Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis Of Presentation	BASIS OF PRESENTATION Realogy Holdings Corp. ("Realogy Holdings", "Realogy" or the "Company") is a holding company for its consolidated subsidiaries including Realogy Intermediate Holdings LLC ("Realogy Intermediate") and Realogy Group LLC ("Realogy Group") and its consolidated subsidiaries. Realogy, through its subsidiaries, is a global provider of residential real estate services. Neither Realogy Holdings, the indirect parent of Realogy Group, nor Realogy Intermediate, the direct parent company of Realogy Group, conducts any operations other than with respect to its respective direct or indirect ownership of Realogy Group. As a result, the consolidated financial positions, results of operations, comprehensive income (loss) and cash flows of Realogy Holdings, Realogy Intermediate and Realogy Group are the same. The accompanying Condensed Consolidated Financial Statements include the financial statements of Realogy Holdings and Realogy Group. Realogy Holdings' only asset is its investment in the common stock of Realogy Intermediate, and Realogy Intermediate's only asset is its investment in Realogy Group. Realogy Holdings' only obligations are its guarantees of certain borrowings and certain franchise obligations of Realogy Group. All expenses incurred by Realogy Holdings and Realogy Intermediate are for the benefit of Realogy Group and have been reflected in Realogy Group's Condensed Consolidated Financial Statements. The Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America and with Article 10 of Regulation S-X. Interim results may not be indicative of full year performance because of seasonal and short-term variations. The Company has eliminated all material intercompany transactions and balances between entities consolidated in these financial statements. In presenting the Condensed Consolidated Financial Statements, management makes estimates and assumptions that affect the amounts reported and the related disclosures. Estimates, by their nature, are based on judgment and available information. Accordingly, actual results could differ materially from those estimates. In management's opinion, the accompanying unaudited Condensed Consolidated Financial Statements reflect all normal and recurring adjustments necessary for a fair statement of Realogy Holdings and Realogy Group's financial position as of September 30, 2021 and the results of operations and comprehensive income (loss) for the three and nine months ended September 30, 2021 and 2020 and cash flows for the nine months ended September 30, 2021 and 2020. The Consolidated Balance Sheet at December 31, 2020 was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. The Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2020. Fair Value Measurements The following tables present the Company’s assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level Input: Input Definitions: Level I Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets at the measurement date. Level II Inputs other than quoted prices included in Level I that are observable for the asset or liability through corroboration with market data at the measurement date. Level III Unobservable inputs that reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The availability of observable inputs can vary from asset to asset and is affected by a wide variety of factors, including, for example, the type of asset, whether the asset is new and not yet established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level III. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value of financial instruments is generally determined by reference to quoted market values. In cases where quoted market prices are not available, fair value is based on estimates using present value or other valuation techniques, as appropriate. The fair value of interest rate swaps is determined based upon a discounted cash flow approach. The Company measures financial instruments at fair value on a recurring basis and recognizes transfers within the fair value hierarchy at the end of the fiscal quarter in which the change in circumstances that caused the transfer occurred. The following table summarizes fair value measurements by level at September 30, 2021 for assets and liabilities measured at fair value on a recurring basis: Level I Level II Level III Total Deferred compensation plan assets (included in other non-current assets) $ 1 $ — $ — $ 1 Interest rate swaps (included in other non-current liabilities) — 57 — 57 Contingent consideration for acquisitions (included in accrued expenses and other current liabilities and other non-current liabilities) — — 3 3 The following table summarizes fair value measurements by level at December 31, 2020 for assets and liabilities measured at fair value on a recurring basis: Level I Level II Level III Total Deferred compensation plan assets (included in other non-current assets) $ 1 $ — $ — $ 1 Interest rate swaps (included in other non-current liabilities) — 81 — 81 Contingent consideration for acquisitions (included in accrued expenses and other current liabilities and other non-current liabilities) — — 3 3 The fair value of the Company’s contingent consideration for acquisitions is measured using a probability weighted-average discount rate to estimate future cash flows based upon the likelihood of achieving future operating results for individual acquisitions. These assumptions are deemed to be unobservable inputs and as such the Company’s contingent consideration is classified within Level III of the valuation hierarchy. The Company reassesses the fair value of the contingent consideration liabilities on a quarterly basis. The following table presents changes in Level III financial liabilities measured at fair value on a recurring basis: Level III Fair value of contingent consideration at December 31, 2020 $ 3 Additions: contingent consideration related to acquisitions completed during the period 1 Reductions: payments of contingent consideration (1) Changes in fair value (reflected in general and administrative expenses) — Fair value of contingent consideration at September 30, 2021 $ 3 The following table summarizes the principal amount of the Company’s indebtedness compared to the estimated fair value, primarily determined by quoted market values, at: September 30, 2021 December 31, 2020 Debt Principal Amount Estimated Principal Amount Estimated Senior Secured Credit Facility: Non-extended Revolving Credit Commitment $ — $ — $ — $ — Extended Revolving Credit Commitment — — — — Term Loan B — — 1,048 1,032 Term Loan A Facility: Non-extended Term Loan A — — 684 671 Extended Term Loan A 234 230 — — 7.625% Senior Secured Second Lien Notes 550 586 550 595 4.875% Senior Notes 407 422 407 415 9.375% Senior Notes 550 604 550 609 5.75% Senior Notes 900 932 — — 0.25% Exchangeable Senior Notes 403 406 — — _______________ (a) The fair value of the Company's indebtedness is categorized as Level II.

The Company's investment in Guaranteed Rate Affinity, LLC ("Guaranteed Rate Affinity") at Realogy Title Group had investment balances of $94 million and $90 million at September 30, 2021 and December 31, 2020, respectively.

The provision for income taxes was an expense of $48 million and $36 million for the three months ended September 30, 2021 and 2020, respectively, and an expense of $125 million and a benefit of $110 million for the nine months ended September 30, 2021 and 2020, respectively. Derivative Instruments The Company records derivatives and hedging activities on the balance sheet at their respective fair values. The Company enters into interest rate swaps to manage its exposure to changes in interest rates associated with its variable rate borrowings. As of September 30, 2021, the Company had interest rate swaps with an aggregate notional value of $1,000 million to offset the variability in cash flows resulting from the term loan facilities as follows: Notional Value (in millions) Commencement Date Expiration Date $450 November 2017 November 2022 $400 August 2020 August 2025 $150 November 2022 November 2027 The swaps help to protect our outstanding variable rate borrowings from future interest rate volatility. The Company has not elected to utilize hedge accounting for these interest rate swaps; therefore, any change in fair value is recorded in the Condensed Consolidated Statements of Operations. The fair value of derivative instruments was as follows: Not Designated as Hedging Instruments Balance Sheet Location September 30, 2021 December 31, 2020 Interest rate swap contracts Other non-current liabilities 57 81 The effect of derivative instruments on earnings was as follows: Derivative Instruments Not Designated as Hedging Instruments Location of Loss or (Gain) Recognized for Derivative Instruments Loss or (Gain) Recognized on Derivatives Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Interest rate swap contracts Interest expense $ (1) $ — $ (8) $ 59 Revenue Revenue is recognized upon the transfer of control of promised services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those services in accordance with the revenue standard.

