EXPLANATORY NOTE

As used in this Amendment No. 1 to Form 10-Q for the quarter ended March 31, 2014 (the “Form 10-Q/A”), the terms “Company,” “our,” “us”, or “we” refer to GAIN Capital Holdings, Inc., a Delaware corporation and its consolidated subsidiaries.

This Form 10-Q/A amends our Quarterly Report on Form 10-Q for the quarter ended March 31, 2014, as originally filed with the Securities and Exchange Commission (the “SEC”) on May 12, 2014 (the “Original Filing”). This Form 10-Q/A is being filed to restate our unaudited condensed consolidated financial statements for the quarter ended March 31, 2014 and to make corresponding revisions to certain other disclosures in the Original Filing. As further described in Note 14, the restated unaudited condensed consolidated financial statements reflect changes to certain revenue and expense items, the net result of which is to increase net income for the three months ended March 31, 2014 from $1.7 million to $3.8 million and diluted earnings per share for the three months ended March 31, 2014 from $0.04 to $0.09.

This Form 10-Q/A amends and restates in its entirety each section of the Original Filing that was required to be revised as a result of the restatement, but each section that has been restated has been updated solely to reflect the changes described in Note 14. Except as provided above, this Form 10-Q/A does not include sections of the Original Filing that were not required to be updated as a result of the restatement. In addition, this Form 10-Q/A has not been updated to reflect events occurring after May 12, 2014, the date of the Original Filing. Therefore, this Form 10-Q/A should be read in conjunction with filings we have made with the SEC subsequent to May 12, 2014.

1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Description of Business

GAIN Capital Holdings, Inc., together with its subsidiaries (the “Company”), is a Delaware corporation formed and incorporated on March 24, 2006. GAIN Holdings, LLC is a wholly-owned subsidiary of GAIN Capital Holdings, Inc., and owns all outstanding membership units in GAIN Capital Group, LLC (“Group, LLC”), the primary regulated entity in the United States of America.

Group, LLC is a retail foreign exchange dealer (“RFED”) and a registered Futures Commission Merchant (“FCM”) with the Commodity Futures Trading Commission (“CFTC”). As such, it is subject to the regulations of the CFTC, an agency of the U.S. Government, and the rules of the National Futures Association (“NFA”), an industry self-regulatory organization.

The following list includes each of the Company’s significant U.S. and international regulated subsidiaries:

GAIN Capital Group, LLC

GAIN Capital-Forex.com U.K., Ltd.

Forex.com Japan Co., Ltd.

GAIN Capital Forex.com Australia Pty. Ltd.

GAIN Capital-Forex.com Hong Kong Ltd.

GAIN Capital-Forex.com Canada, Ltd.

GAIN GTX, LLC

GAIN GTX SEF, LLC

Global Futures & Forex, Ltd.

GFT Global Markets UK Ltd.

GFT Global Markets Asia Pte., Ltd.

In March 2014, the Company acquired controlling interests in Global Asset Advisors, LLC ("GAA") and Top Third Ag Marketing LLC ("TT").

In September 2013, the Company purchased all of the outstanding share capital of Global Futures & Forex, Ltd., a Michigan corporation ("GFT").

See note 5 "Acquisitions" for further details related to these acquisitions.

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements reflect all adjustments, all of which are normal recurring adjustments that, in the opinion of management, are necessary for a fair presentation of the financial statements for the interim periods. The unaudited condensed consolidated financial statements have been prepared in accordance with the regulations of the Securities and Exchange Commission ("SEC") for interim financial statements, and, in accordance with SEC rules, omit or condense certain information and footnote disclosures. Results for the interim periods are not necessarily indicative of results to be expected for any other interim period or for the full year. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 filed with the SEC on March 17, 2014 (the “2013 Form 10-K”). There have been no changes in the significant accounting policies from those included in the 2013 Form 10-K. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, after the elimination of inter-company transactions and balances.

In an effort to align the presentation of expenses with competitors in the industry in order to enable easier comparisons, the Company has presented commissions paid to employees, previously presented in "Trading expenses and commissions" under "Employee compensation and benefits." Additionally, the Company has presented compensation paid to its white label partners and introducing brokers, which was also previously presented in "Trading expenses and commissions," under the new caption of "Referral fees." The remaining items that were previously presented in "Trading expenses and commissions," including exchange fees, fees for news services and prime broker fees, are now presented under a new caption, "Trading expenses." These changes in presentation had no effect on the total expenses.

2. RECENT ACCOUNTING PRONOUNCEMENTS

In July 2013, the Financial Accounting Standards Board, ("FASB") issued Accounting Standards Update (“ASU”) No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU 2013-11 requires presenting unrecognized tax benefits netted against deferred tax assets, if such assets are sufficient and expected to replace cash payment, should an uncertain tax position not be sustained. This update is currently in effect. The Company has applied this update in 2014. The Company believes that it does not materially affect the three months ending March 31, 2014.

3. ADDITIONAL FINANCIAL INFORMATION

Fair Value Measurement

The following table presents the Company’s assets and liabilities that are measured at fair value on a recurring basis during the period and the related hierarchy levels (amounts in thousands):

Total	$	21,927	$	119,320		$	—	$	141,247

The Company has not changed its valuation techniques in measuring the fair value of any financial assets and liabilities during the period.

Level 1 Financial Assets

The Company has money market accounts, certificates of deposit, CIBC treasury bills and an investment in gold that are Level 1 financial instruments that are recorded based upon listed or quoted market rates. The money market accounts are recorded in Cash and cash equivalents and Cash and securities held for customers, the treasury bills are recorded in Cash and cash equivalents and Short term investments, based upon their maturity, the certificates of deposit are recorded in Short term investments and the investment in gold is recorded in Receivables from banks and brokers.

10

Level 2 Financial Assets and Liabilities

The Company has open contracts and other positions that are Level 2 financial instruments that are recorded in Receivables from banks and brokers.

The Company has customer and broker open contracts and other positions that are Level 2 financial instruments that are recorded in Payable to customers, brokers, dealers, FCMs and other regulated entities.

These Level 2 financial instruments are based upon directly observable values for underlying instruments.

Financial Instruments Not Measured at Fair Value

The table below presents the carrying value, fair value, and fair value hierarchy category of certain financial instruments that are not measured at fair value in the Condensed Consolidated Balance Sheet (amounts in thousands). The carrying value of Receivables from banks and brokers not measured at fair value approximates fair value because of the relatively short period of time between their origination and expected maturity. The carrying value of Payables to customers, brokers, dealers, FCMs, and other regulated entities includes amounts deposited by these customers and financial institutions in order for the Company to act as a clearing broker. The carrying value of Payables to customers, brokers, dealers, FCMs, and other regulated entities includes cash and open positions. The carrying value of Convertible senior notes represents the notes’ principal amounts net of unamortized discount (see note 7). We assessed the notes' fair value against prevailing interest rates as of the balance sheet date. The carrying value of Accrued expense and other liabilities includes $20.0 million, referred to as the Holdback Amount, to be paid net of an amount required to settle certain liabilities of GFT after the closing date of the acquisition (see note 5). The carrying values of Accrued expense and other liabilities not measured at fair value approximate fair value because of the relatively short period of time between their origination and expected settlement date.

The preliminary purchase price allocations to intangible assets are detailed below in Note 5, “Acquisition”.

In 2003, the Company acquired the Forex.com domain name for $0.2 million, and in 2004, the foreignexchange.com domain name was purchased for $0.1 million. Because the rights to use these domain names require the payment of a nominal annual renewal fee, management determined that there was no legal, regulatory or technological limitation on their useful lives. Accordingly, these indefinite-lived assets are not amortized. In accordance with ASC 350-10, the Company tests intangible

14

assets for impairment on an annual basis in the fourth quarter and on an interim basis when conditions indicate impairment may have occurred.

Amortization expense for the purchased intangibles was $1.0 million and $0.6 million for the three months ended March 31, 2014 and 2013, respectively.

Goodwill

Goodwill is calculated as the difference between the cost of acquisition and the fair value     of the net identifiable assets of an acquired business. As of March 31, 2014 and December 31, 2013, the Company had recorded goodwill of approximately $26.1 million and $14.2, respectively.

Goodwill increased $5.5 million as a result of the GAA acquisition, $4.7 million as a result of the TT acquisition, and $6.2 million as a result of the GFT acquisition. The $6.2 million arising from the GFT acquisition was adjusted from the amount reported at December 31, 2013, as part of preliminary purchase accounting.

The actual amount required to settle the remaining liabilities may vary from this estimate.

Under the terms of the acquisition of GFT, the selling stockholder of GFT has agreed to indemnify the Company for these liabilities that are expected to be settled after September 24, 2013. Based on the Company's best estimate of the amounts necessary to settle such liabilities, the Company recorded an indemnification asset of $8.6 million at March 31, 2014.

6. NON-CONTROLLING INTEREST

Non-controlling interests

In March 2014, the Company acquired controlling interests in GAA and TT. The Company purchased 55% of each entity, and the respective sellers maintained a 45% interest in each entity. The 45% interests are redeemable at prices determined by applying a contractually agreed upon formula to the respective acquired company's financial results. The Company owns

18

immediately vested call options to purchase the remaining interests in each company. The minority owners hold put options, which vest in 2017 or upon the occurrence of certain events, to compel the Company to purchase the remaining interests.

The non-controlling interests are not classified as liabilities, because redemption is not mandatory or at fixed prices. They are not classified as equity, because their redemption is not exclusively in the Company's control. Therefore, the non-controlling interests are held in temporary equity in the Condensed Consolidated Balance Sheets.

The non-controlling interests' carrying value is determined by the Company's purchase prices and the non-controlling interests' share of the Company's subsequent 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 prices allocation. The Company has made a policy election to reflect any changes caused by such an adjustment in retained earnings, rather than in current earnings. The Company recorded no such adjustment for the three months endedMarch 31, 2014.

