Item 1. – Financial Statements

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of TD Ameritrade Holding Corporation

Results of Review of Interim Financial Statements

We have reviewed the accompanying condensed consolidated balance sheet of TD Ameritrade Holding Corporation and subsidiaries (the Company) as of March 31, 2020, the related condensed consolidated statements of income, comprehensive income and stockholders' equity for the three-month and six-month periods ended March 31, 2020 and 2019, the condensed consolidated statements of cash flows for the six-month periods ended March 31, 2020 and 2019, and the related notes (collectively referred to as the "condensed consolidated interim financial statements"). Based on our reviews, we are not aware of any material modifications that should be made to the condensed consolidated interim financial statements for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of September 30, 2019, the related consolidated statements of income, comprehensive income, stockholders' equity and cash flows for the year then ended, and the related notes (not presented herein); and in our report dated November 15, 2019, we expressed an unqualified audit opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of September 30, 2019, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

These financial statements are the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the SEC and the PCAOB. We conducted our review in accordance with the standards of the PCAOB. A review of interim financial statements consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

TD AMERITRADE HOLDING CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

For the Three Month and Six Month Periods Ended March 31, 2020 and 2019

(Unaudited)

1. Basis of Presentation, Organization and Recent Accounting Pronouncements

Basis of Presentation

The condensed consolidated financial statements include the accounts of TD Ameritrade Holding Corporation (the "Parent") and its wholly-owned subsidiaries (collectively, the "Company"). Intercompany balances and transactions have been eliminated.

These financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and, in the opinion of management, reflect all adjustments, which are all of a normal recurring nature, necessary to present fairly the financial position, results of operations and cash flows for the periods presented in conformity with U.S. generally accepted accounting principles ("GAAP"). These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's annual report filed on Form 10-K for the fiscal year ended September 30, 2019.

Organization

The Company provides securities brokerage services, including trade execution, clearing services and margin lending, through its broker-dealer subsidiaries; futures and foreign exchange trade execution services through its futures commission merchant ("FCM") and forex dealer member ("FDM") subsidiary; and bundled retirement plan solutions to plan sponsors and their advisors through its state-chartered trust company subsidiary. The Company also provides cash sweep and deposit account products through third-party relationships, including relationships with affiliates.

In March 2020, the World Health Organization declared the spread of the coronavirus ("COVID-19") a worldwide pandemic. The pandemic has negatively impacted the global economy and is affecting financial markets, causing significant market volatility and erosion of market value. The Company is actively monitoring the impact of COVID-19 on its business, financial condition, liquidity, operations, employees, clients and business partners. In response to the pandemic and for the protection of the Company's employees, clients and business partners, the Company has implemented remote work arrangements for nearly 100% of its employees, has restricted business travel and has temporarily closed its retail branches. To date, with the Company's ability to meet a vast majority of its clients' needs through its technology-based platforms and services, these arrangements have not materially affected the Company's ability to maintain its business operations, including the operation of financial reporting systems, internal control over financial reporting, and disclosure controls and procedures. Based on information available as of the date of this report, the Company does not expect the pandemic to have a material adverse impact to its results of operations and cash flows in the near term; although, given the daily evolution of the pandemic and the global responses to curb its spread, the Company is currently unable to estimate the long-term effects of the pandemic on its financial condition, results of operations or cash flows.

On November 24, 2019, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with The Charles Schwab Corporation ("Schwab") and Americano Acquisition Corp., a wholly-owned subsidiary of Schwab. The Merger Agreement was included as Exhibit 2.1 to the Company's Form 8-K filed with the SEC on November 27, 2019. Upon the terms and subject to the conditions of the Merger Agreement, Americano Acquisition Corp. will merge with and into the Company (the "Merger"), with the Company surviving as a wholly-owned subsidiary of Schwab. Pursuant to and subject to the terms of the Merger Agreement, at the effective time of the Merger, each share of the Company's common stock, $0.01 par value, issued and outstanding immediately prior to the effective time of the Merger (other than treasury shares held by the Company and certain shares held by Schwab), will be converted into the right to receive 1.0837 shares of Schwab's voting common stock, $0.01 par value (the "Merger Consideration"); however, if the Merger Consideration issuable in respect of shares of the Company's common stock owned by The Toronto-Dominion Bank ("TD") and its affiliates as of immediately prior to the effective time of the Merger, together with any other shares of Schwab common stock then owned by TD and its affiliates, would equal a number of shares of Schwab common stock exceeding 9.9% (or such lower percentage of shares of Schwab common stock as the Federal Reserve Board permits TD to acquire in the Merger consistent with a determination that TD does not control Schwab for purposes of the Bank Holding Company Act of 1956, as amended, or the Home Owners' Loan Act of 1933, as amended) of the issued and outstanding shares of Schwab common stock as of immediately following the effective time of the Merger, then TD will receive one share of nonvoting common stock of Schwab in lieu of each such excess share of Schwab common stock. Completion of the Merger is subject to certain conditions, including obtaining the necessary approvals from stockholders of both the Company and Schwab, the satisfaction of certain regulatory approvals and other customary closing conditions. The parties expect the transaction to close during the second half of calendar year 2020.

For the three and six months ended March 31, 2020, the Company incurred $8 million and $34 million, respectively, of costs related to the proposed Merger, which are included in professional services on the Condensed Consolidated Statements of Income.

Recently Adopted Accounting Pronouncements

ASU 2016-02 — On October 1, 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, Leases, by applying the standard at the adoption date, recognizing a cumulative-effect adjustment to the opening balance of retained earnings. As a result, restated financial information and the additional disclosures required under the new standard will not be provided for the comparative periods presented. The new guidance requires quantitative and qualitative disclosures that provide information about the amounts related to leasing arrangements recorded in the condensed consolidated financial statements. The Company elected a package of practical expedients available under the new guidance, which allows an entity to not reassess prior conclusions related to existing contracts containing leases, lease classification and initial direct costs. In addition, the Company has elected to apply the short-term lease exception for lease arrangements with a maximum term of 12 months or less. Upon the adoption of the lease standard, the Company recognized a right-of-use ("ROU") asset and a lease liability on the Condensed Consolidated Balance Sheet related to non-cancelable operating leases.

The cumulative effect of the changes made to the Company's Condensed Consolidated Balance Sheet as of October 1, 2019 for the adoption of ASU 2016-02 were as follows (dollars in millions):

	Balance at September 30, 2019		Adjustments from Adoption of ASU 2016-02					Balance at October 1, 2019
Assets:
Other assets	$	308	$	341		(1	)	$	649
Liabilities:
Accounts payable and other liabilities	884		342			(2	)	1,226
Stockholders' Equity:
Retained earnings	8,580		(1		)	(3	)	8,579

(1) Adjustments include the following: (a) an increase of $347 million for the recognition of the ROU asset and (b) a decrease of $6 million for lease payments made to lessors at or before the commencement date, which were reclassified to the ROU lease liability upon the adoption of the lease standard.

(2) Adjustments include the following: (a) an increase of $379 million for the recognition of the ROU lease liability and (b) decreases of $30 million for deferred rent and $7 million related to the early termination of lease obligations, which were reclassified to the ROU asset upon the adoption of the lease standard.

(3) Represents the impact of a lease obligation which had no future benefit upon the adoption of the lease standard.

The adoption of this standard did not have a material impact on the Company's results of operations or cash flows. See Note 6 for additional information regarding the Company's operating leases.

Recently Issued Accounting Pronouncements

ASU 2020-04 — In March 2020, the Financial Accounting Standards Board ("FASB") issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting if certain criteria are met. The amendments in ASU 2020-04 provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. This guidance is effective immediately and the amendments may be applied prospectively through December 31, 2022. The Company is evaluating the guidance and the potential impact of adopting ASU 2020-04 on its condensed consolidated financial statements.

ASU 2019-12 — In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The amendments in ASU 2019-12 simplify the accounting for income taxes by removing certain exceptions to the general principles in Accounting Standards Codification ("ASC") Topic 740, Income Taxes. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. ASU 2019-12 will be effective for the Company's fiscal year beginning October 1, 2021, with early adoption permitted. The transition requirements are dependent upon each amendment within this update and will be applied either prospectively or retrospectively. The Company does not expect this ASU to have a material impact on its condensed consolidated financial statements.

ASU 2016-13 — In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments. The main objective of ASU 2016-13 is to provide financial statement users with more decision-useful information about an entity's

12

expected credit losses on financial instruments and other commitments to extend credit at each reporting date. To achieve this objective, the amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to develop credit loss estimates. Subsequent to issuing ASU 2016-13, the FASB has issued additional standards for the purpose of clarifying certain aspects of ASU 2016-13, as well as providing codification improvements and targeted transition relief under the standard. The subsequently issued ASUs have the same effective date and transition requirements as ASU 2016-13. ASU 2016-13 will be effective for the Company's fiscal year beginning October 1, 2020, using a modified retrospective approach. Early adoption is permitted. The Company is currently assessing the impact this ASU will have on its condensed consolidated financial statements.

6. Leases

The Company enters into various non-cancelable operating leases for certain facilities, including corporate offices, retail branches and data centers. The Company determines if an arrangement is a lease at inception. Operating leases with an initial term of 12 months or less are not recorded on the balance sheet and the related lease expense is recognized on a straight-line basis over the lease term. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement or remeasurement date of a lease based on the present value of lease payments over the lease term. The Company utilizes an incremental borrowing rate to determine the present value of lease payments for each lease, as the lease agreements do not provide an implicit rate. The estimated incremental borrowing rate reflects a secured rate and is based on the term of the lease and the interest rate environment at the lease commencement or remeasurement date. Operating lease ROU assets include (1) lease payments made at or before the commencement date and (2) initial indirect costs; and exclude lease incentives. The Company's lease terms may include options to extend or terminate the lease. Only those renewal and termination options which the Company is reasonably certain of exercising are included in the calculation of the lease liability.

Senior Notes — As of March 31, 2020 and September 30, 2019, the Company had $3.55 billion aggregate principal amount of unsecured Senior Notes (together, the "Senior Notes"). The fixed rate and variable rate Senior Notes pay interest semi-annually and quarterly, respectively, in arrears. Key information about the Senior Notes outstanding is summarized in the following table (dollars in millions):

Description	Date Issued	Maturity Date	Aggregate Principal	Interest Rate
2021 Notes	October 30, 2018	November 1, 2021	$600	Variable
2022 Notes	March 4, 2015	April 1, 2022	$750	2.950%
2024 Notes	October 30, 2018	April 1, 2024	$400	3.750%
2025 Notes	October 17, 2014	April 1, 2025	$500	3.625%
2027 Notes	April 27, 2017	April 1, 2027	$800	3.300%
2029 Notes	August 13, 2019	October 1, 2029	$500	2.750%

Lines of Credit — TD Ameritrade Clearing, Inc. ("TDAC"), a clearing broker-dealer subsidiary of the Company, utilizes secured uncommitted lines of credit for short-term liquidity. Under these secured uncommitted lines, TDAC borrows on either a demand or short-term basis from two unaffiliated banks and pledges client margin securities as collateral. Advances under the secured uncommitted lines are dependent on TDAC having acceptable collateral as determined by each secured uncommitted credit agreement. At March 31, 2020, the terms of the secured uncommitted credit agreements do not specify borrowing limits. The availability of TDAC's secured uncommitted lines is subject to approval by the individual banks each time an advance is requested and may be denied. There were no borrowings outstanding under the secured uncommitted lines of credit as of March 31, 2020 and September 30, 2019.

Securities Sold Under Agreements to Repurchase (repurchase agreements) — Under repurchase agreements, the Company receives cash from the counterparty and provides U.S. government debt securities as collateral. The Company's repurchase agreements generally mature between seven and 90 days following the transaction date and are accounted for as secured borrowings. The remaining contractual maturities of the repurchase agreements with outstanding balances as of March 31, 2020 were less than seven days. The weighted average interest rate on the balances outstanding as of March 31, 2020 was 0.19%. There were no borrowings outstanding under repurchase agreements as of September 30, 2019. See "General Contingencies" in Note 9 for a discussion of the potential risks associated with repurchase agreements and how the Company mitigates those risks.

Fair Value Hedging — The Company is exposed to changes in the fair value of its fixed-rate Senior Notes resulting from interest rate fluctuations. To hedge a vast majority of this exposure, the Company has entered into fixed-for-variable interest rate swaps on each of the 2022 Notes, 2025 Notes, 2027 Notes and 2029 Notes (together, the "Hedged Senior Notes"). Each fixed-for-variable interest rate swap has a notional amount and a maturity date matching the aggregate principal amount and maturity date, respectively, for each of the respective Hedged Senior Notes.

The interest rate swaps effectively change the fixed-rate interest on the Hedged Senior Notes to variable-rate interest. Under the terms of the interest rate swap agreements, the Company receives semi-annual fixed-rate interest payments based on the same rates applicable to the Hedged Senior Notes, and makes quarterly variable-rate interest payments based on three-month LIBOR plus (1) 0.9486% for the swap on the 2022 Notes, (2) 1.1022% for the swap on the 2025 Notes, (3) 1.0340% for the swap on the 2027 Notes and (4) 1.2000% for the swap on the 2029 Notes. As of March 31, 2020, the weighted average effective interest rate on the aggregate principal balance of the Senior Notes was 2.92%.

The interest rate swaps are accounted for as fair value hedges and qualify for the shortcut method of accounting. Changes in the payment of interest resulting from the interest rate swaps are recorded in interest on borrowings on the Condensed Consolidated Statements of Income. Changes in fair value of the interest rate swaps are completely offset by changes in fair value of the related notes, resulting in no effect on net income. The following table summarizes gains and losses resulting from changes in the fair value of interest rate swaps designated as fair value hedges and the hedged fixed-rate debt for the periods indicated (dollars in millions):

	Three Months Ended March 31,						Six Months Ended March 31,
	2020			2019			2020			2019

Balance Sheet Impact of Hedging Instruments — The following table summarizes the classification and the fair value of outstanding derivatives designated as hedging instruments on the Condensed Consolidated Balance Sheets (dollars in millions):

	March 31, 2020		September 30, 2019
Pay-variable interest rate swaps designated as fair value hedges:
Other assets	$	193	$	71
Accounts payable and other liabilities	$	—	$	(3	)

The interest rate swaps are subject to counterparty credit risk. Credit risk is managed by limiting activity to approved counterparties that meet a minimum credit rating threshold, by entering into credit support agreements, or by utilizing approved central clearing counterparties registered with the Commodity Futures Trading Commission ("CFTC"). The interest rate swaps require daily collateral coverage, in the form of cash or U.S. Treasury securities, for the aggregate fair value of the interest rate swaps (including accrued interest). As of March 31, 2020 and September 30, 2019, the pay-variable interest rate swap counterparties had pledged $219 million and $86 million of collateral, respectively, to the Company in the form of cash. A liability for collateral pledged to the Company in the form of cash is recorded in accounts payable and other liabilities on the Condensed Consolidated Balance Sheets. As of September 30, 2019, the Company had pledged $3 million of collateral to the pay-variable interest rate swap counterparties in the form of cash. An asset for collateral pledged to the swap counterparties in the form of cash is recorded in other receivables on the Condensed Consolidated Balance Sheets.

TD Ameritrade Holding Corporation Senior Revolving Credit Facility — On April 21, 2017, the Parent entered into a credit agreement consisting of a senior unsecured committed revolving credit facility in the aggregate principal amount of $300 million (the "Parent Revolving Facility"). The maturity date of the Parent Revolving Facility is April 21, 2022. The obligations under the Parent Revolving Facility are not guaranteed by any subsidiary of the Parent.

The applicable interest rate under the Parent Revolving Facility is calculated as a per annum rate equal to, at the option of the Parent, (1) LIBOR plus an interest rate margin ("Parent Eurodollar loans") or (2) (i) the highest of (x) the prime rate, (y) the federal funds effective rate (or, if the federal funds effective rate is unavailable, the overnight bank funding rate) plus 0.50% or (z) the eurodollar rate assuming a one-month interest period plus 1.00%, plus (ii) an interest rate margin ("ABR loans"). The interest rate margin ranges from 0.875% to 1.50% for Parent Eurodollar loans and from 0% to 0.50% for ABR loans, determined by reference to the Company's public debt ratings. The Parent is obligated to pay a commitment fee ranging from 0.08% to 0.20% on any unused amount of the Parent Revolving Facility, determined by reference to the Company's public debt ratings. There were no borrowings outstanding under the Parent Revolving Facility as of March 31, 2020 and September 30, 2019. As of March 31, 2020, the interest rate margin would have been 1.125% for Parent Eurodollar loans and 0.125% for ABR loans, and the commitment fee was 0.125%, each determined by reference to the Company's public debt ratings.

TD Ameritrade Clearing, Inc. Senior Revolving Credit Facilities — As of March 31, 2020, TDAC had access to two senior unsecured committed revolving credit facilities with an aggregate principal amount of $1.45 billion, consisting of a $600 million (the "$600 Million Revolving Facility") and an $850 million (the "$850 Million Revolving Facility") senior revolving facility (together, the "TDAC Revolving Facilities"). The maturity dates of the $600 Million Revolving Facility and the $850 Million Revolving Facility are April 21, 2022 and May 14, 2020, respectively. On April 21, 2020, TDAC entered into an amendment to the $850 million Revolving Facility, which provides for a senior unsecured revolving credit facility in the aggregate principal amount of $850 million that matures on April 20, 2021 (the "Amended Credit Agreement"). For additional information regarding the Amended Credit Agreement, see Note 16, Subsequent Event.

The applicable interest rate under each of the TDAC Revolving Facilities is calculated as a per annum rate equal to, at the option of TDAC, (1) LIBOR plus an interest rate margin ("TDAC Eurodollar loans") or (2) the federal funds effective rate plus an interest rate margin ("Federal Funds Rate loans"). The interest rate margin ranges from 0.75% to 1.25% for both TDAC Eurodollar loans and Federal Funds Rate loans, determined by reference to the Company's public debt ratings. TDAC is obligated to pay commitment fees ranging from 0.07% to 0.175% and from 0.06% to 0.125% on any unused amounts of the $600 Million Revolving Facility and the $850 Million Revolving Facility, respectively, each determined by reference to the Company's public debt ratings. There were no borrowings outstanding under the TDAC Revolving Facilities as of March 31, 2020 and September 30, 2019. As of March 31, 2020, the interest rate margin under the TDAC Revolving Facilities would have been 1.00% for both TDAC Eurodollar loans and Federal Funds Rate loans, determined by reference to the Company's public debt ratings. As of March 31, 2020, the commitment fees under the $600 Million Revolving Facility and the $850 Million Revolving Facility were 0.10% and 0.08%, respectively, each determined by reference to the Company's public debt ratings.

In addition, under the alternative method, a broker-dealer may not repay any subordinated borrowings, pay cash dividends or make any unsecured advances or loans to its parent company or employees if such payment would result in net capital of less than (1) 5% of aggregate debit balances or (2) 120% of its minimum dollar requirement.

TD Ameritrade Futures & Forex LLC ("TDAFF"), the Company's FCM and FDM subsidiary registered with the CFTC, is subject to CFTC Regulations 1.17 and 5.7 under the Commodity Exchange Act, administered by the CFTC and the National Futures Association. As an FCM, TDAFF is required to maintain minimum adjusted net capital under CFTC Regulation 1.17 of the greater of (1) $1.0 million or (2) its futures risk-based capital requirement, equal to 8% of the total risk margin requirement for all futures and options on futures positions carried by the FCM in client and nonclient accounts. As an FDM, TDAFF is also subject to the net capital requirements under CFTC Regulation 5.7, which requires TDAFF to maintain minimum adjusted net capital of the greater of (1) any amount required under CFTC Regulation 1.17 as described above or (2) $20.0 million plus 5% of all foreign exchange liabilities owed to forex clients in excess of $10.0 million.

9. Commitments and Contingencies

Legal and Regulatory Matters

Order Routing Matters — In 2014, five putative class action complaints were filed regarding TD Ameritrade, Inc.'s routing of client orders and one putative class action was filed regarding Scottrade, Inc.'s routing of client orders. Five of the six cases were dismissed and the United States Court of Appeals, 8th Circuit, affirmed the dismissals in those cases that were appealed. The one remaining case is Roderick Ford (replacing Gerald Klein) v. TD Ameritrade Holding Corporation, et al., Case No. 8:14CV396 (U.S. District Court, District of Nebraska). In the remaining case, plaintiff alleges that, when routing client orders to various market centers, defendants did not seek best execution, and instead routed clients' orders to market venues that paid TD Ameritrade, Inc. the most money for order flow. Plaintiff alleges that defendants made misrepresentations and omissions regarding the Company's order routing practices. The complaint asserts claims of violations of Section 10(b) and 20 of the Exchange Act and SEC Rule 10b-5. The complaint seeks damages, injunctive relief, and other relief. Plaintiff filed a motion for class certification, which defendants opposed. On July 12, 2018, the Magistrate Judge issued findings and a recommendation that plaintiff's motion for class certification be denied. Plaintiff filed objections to the Magistrate Judge's findings and recommendation, which defendants opposed. On September 14, 2018, the District Judge sustained plaintiff's objections, rejected the Magistrate Judge's recommendation and granted plaintiff's motion for class certification. On September 28, 2018, defendants filed a petition requesting that the U.S. Court of Appeals, 8th Circuit, grant an immediate appeal of the District Court's class certification decision. The U.S. Court of Appeals, 8th Circuit, granted defendants' petition on December 18, 2018. Briefing on the appeal is complete. The Securities Industry and Financial Markets Association and the U.S. Chamber of Commerce have filed amicus curiae briefs in support of the Company's appeal. The Company intends to vigorously defend against this lawsuit and is unable to predict the outcome or the timing of the ultimate resolution of the lawsuit, or the potential loss, if any, that may result.

Litigation Relating to the Merger — Six complaints have been filed by purported stockholders of the Company challenging the Merger. The first, a putative class action complaint, was filed by Michael Kent in the United States District Court for the District of Delaware and is captioned Kent v. TD Ameritrade Holding Corporation et al., case number 1:20-cv-00388. The second complaint, filed in the United States District Court for the District of Delaware by Shiva Stein individually, is captioned Stein v. TD Ameritrade Holding Corporation et al., case number 1:20-cv-00410. The third complaint, filed in the United States District Court for the District of New Jersey by Marc Roth individually, is captioned Roth v. TD Ameritrade Holding Corporation et al., case number 2:20-cv-03425. The fourth complaint, filed in the United States District Court for the District of New Jersey by Harold Litwin individually, is captioned Litwin v. TD Ameritrade Holding Corporation et al., case number 2:20-cv-03569. The fifth, a putative class action complaint, filed in the United States District Court for the District of New Jersey by Audrey Bernstein, is captioned Bernstein v. TD Ameritrade Holding Corporation et al., case number 2:20-cv-03695. The sixth complaint, filed in the United States District Court for the Southern District of New York by Glenn Garrison individually, is captioned Garrison v. TD Ameritrade Holding Corporation et al., case number 1:20-cv-02850. The complaints generally allege, among other things, that the defendants named therein authorized the filing of a materially incomplete and misleading registration statement with the SEC. Among other remedies, the complaints seek to enjoin the stockholder vote at the TD Ameritrade special meeting to be held to approve the Merger and related matters and the closing of the Merger, as well as costs and attorneys' fees. The Company believes that the complaints are without merit but is unable to predict the outcome of the ultimate resolution of the lawsuits, or the potential loss, if any, that may result. In addition, a purported stockholder of the Company has made a demand pursuant to Section 220 of the Delaware General Corporation Law to inspect certain books and records of the Company relating to the proposed Merger. There can be no assurances that additional complaints or demands will not be filed or made with respect to the Merger.

Other Legal and Regulatory Matters — The Company is subject to a number of other lawsuits, arbitrations, claims and other legal proceedings in connection with its business. Some of these legal actions include claims for substantial or unspecified compensatory and/or punitive damages. In addition, in the normal course of business, the Company discusses matters with its regulators raised during regulatory examinations or otherwise subject to their inquiry. These matters could result in censures, fines, penalties or other sanctions. ASC 450, Loss Contingencies, governs the recognition and disclosure of loss contingencies, including potential losses from legal and regulatory matters. ASC 450 categorizes loss contingencies using three terms based on the likelihood of occurrence of events that result in a loss: "probable" means that "the future event or events are likely to occur;" "remote" means that "the chance of the future event or events occurring is slight;" and "reasonably possible" means that "the chance of the future event or events occurring is more than remote but less than likely." Under ASC 450, the Company accrues for losses that are considered both probable and reasonably estimable. The Company may incur losses in addition to the amounts accrued where the losses are greater than estimated by management, or for matters for which an unfavorable outcome is considered reasonably possible, but not probable.

The Company estimates that the aggregate range of reasonably possible losses in excess of amounts accrued is from $0 to $65 million as of March 31, 2020. This estimated aggregate range of reasonably possible losses is based upon currently available information for those legal and regulatory matters in which the Company is involved, taking into account the Company's best estimate of reasonably possible losses for those matters as to which an estimate can be made. For certain matters, the Company does not believe an estimate can currently be made, as some matters are in preliminary stages and some matters have no specific

20

amounts claimed. The Company's estimate involves significant judgment, given the varying stages of the proceedings and the inherent uncertainty of predicting outcomes. The estimated range will change from time to time as the underlying matters, stages of proceedings and available information change. Actual losses may vary significantly from the current estimated range.

The Company believes, based on its current knowledge and after consultation with counsel, that the ultimate disposition of these legal and regulatory matters, individually or in the aggregate, is not likely to have a material adverse effect on the financial condition or cash flows of the Company. However, in light of the uncertainties involved in such matters, the Company is unable to predict the outcome or the timing of the ultimate resolution of these matters, or the potential losses, fines, penalties or equitable relief, if any, that may result, and it is possible that the ultimate resolution of one or more of these matters may be material to the Company's results of operations for a particular reporting period.

Income Taxes

The Company's federal and state income tax returns are subject to examination by taxing authorities. Because the application of tax laws and regulations to many types of transactions is subject to varying interpretations, amounts reported in the condensed consolidated financial statements could be significantly changed at a later date upon final determinations by taxing authorities.

General Contingencies

In the ordinary course of business, there are various contingencies that are not reflected in the condensed consolidated financial statements. These include the Company's broker-dealer and FCM/FDM subsidiaries' client activities involving the execution, settlement and financing of various client securities, options, futures and foreign exchange transactions. These activities may expose the Company to credit risk and losses in the event the clients are unable to fulfill their contractual obligations.

The Company extends margin credit and leverage to its clients. In margin transactions, the Company extends credit to the client, subject to various regulatory and internal margin requirements, collateralized by cash and securities in the client's account. In connection with these activities, the Company also routes client orders for execution and clears client transactions involving the sale of securities not yet purchased ("short sales"). Such margin-related transactions may expose the Company to credit risk in the event a client's assets are not sufficient to fully cover losses that the client may incur. Leverage involves securing a large potential future obligation with a lesser amount of collateral. The risks associated with margin credit and leverage increase during periods of rapid market movements, or in cases where leverage or collateral is concentrated and market movements occur. In the event the client fails to satisfy its obligations, the Company has the authority to liquidate certain positions in the client's account(s) at prevailing market prices in order to fulfill the client's obligations. However, during periods of rapid market movements, clients who utilize margin credit or leverage and who have collateralized their obligations with securities may find that the securities have a rapidly depreciating value (or increasing value with respect to short positions) and may not be sufficient to cover their obligations in the event of liquidation. The Company seeks to mitigate the risks associated with its client margin and leverage activities by requiring clients to maintain margin collateral in compliance with various regulatory and internal guidelines. The Company monitors required margin levels throughout each trading day and, pursuant to such guidelines, requires clients to deposit additional collateral, or to reduce positions, when necessary.

