or after June 1, 2018, holders may convert their notes at any time. During 2016 and 2017 the Companyrepurchased a significant portion of these Convertible Senior Notes and, as of December 31, 2017, the outstanding principal amount of the notes outstandingwas $6.4 million.30 Table of ContentsOur 4.125% Convertible Senior Notes due 2020, which were issued in April 2015 in connection with our acquisition of City Index, are convertible intoshares of our common stock, although we may, at our election and subject to certain limitations, choose to settle any conversion by the payment or deliveryof cash, shares of our common stock, or a combination thereof. Prior to October 1, 2019, these notes may be converted only upon the occurrence of specifiedevents set forth in the indenture pursuant to which they were issued, while on or after October 1, 2019, holders may convert their notes at any time.Our 5.00% Convertible Senior Notes due 2022, which were issued in August 2017, are convertible into shares of our common stock, although we may, at ourelection and subject to certain limitations, choose to settle any conversion by the payment or delivery of cash, shares of our common stock, or a combinationthereof. Prior to April 15, 2022, these notes may be converted only upon the occurrence of specified events set forth in indenture pursuant to which they wereissued, while on or after April 15, 2022, holders may convert their notes at any time.Any common stock that we issue, including under our 2015 Plan, 2011 Employee Stock Purchase Plan or other equity incentive plans that we may adopt inthe future, or upon conversion of any of our convertible senior notes, will dilute the percentage ownership held by investors who own our common stock.ITEM 1B.

MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITYSECURITIESOur common stock began trading on the New York Stock Exchange under the symbol “GCAP” on December 15, 2010. Prior to that date, there was noestablished trading market for our common stock. As of March 1, 2018, we estimate that we had approximately 72 stockholders of record. Because many ofour shares of common stock are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of underlyingbeneficial stockholders represented by these record holders.The following table details the high and low closing prices for the common stock as reported by the New York Stock Exchange for the periods indicated.2017 2016QuarterHigh Low High LowFirst Quarter$8.40 $6.62 $7.61 $6.21Second Quarter$8.68 $5.63 $7.03 $6.11Third Quarter$7.21 $6.16 $6.97 $6.15Fourth Quarter$10.00 $6.14 $7.01 $4.57DIVIDEND POLICYIn October 2011, our Board of Directors approved a policy of paying quarterly dividends, subject to available cash flow from operations, other considerationsand the determination by our Board of Directors of the amount. Each quarter since, we have paid a $0.05 per share dividend to holders of our common stock.In November 2016, our Board of Directors approved a change in the dividend policy which increased the dividend to $0.06 per share to holders of ourcommon stock. The latest dividend of $0.06 per share was declared on March 6, 2018 and is payable on March 30, 2018 to stockholders of record onMarch 27, 2018.Although we intend to continue our policy of paying quarterly dividends, any declaration and payment of dividends will be at the discretion of our Board ofDirectors and will depend upon, among other things, our earnings, financial condition, capital requirements, level of indebtedness, contractual restrictionswith respect to the payment of dividends, and other considerations that our Board of Directors deems relevant. The Board’s ability to declare a dividend isalso subject to limits imposed by Delaware corporate law. In addition, our subsidiaries are permitted to pay dividends to us subject to (i) certain regulatoryrestrictions related to the maintenance of minimum net capital in those of our subsidiaries that are subject to net capital requirements imposed by applicablelaw or regulation and (ii) general restrictions imposed on dividend payments under the laws of the jurisdiction of incorporation or organization of eachsubsidiary.RECENT SALES OF UNREGISTERED SECURITIES; USE OF PROCEEDS FROM REGISTERED SECURITIESNone.REPURCHASES OF COMMON STOCKDuring the year ended December 31, 2017, we repurchased approximately 3.8 million shares of our common stock pursuant to the terms of our approvedstock repurchase plan.32 Table of Contents Total Maximum Number Number of Shares (or Approximate Purchased as Dollar Value) of Part of Publicly Shares that May Total Number Announced Yet Be Purchased of Shares Average Price Plans or Under the Plans orPeriodPurchased(1) Paid per Share(1) Programs(1) Programs(1)(2)(3)January 2017283,436 $7.06 283,436 $22,539,824February 2017188,013 $7.98 188,013 $21,036,448March 2017140,974 $8.15 140,974 $19,884,029April 2017125,186 $7.58 125,186 $18,932,263May 2017263,238 $6.08 263,238 $17,327,119June 2017372,838 $5.90 372,838 $15,119,768July 2017190,823 $6.47 190,823 $13,880,398August 20172,211,775 $6.83 88,789 $13,267,186September 2017— $— — $13,267,186October 2017— $— — $13,267,186November 2017— $— — $13,267,186December 2017— $— — $13,267,186(1) On May 16, 2011, the Company announced that its Board of Directors approved a share repurchase plan, which authorized the expenditure of up to $10.0million for the purchase of the Company’s common stock.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSThe following discussion and analysis should be read in conjunction with our audited consolidated financial statements and the accompanying notes theretoprovided under “Item 8. Financial Statements and Supplementary Data” contained elsewhere within this Annual Report on Form 10-K.OverviewWe are a global provider of trading services and solutions, specializing in over-the-counter, or OTC, and exchange-traded markets. We offer our customersaccess to a diverse range of over 12,500 financial products, including spot foreign exchange, or forex, and precious metals trading, as well as “contracts fordifference”, or CFDs, which are investment products with returns linked to the performance of underlying assets.We operate our business in three segments. Through our retail segment, we provide our retail customers around the world with access to a diverse range ofglobal financial markets, including spot forex, precious metals, spread bets and CFDs on commodities, indices, individual equities and interest rate products,as well OTC options on forex. Our institutional segment provides agency execution services and offers access to markets and self-directed trading in foreignexchange, commodities, equities, options and futures via our GTX platform. Our futures segment offers execution and risk management services forexchange-traded futures and futures options on major U.S. and European futures and options exchanges. Each of our operating segments is discussed in moredetail below.As a global provider of online trading services, our results of operations are impacted by a number of external market factors, including market volatility andtransaction volumes, competition, the regulatory environment in the various jurisdictions and markets in which we operate and the financial condition of theretail and institutional customers to whom we provide our services. These factors are not the only factors that impacted our results of operations for the mostrecent fiscal period, and additional or other factors may impact, or have different degrees of impact, on our results of operations in future periods. Please see“Item 1A. Risk Factors” for a discussion of other factors that may impact our business.Market Environment and Trading VolatilityOur revenue and operating results may vary significantly from period to period primarily due to movements and trends in the world’s financial markets and tofluctuations in market volatility. Market volatility is driven by a range of external factors, some of which are market specific and some of which are correlatedto general macroeconomic conditions. As a general rule, our businesses typically benefit from volatility in the prices of the products that we offer, as periodsof increased volatility often coincide with higher levels of trading by our clients and a higher volume of transactions. However, periods of extreme volatilitymay result in significant market dislocations that can also lead clients to reduce their trading activity. In addition, volatility that results in market pricesmoving within a relatively narrow band of prices may lead to less profitable trading activity. Also, low or extremely high market volatility can adverselyaffect our ability to profitably manage our net exposure, which represents the unhedged portion of the trading positions we enter into with customers in ourretail segment.Our financial performance throughout 2017 reflects the effects of the lowest market volatility levels experienced over the past decade; with the trend one ofgenerally decreasing volatility throughout the year and the lowest levels occurring in the fourth quarter of 2017. Despite the macro pressure on our business,we saw pockets of growth, particularly in direct client assets and our ECN platform, which has been taking market share and increasing trading volume.CompetitionThe products we offer have generally been accessible to retail investors for a significantly shorter period than many other securities products, such as cashequities, and our industry is rapidly evolving and characterized by intense competition. Entering new markets often requires us to lower our pricing in orderto attract customers and compete with other companies which have already established customer bases in such markets. In addition, in existing markets, onoccasion we make short-term decisions to be more aggressive regarding the pricing we offer our customers, or we may decide to offer additional services atreduced rates, or free of charge, in order to attract customers and take market share from our competitors.Regulatory EnvironmentThe major global regulatory overhaul of financial markets which occurred following the financial crisis in 2008 has generally continued in the variousjurisdictions in which we operate. Early examples of such overhaul in the United States included passage of he Dodd-Frank Act and various relatedamendments to the Commodity Exchange Act. In December 2016, the FCA issued a consultation paper, referred to as CP16/40, that included a number ofproposed changes to the regulatory requirements36 Table of Contentsrelating to companies, such as GCUK2, that offer CFDs and spread bets. These proposed requirements included enhanced risk disclosures, a ban on offeringaccount bonuses or similar promotional incentives to clients, mandatory margin close-out levels for retail clients and limitations on the leverage that may beoffered to clients, with the limitations varying based on whether the clients are classified as experienced or inexperienced using criteria identified by theFCA. In June 2017, the FCA stated that any further action would be delayed pending action by the European Securities and Markets Authority, which hasbeen reviewing the regulation of CFDs by various European regulators for several years.In January 2018, ESMA issued a consultation paper, referred to as ESMA35-43-904. In this paper, ESMA has stated that it is considering the possible use ofits new product intervention powers under Article 40 of MiFIR to address investor protection concerning the marketing, distribution and sale of CFDs andbinary options to retail investors. These proposals are similar to those issued by the FCA and include the use of enhanced risk disclosures, restrictions uponthe offering of promotional incentives to clients, mandatory margin close-out levels for retail clients and varying limitations on the opening leverage thatmay be offered to clients; including an overall cap of 30 to 1 leverage for major foreign currency pairs and lower leverage levels for other asset classes. TheFCA has indicated that any U.K. policy measures would take in to account such ESMA measures once finalized. The comment period for ESMA’sconsultation expired in February 2018 and we cannot currently predict which, if any, of the proposed changes will be implemented. If ESMA's proposals areenacted as proposed, or similar measures are adopted, they will apply across Europe, including to our U.K. operations. The restrictions on leverage areexpected to have a material effect on our clients' trading patterns and could have a material adverse effect on or results of operations and financial condition.Similarly, the Japanese Financial Services Authority has proposed lowering permitted leverage for foreign currency and CFD's offered to retail investors inJapan to a maximum of 10 to 1. If adopted, our Japanese clients trading pattern may change significantly and the results of operations from our Japanesebusiness may be materially adversely affected. As a result of regulatory change, we may be required to change our business strategy, including the nature ofthe products that we offer, the target market for our products or our overall strategy toward one or more geographic markets.Part of our growth strategy is to enter new markets, and as we do so we will become subject to regulation in those markets. Complying with differentregulatory regimes in multiple markets is expensive, and in many markets the regulatory environment is unclear and evolving.FXCM Asset AcquisitionOn February 7, 2017, we entered into an Asset Purchase Agreement (the “Purchase Agreement”) with Forex Capital Markets L.L.C. (“FXCM"). Pursuant to theterms of the Purchase Agreement, FXCM transferred substantially all of its U.S.-domiciled customer accounts to us effective as of February 24, 2017. Inconsideration of the transfer of these accounts, we agreed to pay FXCM, without duplication:•$500 per account for each transferred account that first executes a new trade with GAIN during the 76-day period immediately following the closingof the account transfer (the “Initial Period”); and•$250 per account for each transferred account that (i) did not execute a new trade with GAIN during the Initial Period and (ii) executes a new tradewith GAIN during the 77-day period immediately following the last day of the Initial Period.We paid $7.2 million to FXCM as consideration for the purchased accounts for the twelve months ended December 31, 2017, which was capitalized andincluded as an intangible asset to be amortized on a straight line basis over its two year useful life.Credit FacilityOn August 3, 2017, we entered into a Credit Agreement (the “Credit Agreement”), with Barclays Bank PLC (“Barclays”), as Administrative Agent, CollateralAgent, Arranger and Documentation Agent, Sterling National Bank as Joint Bookrunner (“Sterling”), and the other lenders from time to time party thereto(together with Barclays and Sterling, the “Lenders”).The Credit Agreement provides for a U.S. $50.0 million senior secured first lien revolving credit facility (the “Facility”), to be made available upon certainterms and conditions described below. Upon our request, the Facility may be increased by up to $25.0 million, with a minimum increase of $5.0 million. EachLender has the absolute discretion to provide all or any part of the requested increase, or to decline to participate in the increase. Amounts available under theFacility may be borrowed, repaid and reborrowed on and after the closing date until the third anniversary of the closing date (the “Maturity Date”). Allamounts outstanding under the Facility will initially bear interest, at our option, at a rate per annum equal to (i) the “Cost of37 Table of ContentsFunds Rate” or, if applicable, “Base Rate” plus 1.75% per annum, or (ii) “LIBOR Rate” plus 2.75% per annum, in each case as such terms are defined in theCredit Agreement. Beginning on the date on which we deliver to the Lenders financial statements for the first full fiscal quarter after the closing date, theapplicable margin for the Facility will be determined on a sliding scale based on our Consolidated Gross Leverage Ratio (as defined in the Facility). As ofDecember 31, 2017 the interest rate is 6.25%.All obligations under the Facility are guaranteed by each of our direct or indirect wholly-owned domestic subsidiaries (excluding our regulated subsidiaries)(collectively, the “Guarantors”). The obligations under the Facility are secured by a first priority security interest in all of the capital stock of each subsidiaryowned by us or a Guarantor (collectively, the “Collateral”), which pledge, in the case of any foreign subsidiary, is limited to 65.0% of the voting stock ofsuch foreign subsidiary and is limited to foreign subsidiaries directly owned by us or a Guarantor.The Facility contains customary financial covenants, tested quarterly, including with respect to our Consolidated Gross Leverage Ratio, ConsolidatedInterest Coverage Ratio and Minimum Net Capital, in each case as such terms are defined in the Credit Agreement. The Facility contains such representationsand warranties by us and the Guarantors as are customary for transactions and facilities of this type, subject to baskets for permitted acquisitions, dispositions,incurrence of additional indebtedness and similar transactions.In addition to other events of default that are customary for transactions and facilities of this type (subject to applicable grace periods and materialitystandards).Convertible NotesOn August 22, 2017, we issued $92.0 million aggregate principal amount of our 5.00% Convertible Senior Notes due 2022, which amount includes theexercise in full of the over-allotment option granted to the initial purchasers of the notes, in a private offering to qualified institutional buyers pursuant toRule 144A under the Securities Act of 1933, as amended. The notes bear interest at a fixed rate of 5.00% per year, payable semi-annually in arrears onFebruary 15 and August 15 of each year, beginning on February 15, 2018. The notes are convertible into cash, shares of our common stock, or a combinationthereof, at our election. The notes will mature on August 15, 2022, unless earlier converted, redeemed or repurchased. We may not redeem the notes prior toAugust 15, 2020. The net proceeds from the offering of these notes were approximately $88.4 million, after deducting discounts to the initial purchasers andoffering expenses payable by the Company.City Index AcquisitionOn April 1, 2015, we completed the acquisition of the entire issued and outstanding share capital of City Index (Holdings) Limited, or City Index, a globalonline trading firm specializing in CFDs, forex and spread betting from City Index Group Limited. The preliminary purchase price consisted ofapproximately (i) $6.1 million in cash, inclusive of working capital adjustments and $1.0 million in cash to be held in escrow; (ii) 5,319,149 shares of ourcommon stock, including 4,787,234 shares to be held in escrow; and (iii) 4.125% unsecured Convertible Senior Notes with an aggregate principal amount of$60.0 million, including convertible senior notes with an aggregate principal amount of $54.0 million to be held in escrow. In addition, we paid City Indexapproximately $22.4 million, which was used to settle certain inter-company liabilities between City Index and City Index Group Limited.Key Income Statement Line Items and Key Operating MetricsThe following section briefly describes the key components of our revenues and expenses, our use of non-GAAP financial measures, and key operatingmetrics we use to evaluate the performance of our business.RevenueRevenue from our business consists of retail revenue, institutional revenue, futures revenue, other revenue and interest revenue.Retail RevenueRetail revenue is our largest source of revenue. Retail revenue is principally comprised of trading revenue from our retail segment.Trading revenue in our retail segment is generated by forex products and non-forex products, including spot forex, precious metals, spread bets and CFDs oncommodities, indices, individual equities and interest rate products, as well as OTC options on forex.38 Table of ContentsWe generate revenue in our retail segment in two ways: (1) trading revenue from our market making activities for OTC products, earned principally from thebid/offer spread we offer our customers and fees, including financing charges for positions held overnight, commissions on equity CFD trades, and otheraccount related fees and (2) any net gains and losses generated through changes in the market value of the currencies and other products held in our netexposure.Retail revenue represented 74.9% and 80.3% of our total net revenue for the year ended December 31, 2017 and 2016, respectively.For the year ended December 31, 2017, approximately 97% of our average daily retail trading volume was either naturally hedged or hedged by us with oneof our liquidity providers, which is substantially similar to our average daily retail trading volume hedged of approximately 98% and 98% in 2016 and 2015,respectively. The remaining 3%, 2%, and 2% of our average daily retail trading volume in 2017, 2016 and 2015, respectively, consisted of our net exposure.We manage our net exposure by applying position and exposure limits established under our risk-management policies and by continuous, active monitoringby our trading and risk teams. Based on our risk management policies and procedures, over time a portion of our net exposure may be hedged with ourliquidity providers. Although we do not actively initiate proprietary market positions in anticipation of future movements in the relative prices of theproducts we offer, through our net exposure we are likely to have open positions in various products at any given time. In the event of unfavorable marketmovements, we may experience losses on such positions. Please refer to “Item 1. Business” under heading Sophisticated risk management for further detailsregarding our risk management policies for the retail segment.In 2015 and earlier periods, we had a retail sales trader business which provided high-touch trading services and execution to high net worth customers. Weprimarily earned commissions on this trade flow, which we typically hedged fully. In the latter part of 2015, our sales trader business was restructured andintegrated into the rest of the retail segment.Institutional RevenueInstitutional revenue consists of revenue from our GTX business, which provides a proprietary ECN trading platform and sales and trading services,principally to institutional customers. Revenue from our GTX business is generated primarily through commissions or commission-equivalents for tradesexecuted on the GTX platform. We act as an agent for the trades executed on the GTX platform and, therefore, do not assume any market or credit risk inconnection with those transactions. Our institutional revenue includes revenue generated by intercompany transactions with other segments/affiliates that areeliminated when calculating our consolidated net revenue. This intercompany revenue totaled approximately $0.8 million and $1.2 million for the yearended December 31, 2017 and 2016, respectively.Futures RevenueFutures revenue comprises primarily commissions earned on futures and futures options trades. We act as an agent for the trades executed in our futuressegment and are not exposed to market risk in connection with that activity.Other RevenueOther revenue primarily comprises foreign currency translation gains and losses, as well as inactivity fees. During the twelve months ended December 31,2015, corporate and other revenue also included a $6.7 million adjustment to the contingent consideration related to our Trade Facts acquisition. InDecember 2015, we entered into an agreement with the former owners of Trade Facts to satisfy all remaining obligations under the contingent earn-outarrangement for a one-time payment of $1.5 million, which was paid in early 2016.Net Interest RevenueNet interest revenue/expense consists primarily of the revenue generated by our cash and customer cash held by us at banks and on deposit as collateral withour liquidity providers, less interest paid to our customers.Our cash and customer cash is generally invested in money market funds, which primarily invest in short-term United States government securities, treasurybills, and other money market instruments. Interest paid to customers varies primarily due to the net value of a customer account. A customer’s net accountvalue equals cash on deposit plus the mark-to-market of open positions as of the measurement date. Interest income and interest expense are recorded whenearned and incurred, respectively. Net interest revenue was $4.9 million for the year ended December 31, 2017, compared to net interest revenue of $1.1million for the year ended December 31, 2016.39 Table of ContentsExpensesOur expenses are principally comprised of the following:Employee Compensation and BenefitsEmployee compensation and benefits includes salaries, bonuses, commissions, stock-based compensation, contributions to benefit programs and otherrelated employee costs.Selling and MarketingOur marketing strategy employs a combination of direct online marketing and focused branding programs, with the goal of raising awareness and cost-effectively acquiring customers for our products and services, as well as client engagement and retention.Referral FeesReferral fees consist of compensation paid to our white label partners and introducing brokers. We generally provide white label partners with the platform,systems, and back-office services necessary for them to offer trading services to their customers. Introducing brokers identify and direct customers to us.Referral fees expense also includes payments made to affiliates for referring customer to us.Referral fees are largely variable and change principally based on the level of customer trading volume directed to us from our white label partners andintroducing brokers, the specific terms of our agreements with the white label partners and introducing brokers, which vary on a partner-by-partner andregional basis, and the relative percentage of trading volume generated from particular relationships in any given period. The majority of our white label andintroducing broker partners are paid based on the trading volume generated by the customers they introduce, directly or indirectly, to us, rather than on arevenue sharing basis. As such, during periods in which their customers’ trading activity is not profitable for us, if the associated trading volume remainshigh, we may be required to make larger payments to these partners despite the fact that we are generating lower revenue from the customers that they haveintroduced. Our indirect business accounted for 33.3%, 43.5%, 48.4% of retail trading volume in the years ended December 31, 2017, 2016 and 2015,respectively. The decline in indirect volume was due to our focus on expanding our direct business, efforts to optimize our indirect channel, as well as anincrease in direct volume as a result of our acquisition of FXCM’s U.S.-domiciled customer accounts.Trading ExpensesTrading expenses consist of exchange fees paid to exchanges and other third-parties for exchange market data that we provide to our customers or use tocreate our own derived data products, as well as fees for news services and fees paid to prime brokers in connection with our institutional and futuressegments.General and AdministrativeGeneral and administrative expenses consist of bank fees, professional fees, occupancy and equipment and other miscellaneous expenses.Depreciation and AmortizationDepreciation and amortization consists of the recognition of expense for physical assets and software purchased for use over a period of several years and ofthe amortization of internally developed software.Purchased Intangible AmortizationPurchased intangible amortization consists of amortization related to intangible assets we acquired in connection with our acquisitions. The principalintangible assets acquired were technology, customer relationships and a non-compete agreement. These intangible assets have useful lives ranging from oneyear to ten years.Communications and TechnologyCommunications and technology consists of communications fees, data fees, product development, software and maintenance expenses.Bad Debt ProvisionBad debt provision represents the amounts estimated for the uncollectibility of certain outstanding balances during the period.40 Table of ContentsRestructuring ExpensesIn 2016 and 2015 we incurred restructuring expenses, which reflected costs arising from headcount reductions and other exit costs, measured and disclosed inaccordance with FASB ASC 420 Exit or Disposal Cost Obligations and ASC 712 Compensation - Nonretirement Postemployment Benefits.Acquisition ExpensesIn 2015 we incurred acquisition-related expenses, which included professional services costs, such as legal, accounting, valuation and other costs specifiedin FASB ASC 805. These costs are expensed as incurred.Integration ExpensesIn 2016 and 2015 we incurred integration expenses, which are acquisition-related costs that are incurred while integrating an acquired company into theconsolidated group. These costs include retention bonuses paid to employees and the cost of retiring redundant assets.Legal SettlementOn April 28, 2016, we entered into a settlement agreement with the claimants in the Cameron Farley Ltd. matter. Please refer to Note 16 to our auditedconsolidated financial statements for more detail. Pursuant to the terms of the settlement agreement, we agreed to make a one-time settlement payment inexchange for a full and final settlement of all claims. The settlement amount, net of insurance recoveries, totaled approximately $9.2 million.Impairment of InvestmentIn 2017 we recognized an impairment expense due to an impairment of a small equity method investment.Interest Expense on Long Term BorrowingsInterest expense on long term borrowings consists of interest expense on our 4.125% Convertible Senior Notes due 2018, issued in November 2013, interestexpense on our 4.125% Convertible Senior Notes due 2020, issued in April 2015 as part of the consideration for the City Index acquisition, and interestexpense on our 5.00% Convertible Senior Notes due 2022, issued in August 2017.Non-GAAP Financial MeasuresWe use free cash available, adjusted net income and adjusted earnings per common share, each of which is a non-GAAP financial measure, to evaluate ourbusiness. We believe our reporting of free cash available, adjusted net income and adjusted earnings per share assists investors in evaluating our operatingperformance. Free cash available, adjusted net income and adjusted earnings per common share are not measures of financial performance calculated inaccordance with GAAP. They should be considered in addition to, but not as a substitute for, other measures of our financial performance reported inaccordance with GAAP, such as net income and earnings per common share. Below is a discussion and reconciliation of these non-GAAP financial measures.Free Cash AvailableFree cash available is a non-GAAP financial measure and consists of our Cash and cash equivalents, plus our Receivables from banks and brokers, plusrevolving credit facility, less the minimum regulatory capital requirements applicable to our business. We use this non-GAAP measure to evaluate our abilityto fund growth in our business.Adjusted Net Income and Adjusted Earnings Per ShareAdjusted net income is a non-GAAP financial measure and represents our net income excluding restructuring, acquisition and integration expenses, whichinclude deal-related acquisition costs, such as legal, accounting and valuation expenses, accelerated amortization of trading platforms, loss onextinguishment of debt, loss on impairment of investments and other expenses incurred in connection with, or as a result of, merger and acquisitiontransactions. In addition, adjusted net income excludes the adjustment to the fair value of consideration from the Trade Facts acquisition and the bad debtexpense related to the Swiss National Bank event in January 2015 and costs incurred in 2017 related fees paid for the Company’s operational strategy review.We exclude these items from our adjusted net income and adjusted earnings per share, because we view these as transactions that are not part of our coreoperations, which we believe to be the most meaningful indicators of the Company’s performance.41 Table of ContentsAdjusted earnings per share is a non-GAAP financial measure and represents our adjusted net income per share. We believe these financial measures assistinvestors in evaluating our operating performance. These non-GAAP financial measures have certain limitations, including that they do not havestandardized meanings. Therefore, our definitions may be different from similar non-GAAP financial measures used by other companies or analysts, and itmay be difficult to compare our financial performance to that of other companies.Reconciliation of Non-GAAP Financial MeasuresFor a reconciliation of free cash available to Cash and cash equivalents, please refer to the “Liquidity and Capital Resources” section below. The followingtable provides a reconciliation of GAAP net income to adjusted net income and adjusted earnings per common share (amounts in thousands except per shareamounts): Year Ended December 31, 2017 2016 2015Net (loss)/income applicable to GAIN Capital Holdings, Inc.$(11,195) $35,272 $10,279 Income tax (benefit)/expense(6,855) 9,768 (3,512) Equity in net loss of affiliate343 62 — Non-controlling interest620 2,140 1,660Pre-tax (loss)/income(17,087) 47,242 8,427Adjustments: Acquisition expense— — 2,819 Restructuring— 1,041 3,482 Integration— 2,788 33,092 Other items(1)6,391 — — Adjustment to fair value of contingent consideration— — (6,722) Legal settlement— 9,205 — Bad debt related to SNB event in January 2015— — 2,500Total adjustments6,391 13,034 35,171Adjusted pre-tax (loss)/income(10,696) 60,276 43,598Normalized income tax2,246 (12,998) (7,653)Equity in net loss of affiliate(343) (62) —Non-controlling interest(620) (2,140) (1,660)Adjusted net (loss)/income (non-GAAP)$(9,413) $45,076 $34,285 Adjusted (loss)/earnings per common share (non-GAAP): Basic$(0.20) $0.93 $0.72 Diluted$(0.20) $0.92 $0.71(1) Other items include impairment of investment ($620), loss on extinguishment of debt ($4,944), and other corporate expenses ($827).42 Table of ContentsOperating MetricsIn addition to the financial measures discussed above, we review various key operating metrics, which are described below, to evaluate the performance ofour businesses.

