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 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. Certain reclassifications have been made to prior period amounts to conform to the current period presentation. 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, 2018 and the results of operations and comprehensive income for the three and nine months ended September 30, 2018 and 2017 and cash flows for the nine months ended September 30, 2018 and 2017 . The Consolidated Balance Sheet at December 31, 2017 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, 2017 . 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, 2018 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) $ 2 $ — $ — $ 2 Interest rate swaps (included in other non-current assets) — 15 — 15 Interest rate swaps (included in other non-current liabilities) — 2 — 2 Contingent consideration for acquisitions (included in accrued expenses and other current liabilities and other non-current liabilities) — — 11 11 The following table summarizes fair value measurements by level at December 31, 2017 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) $ 3 $ — $ — $ 3 Interest rate swaps (included in other current and non-current liabilities) — 13 — 13 Contingent consideration for acquisitions (included in accrued expenses and other current liabilities and other non-current liabilities) — — 34 34 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, 2017 $ 34 Additions: contingent consideration related to acquisitions completed during the period 1 Reductions: payments of contingent consideration (22 ) Changes in fair value (reflected in the Condensed Consolidated Statement of Operations) (2 ) Fair value of contingent consideration at September 30, 2018 $ 11 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, 2018 December 31, 2017 Debt Principal Amount Estimated Principal Amount Estimated Senior Secured Credit Facility: Revolving Credit Facility $ 250 $ 250 $ 70 $ 70 Term Loan B 1,072 1,073 1,083 1,085 Term Loan A Facility: Term Loan A 741 741 391 393 Term Loan A-1 — — 342 343 4.50% Senior Notes 450 452 450 457 5.25% Senior Notes 550 549 550 569 4.875% Senior Notes 500 467 500 495 Securitization obligations 264 264 194 194 _______________ (a) The fair value of the Company's indebtedness is categorized as Level II. Equity Method Investments At September 30, 2018 and December 31, 2017 , the Company had various equity method investments aggregating $53 million and $74 million , respectively, which are recorded within other non-current assets on the accompanying Condensed Consolidated Balance Sheets. The $53 million investment balance at September 30, 2018 included $46 million for the Company's investment in Guaranteed Rate Affinity, LLC ("Guaranteed Rate Affinity"). The Company's interest in PHH Home Loans, LLC ("PHH Home Loans") was sold to a subsidiary of PHH Corporation in the first quarter of 2018. The $74 million investment balance at December 31, 2017 included $48 million for the Company's investment in Guaranteed Rate Affinity and $19 million for the Company's remaining investment in PHH Home Loans. The Company received net cash proceeds of $19 million reducing the investment balance in PHH Home Loans to zero in the first quarter of 2018. For the three and nine months ended September 30, 2018 , the Company recorded equity losses of $1 million and $3 million , respectively, at the Title and Settlement Services segment primarily related to costs associated with the ramp up of operations of Guaranteed Rate Affinity. The Company recorded $10 million and $7 million of earnings related to its equity investments for the three and nine months ended September 30, 2017 , respectively, primarily related to earnings from the first two phases of the sale of PHH Home Loans' assets to Guaranteed Rate Affinity, partially offset by the recognition of certain exit costs at PHH Home Loans. The Company received $3 million and $24 million in cash dividends from equity method investments during the nine months ended September 30, 2018 and 2017 , respectively. The Company invested $4 million into Guaranteed Rate Affinity during the first quarter of 2018 and $34 million into Guaranteed Rate Affinity during the nine months ended September 30, 2017 . 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 $40 million and $67 million for the three months ended September 30, 2018 and 2017 , respectively, and an expense of $73 million and $131 million for the nine months ended September 30, 2018 and 2017 , respectively. Derivative Instruments The Company records derivatives and hedging activities on the balance sheet at their respective fair values. The Company uses foreign currency forward contracts largely to manage its exposure to changes in foreign currency exchange rates associated with its foreign currency denominated receivables and payables. The Company primarily manages its foreign currency exposure to the Euro, British Pound, Swiss Franc and Canadian Dollar. The Company has not elected to utilize hedge accounting for these forward contracts; therefore, any change in fair value is recorded in the Condensed Consolidated Statements of Operations. However, the fluctuations in the value of these forward contracts generally offset the impact of changes in the value of the underlying risk that they are intended to economically hedge. As of September 30, 2018 , the Company had outstanding foreign currency forward contracts in an asset position with a fair value of less than $1 million and a notional value of $27 million . As of December 31, 2017 , the Company had outstanding foreign currency forward contracts in a liability position with a fair value of less than $1 million and a notional value of $25 million . The Company also enters into interest rate swaps to manage its exposure to changes in interest rates associated with its variable rate borrowings. Interest rate swaps with a notional value of $425 million expired February 10, 2018. As of September 30, 2018 , the Company had interest rate swaps with an aggregate notional value of $1,600 million to offset the variability in cash flows resulting from the term loan facilities as follows: Notional Value (in millions) Commencement Date Expiration Date $600 August 2015 August 2020 $450 November 2017 November 2022 $400 (a) August 2020 August 2025 $150 (a) November 2022 November 2027 _______________ (a) During the second quarter of 2018, the Company entered into four new forward starting interest rate swaps, two with a notional value of $125 million and two with a notional value of $150 million . 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, 2018 December 31, 2017 Interest rate swap contracts Other non-current assets $ 15 $ — Other current and non-current liabilities 2 13 The effect of derivative instruments on earnings was as follows: Derivative Instruments Not Designated as Hedging Instruments Location of (Gain) or Loss Recognized for Derivative Instruments (Gain) or Loss Recognized on Derivatives Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 Interest rate swap contracts Interest expense $ (7 ) $ — $ (19 ) $ 4 Foreign exchange contracts Operating expense — 1 (1 ) 2 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 $11 million and $7 million at September 30, 2018 and December 31, 2017 , respectively. Supplemental Cash Flow Information Significant non-cash transactions during the nine months ended September 30, 2018 and 2017 included capital lease additions of $11 million and $13 million , respectively, which resulted in non-cash additions to property and equipment, net and other non-current liabilities. Recently Adopted Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (Topic 606) " Revenue from Contracts with Customers " (the "new revenue standard"). The objective of the new revenue standard is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries, and across capital markets. After a review of the Company's revenue streams, the Company determined that the new revenue standard did not have a material impact on financial results as the majority of the Company's revenue is recognized at the completion of a homesale transaction which did not result in a change in the timing of recognition of revenue transactions under the new revenue standard. The Company adopted the new revenue standard on January 1, 2018 using the modified retrospective transition method in which the cumulative effect of applying the new revenue standard was recognized as an adjustment to the opening balance of retained earnings. See Note 2, "Revenue Recognition" for further details. In February 2018, the FASB issued a new standard which permits companies to reclassify certain income tax effects resulting from the 2017 Tax Act, called "stranded tax effects", from accumulated other comprehensive income ("AOCI") to retained earnings. According to the new guidance, the reclassification amount should include the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances, if any, at the date of enactment of the 2017 Tax Act related to items remaining in AOCI. The guidance is effective for all companies for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption is permitted. The Company early adopted this standard in the first quarter of 2018 which resulted in a debit to Accumulated other comprehensive loss and a credit to Accumulated deficit for $9 million . The Company’s accounting policy for releasing income tax effects from AOCI is to release those effects when our entire portfolio of the type of item is liquidated. In June 2018, the FASB issued a new standard related to non-employee share-based payment accounting. The new guidance eliminates specific accounting for non-employee share-based payments and aligns the treatment for awards issued to employees and non-employees reducing the complexity of measurement of non-employee awards and creating a single accounting model. The new standard is applied to all new awards granted after the date of adoption. In addition, all liability-classified awards that have not been settled and equity-classified awards for which a measurement date has not been established by the adoption date should be remeasured at fair value as of the adoption date with a cumulative effect