INTRODUCTORY NOTE

The financial statements and other disclosures contained in this report include those of Tradeweb Markets Inc., which is the registrant, and those of its consolidating subsidiaries, including Tradeweb Markets LLC, which became the principal operating subsidiary of Tradeweb Markets Inc. on April 4, 2019 in a series of reorganization transactions (the “Reorganization Transactions”) that were completed in connection with Tradeweb Markets Inc.’s initial public offering (the “IPO”), which closed on April 8, 2019. For more information regarding the transactions described above, see Note 1—Organization to our unaudited consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

The financial statements and other disclosures contained in this Quarterly Report on Form 10-Q relate to periods that ended both prior to and after the completion of the Reorganization Transactions and the IPO. As a result of the Reorganization Transactions completed in connection with the IPO, Tradeweb Markets Inc. became a holding company whose only material assets consist of its equity interest in Tradeweb Markets LLC and related deferred tax assets. As the sole manager of Tradeweb Markets LLC, Tradeweb Markets Inc. operates and controls all of the business and affairs of Tradeweb Markets LLC and, through Tradeweb Markets LLC and its subsidiaries, conducts its business. As a result of this control, and because Tradeweb Markets Inc. has a substantial financial interest in Tradeweb Markets LLC, Tradeweb Markets Inc. consolidates the financial results of Tradeweb Markets LLC and its subsidiaries.

The unaudited consolidated financial statements and other financial disclosures included elsewhere in this Quarterly Report on Form 10-Q relating to periods prior to and including March 31, 2019, which we sometimes refer to as the “pre-IPO period,” reflect the results of operations, financial position and cash flows of Tradeweb Markets LLC, the predecessor of Tradeweb Markets Inc. for financial reporting purposes, and its subsidiaries. The unaudited consolidated financial statements and other financial disclosures included elsewhere in this Quarterly Report on Form 10-Q relating to periods beginning on April 1, 2019, and through and including September 30, 2019, which we sometimes refer to as the “post-IPO period,” reflect the results of operations, financial position and cash flows of Tradeweb Markets Inc. and its subsidiaries, including the consolidation of its investment in Tradeweb Markets LLC. As a result, for financial reporting purposes, the pre-IPO period excludes, and the post-IPO period includes, our financial results from April 1, 2019 through April 3, 2019, which are not material. The unaudited consolidated financial statements and other financial disclosures included elsewhere in this Quarterly Report on Form 10-Q do not reflect what the results of operations, financial position or cash flows would have been had the Reorganization Transactions and the IPO taken place at the beginning of the periods presented.

As used in this Quarterly Report on Form 10-Q, unless the context otherwise requires, references to:

“We,” “us,” “our,” the “Company,” “Tradeweb” and similar references refer: (i) on or prior to the completion of the Reorganization Transactions to Tradeweb Markets LLC, which we refer to as “TWM LLC,” and, unless otherwise stated or the context otherwise requires, all of its subsidiaries and any predecessor entities, and (ii) following the completion of the Reorganization Transactions to Tradeweb Markets Inc., and, unless otherwise stated or the context otherwise requires, TWM LLC and all of its subsidiaries and any predecessor entities.

“Continuing LLC Owners” refer collectively to (i) those Original LLC Owners, including an indirect subsidiary of Refinitiv (as defined below), certain of the Bank Stockholders and members of management, that continue to own LLC Interests after the completion of the IPO and Reorganization Transactions, that received shares of our Class C common stock, shares of our Class D common stock or a combination of both, as the case may be, in

3

connection with the completion of the Reorganization Transactions, and that may redeem or exchange their LLC Interests for shares of our Class A common stock or Class B common stock and (ii) solely with respect to the Tax Receivable Agreement (as defined below), also includes those Original LLC Owners, including certain Bank Stockholders, that disposed of all of their LLC Interests for cash in connection with the IPO.

“Investor Group” refer to certain investment funds affiliated with The Blackstone Group Inc. (f/k/a The Blackstone Group L.P.), an affiliate of Canada Pension Plan Investment Board, an affiliate of GIC Special Investments Pte.

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). You can generally identify forward-looking statements by our use of forward-looking terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “projection,” “seek,” “should,” “will” or “would,” or the negative thereof or other variations thereon or comparable terminology. In particular, statements about the markets in which we operate, including our expectations about market trends, our market opportunity and the growth of our various markets, our expansion into new markets, any potential tax savings we may realize as a result of our organizational structure, our dividend policy and our expectations, beliefs, plans, strategies, objectives, prospects or assumptions regarding future events, including the pending LSEG Transaction, our performance or otherwise, contained in this Quarterly Report on Form 10-Q are forward-looking statements.

We have based these forward-looking statements on our current expectations, assumptions, estimates and projections. While we believe these expectations, assumptions, estimates and projections are reasonable, such forward-looking statements are only predictions and involve known and unknown risks and uncertainties, many of which are beyond our control. These and other important factors may cause our actual results, performance or achievements to differ materially from those expressed or implied by these forward-looking statements, or could affect our share price. Some of the factors that could cause actual results to differ materially from those expressed or implied by the forward-looking statements include:

changes in economic, political, social and market conditions and the impact of these changes on trading volumes;

4

our failure to compete successfully;

our failure to adapt our business effectively to keep pace with industry changes;

consolidation and concentration in the financial services industry;

our dependence on dealer clients that are also stockholders;

our inability to maintain and grow the capacity of our trading platforms, systems and infrastructure;

design defects, errors, failures or delays with our platforms or solutions;

systems failures, interruptions, delays in services, cybersecurity incidents, catastrophic events and any resulting interruptions;

our dependence on third parties for certain market data and certain key functions;

our ability to implement our business strategies profitably;

our ability to successfully integrate any acquisition or to realize benefits from any strategic alliances, partnerships or joint ventures;

our ability to retain the services of certain members of our management;

inadequate protection of our intellectual property;

limitations on operating our business and incurring additional indebtedness as a result of covenant restrictions under our $500.0 million senior secured revolving credit facility (the “Revolving Credit Facility”) with Citibank, N.A., as administrative agent and collateral agent, and the other lenders party thereto, and certain Refinitiv indebtedness;

our dependence on distributions from TWM LLC to fund our expected dividend payments and to pay our taxes and expenses, including payments under the tax receivable agreement (the “Tax Receivable Agreement”) entered into in connection with the IPO;

our ability to realize any benefit from our organizational structure;

Refinitiv’s control of us and our status as a controlled company; and

· other risks and uncertainties, including those listed under “Risk Factors” in our final prospectus, dated October 17, 2019 (the “October Prospectus”), filed with the Securities and Exchange Commission (“SEC”) pursuant to Rule 424(b) under the Securities Act, relating to our follow-on offering, and in other filings we may make from time to time with the SEC.

Given these risks and uncertainties, you are cautioned not to place undue reliance on such forward-looking statements. The forward-looking statements contained in this Quarterly Report on Form 10-Q are not guarantees of future performance and our actual results of operations, financial condition or liquidity, and the development of the industry and markets in which we operate, may differ materially from the forward-looking statements contained in this Quarterly Report on Form 10-Q. In addition, even if our results of operations, financial condition or liquidity, and events

5

in the industry and markets in which we operate, are consistent with the forward-looking statements contained in this Quarterly Report on Form 10-Q, they may not be predictive of results or developments in future periods.

Any forward-looking statement that we make in this Quarterly Report on Form 10-Q speaks only as of the date of such statement. Except as required by law, we do not undertake any obligation to update or revise, or to publicly announce any update or revision to, any of the forward-looking statements, whether as a result of new information, future events or otherwise, after the date of this Quarterly Report on Form 10-Q.

The information that we post through these social media channels may be deemed material. As a result, we encourage investors, the media and others interested in Tradeweb to monitor these social media channels in addition to following our press releases, SEC filings and public conference calls and webcasts. These social media channels may be updated from time to time on our investor relations website.

(1) In April 2019, the Company completed the Reorganization Transactions and the IPO, which, among other things, resulted in Tradeweb Markets Inc. becoming the successor of Tradeweb Markets LLC for financial reporting purposes. As a result, earnings per share information for the pre-IPO period is not comparable to the earnings per share information for the post-IPO period. Therefore, earnings per share information is being presented separately for the pre-IPO and post-IPO periods. See Note 18 – Earnings Per Share for additional information.

Notes to Consolidated Financial Statements

(Unaudited)

1.          Organization

Tradeweb Markets Inc. (the “Corporation”) was incorporated as a Delaware corporation on November 7, 2018 for the purpose of completing certain reorganization transactions in order to carry on the business of Tradeweb Markets LLC (“TWM LLC”) and conducting an initial public offering (“IPO”) as described below under “—Initial Public Offering” and “—Reorganization Transactions.”

The Corporation is a consolidating subsidiary of BCP York Holdings, (“BCP”) a company owned by certain investment funds affiliated with The Blackstone Group Inc. (f/k/a The Blackstone Group L.P.) (“Blackstone”), through BCP’s majority ownership interest in Refinitiv Holdings Limited (the “Parent” and, unless otherwise stated or the context otherwise requires, together with all of its subsidiaries, “Refinitiv”). As of September 30, 2019, Refinitiv owns a majority ownership interest in the Company (as defined below).  

The Corporation is a holding company whose principal asset is LLC Interests (as defined below) of TWM LLC. As the sole manager of TWM LLC, the Corporation operates and controls all of the business and affairs of TWM LLC and, through TWM LLC and its subsidiaries, conducts the Corporation’s business. As a result of this control, and because the Corporation has a substantial financial interest in TWM LLC, the Corporation consolidates the financial results of TWM LLC and reports a non-controlling interest in the Corporation’s consolidated financial statements.  As of September 30, 2019, Tradeweb Markets Inc. owns 64.3% of TWM LLC and the Continuing LLC Owners (defined below) own the remaining 35.7% of TWM LLC.

Unless the context otherwise requires, references to the “Company” refer to Tradeweb Markets Inc. and its consolidated subsidiaries, including TWM LLC, following the completion of the Reorganization Transactions (as defined below), and TWM LLC and its consolidated subsidiaries prior to the completion of the Reorganization Transactions.

The Company is a leader in building and operating electronic marketplaces for a global network of clients across the institutional, wholesale and retail client sectors. The Company’s principal subsidiaries include:

· Tradeweb LLC (“TWL”), a registered broker-dealer under the Securities Exchange Act of 1934, a member of the Financial Industry Regulatory Authority (“FINRA”), a registered independent introducing broker with the Commodities Future Trading Commission (“CFTC”) and a member of the National Futures Association (“NFA”).

Tradeweb Europe Limited (“TEL”), a Multilateral Trading Facility regulated by the Financial Conduct Authority (the “FCA”) in the UK, which maintains branches in Asia which are regulated by certain Asian securities regulators.

TW SEF LLC (“TW SEF”), a Swap Execution Facility (“SEF”) regulated by the CFTC.

DW SEF LLC (“DW SEF”), a SEF regulated by the CFTC.

Tradeweb Japan K.K. (“TWJ”), a security house regulated by the Japanese Financial Services Agency (“JFSA”) and the Japan Securities Dealers Association (“JSDA”).

Tradeweb EU B.V. (“TWEU”), a Trading Venue and Approved Publication Arrangement regulated by the Netherlands Authority for the Financial Markets (“AFM”).

14

The Company, through its subsidiary Tradeweb IDB Markets Inc. (“TWIDB”) (formerly known as Hydrogen Holdings Corporation), owns Dealerweb Inc. (“DW”) (formerly known as Hilliard Farber & Co., Inc.). DW is a registered broker-dealer under the Securities Exchange Act of 1934 and a member of FINRA. DW is also registered as an introducing broker with the CFTC and NFA.

The Company, through its subsidiary BondDesk Group LLC, owns Tradeweb Direct LLC (“TWD”) (formerly known as BondDesk Trading LLC), a registered broker-dealer under the Securities Exchange Act of 1934 and a member of FINRA.

Initial Public Offering

On April 8, 2019, the Corporation completed its IPO of 46,000,000 shares of Class A common stock at a public offering price of $27.00, which included 6,000,000 shares of Class A common stock issued pursuant to the underwriters’ option to purchase additional shares of Class A common stock.  The Corporation received $1.2 billion in net proceeds, after deducting underwriting discounts and commissions but before deducting offering expenses, which were used to purchase membership interests of TWM LLC from certain existing equityholders of TWM LLC (and the corresponding shares of common stock were cancelled as described below), at a purchase price per interest equal to the public offering price of $27.00, less the underwriting discounts and commissions payable thereon.

Reorganization Transactions

Prior to the closing of the IPO, a series of reorganization transactions (the “Reorganization Transactions”) was completed among the Corporation, TWM LLC and the owners of TWM LLC prior to the Reorganization Transactions (collectively, the “Original LLC Owners”), including the following parties:

certain investment and commercial banks (collectively, the “Bank Stockholders”);

members of management;

the Refinitiv Direct Owner, (i) prior to June 28, 2019, a direct subsidiary of Refinitiv that owned interests in an entity that held membership interests of TWM LLC prior to the Reorganization Transactions and contributed such entity to the Corporation (the “Refinitiv Contribution”) in exchange for shares of the Corporation’s Class B common stock in connection with the completion of the Reorganization Transactions and (ii) on and after June 28, 2019, an indirect subsidiary of Refinitiv that owns shares of the Corporation’s Class B common stock which shares were contributed by the direct subsidiary of Refinitiv referred to in the foregoing clause (i); and

an indirect subsidiary (the “Refinitiv LLC Owner” and, together with the Refinitiv Direct Owner, the “Refinitiv Owners”) of Refinitiv.

As used herein, references to “Continuing LLC Owners” refer collectively to (i) those Original LLC Owners, including the Refinitiv LLC Owner, certain Bank Stockholders and members of management, that continue to own LLC Interests (as defined below) after the completion of the IPO and Reorganization Transactions, that received shares of the Corporation’s Class C common stock, shares of the Corporation’s Class D common stock or a combination of both, as the case may be, in connection with the completion of the Reorganization Transactions, and that may redeem or exchange their LLC Interests for shares of the Corporation’s Class A common stock or Class B common stock and (ii) solely with respect to the Tax Receivable Agreement (as defined below), also includes those Original LLC Owners, including certain Bank Stockholders, that disposed of all of their LLC Interests for cash in connection with the IPO.

The following Reorganization Transactions occurred:

TWM LLC’s limited liability company agreement (the “TWM LLC Agreement”) was amended and restated to, among other things, (i) provide for a new single class of common membership interests in TWM LLC (“LLC Interests”), (ii) exchange all of the then existing membership interests in TWM LLC for

15

LLC Interests and (iii) appoint the Corporation as the sole manager of TWM LLC. See Note 11 – Stockholders’ Equity.

The Corporation’s certificate of incorporation was amended and restated to, among other things, provide for Class A common stock, Class B common stock, Class C common stock and Class D common stock. See Note 11 – Stockholders’ Equity.

· The Corporation issued 20,000,000 shares of Class C common stock and 105,289,005 shares of Class D common stock to the  Original LLC Owners that received LLC Interests on a one-to-one basis with the number of LLC Interests they owned immediately following the amendment and restatement of the TWM LLC Agreement for nominal consideration (and the Corporation subsequently cancelled 9,993,731 shares of such Class C common stock and 36,006,269 shares of such Class D common stock in connection with the Corporation’s purchase of LLC Interests from certain of the Bank Stockholders using the net proceeds of the IPO).

· As a result of the Refinitiv Contribution (described above), the Corporation received 96,933,192 LLC Interests and the Refinitiv Direct Owner received 96,933,192 shares of Class B common stock. See Note 11 – Stockholders’ Equity.

The Corporation’s board of directors adopted a new omnibus equity incentive plan, under which equity awards may be made in respect of shares of the Corporation’s Class A common stock. It also assumed sponsorship of an option plan and PRSU plan formerly sponsored by TWM LLC. See Note 13 – Stock-Based Compensation Plans.

The Corporation entered into a tax receivable agreement (the “Tax Receivable Agreement”) with TWM LLC and the Continuing LLC Owners. See Note 10 – Tax Receivable Agreement.

2.          Significant Accounting Policies

The following is a summary of significant accounting policies:

Basis of Accounting

The consolidated financial statements have been presented in conformity with accounting principles generally accepted in the United States of America. All adjustments, which are, in the opinion of management, necessary to a fair statement of the results for the interim periods presented, are normal and recurring in nature. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and the difference may be material to the consolidated financial statements.

Basis of Presentation and Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

As discussed in Note 1—Organization, as a result of the Reorganization Transactions, Tradeweb Markets Inc. consolidates TWM LLC and TWM LLC is considered to be the predecessor to Tradeweb Markets Inc. for financial reporting purposes. As a result, the consolidated financial statements for periods prior to the Reorganization Transactions have been adjusted to combine the previously separate entities for presentation purposes. However, Tradeweb Markets Inc. had no business transactions or activities and no substantial assets or liabilities prior to the Reorganization Transactions. As such, for periods prior to the completion of the Reorganization Transactions, the consolidated financial statements represent the historical financial condition and results of operations of TWM LLC and its subsidiaries. For periods after the completion of the Reorganization Transactions, the consolidated financial statements represent the financial condition and results of operations of the Company and report a non-controlling interest related to the LLC Interests held by the Continuing LLC Owners.

Cash and Cash Equivalents

Cash and cash equivalents consists of cash and highly liquid investments (such as short-term money market instruments) with original maturities of less than three months.

Allowance for Doubtful Accounts

The Company continually monitors collections and payments from its clients and maintains an allowance for doubtful accounts. The allowance for doubtful accounts is based upon the historical collection experience and specific collection issues that have been identified. Additions, if any, to the allowance for doubtful accounts are charged to bad debt expense, which is included in general and administrative expenses on the consolidated statements of income.

Furniture, Equipment, Purchased Software and Leasehold Improvements

Furniture, equipment, purchased software and leasehold improvements are carried at cost less accumulated depreciation. Depreciation for furniture, equipment and purchased software, including the allocated fair value of assets as a result of pushdown accounting (see Note 3 – Pushdown Accounting), is computed on a straight-line basis over the estimated useful lives of the related assets, ranging from three to seven years. Leasehold improvements are amortized over the lesser of the estimated useful lives of the leasehold improvements or the remaining term of the lease for office space.

17

Furniture, equipment, purchased software and leasehold improvements are tested for impairment whenever events or changes in circumstances suggest that an asset’s carrying value may not be fully recoverable in accordance with Accounting Standards Codification (“ASC”) 360.

Software Development Costs

The Company capitalizes costs associated with the development of internal use software at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed, in accordance with ASC 350. The Company capitalizes employee compensation and related benefits and third party consulting costs incurred during the application development stage which directly contribute to such development. Such costs are amortized on a straight-line basis over three years. Costs capitalized as part of the pushdown accounting allocation (see Note 3 – Pushdown Accounting) are amortized over nine years. The Company reviews the amounts capitalized for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable, or that their useful lives are shorter than originally expected. Non-capitalized software costs and routine maintenance costs are expensed as incurred.

Intangible Assets

Intangible assets with a finite life are amortized over the estimated lives, ranging from seven to sixteen years, in accordance with ASC 350. Intangible assets subject to amortization are tested for impairment whenever events or changes in circumstances suggest that an asset's or asset group's carrying value may not be fully recoverable in accordance with ASC 360. Intangible assets with an indefinite useful life are tested for impairment at least annually. An impairment loss is recognized if the sum of the estimated discounted cash flows relating to the asset or asset group is less than the corresponding book value.

Goodwill

Goodwill is the excess of the fair value of the Company above the fair value accounting basis of the net assets and liabilities of the Company under pushdown accounting. Goodwill is also the cost of acquired companies in excess of the fair value of identifiable net assets at the acquisition date. Goodwill is not amortized, but in accordance with ASC 350, goodwill is tested for impairment annually and between annual tests whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. Goodwill is tested at the reporting unit level, which is defined as an operating segment or one level below the operating segment. An impairment loss is recognized if the estimated fair value of a reporting unit is less than its net book value. Such loss is calculated as the difference between the estimated fair value of goodwill and its carrying value.

In 2019, the Company changed the annual date on which goodwill is tested for impairment from July 1st to October 1st to align with the annual impairment testing date of the Company’s Parent. This change did not accelerate, delay, avoid or cause an impairment charge, nor did this change result in adjustments to any previously issued financial statements. Goodwill was last assessed on October 1, 2018 in connection with the Refinitiv Transaction and the application of pushdown accounting.  See Note 3 – Pushdown Accounting.

Deferred IPO and Follow-On Offering Costs

In 2018 and the third quarter of 2019, the Company began incurring costs in connection with the filing of a Registration Statement on Form S-1 for an IPO and a Registration Statement on Form S-1 for a follow-on offering, respectively, which are deferred in other assets in accordance with ASC 505-10-25 in the consolidated statements of financial condition. IPO and follow-on offering costs consist of legal, accounting, and other costs directly related to the Company’s efforts to raise capital. As of September 30, 2019, $15.9 million of deferred costs related to the IPO were reclassified from other assets to additional paid-in capital and $0.7 million of deferred costs related to the follow-on offering were included in other assets, in each case on the consolidated statements of financial condition.  See Note 11 – Stockholders’ Equity and Note 21 – Subsequent Events.

18

Translation of Foreign Currency

Revenues and expenses denominated in foreign currencies are translated at the rate of exchange prevailing at the transaction date. Assets and liabilities denominated in foreign currencies are translated at the rate prevailing at the consolidated statements of financial condition date. Foreign currency re-measurement gains or losses on transactions in nonfunctional currencies are recognized in the consolidated statements of income. Gains or losses on translation in the financial statements of a non-U.S. operation, when the functional currency is other than the U.S. dollar, are included as a component of comprehensive income.

Income Tax

The Corporation is subject to U.S. federal, state and local income taxes with respect to its taxable income, including its allocable share of any taxable income of TWM LLC, and is taxed at prevailing corporate tax rates. TWM LLC is a multiple member limited liability company taxed as a partnership and accordingly any taxable income generated by TWM LLC is passed through to and included in the taxable income of its members, including the Corporation, on a pro rata basis. Income taxes also include unincorporated business taxes on income earned or losses incurred for conducting business in certain state and local jurisdictions, income taxes on income earned or losses incurred in foreign jurisdictions on certain operations and federal and state income taxes on income earned or losses incurred, both current and deferred, on subsidiaries that are taxed as corporations for U.S. tax purposes.

The Company records deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. The Company measures deferred taxes using the enacted tax rates and laws that will be in effect when such temporary differences are expected to reverse. Based on the weight of the positive and negative evidence considered, management believes that it is more likely than not that the Company will be able to realize its deferred tax assets in the future, therefore, no valuation allowance is necessary.

The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process whereby (i) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (ii) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

The Company recognizes interest and penalties related to income taxes within the provision for income taxes in the consolidated statements of income. Accrued interest and penalties are included within accounts payable, accrued expenses and other liabilities in the consolidated statements of financial condition.

The Company has elected to treat taxes due on future U.S. inclusions in taxable income under the global intangible low-taxed income (“GILTI”) provision of the Tax Cuts and Jobs Act as a current period expense when incurred.

Revenue Recognition

The Company earns transaction fees from transactions executed on the Company’s trading platforms through various fee plans. Transaction fees are generated both on a variable and fixed price basis and vary by geographic region, product type and trade size. For variable transaction fees, the Company charges clients fees based on the mix of products traded and the volume of transactions executed. Transaction fee revenue is recorded at a point in time when the trade occurs and is generally billed monthly.

The Company earns subscription fees from granting access to institutional investors to the Company's electronic marketplaces. Subscription fees are recognized into income in the period that access is provided on a monthly basis. Also included in subscription fees are viewer fees earned monthly from institutional investors accessing fixed income market data. The frequency of subscription fee billings varies from monthly to annually, depending on contract terms. Fees received by the Company which are not yet earned are included in deferred revenue on the consolidated statements of financial condition until the revenue recognition criteria has been met.

19

The Company earns commission revenue from its electronic and voice brokerage services on a riskless principal basis. Riskless principal revenues are derived on matched principal transactions where revenues are earned on the spread between the buy and sell price of the transacted product. Securities transactions and related commission income for brokerage transactions are recognized and recorded on a trade-date basis. Commission revenue is collected by the Company when the trade settles or is billed monthly.

The Company earns fees from Refinitiv, formerly TR in the predecessor periods, relating to the sale of market data to Refinitiv, which redistributes that data. Included in these fees, which are billed quarterly, are real-time market data fees which are recognized in the period that the data is provided, generally on a monthly basis and historical data sets which are recognized when the historical data set is provided to Refinitiv.

On January 1, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers, using the modified retrospective approach. The adoption of ASU 2014-09 did not have a material impact on the measurement or recognition of revenue in any prior reporting periods.  However, subsequent to the adoption, the Company was required to make significant judgements for the Refinitiv market data fees.  Significant judgements used in accounting for this contract include:

· The provision of real-time market data feeds and annual historical data sets are distinct performance obligations.

· The performance obligations under this contract are recognized over time from the initial delivery of the data feeds or each historical data set until the end of the contract term.

· Determining the transaction price for the performance obligations by using a market assessment analysis. Inputs in this analysis include a consultant study which determined the overall value of the Company's market data and pricing information for historical data sets provided by other companies.

Some revenues earned by the Company have fixed fee components, such as monthly minimums or fixed monthly fees, and variable components, such as transaction based fees. The breakdown of revenues between fixed and variable revenues, in thousands, for the three and nine months ended September 30, 2019 and 2018 is as follows:

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718. ASC 718 focuses primarily on accounting for a transaction in which an entity obtains employee services in exchange for stock-based payments. Under ASC 718, the stock-based payments received by the employees of the Company are accounted for either as equity awards or as liability awards.

20

As an equity award, the Company measures and recognizes the cost of employee services received in exchange for awards of equity instruments based on their estimated fair values measured as of the grant date. These costs are recognized as an expense over the requisite service period, with an offsetting increase to additional paid-in capital.

As a liability award, the cost of employee services received in exchange for an award of equity instruments is generally measured based on the grant-date fair value of the award. The fair value of that award is remeasured subsequently at each reporting date through the settlement in accordance with ASC 505. Changes in the equity instrument's fair value during the requisite service period are recognized as compensation cost over that period.