Approximately40.1% of our overall customer trading volume in retail and institutional for the year ended December 31, 2017 was generated in our retail segment, comparedto 48.8% for the year ended December 31, 2016.OTC Average Daily VolumeAverage daily volume is the U.S. dollar equivalent of the aggregate notional value of trades executed by our customers in a given period divided by thenumber of trading days in the given period.Active OTC AccountsActive OTC accounts represents retail segment customers who executed at least one trade during the relevant period. We believe active OTC accounts is animportant operating metric because it correlates to trading volume and revenue in our retail segment.Client AssetsClient assets represent amounts due to clients in our retail and futures segments, including customer deposits and unrealized gains or losses arising from openpositions.Institutional VolumeApproximately 59.9% and 51.2% of our overall customer trading volume in retail and institutional for the years ended December 31, 2017 and 2016,respectively, was generated in our institutional segment.43 Table of ContentsECN VolumeECN volume is the U.S. dollar equivalent of the aggregate notional value of trades executed on our GTX platform.ECN Average Daily VolumeECN average daily volume is the U.S. dollar equivalent of the aggregate notional value of trades executed on our GTX platform in a given period divided bythe number of trading days in the given period.Swap Dealer VolumeSwap dealer volume is the U.S. dollar equivalent of the aggregate notional value of trades executed through our non-platform institutional trading services.Swap Dealer Average Daily VolumeSwap dealer average daily volume is the U.S. dollar equivalent of the aggregate notional value of trades executed through our non-platform institutionaltrading services in a given period divided by the number of trading days in the given period.Number of Futures ContractsNumber of futures contracts represent the total number of contracts transacted by customers in our futures segment.Futures Average Daily ContractsAverage daily futures contracts is the number of futures contracts transacted by our futures customers in a given period divided by the number of trading daysin the given period.Active Futures AccountsActive futures accounts represent customers who executed at least one futures trade during the relevant period.We believe that our customer trading volumes are driven by eight main factors. Four of these factors are broad external factors outside of our control thatgenerally impact customer trading volumes, and include:•overall economic conditions and outlook;•volatility of financial markets;•legislative changes; and•regulatory changes.The volatility of financial markets has generally been positively correlated with customer trading volume. Our customer trading volume is also affected bythe following four additional factors:•the effectiveness of our sales activities;•the competitiveness of our products and services;•the effectiveness of our customer service team; and•the effectiveness of our marketing activities.In order to increase customer trading volume, we focus our marketing and our customer service and education activities on attracting new customers andextending the duration and scope of the relationship our customers have with us.Results of OperationsOur segment reporting structure includes three operating segments (retail, institutional, and futures). These operating segments are discussed in more detailbelow. We also report information relating to general corporate services in a fourth component, corporate and other.

historically financed our liquidity and capital needs primarily through the use of funds generated from operations by our subsidiaries, the issuanceof debt and equity securities, including the 4.125% Convertible Senior Notes due 2018 that we issued in the fourth quarter of 2013, the 4.125% ConvertibleSenior Notes due 2020 that were issued in 2015 in connection with our acquisition of City Index, the 5.00% Convertible Senior Notes due 2022 that wereissued in the third quarter of 2017, and access to secured lines of credit, such as the revolving credit facility entered into in August 2017. We plan to financeour future operating liquidity and regulatory capital needs in a manner consistent with our past practice. We expect that our capital expenditures for the next12 months will be lower than 2017, as we continue to identify areas for savings.We primarily hold and invest our cash at various financial institutions and in various investments, including cash held at banks, deposits at our liquidityproviders and money market funds which primarily invest in short-term U.S. government securities, treasury bills, and other money market instruments. Ingeneral, we believe all of our investments and deposits are of high credit quality and we have more than adequate liquidity to conduct our businesses.Several of our operating subsidiaries are subject to requirements of regulatory bodies, including the CFTC and NFA in the United States, the FCA in theUnited Kingdom, the FSA, METI and MAFF in Japan, the SFC in Hong Kong, IIROC and the OSC in Canada, MAS in Singapore, ASIC in Australia, and theCIMA in the Cayman Islands, which limit funds available for the payment of dividends to GAIN Capital Holdings, Inc.

A number of significant provisionscontained in the law affect, or will affect once implementing regulations are adopted by the appropriate federal agencies, our business. Among other things,the Dodd-Frank Act provides for additional regulation of swaps and security-based swaps, including some types of foreign exchange and metals derivativesin which we engage. The Dodd-Frank Act requires the registration of swap dealers with the CFTC and imposes significant regulatory requirements on swapdealers and swap execution facilities. Effective February 27, 2013, GAIN GTX, LLC became provisionally registered with the CFTC and NFA as a swapdealer. Effective June 2016, GTX SEF, LLC became permanently registered with the CFTC as a swap execution facility, replacing the temporary registrationpreviously granted in April 2014. Certain of our other subsidiaries may be required to register, or may register voluntarily, as swap dealers and/or swapexecution facilities.Swap dealers and swap execution facilities are subject to a comprehensive regulatory regime with new obligations for the swaps activities for which they areregistered, including adherence to risk management policies, supervisory procedures, trade record and real time reporting requirements, as well as proposedrules for new minimum capital requirements. GAIN GTX, LLC and GTX SEF, LLC have faced, and may continue to face, increased costs due to theregistration and regulatory requirements listed above, as may any other of our subsidiaries that register as a swap dealer and/or swap execution facility. Inparticular, the CFTC has proposed rules that would require a swap dealer to maintain regulatory capital of at least $20 million. Compliance with this or otherswap-related regulatory capital requirements may require us to devote more capital to our GTX business or otherwise restructure our operations, such as bycombining our GTX business with other regulated subsidiaries that must also satisfy regulatory capital requirements. The increased costs associated withcompliance, and the changes that will be required in our OTC and clearing businesses, may adversely impact our results of operations, cash flows or financialcondition.Operating CashWe are required to maintain cash on deposit with our liquidity providers in order to conduct our hedging activities.

The net proceeds from the note offering wereapproximately $77.2 million, after deducting discounts to the initial purchasers and estimated offering expenses payable by the Company. We used a portionof the net proceeds of the offering of our 5.00% Convertible Senior Notes due 2022 to repurchase $71.8 million in principal amount of our 4.125%Convertible Senior Notes due 2018.The notes bear interest at a fixed rate of 4.125% per year, payable semi-annually in arrears on June 1 and December 1 of each year, beginning on June 1,2014. The notes are convertible into cash, shares of our common stock, or a combination thereof, at our election. The notes will mature on December 1, 2018,unless earlier converted, redeemed or repurchased.On April 1, 2015, as part of the consideration for our acquisition of City Index, we issued $60.0 million aggregate principal amount of our 4.125%Convertible Senior Notes due 2020 to City Index Group Limited. These notes bear interest at a fixed rate of 4.125% per year, payable semi-annually in arrearson April 1 and October 1 of each year, beginning on October 1, 2015. The notes are convertible into cash, shares of our common stock, or a combinationthereof, at our election, subject to certain limitations. The notes will mature on April 1, 2020, unless earlier converted, redeemed or repurchased. We may notredeem the notes until the two year period prior to the maturity date of the notes.On August 22, 2017, we issued $92.0 million aggregate principal amount of our 5.00% Convertible Senior Notes due 2022, which includes the exercise infull of the over-allotment option granted to the initial purchasers of the notes, in a private offering to qualified institutional buyers pursuant to Rule 144Aunder the Securities Act of 1933, as amended. The notes bear interest at a fixed rate of 5.00% per year, payable semi-annually in arrears on February 15 andAugust 15 of each year, beginning on February 15, 2018. The notes are convertible into cash, shares of our common stock, or a combination thereof, at ourelection. The notes will mature on August 15, 2022, unless earlier converted, redeemed or repurchased. We may not redeem the notes prior to August 15,2020. The net proceeds from the offering of these notes were approximately $88.4 million, after deducting discounts to the initial purchasers and estimatedoffering expenses payable by the Company.Under applicable accounting guidance, an entity must separately account for the liability and equity components of convertible debt instruments whoseconversion may be settled entirely or partially in cash in a manner that reflects the issuer’s economic interest cost for non-convertible debt. The liabilitycomponent of the notes is initially valued at the fair value of a similar debt instrument that does not have an associated equity component and is reflected asa liability in our consolidated balance sheet in an amount equal to the fair value, which, as of December 31, 2017 and 2016, was $132.2 million and $124.8million, respectively. The equity component of the notes is included in the additional paid-in capital section of our shareholders’ equity on our ConsolidatedBalance Sheets, and the value of the equity component is treated as original issue discount for purposes of accounting for the debt component. The equitycomponent, as of December 31, 2017 and 2016, for our convertible senior notes was $38.6 million and $27.4 million, respectively. This original issuediscount is amortized to non-cash interest expense over the term of the notes, and, as a result, we record a greater amount of interest expense in currentperiods. Accordingly, we reported lower net income in our financial results than would have been recorded had we reflected only cash interest expense in ourconsolidated income statement because ASC 470-20 requires the interest expense associated with the notes to include both the current period’s amortizationof the original issue discount and the notes’ cash coupon interest, which could adversely affect our reported or future financial results, the trading price of ourcommon stock and the trading price of the notes.In addition, under certain circumstances, convertible debt instruments whose conversion may be settled entirely or partly in cash (such as our 4.125%Convertible Senior Notes due 2018, 4.125% Convertible Senior Notes due 2020, and 5.00% Convertible Senior Notes due 2022) are currently accounted forusing the treasury stock method. Under this method, the shares issuable upon conversion of the notes are not included in the calculation of diluted earningsper share unless the conversion value of the notes exceeds their principal amount at the end of the relevant reporting period. If the conversion value exceedstheir principal amount, then, for diluted earnings per share purposes, the notes are accounted for as if the number of shares of common stock that would benecessary to settle the excess, if we elected to settle the excess in shares, were issued. The accounting standards in the future may not continue to permit theuse of the treasury stock method. If we are unable to use the treasury stock method in accounting for the shares, if any, issuable upon conversion of the notes,then our diluted earnings (loss) per share could be adversely affected.58 Table of ContentsCredit FacilityOn August 3, 2017, the Company entered into a Credit Agreement, dated as of August 2, 2017, for a three year U.S. $50.0 million senior secured first lienrevolving credit facility that matures in August 2020.