adjustment to opening retained earnings in the fiscal year of adoption. If early adoption of the new guidance is chosen in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The Company elected to early adopt this guidance during the second quarter of 2018. There was an immaterial impact upon adoption. Recently Issued Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates ("ASUs"). ASUs not listed below 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. In February 2016, the FASB issued its new standard on leases which requires virtually all leases to be recognized on the balance sheet. Lessees will recognize a right-of-use asset and a lease liability for all leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for lease incentives, prepayments and initial direct costs. For income statement purposes, leases will be classified as either operating or finance leases. Operating leases will result in straight-line expense, similar to current operating leases, while finance leases will result in a front-loaded expense pattern, similar to current capital leases. Classification will be based on criteria that are largely similar to those applied in current lease accounting, but without explicit bright lines. The new standard is effective on January 1, 2019, with early adoption permitted, requiring a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial application. In July 2018, the FASB issued an ASU that allows entities to elect an optional transition relief giving companies the option to apply the provisions of the new guidance at the effective date (e.g., January 1, 2019), as opposed to the earliest comparative period presented in the financial statements under the modified retrospective transition approach (January 1, 2017), and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company will adopt the new standard during the first quarter of 2019 and will elect the optional transition relief. The new standard allows for an optional package of practical expedients during transition which permit companies to not reassess prior conclusions about lease identification, lease classification and initial direct costs under the new standard. The Company plans to elect this package of practical expedients; however, the Company does not expect to elect the use of hindsight practical expedients and therefore current lease terms largely remained unchanged. The new standard also allows practical expedients for future accounting under the new standard. The Company plans to elect the short-term lease recognition exemption and will not recognize a lease obligation and right-of-use asset on its balance sheet for all leases with terms of 12 months or less. The Company also plans to elect the practical expedient to not separate lease and non-lease components for all of its leases resulting in a larger lease liability recorded on the balance sheet. The Company is still evaluating the impact of the standard on its consolidated financial statements but currently believes that the most significant effects of adoption relate to the recognition of new right-of-use assets and lease liabilities on the balance sheet for real estate operating leases. Future lease obligations are disclosed in Note 13. "Commitments and Contingencies" of the Annual Report on Form 10-K for the year ended December 31, 2017 . The Company is in the process of evaluating its policies and internal controls, as well as implementing a new lease management system which will be utilized to account for leases under the new guidance once adopted. In August 2018, the SEC issued a final rule that amends certain disclosure requirements as part of the SEC’s overall project to improve disclosure effectiveness and simplify compliance. The final rule eliminates redundant, duplicative and overlapping requirements which are substantially similar to current GAAP or other SEC disclosure requirements, as well as amends or removes outdated and superseded requirements. However, in some situations, the amendments expanded disclosure requirements, such as an analysis of changes in stockholders’ equity will now be required for the current and comparative quarter and year-to-date interim periods. The amended rules become effective 30 days after publication in the Federal Register. The Company has included its statement of changes in stockholders' equity for the three and nine month periods ended September 30, 2018 and September 30, 2017 to conform with the new requirements.

Revenue Recognition [Abstract]
Revenue from Contract with Customer [Text Block]	2. REVENUE RECOGNITION Adoption of the New Revenue Standard Effective January 1, 2018, the Company adopted the new revenue standard using the modified retrospective method. Results for reporting periods beginning after January 1, 2018 are presented under the new revenue standard; however, the comparative prior period amounts have not been restated and continue to be reported in accordance with historic accounting under ASC Topic 605. The majority of the Company's revenue continues to be recognized at the completion of a homesale transaction under the new revenue standard, however as a result of the adoption the Company recognized additional contract liabilities and deferred assets associated with certain other revenue streams. As of January 1, 2018, the Company recorded a net debit to its opening Accumulated deficit of $22 million , net of tax, due to the cumulative impact of adopting the new revenue standard, with the impact primarily related to the recognition of additional contract liabilities for initial area development fees and deferred assets for prepaid commissions. Contract Liabilities for Initial Area Development Fees ("ADF"): Contract liabilities are recorded when cash payments are received or due in advance of the Company's performance. The Company records these as deferred revenues and are classified as current or non-current liabilities in the Condensed Consolidated Balance Sheets based on the expected timing of revenue recognition. The Real Estate Franchise Services segment collects an initial ADF for international territory transactions, which are recorded as deferred revenue when received and recognized into revenue over the term of the agreement, typically 25 years, 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. ADFs were recognized as revenue upfront when received under historical guidance. Prepaid Commissions: The incremental direct costs of obtaining a contract, which primarily consist of franchise sales commissions, are deferred and amortized generally over the estimated life of the customer relationship for domestic and international contracts. The Company classifies prepaid commissions as current or non-current assets in the Condensed Consolidated Balance Sheets based on the expected timing of recognizing expense. The Real Estate Franchise Services segment recognizes a deferred asset for commissions paid to Realogy franchise sales employees upon the sale of a new franchise. The amount of commissions is calculated as a percentage of the anticipated gross commission income of the new franchisee or the amount of the ADF and is amortized on a straight-line basis over the estimated life of franchise customer relationships, 30 years for domestic franchise agreements, or the agreement term for international franchise agreements which is generally 25 years. Franchise sales commissions were expensed upfront when paid under historical guidance. Practical Expedients and Exemptions: The Company elected to apply the practical expedient that only requires the Company to apply the revenue standard to contracts that were open as of the beginning of the earliest period presented which impacted the amount of prepaid commissions capitalized. The majority of the Company's contracts are transactional in nature or have a duration of one-year or less. Accordingly, the Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. The cumulative effect of the changes made to the Condensed Consolidated Balance Sheets for the adoption of the new revenue standard were as follows: Balance Sheet accounts prior to the new revenue standard adoption adjustments Adjustments due to the adoption of the new revenue standard Balance Sheet accounts after the new revenue standard adoption adjustments ASSETS Current assets: Trade receivables $ 153 $ 1 $ 154 Other current assets 179 2 181 Total current assets 789 3 792 Other non-current assets 222 23 245 Total assets $ 7,337 $ 26 $ 7,363 LIABILITIES AND EQUITY Current liabilities: Accrued expenses and other current liabilities $ 478 $ 2 $ 480 Total current liabilities 955 2 957 Deferred income taxes 327 (8 ) 319 Other non-current liabilities 212 54 266 Total liabilities 4,715 48 4,763 Equity: Accumulated deficit (a) (2,622 ) (22 ) (2,644 ) Accumulated other comprehensive loss (a) (46 ) — (46 ) Total stockholders' equity 2,618 (22 ) 2,596 Total equity 2,622 (22 ) 2,600 Total liabilities and equity $ 7,337 $ 26 $ 7,363 _______________ (a) Beginning balances have been adjusted for the adoption of the accounting standard update on stranded tax effects related to the 2017 Tax Act which resulted in a debit to Accumulated other comprehensive loss and a credit to Accumulated deficit of $9 million . See Note 1, "Basis of Presentation" in the "Recently Adopted Accounting Pronouncements" section for additional information. The impact of adopting the new revenue standard, as compared to historic guidance under ASC Topic 605, was immaterial to the Company's Condensed Consolidated Financial Statements as of and for the nine months ended September 30, 2018 . Revenue Recognition 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 new 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 September 30, 2018 vs September 30, 2017 (e) Real Estate Company Relocation Title and Corporate and Other Total 2018 2017 2018 2017 2018 2017 2018 2017 2018 2017 2018 2017 Gross commission income (a) $ — $ — $ 1,246 $ 1,250 $ — $ — $ — $ — $ — $ — $ 1,246 $ 1,250 Service revenue (b) — — 3 1 107 110 158 150 — — 268 261 Franchise fees (c) 189 192 — — — — — — (80 ) (81 ) 109 111 Other (d) 32 32 19 16 1 1 4 4 (3 ) (1 ) 53 52 Net revenues $ 221 $ 224 $ 1,268 $ 1,267 $ 108 $ 111 $ 162 $ 154 $ (83 ) $ (82 ) $ 1,676 $ 1,674 Nine