The table below reflects the non-controlling interests effects on the Company's financial statements:

	Redeemable non-controlling interests
December 31, 2013	$	—
Non-controlling interests related to 2014 acquisitions	8,395
Net income attributable to non-controlling interests	38
March 31, 2014	$	8,433

7. CONVERTIBLE SENIOR NOTES

Convertible Senior Notes due 2018

On November 27, 2013, the Company issued $80.0 million aggregate principal amount of its 4.125% Convertible Senior Notes maturing on

December 1, 2018. The Company received net proceeds of $77.9 million, after deducting the initial purchasers' discount. The

Convertible Notes pay interest semi-annually on June 1 and December 1 at a rate of 4.125% per year, commencing June 1,

2014.

Under ASC 470, an entity must separately account for the liability and equity components of a convertible debt instruments that

may be settled entirely or partially in cash upon conversion. The separate accounting must reflect the issuer's economic interest

cost.

The balances of the liability and equity components as of March 31, 2014, and December 31, 2013 were as follows, with amounts in thousands:

	March 31,			December 31,
	2014			2013

Interest expense - amortization of deferred bond discount and costs	612
Total interest expense - convertible note	$	1,437

8. SHARE BASED COMPENSATION

During the three months ended March 31, 2014, 0.4 million shares of restricted stock and approximately 0.1 million options to purchase common stock, valued at $3.7 million and $0.4 million, respectively, were granted to employees and non-employee members of the Board of Directors, compared to 0.8 million shares of restricted stock and 0.3 million options to purchase common stock, valued at $3.6 million and $0.6 million, respectively during the three months ended March 31, 2013.

The Company determines the fair value of restricted stock units and awards at the date of grant based on the value of the Company’s common stock. The Company determines the fair value of our stock option awards at the date of grant using a Black-Scholes valuation model. This model requires assumptions and judgments on the expected volatility, dividend yield, the risk-free interest rate and the expected term of the stock options. The following assumptions were used for stock options granted in the period:

	For the Three Months Ended March 31,
	2014	2013
Valuation Assumptions
Risk-free rate	1.4%	0.8%
Expected volatility	51.8%	48.8%
Expected term (years)	4.75	4.75
Dividend yield	2.0%	4.9%

9. EARNINGS PER COMMON SHARE

Basic and diluted earnings per common share are computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share includes the determinants of basic net income per share and, in addition, gives effect to the potential dilution that would occur if securities or other contracts to issue common stock were exercised, vested or converted into common stock, unless they are anti-dilutive. Diluted weighted average common shares include vested and unvested stock options, vested restricted stock units which are to be delivered as soon as administratively practicable on or after December 31, 2014, unvested restricted stock units and unvested restricted stock awards. Approximately 1.1 million and 0.6 million stock options were excluded from the calculation of diluted earnings per share for the three months ended March 31, 2014 and the three months ended March 31, 2013, respectively, as they were anti-dilutive.

20

The following table sets forth the computation of earnings per share (amounts in thousands except share and per share data):

	For the Three Months Ended March 31,
	2014		2013
Net income applicable to GAIN Capital Holdings, Inc. (As Restated see Note 14)	$	3,825	$	4,279
Adjustment(1)	—		(154		)
Net income applicable to GAIN common shareholders	$	3,825	$	4,125
Weighted average common shares outstanding:
Basic weighted average common shares outstanding	39,543,586		35,052,375
Effect of dilutive securities:
Stock options	956,445		851,451
RSUs/RSAs	2,127,597		1,427,766
Diluted weighted average common shares outstanding	42,627,628		37,331,592
Earnings per common share
Basic	$	0.10	$	0.12
Diluted	$	0.09	$	0.11

(1) During the period an adjustment to retained earnings was made, reflecting the amounts deemed uncollectible associated with previously issued preferred stock, which was converted to common stock immediately prior to the IPO.

10. LEGAL

From time to time the Company becomes involved in legal proceedings and in each case the Company assesses the likely liability and/or the amount of damages as appropriate. Where available information indicates that it is probable a liability had been incurred at the date of the condensed consolidated financial statements and the Company can reasonably estimate the amount of that loss, the Company accrues the estimated loss by a charge to income. In many proceedings, however, it is inherently difficult to determine whether any loss is probable or even possible or to estimate the amount of any loss. In addition, even where loss is possible or an exposure to loss exists in excess of the liability already accrued with respect to a previously recognized loss contingency, 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 amounts accrued. For certain other legal proceedings, the Company cannot reasonably estimate such losses, if any, since the Company cannot predict if, how or when such proceedings will be resolved or what the eventual settlement, fine, penalty or other relief, if any, may be, particularly for proceedings that are in their early stages of development or where plaintiffs seek substantial or indeterminate damages. Numerous issues must be developed, including the need to discover and determine important factual matters and the need to address novel or unsettled legal questions relevant to the proceedings in question, before a loss or additional loss or range of loss or additional loss can be reasonably estimated for any proceeding.

Litigation

On 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 a third-party money management firm, incorporated in the United Kingdom, which has since been closed down by the United Kingdom’s Financial Services Authority. The investment firm, Cameron Farley Ltd, had opened a corporate account with the Company and invested the individuals’ money, representing such funds as its own, while operating a fraudulent scheme. Though a complaint has been filed and served on the Company, the claimants requested, and the Company agreed, to follow the United Kingdom’s Pre-Action Protocol, a pre-litigation process intended to resolve matters without the need to engage in formal litigation. The Company submitted a Response to the Letter before Claim on July 4, 2012. On July 5, 2012 the Company received a substantially similar Letter of Claim on behalf of further individuals. Subsequently, the parties agreed to consolidate claims by those other similarly situated individuals with the pending Pre-Action Protocol process. The parties agreed it would be more appropriate for the proceedings to be dealt with in the Commercial Court and the matters were transferred pursuant to Consent Orders dated March 14, 2013. The Company subsequently filed an application for strike out and/or summary judgment in respect of all claims on March 15, 2013. The claimants filed an answer to the Company's motion on June 2, 2013 and subsequently the Company filed a response to this answer on July 15, 2013. A hearing was held on the Company's application for strike out and/or summary judgment on September 18 and 19, 2013.  After the

21

hearing, the judge asked the claimants to respond in writing to his additional questions from the hearing.  The complaints had until October 11, 2013 to provide answers and the Company was given until November 1, 2013 to respond.  On February 26, 2014, the judge denied the Company's motion for strike out/ summary judgment. The Company can provide no assurances that this matter will be successfully resolved. This matter is currently pending. As of the date of this report, a potential loss or a potential range of loss cannot be reasonably estimated.

Through the Company's acquisition of OEC, the Company became the subject of a patent infringement lawsuit originally filed against OEC on February 9, 2010 in the U.S. District Court for the Northern District of Illinois by Trading Technologies International, Inc. seeking injunctive relief and unspecified damages. As reflected in a Second Amended Complaint filed on June 15, 2011, plaintiff alleges infringement of 12 patents relating to real-time display of price quotes and market depth on OEC's electronic trading interfaces. The case was consolidated with 11 related cases in February 2011, and the parties have exchanged infringement, non-infringement and invalidity contentions for several of the disputed patents. In June 2011, the court stayed discovery to allow summary judgment briefing on the ramifications of a recent Federal Circuit decision. On February 9, 2012, the court issued an order, which granted defendants' motions for summary judgment, resulting in a substantial narrowing of the scope of plaintiff's claims. Plaintiff filed a motion for reconsideration of that ruling on March 8, 2012. Plaintiff also filed a motion for certification of judgment for interlocutory appeal. The court denied plaintiff's motion for reconsideration but granted plaintiff's motion for certification of judgments of patent invalidity with respect to four of the asserted patents. On August 30, 2013, the Federal Circuit issued its opinion vacating and remanding the court's judgment of patent invalidity regarding four of the asserted patents. On remand, defendants renewed their motion for summary judgment of patent invalidity. In April 2014, the court deferred its consideration of defendants' renewed motion for summary judgment and signaled its intent to re-start the litigation by requesting that the parties submit a proposed pre-trial schedule. Plaintiff's complaint does not specify the amount of damages sought. As of the date of this report, a potential loss or a potential range of loss cannot be reasonably estimated.

11. INCOME TAXES

The Company’s provision for income taxes was approximately $1.3 million and $0.9 million for the three months ended March 31, 2014 and the three months ended March 31, 2013, respectively. The 2014 amount has been adjusted from the originally filed amount to properly account for amendments to the Company's condensed consolidated statement of operations. These amounts reflect effective tax rates of 24.8% and 16.9%, respectively. The Company's effective tax rate of 24.8% for the three months ended March 31, 2014 reflects the Company's estimate of the annual effective tax rate adjusted for certain discrete items. For the three months ended March 31, 2014 there was a $0.6 million reduction in the provision for income taxes resulting from the conclusion of a NJ State tax audit.

Deferred income taxes reflect the net tax effects of temporary differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when such differences are expected to reverse. The Company’s net deferred tax assets are included in Other assets on the Condensed Consolidated Balance Sheet.

As compared to amounts reported in the Company’s Annual Report on Form 10-K filed on March 17, 2014, regulatory requirements decreased approximately $12.5 million, primarily related to capital charges at the Company's UK regulated affiliates.

13. SEGMENT INFORMATION

ASC 280, Disclosures about Segments of an Enterprise and Related Information, establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-maker, or decision making group, in deciding how to allocate resources and in assessing performance. Reportable segments are defined as an operating segment that either (a) exceeds 10% of revenue, or (b) reported profit or loss in absolute amount exceeds 10% of profit of all operating segments that did not report a loss or (c) exceeds 10% of the combined assets of all operating segments. The Company’s operations relate to global trading services and solutions. Based on the Company’s management strategies, and common production, marketing, development and client coverage teams, the Company has concluded that it operates in a single operating segment.

14. RESTATEMENT

Subsequent to the date of the Original Filing, the Company concluded that it was required to restate its unaudited interim condensed consolidated financial statements as of and for the quarter ended March 31, 2014 to make the following changes to the Original Filing:

• Trading activity from some of the Company's omnibus partners that took place on March 31, 2014 was incorrectly recorded on April 1, 2014. Such trading activity should have been included in the first quarter's results, because the revenue was earned and realizable as of March 31, 2014. As a result of this omission, the Company understated its trading revenue for the first quarter of 2014 by $4.2 million.

