Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION The Interim Consolidated Financial Statements present the results of operations, financial position and cash flows of Marriott Vacations Worldwide Corporation (referred to in this report as (i) “we,” “us,” “Marriott Vacations Worldwide,” “MVW” or “the Company,” which includes our consolidated subsidiaries except where the context of the reference is to a single corporate entity, or (ii) “MVWC,” which shall refer only to Marriott Vacations Worldwide Corporation, without its consolidated subsidiaries). In order to make this report easier to read, we refer throughout to (i) our Interim Consolidated Financial Statements as our “Financial Statements,” (ii) our Interim Consolidated Statements of Income as our “Income Statements,” (iii) our Interim Consolidated Balance Sheets as our “Balance Sheets,” and (iv) our Interim Consolidated Statements of Cash Flows as our “Cash Flows.” In addition, references throughout to numbered “Footnotes” refer to the numbered Notes in these Notes to Interim Consolidated Financial Statements, unless otherwise noted. Capitalized terms used and not specifically defined herein have the same meaning given those terms in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 (the “2018 Annual Report”). We use certain other terms that are defined within these Financial Statements. The Financial Statements presented herein and discussed below include 100 percent of the assets, liabilities, revenues, expenses and cash flows of Marriott Vacations Worldwide, all entities in which Marriott Vacations Worldwide has a controlling voting interest (“subsidiaries”), and those variable interest entities for which Marriott Vacations Worldwide is the primary beneficiary in accordance with consolidation accounting guidance. References in these Financial Statements to net income attributable to common shareholders and MVW shareholders’ equity do not include noncontrolling interests, which represent the outside ownership of our consolidated non-wholly owned entities and are reported separately. Intercompany accounts and transactions between consolidated companies have been eliminated in consolidation. These Financial Statements reflect our financial position, results of operations and cash flows as prepared in conformity with United States Generally Accepted Accounting Principles (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Such estimates include, but are not limited to, revenue recognition, allocations of the purchase price paid in business combinations, cost of vacation ownership products, inventory valuation, goodwill and intangibles valuation, property and equipment valuation, accounting for acquired vacation ownership notes receivable, vacation ownership notes receivable reserves, income taxes and loss contingencies. Accordingly, actual amounts may differ from these estimated amounts. In our opinion, our Financial Statements reflect all normal and recurring adjustments necessary to present fairly our financial position, the results of our operations and cash flows for the periods presented. Interim results may not be indicative of fiscal year performance because of, among other reasons, the ILG Acquisition (defined below) and seasonal and short-term variations. These Financial Statements have not been audited. We have condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with GAAP. Although we believe our footnote disclosures are adequate to make the information presented not misleading, the Financial Statements in this report should be read in conjunction with the consolidated financial statements and notes thereto in our 2018 Annual Report. The accompanying Financial Statements also reflect our adoption of new accounting standards. See Footnote 2 “ Significant Accounting Policies and Recent Accounting Standards ” for additional information. Reclassifications We have reclassified the following prior year amounts to conform to the current year presentation: • Reclassified Resort management and other services revenue to Management and exchange revenue; • Reclassified Resort management and other services expense to Management and exchange expense; • Consolidated Consumer financing interest expense into Financing expense; • Reclassified depreciation expense from Marketing and sales expense, Management and exchange expense, Rental expense, and General and administrative expense to Depreciation and amortization expense; • Reclassified $53 million from Accrued liabilities to Accounts payable; • Reclassified $58 million from Accrued liabilities to Advance deposits; • Reclassified $64 million from Accrued liabilities to Deferred revenue; • Reclassified $3 million from Payroll and benefits liability to Accounts payable; • Reclassified $2 million from Payroll and benefits liability to Accrued liabilities; and • Reclassified $20 million of other debt from Debt, net to Securitized debt, net. Acquisition of ILG On September 1, 2018, we completed the acquisition of ILG, LLC, formerly known as ILG, Inc. (“ILG”) through a series of transactions (the “ILG Acquisition”), after which ILG became our indirect wholly-owned subsidiary. We refer to our business associated with brands that existed prior to the ILG Acquisition as “Legacy-MVW” and to ILG’s business and brands that we acquired as “Legacy-ILG.” See Footnote 3 “ Acquisitions and Dispositions ” for more information on the ILG Acquisition.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING STANDARDS New Accounting Standards Accounting Standards Update 2017-12 – “ Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ” (“ASU 2017-12”) In August 2017, the FASB issued ASU 2017-12, which amends and simplifies existing guidance in order to allow companies to better portray the economic effects of risk management activities in the financial statements and enhance the transparency and understandability of the results of hedging activities. ASU 2017-12 eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases certain documentation and assessment requirements. This update was effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The adoption of ASU 2017-12 in the first quarter of 2019 did not have a material impact on our Financial Statements or disclosures. We record derivatives at fair value. The designation of a derivative instrument as a hedge and its ability to meet the hedge accounting criteria determine how we reflect the change in fair value of the derivative instrument in our Financial Statements. A derivative qualifies for hedge accounting if we expect it to be highly effective in offsetting the underlying hedged exposure and we fulfill the hedge documentation requirements. We may designate a hedge as a cash flow hedge, fair value hedge, or a net investment in non-U.S. operations hedge based on the exposure we are hedging. For the effective portion of qualifying hedges, we record changes in fair value in other comprehensive income. We assess the effectiveness of our hedging instruments quarterly, recognize current period hedge ineffectiveness immediately in earnings, and discontinue hedge accounting for any hedge that we no longer consider to be highly effective. We recognize changes in fair value for derivatives not designated as hedges or those not qualifying for hedge accounting in current period earnings. We are exposed to market risk from changes in interest rates, currency exchange rates and debt prices. We manage our exposure to these risks by monitoring available financing alternatives, through pricing policies that may take into account currency exchange rates, and by entering into derivative arrangements. As a matter of policy, we only enter into transactions that we believe will be highly effective at offsetting the underlying risk, and we do not use derivatives for trading or speculative purposes. Accounting Standards Update 2016-02 – “ Leases (Topic 842) ” (“ASU 2016-02”) In February 2016, the FASB issued ASU 2016-02 to increase transparency and comparability of information regarding an entity’s leasing activities by providing additional information to users of financial statements, which as amended, created Accounting Standards Codification 842, Leases (“ASC 842”). ASU 2016-02 requires a lessee to recognize most leases on its balance sheet by recording a liability for its lease obligation and an asset for its right to use the underlying asset as of the lease commencement date and recognizing expenses on the income statement in a similar manner to the superseded guidance in Accounting Standards Codification 840, Leases (“ASC 840”). Lessor accounting remains largely unchanged, other than certain targeted improvements intended to align lessor accounting with the lessee accounting model and with the updated revenue recognition guidance. Upon adoption of ASU 2016-02, as amended, leases will be classified as either finance or operating, with classification affecting the geography of expense recognition in the income statement. Additionally, enhanced quantitative and qualitative disclosures regarding leases are required. ASU 2016-02 was effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. We adopted ASU 2016-02, as amended, during the first quarter of 2019 using the transition method, which allows the application of the standard at the adoption date, January 1, 2019. As permitted by the amended guidance, we elected to retain the original lease classification and historical accounting for existing or expired contracts of lessees and lessors so that we will not be required to reassess whether such contracts contain leases, the lease classification of any such leases or the initial direct costs of any such leases. We continue to report comparative periods presented in the financial statements in the period of adoption under GAAP in effect as of such comparative period, resulting in a balance sheet presentation that is not comparable to the prior period in the first year of adoption. Additionally, with respect to our real estate leases, we elected an accounting policy by class of underlying asset to combine lease and non-lease components. We also elected to apply an exemption for short-term leases whereby leases with an initial term of a year or less are not recorded on the balance sheet. We did not utilize the practical expedient which allows the use of hindsight by lessees and lessors in determining the lease term and in assessing impairment of their right-of-use assets. Upon adoption, we recognized a lease obligation of $165 million and a right-of-use asset of $155 million , as well as, a cumulative-effect adjustment of $8 million to the opening balance of retained earnings for our operating and finance leases, primarily related to leases of real estate and other assets. The adoption of ASU 2016-02 did not have a material effect on our Income Statement or Cash Flows for the nine months ended September 30, 2019 . See Footnote 12 “ Leases ” for further discussion of the adoption and the impact on our Financial Statements. Future Adoption of Accounting Standards Accounting Standards Update 2017-04 – “ Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ” (“ASU 2017-04”) In January 2017, the FASB issued ASU 2017-04, which simplifies the subsequent measurement of goodwill by eliminating the second step from the goodwill impairment test. ASU 2017-04 requires an entity to perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and to recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and is applied on a prospective basis, with early adoption permitted. We will adopt ASU 2017-04 during the fourth quarter of 2019, prior to our annual impairment testing. We do not expect the adoption of ASU 2017-04 to have a material effect on our financial statements or disclosures. Accounting Standards Update 2016-13 – “ Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments ” (“ASU 2016-13”) In June 2016, the FASB issued ASU 2016-13, which replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses. The update is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2018. We expect to adopt ASU 2016-13 commencing in fiscal year 2020 and are continuing to evaluate the impact that adoption of this update will have on our financial statements or disclosures.