For periods following the Reorganization Transactions and the IPO, the fair value of new equity instrument grants is determined based on the price of the Company’s Class A common stock on the grant date.

Under ASC 718, the grant-date fair value of stock-based awards that do not require future service (i.e., vested awards) are expensed immediately. The grant-date fair value of stock-based awards that require future service, and are graded-vesting awards, are amortized over the relevant service period on a straight-line basis, with each tranche separately measured. The grant-date fair value of stock-based awards that require both future service and the achievement of Company performance-based conditions, are amortized over the relevant service period for the performance-based condition. If in a reporting period it is determined that the achievement of a performance target for a performance-based tranche is not probable, then no expense is recognized for that tranche and any expenses already recognized relating to that tranche in prior reporting periods are reversed in the current reporting period.

Prior to the IPO, the Company awarded options to management and other employees (collectively, the “Special Option Award”) under the Amended and Restated Tradeweb Markets Inc. Option Plan (the “Option Plan”). In accounting for the options issued under the Option Plan, compensation expense is measured and recognized for all awards based on their estimated fair values measured as of the grant date. Costs related to these options are recognized as an expense in the consolidated statements of income over the requisite service period, with an offsetting increase to additional paid-in capital. The non-cash stock-based compensation expense associated with the Special Option Award began being expensed in the second quarter of 2019 and will continue to be expensed over the following three years.

Determining the appropriate fair value model and calculating the fair value of the stock-based awards requires the input of highly subjective assumptions, including the expected life of the stock-based awards and the stock price volatility. The Company uses the Black-Scholes pricing model to value some of its stock-based awards.

Earnings Per Share

Basic earnings per share is computed by dividing the net income attributable to the Company's shares by the weighted-average number of the Company's shares outstanding during the period. For purposes of computing diluted earnings per share, the weighted-average number of the Company’s shares reflects the dilutive effect that could occur if securities that qualify as participating securities were converted into or exchanged or exercised for TWM LLC’s shares, in the pre-IPO period, and the Corporation’s Class A or Class B common stock, in the post-IPO period, using the treasury stock method, as applicable.

Shares of Class C and Class D common stock do not have economic rights in Tradeweb Markets Inc. and, therefore, are not participating securities for purposes of the computation of earnings per share.

Fair Value Measurement

The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). Instruments that the Company owns (long positions) are marked to bid prices, and instruments that the Company has sold, but not yet purchased (short positions) are marked to offer prices. Fair value measurements do not include transaction costs.

21

The fair value hierarchy under ASC 820 prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under ASC 820 are described below:

Basis of Fair Value Measurement

Level 1:Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: Quoted prices in markets that are not considered to be active or financial instruments for which all significant inputs are observable, either directly or indirectly;

Level 3: Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Recent Accounting Pronouncements – Not Yet Adopted

In June 2016, the FASB issued ASU 2016‑13, Financial Instruments – Credit Losses. The ASU provides new guidance for estimating credit losses on certain types of financial instruments by introducing an approach based on expected losses. This ASU is applicable for the Company in the fiscal year beginning January 1, 2020 and requires a modified retrospective method of adoption. The Company is currently in the planning and analysis phase, which involves documenting in-scope financial assets and understanding and leveraging existing credit loss estimation processes.

The Company does not anticipate the adoption of this ASU to have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017‑04, Intangibles – Goodwill and Other. The ASU simplifies the quantitative goodwill impairment test by eliminating the second step of the test. Under this ASU, impairment will be measured by comparing the estimated fair value of the reporting unit with its carrying value. The ASU is applicable for the Company in the fiscal year beginning January 1, 2020. The Company does not anticipate the adoption of this ASU to have a material impact on the Company's consolidated financial statements.

3.          Pushdown Accounting

The Refinitiv Transaction was accounted for by Refinitiv in accordance with the acquisition method of accounting pursuant to ASC 805, and pushdown accounting was applied to Refinitiv to record the fair value of the assets and liabilities of Refinitiv on the date of the Refinitiv Transaction. The Company, as a consolidating subsidiary of Refinitiv, also accounted for the Refinitiv Transaction using pushdown accounting. Under pushdown accounting, the excess of the fair value of the Company above the fair value accounting basis of the net assets and liabilities of the Company was recorded as goodwill. At September 30, 2019 and December 31, 2018, goodwill amounted to $2.7 billion.

The adjusted valuations resulted in an increase in depreciation and amortization expense, due to the increased carrying value of the Company’s assets and the related increase in depreciation of tangible assets and amortization of intangible assets, and a decrease in occupancy expense as a result of the recognition of a leasehold interest liability.

4.          Receivable from and Payable to Brokers and Dealers and Clearing Organizations

Receivables from and payables to brokers and dealers and clearing organizations consist of proceeds from transactions which failed to settle due to the inability of a transaction party to deliver or receive the transacted security. These securities transactions are generally collateralized by those securities.

22

On October 1, 2019, approximately $698.8 million and $664.3 million, respectively, of the receivable from and payable to balances outstanding at September 30, 2019 were settled.

5.          Securities Sold Under Agreements to Repurchase

The Company enters into agreements to repurchase from time to time to facilitate the clearance of securities.

At September 30, 2019, securities sold from agreements to repurchase amounted to $24.9 million and related to an overnight repurchase agreement with a maturity date of October 1, 2019.

The following table provides additional information regarding this agreement to repurchase (in thousands):

	September 30,		December 31,
	2019		2018
Agreements to repurchase:
U.S. Treasury Note	$	24,938	$	—
Total agreements to repurchase	$	24,938	$	—
Gross amount of recognized liabilities for agreements to repurchase	$	24,938	$	—

Securities sold under agreements to repurchase are treated as collateralized financings and are presented on the consolidated statement of financial condition at the amounts of cash received, which approximates fair value.  Receivables and payables arising from these agreements are not offset on the statement of financial condition.

6.          Leases

Effective January 1, 2019, the Company adopted ASC 842, Leases. This standard requires the Company to recognize a right-of-use asset and a lease liability for all leases with an initial term in excess of twelve months. The Company accounts for an option to extend a lease when the option is reasonably certain to be exercised. The asset reflects the present value of unpaid lease payments coupled with initial direct costs, prepaid lease payments and lease incentives. The amount of the lease liability is calculated as the present value of unpaid lease payments. The Company adopted ASC 842 using a modified retrospective approach and did not restate comparative periods. The Company elected to take the package of practical expedients allowing the Company to not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for any existing leases.  The Company has elected to account for nonlease components in a contract as part of the single lease component to which they are related.

Significant assumptions and judgements in calculating the right-of-use assets and lease liability include the determination of the applicable borrowing rate for each lease.

On January 1, 2019, upon the adoption of ASC 842, the Company recorded, for office space and data center leases in the U.S. and U.K., right-of-use assets of $34.8 million, lease liabilities of $39.6 million and eliminated deferred rent of $4.9 million. The leases have initial lease terms ranging from three to 11 years.

Activity related to the Company's leases for the three and nine months ended September 30, 2019 is as follows (in thousands):

	ThreeMonths		NineMonths

9.          Income Taxes

The Company's effective tax rate was 17.5% and 14.1% for the three months ended September 30, 2019 and 2018, respectively, and 15.6% and 8.4% for the nine months ended September 30, 2019 and 2018, respectively. The increase in the effective tax rate for the three months and nine months ended September 30, 2019 was primarily due to the Reorganization Transactions. Prior to the Reorganization Transactions, income taxes consisted only of business taxes incurred by TWM LLC and certain subsidiaries for business conducted in certain state, local and foreign jurisdictions as well as federal, state and local taxes for certain subsidiaries that are taxed as corporations for U.S. tax purposes. As a result of the Reorganization Transactions, the Corporation is subject to U.S. federal, state and local income taxes with respect to its taxable income, including its allocable share of any taxable income of TWM LLC, and is taxed at prevailing corporate tax rates. The Company’s actual effective tax rate will be impacted by the Corporation’s ownership share of TWM LLC, which will increase over time as the Continuing LLC Owners redeem or exchange their LLC Interests for shares of Class A common stock or Class B common stock, as applicable, or the Corporation purchases LLC Interests from the Continuing LLC Owners.

25

The Company's consolidated effective tax rate will vary from period to period depending on redemptions, exchanges or purchases of LLC Interests as described above, changes in the geographic mix of its earnings and changes in tax legislation and tax rates.

The Company expects to obtain an increase in its share of the tax basis of the assets of TWM LLC when LLC Interests are redeemed or exchanged by the Continuing LLC Owners and in connection with certain other qualifying transactions. This increase in tax basis may have the effect of reducing the amounts that the Corporation would otherwise pay in the future to various tax authorities. Pursuant to the Tax Receivable Agreement, the Corporation is required to make cash payments to the Continuing LLC Owners equal to 50% of the amount of U.S. federal, state and local income or franchise tax savings, if any, that the Corporation actually realizes (or in some circumstances are deemed to realize) as a result of certain future tax benefits to which we may become entitled. The Corporation expects to benefit from the remaining 50% of tax benefits, if any, that the Corporation may actually realize. See Note 10 – Tax Receivable Agreement. As a result of the IPO, the Company assumed a tax benefit of $93.2 million, primarily due to an increase in amortizable tax basis that will be amortized primarily over 15 years pursuant to Section 197 of the Internal Revenue Code of 1986, as amended, offset by other factors. The tax benefit has been recognized in deferred tax asset on the September 30, 2019 consolidated statement of financial condition.

As a result of the Refinitiv Contribution, the Company assumed the tax liabilities of the contributed entity. The contributed entity is under audit by the State of New Jersey for the tax years 2012-2015 and is appealing a tax assessment from an audit by the State of New Jersey for the tax years 2008-2011. At September 30, 2019, the tax liability related to the Refinitiv Contribution is $2.8 million and is included within accounts payable, accrued expenses and other liabilities on the consolidated statement of financial condition.  The Company is indemnified by Refinitiv for tax liabilities that were assumed by the Company as a result of the Refinitiv Contribution. See Note 14 – Related Party Transactions.

10.          Tax Receivable Agreement

In connection with the Reorganization Transactions, the Corporation entered into the Tax Receivable Agreement with TWM LLC and the Continuing LLC Owners, which provides for the payment by the Corporation to a Continuing LLC Owner of 50% of the amount of U.S. federal, state and local income or franchise tax savings, if any, that the Corporation actually realizes (or in some circumstances is deemed to realize) as a result of (i) increases in the tax basis of TWM LLC’s assets resulting from (a) the purchase of LLC Interests from such Continuing LLC Owner, including with the net proceeds from the IPO and any future offering or (b) redemptions or exchanges by such Continuing LLC Owner of LLC Interests for shares of Class A common stock or Class B common stock or for cash, as applicable, and (ii) certain other tax benefits related to the Corporation making payments under the Tax Receivable Agreement. Payments under the Tax Receivable Agreement are made annually based on the actual tax savings realized by the Corporation in its previous tax year.

In connection with the IPO, the Company recorded an initial liability of $171.4 million related to its projected obligations under the Tax Receivable Agreement with respect to LLC Interests that were purchased by the Corporation using the net proceeds of the IPO.

The Corporation accounts for the income tax effects resulting from taxable redemptions or exchanges of LLC Interests by the Continuing LLC Owners for shares of Class A common stock or Class B common stock or cash, as the case may be, and purchases by the Corporation of LLC Interests from the Continuing LLC Owners by recognizing an increase in deferred tax assets, based on enacted tax rates at the date of each redemption or exchange, as the case may be. Further, the Corporation evaluates the likelihood that it will realize the benefit represented by the deferred tax asset, and, to the extent that the Corporation estimates that it is more likely than not that it will not realize the benefit, it reduces the carrying amount of the deferred tax asset with a valuation allowance.

The impact of any changes in the projected obligations under the Tax Receivable Agreement as a result of changes in the geographic mix of the Company’s earnings, changes in tax legislation and tax rates or other factors that may impact the Corporation’s tax savings will be reflected in income before taxes on the consolidated statement of income in the period in which the change occurs.

11.          Stockholders’ Equity

Initial Public Offering

As described in Note 1 – Organization, in April 2019, the Corporation completed its IPO of 46,000,000 shares of Class A common stock at a public offering price of $27.00, which included 6,000,000 shares of Class A common stock issued pursuant to the underwriters’ option to purchase additional shares of Class A common stock.  The Corporation received $1.2 billion in net proceeds, after deducting underwriting discounts and commissions but before deducting offering expenses, which were used to purchase LLC Interests from certain of the Bank Stockholders (and the corresponding shares of common stock were cancelled as described below), at a purchase price per interest equal to the public offering price of $27.00, less the underwriting discounts and commissions payable thereon.

Reorganization Transactions

In connection with the IPO, the Reorganization Transactions described below were completed.

Amendment and Restatement of Certificate of Incorporation

On April 3, 2019, the certificate of incorporation of Tradeweb Markets Inc. was amended and restated to, among other things, provide for the authorization of (i) 250,000,000 shares of preferred stock with a par value of $0.00001 per share (ii) 1,000,000,000 shares of Class A common stock with a par value of $0.00001 per share; (iii) 450,000,000 shares of Class B common stock with a par value of $0.00001 per share; (iv) 350,000,000 shares of Class C common stock with a par value of $0.00001 per share; and (v) 300,000,000 shares of Class D common stock with a par value of $0.00001 per share.

Each share of Class A common stock and Class C common stock entitles its holder to one vote on all matters presented to the Corporation’s stockholders generally. Each share of Class B common stock and Class D common stock entitles its holder to ten votes on all matters presented to the Corporation’s stockholders generally. The holders of Class C common stock and Class D common stock have no economic interests in the Corporation (where “economic interests” means the right to receive any dividends or distributions, whether cash or stock, in connection with common stock). These attributes are summarized in the following table:

Class of Common Stock	Par Value		Votes	Economic Rights
Class A common stock	$	0.00001	1	Yes
Class B common stock	$	0.00001	10	Yes
Class C common stock	$	0.00001	1	No
Class D common stock	$	0.00001	10	No

Holders of outstanding shares of Class A common stock, Class B common stock, Class C common stock and Class D common stock will vote together as a single class on all matters presented to the Corporation’s stockholders for their vote or approval, except as otherwise required by applicable law.

Holders of Class B common stock may from time to time exchange all or a portion of their shares of Class B common stock for newly issued shares of Class A common stock on a one-for-one basis (in which case their shares of Class B common stock will be cancelled on a one-for-one basis upon any such issuance). The Continuing LLC Owners that hold shares of Class D common stock may also from time to time exchange all or a portion of their shares of Class D common stock for newly issued shares of Class C common stock on a one-for-one basis (in which case their shares of Class D common stock will be cancelled on a one-for-one basis upon such issuance). In addition, with respect to each Bank Stockholder that holds shares of Class D common stock, immediately prior to the occurrence of any event that would cause the combined voting power held by such Bank Stockholder to exceed 4.9%, the minimum number of shares of Class D common stock of such Bank Stockholder that would need to convert into shares of Class C common stock such

27

that the combined voting power held by such Bank Stockholder would not exceed 4.9% will automatically convert into shares of Class C common stock.

Each share of Class B common stock will automatically convert into one share of Class A common stock and each share of Class D common stock will automatically convert into one share of Class C common stock (i) immediately prior to any sale or other transfer of such share by a holder or its permitted transferees to a non-permitted transferee or (ii) once the Refinitiv Owners and their affiliates together no longer beneficially own a number of shares of common stock and LLC Interests that together entitle them to at least 10% of TWM LLC’s economic interest. Holders of LLC Interests that receive shares of Class C common stock upon any such conversion may continue to elect to have their LLC Interests redeemed for newly issued shares of Class A common stock as described below (in which case their shares of Class C common stock will be cancelled on a one-for-one basis upon such issuance).

Recapitalization of Tradeweb Markets LLC

On April 4, 2019, the TWM LLC Agreement was amended and restated to, among other things, (i) provide for the LLC Interests, (ii) exchange all of the then existing membership interests in TWM LLC for LLC Interests and (iii) appoint the Corporation as the sole manager of TWM LLC.

All of the shares of TWM LLC outstanding prior to the Reorganization Transactions were exchanged for 222,222,197 LLC Interests. TWM LLC’s outstanding shares prior to the Reorganization Transactions consisted of the following classes of shares:

	Shares
Class A	146,333
Class C	447
Class P (A)	6,887
Class P (C)	2
Class P-1(A)	6,094
Class P-1 (C)	232

The TWM LLC Agreement requires that TWM LLC at all times maintain (i) a one-to-one ratio between the number of shares of Class A common stock and Class B common stock issued by the Corporation and the number of LLC Interests owned by the Corporation and (ii) a one-to-one ratio between the number of shares of Class C common stock and Class D common stock issued by the Corporation and the number of LLC Interests owned by the holders of such Class C common stock and Class D common stock.

LLC Interests held by the Continuing LLC Owners are redeemable in accordance with the TWM LLC Agreement, at the election of such holders, for newly issued shares of Class A common stock or Class B common stock, as the case may be, on a one-for-one basis (and such holders’ shares of Class C common stock or Class D common stock, as the case may be, will be cancelled on a one-for-one basis upon any such issuance). In the event of such election by a Continuing LLC Owner, the Corporation may, at its option, effect a direct exchange of Class A common stock or Class B common stock for such LLC Interests of such Continuing LLC Owner in lieu of such redemption. In addition, the Corporation’s board of directors may, at its option, instead of the foregoing redemptions or exchanges of LLC Interests, cause the Corporation to make a cash payment equal to the volume weighted average market price of one share of Class A common stock for each LLC Interest redeemed or exchanged (subject to customary adjustments, including for stock splits, stock dividends and reclassifications) in accordance with the terms of the TWM LLC Agreement.

Issuance and Cancellation of Common Stock

· As a result of the Refinitiv Contribution, the Corporation received 96,933,192 LLC Interests and the Refinitiv Direct Owner received 96,933,192 shares of Class B common stock.

28

· The Corporation issued 20,000,000 shares of Class C common stock and 105,289,005 shares of Class D common stock to the Original LLC Owners that received LLC Interests on a one-to-one basis with the number of LLC Interests they owned immediately following the amendment and restatement of the TWM LLC Agreement for nominal consideration (the Corporation subsequently cancelled 9,993,731 shares of such Class C common stock and 36,006,269 shares of such Class D common stock in connection with the Corporation’s purchase of LLC Interests from certain of the Bank Stockholders using the net proceeds of the IPO).

Following the completion of the Reorganization Transactions, including the IPO and the application of the proceeds therefrom as described above, (i) the investors in the IPO collectively owned 46,000,000 shares of Class A common, representing 2.7% of the combined voting power of all of the Corporation’s common stock and, through the Corporation’s ownership of LLC Interests, 20.7% of the economic interest in TWM LLC; (ii) the Refinitiv Direct Owner owned 96,933,192 shares of Class B common stock, representing 56.4% of the combined voting power of all of the Corporation’s common stock and, through the Corporation’s ownership of LLC Interests, 43.6% of the economic interest in TWM LLC; (iii) the Refinitiv LLC Owner owned 22,988,329 shares of Class D common stock, representing 13.4% of the combined voting power of all of the Corporation’s common stock, and 22,988,329 LLC Interests, representing 10.3% of the economic interest in TWM LLC, (iv) the Continuing LLC Owners (other than the Refinitiv LLC Owner) collectively owned 10,006,269 shares of Class C common stock and 46,294,407 shares of Class D common stock, representing 27.5% of the combined voting power of all of the Corporation’s common stock, and 56,300,676 LLC Interests, representing 25.3% of the economic interest in TWM LLC; and (v) the Corporation owned 142,933,192 LLC Interests, representing 64.3% of the economic interest in TWM LLC.

12.          Non-Controlling Interests

In connection with the Reorganization Transactions, Tradeweb Markets Inc. became the sole manager of TWM LLC and, as a result of this control, and because Tradeweb Markets Inc. has a substantial financial interest in TWM LLC, consolidates the financial results of TWM LLC into its consolidated financial statements. The non-controlling interests balance reported on the consolidated statements of financial condition represents the economic interests of TWM LLC held by the holders of LLC Interests other than Tradeweb Markets Inc. Income or loss is attributed to the non-controlling interests based on the relative ownership percentages of LLC Interests held during the period by Tradeweb Markets Inc. and the other holders of LLC Interests.

The following table summarizes the ownership interest in Tradeweb Markets LLC:

	September 30, 2019
	LLC	Ownership

13.          Stock-Based Compensation Plans

The Company maintains a stock-based incentive plan (the “PRSU Plan”) which provides for the grant of performance-based restricted share units (“PRSUs”) to encourage employees of the Company to participate in the long-term success of the Company.

PRSUs generally vest in the third plan year following the year of grant and are equity-settled in shares of Class A common stock (except as described below). The outstanding PRSUs vest on January 1, 2020, 2021 and 2022.  The number of PRSUs initially awarded is subsequently adjusted (upward or downward) by a performance modifier, based on the financial performance of the Company in the year of the grant.  If an employee’s employment with the Company is terminated, subject to certain exceptions, all unvested PRSUs are forfeited.

The following table summarizes information for equity-settled PRSUs of the Company (in thousands, except weighted average grant date fair value per unit):

	Successor		Successor
	Three Months		Nine Months

Weighted-average grant date fair value per unit	$	21.65	$	21.65
Total fair value of vested PRSUs	$	—	$	—

The Company previously granted cash-settled PRSUs, some of which are still outstanding and are accounted for as liability awards. The Company measures the cost of employee services received in exchange for the award based on the fair value of the Company and the value of accumulated dividend rights associated with each award. The fair value of that award is remeasured subsequently at each reporting date through to settlement. Changes in the award's fair value during the requisite service period is recognized as compensation cost over that period.

The Company maintains the Option Plan which provides for the grant of stock options. Prior to the IPO, the Company awarded options to management and other employees under the Option Plan. Each option vests one half based solely on the passage of time and one half only if the Company achieves certain performance targets. The time vesting portion of the options has a graded vesting schedule with vesting dates of January 1, 2019, 2020, 2021 and 2022, with accelerated vesting for time-based options with vesting dates of January 1, 2021 and 2022 upon the completion of an initial public offering.

In accounting for the options issued under the Option Plan, the Company measures and recognizes compensation expense for all awards based on their estimated fair values measured as of the grant date. These options are exercisable only any time following the closing of an initial public offering or during a 15‑day period following a change in control of the Company (and certain other sales of equity by the Company’s shareholders). Costs related to these options are recognized as an expense in the consolidated statements of income over the requisite service period, when exercisability is considered probable, with an offsetting increase to additional paid-in capital. As a result, expense recognition commenced upon the completion of the IPO, with $18.9 million recognized as compensation expense related to these options immediately upon the completion of the IPO.

14.          Related Party Transactions

The Company enters into transactions with Refinitiv and its affiliates which are considered to be related party transactions. The Company also enters into transactions with the Bank Stockholders and their respective affiliates. Prior to the Reorganization Transactions, the Bank Stockholders were collectively considered to be related parties of the Company. As a result of the Reorganization Transactions, they are no longer considered to be related parties. As a result, the related party transactions listed below include transactions with affiliates of Refinitiv for all periods presented and only includes transactions with affiliates of the Bank Stockholders for pre-IPO periods.

At September 30, 2019 and December 31, 2018, the following balances with such affiliates were included in the consolidated statements of financial condition in the following line items (in thousands):

(1) For pre-IPO periods, represents fees and commissions from affiliates of the Bank Stockholders.

(2) The Company maintains a market data license agreement with Refinitiv (TR in the predecessor period). Under the agreement, the Company delivers to Refinitiv certain market data feeds which Refinitiv redistributes to its customers. The Company earns license fees and royalties for these feeds.

(3) For pre-IPO periods, represents interest income from money market funds invested with and savings accounts deposited with affiliates of the Bank Stockholders.

32

(4) The Company maintains a shared services agreement with Refinitiv (TR in the predecessor period). Under the terms of the agreement, Refinitiv provides the Company with certain real estate, payroll, benefits administration, insurance, content, financial reporting and tax support.

The Company reimburses affiliates of Refinitiv (TR in the predecessor period) for expenses paid on behalf of the Company for various services including salaries and bonuses, marketing, professional fees, communications, data costs and certain other administrative services. For the three and nine months ended September 30, 2019, the Company reimbursed such affiliates approximately $1.2 million and $5.5 million, respectively, for these expenses. For the three and nine months ended September 30, 2018, the Company reimbursed such affiliates approximately $0.3 million and $28.7 million, respectively, for these expenses.

The Company is indemnified by Refinitiv for any tax liabilities that existed in the entity contributed by Refinitiv as a result of the Refinitiv Contribution.  At September 30, 2019, $2.7 million is included in other assets on the September 30, 2019 consolidated statement of financial condition related to this indemnification.

During 2014, the Company issued Class A Shares and unvested Class P-1(A) Shares to some of the Bank Stockholders as a result of a $120.0 million capital contribution.  In connection with this investment, employees invested $5.3 million in the Company and were issued Class C Shares and unvested Class P-1(C) Shares.  Certain Class P-1(A) Shares and Class P-1(C) Shares vested on July 31, 2018, based on a formula determined by the Company’s new credit platforms’ revenues and any remaining unvested Class P-1(A) Shares and Class P-1(C) Shares were cancelled and as a result  no contingent consideration has been recognized related to these shares subsequent to that date.  The Company recognized contingent consideration for the nine months ended September 30, 2018 of $26.8 million (which included a reversal of contingent consideration of $2.5 million for the three months ended September 30, 2018), relating to these shares, which is included in net revenue on the consolidated statements of income.

15.          Fair Value of Financial Instruments

Certain financial instruments that are not carried at fair value on the consolidated statements of financial condition are carried at amounts that approximate fair value. These instruments include deposits with clearing organizations and accounts receivable.

The Company's money market funds are classified within level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.

The Company has no instruments that are classified within level 2 or level 3 of the fair value hierarchy.

The fair value measurements are as follows (in thousands):

	QuotedPrices in

16.          Credit Risk

The Company may be exposed to credit risk regarding its receivables, which are primarily receivables from financial institutions, including investment managers and broker/dealers. At September 30, 2019 and December 31, 2018, the Company established an allowance for doubtful accounts of $1.3 million and $1.2 million, respectively, with regard to these receivables.