• Expenses are recorded when goods are received or services performed; this is often in advance of payment, resulting in the recording of a corresponding liability. The Company operates a payment process that automatically results in an expense being recorded when cash is paid. To prevent double counting of expenses the original liability is released at that time. On March 31, 2014, the Company incorrectly assumed a payment to a partner had taken place for services performed in the first quarter of 2014 and therefore incorrectly released the related liability. The payment was actually made on April 1, 2014. As a result, the Company understated referral fees and the related accrual in the first quarter of 2014 by $1.0 million.

• The Company provides its customers market data received from various exchanges and uses the data to derive prices for certain of its products. The Company pays various fees to these exchanges based on the use of market data by the Company and, in some cases, its customers. These fees are based on a number of factors. In estimating these expenses for the first quarter of 2014, the Company did not utilize all relevant information available at the time and, as a result, understated its trading expenses and the related accrual by $0.6 million.

• The Company incorrectly recorded depreciation on an asset that was under construction and not yet in service. As a result, the Company overstated its depreciation expense in the first quarter of 2014 by $0.5 million.

The previously filed unaudited interim condensed consolidated financial statements for the quarter ended March 31, 2014 have been restated to reflect the changes described above and their applicable income tax effects. The following tables reflect the financial statement line items impacted, together with the adjusted amounts. For the avoidance of doubt, the following tables include only those line items impacted by the restatement:

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FORWARD-LOOKING INFORMATION

In this Quarterly Report on Form 10-Q/A, the words “GAIN”, the “Company”, “our”, “we” and “us” refer to GAIN Capital Holdings, Inc. and, except as otherwise specified herein, to GAIN’s subsidiaries. Our fiscal quarter ended on March 31, 2014.

This 10-Q/A amends the 10-Q originally filed on May 12, 2014. The following discussion incorporates the amended results.

The following discussion of the financial condition and results of operations of the Company should be read in conjunction with the Selected Financial Data and the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013, and the Condensed Consolidated Financial Statements and Notes thereto contained in this Quarterly Report on Form 10-Q/A. This Quarterly Report on Form 10-Q/A contains a number of forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These forward-looking statements are based on current expectations, estimates, forecasts and projections about the industry and markets in which we operate and management’s current beliefs and assumptions. Any statements contained herein (including, without limitation, statements to the effect that we “believe”, “expect”, “anticipate”, “plan” and similar expressions) that are not statements of historical fact should be considered forward-looking statements and should be read in conjunction with the Condensed Consolidated Financial Statements and Notes thereto included in this report and the discussion below. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. There are a number of important factors that could cause actual results to differ materially from those indicated by such forward-looking statements. Such factors include those set forth in the section entitled “Item 1A – Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2013, and discussed elsewhere in this Quarterly Report on Form 10-Q/A. The risks and uncertainties described therein and herein are not the only ones we face. Additional risks and uncertainties, including those not presently known to us or that we currently deem immaterial, may also impair the business. We expressly disclaim any obligation to update any forward-looking statements, except as may be required by law.

OVERVIEW

We are a global provider of trading services and solutions, specializing in over-the-counter, or OTC, and exchange-traded markets. We service retail and institutional customers in more than 180 countries worldwide and conduct business from our offices in New York, New York: Bedminster, New Jersey; Chicago, Illinois: Powell, Ohio; Grand Rapids, Michigan; London, England; Tokyo, Japan; Sydney, Australia; Beijing, China; Hong Kong and Singapore.

We offer our customers access to a diverse range of over 12,500 financial products, including foreign exchange, or forex, precious metals, “contracts for difference”, or CFDs, which are investment products with returns linked to the performance of underlying commodities, indices, individual equities, bonds and interest rate products, OTC options on forex, as well as futures and options on futures on more than 30 global exchanges and binaries. In the United Kingdom, we also offer spread bets, which are investment products similar to CFDs, but that offer more favorable tax treatment to residents of that country.

We have invested considerable resources since our inception to develop our proprietary trading platforms to provide our customers with advanced price discovery, trade execution and order management functions, while improving our ability to acquire and service our customers efficiently, as well as manage market and credit risk associated with our customer’s trading activity. Today our customers can trade through web-based, downloadable and mobile trading platforms and have access to innovative trading tools to assist them with research and analysis, automated trading and account management.

Market Overview

Overall market conditions were challenging during the three months ended March 31, 2014.  During this period, volatility in several of the major currencies decreased and reached 5-year lows, and trading in these currencies generally occurred within narrow price ranges.  In general, lower levels of market volatility negatively impact our ability to generate revenue on trading volumes in our retail OTC business.  To a lesser degree, we believe these market conditions decreased client engagement in our institutional and exchange-traded futures businesses.  Notwithstanding the challenges we faced during the first quarter in terms of financial results, most of our key operating metrics experienced strong growth, which we believe is a positive indicator of our ability to generate increased trading revenues when market conditions improve.

Global Asset Advisors, LLC and Top Third Ag Marketing LLC Acquisitions

On March 7, 2014, we entered into a Membership Interest Purchase Agreement (the "GAA Agreement") with Global Asset Advisors, LLC ("GAA"), Lucky Good Dog, L.L.C. ("LGD"), Glenn A. Swanson and Andrew W. Daniels (as sellers' representative). On March 21, 2014, upon the terms and subject to the conditions set forth in the GAA Agreement, we purchased 55% of the outstanding membership interests in GAA from LGD and Mr. Swanson (collectively, the "GAA Sellers") for an aggregate purchase price consisting of (i) $4,420,240 in cash and (ii) 116,801 shares of the Company's common stock. The purchase price is subject to upwards or downwards adjustment based on GAA's working capital and cash at the closing date. Under the terms of the GAA Agreement, LGD and Mr. Swanson are also entitled to receive, for a period of seven years after the closing of the acquisition, annual payments of a portion of the net interest earned on the assets of clients of GAA at the time of the closing. Under the terms of the Amended and Restated Operating Agreement of GAA, which was executed at the closing of the acquisition, we have, for a period of six years after the closing, a call right to purchase the remaining membership interests in GAA for a price based on a multiple of GAA's trailing twelve month EBITDA. From the third anniversary through the sixth anniversary of the closing date, the GAA Sellers may put their remaining interests in GAA to us on the same terms.

Also on March 7, 2014, we entered into a Membership Interest Purchase Agreement (the "Top Third Agreement") with Top Third Ag Marketing LLC ("Top Third"), LGD, Mark Gold and Glenn A. Swanson. On March 21, 2014, upon the terms and subject to the conditions set forth in the Top Third Agreement, we purchased 55% of the outstanding membership interests in Top Third from LGD and Messrs. Gold and Swanson (collectively, the "Top Third Sellers") for an aggregate purchase price consisting of $4,749,289, a portion of which will be payable to Mr. Gold contingent upon satisfying certain requirements over the three year period following the closing date of the acquisition. The purchase price is subject to upwards or downwards adjustment based on Top Third's cash at the closing date. Under the terms of the Amended and Restated Operating Agreement of Top Third, which was executed on the closing of the acquisition, we have, for a period of six years after the closing, a call right to purchase the remaining membership interests in Top Third for a price based on a multiple of Top Third's trailing twelve month EBITDA. From the third anniversary through the sixth anniversary of the closing date, the Top Third Sellers may put their remaining interests in Top Third to us on the same terms.

Key Income Statement Line Items and Key Operating Metrics

The following table sets forth key financial metrics for our business for the periods indicated:

	For the Three Months Ended March 31,
	2014		2013
Net revenue	$	79,938	$	49,765
Net income applicable to Gain Capital Holdings, Inc.	$	3,825	$	4,279

Revenue

We generate revenue from trading revenue, commission revenue, other revenue and interest income.

Trading Revenue

Trading revenue is our largest source of revenue and has traditionally been primarily generated in our retail forex business. Trading revenue represented 64.1% of our total net revenue for the three months ended March 31, 2014 and 71.0% of our total net revenue for the three months ended March 31, 2013.

We generate trading revenue as follows:

• for trades that are naturally hedged against an offsetting trade from another customer, we receive the entire retail bid/offer spread we offer our customers on the two offsetting transactions;

• for trades that are hedged with one of our wholesale trading partners, we receive the difference between the retail bid/offer spread we offer our customers and the wholesale bid/offer spread we receive from the wholesale trading partners; and

• with respect to the remaining customer trades, which we refer to as our net exposure, we receive the net gains or losses generated through changes in the market value of the currencies held in our net exposure.

29

For the three months ended March 31, 2014, approximately 94% of our average daily retail trading volume was either naturally hedged or hedged by us with one of our wholesale forex trading partners, and the remaining 6% of our average daily retail trading volume consisted of our net exposure, compared to average daily retail trading volume hedged of approximately 98% for the three months ended March 31, 2013.

We manage our net exposure by applying position and exposure limits established under our risk-management policies and by continuous, active monitoring by our traders. Based on our risk management policies and procedures, over time a portion of our net exposure may be hedged with our wholesale forex trading partners. Although we do not actively initiate proprietary directional market positions in anticipation of future movements in the relative prices of the products we offer, through our net exposure we are likely to have open positions in various currencies at any given time. In the event of unfavorable market movements, we may take a loss on such positions.

Commission Revenue

Commission revenue has historically been comprised of revenue from our GTX business, revenue from our futures business, and revenue from GAIN Securities, our securities business. In October 2013, GAIN Securities transferred substantially all of its customer accounts to TradeKing, LLC.  As a result of acquiring GFT in September 2013, we have also realized commission revenue from the sales trader business acquired from GFT.  Our sales traders offer high-touch trading services to high net worth individuals.

The businesses discussed above generally generate revenue by earning a commission on each transaction, which is recorded under commission revenue. On a volume basis, the revenue generated by our commission business is typically lower than that of our trading business.

Other Revenue

Other revenue is comprised of account management, transaction and advisory fees; inactivity and training fees charged to customer accounts; foreign currency transaction gains and losses; and other miscellaneous items from each of our businesses.

Net Interest Revenue / Expense

Net 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 with our wholesale forex trading partners, less interest expense on our Convertible Senior Notes.