The Company contracts with unaffiliated FCM, FDM and broker-dealer entities to clear and execute futures, options on futures and foreign exchange transactions for its clients. This can result in concentrations of credit risk with one or more of these counterparties. This risk is partially mitigated by the counterparties' obligation to comply with rules and regulations governing FCMs, FDMs and broker-dealers in the United States. These rules generally require maintenance of net capital and segregation of client funds and securities. In addition, the Company manages this risk by requiring credit approvals for counterparties and by utilizing account funding and sweep arrangement agreements that generally specify that all client cash in excess of futures funding requirements be transferred back to the clients' securities brokerage accounts at the Company on a daily basis.

The Company loans securities temporarily to other broker-dealers in connection with its broker-dealer business. The Company receives cash as collateral for the securities loaned. Increases in securities prices may cause the market value of the securities loaned to exceed the amount of cash received as collateral. In the event the counterparty to these transactions does not return the loaned securities, the Company may be exposed to the risk of acquiring the securities at higher prevailing market prices in order to satisfy its client obligations. The Company mitigates this risk by requiring credit approvals for counterparties, by monitoring the market value of securities loaned on a daily basis and requiring additional cash as collateral when necessary, and by participating in a risk-sharing program offered through the Options Clearing Corporation ("OCC").

The Company borrows securities temporarily from other broker-dealers in connection with its broker-dealer business. The Company deposits cash as collateral for the securities borrowed. Decreases in securities prices may cause the market value of the securities borrowed to fall below the amount of cash deposited as collateral. In the event the counterparty to these transactions does not return the cash deposited, the Company may be exposed to the risk of selling the securities at lower prevailing market prices. The Company mitigates this risk by requiring credit approvals for counterparties, by monitoring the collateral values on

21

a daily basis and requiring collateral to be returned by the counterparties when necessary, and by participating in a risk-sharing program offered through the OCC.

The Company transacts in reverse repurchase agreements (securities purchased under agreements to resell) in connection with its broker-dealer business. The Company's policy is to take possession or control of securities with a market value in excess of the principal amount loaned, plus accrued interest, in order to collateralize resale agreements. The Company monitors the market value of the underlying securities that collateralize the related receivable on resale agreements on a daily basis and may require additional collateral when deemed appropriate.

The Company utilizes securities sold under agreements to repurchase (repurchase agreements) to finance its short-term liquidity and capital needs. Under these agreements, the Company receives cash from the counterparties and provides U.S. Treasury securities as collateral, allowing the counterparties the right to sell or repledge the collateral. These agreements expose the Company to credit losses in the event the counterparties cannot meet their obligations. The Company mitigates this risk by requiring credit approvals for counterparties, by monitoring the market value of pledged securities owned on a daily basis and requiring the counterparties to return cash or excess collateral pledged when necessary.

The Company has accepted collateral in connection with client margin loans and securities borrowed. Under applicable agreements, the Company is generally permitted to repledge securities held as collateral and use them to enter into securities lending arrangements. The following table summarizes the fair values of client margin securities and stock borrowings that were available to the Company to utilize as collateral on various borrowings or for other purposes, and the amount of that collateral loaned or repledged by the Company (dollars in billions):

	March 31, 2020		September 30, 2019
Client margin securities	$	22.1	$	28.6
Stock borrowings	0.3		1.9
Total collateral available	$	22.4	$	30.5
Collateral loaned	$	1.6	$	3.2
Collateral repledged	7.7		4.6
Total collateral loaned or repledged	$	9.3	$	7.8

The Company is subject to cash deposit and collateral requirements with clearinghouses based on its clients' trading activity. The following table summarizes cash deposited with and securities pledged to clearinghouses by the Company (dollars in millions):

Assets	Condensed Consolidated Balance Sheet Classification	March 31, 2020		September 30, 2019
Cash	Receivable from brokers, dealers and clearing organizations	$	1,158	$	545
U.S. government debt securities	Securities owned, at fair value	181		168
Total		$	1,339	$	713

The Company manages its sweep program through off-balance sheet arrangements with TD and unaffiliated third-party depository financial institutions (together, the "Sweep Program Counterparties"). The sweep program is offered to eligible clients whereby the client's uninvested cash is swept into FDIC-insured (up to specified limits) money market deposit accounts at the Sweep Program Counterparties. The Company earns revenue on client cash at the Sweep Program Counterparties based on the return of floating-rate and fixed-rate notional investments. The Company designates amounts and maturity dates for the fixed-rate notional investments within the sweep program portfolios, subject to certain limitations. In the event the Company instructs the Sweep Program Counterparties to withdraw a fixed-rate notional investment prior to its maturity, the Company may be required to reimburse the Sweep Program Counterparties for any losses incurred as a result of the early withdrawal. In order to mitigate the risk of potential loss due to an early withdrawal of fixed-rate notional investments, the Company maintains a certain level of short-term floating-rate investments within the sweep program portfolios to meet client cash demands. See "Insured Deposit Account Agreement" in Note 15 for a description of the sweep arrangement between the Company and TD.

22

Guarantees

The Company is a member of and provides guarantees to securities clearinghouses and exchanges in connection with client trading activities. Under related agreements, the Company is generally required to guarantee the performance of other members. Under these agreements, if a member becomes unable to satisfy its obligations to the clearinghouse, other members would be required to meet shortfalls. The Company's liability under these arrangements is not quantifiable and could exceed the cash and securities it has posted to the clearinghouse as collateral. However, the likelihood that the Company would be required to make payments under these agreements is considered remote. Accordingly, no contingent liability is carried on the Condensed Consolidated Balance Sheets for these guarantees.

The Company clears its clients' futures and options on futures transactions on an omnibus account basis through unaffiliated FCMs. The Company also contracts with an external provider to facilitate foreign exchange trading for its clients. The Company has agreed to indemnify these unaffiliated FCMs and the external provider for any loss that they may incur from the client transactions introduced to them by the Company.

See "Insured Deposit Account Agreement" in Note 15 for a description of the guarantees included in that agreement.

10. Fair Value Disclosures

Fair Value Measurement — Definition and Hierarchy

ASC 820-10, Fair Value Measurement, defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date.

ASC 820-10 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability, and are developed based on market data obtained from sources independent of the Company. Unobservable inputs reflect the Company's own assumptions about the assumptions other market participants would use in pricing the asset or liability, and are developed based on the best information available in the circumstances.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, as follows:

• Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. This category includes active exchange-traded funds, money market mutual funds, mutual funds and equity securities.

• Level 2 — Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Such inputs include quoted prices in markets that are not active, quoted prices for similar assets and liabilities in active and inactive markets, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means. This category includes most debt securities, U.S. government agency mortgage-backed securities, which consist of Ginnie Mae Conventional Residential Mortgages and Ginnie Mae Home Equity Conversion Mortgages, and other interest-sensitive financial instruments.

• Level 3 — Unobservable inputs for the asset or liability, where there is little, if any, observable market activity or data for the asset or liability.

Valuation Techniques

In general, and where applicable, the Company uses quoted prices in active markets for identical assets or liabilities to determine fair value. This pricing methodology applies to the Company's Level 1 assets and liabilities. If quoted prices in active markets for identical assets and liabilities are not available to determine fair value, then the Company uses quoted prices for similar assets and liabilities or inputs other than the quoted prices that are observable, either directly or indirectly. This pricing methodology applies to the Company's Level 2 assets and liabilities.

Level 2 Measurements:

Debt securities — Fair values for debt securities are based on prices obtained from an independent pricing vendor. The primary inputs to the valuation include quoted prices for similar assets in active markets, quoted prices for identical or similar assets in markets that are not active, contractual cash flows, benchmark yields and credit spreads. The Company validates the vendor pricing by periodically comparing it to pricing from another independent pricing service. The Company has not adjusted prices obtained from the independent pricing vendor for any periods presented in the condensed consolidated financial statements because no significant pricing differences have been observed.

U.S. government agency mortgage-backed securities — Fair values for mortgage-backed securities are based on prices obtained from an independent pricing vendor. The primary inputs to the valuation include quoted prices for similar assets in active markets and in markets that are not active, a market-derived prepayment curve, weighted average yields on the underlying collateral and spreads to benchmark indices. The Company validates the vendor pricing by periodically comparing it to pricing from two other

25

independent sources. The Company has not adjusted prices obtained from the independent pricing vendor for any periods presented in the condensed consolidated financial statements because no significant pricing differences have been observed.

Interest rate swaps — These derivatives are valued by the Company using a valuation model provided by a third-party service that incorporates interest rate yield curves, which are observable for substantially the full term of the contract. The valuation model is widely accepted in the financial services industry and does not involve significant judgment because most of the inputs are observable in the marketplace. Credit risk is not an input to the valuation because in each case the Company or counterparty has possession of collateral, in the form of cash or U.S. Treasury securities, in amounts equal to or exceeding the fair value of the interest rate swaps. The Company validates the third-party service valuations by comparing them to valuation models provided by the swap counterparties.

Level 3 Measurements:

The Company has no assets or liabilities classified as Level 3 of the fair value hierarchy.

Fair Value of Financial Instruments Not Recorded at Fair Value

Receivable from/payable to brokers, dealers and clearing organizations, receivable from/payable to clients, receivable from/payable to affiliates, other receivables and accounts payable and other liabilities are short-term in nature and accordingly are carried at amounts that approximate fair value. These financial instruments are recorded at or near their respective transaction prices and historically have been settled or converted to cash at approximately that value (categorized as Level 2 of the fair value hierarchy).

Cash and investments segregated and on deposit for regulatory purposes includes reverse repurchase agreements (securities purchased under agreements to resell). Reverse repurchase agreements are treated as collateralized financing transactions and are carried at amounts at which the securities will subsequently be resold, plus accrued interest. The Company's reverse repurchase agreements generally have a maturity of seven days and are collateralized by securities in amounts exceeding the carrying value of the resale agreements. Accordingly, the carrying value of reverse repurchase agreements approximates fair value (categorized as Level 2 of the fair value hierarchy). Cash and investments segregated and on deposit for regulatory purposes also includes cash held in demand deposit accounts and on deposit with futures commission merchants, for which the carrying values approximate the fair value (categorized as Level 1 of the fair value hierarchy). See Note 3 for a summary of cash and investments segregated and on deposit for regulatory purposes.

Securities sold under agreements to repurchase (repurchase agreements) included within other borrowings — Under repurchase agreements the Company receives cash from the counterparties and provides U.S. Treasury securities as collateral. The obligations to repurchase securities sold are reflected as a liability on the Condensed Consolidated Balance Sheets. Repurchase agreements are treated as collateralized financing transactions and are carried at amounts at which the securities will subsequently be repurchased, plus accrued interest. The Company's repurchase agreements are short-term in nature and accordingly the carrying value is a reasonable estimate of fair value (categorized as Level 2 of the fair value hierarchy).

Long-term debt — As of March 31, 2020, the Company's Senior Notes had an aggregate estimated fair value, based on quoted market prices (categorized as Level 1 of the fair value hierarchy), of approximately $3.58 billion, compared to the aggregate carrying value of the Senior Notes on the Condensed Consolidated Balance Sheet of $3.72 billion. As of September 30, 2019, the Company's Senior Notes had an aggregate estimated fair value, based on quoted market prices, of approximately $3.67 billion, compared to the aggregate carrying value of the Senior Notes on the Condensed Consolidated Balance Sheet of $3.59 billion.

11. Offsetting Assets and Liabilities

Substantially all of the Company's securities sold under agreements to repurchase (repurchase agreements), reverse repurchase agreements, securities borrowing and securities lending activity and derivative financial instruments are transacted under master agreements that may allow for net settlement in the ordinary course of business, as well as offsetting of all contracts with a given counterparty in the event of default by one of the parties. However, for financial statement purposes, the Company does not net balances related to these financial instruments.

The following tables present information about the potential effect of rights of setoff associated with the Company's recognized assets and liabilities as of March 31, 2020 and September 30, 2019 (dollars in millions):

(1) Effective October 3, 2019, the Company reduced its online exchange-listed stock, exchange traded funds (ETF) (domestic and Canadian) and option trade commissions from $6.95 to $0 per trade (plus $0.65 per contract and no exercise or assignment fees on option trades).

The amount of revenue recognized by the Company is measured based on the consideration specified in contracts with its clients. The Company recognizes revenue when a performance obligation is satisfied over time as the services are performed or at a point in time depending on the nature of the services provided as further discussed below.

Asset-Based Revenues

Asset-based revenues consists of bank deposit account fees, net interest revenue and investment product fees. The primary factors driving the Company's asset-based revenues are average balances and average rates. Average balances consist primarily of average client bank deposit account balances, average client margin balances, average segregated cash balances, average client credit balances, average fee-based investment balances and average securities borrowing and lending balances. Average rates consist of the average interest rates and fees earned and paid on such balances.

Bank deposit account fees

Bank deposit account fees consists of revenues earned and recognized over time resulting from a sweep program that is offered to eligible clients of the Company whereby clients' uninvested cash is swept off-balance sheet to FDIC-insured (up to specified limits) accounts with Sweep Program Counterparties participating in the program. These revenues are based on the return of floating-rate and fixed-rate notional investments, less the actual interest paid to clients and other applicable fees. Bank deposit account fees are collected from the Sweep Program Counterparties on a monthly basis. See "Insured Deposit Account Agreement" in Note 15 for a description of the sweep arrangement between the Company and TD.

Net interest revenue

Net interest revenue, which is generated from financial instruments covered by various other areas of GAAP, is not within the scope of ASC Topic 606, Revenue from Contracts with Customers, and is included in the table above to reconcile to net revenues disclosed within the Condensed Consolidated Statements of Income. Net interest revenue primarily consists of income generated by interest charged to clients on margin balances, net interest revenue from securities borrowed and securities loaned transactions and interest earned on client cash, net of interest paid to clients on their credit balances.

31

Investment product fees

Investment product fee revenue consists of revenues earned and recorded over time on client assets invested in money market mutual funds, other mutual funds and certain investment programs. Investment product fees also includes fees earned on client assets managed by independent registered investment advisors ("RIAs") utilizing the Company's trading and investing platforms. Investment product fees are collected from clients and RIAs on a monthly or quarterly basis. Primary revenue sources within investment product fees are described below.

The following tables present the significant components of investment product fees for the periods indicated (dollars in millions):

	Three Months Ended March 31,
	2020		2019
Investment product fees:
Mutual fund service fees	$	79	$	68
Investment program fees	63		61
Other	2		8
Total investment product fees	$	144	$	137

	Six Months Ended March 31,
	2020		2019
Investment product fees:
Mutual funds service fees	$	160	$	135
Investment program fees	127		129
Other	3		16
Total investment product fees	$	290	$	280

Mutual fund service fees includes shareholder services fees and SEC Rule 12b-1 service and distribution fees. Shareholder services fees are earned on the Company's client assets invested in money market mutual funds and other mutual funds for record-keeping and administrative services provided to these funds. The Company earns SEC Rule 12b-1 service and distribution fees for marketing and distribution services provided to these funds. The fees earned are based on contractual rates applied to the average daily net asset value of eligible shares of a respective fund held by the Company's clients. Shareholder services fees are earned over time and collected from the funds on a monthly or quarterly basis. SEC Rule 12b-1 fees are also earned over time and collected from the funds on a monthly or quarterly basis, as the variable consideration of a transaction price is no longer constrained and the value of consideration can be determined as discussed previously.

Investment program fees are earned through fees charged to clients enrolled in product offerings which are actively managed by TD Ameritrade Investment Management, LLC, a wholly-owned subsidiary of the Company. These fees are earned over time and are based on contractual rates applied to asset balances held by the Company's clients in these product offerings. Certain program fees are based on quarter-end balances and are collected from clients in advance, at the beginning of each calendar quarter. Revenues collected on a quarterly basis, less refunds for clients ceasing participation in the program, are recognized during the quarter as performance obligations are satisfied. Other program fees are based on average daily asset balances and collected from clients on a monthly basis.

The Company also earns investment program fees through referral and asset-based program fees on its client assets managed by independent RIAs utilizing the Company's platform. These fees are earned based on contractual rates applied to the client's average daily asset balances under management. Referral fees are earned over time and collected from the independent RIAs on a monthly or quarterly basis, as the variable consideration of a transaction price is no longer constrained and the value of consideration can be determined as discussed previously. Asset-based program fees are also earned over time and collected from the independent RIAs on a monthly or quarterly basis.

Transaction-Based Revenues

Transaction-based revenues primarily consists of order routing revenue and trading commissions earned on trade execution, net of promotional allowances. The primary factors driving the Company's transaction-based revenues are total trades and average commissions per trade. Commission rates are based on rates established by the Company, which vary by type of trade. Transaction-based revenues are earned and recognized at a point in time, on a trade-date basis, as clients execute trades. These trades are generally settled and trading commissions are collected from the Company's clients within one to two business days after the trade

32

date. Order routing revenues are generated from arrangements with market centers to receive cash payments and/or rebates in exchange for routing orders to these firms for execution and are generally collected from the market centers on a monthly basis. Securities owned by clients, including those that collateralize margin or similar transactions, are not reflected in the accompanying condensed consolidated financial statements.

Other Revenues

Other revenues primarily include proxy income, solicit and tender fees and other fees charged for ancillary services provided by the Company to its clients. In addition, other revenues include fair market value adjustments and gains/losses associated with investments held by the Company's broker-dealer subsidiaries. Other revenues generated from investments is covered by various other areas of GAAP, is not within the scope of ASC 606 and is included in the table above to reconcile to net revenues disclosed within the Condensed Consolidated Statements of Income. Proxy fee income is earned and collected at a point in time when the Company distributes proxy statements to its clients on behalf of a registrant and the revenue is based on the volume of proxies distributed and the rate per unit charged to each registrant. Solicit and tender fees are earned and collected from clients at a point in time when the Company has satisfied its obligation to maintain its client accounts holding securities affected by corporate actions.

Contract Balances

The following table presents the opening and closing balances of the Company's receivables from contracts with clients that are within the scope of ASC 606 on the Condensed Consolidated Balance Sheets (dollars in millions):

	Contract Balances
	Receivable from Clients		Receivable from Affiliates			Other Receivables		Total Receivables from Contracts with Clients
Opening balance, September 30, 2019	$	25	$	7		$	125	$	157
Closing balance, March 31, 2020	26		3			183		212
Increase (decrease)	$	1	$	(4	)	$	58	$	55

The difference between the opening and closing balances of the Company's total receivables from contracts with clients primarily results from the timing difference between the Company's performance and the receipt of payments. No other significant contract assets or liabilities exist as of March 31, 2020 and September 30, 2019.

Unsatisfied Performance Obligations

The Company does not have any unsatisfied performance obligations subject to a practical expedient election under ASC 606.

15. Related Party Transactions

Transactions with TD and its Affiliates

As a result of the Company's acquisition of TD Waterhouse Group, Inc. during fiscal year 2006, TD became an affiliate of the Company. TD owned approximately 43% of the Company's common stock as of March 31, 2020. Pursuant to the stockholders agreement between TD and the Company, TD has the right to designate five of the twelve members of the Company's board of directors. The Company transacts business and has extensive relationships with TD and certain of its affiliates. Transactions with TD and its affiliates are discussed and summarized below.

Insured Deposit Account Agreement

The Company is party to an insured deposit account ("IDA") agreement with TD Bank USA, N.A. ("TD Bank USA"), TD Bank, N.A. and TD. Under the IDA agreement, TD Bank USA and TD Bank, N.A. (together, the "TD Depository Institutions") make available to clients of the Company FDIC-insured (up to specified limits) money market deposit accounts as either designated sweep vehicles or as non-sweep deposit accounts. The Company provides marketing, recordkeeping and support services for the TD Depository Institutions with respect to the money market deposit accounts. In exchange for providing these services, the TD Depository Institutions pay the Company an aggregate marketing fee based on the weighted average yield earned on the client IDA assets, less the actual interest paid to clients, a servicing fee to the TD Depository Institutions and the cost of FDIC insurance premiums.

The current IDA agreement became effective as of January 1, 2013 and had an initial term expiring July 1, 2018. It is automatically renewable for successive five-year terms, provided that it may be terminated by either the Company or the TD Depository Institutions by providing written notice of non-renewal at least two years prior to the initial expiration date or the expiration date

33

of any subsequent renewal period. As of July 1, 2016, notice of non-renewal was not provided by either party; therefore, the IDA agreement was automatically renewed for an additional five-year term on July 1, 2018.

The fee earned on the IDA agreement is calculated based on two primary components: (1) the yield on fixed-rate notional investments, based on prevailing fixed rates for identical balances and maturities in the interest rate swap market (generally LIBOR-based) at the time such investments were added to the IDA portfolio (including any adjustments required to adjust the variable rate leg of such swaps to a one-month reset frequency and the overall swap payment frequency to monthly) and (2) the yield on floating-rate investments. As of March 31, 2020, the IDA portfolio was comprised of approximately 67% fixed-rate notional investments and 33% floating-rate investments.

The IDA agreement provides that the Company may designate amounts and maturity dates for the fixed-rate notional investments in the IDA portfolio, subject to certain limitations. For example, if the Company designates that $100 million of deposits be invested in 5-year fixed-rate investments, and on the day such investment is confirmed by the TD Depository Institutions the prevailing fixed yield for the applicable 5-year U.S. dollar LIBOR-based swaps is 1.45%, then the Company will earn a gross fixed yield of 1.45% on that portion of the portfolio (before any deductions for interest paid to clients, the servicing fee to the TD Depository Institutions and the cost of FDIC insurance premiums). In the event that (1) the federal funds effective rate is established at 0.75% or greater and (2) the rate on 5-year U.S. dollar interest rate swaps is equal to or greater than 1.50% for 20 consecutive business days, then the rate earned by the Company on new fixed-rate notional investments will be reduced by 20% of the excess of the 5-year U.S. dollar swap rate over 1.50%, up to a maximum of 0.10%.

The yield on floating-rate investments is calculated daily based on the greater of the following rates published by the Federal Reserve: (1) the interest rate paid by Federal Reserve Banks on balances held in excess of required reserve balances and contractual clearing balances under Regulation D and (2) the daily effective federal funds rate.

The interest rates paid to clients are set by the TD Depository Institutions and are not linked to any index. The servicing fee to the TD Depository Institutions under the IDA agreement is equal to 25 basis points on the aggregate average daily balance in the IDA accounts, subject to adjustment as it relates to deposits of less than or equal to $20 billion kept in floating-rate investments or in fixed-rate notional investments with a maturity of up to 24 months ("short-term fixed-rate investments"). For such floating-rate and short-term fixed-rate investments, the servicing fee is equal to the difference of the interest rate earned on the investments less the FDIC premiums paid (in basis points), divided by two. The servicing fee has a floor of 3 basis points (subject to adjustment from time to time to reflect material changes to the TD Depository Institutions' leverage costs) and a maximum of 25 basis points.

In the event the marketing fee computation results in a negative amount, the Company must pay the TD Depository Institutions the negative amount. This effectively results in the Company guaranteeing the TD Depository Institutions revenue equal to the servicing fee on the IDA agreement, plus the reimbursement of FDIC insurance premiums. The marketing fee computation under the IDA agreement is affected by many variables, including the type, duration, principal balance and yield of the fixed-rate and floating-rate investments, the prevailing interest rate environment, the amount of client deposits and the yield paid on client deposits. Because a negative marketing fee computation would arise only if there were extraordinary movements in many of these variables, the maximum potential amount of future payments the Company could be required to make under this arrangement cannot be reasonably estimated. Management believes the likelihood that the marketing fee calculation would result in a negative amount is remote. Accordingly, no contingent liability is carried on the Condensed Consolidated Balance Sheets for the IDA agreement. In the event the Company withdraws a notional investment prior to its maturity, the Company is required to reimburse the TD Depository Institutions an amount equal to the economic replacement value of the investment, as defined in the IDA agreement. See "General Contingencies" in Note 9 for a discussion of how the Company mitigates the risk of losses due to the early withdrawal of fixed-rate notional investments.

In addition, the Company has various other services agreements and transactions with TD and its affiliates. The following tables summarize revenues and expenses resulting from transactions with TD and its affiliates for the periods indicated (dollars in millions):

The following table summarizes the classification and amount of receivables from and payables to TD and its affiliates on the Condensed Consolidated Balance Sheets resulting from related party transactions (dollars in millions):

	March 31, 2020		September 30, 2019
Assets:
Receivable from brokers, dealers and clearing organizations	$	68	$	—
Receivable from affiliates	89		112
Liabilities:
Payable to brokers, dealers and clearing organizations	$	27	$	44
Payable to affiliates	5		5
Accounts payable and other liabilities	2		2

Receivables from and payables to brokers, dealers and clearing organizations primarily relate to securities borrowing and lending activity and are settled in accordance with customary contractual terms. Receivables from and payables to TD affiliates resulting from client cash sweep activity are generally settled in cash the next business day. Other receivables from and payables to affiliates of TD are generally settled in cash on a monthly basis.

TD, along with other financial institutions, is participating as a lender under the Parent Revolving Facility and the TDAC Revolving Facilities. For additional information regarding the Company's revolving facilities, see Note 7, Long-term Debt and Other Borrowings. As of March 31, 2020 and September 30, 2019, the total lending commitment received from TD under these credit facilities was $221 million.

16. Subsequent Event

On April 21, 2020, TDAC entered into an amendment to the $850 million Revolving Credit Facility, which provides for a senior unsecured revolving credit facility in the aggregate principal amount of $850 million that matures on April 20, 2021 (the "Amended Credit Agreement"). Borrowings under the Amended Credit Agreement may be used for working capital needs and for general corporate purposes.

The applicable interest rate under the Amended Credit Agreement is calculated as a per annum rate equal to, at the option of TDAC, (1) LIBOR plus an interest rate margin ("Amended Eurodollar loans") or (2) the federal funds effective rate plus an interest rate margin ("Amended Federal Funds Rate loans"). The interest rate margin will range from 1.00% to 1.50% for both Amended Eurodollar loans and Amended Federal Funds Rate loans, determined by reference to the Company's public debt ratings. TDAC will be obligated to pay a commitment fee ranging from 0.20% to 0.35% on any unused amount of the Amended Credit Agreement, determined by reference to the Company's public debt ratings.

The Amended Credit Agreement contains negative covenants that limit or restrict, subject to certain exceptions, the incurrence of liens, indebtedness of TDAC, changes in nature of business, mergers, consolidations, and the sale of all or substantially all of the assets of TDAC. TDAC is also required to maintain minimum consolidated tangible net worth and is required to maintain compliance with minimum regulatory net capital requirements. The Amended Credit Agreement also contains customary affirmative covenants, including, but not limited to, compliance with applicable law, payment of taxes, maintenance of insurance, preservation of corporate existence, keeping of proper books of record and account and maintenance of properties.