In the normal course of business the Company, as agent, executes transactions with, and on behalf of, other brokers and dealers. If the agency transactions do not settle because of failure to perform by either counterparty, the Company may be obligated to discharge the obligation of the non-performing party and, as a result, may incur a loss if the market value of the security is different from the contract amount of the transaction.

A substantial number of the Company's transactions are collateralized and executed with, and on behalf of, a limited number of brokers and dealers. The Company's exposure to credit risk associated with the nonperformance of these clients in fulfilling their contractual obligations pursuant to securities transactions can be directly impacted by volatile trading markets which may impair the clients' ability to satisfy their obligations to the Company.

From time to time, the Company enters into agreements to repurchase to facilitate the clearance of securities.  Credit exposure related to these agreements to repurchase, including the risk related to a decline in market value of collateral (pledged or received), is managed by entering into agreements to repurchase with overnight or short-term maturity dates and only entering into repurchase transactions with netting members of the Fixed Income Clearing Corporation (“FICC”). The FICC requires dealer netting members to maintain a minimum of $25 million in equity capital and $10 million in excess net capital. The FICC operates a continuous net settlement system, whereby as trades are submitted and compared the FICC becomes the counterparty. The FICC also marks to market collateral on a daily basis, requiring member firms to pay or receive margin amounts as part of their daily funds settlement.

The Company does not expect nonperformance by counterparties in the above situations. However, the Company's policy is to monitor its market exposure and counterparty risk. In addition, the Company has a policy of reviewing, as considered necessary, the credit standing of each counterparty with which it conducts business.

17.          Commitments and Contingencies

In the normal course of business, the Company enters into user agreements with its dealers which provide the dealers with indemnification from third parties in the event that the electronic marketplaces of the Company infringe upon the intellectual property or other proprietary right of a third party. The Company's exposure under these user agreements is unknown as this would involve estimating future claims against the Company which have not yet occurred. However, based on its experience, the Company expects the risk of a material loss to be remote.

The Company has been named as a defendant, along with other financial institutions, in antitrust class actions (consolidated into two actions) relating to trading practices in United States Treasury securities auctions. The Company has filed a motion to dismiss the actions, believes it has substantial defenses to the other plaintiff's claims and intends to defend itself vigorously. Additionally, the Company was dismissed from a class action relating to an interest rate swaps matter in 2017, but that matter continues against the remaining defendant financial institutions.

The Company is a co-defendant in a matter relating to the distribution of financial strength ratings over the Company's trading platform to one of its customers. The matter alleges that while certain business units of the client were licensed to receive the data via the Company's platform, the data was also distributed without authorization to certain end clients of the customer. The plaintiff claims to have suffered approximately $80 million in damages and also seeks punitive damages, attorneys' fees and costs. In September 2019, the Court dismissed some, but not all, of plaintiff’s claims, and rejected plaintiff’s damages theory on which it relied to support its claims for approximately $80 million in damages. The Company intends to continue to vigorously defend what the Company believes to be meritless claims.

The Company records its best estimate of a loss, including estimated defense costs, when the loss is considered probable and the amount of such loss can be reasonably estimated. Based on its experience, the Company believes that the amount

34

of damages claimed in a legal proceeding is not a meaningful indicator of the potential liability. At this time, the Company cannot reasonably predict the timing or outcomes of, or estimate the amount of loss, or range of loss, if any, related to its pending legal proceedings, including the matters described above, and therefore does not have any contingency reserves established for any of these matters.

Revolving Credit Facility

On April 8, 2019, the Company entered into a five year, $500 million senior secured revolving credit facility (“Credit Facility”) with a syndicate of banks. The Credit Facility provides additional borrowing capacity to be used to fund ongoing working capital needs, letters of credit and for general corporate purposes, including potential future acquisitions and expansions.

Under the terms of the credit agreement that governs the Credit Facility, borrowings under the Credit Facility bear interest at a rate equal to, at the Company’s option, either (a) a base rate equal to the greatest of (i) the administrative agent’s prime rate, (ii) the federal funds effective rate plus ½ of 1.0% and (iii) one month LIBOR plus 1.0%, in each case plus 0.75%, or (b) LIBOR plus 1.75%, subject to a 0.00% floor. The credit agreement also includes a commitment fee of 0.25% for available but unborrowed amounts and other administrative fees that are payable quarterly. The Credit Facility is available until April 2024, provided the Company is in compliance with all covenants. Financial covenant requirements include maintaining minimum ratios related to interest coverage and leverage.

As of September 30, 2019, there were no amounts outstanding under the Credit Facility.

18.          Earnings Per Share

In April 2019, the Company completed the Reorganization Transactions and the IPO, which, among other things, resulted in the Corporation becoming the successor of TWM LLC for financial reporting purposes. As a result, earnings per share information for the pre-IPO period is not comparable to earnings per share information for the post-IPO period.  Thus, earnings per share information is being presented separately for the pre-IPO and post-IPO periods.

The following table summarizes the basic and diluted earnings per share calculations for Tradeweb Markets LLC (pre-IPO period):

(1) Earnings per share and weighted average shares outstanding for the pre-IPO periods have been computed to give effect to the Reorganization Transactions, including the amendment and restatement of the TWM LLC Agreement to, among other things, (i) provide for LLC Interests and (ii) exchange all of the then existing membership interests in TWM LLC for LLC interests.

Earnings per share - Basic	$	0.21	$	0.30
Earnings per share - Diluted	$	0.20	$	0.28

For the three and nine months ended September 30, 2019, there were approximately 247,491 and 126,667 shares, respectively, underlying equity-settled PRSUs and options that were anti-dilutive and thus excluded from the computation of diluted earnings per share. For the three and nine months ended September 30, 2018, there were approximately 2,798,674 and 5,444,566 shares, respectively, related to the contingent consideration payable that were anti-dilutive and thus excluded from the computation of diluted earnings per share.

LLC Interests held by the Continuing LLC Owners are redeemable in accordance with the TWM LLC Agreement, at the election of such holders, for shares of Class A or Class B common stock of Tradeweb Markets Inc. After evaluating the potential dilutive effect under the if-converted method, the 79,289,005 LLC Interests for the assumed exchange of non-controlling interests were determined to be anti-dilutive and thus were excluded from the computation of diluted earnings per share for the post-IPO periods.

Shares of Class C and Class D common stock do not have economic rights in Tradeweb Markets Inc. and, therefore, are not participating securities for purposes of the computation of earnings per share.

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

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10‑Q. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from the results described in or implied by the forward-looking statements. Factors that could cause or contribute to those differences include, but are not limited to, those identified below and those discussed in the section titled “Cautionary Note Regarding Forward-Looking Statements” included elsewhere in this Quarterly Report on Form 10‑Q.

Overview

We are a leader in building and operating electronic marketplaces for our global network of clients across the financial ecosystem. Our network is comprised of clients across the institutional, wholesale and retail client sectors, including many of the largest global asset managers, hedge funds, insurance companies, central banks, banks and dealers, proprietary trading firms and retail brokerage and financial advisory firms as well as regional dealers. Our marketplaces facilitate trading across a range of asset classes, including rates, credit, equities and money markets. We are a global company serving clients in over 65 countries with offices in North America, Europe and Asia. We believe our proprietary technology and culture of collaborative innovation allow us to adapt our offerings to enter new markets, create new platforms and solutions and adjust to regulations quickly and efficiently. We support our clients by providing solutions across the trade lifecycle, including pre-trade, execution, post-trade and data.

Our institutional client sector serves institutional investors in over 40 markets across 25 currencies, and in over 65 countries around the globe. We connect institutional investors with pools of liquidity using our flexible order and trading systems. Our clients trust the integrity of our markets and recognize the value they get by trading electronically: enhanced transparency, competitive pricing, efficient trade execution and regulatory compliance.

In our wholesale client sector, we provide a broad range of electronic, voice and hybrid platforms to more than 300 dealers and financial institutions with more than 90 actively trading on our electronic or hybrid markets with our Dealerweb platform. This platform was launched in 2008 following the acquisition of inter-dealer broker Hilliard Farber & Co., Inc. In 2011, we acquired the brokerage assets of Rafferty Capital Markets. Today, Dealerweb actively competes across a range of rates, credit, derivatives and equity markets.

In our retail client sector, we provide advanced trading solutions for financial advisory firms and traders with our Tradeweb Direct platform. We entered the retail sector in 2006 and launched our Tradeweb Direct platform following the 2013 acquisition of BondDesk Group LLC, which was built to bring innovation and efficiency to the wealth management community. Tradeweb Direct has provided financial advisory firms access to live offerings, accurate pricing in the marketplace and fast execution.

Our markets are large and growing. Electronic trading continues to increase across the markets in which we operate as a result of market demand for greater transparency, higher execution quality, operational efficiency and lower costs, as well as regulatory changes. We believe our deep client relationships, asset class breadth, geographic reach, regulatory knowledge and scalable technology position us to continue to be at the forefront of the evolution of electronic trading. Our platforms provide transparent, efficient, cost-effective and compliant trading solutions across multiple products, regions and regulatory regimes. As market participants seek to trade across multiple asset classes, reduce their costs of trading and increase the effectiveness of their trading, including through the use of data and analytics, we believe the demand for our platforms and electronic trading solutions will continue to grow.

Trends and Other Factors Impacting Our Performance

Economic Environment

Our business is impacted by the overall market activity and, in particular, trading volumes and market volatility. Lower volatility is correlated to lower liquidity, which may result in lower trading volume for our clients and may negatively impact our operating performance. As a result, our business is sensitive to slow trading environments and the continuity of conservative monetary policies of central banks internationally, which tend to lessen volatility.

While our business is impacted by the overall activity of the market and market volatility, our revenues consist of a mix of fixed and variable fees that partially mitigates this impact. More importantly, we are actively engaged in the further electronification of trading activities, which will help mitigate this impact as we believe secular growth trends can partially offset market volatility risk.

Regulatory Environment

Our business is subject to extensive regulations in the United States and internationally, which may expose us to significant regulatory risk and cause additional legal costs to ensure compliance. The existing legal framework that governs the financial markets is periodically reviewed and amended, resulting in enforcement of new laws and regulations that apply to our business. The current regulatory environment in the United States may be subject to future legislative changes driven by the current presidential administration. The impact of any reform efforts on us and our operations remains uncertain. In addition, as a result of the referendum in favor of the United Kingdom’s withdrawal from the European Union (“Brexit”) in June 2016, which is currently scheduled to occur on January 31, 2020, we have incurred additional costs to address the potential effects of Brexit, including costs associated with establishing a new regulated subsidiary in the Netherlands. Compliance with regulations may require us to dedicate additional financial and operational resources, which may adversely affect our profitability. In addition, compliance with regulations may require our clients to dedicate significant financial and operational resources, which may negatively affect their ability to pay our fees and use our platforms and, as a result, our profitability. However, under certain circumstances regulation may increase demand for our platforms and solutions, and we believe we are well positioned to benefit from any potential increased electronification due to regulatory changes as market participants seek platforms that meet regulatory requirements and solutions that help them comply with their regulatory obligations. For example, our 2018 revenue increased due in part to higher trading volumes as a result of, and the introduction of our new Approved Publication Arrangement (“APA”) service in connection with, the implementation of Markets in Financial Instruments Directive II (“MiFID II”) in January 2018.

Competitive Environment

We and our competitors compete to introduce innovations in market structure and new electronic trading capabilities. While we endeavor to be a leader in innovation, new trading capabilities of our competitors are also adopted by market participants. On the one hand, this increases liquidity and electronification for all participants, but it also puts pressure on us to further invest in our technology and to innovate to ensure the continued growth of our network of clients and continued improvement of liquidity, electronic processing and pricing on our platforms. Our ability to compete is influenced by key factors such as (i) developments in trading platforms and solutions, (ii) the liquidity we provide on transactions, (iii) the transaction costs we incur in providing our solutions, (iv) the efficiency in execution of transactions on our platforms, (v) our ability to hire and retain talent and (vi) our ability to maintain the security of our platforms and solutions. Our competitive position is also influenced by the familiarity and integration of our clients with our electronic, voice and hybrid systems. When either a client wants to trade in a new product or we want to introduce a new product, trading protocol or other solution, we believe we benefit from our clients’ familiarity with our offerings as well as our integration into their order management systems and back offices.

Technology and Cybersecurity Environment

Our business and its success are largely impacted by the introduction of increasingly complex and sophisticated technology systems and infrastructures and new business models. Offering specialized trading venues and solutions

40

through the development of new and enhanced platforms is essential to maintaining our level of competitiveness in the market and attracting new clients seeking platforms that provide advanced automation and better liquidity. We believe we will continue to increase demand for our platforms and solutions and the volume of transactions on our platforms, and thereby enhance our client relationships, by responding to new trading and information requirements by utilizing technological advances and emerging industry standards and practices in an effective and efficient way. We plan to continue to focus on technology infrastructure initiatives and continually improve our platforms and solutions to further enhance our market position. We experience cyber-threats and attempted security breaches. If these were successful, these cyber security incidents could impact revenue and operating income and increase costs. We therefore continue to make investments, which may result in increased costs, to strengthen our cybersecurity measures.

Foreign Currency Exchange Rate Environment

We earn revenues, pay expenses, hold assets and incur liabilities in currencies other than the U.S. dollar. Accordingly, fluctuations in foreign currency exchange rates can affect our results of operations from period to period. In particular, fluctuations in exchange rates for non-U.S. dollar currencies may reduce the U.S. dollar value of revenues, earnings and cash flows we receive from non-U.S. markets, increase our operating expenses (as measured in U.S. dollars) in those markets, negatively impact our competitiveness in those markets or otherwise adversely impact our results of operations or financial condition. Future fluctuations of foreign currency exchange rates and their impact on our results of operations and financial condition are inherently uncertain. As we continue to grow the size of our global operations, these fluctuations may be material. See Item 3, “Quantitative and Qualitative Disclosures About Market Risk— Foreign Currency and Derivative Risk” elsewhere in this Quarterly Report on Form 10‑Q.

Effect of Pushdown Accounting on our Financial Statements

As a result of the Refinitiv Transaction, and the application of pushdown accounting, our assets and liabilities were adjusted to their estimated fair values as of October 1, 2018, the closing date of the Refinitiv Transaction. These adjusted valuations resulted in an increase in depreciation and amortization expense, due to the increased carrying value of our assets and the related increase in depreciation of tangible assets and amortization of our intangible assets, and a decrease in occupancy expense as a result of the recognition of a leasehold interest liability. Additionally, the excess of the portion of the total purchase price of the Refinitiv Transaction attributable to the purchase of our assets and liabilities over their estimated fair value as of the closing date of the Refinitiv Transaction was allocated to goodwill. Goodwill is subject to annual impairment testing. Amounts allocated to intangible assets with definite lives are subject to amortization over the estimated useful life of the asset. See Note 3 – Pushdown Accounting to our unaudited consolidated financial statements included elsewhere in this Quarterly Report on Form 10‑Q and “— Critical Accounting Policies and Estimates — Pushdown Accounting.”

Due to the change in the basis of accounting resulting from the application of pushdown accounting, the financial information for the period beginning on October 1, 2018, and through and including September 30, 2019, which we refer to as the “Successor period,” and the financial information for the periods prior to, and including, September 30, 2018, which we refer to as the “Predecessor period,” are not necessarily comparable. As discussed above, the new basis of accounting primarily impacted the values of our long-lived and indefinite-lived intangible assets and resulted in increased depreciation and amortization expense and decreased occupancy expense. However, the change in basis resulting from the Refinitiv Transaction and the application of pushdown accounting did not impact revenues, employee compensation and benefits expense, general and administrative expense, technology and communications expense or professional fees. For all other metrics, to the extent that the change in basis had a material impact on our results, we have disclosed such impact under “—Results of Operations.”

Taxation and Public Company Expenses

In connection with the Reorganization Transactions, we became the sole manager of TWM LLC. As a result, beginning with the second quarter of 2019, we became subject to U.S. federal, state and local income taxes with respect to our allocable share of any taxable income of TWM LLC and are taxed at prevailing corporate tax rates. Our actual effective tax rate is impacted by our ownership share of TWM LLC, which will increase over time as the Continuing LLC Owners redeem or exchange their LLC Interests for shares of Class A common stock or Class B common stock, as

41

applicable, or we purchase LLC Interests from the Continuing LLC Owners. In addition to tax expenses, we also incur expenses related to our operations. Furthermore, in connection with the IPO, we entered into the Tax Receivable Agreement pursuant to which we will be required to make payments that we expect to be significant. We intend to cause TWM LLC to make distributions in an amount sufficient to allow us to pay our tax obligations, operating expenses, including payments under the Tax Receivable Agreement, and our quarterly cash dividends, as and when declared by our board of directors.

In addition, as a public company, we have started to implement additional procedures and processes for the purpose of addressing the standards and requirements applicable to public companies. In particular, we expect our accounting, legal and personnel-related expenses and directors’ and officers’ insurance costs to continue to increase as we establish more comprehensive compliance and governance functions, establish, maintain and review internal controls over financial reporting in accordance with the Sarbanes-Oxley Act and prepare and distribute periodic reports in accordance with SEC rules. Beginning in the second quarter of 2019, our  financial statements reflect the impact of these expenses.

Components of our Results of Operations

Revenues

Our gross revenue is derived primarily from transaction fees, subscription fees, commissions and market data fees. For the three and nine months ended September 30, 2018, our gross revenue is offset by contingent consideration recognized as a contra-revenue adjustment related to the achievement of specific revenue earnout milestones, as further described below. This contingent consideration vested on, and has no additional impacts on our results of operations after, July 31, 2018. We believe that gross revenue is the key driver of our operating performance and therefore is the revenue measure we utilize to assess our business on a period by period basis.

Transaction Fees

We earn transaction fees from transactions executed on our trading platforms through various fee plans. Transaction fees are generated on both a variable and fixed price basis and vary by geographic region, product type and trade size. For most of our products, clients pay both fixed minimum monthly transaction fees and variable transaction fees on a per transaction basis in excess of the monthly minimum. For certain of our products, clients also pay a subscription fee in addition to the minimum monthly transaction fee. For other products, instead of a minimum monthly transaction fee, clients pay a subscription fee and variable or fixed transaction fees on a per transaction basis. For variable transaction fees, we charge clients fees based on the mix of products traded and the volume of transactions executed. Transaction volume is determined by using either a measure of the notional volume of the products traded or a count of the number of trades. We typically charge higher fees for products that are less actively traded. In addition, because transaction fees are sometimes subject to fee plans with tiered pricing based on product mix, volume, monthly minimums and monthly maximum fee caps, average transaction fees per million generated for a client may vary each month depending on the mix of products and volume traded. Furthermore, because transaction fees vary by geographic region, product type and trade size, our revenues may not correlate with volume growth.

Subscription Fees

We earn subscription fees primarily for granting clients access to our markets for trading and market data. For a limited number of products, we only charge subscription fees and no transaction fees. Subscription fees are generally generated on a fixed price basis.

For purposes of our discussion of our results of operations, we include Refinitiv (formerly Thomson Reuters) market data fees in subscription fees. We earn fixed license fees from our market data license agreement with Refinitiv. We also earn royalties from Refinitiv for referrals of new Eikon (a Refinitiv data platform) customers based on customer conversion rates. Royalties may fluctuate from period to period depending on the numbers of customer conversions achieved by Refinitiv during the applicable royalty fee earning period, which is typically five years from the date of the initial referral.

42

Commissions

We earn commission revenue from our electronic and voice brokerage services on a riskless principal basis. Riskless principal revenues are derived on matched principal transactions where revenues are earned on the spread between the buy and sell price of the transacted product. For TBA-MBS, U.S. treasury and repurchase agreement transactions executed by our wholesale clients, we also generate revenue from fixed commissions that are generally invoiced monthly.

Contingent Consideration

In 2014, we issued Class A Shares and unvested Class P1‑(A) Shares to some of the Bank Stockholders as a result of a $120.0 million capital contribution to facilitate our expansion into new credit products. In connection with this investment, certain employees also invested $5.3 million in us and were issued Class C Shares and unvested Class P1‑(C) Shares. The Class P1‑(A) Shares vested on July 31, 2018 upon the achievement of specific revenue earnout milestones related to the growth of specified credit products (the “Credit Initiative Earnout”). Prior to the July 31, 2018 vesting, we recognized contingent consideration with respect to the Credit Initiative Earnout as a contra-revenue adjustment, which partially offset gross revenue for the three and nine months ended September 30, 2018. See “— Critical Accounting Policies and Estimates — Contingent Consideration” for a discussion of the calculation of contingent consideration. The value of the contingent consideration of $156.2 million was finalized and contributed to members’ capital or employee equity compensation payable on July 31, 2018 and we therefore no longer recognize any contra-revenue adjustments from the Credit Initiative Earnout subsequent to that date. In connection with the Reorganization Transactions, the Class A Shares, Class P1-(A) Shares, Class C Shares and Class P1-(C) Shares were exchanged for LLC Interests.

Operating Expenses

Employee Compensation and Benefits

Employee compensation and benefits expense consists of wages, employee benefits, bonuses, commissions, stock-based compensation cost and related taxes. Factors that influence employee compensation and benefits expense include revenue and earnings growth, hiring new employees and trading activity which generates broker commissions. We expect employee compensation and benefits expense to increase as we hire additional employees and as our revenues and earnings grow. As a result, employee compensation and benefits can vary from period to period.

Depreciation and Amortization

Depreciation and amortization expense consists of costs relating to the depreciation and amortization of other intangible assets, acquired and internally developed software, leasehold improvements, furniture and equipment. As discussed in “— Effect of Pushdown Accounting on our Financial Statements,” we applied pushdown accounting as a result of the Refinitiv Transaction and therefore depreciation and amortization expense in Successor reporting periods will differ from amounts reported in Predecessor periods.

General and Administrative

General and administrative expense consists of travel and entertainment, marketing, value-added taxes, state use taxes, foreign currency transaction gains and losses, charitable contributions, other administrative expenses and bad debt expense. We expect general and administrative expense to increase as we expand the number of our employees and product offerings and grow our operations.

Technology and Communications

Technology and communications expense consists of costs relating to software and hardware maintenance, our internal network connections, data center costs, clearance costs and data feeds provided by third-party service providers,

43

including Refinitiv pursuant to a shared services agreement. Factors that influence technology and communications expense include the growth of our client base and product offerings.

Professional Fees

Professional fees consist primarily of accounting, tax and legal fees and fees paid to technology and software consultants to maintain our trading platforms and infrastructure. Accounting, tax and legal fees are expected to grow as a result of the changes in our structure and operations that we will continue to implement as a public company. Factors that influence technology and software consulting expense include the growth of our client base and product offerings.

Occupancy

Occupancy expense consists of operating lease rent and related costs for office space and data centers leased in North America, Europe and Asia. Fees incurred by us under a shared services agreement with Refinitiv for office space are also included in occupancy expense. We expect occupancy expense to increase as we expand the number of our employees and grow our operations. As discussed in “— Effect of Pushdown Accounting on our Financial Statements,” we applied pushdown accounting as a result of the Refinitiv Transaction and therefore occupancy expense in Successor reporting periods will differ from amounts reported in Predecessor periods.

Net Interest Income (Expense)

Interest income consists of interest earned from our cash deposited with large commercial banks and money market funds. Beginning with the second quarter of 2019, interest expense consists of commitment fees payable on, and, if applicable, interest payable on any borrowings outstanding under, the Revolving Credit Facility.

Income Taxes

Beginning with the second quarter of 2019, we became subject to U.S. federal, state and local income taxes with respect to our taxable income, including our allocable share of any taxable income of TWM LLC, and are taxed at prevailing corporate tax rates. TWM LLC is a multiple member limited liability company taxed as a partnership and accordingly any taxable income generated by TWM LLC is passed through to and included in the taxable income of its members, including us, on a pro rata basis. Income taxes also include unincorporated business taxes on income earned or losses incurred for conducting business in certain state and local jurisdictions, income taxes on income earned or losses incurred in foreign jurisdictions on certain operations and federal and state income taxes on income earned or losses incurred, both current and deferred, on subsidiaries that are taxed as corporations for U.S. tax purposes.

Overview

During the three months ended September 30, 2019, our business was impacted by a number of factors, including higher client trading activity, driving revenue increases in rates, credit, equities and money markets trading. Our market data business also grew due to the expansion of our market data license agreement with Refinitiv. Our expenses were impacted by higher depreciation and amortization expense as a result of the application of pushdown accounting and non-cash stock-based compensation expense related to options.

Gross revenue increased by $35.7 million or 21.6% to $201.0 million for the three months ended September 30, 2019 from $165.3 million for the three months ended September 30, 2018. This increase in gross revenue was mainly due to higher trading volumes resulting in a $20.2 million increase in transaction fees and a $13.2 million increase in commission revenue. Net revenue increased by $33.2 million or 19.8% to $201.0 million for the three months ended September 30, 2019 from $167.8 million for the three months ended September 30, 2018. Non-cash contingent consideration decreased by $2.5 million for the three months ended September 30, 2019 as a result of the vesting of the Credit Initiative Earnout at July 31, 2018, and the related reduction in the actual consideration versus the estimated consideration.

Total expenses for the three months ended September 30, 2019 and 2018 were $142.7 million and $115.0 million, respectively. Total expenses for the three months ended September 30, 2019 were impacted by higher depreciation and amortization expense as a result of the application of pushdown accounting, and higher employee compensation and benefits expense, including the impact of non-cash stock-based compensation expense related to options. Total expenses for the three months ended September 30, 2019 were partially offset by lower general and administrative costs, specifically foreign exchange gains.

Income before taxes for the three months ended September 30, 2019 and 2018 was $58.9 million and $53.5 million, respectively. Net income for the three months ended September 30, 2019 and 2018 was $48.6 million and $46.0 million, respectively. Net income attributable to Tradeweb Markets Inc. for the three months ended September 30, 2019 was $29.6 million. Income before taxes, net income and net income attributable to Tradeweb Markets Inc. for the three

45

months ended September 30, 2019 were impacted by higher net revenue of $33.2 million, partially offset by higher depreciation and amortization expense as a result of the application of pushdown accounting, resulting in a $18.3 million increase in depreciation and amortization expense, and higher employee compensation and benefits expense of $10.6 million, including $2.0 million of non-cash stock-based compensation expense related to options.