Referral fees consist primarily of payments made to our white label partners andintroducing brokers.Unrealized gains and losses on cash positions revalued at prevailing foreign currency exchange rates are included in trading revenue but have no directimpact on cash flow from operations. Gains and losses become realized and impact cash flow from operations when customer transactions are liquidated.

The preparationof these financial statements requires us to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure ofcontingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the periods presented. Weevaluate these estimates and assumptions on an ongoing basis. We base our estimates on the information currently available to us and on various otherassumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions orconditions.An accounting policy is deemed to be critical if it requires management’s most difficult, subjective, or complex judgments, often as a result of the need tomake estimates about the effects of matters that are inherently uncertain. While our significant accounting policies are described in more detail in the notes toour consolidated financial statements, we believe the following accounting policies are critical to the estimates and assumptions used in the preparation ofour consolidated financial statements.Goodwill and Intangible AssetsWe obtained goodwill and intangible assets as a result of the acquisitions of certain of our subsidiaries. Goodwill represents the excess of the cost over thefair market value of net assets acquired. We are required to periodically assess whether any of our goodwill is impaired. In order to do this, we apply judgmentin determining our reporting units, which represent our business segments. In accordance with relevant accounting guidance, we test goodwill for impairmenton an annual basis during the fourth quarter and on an interim basis when conditions indicate impairment may have occurred. When testing for goodwillimpairment, the Company first assesses qualitative factors to determine whether the existence of events or circumstances leads to a determination that it ismore likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company concludes it is more likely than not that the fairvalue of a reporting unit is less than its carrying amount, a quantitative fair value test is performed to determine any potential impairment loss. We performedour annual test for goodwill impairment in the fourth quarter of 2017 and noted there was no impairment. Intangible assets with definite useful lives are subject to amortization and are evaluated for recoverability when events or changes in circumstances indicatethat an intangible asset’s carrying amount may not be recoverable in accordance with ASC 360, Property, Plant, and Equipment. If such an event or changeoccurs, we estimate cash flows directly associated with the use of the intangible asset to test its recoverability and assess its remaining useful life. Theprojected cash flows require assumptions related to revenue growth, operating margins and other relevant market, economic and regulatory factors. If theexpected undiscounted future cash flows from the use and eventual disposition of a finite‑lived intangible asset or asset group are not sufficient to recover thecarrying value of the asset, we then compare the carrying amount to its current fair value. We estimate the fair value using market prices for similar assets, ifavailable, or by using a discounted cash flow model. We then recognize an impairment loss for the amount by which the carrying amount exceeds its fairvalue. While we believe our assumptions are reasonable, changes in these assumptions may have a material impact on our financial results.Income TaxesASC 740, Income Taxes, establishes financial accounting and reporting standards for the effect of income taxes. The objectives of accounting for incometaxes are to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences ofevents that have been recognized in an entity’s financial statements or tax returns. A valuation allowance may be recorded against deferred tax assets if it ismore likely than not that those assets will not be realized. Judgment is required in assessing the future tax consequences of events that have been recognizedin our financial statements or tax returns. Fluctuations in the actual outcome of these future tax consequences could materially impact our financial positionor results of operations. We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by thetaxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measuredbased on the largest benefit for each such position that has a greater than fifty percent likelihood of being realized upon ultimate resolution. We considermany factors when evaluating and estimating our tax positions and tax benefits. Such estimates involve interpretations of regulations, rulings, case law, etc.and are inherently complex. Our estimates may require periodic adjustments and may not accurately anticipate actual outcomes as61 Table of Contentsresolution of income tax treatments in individual jurisdictions typically would not be known for several years after completion of any fiscal year. The impactof our reassessment of uncertain tax positions in accordance with ASC 740 did not have a material impact on the results of operations, financial condition orliquidity.Recent Accounting PronouncementsIn May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers”, which is part of ASC Topic 606. It defines how companiesreport revenues from contracts with customers and also requires certain enhanced disclosures. The standard’s provisions and related amendments are effectivefor annual reporting periods beginning after December 15, 2017. On January 1, 2018, the Company adopted this guidance, which did not have a materialimpact on the Company’s financial statements. A substantial portion of revenue falls under ASC Topic 825, Financial Instruments, which is excluded fromthe scope of the new guidance. The Company adopted ASU No. 2014-09 using the modified retrospective approach, which includes presenting thecumulative effects of initial application, if any, along with supplemental disclosures.In November 2016, the FASB issued ASU No. 2016-18, “Restricted Cash”, requiring that amounts generally described as restricted cash and restricted cashequivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statementof cash flows. The new guidance became effective on January 1, 2018 and will be applied using a retrospective transition method to each period presented.The Company concluded that cash held for customers, including amounts required to be segregated under federal or other regulations is considered restrictedcash and will present such cash with total cash on the statement of cash flows.In January 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” whicheliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (Step 2) from the goodwill impairmenttest. Instead, an impairment charge will equal the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the amount ofgoodwill allocated to the reporting unit. The guidance will be effective prospectively for the Company for the quarter ending December 31, 2020, with earlyadoption permitted after January 1, 2017. Management will adopt this approach to the extent if Step 2 is required.In February 2016, the FASB issued ASU No. 2016-02, which amended the guidance on accounting for leases. The FASB issued this update to increasetransparency and comparability among organizations. This update requires recognizing lease assets and lease liabilities on the balance sheet and disclosingkey information about leasing arrangements. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods withinthat fiscal year. The Company is currently assessing the impact on its Financial Statements of adopting this guidance.In February 2018, the FASB issued ASU No. 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220),” to address certain income taxeffects in Accumulated Other Comprehensive Income (AOCI) resulting from the tax reform enacted in 2017. The amended guidance provides an option toreclassify tax effects within AOCI to retained earnings in the period in which the effect of the tax reform is recorded. The amendments are effective for fiscalyears beginning after December 15, 2018, including interim periods. Early adoption is permitted. The Company is currently assessing the impact on itsFinancial Statements of adopting this guidance.ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKMarket risk refers to the potential for adverse changes in the value of a Company’s financial instruments as a result of changes in market conditions. We donot hold financial instruments for trading purposes on a long-term basis. We continually evaluate our exposure to market risk and oversee the establishmentof policies, procedures and controls to ensure that market risks are identified and analyzed on an ongoing basis.Interest Rate RiskInterest rate risk arises from the possibility that changes in interest rates will impact our consolidated financial statements. Our net interest revenue is directlyaffected by the short-term interest rates we earn from re-investing our cash and our customer’s cash. As a result, a portion of our interest income will decline ifinterest rates fall. Short-term interest rates are highly sensitive to factors that are beyond our control, including general economic conditions and the policiesof various governmental and regulatory authorities. Our cash and cash equivalents and customer cash and cash equivalents are held in cash and cashequivalents including cash at banks, deposits at liquidity providers, in money market funds that invest in short-term U.S. government securities and in UnitedStates and Canadian Imperial Bank of Commerce treasury bills. The interest rates earned on these deposits and investments affects our interest revenue. Weestimate that as of December 31, 2017, an immediate 100 basis point increase in short-term interest rates would result in approximately $10.3 million more inannual pretax income.62 Table of ContentsForeign Currency RiskCurrency risk arises from the possibility that fluctuations in foreign exchange rates will impact the value of our earnings and assets. Entities that have assetsand liabilities denominated in currencies other than the primary economic environment in which the entity operates are subject to re-translation. We monitorour exchange rate exposure and may make settlements to reduce our exposure. We do not take proprietary directional market positions.Virtually all sales and related operating costs are denominated in the currency of the local country and translated into USD for consolidated reportingpurposes. Although the majority of the assets and liabilities of these subsidiaries are denominated in the functional currency of the subsidiary, they may alsohold assets or liabilities denominated in other currencies. These items may give rise to foreign currency transaction gains and losses. As a result, our results ofoperations and financial position are exposed to changing currency exchange rates. We may consider entering into hedging transactions to mitigate ourexposure to foreign currency exchange rates. These hedging transactions may not be successful.Credit RiskOur trading operations require a commitment of our capital and involve risk of loss because of the potential that a customer’s losses may exceed the amountof cash in their account. While we are able to closely monitor each customer’s exposure, it does not guarantee our ability to eliminate negative customeraccount balances prior to an adverse currency price change or other market events, such as the extreme volatility in the Swiss franc following the SNB marketevent in January 2015. Changes in market conditions or unforeseen extreme market events could result in our customers experiencing losses in excess of thefunds they have deposited with us. In such an event, we may not be able to recover the negative client equity from our customers, which could materiallyadversely affect our results of operations. In addition, if we cannot recover funds from our customers, we may nonetheless be required to fund positions wehold with our liquidity providers or other third parties and, in such an event, our available funds may not be sufficient to meet our obligations to these thirdparties, which could materially adversely affect our business, financial condition, results of operations and cash flows.In order to help mitigate this risk, we require that each trade must be collateralized in accordance with our margin policies described below. Each customer isrequired to have minimum funds in their account for opening positions, which we refer to as the initial margin, and for maintaining positions, which we referto as maintenance margin, depending on the product being traded. Margin requirements are expressed as a percentage of the customer’s total position in thatproduct, and the customer’s total margin requirement is based on the aggregate margin requirement across all of the positions that a customer holds at anyone moment in time. Each net position in a particular product is margined separately. Accordingly, we do not net across different positions, thereby followinga more conservative margin policy. Our systems automatically monitor each customer’s margin requirements in real time, and we confirm that each of ourcustomers has sufficient cash collateral in his or her account before we execute their trades. We may also adjust required customer margins (both initial andmaintenance) from time to time based on our monitoring of various factors, including volatility and liquidity. If at any point in time a customer’s tradingposition does not comply with the applicable margin requirement, the position may be automatically liquidated, partially or entirely, in accordance with ourmargin policies and procedures. This policy protects both us and the customer. Our margin and liquidation policies are set forth in our customer agreements.We are also exposed to potential credit risk relating to the counterparties with which we hedge our trades and the financial institutions with which we depositcash. We mitigate these risks by transacting with several of the largest financial institutions in the world, with limits on our exposure to any single financialinstitution. In the event that our access to one or more financial institutions becomes limited, our ability to hedge may be impaired.63 Table of ContentsMarket RiskWe are exposed to market risk in connection with our retail trading activities. Because we act as counterparty to our retail customers’ transactions, we areexposed to risk on each trade that the market price of our position will decline. Accordingly, accurate and efficient management of our net exposure is a highpriority, and as such we have developed both automated and manual policies and procedures to manage our exposure. These risk-management policies andprocedures are established and reviewed regularly by the Risk Committee of our Board of Directors. Our risk-management policies require quantitativeanalyses by instrument, as well as assessment of a range of market inputs, including trade size, dealing rate, customer margin and market liquidity. Our risk-management procedures require our team of senior traders to monitor risk exposure on a continuous basis and update senior management both informallyover the course of the trading day and formally through intraday and end of day reporting. A key component of our approach to managing market risk is thatwe do not initiate market positions for our own account in anticipation of future movements in the relative prices of products we offer. To facilitate our risk-management activities, we maintain levels of capital in excess of those currently required under applicable regulations. As of December 31, 2017, wemaintained capital levels of $291.8 million, which represented approximately 2.6 times the capital we were required to hold under applicable regulations.Cash Liquidity RiskIn normal conditions, our market making business and related services is self-financing as we generate sufficient cash flows to pay our expenses as theybecome due. As a result, we generally do not face the risk that we will be unable to raise cash quickly enough to meet our payment obligations as they arise.Our cash flows, however, are influenced by customer trading volume, currency volatility and liquidity in markets in which we have positions. These factorsare directly impacted by domestic and international market and economic conditions that are beyond our control. In an effort to manage this risk, we havesecured a substantial liquidity pool by establishing trading relationships with several financial institutions. These relationships provide us with sufficientaccess to liquidity to allow us to consistently execute significant trades in varying market conditions at the notional amounts our customers desire byproviding us with as much as 50:1 leverage on the notional amounts of our available collateral we have on deposit with such financial institutions. Wegenerally maintain collateral on deposit, which includes our funds and our customers’ funds, with our liquidity providers. Collateral on deposit ranged from$81.4 million to $245.0 million in the aggregate during the year ended December 31, 2017.In addition, our trading operations involve the risk of losses due to the potential failure of our customers to perform their obligations under the transactionswe enter into with them, which increases our exposure to cash liquidity risk. To reduce this risk, our margin policy requires that we mark our customers’accounts to market each time the market price of a position in their portfolio changes and provides for automatic liquidation of positions, as described above.Operational RiskOur operations are subject to broad and various risks resulting from technological interruptions, failures or capacity constraints in addition to risks involvinghuman error or misconduct. Regarding technological risks, we are heavily dependent on the capacity and reliability of the computer and communicationssystems supporting our operations. Our computer infrastructure is potentially vulnerable to physical or electronic computer break-ins, viruses and similardisruptive problems and security breaches. We have established a program to monitor our computer systems, platforms and related technologies and topromptly address issues that arise. We have also established disaster recovery facilities in strategic locations to ensure that we can continue to operate withlimited interruptions in the event that our primary systems are damaged. As with our technological systems, we have established policies and proceduresdesigned to monitor and prevent both human errors, such as clerical mistakes or incorrectly placed trades, as well as human misconduct, such as unauthorizedtrading, fraud or negligence. In addition, we seek to mitigate the impact of any operational issues by maintaining insurance coverage for variouscontingencies.ITEM 8.