Item 2. - Management's Discussion and Analysis of Financial Condition and Results of Operations

Unless otherwise indicated, the terms "we," "us," "our" or "Company," or "TD Ameritrade" in this report refer to TD Ameritrade Holding Corporation and its wholly-owned subsidiaries.

The following discussion of the financial condition and results of operations of the Company should be read in conjunction with the Selected Financial Data and the Consolidated Financial Statements and Notes thereto included in the Company's annual report on Form 10-K for the fiscal year ended September 30, 2019, and the Condensed Consolidated Financial Statements and Notes thereto contained in this quarterly report on Form 10-Q.

This discussion contains forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Statements that are not historical facts, including statements about our beliefs and expectations, are forward-looking statements. Forward-looking statements include statements preceded by, followed by or that include the words "may," "could," "would," "should," "believe," "expect," "anticipate," "plan," "estimate," "target," "project," "intend" and similar words or expressions. In particular, forward-looking statements contained in this discussion include our expectations regarding: the impact of the pandemic on our financial condition, results of operations and cash flows; the effect of changes in interest rates on our net interest spread; the effect of client trading activity on our results of operations; the amount of our net revenues, including certain asset-based and trading metrics for the next two quarters of fiscal year 2020; the amounts of our total operating expenses; our effective income tax rate; our capital and liquidity needs and our plans to finance such needs; and our plans to return capital to stockholders through cash dividends.

In March 2020, the World Health Organization declared the spread of the coronavirus ("COVID-19") a worldwide pandemic. The pandemic has negatively impacted the global economy and is affecting financial markets, causing significant market volatility and erosion of market value. We are actively monitoring the impact of COVID-19 on our business, financial condition, liquidity, operations, employees, clients and business partners. In response to the pandemic and for the protection of our employees, clients and business partners, we have implemented remote work arrangements for nearly 100% of our employees, have restricted business travel and have temporarily closed our retail branches. To date, with our ability to meet a vast majority of our clients' needs through our technology-based platforms and services, these arrangements have not materially affected our ability to maintain our business operations. The impact of the pandemic on financial markets resulted in heightened client engagement during the second quarter of fiscal year 2020. Additionally, in response to the pandemic, during March 2020 the Federal Open Market Committee decreased the target range for the federal funds rate by 150 basis points (to between 0 to 0.25%). Based on information available as of the date of this report, we do not expect the pandemic to have a material adverse impact to our results of operations and cash flows in the near term; although, given the daily evolution of the pandemic and the global responses to curb its spread, we are currently unable to estimate the long-term effects of the pandemic on our financial condition, results of operations or cash flows.

On November 24, 2019, we entered into an Agreement and Plan of Merger (the "Merger Agreement") with The Charles Schwab Corporation ("Schwab") and Americano Acquisition Corp., a wholly-owned subsidiary of Schwab. The Merger Agreement was included as Exhibit 2.1 to the Company's Form 8-K filed with the Securities and Exchange Commission ("SEC") on November 27, 2019. Upon the terms and subject to the conditions of the Merger Agreement, Americano Acquisition Corp. will merge with and into the Company (the "Merger"), with the Company surviving as a wholly-owned subsidiary of Schwab. Pursuant to and subject to the terms of the Merger Agreement, our stockholders will receive 1.0837 shares of Schwab's voting common stock for each share of the Company's common stock (the "Merger Consideration"); however, if the Merger Consideration issuable in respect of shares of the Company's common stock owned by The Toronto-Dominion Bank ("TD") and its affiliates as of immediately prior to the effective time of the Merger, together with any other shares of Schwab common stock then owned by TD and its affiliates, would equal a number of shares of Schwab common stock exceeding 9.9% (or such lower percentage of shares of Schwab common stock as the Federal Reserve Board permits TD to acquire in the Merger consistent with a determination that TD does not control Schwab for purposes of the Bank Holding Company Act of 1956, as amended, or the Home Owners' Loan Act of 1933, as amended) of the issued and outstanding shares of Schwab common stock as of immediately following the effective time of the Merger, then TD will receive one share of nonvoting common stock of Schwab in lieu of each such excess share of Schwab common stock. Completion of the Merger is subject to certain conditions, including obtaining the necessary approvals from stockholders of both the Company and Schwab, the satisfaction of certain regulatory approvals and other customary closing conditions. The parties expect the transaction to close during the second half of calendar year 2020. For the three and six months ended March 31, 2020, we incurred $8 million and $34 million, respectively, of costs related to the proposed Merger, which are included in professional services on the Condensed Consolidated Statements of Income.

There are risks, uncertainties and assumptions that could cause our actual results or performance to differ materially from those contained in our forward-looking statements. Among the risks, uncertainties and assumptions that could cause our actual results or performance to differ materially from those contained in our forward-looking statements are the risks, uncertainties and assumptions disclosed under Part II, Item 1A. – "Risk Factors," of this quarterly report on Form 10-Q. We are also subject to the risks, uncertainties and assumptions disclosed under Item 1A. – "Risk Factors" of, and elsewhere in, our annual report on Form 10-K for the fiscal year ended September 30, 2019, including, among others, economic, social and political conditions and other securities industry risks; interest rate risks; liquidity risks; client and counterparty credit risks; our ability to introduce new products

36

and services and update or enhance existing products and services to remain competitive; clearing function risks; systemic risk; aggressive competition; information system risks, network security risks; investment advisory services risks; merger and acquisition risks; external service provider risks; employee misconduct risks; LIBOR phase-out risks; new laws, rules, regulations and regulatory guidance affecting our business; net capital requirements; extensive regulation and regulatory uncertainties; and litigation, investigations and proceedings involving our business, as well as the risk that our risk management practices may leave us exposed to unidentified or unanticipated risks. The forward-looking statements contained in this report speak only as of the date on which they were made. We undertake no obligation to publicly update or revise such statements, whether as a result of new information, future events or otherwise, except to the extent required by the federal securities laws.

The preparation of our financial statements requires us to make judgments and estimates that may have a significant impact upon our financial results. Note 1 of our Notes to Consolidated Financial Statements in our annual report on Form 10-K for the fiscal year ended September 30, 2019, contains a summary of our significant accounting policies, many of which require the use of estimates and assumptions. We believe that the following areas are particularly subject to management's judgments and estimates and could materially affect our results of operations and financial position: valuation of goodwill and acquired intangible assets; estimates of effective income tax rates, uncertain tax positions, deferred income taxes and related valuation allowances; and accruals for contingent liabilities. These areas are discussed in further detail under the heading "Critical Accounting Policies and Estimates" in Item 7 of our annual report on Form 10-K for the fiscal year ended September 30, 2019.

The term "GAAP" refers to U.S. generally accepted accounting principles. We utilize non-GAAP calculations of earnings before interest, taxes, depreciation and amortization ("EBITDA") and liquid assets. We believe that these non-GAAP measures may be useful in evaluating the operating performance and liquidity of the business. Reference to these non-GAAP measures should not be considered as a substitute for results that are presented in a manner consistent with GAAP. These non-GAAP measures are provided to enhance investors' overall understanding of our financial performance.

Glossary of Terms

In discussing and analyzing our business, we utilize several metrics and other terms that are defined in the following Glossary of Terms. Italics indicate other defined terms that appear elsewhere in the Glossary.

Asset-based revenues — Revenues consisting of (1) bank deposit account fees, (2) net interest revenue and (3) investment product fees. The primary factors driving our asset-based revenues are average balances and average rates. Average balances consist primarily of average client bank deposit account balances, average client margin balances, average segregated cash balances, average client credit balances, average fee-based investment balances and average securities borrowing and securities lending balances. Average rates consist of the average interest rates and fees earned and paid on such balances.

Average client trades per day — Total trades divided by the number of trading days in the period. This metric is also known as daily average revenue trades ("DARTs").

Average commissions per trade — Total transaction fees and commissions revenue as reported on our consolidated financial statements, less order routing revenue, divided by total trades for the period. Transaction fees and commissions revenue primarily consist of order routing revenue, trading commissions and markups on riskless principal transactions in fixed-income securities.

Basis point — When referring to interest rates, one basis point represents one one-hundredth of one percent.

Bank deposit account fees — Revenues generated from a sweep program that is offered to eligible clients of the Company whereby clients' uninvested cash is swept to FDIC-insured (up to specified limits) money market deposit accounts at affiliated and non-affiliated third-party financial institutions participating in the program.

Beneficiary accounts — Brokerage accounts managed by a custodian, guardian, conservator or trustee on behalf of one or more beneficiaries. Examples include accounts maintained under the Uniform Gift to Minors Act (UGMA) or Uniform Transfer to Minors Act (UTMA), guardianship, conservatorship and trust arrangements and pension or profit plan for small business accounts.

Brokerage accounts — Accounts maintained by us on behalf of clients for securities brokerage activities. The primary types of brokerage accounts are cash accounts, margin accounts, IRA accounts and beneficiary accounts. Futures accounts are sub-accounts associated with a brokerage account for clients who want to trade futures and/or options on futures. Forex accounts are sub-accounts associated with a brokerage account for clients who want to engage in foreign exchange trading.

Cash accounts — Brokerage accounts that do not have margin account approval.

Client assets — The total value of cash and securities in brokerage accounts.

Client cash and money market assets — The sum of all client cash balances, including client credit balances and client cash balances swept into bank deposit accounts or money market mutual funds.

37

Client credit balances — Client cash held in brokerage accounts, excluding balances generated by client short sales on which no interest is paid. Interest paid on client credit balances is a reduction of net interest revenue. Client credit balances are included in "payable to clients" on our consolidated financial statements.

Client margin balances — The total amount of cash loaned to clients in margin accounts. Such loans are secured by client assets. Interest earned on client margin balances is a component of net interest revenue. Client margin balances are included in "receivable from clients, net" on our consolidated financial statements.

Consolidated duration — The weighted average remaining years until maturity of our spread-based assets. For purposes of this calculation, floating rate balances are treated as having a one-month duration. Consolidated duration is used in analyzing our aggregate interest rate sensitivity.

Daily average revenue trades ("DARTs") — Total trades divided by the number of trading days in the period. This metric is also known as average client trades per day.

EBITDA — EBITDA (earnings before interest, taxes, depreciation and amortization) is a non-GAAP financial measure. We consider EBITDA to be an important measure of our financial performance and of our ability to generate cash flows to service debt, fund capital expenditures and fund other corporate investing and financing activities. EBITDA is used as the denominator in the consolidated leverage ratio calculation for covenant purposes under our senior revolving credit facility. EBITDA eliminates the non-cash effect of tangible asset depreciation and amortization and intangible asset amortization. EBITDA should be considered in addition to, rather than as a substitute for, GAAP pre-tax income, net income and cash flows from operating activities.

Fee-based investment balances — Client assets invested in money market mutual funds, other mutual funds and our programs such as AdvisorDirect,^® Essential Portfolios, Selective Portfolios and Personalized Portfolios on which we earn fee revenues. Fee revenues earned on these balances are included in "investment product fees" on our consolidated financial statements.

Forex accounts — Sub-accounts maintained by us on behalf of clients for foreign exchange trading. Each forex account must be associated with a brokerage account. Forex accounts are not counted separately for purposes of our client account metrics.

Funded accounts — All open client accounts with a total liquidation value greater than zero.

Futures accounts — Sub-accounts maintained by us on behalf of clients for trading in futures and/or options on futures. Each futures account must be associated with a brokerage account. Futures accounts are not counted separately for purposes of our client account metrics.

Insured Deposit Account — We are party to an Insured Deposit Account ("IDA") agreement with TD Bank USA, N.A. ("TD Bank USA"), TD Bank, N.A. and The Toronto-Dominion Bank ("TD"). Under the IDA agreement, TD Bank USA and TD Bank, N.A. (together, the "TD Depository Institutions") make available to our clients FDIC-insured (up to specified limits) money market deposit accounts as either designated sweep vehicles or as non-sweep deposit accounts. We provide marketing, recordkeeping and support services for the TD Depository Institutions with respect to the money market deposit accounts. In exchange for providing these services, the TD Depository Institutions pay us an aggregate marketing fee based on the weighted average yield earned on the client IDA assets, less the actual interest paid to clients, a servicing fee to the TD Depository Institutions and the cost of FDIC insurance premiums. Fee revenues earned under this agreement are included in "bank deposit account fees" on our consolidated financial statements.

Interest-earning assets — Consist of client margin balances, segregated cash, deposits paid on securities borrowing and other cash and interest-earning investment balances.

Interest rate-sensitive assets — Consist of spread-based assets and client cash invested in money market mutual funds.

Investment product fees — Revenues earned on fee-based investment balances. Investment product fees consists of fees earned on client assets invested in money market mutual funds, other mutual funds and through investment programs such as AdvisorDirect,^® Essential Portfolios, Selective Portfolios and Personalized Portfolios. Investment product fees also includes fees earned on client assets managed by independent registered investment advisors utilizing our trading and investing platforms.

IRA accounts (Individual Retirement Arrangements) — A personal trust account for the exclusive benefit of a U.S. individual (or his or her beneficiaries) that provides tax advantages in accumulating funds to save for retirement or other qualified purposes. These accounts are subject to numerous restrictions on additions to and withdrawals from the account, as well as prohibitions against certain investments or transactions conducted within the account. We offer traditional, Roth, Savings Incentive Match Plan for Employees (SIMPLE) and Simplified Employee Pension (SEP) IRA accounts.

Liquid assets — Liquid assets is a non-GAAP financial measure that we consider to be an important measure of our liquidity. Liquid assets may be utilized for general corporate purposes and is defined as the sum of (1) corporate cash and cash equivalents, (2) corporate investments, less securities sold under agreements to repurchase, and (3) our regulated subsidiaries' net capital in excess of minimum operational targets established by management. Corporate cash and cash equivalents includes cash and cash equivalents from our investment advisory subsidiaries. Liquid assets represents available capital, including any capital from our

38

regulated subsidiaries in excess of established management operational targets. We include the excess capital of our regulated subsidiaries in the calculation of liquid assets, rather than simply including regulated subsidiaries' cash and cash equivalents, because capital requirements may limit the amount of cash available for dividend from the regulated subsidiaries to the parent company. Net capital in excess of minimum operational targets established by management is generally available for dividend from the regulated subsidiaries to the parent company. Liquid assets is based on more conservative measures of net capital than regulatory requirements because we generally manage to higher levels of net capital at our regulated subsidiaries than the regulatory thresholds require. Liquid assets should be considered as a supplemental measure of liquidity, rather than as a substitute for GAAP cash and cash equivalents.

Liquidation value — The net value of a client's account holdings as of the close of a regular trading session. Liquidation value includes client cash and the value of long security positions, less margin balances and the cost to buy back short security positions. It also includes the value of open futures, foreign exchange and options positions.

Margin accounts — Brokerage accounts in which clients may borrow from us to buy securities or for any other purpose, subject to regulatory and Company-imposed limitations.

Net interest margin ("NIM") — A measure of the net yield on our average spread-based assets. Net interest margin is calculated for a given period by dividing the annualized sum of bank deposit account fees and net interest revenue by average spread-based assets.

Net interest revenue — Net interest revenue is interest revenues less brokerage interest expense. Interest revenues are generated by charges to clients on margin balances maintained in margin accounts, the investment of cash from operations and segregated cash and interest earned on securities borrowing/securities lending. Brokerage interest expense consists of amounts paid or payable to clients based on credit balances maintained in brokerage accounts and interest incurred on securities borrowing/securities lending. Brokerage interest expense does not include interest on our non-brokerage borrowings.

Net new assets — Consists of total client asset inflows, less total client asset outflows, excluding activity from business combinations. Client asset inflows include interest and dividend payments and exclude changes in client assets due to market fluctuations. Net new assets are measured based on the market value of the assets as of the date of the inflows and outflows.

Net new asset growth rate (annualized) — Annualized net new assets as a percentage of client assets as of the beginning of the period.

Non-GAAP Net Income and Non-GAAP Diluted EPS — Non-GAAP net income and non-GAAP diluted earnings per share ("EPS") are non-GAAP financial measures. We define non-GAAP net income as net income adjusted to remove the after-tax effect of (1) amortization of acquired intangible assets and (2) acquisition-related expenses associated with the Company's business acquisitions. We consider non-GAAP net income and non-GAAP diluted EPS as important measures of our financial performance because they exclude certain items that may not be indicative of our core operating results and business outlook and may be useful in evaluating the operating performance of the business and facilitating a meaningful comparison of our results in the current period to those in prior and future periods. Amortization of acquired intangible assets is excluded because management does not believe it is indicative of our underlying business performance. Acquisition-related expenses are excluded as these costs are not representative of the costs of running our on-going business. Non-GAAP net income and non-GAAP diluted EPS should be considered in addition to, rather than as a substitute for, GAAP net income and GAAP diluted EPS.

Order routing revenue — Revenues generated from payments and/or rebates received from market centers. Order routing revenue is a component of transaction-based revenues.

Securities borrowing — We borrow securities temporarily from other broker-dealers in connection with our broker-dealer business. We deposit cash as collateral for the securities borrowed, and generally earn interest revenue on the cash deposited with the counterparty. We also incur interest expense for borrowing certain securities.

Securities lending — We loan securities temporarily to other broker-dealers in connection with our broker-dealer business. We receive cash as collateral for the securities loaned, and generally incur interest expense on the cash deposited with us. We also earn revenue for lending certain securities.

Securities sold under agreements to repurchase (repurchase agreements) — We sell securities to counterparties with an agreement to repurchase the same or substantially the same securities at a stated price plus interest on a specified date. We utilize repurchase agreements to finance our short-term liquidity and capital needs. Under these financing transactions, we receive cash from counterparties and provide U.S. Treasury securities as collateral.

Segregated cash — Client cash and investments segregated in compliance with Rule 15c3-3 of the Securities Exchange Act of 1934 (the Customer Protection Rule) and other regulations. Interest earned on segregated cash is a component of net interest revenue.

39

Spread-based assets — Client and brokerage-related asset balances, consisting of bank deposit account balances and interest-earning assets. Spread-based assets is used in the calculation of our net interest margin and our consolidated duration.

Total trades — Revenue-generating client securities trades, which are executed by our broker-dealer and FCM/FDM subsidiaries. Trades generate revenue from order routing, commissions, markups on riskless principal transactions in fixed income securities and transaction fees.

Trading days — Days in which the U.S. equity markets are open for a full trading session. Reduced exchange trading sessions are treated as half trading days.

Transaction fees and commissions — Revenues earned on order routing, trading commissions and markups on riskless principal transactions in fixed-income securities. Revenues earned on trading commissions includes client trades in options (contract fees), futures, foreign exchange, mutual funds, fixed income securities, exchange-traded notes and closed-end funds. In addition, trading commissions are earned on client trades in common and preferred stock, exchange traded funds ("ETFs") and options which are processed through a broker or the interactive voice response phone system.

Transaction-based revenues — Revenues generated from client trade execution, consisting primarily of order routing revenue, commissions, markups on riskless principal transactions in fixed income securities and transaction clearing fees.

Results of Operations

Changes in average client balances, especially bank deposit account, margin, credit and fee-based investment balances, may significantly impact our results of operations. Changes in interest rates also significantly impact our results of operations. We seek to mitigate interest rate risk by aligning the average duration of our interest-earning assets with that of our interest-bearing liabilities. We cannot predict the direction of interest rates or the levels of client balances. If interest rates rise, we generally expect to earn a larger net interest spread. Conversely, a falling interest rate environment generally would result in us earning a smaller net interest spread.

Conditions in the U.S. equity markets significantly impact the volume of our clients' trading activity. There is a relationship between the volume of our clients' trading activity and our results of operations. We cannot predict future trading volumes in the U.S. equity markets. If client trading activity increases, we generally expect that it would have a positive impact on our results of operations. If client trading activity declines, we generally expect that it would have a negative impact on our results of operations.

Effective October 3, 2019, we reduced our online exchange-listed stock, exchange-traded funds ("ETF") (domestic and Canadian) and option trade commissions from $6.95 to $0 per trade (plus $0.65 per contract and no exercise or assignment fees on option trades).

Financial Performance Metrics

Net income, diluted earnings per share and EBITDA are key metrics we use in evaluating our financial performance. Net income and diluted earnings per share are GAAP financial measures and EBITDA is a non-GAAP financial measure.

We consider EBITDA to be an important measure of our financial performance and of our ability to generate cash flows to service debt, fund capital expenditures and fund other corporate investing and financing activities. EBITDA is used as the denominator in the consolidated leverage ratio calculation for covenant purposes under the TD Ameritrade Holding Corporation senior revolving credit facility. EBITDA eliminates the non-cash effect of tangible asset depreciation and amortization and intangible asset amortization. EBITDA should be considered in addition to, rather than as a substitute for, GAAP pre-tax income, net income and cash flows from operating activities.

Three Months Ended March 31, 2020 Compared to Three Months Ended March 31, 2019

Our net income decreased 11% for the second quarter of fiscal year 2020 compared to the same period in the prior fiscal year, primarily due to an increase in operating expenses, partially offset by an increase in net revenues, lower income taxes and a decrease in interest on borrowings. Detailed analysis of net revenues and expenses is presented later in this discussion.

Our EBITDA decreased 9% for the second quarter of fiscal year 2020 compared to the same period in the prior fiscal year, primarily due to an increase in operating expenses excluding depreciation and amortization, partially offset by an increase in net revenues.

Our diluted earnings per share decreased 8% to $0.82 for the second quarter of fiscal year 2020 compared to $0.89 for the second quarter of the prior fiscal year due to lower net income, partially offset by a 3% decrease in the weighted average diluted shares outstanding as a result of our stock repurchase programs.

Six Months Ended March 31, 2020 Compared to Six Months Ended March 31, 2019

Our net income decreased 25% for the first half of fiscal year 2020 compared to the same period in the prior fiscal year, primarily due to a decrease in net revenues, an increase in operating expenses and the effect of a $14 million favorable legal settlement during the first half of the prior fiscal year. The decreasing impact of these items on net income was partially offset by lower income taxes and a decrease in interest on borrowings.

Our EBITDA decreased 21% for the first half of fiscal year 2020 compared to the same period in the prior fiscal year, primarily due to a decrease in net revenues, an increase in operating expenses excluding depreciation and amortization and the effect of a $14 million favorable legal settlement during the first half of the prior fiscal year.

Our diluted earnings per share decreased 22% to $1.52 for the first half of fiscal year 2020 compared to $1.96 for the first half of the prior fiscal year due to lower net income, partially offset by a 4% decrease in the weighted average diluted shares outstanding as a result of our stock repurchase programs.

Operating Metrics

Our largest sources of revenues are asset-based revenues and transaction-based revenues. For the first half of fiscal year 2020, asset-based revenues and transaction-based revenues accounted for 68% and 28% of our net revenues, respectively. Asset-based revenues consist of (1) bank deposit account fees, (2) net interest revenue and (3) investment product fees. The primary factors driving our asset-based revenues are average balances and average rates. Average balances consist primarily of average client bank deposit account balances, average client margin balances, average segregated cash balances, average client credit balances, average fee-based investment balances and average securities borrowing and lending balances. Average rates consist of the average interest rates and fees earned and paid on such balances. The primary factors driving our transaction-based revenues are total trades and average commissions per trade. We also consider client account and client asset metrics, although we believe they are generally of less significance to our results of operations for any particular period than our metrics for asset-based and transaction-based revenues.

Asset-Based Revenue Metrics

We calculate the return on our bank deposit account balances and our interest-earning assets using a measure we refer to as net interest margin. Net interest margin is calculated for a given period by dividing the annualized sum of bank deposit account fees and net interest revenue by average spread-based assets. Spread-based assets consist of average bank deposit account balances and average interest-earning assets, which include client margin balances, segregated cash, deposits paid on securities borrowing and other cash and interest-earning investment balances. The following table sets forth net interest margin and average spread-based assets (dollars in millions):

Three-Month Periods Ended March 31, 2020 and 2019

Net Revenues

We currently project fiscal year 2020 net revenues to be above the midpoint of the $4.9 billion and $5.3 billion range. In this scenario, we anticipate the following for the next two quarters of fiscal year 2020: average client trades per day of 1.7 million; average commissions of $2.25 to $2.30 per trade with derivative trades at 33% of average client trades per day; average annualized yield of 1.00% on bank deposit account balances ranging between $146 billion and $150 billion; and average annualized yields of approximately 2.65% and 0.30% on client margin balances and fee-based investment balances, respectively. This scenario also assumes the forward interest rate curve as of late March 2020.

Asset-based revenues, which consists of bank deposit account fees, net interest revenue and investment product fees, decreased 1% to $920 million, primarily due to a decrease of 29 basis points in net interest margin to 1.88%, partially offset by a 12% increase in average spread-based balances, an $18 million increase in net interest revenue from our securities borrowing/lending program and an increase of 12 basis points in the average yield earned on fee-based investment balances. The decrease in net interest margin was primarily due to the Federal Open Market Committee decreasing the target range for the federal funds rate by 50 basis points (to between 1.75% to 2.00%) during the fourth quarter of fiscal year 2019 and by 175 basis points during the first half of fiscal year 2020 (to between 0% to 0.25%). The growth in average spread-based balances is primarily due to our success in attracting net new client assets.

Bank deposit account fees increased 3% to $444 million, primarily due to lower interest rates paid to clients resulting from recent decreases in the federal funds rate, as described above, and a 10% increase in average client bank deposit account balances. These increases were partially offset by the impact of recent decreases in the federal funds rate on the floating-rate investment balances within the bank deposit account portfolio.

Net interest revenue decreased 8% to $332 million, primarily due to a decrease of 110 basis points in the average yield earned on interest-earning assets as a result of recent decreases in the federal funds rate, as described above. This decrease was partially offset by increases in average segregated cash, client margin and other cash and interest-earning investment balances and an $18 million increase in net interest revenue from our securities borrowing/lending program.

Investment product fees increased 5% to $144 million, primarily due to increased balances in certain high yielding investment products, partially offset by a net decrease in average fee-based investment balances. The average yield earned on fee-based investment balances increased by 12 basis points, as average balance increases were primarily in investment products which earn higher yields. Average fee-based investment balances decreased overall as a result of (1) the exclusion of equity and ETF assets from the Institutional Asset Based Pricing program and the discontinuation of the ETF Market Center program subsequent to the reduction of our online exchange-listed stock and ETF commissions to $0 per trade, as described below, and (2) the sale of TD Ameritrade Trust Company's ("TDATC"), an indirect wholly-owned subsidiary of the Parent, retirement plan custody and trust assets during the third quarter of the prior fiscal year.

Transaction fees and commissions decreased 1% to $481 million, primarily due to lower average commissions per trade, partially offset by an increase in client trading activity and the effect of one more trading day during the second quarter of fiscal year 2020 compared to the second quarter of the prior fiscal year. Average commissions per trade decreased to $2.00 from $7.01, primarily due to the reduction of our online exchange-listed stock, ETFs (domestic and Canadian) and option trade commissions from $6.95 to $0 per trade (plus $0.65 per contract and no exercise or assignment fees on option trades) effective October 3, 2019. Average client trades per day increased 144% to 2,101,804 for the second quarter of fiscal year 2020 compared to 860,359 for the second quarter of the prior fiscal year. Order routing revenue increased 85% to $220 million due to higher trading volumes.