Components of gross revenue growth:

(1) Subscription fees for the three months ended September 30, 2019 and 2018 include $13.3 million and $12.5 million, respectively, of Refinitiv (formerly Thomson Reuters) market data fees.

(2) Constant currency growth, which is a non-GAAP financial measure, is defined as gross revenue growth excluding the effects of foreign currency fluctuations. Gross revenue excluding the effects of foreign currency fluctuations is calculated by translating the current period and prior period’s gross revenue using the average exchange rates for 2018. We use constant currency growth as a supplemental metric to evaluate our underlying gross revenue performance between periods by removing the impact of foreign currency fluctuations. We believe that providing constant currency growth provides a useful comparison of our gross revenue performance and trends between periods.

Our variable and fixed revenues by fee type for the three months ended September 30, 2019 and 2018, and the resulting dollar and percentage changes, were as follows:

Transaction fees. Transaction fees increased by $20.2 million or 21.8% to $112.8 million for the three months ended September 30, 2019 from $92.6 million for the three months ended September 30, 2018 primarily due to higher trading volumes for rates derivatives products and ETFs.

Subscription fees. Subscription fees increased by $2.9 million or 6.5% to $48.6 million for the three months ended September 30, 2019 from $45.7 million for the three months ended September 30, 2018 primarily due to higher Institutional MBS, retail and market data fees.

Commissions.  Commission revenue increased by $13.2 million or 54.1% to $37.6 million for the three months ended September 30, 2019 from $24.4 million for the three months ended September 30, 2018 primarily due to higher trading volumes for U.S. corporate bonds and U.S. treasuries.

Other. Other revenue decreased by $0.6 million or (22.4)% to $2.0 million for the three months ended September 30, 2019 from $2.6 million for the three months ended September 30, 2018 primarily as a result of lower fees from a third party for certain licensing and development in Canada.

Contingent consideration. There was no contingent consideration for the three months ended September 30, 2019 due to the vesting of the Credit Initiative Earnout at July 31, 2018. Contingent consideration for the three months ended September 30, 2018 was $(2.5) million.

Institutional. Revenues from our Institutional client sector increased by $23.4 million or 24.0% to $120.9 million for the three months ended September 30, 2019 from $97.5 million for the three months ended September 30, 2018. The increase was derived primarily from higher trading volumes for rates derivatives products, mortgages products and ETFs, partially offset by the impact of foreign exchange, mainly the weakening of the euro.

Wholesale. Revenues from our Wholesale client sector increased by $8.9 million or 26.0% to $43.0 million for the three months ended September 30, 2019 from $34.2 million for the three months ended September 30, 2018. The increase was derived primarily from higher trading volumes for U.S. session-based trading and U.S. treasuries.

Retail. Revenues from our Retail client sector increased by $2.4 million or 13.2% to $20.2 million for the three months ended September 30, 2019 from $17.8 million for the three months ended September 30, 2018. The increase was primarily due to higher trading volumes for certificates of deposit partially offset by lower revenues for software development and implementation.

Market Data. Revenues from our Market Data client sector increased by $1.1 million or 7.3% to $16.9 million for the three months ended September 30, 2019 from $15.8 million for the three months ended September 30, 2018 primarily as a result of increased Refinitiv (formerly Thomson Reuters) license fees due to an increase in the number of market data feeds provided to Refinitiv.

Rates. Revenues from our Rates asset class increased by $22.9 million or 24.7% to $115.5 million for the three months ended September 30, 2019 from $92.6 million for the three months ended September 30, 2018 primarily due to higher trading volumes for derivatives products, U.S. treasuries and mortgages products.

Credit. Revenues from our Credit asset class increased by $5.9 million or 17.6% to $39.6 million for the three months ended September 30, 2019 from $33.7 million for the three months ended September 30, 2018 primarily due to higher trading volumes for U.S. corporate bonds and credit derivatives products.

Equities. Revenues from our Equities asset class increased by $3.8 million or 45.4% to $12.3 million for the three months ended September 30, 2019 from $8.5 million for the three months ended September 30, 2018 primarily due to higher trading volumes for ETFs and equity derivatives products.

Money Markets. Revenues from our Money Markets asset class increased by $1.8 million or 20.9% to $10.5 million for the three months ended September 30, 2019 from $8.7 million for the three months ended September 30, 2018 primarily due to increased volumes for repurchase agreements and certificates of deposit.

Market Data. Revenues from Market Data increased by $1.1 million or 7.3% to $16.9 million for the three months ended September 30, 2019 from $15.8 million for the three months ended September 30, 2018 primarily as a result of increased Refinitiv (formerly Thomson Reuters) license fees due to an increase in the number of market data feeds provided to Refinitiv.

Other Fees. Revenues from Other Fees increased by $0.1 million or 1.2% to $6.2 million for the three months ended September 30, 2019 from $6.1 million for the three months ended September 30, 2018 primarily due to the timing of Retail revenues for software development and implementation partially offset by lower fees from a third party for certain licensing and development in Canada.

A significant percentage of our revenues are tied directly to overall trading volumes in the rates, credit, equities and money markets asset classes. The average daily volumes and total volumes on our trading platforms by asset class for the three months ended September 30, 2019 and 2018 were as follows:

	Three Months Ended
	September 30, 2019				September 30, 2018				ADV
	ADV		Volume		ADV		Volume		% Change
	(dollars in millions)
Rates	$	563,379	$	36,305,114	$	342,572	$	21,710,832	64.5	%
Credit		17,199		1,117,045		11,885		760,207	44.7	%
Equities		7,345		476,129		5,746		366,590	27.8	%
Money Markets		227,125		14,701,122		171,509		10,872,806	32.4	%
Total	$	815,048	$	52,599,410	$	531,712	$	33,710,435	53.3	%

We believe the increases in average daily volumes in the three months ended September 30, 2019 for most asset classes can be attributed to various factors, including further electronification of trading activities across our asset classes, increase in market share, new products, new clients and increased volatility. Trading activity in both long and short-tenor interest rate swaps and swaptions, repurchase agreements and mortgages were the leading drivers of our overall volume growth year-over-year. Rates ADV increased mainly due to higher trading activity in both long and short-tenor interest rate swaps and swaptions, as well as mortgages and U.S. treasuries. Credit ADV increased due mainly to higher trading activity in credit derivatives, U.S. high-grade and high-yield credit as well as Chinese bonds. Equities ADV increased due mainly to higher trading activity in institutional ETFs. Money Markets ADV increased due to the continued growth of bilateral electronic trading in repurchase agreements.

The average variable fees per million dollars of volume traded on our trading platforms by asset class for the three months ended September 30, 2019 and 2018 are summarized below. There are four potential drivers of quarterly fluctuations in our average variable fees per million: (1) volume discounts, (2) the mix of cash and derivatives products traded, (3) the mix of protocols underpinning cash and derivatives products and (4) pricing. Average variable fees per million should be reviewed in conjunction with our trading volumes and gross revenue by asset class. Since variable fees are sometimes subject to fee plans with tiered pricing based on product mix and volume, average variable fees per million for a specific asset class may not correlate with volumes or revenue growth. For example, average variable fees per million dollars of volume for our Credit asset class decreased 17.7% for the three months ended September 30, 2019 while gross revenue for our Credit asset class increased 17.6% over the same period.

Rates average variable fees per million was impacted by the growth of short tenor swap volumes, a product which has a lower variable fee capture as compared to other rates products. Credit average variable fees per million was impacted by a mix shift due to higher growth in credit derivatives volumes, products which have a lower variable fee capture as compared to cash credit products, and a decline in municipals volumes. Equities average variable fees per

million was impacted by a mix shift towards Institutional European ETFs and away from Wholesale products. Money Markets average variable fees per million was impacted by a mix shift within repurchase agreements volumes from Wholesale to Institutional.

Revenues from International clients increased by $16.1 million or 27.6% to $74.4 million for the three months ended September 30, 2019 from $58.3 million for the three months ended September 30, 2018 primarily due to higher trading volumes for European interest rate swaps, European ETFs, U.S. dollar-denominated swaps and European repurchase agreements. Fluctuations in foreign currency rates decreased our International gross revenue by $3.6 million.

Total Expenses	$	142,723	$	114,973

Employee Compensation and Benefits. Employee compensation and benefits expense increased by $10.6 million or 15.3% to $79.6 million for the three months ended September 30, 2019 from $69.1 million for the three months ended September 30, 2018. The increase was primarily due to a $3.7 million increase in salaries and benefits, due to an increase in employee headcount, a $3.0 million increase in commission related expenses due to higher Wholesale revenues, $2.6 million increase in annual incentive compensation expenses tied to operating performance, and a $2.0 million increase in non-cash stock-based compensation expense related to options. Total employee headcount increased to 926 as of September 30, 2019 from 896 as of September 30, 2018.

Depreciation and Amortization. Depreciation and amortization expense for the three months ended September 30, 2019 was $35.1 million. Depreciation and amortization expense for the three months ended September 30, 2018 was

50

$16.4 million. As a result of the Refinitiv Transaction and the application of pushdown accounting, we adjusted our assets and liabilities to their estimated fair values as of October 1, 2018, which resulted in an increase in depreciation of tangible assets and amortization of our intangible assets. The impact of such adjustments increased depreciation and amortization expense during the three months ended September 30, 2019 by $18.3 million.

Technology and Communications. Technology and communications expense increased by $0.4 million or 4.6% to $9.5 million for the three months ended September 30, 2019 from $9.1 million for the three months ended September 30, 2018. The increase was primarily due to increased clearance fees as a result of higher trading volumes.

General and Administrative. General and administrative expense decreased by $1.9 million or (20.0)% to $7.5 million for the three months ended September 30, 2019 from $9.4 million for the three months ended September 30, 2018. The decrease was primarily a result of an increase in foreign exchange gains of $1.5 million.

Professional Fees. Professional fees decreased by $0.3 million or (3.6)% to $7.3 million for the three months ended September 30, 2019 from $7.6 million for the three months ended September 30, 2018. The decrease was primarily due to fees incurred in 2018 associated with preliminary work related to our IPO.

Occupancy. Occupancy expense for the three months ended September 30, 2019 was $3.6 million.  Occupancy expense for the three months ended September 30, 2018 was $3.5 million. As a result of the Refinitiv Transaction and the application of pushdown accounting, at October 1, 2018, we established a leasehold interest liability, which resulted in a $0.1 million increase in occupancy expense during the three months ended September 30, 2019.

Net Interest Income (Expense)

Net interest income (expense) decreased by $0.1 million to net interest income of $0.6 million for the three months ended September 30, 2019 from net interest income of $0.7 million for the three months ended September 30, 2018 due to higher interest income offset by credit facility fees related to the Revolving Credit Facility.

Income Taxes

Provision for income taxes for the three months ended September 30, 2019 was $10.3 million. Provision for income taxes for the three months ended September 30, 2018 was $7.5 million. The provision for income taxes for the three months ended September 30, 2019 was impacted by the Reorganization Transactions and the IPO, which resulted in Tradeweb Markets Inc. becoming subject to U.S. federal, state and local income taxes with respect to its taxable income, including its allocable share of any taxable income of TWM LLC, and being taxed at prevailing corporate tax rates. Prior to the Reorganization Transactions, income taxes consisted only of business taxes incurred by TWM LLC and certain subsidiaries for business conducted in certain state, local and foreign jurisdictions as well as federal, state and local taxes for certain subsidiaries that are taxed as corporations for U.S. tax purposes.

Overview

During the nine months ended September 30, 2019, our business was impacted by a number of factors, including higher client trading activity, driving revenue increases in rates, credit, equities and money markets trading. Our market data business also grew due to the expansion of our market data license agreement with Refinitiv. Our expenses were impacted by higher depreciation and amortization expense as a result of the application of pushdown accounting and non-cash stock-based compensation expense related to the Special Option Award (as defined below) as a result of the completion of the IPO during the second quarter of 2019, and post-IPO options awarded in the third quarter of 2019.

Gross revenue increased by $72.5 million or 14.3% to $578.3 million for the nine months ended September 30, 2019 from $505.8 million for the nine months ended September 30, 2018. This increase in gross revenue was mainly due to higher trading volumes resulting in a $45.6 million increase in transaction fees and a $28.4 million increase in commissions. Net revenue increased by $99.3 million or 20.7% to $578.3 million for the nine months ended September 30, 2019 from $478.9 million for the nine months ended September 30, 2018. Non-cash contingent consideration decreased by $26.8 million for the nine months ended September 30, 2019 as a result of the vesting of the Credit Initiative Earnout at July 31, 2018.

Total expenses for the nine months ended September 30, 2019 and 2018 were $442.8 million, and $338.6 million, respectively. Total expenses for the nine months ended September 30, 2019 were impacted by higher depreciation and amortization expense as a result of the application of pushdown accounting and higher employee compensation and benefits expense, including the impact of non-cash stock-based compensation expense related to the Special Option Award, which, as a result of the completion of the IPO, we began to expense during the second quarter of 2019, and post-IPO options awarded in the third quarter of 2019.

Income before taxes for the nine months ended September 30, 2019 and 2018 was $137.2 million and $142.1 million, respectively. Net income for the nine months ended September 30, 2019 and 2018 was $115.8 million and $130.2 million, respectively. Net income attributable to Tradeweb Markets Inc. for the nine months ended September 30,

52

2019 was $42.4 million. Income before taxes, net income and net income attributable to Tradeweb Markets Inc. for the nine months ended September 30, 2019 were negatively impacted by higher depreciation and amortization expense as a result of the application of pushdown accounting, resulting in a $52.5 million increase in depreciation and amortization expense and $22.4 million of stock-based compensation expense related to the Special Option Award and post-IPO options awarded in 2019, partially offset by higher revenues.

(1) Subscription fees for the nine months ended September 30, 2019 and 2018 include $40.3 million and $36.8 million, respectively, of Refinitiv (formerly Thomson Reuters) market data fees.

(2) Constant currency growth, which is a non-GAAP financial measure, is defined as gross revenue growth excluding the effects of foreign currency fluctuations. Gross revenue excluding the effects of foreign currency fluctuations is calculated by translating the current period and prior period’s gross revenue using the average exchange rates for 2018. We use constant currency growth as a supplemental metric to evaluate our underlying gross revenue performance between periods by removing the impact of foreign currency fluctuations. We believe that providing constant currency growth provides a useful comparison of our gross revenue performance and trends between periods.

Transaction fees. Transaction fees increased by $45.6 million or 16.7% to $319.3 million for the nine months ended September 30, 2019 from $273.8 million for the nine months ended September 30, 2018 primarily due to higher trading volumes for rates derivatives products and ETFs.

Subscription fees. Subscription fees increased by $0.7 million or 0.5% to $144.7 million for the nine months ended September 30, 2019 from $144.0 million for the nine months ended September 30, 2018 primarily due to higher market data and Institutional MBS fees, partially offset by lower Retail fees.

Commissions.  Commission revenue increased by $28.4 million or 35.5% to $108.2 million for the nine months ended September 30, 2019 from $79.8 million for the nine months ended September 30, 2018 primarily due to higher trading volumes for U.S. corporate bonds and U.S. treasuries.

Other. Other revenue decreased by $2.1 million or (26.1)% to $6.1 million for the nine months ended September 30, 2019 from $8.2 million for the nine months ended September 30, 2018 primarily as a result of lower fees from a third party for certain licensing and development in Canada.

Revenues from our Institutional client sector increased by $39.2 million or 13.0% to $341.2 million for the nine months ended September 30, 2019 from $301.9 million for the nine months ended September 30, 2018. The increase was derived primarily from higher trading volumes for rates derivatives products, ETFs and mortgages products, partially offset by the impact of foreign exchange, mainly the weakening of the euro.

Wholesale. Revenues from our Wholesale client sector increased by $25.4 million or 25.6% to $124.4 million for the nine months ended September 30, 2019 from $99.0 million for the nine months ended September 30, 2018. The increase was derived primarily from higher trading volumes for U.S. session-based trading and U.S. treasuries.

Retail. Revenues from our Retail client sector increased by $3.5 million or 6.1% to $61.3 million for the nine months ended September 30, 2019 from $57.8 million for the nine months ended September 30, 2018. The increase was derived primarily from higher trading volumes for certificates of deposit, municipal bonds and U.S. treasuries partially offset by lower revenues for software development and implementation.

Market Data. Revenues from our Market Data client sector increased by $4.3 million or 9.1% to $51.4 million for the nine months ended September 30, 2019 from $47.1 million for the nine months ended September 30, 2018 primarily as a result of increased Refinitiv (formerly Thomson Reuters) license fees due to an increase in the number of market data feeds provided to Refinitiv.

Rates. Revenues from our Rates asset class increased by $45.0 million or 16.0% to $326.7 million for the nine months ended September 30, 2019 from $281.6 million for the nine months ended September 30, 2018 primarily due to higher trading volumes for derivatives products, U.S. treasuries and mortgages products.

Credit. Revenues from our Credit asset class increased by $16.2 million or 15.8% to $118.6 million for the nine months ended September 30, 2019 from $102.5 million for the nine months ended September 30, 2018 primarily due to higher trading volumes for U.S. corporate bonds .

Equities. Revenues from our Equities asset class increased by $6.9 million or 24.3% to $35.2 million for the nine months ended September 30, 2019 from $28.3 million for the nine months ended September 30, 2018 primarily due to higher trading volumes for ETFs.

Money Markets. Revenues from our Money Markets asset class increased by $5.1 million or 20.3% to $30.4 million for the nine months ended September 30, 2019 from $25.3 million for the nine months ended September 30, 2018 primarily due to higher trading volumes for repurchase agreements and certificates of deposit.

Market Data. Revenues from Market Data increased by $4.3 million or 9.1% to $51.4 million for the nine months ended September 30, 2019 from $47.1 million for the nine months ended September 30, 2018 primarily as a result of

55

increased Refinitiv (formerly Thomson Reuters) license fees due to an increase in the number of market data feeds provided to Refinitiv.

Other Fees. Revenues from Other Fees decreased by $5.0 million or (23.8)% to $16.0 million for the nine months ended September 30, 2019 from $21.0 million for the nine months ended September 30, 2018 primarily due lower fees from a third party for certain licensing and development in Canada and lower Retail revenues for software development and implementation.

A significant percentage of our revenues are tied directly to overall trading volumes in the rates, credit, equities and money markets asset classes. The average daily volumes and total volumes on our trading platforms by asset class for the nine months ended September 30, 2019 and 2018 were as follows:

	Nine Months Ended
	September 30, 2019				September 30, 2018				ADV
	ADV		Volume		ADV		Volume		% Change
	(dollars in millions)
Rates	$	502,303	$	94,680,563	$	345,759	$	65,186,563	45.3	%
Credit		15,295		2,893,232		12,871		2,433,824	18.8	%
Equities		7,385		1,397,429		7,543		1,419,622	(2.1)	%
Money Markets		213,920		40,495,243		168,618		31,773,689	26.9	%
Total	$	738,903	$	139,466,467	$	534,791	$	100,813,698	38.2	%

We believe the increases in average daily volumes in nine months ended September 30, 2019 for most asset classes can be attributed to various factors, including further electronification of trading activities across our asset classes, increase in market share, new products, new clients and increased volatility. Trading activity in both long and short-tenor interest rate swaps and swaptions, mortgages and repurchase agreements were the leading drivers of our overall volume growth year-over-year. Rates ADV increased due mainly to higher trading activity in long and short-tenor interest rate swaps and swaptions, mortgages and U.S. treasuries. Credit ADV increased due mainly to higher trading activity in credit derivatives, U.S. high-grade and high-yield credit as well as Chinese bonds. Equities ADV decreased due mainly to lower trading activity in U.S. ETFs. Money Markets ADV increased due to the continued growth of bilateral electronic trading in repurchase agreements.

The average variable fees per million dollars of volume traded on our trading platforms by asset class for the nine months ended September 30, 2019 and 2018 are summarized below. There are four potential drivers of quarterly fluctuations in our average variable fees per million: (1) volume discounts, (2) the mix of cash and derivatives products traded, (3) the mix of protocols underpinning cash and derivatives products and (4) pricing. Average variable fees per million should be reviewed in conjunction with our trading volumes and gross revenue by asset class. Since variable fees are sometimes subject to fee plans with tiered pricing based on product mix and volume, average variable fees per million for a specific asset class may not correlate with volumes or revenue growth. For example, average variable fees per million dollars of volume for our Rates asset class decreased 9.3% for the nine months ended September 30, 2019 while gross revenue for our Rates asset class increased 16.0% over the same period.

Rates average variable fees per million was impacted by growth in short tenor swap volumes, a product which has a lower variable fee capture as compared to other rates products. Credit average variable fees per million was impacted by growth in credit derivatives volumes, products which have a lower variable fee capture as compared to cash credit products, and a decline in municipals volumes. Equities average variable fees per million was impacted by a mix shift in volumes towards Institutional ETFs and away from Wholesale products. Money Markets average variable fees per million was impacted by a mix shift in volumes towards repurchase agreements and away from other lower variable fee capture Money Markets products.

U.S. Revenues from U.S. clients increased by $44.4 million or 13.7% to $368.7 million for the nine months ended September 30, 2019 from $324.3 million for the nine months ended September 30, 2018 primarily due to higher trading volumes from our U.S. credit products, U.S. treasuries, mortgages products,  U.S. dollar-denominated swaps, and U.S. ETFs.

International. Revenues from International clients increased by $28.1 million or 15.5% to $209.6 million for the nine months ended September 30, 2019 from $181.5 million for the nine months ended September 30, 2018 primarily due to higher trading volumes for European interest rate swaps, European equities, Chinese bonds and European repurchase agreements. Fluctuations in foreign currency rates decreased our International gross revenue by $8.3 million.

Operating Expenses

Our expenses for the nine months ended September 30, 2019 and 2018 were as follows:

	September 30,		September 30,

Professional fees		20,981		20,360
Occupancy		10,900		10,732
Total Expenses	$	442,768	$	338,607

Employee Compensation and Benefits. Employee compensation and benefits expense increased by $43.9 million or 21.0% to $252.9 million for the nine months ended September 30, 2019 from $209.0 million for the nine months ended September 30, 2018. The increase was primarily due to $22.4 million of non-cash stock-based compensation expense related to the Special Option Award, which, as a result of the completion of the IPO, we began to expense during the second quarter of 2019 (with $18.9 million recognized as compensation expense related to these options immediately

57

upon the completion of the IPO), and post-IPO options awarded in the third quarter of 2019, an $11.7 million increase in salaries and benefits due to an increase in employee headcount and an increase in commission related expenses of $7.0 million due to higher Wholesale revenues.

Depreciation and Amortization. Depreciation and amortization expense for the nine months ended September 30, 2019 was $102.9 million. Depreciation and amortization expense for the nine months ended September 30, 2018 was $48.8 million. As a result of the Refinitiv Transaction and the application of pushdown accounting, we adjusted our assets and liabilities to their estimated fair values as of October 1, 2018, which resulted in an increase in depreciation of tangible assets and amortization of our intangible assets. The impact of such adjustments increased depreciation and amortization expense during the nine months ended September 30, 2019 by $52.5 million.

Technology and Communications. Technology and communications expense increased by $2.5 million or 9.4% to $29.1 million for the nine months ended September 30, 2019 from $26.6 million for the nine months ended September 30, 2018. The increase was primarily due to increased clearance fees as a result of higher trading volumes.

General and Administrative. General and administrative expense increased by $2.9 million or 12.6% to $26.0 million for the nine months ended September 30, 2019 from $23.1 million for the nine months ended September 30, 2018. The increase was primarily a result of an increase in foreign exchange losses of $1.9 million and an increase in insurance costs of $0.9 million associated with being a public company.

Professional Fees. Professional fees increased by $0.6million or 3.1% to $21.0 million for the nine months ended September 30, 2019 from $20.4 million for the nine months ended September 30, 2018. The increase was primarily due to tax advisory and audit fees, including fees incurred in connection with the IPO, partially offset by decreased legal and consulting fees.

Occupancy. Occupancy expense for the nine months ended September 30, 2019 was $10.9 million. Occupancy expense for the nine months ended September 30, 2018 was $10.7 million. As a result of the Refinitiv Transaction and the application of pushdown accounting, at October 1, 2018, we established a leasehold interest liability, which resulted in a $0.3 million decrease in occupancy expense during the nine months ended September 30, 2019.

Net Interest Income (Expense)

Net interest income (expense) for the nine months ended September 30, 2019 and 2018 was $1.7 million. Net interest income for the nine months ended September 30, 2019 was impacted by credit facility fees related to the Revolving Credit Facility, which we entered into during the second quarter of 2019.

Income Taxes

Provision for income taxes for the nine months ended September 30, 2019 was $21.4 million. Provision for income taxes for the nine months ended September 30, 2018 was $11.9 million. The provision for income taxes for the nine months ended September 30, 2019 was impacted by the Reorganization Transactions and the IPO, which occurred in April 2019 and resulted in Tradeweb Markets Inc. becoming subject to U.S. federal, state and local income taxes with respect to its taxable income, including its allocable share of any taxable income of TWM LLC, and being taxed at prevailing corporate tax rates. Prior to the Reorganization Transactions, income taxes consisted only of business taxes incurred by TWM LLC and certain subsidiaries for business conducted in certain state, local and foreign jurisdictions as well as federal, state and local taxes for certain subsidiaries that are taxed as corporations for U.S. tax purposes.

Liquidity and Capital Resources

Overview

Liquidity describes the ability of a company to generate sufficient cash flows to meet the cash requirements of its business operations, including working capital needs to meet operating expenses, debt service, acquisitions, other

58

commitments and contractual obligations. We consider liquidity in terms of cash flows from operations and availability under the Revolving Credit Facility and their sufficiency to fund our operating and investing activities.

Historically, we have generated significant cash flows from operations and have funded our business operations through cash on hand and cash flows from operations.