(b) Service revenue primarily consists of title and escrow fees at Realogy Title Group and are recognized at a point in time at the closing of a homesale transaction. Service revenue at Realogy Franchise Group includes relocation fees, which are recognized as revenue when or as the related performance obligation is satisfied dependent on the type of service performed, and fees related to leads and related services, which are recognized at a point in time at the closing of a homesale transaction or at the completion of the related service. (c) Franchise fees at Realogy Franchise Group primarily include domestic royalties which are recognized at a point in time when the underlying franchisee revenue is earned (upon close of the homesale transaction). (d) Other revenue is comprised of brand marketing funds received from franchisees at Realogy Franchise Group and other miscellaneous revenues across all of the business segments. The following table shows the change in the Company's contract liabilities (deferred revenue) related to revenue contracts by reportable segment for the period: Beginning Balance at January 1, 2021 Additions during the period Recognized as Revenue during the period Ending Balance at September 30, 2021 Realogy Franchise Group: Deferred area development fees (a) $ 43 $ 1 $ (4) $ 40 Deferred brand marketing fund fees (b) 14 78 (71) 21 Deferred outsourcing management fees (c) 3 31 (30) 4 Other deferred income related to revenue contracts 10 24 (23) 11 Total Realogy Franchise Group 70 134 (128) 76 Realogy Brokerage Group: Advanced commissions related to development business (d) 9 2 — 11 Other deferred income related to revenue contracts 3 2 (2) 3 Total Realogy Brokerage Group 12 4 (2) 14 Total $ 82 $ 138 $ (130) $ 90 _______________ (a) The Company collects initial area development fees ("ADF") for international territory transactions, which are recorded as deferred revenue when received and recognized into franchise revenue over the average 25 year life of the related franchise agreement as consideration for the right to access and benefit from Realogy’s brands. In the event an ADF agreement is terminated prior to the end of its term, the unamortized deferred revenue balance will be recognized into revenue immediately upon termination. (b) Revenues recognized include intercompany marketing fees paid by Realogy Brokerage Group. (c) The Company earns revenues from outsourcing management fees charged to clients that may cover several of the relocation services listed above, according to the clients' specific needs. Outsourcing management fees are recorded as deferred revenue when billed (usually at the start of the relocation) and are recognized as revenue over the average time period required to complete the transferee's move, or a phase of the move that the fee covers, which is typically 3 to 6 months depending on the move type. (d) New development closings generally have a development period of between 18 and 24 months from contracted date to closing. Allowance for Doubtful Accounts The Company estimates the allowance necessary to provide for uncollectible accounts receivable. The estimate is based on historical experience, combined with a review of current conditions and forecasts of future losses, and includes specific accounts for which payment has become unlikely. The process by which the Company calculates the allowance begins in the individual business units where specific problem accounts are identified and reserved primarily based upon the age profile of the receivables and specific payment issues, combined with reasonable and supportable forecasts of future losses. Supplemental Cash Flow Information Significant non-cash transactions included finance lease additions of $4 million and $9 million during the nine months ended September 30, 2021 and 2020, respectively, which resulted in non-cash additions to property and equipment, net and other non-current liabilities. Leases Other than the Company's facility closures as described in Note 5, "Restructuring Costs," the Company's lease obligations as of September 30, 2021 have not changed materially from the amounts reported in our 2020 Form 10-K. Recently Adopted Accounting Pronouncements The Company adopted the new standard on Simplifying the Accounting for Income Taxes effective January 1, 2021. The new standard clarifies and simplifies aspects of the accounting for income taxes to help promote consistent application of GAAP by eliminating certain exceptions to the general principles of ASC Topic 740, Income Taxes. The adoption of this guidance did not have an impact to the Company’s Consolidated Financial Statements upon adoption on January 1, 2021. Recently Issued Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates ("ASUs"). Recently issued standards were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations. The FASB issued its new standard on Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity which simplifies the accounting for instruments with characteristics of liabilities and equity, including convertible debt. The new standard reduces the number of accounting models for convertible debt instruments and convertible preferred stock resulting in fewer embedded conversion features being separately recognized from the host contract and the interest rate of more convertible debt instruments being closer to the coupon interest rate, as compared with current guidance. The new standard also amends the derivative guidance for the “own stock” scope exception, which exempts qualifying instruments from being accounted for as derivatives if certain criteria are met. In addition, the standard changes the diluted earnings per share calculation for instruments that may be settled in cash or shares and for convertible instruments. The new standard is effective for reporting periods beginning on or after December 15, 2021 and permits the use of either the modified retrospective or fully retrospective method of transition. The Company plans to adopt the new standard on January 1, 2022 using the modified retrospective approach and is currently evaluating the impact of adopting this standard on the Company's financial statements.

The Non-extended Revolving Credit Commitment expires in February 2023 and, subject to earlier springing maturity described in footnote (3), the Extended Revolving Credit Commitment expires in February 2025, but in each instance, amounts outstanding would be classified on the balance sheet as current due to the revolving nature and terms and conditions of the facilities. On November 1, 2021, the Company had no outstanding borrowings under the Revolving Credit Facility and $42 million of outstanding undrawn letters of credit. (2) Interest rates with respect to revolving loans under the Senior Secured Credit Facility at September 30, 2021 are based on, at the Company's option, (a) adjusted London Interbank Offering Rate ("LIBOR") plus an additional margin or (b) JP Morgan Chase Bank, N.A.'s prime rate ("ABR") plus an additional margin, in each case subject to adjustment based on the then current senior secured leverage ratio.