Our cash and customer cash is generally invested in money market funds, which primarily invest in short-term U.S. government securities or treasury bills. Such deposits and investments earned interest at an average effective rate of approximately 0.1% for the three months ended March 31, 2014 and 2013. Interest paid to customers varies among customer accounts primarily due to the net value of a customer account. From time to time, we also make available interest promotions pursuant to which we may pay certain customers higher levels of interest than that which is paid to other customers. Interest income and interest expense are recorded when earned and incurred, respectively. Net interest expense was $1.1 million for the three months ended March 31, 2014. There was no net interest in the three months ended March 31, 2013.

Expenses

Our expenses are principally comprised of employee compensation and benefits, selling and marketing, referral fees, trading expenses and other expenses.

In an effort to align the presentation of expenses with competitors in the industry in order to enable easier comparisons, we have presented commissions paid to employees, previously presented in "Trading expenses and commissions" under "Employee compensation and benefits." Additionally, we have presented compensation paid to our white label partners and introducing brokers, which was also previously presented in "Trading expenses and commissions," under the new caption of "Referral fees." The remaining items that were previously presented in "Trading expenses and commissions", including exchange fees, fees for news services and prime broker fees, are now presented under a new caption, "Trading expenses." These changes in presentation had no effect on the total expenses.

Employee Compensation and Benefits

Employee compensation and benefits includes salaries, commissions, bonuses, stock-based compensation, contributions to benefit programs and other related employee costs.

30

Selling and Marketing

Our 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. For the three months ended March 31, 2014, selling and marketing expense was $6.1 million, compared to $5.4 million for the three months ended March 31, 2013.

Referral Fees

Referral fees consists 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 trading customers to us. White labels and introducing brokers market to and locate customers, while providing us with trade flow.

Referral fees are largely variable and change principally based on the level of customer trading volume directed to us from our white label partners and introducing brokers, the specific terms of our agreements with the white label partners and introducing brokers, which vary on a partner-by-partner and regional basis, and the relative percentage of trading volume generated from particular relationships in any given period. The majority of our white label and introducing broker partners are paid based on the trading volume generated by the customers they introduce, directly or indirectly, to us, rather than on a revenue sharing basis. As such, during periods in which their customers’ trading activity is not profitable for us, if the associated trading volume remains high, we may be required to make larger payments to these partners despite the fact that we are generating lower revenue from their customers.  Our indirect business accounted for 48.0% of retail trading volume in the three months ended March 31, 2014 and 34.8% for the three months ended March 31, 2013.

Trading expenses

Trading expenses consists of exchange fees paid to stock exchanges and other third-parties for exchange market data that we provide to our customers or use to create our own derived data products, as well as fees for news services and fees paid to prime brokers in connection with our institutional GTX business and futures business.

General and Administrative

General and administrative expenses consist of bank fees, professional fees, occupancy and equipment and other miscellaneous expenses.

Depreciation and amortization

Depreciation and amortization consists of the recognition of expense for physical assets and software purchased for use over a period of several years and of the amortization for internally developed software.

Purchased Intangible Amortization

Purchased intangible amortization consists of amortization related to intangible assets we acquired in 2013, 2012 and 2011 in connection with our acquisition of customer accounts in several transactions we executed during these periods. The principal intangible assets acquired were customer assets and a non-compete agreement. These intangible assets have useful lives ranging from one year to six years.

Communications and Technology

Communications and technology consists of communications fees, product development, software and maintenance expenses.

Bad debt provision

Bad debt provision represents the amounts estimated for the uncollectibility of certain outstanding balances during the period.

Restructuring Expenses

For the three months ended March 31, 2014, we incurred restructuring expenses, which reflected costs arising from headcount reductions and other exit costs, measured and disclosed in accordance with ASC 420 and ASC 712.

Acquisition Expenses

For the three months ended March 31, 2014, we incurred acquisition related expenses, which included non-recurring costs, such as legal, accounting, valuation and other costs specified in ASC 805. These costs are expensed as incurred.

31

Integration Expenses

For the three months ended March 31, 2014, we incurred integration expenses, which are non-recurring acquisition related costs that do not meet the definition of acquisition costs specified in ASC 805. These costs include retention bonuses paid to employees and the cost of retiring redundant assets.

Operating Metrics

The following table sets forth key operating metrics for our business for the periods indicated:

	For the Three Months Ended March 31,
	2014		2013
Retail
Funded Accounts	134,685		100,016
Active OTC Accounts	97,253		62,595
Futures Contracts	1,609,796		1,282,066
OTC Trading Volume (billions)	$	566.3	$	431.8
OTC Average Daily Volume (billions)	$	9.0	$	6.7
Client Assets (millions)	$	801.0	$	456.9
Institutional
Institutional Trading Volume (billions)	$	1,348.4	$	889.9
Institutional Average Daily Volume (billions)	$	21.4	$	13.9

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 that generally impact the market for leveraged trading, as well as 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 by the following 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 and increasing overall customer trading activity.

For the three months ended March 31, 2014 and March 31, 2013, no single retail customer accounted for more than 2.0% of our retail trading volume for the period.

Funded Accounts

Funded accounts represent retail customers who maintain cash balances with us. We believe the number of funded retail accounts is an important indicator of our ability to attract new retail customers that can potentially lead to trading volume and revenue in the future; however, it does not represent actual trades executed.

Active OTC Accounts

Active OTC accounts represents customers who executed at least one trade during the relevant period. We believe active OTC accounts is an important operating metric because it correlates to our trading volume and revenue.

Futures Contracts

Futures contracts represent the total number of contracts transacted by customers of our futures division.

32

OTC Trading Volume

OTC trading volume is the U.S. dollar equivalent of the aggregate notional value of OTC trades executed by our retail customers. Approximately 29.6% of our customer trading volume for the three months ended March 31, 2014 was generated by our retail businesses, compared to 32.7% for the three months ended March 31, 2013, respectively.

Average Daily Volume

Average 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 the number of trading days in the given period.

Client Assets

Client assets represent amounts due to clients, including customer deposits and unrealized gains or losses arising from open positions.

Institutional Trading Volume

Trading volume is the U.S. dollar equivalent of the aggregate notional value of OTC trades executed by our institutional customers. Approximately 70.4% of our customer trading volume for the three months ended March 31, 2014, respectively, was generated by our institutional trading business, compared to 67.3% for the three months ended March 31, 2013.

RESULTS OF OPERATIONS

Revenue

	Three Months Ended March 31,
	(amounts in thousands)
	2013			2012
REVENUE:
Trading revenue	$	51,204		$	35,313
Commission revenue	29,800			10,833
Other revenue	83			3,608
Total non-interest revenue	81,087			49,754
Interest revenue	363			118
Interest expense	1,512			107
Total net interest (expense) / revenue	(1,149		)	11
Net revenue	$	79,938		$	49,765

Our total net revenue increased$30.2 million, or 60.6%, for the three months ended March 31, 2014, compared to the three months ended March 31, 2013.

Trading revenue increased$15.9 million, or 45.0%, for the three months ended March 31, 2014, compared to the three months ended March 31, 2013. The increase was primarily attributable to our acquisition of GFT in September 2013, partially offset by decreased retail revenue capture resulting from challenging trading conditions during the quarter ended March 31, 2014, with currency volatility levels reaching 5-year lows.

Commission revenue increased $19.0 million, or 175.1%, for the three months ended March 31, 2014, compared to the three months ended March 31, 2013. The increase was due to an additional $2.7 million from our GTX business, as well as an increase of $1.7 million from our futures business. Our sales trader business, acquired from GFT, contributed an additional $14.5 million.

Our other revenue decreased$3.5 million for the three months ended March 31, 2014, compared to the three months ended March 31, 2013, primarily due to the impact of foreign currency translation.

33

Expenses

	Three Months Ended March 31,
	(amounts in thousands)
	2014			2013
Total expenses	$	74,799		$	44,625
As a percentage of net revenue	93.6		%	89.7		%

Our total expenses for the three months ended March 31, 2014 increased $30.2 million, or 67.6%, compared to the three months ended March 31, 2013. The increase is primarily due to the impact of including GFT's business in our results for the three months ended March 31, 2014. We acquired GFT in September 2013 and its results, therefore, are not included for the three months ended March 31, 2013. The increase in expenses consisted primarily of an increase of $10.5 million in referral fees, an increase of $6.8 million in employee compensation and benefits, an increase of $3.1 million in trading expenses, an increase of $3.6 million in general and administrative expenses, an increase of $2.3 million in acquisition, restructuring and integration expense, an increase of $1.8 million in communications and technology expense and an increase of $0.6 million in depreciation expense.

Employee Compensation and Benefits

	Three Months Ended March 31,
	(amounts in thousands)
	2014			2013
Employee compensation and benefits	$	21,842		$	15,028
As a percentage of net revenue	27.3		%	30.2		%

Employee compensation and benefits expenses increased $6.8 million, or 45.3%, for the three months ended March 31, 2014 compared to the three months ended March 31, 2013. Salaries and benefits (excluding commissions and bonus) increased $4.7 million for the three months ended March 31, 2014, primarily due to the GFT acquisition. Commissions increased $3.0 million during that period, primarily due to our sales trader business, acquired from GFT, as well as increased performance in our GTX business. Bonus expenses decreased $0.9 million due to the results of operations compared to the prior year period.

Referral fees

	Three Months Ended March 31,
	(amounts in thousands)
	2014			2013
Referral fees	$	20,688		$	10,186
As a percentage of net revenue	25.9		%	20.5		%

Referral fees for the three months ended March 31, 2014 increased $10.5 million, or 103.1%, compared to the three months ended March 31, 2013. The increase was the result of greater customer trading volume directed to us by our white label partners and introducing brokers, primarily due to partner relationships acquired as part of the GFT acquisition. Our indirect business accounted for 48.0% of retail trading volume in the three months ended March 31, 2014, as compared to 34.8% for the three months ended March 31, 2013. As a result of our acquisition of GFT, we expect that our indirect business will account for an increased percentage of our retail trading volume in future periods.