Business Combinations [Abstract]
ACQUISITIONS AND DISPOSITIONS	3. ACQUISITIONS AND DISPOSITIONS Acquisitions ILG Acquisition On September 1, 2018 , (the “Acquisition Date”), we completed the ILG Acquisition. ILG is a leading provider of professionally delivered vacation experiences with a portfolio of leisure businesses ranging from vacation exchange and rental services to vacation ownership, and is the exclusive global licensee for the Hyatt, Sheraton and Westin brands in vacation ownership. The combination of our brands created a leading global provider of upper-upscale vacation ownership, exchange networks and management services with access to world-class loyalty programs and an expanded portfolio of highly demanded vacation destinations. Shareholders of ILG received 0.165 shares of our common stock and $14.75 in cash for each share of ILG common stock. The following table presents the fair value of each class of consideration transferred at the Acquisition Date, as finalized at September 30, 2019. (in millions, except per share amounts) Equivalent shares of Marriott Vacations Worldwide common stock issued in exchange for ILG outstanding shares 20.5 Marriott Vacations Worldwide common stock price per share as of Acquisition Date $ 119.00 Fair value of Marriott Vacations Worldwide common stock issued in exchange for ILG outstanding shares 2,441 Cash consideration to ILG shareholders, net of cash acquired of $154 million 1,680 Fair value of ILG equity-based awards attributed to pre-combination service 64 Total consideration transferred, net of cash acquired 4,185 Noncontrolling interests 32 $ 4,217 Fair Values of Assets Acquired and Liabilities Assumed We accounted for the ILG Acquisition as a business combination, which required us to record the assets acquired and liabilities assumed at fair value as of the Acquisition Date. The following table presents the fair values of the assets that we acquired and the liabilities that we assumed on the Acquisition Date in connection with the business combination as previously reported at December 31, 2018 and as finalized at September 30, 2019 . During the first three quarters of 2019, we refined our valuation models related to certain acquired property and equipment, inventory, securitized debt and our assumptions related to certain acquired member relationship intangibles. In addition, we recorded an indemnification asset and corresponding liability for tax matters for which we believe we will be indemnified. See Footnote 5 , “ Income Taxes ” for further information. Further, we recorded a receivable for business interruption proceeds collected and we recorded additional liabilities related to the vacation ownership business and for other tax matters. ($ in millions) September 1, 2018 (as reported at December 31, 2018) Adjustments September 1, 2018 (as adjusted at September 30, 2019) Vacation ownership notes receivable $ 753 $ — $ 753 Inventory 474 10 484 Property and equipment 374 11 385 Intangible assets 1,166 (21 ) 1,145 Other assets 620 84 704 Deferred revenue (217 ) (74 ) (291 ) Deferred taxes (179 ) 41 (138 ) Debt (392 ) — (392 ) Securitized debt from VIEs (702 ) (16 ) (718 ) Other liabilities (511 ) (94 ) (605 ) Net assets acquired 1,386 (59 ) 1,327 Goodwill (1) 2,828 62 2,890 $ 4,214 $ 3 $ 4,217 _________________________ (1) Goodwill is calculated as total consideration transferred, net of cash acquired, less identified net assets acquired and it represents the value that we expect to obtain from synergies and growth opportunities from our combined operations. Vacation Ownership Notes Receivable We acquired vacation ownership notes receivable, which consist of loans to customers who purchased vacation ownership products and chose to finance their purchase. These vacation ownership notes receivable are collateralized by the underlying vacation ownership interests (“VOIs”) and generally have terms ranging from five to 15 years. We valued vacation ownership notes receivable using a discounted cash flow model, which calculated a present value of expected future cash flows over the term of the respective vacation ownership notes receivable (Level 2). See Footnote 6 “ Vacation Ownership Notes Receivable ” for additional information. Inventory We acquired inventory, which consisted of completed unsold VOIs and vacation ownership projects under construction. We valued acquired inventory using an income approach, which is primarily based on significant Level 3 assumptions, such as estimates of future income growth, capitalization rates, discount rates and capital expenditure needs of the relevant properties. Property and Equipment We acquired property and equipment, which included four owned hotels, information technology, ancillary business assets, furniture and equipment and land held for future development. We valued property and equipment using a combination of the income, cost, and market approaches, which are primarily based on significant Level 3 assumptions, such as estimates of future income growth, capitalization rates, discount rates and capital expenditure needs of the hotels. Goodwill We allocated the carrying amount of goodwill to our Vacation Ownership and our Exchange & Third-Party Management reporting units. The following table details the carrying amount of our goodwill at September 30, 2019 and December 31, 2018 , and reflects goodwill attributed to the ILG Acquisition. ($ in millions) Vacation Ownership Segment Exchange & Third-Party Management Segment Total Consolidated Balance at December 31, 2018 $ 2,448 $ 380 $ 2,828 Adjustments (7 ) 69 62 Balance at September 30, 2019 $ 2,441 $ 449 $ 2,890 Intangible Assets The following table presents the fair values of ILG’s identified intangible assets and their related estimated useful lives as of the Acquisition Date. Estimated Fair Value ($ in millions) Estimated Useful Life (in years) Member relationships $ 671 15 to 20 Management contracts 357 15 to 25 Management contracts (1) 35 indefinite Trade names and trademarks 82 indefinite $ 1,145 _________________________ (1) The indefinite-lived management contracts, by their terms, continue for the foreseeable horizon. There are no legal, regulatory, contractual, competitive, economic or other factors which limit the period of time over which these resort management contracts are expected to contribute future cash flows. These management contracts are entirely related to the VRI Europe business, which we disposed of in the fourth quarter of 2018. We valued member relationships and management contracts using the multi-period excess earnings method, which is a variation of the income approach. This method estimates an intangible asset’s value based on the present value of the incremental after-tax cash flows attributable to the intangible asset. We valued trade names and trademarks using the relief-from-royalty method, which applies an estimated royalty rate to forecasted future cash flows, discounted to present value. These valuation approaches utilize Level 3 inputs. Deferred Revenue Deferred revenue primarily relates to membership fees, which are deferred and recognized over the terms of the applicable memberships, ranging from one to five years, on a straight-line basis. Additionally, deferred revenue includes maintenance fees collected from owners, in certain cases, which are earned by the relevant property owners’ association over the applicable period. We valued deferred revenue utilizing Level 3 inputs based on a review of existing deferred revenue balances against legal performance obligations. Deferred Income Taxes Deferred income taxes primarily relate to the fair value of assets and liabilities acquired, including vacation ownership notes receivable, inventory, property and equipment, intangible assets and debt. We estimated deferred income taxes based on statutory rates in the jurisdictions of the legal entities where the acquired assets and liabilities are recorded. Debt We valued the IAC Notes (as defined in Footnote 14 “ Debt ”) using a quoted market price, which is considered a Level 2 input as it is observable in the market; however these notes have only a limited trading volume and as such this fair value estimate is not necessarily indicative of the value at which the IAC Notes could be retired or transferred. The carrying value of the outstanding balance on the revolving credit facility that was acquired (the “ILG Revolving Credit Facility”) approximated fair value, as the contractual interest rate was variable plus an applicable margin based on credit rating (Level 3 input). The ILG Revolving Credit Facility was extinguished and all amounts due were repaid in full upon completion of the ILG Acquisition. Securitized Debt from VIEs We valued securitized debt from VIEs using a discounted cash flow model. The significant assumptions in our analysis include default rates, prepayment rates, bond interest rates and other structural factors (Level 3 inputs). Pro Forma Results of Operations The following unaudited pro forma information presents the combined results of operations of Marriott Vacations Worldwide and ILG as if we had completed the ILG Acquisition on December 30, 2016, the last day of our 2016 fiscal year, but using our fair values of assets and liabilities as of the Acquisition Date. As required by GAAP, these unaudited pro forma results do not reflect any synergies from operating efficiencies. Accordingly, these unaudited pro forma results are presented for informational purposes only and are not necessarily indicative of what the actual results of operations of the combined company would have been if the ILG Acquisition had occurred at the beginning of the period presented, nor are they indicative of future results of operations.

INCOME TAXES

INCOME TAXES	9 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	5. INCOME TAXES Our provision for income taxes is calculated using an estimated annual effective tax rate, based upon expected annual income, less losses in certain jurisdictions, permanent items, statutory rates and planned tax strategies in the various jurisdictions in which we operate. However, discrete items related to prior year tax items are treated separately. Our interim effective tax rate was 404.42 percent and 5.19 percent for the three months ended September 30, 2019 and September 30, 2018 , respectively. The increase in effective tax rate is predominately attributable to a change in our projected mix of earnings in international jurisdictions with differing tax rates and jurisdictions where valuation allowances are recorded, primarily as a result of the ILG Acquisition. Our interim effective tax rate was 43.20 percent and 58.16 percent for the nine months ended September 30, 2019 and September 30, 2018 , respectively. The decrease in the effective tax rate is predominately attributable to the change in the mix of expected annual income, partially offset by unfavorable one-time adjustments primarily as a result of the ILG Acquisition. We file income tax returns with U.S. federal and state and non-U.S. jurisdictions and are subject to audits in these jurisdictions. Certain of our returns are being audited in various jurisdictions for years 2012 through 2018. Our unrecognized tax benefit balance could change significantly during the next fiscal year as a result of audits in various jurisdictions. During the nine months ended September 30, 2019 , our unrecognized tax benefit balance had increases of $57 million and no material decreases, resulting in a total unrecognized tax benefit balance of $59 million at September 30, 2019. Our total unrecognized tax benefit balance that, if recognized, would impact our effective tax rate, was $19 million at September 30, 2019 and $2 million at December 31, 2018 . Other During 2019, we finalized our purchase price allocation for the ILG Acquisition and recorded a $87 million reserve for Legacy-ILG tax matters prior to the ILG Acquisition. We expect that we will be indemnified for liabilities of $54 million in connection with Legacy-ILG tax matters pursuant to a Tax Matters Agreement dated May 11, 2016 by and among Starwood Hotels & Resorts Worldwide, Inc. (“Starwood”), Vistana Signature Experiences, Inc., and Interval Leisure Group, Inc., and consequently have recorded a corresponding indemnification asset.

