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 March 31, 2021 and the results of operations and comprehensive income (loss) for the three months ended March 31, 2021 and 2020 and cash flows for the three months ended March 31, 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 March 31, 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) — 63 — 63 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 March 31, 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: March 31, 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 390 385 1,048 1,032 Term Loan A Facility: Non-extended Term Loan A 197 194 684 671 Extended Term Loan A 237 234 — — 7.625% Senior Secured Second Lien Notes 550 598 550 595 4.875% Senior Notes 407 419 407 415 9.375% Senior Notes 550 609 550 609 5.75% Senior Notes 900 889 — — _______________ (a) The fair value of the Company's indebtedness is categorized as Level II. Equity Method Investments At March 31, 2021 and December 31, 2020, the Company had various equity method investments which are recorded within other non-current assets on the accompanying Condensed Consolidated Balance Sheets. The Company's investment in Guaranteed Rate Affinity, LLC ("Guaranteed Rate Affinity") at Realogy Title Group had an investment balance of $90 million at both March 31, 2021 and December 31, 2020. The Company recorded equity earnings of $30 million and $9 million related to its investment in Guaranteed Rate Affinity for the first quarter of 2021 and 2020, respectively. The Company received $30 million in cash dividends from Guaranteed Rate Affinity during the three months ended March 31, 2021 and no cash dividends during the three months ended March 31, 2020. The Company's other equity method investments had investment balances totaling $12 million and $10 million at March 31, 2021 and December 31, 2020, respectively. The Company recorded $1 million equity earnings from the operations of these equity method investments in the first quarter of 2021 and recorded no equity earnings or losses for the first quarter of 2020. The Company received $1 million in cash dividends from these equity method investments during both the three months ended March 31, 2021 and 2020. 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 $17 million and a benefit of $141 million for the three months ended March 31, 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 March 31, 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 March 31, 2021 December 31, 2020 Interest rate swap contracts Other non-current liabilities 63 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 March 31, 2021 2020 Interest rate swap contracts Interest expense $ (13) $ 51 Restricted Cash Restricted cash primarily relates to amounts specifically designated as collateral for the repayment of outstanding borrowings under the Company’s securitization facilities. Such amounts approximated $5 million at March 31, 2021 and $3 million at December 31, 2020. 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. The Company's revenue is disaggregated by major revenue categories on our Condensed Consolidated Statements of Operations and further disaggregated by business segment as follows: Three Months Ended March 31, Realogy Franchise Group Realogy Brokerage Group Realogy Title Corporate and Other Total 2021 2020 2021 2020 2021 2020 2021 2020 2021 2020 Gross commission income (a) $ — $ — $ 1,154 $ 850 $ — $ — $ — $ — $ 1,154 $ 850 Service revenue (b) 47 64 7 5 195 133 — — 249 202 Franchise fees (c) 181 127 — — — — (76) (56) 105 71 Other (d) 26 29 10 14 6 4 (3) (2) 39 45 Net revenues $ 254 $ 220 $ 1,171 $ 869 $ 201 $ 137 $ (79) $ (58) $ 1,547 $ 1,168 ______________ (a) Gross commission income at Realogy Brokerage Group is recognized at a point in time at the closing of a homesale transaction. (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.

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 $1 million and $4 million during the three months ended March 31, 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 March 31, 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 with early adoption permitted as of January 1, 2021. The new standard requires adoption using either a full or modified retrospective approach and is not expected to have an impact on the Company's financial statements.