The current portion of long-term debt of $9 million shown on the Condensed Consolidated Balance Sheets consists of four quarters of amortization payments for the Extended Term Loan A. Senior Secured Credit Agreement and Term Loan A Agreement The Company's Amended and Restated Credit Agreement dated as of March 5, 2013 (as amended, amended and restated, modified or supplemented from time to time, the "Senior Secured Credit Agreement") governs its senior secured revolving credit facility (the "Revolving Credit Facility") and, until its repayment in full in September 2021, term loan B facility (the "Term Loan B Facility", and collectively with the Revolving Credit Facility, the "Senior Secured Credit Facility") and the Company's Term Loan A Agreement dated as of October 23, 2015 (as amended, amended and restated, modified or supplemented from time to time, the "Term Loan A Agreement") governs its senior secured term loan A credit facility (the "Term Loan A Facility"). In the first quarter of 2021, the Company repaid $250 million of outstanding borrowings under the Term Loan A Facility and $655 million of outstanding borrowings under the Term Loan B Facility using proceeds from its January and February 2021 issuances of $900 million 5.75% Senior Notes due 2029. In April 2021, the Company used cash on hand to pay down $150 million of outstanding borrowings under the Term Loan B Facility. In September 2021, the Company used cash on hand to repay approximately $197 million in principal amount of outstanding borrowings under the Term Loan A Facility (representing all of the remaining Non-Extended Term Loan A) and approximately $238 million in principal amount of outstanding borrowings under the Term Loan B Facility (representing all of the remaining Term Loan B). In January 2021, Realogy Group entered into amendments to the Senior Secured Credit Agreement, referred to collectively herein as the "2021 Amendments", which among other things extended the maturity of a portion of the outstanding loans under the Term Loan A Facility (the "Extended Term Loan A") and a portion of the commitments under the Revolving Credit Facility (the "Extended Revolving Credit Commitment"), in each case from February 2023 to February 2025, provided that if on or before March 2, 2023, the 4.875% Senior Notes have not been extended, refinanced or replaced to have a maturity date after May 10, 2025 (or are not otherwise discharged, defeased or repaid by March 2, 2023), the maturity date of the Extended Term Loan A and Extended Revolving Credit Commitment will be March 2, 2023. Senior Secured Credit Facility The Senior Secured Credit Facility includes a $1,425 million Revolving Credit Facility which includes a $125 million letter of credit subfacility. The Revolving Credit Facility includes available capacity under the Non-extended Revolving Credit Commitment of $477 million and the available capacity under the Extended Revolving Credit Commitment of $948 million. The Non-extended Revolving Credit Commitment expires in February 2023 and, subject to earlier springing maturity described above, the Extended Revolving Credit Commitment expires in February 2025. The interest rate with respect to revolving loans under the Revolving Credit Facility is based on, at Realogy Group's option, adjusted LIBOR or ABR plus an additional margin subject to the following adjustments based on the Company’s then current senior secured leverage ratio: Senior Secured Leverage Ratio Applicable LIBOR Margin Applicable ABR Margin Greater than 3.50 to 1.00 2.50% 1.50% Less than or equal to 3.50 to 1.00 but greater than or equal to 2.50 to 1.00 2.25% 1.25% Less than 2.50 to 1.00 but greater than or equal to 2.00 to 1.00 2.00% 1.00% Less than 2.00 to 1.00 1.75% 0.75% Until its repayment in full in September 2021, the Senior Secured Credit Facility also included the Term Loan B Facility issued in the original aggregate principal amount of $1,080 million with a maturity date of February 2025. The Term Loan B Facility had quarterly amortization payments totaling 1% per annum of the initial aggregate principal amount. The interest rate with respect to term loans under the Term Loan B Facility was based on, at Realogy Group's option, adjusted LIBOR plus 2.25% (with a LIBOR floor of 0.75%) or ABR plus 1.25% (with an ABR floor of 1.75%). The obligations under the Senior Secured Credit Agreement are secured to the extent legally permissible by substantially all of the assets of Realogy Group, Realogy Intermediate and all of their domestic subsidiaries, other than certain excluded subsidiaries and subject to certain exceptions. Realogy Group's Senior Secured Credit Agreement contains financial, affirmative and negative covenants as well as a financial covenant that Realogy Group maintain (so long as commitments under the Revolving Credit Facility are outstanding) a maximum permitted senior secured leverage ratio, not to exceed 4.75 to 1.00. The leverage ratio is tested quarterly regardless of the amount of borrowings outstanding and letters of credit issued under the Revolving Credit Facility at the testing date. Total senior secured net debt does not include the securitization obligations, 7.625% Senior Secured Second Lien Notes, or our unsecured indebtedness, including the Unsecured Notes and the Exchangeable Senior Notes. At September 30, 2021, Realogy Group was in compliance with the senior secured leverage ratio covenant. For the calculation of the senior secured leverage ratio for the third quarter of 2021, see Part I., "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations—Senior Secured Leverage Ratio applicable to our Senior Secured Credit Facility and Term Loan A Facility". Term Loan A Facility The term loans under the Term Loan A Facility were originally $750 million. In September 2021, the Company repaid the Non-extended Term Loan A due February 2023 in full. The Extended Term Loan A due February 2025, subject to earlier springing maturity described above, provides for quarterly amortization based on a percentage of the principal amount of $237 million, which commenced on June 30, 2021, as follows: 0.625% per quarter from June 30, 2021 to March 31, 2022; 1.25% per quarter from June 30, 2022 to March 31, 2023; 1.875% per quarter from June 30, 2023 to March 31, 2024; and 2.50% per quarter for periods ending on or after June 30, 2024, with the balance of the Extended Term Loan A due at maturity on February 8, 2025. No amortization payments were required on the Non-extended Term Loan A. The interest rates with respect to the Term Loan A Facility are based on, at the Company's option, adjusted LIBOR or ABR plus an additional margin subject to the following adjustments based on the Company's then current senior secured leverage ratio: Senior Secured Leverage Ratio Applicable LIBOR Margin Applicable ABR Margin Greater than 3.50 to 1.00 2.50% 1.50% Less than or equal to 3.50 to 1.00 but greater than or equal to 2.50 to 1.00 2.25% 1.25% Less than 2.50 to 1.00 but greater than or equal to 2.00 to 1.00 2.00% 1.00% Less than 2.00 to 1.00 1.75% 0.75% The Term Loan A Agreement contains covenants that are substantially similar to those in the Senior Secured Credit Agreement. Senior Secured Second Lien Notes The 7.625% Senior Secured Second Lien Notes mature on June 15, 2025 and interest is payable semiannually on June 15 and December 15 of each year. The 7.625% Senior Secured Second Lien Notes are guaranteed on a senior secured second priority basis by Realogy Intermediate and each domestic subsidiary of Realogy Group, other than certain excluded entities, that is a guarantor under its Senior Secured Credit Facility and Term Loan A Facility and certain of its outstanding debt securities. The 7.625% Senior Secured Second Lien Notes are also guaranteed by Realogy Holdings on an unsecured senior subordinated basis. The 7.625% Senior Secured Second Lien Notes are secured by substantially the same collateral as Realogy Group's existing first lien obligations under its Senior Secured Credit Facility and Term Loan A Facility on a second priority basis. The indentures governing the 7.625% Senior Secured Second Lien Notes contain various covenants that limit the ability of Realogy Intermediate, Realogy Group and Realogy Group's restricted subsidiaries to take certain actions, which covenants are subject to a number of important exceptions and qualifications. These covenants are substantially similar to the covenants in the indenture governing the 9.375% Senior Notes due 2027, as described under Unsecured Notes below. Unsecured Notes The 4.875% Senior Notes, 9.375% Senior Notes and 5.75% Senior Notes (collectively the "Unsecured Notes") are unsecured senior obligations of Realogy Group that mature on June 1, 2023, April 1, 2027 and January 15, 2029, respectively. Interest on the Unsecured Notes is payable each year semiannually on June 1 and December 1 for the 4.875% Senior Notes, on April 1 and October 1 for the 9.375% Senior Notes, and on January 15 and July 15 for the 5.75% Senior Notes (which commenced on July 15, 2021). The Unsecured Notes are guaranteed on an unsecured senior basis by each domestic subsidiary of Realogy Group that is a guarantor under the Senior Secured Credit Facility, Term Loan A Facility and Realogy Group's outstanding debt securities and are guaranteed by Realogy Holdings on an unsecured senior subordinated basis. The indenture governing the 4.875% Senior Notes contains various negative covenants that limit Realogy Group's and its restricted subsidiaries' ability to take certain actions, which covenants are subject to a number of important exceptions and qualifications. These covenants include limitations on Realogy Group's and its restricted subsidiaries’ ability to (a) incur or guarantee additional indebtedness, or issue disqualified stock or preferred stock, (b) pay dividends or make distributions to their stockholders, (c) repurchase or redeem capital stock, (d) make investments or acquisitions, (e) incur restrictions on the ability of certain of their subsidiaries to pay dividends or to make other payments to Realogy Group, (f) enter into transactions with affiliates, (g) create liens, (h) merge or consolidate with other companies or transfer all or substantially all of their assets, (i) transfer or sell assets, including capital stock of subsidiaries and (j) prepay, redeem or repurchase debt that is subordinated in right of payment to the Unsecured Notes. The covenants in the indenture governing the 9.375% Senior Notes are substantially similar to the covenants in the indentures governing the 4.875% Senior Notes, with certain exceptions, including several changes relating to Realogy Group's ability to make restricted payments, and in particular, its ability to repurchase shares and pay dividends. Specifically, with respect to the 9.375% Senior Notes Indenture, (a) neither the cumulative credit basket (nor any other basket) is available to repurchase shares to the extent the consolidated leverage ratio is equal to or greater than 4.0 to 1.0 on a pro forma basis giving effect to such repurchase; (b) the cumulative credit basket for which restricted payments may otherwise be available is equal to 50% of Consolidated Net Income (as defined in such indenture) for the period (taken as one accounting period) from January 1, 2019 to the end of the most recently ended fiscal quarter for which internal financial statements are available at the time of any such restricted payment; provided however, that, to the extent the Consolidated Leverage Ratio is equal to or greater than 4.0 to 1.0, then 25% of the Consolidated Net Income for the aforementioned period will be included; (c) the consolidated leverage ratio