We reflect interest income associated with vacation ownership notes receivable in our Income Statements in the Financing revenues caption. The following table summarizes interest income associated with vacation ownership notes receivable. Three Months Ended Nine Months Ended ($ in millions) September 30, 2019 September 30, 2018 September 30, 2019 September 30, 2018 Interest income associated with vacation ownership notes receivable — securitized $ 58 $ 42 $ 176 $ 95 Interest income associated with vacation ownership notes receivable — non-securitized 11 3 25 18 Total interest income associated with vacation ownership notes receivable $ 69 $ 45 $ 201 $ 113 Acquired Vacation Ownership Notes Receivable As part of the ILG Acquisition, we acquired existing portfolios of vacation ownership notes receivable. These notes receivable are accounted for using the expected cash flow method of recognizing discount accretion based on the expected cash flows from the acquired vacation ownership notes receivable pursuant to ASC 310-30, “ Loans acquired with deteriorated credit quality ” (“ASC 310-30”). At acquisition, we recorded these vacation ownership notes receivable at fair value, which included a credit discount that is accreted as an adjustment to yield over the estimated life of the vacation ownership notes receivable. The fair value of our acquired vacation ownership notes receivable as of the Acquisition Date was determined using a discounted cash flow method, which calculated a present value of expected future cash flows based on scheduled principal and interest payments over the term of the respective vacation ownership notes receivable, while considering anticipated defaults and early repayments based on historical experience. Consequently, the fair value of the acquired vacation ownership notes receivable recorded on our balance sheet as of the Acquisition Date included an estimate for future uncollectible amounts, which became the historical cost basis for that portfolio going forward. The table below presents a rollforward from December 31, 2018 of the accretable yield (interest income) expected to be earned related to our acquired vacation ownership notes receivable, as well as the amount of non-accretable difference at the end of the period. The non-accretable difference represents estimated contractually required payments in excess of estimated cash flows expected to be collected. The accretable yield represents the excess of estimated cash flows expected to be collected over the carrying amount of the acquired vacation ownership notes receivable. ($ in millions) Nine Months Ended September 30, 2019 Accretable yield balance at December 31, 2018 $ 199 Accretion (61 ) Reclassification from non-accretable difference 43 Accretable yield balance at September 30, 2019 $ 181 Non-accretable difference at September 30, 2019 $ 52 The accretable yield is recognized into interest income over the estimated life of the acquired vacation ownership notes receivable using the level yield method. The accretable yield may change in future periods due to changes in the anticipated remaining life of the acquired vacation ownership notes receivable, which may alter the amount of future interest income expected to be collected, and changes in expected future principal and interest cash collections, which impacts the non-accretable difference. The cash flow from our acquired vacation ownership notes receivable are remeasured at period end based on expected future cash flows, which takes into consideration an estimated measure of anticipated defaults and early repayments. We consider historical Legacy-ILG vacation ownership notes receivable performance and the current economic environment in developing the expected future cash flows used in the re-measurement of our acquired vacation ownership notes receivable. The following table shows future contractual principal payments, as well as interest rates for our non-securitized and securitized acquired vacation ownership notes receivable, at September 30, 2019 .

The following table summarizes the activity related to our originated vacation ownership notes receivable reserve. Originated Vacation Ownership Notes Receivable Reserve ($ in millions) Non-Securitized Securitized Total Balance at December 31, 2018 $ 61 $ 79 $ 140 Increase in vacation ownership notes receivable reserve 62 14 76 Securitizations (47 ) 47 — Clean-up call (1) 19 (19 ) — Write-offs (35 ) — (35 ) Defaulted vacation ownership notes receivable repurchase activity (2) 28 (28 ) — Balance at September 30, 2019 $ 88 $ 93 $ 181 _________________________ (1) Refers to our voluntary repurchase of previously securitized non-defaulted vacation ownership notes receivable to retire outstanding vacation ownership notes receivable from our Warehouse Credit Facility. (2) Decrease in securitized vacation ownership notes receivable reserve and increase in non-securitized vacation ownership notes receivable reserve was attributable to the transfer of the reserve when we voluntarily repurchased defaulted securitized vacation ownership notes receivable. Credit Quality of Vacation Ownership Notes Receivable Legacy-MVW Vacation Ownership Notes Receivable Although we consider loans to owners to be past due if we do not receive payment within 30 days of the due date, we suspend accrual of interest only on those loans that are over 90 days past due. We consider loans over 150 days past due to be in default and fully reserve such amounts. We apply payments we receive for vacation ownership notes receivable on non-accrual status first to interest, then to principal and any remainder to fees. We resume accruing interest when vacation ownership notes receivable are less than 90 days past due. We do not accept payments for vacation ownership notes receivable during the foreclosure process unless the amount is sufficient to pay all past due principal, interest, fees and penalties owed and fully reinstate the note. We write off vacation ownership notes receivable against the reserve once we receive title to the vacation ownership products through the foreclosure or deed-in-lieu process or, in Asia Pacific or Europe, when revocation is complete. For both Legacy-MVW non-securitized and securitized vacation ownership notes receivable, we estimated average remaining default rates of 7.00 percent and 7.01 percent as of September 30, 2019 and December 31, 2018 , respectively. A 0.5 percentage point increase in the estimated default rate would have resulted in an increase in our vacation ownership notes receivable reserve of $7 million as of both September 30, 2019 and December 31, 2018 .

All non-performing vacation ownership notes receivable are placed on non-accrual status when they are over 90 days past due. We resume accruing interest when vacation ownership notes receivable are less than 90 days past due. We apply payments we receive for vacation ownership notes receivable on non-performing status first to interest, then to principal, and any remainder to fees. We consider vacation ownership notes receivable to be in default upon reaching 120 days outstanding. We use the origination of the vacation ownership notes receivable by brand (Hyatt, Sheraton or Westin) and the FICO scores of the customer as the primary credit quality indicators for our Legacy-ILG vacation ownership notes receivable, as historical performance indicates that there is a relationship between the default behavior of borrowers and the brand associated with the vacation ownership property they have acquired, supplemented by the FICO scores of the customers. At September 30, 2019 and December 31, 2018 , the weighted average FICO score within our consolidated Legacy-ILG vacation ownership notes receivable pools was 711 and 710 , respectively, based upon the outstanding vacation ownership notes receivable balance at time of origination. The average estimated rate for all future defaults for our Legacy-ILG consolidated outstanding pool of vacation ownership notes receivable as of September 30, 2019 and December 31, 2018 was 12.47 percent and 12.37 percent , respectively. A 0.5 percentage point increase in the estimated default rate on the Legacy-ILG originated vacation ownership notes receivable would have resulted in an increase in the related vacation ownership notes receivable reserve of $2 million and $1 million as of September 30, 2019 and December 31, 2018 , respectively.