Trading expenses for the three months ended March 31, 2014 increased $3.1 million, or 81.7%, compared to the three months ended March 31, 2013. The increase in trading expense consisted primarily of increased exchange fees for our retail business resulting from greater trading volume following the acquisition of GFT. Exchange fees are fees paid to stock exchanges and other third-parties for exchange market data that we provide to our customers or use to create our own derived data products. Clearing and exchange fees associated with our GTX and futures businesses increased $0.5 million for the three months ended March 31, 2014 as compared to the comparable period in 2013.

Liquidity and Capital Resources

We have historically financed our liquidity and capital needs primarily through the use of funds generated from operations, the issuance of debt and equity securities, including the Convertible Senior Notes that we issued in the fourth quarter of 2013, and access to secured lines of credit. We plan to finance our future operating liquidity and regulatory capital needs in a manner consistent with our past practice. We expect that our capital expenditures for the next 12 months will be consistent with our historical annual spend.

We primarily hold and invest our cash at various financial institutions and in various investments, including cash held at banks, deposits at our wholesale forex trading partners and money market funds which invest in short-term U.S. government securities. In general, we believe all of our investments and deposits are of high credit quality and we have adequate liquidity to conduct our businesses.

As a holding company, nearly all of our funds from operations are generated by our operating subsidiaries. Historically, we have accessed these funds through receipt of dividends from these subsidiaries. The following table shows the amount of cash held by our non-U.S. operating subsidiaries and the level of undistributed earnings (amounts in thousands) at March 31, 2014:

Entity Name	Cash		Undistributed Earnings
GAIN Capital-Forex.com U.K., Ltd.	$	429,091	65,281
Forex.com Japan Co., Ltd.	53,938		-

GAIN Global Markets, Inc.	69		-
Island Traders (Cayman) Limited	8		-
Total	$	562,997	$	120,410

At March 31, 2014, as reflected in the table above, we had approximately $116.3 million of undistributed earnings of our foreign subsidiaries indefinitely invested outside the United States. These earnings are expected to be reinvested in the working capital and other business needs of the foreign subsidiaries. No provision has been made for U.S. taxes that would arise if these earnings were repatriated to the United States. If these earnings had been repatriated into the United States as of March 31, 2014, in the form of dividends or otherwise, the Company would have been subject to additional income taxes of approximately $7.4 million.

Some of our operating subsidiaries are subject to requirements of various regulatory bodies, including the CFTC and NFA in the United States, the Financial Conduct Authority in the United Kingdom, the Japan Ministry of Economy, Trade and Industry, the Financial Services Agency and the Japan Ministry of Agriculture, Forestry and Fisheries in Japan, the Securities and Futures Commission in Hong Kong, the Australian Securities and Investments Commission in Australia, and the Cayman Islands Monetary Authority in the Cayman Islands, relating to liquidity and capital standards, which limit funds available for the payment of dividends to GAIN Capital Holdings, Inc. As a result, we may be unable to access funds which are generated by our operating subsidiaries when we need them. In accordance with CFTC regulation 1.12 and NFA Financial Requirements Section 1, a 20.0% decrease in GAIN Capital Group, LLC’s net capital and a 30.0% decrease in excess net capital due to a planned equity withdrawal requires regulatory notification and/or approval.

As compared to amounts reported in our Annual Report on Form 10-K ,filed on March 17, 2014, regulatory requirements decreased approximately $12.5 million, primarily due to reduced capital charges at our UK regulated affiliates.

The following table illustrates the minimum regulatory capital our subsidiaries were required to maintain as of March 31, 2014 and the actual amounts of capital that were maintained on that date (amounts in millions):

Our futures commission merchant and forex dealer subsidiary, GAIN Capital Group, LLC, is subject to the Commodity Futures Trading Commission Net Capital Rule (Rule 1.17) and NFA Financial Requirements. Sections 11 and 12. Under applicable provisions of these regulations, Gain Capital Group, LLC is required to maintain adjusted net capital of the greater of $1.0 million or 8% of Customer and Non-Customer Maintenance Margin, or $20,000,000, plus 5% of all liabilities owed to customers exceeding $10,000,000. Net capital represents current assets less total liabilities as defined by CFTC Rule 1.17. Our current assets primarily consist of cash and cash equivalents reported on our balance sheet as cash, receivables from brokers and trading securities, which are generally short-term U.S. government securities. Our total liabilities include payables to customers, accrued expenses, accounts payable, sales and marketing expense payable, introducing broker fees payable and other liabilities. From net capital we take certain percentage deductions against assets held based on factors required by the Commodity Exchange Act to calculate adjusted net capital. Our net capital and adjusted net capital changes from day to day. As of March 31, 2014, GAIN Capital Group, LLC had net capital of approximately $35.4 million and net capital requirements of $24.7 million. As of March 31, 2014, the excess net capital of GAIN Capital Group, LLC was $10.7 million. We believe that we currently have sufficient capital to satisfy these on-going minimum net capital requirements.

In July 2010, Congress passed the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act. A number of significant provisions contained 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 derivatives in which we engage. The Dodd-Frank Act requires the registration of swap dealers with the CFTC and imposes significant regulatory requirements on swap dealers. Effective February 27, 2013, GAIN GTX, LLC, became registered with the CFTC and NFA as a swap dealer. Certain of our other subsidiaries may be required to register, or may register voluntarily, as swap dealers. Swap dealers are subject to a comprehensive regulatory regime with new obligations for the swaps activities for which they are registered, including adherence to risk management policies, supervisory procedures, trade record and real time reporting requirements as well as proposed rules for new minimum capital requirements. The specific parameters of these swap dealer requirements are being developed by the CFTC and other regulators. The full impact of the regulation on GAIN GTX and any other of our subsidiaries that register as a swap dealer remains unclear. It is likely, however, that these entities will face increased costs due to the registration and regulatory requirements listed above. Complying with the proposed regulation of swap dealers could require us to restructure our businesses, require extensive systems changes, require personnel changes or raise additional potential liabilities and regulatory oversight. Compliance with swap-related regulatory capital requirements may require us to devote more capital to our GTX business. The increased costs associated with compliance, and the changes that will be required in our OTC and clearing businesses, may adversely impact our results of operations, cash flows, or financial condition.

We are required to maintain cash on deposit with our wholesale forex trading partners in order to conduct our hedging activities. As of March 31, 2014, we posted $211.4 million in cash with wholesale forex trading partners, of which $123.4 million was required as collateral pursuant to our agreements for holding securities positions with such institutions, with $85.3 million representing the available cash in excess of required collateral. As of March 31, 2014, total client assets were $801.0

38

million. Total client assets represent amounts due to clients, including deposits and unrealized gains or losses arising from our clients’ open positions.

The table set forth below provides information regarding our total available liquidity as of March 31, 2014 and as of December 31, 2013. We use this non-GAAP measure to evaluate our business operations and our ability to continue to grow through acquisitions (amounts in millions):

	As of March 31, 2014			As of December 31, 2013
Cash & cash equivalents	$	44.9		$	39.9

(1) Reflects cash that would be received upon the liquidation of short term investments. We estimate that all short term investments as of the date indicated could be liquidated within one to two business days.

(2) Reflects cash that would be received from brokers following the close-out of all open positions. We estimate that liquidation of all open positions as of the date indicated could be completed within one to two business days.

(3) The note payable amount reflects the aggregate principal amount of the notes outstanding, rather than solely the debt portion that is carried on our consolidated balance sheets at March 31, 2014.

(4) Does not reflect reduction for current liabilities of $70.5 million and $72.1 million at March 31, 2014 and December 31, 2013, respectively.

Convertible Senior Notes

On November 27, 2013, we issued $80 million aggregate principal amount of our 4.125% Convertible Senior Notes due 2018 in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The net proceeds from the note offering were approximately $77.2 million, after deducting discounts and commissions to the initial purchasers and estimated offering expenses payable by the company.

The notes bear interest at a fixed rate of 4.125% per year, payable semiannually in arrears on June 1 and December 1 of each year, beginning on June 1, 2014. The semi-annual interest payment on the notes will equal approximately $1.7 million for June and December 2014. The notes are convertible into cash, shares of our common stock, or a combination thereof, at our election, subject to certain limitations. The notes will mature on December 1, 2018, unless earlier converted, redeemed or repurchased. We may not redeem the notes prior to December 1, 2016.

In May 2008, the Financial Accounting Standards Board, or FASB, issued FASB Staff Position No. APB 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement), which has subsequently been codified as Accounting Standards Codification 470-20, Debt with Conversion and Other Options, or ASC 470-20. ASC 470-20 requires an entity to separately account for 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) in a manner that reflects 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 debt instrument that does not have an associated equity component and was reflected as a liability in our consolidated balance sheet in an amount equal to the fair value, which, as of March 31, 2014, was $67.4 million. The equity component of the notes is included in the additional paid-in capital section of our stockholders’ equity on our consolidated balance sheet, and the value of the equity component is treated as original issue discount for purposes of accounting for the debt component. The equity component, as of March 31, 2014, was $12.6 million. This original issue discount is amortized to non-cash interest expense over the term of the notes, and, as a result, we record a greater amount of non-cash interest expense in current periods. Accordingly, we will report lower net income in our financial results than would have been recorded had we reflected only cash interest expense in our consolidated income statement because ASC 470-20 will

39

require the interest expense associated with the notes to include both the current period’s amortization of the debt discount and the notes’ coupon interest, which could adversely affect our reported or future financial results, the trading 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) are currently accounted for using the treasury stock method. Under this method, the shares issuable upon conversion of the notes are not included in the calculation of diluted earnings per share unless the conversion value of the notes exceeds their principal amount at the end of the relevant reporting period. If the conversion value exceeds their 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 be necessary 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 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.

Cash Flow

The following table sets forth a summary of our cash flow for the three months ended March 31, 2014 and the three months ended March 31, 2013 (amounts in thousands):

	For the Three Months Ended March 31,
	2014			2013
Cash provided by/(used for) operating activities	$	15,009		$	(32,232	)
Cash used for investing activities	(9,602		)	(1,040		)
Cash (used for)/provided by financing activities	(853		)	7,958
Effect of exchange rate changes on cash and cash equivalents	465			556
Increase/(Decrease) in cash and cash equivalents	$	5,019		$	(24,758	)

The primary drivers of our cash flow provided by operating activities are net income, amounts posted as collateral with wholesale forex trading partners and amounts paid to fund our operations.