Other revenues increased 126% to $79 million, primarily due to favorable fair market value adjustments to U.S. government debt securities held by our broker-dealer subsidiaries, other fee revenue associated with additional accounts and transaction processing volumes, and increased fees from proxy services.

Operating Expenses

We anticipate total operating expenses to range from $3.0 billion to $3.1 billion for fiscal year 2020, which is slightly up from prior guidance due to costs related to the proposed Merger, certain employee compensation expenses and higher client engagement.

Employee compensation and benefits increased 11% to $377 million, primarily due to higher incentive-based compensation related to Company and individual performance, including our continued success in attracting net new client assets, a $9 million special stipend award to address the residual impacts of working from home during the pandemic, annual merit increases and $5 million related to organizational changes. These increases were partially offset by a decrease in the average headcount. The average number of full-time equivalent employees decreased to 9,068 for the second quarter of fiscal year 2020 compared to 9,515 for the second quarter of the prior fiscal year.

Clearing and execution costs increased 42% to $75 million, primarily due to higher client trading volumes.

45

Depreciation and amortization increased 19% to $43 million, primarily due to recent software and technology infrastructure upgrades.

Professional services decreased 7% to $69 million, primarily due to decreased usage of consulting and contract services, partially offset by $8 million of costs related to the proposed Merger during the second quarter of fiscal year 2020.

Advertising expense increased 18% to $87 million. We generally adjust our level of advertising spending in relation to stock market activity and other market conditions in an effort to maximize the number of new accounts while minimizing the advertising cost per new account.

Other operating expenses increased 86% to $65 million, primarily due to operational and credit losses as a result of market volatility, partially offset by lower costs related to travel and off-site meetings due to the COVID-19 pandemic.

Other Expense (Income) and Income Taxes

Interest on borrowings decreased 16% to $31 million, primarily due to a decrease of 101 basis points in the average effective interest rate on our debt, partially offset by a 7% increase in average debt outstanding. We issued $500 million of 2.75% Senior Notes due on October 1, 2029 on August 13, 2019 and we utilized repurchase agreements during the second quarter of fiscal year 2020. For more information regarding our debt, see "Long-term Debt and Other Borrowings" later in this section.

Our effective income tax rate was 25.5% for the second quarter of fiscal year 2020, compared to 25.3% for the second quarter of the prior fiscal year. We estimate our effective income tax rate to be approximately 26% for the remainder of fiscal year 2020, excluding the effect of any adjustments related to remeasurement or resolution of uncertain tax positions and federal incentives. However, we expect to experience some volatility in our quarterly and annual effective income tax rate because current accounting rules for uncertain tax positions require that any change in measurement of a tax position taken in a prior tax year be recognized as a discrete event in the period in which the change occurs. We also anticipate the potential for increased volatility in our future quarterly effective income tax rate from the accounting for income taxes related to equity-based compensation, which requires the income tax effects of exercised or vested stock-based awards to be treated as discrete items in the period in which they occur.

Six-Month Periods Ended March 31, 2020 and 2019

Net Revenues

Asset-based revenues slightly increased to $1.88 billion for the first half of fiscal year 2020, primarily due to a 9% increase in average spread-based balances, a $40 million increase in net interest revenue from our securities borrowing/lending program and an increase of 11 basis points in the average yield earned on fee-based investment balances. These increases were mostly offset by a decrease of 19 basis points in net interest margin to 1.99%. The growth in average spread-based balances is primarily due to our success in attracting net new client assets. The decrease in net interest margin was primarily due to the Federal Open Market Committee decreasing the target range for the federal funds rate by 50 basis points (to between 1.75% to 2.00%) during the fourth quarter of fiscal year 2019 and by 175 basis points during the first half of fiscal year 2020 (to between 0% to 0.25%).

Bank deposit account fees increased 5% to $899 million, primarily due to lower interest rates paid to clients resulting from recent decreases in the federal funds rate, as described above, and an increase in average client bank deposit account balances. These increases were partially offset by the impact of recent decreases in the federal funds rate on the floating-rate investment balances within the bank deposit account portfolio.

Net interest revenue decreased 6% to $690 million, primarily due to a decrease of 104 basis points in the average yield earned on interest-earning assets as a result of recent decreases in the federal funds rate, as described above, and a 2% decrease in average client margin balances. These decreases were partially offset by increases in average segregated cash and other cash and interest-earning investment balances and a $40 million increase in net interest revenue from our securities borrowing/lending program.

Investment product fees increased 4% to $290 million, primarily due to increased balances in certain high yielding investment products, partially offset by a net decrease in average fee-based investment balances. Average fee-based investment balances decreased overall as a result of (1) the exclusion of equity and ETF assets from the Institutional Asset Based Pricing program and the discontinuation of the ETF Market Center program subsequent to the reduction of our online exchange-listed stock and ETF commissions to $0 per trade, as described below, and (2) the sale of TDATC retirement plan custody and trust assets during the third quarter of the prior fiscal year. The average yield earned on fee-based investment balances increased by 11 basis points, as average balance increases were primarily in investment products which earn higher yields.

Transaction fees and commissions decreased 23% to $785 million, primarily due to lower average commissions per trade, partially offset by an increase in client trading activity and the effect of two more trading days during the first half of fiscal year 2020 compared to the first half of the prior fiscal year. Average commissions per trade decreased to $2.21 from $7.05, primarily due to the reduction of our online exchange-listed stock, ETFs (domestic and Canadian) and option trade commissions from $6.95 to $0 per trade (plus $0.65 per contract and no exercise or assignment fees on option trades) effective October 3, 2019. Average client

46

trades per day increased 75% to 1,560,727 for the first half of fiscal year 2020 compared to 894,378 for the first half of the prior fiscal year. Order routing revenue increased 43% to $355 million due to higher trading volumes.

Other revenues increased 59% to $108 million, primarily due to favorable fair market value adjustments to U.S. government debt securities held by our broker-dealer subsidiaries, other fee revenue associated with additional accounts and transaction processing volumes, and increased fees from proxy services.

Operating Expenses

Employee compensation and benefits increased 8% to $707 million, primarily due to higher incentive-based compensation related to Company and individual performance, including our continued success in attracting net new client assets, $12 million related to organizational changes, a $9 million special stipend award to address the residual impacts of working from home during the pandemic and annual merit increases. These increases were partially offset by a decrease in the average headcount. The average number of full-time equivalent employees decreased to 9,108 for the first half of fiscal year 2020 compared to 9,410 for the first half of the prior fiscal year.

Clearing and execution costs increased 23% to $125 million, primarily due to higher client trading volumes.

Depreciation and amortization increased 18% to $84 million, primarily due to recent software and technology infrastructure upgrades.

Professional services increased 14% to $167 million, primarily due to $34 million of costs related to the proposed Merger, partially offset by decreased usage of consulting and contract services and lower costs associated with legal matters.

Other operating expenses increased 26% to $102 million, primarily due to operational and credit losses as a result of market volatility.

Other Expense (Income) and Income Taxes

Interest on borrowings decreased 10% to $63 million, primarily due to a decrease of 73 basis points in the average effective interest rate on our debt, partially offset by an 8% increase in average debt outstanding. On October 30, 2018, we issued $600 million of variable-rate Senior Notes due November 1, 2021 and $400 million of 3.75% Senior Notes due April 1, 2024. We also issued $500 million of 2.75% Senior Notes due on October 1, 2029 on August 13, 2019 and we utilized repurchase agreements during the second quarter of fiscal year 2020.

Other non-operating income for the first half of the prior fiscal year consists of a $14 million favorable legal settlement.

Our effective income tax rate was 24.4% for the first half of fiscal year 2020, compared to 23.7% for the first half of the prior fiscal year. The effective income tax rate for the first half of fiscal year 2020 included $7 million of net favorable adjustments related to state income tax matters. This item had a favorable impact on the Company's earnings for the first half of fiscal year 2020 of approximately $0.01 per share. The effective income tax rate for the first half of the prior fiscal year included $18 million of favorable adjustments related to state income tax matters and a $3 million income tax benefit resulting from the vesting of equity-based compensation. These items had a favorable impact on our earnings for the first half of the prior fiscal year of approximately $0.04 per share.

Liquidity and Capital Resources

We have established liquidity and capital policies to support the successful execution of business strategies to meet operational needs and to satisfy applicable regulatory requirements under both normal and modeled stressed conditions. Our liquidity management policies are designed to mitigate the potential risk that we may be unable to meet current and future cash flow needs. Management of our liquidity is accomplished by (1) daily monitoring of our cash flow needs at TD Ameritrade Holding Corporation (the "Parent") and its operating subsidiaries, and (2) performing periodic liquidity stress testing related to market and company-specific liquidity stress events in order to identify and plan for liquidity risk exposures.

We have historically financed our liquidity and capital needs primarily through the use of funds generated from subsidiary operations and from short-term borrowings. We have also issued common stock and long-term debt to finance mergers and acquisitions and for other corporate purposes. Our liquidity needs during the first half of fiscal year 2020 were financed primarily from our subsidiaries' earnings, cash on hand and borrowings. We plan to finance both our ordinary capital and liquidity needs during the remainder of fiscal year 2020 primarily from our subsidiaries' earnings, cash on hand and borrowings, as we do not expect the COVID-19 pandemic to have an adverse impact to our results of operations and cash flows in the near term.

Parent Company

The Parent conducts substantially all of its business through its operating subsidiaries, principally its broker-dealer and futures commission merchant ("FCM")/forex dealer member ("FDM") subsidiaries. Dividends from our subsidiaries are an important source of liquidity for the Parent. Some of our subsidiaries are subject to requirements of the Securities and Exchange Commission

47

("SEC"), the Financial Industry Regulatory Authority, the Commodity Futures Trading Commission ("CFTC"), the National Futures Association and other regulators relating to liquidity, capital standards and the use of client funds and securities, which may limit funds available for the payment of dividends to the Parent.

Prior to the proposed Merger, we had planned to return at least 90% of our non-GAAP net income to our stockholders through cash dividends and stock repurchases, pay a quarterly cash dividend of at least $0.31 per share and repurchase a minimum of 15 million shares of our common stock during fiscal year 2020. In accordance with the Merger Agreement, we plan to continue to pay a quarterly cash dividend not to exceed $0.31 per share and cease repurchases of our common stock for the remainder of fiscal year 2020. For more information about our stock repurchases and cash dividends, see "Stock Repurchase Programs" and "Cash Dividends" later in this section.

The Parent may make loans of cash or securities under committed and/or uncommitted lines of credit with each of its primary broker-dealer and FCM/FDM subsidiaries in order to provide liquidity. Liquidity could be used to fund increases in our subsidiaries' deposit requirements with clearinghouses, and to provide operating liquidity for client trading and investing activity in the normal course of business and during times of market volatility. Committed facilities of $1.55 billion and uncommitted facilities of $600 million under the Parent's intercompany credit agreements are available to its primary broker-dealer and FCM/FDM subsidiaries. For more information about these credit agreements, see "Long-term Debt and Other Borrowings — Intercompany Credit Agreements" later in this section.

Broker-dealer and Futures Commission Merchant/Forex Dealer Member Subsidiaries

Our broker-dealer and FCM/FDM subsidiaries are subject to regulatory requirements that are intended to ensure their liquidity and general financial soundness. Under the SEC's Uniform Net Capital Rule (Rule 15c3-1 under the Securities Exchange Act of 1934, or the "Exchange Act"), our broker-dealer subsidiaries are required to maintain, at all times, at least the minimum level of net capital required under SEC Rule 15c3-1. For our clearing broker-dealer subsidiary, the minimum net capital level is determined by a calculation described in SEC Rule 15c3-1 that is primarily based on the broker-dealer's "aggregate debits," which primarily consist of client margin balances at the clearing broker-dealer. Since our aggregate debits may fluctuate significantly, our minimum net capital requirements may also fluctuate significantly from period to period. The Parent may make cash capital contributions to our broker-dealer and FCM/FDM subsidiaries, if necessary, to meet minimum net capital requirements.

Each of our broker-dealer subsidiaries may not repay any subordinated borrowings, pay cash dividends or make any unsecured advances or loans to its parent company or employees if such payment would result in a net capital amount of less than (1) 5% of aggregate debit balances or (2) 120% of its minimum dollar requirement. TD Ameritrade Futures & Forex LLC ("TDAFF"), our FCM and FDM subsidiary, must provide notice to the CFTC if its adjusted net capital amounts to less than (1) 110% of its risk-based capital requirement under CFTC Regulation 1.17, (2) 150% of its $1.0 million minimum dollar requirement, or (3) 110% of $20.0 million plus 5% of all liabilities owed to forex clients in excess of $10.0 million. These broker-dealer, FCM and FDM net capital thresholds, which are specified in Rule 17a-11 under the Exchange Act and CFTC Regulations 1.12 and 5.6, are typically referred to as "early warning" net capital thresholds.

The following tables summarize our broker-dealer and FCM/FDM subsidiaries' net capital and adjusted net capital, respectively, as of March 31, 2020 (dollars in millions):

	Net Capital		Early Warning Threshold		Net Capital in Excess of Early Warning Threshold
TD Ameritrade Clearing, Inc.	$	3,265	$	1,007	$	2,258
TD Ameritrade, Inc.	$	331	$	0.3	$	331

	Adjusted Net Capital		Early Warning Threshold		Adjusted Net Capital in Excess of Early Warning Threshold
TD Ameritrade Futures & Forex LLC	$	153	$	25	$	128

Our clearing broker-dealer subsidiary, TD Ameritrade Clearing, Inc. ("TDAC"), engages in activities such as settling client securities transactions with clearinghouses, extending credit to clients through margin lending, securities lending and borrowing transactions and processing client cash sweep transactions to and from bank deposit accounts and money market mutual funds. These types of broker-dealer activities require active daily liquidity management.

Most of TDAC's assets are readily convertible to cash, consisting primarily of cash and investments segregated for the exclusive benefit of clients, receivables from clients and receivables from brokers, dealers and clearing organizations. Cash and investments segregated for the exclusive benefit of clients may be held in cash, reverse repurchase agreements (collateralized by U.S. government

48

debt securities), U.S. Treasury securities, U.S. government agency mortgage-backed securities and other qualified securities. Receivables from clients consist of margin loans, which are demand loan obligations secured by readily marketable securities. Receivables from brokers, dealers and clearing organizations primarily arise from current open transactions, which usually settle or can be settled within a few business days.

TDAC is subject to cash deposit and collateral requirements with the Depository Trust & Clearing Corporation ("DTCC") and the Options Clearing Corporation ("OCC"), which may fluctuate significantly from time to time based on the nature and size of our clients' trading activity.

The following table sets forth TDAC's cash and investments deposited with clearing organizations for the clearing of client equity and option trades (dollars in millions):

	March 31, 2020		September 30, 2019
TD Ameritrade Clearing, Inc.	$	1,330	$	703

Liquidity needs for TDAC relating to client trading and margin borrowing are met primarily through cash balances in client brokerage accounts and through lending and pledging of client margin securities. Cash balances in client brokerage accounts not used for client trading and margin borrowing activity are not generally available for other liquidity purposes and must be segregated for the exclusive benefit of clients under Rule 15c3-3 of the Exchange Act.

Cash balances in client brokerage accounts are summarized in the following table (dollars in billions):

	March 31, 2020		September 30, 2019
TD Ameritrade Clearing, Inc.	$	33.0	$	26.8

Cash and investments segregated in special reserve bank accounts for the exclusive benefit of clients under SEC Rule 15c3-3 are summarized in the following table (dollars in billions):

	March 31, 2020		September 30, 2019
TD Ameritrade Clearing, Inc.	$	19.2	$	8.4

For general liquidity needs, TDAC currently maintains two senior unsecured committed revolving credit facilities with an aggregate principal amount of $1.45 billion. TDAC also utilizes secured uncommitted lines of credit for short-term liquidity needs. These facilities are described under "Long-term Debt and Other Borrowings" later in this section.

In addition, we have established intercompany credit agreements under which the broker-dealer and FCM/FDM subsidiaries may borrow from the Parent. The Parent's intercompany credit agreements with TDAC provide for a committed revolving loan facility of $1.50 billion and an uncommitted revolving loan facility of $300 million. The intercompany credit agreements are described under "Long-Term Debt and Other Borrowings – Intercompany Credit Agreements" later in this section.

Liquid Assets

Liquid assets is a non-GAAP financial measure that we consider to be an important measure of our liquidity. We include the excess capital of our regulated subsidiaries in the calculation of liquid assets, rather than simply including the regulated subsidiaries' cash and cash equivalents, because capital requirements may limit the amount of cash available for dividend from the regulated subsidiaries to the parent company. Excess capital, as defined below, is generally available for dividend from the regulated subsidiaries to the parent company. Liquid assets should be considered as a supplemental measure of liquidity, rather than as a substitute for GAAP cash and cash equivalents.

Liquid assets may be utilized for general corporate purposes and is defined as the sum of (1) corporate cash and cash equivalents, (2) corporate investments, less securities sold under agreements to repurchase, and (3) our regulated subsidiaries' net capital in excess of minimum operational targets established by management. Corporate cash and cash equivalents includes cash and cash equivalents from our investment advisory subsidiaries. Liquid assets is based on more conservative measures of net capital than regulatory requirements because we generally manage to higher levels of net capital at our regulated subsidiaries than the regulatory thresholds require.

49

The following table sets forth a reconciliation of cash and cash equivalents, which is the most directly comparable GAAP measure, to liquid assets (dollars in millions): 

	Mar. 31,			Sept. 30,
	2020			2019			Change
Cash and cash equivalents (GAAP)	$	3,729		$	2,852		$	877
Less:   Non-corporate cash and cash equivalents	(2,019		)	(2,478		)	459
Corporate cash and cash equivalents	1,710			374			1,336
Corporate investments	574			1,668			(1,094		)
Excess regulatory net capital over management targets	1,432			859			573
Liquid assets (non-GAAP)	$	3,716		$	2,901		$	815

The changes in liquid assets are summarized as follows (dollars in millions): 

Liquid assets as of September 30, 2019	$	2,901
Plus: EBITDA(1)	1,297
Other changes in working capital and regulatory net capital	232
Net change in cash collateral received from interest rate swap counterparties	136

Long-term Debt and Other Borrowings

The following is a summary of our long-term debt and other borrowings. For additional details, see Note 7 – Long-term Debt and Other Borrowings under Item 1, Financial Statements – Notes to Condensed Consolidated Financial Statements.

Senior Notes — As of March 31, 2020, we had $3.55 billion aggregate principal amount of unsecured Senior Notes (together, the "Senior Notes"). Key information about the Senior Notes outstanding is summarized in the following table (dollars in millions):

Description	Date Issued	Maturity Date	Aggregate Principal	Interest Rate
2021 Notes	October 30, 2018	November 1, 2021	$600	Variable
2022 Notes	March 4, 2015	April 1, 2022	$750	2.950%
2024 Notes	October 30, 2018	April 1, 2024	$400	3.750%
2025 Notes	October 17, 2014	April 1, 2025	$500	3.625%
2027 Notes	April 27, 2017	April 1, 2027	$800	3.300%
2029 Notes	August 13, 2019	October 1, 2029	$500	2.750%

Fair Value Hedging — We are exposed to changes in the fair value of our fixed-rate Senior Notes resulting from interest rate fluctuations. To hedge a vast majority of this exposure, we entered into fixed-for-variable interest rate swaps on each of the 2022 Notes, 2025 Notes, 2027 Notes and 2029 Notes ( together, the "Hedged Senior Notes"). Each fixed-for-variable interest rate swap has a notional amount and a maturity date matching the aggregate principal amount and maturity date, respectively, for each of the respective Hedged Senior Notes.

The interest rate swaps effectively change the fixed-rate interest on the Hedged Senior Notes to variable-rate interest. Under the terms of the interest rate swap agreements, we receive semi-annual fixed-rate interest payments based on the same rates applicable to the Hedged Senior Notes, and make quarterly variable-rate interest payments based on three-month LIBOR plus (1) 0.9486%

50

for the swap on the 2022 Notes, (2) 1.1022% for the swap on the 2025 Notes, (3) 1.0340% for the swap on the 2027 Notes and (4) 1.2000% for the swap on the 2029 Notes. As of March 31, 2020, the weighted average effective interest rate on the aggregate principal balance of the Senior Notes was 2.92%.

Lines of Credit — TDAC utilizes secured uncommitted lines of credit for short-term liquidity. Under these secured uncommitted lines, TDAC borrows on either a demand or short-term basis from two unaffiliated banks and pledges client margin securities as collateral. Advances under the secured uncommitted lines are dependent on TDAC having acceptable collateral as determined by each secured uncommitted credit agreement. At March 31, 2020, the terms of the secured uncommitted credit agreements do not specify borrowing limits. The availability of TDAC's secured uncommitted lines is subject to approval by the individual banks each time an advance is requested and may be denied. There were no borrowings outstanding under the secured uncommitted lines of credit as of March 31, 2020.

Securities Sold Under Agreements to Repurchase (repurchase agreements) — Under repurchase agreements, we receive cash from the counterparty and provide U.S. government debt securities as collateral. Our repurchase agreements generally mature between seven and 90 days following the transaction date and are accounted for as secured borrowings. As of March 31, 2020, the weighted average interest rate on the $1.22 billion outstanding repurchase agreement balances was 0.19%.

TD Ameritrade Holding Corporation Senior Revolving Credit Facility — The Parent has access to a senior unsecured committed revolving credit facility in the aggregate principal amount of $300 million (the "Parent Revolving Facility"). The maturity date of the Parent Revolving Facility is April 21, 2022. There were no borrowings outstanding under the Parent Revolving Facility as of March 31, 2020.

TD Ameritrade Clearing, Inc. Senior Revolving Credit Facilities — As of March 31, 2020, TDAC has access to two senior unsecured committed revolving credit facilities with an aggregate principal amount of $1.45 billion, consisting of a $600 million (the "$600 Million Revolving Facility") and an $850 million (the "$850 Million Revolving Facility") senior revolving facility. The maturity dates of the $600 Million Revolving Facility and the $850 Million Revolving Facility are April 21, 2022 and May 14, 2020, respectively. There were no borrowings outstanding under the TDAC senior revolving facilities as of March 31, 2020. On April 21, 2020, TDAC entered into an amendment to the $850 Million Revolving Facility, which provides for a senior unsecured revolving credit facility in the aggregate principal amount of $850 million that matures on April 20, 2021 (the "Amended Credit Agreement"). See Note 16 – Subsequent Event under Item 1, Financial Statements – Notes to Condensed Consolidated Financial Statements for additional details regarding the Amended Credit Agreement.

Intercompany Credit Agreements — The Parent has entered into credit agreements with each of its primary broker-dealer and FCM/FDM subsidiaries, under which the Parent may make loans of cash or securities under committed and/or uncommitted lines of credit. Key information about the committed and/or uncommitted lines of credit is summarized in the following table (dollars in millions):

Borrower Subsidiary	Committed Facility	Uncommitted Facility(1)	Termination Date
TD Ameritrade Clearing, Inc.	$1,500	$300	March 1, 2022
TD Ameritrade, Inc.	N/A	$300	March 1, 2022
TD Ameritrade Futures & Forex LLC	$45	N/A	August 11, 2021

(1) The Parent is permitted, but under no obligation, to make loans under uncommitted facilities.

There were no borrowings outstanding under the intercompany credit agreements as of March 31, 2020.

Stock Repurchase Programs

On November 20, 2015, our board of directors authorized the repurchase of up to 30 million shares of our common stock. During the first quarter of fiscal year 2020, we completed the November 20, 2015 stock repurchase authorization by repurchasing the remaining 1.5 million shares at a weighted average purchase price of $35.23 per share. From the inception of this stock repurchase authorization through its completion in October 2019, we have repurchased a total of 30 million shares at a weighted average purchase price of $47.58 per share.

On September 11, 2019, our board of directors authorized the repurchase of up to an additional 30 million shares of our common stock. During the first quarter of fiscal year 2020, we repurchased approximately 2.2 million shares at a weighted average purchase price of $40.26 per share. As of March 31, 2020, we had approximately 27.8 million shares remaining on the stock repurchase authorization. In accordance with the Merger Agreement, we have suspended repurchases under our current stock repurchase authorization.

51

Cash Dividends

We declared a $0.31 per share cash dividend on our common stock during each of the first three quarters of fiscal year 2020. We paid $335 million in cash dividends during the first half of fiscal year 2020. We will pay the third quarter dividend on May 20, 2020 to all holders of record of our common stock as of May 6, 2020.

Contractual Obligations

There have been no material changes in our contractual obligations outside the ordinary course of business since September 30, 2019.

Off-Balance Sheet Arrangements

We enter into guarantees and other off-balance sheet arrangements in the ordinary course of business, primarily to meet the needs of our clients and to manage our asset-based revenues. For information on these arrangements, see the following sections under Item 1, Financial Statements – Notes to Condensed Consolidated Financial Statements: "General Contingencies" and "Guarantees" in Note 9 – Commitments and Contingencies and "Insured Deposit Account Agreement" in Note 15 – Related Party Transactions. Bank deposit account fees, generated from the IDA agreement and other sweep arrangements with non-affiliated third-party depository financial institutions, account for a significant percentage of our net revenues (32% of our net revenues for the first half of fiscal year 2020). These sweep arrangements enable our clients to invest in FDIC-insured (up to specified limits) deposit products without the need for the Company to establish the significant levels of capital that would be required to maintain our own bank charter.

Item 3. – Quantitative and Qualitative Disclosures About Market Risk

Market risk generally represents the risk of loss that may result from the potential change in the value of a financial instrument as a result of fluctuations in interest rates and market prices. We have established policies, procedures and internal processes governing our management of market risks in the normal course of our business operations.

Market-related Credit Risk

Two primary sources of credit risk inherent in our business are (1) client credit risk related to margin lending and leverage and (2) counterparty credit risk related to securities lending and borrowing. We manage client margin lending and leverage risk by requiring clients to maintain margin collateral in compliance with regulatory and internal guidelines. The risks associated with margin lending and leverage increase during periods of rapid market movements, or in cases where leverage or collateral is concentrated and market movements occur. We monitor required margin levels daily and, pursuant to such guidelines, require our clients to deposit additional collateral, or to reduce positions, when necessary. We continuously monitor client accounts to detect excessive concentration, large orders or positions, patterns of day trading and other activities that may indicate increased risk to us. We manage risks associated with our securities lending and borrowing activities by requiring credit approvals for counterparties, by monitoring the market value of securities loaned and collateral values for securities borrowed on a daily basis and requiring additional cash as collateral for securities loaned or return of collateral for securities borrowed when necessary, and by participating in a risk-sharing program offered through the Options Clearing Corporation.

We are party to interest rate swaps related to our long-term debt, which are subject to counterparty credit risk. Credit risk on derivative financial instruments is managed by limiting activity to approved counterparties that meet a minimum credit rating threshold and by entering into credit support agreements, or by utilizing approved central clearing counterparties registered with the Commodity Futures Trading Commission. Our interest rate swaps require daily collateral coverage, in the form of cash or U.S. Treasury securities, for the aggregate fair value of the interest rate swaps.

52

Interest Rate Risk

As a fundamental part of our brokerage business, we invest in interest-earning assets and are obligated on interest-bearing liabilities. In addition, we earn fees on our bank deposit account arrangements and on money market mutual funds, which are subject to interest rate risk. Changes in interest rates could affect the interest earned on assets differently than interest paid on liabilities. A rising interest rate environment generally results in us earning a larger net interest spread. Conversely, a falling interest rate environment generally results in us earning a smaller net interest spread.