FINANCIAL INSTRUMENTS	7. FINANCIAL INSTRUMENTS The following table shows the carrying values and the estimated fair values of financial assets and liabilities that qualify as financial instruments, determined in accordance with the authoritative guidance for disclosures regarding the fair value of financial instruments. Considerable judgment is required in interpreting market data to develop estimates of fair value. The use of different market assumptions and/or estimation methodologies could have a material effect on the estimated fair value amounts. The table excludes Cash and cash equivalents, Restricted cash, Accounts receivable, Accounts payable, Advance deposits and Accrued liabilities, all of which had fair values approximating their carrying amounts due to the short maturities and liquidity of these instruments. The table also excludes acquired vacation ownership notes receivable which are remeasured at each period end based on expected future cash flows. See Footnote 6 “ Vacation Ownership Notes Receivable ” for additional information on our acquired vacation ownership notes receivable. At September 30, 2019 At December 31, 2018 ($ in millions) Carrying Amount Fair Value Carrying Amount Fair Value Originated vacation ownership notes receivable $ 1,681 $ 1,717 $ 1,388 $ 1,413 Other assets 42 42 66 66 Total financial assets $ 1,723 $ 1,759 $ 1,454 $ 1,479 Securitized debt, net $ (1,686 ) $ (1,717 ) $ (1,714 ) $ (1,718 ) Exchange Notes, net (88 ) (91 ) (88 ) (87 ) Senior Unsecured Notes, net (742 ) (814 ) (741 ) (726 ) IAC Notes (142 ) (144 ) (141 ) (140 ) Term Loan, net (882 ) (899 ) (888 ) (887 ) Revolving Corporate Credit Facility, net (221 ) (221 ) — — Convertible Notes, net (205 ) (231 ) (199 ) (198 ) Non-interest bearing note payable, net — — (30 ) (30 ) Total financial liabilities $ (3,966 ) $ (4,117 ) $ (3,801 ) $ (3,786 ) Originated Vacation Ownership Notes Receivable At September 30, 2019 At December 31, 2018 ($ in millions) Carrying Amount Fair Value Carrying Amount Fair Value Originated vacation ownership notes receivable Securitized $ 1,169 $ 1,199 $ 1,070 $ 1,093 Eligible for securitization 214 220 85 87 Not eligible for securitization 298 298 233 233 Non-securitized 512 518 318 320 $ 1,681 $ 1,717 $ 1,388 $ 1,413 We estimate the fair value of our originated vacation ownership notes receivable that have been securitized using a discounted cash flow model. We believe this is comparable to the model that an independent third party would use in the current market. Our model uses default rates, prepayment rates, coupon rates and loan terms for our securitized vacation ownership notes receivable portfolio as key drivers of risk and relative value to determine the fair value of the underlying vacation ownership notes receivable. We concluded that this fair value measurement should be categorized within Level 3. Due to factors that impact the general marketability of our originated vacation ownership notes receivable that have not been securitized, as well as current market conditions, we bifurcate our non-securitized vacation ownership notes receivable at each balance sheet date into those eligible and not eligible for securitization using criteria applicable to current securitization transactions in the ABS market. Generally, vacation ownership notes receivable are considered not eligible for securitization if any of the following attributes are present: (1) payments are greater than 30 days past due; (2) the first payment has not been received; or (3) the collateral is located in Asia or Europe. In some cases, eligibility may also be determined based on the credit score of the borrower, the remaining term of the loans and other similar factors that may reflect investor demand in a securitization transaction or the cost to effectively securitize the vacation ownership notes receivable. The table above shows the bifurcation of our originated vacation ownership notes receivable that have not been securitized into those eligible and not eligible for securitization based upon the aforementioned eligibility criteria. We estimate the fair value of the portion of our originated vacation ownership notes receivable that have not been securitized that we believe will ultimately be securitized in the same manner as originated vacation ownership notes receivable that have been securitized. We value the remaining originated vacation ownership notes receivable that have not been securitized at their carrying value, rather than using our pricing model. We believe that the carrying value of these particular vacation ownership notes receivable approximates fair value because the stated, or otherwise imputed, interest rates of these loans are consistent with current market rates and the reserve for these vacation ownership notes receivable appropriately accounts for risks in default rates, prepayment rates, discount rates and loan terms. We concluded that this fair value measurement should be categorized within Level 3. Other Assets Other assets include $36 million of company owned insurance policies (the “COLI policies”), acquired on the lives of certain participants in the Marriott Vacations Worldwide Deferred Compensation Plan, that are held in a rabbi trust. The carrying value of the COLI policies is equal to their cash surrender value (Level 2 inputs). In addition, we have investments in marketable securities of $6 million that are marked to market as trading securities using quoted market prices (Level 1 inputs). Securitized Debt We generate cash flow estimates by modeling all bond tranches for our active vacation ownership notes receivable securitization transactions, with consideration for the collateral specific to each tranche. The key drivers in our analysis include default rates, prepayment rates, bond interest rates and other structural factors, which we use to estimate the projected cash flows. In order to estimate market credit spreads by rating, we obtain indicative credit spreads from investment banks that actively issue and facilitate the market for vacation ownership securities and determine an average credit spread by rating level of the different tranches. We then apply those estimated market spreads to swap rates in order to estimate an underlying discount rate for calculating the fair value of the active bonds payable. We concluded that this fair value measurement should be categorized within Level 3. Exchange Notes and IAC Notes We estimate the fair values of our Exchange Notes and our IAC Notes (as defined in Footnote 14 “ Debt ”) using the redemption prices set forth in the redemption notices provided to holders of the Exchange Notes and the IAC Notes during the third quarter of 2019. We concluded that these fair value measurements should be categorized within Level 1. See Footnote 14 “ Debt ” for a discussion of the 2028 Notes (as defined in Footnote 14 “ Debt ”) that were issued subsequent to the third quarter of 2019. Senior Unsecured Notes We estimate the fair value of our Senior Unsecured Notes (as defined in Footnote 14 “ Debt ”) using quoted market prices as of the last trading day for the quarter; however these notes have only a limited trading history and volume and as such this fair value estimate is not necessarily indicative of the value at which the Senior Unsecured Notes could be retired or transferred. We concluded that this fair value measurement should be categorized within Level 2. Term Loan We estimate the fair value of our Term Loan (as defined in Footnote 14 “ Debt ”) using quotes from securities dealers as of the last trading day for the quarter; however these notes have only a limited trading history and volume and as such this fair value estimate is not necessarily indicative of the value at which the Term Loan could be retired or transferred. We concluded that this fair value measurement should be categorized within Level 3. Revolving Corporate Credit Facility We estimate that the fair value of our Revolving Corporate Credit Facility (as defined in Footnote 11 “ Contingencies and Commitments ”) approximates its gross carrying value as the contractual interest rate is variable plus an applicable margin. We concluded that this fair value measurement should be categorized within Level 3. Convertible Notes We estimate the fair value of our Convertible Notes (as defined in Footnote 14 “ Debt ”) using quoted market prices as of the last trading day for the quarter; however these notes have only a limited trading history and volume and as such this fair value estimate is not necessarily indicative of the value at which the Convertible Notes could be retired or transferred. We concluded that this fair value measurement should be categorized within Level 2. The difference between the carrying value and the fair value is primarily attributed to the underlying conversion feature and the spread between the conversion price and the market value of the shares underlying the Convertible Notes.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	8. EARNINGS PER SHARE Basic earnings per common share attributable to common shareholders is calculated by dividing net income or loss attributable to common shareholders by the weighted average number of shares of common stock outstanding during the reporting period. Treasury stock is excluded from the weighted average number of shares of common stock outstanding. Diluted earnings per common share attributable to common shareholders is calculated to give effect to all potentially dilutive common shares that were outstanding during the reporting period, except in periods when there is a loss because the inclusion of the potential common shares would have an anti-dilutive effect. The dilutive effect of outstanding equity-based compensation awards is reflected in diluted earnings per common share applicable to common shareholders by application of the treasury stock method using average market prices during the period. Our calculation of diluted earnings per share attributable to common shareholders reflects our intent to settle conversions of the Convertible Notes through a combination settlement, which contemplates repayment in cash of the principal amount and repayment in shares of our common stock of any excess of the conversion value over the principal amount (the “conversion premium”). Therefore, we include only the shares that may be issued with respect to any conversion premium in total dilutive weighted average shares outstanding, which we calculate using the treasury stock method. As no conversion premium existed as of either September 30, 2019 or September 30, 2018 , there was no dilutive impact from the Convertible Notes for either the third quarter or first three quarters of 2019 or 2018. The shares issuable on exercise of the Warrants (as defined in Footnote 14 “ Debt ”) sold in connection with the issuance of the Convertible Notes will not impact the total dilutive weighted average shares outstanding unless and until the price of our common stock exceeds the strike price, which was subject to adjustment during the third quarter of 2019 to $175.63 , as described in Footnote 14 “ Debt .” If and when the price of our common stock exceeds the strike price of the Warrants, we will include the dilutive effect of the additional shares that may be issued upon exercise of the Warrants in total dilutive weighted average shares outstanding, which we calculate using the treasury stock method. The Convertible Note Hedges (as defined in Footnote 14 “ Debt ”) purchased in connection with the issuance of the Convertible Notes are considered to be anti-dilutive and will not impact our calculation of diluted earnings per share attributable to common shareholders. The table below illustrates the reconciliation of the earnings and number of shares used in our calculation of basic and diluted earnings per share attributable to common shareholders.

In accordance with the applicable accounting guidance for calculating earnings per share, for the first three quarters of 2019 , we excluded from our calculation of diluted earnings per share 249,737 shares underlying stock appreciation rights (“SARs”) that may settle in shares of common stock because the exercise prices of such SARs, which ranged from $97.53 to $143.38 , were greater than the average market price for the applicable period. For the first three quarters of 2018 , we excluded from our calculation of diluted earnings per share 56,649 shares underlying SARs that may settle in shares of common stock because the exercise price of $143.38 of such SARs was greater than the average market price for the applicable period.

A key focus of our comprehensive review was to evaluate opportunities to reduce holdings in markets where we have excess supply so that future inventory spend can be focused on markets that create incremental cost-effective sales locations in areas of high customer demand. We evaluated each asset in the context of its current and anticipated product form, our inventory needs and our operating strategy. During the third quarter of 2019, we completed our evaluation and identified several assets for disposition which we believe will generate cash proceeds equivalent to their estimated fair value of $160 million to $220 million over the next several years. As a result of the change in our development strategy, in the third quarter of 2019, we recorded a non-cash impairment charge of $72 million , of which $61 million related to land and land improvements associated with future phases of three existing resorts, primarily attributable to the fact that the book values of these assets include the historical allocations of common costs incurred when we built the infrastructure of these resorts, $9 million related to a land parcel held for future development and $2 million related to an ancillary business, as the book values of these assets were in excess of the estimated fair values of these assets. We also reviewed the remainder of the assets identified for disposition and determined that no other impairment charges were necessary. We used a combination of the market and income approaches to estimate the fair value of these assets. Under the market approach, a Level 2 input, fair value is measured through an analysis of sales and offerings of comparable property which are adjusted to reflect differences between the asset being valued and the comparable assets, such as location, time and terms of sales, utility and physical characteristics. Under the income approach, a Level 3 input, fair value is measured through a discounted cash flow. Under the income approach, we contemplated alternative uses to comply with the highest and best use provisions of ASC 820. In addition, during the third quarter of 2019, we recorded a non-cash impairment charge of $1 million related to an ancillary asset located at a Vacation Ownership segment property in Europe. During the second quarter of 2019, we entered into a contract to sell land and land improvements associated with a future phase of an existing resort located in Orlando, Florida for $10 million , which was less than the carrying value of the land and land improvements. As a result, we recorded a non-cash impairment of $26 million in the first three quarters of 2019. The impairment is primarily attributable to the fact that the book value of the assets to be sold exceeds the sales price because the book value includes allocations of common costs incurred when we built the infrastructure for the resort, including future phases.