Our primary cash needs are for day to day operations, working capital requirements, capital expenditures, primarily for software and equipment, and our expected dividend payments. In addition, we are obligated to make payments under the Tax Receivable Agreement. Although the actual timing and amount of any payments that may be made under the Tax Receivable Agreement will vary, we expect that the payments that we will be required to make under the Tax Receivable Agreement will be significant. Any payments made by us under the Tax Receivable Agreement will generally reduce the amount of overall cash flows that might have otherwise been available to us or to TWM LLC. These payments will offset some of the tax benefits that we expect to realize as a result of the ownership structure of TWM LLC. To the extent that we are unable to make payments under the Tax Receivable Agreement for any reason, the unpaid amounts generally will be deferred and will accrue interest until paid by us.

We expect to fund our liquidity requirements through cash and cash equivalents and cash flows from operations. While historically we have generated significant and adequate cash flows from operations, in the event of an unexpected event in the future or otherwise, we may fund our liquidity requirements through borrowings under the Revolving Credit Facility.

We believe that our projected cash position, cash flows from operations and, if necessary, borrowings under the Revolving Credit Facility, will be sufficient to fund our liquidity requirements for at least the next 12 months. However, our future liquidity requirements could be higher than we currently expect as a result of various factors. For example, any future investments, acquisitions, joint ventures or other similar transactions may require additional capital. In addition, our ability to continue to meet our future liquidity requirements will depend on, among other things, our ability to achieve anticipated levels of revenues and cash flows from operations and our ability to manage costs and working capital successfully, all of which are subject to general economic, financial, competitive and other factors beyond our control. In the event we require any additional capital, it will take the form of equity or debt financing, or both, and there can be no assurance that we will be able to raise any such financing on terms acceptable to us or at all.

As of September 30, 2019 and December 31, 2018, we had cash and cash equivalents of approximately $389.9 million and $410.1 million, respectively. All cash and cash equivalents were held in accounts with banks such that the funds are immediately available or in fixed term deposits with a maximum maturity of three months.

Factors Influencing Our Liquidity and Capital Resources

Dividend Policy

Subject to legally available funds, we intend to pay quarterly cash dividends on our Class A common stock and Class B common stock equal to $0.08 per share. As discussed below, our ability to pay these quarterly cash dividends on our Class A common stock and Class B common stock will depend on distributions to us from TWM LLC. Dividends declared and paid to Class A and B common stockholders during the nine months ended September 30, 2019 amounted to $22.9 million.

The declaration, amount and payment of any dividends will be at the sole discretion of our board of directors and will depend on our and our subsidiaries’ results of operations, capital requirements, financial condition, business prospects, contractual restrictions, restrictions imposed by applicable laws and other factors that our board of directors deem relevant. Because we are a holding company and all of our business is conducted through our subsidiaries, we expect to pay dividends, if any, only from funds we receive from our subsidiaries. Accordingly, our ability to pay dividends to our stockholders is dependent on the earnings and distributions of funds from our subsidiaries. As the sole manager of TWM LLC, we intend to cause, and will rely on, TWM LLC to make distributions in respect of LLC Interests to fund our dividends. If TWM LLC is unable to cause these subsidiaries to make distributions, it may have inadequate funds to distribute to us and we may be unable to fund our dividends. In addition, when TWM LLC makes

59

distributions to us, the other holders of LLC Interests will be entitled to receive proportionate distributions based on their economic interests in TWM LLC at the time of such distributions.

Our board of directors will periodically review the cash generated from our business and the capital expenditures required to finance our growth plans and determine whether to modify the amount of regular dividends and/or declare any periodic special dividends. We currently intend to increase the amount of our expected quarterly dividends in line with free cash flow growth, if any, after giving effect to required tax distributions to be paid by TWM LLC. However, any future determination to change the amount of dividends and/or declare special dividends will be at the discretion of our board of directors and will be dependent upon then-existing conditions and other factors that our board of directors considers relevant.

Cash Distributions

In March and April 2019, TWM LLC made pre-IPO cash distributions to the Original LLC Owners in aggregate amounts of $20.0 million and $100.0 million, respectively.

In May and September 2019, TWM LLC made quarterly cash distributions to its equityholders, including Tradeweb Markets Inc., in aggregate amounts of $33.4 million and $33.0 million, respectively.

On November 5, 2019, Tradeweb Markets Inc., as the sole manager, approved a cash distribution by TWM LLC to its equityholders, including Tradeweb Markets Inc., in an aggregate amount of $45.8 million payable on December 13, 2019.

Cash Dividends

In June and September 2019, Tradeweb Markets Inc. paid quarterly cash dividends to the holders of Class A common stock and Class B common stock in aggregate amounts of $11.4 million for each quarter.

On November 6, 2019, our board of directors declared a cash dividend of $0.08 per share of Class A common stock and Class B common stock for the fourth quarter of 2019. This dividend will be payable on December 16, 2019 to stockholders of record as of December 2, 2019.

Indebtedness

As of September 30, 2019 and December 31, 2018, we had no outstanding indebtedness.

Historically, the Company has only issued debt in connection with significant investment transactions and all debt issued by the Company has been issued to subsidiaries of Thomson Reuters.

On April 8, 2019, TWM LLC entered into the Revolving Credit Facility with a syndicate of banks. The Revolving Credit Facility provides borrowing capacity to be used to fund our ongoing working capital needs, letters of credit and for general corporate purposes, including potential future acquisitions and expansions.

TWM LLC is the borrower under the Revolving Credit Facility. The Revolving Credit Facility permits borrowings of up to $500.0 million by TWM LLC. Subject to the satisfaction of certain conditions, we will be able to increase the Revolving Credit Facility by $250.0 million with the consent of lenders participating in the increase. The Revolving Credit Facility provides for the issuance of up to $5.0 million of letters of credit as well as borrowings on same-day notice, referred to as swingline loans, in an amount of up to $30.0 million. The Revolving Credit Facility will mature on April 8, 2024.

As of September 30, 2019, there were no amounts outstanding under the Revolving Credit Facility and we had availability of $500.0 million.

60

Under the terms of the credit agreement that governs the Revolving Credit Facility, borrowings under the Revolving Credit Facility bear interest at a rate equal to, at our option, either (a) a base rate equal to the greatest of (i) the administrative agent’s prime rate, (ii) the federal funds effective rate plus ½ of 1.0% and (iii) one month LIBOR plus 1.0%, in each case plus 0.75%, or (b) LIBOR plus 1.75%, subject to a 0.00% floor. The credit agreement also requires that we pay a commitment fee of 0.25% for available but unborrowed amounts.  We are also required to pay customary letter of credit fees and agency fees.

We have the option to voluntarily repay outstanding loans at any time without premium or penalty other than customary “breakage” costs with respect to LIBOR loans.

There will be no scheduled amortization under the Revolving Credit Facility. The principal amount outstanding will be due and payable in full at maturity.

Obligations under the Revolving Credit Facility are guaranteed by our existing and future direct and indirect material wholly-owned domestic subsidiaries, subject to certain exceptions. The Revolving Credit Facility is secured by a first-priority security interest in substantially all of the assets of TWM LLC and the guarantors under the facility, subject to certain exceptions.

The credit agreement that governs the Revolving Credit Facility contains a number of covenants that, among other things and subject to certain exceptions, restrict the ability of TWM LLC and the ability of its restricted subsidiaries to:

· incur additional indebtedness and guarantee indebtedness;

· create or incur liens;

· pay dividends and distributions or repurchase capital stock;

· make investments, loans and advances; and

· enter into certain transactions with affiliates.

The Revolving Credit Facility contains a financial covenant requiring compliance with a (i) maximum total net leverage ratio tested on the last day of each fiscal quarter not to exceed 3.5 to 1.0 (increasing to 4.0 to 1.0 for the four-quarter period following a material acquisition and the fiscal quarter in which such material acquisition is consummated) and (ii) minimum cash interest coverage ratio tested on the last day of each fiscal quarter not less than 3.0 to 1.0.

The credit agreement that governs the Revolving Credit Facility also contains certain affirmative covenants and events of default customary for facilities of this type, including relating to a change of control. See Item 5, “Other Information” elsewhere in this Quarterly Report on Form 10 Q. If an event of default occurs, the lenders under the Revolving Credit Facility will be entitled to take various actions, including the acceleration of amounts due under the Revolving Credit Facility and all actions permitted to be taken by secured creditors under applicable law. As of September 30, 2019, we were in compliance with all the covenants set forth in the Revolving Credit Facility.

Capital Requirements

Certain of our U.S. subsidiaries are registered as broker-dealers, SEFs or introducing brokers and are subject to the applicable rules and regulations of the SEC and CFTC. These rules contain minimum net capital or other financial resource requirements, as defined in the applicable regulations. These rules may also require a significant part of the registrants’ assets be kept in relatively liquid form. Certain of our foreign subsidiaries are regulated by the Financial Conduct Authority in the U.K., the Nederlandsche Bank in the Netherlands, the Japanese Financial Services Agency, the Japanese Securities Dealers Association and other foreign regulators, and must maintain financial resources, as defined in the applicable regulations, in excess of the applicable financial resources requirement. As of September 30, 2019 and December 31, 2018, each of our regulated subsidiaries had maintained sufficient net capital or financial resources to at least satisfy their minimum requirements which in aggregate were $50.4 million and $41.7 million, respectively. We

61

maintain capital balances in these subsidiaries in excess of our minimum requirements in order to satisfy working capital needs and to ensure that we have enough cash on hand to satisfy margin requirements and credit risk, including the excess capital expectations of our clients.

Fails to Deliver/Fails to Receive

At times, transactions executed on our wholesale platform fail to settle due to the inability of a transaction party to deliver or receive the transacted security. Until the failed transaction settles, we will recognize a receivable from (and a matching payable to) brokers and dealers and clearing organizations for the proceeds from the unsettled transaction. The impact on our liquidity and capital resources is minimal as receivables and payables for failed transactions are usually recognized simultaneously and predominantly offset.  See Note 4 – Receivable to and Payable from Brokers and Dealers and Clearing Organizations to our unaudited consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Working Capital

Working capital is defined as current assets minus current liabilities. Current assets consist of cash and cash equivalents, restricted cash, receivable from brokers and dealers and clearing organizations, deposits with clearing organizations, accounts receivable and receivable from affiliates. Current liabilities consist of securities sold under agreements to repurchase, payable to brokers and dealers and clearing organizations, accrued compensation, deferred revenue, accounts payable, accrued expenses and other liabilities, employee equity compensation payable, lease liability, payable to affiliates and tax receivable agreement liability. Changes in working capital, which impact our cash flows provided by operating activities, can vary depending on factors such as delays in the collection of receivables, changes in our operating performance, changes in trading patterns, changes in client billing terms and other changes in the demand for our platforms and solutions. Our working capital as of September 30, 2019 and December 31, 2018 was as follows:

	September 30,		December 31,
	2019		2018

Current assets

Current assets increased to $1.3 billion as of September 30, 2019 from $687.8 million as of December 31, 2018 due to an increase in receivable from brokers and dealers and clearing organizations resulting from a higher number of fails to deliver as a result of increased unsettled wholesale platform transactions. On October 1, 2019, approximately $698.8 million of the receivable from brokers and dealers and clearing organizations balance at September 30, 2019 was settled.

62

Current liabilities

Current liabilities increased to $922.4 million as of September 30, 2019 from $391.0 million as of December 31, 2018 due to an increase in payable to brokers and dealers and clearing organizations resulting from a higher number of fails to receive as a result of increased unsettled wholesale platform transactions. On October 1, 2019, approximately $664.3 million of the payable from brokers and dealers and clearing organizations balance at September 30, 2019 was settled. In addition, there was a decrease in accrued compensation and employee equity compensation payments as a result of annual payments.

See Note 4 – Receivable to and Payable from Brokers and Dealers and Clearing Organizations to our unaudited consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q, for more information regarding the fails to deliver/receive and the subsequent settlement.

Cash Flows

Our cash flows for the nine months ended September 30, 2019 and 2018 were as follows:

	Successor		Predecessor
	Nine		Nine
	Months		Months
	Ended		Ended
	September 30,		September 30,
	2019		2018

Effect of exchange rate changes on cash and cash equivalents		(2,016)		(2,043)
Net decrease in cash and cash equivalents	$	(20,174)	$	(2,415)

Operating Activities

Operating activities consist primarily of net income adjusted for noncash items that include depreciation and amortization, stock-based compensation expense and contingent consideration. Cash flows from operating activities can fluctuate significantly from period-to-period as working capital needs and the timing of payments for accrued compensation (primarily in the first quarter) and other items impact reported cash flows.

Net cash provided by operating activities for the nine months ended September 30, 2019 was $190.5 million, an increase of 15.6% over 2018, and primarily driven by an increase in gross revenue.

Investing Activities

Investing activities consist of software development costs, investments in technology hardware, purchases of equipment and other tangible assets, business acquisitions and investments.

Net cash used in investing activities was $29.8 million for the nine months ended September 30, 2019, which consisted of $21.2 million of capitalized software development costs and $8.6 million of purchases of furniture, equipment, purchased software and leasehold improvements. Net cash used in investing activities was $25.8 million for the nine months ended September 30, 2018, which consisted of $19.5 million of capitalized software development costs and $6.3 million of purchases of furniture, equipment, purchased software and leasehold improvements.

63

Financing Activities

Financing activities primarily consist of cash dividends to our Class A and Class B common stockholders and cash distributions from TWM LLC to the Original LLC Owners during the pre-IPO period.

Net cash used in financing activities for the nine months ended September 30, 2019 was $178.9 million, which consisted of purchases of LLC Interests of $1,161.3 million from certain of the Bank Stockholders using the net proceeds from the IPO, cash dividends to our Class A and Class B common stockholders of $22.9 million and capital distributions to the Original LLC Owners of $143.7 million, including a one-time distribution of $100.0 million paid in connection with the IPO. Net cash used in financing activities for the nine months ended September 30, 2018 was $139.4 million, which consisted of capital distributions to the Original LLC Owners.

Non-GAAP Financial Measures

Free Cash Flow

In addition to cash flow from operating activities presented in accordance with GAAP, we use Free Cash Flow to measure liquidity. Free Cash Flow is defined as cash flow from operating activities less expenditures for capitalized software development costs and furniture, equipment and leasehold improvements.

We present Free Cash Flow because we believe it is a useful indicator of liquidity that provides information to management and investors about the amount of cash generated from our core operations after expenditures for capitalized software development costs and furniture, equipment and leasehold improvements.

Free Cash Flow has limitations as an analytical tool, and you should not consider Free Cash Flow in isolation or as an alternative to cash flow from operating activities or any other liquidity measure determined in accordance with GAAP. You are encouraged to evaluate each adjustment. In addition, in evaluating Free Cash Flow, you should be aware that in the future, we may incur expenditures similar to the adjustments in the presentation of Free Cash Flow. In addition, Free Cash Flow may not be comparable to similarly titled measures used by other companies in our industry or across different industries.

The table set forth below presents a reconciliation of our cash flow from operating activities to Free Cash Flow for the nine months ended September 30, 2019 and 2018:

	Successor		Predecessor
	Nine		Nine
	Months		Months
	Ended		Ended
	September 30,		September 30,

Less: Purchases of furniture, equipment and leasehold improvements		(8,567)		(6,327)
Free Cash Flow	$	160,698	$	138,978

Adjusted EBITDA, Adjusted EBITDA margin, Adjusted EBIT, Adjusted EBIT margin, Adjusted Net Income and Adjusted Diluted EPS

In addition to net income and net income attributable to Tradeweb Markets Inc., each presented in accordance with GAAP, we present Adjusted EBITDA, Adjusted EBITDA margin, Adjusted EBIT and Adjusted EBIT margin as measures of our operating performance and Adjusted Net Income and Adjusted Net Income per diluted share (“Adjusted Diluted EPS”) as measures of our profitability.

64

Adjusted EBITDA, Adjusted EBITDA margin, Adjusted EBIT and Adjusted EBIT margin

Adjusted EBITDA is defined as net income before contingent consideration, net interest income, provision for income taxes and depreciation and amortization, adjusted for the impact of certain other items, including certain stock-based compensation expense and gains and losses from outstanding foreign exchange forward contracts and the revaluation of foreign denominated cash. Adjusted EBIT is defined as net income before contingent consideration, net interest income and provision for income taxes, adjusted for the impact of certain other items, including certain stock-based compensation expense, acquisition and Refinitiv Transaction-related depreciation and amortization and gains and losses from outstanding foreign exchange forward contracts and the revaluation of foreign denominated cash. Adjusted EBITDA margin and Adjusted EBIT margin are defined as Adjusted EBITDA and Adjusted EBIT, respectively, divided by gross revenue for the applicable period. We present Adjusted EBITDA, Adjusted EBITDA margin, Adjusted EBIT and Adjusted EBIT margin because we believe they assist investors and analysts in comparing our operating performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance.  For example, we exclude contingent consideration because it is equity settled and its balance is based on our value at a certain time and may not reflect our actual operating performance. In addition, we also exclude non-cash stock-based compensation expense associated with the Special Option Award discussed below under “— Critical Accounting Policies and Estimates — Stock-Based Compensation,” as well as non-cash stock-based compensation expense associated with options awarded to management and other employees following the IPO during 2019. We believe it is useful to exclude this stock-based compensation expense because the amount of expense associated with the Special Option Award and the post-IPO option awards in 2019 may not directly correlate to the underlying performance of our business and will vary across periods. We do not expect to exclude any non-cash stock-based compensation expense associated with options that may be awarded to management and other employees during 2020. With respect to Adjusted EBIT and Adjusted EBIT margin, we believe it is useful to exclude the depreciation and amortization of acquisition related tangible and intangible assets resulting from certain acquisitions, the Refinitiv Transaction and the application of pushdown accounting in order to facilitate a period-over-period comparison of our financial performance.

Management and our board of directors use Adjusted EBITDA, Adjusted EBITDA margin, Adjusted EBIT and Adjusted EBIT margin to assess our financial performance and believe it is helpful in highlighting trends in our core operating performance, while other measures can differ significantly depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which we operate and capital investments. Further, our executive incentive compensation is based in part on components of Adjusted EBITDA and Adjusted EBITDA margin.

Adjusted Net Income and Adjusted Diluted EPS

We present Adjusted Net Income and Adjusted Diluted EPS for Tradeweb Markets Inc. for post-IPO periods and Tradeweb Markets LLC for pre-IPO periods.  As discussed below, because Adjusted Net Income and Adjusted Diluted EPS give effect to certain tax related adjustments to reflect an assumed effective tax rate for all periods presented and, for post-IPO periods, assumes all LLC Interests held by non-controlling interests are exchanged for shares of Class A or Class B common stock, we believe that Adjusted Net Income and Adjusted Diluted EPS for Tradeweb Markets Inc. and Tradeweb Markets LLC are comparable.

Adjusted Net Income is defined as net income attributable to Tradeweb Markets Inc. assuming the full exchange of all outstanding LLC Interests held by non-controlling interests for shares of Class A common stock or Class B common stock of Tradeweb Markets Inc., for post-IPO periods, and net income, for pre-IPO periods, in each case adjusted for contingent consideration, certain stock-based compensation expense, acquisition and Refinitiv Transaction related depreciation and amortization and gains and losses from outstanding foreign exchange forward contracts and the revaluation of foreign denominated cash. Adjusted Net Income also gives effect to certain tax related adjustments to reflect an assumed effective tax rate and, for pre-IPO periods, assumes TWM LLC was subject to a corporate tax rate for the periods presented. Adjusted Diluted EPS is defined as Adjusted Net Income divided by the diluted weighted average number of shares of Class A common stock and Class B common stock outstanding for the applicable period, assuming the full exchange of all outstanding LLC Interests held by non-controlling interests for shares of Class A common stock or Class B common stock, for post-IPO periods, and the diluted weighted average number of shares of TWM LLC outstanding for the applicable period, for pre-IPO periods. The diluted weighted average number of shares outstanding

65

for the pre-IPO periods and post-IPO periods give effect to potentially dilutive securities using the treasury stock method.

We use Adjusted Net Income and Adjusted Diluted EPS as supplemental metrics to evaluate our business performance in a way that also considers our ability to generate profit without the impact of certain items. We exclude contingent consideration, stock-based compensation expense associated with the Special Option Award and the post-IPO option awards in 2019 and acquisition and Refinitiv Transaction-related depreciation and amortization for the reasons described above. Each of the normal recurring adjustments and other adjustments described in the definition of Adjusted Net Income helps to provide management with a measure of our operating performance over time by removing items that are not related to day-to-day operations or are non-cash expenses. In addition to excluding items that are non-recurring or may not be indicative of our ongoing operating performance, by assuming the full exchange of all outstanding LLC Interests held by non-controlling interests, we believe that Adjusted Net Income and Adjusted Diluted EPS for Tradeweb Markets Inc. facilitate comparisons with other companies that have different organizational and tax structures, as well as comparisons period over period, because it eliminates the effect of any changes in net income attributable to Tradeweb Markets Inc. driven by increases in our ownership of TWM LLC, which are unrelated to our operating performance.

Adjusted EBITDA, Adjusted EBITDA margin, Adjusted EBIT, Adjusted EBIT margin, Adjusted Net Income and Adjusted Diluted EPS have limitations as analytical tools, and you should not consider these non-GAAP financial measures in isolation or as alternatives to net income attributable to Tradeweb Markets Inc., net income, operating income, gross margin, earnings per share or any other financial measure derived in accordance with GAAP. You are encouraged to evaluate each adjustment and, as applicable, the reasons we consider it appropriate for supplemental analysis. In addition, in evaluating Adjusted EBITDA, Adjusted EBITDA margin, Adjusted EBIT, Adjusted EBIT margin, Adjusted Net Income and Adjusted Diluted EPS you should be aware that in the future, we may incur expenses similar to the adjustments in the presentation of these non-GAAP financial measures. Our presentation of Adjusted EBITDA, Adjusted EBITDA margin, Adjusted EBIT, Adjusted EBIT margin, Adjusted Net Income and Adjusted Diluted EPS should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. In addition, Adjusted EBITDA, Adjusted EBITDA margin, Adjusted EBIT, Adjusted EBIT margin, Adjusted Net Income and Adjusted Diluted EPS may not be comparable to similarly titled measures used by other companies in our industry or across different industries.

(1) Represents non-cash stock-based compensation expense associated with the Special Option Award and post-IPO options awarded in the third quarter of 2019.

(2) Represents foreign exchange gain or loss from the revaluation of cash denominated in a different currency than the entity’s functional currency.

(3) Represents acquisition-related intangibles amortization and increased tangible asset and capitalized software depreciation and amortization resulting from the Refinitiv Transaction and the application of pushdown accounting (where all assets were marked to fair value as of the closing date of the Refinitiv Transaction).

(4) For the three and nine months ended September 30, 2019, Adjusted EBITDA margin increased compared to the prior year period by 620 and 276 basis points, respectively, or 672 and 326 basis points on a constant currency basis. For the three and nine months ended September 30, 2019 and 2018, Adjusted EBIT margin increased compared to the prior year period by 701 basis points and 321 basis points, respectively, or 770 basis points and 386 basis points on a constant currency basis. Changes in Adjusted EBITDA margin and Adjusted EBIT margin on a constant currency basis, which are non-GAAP financial measures, are defined as the changes in Adjusted EBITDA margin and Adjusted EBIT margin excluding the effects of foreign currency fluctuations. Adjusted EBITDA margin and Adjusted EBIT margin excluding the effects of foreign currency fluctuations are calculated by translating the current period and prior period’s results using the average exchange rates for 2018. We use changes in Adjusted EBITDA margin and Adjusted EBIT margin on a constant currency basis as supplemental metrics to evaluate our underlying margin performance between periods by removing the impact of foreign currency fluctuations. We believe that providing changes in Adjusted EBITDA margin and Adjusted EBIT margin on a constant currency basis provide useful comparisons of our Adjusted EBITDA margin and Adjusted EBIT margin and trends between periods.

Off-Balance Sheet Arrangements

As of September 30, 2019, we did not have any off-balance sheet arrangements.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with U.S. GAAP which requires us to make estimates and assumptions about future events that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. Management evaluates its accounting policies, estimates and judgments on an on-going basis.

Management evaluated the development and selection of its critical accounting policies and estimates and believes that the following policies are most critical to the portrayal of our financial condition and results of operations, and that require our most difficult, subjective or complex judgments in estimating the effect of inherent uncertainties. With respect to critical accounting policies, even a relatively minor variance between actual and expected experience can potentially have a materially favorable or unfavorable impact on subsequent results of operations. More information on all of our significant accounting policies can be found in Note 2 – Significant Accounting Policies to our unaudited consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in our consolidated financial statements and accompanying notes. These estimates and assumptions are based on judgment and the best available information at the time. Management bases its estimates on historical experience, observance of trends in particular areas, information available from outside sources and various other assumptions that are believed to be reasonable under the circumstances. Information from these sources form the basis for making judgments about the carrying values of assets and liabilities that may not be readily apparent from other sources. Therefore, actual results could differ materially from those estimates. Such estimates include pushdown accounting, intangible assets, goodwill, software development costs, stock based compensation, contingent consideration payable and current and deferred income taxes.

Pushdown Accounting

The Refinitiv Transaction was accounted for by Refinitiv in accordance with the acquisition method of accounting pursuant to ASC 805 “Business Combinations” and pushdown accounting was applied to Refinitiv to record the fair value of the assets and liabilities of Refinitiv on the date of the Refinitiv Transaction. We, as a consolidating subsidiary of Refinitiv, also accounted for the Refinitiv Transaction using pushdown accounting. Under pushdown accounting, the

69

excess of our fair value above the fair value accounting basis of our net assets and liabilities is recorded as goodwill. The fair value of assets acquired and liabilities assumed was determined based on assumptions that reasonable market participants would use in the principal (or most advantageous) market for the asset or liability.

In determining the fair value of the assets acquired and the liabilities assumed, we considered a report of a third-party valuation expert. Management is responsible for these internal and third-party valuations and appraisals.

Intangible Assets

We amortize our intangible assets over the estimated useful lives and test for impairment whenever events or changes in circumstances suggest that an asset’s or asset group’s carrying value may not be fully recoverable. We test our intangible assets with an indefinite useful life for impairment at least annually. An impairment loss is recognized if the sum of the estimated discounted cash flows relating to the asset or asset group is less than the corresponding carrying value. Intangible assets are amortized over their estimated useful lives of seven to sixteen years.