Months Ended September 30, 2018 vs September 30, 2017 (e) Real Estate Company Relocation Title and Corporate and Other Total 2018 2017 2018 2017 2018 2017 2018 2017 2018 2017 2018 2017 Gross commission income (a) $ — $ — $ 3,536 $ 3,505 $ — $ — $ — $ — $ — $ — $ 3,536 $ 3,505 Service revenue (b) — — 7 6 289 287 432 417 — — 728 710 Franchise fees (c) 531 525 — — — — — — (229 ) (229 ) 302 296 Other (d) 103 106 50 45 3 3 12 14 (9 ) (9 ) 159 159 Net revenues $ 634 $ 631 $ 3,593 $ 3,556 $ 292 $ 290 $ 444 $ 431 $ (238 ) $ (238 ) $ 4,725 $ 4,670 _______________ (a) Approximately 75% of the Company's total net revenues related to gross commission income at the Company Owned Brokerage Services segment, which is recognized at a point in time at the closing of a homesale transaction. (b) Approximately 15% of the Company's total net revenues related to service fees primarily consisting of title and escrow fees at the Title and Settlement Services segment, which are recognized at a point in time at the closing of a homesale transaction, and relocation fees at the Relocation Services segment, which are recognized as revenue when or as the related performance obligation is satisfied, which is dependent on the type of service performed. Relocation fees at the Relocation Services segment primarily include: (i) referral fees which are recognized at a point in time of the closing of a homesale transaction, (ii) outsourcing fees, which are management fees charged to clients frequently related to a bundle of relocation services performed and are recognized over the average time period to complete a move, and (iii) referral commissions from third party suppliers which are recognized at the time of the completion of the related service. (c) Approximately 5% of the Company's total net revenues related to franchise fees at the Real Estate Franchise Services segment, primarily domestic royalties, which are recognized at a point in time when the underlying franchisee revenue is earned (upon close of the homesale transaction). (d) Approximately 5% of the Company's total net revenues related to other revenue, which comprised of brand marketing funds received at the Real Estate Franchise Services segment from franchisees and other miscellaneous revenues across all of the business segments. (e) Prior period amounts have not been adjusted under the modified retrospective method. The Company's revenue streams are discussed further below by business segment: Real Estate Franchise Services The Company franchises its real estate brands to real estate brokerage businesses that are independently owned and operated. Franchise revenue principally consists of royalty and marketing fees from the Company’s franchisees. The royalty received is primarily based on a gross percentage (generally 6% ) of the franchisee’s gross commission income. Royalty fees are accrued as the underlying franchisee revenue is earned (upon close of the homesale transaction). Annual volume incentives given to certain franchisees on royalty fees are recorded as a reduction to revenue and are accrued for in relative proportion to the recognition of the underlying gross franchise revenue. Non-standard sales incentives are recorded as a reduction to revenue ratably over the related performance period or from the date of issuance through the remaining life of the related franchise agreement. Franchise revenue also includes domestic initial franchise fees which are generally non-refundable and recognized by the Company as revenue upon the execution or opening of a new franchisee office to cover the upfront costs associated with opening the franchisee for business under one of Realogy’s brands. The Company also earns marketing fees from its franchisees and utilizes such fees to fund marketing campaigns on behalf of its franchisees. As such, brand marketing fund fees are recorded as deferred revenue when received and recognized into revenue as earned when these funds are spent on marketing activities. The balance for deferred brand marketing fund fees decrease d from $13 million at January 1, 2018 to $8 million at September 30, 2018 primarily due to amounts recognized into revenue matching expenses for marketing activities, partially offset by additional fees received from franchisees during the nine months ended September 30, 2018 . The Company collects initial ADFs 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. The balance for deferred ADFs decrease d from $58 million at January 1, 2018 to $55 million at September 30, 2018 due to revenues of $4 million recognized during the nine months ended September 30, 2018 that were included in the deferred revenue balance at the beginning of the period, partially offset by $1 million of additional area development fees received during the nine months ended September 30, 2018 . In addition, the Company recognizes a deferred asset for commissions paid to Realogy franchise sales employees upon the sale of a new franchise as these are considered costs of obtaining a contract with a customer that are expected to provide benefits to the Company for longer than one year. The amount of commissions is calculated as a percentage of the anticipated gross commission income of the new franchisee or ADF and is amortized over 30 years for domestic franchise agreements or the agreement term for international franchise agreements (generally 25 years). The amount of prepaid commissions was $24 million at both January 1, 2018 and September 30, 2018 . Company Owned Real Estate Brokerage Services As an owner-operator of real estate brokerages, the Company assists home buyers and sellers in listing, marketing, selling and finding homes. Real estate commissions earned by the Company’s real estate brokerage business are recorded as revenue at a point in time which is upon the closing of a real estate transaction (i.e., purchase or sale of a home). These revenues are referred to as gross commission income. The commissions the Company pays to real estate agents are recognized concurrently with associated revenues and presented as the commission and other agent-related costs line item on the accompanying Condensed Consolidated Statements of Operations. The Company has relationships with developers, primarily in major cities, to provide marketing and brokerage services in new developments. New development closings generally have a development period of between 18 and 24 months from contracted date to closing. In some cases, the Company receives advanced commissions which are recorded as deferred revenue when received and recognized as revenue when the new development closes. The balance of advanced commissions related to developments was a liability of $10 million at both January 1, 2018 and September 30, 2018 . During the nine months ended September 30, 2018 , the balance increased $5 million related to additional commissions received for new developments, offset by a $5 million decrease due to revenues recognized on units closed. Relocation Services The Company provides relocation services to corporate and government clients for the transfer of their employees ("transferees"). Such services include homesale assistance including the purchasing and/or selling of a transferee’s home and providing home equity advances to transferees (generally guaranteed by the individual's employer), arranging household goods moving services, and other relocation services such as expense processing, relocation policy counseling, relocation-related accounting, coordinating visa and immigration support, intercultural and language training and destination services. In the majority of relocation transactions, the gain or loss on the sale of a transferee’s home is generally borne by the individual's employer. C lients may pay an outsourcing management fee that can cover several of the relocation services listed above, according to the clients' specific needs. In addition, the Company provides home buying and selling assistance to members of Affinity organizations. The Company earns referral commission revenue primarily from real estate brokers for the home sale and purchase for transferees a nd Affinity members, which is recognized at a point in time when the underlying property closes, and revenues from other third-party service providers where the Company earns a referral commission, which is recognized at the point in time at the completion of services. Furthermore, the Company generally earns interest income on the funds it advances on behalf of the transferring employee, which is recorded within other revenue (as is the corresponding interest expense on the securitization obligations) in the accompanying Condensed Consolidated Statements of Operations. The Company earns revenues from outsourcing management fees charged to clients for the performance and facilitation of relocation services. 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. The balance for outsourcing management fees was a liability of $5 million at both January 1, 2018 and September 30, 2018 . During the nine months ended September 30, 2018 , the balance increased $48 million primarily related to additions due to new management fees billed on new relocation files in advance of the Company satisfying its performance obligation, offset by a $48 million decrease as a result of revenues recognized as the performance obligations were satisfied. The Relocation Services segment manages the Cartus Broker Network, which is a network of real estate brokers consisting of our company owned brokerage operations, select franchisees and independent real estate brokers who have been approved to become members. Network fees are billed in the fourth quarter of the previous year for the following year's membership and recognized into revenue on a straight-line basis each month during the membership period. The balance for Cartus Broker Membership decrease d from $8 million at January 1, 2018 to $3 million at September 30, 2018 primarily due to $7 million of revenues recognized during the nine months ended September 30, 2018 that were included in the deferred revenue balance at the beginning of the period, partially offset by a $2 million increase related to new network fees. Title and Settlement Services The Company provides title and closing services, which include title search procedures for title insurance policies, homesale escrow and other closing services. Title revenues and title and closing service fees are recorded at a point in time which occurs at the time a homesale transaction or refinancing closes. The Company also owns an underwriter of title insurance. For unaffiliated agents, the underwriter recognizes policy premium revenue on a gross basis (before deduction of agent commission) upon notice of policy issuance from the agent. For affiliated title agents, the underwriter recognizes the incremental policy premium revenue upon the effective date of the title policy as the agent commission revenue is already recognized by the affiliated title agent. Contract Balances (Deferred Revenue) The following table shows the change in the Company's contract liabilities related to revenue contracts by reportable segment for the period: Nine Months Ended September 30, 2018 Beginning Balance at January 1, 2018 Additions during the period Recognized as Revenue during the period Ending Balance at September 30, 2018 Real Estate Franchise Services (a) $ 79 $ 88 $ (93 ) $ 74 Company Owned Real Estate Brokerage Services 17 12 (14 ) 15 Relocation Services 18 66 (71 ) 13 Total $ 114 $ 166 $ (178 ) $ 102 _______________ (a) Revenues recognized include intercompany marketing fees paid by the Company Owned Real Estate Brokerage Services segment.