CONTROLS AND PROCEDURES(a) Evaluation of Disclosure Controls and Procedures64 Table of ContentsThe Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company’s reportsunder the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periodsspecified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer(“CEO”) and Chief Financial Officer (“CFO”) as appropriate, to allow timely decisions regarding required disclosure.Management of the Company, with the participation of its CEO and CFO, evaluated the effectiveness of the Company’s disclosure controls and procedures.Based on their evaluation, as of the end of the period covered by this Form 10-K, the Company’s CEO and CFO have concluded that the Company’sdisclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) were effective.(b) Management’s Report On Internal Control Over Financial ReportingManagement is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting isdefined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, our principal executiveand principal financial officers and is affected by the Company’s Board of Directors, management and other personnel, to provide reasonable assuranceregarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally acceptedaccounting principles (“GAAP”) and includes those policies and procedures that:•Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect our transactions and dispositions of our assets;•Provide reasonable assurance that transactions are recorded as necessary to permit preparation of our financial statements in accordance with GAAP,and that our receipts and expenditures are being made only in accordance with authorizations of management and directors of the Company; and•Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have amaterial effect on the financial statements.Because of its inherent limitations, a system of internal control over financial reporting can provide only reasonable assurance and may not prevent or detectmisstatements. Further, because of changes in conditions, effectiveness of internal controls over financial reporting may vary over time. Our system containsself-monitoring mechanisms, and actions are taken to correct deficiencies as they are identified. Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017. In making this assessment,management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-IntegratedFramework (2013). Based on this assessment, management, including the Company’s CEO and CFO, concluded that our internal control over financialreporting was effective as of December 31, 2017.Our independent registered public accounting firm has audited and issued a report on the effectiveness of our internal control over financial reporting as ofDecember 31, 2017 as stated in their report on the following page.(c) Changes in Internal Control Over Financial ReportingThere have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during theyear ended December 31, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.65 Table of ContentsREPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Shareholders and Board of DirectorsGAIN Capital Holdings, Inc.Opinion on Internal Control Over Financial ReportingWe have audited GAIN Capital Holdings, Inc. and subsidiaries (the Company) internal control over financial reporting as of December 31, 2017, based oncriteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteriaestablished in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidatedbalance sheets of the Company as of December 31, 2017 and 2016, the related consolidated statements of operations, comprehensive income, shareholders’equity, and cash flows for each of the years in the two-year period ended December 31, 2017, and the related notes and financial statement schedule I(collectively, the consolidated financial statements), and our report dated March 14, 2018, expressed an unqualified opinion on those consolidated financialstatements.Basis for OpinionThe Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness ofinternal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting.

Our audit of internal control over financialreporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing andevaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures aswe considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.Definition and Limitations of Internal Control Over Financial ReportingA company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reportingand the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal controlover financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairlyreflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permitpreparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are beingmade only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention ortimely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation ofeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliancewith the policies or procedures may deteriorate./s/ KPMG LLPNew York, New YorkMarch 14, 201866 Table of ContentsITEM 9B.

The prices approximate the amounts at which the Company can settle the positions at thebalance sheet date.Concentrations of Credit RiskThe Company owns financial instruments that subject the Company to credit risk. These financial instruments are held primarily in Cash and cashequivalents as well as Cash and securities held for customers. The Company’s credit risk is managed by investing cash and cash equivalents primarily inhigh-quality money market and, from time to time, U.S. Government instruments.

Identifiable significant improvements are capitalized and expenditures formaintenance and repairs are charged to expense as incurred.F-13 Table of ContentsProperty and equipment are depreciated on a straight-line basis over a three year useful life, except for leasehold improvements, which are depreciated on astraight-line basis over the shorter of the lease term or estimated useful life.The Company accounts for costs incurred to develop its trading platforms and related software in accordance with Accounting Standards Codification (ASC)350-40, Internal-Use Software. ASC 350-40 requires that such technology be capitalized in the application and infrastructure development stages. Costsrelated to training, administration and non-value-added maintenance are charged to expense as incurred. Capitalized software development costs are beingamortized over the useful life of the software, which the Company has estimated at three years.In accordance with ASC 360-10, Property, Plant and Equipment, the Company periodically evaluates the carrying value of long-lived assets when eventsand circumstances warrant such review. The carrying value of a long-lived asset is considered impaired when the anticipated identifiable undiscounted cashflows from such an asset (or asset group) are less than the carrying value. In that event, a loss is recognized in the amount by which the carrying value exceedsthe fair market value of the long-lived asset. This guidance applies to assets held for use and not to assets held for sale. The Company has no assets held forsale. The Company has identified no such impairment indicators as of December 31, 2017 or December 31, 2016.Foreign CurrenciesItems included in the financial statements of each of the Company’s subsidiaries are measured using the currency of the primary economic environment inwhich the subsidiaries operate (the functional currency). The Company has determined that it’s functional currency is U.S. dollars (USD). The Company’sAccumulated other comprehensive income/(loss) consists of foreign currency translation adjustments from subsidiaries not using the USD as their functionalcurrency.Foreign currency transactions are remeasured into functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchangegains and losses resulting from the settlement of such transactions and from the remeasurement of monetary assets and liabilities denominated in foreigncurrencies at period end exchange rates are recognized in Other revenue on the Consolidated Statements of Operations and Comprehensive Income. TheCompany recorded a foreign exchange gain of $0.7 million, and losses of $1.7 million and $2.4 million, for the years ended December 31, 2017, 2016, and2015, respectively.Intangible AssetsAccounting guidance addressing intangible assets requires purchased intangible assets other than goodwill to be amortized over their estimated useful livesunless their lives are determined to be indefinite. If indefinite-lived assets are determined to have a finite life in the future, the Company will amortize thecarrying value over the remaining estimated useful life at that time.The Company analyzes its business, legal and regulatory environment at least annually and on an interim basis when conditions indicate impairment mayhave occurred to determine whether its indefinite-lived intangible assets are likely to be impaired. This qualitative assessment indicated that it is more likelythan not that the Company’s indefinite lived intangible assets are not impaired. Please refer to Note 7 for additional information.GoodwillThe Company obtained goodwill as a result of the acquisitions of certain subsidiaries. Goodwill represents the excess of the cost over the fair market value ofnet assets acquired. In accordance with relevant accounting guidance, the Company tests goodwill for impairment on an annual basis during the fourthquarter and on an interim basis when conditions indicate impairment may have occurred (please refer to Note 7). In performing these assessments,management relies on and considers a number of factors, including operating results, business plans, economic projections, anticipated future cash flows,comparable market transactions (to the extent available), other market data and the Company’s overall market capitalization. There are inherent uncertaintiesrelated to these factors which require judgment in applying them to the analysis of goodwill and intangible assets for impairment.When testing for goodwill impairment, the Company first assesses qualitative factors to determine whether the existence of events or circumstances leads to adetermination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company concludes it is more likelythan not that the fair value of a reporting unit is less than its carrying amount, a quantitative fair value test is performed.Under the quantitative test, the fair value of each reporting unit is compared to its carrying value in order to identify potential impairment. If the fair value ofa reporting unit exceeds the carrying value of its net assets, goodwill is not considered impaired and no further testing is required. If the carrying value of thenet assets exceeds the fair value of a reporting unit, impairment is indicated at the reporting unit level and an impairment charge will be recorded. Animpairment charge will equal the amount byF-14 Table of Contentswhich a reporting unit’s carrying amount exceeds its fair value, not to exceed the amount of goodwill allocated to the reporting unit. For the year ended December 31, 2017, the Company performed a qualitative analysis for each of its reporting units to determine whether it was more likelythan not that the fair value was less than the carrying value. As a result of this assessment, the Company determined that it was not necessary to perform aquantitative impairment test and concluded that goodwill assigned to each reporting unit was not impaired at December 31, 2017.DerivativesForex, metals, and CFDs allow for exchanging the difference in value of a particular asset such as a stock index, energy product, or gold contracts, betweenthe time at which a contract is opened and the time at which it is closed. The Company’s retail customer open positions and positions held with liquidityproviders are considered derivatives under the accounting guidance in ASC 815. Derivatives and Hedging. Therefore, they are accounted for at fair value,and included in Receivables from brokers, Payables to customers, and Payables to brokers in the Consolidated Balance Sheets. The Company did notdesignate any of its derivatives as hedging instruments. Net gains and losses with respect to derivative instruments are reflected in Retail Revenue in theaccompanying Consolidated Statements of Operations and Comprehensive Income.Allowance for Doubtful AccountsThe Company records an increase in the allowance for doubtful accounts when the prospect of collecting a specific customer account balance becomesdoubtful. Management specifically analyzes accounts receivable and historical bad debt experience when evaluating the adequacy of the allowance fordoubtful accounts. Changes in estimates are recognized in current year earnings. The customer receivables, net of allowance for doubtful accounts, areincluded in Other assets on the Consolidated Balance Sheets. Receivables from customers are reserved for and the related reserves are recorded in Bad debtprovision on the Consolidated Statements of Operations and Comprehensive Income.Payables to CustomersPayables to customers, included on the Consolidated Balance Sheets, include amounts due on cash and margin transactions. These transactions includedeposits, commissions and gains or losses arising from settled trades. The payables balance also reflects unrealized gains or losses arising from open positionsin customer accounts. The Company engages in white label arrangements with other regulated financial institutions. The payables balance includes amountsdeposited by these financial institutions in order for the Company to act as a clearing broker.Payables to BrokersPayables to brokers comprise open trades, which are measured at fair value and the cash due to or from brokers, which is not measured at fair value butapproximates fair value. These balances result when the Company’s hedging trades produce a loss and necessitate a margin call to re-capitalize positions orsettle losses.Referral fees Introducing brokers direct customers to the Company in return for a commission on each referred customer’s trading volume or a share of net revenuegenerated by each referred customer’s trading activity. White label partners offer our trading services to their customers under their own brand. Their fees arereferred to as introducing broker fees and are recorded on a trade date basis, in Referral Fees, in the Consolidated Statements of Operations andComprehensive Income.Trading ExpensesTrading expenses consist of exchange fees paid to stock exchanges and other third-parties for exchange market data that the Company provides to itscustomers or uses to create its own derived data products, as well as fees for news services and clearing fees paid to prime brokers in connection with itsinstitutional GTX business and futures business. These costs are expensed as incurred.Income TaxesIncome taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequencesattributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assetsand liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to berecovered or settled. The effect onF-15 Table of Contentsdeferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance isrecorded against deferred tax assets if it is more likely than not that such assets will not be realized. Contingent income tax liabilities are recorded when thecriteria for loss recognition have been met. An uncertain tax position is recognized based on the determination of whether or not a tax position is more likelythan not to be sustained upon examination based upon the technical merits of the position. If this recognition threshold is met, the tax benefit is thenmeasured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. At December 31, 2017, theCompany has changed its position regarding the earnings of its foreign subsidiaries. As a result of changes in U.S. tax law, the Company will no longer assertpermanent reinvestment for a majority of its foreign earnings. However, the Company does assert that the earnings of its Australian subsidiaries will bepermanently reinvested in the working capital and other business needs of the subsidiaries to the extent that repatriation of these earnings would triggeradditional taxes.Share Based CompensationShare-based compensation expense requires measurement of compensation cost for share-based awards at fair value and recognition of compensation costover the vesting period, net of estimated forfeitures. For awards with service conditions, the Company recognizes compensation cost on a straight-line basisover the requisite service period.The fair value of stock options granted is estimated using the Black-Scholes option-pricing model, which considers, among other factors, the expected termof the award and the expected volatility of the Company’s stock price. Although the Black-Scholes model meets the requirements of ASC 718,Compensation-Stock Compensation, the fair values generated by the model may not be indicative of the actual fair values of the underlying awards, as it doesnot consider other factors important to those share-based compensation awards, such as continued employment, periodic vesting requirements and limitedtransferability.The risk-free interest rate used in the Black-Scholes option-pricing model is based on the U.S. Treasury yield curve in effect at the time of grant. The expectedoption life is based on historical experience of employee exercise behavior. Expected volatility is based on historical volatility, implied volatility, priceobservations taken at regular intervals and other factors deemed appropriate. Expected dividend is based upon the current dividend rate. There were no stockoptions granted in 2017.The fair value of restricted stock unit awards is based on the fair value of the Company’s common stock on the grant date.Treasury SharesIn accordance with ASC 505-30, Equity - Treasury Stock, the Company treats the cost of acquired shares purchased as a deduction from shareholders’ equityand as a reduction of the total shares outstanding when calculating earnings per share.Earnings Per Common ShareBasic earnings per common share is calculated using the weighted average common shares outstanding during the year. Common equivalent shares fromstock options and restricted stock awards, using the treasury stock method, are also included in the diluted per share calculations unless their effect ofinclusion would be anti-dilutive.