Our most prevalent form of interest rate risk is referred to as "gap" risk. Gap risk occurs when the interest rates we earn on assets change at a different frequency or amount than the interest rates we pay on liabilities. For example, in a low interest rate environment, sharp increases in short-term interest rates could result in net interest spread compression if the yields paid on interest-bearing client balances were to increase faster than our earnings on interest-earning assets. We seek to mitigate interest rate risk by aligning the average duration of interest-earning assets with that of interest-bearing liabilities. As of March 31, 2020, our consolidated duration was 1.5 years. We have an Asset/Liability Committee serve as the governance body with the responsibility of managing interest rate risk, including gap risk.

We use net interest simulation modeling techniques to evaluate the effect that changes in interest rates might have on pre-tax income. Our model includes all interest-sensitive assets and liabilities of the Company and interest-sensitive assets and liabilities associated with bank deposit account arrangements. The simulations involve assumptions that are inherently uncertain and, as a result, cannot precisely predict the impact that changes in interest rates will have on pre-tax income. Actual results may differ from simulated results due to differences in timing and frequency of rate changes, changes in market conditions and changes in management strategy that lead to changes in the mix of interest-sensitive assets and liabilities.

The simulations assume that the asset and liability structure of our Condensed Consolidated Balance Sheet and client bank deposit account balances would not be changed as a result of a simulated change in interest rates. The results of the simulations based on our financial position as of March 31, 2020 indicate that a gradual 1% (100 basis points) increase in interest rates over a 12-month period would result in a range of approximately $325 million to $475 million higher pre-tax income and a gradual 1% (100 basis points) decrease in interest rates over a 12-month period would result in a range of approximately $75 million to $90 million lower pre-tax income, depending largely on the extent and timing of possible increases in payment rates on client cash balances and interest rates charged on client margin balances. The results of the simulations reflect the fact that short-term interest rates are at historically low levels, including the federal funds target rate, which is currently at a range of zero to 0.25%.

Other Market Risks

Substantially all of our revenues and financial instruments are denominated in U.S. dollars. We generally do not enter into derivative transactions, except for hedging purposes.

Item 4. – Controls and Procedures

Disclosure Controls and Procedures

Management, including the Chief Executive Officer and Chief Financial Officer, performed an evaluation of the effectiveness of the Company's disclosure controls and procedures as of March 31, 2020. Management, including the Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of March 31, 2020.

Changes in Internal Control over Financial Reporting

During the second quarter of fiscal year 2020, the Company completed the implementation of a new enterprise resource planning ("ERP") system, migrating its core finance general ledger and human capital management functions.  As a result of the ERP implementation, there were certain changes to processes and procedures, which resulted in material changes to the Company's internal control over financial reporting since management's last assessment of the Company's internal control over financial reporting, which was completed as of September 30, 2019.

There have been no other changes in the Company's internal control over financial reporting during the most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

Item 1A. – Risk Factors

In addition to the other information set forth in this report, you should carefully consider the factors discussed under Item 1A— "Risk Factors" in our annual report on Form 10-K for the year ended September 30, 2019, which could materially affect our business, financial condition and results of operations. The risks described in our Form 10-K are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and results of operations. Except as set forth below, there have been no material changes in the Company's risk factors from those disclosed in our annual report on Form 10-K for the year ended September 30, 2019.

There are a number of risks and uncertainties relating to the COVID-19 pandemic. Because of these risks and uncertainties, we have supplemented the risk factors previously disclosed in our annual report on Form 10-K for the year ended September 30, 2019 as follows:

Risk Factors Relating to Our Business Operations

Economic, social and political conditions and other securities industry risks could adversely affect our business.

Substantially all of our revenues are derived from our securities brokerage business, which generates asset-based revenues and transaction-based revenues. Like other securities brokerage businesses, we are directly affected by economic, social and political conditions, broad trends in business and finance and changes in volume and price levels of securities transactions. Events in global financial markets have from time to time resulted, and may continue to result, in substantial market volatility and changes in client trading volume, and any sustained downturn in general economic conditions or U.S. or foreign financial markets, including equity and debt markets, or continued market volatility or uncertainty could result in reduced client trading volume and order routing revenues. Severe market fluctuations, such as those experienced recently with regard to COVID-19, oil and other commodity prices, concerns over sovereign debt risk, trade policies and tariffs affecting other countries, and those that may arise from global and political tensions or weak economic conditions, may have a direct or indirect negative impact on our trading, net revenues, profitability and growth prospects and otherwise materially adversely affect our business, results of operations, financial condition and cash flows.

At our risk, we rely on external service providers to perform certain key functions.

We rely on a number of external service providers for certain key technology, processing, service and support functions. These include the services of other broker-dealers, market makers, exchanges and clearinghouses to execute and settle client orders. We contract with external providers for futures and foreign exchange clearing. External content providers provide us with financial information, market news, charts, option and stock quotes, research reports and other fundamental data that we offer to clients. These service providers face technological, operational and security risks of their own. A significant failure by any of them, such as improper use or disclosure of our confidential client, employee or Company information, or business disruptions resulting from factors outside of their control, such as the current COVID-19 pandemic, could interrupt our business, subject us to losses and harm our reputation. Also, our external service providers may rely on others, including subcontractors or cloud computing service providers, to provide services to us, which are subject to similar risks.

We evaluate external service providers to verify that they can support the stability of our operations and systems. There is no assurance, however, that we will not experience business interruption or loss due to an act or omission of such a service provider. Any significant failures or security breaches by or of our external service providers or their subcontractors, including any actual or perceived cyberattacks, security breaches, fraud, phishing attacks, acts of vandalism, information security breaches and computer viruses that could result in unauthorized access, misuse, loss or destruction of data, interruption in service or other similar events, could interrupt our business, cause us to incur losses, subject us to fines or litigation and harm our reputation. An interruption in or the cessation of service by any external service provider and our inability to make alternative arrangements in a timely manner could have a material impact on our ability to offer products and services, cause us to incur losses, and could lead to a general loss of customer confidence in our security measures and technology infrastructure.

There is no assurance that our external service providers or their subcontractors will be able to continue to provide these services to meet our current needs in an efficient, cost-effective manner or that they will be able to adequately expand their services to meet our needs in the future. Some external service providers have assets located outside the United States that are integral to their service to us. Their ability to continue providing these services is subject to the risks of unfavorable political, economic, legal and other developments such as public health crises, social or political instability, changes in government policies or changes in laws and regulations.

An interruption in or the cessation of service by an external service provider as a result of systems failures, capacity constraints, financial constraints or problems, unanticipated trading market closures or for any other reason, and our inability to make alternative arrangements in a smooth and timely manner, if at all, could have a material adverse effect on our business, financial condition and results of operations.

54

Public health crises, illnesses, epidemics or pandemics, including the current COVID-19 pandemic and resulting financial market and economic impacts, could materially adversely impact our business, operating results and financial condition.

In December 2019, a novel strain of coronavirus, COVID-19, was reported to have surfaced in Wuhan, China. COVID-19 has since spread rapidly to other countries, including the United States, and the World Health Organization formally declared the COVID-19 outbreak a pandemic in March 2020. The COVID-19 pandemic has caused significant economic dislocation in the United States as many state and local governments have ordered non-essential businesses to close and residents to shelter in place at home. This has resulted in an unprecedented slowdown in economic activity and a related increase in unemployment. Since the outbreak of COVID-19, more than 30 million people have filed claims for unemployment, and stock markets have declined in value. In response to the COVID-19 pandemic, the Federal Reserve Board has reduced the benchmark federal funds rate to a target range of 0% to 0.25%, and the yields on 10 and 30-year U.S. Treasury notes have declined to historic lows. Various state governments and federal agencies are requiring lenders to provide forbearance and other relief to borrowers. Certain industries have been particularly hard-hit, including the hospitality, restaurant, airline and retail industries.

The spread of COVID-19 has caused us to modify our business practices, including with respect to employee travel, employee work locations and participation in meetings, events and conferences. For example, nearly 100% of our employees are now working from home, we have accelerated the implementation of a virtual desktop solution that historically was used in a more limited fashion, and we have shifted resources between our sites and the sites of outsourced vendors with whom we have relationships, among other changes. We may take further actions as may be required by government authorities or that we determine are in the best interests of our employees, clients and business partners.

The extent to which COVID-19 impacts our business will depend on future developments in the United States and around the world, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19 and the actions required to contain and treat it, reactions by companies, clients, investors, governmental entities and financial markets to such actions, and the effect of the pandemic on short- and long-term general economic conditions, among other factors.

Moreover, our future success depends on the skills of our directors, officers and employees, many of whom have held positions with us for many years. The unanticipated loss or unavailability of key employees due to COVID-19 could harm our ability to operate our business or execute our business strategy. We may not be successful in finding and integrating suitable successors in the event of key employee loss or unavailability.

Although we have business continuity plans and other safeguards in place, the COVID-19 pandemic and the related adverse economic consequences could have material adverse effects on our business, financial condition, liquidity, results of operations and cash flows. To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this report and in Item 1A. — "Risk Factors" and elsewhere in our Annual Report on Form 10-K for the year ended September 30, 2019.

Our exposure to credit risk with clients and counterparties could result in losses.

We extend margin credit and leverage to clients, which are collateralized by client cash and securities. We also borrow and lend securities in connection with our broker-dealer business. A significant portion of our net revenues is derived from interest on margin loans. By permitting clients to purchase securities on margin and exercise leverage with options and futures positions, we are subject to risks inherent in extending credit, especially during periods of rapidly declining markets in which the value of the collateral held by us could fall below the amount of a client's indebtedness. These risks are heightened in the current environment due to the significant volatility, uncertainty and economic disruption associated with COVID-19. In addition, in accordance with regulatory guidelines, we collateralize borrowings of securities by depositing cash or securities with lenders. Sharp changes in market values of substantial amounts of securities and the failure by parties to the borrowing transactions to honor their commitments could have adverse effects on our revenues and profitability. We also engage in financial transactions with counterparties, including securities sold under agreements to repurchase, that expose us to credit losses in the event counterparties cannot meet their obligations. We have policies and procedures designed to manage credit risk, but our policies and procedures may not be fully effective.

55

Risk Factor Relating to Owning Our Stock

The market price of our common stock has experienced, and may continue to experience, substantial volatility.

Our common stock, and the U.S. securities markets in general, have been and are subject to substantial price volatility. The price of our common stock has been known to decrease substantially and quickly. Among the factors that may affect our stock price are the following:

• speculation in the investment community or the press about, or actual changes in, our competitive position, organizational structure, executive team, operations, financial condition, financial reporting and results, effectiveness of cost reduction initiatives, or strategic transactions;

• the announcement of new products, services, acquisitions, or dispositions by us or our competitors;

• the pricing structure for products and services offered to customers by us or our competitors;

• our exposure to changes in U.S. monetary policy and its effect on global financial markets and prevailing interest rates;

• sales of a substantial number of shares of our common stock by (i) TD or (ii) J. Joe Ricketts, our founder, and certain members of his family and trusts held for their benefit, who currently have registration rights covering approximately 234 million shares and 52 million shares, respectively, of our common stock; and

• increases or decreases in revenue or earnings, changes in earnings estimates by the investment community, changes in the interest rate environment or in market expectations regarding the interest rate environment and variations between estimated financial results and actual financial results.

Changes in the stock market generally or as it concerns our industry, as well as geopolitical, economic, and business factors unrelated to us, such as public health crises, may also affect our stock price. For example, the financial and other markets have recently experienced extreme volatility, due in large part to the COVID-19 pandemic and its widespread economic impacts. Such volatility has contributed to a significant variance in the market price of our common stock. Continued financial market volatility, and its effect on the market price of our common stock, will largely depend on future developments, which we cannot accurately predict or control.

Because the market price of our common stock can fluctuate significantly, we could become the object of securities class action litigation, which could result in substantial costs and a diversion of management's attention and resources and could have adverse effects on our business and the price of our common stock.

On November 24, 2019, we entered into an Agreement and Plan of Merger (the "Merger Agreement") with The Charles Schwab Corporation ("Schwab"), pursuant to which a wholly-owned subsidiary of Schwab will merge with and into the Company (the "Merger"), with the Company surviving as a wholly-owned subsidiary of Schwab, subject to the terms and conditions set forth therein. There are a number of risks and uncertainties relating to the Merger. Because of these risks and uncertainties, we have supplemented the risk factors previously disclosed in our annual report on Form 10-K for the year ended September 30, 2019, to add the following risk factors:

Risks Related to the Proposed Merger with The Charles Schwab Corporation

Because the exchange ratio pursuant to the Merger Agreement is fixed and the market price of Schwab common stock has fluctuated and will continue to fluctuate, the Company's stockholders cannot be sure of the Merger Consideration they will receive upon completion of the Merger or the value of the Company's common stock they will give up.

Upon completion of the Merger, each share of the Company's common stock outstanding immediately prior to the Merger (except for shares of the Company's common stock held by the Company as treasury stock or by Schwab (other than any fiduciary shares) which will be cancelled without payment) will automatically be converted into the right to receive 1.0837 shares of Schwab common stock. Because the exchange ratio is fixed, the value of the Merger Consideration will depend on the market price of Schwab common stock at the time the Merger is completed. The value of the Merger Consideration has fluctuated since the date of the announcement of the Merger Agreement and will continue to fluctuate. Stock price changes may result from a variety of factors, including, among others, general market and economic conditions, changes in U.S. monetary policy and its effect on global financial markets and on interest rates, changes in Schwab's and the Company's respective businesses, operations and prospects, the recent outbreak of COVID-19, the related disruption to local, regional and global economic activity and financial markets and the impact that any of the foregoing may have on Schwab or the Company and their respective clients and other constituencies, market assessments of the likelihood that the Merger will be completed, the timing of the Merger and regulatory considerations. Many of these factors are beyond Schwab's and the Company's control.

56

The market price of Schwab common stock after the Merger may be affected by factors different from those affecting the market price of the Company's common stock currently.

Upon completion of the Merger, holders of the Company's common stock will become holders of shares of Schwab common stock. The businesses of Schwab differ from those of the Company in important respects, and, accordingly, the results of operations of Schwab after the Merger, as well as the market price of Schwab common stock, may be affected by factors different from those currently affecting the results of operations of the Company.

After completion of the Merger, Schwab may fail to realize the anticipated benefits and cost savings of the Merger, which could adversely affect the value of Schwab common stock.

The success of the Merger will depend, in significant part, on the ability to realize the anticipated benefits and cost savings from combining the businesses of Schwab and the Company. The ability to realize these anticipated benefits and cost savings is subject to certain risks including:

• Schwab's ability to successfully combine the businesses of Schwab and the Company; and

• whether the combined business will perform as expected.

If Schwab is not able to successfully combine the businesses of Schwab and the Company within the anticipated time frame, or at all, the anticipated cost savings and other benefits of the Merger may not be realized fully or at all or may take longer to realize than expected, the combined business may not perform as expected and the value of the Schwab common stock (including the Merger Consideration) may be adversely affected.

Schwab and the Company have operated and, until completion of the Merger, will continue to operate, independently, and there can be no assurances that their businesses can be integrated successfully. It is possible that the integration process could result in the loss of key Schwab or our employees, the loss of customers, the disruption of either company's or both companies' ongoing businesses or in unexpected integration issues, higher than expected integration costs and an overall post-completion integration process that takes longer than originally anticipated. Specifically, the following issues, among others, must be addressed in integrating the operations of Schwab and the Company in order to realize the anticipated benefits of the Merger so the combined business performs as expected:

• combining certain of the companies' operations and corporate functions;

• integrating the companies' technologies;

• integrating and unifying the product offerings and services available to customers;

• identifying and eliminating redundant and underperforming functions and assets;

• harmonizing the companies' operating practices, employee development and compensation programs, internal controls and other policies, procedures and processes;

• maintaining existing agreements with commercial counterparties and avoiding delays in entering into new agreements with prospective commercial counterparties;

• addressing possible differences in business backgrounds, corporate cultures and management philosophies;

• consolidating the companies' administrative and information technology infrastructure; and

• coordinating distribution and marketing efforts.

In addition, at times the attention of certain members of either company's or both companies' management and resources may be focused on completion of the Merger and the integration of the businesses of the two companies and diverted from day-to-day business operations, which may disrupt each company's ongoing business and the business of the combined company.

We may have difficulty attracting, motivating and retaining executives and other employees in light of the Merger.

Uncertainty about the effect of the Merger on our employees may impair our ability to attract, retain and motivate personnel. Employee retention may be particularly challenging during the pendency of the Merger, as employees may experience uncertainty about their future roles with the combined business. If employees depart, the integration of the companies may be more difficult and costly, the combined company's business following the Merger may be harmed, and the ability to realize the anticipated benefits of the Merger may be adversely affected.

Completion of the Merger is subject to many conditions and if these conditions are not satisfied or waived, the Merger will not be completed.

The obligations of Schwab and the Company to complete the Merger are subject to satisfaction or waiver of a number of conditions, including, among others: (i) adoption of the Merger Agreement by the Company's stockholders, including by the stockholders

57

(other than The Toronto-Dominion Bank ("TD"), certain other significant Company stockholders, including J. Joe Ricketts and Marlene Ricketts, and their respective affiliates) of a majority of the outstanding shares of the Company's common stock (other than shares of the Company's common stock held by TD, such other significant Company stockholders and their respective affiliates), (ii) approval of the issuance of Schwab common stock in the Merger by Schwab stockholders, (iii) approval of an amendment to Schwab's certificate of incorporation by Schwab stockholders, (iv) expiration or termination of any applicable waiting period (or extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act") and receipt of specified governmental consents and approvals, (v) receipt of a determination from the Federal Reserve Board in form and substance reasonably satisfactory to Schwab or, as determined by Schwab in its sole discretion, other acceptable confirmation, that the consummation of the Merger will not result in Schwab either (x) being deemed to be "controlled" by TD or (y) being deemed to be in "control" of specified subsidiaries of TD, in each case as such terms are interpreted by the Federal Reserve Board under the Bank Holding Company Act of 1956, as amended, or the Home Owners' Loan Act of 1933, as amended (the "noncontrol determinations"), (vi) absence of any applicable law, order or injunction that prohibits completion of the Merger, (vii) approval for the listing on the New York Stock Exchange of the shares of Schwab common stock to be issued in the Merger, subject only to official notice of issuance, (viii) accuracy of the representations and warranties made in the Merger Agreement by the other party, subject to certain materiality thresholds, (ix) performance in all material respects by the other party of the material obligations required to be performed by it at or prior to completion of the Merger, and (x) the absence of a "material adverse effect" (as defined in the Merger Agreement) on the other party. In certain cases, Schwab's obligation to complete the Merger is further subject to the relevant governmental approvals having been received without the imposition of, and there being no applicable law imposing, a "burdensome condition" (as defined in the Merger Agreement). There can be no assurance that the conditions to the closing of the Merger will be satisfied or waived or that the Merger will be completed.

In order to complete the Merger, Schwab and the Company must make certain governmental filings and obtain certain governmental authorizations, and if such filings and authorizations are not made or granted or are granted with conditions to the parties, completion of the Merger may be jeopardized or the anticipated benefits of the Merger could be reduced.

Completion of the Merger is conditioned upon the expiration or early termination of the waiting periods relating to the Merger under the HSR Act and the required governmental authorizations, including the noncontrol determinations from the Federal Reserve Board. Concurrently with the execution and delivery of the Merger Agreement, Schwab, the Company and TD entered into a separate letter agreement, pursuant to which TD has agreed to modify (i) its voting rights and governance arrangements as contemplated by the Merger Agreement and/or the stockholder agreement entered into between Schwab and TD concurrently with the entry into the Merger Agreement, to be effective as of the closing of the Merger, and/or (ii) the terms of the Insured Deposit Account agreement entered into between Schwab and TD concurrently with the entry into the Merger Agreement, to be effective as of the closing of the Merger, in each case to the extent necessary to obtain the foregoing determinations by the Federal Reserve Board; provided, that TD will not be required to take any action which would result in a loss of its ability to account for its ownership of Schwab common shares (including nonvoting common shares) to be issued to it in the Merger on an equity accounting basis. Although Schwab and the Company have agreed in the Merger Agreement to use their reasonable best efforts, subject to certain limitations, to make certain governmental filings or obtain the required governmental authorizations, as the case may be, there can be no assurance that the relevant waiting periods will expire or that the relevant authorizations will be obtained. In addition, the governmental authorities with or from which these authorizations are required have broad discretion in administering the governing regulations. As a condition to authorization of the Merger, these governmental authorities may impose requirements, limitations or costs or place restrictions on the conduct of the combined company. There can be no assurance that regulators will not impose conditions, terms, obligations or restrictions and that such conditions, terms, obligations or restrictions will not have the effect of delaying completion of the Merger or imposing additional material costs on or materially limiting the revenues of the combined company following the Merger, or otherwise adversely affecting the combined company. In addition, there can be no assurance that these terms, obligations or restrictions will not result in the delay or abandonment of the Merger.

Our business relationships may be subject to disruption due to uncertainty associated with the Merger.

Parties with which we do business may experience uncertainty associated with the transaction, including with respect to current or future business relationships with the Company or the combined business. Our business relationships may be subject to disruption as parties may attempt to negotiate changes in existing business relationships or consider entering into business relationships with parties other than the Company or the combined business. These disruptions could have an adverse effect on the businesses, financial condition, results of operations, cash flows or prospects of the Company or the combined business, including an adverse effect on the ability to realize the anticipated benefits of the Merger. The risk, and adverse effect, of such disruptions could be exacerbated by a delay in completion of the Merger or termination of the Merger Agreement.

The Merger Agreement limits our ability to pursue alternatives to the Merger and may discourage other companies from trying to acquire the Company for greater consideration than what Schwab has agreed to pay.

The Merger Agreement contains provisions that make it more difficult for the Company to sell its business to a party other than Schwab. These provisions include a general prohibition on the Company soliciting any acquisition proposal or offer for a competing transaction. Further, subject to certain exceptions, the Company's board of directors may not withdraw or modify in a manner

58

adverse to Schwab the recommendation of the Company's board of directors in favor of the adoption of the Merger Agreement, and Schwab generally has a right to match any competing acquisition proposals that may be made. Notwithstanding the foregoing, at any time prior to the adoption of the Merger Agreement by the Company's stockholders, the Company's board of directors is permitted to withdraw or modify in a manner adverse to Schwab the recommendation of the Company's board of directors in favor of the adoption of the Merger Agreement in certain circumstances if it determines in good faith that the failure to take such action would be reasonably likely to be inconsistent with its fiduciary duties to the Company's stockholders under applicable law. The Merger Agreement requires that the Company submit the adoption of the Merger Agreement to a vote of the Company's stockholders even if the Company's board of directors changes its recommendation in favor of the adoption of the Merger Agreement in a manner adverse to Schwab.

While the Company believes these provisions and agreements are reasonable and customary and are not preclusive of other offers, the provisions might discourage a third party that has an interest in acquiring all or a significant part of the Company from considering or proposing that acquisition, even if that party were prepared to pay consideration with a higher per-share value than the currently proposed Merger Consideration.

Failure to complete the Merger could negatively impact the stock price and the future business and financial results of the Company.

If the Merger is not completed for any reason, including as a result of Schwab stockholders or the Company's stockholders failing to approve the transaction, the ongoing business of the Company may be adversely affected and, without realizing any of the benefits of having completed the Merger, we would be subject to a number of risks, including the following:

• we may experience negative reactions from the financial markets, including negative impacts on its stock price;

• we may experience negative reactions from its customers, regulators and employees;

• we will be required to pay certain costs relating to the Merger, whether or not the Merger is completed;

• the Merger Agreement places certain restrictions on the conduct of our business prior to completion of the Merger. Such restrictions, the waiver of which is subject to the consent of Schwab (in certain cases, not to be unreasonably withheld, conditioned or delayed), may prevent us from making certain acquisitions, taking certain other specified actions or otherwise pursuing business opportunities during the pendency of the Merger; and

• matters relating to the Merger (including integration planning) will require substantial commitments of time and resources by our management, which would otherwise have been devoted to day-to-day operations and other opportunities that may have been beneficial to us as an independent company.

If the Merger is not completed, the risks described above may materialize and they may adversely affect our business, financial condition, results of operations, cash flows and stock price.

If the Merger Agreement is terminated in certain circumstances, we may be required to pay a termination fee of $950 million to Schwab.

In addition, we could be subject to litigation related to any failure to complete the Merger or related to any enforcement proceeding commenced against the Company to perform its obligations under the Merger Agreement. If the Merger is not completed, these risks may materialize and may adversely affect our business, financial condition, results of operations, cash flows and stock price.

The Schwab common stock to be received by the Company's stockholders upon completion of the Merger will have different rights from shares of the Company's common stock.

Upon completion of the Merger, the Company's stockholders will no longer be stockholders of the Company but will instead become stockholders of Schwab. The Company's stockholders' rights as stockholders will continue to be governed by Delaware law but the terms of Schwab's certificate of incorporation and Schwab's by-laws are in some respects materially different than the terms of the Company's charter and the Company's by-laws, which currently govern the rights of the Company's stockholders.

After the Merger, the Company's stockholders will have a significantly lower ownership and voting interest in Schwab than they currently have in the Company and will exercise less influence over management.

Based on the number of shares of the Company's common stock outstanding as of November 24, 2019, former Company stockholders will own approximately 31% of the outstanding shares of Schwab common stock. Consequently, former Company stockholders will have less influence over the management and policies of Schwab than they currently have over the management and policies of the Company.

59

Lawsuits have been filed against the Company and the Company's board of directors and other lawsuits may be filed against the Company and the Company's board of directors challenging the Merger. An adverse ruling in any such lawsuit may prevent the Merger from being completed.

Six complaints have been filed by purported stockholders of the Company challenging the Merger. The first, a putative class action complaint, was filed by Michael Kent in the United States District Court for the District of Delaware and is captioned Kent v. TD Ameritrade Holding Corporation et al., case number 1:20-cv-00388. The second complaint, filed in the United States District Court for the District of Delaware by Shiva Stein individually, is captioned Stein v. TD Ameritrade Holding Corporation et al., case number 1:20-cv-00410. The third complaint, filed in the United States District Court for the District of New Jersey by Marc Roth individually, is captioned Roth v. TD Ameritrade Holding Corporation et al., case number 2:20-cv-03425. The fourth complaint, filed in the United States District Court for the District of New Jersey by Harold Litwin individually, is captioned Litwin v. TD Ameritrade Holding Corporation et al., case number 2:20-cv-03569. The fifth, a putative class action complaint, filed in the United States District Court for the District of New Jersey by Audrey Bernstein, is captioned Bernstein v. TD Ameritrade Holding Corporation et al., case number 2:20-cv-03695. The sixth complaint, filed in the United States District Court for the Southern District of New York by Glenn Garrison individually, is captioned Garrison v. TD Ameritrade Holding Corporation et al., case number 1:20-cv-02850. The complaints generally allege, among other things, that the defendants named therein authorized the filing of a materially incomplete and misleading registration statement with the SEC. Among other remedies, the complaints seek to enjoin the stockholder vote at the TD Ameritrade special meeting to be held to approve the Merger and related matters and the closing of the Merger, as well as costs and attorneys' fees. The Company believes that the complaints are without merit but is unable to predict the outcome of the ultimate resolution of the lawsuits, or the potential loss, if any, that may result. In addition, a purported stockholder of the Company has made a demand pursuant to Section 220 of the Delaware General Corporation Law to inspect certain books and records of the Company relating to the proposed Merger. There can be no assurances that additional complaints or demands will not be filed or made with respect to the Merger.