Maturities Table As of September 30, 2018 , the combined aggregate amount of maturities for long-term borrowings, excluding securitization obligations, for the remainder of 2018 and each of the next four years is as follows: Year Amount Remaining 2018 (a) $ 257 2019 480 2020 44 2021 612 2022 81 _______________ (a) Remaining 2018 includes amortization payments totaling $4 million and $3 million for the Term Loan A and Term Loan B facilities, respectively, as well as $250 million of revolver borrowings under the Revolving Credit Facility which expires in February 2023 but is classified on the balance sheet as current due to the revolving nature of the facility. The current portion of long term debt of $727 million shown on the condensed consolidated balance sheet consists of $447 million of 4.50% Senior Notes due April 2019, four quarters of amortization payments totaling $19 million and $11 million for the Term Loan A and Term Loan B facilities, respectively, and $250 million of revolver borrowings under the Revolving Credit Facility. The Company is evaluating different alternatives to repay the 4.50% Senior Notes due in April 2019 including refinancing or using existing available liquidity. Senior Secured Credit Facility In February 2018, the Company entered into fifth and sixth amendments to the Amended and Restated Senior Secured 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") that respectively (i) replaced the approximately $1,100 million Term Loan B due July 2022 with a new $1,080 million Term Loan B due February 2025 and (ii) increased the borrowing capacity under its Revolving Credit Facility to $1,400 million from the prior $1,050 million and extended the maturity date to February 2023 from October 2020. The Senior Secured Credit Agreement provides for: (a) the Term Loan B issued in the original aggregate principal amount of $1,080 million with a maturity date of February 2025. The Term Loan B 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 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 $1,400 million Revolving Credit Facility with a maturity date of February 2023, which includes a $125 million letter of credit subfacility. 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 Senior Secured Credit Agreement permits the Company to obtain up to $500 million of additional credit facilities from lenders reasonably satisfactory to the administrative agent and us, without the consent of the existing lenders under the new senior secured credit facility, plus an unlimited amount if Realogy Group's senior secured leverage ratio is less than 3.50 to 1.00 on a pro forma basis. Subject to certain restrictions, the Senior Secured Credit Agreement also permits us to issue senior secured or unsecured notes in lieu of any incremental facility. 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. Realogy Group’s Senior Secured Credit Agreement contains financial, affirmative and negative covenants and requires Realogy Group to maintain (so long as the Revolving Credit Facility is outstanding) a 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 revolver at the testing date. Total senior secured net debt does not include unsecured indebtedness, including the Unsecured Notes as well as the securitization obligations. At September 30, 2018 , Realogy Group was in compliance with the senior secured leverage ratio covenant. Term Loan A Facility In February 2018, Realogy Group entered into a second amendment to the Term Loan A senior secured credit agreement. Under the amendment, the Company aggregated the existing $435 million Term Loan A and $355 million Term Loan A-1 tranches due October 2020 and July 2021, respectively, into a new single tranche of $750 million Term Loan A due February 2023. The Term Loan A provides for quarterly amortization payments totaling per annum 2.5% , 2.5% , 5.0% , 7.5% and 10.0% of the original principal amount of the Term Loan A, which commence on June 30, 2018 and continue through February 8, 2023. The interest rates with respect to the Term Loan A are based on, at our 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% Consistent with the Senior Secured Credit Agreement, the Term Loan A Facility permits the Company to obtain up to $500 million of additional credit facilities from lenders reasonably satisfactory to the administrative agent and the Company, without the consent of the existing lenders under the Term Loan A, plus an unlimited amount if the Company's senior secured leverage ratio is less than 3.50 to 1.00 on a pro forma basis. Subject to certain restrictions, the Term Loan A Facility also permits us to issue senior secured or unsecured notes in lieu of any incremental facility. Unsecured Notes The 4.50% Senior Notes, 5.25% Senior Notes and 4.875% Senior Notes (collectively the "Unsecured Notes") are unsecured senior obligations of Realogy Group that mature on April 15, 2019, December 1, 2021 and June 1, 2023, respectively. Interest on the Unsecured Notes is payable each year semiannually on April 15 and October 15 for the 4.50% Senior Notes and June 1 and December 1 for both the 5.25% Senior Notes and 4.875% Senior Notes. 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 and Realogy Group's outstanding debt securities and are guaranteed by Realogy Holdings on an unsecured senior subordinated basis. The indentures governing the Unsecured Notes contain affirmative and negative covenants of Realogy Group and the subsidiary guarantors. Other Debt Facilities The Company has an Unsecured Letter of Credit Facility to provide for the issuance of letters of credit required for general corporate purposes by the Company. At September 30, 2018 , the capacity of the facility was $66 million , which expires in December 2019. At December 31, 2017, the capacity was $74 million , however $8 million of capacity under the facility expired in September 2018. As of September 30, 2018 and December 31, 2017 , the Company utilized $64 million and $69 million of the capacity, respectively. The fixed pricing to the Company is based on a spread above the credit default swap rate for senior unsecured debt obligations of the Company over the applicable letter of credit period. Realogy Group's obligations under the Unsecured Letter of Credit Facility are guaranteed on an unsecured senior basis by each domestic subsidiary of Realogy Group that is a guarantor under the Senior Secured Credit Facility and Realogy Group's outstanding debt securities. Securitization Obligations Realogy Group has secured obligations through Apple Ridge Funding LLC under a securitization program. As of September 30, 2018 , the Company utilized the full borrowing capacity of $250 million under the Apple Ridge Funding LLC securitization program. 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 2018, Realogy Group extended the existing Cartus Financing Limited securitization program to August 2019. As of September 30, 2018 , there were $14 million of outstanding borrowings on the facilities. 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 Facility and the indentures governing the Unsecured 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 business 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 our relocation business. Certain of the funds that Realogy Group receives from relocation receivables and related assets must be utilized to repay securitization obligations. These obligations were collateralized by $336 million and $218 million of underlying relocation receivables and other related relocation assets at September 30, 2018 and December 31, 2017 , 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 Condensed Consolidated Balance Sheets. Interest incurred in connection with borrowings under these facilities amounted to $2 million for both the three months ended September 30, 2018 and 2017 , and $6 million and $5 million for the nine months ended September 30, 2018 and 2017 , 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 business where interest is generally earned on such assets. These securitization obligations represent floating rate debt for which the average weighted interest rate was 3.7% and 3.3% for the nine months ended September 30, 2018 and 2017 , respectively. Loss on the Early Extinguishment of Debt and Write-Off of Financing Costs As a result of the refinancing transactions in February 2018, the Company recorded a loss on the early extinguishment of debt of $7 million and wrote off financing costs of $2 million to interest expense during the first nine months of 2018 . As a result of the refinancing transaction in January 2017 and a reduction of the Unsecured Letter of Credit Facility in September of 2017, the Company recorded losses on the early extinguishment of debt of $5 million during the nine months ended September 30, 2017 .