It defines how companiesreport revenues from contracts with customers and also requires certain enhanced disclosures. The standard’s provisions and related amendments are effectivefor annual reporting periods beginning after December 15, 2017. On January 1, 2018, the Company adopted this guidance, which did not have a materialimpact on the Company’s financial statements. A substantial portion of revenue falls under ASC Topic 825, Financial Instruments, which is excluded fromthe scope of the new guidance. The Company adopted ASU No. 2014-09 using the modified retrospective approach, which includes presenting thecumulative effects of initial application, if any, along with supplemental disclosures.In November 2016, the FASB issued ASU No. 2016-18, “Restricted Cash”, requiring that amounts generally described as restricted cash and restricted cashequivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statementof cash flows. The new guidance became effective on January 1, 2018 and will be applied using a retrospective transition method to each period presented.The Company concluded that cash held for customers, including amounts required to be segregated under federal or other regulations is considered restrictedcash and will present such cash with total cash on the statement of cash flows.In January 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” whicheliminates the requirement to calculate the implied fair value of goodwill to measure a goodwillF-16 Table of Contentsimpairment charge (Step 2) from the goodwill impairment test. Instead, an impairment charge will equal the amount by which a reporting unit’s carryingamount exceeds its fair value, not to exceed the amount of goodwill allocated to the reporting unit. The guidance will be effective prospectively for theCompany for the quarter ending December 31, 2020, with early adoption permitted after January 1, 2017. Management will adopt this approach to the extentStep 2 is required.In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” which amended the guidance on accounting for leases. The FASB issued thisupdate to increase transparency and comparability among organizations. This update requires recognizing lease assets and lease liabilities on the balancesheet and disclosing key information about leasing arrangements. The guidance is effective for fiscal years beginning after December 15, 2018, includinginterim periods within that fiscal year. The Company is currently assessing the impact on its Financial Statements of adopting this guidance.In February 2018, the FASB issued ASU No. 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220),” to address certain income taxeffects in Accumulated Other Comprehensive Income (AOCI) resulting from the tax reform enacted in 2017. The amended guidance provides an option toreclassify tax effects within AOCI to retained earnings in the period in which the effect of the tax reform is recorded. The amendments are effective for fiscalyears beginning after December 15, 2018, including interim periods. Early adoption is permitted. The Company is currently assessing the impact on itsFinancial Statements of adopting this guidance.3. FAIR VALUE INFORMATIONAccounting guidance defines fair value as the price that would be received in exchange for an asset or paid to transfer a liability in an orderly transactionbetween market participants at the measurement date. The guidance establishes a three level hierarchy that ranks the quality and reliability of informationused in developing fair value estimates for financial instruments. The hierarchy gives the highest priority to quoted prices in active markets and the lowestpriority to unobservable data. In cases where two or more levels of inputs are used to determine fair value, a financial instrument’s level is determined basedon the lowest level input that is considered significant to the fair value measurement in its entirety. The three levels of fair value hierarchy are summarizedbelow: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 directlyor indirectly; andLevel 3 - Valuations that require inputs that are both unobservable to a market participant and significant to the fair value measurement.For assets and liabilities that are transferred between levels during the period, fair values are ascribed as if the assets or liabilities had been transferred as of thebeginning of the period.The following table presents the Company’s assets and liabilities that were measured at fair value on a recurring basis during the reporting period and therelated hierarchy levels (amounts in thousands):F-17 Table of Contents Fair Value Measurements on a Recurring Basisas of December 31, 2017 Level 1 Level 2 Level 3 TotalFinancial Assets (Liabilities): Cash and cash equivalents: Money market accounts$219,286 $— $— $219,286Cash and securities held for customers: US treasury bills: U.S. government and agency securities105,190 — — 105,190Receivable from brokers: Broker derivative contracts— 4,966 — 4,966Other assets: Certificates of deposit175 — — 175Other130 — — 130Payables to customers: Customer derivative contracts— 129,966 $— 129,966Payables to brokers: Broker derivative contracts (3,170) (3,170)Total$324,781 $131,762 $— $456,543 Fair Value Measurements on a Recurring Basisas of December 31, 2016 Level 1 Level 2 Level 3 TotalFinancial Assets: Cash and cash equivalents: Money market accounts$120,927 $— $— $120,927Cash and securities held for customers: US treasury bills: U.S. government and agency securities135,974 — — 135,974Receivable from brokers: Broker derivative contracts— 5,228 — 5,228Other assets: Certificates of deposit175 — — 175Other115 — — 115Payables to customers: Customer derivative contracts— 115,677 — 115,677Total$257,191 $120,905 $— $378,096The Company has not changed its valuation techniques in measuring the fair value of any financial assets and liabilities during the years endedDecember 31, 2017 and December 31, 2016, nor has there been any movement between levels during these respective periods.Level 1 Financial AssetsThe Company has U.S. Treasury bills, money market accounts and certificates of deposit that are Level 1 financial instruments that are recorded based uponlisted or quoted market rates. The U.S. Treasury bills and money market accounts are recorded in Cash and cash equivalents and Cash and securities held forcustomers and the certificates of deposit are recorded in Other Assets.Level 2 Financial Assets and LiabilitiesThe Company has customer derivative contracts that are Level 2 financial instruments recorded in Payables to customers.F-18 Table of ContentsThe Company has broker derivative contracts that are Level 2 financial instruments recorded in Receivables from brokers and Payables to brokers.The fair values of these Level 2 financial instruments are based upon directly observable values for underlying instruments.Level 3 Financial LiabilitiesThe Company did not have any Level 3 Financial Assets or Liabilities on December 31, 2017 or December 31, 2016.Financial Instruments Not Measured at Fair ValueThe table below presents the carrying value, fair value and fair value hierarchy category of certain financial instruments that are not measured at fair value inthe consolidated balance sheets (amounts in thousands).Receivables from brokers comprise open trades, which are measured at fair value (disclosed above), and the Company’s posted funds with brokers that arerequired as collateral for holding trading positions, which are not measured at fair value but approximate fair value. These deposits approximate fair valuebecause they are cash balances that the Company may withdraw at its discretion. Settlement would be expected to occur within a relatively short period oftime once a withdrawal is initiated.Payables to customers comprise open trades, which are measured at fair value (disclosed above), and customer deposits that the Company holds for its role asclearing broker. These deposits are not measured at fair value, but approximate fair value, because they are cash balances that the Company or its customerscan settle at either party’s discretion. Such settlement would occur within a relatively short period of time once a withdrawal is initiated.Payables to brokers comprise open trades, which are measured at fair value (disclosed above) and the cash due to or from brokers. The cash within thisbalance is not measured at fair value but does approximate fair value, because it is immediately payable to the brokers. Settlement occurs as soon as a brokerinitiates a margin call.The carrying value of Convertible senior notes represents the notes’ principal amounts net of unamortized discount (please refer to Note 13).

These expenses reflected the cost of reducing global headcount following the City Index acquisition and are recorded in Restructuring expensesin the Consolidated Statements of Operations and Comprehensive Income. The restructuring liabilities have all been paid as of December 31, 2016. During2017, the Company incurred no additional restructuring expenses related to the global headcount reductions following the City Index acquisition.11. NON-CONTROLLING INTERESTSNon-controlling interestsIn March 2014, the Company acquired controlling interests in GAA and Top Third. The Company purchased 55% of each entity, and the respective sellersmaintained a 45% interest in each entity, subject to immediately exercisable call options for the Company to purchase the remaining interests, as well as putoptions for the sellers to sell their remaining interests in each entity to the Company that were to become exercisable in 2017. In December 2016, theCompany acquired an additional 24% of each entity and, accordingly, the respective sellers now maintain a 21% interest in each entity. In connection withthe purchase of these additional interests, the Company and the respective sellers agreed that neither would exercise the call options or put options withrespect to the remaining interests prior to December 31, 2017.In accordance with ASC 480-10-S99-3A, Classification and Measurement of Redeemable Securities, non-controlling interests are classified outside ofpermanent equity as their redemption is not (i) mandatory, (ii) at fixed prices, and (iii) exclusively within the Company’s control.F-26 Table of ContentsThe non-controlling interests are not classified as liabilities, because redemption is not mandatory or at fixed prices. They are not classified as equity becausetheir redemption is not exclusively in the Company’s control. Therefore, the non-controlling interests are held in temporary equity in the ConsolidatedBalance Sheets.The non-controlling interests’ carrying value is determined by the Company’s purchase prices and the non-controlling interests’ share of the Company’ssubsequent net income. This value is benchmarked against the redemption value of the sellers’ put options. The carrying value is adjusted to the latter,provided that it does not fall below the initial carrying values, as determined by the Company’s purchase price allocation. The Company reflects any changescaused by such an adjustment in retained earnings, rather than in current earnings.The table below reflects the non-controlling interests effects on the Company’s financial statements: Redeemable non-controllinginterestsDecember 31, 2015$11,046Purchase of additional shares of non-controlling interests(7,444)Adjustment to fair value of non-controlling interests(258)Adjustment to the redemption value of non-controlling interests2,715Net income attributable to non-controlling interests2,140Distributions to non-controlling interest holders(1,605)December 31, 2016$6,594Adjustment to the redemption value of non-controlling interests(1,656)Net income attributable to non-controlling interests620Distributions to non-controlling interest holders(1,147)December 31, 2017$4,41112.