Amounts posted as collateral with wholesale foreign exchange trading partners are classified on our balance sheet as receivables from brokers and represent collateral required to be deposited with our wholesale forex trading partners in order for us to hold spot foreign exchange positions, as well as the cash posted with wholesale forex trading partners in excess of required collateral. We post cash with wholesale forex trading partners in excess of required collateral to allow for adverse currency price moves relative to our positions, which would raise our level of required collateral. We receive interest on amounts we have posted as collateral with wholesale forex trading partners. The amount of collateral required by our wholesale forex trading partners in the future will be commensurate with the amount of spot foreign exchange positions that they hold on our behalf. The amount of cash posted with wholesale forex trading partners in excess of required collateral is discretionary and may increase or decrease in future periods as we determine the most efficient uses of our cash.

Our largest operating expenses are employee compensation and benefits and referral fees. Employee compensation and benefits include salaries, bonuses and other employee related costs. Referral fees consist primarily of compensation paid to our white label partners and introducing brokers.

Unrealized gains and losses on cash positions revalued at prevailing foreign currency exchange rates are included in trading revenue but have no direct impact on cash flow from operations. Gains and losses become realized and impact cash flow from operations when customer transactions are liquidated. To some extent, our net deposit activity is influenced by unrealized gains and losses because our customers’ trading positions are impacted by unrealized gains and losses and our customers may be required to post additional funds to maintain open positions or may choose to withdraw excess funds on open positions.

Cash provided by operating activities was $15.0 million for the three months ended March 31, 2014, compared to cash used by operating activities of$32.2 million for the three months ended March 31, 2013. The primary reason for the increase in cash provided by operating activities was a decrease in receivables from bank and brokers of $16.8 million, offset by decreases of $6.7 million in accrued compensation and benefits, as well as $5.6 million in other assets.

Cash used for investing activities was $9.6 million for the three months ended March 31, 2014, compared to cash used by investing activities of$1.0 million for the three months ended March 31, 2013. The increase in cash used was primarily a result of $4.3 million used to purchase GAA and $3.2 million used to purchase TT.

40

Cash used by financing activities was $0.9 million for the three months ended March 31, 2014, compared to cash provided by financing activities of$8.0 million for the three months ended March 31, 2013. The decrease in cash provided by financing activities results from a $10.0 million drawdown on our revolving credit line in 2013.

Capital Expenditures

Capital expenditures were $3.2 million for the three months ended March 31, 2014, compared to $1.0 million for the three months ended March 31, 2013. Capital expenditures for both periods primarily related to the development of our trading platforms and websites.

Contractual Obligations

For the three months ended March 31, 2014, there were no significant changes to our vendor or operating lease obligations from those disclosed in the section “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2013.

Off-Balance-Sheet Arrangements

At March 31, 2014 and December 31, 2013, we did not have any off-balance-sheet arrangements.

Critical Accounting Policies and Estimates

Our Unaudited Condensed Consolidated Financial Statements and accompanying notes have been prepared in accordance with GAAP applied on a consistent basis. The preparation of these financial statements requires us to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the periods presented. We evaluate these estimates and assumptions on an ongoing basis. We base our estimates on the information currently available to us and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, if different estimates reasonably could have been used, or if changes in the estimate that are reasonably likely to occur periodically could materially impact the financial statements. While our significant accounting policies are described in more detail in the notes to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2012, we believe the following accounting policies to be critical to the estimates and assumptions used in the preparation of our Unaudited Condensed Consolidated Financial Statements.

Revenue Recognition

Revenue is recognized at trade-date.

Retail revenue is determined by the change in the price of the underlying. Unrealized gains or losses on positions revalued at prevailing rates (the difference between contract price and market price) at the date of the balance sheet are included in Receivables from brokers and Payables to customers,brokers, dealers, FCMs and other regulated entities on the Consolidated Balance Sheet. Changes in net unrealized gains or losses are recorded in Trading revenue on the Unaudited Consolidated Statements of Operations and Comprehensive Income.

Commission revenue is determined by the volume of trades. Commission revenue is derived from our GTX business, our futures business and our sales trader business.

Income Taxes

Current income tax is calculated on the basis of the tax laws enacted or substantially enacted at the year end in the countries where we operate and generate taxable income.

Deferred income tax expenses are determined using the asset and liability method, under which deferred tax assets and liabilities are determined based upon the temporary differences between the consolidated financial statements and the income tax basis, using currently enacted tax rates. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in our Consolidated Statements of Operations and Comprehensive Income in the period of enactment. We routinely evaluate all deferred tax assets to determine the likelihood of their realization.

41

We use estimates in determining income tax positions under ASC 740-10-25, Income Taxes. Although we believe that our tax estimates are reasonable, the ultimate tax determination involves significant judgment and is subject to audit by tax authorities in the ordinary course of business.

To the extent we are required to pay amounts in excess of our reserves, our effective income tax rate in a given financial statement period could be materially affected. An unfavorable tax settlement could require use of our cash and result in an increase in our effective income tax rate in the period of resolution.

We operate a permanent reinvestment strategy, under which earnings derived from foreign business remain invested in the Company’s foreign subsidiaries. We have no plans to repatriate these earnings.

Impairment of Long-Lived Assets

In accordance with ASC 360-10, Property, Plant and Equipment, we periodically evaluate the carrying value of long-lived assets when events and circumstances warrant such review. The carrying value of a long-lived asset is considered impaired when the anticipated undiscounted cash flow from such an asset is separately identifiable and is less than the carrying value. In that event, a loss is recognized in the amount by which the carrying value exceeds the fair market value of the long-lived asset.

Convertible Senior Notes

In November 2013, we issued $80 million aggregate principal amount of our 4.125% Convertible Senior Notes due 2018. These notes are hybrid instruments, having both a debt and an equity component, and we accounted for them in accordance with relevant guidance for such instruments. The debt component includes an initial discount determined by the notes' coupon rate and prevailing market interest rates. The equity component equals the initial discount and is included in Additional Paid in Capital. The discount will amortize over the life of the notes, as we record interest expense. The notes will mature on December 1, 2018, unless earlier converted redeemed or repurchased.

Business Combinations

In March 2014, we completed our acquisition of GAA and TT. We accounted for these transactions in accordance with accounting guidance for business combinations, which required identifying the acquirer, determining the acquisition date, determining the purchase price and determining fair values for assets and liabilities assumed, as well as calculating goodwill. We disclosed acquisition, restructuring, and integration expenses separately. Please see "Note 5 - Acquisitions" to our audited consolidated financial statements for more information.

Goodwill and Intangible Assets

ASC 350-30, General Intangibles, requires a purchased intangible asset other than goodwill to be amortized over its useful life unless the useful life is determined to be indefinite. If the asset is determined to have a finite life in the future, we will amortize the carrying value over the remaining useful life at that time. In accordance with ASC 350-30, our URLs (foreignexchange.com and forex.com) are indefinite life intangible assets and are, therefore, not amortized. We compare the recorded value of the indefinite life intangible assets and goodwill to their fair value on an annual basis and whenever circumstances arise that indicate that impairment may have occurred.

Accrued Compensation

We make estimates in determining our quarterly and annual accrued non-share-based compensation. A significant portion of our employee incentive compensation programs are discretionary. Each quarter and year-end we determine the amount of discretionary cash bonus pools. We also review compensation throughout the year to determine how overall performance compares to management’s expectations. We take these and other factors, including historical performance and our performance relative to budget, into account in reviewing accrued discretionary cash compensation estimates quarterly and adjusting accrual rates as appropriate. Changes to these factors could cause a material increase or decrease in the amount of compensation expense that we report in a particular period.

Derivatives

Forex, metals and CFDs allow for the exchange of the difference in value of a particular asset such as a stock index, energy product, or gold contracts, between the time at which a contract is opened and the time at which it is closed. Our open positions

42

and those of our retail customer are considered derivatives under FASB ASC 815. Therefore, they are accounted for at fair value and are included in Receivables from banks and brokers and Payables to customers, brokers, dealers, FCMs and other regulated entities in the consolidated balance sheets.

Share Based Payments

ASC 718-10, Compensation – Stock Compensation, requires measurement of share based payment arrangements at fair value and recognition of compensation cost over the service period, net of estimated forfeitures. The fair value of restricted stock units is determined based on the number of units granted and the grant date fair value of GAIN Capital Holding, Inc.’s common stock.

We measure the fair value of stock options on the date of grant using the Black-Scholes option pricing model which requires the use of several estimates, including:

• The volatility of our stock price;

• The expected life of the option;

• Risk free interest rates; and

• Expected dividend yield.

The use of different assumptions in the Black-Scholes pricing model would result in different amounts of stock-based compensation expense. Furthermore, if different assumptions are used in future periods, stock-based compensation expense could be materially impacted in the future.

The expected volatility was calculated based upon the volatility of public financial services companies, or companies in similar industries. The average risk free rate is based upon the five year bond rate converted to a continuously compounded interest rate.

ITEM 4. CONTROLS AND PROCEDURES

In connection with the Original Filing, management of the Company, with the participation of its chief executive officer and chief financial officer, evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of March 31, 2014 and concluded that the disclosure controls and procedures were effective. In connection with the restatement of the Company’s unaudited condensed consolidated financial statements for the quarter ended March 31, 2014, which is discussed in Note 14 to the Company’s unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q/A, management of the Company, with the participation of its chief executive officer and chief financial officer, has re-evaluated the effectiveness of the Company’s disclosure controls and procedures as of March 31, 2014. Based on that re-evaluation, and in light of the material weakness in internal control over financial reporting described below, the chief executive officer and the chief financial officer have concluded that, as of March 31, 2014, the Company’s disclosure controls and procedures were not effective to ensure that information the Company is required to disclose in reports that the Company files or submits under the Exchange Act is recorded, processed, summarized, or reported, within the time periods specified in rules and forms of the SEC, and is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosures.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. In light of the need to restate the Company’s unaudited condensed consolidated financial statements, management of the Company has concluded that a material weakness in internal control over financial reporting existed as of March 31, 2014. Management of the Company has identified the material weakness as resulting from human error in the booking of certain revenue and expense items following the combination of the operations of the Company's subsidiaries in the United Kingdom that was not prevented by the Company's risk assessment procedures and manual controls at the time of the combination. In addition, although a monitoring control ultimately assisted the Company in identifying that the booking of such items had not occurred, as a result of human error, the matter was not addressed prior to the date of the Original Filing.