The only difference between Realogy Group and Realogy Holdings is that the $1 million in par value of common stock in Realogy Holdings' equity is included in additional paid in capital in Realogy Groups' equity. Stock Repurchases The Company may repurchase shares of its common stock under authorizations from its Board of Directors. Shares repurchased are retired and not displayed separately as treasury stock on the consolidated financial statements. The par value of the shares repurchased and retired is deducted from common stock and the excess of the purchase price over par value is first charged against any available additional paid-in capital with the balance charged to retained earnings. Direct costs incurred to repurchase the shares are included in the total cost of the shares. The Company's Board of Directors authorized a share repurchase program of up to $275 million , $300 million and $350 million of the Company's common stock in February 2016, 2017 and 2018, respectively. In the third quarter of 2018 , the Company repurchased and retired 4.7 million shares of common stock for $102 million at a weighted average market price of $21.37 per share. For the nine months ended September 30, 2018 , the Company repurchased and retired 12.5 million shares of common stock for $302 million at a weighted average market price of $24.07 per share. As of September 30, 2018 , the Company had repurchased and retired 29 million shares of common stock for an aggregate of $776 million at a total weighted average market price of $26.74 per share. As of September 30, 2018 , $149 million remained available for repurchase under the February 2018 share repurchase program. Stock-Based Compensation During the first quarter of 2018 , the Company granted 0.4 million shares of non-qualified stock options with a weighted exercise price of $25.35 and 1.1 million shares of restricted stock units ("RSUs") with a weighted average grant date fair value of $25.45 . On May 2, 2018, the Company granted RSUs and PSUs aggregating 0.8 million shares, which were approved by the Company's Board of Directors on March 1, 2018 but subject to approval of the 2018 LTIP at the 2018 Annual Meeting of Stockholders held on May 2, 2018, with a weighted average grant date fair value of $25.04 . Dividend Policy In August 2016, the Company’s Board of Directors approved the initiation of a quarterly cash dividend policy of $0.09 per share on its common stock. The Board declared and paid a quarterly cash dividend of $0.09 per share on the Company’s common stock during the first, second and third quarters of 2018 . The declaration and payment of any future dividend will be subject to the discretion of the Board of Directors and will depend on a variety of factors, including the Company’s financial condition and results of operations, contractual restrictions, including restrictive covenants contained in the Company’s credit agreements, and the indentures governing the Company’s outstanding debt securities, capital requirements and other factors that the Board of Directors deems relevant. Pursuant to the Company’s policy, dividends payable in cash are treated as a reduction of additional paid-in capital since the Company is currently in an accumulated deficit position.

Earnings Per Share [Abstract]
Earnings Per Share	. EARNINGS PER SHARE Earnings per share attributable to Realogy Holdings Basic earnings per share is computed based on net income attributable to Realogy Holdings stockholders divided by the basic weighted-average shares outstanding during the period. Dilutive earnings 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. Three Months Ended September 30, Nine Months Ended September 30, (in millions, except per share data) 2018 2017 2018 2017 Net income attributable to Realogy Holdings shareholders $ 103 $ 95 $ 159 $ 176 Basic weighted average shares 122.7 136.1 126.5 137.8 Stock options, restricted stock units and performance share units (a) 0.9 2.0 1.1 1.6 Weighted average diluted shares 123.6 138.1 127.6 139.4 Earnings Per Share: Basic $ 0.84 $ 0.70 $ 1.26 $ 1.28 Diluted $ 0.83 $ 0.69 $ 1.25 $ 1.26 _______________ (a) The three and nine months ended September 30, 2018 , respectively exclude 7.4 million and 7.2 million shares of common stock issuable for incentive equity awards, which includes performance share units based on the achievement of target amounts, that are anti-dilutive to the diluted earnings per share computation. The three and nine months ended September 30, 2017 , respectively, exclude 4.9 million and 5.3 million shares of common stock issuable for incentive equity awards, which includes performance share units based on the achievement of target amounts, that are anti-dilutive to the diluted earnings per share computation. In the third quarter of 2018 , the Company repurchased and retired 4.7 million shares of common stock for $102 million at a weighted average market price of $21.37 per share. For the nine months ended September 30, 2018 , the Company repurchased and retired 12.5 million shares of common stock for $302 million at a weighted average market price of $24.07 per share. The purchase of shares under this plan reduces the weighted-average number of shares outstanding in the basic earnings per share calculation.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Litigation The Company is involved in claims, legal proceedings, alternative dispute resolution and governmental inquiries related to alleged contract disputes, business practices, intellectual property and other commercial, employment, regulatory and tax matters. Examples of such matters include but are not limited to allegations: • that residential real estate sales agents engaged by NRT—under certain state or federal laws—are potentially employees instead of independent contractors, and they or regulators therefore may bring claims against NRT 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; • concerning other employment law matters, including wage and hour 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 claims for alleged RESPA or state real estate law violations; • 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 copyright law, including infringement actions alleging improper use of copyrighted photographs on websites or in marketing materials without consent of the copyright holder; • concerning claims generally against the title company contending that, as the escrow company, the company knew or should have known that a transaction was fraudulent or concerning other title defects or settlement errors; • concerning information security and cyber-crime, including claims under new and emerging data privacy laws related to the protection of customer, employee or third-party information, as well as those related to the diversion of homesale transaction closing funds; • concerning anti-trust and anti-competition matters; and • those related to general fraud claims. Real Estate Business Litigation Dodge, et al. v. PHH Corporation, et al., formerly captioned Strader, et al. and Hall v. PHH Corporation, et al. (U.S. District Court for the Central District of California). This is a purported class action brought by four California residents against 15 defendants, including Realogy and certain of its subsidiaries, PHH Corporation and PHH Home Loans, LLC (a joint venture between Realogy and PHH), alleging violations of Section 8(a) of RESPA. On May 19, 2017, the parties held a mediation session, at which they agreed in principle to a settlement of the action, pursuant to which the Company would pay approximately $8 million (or one-half