must be less than 3.0 to 1.0 to use the unlimited general restricted payment basket (which payments will reduce the cumulative credit basket, but not below zero); (d) the $100 million general restricted payment basket may be used only for Restricted Investments (as defined in such indenture); and (e) a restricted payment basket is available for up to $45 million of dividends per calendar year (with any actual dividends deducted from the available cumulative credit basket). The covenants in the indenture governing 5.75% Senior Notes are substantially similar to the covenants in the indentures governing the 4.875% Senior Notes, but also include some of the additional limitations of the 9.375% Senior Notes. The consolidated leverage ratio is measured by dividing Realogy Group's total net debt by the trailing four quarters EBITDA. EBITDA, as defined in the indenture governing the 9.375% Senior Notes (as well as the other Unsecured Notes and 7.625% Senior Secured Second Lien Notes), is substantially similar to EBITDA calculated on a Pro Forma Basis, as those terms are defined in the Senior Secured Credit Agreement. Net debt under the indentures governing the 9.375% Senior Notes, 7.625% Senior Secured Second Lien Notes and 5.75% Senior Notes is Realogy Group's total indebtedness (excluding securitizations) less (i) its cash and cash equivalents in excess of restricted cash and (ii) a $200 million seasonality adjustment permitted when measuring the ratio on a date during the period of March 1 to May 31. Exchangeable Senior Notes In June 2021, Realogy Group issued an aggregate principal amount of $403 million of 0.25% Exchangeable Senior Notes due 2026. The Company used a portion of the net proceeds from this offering to pay the cost of the exchangeable note hedge transactions described below (with such cost partially offset by the proceeds to the Company from the sale of the warrants pursuant to the warrant transactions described below). The Company expects to use the remaining net proceeds for its working capital and other general corporate purposes. The Exchangeable Senior Notes are unsecured senior obligations of Realogy Group that mature on June 15, 2026. Interest on the Exchangeable Senior Notes is payable each year semiannually on June 15 and December 15 (commencing on December 15, 2021). The Exchangeable Senior Notes are guaranteed on an unsecured senior basis by each domestic subsidiary of Realogy Group that is a guarantor under the Senior Secured Credit Facility, Term Loan A Facility and Realogy Group's outstanding debt securities and are guaranteed by Realogy Holdings on an unsecured senior subordinated basis. Before March 15, 2026, noteholders will have the right to exchange their Exchangeable Senior Notes upon the occurrence of certain events described in the indenture governing the notes. On or after March 15, 2026, noteholders may exchange their Exchangeable Senior Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date of the notes. Upon exchange, Realogy Group will pay cash up to the aggregate principal amount of the Exchangeable Senior Notes to be exchanged and pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at Realogy Group's election, in respect of the remainder, if any, of its exchange obligation in excess of the aggregate principal amount of the Exchangeable Senior Notes being exchanged. The initial exchange rate for Exchangeable Senior Notes is 40.8397 shares of the Company’s common stock per $1,000 principal amount of notes (which represents an initial exchange price of approximately $24.49 per share of the Company’s common stock). The exchange rate and exchange price of the Exchangeable Senior Notes are subject to customary adjustments upon the occurrence of certain events. In addition, if a “Make-Whole Fundamental Change” (as defined in the indenture governing the Exchangeable Senior Notes) occurs, then the exchange rate of the Exchangeable Senior Notes will, in certain circumstances, be increased for a specified period of time. Initially, a maximum of approximately 23,013,139 shares of the Company’s common stock may be issued upon the exchange of the Exchangeable Senior Notes, based on the initial maximum exchange rate of 57.1755 shares of the Company’s common stock per $1,000 principal amount of notes, which is subject to customary anti-dilution adjustment provisions. The Exchangeable Senior Notes will be redeemable, in whole or in part (subject to a partial redemption limitation described in the indenture governing the notes), at Realogy Group's option at any time, and from time to time, on or after June 20, 2024 and on or before the 30th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the Exchangeable Senior Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of the Company’s common stock exceeds 130% of the exchange price on (1) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date it sends the related redemption notice; and (2) the trading day immediately before the date it sends such notice. In addition, calling any Exchangeable Senior Notes for redemption will constitute a Make-Whole Fundamental Change with respect to that note, in which case the exchange rate applicable to the exchange of that note will be increased in certain circumstances if it is exchanged with an exchange date occurring during the period from, and including, the date Realogy Group sends the redemption notice to, and including, the second business day immediately before the related redemption date. If certain corporate events that constitute a “Fundamental Change” (as defined in the indenture governing the Exchangeable Senior Notes) of the Company occur, then noteholders may require Realogy Group to repurchase their Exchangeable Senior Notes at a cash repurchase price equal to the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. The definition of Fundamental Change includes, among other things, certain business combination transactions involving the Company and certain de-listing events with respect to the Company’s common stock. The indenture governing the Exchangeable Senior Notes also provides for events of default which, if any of them occurs, would permit or require the principal of and accrued interest on the Exchangeable Senior Notes to become or to be declared due and payable. Exchangeable debt instruments that may be settled in cash are required to be separated into liability and equity components. The allocation to the liability component is based on the fair value of a similar instrument that does not contain an equity conversion option. Based on this debt to equity ratio, debt issuance costs are then allocated to the liability and equity components in a similar manner. Accordingly, at issuance on June 2, 2021, the Company allocated $319 million to the debt liability and $53 million to additional paid in capital. The difference between the principal amount of the Exchangeable Senior Notes and the liability component, inclusive of issuance costs, represents the debt discount, which the Company will amortize to interest expense over the term of the Exchangeable Senior Notes using an effective interest rate of 4.375%. The Company recognized non-cash interest expense of $4 million related to the Exchangeable Senior Notes since issuance in the second quarter of 2021. The Exchangeable Senior Notes consisted of the following components as of September 30, 2021: September 30, 2021 Liability component: Principal $ 403 Less: debt discount and issuance costs, net of amortization 79 Net carrying amount $ 324 Equity component: (*) $ 53 _______________ (*) Included in additional paid-in capital on the consolidated balance sheets. Exchangeable Note Hedge and Warrant Transactions In connection with the pricing of the Exchangeable Senior Notes (and with the exercise by the initial purchasers of the notes to purchase additional notes), Realogy Group entered into exchangeable note hedge transactions with certain counterparties (the "Option Counterparties"). The exchangeable note hedge transactions cover, subject to anti-dilution adjustments substantially similar to those applicable to the Exchangeable Senior Notes, the number of shares of the Company’s common stock underlying the Notes. The total cost of such exchangeable note hedge transactions was $67 million. Concurrently with Realogy Group entering into the exchangeable note hedge transactions, the Company entered into warrant transactions with the Option Counterparties whereby the Company sold to the Option Counterparties warrants to purchase, subject to customary adjustments, up to the same number of shares of the Company’s common stock. The initial strike price of the warrant transactions is $30.6075 per share. The Company received $46 million in cash proceeds from the sale of these warrant transactions. Taken together, the purchase of such exchangeable note hedges and the sale of such warrants are intended to offset (in whole or in part) any potential dilution and/or cash payments upon the exchange of the Exchangeable Senior Notes, and to effectively increase the overall exchange price from $24.49 to $30.6075 per share. At issuance, the Company recorded a deferred tax liability of $20 million related to the Exchangeable Senior Notes debt discount and a deferred tax asset of $18 million related to the exchangeable note hedge transactions. The deferred tax liability and deferred tax asset are recorded net within deferred income taxes in the unaudited consolidated balance sheets. Securitization Obligations Realogy Group has secured obligations through Apple Ridge Funding LLC under a securitization program which expires in June 2022. As of September 30, 2021, the Company had $200 million of borrowing capacity under the Apple Ridge Funding LLC securitization program with $144 million being utilized, leaving $56 million of available capacity subject to maintaining sufficient relocation related assets to collateralize the securitization obligation. Realogy Group, through a special purpose entity known as Cartus Financing Limited, has agreements providing for a £10 million revolving loan facility and a £5 million working capital facility. In August 2021, Realogy Group extended the existing Cartus Financing Limited securitization program to September 2021 and in September 2021 the program was amended and further extended from October 2021 to September 2022, consisting of a £5 million revolving loan facility and a £5 million working capital facility. As of September 30, 2021, there were $2 million of outstanding borrowings under the facilities leaving $18 million of available capacity subject to maintaining sufficient relocation related assets to collateralize the securitization obligation. These Cartus Financing Limited facilities are secured by the relocation assets of a U.K. government contract in this special purpose entity and are therefore classified as permitted securitization financings as defined in Realogy Group’s Senior Secured Credit Agreement and the indentures governing the Unsecured Notes and 7.625% Senior Secured Second Lien Notes. The Apple Ridge entities and the Cartus Financing Limited entity are consolidated special purpose entities that are utilized to securitize relocation receivables and related assets. These assets are generated from advancing funds on behalf of clients of Realogy Group’s relocation operations in order to facilitate the relocation of their employees. Assets of these special purpose entities are not available to pay Realogy Group’s general obligations. Under the Apple Ridge program, provided no termination or amortization event has occurred, any new receivables generated under the designated relocation management agreements are sold into the securitization pro