Goodwill

Goodwill arises out of pushdown accounting and business combinations and is the cost of acquired companies in excess of the fair value of identifiable net assets at acquisition date. We test our goodwill at least annually for impairment and recognize an impairment loss if the estimated fair value of a reporting unit is less than its net book value. The Company is one reporting unit for goodwill impairment testing purposes. The fair value of a reporting unit is calculated based on the fair market value of the Company’s Class A and B common shares. We calculate such loss as the difference between the estimated fair value of goodwill and its carrying value. If future events or results differ adversely from the estimates and assumptions made at acquisition or as part of subsequent impairment tests, we may record increased amortization or impairment charges in the future.

Software Development Costs

We capitalize certain costs associated with the development of internal use software at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed, including among other items, employee compensation and related benefits and third-party consulting costs incurred during the application development stage which directly contribute to such development. Such costs are amortized on a straight-line basis over three years. Costs capitalized as part of the pushdown accounting allocation are amortized over nine years. We review the amounts capitalized for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable, or that their useful lives are shorter than originally expected. Due to rapidly changing technology and the uncertainty of the software development process itself, future results could be affected if management’s current assessment of its software projects differs from actual performance.

Revenue Recognition

We earn fees from Refinitiv relating to the sale of market data to Refinitiv, which redistributes that data. Included in these fees are real-time market data fees which are recognized in the period that the data is provided, generally on a monthly basis, and fees for historical data sets which are recognized when the historical data set is provided to Refinitiv.  We are required to make significant judgements for the Refinitiv market data fees. Significant judgements used in accounting for this contract include:

· The provision of real-time market data feeds and annual historical data sets are distinct performance obligations.

· The performance obligations under this contract are recognized over time from the initial delivery of the data feeds or each historical data set until the end of the contract term.

70

· Determining the transaction price for the performance obligations by using a market assessment analysis. Inputs in this analysis include a consultant study which determined the overall value of our market data and pricing information for historical data sets provided by other companies.

Stock-Based Compensation

The stock-based compensation that our employees receive is accounted for as equity or liability awards. As a stock-based equity award, the Company measures and recognizes the cost of employee services received in exchange for awards of equity instruments based on their estimated fair values measured as of the grant date. These costs are recognized as an expense over the requisite service period, with an offsetting increase to additional paid-in capital.

As a stock-based liability award, the cost of the employee services received in exchange for an award of equity instruments is generally measured based on the grant-date fair value of the award. The fair value of that award is remeasured subsequently at each reporting date through to settlement. Changes in the fair value of the equity instrument are recognized as compensation cost over that period in our consolidated statements of income.

For grants made during the post-IPO period, the fair value of the equity instruments is determined based on the price of the Company’s Class A common stock on the grant date.

Prior to the IPO, we awarded options to management and other employees (collectively, the “Special Option Award”) under the Amended and Restated Tradeweb Markets Inc. Option Plan. In accounting for the options issued under this plan, we measure and recognize compensation expense for all awards based on their estimated fair values measured as of the grant date. Costs related to these options are recognized as an expense in our consolidated statements of income over the requisite service period, with an offsetting increase to additional paid-in capital. We expect the non-cash stock-based compensation expense associated with the Special Option Award to be between approximately $33.5 million and $35.7 million, respectively, which we started to expense beginning in the second quarter of 2019, with a charge of $20.4 million ($18.9 million of which was charged immediately upon the completion of the IPO), and will continue to expense over the following three years. For more information, please see “Executive Compensation—Narrative Disclosure to Summary Compensation Table—Amended and Restated Tradeweb Markets Inc. 2018 Share Option Plan” in the October Prospectus.

We use the Black-Scholes pricing model to value some of our stock-based awards. Determining the appropriate fair value model and calculating the fair value of the stock-based awards requires the input of highly subjective assumptions, including the expected life of the stock-based awards, the number of expected stock-based awards that will be forfeited prior to the completion of the vesting requirements, and the stock price volatility.

Income Taxes

Tradeweb Markets Inc. is subject to U.S. federal, state and local income taxes with respect to its taxable income, including its allocable share of any taxable income of TWM LLC, and is taxed at prevailing corporate tax rates. TWM LLC is a multiple member limited liability company taxed as a partnership and accordingly any taxable income generated by TWM LLC is passed through to and included in the taxable income of its members, including us for the post-IPO period, on a pro rata basis. TWM LLC records taxes for conducting business in certain state, local and foreign jurisdictions and records U.S. federal taxes for subsidiaries that are taxed as corporations for U.S, tax purposes. We currently record deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities and measure the deferred taxes using the enacted tax rates and laws that will be in effect when such temporary differences are expected to reverse. We believe that it is more likely than not that the Company will be able to realize its deferred tax assets in the future; therefore, no valuation allowance is necessary.

We recognize interest and penalties related to unrecognized tax benefits within the provision for income taxes in our consolidated statements of income. Accrued interest and penalties are included within accounts payable, accrued expenses and other liabilities in our consolidated statements of financial condition.

71

We have elected to treat taxes due on future U.S. inclusions in taxable income under the GILTI provision of the Tax Cuts and Jobs Act as a current period expense when incurred.

Tax Receivable Agreement

Tradeweb Markets Inc. entered into a Tax Receivable Agreement with TWM LLC and the Continuing LLC Owners which provides for the payment by Tradeweb Markets Inc. to a Continuing LLC Owner of 50% of the amount of U.S. federal, state and local income or franchise tax savings, if any, that Tradeweb Markets Inc. actually realizes (or in some circumstances is deemed to realize) as a result of (i) increases in the tax basis of TWM LLC’s assets resulting from (a) the purchase of LLC Interests from such Continuing LLC Owner, including with the net proceeds from the IPO and any future offering or (b) redemptions or exchanges by such Continuing LLC Owner of LLC Interests for shares of Class A common stock or Class B common stock or for cash, as applicable, and (ii) certain other tax benefits related to Tradeweb Markets Inc. making payments under the Tax Receivable Agreement.

We recorded an initial liability of $171.4 million related to our projected obligations under the Tax Receivable Agreement with respect to LLC Interests that were purchased by us using the net proceeds from the IPO. The impact of any changes in the projected obligations under the Tax Receivable Agreement as a result of changes in the geographic mix of the our earnings, changes in tax legislation and tax rates or other factors that may impact our tax savings will be reflected in income before taxes in the period in which the change occurs.

Contingent Consideration

In 2014, we issued Class A Shares and unvested Class P‑1(A) Shares to some of the Bank Stockholders as a result of a capital contribution to facilitate our expansion into new credit products. The proceeds from the issuance of the shares were included in members’ capital. In connection with the investment, certain employees also invested in the Company and were issued Class C Shares and unvested Class P‑1(C) Shares. The proceeds from the issuance of these shares were included in members’ capital. The Class A Shares and Class C Shares issued in connection with the investment equally participated in the earnings of the Company together with the other Class A Shares, Class P(A) Shares, Class C Shares and Class P(C) Shares of the Company. Most of the holders of Class A shares had the right to appoint members to the board of managers of the Company. The Class P‑1(A) Shares and Class P‑1(C) Shares did not have any earnings participation rights, nor did any of the Class P‑1(A) Shares have the right to appoint members to the former board of managers, until they vested. The Class P‑1(A) Shares and Class P‑1(C) Shares vested in July 2018 upon the achievement of specific revenue earnout milestones related to the growth of our credit products, as defined by the agreement, from August 2014 through the vesting date of July 2018.

Prior to the July 2018 vesting, we recognized contingent consideration with respect to the potential vesting of Class P‑1(A) Shares and Class P‑1(C) Shares as a contra-revenue adjustment in accordance with ASC 605‑50‑45‑2 because the vesting could be viewed as a sales incentive to participating Bank Stockholders since they are also customers of the Company. The contingent consideration for each reporting period was calculated by estimating the final contingent consideration value using a monte carlo simulation and recognizing that value on a straightline basis over the 48-month period of the agreement, adjusting at each reporting period for any changes in the final value estimate. The revenue milestones provided that shares would vest only if certain credit revenue milestones would be achieved in the twelve months ended July 2016, 2017 and 2018.

As a result of achieving these milestones, the final earnout amount was calculated based on the credit revenues during the twelve months ended July 31, 2018. On July 31, 2018, members’ capital increased by $150.5 million as a result of the vesting of the Class P‑1(A) Shares and employee equity compensation payable increased by $5.7 million as a result of the vesting of the Class P‑1(C) Shares. The value of the vested Class P‑1(C) Shares was included in employee equity compensation payable because the Class P‑1(C) were owned for less than six months by employees who had the ability to exercise a put option of those shares under certain conditions under their control.

Recent Accounting Pronouncements – Recently Adopted

Effective January 1, 2019, we adopted ASC 842, Leases. This standard requires us to recognize a right-of-use asset and a lease liability for all leases with an initial term in excess of twelve months. The asset reflects the present value of unpaid lease payments coupled with initial direct costs, prepaid lease payments and lease incentives. The amount of the lease liability is calculated as the present value of unpaid lease payments. We adopted ASC 842 prospectively and elected to take the package of practical expedients allowing us not to reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for any existing leases.

On January 1, 2019, upon the adoption of ASC 842, we recorded right-to-use assets of $34.8 million, lease liabilities of $39.6 million and eliminated deferred rent of $4.9 million.

See Note 2 – Significant Accounting Policies to our unaudited consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for information regarding recent accounting pronouncements not yet adopted.

Effects of Inflation

While inflation may impact our revenues and operating expenses, we believe the effects of inflation, if any, on our results of operations and financial condition have not been significant. However, there can be no assurance that our results of operations and financial condition will not be materially impacted by inflation in the future.

Jumpstart Our Business Startups Act of 2012

The Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) permits us, as an “emerging growth company,” to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for public companies that are not emerging growth companies. This decision to opt out of the extended transition period under the JOBS Act is irrevocable.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

Foreign Currency and Derivative Risk

We have global operations and substantial portions of our revenues, expenses, assets and liabilities are generated and denominated in non-U.S. dollar currencies.

The following table shows the percentage breakdown of our gross revenue and operating expenses denominated in currencies other than the U.S. dollar for the three and nine months ended September 30, 2019 and 2018:

	Successor						Predecessor
	Three			Nine			Three			Nine
	Months			Months			Months			Months
	Ended			Ended			Ended			Ended
	September 30,			September 30,			September 30,			September 30,
	2019			2019			2018			2018
% of revenue denominated in foreign currencies (1)		32	%		31	%		30	%		29	%
% of operating expenses denominated in foreign currencies (2)		16	%		15	%		19	%		17	%

(1) Gross revenue in foreign currencies is primarily denominated in Euros.

(2) Operating expenses in foreign currencies are primarily denominated in British pounds.

Since our consolidated financial statements are presented in U.S. dollars, we must translate revenues and expenses, as well as assets and liabilities, into U.S. dollars. Accordingly, increases or decreases in the value of the U.S. dollar

73

against the other currencies will affect our net operating revenues, operating income and the value of balance sheet items denominated in foreign currencies. Revenues and expenses denominated in currencies other than the U.S. dollar are translated at the rate of exchange prevailing at the transaction date. Assets and liabilities denominated in foreign currencies are translated at the rate prevailing at the end of the reporting period. Any gain or loss resulting from the translation of assets and liabilities is included as a component of comprehensive income.

The following table shows the change in gross revenue and operating income caused by fluctuations in foreign currency rates during the three and nine months ended September 30, 2019 and 2018:

	Successor				Predecessor
	Three		Nine		Three		Nine
	Months		Months		Months		Months
	Ended		Ended		Ended		Ended
Impact of Foreign Currency Rate Fluctuations	September 30,		September 30,		September 30,		September 30,
(amounts in thousands)	2019		2019		2018		2018
Increase (decrease) in gross revenue	$	(3,600)	$	(8,400)	$	(500)	$	1,600
Increase (decrease) in operating income	$	(1,200)	$	(6,400)	$	(300)	$	3,000

The following table shows the impact a hypothetical 10% increase or decrease in the U.S. dollar against all other currencies would have on actual gross revenue and operating income for the three and nine months ended September 30, 2019 and 2018:

	Successor				Predecessor
	Three		Nine		Three		Nine
	Months		Months		Months		Months
	Ended		Ended		Ended		Ended
Hypothetical 10% Change in Value of U.S. Dollar	September 30,		September 30,		September 30,		September 30,
(amounts in thousands)	2019		2019		2018		2018
Effect of 10% change on gross revenue	+/-	$ 6,500	+/-	$ 18,000	+/-	$ 5,000	+/-	$ 14,900
Effect of 10% change on operating income	+/-	$ 4,200	+/-	$ 11,400	+/-	$ 2,700	+/-	$ 9,000

We have derivative risk relating to our foreign currency forward contracts. We enter into foreign currency forward contracts to mitigate our U.S. dollar and British pound sterling versus Euro exposure, generally with a duration of less than twelve months. We do not use derivative instruments for trading or speculative purposes. As of September 30, 2019 and December 31, 2018, the notional amount of our foreign currency forward contracts was $82.5 million and $1.7 million, respectively.

By using derivative instruments to hedge exposures to foreign currency fluctuations, we are exposed to credit risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes us, which creates credit risk for us. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, we are not exposed to the counterparty’s credit risk in those circumstances. We attempt to minimize counterparty credit risk in derivative instruments by entering into transactions with high-quality counterparties whose credit rating is at least upper-medium investment grade.

Credit Risk

We have credit risk relating to our receivables, which are primarily receivables from financial institutions, including investment managers and brokers and dealers. At September 30, 2019 and December 31, 2018, we established an allowance for doubtful accounts of $1.3 million and $1.2 million, respectively, with regard to these receivables.

In the normal course of our business we, as an agent, execute transactions with, and on behalf of, other brokers and dealers. If these transactions do not settle because of failure to perform by either counterparty, we may be obligated to discharge the obligation of the non-performing party and, as a result, may incur a loss if the market value of the instrument is different than the contractual amount. This credit risk exposure, can be directly impacted by volatile trading markets, as our clients may be unable to satisfy their contractual obligations during volatile trading markets.

74

Our policy is to monitor our market exposure and counterparty risk. Counterparties are evaluated for creditworthiness and risk assessment prior to our initiating contract activities. The counterparties’ creditworthiness is then monitored on an ongoing basis, and credit levels are reviewed to ensure that there is not an inappropriate concentration of credit outstanding to any particular counterparty.

For additional information, see Note 16 – Credit Risk to our unaudited consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management has evaluated, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures, as defined in Rule 13(a)‑15(e) of the Exchange Act, as of the end of the period covered by this Quarterly Report on Form 10‑Q. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10‑Q are effective at a reasonable assurance level in ensuring that information required to be disclosed in our Exchange Act reports is (1) recorded, processed, summarized and reported in a timely manner and (2) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures will prevent or detect all errors and all fraud. While our disclosure controls and procedures are designed to provide reasonable assurance of their effectiveness, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected.

Changes in Internal Control over Financial Reporting

There were no changes to our internal control over financial reporting during the quarter ended September 30, 2019 that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.

Exhibit 10.1

Execution Version

AMENDMENT NO. 1

AMENDMENT NO. 1  (this “Amendment”), dated as of November 7, 2019, among Tradeweb Markets LLC, a Delaware limited liability company (the “Borrower”), and each Lender party hereto (constituting the Required Lenders), relating to the Credit Agreement, dated as of April 8, 2019 (the  “Existing Credit Agreement”), among the Borrower, the Lenders party thereto, and Citibank, N.A., as Administrative Agent, Collateral Agent, Issuing Bank and Swing Line Lender.

RECITALS:

WHEREAS, pursuant to Section 9.02(b) of the Existing Credit Agreement, the Borrower has requested an amendment to the Existing Credit Agreement to effect the changes described in Section 2 of this Amendment; and

WHEREAS, the Borrower and the Lenders party hereto which constitute the Required Lenders (the “Consenting Lenders”) have agreed to make the changes described in Section 2 of this Amendment as of the Amendment No. 1 Effective Date (as defined below), subject to the terms and conditions set forth herein.

NOW THEREFORE, the parties hereto therefore agree as follows:

SECTION 1.  Defined Terms. Unless otherwise specifically defined herein, each term used herein that is defined in the Existing Credit Agreement has the meaning assigned to such term in the Existing Credit Agreement.

SECTION 2.  Amendments to Existing Credit Agreement.  The Existing Credit Agreement is, as of the Amendment No. 1 Effective Date and subject to the satisfaction of the conditions precedent set forth in Section 4 of this Amendment, hereby amended (the Existing Credit Agreement, as so amended, the “Amended Credit Agreement”), as follows:

(a)  The definition of “Investors” in the Existing Credit Agreement shall be replaced in its entirety with the following:

“Investors” means each of (a) the Blackstone Funds and any of their Affiliates (other than any portfolio operating companies), (b) the CPPIB Funds and any of their Affiliates (other than any portfolio operating companies), (c) the GIC Funds and any of its Affiliates (other than any portfolio operating companies), (d) Refinitiv Holdings Ltd. (formerly known as King (Cayman) Holdings Ltd.) and any of its controlled Affiliates and any of their respective Subsidiaries, or (e) London Stock Exchange Group PLC and any of its controlled Affiliates.

SECTION 3.  Representations of the Borrower.  The Borrower hereby represents and warrants to the Consenting Lenders that:

(a)  The execution and delivery of this Amendment are within the Borrower’s corporate or other powers and have been duly authorized by all necessary corporate or other action.

(b)  The Borrower (a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, (b) has all requisite corporate power and authority to carry on its business as now conducted except where the failure to have the same would not reasonably be expected to have Material Adverse Effect and (c) is qualified to do business in, and (where such concept exists) is in good standing (or its equivalent, if any) in, every jurisdiction

where such qualification is required except where the failure to be so qualified or to be (where such concept exists) in good standing (or its equivalent, if any) would not reasonably be expected to have a Material Adverse Effect.

(c)  This Amendment has been duly executed and delivered by the Borrower and constitutes a legal, valid and binding obligation of the Borrower, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

(d)  The execution and delivery of this Amendment by the Borrower (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been, or will be by the time required, obtained or made and are, or will be by the time required, in full force and effect, (b) will not violate the Organizational Documents of the Borrower, (c) will not violate any Requirement of Law applicable to the Borrower, (d) will not violate or result in a default under any indenture, agreement or other instrument binding upon the Borrower or its assets, or give rise to a right thereunder to require any payment to be made by the Borrower or give rise to a right of, or result in, termination, cancellation or acceleration of any obligation thereunder, and (e) will not result in the creation or imposition of any Lien on any asset of the Borrower, except Liens permitted by Section 6.02 of the Existing Credit Agreement, except, in the case of clauses (c) and (d), for any such violations, defaults or rights that, would not reasonably be expected to have a Material Adverse Effect.

(e)  The representations and warranties contained in Article III of the Existing Credit Agreement are true and correct in all material respects (and in all respects if any such representation or warranty is already qualified by materiality) on and as of the Amendment No. 1 Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they were true and correct in all material respects (and in all respects if any such representation or warranty is already qualified by materiality) as of such earlier date.

SECTION 4.  Conditions to the Amendment No. 1 Effective Date.  This Amendment shall become effective as of the first date (the “Amendment No. 1 Effective Date”) when each of the following conditions shall have been satisfied:

(a)       The Administrative Agent shall have received from (i) the Borrower and (ii) each Consenting Lender an executed counterpart hereof.

(b)       Prior to and immediately after giving effect to this Amendment, (i) the conditions set forth in Section 4.02(a) and (b) of the Existing Credit Agreement shall have been satisfied and (ii) the representations and warranties in Section 3 of this Amendment shall be true and correct in all material respects.

SECTION 5.  Acknowledgment of Lenders.  Each Lender party hereto expressly acknowledges that neither the Administrative Agent nor any of its Affiliates nor any of its respective officers, directors, employees, agents or attorneys-in-fact have made any representations or warranties to it and that no act by the Administrative Agent hereafter taken, including any review of the affairs of a Loan Party or any affiliate of a Loan Party, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender.  Each Lender party hereto represents to the Administrative Agent that it has, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates and made its own decision to enter into this Amendment.  Each

2

Lender party hereto also represents that it will, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under the Amended Credit Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates.  Each Lender party hereto hereby (a) confirms that it has received a copy of the Amended Credit Agreement and each other Loan Document and such other documents (including financial statements) and information as it deems appropriate to make its decision to enter into this Amendment, (b) agrees that it shall be bound by the terms of the Amended Credit Agreement as a Lender thereunder and that it will perform in accordance with their terms all of the obligations which by the terms of the Loan Documents are required to be performed by it as a Lender, (c) irrevocably designates and appoints the Administrative Agent as the agent of such Lender under the Amended Credit Agreement and the other Loan Documents, and each such Lender irrevocably authorizes the Administrative Agent, in such capacity, to take such action on its behalf under the provisions of the Amended Credit Agreement and the other Loan Documents and to exercise such powers and perform such duties as are delegated to the Administrative Agent by the terms of the Amended Credit Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto and (d) acknowledges that this Amendment is a “Loan Document” for all purposes of the Amended Credit Agreement and the other Loan Documents.

SECTION 6.  Governing Law.  This Amendment shall be governed by and construed and interpreted in accordance with the laws of the State of New York.

SECTION 7.  Fees & Expenses.  The Borrower hereby reconfirms its respective obligations pursuant to Section 9.03 of the Amended Credit Agreement to pay all reasonable and documented out-of-pocket expenses incurred by the Administrative Agent in connection with this Amendment.  In addition (and without limiting the foregoing), the Borrower agrees to reimburse the Administrative Agent for its reasonable out-of-pocket expenses in connection with this Amendment, including the reasonable fees, charges and disbursements of Cahill Gordon & Reindel LLP, counsel for the Administrative Agent.  The Borrower hereby confirms that the indemnification provisions set forth in Section 9.03 of the Amended Credit Agreement shall apply to this Amendment and the consummation and administration of the transactions contemplated hereby, and such liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs (including settlement costs) expenses and disbursements (including fees, disbursements and charges of counsel) (as more fully set forth therein as applicable) which may arise herefrom or in connection herewith.

SECTION 8.  Amended Credit Agreement Governs.  Except as expressly set forth herein, this Amendment shall not by implication or otherwise limit, impair, constitute a waiver of or otherwise affect the rights and remedies of any Lender or the Administrative Agent under the Amended Credit Agreement or any other Loan Document, and shall not alter, modify, amend or in any way affect any of the terms, conditions, obligations, covenants or agreements contained in the Amended Credit Agreement or any other Loan Document, all of which are ratified and affirmed in all respects and shall continue in full force and effect.  Nothing herein shall be deemed to entitle any Loan Party to a consent to, or a waiver, amendment, modification or other change of, any of the terms, conditions, obligations, covenants or agreements contained in the Amended Credit Agreement or any other Loan Document in similar or different circumstances.

SECTION 9.  Counterparts.  This Amendment may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Delivery of an executed counterpart of a signature page to this Amendment by facsimile or electronic (i.e., “pdf” or “tif”) transmission shall be effective as delivery of a manually executed counterpart of this Amendment.

3

SECTION 10.  Miscellaneous.  This Amendment shall constitute a “Loan Document” for all purposes of the Amended Credit Agreement and the other Loan Documents.

In connection with the Reorganization Transactions, Tradeweb Markets Inc. became the sole manager of TWM LLC and, as a result of this control, and because Tradeweb Markets Inc. has a substantial financial interest in TWM LLC, consolidates the financial results of TWM LLC into its consolidated financial statements. The non-controlling interests balance reported on the consolidated statements of financial condition represents the economic interests of TWM LLC held by the holders of LLC Interests other than Tradeweb Markets Inc. Income or loss is attributed to the non-controlling interests based on the relative ownership percentages of LLC Interests held during the period by Tradeweb Markets Inc. and the other holders of LLC Interests.

The following table summarizes the ownership interest in Tradeweb Markets LLC:

	September 30, 2019

Number of LLC Interests held by Tradeweb Markets Inc.	142,942,945	64.3%
Number of LLC Interests held by non-controlling interests	79,289,005	35.7%
Total LLC Interests outstanding	222,231,950	100%

LLC Interests held by the Continuing LLC Owners are redeemable in accordance with the TWM LLC Agreement at the election of the members for shares of Class A common stock or Class B common stock, on a one-for-one basis or, at the Company's option, a cash payment in accordance with the terms of the TWM LLC Agreement.

Credit Risk

Credit Risk

Credit Risk

16.          Credit Risk

The Company may be exposed to credit risk regarding its receivables, which are primarily receivables from financial institutions, including investment managers and broker/dealers. At September 30, 2019 and December 31, 2018, the Company established an allowance for doubtful accounts of $1.3 million and $1.2 million, respectively, with regard to these receivables.

In the normal course of business the Company, as agent, executes transactions with, and on behalf of, other brokers and dealers. If the agency transactions do not settle because of failure to perform by either counterparty, the Company may be obligated to discharge the obligation of the non-performing party and, as a result, may incur a loss if the market value of the security is different from the contract amount of the transaction.

A substantial number of the Company's transactions are collateralized and executed with, and on behalf of, a limited number of brokers and dealers. The Company's exposure to credit risk associated with the nonperformance of these clients in fulfilling their contractual obligations pursuant to securities transactions can be directly impacted by volatile trading markets which may impair the clients' ability to satisfy their obligations to the Company.

From time to time, the Company enters into agreements to repurchase to facilitate the clearance of securities.  Credit exposure related to these agreements to repurchase, including the risk related to a decline in market value of collateral (pledged or received), is managed by entering into agreements to repurchase with overnight or short-term maturity dates and only entering into repurchase transactions with netting members of the Fixed Income Clearing Corporation (“FICC”). The FICC requires dealer netting members to maintain a minimum of $25 million in equity capital and $10 million in excess net capital. The FICC operates a continuous net settlement system, whereby as trades are submitted and compared the FICC becomes the counterparty. The FICC also marks to market collateral on a daily basis, requiring member firms to pay or receive margin amounts as part of their daily funds settlement.