One of the conditions to completion of the Merger is the absence of any applicable law (including any order) being in effect that prohibits completion of the Merger. Accordingly, if a plaintiff is successful in obtaining an order prohibiting completion of the Merger, then such order may prevent the Merger from being completed, or from being completed within the expected timeframe.

Schwab and the Company will incur significant transaction and merger-related costs in connection with the Merger.

Schwab and the Company expect to incur a number of non-recurring costs associated with the Merger and combining the operations of the two companies. The substantial majority of non-recurring expenses will be comprised of transaction costs related to the Merger. The significant, non-recurring costs associated with the Merger include, among others, fees and expenses of advisors and representatives, certain employment-related costs relating to employees of the Company, filing fees due in connection with filings required under the HSR Act and filing fees and printing and mailing costs for the joint proxy statement/prospectus related to the transaction. Some of these costs have already been incurred or may be incurred regardless of whether the Merger is consummated. Schwab also will incur transaction fees and costs related to formulating and implementing integration plans with respect to the two companies, including facilities and systems consolidation costs. Additional unanticipated costs may be incurred in the Merger and the integration of the two companies' businesses. Although Schwab expects that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow the combined company to offset integration-related costs over time, this net benefit may not be achieved in the near term, or at all.

The Merger may not be accretive to Schwab's earnings per share, which may negatively affect the market price of Schwab common stock following completion of the Merger.

The issuance of new shares of Schwab common stock in the Merger could have the effect of depressing the market price of shares of Schwab common stock. Based on the anticipated synergies between Schwab and the Company, the Merger is expected to be accretive to Schwab's earnings per share in the third year following completion of the Merger. However, future events and conditions could reduce the accretion that is currently projected or result in the Merger being dilutive to Schwab's earnings per share, including adverse changes in market conditions, additional transaction and integration related costs and other factors such as the failure to realize some or all of the benefits anticipated in the Merger. Any dilution of, or delay of any accretion to, Schwab's earnings per share could cause the price of shares of Schwab common stock to decline or grow at a reduced rate.

EX-10.1

EXHIBIT 10.1    

Term Sheet – Stephen J. Boyle (“Executive”)

Certain capitalized terms used in this Term Sheet have the meanings set forth in Schedule A.

Position: Interim President and CEO

Effective Date: November 20, 2019

Term: Executive shall serve as interim President and CEO from the Effective Date through the earliest to occur of (1) the effective date of the closing (the “Transaction Closing Date”) of the acquisition of TD Ameritrade Holding Corporation (the “Company”) by The Charles Schwab Corporation (“Parent”) pursuant to the terms of the Agreement and Plan of Merger dated November 24, 2019 (the “Merger Agreement”), (2) the date on which Executive ceases serving as the interim President and CEO, and (3) the date on which Executive’s employment with the Company terminates.

The provisions of this Term Sheet shall apply during Executive’s service as interim President and CEO and in the event of a Severance Termination.

Compensation Target: Base Salary:        $800,000

Target Annual

Incentive Award: Executive will be eligible to receive an annual incentive award (the “MIP Award”) with a total blended target opportunity of $4,400,000 for FY2020 (the “FY2020 Target Incentive Opportunity”) and with a total target opportunity of $4,750,000 for FY2021 (the “FY2021 Target Incentive Opportunity”).

Except as provided below in the case of certain terminations of employment, the MIP Award will be 50% in cash and 50% in the form of equity awards. Parent shall determine the amount and form of incentives, if any, following the Transaction Closing Date.

Share Ownership

Requirement: Five (5) times base salary

Vacation: 200 hours of Paid Time Off annually to accrue in accordance with Company PTO Accrual Schedule

Retirement Programs: 401(k) – employer match plus discretionary annual profit sharing

Health and Welfare Plans: Company Benefits Plan Coverage

Company Paid Apartment: The Company agrees to continue to pay for Executive’s New York City apartment in accordance with the arrangement in effect on the Effective Date through the expiration of the current lease on July 13, 2020.

Severance Termination

During the Severance

Protection Period: The provisions of this section shall apply from the Effective Date through the earlier to occur of (1) 12 months after the Transaction Closing Date, and (2) the date on which the Merger Agreement is terminated in accordance with its terms without the occurrence of the Transaction Closing Date, (such period, the “Severance Protection Period”). In the event of Executive’s termination (i) by the Company without Cause or (ii) by Executive for Good Reason, in each case, during the Severance Protection Period, subject to Executive’s execution of a Release of Claims Agreement substantially in the form attached hereto as Exhibit A(the “Release”), Executive will be entitled to the following severance benefits:

• A lump sum cash severance payment equal to $2,875,000 (the “Cash Severance”);

• To the extent not previously paid, a lump sum cash payment in respect the FY2020 MIP Award based on the FY2020 Target Incentive Opportunity, (A) prorated for the portion of FY2020 elapsed through the date of termination, if such termination occurs prior to the Transaction Closing Date or (B) prorated from the Transaction Closing Date through the date of termination, if such termination occurs on or after the Transaction Closing Date (in order to account for the payment of the pro-rata FY2020 MIP Award pursuant to the Merger Agreement);

• If the date of termination occurs in FY2021, a lump sum cash payment in respect of the FY2021 MIP Award based on (A) the FY2021 Target Incentive Opportunity, if the termination is prior to the Transaction Closing Date, or (B) $2,150,000 (or, if greater, the Executive’s incentive opportunity for his role following the Transaction Closing Date), if the termination is after the Transaction Closing Date, in each case, prorated for the portion of FY2021 elapsed through the date of termination;

• A lump sum payment equal to 18 months of the employer portion of premiums for group health plan coverage for active employees based on Executive’s coverage elections in effect on his termination date to assist in payment of COBRA premiums; and

• Terms of existing award agreements govern accelerated vesting for all awarded and unvested equity awards, which for the avoidance of doubt provide for accelerated vesting in the event of involuntary termination upon retirement or within 24 months of a change in control.

Severance Termination

After the Severance

Protection Period: The provisions of this section shall apply after the Severance Protection Period. In the event of Executive’s involuntary termination by the Company without Cause after the expiration of the Severance Protection Period, subject to Executive’s execution of a Release, Executive will be entitled to the following severance benefits:

2

• 4 weeks of base salary for each completed year of service up to a maximum of 104 weeks (2 years)

• 4 weeks of target cash incentive for each completed year of service up to a maximum of 104 weeks (2 years)

• Immediate full vesting of all outstanding RSUs

• A lump sum payment equal to 12 months of the employer portion of premiums for group health plan coverage for active employees based on Executive’s coverage elections in effect on his termination date to assist in payment of COBRA premiums. Executive may elect COBRA coverage for up to a maximum of 18 months or as otherwise provided by law.

For the avoidance of doubt, in the event of Executive’s termination, Executive shall remain entitled to (i) unpaid base salary through the date of termination; (ii) payment for accrued but unused paid time off; (iii) except in the event of a termination for Cause, payment of any earned but unpaid incentive for a previously completed fiscal year; and (iv) and other rights due Executive under any Company policy, plan or other agreement.

All payments and benefits are intended to be exempt from, or comply with, Code section 409A and this Term Sheet will be administered and interpreted accordingly. Payments (and delivery of shares in the case of equity awards) will be made as soon as administratively possible following the Company’s receipt of Executive’s executed and non-revoked Release, provided, however, that if the Company reasonably determines that Code Section 409A will result in the imposition of additional tax upon the earlier payment of any severance or other benefits otherwise due to Executive on or within the 6 month period following Executive’s date of termination, the severance benefits (or shares in the case of equity awards) will accrue during such 6 month period and will become payable (or delivered) in a lump sum payment on the date that is 6 months and 1 day following the date of Executive’s termination (which constitutes a separation from service for purposes of Code Section 409A). All subsequent payments, if any, will be payable as provided above. Any severance payments (and delivery of shares in respect of equity awards) will be subject to applicable withholdings. In no event will the Company pay or reimburse Executive for any taxes or other costs owed by Executive on account of the payments and benefits from this Term Sheet.

Golden Parachute Tax: The provisions of this section shall apply indefinitely following the Effective Date. Executive will either receive the full payments and benefits due to him or a lesser amount so that Executive will not be subject to the golden parachute excise tax under Code Section 4999 as a result of the application of Code Section 280G, whichever results in Executive receiving more on an after-tax basis. No Section 280G excise gross-up will be provided. All determinations to be made by an accounting firm selected by the Company prior to the Transaction Closing Date, and the Company shall cooperate with Executive in good faith in valuing services (including refraining from performing services) to be provided by Executive prior to or following the Transaction

3

Closing Date, such that payments in respect of such services may be considered reasonable compensation for purposes of Code Section 280G.

In addition, in order to mitigate the impact of Code Section 280G on Executive’s change in control related payments and benefits, the Company will accelerate into 2019 the vesting and settlement of 24,304 Company restricted stock units (the “2019 RSUs”) granted on December 5, 2019 and scheduled to vest in equal one-third installments on each of the first three anniversaries of the grant date (each, a “Scheduled Vesting Date”). Such accelerated vesting will be subject to the following conditions, and Executive hereby expressly agrees to such conditions: (1) upon Executive’s termination of employment with the Company and its affiliates prior to the last Scheduled Vesting Date due to Executive’s voluntary resignation or termination for Cause, then Executive shall be obligated to promptly repay to the Company the net after-tax number of shares of Company common stock previously delivered to Executive pursuant to the 2019 RSUs for which the Scheduled Vesting Date has not occurred prior to such termination, (2) Executive shall not be permitted to sell, transfer or otherwise dispose of the net after-tax shares of Company common stock delivered pursuant to the 2019 RSUs unless and until the date on which the 2019 RSUs associated with such shares of Company common stock would have vested under the terms applicable to the 2019 RSUs (either due to the occurrence of a Scheduled Vesting Date or due to Executive’s involuntary termination of employment without Cause, or death or disability), (3) the net after-tax shares of Company common stock delivered pursuant to the 2019 RSUs will bear a transfer restriction legend consistent with the transfer restriction described in the preceding item 2, and (4) after the shares of Company common stock delivered pursuant to the 2019 RSUs are exchanged for shares of Parent common stock in connection with the acquisition of the Company by Parent, the repayment obligations, transfer restriction and transfer restriction legend described in items (1) through (3) will continue to apply to such shares of Parent common stock to the same extent that they applied to the corresponding shares of Company common stock.

Other Agreements: The provisions of this section shall apply indefinitely following the Effective Date. All terms of the Associate Agreement dated March 25, 2015, by and between Executive and the Company (the “Associate Agreement”) are hereby incorporated by reference. Executive hereby expressly acknowledges that he remains bound by the restrictive covenants applicable to him pursuant to the Associate Agreement, including the non-competition covenant contained in Section 5 of the Associate Agreement (the “Non-Competition Covenant”). Further, Executive expressly agrees that, if Executive materially breaches the Non-Competition Covenant, then Executive shall forfeit the right to receive, and/or shall promptly repay to the Company upon demand, the following compensation: (i) Cash Severance, (ii) the FY2020 MIP Award, and (iii) the FY2021 MIP Award.

Further, Executive expressly agrees that this Term Sheet and any and all disputes, controversies or claims between the Executive and the Company and/or Parent shall be governed by, construed and enforced in accordance with the laws of the State of New York without regard to its conflict of laws provisions.

4

In the event of any conflict between the terms of this Term Sheet and the terms of any other agreements to which the Executive may be subject, including, without limitation, the terms of the Offer Summary dated March 25, 2015 (the “Offer Summary”) and the Associate Agreement, by and between Executive and the Company, the terms of this Term Sheet shall govern.

For the avoidance of doubt, this Term Sheet supersedes the Offer Summary, except Executive hereby expressly acknowledges that he remains bound by the following language from the Offer Summary: “Forfeiture Events. The Administrator may specify in an award agreement that the Participant’s rights, payments, and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture, or recoupment upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Such events may include, but shall not be limited to, fraud, breach of a fiduciary duty, restatement of financial statements as a result of fraud or willful errors or omissions, termination of employment for cause, violation of material Company and/or Subsidiary policies, breach of non-competition, confidentiality, or other restrictive covenants that may apply to the Participant, or other conduct by the Participant that is detrimental to the business or reputation of the Company and/or its Subsidiaries.”

For the avoidance of doubt, the Associate Agreement will survive and continue in effect in accordance with its terms, except to the extent it conflicts with the Term Sheet.

Schedule A

CERTAIN DEFINITIONS AND OTHER ADDITIONAL TERMS

As used in this Term Sheet, and unless the context requires a different meaning, the following terms, when capitalized, have the meaning indicated:

“Base Salary” means Executive’s annual rate of base salary as set forth in this Term Sheet or such higher rate as in effect after the Effective Date.

“Cause” means conduct involving one or more of the following: (1) the conviction of Executive of, or plea of nolo contendere by Executive to, a felony that the Board of Directors of Company or Parent reasonably believes has had or will have a material detrimental effect on Company’s or Parent’s reputation or business; (2) any act of personal dishonesty taken by Executive in connection with his responsibilities as an employee of Company or Parent with the intention or reasonable expectation that such action may result in the substantial personal enrichment of Executive; (3) breach of any fiduciary duty owed to the Company or Parent by Executive that has a material detrimental effect on the Company’s or Parent’s reputation or business; (4) the willful, substantial and continuing failure of Executive to perform the reasonable duties of his position (which duties are consistent with his position as Interim President or CEO of the Company, as applicable) for a period of at least thirty (30) days following written notice from the Board of Company or Parent to the Executive that describes the basis for the Board’s belief that Executive has not substantially performed his reasonable duties for reasons other than illness or incapacity; (5) Executive being found liable in any Securities and Exchange Commission or other civil or criminal securities law action or entering any cease and desist order with respect to such action (regardless of whether or not Executive admits or denies liability); willful misconduct, gross negligence, fraud or embezzlement, in each case that results in substantial, material harm to Company or Parent; (6) Executive (a) obstructing or impeding, (b) endeavoring to influence, obstruct or impede, or (c) failing to materially cooperate with, any investigation authorized by the Board of Directors of Company or Parent or any governmental or self-regulatory entity (an “Investigation”). However, Executive’s failure to waive attorney-client privilege relating to communications with Executive’s own attorney in connection with an Investigation will not constitute “Cause” and (7) Executive’s disqualification or bar by any governmental or self-regulatory authority from serving in the capacity contemplated by this Term Sheet or Executive’s loss of any governmental or self-regulatory license that is reasonably necessary for Executive to perform his responsibilities to Company under this Term Sheet, if (a) the disqualification, bar or loss continues for more than thirty (30) days, and (b) during that period Company uses its good faith efforts to cause the disqualification or bar to be lifted or the license replaced. While any disqualification, bar or loss continues during Executive’s employment, Executive will serve in the capacity contemplated by this Term Sheet to whatever extent legally permissible and, if Executive’s employment is not permissible, Executive will be placed on leave (which will be paid to the extent legally permissible).

“Change in Control” has the same meaning as under the Company’s Long-Term Incentive Plan, which is the Company’s stockholder-approved equity compensation plan.

“Code” mean the Internal Revenue Code of 1986, as amended, and the regulations and guidance thereunder.

“Good Reason” shall mean Executive’s voluntary resignation after the occurrence of any of the following events or actions taken by the Company or any of its Affiliates without Executive’s written consent: (i) a material diminution in Executive’s title or position with the Company, which for purposes hereof shall occur if (A) prior to the Transaction Closing Date, Executive’s title or position are changed such that he ceases serving as Interim President and CEO of the Company and is not immediately reinstated to his prior position of Chief Financial Officer of the Company; or (B) during the one-year

6

period commencing on the Transaction Closing Date, Executive is not serving in the position of Chief Financial Officer of the Company or other executive role of the Company with (x) a base salary of not less than $550,000, and (y) a total annual incentive compensation opportunity (comprised of cash and long-term incentive) that is not materially less than $2,150,000, and; or (ii) during the one-year period following the Transaction Closing Date, Executive’s designated work location is changed to a location that is greater than fifty (50) miles from that in effect immediately prior to the Transaction Closing Date.

In order to invoke a termination for Good Reason, Executive must (i) provide the Company and Parent with written notice within ninety (90) days of the event that Executive believes constitutes Good Reason specifically identifying the acts or omissions constituting the grounds for Good Reason, (ii) provide a reasonable cure period of not less than thirty (30) days following Executive’s submission of the written notice, and (iii) actually resign from employment within ninety (90) days following the expiration of the cure period if the applicable event is not cured.

Exhibit A

FORM OF RELEASE

THIS RELEASE (this “Release”) is entered into between Stephen J. Boyle (“Executive”) and TD Ameritrade Holding Corporation (the “Company”) for the benefit of the Company and its affiliates and their respective successors, including The Charles Schwab Corporation (“Parent”). The entering into and non-revocation of this Release is a condition to Executive’s right to receive certain payments and benefits under the Term Sheet entered into by and between Executive and the Company, dated as of [_____________], 20__ (the “Term Sheet”).

Fair Value Disclosures

Fair Value Measurement — Definition and Hierarchy

ASC 820-10, Fair Value Measurement, defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date.

ASC 820-10 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability, and are developed based on market data obtained from sources independent of the Company. Unobservable inputs reflect the Company's own assumptions about the assumptions other market participants would use in pricing the asset or liability, and are developed based on the best information available in the circumstances.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, as follows:

• Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. This category includes active exchange-traded funds, money market mutual funds, mutual funds and equity securities.

• Level 2 — Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Such inputs include quoted prices in markets that are not active, quoted prices for similar assets and liabilities in active and inactive markets, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means. This category includes most debt securities, U.S. government agency mortgage-backed securities, which consist of Ginnie Mae Conventional Residential Mortgages and Ginnie Mae Home Equity Conversion Mortgages, and other interest-sensitive financial instruments.

• Level 3 — Unobservable inputs for the asset or liability, where there is little, if any, observable market activity or data for the asset or liability.

The following tables present the Company's fair value hierarchy for assets and liabilities measured at fair value on a recurring basis as of March 31, 2020 and September 30, 2019 (dollars in millions):

Valuation Techniques

In general, and where applicable, the Company uses quoted prices in active markets for identical assets or liabilities to determine fair value. This pricing methodology applies to the Company's Level 1 assets and liabilities. If quoted prices in active markets for identical assets and liabilities are not available to determine fair value, then the Company uses quoted prices for similar assets and liabilities or inputs other than the quoted prices that are observable, either directly or indirectly. This pricing methodology applies to the Company's Level 2 assets and liabilities.

Level 2 Measurements:

Debt securities — Fair values for debt securities are based on prices obtained from an independent pricing vendor. The primary inputs to the valuation include quoted prices for similar assets in active markets, quoted prices for identical or similar assets in markets that are not active, contractual cash flows, benchmark yields and credit spreads. The Company validates the vendor pricing by periodically comparing it to pricing from another independent pricing service. The Company has not adjusted prices obtained from the independent pricing vendor for any periods presented in the condensed consolidated financial statements because no significant pricing differences have been observed.

U.S. government agency mortgage-backed securities — Fair values for mortgage-backed securities are based on prices obtained from an independent pricing vendor. The primary inputs to the valuation include quoted prices for similar assets in active markets and in markets that are not active, a market-derived prepayment curve, weighted average yields on the underlying collateral and spreads to benchmark indices. The Company validates the vendor pricing by periodically comparing it to pricing from two other

independent sources. The Company has not adjusted prices obtained from the independent pricing vendor for any periods presented in the condensed consolidated financial statements because no significant pricing differences have been observed.

Interest rate swaps — These derivatives are valued by the Company using a valuation model provided by a third-party service that incorporates interest rate yield curves, which are observable for substantially the full term of the contract. The valuation model is widely accepted in the financial services industry and does not involve significant judgment because most of the inputs are observable in the marketplace. Credit risk is not an input to the valuation because in each case the Company or counterparty has possession of collateral, in the form of cash or U.S. Treasury securities, in amounts equal to or exceeding the fair value of the interest rate swaps. The Company validates the third-party service valuations by comparing them to valuation models provided by the swap counterparties.

Level 3 Measurements:

The Company has no assets or liabilities classified as Level 3 of the fair value hierarchy.

Fair Value of Financial Instruments Not Recorded at Fair Value

Receivable from/payable to brokers, dealers and clearing organizations, receivable from/payable to clients, receivable from/payable to affiliates, other receivables and accounts payable and other liabilities are short-term in nature and accordingly are carried at amounts that approximate fair value. These financial instruments are recorded at or near their respective transaction prices and historically have been settled or converted to cash at approximately that value (categorized as Level 2 of the fair value hierarchy).

Cash and investments segregated and on deposit for regulatory purposes includes reverse repurchase agreements (securities purchased under agreements to resell). Reverse repurchase agreements are treated as collateralized financing transactions and are carried at amounts at which the securities will subsequently be resold, plus accrued interest. The Company's reverse repurchase agreements generally have a maturity of seven days and are collateralized by securities in amounts exceeding the carrying value of the resale agreements. Accordingly, the carrying value of reverse repurchase agreements approximates fair value (categorized as Level 2 of the fair value hierarchy). Cash and investments segregated and on deposit for regulatory purposes also includes cash held in demand deposit accounts and on deposit with futures commission merchants, for which the carrying values approximate the fair value (categorized as Level 1 of the fair value hierarchy). See Note 3 for a summary of cash and investments segregated and on deposit for regulatory purposes.

Securities sold under agreements to repurchase (repurchase agreements) included within other borrowings — Under repurchase agreements the Company receives cash from the counterparties and provides U.S. Treasury securities as collateral. The obligations to repurchase securities sold are reflected as a liability on the Condensed Consolidated Balance Sheets. Repurchase agreements are treated as collateralized financing transactions and are carried at amounts at which the securities will subsequently be repurchased, plus accrued interest. The Company's repurchase agreements are short-term in nature and accordingly the carrying value is a reasonable estimate of fair value (categorized as Level 2 of the fair value hierarchy).

Long-term debt — As of March 31, 2020, the Company's Senior Notes had an aggregate estimated fair value, based on quoted market prices (categorized as Level 1 of the fair value hierarchy), of approximately $3.58 billion, compared to the aggregate carrying value of the Senior Notes on the Condensed Consolidated Balance Sheet of $3.72 billion. As of September 30, 2019, the Company's Senior Notes had an aggregate estimated fair value, based on quoted market prices, of approximately $3.67 billion, compared to the aggregate carrying value of the Senior Notes on the Condensed Consolidated Balance Sheet of $3.59 billion.

Leases [Abstract]

Leases

Leases

The Company enters into various non-cancelable operating leases for certain facilities, including corporate offices, retail branches and data centers. The Company determines if an arrangement is a lease at inception. Operating leases with an initial term of 12 months or less are not recorded on the balance sheet and the related lease expense is recognized on a straight-line basis over the lease term. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement or remeasurement date of a lease based on the present value of lease payments over the lease term. The Company utilizes an incremental borrowing rate to determine the present value of lease payments for each lease, as the lease agreements do not provide an implicit rate. The estimated incremental borrowing rate reflects a secured rate and is based on the term of the lease and the interest rate environment at the lease commencement or remeasurement date. Operating lease ROU assets include (1) lease payments made at or before the commencement date and (2) initial indirect costs; and exclude lease incentives. The Company's lease terms may include options to extend or terminate the lease. Only those renewal and termination options which the Company is reasonably certain of exercising are included in the calculation of the lease liability.

(1) Effective October 3, 2019, the Company reduced its online exchange-listed stock, exchange traded funds (ETF) (domestic and Canadian) and option trade commissions from $6.95 to $0 per trade (plus $0.65 per contract and no exercise or assignment fees on option trades).

The amount of revenue recognized by the Company is measured based on the consideration specified in contracts with its clients. The Company recognizes revenue when a performance obligation is satisfied over time as the services are performed or at a point in time depending on the nature of the services provided as further discussed below.

Asset-Based Revenues

Asset-based revenues consists of bank deposit account fees, net interest revenue and investment product fees. The primary factors driving the Company's asset-based revenues are average balances and average rates. Average balances consist primarily of average client bank deposit account balances, average client margin balances, average segregated cash balances, average client credit balances, average fee-based investment balances and average securities borrowing and lending balances. Average rates consist of the average interest rates and fees earned and paid on such balances.

Bank deposit account fees

Bank deposit account fees consists of revenues earned and recognized over time resulting from a sweep program that is offered to eligible clients of the Company whereby clients' uninvested cash is swept off-balance sheet to FDIC-insured (up to specified limits) accounts with Sweep Program Counterparties participating in the program. These revenues are based on the return of floating-rate and fixed-rate notional investments, less the actual interest paid to clients and other applicable fees. Bank deposit account fees are collected from the Sweep Program Counterparties on a monthly basis. See "Insured Deposit Account Agreement" in Note 15 for a description of the sweep arrangement between the Company and TD.

Net interest revenue

Net interest revenue, which is generated from financial instruments covered by various other areas of GAAP, is not within the scope of ASC Topic 606, Revenue from Contracts with Customers, and is included in the table above to reconcile to net revenues disclosed within the Condensed Consolidated Statements of Income. Net interest revenue primarily consists of income generated by interest charged to clients on margin balances, net interest revenue from securities borrowed and securities loaned transactions and interest earned on client cash, net of interest paid to clients on their credit balances.

Investment product fees

Investment product fee revenue consists of revenues earned and recorded over time on client assets invested in money market mutual funds, other mutual funds and certain investment programs. Investment product fees also includes fees earned on client assets managed by independent registered investment advisors ("RIAs") utilizing the Company's trading and investing platforms. Investment product fees are collected from clients and RIAs on a monthly or quarterly basis. Primary revenue sources within investment product fees are described below.

The following tables present the significant components of investment product fees for the periods indicated (dollars in millions):

	Three Months Ended March 31,

Investment product fees:
Mutual fund service fees	$	79	$	68
Investment program fees	63		61

Investment product fees:
Mutual funds service fees	$	160	$	135
Investment program fees	127		129
Other	3		16
Total investment product fees	$	290	$	280

Mutual fund service fees includes shareholder services fees and SEC Rule 12b-1 service and distribution fees. Shareholder services fees are earned on the Company's client assets invested in money market mutual funds and other mutual funds for record-keeping and administrative services provided to these funds. The Company earns SEC Rule 12b-1 service and distribution fees for marketing and distribution services provided to these funds. The fees earned are based on contractual rates applied to the average daily net asset value of eligible shares of a respective fund held by the Company's clients. Shareholder services fees are earned over time and collected from the funds on a monthly or quarterly basis. SEC Rule 12b-1 fees are also earned over time and collected from the funds on a monthly or quarterly basis, as the variable consideration of a transaction price is no longer constrained and the value of consideration can be determined as discussed previously.