CONTINGENCIES AND COMMITMENTS	11. CONTINGENCIES AND COMMITMENTS Commitments and Letters of Credit As of September 30, 2019 , we had the following commitments outstanding: • We have various contracts for the use of information technology hardware and software that we use in the normal course of business. Our aggregate commitments under these contracts were $67 million , of which we expect $13 million , $26 million , $15 million , $8 million and $5 million will be paid in the remainder of 2019, 2020, 2021, 2022 and 2023, respectively. • We have commitments of $2 million to subsidize operating costs of vacation ownership property owners’ associations, which we expect to pay in the remainder of 2019. • We have a commitment to purchase an operating property located in New York, New York for $182 million , of which $7 million is attributable to a related finance lease arrangement and recorded in Debt. We expect to acquire the units in the property in their current form, over time, and we expect to make payments for these units of $120 million and $62 million in 2020 and 2021, respectively. We currently manage this property, which was rebranded as Marriott Vacation Club Pulse, New York City. See Footnote 17 “ Variable Interest Entities ” for additional information on this transaction and our activities relating to the variable interest entity involved in this transaction. • We have a commitment to purchase 88 vacation ownership units located in Bali, Indonesia for use in our Vacation Ownership segment, contingent upon completion of construction to agreed-upon standards within specified timeframes. We expect to complete the acquisition in 2020 and to make the remaining payments with respect to these units when specific construction milestones are completed, as follows: $3 million in 2019, $23 million in 2020 and $2 million in 2021. • We have a remaining commitment to purchase an operating property located in San Francisco, California for $101 million . We expect to acquire the operating property over time and expect to make payments for the operating property as follows: $55 million in 2020 and $46 million in 2021. We currently manage this property, which was rebranded as Marriott Vacation Club Pulse, San Francisco, during 2019. See Footnote 17 “ Variable Interest Entities ” for additional information on this transaction and our activities relating to the variable interest entity involved in this transaction and Footnote 3 “ Acquisitions and Dispositions ” for information on the purchase that occurred during the third quarter of 2019. Surety bonds issued as of September 30, 2019 totaled $104 million , the majority of which were requested by federal, state or local governments in connection with our operations. As of September 30, 2019 , we had $3 million of letters of credit outstanding under our $600 million revolving credit facility (the “Revolving Corporate Credit Facility”). In addition, as of September 30, 2019 , we had $4 million in letters of credit outstanding related to and in lieu of reserves required for several vacation ownership notes receivable securitization transactions outstanding. These letters of credit are not issued pursuant to, nor do they impact our borrowing capacity under, the Revolving Credit Facility. We estimate the cash outflow associated with completing the phases of our existing portfolio of vacation ownership projects currently under development will be approximately $9 million , of which $4 million is included within liabilities on our Balance Sheet at September 30, 2019 . This estimate is based on our current development plans, which remain subject to change, and we expect the phases currently under development will be completed by the end of 2020. Guarantees Certain of our rental management agreements in our Exchange & Third-Party Management segment provide for owners of properties we manage to receive specified percentages or guaranteed amounts of the rental revenue generated under our management. In these cases, the operating expenses for the rental operations are paid from the revenue generated by the rentals, the owners are then paid their contractual percentages or guaranteed amounts, and our vacation rental business either retains the balance (if any) as its fee or makes up the deficit. At September 30, 2019 , our maximum exposure under these guarantees is $33 million , of which $4 million , $10 million , $9 million , $4 million , $2 million and $4 million relate to the remainder of 2019, 2020, 2021, 2022, 2023 and thereafter. In addition, our maximum exposure under other guarantees is $3 million . Loss Contingencies In March 2017, RCHFU, L.L.C. and other owners at The Ritz-Carlton Club, Aspen Highlands (“RCC Aspen Highlands”) filed a complaint in an action pending in the U.S. District Court for the District of Colorado against us and certain third parties, alleging that their fractional interests were devalued by the affiliation of the RCC Aspen Highlands and other Ritz-Carlton Clubs with our points-based Marriott Vacation Club Destinations (“MVCD”) program. The plaintiffs are seeking compensatory damages, disgorgement, fees and costs. In May 2016, a purported class-action lawsuit was filed in the U.S. District Court for the Middle District of Florida by Anthony and Beth Lennen against us and certain third parties. The complaint challenged the characterization of the beneficial interests in the MVCD trust that are sold to customers as real estate interests under Florida law, the structure of the trust, and associated operational aspects of the trust. The plaintiffs sought declaratory relief, an unwinding of the MVCD product, and punitive damages. In August 2019, the District Court granted our motion for judgment on the pleadings and dismissed the case. The plaintiffs have appealed the ruling. In December 2016, Flora and Bruce Gillespie and other owners and former owners of fractional interests at the Fifth and Fifty-Fifth Residence Club located within The St. Regis, New York (the “St. Regis NY Club”) filed an action in the U.S. District Court for the Southern District of New York against ILG, certain of its subsidiaries, and certain third parties alleging that the sale of less than all interests offered in the fractional offering plan, the amendment of the plan to include additional units, and the rental of unsold fractional interests by the plan’s sponsor breached the relevant agreements and harmed the value of plaintiffs’ fractional interests. The plaintiffs are seeking compensatory damages, rescission, disgorgement, fees and costs. In February 2017, the owners’ association for the St. Regis NY Club filed a separate suit against ILG and certain of its subsidiaries in the U.S. District Court for the Southern District of New York, which was amended to add Marriott International and Starwood as additional defendants in March 2017. The lawsuit was subsequently transferred to the U.S. District Court for the Middle District of Florida. The operative complaint alleges that the sponsor of the St. Regis NY Club (St. Regis Residence Club, New York, Inc.), the St. Regis NY Club manager (St. Regis New York Management, Inc.), and certain affiliated entities, as well as Marriott International and Starwood, breached their fiduciary duties related to sale and rental practices, and further alleges tortious interference with the management agreement, unjust enrichment, and anticompetitive conduct. The amended complaint also alleges anticompetitive conduct in connection with the renewal of the St. Regis NY Club management agreement. The plaintiff is seeking declaratory relief in connection with the Starpoint conversion program and the exchange program at the St. Regis NY Club, unspecified damages, and disgorgement of payments under the management and purchase agreements. In April 2019, a purported class-action lawsuit was filed by Alan and Marjorie Helman and others against us in the Superior Court of the Virgin Islands, Division of St. Thomas alleging that their fractional interests were devalued by the affiliation of The Ritz-Carlton Club, St. Thomas and other Ritz-Carlton Clubs with our MVCD program. The lawsuit was subsequently removed to the U.S. District Court for the District of the Virgin Islands. The plaintiffs are seeking unspecified damages, disgorgement of profits, fees and costs. In May 2019, the G.A. Resort Condominium Association Inc., the owners’ association for the fractional owners at the Hyatt Residence Club Grand Aspen resort (“HRC Grand Aspen”) filed a lawsuit against us in the District Court for the County of Pitkin, Colorado relating to the transfer of ownership of developer-owned fractional interests at HRC Grand Aspen to the HPC Trust Club for sale and use as a part of the Hyatt Residence Club Portfolio Program. The lawsuit was subsequently removed to the U.S. District Court for the District of Colorado. The plaintiff is seeking termination of the management agreement with the owners’ association, the annulment of certain amendments to governing documents at HRC Grand Aspen, the removal of fractional interests at HRC Grand Aspen from the HPC Trust Club, unspecified damages, disgorgement of profits, fees and costs. We believe we have meritorious defenses to the claims in each of the above matters and intend to vigorously defend each matter. In the ordinary course of our business, various claims and lawsuits have been filed or are pending against us. A number of these lawsuits and claims may exist at any given time. We record and accrue for legal contingencies when we determine that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In making such determinations, we evaluate, among other things, the degree of probability of an unfavorable outcome and, when it is probable that a liability has been incurred, our ability to make a reasonable estimate of loss. We review these accruals each reporting period and make revisions based on changes in facts and circumstances. We have not accrued for any of the pending matters described above and we cannot estimate a range of the potential liability associated with these pending matters, if any, at this time. We have accrued for other claims and lawsuits, but the amount accrued is not material in the aggregate. For matters not requiring accrual, we do not believe that the ultimate outcome of such matters, individually and in the aggregate, will materially harm our financial position, cash flows, or overall trends in results of operations based on information currently available. However, legal proceedings are inherently uncertain, and while we believe that our accruals are adequate and/or we have valid defenses to the claims asserted, unfavorable rulings could occur that could, individually or in the aggregate, have a material adverse effect on our business, financial condition, or operating results. Other During June 2018, we identified forged and fraudulently induced electronic payment disbursements we made to third parties in an aggregate amount of $10 million resulting from unauthorized third-party access to our email system. Upon detection, we immediately notified law enforcement authorities and relevant financial institutions and commenced a forensic investigation. During 2018, we recovered $6 million . During the second quarter of 2019, we received $3 million from our insurance company as final settlement of our claim, and the insurance company waived the requirement for us to reimburse the insurance company for any monies subsequently recovered. We recorded a gain of $3 million in the (Losses) gains and other (expense) income, net line of our Income Statement for the first three quarters of 2019. Any additional recoveries will be recorded in our results in the future. We have concluded that this event did not involve access to any of our other systems. No other misappropriation of assets was identified during our investigation. Insurance Recoveries In September 2017, over 20 of our Legacy-MVW properties were impacted by Hurricane Irma and Hurricane Maria and, as a result, as of December 31, 2017, we accrued $1 million for the estimated property damage insurance deductibles and impairment of property and equipment, which was recorded in the Gains and other income, net line on our Income Statement for the year ended December 31, 2017. In 2018, we received $32 million of insurance proceeds related to the settlement of Legacy-MVW business interruption insurance claims arising from Hurricane Irma. These proceeds, and the related deductible of $3 million , were recorded net in the Gains and other income, net line on our Income Statement for the year ended December 31, 2018. During the first quarter of 2019, we recorded an additional $9 million of other income relating to the final settlement of these business interruption insurance claims, which was recorded in the (Losses) gains and other (expense) income, net line on our Income Statement for the nine months ended September 30, 2019 .

Leases [Abstract]
LEASES	12. LEASES We account for leases in accordance with ASC 842, which we adopted using the optional transition method in the period of adoption as of January 1, 2019, without retrospective application to comparative periods. See Footnote 2 “ Significant Accounting Policies and Recent Accounting Standards ” for additional information. Operating leases include lease arrangements for various land, corporate facilities, real estate and equipment. We also have a long-term land lease for land underlying an operating hotel (term of 50 years). Corporate facilities leases are for office space, including our corporate headquarters in Orlando, Florida, and have lease terms that range from nine to 14 years. Other operating leases are primarily for office and retail space, as well as various equipment supporting our operations, with varying terms and renewal option periods. Finance leases (analogous to capital leases under ASC 840) include lease arrangements for ancillary and operations space for which it is reasonably certain we will exercise the option to purchase the underlying assets in connection with the commitment to purchase the associated operating property. See Footnote 11 “ Contingencies and Commitments ” for additional information regarding these transactions. In addition, we also lease various equipment supporting our operations and classify these leases as finance leases in accordance with ASC 842. The depreciable life of these assets is limited to the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Right-of-use assets and lease liabilities are recognized based on the present value of lease payments over the lease term at commencement date. For purposes of calculating lease liabilities, lease terms may be deemed to include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Macro-economic conditions are the primary factor used to estimate whether an option to extend a lease term will be exercised or not. For existing leases that commenced prior to the adoption of ASC 842, we made an accounting policy election to use our incremental borrowing rate, considering the remaining lease term and remaining minimum rental payments during transition, in establishing our lease liabilities. For new leases entered into after the adoption of ASC 842, we will use an incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Certain of our lease agreements include variable rental payments that are based on a percentage of retail sales over contractual levels and others include rental payments adjusted periodically for inflation.