The Company does not expect nonperformance by counterparties in the above situations. However, the Company's policy is to monitor its market exposure and counterparty risk. In addition, the Company has a policy of reviewing, as considered necessary, the credit standing of each counterparty with which it conducts business.

Significant Accounting Policies (Policies)

Sep. 30, 2019

Significant Accounting Policies

Basis of Accounting

Basis of Accounting

The consolidated financial statements have been presented in conformity with accounting principles generally accepted in the United States of America. All adjustments, which are, in the opinion of management, necessary to a fair statement of the results for the interim periods presented, are normal and recurring in nature. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and the difference may be material to the consolidated financial statements.

Basis of Presentation and Consolidation

Basis of Presentation and Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

As discussed in Note 1—Organization, as a result of the Reorganization Transactions, Tradeweb Markets Inc. consolidates TWM LLC and TWM LLC is considered to be the predecessor to Tradeweb Markets Inc. for financial reporting purposes. As a result, the consolidated financial statements for periods prior to the Reorganization Transactions have been adjusted to combine the previously separate entities for presentation purposes. However, Tradeweb Markets Inc. had no business transactions or activities and no substantial assets or liabilities prior to the Reorganization Transactions. As such, for periods prior to the completion of the Reorganization Transactions, the consolidated financial statements represent the historical financial condition and results of operations of TWM LLC and its subsidiaries. For periods after the completion of the Reorganization Transactions, the consolidated financial statements represent the financial condition and results of operations of the Company and report a non-controlling interest related to the LLC Interests held by the Continuing LLC Owners.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents consists of cash and highly liquid investments (such as short-term money market instruments) with original maturities of less than three months.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts

The Company continually monitors collections and payments from its clients and maintains an allowance for doubtful accounts. The allowance for doubtful accounts is based upon the historical collection experience and specific collection issues that have been identified. Additions, if any, to the allowance for doubtful accounts are charged to bad debt expense, which is included in general and administrative expenses on the consolidated statements of income.

Furniture, Equipment, Purchased Software and Leasehold Improvements

Furniture, Equipment, Purchased Software and Leasehold Improvements

Furniture, equipment, purchased software and leasehold improvements are carried at cost less accumulated depreciation. Depreciation for furniture, equipment and purchased software, including the allocated fair value of assets as a result of pushdown accounting (see Note 3 – Pushdown Accounting), is computed on a straight-line basis over the estimated useful lives of the related assets, ranging from three to seven years. Leasehold improvements are amortized over the lesser of the estimated useful lives of the leasehold improvements or the remaining term of the lease for office space.

Furniture, equipment, purchased software and leasehold improvements are tested for impairment whenever events or changes in circumstances suggest that an asset’s carrying value may not be fully recoverable in accordance with Accounting Standards Codification (“ASC”) 360.

Software Development Costs

Software Development Costs

The Company capitalizes costs associated with the development of internal use software at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed, in accordance with ASC 350. The Company capitalizes employee compensation and related benefits and third party consulting costs incurred during the application development stage which directly contribute to such development. Such costs are amortized on a straight-line basis over three years. Costs capitalized as part of the pushdown accounting allocation (see Note 3 – Pushdown Accounting) are amortized over nine years. The Company reviews the amounts capitalized for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable, or that their useful lives are shorter than originally expected. Non-capitalized software costs and routine maintenance costs are expensed as incurred.

Intangible Assets

Intangible Assets

Intangible assets with a finite life are amortized over the estimated lives, ranging from seven to sixteen years, in accordance with ASC 350. Intangible assets subject to amortization are tested for impairment whenever events or changes in circumstances suggest that an asset's or asset group's carrying value may not be fully recoverable in accordance with ASC 360. Intangible assets with an indefinite useful life are tested for impairment at least annually. An impairment loss is recognized if the sum of the estimated discounted cash flows relating to the asset or asset group is less than the corresponding book value.

Goodwill

Goodwill

Goodwill is the excess of the fair value of the Company above the fair value accounting basis of the net assets and liabilities of the Company under pushdown accounting. Goodwill is also the cost of acquired companies in excess of the fair value of identifiable net assets at the acquisition date. Goodwill is not amortized, but in accordance with ASC 350, goodwill is tested for impairment annually and between annual tests whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. Goodwill is tested at the reporting unit level, which is defined as an operating segment or one level below the operating segment. An impairment loss is recognized if the estimated fair value of a reporting unit is less than its net book value. Such loss is calculated as the difference between the estimated fair value of goodwill and its carrying value.

In 2019, the Company changed the annual date on which goodwill is tested for impairment from July 1st to October 1st to align with the annual impairment testing date of the Company’s Parent. This change did not accelerate, delay, avoid or cause an impairment charge, nor did this change result in adjustments to any previously issued financial statements. Goodwill was last assessed on October 1, 2018 in connection with the Refinitiv Transaction and the application of pushdown accounting.  See Note 3 – Pushdown Accounting.

Deferred IPO and Follow-On Offering Costs

Deferred IPO and Follow-On Offering Costs

In 2018 and the third quarter of 2019, the Company began incurring costs in connection with the filing of a Registration Statement on Form S-1 for an IPO and a Registration Statement on Form S-1 for a follow-on offering, respectively, which are deferred in other assets in accordance with ASC 505-10-25 in the consolidated statements of financial condition. IPO and follow-on offering costs consist of legal, accounting, and other costs directly related to the Company’s efforts to raise capital. As of September 30, 2019, $15.9 million of deferred costs related to the IPO were reclassified from other assets to additional paid-in capital and $0.7 million of deferred costs related to the follow-on offering were included in other assets, in each case on the consolidated statements of financial condition.  See Note 11 – Stockholders’ Equity and Note 21 – Subsequent Events.

Translation of Foreign Currency

Translation of Foreign Currency

Revenues and expenses denominated in foreign currencies are translated at the rate of exchange prevailing at the transaction date. Assets and liabilities denominated in foreign currencies are translated at the rate prevailing at the consolidated statements of financial condition date. Foreign currency re-measurement gains or losses on transactions in nonfunctional currencies are recognized in the consolidated statements of income. Gains or losses on translation in the financial statements of a non-U.S. operation, when the functional currency is other than the U.S. dollar, are included as a component of comprehensive income.

Income Tax

Income Tax

The Corporation is subject to U.S. federal, state and local income taxes with respect to its taxable income, including its allocable share of any taxable income of TWM LLC, and is taxed at prevailing corporate tax rates. TWM LLC is a multiple member limited liability company taxed as a partnership and accordingly any taxable income generated by TWM LLC is passed through to and included in the taxable income of its members, including the Corporation, on a pro rata basis. Income taxes also include unincorporated business taxes on income earned or losses incurred for conducting business in certain state and local jurisdictions, income taxes on income earned or losses incurred in foreign jurisdictions on certain operations and federal and state income taxes on income earned or losses incurred, both current and deferred, on subsidiaries that are taxed as corporations for U.S. tax purposes.

The Company records deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. The Company measures deferred taxes using the enacted tax rates and laws that will be in effect when such temporary differences are expected to reverse. Based on the weight of the positive and negative evidence considered, management believes that it is more likely than not that the Company will be able to realize its deferred tax assets in the future, therefore, no valuation allowance is necessary.

The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process whereby (i) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (ii) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

The Company recognizes interest and penalties related to income taxes within the provision for income taxes in the consolidated statements of income. Accrued interest and penalties are included within accounts payable, accrued expenses and other liabilities in the consolidated statements of financial condition.

The Company has elected to treat taxes due on future U.S. inclusions in taxable income under the global intangible low-taxed income (“GILTI”) provision of the Tax Cuts and Jobs Act as a current period expense when incurred.

Revenue Recognition

Revenue Recognition

The Company earns transaction fees from transactions executed on the Company’s trading platforms through various fee plans. Transaction fees are generated both on a variable and fixed price basis and vary by geographic region, product type and trade size. For variable transaction fees, the Company charges clients fees based on the mix of products traded and the volume of transactions executed. Transaction fee revenue is recorded at a point in time when the trade occurs and is generally billed monthly.

The Company earns subscription fees from granting access to institutional investors to the Company's electronic marketplaces. Subscription fees are recognized into income in the period that access is provided on a monthly basis. Also included in subscription fees are viewer fees earned monthly from institutional investors accessing fixed income market data. The frequency of subscription fee billings varies from monthly to annually, depending on contract terms. Fees received by the Company which are not yet earned are included in deferred revenue on the consolidated statements of financial condition until the revenue recognition criteria has been met.

The Company earns commission revenue from its electronic and voice brokerage services on a riskless principal basis. Riskless principal revenues are derived on matched principal transactions where revenues are earned on the spread between the buy and sell price of the transacted product. Securities transactions and related commission income for brokerage transactions are recognized and recorded on a trade-date basis. Commission revenue is collected by the Company when the trade settles or is billed monthly.

The Company earns fees from Refinitiv, formerly TR in the predecessor periods, relating to the sale of market data to Refinitiv, which redistributes that data. Included in these fees, which are billed quarterly, are real-time market data fees which are recognized in the period that the data is provided, generally on a monthly basis and historical data sets which are recognized when the historical data set is provided to Refinitiv.

On January 1, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers, using the modified retrospective approach. The adoption of ASU 2014-09 did not have a material impact on the measurement or recognition of revenue in any prior reporting periods.  However, subsequent to the adoption, the Company was required to make significant judgements for the Refinitiv market data fees.  Significant judgements used in accounting for this contract include:

· The provision of real-time market data feeds and annual historical data sets are distinct performance obligations.

· The performance obligations under this contract are recognized over time from the initial delivery of the data feeds or each historical data set until the end of the contract term.

· Determining the transaction price for the performance obligations by using a market assessment analysis. Inputs in this analysis include a consultant study which determined the overall value of the Company's market data and pricing information for historical data sets provided by other companies.

Some revenues earned by the Company have fixed fee components, such as monthly minimums or fixed monthly fees, and variable components, such as transaction based fees.

Stock-Based Compensation

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718. ASC 718 focuses primarily on accounting for a transaction in which an entity obtains employee services in exchange for stock-based payments. Under ASC 718, the stock-based payments received by the employees of the Company are accounted for either as equity awards or as liability awards.

As an equity award, the Company measures and recognizes the cost of employee services received in exchange for awards of equity instruments based on their estimated fair values measured as of the grant date. These costs are recognized as an expense over the requisite service period, with an offsetting increase to additional paid-in capital.

As a liability award, the cost of employee services received in exchange for an award of equity instruments is generally measured based on the grant-date fair value of the award. The fair value of that award is remeasured subsequently at each reporting date through the settlement in accordance with ASC 505. Changes in the equity instrument's fair value during the requisite service period are recognized as compensation cost over that period.

For periods following the Reorganization Transactions and the IPO, the fair value of new equity instrument grants is determined based on the price of the Company’s Class A common stock on the grant date.

Under ASC 718, the grant-date fair value of stock-based awards that do not require future service (i.e., vested awards) are expensed immediately. The grant-date fair value of stock-based awards that require future service, and are graded-vesting awards, are amortized over the relevant service period on a straight-line basis, with each tranche separately measured. The grant-date fair value of stock-based awards that require both future service and the achievement of Company performance-based conditions, are amortized over the relevant service period for the performance-based condition. If in a reporting period it is determined that the achievement of a performance target for a performance-based tranche is not probable, then no expense is recognized for that tranche and any expenses already recognized relating to that tranche in prior reporting periods are reversed in the current reporting period.

Prior to the IPO, the Company awarded options to management and other employees (collectively, the “Special Option Award”) under the Amended and Restated Tradeweb Markets Inc. Option Plan (the “Option Plan”). In accounting for the options issued under the Option Plan, compensation expense is measured and recognized for all awards based on their estimated fair values measured as of the grant date. Costs related to these options are recognized as an expense in the consolidated statements of income over the requisite service period, with an offsetting increase to additional paid-in capital. The non-cash stock-based compensation expense associated with the Special Option Award began being expensed in the second quarter of 2019 and will continue to be expensed over the following three years.

Determining the appropriate fair value model and calculating the fair value of the stock-based awards requires the input of highly subjective assumptions, including the expected life of the stock-based awards and the stock price volatility. The Company uses the Black-Scholes pricing model to value some of its stock-based awards.

Earnings Per Share

Earnings Per Share

Basic earnings per share is computed by dividing the net income attributable to the Company's shares by the weighted-average number of the Company's shares outstanding during the period. For purposes of computing diluted earnings per share, the weighted-average number of the Company’s shares reflects the dilutive effect that could occur if securities that qualify as participating securities were converted into or exchanged or exercised for TWM LLC’s shares, in the pre-IPO period, and the Corporation’s Class A or Class B common stock, in the post-IPO period, using the treasury stock method, as applicable.

Shares of Class C and Class D common stock do not have economic rights in Tradeweb Markets Inc. and, therefore, are not participating securities for purposes of the computation of earnings per share.

Fair Value Measurement

Fair Value Measurement

The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). Instruments that the Company owns (long positions) are marked to bid prices, and instruments that the Company has sold, but not yet purchased (short positions) are marked to offer prices. Fair value measurements do not include transaction costs.

The fair value hierarchy under ASC 820 prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under ASC 820 are described below:

Basis of Fair Value Measurement

Level 1:Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: Quoted prices in markets that are not considered to be active or financial instruments for which all significant inputs are observable, either directly or indirectly;

Level 3: Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The ASU provides new guidance for estimating credit losses on certain types of financial instruments by introducing an approach based on expected losses. This ASU is applicable for the Company in the fiscal year beginning January 1, 2020 and requires a modified retrospective method of adoption. The Company is currently in the planning and analysis phase, which involves documenting in-scope financial assets and understanding and leveraging existing credit loss estimation processes.

The Company does not anticipate the adoption of this ASU to have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017‑04, Intangibles – Goodwill and Other. The ASU simplifies the quantitative goodwill impairment test by eliminating the second step of the test. Under this ASU, impairment will be measured by comparing the estimated fair value of the reporting unit with its carrying value. The ASU is applicable for the Company in the fiscal year beginning January 1, 2020. The Company does not anticipate the adoption of this ASU to have a material impact on the Company's consolidated financial statements.

Pushdown Accounting

Pushdown Accounting

3.          Pushdown Accounting

The Refinitiv Transaction was accounted for by Refinitiv in accordance with the acquisition method of accounting pursuant to ASC 805, and pushdown accounting was applied to Refinitiv to record the fair value of the assets and liabilities of Refinitiv on the date of the Refinitiv Transaction. The Company, as a consolidating subsidiary of Refinitiv, also accounted for the Refinitiv Transaction using pushdown accounting. Under pushdown accounting, the excess of the fair value of the Company above the fair value accounting basis of the net assets and liabilities of the Company was recorded as goodwill. At September 30, 2019 and December 31, 2018, goodwill amounted to $2.7 billion.  

The adjusted valuations resulted in an increase in depreciation and amortization expense, due to the increased carrying value of the Company’s assets and the related increase in depreciation of tangible assets and amortization of intangible assets, and a decrease in occupancy expense as a result of the recognition of a leasehold interest liability.

11.          Stockholders’ Equity

Initial Public Offering

As described in Note 1 – Organization, in April 2019, the Corporation completed its IPO of 46,000,000 shares of Class A common stock at a public offering price of $27.00, which included 6,000,000 shares of Class A common stock issued pursuant to the underwriters’ option to purchase additional shares of Class A common stock.  The Corporation received $1.2 billion in net proceeds, after deducting underwriting discounts and commissions but before deducting offering expenses, which were used to purchase LLC Interests from certain of the Bank Stockholders (and the corresponding shares of common stock were cancelled as described below), at a purchase price per interest equal to the public offering price of $27.00, less the underwriting discounts and commissions payable thereon.

Reorganization Transactions

In connection with the IPO, the Reorganization Transactions described below were completed.

Amendment and Restatement of Certificate of Incorporation

On April 3, 2019, the certificate of incorporation of Tradeweb Markets Inc. was amended and restated to, among other things, provide for the authorization of (i) 250,000,000 shares of preferred stock with a par value of $0.00001 per share (ii) 1,000,000,000 shares of Class A common stock with a par value of $0.00001 per share; (iii) 450,000,000 shares of Class B common stock with a par value of $0.00001 per share; (iv) 350,000,000 shares of Class C common stock with a par value of $0.00001 per share; and (v) 300,000,000 shares of Class D common stock with a par value of $0.00001 per share.

Each share of Class A common stock and Class C common stock entitles its holder to one vote on all matters presented to the Corporation’s stockholders generally. Each share of Class B common stock and Class D common stock entitles its holder to ten votes on all matters presented to the Corporation’s stockholders generally. The holders of Class C common stock and Class D common stock have no economic interests in the Corporation (where “economic interests” means the right to receive any dividends or distributions, whether cash or stock, in connection with common stock). These attributes are summarized in the following table:

Class of Common Stock	Par Value		Votes	Economic Rights
Class A common stock	$	0.00001	1	Yes
Class B common stock	$	0.00001	10	Yes
Class C common stock	$	0.00001	1	No
Class D common stock	$	0.00001	10	No

Holders of outstanding shares of Class A common stock, Class B common stock, Class C common stock and Class D common stock will vote together as a single class on all matters presented to the Corporation’s stockholders for their vote or approval, except as otherwise required by applicable law.

Holders of Class B common stock may from time to time exchange all or a portion of their shares of Class B common stock for newly issued shares of Class A common stock on a one-for-one basis (in which case their shares of Class B common stock will be cancelled on a one-for-one basis upon any such issuance). The Continuing LLC Owners that hold shares of Class D common stock may also from time to time exchange all or a portion of their shares of Class D common stock for newly issued shares of Class C common stock on a one-for-one basis (in which case their shares of Class D common stock will be cancelled on a one-for-one basis upon such issuance). In addition, with respect to each Bank Stockholder that holds shares of Class D common stock, immediately prior to the occurrence of any event that would cause the combined voting power held by such Bank Stockholder to exceed 4.9%, the minimum number of shares of Class D common stock of such Bank Stockholder that would need to convert into shares of Class C common stock such that the combined voting power held by such Bank Stockholder would not exceed 4.9% will automatically convert into shares of Class C common stock.

Each share of Class B common stock will automatically convert into one share of Class A common stock and each share of Class D common stock will automatically convert into one share of Class C common stock (i) immediately prior to any sale or other transfer of such share by a holder or its permitted transferees to a non-permitted transferee or (ii) once the Refinitiv Owners and their affiliates together no longer beneficially own a number of shares of common stock and LLC Interests that together entitle them to at least 10% of TWM LLC’s economic interest. Holders of LLC Interests that receive shares of Class C common stock upon any such conversion may continue to elect to have their LLC Interests redeemed for newly issued shares of Class A common stock as described below (in which case their shares of Class C common stock will be cancelled on a one-for-one basis upon such issuance).

Recapitalization of Tradeweb Markets LLC

On April 4, 2019, the TWM LLC Agreement was amended and restated to, among other things, (i) provide for the LLC Interests, (ii) exchange all of the then existing membership interests in TWM LLC for LLC Interests and (iii) appoint the Corporation as the sole manager of TWM LLC.

All of the shares of TWM LLC outstanding prior to the Reorganization Transactions were exchanged for 222,222,197 LLC Interests. TWM LLC’s outstanding shares prior to the Reorganization Transactions consisted of the following classes of shares:

	Shares
Class A	146,333
Class C	447
Class P (A)	6,887
Class P (C)	2
Class P-1(A)	6,094
Class P-1 (C)	232

The TWM LLC Agreement requires that TWM LLC at all times maintain (i) a one-to-one ratio between the number of shares of Class A common stock and Class B common stock issued by the Corporation and the number of LLC Interests owned by the Corporation and (ii) a one-to-one ratio between the number of shares of Class C common stock and Class D common stock issued by the Corporation and the number of LLC Interests owned by the holders of such Class C common stock and Class D common stock.

LLC Interests held by the Continuing LLC Owners are redeemable in accordance with the TWM LLC Agreement, at the election of such holders, for newly issued shares of Class A common stock or Class B common stock, as the case may be, on a one-for-one basis (and such holders’ shares of Class C common stock or Class D common stock, as the case may be, will be cancelled on a one-for-one basis upon any such issuance). In the event of such election by a Continuing LLC Owner, the Corporation may, at its option, effect a direct exchange of Class A common stock or Class B common stock for such LLC Interests of such Continuing LLC Owner in lieu of such redemption. In addition, the Corporation’s board of directors may, at its option, instead of the foregoing redemptions or exchanges of LLC Interests, cause the Corporation to make a cash payment equal to the volume weighted average market price of one share of Class A common stock for each LLC Interest redeemed or exchanged (subject to customary adjustments, including for stock splits, stock dividends and reclassifications) in accordance with the terms of the TWM LLC Agreement.

Issuance and Cancellation of Common Stock

· As a result of the Refinitiv Contribution, the Corporation received 96,933,192 LLC Interests and the Refinitiv Direct Owner received 96,933,192 shares of Class B common stock.

· The Corporation issued 20,000,000 shares of Class C common stock and 105,289,005 shares of Class D common stock to the Original LLC Owners that received LLC Interests on a one-to-one basis with the number of LLC Interests they owned immediately following the amendment and restatement of the TWM LLC Agreement for nominal consideration (the Corporation subsequently cancelled 9,993,731 shares of such Class C common stock and 36,006,269 shares of such Class D common stock in connection with the Corporation’s purchase of LLC Interests from certain of the Bank Stockholders using the net proceeds of the IPO).

Following the completion of the Reorganization Transactions, including the IPO and the application of the proceeds therefrom as described above, (i) the investors in the IPO collectively owned 46,000,000 shares of Class A common, representing 2.7% of the combined voting power of all of the Corporation’s common stock and, through the Corporation’s ownership of LLC Interests, 20.7% of the economic interest in TWM LLC; (ii) the Refinitiv Direct Owner owned 96,933,192 shares of Class B common stock, representing 56.4% of the combined voting power of all of the Corporation’s common stock and, through the Corporation’s ownership of LLC Interests, 43.6% of the economic interest in TWM LLC; (iii) the Refinitiv LLC Owner owned 22,988,329 shares of Class D common stock, representing 13.4% of the combined voting power of all of the Corporation’s common stock, and 22,988,329 LLC Interests, representing 10.3% of the economic interest in TWM LLC, (iv) the Continuing LLC Owners (other than the Refinitiv LLC Owner) collectively owned 10,006,269 shares of Class C common stock and 46,294,407 shares of Class D common stock, representing 27.5% of the combined voting power of all of the Corporation’s common stock, and 56,300,676 LLC Interests, representing 25.3% of the economic interest in TWM LLC; and (v) the Corporation owned 142,933,192 LLC Interests, representing 64.3% of the economic interest in TWM LLC.

9.          Income Taxes

The Company's effective tax rate was 17.5% and 14.1% for the three months ended September 30, 2019 and 2018, respectively, and 15.6% and 8.4% for the nine months ended September 30, 2019 and 2018, respectively. The increase in the effective tax rate for the three months and nine months ended September 30, 2019 was primarily due to the Reorganization Transactions. Prior to the Reorganization Transactions, income taxes consisted only of business taxes incurred by TWM LLC and certain subsidiaries for business conducted in certain state, local and foreign jurisdictions as well as federal, state and local taxes for certain subsidiaries that are taxed as corporations for U.S. tax purposes. As a result of the Reorganization Transactions, the Corporation is subject to U.S. federal, state and local income taxes with respect to its taxable income, including its allocable share of any taxable income of TWM LLC, and is taxed at prevailing corporate tax rates. The Company’s actual effective tax rate will be impacted by the Corporation’s ownership share of TWM LLC, which will increase over time as the Continuing LLC Owners redeem or exchange their LLC Interests for shares of Class A common stock or Class B common stock, as applicable, or the Corporation purchases LLC Interests from the Continuing LLC Owners.

The Company's consolidated effective tax rate will vary from period to period depending on redemptions, exchanges or purchases of LLC Interests as described above, changes in the geographic mix of its earnings and changes in tax legislation and tax rates.

The Company expects to obtain an increase in its share of the tax basis of the assets of TWM LLC when LLC Interests are redeemed or exchanged by the Continuing LLC Owners and in connection with certain other qualifying transactions. This increase in tax basis may have the effect of reducing the amounts that the Corporation would otherwise pay in the future to various tax authorities. Pursuant to the Tax Receivable Agreement, the Corporation is required to make cash payments to the Continuing LLC Owners equal to 50% of the amount of U.S. federal, state and local income or franchise tax savings, if any, that the Corporation actually realizes (or in some circumstances are deemed to realize) as a result of certain future tax benefits to which we may become entitled. The Corporation expects to benefit from the remaining 50% of tax benefits, if any, that the Corporation may actually realize. See Note 10 – Tax Receivable Agreement. As a result of the IPO, the Company assumed a tax benefit of $93.2 million, primarily due to an increase in amortizable tax basis that will be amortized primarily over 15 years pursuant to Section 197 of the Internal Revenue Code of 1986, as amended, offset by other factors. The tax benefit has been recognized in deferred tax asset on the September 30, 2019 consolidated statement of financial condition.

As a result of the Refinitiv Contribution, the Company assumed the tax liabilities of the contributed entity. The contributed entity is under audit by the State of New Jersey for the tax years 2012-2015 and is appealing a tax assessment from an audit by the State of New Jersey for the tax years 2008-2011. At September 30, 2019, the tax liability related to the Refinitiv Contribution is $2.8 million and is included within accounts payable, accrued expenses and other liabilities on the consolidated statement of financial condition.  The Company is indemnified by Refinitiv for tax liabilities that were assumed by the Company as a result of the Refinitiv Contribution. See Note 14 – Related Party Transactions.

Stock-Based Compensation Plans

13.          Stock-Based Compensation Plans

The Company maintains a stock-based incentive plan (the “PRSU Plan”) which provides for the grant of performance-based restricted share units (“PRSUs”) to encourage employees of the Company to participate in the long-term success of the Company.

PRSUs generally vest in the third plan year following the year of grant and are equity-settled in shares of Class A common stock (except as described below). The outstanding PRSUs vest on January 1, 2020, 2021 and 2022.  The number of PRSUs initially awarded is subsequently adjusted (upward or downward) by a performance modifier, based on the financial performance of the Company in the year of the grant.  If an employee’s employment with the Company is terminated, subject to certain exceptions, all unvested PRSUs are forfeited.