of the settlement). In settling the matter, the Company specifically denied any wrongdoing with respect to the claims asserted in the case. As a result of the settlement, the Company accrued $8 million in the second quarter of 2017 and the liability is included in accrued expenses and other current liabilities on the Condensed Consolidated Balance Sheets. The Court granted final approval of the settlement effective as of August 27, 2018. The Company is involved in certain other claims and legal actions arising in the ordinary course of our business. Such litigation, regulatory actions and other proceedings may include, but are not limited to, actions relating to intellectual property, commercial arrangements, franchising arrangements, the fiduciary duties of brokers, actions against our title company alleging it knew or should have known that others were committing mortgage fraud, 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, antitrust and anti-competition claims, general fraud claims (including wire fraud associated with third-party diversion of funds from a brokerage transaction), employment law claims, including claims challenging the classification of our sales agents as independent contractors, wage and hour classification claims and claims alleging violations of RESPA or state consumer fraud statutes. 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. * * * 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 $18 million at both September 30, 2018 and December 31, 2017 , respectively. The due to former parent balance was comprised of the Company’s portion of the following: (i) Cendant’s remaining state and foreign contingent tax liabilities, (ii) accrued interest on contingent tax liabilities, (iii) potential liabilities related to Cendant’s terminated or divested businesses, and (iv) 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 $538 million at September 30, 2018 and $469 million at December 31, 2017 . These escrow and trust deposits are not assets of the Company and, therefore, are excluded from the accompanying Condensed Consolidated Balance Sheets. However, the Company remains contingently liable for the disposition of these deposits.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION The reportable segments presented below represent the Company’s operating 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 operating 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, losses on the early extinguishment of debt, asset 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.
Equity Method Investments, Policy	Equity Method Investments At September 30, 2018 and December 31, 2017 , the Company had various equity method investments aggregating $53 million and $74 million , respectively, which are recorded within other non-current assets on the accompanying Condensed Consolidated Balance Sheets. The $53 million investment balance at September 30, 2018 included $46 million for the Company's investment in Guaranteed Rate Affinity, LLC ("Guaranteed Rate Affinity"). The Company's interest in PHH Home Loans, LLC ("PHH Home Loans") was sold to a subsidiary of PHH Corporation in the first quarter of 2018. The $74 million investment balance at December 31, 2017 included $48 million for the Company's investment in Guaranteed Rate Affinity and $19 million for the Company's remaining investment in PHH Home Loans. The Company received net cash proceeds of $19 million reducing the investment balance in PHH Home Loans to zero in the first quarter of 2018. For the three and nine months ended September 30, 2018 , the Company recorded equity losses of $1 million and $3 million , respectively, at the Title and Settlement Services segment primarily related to costs associated with the ramp up of operations of Guaranteed Rate Affinity. The Company recorded $10 million and $7 million of earnings related to its equity investments for the three and nine months ended September 30, 2017 , respectively, primarily related to earnings from the first two phases of the sale of PHH Home Loans' assets to Guaranteed Rate Affinity, partially offset by the recognition of certain exit costs at PHH Home Loans. The Company received $3 million and $24 million in cash dividends from equity method investments during the nine months ended September 30, 2018 and 2017 , respectively. The Company invested $4 million into Guaranteed Rate Affinity during the first quarter of 2018 and $34 million into Guaranteed Rate Affinity during the nine months ended September 30, 2017 .
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 $40 million and $67 million for the three months ended September 30, 2018 and 2017 , respectively, and an expense of $73 million and $131 million for the nine months ended September 30, 2018 and 2017 , respectively.
Derivatives, Policy	Derivative Instruments The Company records derivatives and hedging activities on the balance sheet at their respective fair values. The Company uses foreign currency forward contracts largely to manage its exposure to changes in foreign currency exchange rates associated with its foreign currency denominated receivables and payables. The Company primarily manages its foreign currency exposure to the Euro, British Pound, Swiss Franc and Canadian Dollar. The Company has not elected to utilize hedge accounting for these forward contracts; therefore, any change in fair value is recorded in the Condensed Consolidated Statements of Operations. However, the fluctuations in the value of these forward contracts generally offset the impact of changes in the value of the underlying risk that they are intended to economically hedge. As of September 30, 2018 , the Company had outstanding foreign currency forward contracts in an asset position with a fair value of less than $1 million and a notional value of $27 million . As of December 31, 2017 , the Company had outstanding foreign currency forward contracts in a liability position with a fair value of less than $1 million and a notional value of $25 million . The Company also enters into interest rate swaps to manage its exposure to changes in interest rates associated with its variable rate borrowings. Interest rate swaps with a notional value of $425 million expired February 10, 2018. As of September 30, 2018 , the Company had interest rate swaps with an aggregate notional value of $1,600 million to offset the variability in cash flows resulting from the term loan facilities as follows: Notional Value (in millions) Commencement Date Expiration Date $600 August 2015 August 2020 $450 November 2017 November 2022 $400 (a) August 2020 August 2025 $150 (a) November 2022 November 2027 _______________ (a) During the second quarter of 2018, the Company entered into four new forward starting interest rate swaps, two with a notional value of $125 million and two with a notional value of $150 million . 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, 2018 December 31, 2017 Interest rate swap contracts Other non-current assets $ 15 $ — Other current and non-current liabilities 2 13 The effect of derivative instruments on earnings was as follows: Derivative Instruments Not Designated as Hedging Instruments Location of (Gain) or Loss Recognized for Derivative Instruments (Gain) or Loss Recognized on Derivatives Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 Interest rate swap contracts Interest expense $ (7 ) $ — $ (19 ) $ 4 Foreign exchange contracts Operating expense — 1 (1 ) 2
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 $11 million and $7 million at September 30, 2018 and December 31, 2017 , respectively.