(1) 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 March 31, 2021, there were no outstanding borrowings under either the Non-extended Revolving Credit Commitment or Extended Revolving Credit Commitment and $43 million of outstanding undrawn letters of credit. The Non-extended Revolving Credit Commitment expires in February 2023 and, subject to earlier spring 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 May 3, 2021, the Company had no outstanding borrowings under the Revolving Credit Facility and $43 million of outstanding undrawn letters of credit. (2) Interest rates with respect to revolving loans under the Senior Secured Credit Facility at March 31, 2021 were 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 March 31, 2021. (3) The maturity date of each of the Extended Revolving Credit Commitment and Extended Term Loan A may spring forward to a date prior to February 2025 as follows: (i) 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 Revolving Credit Commitment and Extended Term Loan A Facility will be March 2, 2023; and (ii) if on or before November 9, 2024, the Term Loan B Facility under the Senior Secured Credit Agreement is not extended, refinanced or replaced to have a maturity date after May 10, 2025 (or otherwise repaid prior to November 9, 2024), the maturity date of the Extended Revolving Credit Commitment and Extended Term Loan A Facility will be November 9, 2024. (4) 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. The Term Loan B Facility provides 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 is 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%). On April 28, 2021, the Company used cash on hand to pay down $150 million of the Term Loan B Facility. (5) 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 March 31, 2021. (6) The Company is not required to make amortization payments on the Non-extended Term Loan A. The balance of the Non-Extended Term Loan A is due at maturity on February 8, 2023. (7) The Extended Term Loan A has quarterly amortization payments, commencing with the quarter ending 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. (8) Available capacity is subject to maintaining sufficient relocation related assets to collateralize these securitization obligations. (9) As of March 31, 2021, the Company had $200 million of borrowing capacity under the Apple Ridge Funding LLC securitization program leaving $103 million of available capacity. (10) Consists of a £10 million revolving loan facility and a £5 million working capital facility. As of March 31, 2021, the Company had $21 million of borrowing capacity under the Cartus Financing Limited securitization program leaving $18 million of available capacity. Maturities Table As of March 31, 2021, the combined aggregate amount of maturities for long-term borrowings for the remainder of 2021 and each of the next four years is as follows: Year Amount Remaining 2021 (a) $ 12 2022 21 2023 631 2024 33 2025 1,084 _______________ (a) Remaining 2021 includes amortization payments totaling $4 million and $8 million for the Extended Term Loan A and Term Loan B Facility, respectively. The current portion of long-term debt of $17 million shown on the Condensed Consolidated Balance Sheets consists of four quarters of amortization payments totaling $6 million and $11 million for the Extended Term Loan A and Term Loan B Facility, respectively. 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 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 January 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. Furthermore, on January 27, 2021, Realogy Group entered into amendments to the Senior Secured Credit Agreement, referred to collectively herein as the "2021 Amendments", which among other things: • extend the maturity for approximately $237 million of the approximately $434 million outstanding loans under the Term Loan A Facility (the "Extended Term Loan A") after giving effect to the application of the proceeds of the 5.75% Senior Notes offering, from February 2023 to February 2025, subject to the following: ◦ 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 will be March 2, 2023; and ◦ if on or before November 9, 2024, the Term Loan B Facility under the Senior Secured Credit Agreement is not extended, refinanced or replaced to have a maturity date after May 10, 2025 (or otherwise repaid prior to November 9, 2024), the maturity date of the Extended Term Loan A will be November 9, 2024; • extend the maturity of approximately $948 million of the $1,425 million in commitments under the Revolving Credit Facility (the "Extended Revolving Credit Commitment") from February 2023 to February 2025, subject to the earlier springing maturity dates applicable to the Extended Term Loan A described above; and • make certain modifications to the Senior Secured Credit Agreement and Term Loan A Agreement, including amendments that reduced the maximum permitted senior secured leverage ratio (the financial covenant under such agreements) for the applicable trailing twelve-month period to below the levels that had been permitted under the amendments to the Senior Secured Credit Agreement and Term Loan A Agreement that Realogy Group entered into on July 24, 2020 (referred to collectively herein as the "2020 Amendments"), as follows: Fiscal Quarter Ending Senior Secured Leverage Ratio December 31, 2020 to June 30, 2021 5.25 to 1.00 September 30, 2021 to March 31, 2022 5.00 to 1.00 June 30, 2022 and thereafter 4.75 to 1.00 Certain other covenants in the Senior Secured Credit Agreement and Term Loan A Agreement that were tightened under the 2020 Amendments will remain in place under the 2021 Amendments until the Company issues its financial results for the third quarter of 2021 and concurrently delivers an officer’s certificate to its lenders showing compliance with the senior secured leverage ratio set forth in the above table, subject to earlier termination, which we refer to as the covenant period. If Realogy Group’s senior secured leverage ratio does not exceed 5.00 to 1.00 for the fiscal quarter ending June 30, 2021 (as compared to 5.50 to 1.00 under the 2020 Amendments), the covenant period will end at the time Realogy Group delivers the compliance certificate to the lenders for such period; however, in either instance, the gradual step down in the senior secured leverage ratio described above will continue to apply. The covenants tightened during this covenant period include the reduction or elimination of the amount available for certain types of additional indebtedness, liens, restricted payments (including dividends and stock repurchases), investments (including acquisitions and joint ventures), and voluntary junior debt repayments. As was the case under the 2020 Amendments, Realogy Group also may elect to end the covenant period at any time, provided the senior secured leverage ratio does not exceed 4.75 to 1.00 as of the most recently ended quarter for which financial statements have been delivered. In such event, the senior secured leverage ratio will reset to the pre-amendment level of 4.75 to 1.00 thereafter. Senior Secured Credit Facility The Senior Secured Credit Facility includes: (a) 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 has 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 is 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%); and (b) 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 spring 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% 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. As of March 31, 2021, under the 2021 Amendments, Realogy Group was required to maintain a senior secured leverage ratio not to exceed 5.25 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. At March 31, 2021, Realogy Group was in compliance with the senior secured leverage ratio covenant with a senior secured leverage ratio of 0.64 to 1.00 . For the calculation of the senior secured leverage ratio for the first 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 and include the Non-extended Term Loan A due February 2023 and Extended Term Loan A due February 2025, subject to earlier spring maturity described above. The Extended Term Loan A provides for quarterly amortization based on a percentage of the principal amount of $237 million, commencing with the quarter ending 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 are 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 In January and February 2021, the Company issued an aggregate principal amount of $900 million of 5.75% Senior Notes due 2029 and used the gross proceeds of $905 million to repay $250 million of outstanding borrowings under the Term Loan A Facility and $655 million of outstanding borrowings under the Term Loan B Facility. 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 (commencing 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. Securitization Obligations Realogy Group has secured obligations through Apple Ridge Funding LLC under a securitization program which expires in June 2021. As of March 31, 2021, the Company had $200 million of borrowing capacity under the Apple Ridge Funding LLC securitization program with $97 million being utilized, leaving $103 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 which expires in August 2021. As of March 31, 2021, there were $3 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 program and as new eligible relocation management agreements are entered into, the new agreements are designated to the program. The Apple Ridge program has restrictive covenants and trigger events, including performance triggers linked to the age and quality of the underlying assets, foreign obligor limits, multicurrency limits, financial reporting requirements, restrictions on mergers and change of control, any uncured breach of Realogy Group’s senior secured leverage ratio under Realogy Group’s Senior Secured Credit Facility, and cross-defaults to Realogy Group’s material indebtedness. The occurrence of a trigger event under the Apple Ridge securitization facility could restrict our ability to access new or existing funding under this facility or result in termination of the facility, either of which would adversely affect the operation of the Company's relocation services. Certain of the funds that Realogy Group receives from relocation receivables and related assets are required to be utilized to repay securitization obligations. These obligations are collateralized by $134 million and $135 million of underlying relocation receivables and other related relocation assets at March 31, 2021 and December 31, 2020, respectively. Substantially all relocation related assets are realized in less than twelve months from the transaction date. Accordingly, all of Realogy Group's securitization obligations are classified as current in the accompanying Consolidated Balance Sheets. Interest incurred in connection with borrowings under these facilities amounted to $1 million and $2 million for the three months ended March 31, 2021 and 2020, respectively. This interest is recorded within net revenues in the accompanying Condensed Consolidated Statements of Operations as related borrowings are utilized to fund Realogy Group's relocation operations where interest is generally earned on such assets. These securitization obligations represent floating rate debt for which the average weighted interest rate was 3.9% and 3.8% for the three months ended March 31, 2021 and 2020, respectively. Gain/Loss on the Early Extinguishment of Debt and Write-Off of Financing Costs As a result of the refinancing transactions in January and February 2021, the Company recorded a loss on the early extinguishment of debt of $17 million and wrote off certain financing costs of $1 million to interest expense during the three months ended March 31, 2021.