Restructuring and Related Activities Disclosure	. RESTRUCTURING COSTS Restructuring charges were $4 million and $14 million for the three and nine months ended September 30, 2021, respectively, and $17 million and $47 million for the three and nine months ended September 30, 2020, respectively. The components of the restructuring charges for the three and nine months ended September 30, 2021 and 2020 were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Personnel-related costs (1) $ 1 $ 5 $ 5 $ 13 Facility-related costs (2) 3 12 9 34 Total restructuring charges $ 4 $ 17 $ 14 $ 47 _______________ (1) Personnel-related costs consist of severance costs provided to employees who have been terminated and duplicate payroll costs during transition. (2) Facility-related costs consist of costs associated with planned facility closures such as contract termination costs, amortization of lease assets that will continue to be incurred under the contract for its remaining term without economic benefit to the Company, accelerated depreciation on asset disposals and other facility and employee relocation related costs. Facility and Operational Efficiencies Program Beginning in the first quarter of 2019, the Company commenced the implementation of a plan to accelerate its office consolidation to reduce storefront costs, as well as institute other operational efficiencies to drive profitability. In addition, the Company commenced a plan to transform and centralize certain aspects of the operational support and drive changes in how it serves its affiliated independent sales agents from a marketing and technology perspective to help such agents be more productive and enable them to make their businesses more profitable. In the third quarter of 2019, the Company reduced headcount in connection with the wind-down of a former affinity real estate benefit program. In the fourth quarter of 2019, the Company expanded its operational efficiencies program to focus on workforce optimization. This workforce optimization initiative was focused on consolidating similar or overlapping roles, reducing the number of hierarchical layers and streamlining work and decision making. Furthermore, at the end of 2019, the Company expanded these strategic initiatives which have resulted in additional operational and facility related efficiencies in 2020. As a result of the COVID-19 pandemic, the Company transitioned substantially all of its employees to a remote-work environment in mid-March 2020 and has worked to comply with state and local regulators to ensure safe working conditions. Many of the Company's employees continued t o work remotely on a full-time or hybrid basis. This transition to remote work has allowed the Company to reevaluate its office space needs. As a result, additional facility and operational efficiencies were identified and implemented in the second half of 2020 and in 2021. The following is a reconciliation of the beginning and ending reserve balances related to the Facility and Operational Efficiencies Program: Personnel-related costs Facility-related costs Total Balance at December 31, 2020 $ 5 $ 22 $ 27 Restructuring charges (1) 5 9 14 Costs paid or otherwise settled (7) (14) (21) Balance at September 30, 2021 $ 3 $ 17 $ 20 _______________ (1) In addition, the Company incurred an additional $1 million of facility-related costs for lease asset impairments in connection with the Facility and Operational Efficiencies Program during the nine months ended September 30, 2021.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS (LOSS) PER SHARE Earnings (loss) per share attributable to Realogy Holdings Basic earnings (loss) per common share is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted earnings (loss) per common share is computed based on the weighted average number of shares of common stock outstanding, plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include shares the Company could be obligated to issue from its Exchangeable Senior Notes and warrants (see Note 4. "Short and Long-Term Debt", to the Condensed Consolidated Financial Statements for further discussion) and unvested stock-based awards. The following table sets forth the computation of basic and diluted earnings (loss) per share: Three Months Ended Nine Months Ended (in millions, except per share data) 2021 2020 2021 2020 Numerator: Net income (loss) attributable to Realogy Holdings shareholders $ 114 $ 98 $ 296 $ (378) Denominator: Weighted average common shares outstanding (denominator for basic earnings (loss) per share calculation) 116.6 115.4 116.3 115.2 Dilutive effect of stock-based compensation 3.7 1.3 3.9 — Dilutive effect of Exchangeable Senior Notes and warrants — — — — Weighted average common shares outstanding (denominator for diluted earnings (loss) per share calculation) 120.3 116.7 120.2 115.2 Earnings (loss) per share attributable to Realogy Holdings shareholders: Basic earnings (loss) per share $ 0.98 $ 0.85 $ 2.55 $ (3.28) Diluted earnings (loss) per share $ 0.95 $ 0.84 $ 2.46 $ (3.28) The three and nine months ended September 30, 2021 exclude 3.8 million and 3.6 million shares, respectively, of common stock issuable for incentive equity awards, which include performance share units based on the achievement of target amounts, that are anti-dilutive to the diluted earnings per share computation. The three months ended September 30, 2020 exclude 8.3 million shares of common stock issuable for incentive equity awards, which include performance share units based on the achievement of target amounts, that are anti-dilutive to the diluted earnings per share computation. The Company was in a net loss position for the nine months ended September 30, 2020 and therefore the impact of incentive equity awards were excluded from the computation of dilutive loss per share as the inclusion of such amounts would be anti-dilutive. Shares to be provided to the Company from the exchangeable note hedge transactions purchased concurrently with its issuance of Exchangeable Senior Notes are anti-dilutive and are not included in its diluted shares.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION The reportable segments presented below represent the Company’s segments for which separate financial information is available and which is utilized on a regular basis by its chief operating decision maker to assess performance and to allocate resources. In identifying its reportable segments, the Company also considers the nature of services provided by its segments. Management evaluates the operating results of each of its reportable segments based upon revenue and Operating EBITDA. Operating EBITDA is defined by us as net income (loss) before depreciation and amortization, interest expense, net (other than relocation services interest for securitization assets and securitization obligations), income taxes, and other items that are not core to the operating activities of the Company such as restructuring charges, former parent legacy items, gains or losses on the early extinguishment of debt, impairments, gains or losses on discontinued operations and gains or losses on the sale of investments or other assets. The Company’s presentation of Operating EBITDA may not be comparable to similar measures used by other companies.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Fair Value Measurement, Policy	The following tables present the Company’s assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level Input: Input Definitions: Level I Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets at the measurement date. Level II Inputs other than quoted prices included in Level I that are observable for the asset or liability through corroboration with market data at the measurement date. Level III Unobservable inputs that reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The availability of observable inputs can vary from asset to asset and is affected by a wide variety of factors, including, for example, the type of asset, whether the asset is new and not yet established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level III. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value of financial instruments is generally determined by reference to quoted market values. In cases where quoted market prices are not available, fair value is based on estimates using present value or other valuation techniques, as appropriate. The fair value of interest rate swaps is determined based upon a discounted cash flow approach. The Company measures financial instruments at fair value on a recurring basis and recognizes transfers within the fair value hierarchy at the end of the fiscal quarter in which the change in circumstances that caused the transfer occurred.