New Accounting Pronouncements, Policy	Recently Adopted Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (Topic 606) " Revenue from Contracts with Customers " (the "new revenue standard"). The objective of the new revenue standard is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries, and across capital markets. After a review of the Company's revenue streams, the Company determined that the new revenue standard did not have a material impact on financial results as the majority of the Company's revenue is recognized at the completion of a homesale transaction which did not result in a change in the timing of recognition of revenue transactions under the new revenue standard. The Company adopted the new revenue standard on January 1, 2018 using the modified retrospective transition method in which the cumulative effect of applying the new revenue standard was recognized as an adjustment to the opening balance of retained earnings. See Note 2, "Revenue Recognition" for further details. In February 2018, the FASB issued a new standard which permits companies to reclassify certain income tax effects resulting from the 2017 Tax Act, called "stranded tax effects", from accumulated other comprehensive income ("AOCI") to retained earnings. According to the new guidance, the reclassification amount should include the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances, if any, at the date of enactment of the 2017 Tax Act related to items remaining in AOCI. The guidance is effective for all companies for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption is permitted. The Company early adopted this standard in the first quarter of 2018 which resulted in a debit to Accumulated other comprehensive loss and a credit to Accumulated deficit for $9 million . The Company’s accounting policy for releasing income tax effects from AOCI is to release those effects when our entire portfolio of the type of item is liquidated. In June 2018, the FASB issued a new standard related to non-employee share-based payment accounting. The new guidance eliminates specific accounting for non-employee share-based payments and aligns the treatment for awards issued to employees and non-employees reducing the complexity of measurement of non-employee awards and creating a single accounting model. The new standard is applied to all new awards granted after the date of adoption. In addition, all liability-classified awards that have not been settled and equity-classified awards for which a measurement date has not been established by the adoption date should be remeasured at fair value as of the adoption date with a cumulative effect adjustment to opening retained earnings in the fiscal year of adoption. If early adoption of the new guidance is chosen in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The Company elected to early adopt this guidance during the second quarter of 2018. There was an immaterial impact upon adoption. Recently Issued Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates ("ASUs"). ASUs not listed below 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. In February 2016, the FASB issued its new standard on leases which requires virtually all leases to be recognized on the balance sheet. Lessees will recognize a right-of-use asset and a lease liability for all leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for lease incentives, prepayments and initial direct costs. For income statement purposes, leases will be classified as either operating or finance leases. Operating leases will result in straight-line expense, similar to current operating leases, while finance leases will result in a front-loaded expense pattern, similar to current capital leases. Classification will be based on criteria that are largely similar to those applied in current lease accounting, but without explicit bright lines. The new standard is effective on January 1, 2019, with early adoption permitted, requiring a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial application. In July 2018, the FASB issued an ASU that allows entities to elect an optional transition relief giving companies the option to apply the provisions of the new guidance at the effective date (e.g., January 1, 2019), as opposed to the earliest comparative period presented in the financial statements under the modified retrospective transition approach (January 1, 2017), and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company will adopt the new standard during the first quarter of 2019 and will elect the optional transition relief. The new standard allows for an optional package of practical expedients during transition which permit companies to not reassess prior conclusions about lease identification, lease classification and initial direct costs under the new standard. The Company plans to elect this package of practical expedients; however, the Company does not expect to elect the use of hindsight practical expedients and therefore current lease terms largely remained unchanged. The new standard also allows practical expedients for future accounting under the new standard. The Company plans to elect the short-term lease recognition exemption and will not recognize a lease obligation and right-of-use asset on its balance sheet for all leases with terms of 12 months or less. The Company also plans to elect the practical expedient to not separate lease and non-lease components for all of its leases resulting in a larger lease liability recorded on the balance sheet. The Company is still evaluating the impact of the standard on its consolidated financial statements but currently believes that the most significant effects of adoption relate to the recognition of new right-of-use assets and lease liabilities on the balance sheet for real estate operating leases. Future lease obligations are disclosed in Note 13. "Commitments and Contingencies" of the Annual Report on Form 10-K for the year ended December 31, 2017 . The Company is in the process of evaluating its policies and internal controls, as well as implementing a new lease management system which will be utilized to account for leases under the new guidance once adopted. In August 2018, the SEC issued a final rule that amends certain disclosure requirements as part of the SEC’s overall project to improve disclosure effectiveness and simplify compliance. The final rule eliminates redundant, duplicative and overlapping requirements which are substantially similar to current GAAP or other SEC disclosure requirements, as well as amends or removes outdated and superseded requirements. However, in some situations, the amendments expanded disclosure requirements, such as an analysis of changes in stockholders’ equity will now be required for the current and comparative quarter and year-to-date interim periods. The amended rules become effective 30 days after publication in the Federal Register. The Company has included its statement of changes in stockholders' equity for the three and nine month periods ended September 30, 2018 and September 30, 2017 to conform with the new requirements.

Revenue Recognition [Abstract]
Revenue Recognition, Policy	Revenue Recognition 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 new 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 September 30, 2018 vs September 30, 2017 (e) Real Estate Company Relocation Title and Corporate and Other Total 2018 2017 2018 2017 2018 2017 2018 2017 2018 2017 2018 2017 Gross commission income (a) $ — $ — $ 1,246 $ 1,250 $ — $ — $ — $ — $ — $ — $ 1,246 $ 1,250 Service revenue (b) — — 3 1 107 110 158 150 — — 268 261 Franchise fees (c) 189 192 — — — — — — (80 ) (81 ) 109 111 Other (d) 32 32 19 16 1 1 4 4 (3 ) (1 ) 53 52 Net revenues $ 221 $ 224 $ 1,268 $ 1,267 $ 108 $ 111 $ 162 $ 154 $ (83 ) $ (82 ) $ 1,676 $ 1,674 Nine Months Ended September 30, 2018 vs September 30, 2017 (e) Real Estate Company Relocation Title and Corporate and Other Total 2018 2017 2018 2017 2018 2017 2018 2017 2018 2017 2018 2017 Gross commission income (a) $ — $ — $ 3,536 $ 3,505 $ — $ — $ — $ — $ — $ — $ 3,536 $ 3,505 Service revenue (b) — — 7 6 289 287 432 417 — — 728 710 Franchise fees (c) 531 525 — — — — — — (229 ) (229 ) 302 296 Other (d) 103 106 50 45 3 3 12 14 (9 ) (9 ) 159 159 Net revenues $ 634 $ 631 $ 3,593 $ 3,556 $ 292 $ 290 $ 444 $ 431 $ (238 ) $ (238 ) $ 4,725 $ 4,670 _______________ (a) Approximately 75% of the Company's total net revenues related to gross commission income at the Company Owned Brokerage Services segment, which is recognized at a point in time at the closing of a homesale transaction. (b) Approximately 15% of the Company's total net revenues related to service fees primarily consisting of title and escrow fees at the Title and Settlement Services segment, which are recognized at a point in time at the closing of a homesale transaction, and relocation fees at the Relocation Services segment, which are recognized as revenue when or as the related performance obligation is satisfied, which is dependent on the type of service performed. Relocation fees at the Relocation Services segment primarily include: (i) referral fees which are recognized at a point in time of the closing of a homesale transaction, (ii) outsourcing fees, which are management fees charged to clients frequently related to a bundle of relocation services performed and are recognized over the average time period to complete a move, and (iii) referral commissions from third party suppliers which are recognized at the time of the completion of the related service. (c) Approximately 5% of the Company's total net revenues related to franchise fees at the Real Estate Franchise Services segment, primarily domestic royalties, which are recognized at a point in time when the underlying franchisee revenue is earned (upon close of the homesale transaction). (d) Approximately 5% of the Company's total net revenues related to other revenue, which comprised of brand marketing funds received at the Real Estate Franchise Services segment from franchisees and other miscellaneous revenues across all of the business segments. (e) Prior period amounts have not been adjusted under the modified retrospective method. The Company's revenue streams are discussed further below by business segment: Real Estate Franchise Services The Company franchises its real estate brands to real estate brokerage businesses that are independently owned and operated. Franchise revenue principally consists of royalty and marketing fees from the Company’s franchisees. The royalty received is primarily based