Upon request of the Company, the credit facility may be increased by up to $25.0 million, with aminimum increase of $5.0 million. The credit facility contains covenants that are customary for an issuer with senior debt. As of December 31, 2017, we werein compliance with the covenants for our credit facility.

CONVERTIBLE SENIOR NOTESConvertible Senior Notes due 2022On August 22, 2017, the Company issued $92.0 million aggregate principal amount of its 5.00% Convertible Senior Notes due 2022, which amount includesthe exercise in full of the over-allotment option granted to the initial purchasers of the Notes, in a private offering to qualified institutional buyers pursuant toRule 144A under the Securities Act of 1933, as amended. The Notes bear interest at a fixed rate of 5.00% per year, payable semi-annually in arrears onFebruary 15 and August 15 of each year, beginning on February 15, 2018. The Notes are convertible into cash, shares of the Company’s common stock, or acombination thereof, at the Company’s election. The Company currently intends to settle the debt in cash. The Notes will mature on August 15, 2022, unlessearlier converted, redeemed or repurchased. The Company may not redeem the Notes prior to August 15, 2020. The net proceeds from the Note Offering wereapproximately $89.0 million, after deducting discounts to the initial purchasers but prior to taking into account any estimated offering expenses payable bythe Company.Prior to the close of business on the business day immediately preceding April 15, 2022, the Notes may be converted only upon the occurrence of specifiedevents set forth in the Indenture. On or after April 15, 2022, until the close of business on the business day immediately preceding the maturity date, holdersmay convert their Notes at any time. Subject to the foregoing, the Notes are convertible at the option of the holders and will be settled, at the Company’selection, by the payment or delivery of cash, shares of the Company’s common stock, or a combination thereof. The conversion rate is initially 122.0107shares ofF-27 Table of Contentsthe Company’s common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $8.20 per share of commonstock). The conversion rate and the corresponding conversion price will be subject to adjustment in some circumstances described in the Indenture. If the Company undergoes a fundamental change (as defined in the Indenture), holders may require the Company to repurchase for cash all or part of theirNotes at a purchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, thefundamental change repurchase date. In addition, in certain circumstances, the Company may be required to increase the conversion rate for any Notesconverted in connection with a make-whole fundamental change (as defined in the Indenture). The Company may not redeem the Notes prior to August 15, 2020. On and after August 15, 2020, and prior to the maturity date, the Company may redeem forcash all, but not less than all, of the Notes if the last reported sale price of its common stock equals or exceeds 130% of the applicable conversion price for atleast 20 trading days, whether or not consecutive, during the 30 consecutive trading day period ending on the trading day immediately preceding the datethe Company delivers notice of the redemption. The redemption price will equal 100% of the principal amount of the Notes to be redeemed, plus any accruedand unpaid interest to, but excluding, the redemption date. In addition, if the Company calls the Notes for redemption, a make-whole fundamental changewill be deemed to occur. As a result, the Company will, in certain circumstances, increase the conversion rate for holders who convert their Notes after theCompany delivers a notice of redemption and before the close of business on the business day immediately preceding the relevant redemption date.Convertible Senior Notes due 2020On April 1, 2015, as part of the City Index acquisition consideration, the Company issued to the sellers $60.0 million aggregate principal amount of 4.125%Convertible Senior Notes maturing on April 1, 2020.