Income Tax, Policy	Income Taxes The Company's provision for income taxes in interim periods is computed by applying its estimated annual effective tax rate against the income before income taxes for the period. In addition, non-recurring or discrete items are recorded in the period in which they occur. The provision for income taxes was an expense of $48 million and $36 million for the three months ended September 30, 2021 and 2020, respectively, and an expense of $125 million and a benefit of $110 million for the nine months ended September 30, 2021 and 2020, respectively.
Derivatives, Policy	Derivative Instruments The Company records derivatives and hedging activities on the balance sheet at their respective fair values. The Company enters into interest rate swaps to manage its exposure to changes in interest rates associated with its variable rate borrowings. As of September 30, 2021, the Company had interest rate swaps with an aggregate notional value of $1,000 million to offset the variability in cash flows resulting from the term loan facilities as follows: Notional Value (in millions) Commencement Date Expiration Date $450 November 2017 November 2022 $400 August 2020 August 2025 $150 November 2022 November 2027 The swaps help to protect our outstanding variable rate borrowings from future interest rate volatility. The Company has not elected to utilize hedge accounting for these interest rate swaps; therefore, any change in fair value is recorded in the Condensed Consolidated Statements of Operations. The fair value of derivative instruments was as follows: Not Designated as Hedging Instruments Balance Sheet Location September 30, 2021 December 31, 2020 Interest rate swap contracts Other non-current liabilities 57 81 The effect of derivative instruments on earnings was as follows: Derivative Instruments Not Designated as Hedging Instruments Location of Loss or (Gain) Recognized for Derivative Instruments Loss or (Gain) Recognized on Derivatives Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Interest rate swap contracts Interest expense $ (1) $ — $ (8) $ 59

Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy	Allowance for Doubtful Accounts The Company estimates the allowance necessary to provide for uncollectible accounts receivable. The estimate is based on historical experience, combined with a review of current conditions and forecasts of future losses, and includes specific accounts for which payment has become unlikely. The process by which the Company calculates the allowance begins in the individual business units where specific problem accounts are identified and reserved primarily based upon the age profile of the receivables and specific payment issues, combined with reasonable and supportable forecasts of future losses.
New Accounting Pronouncements, Policy	Recently Adopted Accounting Pronouncements The Company adopted the new standard on Simplifying the Accounting for Income Taxes effective January 1, 2021. The new standard clarifies and simplifies aspects of the accounting for income taxes to help promote consistent application of GAAP by eliminating certain exceptions to the general principles of ASC Topic 740, Income Taxes. The adoption of this guidance did not have an impact to the Company’s Consolidated Financial Statements upon adoption on January 1, 2021. Recently Issued Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates ("ASUs"). Recently issued standards were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations. The FASB issued its new standard on Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity which simplifies the accounting for instruments with characteristics of liabilities and equity, including convertible debt. The new standard reduces the number of accounting models for convertible debt instruments and convertible preferred stock resulting in fewer embedded conversion features being separately recognized from the host contract and the interest rate of more convertible debt instruments being closer to the coupon interest rate, as compared with current guidance. The new standard also amends the derivative guidance for the “own stock” scope exception, which exempts qualifying instruments from being accounted for as derivatives if certain criteria are met. In addition, the standard changes the diluted earnings per share calculation for instruments that may be settled in cash or shares and for convertible instruments. The new standard is effective for reporting periods beginning on or after December 15, 2021 and permits the use of either the modified retrospective or fully retrospective method of transition. The Company plans to adopt the new standard on January 1, 2022 using the modified retrospective approach and is currently evaluating the impact of adopting this standard on the Company's financial statements.

The Term Loan B Facility provided for quarterly amortization payments totaling 1% per annum of the $1,080 million original principal amount. The interest rate with respect to term loans under the Term Loan B Facility was based on, at the Company’s option, (a) adjusted LIBOR plus 2.25% (with a LIBOR floor of 0.75%) or (b) ABR plus 1.25% (with an ABR floor of 1.75%).

[3]	In September 2021, the Company used cash on hand to repay approximately $197 million
[4]	In January 2021, prior to the effective date of the 2021 Amendments, we used a portion of the proceeds from the issuance of 5.75% Senior Notes to pay down $250 million of outstanding borrowings under the Term Loan A Facility. The interest rates with respect to each of the Non-extended Term Loan A and Extended Term Loan A are based on, at the Company's option, (a) adjusted LIBOR plus an additional margin or (b) ABR plus an additional margin, in each case subject to adjustment based on the then current senior secured leverage ratio. Based on the previous quarter's senior secured leverage ratio, the LIBOR margin was 1.75% and the ABR margin was 0.75% for the three months ended September 30, 2021.
[5]	The Extended Term Loan A has quarterly amortization payments, which commenced on June 30, 2021, equal to a percentage per quarter of the $237 million principal amount of the Extended Term Loan A outstanding on January 27, 2021 (the effective date of the 2021 Amendments), as follows: 0.625% per quarter from June 30, 2021 to March 31, 2022; 1.25% per quarter from June 30, 2022 to March 31, 2023; 1.875% per quarter from June 30, 2023 to March 31, 2024; and 2.50% per quarter for periods ending on or after June 30, 2024, with the balance of the Extended Term Loan A due at maturity on February 8, 2025.
[6]	The maturity date of each of the Extended Revolving Credit Commitment and Extended Term Loan A may spring forward to March 2, 2023 if on or before March 2, 2023, the 4.875% Senior Notes have not been extended, refinanced or replaced to have a maturity date after May 10, 2025 (or are not otherwise discharged, defeased or repaid by March 2, 2023)

[8]	Interest rates with respect to revolving loans under the Senior Secured Credit Facility at September 30, 2021 are based on, at the Company's option, (a) adjusted London Interbank Offering Rate ("LIBOR") plus an additional margin or (b) JP Morgan Chase Bank, N.A.'s prime rate ("ABR") plus an additional margin, in each case subject to adjustment based on the then current senior secured leverage ratio. Based on the previous quarter's senior secured leverage ratio, the LIBOR margin was 1.75% and the ABR margin was 0.75% for the three months ended September 30, 2021.
[9]	The available capacity under the Non-extended Revolving Credit Commitment is $477 million, while the available capacity under the Extended Revolving Credit Commitment is $948 million. As of September 30, 2021, there were no outstanding borrowings under either the Non-extended Revolving Credit Commitment or Extended Revolving Credit Commitment and $42 million of outstanding undrawn letters of credit.