Debt Disclosure [Abstract]
SECURITIZED DEBT	13. SECURITIZED DEBT The following table provides detail on our securitized debt, net of unamortized debt issuance costs. ($ in millions) At September 30, 2019 At December 31, 2018 Vacation ownership notes receivable securitizations, gross (1) $ 1,624 $ 1,590 Unamortized debt discount and issuance costs (14 ) (11 ) 1,610 1,579 Warehouse Credit Facility, gross (2) 56 116 Unamortized debt issuance costs — (1 ) 56 115 Other (3) 20 20 $ 1,686 $ 1,714 _________________________ (1) Interest rates as of September 30, 2019 range from 2.2% to 6.3% , with a weighted average interest rate of 2.9% (2) Effective interest rate as of September 30, 2019 was 3.3% (3) Non-recourse See Footnote 17 “ Variable Interest Entities ” for a discussion of the collateral for the non-recourse debt associated with the securitized vacation ownership notes receivable and our non-recourse warehouse credit facility (the “Warehouse Credit Facility”). The debt associated with our vacation ownership notes receivable securitizations and our Warehouse Credit Facility is non-recourse to us. Vacation Ownership Notes Receivable Securitizations On May 23, 2019, we completed the securitization of a pool of $459 million of vacation ownership notes receivable. In connection with the securitization, investors purchased in a private placement $450 million in vacation ownership loan backed notes from MVW 2019-1 LLC (the “2019-1 LLC”). Three classes of vacation ownership loan backed notes were issued by the 2019-1 LLC: $350 million of Class A Notes, $67 million of Class B Notes and $33 million of Class C Notes. The Class A Notes have an interest rate of 2.89 percent , the Class B Notes have an interest rate of 3.00 percent and the Class C Notes have an interest rate of 3.33 percent , for an overall weighted average interest rate of 2.94 percent . On October 10, 2019, subsequent to the third quarter of 2019, we completed the securitization of a pool of $315 million of vacation ownership notes receivable. Approximately $236 million of the vacation ownership notes receivable were purchased on October 10, 2019 by MVW 2019-2 LLC (the “2019-2 LLC”), and we expect the remaining vacation ownership notes receivable to be purchased by the 2019-2 LLC prior to March 31, 2020. The 2019-2 LLC holds the remaining proceeds, which will be released as the remaining vacation ownership notes receivable are purchased. On November 7, 2019, an additional $44 million of the remaining vacation ownership notes receivable were purchased and $42 million was released from restricted cash. Any funds not used to purchase vacation ownership notes receivable will be returned to the investors. Three classes of vacation ownership loan backed notes were issued by the 2019-2 LLC: $232 million of Class A Notes, $54 million of Class B Notes and $23 million of Class C Notes. The Class A Notes have an interest rate of 2.22 percent , the Class B Notes have an interest rate of 2.44 percent and the Class C Notes have an interest rate of 2.68 percent , for an overall weighted average interest rate of 2.29 percent . Each of the securitized vacation ownership notes receivable transactions contains various triggers relating to the performance of the underlying vacation ownership notes receivable. If a pool of securitized vacation ownership notes receivable fails to perform within the pool’s established parameters (default or delinquency thresholds vary by transaction), transaction provisions effectively redirect the monthly excess spread we would otherwise receive from that pool (attributable to the interests we retained) to accelerate the principal payments to investors (taking into account the subordination of the different tranches to the extent there are multiple tranches) until the performance trigger is cured. During the third quarter of 2019 , and as of September 30, 2019 , no securitized vacation ownership notes receivable pools were out of compliance with their respective established parameters. As of September 30, 2019 , we had 11 securitized vacation ownership notes receivable pools outstanding. As the contractual terms of the underlying securitized vacation ownership notes receivable determine the maturities of the non-recourse debt associated with them, actual maturities may occur earlier than shown below due to prepayments by the vacation ownership notes receivable obligors. The following table shows scheduled future principal payments for our securitized debt as of September 30, 2019 .

During the first quarter of 2019, we securitized vacation ownership notes receivable under our Warehouse Credit Facility. The carrying amount of the vacation ownership notes receivable securitized was $146 million . The advance rate was 85 percent , which resulted in gross proceeds of $124 million . Net proceeds were $123 million due to the funding of reserve accounts of $1 million . During the third quarter of 2019, we securitized vacation ownership notes receivable under our Warehouse Credit Facility. The carrying amount of the vacation ownership notes receivable securitized was $67 million . The advance rate was 85 percent , which resulted in gross proceeds of $57 million . Net proceeds were $57 million due to the funding of reserve accounts of less than $1 million .

On September 17, 2019, we announced the offer and pricing of senior notes, and on October 1, 2019, subsequent to the third quarter of 2019, we issued $350 million aggregate principal amount of 4.750% Senior Notes due 2028 (the “2028 Notes”). We will pay interest on the 2028 Notes on March 15 and September 15 of each year, commencing on March 15, 2020. The net proceeds from the 2028 Notes were used (i) to redeem all of the outstanding IAC Notes, (ii) to redeem all of the outstanding Exchange Notes, (iii) to repay a portion of the outstanding borrowings under our Revolving Corporate Credit Facility, (iv) to pay transaction expenses and fees in connection with each of the foregoing and (v) for general corporate purposes. Corporate Credit Facility Our corporate credit facility (“Corporate Credit Facility”), which provides support for our business, including ongoing liquidity and letters of credit, includes a $900 million term loan facility (the “Term Loan”) which matures on August 31, 2025, and a Revolving Corporate Credit Facility with a borrowing capacity of $600 million that terminates on August 31, 2023. The Term Loan bears interest at LIBOR plus 2.25 percent . Borrowings under the Revolving Corporate Credit Facility generally bear interest at a floating rate plus an applicable margin that varies from 0.50 percent to 2.75 percent depending on the type of loan and our credit rating. In addition, we pay a commitment fee on the unused availability under the Revolving Corporate Credit Facility at a rate that varies from 20 to 40 basis points per annum, also depending on our credit rating. The Revolving Corporate Credit Facility also includes a letter of credit sub-facility of $75 million . As of September 30, 2019 , we were in compliance with the applicable financial and operating covenants under the Corporate Credit Facility. We entered into $250 million of interest rate swaps under which we pay a fixed rate of 2.9625 percent and receive a floating interest rate through September 2023 and $200 million of interest rate swaps under which we pay a fixed rate of 2.2480 percent and receive a floating interest rate through April 2024, in each case to hedge a portion of our interest rate risk on the Term Loan. We also entered into a $100 million interest rate collar with a cap strike rate of 2.5000% and a floor strike rate of 1.8810% through April 2024 to further hedge our interest rate risk on the Term Loan. Both the interest rate swaps and the interest rate collar have been designated and qualify as cash flow hedges of interest rate risk and recorded in Other liabilities on our Balance Sheet as of September 30, 2019 . We characterize payments we make in connection with these derivative instruments as interest expense and a reclassification of accumulated other comprehensive income for presentation purposes.

The conversion rate is subject to adjustment for certain events as described in the indenture governing the notes and was subject to adjustment during the third quarter of 2019 to 6.7887 shares of common stock per $1,000 principal amount of Convertible Notes (equivalent to a conversion price of approximately $147.30 per share of our common stock) when we declared a quarterly dividend of $0.45 per share, which was greater than the quarterly dividend at the time of the issuance of the Convertible Notes. Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. It is our intent to settle conversions of the Convertible Notes through combination settlement, which contemplates repayment in cash of the principal amount and repayment in shares of our common stock of any excess of the conversion value over the principal amount. As of September 30, 2019 , the effective interest rate was 4.7% and the remaining discount amortization period was 3.0 years .