Remediation Plan

Since identifying the material weakness in our internal control over financial reporting discussed above, the Company’s management has implemented an automated process to replace and/or supplement the manual process previously relied upon. In addition, the monitoring internal control process will be expanded and the frequency adjusted to take effect monthly. The Company is also reviewing resource requirements and capabilities in its UK finance team to determine whether roles and responsibilities need to be realigned or new personnel added. The management of the Company is continuing to review these matters to ensure that similar failures of internal control over financial reporting do not recur.

Accounting Changes and Error Corrections [Abstract]

RECENT ACCOUNTING PRONOUNCEMENTS

RECENT ACCOUNTING PRONOUNCEMENTS

In July 2013, the Financial Accounting Standards Board, ("FASB") issued Accounting Standards Update (“ASU”) No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU 2013-11 requires presenting unrecognized tax benefits netted against deferred tax assets, if such assets are sufficient and expected to replace cash payment, should an uncertain tax position not be sustained. This update is currently in effect. The Company has applied this update in 2014. The Company believes that it does not materially affect the three months ending March 31, 2014.

DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Description of Business

GAIN Capital Holdings, Inc., together with its subsidiaries (the “Company”), is a Delaware corporation formed and incorporated on March 24, 2006. GAIN Holdings, LLC is a wholly-owned subsidiary of GAIN Capital Holdings, Inc., and owns all outstanding membership units in GAIN Capital Group, LLC (“Group, LLC”), the primary regulated entity in the United States of America.

Group, LLC is a retail foreign exchange dealer (“RFED”) and a registered Futures Commission Merchant (“FCM”) with the Commodity Futures Trading Commission (“CFTC”). As such, it is subject to the regulations of the CFTC, an agency of the U.S. Government, and the rules of the National Futures Association (“NFA”), an industry self-regulatory organization.

The following list includes each of the Company’s significant U.S. and international regulated subsidiaries:

GAIN Capital Group, LLC

GAIN Capital-Forex.com U.K., Ltd.

Forex.com Japan Co., Ltd.

GAIN Capital Forex.com Australia Pty. Ltd.

GAIN Capital-Forex.com Hong Kong Ltd.

GAIN Capital-Forex.com Canada, Ltd.

GAIN GTX, LLC

GAIN GTX SEF, LLC

Global Futures & Forex, Ltd.

GFT Global Markets UK Ltd.

GFT Global Markets Asia Pte., Ltd.

In March 2014, the Company acquired controlling interests in Global Asset Advisors, LLC ("GAA") and Top Third Ag Marketing LLC ("TT").

In September 2013, the Company purchased all of the outstanding share capital of Global Futures & Forex, Ltd., a Michigan corporation ("GFT").

See note 5 "Acquisitions" for further details related to these acquisitions.

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements reflect all adjustments, all of which are normal recurring adjustments that, in the opinion of management, are necessary for a fair presentation of the financial statements for the interim periods. The unaudited condensed consolidated financial statements have been prepared in accordance with the regulations of the Securities and Exchange Commission ("SEC") for interim financial statements, and, in accordance with SEC rules, omit or condense certain information and footnote disclosures. Results for the interim periods are not necessarily indicative of results to be expected for any other interim period or for the full year. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 filed with the SEC on March 17, 2014 (the “2013 Form 10-K”). There have been no changes in the significant accounting policies from those included in the 2013 Form 10-K. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, after the elimination of inter-company transactions and balances.

In an effort to align the presentation of expenses with competitors in the industry in order to enable easier comparisons, the Company has presented commissions paid to employees, previously presented in "Trading expenses and commissions" under "Employee compensation and benefits." Additionally, the Company has presented compensation paid to its white label partners and introducing brokers, which was also previously presented in "Trading expenses and commissions," under the new caption of "Referral fees." The remaining items that were previously presented in "Trading expenses and commissions," including exchange fees, fees for news services and prime broker fees, are now presented under a new caption, "Trading expenses." These changes in presentation had no effect on the total expenses.

Commitments and Contingencies Disclosure [Abstract]

LEGAL

LEGAL

From time to time the Company becomes involved in legal proceedings and in each case the Company assesses the likely liability and/or the amount of damages as appropriate. Where available information indicates that it is probable a liability had been incurred at the date of the condensed consolidated financial statements and the Company can reasonably estimate the amount of that loss, the Company accrues the estimated loss by a charge to income. In many proceedings, however, it is inherently difficult to determine whether any loss is probable or even possible or to estimate the amount of any loss. In addition, even where loss is possible or an exposure to loss exists in excess of the liability already accrued with respect to a previously recognized loss contingency, 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 amounts accrued. For certain other legal proceedings, the Company cannot reasonably estimate such losses, if any, since the Company cannot predict if, how or when such proceedings will be resolved or what the eventual settlement, fine, penalty or other relief, if any, may be, particularly for proceedings that are in their early stages of development or where plaintiffs seek substantial or indeterminate damages. Numerous issues must be developed, including the need to discover and determine important factual matters and the need to address novel or unsettled legal questions relevant to the proceedings in question, before a loss or additional loss or range of loss or additional loss can be reasonably estimated for any proceeding.

Litigation

On 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 a third-party money management firm, incorporated in the United Kingdom, which has since been closed down by the United Kingdom’s Financial Services Authority. The investment firm, Cameron Farley Ltd, had opened a corporate account with the Company and invested the individuals’ money, representing such funds as its own, while operating a fraudulent scheme. Though a complaint has been filed and served on the Company, the claimants requested, and the Company agreed, to follow the United Kingdom’s Pre-Action Protocol, a pre-litigation process intended to resolve matters without the need to engage in formal litigation. The Company submitted a Response to the Letter before Claim on July 4, 2012. On July 5, 2012 the Company received a substantially similar Letter of Claim on behalf of further individuals. Subsequently, the parties agreed to consolidate claims by those other similarly situated individuals with the pending Pre-Action Protocol process. The parties agreed it would be more appropriate for the proceedings to be dealt with in the Commercial Court and the matters were transferred pursuant to Consent Orders dated March 14, 2013. The Company subsequently filed an application for strike out and/or summary judgment in respect of all claims on March 15, 2013. The claimants filed an answer to the Company's motion on June 2, 2013 and subsequently the Company filed a response to this answer on July 15, 2013. A hearing was held on the Company's application for strike out and/or summary judgment on September 18 and 19, 2013.  After the hearing, the judge asked the claimants to respond in writing to his additional questions from the hearing.  The complaints had until October 11, 2013 to provide answers and the Company was given until November 1, 2013 to respond.  On February 26, 2014, the judge denied the Company's motion for strike out/ summary judgment. The Company can provide no assurances that this matter will be successfully resolved. This matter is currently pending. As of the date of this report, a potential loss or a potential range of loss cannot be reasonably estimated.

Through the Company's acquisition of OEC, the Company became the subject of a patent infringement lawsuit originally filed against OEC on February 9, 2010 in the U.S. District Court for the Northern District of Illinois by Trading Technologies International, Inc. seeking injunctive relief and unspecified damages. As reflected in a Second Amended Complaint filed on June 15, 2011, plaintiff alleges infringement of 12 patents relating to real-time display of price quotes and market depth on OEC's electronic trading interfaces. The case was consolidated with 11 related cases in February 2011, and the parties have exchanged infringement, non-infringement and invalidity contentions for several of the disputed patents. In June 2011, the court stayed discovery to allow summary judgment briefing on the ramifications of a recent Federal Circuit decision. On February 9, 2012, the court issued an order, which granted defendants' motions for summary judgment, resulting in a substantial narrowing of the scope of plaintiff's claims. Plaintiff filed a motion for reconsideration of that ruling on March 8, 2012. Plaintiff also filed a motion for certification of judgment for interlocutory appeal. The court denied plaintiff's motion for reconsideration but granted plaintiff's motion for certification of judgments of patent invalidity with respect to four of the asserted patents. On August 30, 2013, the Federal Circuit issued its opinion vacating and remanding the court's judgment of patent invalidity regarding four of the asserted patents. On remand, defendants renewed their motion for summary judgment of patent invalidity. In April 2014, the court deferred its consideration of defendants' renewed motion for summary judgment and signaled its intent to re-start the litigation by requesting that the parties submit a proposed pre-trial schedule. Plaintiff's complaint does not specify the amount of damages sought. As of the date of this report, a potential loss or a potential range of loss cannot be reasonably estimated.

INCOME TAXES

INCOME TAXES

The Company’s provision for income taxes was approximately $1.3 million and $0.9 million for the three months ended March 31, 2014 and the three months ended March 31, 2013, respectively. The 2014 amount has been adjusted from the originally filed amount to properly account for amendments to the Company's condensed consolidated statement of operations. These amounts reflect effective tax rates of 24.8% and 16.9%, respectively. The Company's effective tax rate of 24.8% for the three months ended March 31, 2014 reflects the Company's estimate of the annual effective tax rate adjusted for certain discrete items. For the three months ended March 31, 2014 there was a $0.6 million reduction in the provision for income taxes resulting from the conclusion of a NJ State tax audit.

Deferred income taxes reflect the net tax effects of temporary differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when such differences are expected to reverse. The Company’s net deferred tax assets are included in Other assets on the Condensed Consolidated Balance Sheet.

SHARE BASED COMPENSATION

During the three months ended March 31, 2014, 0.4 million shares of restricted stock and approximately 0.1 million options to purchase common stock, valued at $3.7 million and $0.4 million, respectively, were granted to employees and non-employee members of the Board of Directors, compared to 0.8 million shares of restricted stock and 0.3 million options to purchase common stock, valued at $3.6 million and $0.6 million, respectively during the three months ended March 31, 2013.