Investment program fees are earned through fees charged to clients enrolled in product offerings which are actively managed by TD Ameritrade Investment Management, LLC, a wholly-owned subsidiary of the Company. These fees are earned over time and are based on contractual rates applied to asset balances held by the Company's clients in these product offerings. Certain program fees are based on quarter-end balances and are collected from clients in advance, at the beginning of each calendar quarter. Revenues collected on a quarterly basis, less refunds for clients ceasing participation in the program, are recognized during the quarter as performance obligations are satisfied. Other program fees are based on average daily asset balances and collected from clients on a monthly basis.

The Company also earns investment program fees through referral and asset-based program fees on its client assets managed by independent RIAs utilizing the Company's platform. These fees are earned based on contractual rates applied to the client's average daily asset balances under management. Referral fees are earned over time and collected from the independent RIAs on a monthly or quarterly basis, as the variable consideration of a transaction price is no longer constrained and the value of consideration can be determined as discussed previously. Asset-based program fees are also earned over time and collected from the independent RIAs on a monthly or quarterly basis.

Transaction-Based Revenues

Transaction-based revenues primarily consists of order routing revenue and trading commissions earned on trade execution, net of promotional allowances. The primary factors driving the Company's transaction-based revenues are total trades and average commissions per trade. Commission rates are based on rates established by the Company, which vary by type of trade. Transaction-based revenues are earned and recognized at a point in time, on a trade-date basis, as clients execute trades. These trades are generally settled and trading commissions are collected from the Company's clients within one to two business days after the trade

date. Order routing revenues are generated from arrangements with market centers to receive cash payments and/or rebates in exchange for routing orders to these firms for execution and are generally collected from the market centers on a monthly basis. Securities owned by clients, including those that collateralize margin or similar transactions, are not reflected in the accompanying condensed consolidated financial statements.

Other Revenues

Other revenues primarily include proxy income, solicit and tender fees and other fees charged for ancillary services provided by the Company to its clients. In addition, other revenues include fair market value adjustments and gains/losses associated with investments held by the Company's broker-dealer subsidiaries. Other revenues generated from investments is covered by various other areas of GAAP, is not within the scope of ASC 606 and is included in the table above to reconcile to net revenues disclosed within the Condensed Consolidated Statements of Income. Proxy fee income is earned and collected at a point in time when the Company distributes proxy statements to its clients on behalf of a registrant and the revenue is based on the volume of proxies distributed and the rate per unit charged to each registrant. Solicit and tender fees are earned and collected from clients at a point in time when the Company has satisfied its obligation to maintain its client accounts holding securities affected by corporate actions.

Contract Balances

The following table presents the opening and closing balances of the Company's receivables from contracts with clients that are within the scope of ASC 606 on the Condensed Consolidated Balance Sheets (dollars in millions):

	Contract Balances
	Receivable from Clients		Receivable from Affiliates			Other Receivables		Total Receivables from Contracts with Clients
Opening balance, September 30, 2019	$	25	$	7		$	125	$	157
Closing balance, March 31, 2020	26		3			183		212
Increase (decrease)	$	1	$	(4	)	$	58	$	55

The difference between the opening and closing balances of the Company's total receivables from contracts with clients primarily results from the timing difference between the Company's performance and the receipt of payments. No other significant contract assets or liabilities exist as of March 31, 2020 and September 30, 2019.

Unsatisfied Performance Obligations

The Company does not have any unsatisfied performance obligations subject to a practical expedient election under ASC 606.

Transactions with TD and its Affiliates

As a result of the Company's acquisition of TD Waterhouse Group, Inc. during fiscal year 2006, TD became an affiliate of the Company. TD owned approximately 43% of the Company's common stock as of March 31, 2020. Pursuant to the stockholders agreement between TD and the Company, TD has the right to designate five of the twelve members of the Company's board of directors. The Company transacts business and has extensive relationships with TD and certain of its affiliates. Transactions with TD and its affiliates are discussed and summarized below.

Insured Deposit Account Agreement

The Company is party to an insured deposit account ("IDA") agreement with TD Bank USA, N.A. ("TD Bank USA"), TD Bank, N.A. and TD. Under the IDA agreement, TD Bank USA and TD Bank, N.A. (together, the "TD Depository Institutions") make available to clients of the Company FDIC-insured (up to specified limits) money market deposit accounts as either designated sweep vehicles or as non-sweep deposit accounts. The Company provides marketing, recordkeeping and support services for the TD Depository Institutions with respect to the money market deposit accounts. In exchange for providing these services, the TD Depository Institutions pay the Company an aggregate marketing fee based on the weighted average yield earned on the client IDA assets, less the actual interest paid to clients, a servicing fee to the TD Depository Institutions and the cost of FDIC insurance premiums.

The current IDA agreement became effective as of January 1, 2013 and had an initial term expiring July 1, 2018. It is automatically renewable for successive five-year terms, provided that it may be terminated by either the Company or the TD Depository Institutions by providing written notice of non-renewal at least two years prior to the initial expiration date or the expiration date

of any subsequent renewal period. As of July 1, 2016, notice of non-renewal was not provided by either party; therefore, the IDA agreement was automatically renewed for an additional five-year term on July 1, 2018.

The fee earned on the IDA agreement is calculated based on two primary components: (1) the yield on fixed-rate notional investments, based on prevailing fixed rates for identical balances and maturities in the interest rate swap market (generally LIBOR-based) at the time such investments were added to the IDA portfolio (including any adjustments required to adjust the variable rate leg of such swaps to a one-month reset frequency and the overall swap payment frequency to monthly) and (2) the yield on floating-rate investments. As of March 31, 2020, the IDA portfolio was comprised of approximately 67% fixed-rate notional investments and 33% floating-rate investments.

The IDA agreement provides that the Company may designate amounts and maturity dates for the fixed-rate notional investments in the IDA portfolio, subject to certain limitations. For example, if the Company designates that $100 million of deposits be invested in 5-year fixed-rate investments, and on the day such investment is confirmed by the TD Depository Institutions the prevailing fixed yield for the applicable 5-year U.S. dollar LIBOR-based swaps is 1.45%, then the Company will earn a gross fixed yield of 1.45% on that portion of the portfolio (before any deductions for interest paid to clients, the servicing fee to the TD Depository Institutions and the cost of FDIC insurance premiums). In the event that (1) the federal funds effective rate is established at 0.75% or greater and (2) the rate on 5-year U.S. dollar interest rate swaps is equal to or greater than 1.50% for 20 consecutive business days, then the rate earned by the Company on new fixed-rate notional investments will be reduced by 20% of the excess of the 5-year U.S. dollar swap rate over 1.50%, up to a maximum of 0.10%.

The yield on floating-rate investments is calculated daily based on the greater of the following rates published by the Federal Reserve: (1) the interest rate paid by Federal Reserve Banks on balances held in excess of required reserve balances and contractual clearing balances under Regulation D and (2) the daily effective federal funds rate.

The interest rates paid to clients are set by the TD Depository Institutions and are not linked to any index. The servicing fee to the TD Depository Institutions under the IDA agreement is equal to 25 basis points on the aggregate average daily balance in the IDA accounts, subject to adjustment as it relates to deposits of less than or equal to $20 billion kept in floating-rate investments or in fixed-rate notional investments with a maturity of up to 24 months ("short-term fixed-rate investments"). For such floating-rate and short-term fixed-rate investments, the servicing fee is equal to the difference of the interest rate earned on the investments less the FDIC premiums paid (in basis points), divided by two. The servicing fee has a floor of 3 basis points (subject to adjustment from time to time to reflect material changes to the TD Depository Institutions' leverage costs) and a maximum of 25 basis points.

In the event the marketing fee computation results in a negative amount, the Company must pay the TD Depository Institutions the negative amount. This effectively results in the Company guaranteeing the TD Depository Institutions revenue equal to the servicing fee on the IDA agreement, plus the reimbursement of FDIC insurance premiums. The marketing fee computation under the IDA agreement is affected by many variables, including the type, duration, principal balance and yield of the fixed-rate and floating-rate investments, the prevailing interest rate environment, the amount of client deposits and the yield paid on client deposits. Because a negative marketing fee computation would arise only if there were extraordinary movements in many of these variables, the maximum potential amount of future payments the Company could be required to make under this arrangement cannot be reasonably estimated. Management believes the likelihood that the marketing fee calculation would result in a negative amount is remote. Accordingly, no contingent liability is carried on the Condensed Consolidated Balance Sheets for the IDA agreement. In the event the Company withdraws a notional investment prior to its maturity, the Company is required to reimburse the TD Depository Institutions an amount equal to the economic replacement value of the investment, as defined in the IDA agreement. See "General Contingencies" in Note 9 for a discussion of how the Company mitigates the risk of losses due to the early withdrawal of fixed-rate notional investments.

In addition, the Company has various other services agreements and transactions with TD and its affiliates. The following tables summarize revenues and expenses resulting from transactions with TD and its affiliates for the periods indicated (dollars in millions):

Receivables from and payables to TD affiliates resulting from client cash sweep activity are generally settled in cash the next business day. Other receivables from and payables to affiliates of TD are generally settled in cash on a monthly basis.

TD, along with other financial institutions, is participating as a lender under the Parent Revolving Facility and the TDAC Revolving Facilities. For additional information regarding the Company's revolving facilities, see Note 7, Long-term Debt and Other Borrowings. As of March 31, 2020 and September 30, 2019, the total lending commitment received from TD under these credit facilities was $221 million.

Senior Notes — As of March 31, 2020 and September 30, 2019, the Company had $3.55 billion aggregate principal amount of unsecured Senior Notes (together, the "Senior Notes"). The fixed rate and variable rate Senior Notes pay interest semi-annually and quarterly, respectively, in arrears. Key information about the Senior Notes outstanding is summarized in the following table (dollars in millions):

Description	Date Issued	Maturity Date	Aggregate Principal	Interest Rate
2021 Notes	October 30, 2018	November 1, 2021	$600	Variable
2022 Notes	March 4, 2015	April 1, 2022	$750	2.950%

2025 Notes	October 17, 2014	April 1, 2025	$500	3.625%

Lines of Credit — TD Ameritrade Clearing, Inc. ("TDAC"), a clearing broker-dealer subsidiary of the Company, utilizes secured uncommitted lines of credit for short-term liquidity. Under these secured uncommitted lines, TDAC borrows on either a demand or short-term basis from two unaffiliated banks and pledges client margin securities as collateral. Advances under the secured uncommitted lines are dependent on TDAC having acceptable collateral as determined by each secured uncommitted credit agreement. At March 31, 2020, the terms of the secured uncommitted credit agreements do not specify borrowing limits. The availability of TDAC's secured uncommitted lines is subject to approval by the individual banks each time an advance is requested and may be denied. There were no borrowings outstanding under the secured uncommitted lines of credit as of March 31, 2020 and September 30, 2019.

Securities Sold Under Agreements to Repurchase (repurchase agreements) — Under repurchase agreements, the Company receives cash from the counterparty and provides U.S. government debt securities as collateral. The Company's repurchase agreements generally mature between seven and 90 days following the transaction date and are accounted for as secured borrowings. The remaining contractual maturities of the repurchase agreements with outstanding balances as of March 31, 2020 were less than seven days. The weighted average interest rate on the balances outstanding as of March 31, 2020 was 0.19%. There were no borrowings outstanding under repurchase agreements as of September 30, 2019. See "General Contingencies" in Note 9 for a discussion of the potential risks associated with repurchase agreements and how the Company mitigates those risks.

Fair Value Hedging — The Company is exposed to changes in the fair value of its fixed-rate Senior Notes resulting from interest rate fluctuations. To hedge a vast majority of this exposure, the Company has entered into fixed-for-variable interest rate swaps on each of the 2022 Notes, 2025 Notes, 2027 Notes and 2029 Notes (together, the "Hedged Senior Notes"). Each fixed-for-variable interest rate swap has a notional amount and a maturity date matching the aggregate principal amount and maturity date, respectively, for each of the respective Hedged Senior Notes.

The interest rate swaps effectively change the fixed-rate interest on the Hedged Senior Notes to variable-rate interest. Under the terms of the interest rate swap agreements, the Company receives semi-annual fixed-rate interest payments based on the same rates applicable to the Hedged Senior Notes, and makes quarterly variable-rate interest payments based on three-month LIBOR plus (1) 0.9486% for the swap on the 2022 Notes, (2) 1.1022% for the swap on the 2025 Notes, (3) 1.0340% for the swap on the 2027 Notes and (4) 1.2000% for the swap on the 2029 Notes. As of March 31, 2020, the weighted average effective interest rate on the aggregate principal balance of the Senior Notes was 2.92%.

The interest rate swaps are accounted for as fair value hedges and qualify for the shortcut method of accounting. Changes in the payment of interest resulting from the interest rate swaps are recorded in interest on borrowings on the Condensed Consolidated Statements of Income. Changes in fair value of the interest rate swaps are completely offset by changes in fair value of the related notes, resulting in no effect on net income. The following table summarizes gains and losses resulting from changes in the fair value of interest rate swaps designated as fair value hedges and the hedged fixed-rate debt for the periods indicated (dollars in millions):

	Three Months Ended March 31,						Six Months Ended March 31,
	2020			2019			2020			2019

Gain (loss) on fair value of hedged fixed-rate debt	(165		)	(34		)	(125		)	(86		)
Net gain (loss) recorded in interest on borrowings	$	—		$	—		$	—		$	—

Balance Sheet Impact of Hedging Instruments — The following table summarizes the classification and the fair value of outstanding derivatives designated as hedging instruments on the Condensed Consolidated Balance Sheets (dollars in millions):

	March 31, 2020		September 30, 2019
Pay-variable interest rate swaps designated as fair value hedges:
Other assets	$	193	$	71
Accounts payable and other liabilities	$	—	$	(3	)

The interest rate swaps are subject to counterparty credit risk. Credit risk is managed by limiting activity to approved counterparties that meet a minimum credit rating threshold, by entering into credit support agreements, or by utilizing approved central clearing counterparties registered with the Commodity Futures Trading Commission ("CFTC"). The interest rate swaps require daily collateral coverage, in the form of cash or U.S. Treasury securities, for the aggregate fair value of the interest rate swaps (including accrued interest). As of March 31, 2020 and September 30, 2019, the pay-variable interest rate swap counterparties had pledged $219 million and $86 million of collateral, respectively, to the Company in the form of cash. A liability for collateral pledged to the Company in the form of cash is recorded in accounts payable and other liabilities on the Condensed Consolidated Balance Sheets. As of September 30, 2019, the Company had pledged $3 million of collateral to the pay-variable interest rate swap counterparties in the form of cash. An asset for collateral pledged to the swap counterparties in the form of cash is recorded in other receivables on the Condensed Consolidated Balance Sheets.

TD Ameritrade Holding Corporation Senior Revolving Credit Facility — On April 21, 2017, the Parent entered into a credit agreement consisting of a senior unsecured committed revolving credit facility in the aggregate principal amount of $300 million (the "Parent Revolving Facility"). The maturity date of the Parent Revolving Facility is April 21, 2022. The obligations under the Parent Revolving Facility are not guaranteed by any subsidiary of the Parent.

The applicable interest rate under the Parent Revolving Facility is calculated as a per annum rate equal to, at the option of the Parent, (1) LIBOR plus an interest rate margin ("Parent Eurodollar loans") or (2) (i) the highest of (x) the prime rate, (y) the federal funds effective rate (or, if the federal funds effective rate is unavailable, the overnight bank funding rate) plus 0.50% or (z) the eurodollar rate assuming a one-month interest period plus 1.00%, plus (ii) an interest rate margin ("ABR loans"). The interest rate margin ranges from 0.875% to 1.50% for Parent Eurodollar loans and from 0% to 0.50% for ABR loans, determined by reference to the Company's public debt ratings. The Parent is obligated to pay a commitment fee ranging from 0.08% to 0.20% on any unused amount of the Parent Revolving Facility, determined by reference to the Company's public debt ratings. There were no borrowings outstanding under the Parent Revolving Facility as of March 31, 2020 and September 30, 2019. As of March 31, 2020, the interest rate margin would have been 1.125% for Parent Eurodollar loans and 0.125% for ABR loans, and the commitment fee was 0.125%, each determined by reference to the Company's public debt ratings.

TD Ameritrade Clearing, Inc. Senior Revolving Credit Facilities — As of March 31, 2020, TDAC had access to two senior unsecured committed revolving credit facilities with an aggregate principal amount of $1.45 billion, consisting of a $600 million (the "$600 Million Revolving Facility") and an $850 million (the "$850 Million Revolving Facility") senior revolving facility (together, the "TDAC Revolving Facilities"). The maturity dates of the $600 Million Revolving Facility and the $850 Million Revolving Facility are April 21, 2022 and May 14, 2020, respectively. On April 21, 2020, TDAC entered into an amendment to the $850 million Revolving Facility, which provides for a senior unsecured revolving credit facility in the aggregate principal amount of $850 million that matures on April 20, 2021 (the "Amended Credit Agreement"). For additional information regarding the Amended Credit Agreement, see Note 16, Subsequent Event.

The applicable interest rate under each of the TDAC Revolving Facilities is calculated as a per annum rate equal to, at the option of TDAC, (1) LIBOR plus an interest rate margin ("TDAC Eurodollar loans") or (2) the federal funds effective rate plus an interest rate margin ("Federal Funds Rate loans"). The interest rate margin ranges from 0.75% to 1.25% for both TDAC Eurodollar loans and Federal Funds Rate loans, determined by reference to the Company's public debt ratings. TDAC is obligated to pay commitment fees ranging from 0.07% to 0.175% and from 0.06% to 0.125% on any unused amounts of the $600 Million Revolving Facility and the $850 Million Revolving Facility, respectively, each determined by reference to the Company's public debt ratings. There were no borrowings outstanding under the TDAC Revolving Facilities as of March 31, 2020 and September 30, 2019. As of March 31, 2020, the interest rate margin under the TDAC Revolving Facilities would have been 1.00% for both TDAC Eurodollar loans and Federal Funds Rate loans, determined by reference to the Company's public debt ratings. As of March 31, 2020, the commitment fees under the $600 Million Revolving Facility and the $850 Million Revolving Facility were 0.10% and 0.08%, respectively, each determined by reference to the Company's public debt ratings.

Offsetting [Abstract]

Offsetting Assets and Liabilities

Offsetting Assets and Liabilities

Substantially all of the Company's securities sold under agreements to repurchase (repurchase agreements), reverse repurchase agreements, securities borrowing and securities lending activity and derivative financial instruments are transacted under master agreements that may allow for net settlement in the ordinary course of business, as well as offsetting of all contracts with a given counterparty in the event of default by one of the parties. However, for financial statement purposes, the Company does not net balances related to these financial instruments.

The following tables present information about the potential effect of rights of setoff associated with the Company's recognized assets and liabilities as of March 31, 2020 and September 30, 2019 (dollars in millions):

Basis of Presentation

Basis of Presentation

The condensed consolidated financial statements include the accounts of TD Ameritrade Holding Corporation (the "Parent") and its wholly-owned subsidiaries (collectively, the "Company"). Intercompany balances and transactions have been eliminated.

These financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and, in the opinion of management, reflect all adjustments, which are all of a normal recurring nature, necessary to present fairly the financial position, results of operations and cash flows for the periods presented in conformity with U.S. generally accepted accounting principles ("GAAP"). These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's annual report filed on Form 10-K for the fiscal year ended September 30, 2019.

Recently Adopted & Issued Accounting Pronouncements

Recently Adopted Accounting Pronouncements

ASU 2016-02 — On October 1, 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, Leases, by applying the standard at the adoption date, recognizing a cumulative-effect adjustment to the opening balance of retained earnings. As a result, restated financial information and the additional disclosures required under the new standard will not be provided for the comparative periods presented. The new guidance requires quantitative and qualitative disclosures that provide information about the amounts related to leasing arrangements recorded in the condensed consolidated financial statements. The Company elected a package of practical expedients available under the new guidance, which allows an entity to not reassess prior conclusions related to existing contracts containing leases, lease classification and initial direct costs. In addition, the Company has elected to apply the short-term lease exception for lease arrangements with a maximum term of 12 months or less. Upon the adoption of the lease standard, the Company recognized a right-of-use ("ROU") asset and a lease liability on the Condensed Consolidated Balance Sheet related to non-cancelable operating leases.

The cumulative effect of the changes made to the Company's Condensed Consolidated Balance Sheet as of October 1, 2019 for the adoption of ASU 2016-02 were as follows (dollars in millions):

	Balance at September 30, 2019		Adjustments from Adoption of ASU 2016-02					Balance at October 1, 2019
Assets:
Other assets	$	308	$	341		(1	)	$	649
Liabilities:
Accounts payable and other liabilities	884		342			(2	)	1,226
Stockholders' Equity:
Retained earnings	8,580		(1		)	(3	)	8,579

(1) Adjustments include the following: (a) an increase of $347 million for the recognition of the ROU asset and (b) a decrease of $6 million for lease payments made to lessors at or before the commencement date, which were reclassified to the ROU lease liability upon the adoption of the lease standard.

(2) Adjustments include the following: (a) an increase of $379 million for the recognition of the ROU lease liability and (b) decreases of $30 million for deferred rent and $7 million related to the early termination of lease obligations, which were reclassified to the ROU asset upon the adoption of the lease standard.

(3) Represents the impact of a lease obligation which had no future benefit upon the adoption of the lease standard.

The adoption of this standard did not have a material impact on the Company's results of operations or cash flows. See Note 6 for additional information regarding the Company's operating leases.

Recently Issued Accounting Pronouncements

ASU 2020-04 — In March 2020, the Financial Accounting Standards Board ("FASB") issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting if certain criteria are met. The amendments in ASU 2020-04 provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. This guidance is effective immediately and the amendments may be applied prospectively through December 31, 2022. The Company is evaluating the guidance and the potential impact of adopting ASU 2020-04 on its condensed consolidated financial statements.

ASU 2019-12 — In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The amendments in ASU 2019-12 simplify the accounting for income taxes by removing certain exceptions to the general principles in Accounting Standards Codification ("ASC") Topic 740, Income Taxes. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. ASU 2019-12 will be effective for the Company's fiscal year beginning October 1, 2021, with early adoption permitted. The transition requirements are dependent upon each amendment within this update and will be applied either prospectively or retrospectively. The Company does not expect this ASU to have a material impact on its condensed consolidated financial statements.

ASU 2016-13 — In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments. The main objective of ASU 2016-13 is to provide financial statement users with more decision-useful information about an entity's

expected credit losses on financial instruments and other commitments to extend credit at each reporting date. To achieve this objective, the amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to develop credit loss estimates. Subsequent to issuing ASU 2016-13, the FASB has issued additional standards for the purpose of clarifying certain aspects of ASU 2016-13, as well as providing codification improvements and targeted transition relief under the standard. The subsequently issued ASUs have the same effective date and transition requirements as ASU 2016-13. ASU 2016-13 will be effective for the Company's fiscal year beginning October 1, 2020, using a modified retrospective approach. Early adoption is permitted. The Company is currently assessing the impact this ASU will have on its condensed consolidated financial statements.

Loss Contingencies (ASC) 450

ASC 450, Loss Contingencies, governs the recognition and disclosure of loss contingencies, including potential losses from legal and regulatory matters. ASC 450 categorizes loss contingencies using three terms based on the likelihood of occurrence of events that result in a loss: "probable" means that "the future event or events are likely to occur;" "remote" means that "the chance of the future event or events occurring is slight;" and "reasonably possible" means that "the chance of the future event or events occurring is more than remote but less than likely." Under ASC 450, the Company accrues for losses that are considered both probable and reasonably estimable.

Fair Value Measurement (ASC) 820-10

ASC 820-10, Fair Value Measurement, defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date.

ASC 820-10 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability, and are developed based on market data obtained from sources independent of the Company. Unobservable inputs reflect the Company's own assumptions about the assumptions other market participants would use in pricing the asset or liability, and are developed based on the best information available in the circumstances.

Revenue Recognition (ASC) 606

Mutual fund service fees includes shareholder services fees and SEC Rule 12b-1 service and distribution fees. Shareholder services fees are earned on the Company's client assets invested in money market mutual funds and other mutual funds for record-keeping and administrative services provided to these funds. The Company earns SEC Rule 12b-1 service and distribution fees for marketing and distribution services provided to these funds. The fees earned are based on contractual rates applied to the average daily net asset value of eligible shares of a respective fund held by the Company's clients. Shareholder services fees are earned over time and collected from the funds on a monthly or quarterly basis. SEC Rule 12b-1 fees are also earned over time and collected from the funds on a monthly or quarterly basis, as the variable consideration of a transaction price is no longer constrained and the value of consideration can be determined as discussed previously.

Investment program fees are earned through fees charged to clients enrolled in product offerings which are actively managed by TD Ameritrade Investment Management, LLC, a wholly-owned subsidiary of the Company. These fees are earned over time and are based on contractual rates applied to asset balances held by the Company's clients in these product offerings. Certain program fees are based on quarter-end balances and are collected from clients in advance, at the beginning of each calendar quarter. Revenues collected on a quarterly basis, less refunds for clients ceasing participation in the program, are recognized during the quarter as performance obligations are satisfied. Other program fees are based on average daily asset balances and collected from clients on a monthly basis.

The Company also earns investment program fees through referral and asset-based program fees on its client assets managed by independent RIAs utilizing the Company's platform. These fees are earned based on contractual rates applied to the client's average daily asset balances under management. Referral fees are earned over time and collected from the independent RIAs on a monthly or quarterly basis, as the variable consideration of a transaction price is no longer constrained and the value of consideration can be determined as discussed previously. Asset-based program fees are also earned over time and collected from the independent RIAs on a monthly or quarterly basis.

Transaction-Based Revenues

Transaction-based revenues primarily consists of order routing revenue and trading commissions earned on trade execution, net of promotional allowances. The primary factors driving the Company's transaction-based revenues are total trades and average commissions per trade. Commission rates are based on rates established by the Company, which vary by type of trade. Transaction-based revenues are earned and recognized at a point in time, on a trade-date basis, as clients execute trades. These trades are generally settled and trading commissions are collected from the Company's clients within one to two business days after the trade

date. Order routing revenues are generated from arrangements with market centers to receive cash payments and/or rebates in exchange for routing orders to these firms for execution and are generally collected from the market centers on a monthly basis. Securities owned by clients, including those that collateralize margin or similar transactions, are not reflected in the accompanying condensed consolidated financial statements.

Other Revenues

Other revenues primarily include proxy income, solicit and tender fees and other fees charged for ancillary services provided by the Company to its clients. In addition, other revenues include fair market value adjustments and gains/losses associated with investments held by the Company's broker-dealer subsidiaries. Other revenues generated from investments is covered by various other areas of GAAP, is not within the scope of ASC 606 and is included in the table above to reconcile to net revenues disclosed within the Condensed Consolidated Statements of Income. Proxy fee income is earned and collected at a point in time when the Company distributes proxy statements to its clients on behalf of a registrant and the revenue is based on the volume of proxies distributed and the rate per unit charged to each registrant. Solicit and tender fees are earned and collected from clients at a point in time when the Company has satisfied its obligation to maintain its client accounts holding securities affected by corporate actions.

The amount of revenue recognized by the Company is measured based on the consideration specified in contracts with its clients. The Company recognizes revenue when a performance obligation is satisfied over time as the services are performed or at a point in time depending on the nature of the services provided as further discussed below.