Thereafter, until the close of business on the business day immediately preceding the maturity date, holders mayconvert their Convertible Notes at any time. The Company will settle conversions of the Convertible Notes by paying or delivering, as the case may be, cash,shares of Common Stock or a combination thereof, at its election. The conversion rate for the Convertible Notes will be equal to $1,000, divided by theinitial conversion price, rounded to the nearest 1/10,000th share of Common Stock. The initial conversion price will be equal to 125% of the arithmeticaverage of the daily volume-weighted average price for the Common Stock over the 20 consecutive trading day period ending on, and including, the tradingday immediately preceding the closing date; provided that the initial conversion price shall not exceed the greater of (i) $9.25 and (ii) the last reported saleprice of the Common Stock on the Closing Date; and shall not be less than $7.20. The conversion rate and the corresponding conversion price will be subjectto customary anti-dilution adjustments, as described in the Note Indenture, including, but not limited to, Common Stock splits, Common Stockcombinations, issuances of Common Stock as a dividend on the Common Stock, issuances of options rights, warrants or other securities of the Company as adividend on the Common Stock, payment by the Company of any cash dividend in excess of $0.05 per quarter per share of Common Stock, and above-market tender offers or exchange offers by the Company or its subsidiaries for the Common Stock. In addition, in certain circumstances, the Company may berequired to increase the conversion rate for any Convertible Notes converted in connection with a make-whole fundamental change as defined in the NoteIndenture.If the Company undergoes a fundamental change, holders may require the Company to repurchase for cash all or part of their Convertible Notes at a purchaseprice equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the date ofrepurchase.Prior to the date that is two years immediately preceding the maturity date, the Company will not have the right to redeem the Convertible Notes. During thetwo year period immediately preceding the maturity date, the Company may redeem for cash all, but not less than all, of the Convertible Notes if the lastreported sale price of the Common Stock equals or exceeds 130% of the conversion price for the Convertible Notes for at least 20 trading days, whether or notconsecutive, during the 30 consecutive trading day period ending on the trading day immediately preceding the date the Company delivers notice ofredemption. If the Company elects to redeem the Convertible Notes, holders may convert their Convertible Notes at any time prior to the close of business onthe business day immediately preceding the redemption date.The Indenture will contain events of default customary for convertible debt securities (with customary grace periods, as applicable) and will provide that,upon the occurrence of an event of default arising from certain events of bankruptcy orF-28 Table of Contentsinsolvency with respect to the Company, all outstanding Convertible Notes will become due and payable immediately without further action or notice. If anyother type of event of default occurs and is continuing, then the holders of at least 25% in aggregate principal amount of the then outstanding ConvertibleNotes or the trustee may declare all of the outstanding Convertible Notes to be due and payable immediately.Convertible Senior Notes due 2018On November 27, 2013, the Company issued $80.0 million principal amount of 4.125% Convertible Senior Notes maturing on December 1, 2018. TheCompany received net proceeds of $77.9 million, after deducting the initial purchasers' discount. These Convertible Senior Notes pay interest semi-annuallyon June 1 and December 1 at a rate of 4.125% per year, which commenced on June 1, 2014. During the first quarter of 2016, the Company repurchased $1.9million in principal amount of the convertible senior notes due in 2018, for an aggregate purchase price of $1.7 million. During the third quarter of 2017, theCompany repurchased $71.8 million in principal amount of the convertible senior notes due in 2018, for an aggregate purchase price of $73.7 million withthe proceeds from the issuance of Convertible Senior Notes due in 2022. As a result we recognized an extinguishment loss of $4.9 million. The Companycurrently intends to settle the remaining outstanding debt in cash upon maturity.The Convertible Senior Notes will be convertible at an initial conversion rate of 83.33 shares of the Company’s common stock per $1,000 principal amount,which is equivalent to an initial conversion price of approximately $12.00. In addition, following certain corporate transactions occurring prior to thematurity date, the Company will, in certain circumstances, increase the conversion rate for a holder electing to convert notes in connection with suchcorporate transaction. Upon conversion, the Company will deliver cash up to the principal amount. With respect to any conversion value in excess of theprincipal amount, the Company will deliver shares of its common stock, unless it elects to deliver cash in lieu of all or a portion of such shares.Holders may convert notes in integral multiples of $1,000 principal amount, at any time prior to the close of business on the business day immediatelypreceding June 1, 2018, but only in the following circumstances:•During any calendar quarter commencing after the calendar quarter ending on March 31, 2014 (and only during such quarter), the last reported saleprice of the Company’s common stock for each of at least 20 of the preceding 30 trading days, ending on and including the last trading day of thequarter exceeds 130% of the conversion price. These days need not be consecutive;•During the five consecutive business day period immediately after any five consecutive trading day period (such 5 consecutive trading day periodbeing referred to as the “measurement period”), in which the trading price (as defined in the offering memorandum) per $1,000 principal amount ofthe notes, as determined following a request by a holder of the notes in the manner described in the offering memorandum, for each trading day ofthe measurement period, was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate onsuch trading day;•Upon the occurrence of specified corporate events (as described in the offering memorandum); or•If the Company has called the notes for redemption (as described in the offering memorandum).In addition, regardless of the foregoing circumstances, holders may convert their notes at any time on or after June 1, 2018 until the close of business on thebusiness day immediately preceding the maturity date.In addition, if the Company undergoes a fundamental change (as defined in the Note indenture), holders may, subject to certain conditions, require theCompany to repurchase their notes for cash at a price equal to 100% of the principal amount of the notes to be purchased, plus accrued and unpaid interest.Under accounting guidance, an entity must separately account for the liability and equity components of a convertible debt instrument that may be settledentirely or partially in cash upon conversion. The separate accounting must reflect the issuer’s economic interest cost. The fair value of the equitycomponent, net of pro-rata initial purchasers’ discounts, is included in the additional paid-in capital section of shareholders' equity in the Company’sConsolidated Balance Sheets. The principal amount of the Convertible Senior Notes is reduced by unamortized original issue discount, which reflects theConvertible Senior Notes fair value. The original issue discount will be amortized over the life of the Convertible Senior Notes due 2022, 2020 and 2018using the effective interest rate of 10.4%, 8.6% and 8.1%, respectively.F-29 Table of ContentsRelevant accounting guidance requires entities to disclose the dilutive effects of convertible instruments. As of December 31, 2017 and 2016, the Company’scommon stock had not met the convertibility criteria noted in the offering memorandum. Therefore, the Convertible Senior Notes were not dilutive as ofDecember 31, 2017 and 2016.The balances of the liability and equity components as of December 31, 2017 and 2016 were as follows (amounts in thousands):December 31, December 31,2017 2016Liability component - principal$158,350 $138,150Deferred bond discount(25,624) (13,213)Deferred financing cost(505) (168)Liability component - net carrying value$132,221 $124,769 Additional paid in capital$39,405 $27,822Discount attributable to equity(826) (419)Equity component$38,579 $27,403Interest expense related to the Convertible Senior Notes, included in Interest expense on long term borrowings in the Consolidated Statements of Operationsand Comprehensive Income, was as follows (amounts in thousands): For the Fiscal Year Ended December 31,2017 2016Interest expense - stated coupon rate$6,535 $5,725Interest expense - amortization of deferred bond discount and costs5,286 4,696Total interest expense - convertible note$11,821 $10,42114. SHARE BASED PAYMENTSTotal share-based compensation expense recognized during 2017, 2016 and 2015 consisted of the following (amounts in thousands): For the Years Ended December 31, 2017 2016 2015Employee compensation and benefits$5,093 $4,151 $3,680On September 30, 2015, the Company’s board of directors adopted the GAIN Capital Holdings, Inc. 2015 Omnibus Incentive Compensation Plan, (the "2015Plan"), which became effective November 30, 2015.The 2015 Plan replaced the GAIN Capital Holdings, Inc. 2010 Omnibus Incentive Compensation Plan, (the “2010 Plan”). The 2015 Plan has available 4.0million shares and no additional shares to be issued pursuant to the 2011 Employee Stock Purchase Plan for awards to employees, nonemployee directors,consultants, and advisors in the form of incentive stock options (“ISO”), nonqualified stock options (“NQSO"), restricted stock awards ("RSA”), restrictedstock units (“RSU”), stock appreciation rights and other stock-based awards. The "evergreen" provision that allowed the Company to authorize additionalshares to be issued under the 2010 plan was removed from the 2015 Plan. Accordingly, the maximum number of shares that can be issued will be fixed andcannot be increased in the future without shareholder approval.Under the 2015 Plan, the Compensation Committee of the Board of Directors (the “Compensation Committee”) will determine the exercise price of theoptions granted and may grant options to purchase shares of the Company’s common stock in amounts as determined by the Compensation Committee. TheCompensation Committee may grant options that are intended to qualify as ISOs under Section 422 of the Internal Revenue Code, or NQSOs which are notintended to so qualify. ISOs may only be granted to employees. Anyone eligible to participate in the 2015 Plan may receive a grant of NQSOs. The exerciseprice of a stock option granted under the 2015 Plan cannot be less than the fair market value of a share of the Company’s common stock on the date theoption is granted. All options granted under the 2015 Plan expire seven years from the date of grant.F-30 Table of ContentsStock OptionsThe following table summarizes the stock option activity under all plans from January 1, 2017 through December 31, 2017 (in thousands, except per shareamounts): Options Outstanding Weighted Weighted Average Number of Average Remaining Aggregate Options Exercise Price Life (Years) Intrinsic ValueOutstanding January 1, 2017 1,393 $6.13 2.96 Granted — — 0.00 Exercised (88) 4.03 3.07 Forfeited/Expired (10) 9.80 4.39 Outstanding December 31, 2017 1,295 $6.25 2.65 $4,857Vested and expected to vest options 1,286 $6.24 2.63 $4,824Exercisable, December 31, 2017 1,033 $5.90 2.07 $4,235 Fair market value of common stock at exercise date $621 Cost to exercise 356 Net value of stock options exercised $265 The total intrinsic value of stock options exercised during 2017, 2016, and 2015, respectively, was $0.3 million, $0.5 million and $3.5 million. During 2017,the Company had 0.2 million stock options vest. The Company received $0.4 million, $0.7 million, and $2.4 million from stock option exercises in 2017,2016, and 2015, respectively.The Company granted 0.2 million and 0.1 million options to employees in 2016 and 2015, respectively. The weighted average grant-date fair value of stockoptions granted in the years ended December 31, 2016 and 2015 was $2.18 and $3.43, respectively. The Company made no option grants in 2017.The Compensation Committee approved stock option grants with a fair market value estimated under a Black-Scholes option pricing valuation model usingthe following assumptions: For the Fiscal Year Ended December 31, 2017 2016 2015Valuation Assumptions Risk-free rateNA 1.19% 1.47%Expected volatilityNA 47.63% 49.08%Expected term (years)NA 4.75 4.75Dividend yieldNA 3.0% 2.1%The expected volatility was calculated on the basis of the volatility of the Company's common stock. The average risk free rate is based upon the risk free rateof the U.S. Treasury bond rate with a maturity commensurate with the expected term.Restricted Stock Units and Restricted Stock AwardsThe 2015 Plan provides for the issuance of RSUs that are convertible on a 1:1 basis into shares of the Company’s common stock. The Company maintains arestricted stock unit account for each grantee. RSU grants typically vest over four years, with 25% vesting on each anniversary date of the grant. After theRSUs vest, the grantee shall receive payment in the form of cash, shares of the Company’s common stock, or a combination of the two, as determined by theCompany. Payment of cash and issuance of shares shall be made upon the vesting date, upon a predetermined delivery date, upon a change in control of theCompany, or upon the employee leaving the Company. The Company has historically settled these awards through the issuance of common stock torecipients and intends to continue to do so. The Company may also issue performance grants, which vestF-31 Table of Contentsimmediately, but under which delivery of the common stock is deferred until a later date. RSUs are assigned the value of the Company’s common stock atdate of grant issuance, and the grant date fair value is amortized over a four year period. During 2017, 2016, and 2015, 1.0 million, 0.9 million and 0.6million RSUs, respectively, were granted to employees and members of the Board of Directors.A summary of the status of the Company’s non-vested shares of RSUs as of December 31, 2017 and changes during the year ended December 31, 2017 arepresented below (in thousands, except per share amounts): Weighted Average Number Grant DateNon-Vested Sharesof RSUs Fair ValueNon-vested at January 1, 20171,474 $7.49Granted963 8.20Vested(572) 7.25Forfeited(140) 7.86Non-vested at December 31, 20171,725 $7.93The total grant-date fair value of RSUs granted during the years ended December 31, 2017, December 31, 2016 and December 31, 2015 was $7.9 million,$6.2 million, and $5.7 million, respectively.As of December 31, 2017, there was $11.5 million of total unrecognized compensation cost related to non-vested share-based compensation arrangementsgranted under the 2015 Plan. The cost is expected to be recognized over a weighted-average period of approximately three years. Employee Stock Purchase PlanThe 2011 Employee Stock Purchase Plan (“ESPP”) was adopted by the Company’s Board of Directors on November 22, 2010. The ESPP became effective onJanuary 1, 2011. The ESPP permits eligible employees to purchase shares of the Company’s common stock at a 15% discount from the lesser of the fairmarket value per share of the Company’s common stock on the first day of the offering period or the fair market value of the Company’s common stock on theinterim purchase date through after-tax payroll deductions. The total number of shares reserved for issuance under the ESPP was initially 500,000. It isintended that the ESPP meet the requirements for an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. For the year endedDecember 31, 2017 and December 31, 2016, 103,042 shares and 96,173 shares were issued under the ESPP, respectively. The discount on the ESPP of $0.1million is recorded in Employee compensation and benefits in the Consolidated Statement of Operations and Comprehensive Income.15. EARNINGS PER COMMON SHAREBasic and diluted (loss)/earnings per common share are computed by dividing net (loss)/income by the weighted average number of common sharesoutstanding during the period. Diluted (loss)/earnings per share includes the determinants of basic net income per share and, in addition, gives effect to thepotential dilution that would occur if securities or other contracts to issue common stock were exercised, vested or converted into common stock, unless theyare anti-dilutive. Diluted weighted average common shares include vested and unvested stock options, unvested restricted stock units and unvested restrictedstock awards. Approximately 0.5 million and 0.2 million stock options were excluded from the calculation of diluted (loss)/earnings per share for the yearsended December 31, 2017 and 2016, respectively, as they were anti-dilutive.Diluted (loss)/earnings per share excludes any shares of Company common stock potentially issuable under the Company’s convertible senior notes, whichare discussed in Note 13. Based upon an assumed trading price of $13 for each share of the Company’s common stock, and if the relevant conditions underthe indenture governing the 2018, 2020, and 2022 convertible senior notes were satisfied, there would be an additional 0.0 million, 1.5 million, and 4.2million dilutive shares as of December 31, 2017 for the 2018, 2020 and 2022 notes, respectively.F-32 Table of ContentsThe following table sets forth the computation of (loss)/earnings per share (amounts in thousands except share and per share data): For the years ended December 31,2017 2016 2015Net (loss)/income applicable to GAIN Capital Holdings, Inc.$(11,195) $35,272 $10,279Adjustment(1)1,656 (2,715) 308Net (loss)/income available to GAIN common shareholders$(9,539) $32,557 $10,587Weighted average common shares outstanding: Basic weighted average common shares outstanding46,740,097 48,588,917 47,601,979Effect of dilutive securities: Stock options245,259 163,223 424,087 RSUs/RSAs35,746 33,534 352,985Diluted weighted average common shares outstanding46,740,097 48,785,674 48,379,051(Loss)/earnings per common share: Basic$(0.20) $0.67 $0.22Diluted$(0.20) $0.67 $0.22 (1)During the years ending December 31, 2017, 2016 and 2015, the Company concluded that the carrying value of the Company’s redeemable non-controlling interests was less than their redemption value, requiring that an adjustment to the carrying value be recorded for purposes of calculatingearnings per common share. The adjustment to increase or reduce the carrying value will, respectively, reduce or increase earnings per common shareby reducing or increasing net income available to common shareholders.16. LEGALFrom time to time the Company becomes involved in legal proceedings and in each case the Company assesses the likely liability and/or the amount ofdamages as appropriate. Where available information indicates that it is probable a liability had been incurred at the date of the consolidated financialstatements and the Company can reasonably estimate the amount of that loss, the Company accrues the estimated loss by a charge to income. In manyproceedings, however, it is inherently difficult to determine whether any loss is probable or even reasonably possible or to estimate the amount of any loss. Inaddition, even where loss is possible or an exposure to loss exists in excess of the liability already accrued with respect to a previously recognized losscontingency, it is often not possible to reasonably estimate the size of the possible loss or range of loss.For certain legal proceedings, the Company can estimate possible losses, additional losses, ranges of loss or ranges of additional loss in excess of amountsaccrued. For certain other legal proceedings, the Company cannot reasonably estimate such losses, if any, since the Company cannot predict if, how or whensuch proceedings will be resolved or what the eventual settlement, fine, penalty or other relief, if any, may be, particularly for proceedings that are in theirearly stages of development or where plaintiffs seek substantial or indeterminate damages. Numerous issues must be developed, including the need todiscover and determine important factual matters and the need to address novel or unsettled legal questions relevant to the proceedings in question, before aloss or additional loss or range of loss can be reasonably estimated for any proceeding.LitigationOn February 16, 2012, the Company received a Letter of Claim on behalf of certain individuals who had lost money in an investment scheme operated by athird-party money management firm, incorporated in the United Kingdom, which has since been closed down by the United Kingdom’s Financial ServicesAuthority. The investment firm, Cameron Farley Ltd, had opened a corporate account with the Company and invested the individuals’ money, representingsuch funds as its own, while operating a fraudulent scheme. Though a complaint had been filed and served on the Company, the claimants requested, and theCompany agreed, to follow the United Kingdom’s Pre-Action Protocol, a pre-litigation process intended to resolve matters without the need to engage informal litigation. On April 28, 2016, the parties entered into a Settlement Agreement in which the Company agreed to make a one-time settlement payment inexchange for a full and final settlement of all claims. For the year ended December 31, 2016, the settlement amount, net of insurance recoveries, totaledapproximately $9.2 million.F-33 Table of Contents17.

Additionally, the impact of foreign taxcredits and the impact on state taxes is provisional. These provisional amounts will be finalized within the measurement period.At December 31, 2017, as a result of the Tax Reform, the Company has changed its position regarding the repatriation of earnings of its foreign subsidiaries.The Company asserts that the earnings of its foreign subsidiaries will be permanently reinvested in the working capital and other business needs of thesubsidiaries to the extent that repatriation of these earnings would trigger additional capital gains and/or foreign withholding taxes. As such, amounts thatcan be brought back without triggering capital gains and/or foreign withholding taxes will not be considered permanently reinvested. Based on our analysis,we do not believe that the potential impact of the unrecognized deferred tax liability associated with the repatriation of such earnings would be material tothe financial statements.At December 31, 2017, the Company did not have any uncertain tax positions.F-36 Table of ContentsThe following table summarizes the activity to the gross unrecognized tax benefits from uncertain tax positions (amounts in thousands):As of December 31,2017 2016 2015Beginning balance as of January 1$4,628 $11,801 $10,517Increases based on tax positions related to the current period— — 885Increases/(decreases) based on tax positions related to prior periods(4,331) (6,617) 429Decreases related to settlements(297) (554) —Decreases related to a lapse of applicable statute of limitations— (2) (30)Ending balance as of December 31$— $4,628 $11,801Included in the balance of unrecognized tax benefits as of December 31, 2017, December 31, 2016, and December 31, 2015 are $0.0 million, $4.6 million and$11.8 million, respectively, of tax benefits that, if recognized, would affect the effective tax rate. The Company’s open tax years range from 2013 through2017 for its U.S. federal returns, from 2015 through 2017 for the U.K., from 2012 through 2017 for Japan, and from 2012 through 2017 for its major statejurisdictions. It is reasonably possible that the amount of liability for unrecognized tax benefits could change during the next 12 months due to openexaminations. An estimate of the range of the possible change cannot be made until issues are further developed or examinations closed.In addition to the total unrecognized tax benefits noted above, the Company recorded $0.0 million, $0.9 million, and $1.8 million of penalties and interestfor the years ended December 31, 2017, December 31, 2016 and December 31, 2015, respectively. These amounts are recorded in Income tax(benefit)/expense in the Consolidated Statements of Operations and Comprehensive Income and are part of the uncertain tax positions impact whenreconciling the federal income tax rate to the Company’s effective tax rate.19. RETIREMENT PLANSThe Company sponsors a “Safe Harbor” 401(k) retirement plan which was put into effect as of January 1, 2011.