The Company determines the fair value of restricted stock units and awards at the date of grant based on the value of the Company’s common stock. The Company determines the fair value of our stock option awards at the date of grant using a Black-Scholes valuation model. This model requires assumptions and judgments on the expected volatility, dividend yield, the risk-free interest rate and the expected term of the stock options. The following assumptions were used for stock options granted in the period:

	For the Three Months Ended March 31,

Noncontrolling Interest [Abstract]

Non-Controlling Interest

NON-CONTROLLING INTEREST

Non-controlling interests

In March 2014, the Company acquired controlling interests in GAA and TT. The Company purchased 55% of each entity, and the respective sellers maintained a 45% interest in each entity. The 45% interests are redeemable at prices determined by applying a contractually agreed upon formula to the respective acquired company's financial results. The Company owns immediately vested call options to purchase the remaining interests in each company. The minority owners hold put options, which vest in 2017 or upon the occurrence of certain events, to compel the Company to purchase the remaining interests.

The non-controlling interests are not classified as liabilities, because redemption is not mandatory or at fixed prices. They are not classified as equity, because their redemption is not exclusively in the Company's control. Therefore, the non-controlling interests are held in temporary equity in the Condensed Consolidated Balance Sheets.

The non-controlling interests' carrying value is determined by the Company's purchase prices and the non-controlling interests' share of the Company's subsequent 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 prices allocation. The Company has made a policy election to reflect any changes caused by such an adjustment in retained earnings, rather than in current earnings. The Company recorded no such adjustment for the three months endedMarch 31, 2014.

The table below reflects the non-controlling interests effects on the Company's financial statements:

Non-controlling interests related to 2014 acquisitions	8,395

Earnings Per Share [Abstract]

EARNINGS PER COMMON SHARE

EARNINGS PER COMMON SHARE

Basic and diluted earnings per common share are computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share includes the determinants of basic net income per share and, in addition, gives effect to the potential dilution that would occur if securities or other contracts to issue common stock were exercised, vested or converted into common stock, unless they are anti-dilutive. Diluted weighted average common shares include vested and unvested stock options, vested restricted stock units which are to be delivered as soon as administratively practicable on or after December 31, 2014, unvested restricted stock units and unvested restricted stock awards. Approximately 1.1 million and 0.6 million stock options were excluded from the calculation of diluted earnings per share for the three months ended March 31, 2014 and the three months ended March 31, 2013, respectively, as they were anti-dilutive.

The following table sets forth the computation of earnings per share (amounts in thousands except share and per share data):

	For the Three Months Ended March 31,

Accounting Changes and Error Corrections [Abstract]

RESTATEMENT

RESTATEMENT

Subsequent to the date of the Original Filing, the Company concluded that it was required to restate its unaudited interim condensed consolidated financial statements as of and for the quarter ended March 31, 2014 to make the following changes to the Original Filing:

• Trading activity from some of the Company's omnibus partners that took place on March 31, 2014 was incorrectly recorded on April 1, 2014. Such trading activity should have been included in the first quarter's results, because the revenue was earned and realizable as of March 31, 2014. As a result of this omission, the Company understated its trading revenue for the first quarter of 2014 by $4.2 million.

• Expenses are recorded when goods are received or services performed; this is often in advance of payment, resulting in the recording of a corresponding liability. The Company operates a payment process that automatically results in an expense being recorded when cash is paid. To prevent double counting of expenses the original liability is released at that time. On March 31, 2014, the Company incorrectly assumed a payment to a partner had taken place for services performed in the first quarter of 2014 and therefore incorrectly released the related liability. The payment was actually made on April 1, 2014. As a result, the Company understated referral fees and the related accrual in the first quarter of 2014 by $1.0 million.

• The Company provides its customers market data received from various exchanges and uses the data to derive prices for certain of its products. The Company pays various fees to these exchanges based on the use of market data by the Company and, in some cases, its customers. These fees are based on a number of factors. In estimating these expenses for the first quarter of 2014, the Company did not utilize all relevant information available at the time and, as a result, understated its trading expenses and the related accrual by $0.6 million.

• The Company incorrectly recorded depreciation on an asset that was under construction and not yet in service. As a result, the Company overstated its depreciation expense in the first quarter of 2014 by $0.5 million.

The previously filed unaudited interim condensed consolidated financial statements for the quarter ended March 31, 2014 have been restated to reflect the changes described above and their applicable income tax effects. The following tables reflect the financial statement line items impacted, together with the adjusted amounts. For the avoidance of doubt, the following tables include only those line items impacted by the restatement:

The Company has not changed its valuation techniques in measuring the fair value of any financial assets and liabilities during the period.

Level 1 Financial Assets

The Company has money market accounts, certificates of deposit, CIBC treasury bills and an investment in gold that are Level 1 financial instruments that are recorded based upon listed or quoted market rates. The money market accounts are recorded in Cash and cash equivalents and Cash and securities held for customers, the treasury bills are recorded in Cash and cash equivalents and Short term investments, based upon their maturity, the certificates of deposit are recorded in Short term investments and the investment in gold is recorded in Receivables from banks and brokers.

Level 2 Financial Assets and Liabilities

The Company has open contracts and other positions that are Level 2 financial instruments that are recorded in Receivables from banks and brokers.

The Company has customer and broker open contracts and other positions that are Level 2 financial instruments that are recorded in Payable to customers, brokers, dealers, FCMs and other regulated entities.

These Level 2 financial instruments are based upon directly observable values for underlying instruments.

Financial Instruments Not Measured at Fair Value

The table below presents the carrying value, fair value, and fair value hierarchy category of certain financial instruments that are not measured at fair value in the Condensed Consolidated Balance Sheet (amounts in thousands). The carrying value of Receivables from banks and brokers not measured at fair value approximates fair value because of the relatively short period of time between their origination and expected maturity. The carrying value of Payables to customers, brokers, dealers, FCMs, and other regulated entities includes amounts deposited by these customers and financial institutions in order for the Company to act as a clearing broker. The carrying value of Payables to customers, brokers, dealers, FCMs, and other regulated entities includes cash and open positions. The carrying value of Convertible senior notes represents the notes’ principal amounts net of unamortized discount (see note 7). We assessed the notes' fair value against prevailing interest rates as of the balance sheet date. The carrying value of Accrued expense and other liabilities includes $20.0 million, referred to as the Holdback Amount, to be paid net of an amount required to settle certain liabilities of GFT after the closing date of the acquisition (see note 5). The carrying values of Accrued expense and other liabilities not measured at fair value approximate fair value because of the relatively short period of time between their origination and expected settlement date.

1. Fully amortized intangible assets have been removed from both the cost and accumulated amortization columns at March 31, 2014.

As mentioned in Note 1 above, in March 2014, the Company purchased controlling interests in GAA and TT; in September 2013, the Company purchased all of the outstanding share capital of GFT.

The preliminary purchase price allocations to intangible assets are detailed below in Note 5, “Acquisition”.

In 2003, the Company acquired the Forex.com domain name for $0.2 million, and in 2004, the foreignexchange.com domain name was purchased for $0.1 million. Because the rights to use these domain names require the payment of a nominal annual renewal fee, management determined that there was no legal, regulatory or technological limitation on their useful lives. Accordingly, these indefinite-lived assets are not amortized. In accordance with ASC 350-10, the Company tests intangible assets for impairment on an annual basis in the fourth quarter and on an interim basis when conditions indicate impairment may have occurred.

Amortization expense for the purchased intangibles was $1.0 million and $0.6 million for the three months ended March 31, 2014 and 2013, respectively.

Goodwill

Goodwill is calculated as the difference between the cost of acquisition and the fair value     of the net identifiable assets of an acquired business. As of March 31, 2014 and December 31, 2013, the Company had recorded goodwill of approximately $26.1 million and $14.2, respectively.

Goodwill increased $5.5 million as a result of the GAA acquisition, $4.7 million as a result of the TT acquisition, and $6.2 million as a result of the GFT acquisition. The $6.2 million arising from the GFT acquisition was adjusted from the amount reported at December 31, 2013, as part of preliminary purchase accounting.

Other Assets

Other assets consisted of the following as of (amounts in thousands):

	March 31, 2014		December 31, 2013
Vendor and security deposits	$	3,765	$	3,344
Current tax receivable	8,354		4,547
Deferred tax assets	6,342		4,922
Investment in Kapitall, Inc.	50		50
Indemnification asset	8,596		8,596
GTX Trade Receivables	5,803		4,704
Miscellaneous receivables	2,913		2,446
	$	35,823	$	28,609

The Company has recorded a liability of $5.4 million in Accrued expenses and other liabilities. This represents the Company's best estimate for the settlement of certain liabilities that were incurred as a result of ordinary course of operations in GFT prior to its acquisition. $3.2 million of these liabilities have been settled between acquisition date and March 31, 2014. The actual amount required to settle the remaining liabilities may vary from this estimate.

Under the terms of the acquisition of GFT, the selling stockholder of GFT has agreed to indemnify the Company for these liabilities that are expected to be settled after September 24, 2013. Based on the Company's best estimate of the amounts necessary to settle such liabilities, the Company recorded an indemnification asset of $8.6 million at March 31, 2014. This is included within Other current assets in the preliminary purchase price allocation of GFT, refer to note 5.

Segment Reporting [Abstract]

SEGMENT INFORMATION

SEGMENT INFORMATION

ASC 280, Disclosures about Segments of an Enterprise and Related Information, establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-maker, or decision making group, in deciding how to allocate resources and in assessing performance. Reportable segments are defined as an operating segment that either (a) exceeds 10% of revenue, or (b) reported profit or loss in absolute amount exceeds 10% of profit of all operating segments that did not report a loss or (c) exceeds 10% of the combined assets of all operating segments. The Company’s operations relate to global trading services and solutions. Based on the Company’s management strategies, and common production, marketing, development and client coverage teams, the Company has concluded that it operates in a single operating segment.