Asset-Based Revenues

Asset-based revenues consists of bank deposit account fees, net interest revenue and investment product fees. The primary factors driving the Company's asset-based revenues are average balances and average rates. Average balances consist primarily of average client bank deposit account balances, average client margin balances, average segregated cash balances, average client credit balances, average fee-based investment balances and average securities borrowing and lending balances. Average rates consist of the average interest rates and fees earned and paid on such balances.

Bank deposit account fees

Bank deposit account fees consists of revenues earned and recognized over time resulting from a sweep program that is offered to eligible clients of the Company whereby clients' uninvested cash is swept off-balance sheet to FDIC-insured (up to specified limits) accounts with Sweep Program Counterparties participating in the program. These revenues are based on the return of floating-rate and fixed-rate notional investments, less the actual interest paid to clients and other applicable fees. Bank deposit account fees are collected from the Sweep Program Counterparties on a monthly basis. See "Insured Deposit Account Agreement" in Note 15 for a description of the sweep arrangement between the Company and TD.

Net interest revenue

Net interest revenue, which is generated from financial instruments covered by various other areas of GAAP, is not within the scope of ASC Topic 606, Revenue from Contracts with Customers, and is included in the table above to reconcile to net revenues disclosed within the Condensed Consolidated Statements of Income. Net interest revenue primarily consists of income generated by interest charged to clients on margin balances, net interest revenue from securities borrowed and securities loaned transactions and interest earned on client cash, net of interest paid to clients on their credit balances.

Investment product fees

Investment product fee revenue consists of revenues earned and recorded over time on client assets invested in money market mutual funds, other mutual funds and certain investment programs. Investment product fees also includes fees earned on client assets managed by independent registered investment advisors ("RIAs") utilizing the Company's trading and investing platforms. Investment product fees are collected from clients and RIAs on a monthly or quarterly basis. Primary revenue sources within investment product fees are described below.

Legal and Regulatory Matters

Order Routing Matters — In 2014, five putative class action complaints were filed regarding TD Ameritrade, Inc.'s routing of client orders and one putative class action was filed regarding Scottrade, Inc.'s routing of client orders. Five of the six cases were dismissed and the United States Court of Appeals, 8th Circuit, affirmed the dismissals in those cases that were appealed. The one remaining case is Roderick Ford (replacing Gerald Klein) v. TD Ameritrade Holding Corporation, et al., Case No. 8:14CV396 (U.S. District Court, District of Nebraska). In the remaining case, plaintiff alleges that, when routing client orders to various market centers, defendants did not seek best execution, and instead routed clients' orders to market venues that paid TD Ameritrade, Inc. the most money for order flow. Plaintiff alleges that defendants made misrepresentations and omissions regarding the Company's order routing practices. The complaint asserts claims of violations of Section 10(b) and 20 of the Exchange Act and SEC Rule 10b-5. The complaint seeks damages, injunctive relief, and other relief. Plaintiff filed a motion for class certification, which defendants opposed. On July 12, 2018, the Magistrate Judge issued findings and a recommendation that plaintiff's motion for class certification be denied. Plaintiff filed objections to the Magistrate Judge's findings and recommendation, which defendants opposed. On September 14, 2018, the District Judge sustained plaintiff's objections, rejected the Magistrate Judge's recommendation and granted plaintiff's motion for class certification. On September 28, 2018, defendants filed a petition requesting that the U.S. Court of Appeals, 8th Circuit, grant an immediate appeal of the District Court's class certification decision. The U.S. Court of Appeals, 8th Circuit, granted defendants' petition on December 18, 2018. Briefing on the appeal is complete. The Securities Industry and Financial Markets Association and the U.S. Chamber of Commerce have filed amicus curiae briefs in support of the Company's appeal. The Company intends to vigorously defend against this lawsuit and is unable to predict the outcome or the timing of the ultimate resolution of the lawsuit, or the potential loss, if any, that may result.

Litigation Relating to the Merger — Six complaints have been filed by purported stockholders of the Company challenging the Merger. The first, a putative class action complaint, was filed by Michael Kent in the United States District Court for the District of Delaware and is captioned Kent v. TD Ameritrade Holding Corporation et al., case number 1:20-cv-00388. The second complaint, filed in the United States District Court for the District of Delaware by Shiva Stein individually, is captioned Stein v. TD Ameritrade Holding Corporation et al., case number 1:20-cv-00410. The third complaint, filed in the United States District Court for the District of New Jersey by Marc Roth individually, is captioned Roth v. TD Ameritrade Holding Corporation et al., case number 2:20-cv-03425. The fourth complaint, filed in the United States District Court for the District of New Jersey by Harold Litwin individually, is captioned Litwin v. TD Ameritrade Holding Corporation et al., case number 2:20-cv-03569. The fifth, a putative class action complaint, filed in the United States District Court for the District of New Jersey by Audrey Bernstein, is captioned Bernstein v. TD Ameritrade Holding Corporation et al., case number 2:20-cv-03695. The sixth complaint, filed in the United States District Court for the Southern District of New York by Glenn Garrison individually, is captioned Garrison v. TD Ameritrade Holding Corporation et al., case number 1:20-cv-02850. The complaints generally allege, among other things, that the defendants named therein authorized the filing of a materially incomplete and misleading registration statement with the SEC. Among other remedies, the complaints seek to enjoin the stockholder vote at the TD Ameritrade special meeting to be held to approve the Merger and related matters and the closing of the Merger, as well as costs and attorneys' fees. The Company believes that the complaints are without merit but is unable to predict the outcome of the ultimate resolution of the lawsuits, or the potential loss, if any, that may result. In addition, a purported stockholder of the Company has made a demand pursuant to Section 220 of the Delaware General Corporation Law to inspect certain books and records of the Company relating to the proposed Merger. There can be no assurances that additional complaints or demands will not be filed or made with respect to the Merger.

Other Legal and Regulatory Matters — The Company is subject to a number of other lawsuits, arbitrations, claims and other legal proceedings in connection with its business. Some of these legal actions include claims for substantial or unspecified compensatory and/or punitive damages. In addition, in the normal course of business, the Company discusses matters with its regulators raised during regulatory examinations or otherwise subject to their inquiry. These matters could result in censures, fines, penalties or other sanctions. ASC 450, Loss Contingencies, governs the recognition and disclosure of loss contingencies, including potential losses from legal and regulatory matters. ASC 450 categorizes loss contingencies using three terms based on the likelihood of occurrence of events that result in a loss: "probable" means that "the future event or events are likely to occur;" "remote" means that "the chance of the future event or events occurring is slight;" and "reasonably possible" means that "the chance of the future event or events occurring is more than remote but less than likely." Under ASC 450, the Company accrues for losses that are considered both probable and reasonably estimable. The Company may incur losses in addition to the amounts accrued where the losses are greater than estimated by management, or for matters for which an unfavorable outcome is considered reasonably possible, but not probable.

The Company estimates that the aggregate range of reasonably possible losses in excess of amounts accrued is from $0 to $65 million as of March 31, 2020. This estimated aggregate range of reasonably possible losses is based upon currently available information for those legal and regulatory matters in which the Company is involved, taking into account the Company's best estimate of reasonably possible losses for those matters as to which an estimate can be made. For certain matters, the Company does not believe an estimate can currently be made, as some matters are in preliminary stages and some matters have no specific

amounts claimed. The Company's estimate involves significant judgment, given the varying stages of the proceedings and the inherent uncertainty of predicting outcomes. The estimated range will change from time to time as the underlying matters, stages of proceedings and available information change. Actual losses may vary significantly from the current estimated range.

The Company believes, based on its current knowledge and after consultation with counsel, that the ultimate disposition of these legal and regulatory matters, individually or in the aggregate, is not likely to have a material adverse effect on the financial condition or cash flows of the Company. However, in light of the uncertainties involved in such matters, the Company is unable to predict the outcome or the timing of the ultimate resolution of these matters, or the potential losses, fines, penalties or equitable relief, if any, that may result, and it is possible that the ultimate resolution of one or more of these matters may be material to the Company's results of operations for a particular reporting period.

Income Taxes

The Company's federal and state income tax returns are subject to examination by taxing authorities. Because the application of tax laws and regulations to many types of transactions is subject to varying interpretations, amounts reported in the condensed consolidated financial statements could be significantly changed at a later date upon final determinations by taxing authorities.

General Contingencies

In the ordinary course of business, there are various contingencies that are not reflected in the condensed consolidated financial statements. These include the Company's broker-dealer and FCM/FDM subsidiaries' client activities involving the execution, settlement and financing of various client securities, options, futures and foreign exchange transactions. These activities may expose the Company to credit risk and losses in the event the clients are unable to fulfill their contractual obligations.

The Company extends margin credit and leverage to its clients. In margin transactions, the Company extends credit to the client, subject to various regulatory and internal margin requirements, collateralized by cash and securities in the client's account. In connection with these activities, the Company also routes client orders for execution and clears client transactions involving the sale of securities not yet purchased ("short sales"). Such margin-related transactions may expose the Company to credit risk in the event a client's assets are not sufficient to fully cover losses that the client may incur. Leverage involves securing a large potential future obligation with a lesser amount of collateral. The risks associated with margin credit and leverage increase during periods of rapid market movements, or in cases where leverage or collateral is concentrated and market movements occur. In the event the client fails to satisfy its obligations, the Company has the authority to liquidate certain positions in the client's account(s) at prevailing market prices in order to fulfill the client's obligations. However, during periods of rapid market movements, clients who utilize margin credit or leverage and who have collateralized their obligations with securities may find that the securities have a rapidly depreciating value (or increasing value with respect to short positions) and may not be sufficient to cover their obligations in the event of liquidation. The Company seeks to mitigate the risks associated with its client margin and leverage activities by requiring clients to maintain margin collateral in compliance with various regulatory and internal guidelines. The Company monitors required margin levels throughout each trading day and, pursuant to such guidelines, requires clients to deposit additional collateral, or to reduce positions, when necessary.

The Company contracts with unaffiliated FCM, FDM and broker-dealer entities to clear and execute futures, options on futures and foreign exchange transactions for its clients. This can result in concentrations of credit risk with one or more of these counterparties. This risk is partially mitigated by the counterparties' obligation to comply with rules and regulations governing FCMs, FDMs and broker-dealers in the United States. These rules generally require maintenance of net capital and segregation of client funds and securities. In addition, the Company manages this risk by requiring credit approvals for counterparties and by utilizing account funding and sweep arrangement agreements that generally specify that all client cash in excess of futures funding requirements be transferred back to the clients' securities brokerage accounts at the Company on a daily basis.

The Company loans securities temporarily to other broker-dealers in connection with its broker-dealer business. The Company receives cash as collateral for the securities loaned. Increases in securities prices may cause the market value of the securities loaned to exceed the amount of cash received as collateral. In the event the counterparty to these transactions does not return the loaned securities, the Company may be exposed to the risk of acquiring the securities at higher prevailing market prices in order to satisfy its client obligations. The Company mitigates this risk by requiring credit approvals for counterparties, by monitoring the market value of securities loaned on a daily basis and requiring additional cash as collateral when necessary, and by participating in a risk-sharing program offered through the Options Clearing Corporation ("OCC").

The Company borrows securities temporarily from other broker-dealers in connection with its broker-dealer business. The Company deposits cash as collateral for the securities borrowed. Decreases in securities prices may cause the market value of the securities borrowed to fall below the amount of cash deposited as collateral. In the event the counterparty to these transactions does not return the cash deposited, the Company may be exposed to the risk of selling the securities at lower prevailing market prices. The Company mitigates this risk by requiring credit approvals for counterparties, by monitoring the collateral values on

a daily basis and requiring collateral to be returned by the counterparties when necessary, and by participating in a risk-sharing program offered through the OCC.

The Company transacts in reverse repurchase agreements (securities purchased under agreements to resell) in connection with its broker-dealer business. The Company's policy is to take possession or control of securities with a market value in excess of the principal amount loaned, plus accrued interest, in order to collateralize resale agreements. The Company monitors the market value of the underlying securities that collateralize the related receivable on resale agreements on a daily basis and may require additional collateral when deemed appropriate.

The Company utilizes securities sold under agreements to repurchase (repurchase agreements) to finance its short-term liquidity and capital needs. Under these agreements, the Company receives cash from the counterparties and provides U.S. Treasury securities as collateral, allowing the counterparties the right to sell or repledge the collateral. These agreements expose the Company to credit losses in the event the counterparties cannot meet their obligations. The Company mitigates this risk by requiring credit approvals for counterparties, by monitoring the market value of pledged securities owned on a daily basis and requiring the counterparties to return cash or excess collateral pledged when necessary.

The Company has accepted collateral in connection with client margin loans and securities borrowed. Under applicable agreements, the Company is generally permitted to repledge securities held as collateral and use them to enter into securities lending arrangements. The following table summarizes the fair values of client margin securities and stock borrowings that were available to the Company to utilize as collateral on various borrowings or for other purposes, and the amount of that collateral loaned or repledged by the Company (dollars in billions):

	March 31, 2020		September 30, 2019
Client margin securities	$	22.1	$	28.6
Stock borrowings	0.3		1.9
Total collateral available	$	22.4	$	30.5
Collateral loaned	$	1.6	$	3.2
Collateral repledged	7.7		4.6
Total collateral loaned or repledged	$	9.3	$	7.8

The Company is subject to cash deposit and collateral requirements with clearinghouses based on its clients' trading activity. The following table summarizes cash deposited with and securities pledged to clearinghouses by the Company (dollars in millions):

Assets	Condensed Consolidated Balance Sheet Classification	March 31, 2020		September 30, 2019
Cash	Receivable from brokers, dealers and clearing organizations	$	1,158	$	545
U.S. government debt securities	Securities owned, at fair value	181		168
Total		$	1,339	$	713

The Company manages its sweep program through off-balance sheet arrangements with TD and unaffiliated third-party depository financial institutions (together, the "Sweep Program Counterparties"). The sweep program is offered to eligible clients whereby the client's uninvested cash is swept into FDIC-insured (up to specified limits) money market deposit accounts at the Sweep Program Counterparties. The Company earns revenue on client cash at the Sweep Program Counterparties based on the return of floating-rate and fixed-rate notional investments. The Company designates amounts and maturity dates for the fixed-rate notional investments within the sweep program portfolios, subject to certain limitations. In the event the Company instructs the Sweep Program Counterparties to withdraw a fixed-rate notional investment prior to its maturity, the Company may be required to reimburse the Sweep Program Counterparties for any losses incurred as a result of the early withdrawal. In order to mitigate the risk of potential loss due to an early withdrawal of fixed-rate notional investments, the Company maintains a certain level of short-term floating-rate investments within the sweep program portfolios to meet client cash demands. See "Insured Deposit Account Agreement" in Note 15 for a description of the sweep arrangement between the Company and TD.

Guarantees

The Company is a member of and provides guarantees to securities clearinghouses and exchanges in connection with client trading activities. Under related agreements, the Company is generally required to guarantee the performance of other members. Under these agreements, if a member becomes unable to satisfy its obligations to the clearinghouse, other members would be required to meet shortfalls. The Company's liability under these arrangements is not quantifiable and could exceed the cash and securities it has posted to the clearinghouse as collateral. However, the likelihood that the Company would be required to make payments under these agreements is considered remote. Accordingly, no contingent liability is carried on the Condensed Consolidated Balance Sheets for these guarantees.

The Company clears its clients' futures and options on futures transactions on an omnibus account basis through unaffiliated FCMs. The Company also contracts with an external provider to facilitate foreign exchange trading for its clients. The Company has agreed to indemnify these unaffiliated FCMs and the external provider for any loss that they may incur from the client transactions introduced to them by the Company.

See "Insured Deposit Account Agreement" in Note 15 for a description of the guarantees included in that agreement.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation, Organization and Recent Accounting Pronouncements

Basis of Presentation, Organization and Recent Accounting Pronouncements

Basis of Presentation

The condensed consolidated financial statements include the accounts of TD Ameritrade Holding Corporation (the "Parent") and its wholly-owned subsidiaries (collectively, the "Company"). Intercompany balances and transactions have been eliminated.

These financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and, in the opinion of management, reflect all adjustments, which are all of a normal recurring nature, necessary to present fairly the financial position, results of operations and cash flows for the periods presented in conformity with U.S. generally accepted accounting principles ("GAAP"). These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's annual report filed on Form 10-K for the fiscal year ended September 30, 2019.

Organization

The Company provides securities brokerage services, including trade execution, clearing services and margin lending, through its broker-dealer subsidiaries; futures and foreign exchange trade execution services through its futures commission merchant ("FCM") and forex dealer member ("FDM") subsidiary; and bundled retirement plan solutions to plan sponsors and their advisors through its state-chartered trust company subsidiary. The Company also provides cash sweep and deposit account products through third-party relationships, including relationships with affiliates.

In March 2020, the World Health Organization declared the spread of the coronavirus ("COVID-19") a worldwide pandemic. The pandemic has negatively impacted the global economy and is affecting financial markets, causing significant market volatility and erosion of market value. The Company is actively monitoring the impact of COVID-19 on its business, financial condition, liquidity, operations, employees, clients and business partners. In response to the pandemic and for the protection of the Company's employees, clients and business partners, the Company has implemented remote work arrangements for nearly 100% of its employees, has restricted business travel and has temporarily closed its retail branches. To date, with the Company's ability to meet a vast majority of its clients' needs through its technology-based platforms and services, these arrangements have not materially affected the Company's ability to maintain its business operations, including the operation of financial reporting systems, internal control over financial reporting, and disclosure controls and procedures. Based on information available as of the date of this report, the Company does not expect the pandemic to have a material adverse impact to its results of operations and cash flows in the near term; although, given the daily evolution of the pandemic and the global responses to curb its spread, the Company is currently unable to estimate the long-term effects of the pandemic on its financial condition, results of operations or cash flows.

On November 24, 2019, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with The Charles Schwab Corporation ("Schwab") and Americano Acquisition Corp., a wholly-owned subsidiary of Schwab. The Merger Agreement was included as Exhibit 2.1 to the Company's Form 8-K filed with the SEC on November 27, 2019. Upon the terms and subject to the conditions of the Merger Agreement, Americano Acquisition Corp. will merge with and into the Company (the "Merger"), with the Company surviving as a wholly-owned subsidiary of Schwab. Pursuant to and subject to the terms of the Merger Agreement, at the effective time of the Merger, each share of the Company's common stock, $0.01 par value, issued and outstanding immediately prior to the effective time of the Merger (other than treasury shares held by the Company and certain shares held by Schwab), will be converted into the right to receive 1.0837 shares of Schwab's voting common stock, $0.01 par value (the "Merger Consideration"); however, if the Merger Consideration issuable in respect of shares of the Company's common stock owned by The Toronto-Dominion Bank ("TD") and its affiliates as of immediately prior to the effective time of the Merger, together with any other shares of Schwab common stock then owned by TD and its affiliates, would equal a number of shares of Schwab common stock exceeding 9.9% (or such lower percentage of shares of Schwab common stock as the Federal Reserve Board permits TD to acquire in the Merger consistent with a determination that TD does not control Schwab for purposes of the Bank Holding Company Act of 1956, as amended, or the Home Owners' Loan Act of 1933, as amended) of the issued and outstanding shares of Schwab common stock as of immediately following the effective time of the Merger, then TD will receive one share of nonvoting common stock of Schwab in lieu of each such excess share of Schwab common stock. Completion of the Merger is subject to certain conditions, including obtaining the necessary approvals from stockholders of both the Company and Schwab, the satisfaction of certain regulatory approvals and other customary closing conditions. The parties expect the transaction to close during the second half of calendar year 2020.

For the three and six months ended March 31, 2020, the Company incurred $8 million and $34 million, respectively, of costs related to the proposed Merger, which are included in professional services on the Condensed Consolidated Statements of Income.

Recently Adopted Accounting Pronouncements

ASU 2016-02 — On October 1, 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, Leases, by applying the standard at the adoption date, recognizing a cumulative-effect adjustment to the opening balance of retained earnings. As a result, restated financial information and the additional disclosures required under the new standard will not be provided for the comparative periods presented. The new guidance requires quantitative and qualitative disclosures that provide information about the amounts related to leasing arrangements recorded in the condensed consolidated financial statements. The Company elected a package of practical expedients available under the new guidance, which allows an entity to not reassess prior conclusions related to existing contracts containing leases, lease classification and initial direct costs. In addition, the Company has elected to apply the short-term lease exception for lease arrangements with a maximum term of 12 months or less. Upon the adoption of the lease standard, the Company recognized a right-of-use ("ROU") asset and a lease liability on the Condensed Consolidated Balance Sheet related to non-cancelable operating leases.

The cumulative effect of the changes made to the Company's Condensed Consolidated Balance Sheet as of October 1, 2019 for the adoption of ASU 2016-02 were as follows (dollars in millions):

	Balance at September 30, 2019		Adjustments from Adoption of ASU 2016-02					Balance at October 1, 2019
Assets:
Other assets	$	308	$	341		(1	)	$	649
Liabilities:
Accounts payable and other liabilities	884		342			(2	)	1,226
Stockholders' Equity:
Retained earnings	8,580		(1		)	(3	)	8,579

(1) Adjustments include the following: (a) an increase of $347 million for the recognition of the ROU asset and (b) a decrease of $6 million for lease payments made to lessors at or before the commencement date, which were reclassified to the ROU lease liability upon the adoption of the lease standard.

(2) Adjustments include the following: (a) an increase of $379 million for the recognition of the ROU lease liability and (b) decreases of $30 million for deferred rent and $7 million related to the early termination of lease obligations, which were reclassified to the ROU asset upon the adoption of the lease standard.

(3) Represents the impact of a lease obligation which had no future benefit upon the adoption of the lease standard.

The adoption of this standard did not have a material impact on the Company's results of operations or cash flows. See Note 6 for additional information regarding the Company's operating leases.

Recently Issued Accounting Pronouncements

ASU 2020-04 — In March 2020, the Financial Accounting Standards Board ("FASB") issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting if certain criteria are met. The amendments in ASU 2020-04 provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. This guidance is effective immediately and the amendments may be applied prospectively through December 31, 2022. The Company is evaluating the guidance and the potential impact of adopting ASU 2020-04 on its condensed consolidated financial statements.

ASU 2019-12 — In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The amendments in ASU 2019-12 simplify the accounting for income taxes by removing certain exceptions to the general principles in Accounting Standards Codification ("ASC") Topic 740, Income Taxes. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. ASU 2019-12 will be effective for the Company's fiscal year beginning October 1, 2021, with early adoption permitted. The transition requirements are dependent upon each amendment within this update and will be applied either prospectively or retrospectively. The Company does not expect this ASU to have a material impact on its condensed consolidated financial statements.

ASU 2016-13 — In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments. The main objective of ASU 2016-13 is to provide financial statement users with more decision-useful information about an entity's

expected credit losses on financial instruments and other commitments to extend credit at each reporting date. To achieve this objective, the amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to develop credit loss estimates. Subsequent to issuing ASU 2016-13, the FASB has issued additional standards for the purpose of clarifying certain aspects of ASU 2016-13, as well as providing codification improvements and targeted transition relief under the standard. The subsequently issued ASUs have the same effective date and transition requirements as ASU 2016-13. ASU 2016-13 will be effective for the Company's fiscal year beginning October 1, 2020, using a modified retrospective approach. Early adoption is permitted. The Company is currently assessing the impact this ASU will have on its condensed consolidated financial statements.

Capital Requirements

The Company's broker-dealer subsidiaries are subject to the SEC Uniform Net Capital Rule (Rule 15c3-1 under the Exchange Act), administered by the SEC and the Financial Industry Regulatory Authority, which requires the maintenance of minimum net

capital, as defined. Net capital and the related net capital requirements may fluctuate on a daily basis. TDAC, the Company's clearing broker-dealer subsidiary, and TD Ameritrade, Inc., an introducing broker-dealer subsidiary of the Company, compute net capital under the alternative method as permitted by SEC Rule 15c3-1. TDAC is required to maintain minimum net capital of the greater of $1.5 million, which is based on the type of business conducted by the broker-dealer, or 2% of aggregate debit balances arising from client transactions. TD Ameritrade, Inc. is required to maintain minimum net capital of the greater of $250,000 or 2% of aggregate debit balances arising from client transactions. In addition, under the alternative method, a broker-dealer may not repay any subordinated borrowings, pay cash dividends or make any unsecured advances or loans to its parent company or employees if such payment would result in net capital of less than (1) 5% of aggregate debit balances or (2) 120% of its minimum dollar requirement.

TD Ameritrade Futures & Forex LLC ("TDAFF"), the Company's FCM and FDM subsidiary registered with the CFTC, is subject to CFTC Regulations 1.17 and 5.7 under the Commodity Exchange Act, administered by the CFTC and the National Futures Association. As an FCM, TDAFF is required to maintain minimum adjusted net capital under CFTC Regulation 1.17 of the greater of (1) $1.0 million or (2) its futures risk-based capital requirement, equal to 8% of the total risk margin requirement for all futures and options on futures positions carried by the FCM in client and nonclient accounts. As an FDM, TDAFF is also subject to the net capital requirements under CFTC Regulation 5.7, which requires TDAFF to maintain minimum adjusted net capital of the greater of (1) any amount required under CFTC Regulation 1.17 as described above or (2) $20.0 million plus 5% of all foreign exchange liabilities owed to forex clients in excess of $10.0 million. In addition, an FCM and FDM must provide notice to the CFTC if its adjusted net capital amounts to less than (1) 110% of its risk-based capital requirement under CFTC Regulation 1.17, (2) 150% of its $1.0 million minimum dollar requirement or (3) 110% of $20.0 million plus 5% of all foreign exchange liabilities owed to forex clients in excess of $10.0 million.

Subsequent Events [Abstract]

Subsequent Event

Subsequent Event

On April 21, 2020, TDAC entered into an amendment to the $850 million Revolving Credit Facility, which provides for a senior unsecured revolving credit facility in the aggregate principal amount of $850 million that matures on April 20, 2021 (the "Amended Credit Agreement"). Borrowings under the Amended Credit Agreement may be used for working capital needs and for general corporate purposes.

The applicable interest rate under the Amended Credit Agreement is calculated as a per annum rate equal to, at the option of TDAC, (1) LIBOR plus an interest rate margin ("Amended Eurodollar loans") or (2) the federal funds effective rate plus an interest rate margin ("Amended Federal Funds Rate loans"). The interest rate margin will range from 1.00% to 1.50% for both Amended Eurodollar loans and Amended Federal Funds Rate loans, determined by reference to the Company's public debt ratings. TDAC will be obligated to pay a commitment fee ranging from 0.20% to 0.35% on any unused amount of the Amended Credit Agreement, determined by reference to the Company's public debt ratings.

The Amended Credit Agreement contains negative covenants that limit or restrict, subject to certain exceptions, the incurrence of liens, indebtedness of TDAC, changes in nature of business, mergers, consolidations, and the sale of all or substantially all of the assets of TDAC. TDAC is also required to maintain minimum consolidated tangible net worth and is required to maintain compliance with minimum regulatory net capital requirements. The Amended Credit Agreement also contains customary affirmative covenants, including, but not limited to, compliance with applicable law, payment of taxes, maintenance of insurance, preservation of corporate existence, keeping of proper books of record and account and maintenance of properties.