The strike price was subject to adjustment during the third quarter of 2019 to $175.63 per share when we declared a quarterly dividend of $0.45 per share. As of September 30, 2019 , no Convertible Note Hedges or Warrants have been exercised. Finance Leases See Footnote 12 “ Leases ” for information on our finance leases accounted for under ASC 842. Restrictions Amounts borrowed under the Corporate Credit Facility, as well as obligations with respect to letters of credit issued pursuant to that facility, are secured by a perfected first priority security interest in substantially all of the assets of the borrowers under, and guarantors of, that facility (which include MVWC and certain of our direct and indirect, existing and future, domestic subsidiaries, excluding certain bankruptcy remote special purpose subsidiaries), in each case including inventory, subject to certain exceptions. The IAC Notes are guaranteed by MVWC, ILG and certain other subsidiaries whose voting securities are wholly owned directly or indirectly by ILG. The Senior Unsecured Notes are guaranteed by MVWC and certain of its subsidiaries whose voting securities are wholly owned directly or indirectly by MVWC. The Exchange Notes are guaranteed by MVWC and its domestic subsidiaries that guarantee the Corporate Credit Facility. See Footnote 19 “ Supplemental Guarantor Information

Share-based Payment Arrangement [Abstract]
SHARE-BASED COMPENSATION	16. SHARE-BASED COMPENSATION We maintain the Marriott Vacations Worldwide Corporation Stock and Cash Incentive Plan (the “MVW Stock Plan”) for the benefit of our officers, directors and employees. Under the MVW Stock Plan, we are authorized to award: (1) restricted stock units (“RSUs”) of our common stock, (2) SARs relating to our common stock and (3) stock options to purchase our common stock. A total of 6 million shares are authorized for issuance pursuant to grants under the MVW Stock Plan. As of September 30, 2019 , less than 1 million shares were available for grants under the MVW Stock Plan. As part of the ILG Acquisition, we assumed the Interval Leisure Group, Inc. 2013 Stock and Incentive Plan (the “ILG Stock Plan”) and equity based awards outstanding under the ILG Stock Plan. As of September 30, 2019 , 1 million shares were available for grants under the ILG Stock Plan to Legacy-ILG employees. The following table details our share-based compensation expense related to award grants to our officers, directors and employees: Three Months Ended Nine Months Ended ($ in millions) September 30, 2019 September 30, 2018 September 30, 2019 September 30, 2018 Service-based RSUs $ 4 $ 3 $ 13 $ 9 Performance-based RSUs 3 1 6 4 ILG Acquisition Converted RSUs 2 8 8 8 9 12 27 21 SARs — 1 2 2 Stock options — — — — $ 9 $ 13 $ 29 $ 23 The following table details our deferred compensation costs related to unvested awards: ($ in millions) At September 30, 2019 At December 31, 2018 Service-based RSUs $ 21 $ 16 Performance-based RSUs 14 7 ILG Acquisition Converted RSUs 5 15 40 38 SARs 2 1 Stock options — — $ 42 $ 39 Restricted Stock Units We granted 190,403 service-based RSUs, which are subject to time-based vesting conditions, with a weighted average grant-date fair value of $96.30 , to our employees and non-employee directors during the first three quarters of 2019 . During the first three quarters of 2019 , we also granted performance-based RSUs, which are subject to performance-based vesting conditions, to members of management. A maximum of 287,876 RSUs may be earned under the performance-based RSU awards granted during the first three quarters of 2019 . Stock Appreciation Rights We granted 111,111 SARs, with a weighted average grant-date fair value of $28.89 and a weighted average exercise price of $100.52 , to members of management during the first three quarters of 2019 . We use the Black-Scholes model to estimate the fair value of the SARs granted. The expected stock price volatility was calculated based on the average of the historical and implied volatility of our stock price. The average expected life was calculated using the simplified method, as we have insufficient historical information to provide a basis for estimating average expected life. The risk-free interest rate was calculated based on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumed at the date of grant. The dividend yield assumption listed below is based on the expectation of future payouts. The following table outlines the assumptions used to estimate the fair value of grants during the first three quarters of 2019 : Expected volatility 31.10% Dividend yield 1.76% Risk-free rate 2.59% Expected term (in years) 6.25 Legacy-ILG Deferred Compensation Plan Certain deferred share units (“DSUs”) of ILG common stock were outstanding on the Acquisition Date under the Interval Leisure Group, Inc. Deferred Compensation Plan for Non-Employee Directors. On the Acquisition Date, these DSUs were converted to equity-based awards with respect to MVW’s common stock and cash-based awards, resulting in 12,265 DSUs (“ILG DSUs”) and $1 million of cash-based awards. The ILG DSUs had a weighted average fair value of $114.31 on the Acquisition Date. The services associated with the ILG DSUs were completed as of the Acquisition Date, resulting in no deferred compensation costs. The ILG DSUs and related cash-based awards were paid in full during the first quarter of 2019 and there is no remaining obligation as of September 30, 2019 .

VARIABLE INTEREST ENTITIES	17. VARIABLE INTEREST ENTITIES Variable Interest Entities Related to Our Vacation Ownership Notes Receivable Securitizations We periodically securitize, without recourse, through bankruptcy remote special purpose entities, notes receivable originated in connection with the sale of vacation ownership products. These vacation ownership notes receivable securitizations provide funding for us and transfer the economic risks and substantially all the benefits of the consumer loans we originate to third parties. In a vacation ownership notes receivable securitization, various classes of debt securities issued by a special purpose entity are generally collateralized by a single tranche of transferred assets, which consist of vacation ownership notes receivable. With each vacation ownership notes receivable securitization, we may retain a portion of the securities, subordinated tranches, interest-only strips, subordinated interests in accrued interest and fees on the securitized vacation ownership notes receivable or, in some cases, overcollateralization and cash reserve accounts. We created these bankruptcy remote special purpose entities to serve as a mechanism for holding assets and related liabilities, and the entities have no equity investment at risk, making them variable interest entities. We continue to service the vacation ownership notes receivable, transfer all proceeds collected to these special purpose entities, and retain rights to receive benefits that are potentially significant to the entities. Accordingly, we concluded that we are the entities’ primary beneficiary and, therefore, consolidate them. There is no noncontrolling interest balance related to these entities and the creditors of these entities do not have general recourse to us. As part of the ILG Acquisition, we acquired the variable interests in the entities associated with ILG’s outstanding vacation ownership notes receivable securitization transactions. As these vacation ownership notes receivable securitizations are similar in nature to the Legacy-MVW vacation ownership notes receivable securitizations they have been aggregated for disclosure purposes. The following table shows consolidated assets, which are collateral for the obligations of these variable interest entities, and consolidated liabilities included on our Balance Sheet at September 30, 2019 : ($ in millions) Vacation Ownership Notes Receivable Securitizations Warehouse Credit Facility Total Consolidated Assets Vacation ownership notes receivable, net of reserves $ 1,525 $ 61 $ 1,586 Interest receivable 11 1 12 Restricted cash 54 1 55 Total $ 1,590 $ 63 $ 1,653 Consolidated Liabilities Interest payable $ 2 $ — $ 2 Debt 1,624 56 1,680 Total $ 1,626 $ 56 $ 1,682 The following table shows the interest income and expense recognized as a result of our involvement with these variable interest entities during the third quarter of 2019 : ($ in millions) Vacation Ownership Notes Receivable Securitizations Warehouse Credit Facility Total Interest income $ 57 $ 1 $ 58 Interest expense to investors $ 11 $ 1 $ 12 Debt issuance cost amortization $ 2 $ — $ 2 Administrative expenses $ — $ — $ — The following table shows the interest income and expense recognized as a result of our involvement with these variable interest entities during the first three quarters of 2019 : ($ in millions) Vacation Ownership Notes Receivable Securitizations Warehouse Credit Facility Total Interest income $ 164 $ 12 $ 176 Interest expense to investors $ 37 $ 4 $ 41 Debt issuance cost amortization $ 4 $ 1 $ 5 Administrative expenses $ 1 $ — $ 1 The following table shows cash flows between us and the vacation ownership notes receivable securitization variable interest entities: Nine Months Ended ($ in millions) September 30, 2019 September 30, 2018 Cash Inflows Net proceeds from vacation ownership notes receivable securitizations $ 445 $ 419 Principal receipts 355 227 Interest receipts 156 92 Reserve release 107 109 Total 1,063 847 Cash Outflows Principal to investors (379 ) (208 ) Voluntary repurchases of defaulted vacation ownership notes receivable (35 ) (34 ) Voluntary clean-up call (19 ) (22 ) Interest to investors (36 ) (19 ) Funding of restricted cash (93 ) (117 ) Total (562 ) (400 ) Net Cash Flows $ 501 $ 447 Under the terms of our vacation ownership notes receivable securitizations, we have the right to substitute loans for, or repurchase, defaulted loans at our option, subject to certain limitations. Our maximum exposure to loss relating to the special purpose entities that purchase, sell and own these vacation ownership notes receivable is the overcollateralization amount (the difference between the loan collateral balance and the balance on the outstanding vacation ownership notes receivable), plus cash reserves and any residual interest in future cash flows from collateral. The following table shows cash flows between us and the Warehouse Credit Facility variable interest entity: Nine Months Ended ($ in millions) September 30, 2019 September 30, 2018 Cash Inflows Proceeds from vacation ownership notes receivable securitizations $ 181 $ — Principal receipts 14 — Interest receipts 13 — Reserve release 1 — Total 209 — Cash Outflows Principal to investors (12 ) — Repayment of Warehouse Credit Facility (228 ) — Interest to investors (4 ) (1 ) Funding of restricted cash (1 ) — Total (245 ) (1 ) Net Cash Flows $ (36 ) $ (1 ) Other Variable Interest Entities We have a commitment to purchase an operating property located in San Francisco, California, that we currently manage as Marriott Vacation Club Pulse, San Francisco. Refer to Footnote 11 “ Contingencies and Commitments ” for additional information on the commitment. We are required to purchase the operating property from the third party developer unless the developer has sold the property to another party. The operating property is held by a variable interest entity for which we are not the primary beneficiary as we cannot prevent the variable interest entity from selling the operating property at a higher price. Accordingly, we have not consolidated the variable interest entity. As of September 30, 2019 , our Balance Sheet reflected $2 million in Accounts Receivable, including a note receivable of less than $1 million , and $1 million in Accrued liabilities, relating to our involvement with this variable interest entity. We believe that our maximum exposure to loss as a result of our involvement with this variable interest entity is $1 million as of September 30, 2019 . We have a commitment to purchase an operating property located in New York, New York, that we currently manage as Marriott Vacation Club Pulse, New York City. Refer to Footnote 11 “ Contingencies and Commitments ” for additional information on the commitment. We are required to purchase the completed property from the third party developer unless the developer has sold the property to another party. The property is held by a variable interest entity for which we are not the primary beneficiary as we cannot prevent the variable interest entity from selling the property at a higher price. Accordingly, we have not consolidated the variable interest entity. As of September 30, 2019 , our Balance Sheet reflected $8 million in Property and equipment related to a finance lease and leasehold improvements, $1 million in Accrued liabilities and $7 million in Debt related to the finance lease liability for ancillary and operations space we lease from the variable interest entity. In addition, a note receivable of less than $1 million is included in the Accounts receivable line on the Balance Sheet as of September 30, 2019 . We believe that our maximum exposure to loss as a result of our involvement with this variable interest entity is less than $1 million as of September 30, 2019 . Deferred Compensation Plan We consolidate the liabilities of the Marriott Vacations Worldwide Deferred Compensation Plan and the related assets, which consist of the COLI policies held in the rabbi trust. The rabbi trust is considered a variable interest entity. We are considered the primary beneficiary of the rabbi trust because we direct the activities of the trust and are the beneficiary of the trust. At September 30, 2019 , the value of the assets held in the rabbi trust was $36 million , which is included in the Other line within assets on our Balance Sheets.