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities Disclosure	. RESTRUCTURING COSTS Restructuring charges were $5 million and $12 million for the three months ended March 31, 2021 and 2020, respectively. The components of the restructuring charges for the three months ended March 31, 2021 and 2020 were as follows: Three Months Ended March 31, 2021 2020 Personnel-related costs (1) $ 2 $ 3 Facility-related costs (2) 3 9 Total restructuring charges $ 5 $ 12 _______________ (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 have worked to comply with state and local regulators to ensure safe working conditions. Many of the Company's employees continued to 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 additional facility initiatives are expected 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) 2 3 5 Costs paid or otherwise settled (4) (5) (9) Balance at March 31, 2021 $ 3 $ 20 $ 23 _______________ (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 three months ended March 31, 2021. The following table shows the total costs currently expected to be incurred by type of cost related to the Facility and Operational Efficiencies Program: Total amount expected to be incurred (1) Amount incurred Total amount remaining to be incurred (1) Personnel-related costs $ 56 $ 52 $ 4 Facility-related costs 109 64 45 Other restructuring costs 1 1 — Total $ 166 $ 117 $ 49 _______________ (1) Facility-related costs include potential lease asset impairments to be incurred under the Facility and Operational Efficiencies Program.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS (LOSS) PER SHARE Earnings (loss) per share attributable to Realogy Holdings Basic earnings (loss) per share is computed based on net income (loss) attributable to Realogy Holdings stockholders divided by the basic weighted-average shares outstanding during the period. Dilutive earnings (loss) per share is computed consistently with the basic computation while giving effect to all dilutive potential common shares and common share equivalents that were outstanding during the period. Realogy Holdings uses the treasury stock method to reflect the potential dilutive effect of unvested stock awards and unexercised options. The following table sets forth the computation of basic and diluted earnings (loss) per share: Three Months Ended March 31, (in millions, except per share data) 2021 2020 Numerator: Net income (loss) attributable to Realogy Holdings shareholders $ 33 $ (462) Denominator: Weighted average common shares outstanding (denominator for basic earnings (loss) per share calculation) 115.9 114.7 Dilutive effect of stock-based compensation (a)(b) 2.5 — Weighted average common shares outstanding (denominator for diluted earnings (loss) per share calculation) 118.4 114.7 Earnings (loss) per share attributable to Realogy Holdings shareholders: Basic earnings (loss) per share $ 0.28 $ (4.03) Diluted earnings (loss) per share $ 0.28 $ (4.03) _______________ (a) The three months ended March 31, 2021 exclude 5.8 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. (b) The Company was in a net loss position for the three months ended March 31, 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.