[1]	In January and February 2021, we used a portion of the proceeds from the issuance of 5.75% Senior Notes to pay down $655 million of outstanding borrowings under the Term Loan B Facility. In April 2021, the Company used cash on hand to pay down $150 million of outstanding borrowings under the Term Loan B Facility. In September 2021, the Company used cash on hand to repay approximately $238 million in principal amount of outstanding borrowings under the Term Loan B Facility, representing all of the remaining Term Loan B due 2025. The Term Loan B Facility provided for quarterly amortization payments totaling 1% per annum of the $1,080 million original principal amount. The interest rate with respect to term loans under the Term Loan B Facility was based on, at the Company’s option, (a) adjusted LIBOR plus 2.25% (with a LIBOR floor of 0.75%) or (b) ABR plus 1.25% (with an ABR floor of 1.75%).
[2]	In September 2021, the Company used cash on hand to repay approximately $197 million
[3]	In January 2021, prior to the effective date of the 2021 Amendments, we used a portion of the proceeds from the issuance of 5.75% Senior Notes to pay down $250 million of outstanding borrowings under the Term Loan A Facility. The interest rates with respect to each of the Non-extended Term Loan A and Extended Term Loan A are based on, at the Company's option, (a) adjusted LIBOR plus an additional margin or (b) ABR plus an additional margin, in each case subject to adjustment based on the then current senior secured leverage ratio. Based on the previous quarter's senior secured leverage ratio, the LIBOR margin was 1.75% and the ABR margin was 0.75% for the three months ended September 30, 2021.
[4]	The Extended Term Loan A has quarterly amortization payments, which commenced on June 30, 2021, equal to a percentage per quarter of the $237 million principal amount of the Extended Term Loan A outstanding on January 27, 2021 (the effective date of the 2021 Amendments), as follows: 0.625% per quarter from June 30, 2021 to March 31, 2022; 1.25% per quarter from June 30, 2022 to March 31, 2023; 1.875% per quarter from June 30, 2023 to March 31, 2024; and 2.50% per quarter for periods ending on or after June 30, 2024, with the balance of the Extended Term Loan A due at maturity on February 8, 2025.
[5]	The maturity date of each of the Extended Revolving Credit Commitment and Extended Term Loan A may spring forward to March 2, 2023 if on or before March 2, 2023, the 4.875% Senior Notes have not been extended, refinanced or replaced to have a maturity date after May 10, 2025 (or are not otherwise discharged, defeased or repaid by March 2, 2023)
[6]	Realogy Group may redeem all or a portion of the Unsecured Notes or 7.625% Senior Secured Second Lien Notes, as applicable, at the redemption price set forth in the applicable indenture governing such notes, commencing on the following dates: Date 7.625% Senior Secured Second Lien Notes June 15, 2022 4.875% Senior Notes March 1, 2023 9.375% Senior Notes April 1, 2022 5.75% Senior Notes January 15, 2024
[7]	Interest rates with respect to revolving loans under the Senior Secured Credit Facility at September 30, 2021 are based on, at the Company's option, (a) adjusted London Interbank Offering Rate ("LIBOR") plus an additional margin or (b) JP Morgan Chase Bank, N.A.'s prime rate ("ABR") plus an additional margin, in each case subject to adjustment based on the then current senior secured leverage ratio. Based on the previous quarter's senior secured leverage ratio, the LIBOR margin was 1.75% and the ABR margin was 0.75% for the three months ended September 30, 2021.
[8]	The available capacity under the Non-extended Revolving Credit Commitment is $477 million, while the available capacity under the Extended Revolving Credit Commitment is $948 million. As of September 30, 2021, there were no outstanding borrowings under either the Non-extended Revolving Credit Commitment or Extended Revolving Credit Commitment and $42 million of outstanding undrawn letters of credit. The Non-extended Revolving Credit Commitment expires in February 2023 and, subject to earlier springing maturity described in footnote (3), the Extended Revolving Credit Commitment expires in February 2025, but in each instance, amounts outstanding would be classified on the balance sheet as current due to the revolving nature and terms and conditions of the facilities. On November 1, 2021, the Company had no outstanding borrowings under the Revolving Credit Facility and $42 million of outstanding undrawn letters of credit

In January and February 2021, we used a portion of the proceeds from the issuance of 5.75% Senior Notes to pay down $655 million of outstanding borrowings under the Term Loan B Facility. In April 2021, the Company used cash on hand to pay down $150 million of outstanding borrowings under the Term Loan B Facility. In September 2021, the Company used cash on hand to repay approximately $238 million in principal amount of outstanding borrowings under the Term Loan B Facility, representing all of the remaining Term Loan B due 2025. The Term Loan B Facility provided for quarterly amortization payments totaling 1% per annum of the $1,080 million original principal amount. The interest rate with respect to term loans under the Term Loan B Facility was based on, at the Company’s option, (a) adjusted LIBOR plus 2.25% (with a LIBOR floor of 0.75%) or (b) ABR plus 1.25% (with an ABR floor of 1.75%).

[2]

In September 2021, the Company used cash on hand to repay approximately $197 million

[3]

In January 2021, prior to the effective date of the 2021 Amendments, we used a portion of the proceeds from the issuance of 5.75% Senior Notes to pay down $250 million of outstanding borrowings under the Term Loan A Facility. The interest rates with respect to each of the Non-extended Term Loan A and Extended Term Loan A are based on, at the Company's option, (a) adjusted LIBOR plus an additional margin or (b) ABR plus an additional margin, in each case subject to adjustment based on the then current senior secured leverage ratio. Based on the previous quarter's senior secured leverage ratio, the LIBOR margin was 1.75% and the ABR margin was 0.75% for the three months ended September 30, 2021.

[4]

The Extended Term Loan A has quarterly amortization payments, which commenced on June 30, 2021, equal to a percentage per quarter of the $237 million principal amount of the Extended Term Loan A outstanding on January 27, 2021 (the effective date of the 2021 Amendments), as follows: 0.625% per quarter from June 30, 2021 to March 31, 2022; 1.25% per quarter from June 30, 2022 to March 31, 2023; 1.875% per quarter from June 30, 2023 to March 31, 2024; and 2.50% per quarter for periods ending on or after June 30, 2024, with the balance of the Extended Term Loan A due at maturity on February 8, 2025.

[5]

The maturity date of each of the Extended Revolving Credit Commitment and Extended Term Loan A may spring forward to March 2, 2023 if on or before March 2, 2023, the 4.875% Senior Notes have not been extended, refinanced or replaced to have a maturity date after May 10, 2025 (or are not otherwise discharged, defeased or repaid by March 2, 2023)

[6]

Realogy Group may redeem all or a portion of the Unsecured Notes or 7.625% Senior Secured Second Lien Notes, as applicable, at the redemption price set forth in the applicable indenture governing such notes, commencing on the following dates: Date 7.625% Senior Secured Second Lien Notes June 15, 2022 4.875% Senior Notes March 1, 2023 9.375% Senior Notes April 1, 2022 5.75% Senior Notes January 15, 2024

[7]

Interest rates with respect to revolving loans under the Senior Secured Credit Facility at September 30, 2021 are based on, at the Company's option, (a) adjusted London Interbank Offering Rate ("LIBOR") plus an additional margin or (b) JP Morgan Chase Bank, N.A.'s prime rate ("ABR") plus an additional margin, in each case subject to adjustment based on the then current senior secured leverage ratio. Based on the previous quarter's senior secured leverage ratio, the LIBOR margin was 1.75% and the ABR margin was 0.75% for the three months ended September 30, 2021.

[8]

The available capacity under the Non-extended Revolving Credit Commitment is $477 million, while the available capacity under the Extended Revolving Credit Commitment is $948 million. As of September 30, 2021, there were no outstanding borrowings under either the Non-extended Revolving Credit Commitment or Extended Revolving Credit Commitment and $42 million of outstanding undrawn letters of credit. The Non-extended Revolving Credit Commitment expires in February 2023 and, subject to earlier springing maturity described in footnote (3), the Extended Revolving Credit Commitment expires in February 2025, but in each instance, amounts outstanding would be classified on the balance sheet as current due to the revolving nature and terms and conditions of the facilities. On November 1, 2021, the Company had no outstanding borrowings under the Revolving Credit Facility and $42 million of outstanding undrawn letters of credit

[9]

As of September 30, 2021, the Company had $200 million of borrowing capacity under the Apple Ridge Funding LLC securitization program leaving $56 million of available capacity.

[10]

Available capacity is subject to maintaining sufficient relocation related assets to collateralize these securitization obligations.

[11]

Consists of a £10 million revolving loan facility and a £5 million working capital facility. As of September 30, 2021, the Company had $20 million of borrowing capacity under the Cartus Financing Limited securitization program leaving $18 million of available capacity. In August 2021, Realogy Group extended the existing Cartus Financing Limited securitization program to September 2021 and in September 2021 the program was amended and further extended from October 2021 to September 2022, consisting of a £5 million revolving loan facility and a £5 million working capital facility.