on a gross percentage (generally 6% ) of the franchisee’s gross commission income. Royalty fees are accrued as the underlying franchisee revenue is earned (upon close of the homesale transaction). Annual volume incentives given to certain franchisees on royalty fees are recorded as a reduction to revenue and are accrued for in relative proportion to the recognition of the underlying gross franchise revenue. Non-standard sales incentives are recorded as a reduction to revenue ratably over the related performance period or from the date of issuance through the remaining life of the related franchise agreement. Franchise revenue also includes domestic initial franchise fees which are generally non-refundable and recognized by the Company as revenue upon the execution or opening of a new franchisee office to cover the upfront costs associated with opening the franchisee for business under one of Realogy’s brands. The Company also earns marketing fees from its franchisees and utilizes such fees to fund marketing campaigns on behalf of its franchisees. As such, brand marketing fund fees are recorded as deferred revenue when received and recognized into revenue as earned when these funds are spent on marketing activities. The balance for deferred brand marketing fund fees decrease d from $13 million at January 1, 2018 to $8 million at September 30, 2018 primarily due to amounts recognized into revenue matching expenses for marketing activities, partially offset by additional fees received from franchisees during the nine months ended September 30, 2018 . The Company collects initial ADFs 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. The balance for deferred ADFs decrease d from $58 million at January 1, 2018 to $55 million at September 30, 2018 due to revenues of $4 million recognized during the nine months ended September 30, 2018 that were included in the deferred revenue balance at the beginning of the period, partially offset by $1 million of additional area development fees received during the nine months ended September 30, 2018 . In addition, the Company recognizes a deferred asset for commissions paid to Realogy franchise sales employees upon the sale of a new franchise as these are considered costs of obtaining a contract with a customer that are expected to provide benefits to the Company for longer than one year. The amount of commissions is calculated as a percentage of the anticipated gross commission income of the new franchisee or ADF and is amortized over 30 years for domestic franchise agreements or the agreement term for international franchise agreements (generally 25 years). The amount of prepaid commissions was $24 million at both January 1, 2018 and September 30, 2018 . Company Owned Real Estate Brokerage Services As an owner-operator of real estate brokerages, the Company assists home buyers and sellers in listing, marketing, selling and finding homes. Real estate commissions earned by the Company’s real estate brokerage business are recorded as revenue at a point in time which is upon the closing of a real estate transaction (i.e., purchase or sale of a home). These revenues are referred to as gross commission income. The commissions the Company pays to real estate agents are recognized concurrently with associated revenues and presented as the commission and other agent-related costs line item on the accompanying Condensed Consolidated Statements of Operations. The Company has relationships with developers, primarily in major cities, to provide marketing and brokerage services in new developments. New development closings generally have a development period of between 18 and 24 months from contracted date to closing. In some cases, the Company receives advanced commissions which are recorded as deferred revenue when received and recognized as revenue when the new development closes. The balance of advanced commissions related to developments was a liability of $10 million at both January 1, 2018 and September 30, 2018 . During the nine months ended September 30, 2018 , the balance increased $5 million related to additional commissions received for new developments, offset by a $5 million decrease due to revenues recognized on units closed. Relocation Services The Company provides relocation services to corporate and government clients for the transfer of their employees ("transferees"). Such services include homesale assistance including the purchasing and/or selling of a transferee’s home and providing home equity advances to transferees (generally guaranteed by the individual's employer), arranging household goods moving services, and other relocation services such as expense processing, relocation policy counseling, relocation-related accounting, coordinating visa and immigration support, intercultural and language training and destination services. In the majority of relocation transactions, the gain or loss on the sale of a transferee’s home is generally borne by the individual's employer. C lients may pay an outsourcing management fee that can cover several of the relocation services listed above, according to the clients' specific needs. In addition, the Company provides home buying and selling assistance to members of Affinity organizations. The Company earns referral commission revenue primarily from real estate brokers for the home sale and purchase for transferees a nd Affinity members, which is recognized at a point in time when the underlying property closes, and revenues from other third-party service providers where the Company earns a referral commission, which is recognized at the point in time at the completion of services. Furthermore, the Company generally earns interest income on the funds it advances on behalf of the transferring employee, which is recorded within other revenue (as is the corresponding interest expense on the securitization obligations) in the accompanying Condensed Consolidated Statements of Operations. The Company earns revenues from outsourcing management fees charged to clients for the performance and facilitation of relocation services. 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. The balance for outsourcing management fees was a liability of $5 million at both January 1, 2018 and September 30, 2018 . During the nine months ended September 30, 2018 , the balance increased $48 million primarily related to additions due to new management fees billed on new relocation files in advance of the Company satisfying its performance obligation, offset by a $48 million decrease as a result of revenues recognized as the performance obligations were satisfied. The Relocation Services segment manages the Cartus Broker Network, which is a network of real estate brokers consisting of our company owned brokerage operations, select franchisees and independent real estate brokers who have been approved to become members. Network fees are billed in the fourth quarter of the previous year for the following year's membership and recognized into revenue on a straight-line basis each month during the membership period. The balance for Cartus Broker Membership decrease d from $8 million at January 1, 2018 to $3 million at September 30, 2018 primarily due to $7 million of revenues recognized during the nine months ended September 30, 2018 that were included in the deferred revenue balance at the beginning of the period, partially offset by a $2 million increase related to new network fees. Title and Settlement Services The Company provides title and closing services, which include title search procedures for title insurance policies, homesale escrow and other closing services. Title revenues and title and closing service fees are recorded at a point in time which occurs at the time a homesale transaction or refinancing closes. The Company also owns an underwriter of title insurance. For unaffiliated agents, the underwriter recognizes policy premium revenue on a gross basis (before deduction of agent commission) upon notice of policy issuance from the agent. For affiliated title agents, the underwriter recognizes the incremental policy premium revenue upon the effective date of the title policy as the agent commission revenue is already recognized by the affiliated title agent. Contract Balances (Deferred Revenue) The following table shows the change in the Company's contract liabilities related to revenue contracts by reportable segment for the period: Nine Months Ended September 30, 2018 Beginning Balance at January 1, 2018 Additions during the period Recognized as Revenue during the period Ending Balance at September 30, 2018 Real Estate Franchise Services (a) $ 79 $ 88 $ (93 ) $ 74 Company Owned Real Estate Brokerage Services 17 12 (14 ) 15 Relocation Services 18 66 (71 ) 13 Total $ 114 $ 166 $ (178 ) $ 102 _______________ (a) Revenues recognized include intercompany marketing fees paid by the Company Owned Real Estate Brokerage Services segment.

Shares repurchased are retired and not displayed separately as treasury stock on the consolidated financial statements. The par value of the shares repurchased and retired is deducted from common stock and the excess of the purchase price over par value is first charged against any available additional paid-in capital with the balance charged to retained earnings. Direct costs incurred to repurchase the shares are included in the total cost of the shares. The Company's Board of Directors authorized a share repurchase program of up to $275 million , $300 million and $350 million of the Company's common stock in February 2016, 2017 and 2018, respectively. In the third quarter of 2018 , the Company repurchased and retired 4.7 million shares of common stock for $102 million at a weighted average market price of $21.37 per share.

The Board declared and paid a quarterly cash dividend of $0.09 per share on the Company’s common stock during the first, second and third quarters of 2018 . The declaration and payment of any future dividend will be subject to the discretion of the Board of Directors and will depend on a variety of factors, including the Company’s financial condition and results of operations, contractual restrictions, including restrictive covenants contained in the Company’s credit agreements, and the indentures governing the Company’s outstanding debt securities, capital requirements and other factors that the Board of Directors deems relevant. Pursuant to the Company’s policy, dividends payable in cash are treated as a reduction of additional paid-in capital since the Company is currently in an accumulated deficit position.