The following table summarizes information for equity-settled PRSUs of the Company (in thousands, except weighted average grant date fair value per unit):

	Successor		Successor
	Three Months		Nine Months

Weighted-average grant date fair value per unit	$	21.65	$	21.65
Total fair value of vested PRSUs	$	—	$	—

The Company previously granted cash-settled PRSUs, some of which are still outstanding and are accounted for as liability awards. The Company measures the cost of employee services received in exchange for the award based on the fair value of the Company and the value of accumulated dividend rights associated with each award. The fair value of that award is remeasured subsequently at each reporting date through to settlement. Changes in the award's fair value during the requisite service period is recognized as compensation cost over that period.

The following table summarizes information for cash-settled PRSUs of the Company (in thousands, except weighted average fair value per unit):

The Company maintains the Option Plan which provides for the grant of stock options. Prior to the IPO, the Company awarded options to management and other employees under the Option Plan. Each option vests one half based solely on the passage of time and one half only if the Company achieves certain performance targets. The time vesting portion of the options has a graded vesting schedule with vesting dates of January 1, 2019, 2020, 2021 and 2022, with accelerated vesting for time-based options with vesting dates of January 1, 2021 and 2022 upon the completion of an initial public offering.

In accounting for the options issued under the Option Plan, the Company measures and recognizes compensation expense for all awards based on their estimated fair values measured as of the grant date. These options are exercisable only any time following the closing of an initial public offering or during a 15‑day period following a change in control of the Company (and certain other sales of equity by the Company’s shareholders). Costs related to these options are recognized as an expense in the consolidated statements of income over the requisite service period, when exercisability is considered probable, with an offsetting increase to additional paid-in capital. As a result, expense recognition commenced upon the completion of the IPO, with $18.9 million recognized as compensation expense related to these options immediately upon the completion of the IPO.

The following table summarizes information for options of the Company (in thousands, except weighted average fair value per unit):

	Successor		Successor		Predecessor		Predecessor

17.          Commitments and Contingencies

In the normal course of business, the Company enters into user agreements with its dealers which provide the dealers with indemnification from third parties in the event that the electronic marketplaces of the Company infringe upon the intellectual property or other proprietary right of a third party. The Company's exposure under these user agreements is unknown as this would involve estimating future claims against the Company which have not yet occurred. However, based on its experience, the Company expects the risk of a material loss to be remote.

The Company has been named as a defendant, along with other financial institutions, in antitrust class actions (consolidated into two actions) relating to trading practices in United States Treasury securities auctions. The Company has filed a motion to dismiss the actions, believes it has substantial defenses to the other plaintiff's claims and intends to defend itself vigorously. Additionally, the Company was dismissed from a class action relating to an interest rate swaps matter in 2017, but that matter continues against the remaining defendant financial institutions.

The Company is a co-defendant in a matter relating to the distribution of financial strength ratings over the Company's trading platform to one of its customers. The matter alleges that while certain business units of the client were licensed to receive the data via the Company's platform, the data was also distributed without authorization to certain end clients of the customer. The plaintiff claims to have suffered approximately $80 million in damages and also seeks punitive damages, attorneys' fees and costs. In September 2019, the Court dismissed some, but not all, of plaintiff’s claims, and rejected plaintiff’s damages theory on which it relied to support its claims for approximately $80 million in damages. The Company intends to continue to vigorously defend what the Company believes to be meritless claims.

The Company records its best estimate of a loss, including estimated defense costs, when the loss is considered probable and the amount of such loss can be reasonably estimated. Based on its experience, the Company believes that the amount of damages claimed in a legal proceeding is not a meaningful indicator of the potential liability. At this time, the Company cannot reasonably predict the timing or outcomes of, or estimate the amount of loss, or range of loss, if any, related to its pending legal proceedings, including the matters described above, and therefore does not have any contingency reserves established for any of these matters.

Revolving Credit Facility

On April 8, 2019, the Company entered into a five year, $500 million senior secured revolving credit facility (“Credit Facility”) with a syndicate of banks. The Credit Facility provides additional borrowing capacity to be used to fund ongoing working capital needs, letters of credit and for general corporate purposes, including potential future acquisitions and expansions.

Under the terms of the credit agreement that governs the Credit Facility, borrowings under the Credit Facility bear interest at a rate equal to, at the Company’s option, either (a) a base rate equal to the greatest of (i) the administrative agent’s prime rate, (ii) the federal funds effective rate plus ½ of 1.0% and (iii) one month LIBOR plus 1.0%, in each case plus 0.75%, or (b) LIBOR plus 1.75%, subject to a 0.00% floor. The credit agreement also includes a commitment fee of 0.25% for available but unborrowed amounts and other administrative fees that are payable quarterly. The Credit Facility is available until April 2024, provided the Company is in compliance with all covenants. Financial covenant requirements include maintaining minimum ratios related to interest coverage and leverage.

As of September 30, 2019, there were no amounts outstanding under the Credit Facility.

14.          Related Party Transactions

The Company enters into transactions with Refinitiv and its affiliates which are considered to be related party transactions. The Company also enters into transactions with the Bank Stockholders and their respective affiliates. Prior to the Reorganization Transactions, the Bank Stockholders were collectively considered to be related parties of the Company. As a result of the Reorganization Transactions, they are no longer considered to be related parties. As a result, the related party transactions listed below include transactions with affiliates of Refinitiv for all periods presented and only includes transactions with affiliates of the Bank Stockholders for pre-IPO periods.

At September 30, 2019 and December 31, 2018, the following balances with such affiliates were included in the consolidated statements of financial condition in the following line items (in thousands):

(1) For pre-IPO periods, represents fees and commissions from affiliates of the Bank Stockholders.

(2) The Company maintains a market data license agreement with Refinitiv (TR in the predecessor period). Under the agreement, the Company delivers to Refinitiv certain market data feeds which Refinitiv redistributes to its customers. The Company earns license fees and royalties for these feeds.

(3) For pre-IPO periods, represents interest income from money market funds invested with and savings accounts deposited with affiliates of the Bank Stockholders.

(4) The Company maintains a shared services agreement with Refinitiv (TR in the predecessor period). Under the terms of the agreement, Refinitiv provides the Company with certain real estate, payroll, benefits administration, insurance, content, financial reporting and tax support.

The Company reimburses affiliates of Refinitiv (TR in the predecessor period) for expenses paid on behalf of the Company for various services including salaries and bonuses, marketing, professional fees, communications, data costs and certain other administrative services. For the three and nine months ended September 30, 2019, the Company reimbursed such affiliates approximately $1.2 million and $5.5 million, respectively, for these expenses. For the three and nine months ended September 30, 2018, the Company reimbursed such affiliates approximately $0.3 million and $28.7 million, respectively, for these expenses.

The Company is indemnified by Refinitiv for any tax liabilities that existed in the entity contributed by Refinitiv as a result of the Refinitiv Contribution.  At September 30, 2019, $2.7 million is included in other assets on the September 30, 2019 consolidated statement of financial condition related to this indemnification.

During 2014, the Company issued Class A Shares and unvested Class P-1(A) Shares to some of the Bank Stockholders as a result of a $120.0 million capital contribution.  In connection with this investment, employees invested $5.3 million in the Company and were issued Class C Shares and unvested Class P-1(C) Shares.  Certain Class P-1(A) Shares and Class P-1(C) Shares vested on July 31, 2018, based on a formula determined by the Company’s new credit platforms’ revenues and any remaining unvested Class P-1(A) Shares and Class P-1(C) Shares were cancelled and as a result  no contingent consideration has been recognized related to these shares subsequent to that date.  The Company recognized contingent consideration for the nine months ended September 30, 2018 of $26.8 million (which included a reversal of contingent consideration of $2.5 million for the three months ended September 30, 2018), relating to these shares, which is included in net revenue on the consolidated statements of income.

18.          Earnings Per Share

In April 2019, the Company completed the Reorganization Transactions and the IPO, which, among other things, resulted in the Corporation becoming the successor of TWM LLC for financial reporting purposes. As a result, earnings per share information for the pre-IPO period is not comparable to earnings per share information for the post-IPO period.  Thus, earnings per share information is being presented separately for the pre-IPO and post-IPO periods.

The following table summarizes the basic and diluted earnings per share calculations for Tradeweb Markets LLC (pre-IPO period):

For the three and nine months ended September 30, 2019, there were approximately 247,491 and 126,667 shares, respectively, underlying equity-settled PRSUs and options that were anti-dilutive and thus excluded from the computation of diluted earnings per share. For the three and nine months ended September 30, 2018, there were approximately 2,798,674 and 5,444,566 shares, respectively, related to the contingent consideration payable that were anti-dilutive and thus excluded from the computation of diluted earnings per share.

LLC Interests held by the Continuing LLC Owners are redeemable in accordance with the TWM LLC Agreement, at the election of such holders, for shares of Class A or Class B common stock of Tradeweb Markets Inc. After evaluating the potential dilutive effect under the if-converted method, the 79,289,005 LLC Interests for the assumed exchange of non-controlling interests were determined to be anti-dilutive and thus were excluded from the computation of diluted earnings per share for the post-IPO periods.

Shares of Class C and Class D common stock do not have economic rights in Tradeweb Markets Inc. and, therefore, are not participating securities for purposes of the computation of earnings per share.

Tax Receivable Agreement

Tax Receivable Agreement

10.          Tax Receivable Agreement

In connection with the Reorganization Transactions, the Corporation entered into the Tax Receivable Agreement with TWM LLC and the Continuing LLC Owners, which provides for the payment by the Corporation to a Continuing LLC Owner of 50% of the amount of U.S. federal, state and local income or franchise tax savings, if any, that the Corporation actually realizes (or in some circumstances is deemed to realize) as a result of (i) increases in the tax basis of TWM LLC’s assets resulting from (a) the purchase of LLC Interests from such Continuing LLC Owner, including with the net proceeds from the IPO and any future offering or (b) redemptions or exchanges by such Continuing LLC Owner of LLC Interests for shares of Class A common stock or Class B common stock or for cash, as applicable, and (ii) certain other tax benefits related to the Corporation making payments under the Tax Receivable Agreement. Payments under the Tax Receivable Agreement are made annually based on the actual tax savings realized by the Corporation in its previous tax year.

In connection with the IPO, the Company recorded an initial liability of $171.4 million related to its projected obligations under the Tax Receivable Agreement with respect to LLC Interests that were purchased by the Corporation using the net proceeds of the IPO.

The Corporation accounts for the income tax effects resulting from taxable redemptions or exchanges of LLC Interests by the Continuing LLC Owners for shares of Class A common stock or Class B common stock or cash, as the case may be, and purchases by the Corporation of LLC Interests from the Continuing LLC Owners by recognizing an increase in deferred tax assets, based on enacted tax rates at the date of each redemption or exchange, as the case may be. Further, the Corporation evaluates the likelihood that it will realize the benefit represented by the deferred tax asset, and, to the extent that the Corporation estimates that it is more likely than not that it will not realize the benefit, it reduces the carrying amount of the deferred tax asset with a valuation allowance.

The impact of any changes in the projected obligations under the Tax Receivable Agreement as a result of changes in the geographic mix of the Company’s earnings, changes in tax legislation and tax rates or other factors that may impact the Corporation’s tax savings will be reflected in income before taxes on the consolidated statement of income in the period in which the change occurs.

Significant Accounting Policies

Significant Accounting Policies

2.          Significant Accounting Policies

The following is a summary of significant accounting policies:

Basis of Accounting

The consolidated financial statements have been presented in conformity with accounting principles generally accepted in the United States of America. All adjustments, which are, in the opinion of management, necessary to a fair statement of the results for the interim periods presented, are normal and recurring in nature. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and the difference may be material to the consolidated financial statements.

Basis of Presentation and Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

As discussed in Note 1—Organization, as a result of the Reorganization Transactions, Tradeweb Markets Inc. consolidates TWM LLC and TWM LLC is considered to be the predecessor to Tradeweb Markets Inc. for financial reporting purposes. As a result, the consolidated financial statements for periods prior to the Reorganization Transactions have been adjusted to combine the previously separate entities for presentation purposes. However, Tradeweb Markets Inc. had no business transactions or activities and no substantial assets or liabilities prior to the Reorganization Transactions. As such, for periods prior to the completion of the Reorganization Transactions, the consolidated financial statements represent the historical financial condition and results of operations of TWM LLC and its subsidiaries. For periods after the completion of the Reorganization Transactions, the consolidated financial statements represent the financial condition and results of operations of the Company and report a non-controlling interest related to the LLC Interests held by the Continuing LLC Owners.

Cash and Cash Equivalents

Cash and cash equivalents consists of cash and highly liquid investments (such as short-term money market instruments) with original maturities of less than three months.

Allowance for Doubtful Accounts

The Company continually monitors collections and payments from its clients and maintains an allowance for doubtful accounts. The allowance for doubtful accounts is based upon the historical collection experience and specific collection issues that have been identified. Additions, if any, to the allowance for doubtful accounts are charged to bad debt expense, which is included in general and administrative expenses on the consolidated statements of income.

Furniture, Equipment, Purchased Software and Leasehold Improvements

Furniture, equipment, purchased software and leasehold improvements are carried at cost less accumulated depreciation. Depreciation for furniture, equipment and purchased software, including the allocated fair value of assets as a result of pushdown accounting (see Note 3 – Pushdown Accounting), is computed on a straight-line basis over the estimated useful lives of the related assets, ranging from three to seven years. Leasehold improvements are amortized over the lesser of the estimated useful lives of the leasehold improvements or the remaining term of the lease for office space.

Furniture, equipment, purchased software and leasehold improvements are tested for impairment whenever events or changes in circumstances suggest that an asset’s carrying value may not be fully recoverable in accordance with Accounting Standards Codification (“ASC”) 360.

Software Development Costs

The Company capitalizes costs associated with the development of internal use software at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed, in accordance with ASC 350. The Company capitalizes employee compensation and related benefits and third party consulting costs incurred during the application development stage which directly contribute to such development. Such costs are amortized on a straight-line basis over three years. Costs capitalized as part of the pushdown accounting allocation (see Note 3 – Pushdown Accounting) are amortized over nine years. The Company reviews the amounts capitalized for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable, or that their useful lives are shorter than originally expected. Non-capitalized software costs and routine maintenance costs are expensed as incurred.

Intangible Assets

Intangible assets with a finite life are amortized over the estimated lives, ranging from seven to sixteen years, in accordance with ASC 350. Intangible assets subject to amortization are tested for impairment whenever events or changes in circumstances suggest that an asset's or asset group's carrying value may not be fully recoverable in accordance with ASC 360. Intangible assets with an indefinite useful life are tested for impairment at least annually. An impairment loss is recognized if the sum of the estimated discounted cash flows relating to the asset or asset group is less than the corresponding book value.

Goodwill

Goodwill is the excess of the fair value of the Company above the fair value accounting basis of the net assets and liabilities of the Company under pushdown accounting. Goodwill is also the cost of acquired companies in excess of the fair value of identifiable net assets at the acquisition date. Goodwill is not amortized, but in accordance with ASC 350, goodwill is tested for impairment annually and between annual tests whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. Goodwill is tested at the reporting unit level, which is defined as an operating segment or one level below the operating segment. An impairment loss is recognized if the estimated fair value of a reporting unit is less than its net book value. Such loss is calculated as the difference between the estimated fair value of goodwill and its carrying value.

In 2019, the Company changed the annual date on which goodwill is tested for impairment from July 1st to October 1st to align with the annual impairment testing date of the Company’s Parent. This change did not accelerate, delay, avoid or cause an impairment charge, nor did this change result in adjustments to any previously issued financial statements. Goodwill was last assessed on October 1, 2018 in connection with the Refinitiv Transaction and the application of pushdown accounting.  See Note 3 – Pushdown Accounting.

Deferred IPO and Follow-On Offering Costs

In 2018 and the third quarter of 2019, the Company began incurring costs in connection with the filing of a Registration Statement on Form S-1 for an IPO and a Registration Statement on Form S-1 for a follow-on offering, respectively, which are deferred in other assets in accordance with ASC 505-10-25 in the consolidated statements of financial condition. IPO and follow-on offering costs consist of legal, accounting, and other costs directly related to the Company’s efforts to raise capital. As of September 30, 2019, $15.9 million of deferred costs related to the IPO were reclassified from other assets to additional paid-in capital and $0.7 million of deferred costs related to the follow-on offering were included in other assets, in each case on the consolidated statements of financial condition.  See Note 11 – Stockholders’ Equity and Note 21 – Subsequent Events.

Translation of Foreign Currency

Revenues and expenses denominated in foreign currencies are translated at the rate of exchange prevailing at the transaction date. Assets and liabilities denominated in foreign currencies are translated at the rate prevailing at the consolidated statements of financial condition date. Foreign currency re-measurement gains or losses on transactions in nonfunctional currencies are recognized in the consolidated statements of income. Gains or losses on translation in the financial statements of a non-U.S. operation, when the functional currency is other than the U.S. dollar, are included as a component of comprehensive income.

Income Tax

The Corporation is subject to U.S. federal, state and local income taxes with respect to its taxable income, including its allocable share of any taxable income of TWM LLC, and is taxed at prevailing corporate tax rates. TWM LLC is a multiple member limited liability company taxed as a partnership and accordingly any taxable income generated by TWM LLC is passed through to and included in the taxable income of its members, including the Corporation, on a pro rata basis. Income taxes also include unincorporated business taxes on income earned or losses incurred for conducting business in certain state and local jurisdictions, income taxes on income earned or losses incurred in foreign jurisdictions on certain operations and federal and state income taxes on income earned or losses incurred, both current and deferred, on subsidiaries that are taxed as corporations for U.S. tax purposes.

The Company records deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. The Company measures deferred taxes using the enacted tax rates and laws that will be in effect when such temporary differences are expected to reverse. Based on the weight of the positive and negative evidence considered, management believes that it is more likely than not that the Company will be able to realize its deferred tax assets in the future, therefore, no valuation allowance is necessary.

The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process whereby (i) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (ii) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

The Company recognizes interest and penalties related to income taxes within the provision for income taxes in the consolidated statements of income. Accrued interest and penalties are included within accounts payable, accrued expenses and other liabilities in the consolidated statements of financial condition.

The Company has elected to treat taxes due on future U.S. inclusions in taxable income under the global intangible low-taxed income (“GILTI”) provision of the Tax Cuts and Jobs Act as a current period expense when incurred.

Revenue Recognition

The Company earns transaction fees from transactions executed on the Company’s trading platforms through various fee plans. Transaction fees are generated both on a variable and fixed price basis and vary by geographic region, product type and trade size. For variable transaction fees, the Company charges clients fees based on the mix of products traded and the volume of transactions executed. Transaction fee revenue is recorded at a point in time when the trade occurs and is generally billed monthly.

The Company earns subscription fees from granting access to institutional investors to the Company's electronic marketplaces. Subscription fees are recognized into income in the period that access is provided on a monthly basis. Also included in subscription fees are viewer fees earned monthly from institutional investors accessing fixed income market data. The frequency of subscription fee billings varies from monthly to annually, depending on contract terms. Fees received by the Company which are not yet earned are included in deferred revenue on the consolidated statements of financial condition until the revenue recognition criteria has been met.

The Company earns commission revenue from its electronic and voice brokerage services on a riskless principal basis. Riskless principal revenues are derived on matched principal transactions where revenues are earned on the spread between the buy and sell price of the transacted product. Securities transactions and related commission income for brokerage transactions are recognized and recorded on a trade-date basis. Commission revenue is collected by the Company when the trade settles or is billed monthly.

The Company earns fees from Refinitiv, formerly TR in the predecessor periods, relating to the sale of market data to Refinitiv, which redistributes that data. Included in these fees, which are billed quarterly, are real-time market data fees which are recognized in the period that the data is provided, generally on a monthly basis and historical data sets which are recognized when the historical data set is provided to Refinitiv.

On January 1, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers, using the modified retrospective approach. The adoption of ASU 2014-09 did not have a material impact on the measurement or recognition of revenue in any prior reporting periods.  However, subsequent to the adoption, the Company was required to make significant judgements for the Refinitiv market data fees.  Significant judgements used in accounting for this contract include:

· The provision of real-time market data feeds and annual historical data sets are distinct performance obligations.

· The performance obligations under this contract are recognized over time from the initial delivery of the data feeds or each historical data set until the end of the contract term.

· Determining the transaction price for the performance obligations by using a market assessment analysis. Inputs in this analysis include a consultant study which determined the overall value of the Company's market data and pricing information for historical data sets provided by other companies.

Some revenues earned by the Company have fixed fee components, such as monthly minimums or fixed monthly fees, and variable components, such as transaction based fees. The breakdown of revenues between fixed and variable revenues, in thousands, for the three and nine months ended September 30, 2019 and 2018 is as follows:

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718. ASC 718 focuses primarily on accounting for a transaction in which an entity obtains employee services in exchange for stock-based payments. Under ASC 718, the stock-based payments received by the employees of the Company are accounted for either as equity awards or as liability awards.

As an equity award, the Company measures and recognizes the cost of employee services received in exchange for awards of equity instruments based on their estimated fair values measured as of the grant date. These costs are recognized as an expense over the requisite service period, with an offsetting increase to additional paid-in capital.

As a liability award, the cost of employee services received in exchange for an award of equity instruments is generally measured based on the grant-date fair value of the award. The fair value of that award is remeasured subsequently at each reporting date through the settlement in accordance with ASC 505. Changes in the equity instrument's fair value during the requisite service period are recognized as compensation cost over that period.

For periods following the Reorganization Transactions and the IPO, the fair value of new equity instrument grants is determined based on the price of the Company’s Class A common stock on the grant date.

Under ASC 718, the grant-date fair value of stock-based awards that do not require future service (i.e., vested awards) are expensed immediately. The grant-date fair value of stock-based awards that require future service, and are graded-vesting awards, are amortized over the relevant service period on a straight-line basis, with each tranche separately measured. The grant-date fair value of stock-based awards that require both future service and the achievement of Company performance-based conditions, are amortized over the relevant service period for the performance-based condition. If in a reporting period it is determined that the achievement of a performance target for a performance-based tranche is not probable, then no expense is recognized for that tranche and any expenses already recognized relating to that tranche in prior reporting periods are reversed in the current reporting period.

Prior to the IPO, the Company awarded options to management and other employees (collectively, the “Special Option Award”) under the Amended and Restated Tradeweb Markets Inc. Option Plan (the “Option Plan”). In accounting for the options issued under the Option Plan, compensation expense is measured and recognized for all awards based on their estimated fair values measured as of the grant date. Costs related to these options are recognized as an expense in the consolidated statements of income over the requisite service period, with an offsetting increase to additional paid-in capital. The non-cash stock-based compensation expense associated with the Special Option Award began being expensed in the second quarter of 2019 and will continue to be expensed over the following three years.

Determining the appropriate fair value model and calculating the fair value of the stock-based awards requires the input of highly subjective assumptions, including the expected life of the stock-based awards and the stock price volatility. The Company uses the Black-Scholes pricing model to value some of its stock-based awards.

Earnings Per Share

Basic earnings per share is computed by dividing the net income attributable to the Company's shares by the weighted-average number of the Company's shares outstanding during the period. For purposes of computing diluted earnings per share, the weighted-average number of the Company’s shares reflects the dilutive effect that could occur if securities that qualify as participating securities were converted into or exchanged or exercised for TWM LLC’s shares, in the pre-IPO period, and the Corporation’s Class A or Class B common stock, in the post-IPO period, using the treasury stock method, as applicable.

Shares of Class C and Class D common stock do not have economic rights in Tradeweb Markets Inc. and, therefore, are not participating securities for purposes of the computation of earnings per share.

Fair Value Measurement

The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). Instruments that the Company owns (long positions) are marked to bid prices, and instruments that the Company has sold, but not yet purchased (short positions) are marked to offer prices. Fair value measurements do not include transaction costs.

The fair value hierarchy under ASC 820 prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under ASC 820 are described below:

Basis of Fair Value Measurement

Level 1:Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: Quoted prices in markets that are not considered to be active or financial instruments for which all significant inputs are observable, either directly or indirectly;

Level 3: Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Recent Accounting Pronouncements – Not Yet Adopted

In June 2016, the FASB issued ASU 2016‑13, Financial Instruments – Credit Losses. The ASU provides new guidance for estimating credit losses on certain types of financial instruments by introducing an approach based on expected losses. This ASU is applicable for the Company in the fiscal year beginning January 1, 2020 and requires a modified retrospective method of adoption. The Company is currently in the planning and analysis phase, which involves documenting in-scope financial assets and understanding and leveraging existing credit loss estimation processes.

The Company does not anticipate the adoption of this ASU to have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017‑04, Intangibles – Goodwill and Other. The ASU simplifies the quantitative goodwill impairment test by eliminating the second step of the test. Under this ASU, impairment will be measured by comparing the estimated fair value of the reporting unit with its carrying value. The ASU is applicable for the Company in the fiscal year beginning January 1, 2020. The Company does not anticipate the adoption of this ASU to have a material impact on the Company's consolidated financial statements.

Leases

6.          Leases

Effective January 1, 2019, the Company adopted ASC 842, Leases. This standard requires the Company to recognize a right-of-use asset and a lease liability for all leases with an initial term in excess of twelve months. The Company accounts for an option to extend a lease when the option is reasonably certain to be exercised. The asset reflects the present value of unpaid lease payments coupled with initial direct costs, prepaid lease payments and lease incentives. The amount of the lease liability is calculated as the present value of unpaid lease payments. The Company adopted ASC 842 using a modified retrospective approach and did not restate comparative periods. The Company elected to take the package of practical expedients allowing the Company to not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for any existing leases.  The Company has elected to account for nonlease components in a contract as part of the single lease component to which they are related.

Significant assumptions and judgements in calculating the right-of-use assets and lease liability include the determination of the applicable borrowing rate for each lease.

On January 1, 2019, upon the adoption of ASC 842, the Company recorded, for office space and data center leases in the U.S. and U.K., right-of-use assets of $34.8 million, lease liabilities of $39.6 million and eliminated deferred rent of $4.9 million. The leases have initial lease terms ranging from three to 11 years.