[2]	The Extended Term Loan A has quarterly amortization payments, which commenced on June 30, 2021, equal to a percentage per quarter of the $237 million principal amount of the Extended Term Loan A outstanding on January 27, 2021 (the effective date of the 2021 Amendments), as follows: 0.625% per quarter from June 30, 2021 to March 31, 2022; 1.25% per quarter from June 30, 2022 to March 31, 2023; 1.875% per quarter from June 30, 2023 to March 31, 2024; and 2.50% per quarter for periods ending on or after June 30, 2024, with the balance of the Extended Term Loan A due at maturity on February 8, 2025.
[3]	The maturity date of each of the Extended Revolving Credit Commitment and Extended Term Loan A may spring forward to March 2, 2023 if on or before March 2, 2023, the 4.875% Senior Notes have not been extended, refinanced or replaced to have a maturity date after May 10, 2025 (or are not otherwise discharged, defeased or repaid by March 2, 2023)

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	COMMITMENTS AND CONTINGENCIES Litigation The Company is involved in claims, legal proceedings, alternative dispute resolution and governmental inquiries or regulatory actions related to alleged contract disputes, business practices, intellectual property and other commercial, employment, regulatory and tax matters. Examples of such matters may include but are not limited to allegations: • concerning anti-trust and anti-competition matters (including claims related to NAR or MLS rules regarding buyer broker commissions); • that independent residential real estate sales agents engaged by Realogy Brokerage Group or by affiliated franchisees—under certain state or federal laws—are potentially employees instead of independent contractors, and they or regulators therefore may bring claims against Realogy Brokerage Group for breach of contract, wage and hour classification claims, wrongful discharge, unemployment and workers' compensation and could seek benefits, back wages, overtime, indemnification, penalties related to classification practices and expense reimbursement available to employees or make similar claims against Realogy Franchise Group as an alleged joint employer of an affiliated franchisee’s independent sales agents; • concerning other employment law matters, including other types of worker classification claims as well as wage and hour claims and retaliation claims; • that the Company is vicariously liable for the acts of franchisees under theories of actual or apparent agency; • by current or former franchisees that franchise agreements were breached including improper terminations; • concerning alleged violations of RESPA, state consumer fraud statutes, federal consumer protection statutes or other state real estate law violations; • concerning claims related to the Telephone Consumer Protection Act, including autodialer claims; • concerning claims generally against the company owned brokerage operations for negligence, misrepresentation or breach of fiduciary duty in connection with the performance of real estate brokerage or other professional services as well as other brokerage claims associated with listing information and property history; • related to intellectual property or copyright law, including infringement actions alleging improper use of copyrighted photographs on websites or in marketing materials without consent of the copyright holder or claims challenging our trademarks; • concerning breach of obligations to make websites and other services accessible for consumers with disabilities; • concerning claims generally against the title agent contending that the agent knew or should have known that a transaction was fraudulent or that the agent was negligent in addressing title defects or conducting the settlement; • concerning information security, including claims under new and emerging data privacy laws related to the protection of customer, employee or third-party information; • concerning cyber-crime, including claims related to the diversion of homesale transaction closing funds; • claims related to disclosure or securities law violations as well as derivative suits; and • those related to general fraud claims. Other ordinary court legal proceedings that may arise from time to time include those related to commercial arrangements, indemnification (under contract or common law), franchising arrangements, the fiduciary duties of brokers, standard brokerage disputes like the failure to disclose accurate square footage or hidden defects in the property such as mold, vicarious liability based upon conduct of individuals or entities outside of our control, including franchisees and independent sales agents, claims under the False Claims Act (or similar state laws), consumer lending and debt collection law claims, employment law claims related to business actions responsive to the COVID-19 outbreak and governmental and regulatory directives thereto. While the results of such claims and legal actions cannot be predicted with certainty, we do not believe based on information currently available to us that the final outcome of current proceedings against the Company will have a material adverse effect on our consolidated financial position, results of operations or cash flows. In addition, with the increasing requirements resulting from government laws and regulations concerning data breach notifications and data privacy and protection obligations, claims associated with these laws may become more common. While most litigation involves claims against the Company, from time to time the Company commences litigation, including litigation against former employees, franchisees and competitors when it alleges that such persons or entities have breached agreements or engaged in other wrongful conduct. Worker Classification Litigation Whitlach v. Premier Valley, Inc. d/b/a Century 21 M&M and Century 21 Real Estate LLC (Superior Court of California, Stanislaus County). This was filed as a putative class action complaint on December 20, 2018 by plaintiff James Whitlach against Premier Valley Inc., a Century 21 Real Estate independently-owned franchisee doing business as Century 21 M&M (“Century 21 M&M”). The complaint also names Century 21 Real Estate LLC, a wholly-owned subsidiary of the Company and the franchisor of Century 21 Real Estate (“Century 21”), as an alleged joint employer of the franchisee’s independent sales agents and seeks to certify a class that could potentially include all agents of both Century 21 M&M and Century 21 in California. In February 2019, the plaintiff amended his complaint to assert claims pursuant to the California Private Attorneys General Act (“PAGA”). Following the Court's dismissal of the plaintiff's non-PAGA claims without prejudice in June 2019, the plaintiff filed a second amended complaint asserting one cause of action for alleged civil penalties under PAGA in June 2020 and continued to pursue his PAGA claims as a representative of purported "aggrieved employees" as defined by PAGA. As such representative, the plaintiff seeks all non-individualized relief available to the purported aggrieved employees under PAGA, as well as attorneys’ fees. Under California law, PAGA claims are generally not subject to arbitration and may result in exposure in the form of additional penalties. In the second amended complaint, the plaintiff continues to allege that Century 21 M&M misclassified all of its independent real estate agents, salespeople, sales professionals, broker associates and other similar positions as independent contractors, failed to pay minimum wages, failed to provide meal and rest breaks, failed to pay timely wages, failed to keep proper records, failed to provide appropriate wage statements, made unlawful deductions from wages, and failed to reimburse plaintiff and the putative class for business related expenses, resulting in violations of the California Labor Code. The demurrer filed by Century 21 M&M (and joined by Century 21) on August 3, 2020 to the plaintiff's amended complaint, was granted by the Court on November 10, 2020, dismissing the case without leave to replead. In January 2021, the plaintiff filed a notice of appeal of the Court’s order granting the demurrer and filed its brief in support of the appeal on June 28, 2021. On October 28, 2021, Century 21 and Century 21 M&M filed their appellate brief in opposition to plaintiff’s appeal. This case raises various previously unlitigated claims and the PAGA claim adds additional litigation, financial and operating uncertainties. Real Estate Industry Litigation Moehrl, Cole, Darnell, Nager, Ramey, Sawbill Strategic, Inc., Umpa and Ruh v. The National Association of Realtors, Realogy Holdings Corp., Homeservices of America, Inc., BHH Affiliates, LLC, The Long & Foster Companies, Inc., RE/MAX LLC, and Keller Williams Realty, Inc. (U.S. District Court for the Northern District of Illinois). This amended putative class action complaint (the "amended Moehrl complaint"), filed on June 14, 2019, (i) consolidates the Moehrl and Sawbill litigation reported in our Form 10-Q for the period ended March 31, 2019, (ii) adds certain plaintiffs and defendants, and (iii) serves as a response to the separate motions to dismiss filed on May 17, 2019 in the prior Moehrl litigation by each of NAR and the Company (along with the other defendants named in the prior Moehrl complaint). In the amended Moehrl complaint, the plaintiffs allege that the defendants engaged in a continuing contract, combination, or conspiracy to unreasonably restrain trade and commerce in violation of Section 1 of the Sherman Act because defendant NAR allegedly established mandatory anticompetitive policies for the multiple listing services and its member brokers that require brokers to make an offer of buyer broker compensation when listing a property. The plaintiffs further allege that commission sharing, which provides for the broker representing the seller sharing or paying a portion of its commission to the broker representing the buyer, is anticompetitive and violates the Sherman Act, and that the defendant franchisors conspired with NAR by requiring their respective franchisees to comply with NAR’s policies and Code of Ethics. The plaintiffs seek a permanent injunction enjoining the defendants from requiring home sellers to pay buyer broker commissions or to otherwise restrict competition among buyer brokers, an award of damages and/or restitution, attorneys fees and costs of suit. In October 2019, the Department of Justice ("DOJ") filed a statement of interest for this matter, in their words “to correct the inaccurate portrayal, by defendant The National Association of Realtors (‘NAR’), of a 2008 consent decree between the United States and NAR.” A motion to appoint lead counsel in the case was granted on an interim basis by the Court in May 2020. In October 2020, the Court denied the separate motions to dismiss filed in August 2019 by each of NAR and the Company (together with the other defendants named in the amended Moehrl complaint). Discovery between the plaintiffs and defendants is ongoing. Sitzer and Winger v. The National Association of Realtors, Realogy Holdings Corp., Homeservices of America, Inc., RE/MAX Holdings, Inc., and Keller Williams Realty, Inc. (U.S. District Court for the Western District of Missouri). This is a putative class action complaint filed on April 29, 2019 and amended on June 21, 2019 against NAR, the Company, Homeservices of America, Inc., RE/MAX Holdings, Inc., and Keller Williams Realty, Inc. The complaint contains substantially similar allegations, and seeks the same relief under the Sherman Act, as the Moehrl litigation. The Sitzer litigation is limited both in allegations and relief sought to the State of Missouri and includes an additional cause of action for alleged violation of the Missouri Merchandising Practices Act, or MMPA. On August 22, 2019, the Court denied defendants' motions to transfer the Sitzer matter to the U.S. District Court for the Northern District of Illinois and on October 16, 2019, denied the motions to dismiss this litigation filed respectively by NAR and the Company (together with the other named brokerage/franchisor defendants). In September 2019, the DOJ filed a statement of interest and appearances for this matter for the same purpose stated in the Moehrl matter. In July 2020, the DOJ requested the Company provide it with all materials produced for Sitzer, with such request related to and preceding the subsequent civil lawsuit filed and related settlement agreement between the DOJ and NAR in November 2020. In July 2021, the DOJ filed a notice of withdrawal of consent to its November 2020 proposed settlement with NAR and submitted an additional request to the Company for any supplemental materials produced in Sitzer . Plaintiffs filed their motion for class certification on May 24, 2021 and on June 30, 2021, filed a second amended complaint limiting the class definition to home sellers who used a listing broker affiliated with one of the defendants, among other things. Discovery between the plaintiffs and defendants is ongoing. Leeder v. The National Association of Realtors, Realogy Holdings Corp., Homeservices of America, Inc., BHH Affiliates, LLC, HSF Affiliates, LLC, The Long & Foster Companies, Inc., RE/MAX LLC, and Keller Williams Realty, Inc. (U.S. District Court for the Northern District of Illinois Eastern Division). In this putative class action filed on January 25, 2021, the plaintiff takes issue with certain NAR policies, including those related to buyer broker compensation at issue in the Moehrl and Sitzer matters as well as those at issue in the 2020 settlement between the DOJ and NAR, but claims the alleged conspiracy has harmed buyers (instead of sellers). The plaintiff alleges that the defendants made agreements and engaged in a conspiracy in restraint of trade in violation of the Sherman Act and were unjustly enriched, and seek a permanent injunction enjoining NAR from establishing in the future the same or similar rules, policies, or practices as those challenged in the action as well as an award of damages and/or restitution, interest, and reasonable attorneys’ fees and expenses. The Company (together with the other companies named in the complaint) filed a motion to dismiss the complaint on April 20, 2021 and, on June 4, 2021, the plaintiff filed his opposition to which the defendants replied on July 6, 2021. Rubenstein, Nolan v. The National Association of Realtors, Realogy Holdings Corp., Coldwell Banker, Sotheby’s Investment Realty, and Homeservices of America, Inc. (U.S. District Court for the District of Connecticut). On July 26, 2021, the Court dismissed this action with prejudice. Bauman, Bauman and Nosalek v. MLS Property Information Network, Inc., Realogy Holdings Corp., Homeservices of America, Inc., BHH Affiliates, LLC, HSF Affiliates, LLC, RE/MAX LLC, and Keller Williams Realty, Inc. (U.S. District Court for the District of Massachusetts). This is a putative class action filed on December 17, 2020, wherein the plaintiffs take issue with policies and rules similar to those at issue in the Moehrl , Sitzer and Rubenstein matters, but rather than objecting to the national policies and rules published by NAR, this lawsuit specifically objects to the alleged policies and rules of a multiple listing service that is owned by realtors, including in part by one of Realogy’s company-owned brokerages. The plaintiffs allege that the defendants made agreements and engaged in a conspiracy in restraint of trade in violation of the Sherman Act and seek a permanent injunction, enjoining the defendants from continuing conduct determined to be unlawful, as well as an award of damages and/or restitution, interest, and reasonable attorneys’ fees and expenses. The Company (together with the other companies named in the complaint) filed a motion to dismiss the complaint in March 2021 and, on April 15, 2021, the plaintiffs filed their opposition to which the defendants replied on May 17, 2021. Company-Initiated Litigation and Related Counterclaims Realogy Holdings Corp., NRT New York LLC (d/b/a The Corcoran Group), Sotheby’s International Realty, Inc., Coldwell Banker Residential Brokerage Company, Coldwell Banker Residential Real Estate LLC, NRT West, Inc., Martha Turner Properties, L.P. And Better Homes and Gardens Real Estate LLC v. Urban Compass, Inc., and Compass, Inc. (Supreme Court New York, New York County). On July 10, 2019, the Company and certain of its subsidiaries filed a complaint against Urban Compass, Inc. and Compass, Inc. (together, "Compass"), which was subsequently amended by the Company. The Company’s current complaint alleges misappropriation of trade secrets; tortious interference with contract; intentional and tortious interference with prospective economic advantage; unfair competition under New York common law; violations of the California Unfair Competition Law, Business and Professional Code Section 17200 et. seq. (unfair competition); violations of New York General Business Law Section 349 (deceptive acts or practices); violations of New York General Business Law Sections 350 and 350-a (false advertising); conversion; and defamation. The Company seeks, among other things, actual and compensatory damages, injunctive relief, and attorneys’ fees and costs. In January 2021, Compass filed its answer to the Company’s amended complaint, as well as counterclaims and third-party claims against the Company and certain of its subsidiaries, alleging unfair competition, tortious interference with prospective business relations, defamation, injurious falsehoods, and misappropriation of trade secrets. Compass seeks compensatory and punitive damages, injunctive relief, disgorgement of profits, interest and attorneys’ fees. In March 2021, the Company filed a motion to dismiss (with respect to certain counterclaims) and a reply (to the remaining counts of the counterclaims). On April 22, 2021, pursuant to a stipulation of the parties, the Court ordered the dismissal without prejudice of Compass’s third-party claims and those counterclaims against the Company related to unfair competition under New York common law, conspiracy and misappropriation of trade secrets. Discovery in the case is continuing. The Company disputes the allegations against it in each of the captioned matters described above and will vigorously defend these actions. Given the early stages of each of these cases, we cannot estimate a range of reasonably possible losses for this litigation. The Company believes that it has adequately accrued for legal matters as appropriate. The Company records litigation accruals for legal matters which are both probable and estimable. Litigation and other disputes are inherently unpredictable and subject to substantial uncertainties and unfavorable resolutions could occur. In addition, class action lawsuits can be costly to defend and, depending on the class size and claims, could be costly to settle. As such, the Company could incur judgments or enter into settlements of claims with liability that are materially in excess of amounts accrued and these settlements could have a material adverse effect on the Company’s financial condition, results of operations or cash flows in any particular period. * * * Cendant Corporate Liabilities and Guarantees to Cendant and Affiliates Realogy Group (then Realogy Corporation) separated from Cendant on July 31, 2006 (the "Separation"), pursuant to a plan by Cendant (now known as Avis Budget Group, Inc.) to separate into four independent companies—one for each of Cendant's business units—real estate services (Realogy Group), travel distribution services ("Travelport"), hospitality services, including timeshare resorts ("Wyndham Worldwide"), and vehicle rental ("Avis Budget Group"). Pursuant to the Separation and Distribution Agreement dated as of July 27, 2006 among Cendant, Realogy Group, Wyndham Worldwide and Travelport (the "Separation and Distribution Agreement"), each of Realogy Group, Wyndham Worldwide and Travelport have assumed certain contingent and other corporate liabilities (and related costs and expenses), which are primarily related to each of their respective businesses. In addition, Realogy Group has assumed 62.5% and Wyndham Worldwide has assumed 37.5% of certain contingent and other corporate liabilities (and related costs and expenses) of Cendant. The due to former parent balance was $19 million at both September 30, 2021 and December 31, 2020. The due to former parent balance was comprised of the Company’s portion of the following: (i) Cendant’s remaining contingent tax liabilities, (ii) potential liabilities related to Cendant’s terminated or divested businesses, and (iii) potential liabilities related to the residual portion of accruals for Cendant operations. Tax Matters The Company is subject to income taxes in the United States and several foreign jurisdictions. Significant judgment is required in determining the worldwide provision for income taxes and recording related assets and liabilities. In the ordinary course of business, there are many transactions and calculations where the ultimate tax determination is uncertain. The Company is regularly under audit by tax authorities whereby the outcome of the audits is uncertain. The Company believes there is appropriate support for positions taken on its tax returns. The liabilities that have been recorded represent the best estimates of the probable loss on certain positions and are adequate for all open years based on an assessment of many factors including past experience and interpretations of tax law applied to the facts of each matter. However, the outcomes of tax audits are inherently uncertain. Escrow and Trust Deposits As a service to its customers, the Company administers escrow and trust deposits which represent undisbursed amounts received for the settlement of real estate transactions. Deposits at FDIC-insured institutions are insured up to $250 thousand. These escrow and trust deposits totaled $1,016 million at September 30, 2021 and $585 million at December 31, 2020, respectively. These escrow and trust deposits are not assets of the Company and, therefore, are excluded from the