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. The following table summarizes fair value measurements by level at March 31, 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) — 63 — 63 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 March 31, 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: March 31, 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 390 385 1,048 1,032 Term Loan A Facility: Non-extended Term Loan A 197 194 684 671 Extended Term Loan A 237 234 — — 7.625% Senior Secured Second Lien Notes 550 598 550 595 4.875% Senior Notes 407 419 407 415 9.375% Senior Notes 550 609 550 609 5.75% Senior Notes 900 889 — — _______________ (a) The fair value of the Company's indebtedness is categorized as Level II.
Equity Method Investments, Policy	Equity Method Investments At March 31, 2021 and December 31, 2020, the Company had various equity method investments which are recorded within other non-current assets on the accompanying Condensed Consolidated Balance Sheets. The Company's investment in Guaranteed Rate Affinity, LLC ("Guaranteed Rate Affinity") at Realogy Title Group had an investment balance of $90 million at both March 31, 2021 and December 31, 2020. The Company recorded equity earnings of $30 million and $9 million related to its investment in Guaranteed Rate Affinity for the first quarter of 2021 and 2020, respectively. The Company received $30 million in cash dividends from Guaranteed Rate Affinity during the three months ended March 31, 2021 and no cash dividends during the three months ended March 31, 2020. The Company's other equity method investments had investment balances totaling $12 million and $10 million at March 31, 2021 and December 31, 2020, respectively. The Company recorded $1 million equity earnings from the operations of these equity method investments in the first quarter of 2021 and recorded no equity earnings or losses for the first quarter of 2020. The Company received $1 million in cash dividends from these equity method investments during both the three months ended March 31, 2021 and 2020.
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 $17 million and a benefit of $141 million for the three months ended March 31, 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 March 31, 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 March 31, 2021 December 31, 2020 Interest rate swap contracts Other non-current liabilities 63 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 March 31, 2021 2020 Interest rate swap contracts Interest expense $ (13) $ 51