BUSINESS SEGMENTS

Segment Reporting [Abstract]
BUSINESS SEGMENTS	18. BUSINESS SEGMENTS We define our reportable segments based on the way in which the chief operating decision maker (“CODM”), currently our chief executive officer, manages the operations of the company for purposes of allocating resources and assessing performance. We operate in two operating and reportable business segments: • Vacation Ownership includes a diverse portfolio of resorts that includes seven vacation ownership brands licensed under exclusive, long-term relationships with Marriott International and Hyatt Hotels Corporation. We are the exclusive worldwide developer, marketer, seller and manager of vacation ownership and related products under the Marriott Vacation Club, Grand Residences by Marriott, Sheraton, Westin and Hyatt Residence Club brands, as well as under Marriott Vacation Club Pulse, an extension to the Marriott Vacation Club brand. We are also the exclusive worldwide developer, marketer and seller of vacation ownership and related products under The Ritz-Carlton Destination Club brand, we have the non-exclusive right to develop, market and sell whole ownership residential products under The Ritz-Carlton Residences brand and have a license to use the St. Regis brand for specified fractional ownership resorts. Our Vacation Ownership segment generates most of its revenues from four primary sources: selling vacation ownership products; managing vacation ownership resorts, clubs and owners’ associations; financing consumer purchases of vacation ownership products; and renting vacation ownership inventory. • Exchange & Third-Party Management, includes exchange networks and membership programs, as well as management of resorts and lodging properties. We provide these services through a variety of brands including Interval International, Trading Places International, Vacation Resorts International, Aqua-Aston and Great Destinations. Exchange & Third-Party Management revenue generally is fee-based and derived from membership, exchange and rental transactions, property and association management, and other related products and services. Our CODM evaluates the performance of our segments based primarily on the results of the segment without allocating corporate expenses or income taxes. We do not allocate corporate interest expense or indirect general and administrative expenses to our segments. We include interest income specific to segment activities within the appropriate segment. We allocate depreciation, other gains and losses, equity in earnings or losses from our joint ventures and noncontrolling interest to each of our segments as appropriate. Corporate and other represents that portion of our results that are not allocable to our segments, including those relating to property owners’ associations consolidated under the voting interest model, as our CODM does not use this information to make operating segment resource allocations. Prior year segment information has been reclassified to conform to the current reportable segment presentation. Our CODM uses Adjusted EBITDA to evaluate the profitability of our operating segments, and the components of net income attributable to common shareholders excluded from Adjusted EBITDA are not separately evaluated. Adjusted EBITDA is defined as net income attributable to common shareholders, before interest expense (excluding consumer financing interest expense associated with term loan securitization transactions), income taxes, depreciation and amortization, excluding share-based compensation expense and adjusted for certain items that affect the comparability or our operating performance. Our reconciliation of the aggregate amount of Adjusted EBITDA for our reportable segments to consolidated net income attributable to common shareholders is presented below.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2019
Accounting Policies [Abstract]
Derivative Instruments	We record derivatives at fair value. The designation of a derivative instrument as a hedge and its ability to meet the hedge accounting criteria determine how we reflect the change in fair value of the derivative instrument in our Financial Statements. A derivative qualifies for hedge accounting if we expect it to be highly effective in offsetting the underlying hedged exposure and we fulfill the hedge documentation requirements. We may designate a hedge as a cash flow hedge, fair value hedge, or a net investment in non-U.S. operations hedge based on the exposure we are hedging. For the effective portion of qualifying hedges, we record changes in fair value in other comprehensive income. We assess the effectiveness of our hedging instruments quarterly, recognize current period hedge ineffectiveness immediately in earnings, and discontinue hedge accounting for any hedge that we no longer consider to be highly effective. We recognize changes in fair value for derivatives not designated as hedges or those not qualifying for hedge accounting in current period earnings. We are exposed to market risk from changes in interest rates, currency exchange rates and debt prices. We manage our exposure to these risks by monitoring available financing alternatives, through pricing policies that may take into account currency exchange rates, and by entering into derivative arrangements. As a matter of policy, we only enter into transactions that we believe will be highly effective at offsetting the underlying risk, and we do not use derivatives for trading or speculative purposes.
New Accounting Pronouncements	New Accounting Standards Accounting Standards Update 2017-12 – “ Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ” (“ASU 2017-12”) In August 2017, the FASB issued ASU 2017-12, which amends and simplifies existing guidance in order to allow companies to better portray the economic effects of risk management activities in the financial statements and enhance the transparency and understandability of the results of hedging activities. ASU 2017-12 eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases certain documentation and assessment requirements. This update was effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The adoption of ASU 2017-12 in the first quarter of 2019 did not have a material impact on our Financial Statements or disclosures. We record derivatives at fair value. The designation of a derivative instrument as a hedge and its ability to meet the hedge accounting criteria determine how we reflect the change in fair value of the derivative instrument in our Financial Statements. A derivative qualifies for hedge accounting if we expect it to be highly effective in offsetting the underlying hedged exposure and we fulfill the hedge documentation requirements. We may designate a hedge as a cash flow hedge, fair value hedge, or a net investment in non-U.S. operations hedge based on the exposure we are hedging. For the effective portion of qualifying hedges, we record changes in fair value in other comprehensive income. We assess the effectiveness of our hedging instruments quarterly, recognize current period hedge ineffectiveness immediately in earnings, and discontinue hedge accounting for any hedge that we no longer consider to be highly effective. We recognize changes in fair value for derivatives not designated as hedges or those not qualifying for hedge accounting in current period earnings. We are exposed to market risk from changes in interest rates, currency exchange rates and debt prices. We manage our exposure to these risks by monitoring available financing alternatives, through pricing policies that may take into account currency exchange rates, and by entering into derivative arrangements. As a matter of policy, we only enter into transactions that we believe will be highly effective at offsetting the underlying risk, and we do not use derivatives for trading or speculative purposes. Accounting Standards Update 2016-02 – “ Leases (Topic 842) ” (“ASU 2016-02”) In February 2016, the FASB issued ASU 2016-02 to increase transparency and comparability of information regarding an entity’s leasing activities by providing additional information to users of financial statements, which as amended, created Accounting Standards Codification 842, Leases (“ASC 842”). ASU 2016-02 requires a lessee to recognize most leases on its balance sheet by recording a liability for its lease obligation and an asset for its right to use the underlying asset as of the lease commencement date and recognizing expenses on the income statement in a similar manner to the superseded guidance in Accounting Standards Codification 840, Leases (“ASC 840”). Lessor accounting remains largely unchanged, other than certain targeted improvements intended to align lessor accounting with the lessee accounting model and with the updated revenue recognition guidance. Upon adoption of ASU 2016-02, as amended, leases will be classified as either finance or operating, with classification affecting the geography of expense recognition in the income statement. Additionally, enhanced quantitative and qualitative disclosures regarding leases are required. ASU 2016-02 was effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. We adopted ASU 2016-02, as amended, during the first quarter of 2019 using the transition method, which allows the application of the standard at the adoption date, January 1, 2019. As permitted by the amended guidance, we elected to retain the original lease classification and historical accounting for existing or expired contracts of lessees and lessors so that we will not be required to reassess whether such contracts contain leases, the lease classification of any such leases or the initial direct costs of any such leases. We continue to report comparative periods presented in the financial statements in the period of adoption under GAAP in effect as of such comparative period, resulting in a balance sheet presentation that is not comparable to the prior period in the first year of adoption. Additionally, with respect to our real estate leases, we elected an accounting policy by class of underlying asset to combine lease and non-lease components. We also elected to apply an exemption for short-term leases whereby leases with an initial term of a year or less are not recorded on the balance sheet. We did not utilize the practical expedient which allows the use of hindsight by lessees and lessors in determining the lease term and in assessing impairment of their right-of-use assets. Upon adoption, we recognized a lease obligation of $165 million and a right-of-use asset of $155 million , as well as, a cumulative-effect adjustment of $8 million to the opening balance of retained earnings for our operating and finance leases, primarily related to leases of real estate and other assets. The adoption of ASU 2016-02 did not have a material effect on our Income Statement or Cash Flows for the nine months ended September 30, 2019 . See Footnote 12 “ Leases ” for further discussion of the adoption and the impact on our Financial Statements.
Future Adoption of New Accounting Standards	Future Adoption of Accounting Standards Accounting Standards Update 2017-04 – “ Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ” (“ASU 2017-04”) In January 2017, the FASB issued ASU 2017-04, which simplifies the subsequent measurement of goodwill by eliminating the second step from the goodwill impairment test. ASU 2017-04 requires an entity to perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and to recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and is applied on a prospective basis, with early adoption permitted. We will adopt ASU 2017-04 during the fourth quarter of 2019, prior to our annual impairment testing. We do not expect the adoption of ASU 2017-04 to have a material effect on our financial statements or disclosures. Accounting Standards Update 2016-13 – “ Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments ” (“ASU 2016-13”) In June 2016, the FASB issued ASU 2016-13, which replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses. The update is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2018. We expect to adopt ASU 2016-13 commencing in fiscal year 2020 and are continuing to evaluate the impact that adoption of this update will have on our financial statements or disclosures.