(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.

(d) New development closings generally have a development period of between 18 and 24 months from contracted date to closing.
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.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy	Restricted Cash Restricted cash primarily relates to amounts specifically designated as collateral for the repayment of outstanding borrowings under the Company’s securitization facilities. Such amounts approximated $5 million at March 31, 2021 and $3 million at December 31, 2020.
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

[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 March 31, 2021.
[4]	The Company is not required to make amortization payments on the Non-extended Term Loan A. The balance of the Non-Extended Term Loan A is due at maturity on February 8, 2023.
[5]	The Extended Term Loan A has quarterly amortization payments, commencing with the quarter ending 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]	Interest rates with respect to revolving loans under the Senior Secured Credit Facility at March 31, 2021 were 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 March 31, 2021.
[7]	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 March 31, 2021, there were no outstanding borrowings under either the Non-extended Revolving Credit Commitment or Extended Revolving Credit Commitment and $43 million of outstanding undrawn letters of credit. The Non-extended Revolving Credit Commitment expires in February 2023 and, subject to earlier spring 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 May 3, 2021, the Company had no outstanding borrowings under the Revolving Credit Facility and $43 million of outstanding undrawn letters of credit
[8]	The maturity date of each of the Extended Revolving Credit Commitment and Extended Term Loan A may spring forward to a date prior to February 2025 as follows: (i) 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 Revolving Credit Commitment and Extended Term Loan A Facility will be March 2, 2023; and (ii) if on or before November 9, 2024, the Term Loan B Facility under the Senior Secured Credit Agreement is not extended, refinanced or replaced to have a maturity date after May 10, 2025 (or otherwise repaid prior to November 9, 2024), the maturity date of the Extended Revolving Credit Commitment and Extended Term Loan A Facility will be November 9, 2024

[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. The Term Loan B Facility provides 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 is 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%). On April 28, 2021, the Company used cash on hand to pay down $150 million of the Term Loan B Facility.
[2]	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 March 31, 2021.
[3]	The Company is not required to make amortization payments on the Non-extended Term Loan A. The balance of the Non-Extended Term Loan A is due at maturity on February 8, 2023.
[4]	The Extended Term Loan A has quarterly amortization payments, commencing with the quarter ending 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]	Interest rates with respect to revolving loans under the Senior Secured Credit Facility at March 31, 2021 were 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 March 31, 2021.
[6]	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 March 31, 2021, there were no outstanding borrowings under either the Non-extended Revolving Credit Commitment or Extended Revolving Credit Commitment and $43 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. The Term Loan B Facility provides 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 is 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%). On April 28, 2021, the Company used cash on hand to pay down $150 million of the Term Loan B Facility.
[2]	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 March 31, 2021.

[5]	Interest rates with respect to revolving loans under the Senior Secured Credit Facility at March 31, 2021 were 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.

[1]	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 March 31, 2021.
