Basis of Presentation [Text Block]	1. Basis of Presentation LyondellBasell Industries N.V., together with its consolidated subsidiaries (collectively “LyondellBasell N.V.”), is a worldwide manufacturer of chemicals and polymers, a refiner of crude oil, a significant producer of gasoline blending components and a developer and licensor of technologies for production of polymers. Unless otherwise indicated, the “Company,” “we,” “us,” “our” or similar words are used to refer to LyondellBasell N.V. The accompanying Consolidated Financial Statements are unaudited and have been prepared from the books and records of LyondellBasell N.V. in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X for interim financial information. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States (“U.S. GAAP”) for complete financial statements. In our opinion, all adjustments, including normal recurring adjustments, considered necessary for a fair statement have been included. The results for interim periods are not necessarily indicative of results for the entire year. These Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 .

Accounting Changes and Error Corrections [Abstract]
Accounting and Reporting Changes [Text Block]	2. Accounting and Reporting Changes Recently Adopted Guidance The following table provides a brief description of recently adopted Accounting Standard Updates ("ASU") issued by the Financial Accounting Standards Board ("FASB"). With the exception of the new lease standard, the adoption of the new standards listed below did not have a material impact on our Consolidated Financial Statements. Standard Description ASU 2016-02, Leases (including subsequent amendments) The new guidance establishes a right-of-use model that requires a lessee to recognize a right-of-use asset and lease liability on the balance sheet for all leases with a term greater than 12 months. Leases are classified as finance or operating, with classification affecting the timing and classification of expense recognition. This guidance also enhances disclosure requirements. This guidance is effective for public entities for annual and interim periods beginning after December 15, 2018. We adopted the new standard in the first quarter of 2019. See Note 8 for the disclosures related to the adoption of this guidance. ASU 2016-13, Measurement of Credit Losses on Financial Instruments (including subsequent amendments) This guidance requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected, resulting in the use of a current expected credit loss (“CECL”) model when measuring an impairment of financial instruments. Credit losses related to available-for-sale securities should be recorded in the consolidated income statement through an allowance for credit losses. Estimated credit losses utilizing the CECL model are based on historical experience, current conditions and forecasts that affect collectability. This ASU also modifies the impairment model for available-for-sale debt securities by eliminating the concept of “other than temporary” as well as providing a simplified accounting model for purchased financial assets with credit deterioration since their origination. Standard Description ASU 2018-09, Codification Improvements This guidance makes minor improvements in various subtopics. Some of the amendments within the ASU do not require transition and are effective upon issuance. However, many of the amendments do have transition guidance with effective dates for annual periods beginning after December 15, 2018 for public entities. Our early adoption of this guidance in the first quarter of 2019 did not have a material impact on our Consolidated Financial Statements. ASU 2019-04, Codification Improvements to Credit Losses on Financial Instruments; Derivatives and Hedging; and Financial Instruments The guidance makes minor clarifications and minor improvements to certain aspects of accounting for credit losses, hedging activities and financial instruments. The guidance is effective for annual and interim periods beginning after December 15, 2019. Early adoption is permitted. Our early adoption of this guidance on a modified-retrospective basis in the second quarter of 2019 did not have a material impact on our Consolidated Financial Statements. Accounting Guidance Issued But Not Adopted as of June 30, 2019 We are currently assessing the impact of the standards listed below on our Consolidated Financial Statements. Standard Description ASU 2018-13, Disclosure Framework - Change to the Disclosure Requirements for Fair Value Measurement This guidance eliminates, adds and modifies certain disclosure requirements for fair value measurements as part of its disclosure framework project. It removes transfer disclosures between Level 1 and Level 2 of the fair value hierarchy, and adds disclosures for the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The guidance will be effective for all entities for annual and interim periods beginning after December 15, 2019. Early adoption is permitted. ASU 2018-14, Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans This guidance changes disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. It eliminates the requirement of certain disclosures that are no longer considered cost beneficial; however, it adds more pertinent disclosures. The guidance will be effective for public entities for annual periods ending after December 15, 2020. Early adoption is permitted. ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract This guidance requires a customer in a hosted, cloud computing arrangement that is a service contract to follow the internal-use software guidance to determine which implementation costs to capitalize as assets or expense as incurred. Capitalized costs are amortized over the term of the hosting arrangement when the recognized asset is ready for its intended use. The guidance will be effective for public entities for annual and interim periods beginning after December 15, 2019. Early adoption is permitted.

Business Combinations [Abstract]
Business Combination [Text Block]	3. Business Combination On August 21, 2018 , we acquired all of the outstanding common stock of A. Schulman Inc. , a Delaware corporation, for an aggregate purchase price of approximately $1,940 million . The purchase price was allocated based on the fair value of the acquired assets and liabilities, redeemable non-controlling interests and non-controlling interests assumed on the acquisition date. The allocation is based on preliminary information and is subject to change as additional information concerning final asset and liability valuations is obtained. The primary areas of the preliminary purchase price allocation that have not been finalized relate to the fair value of property, plant and equipment, intangible assets, contingencies and the related impacts on deferred income taxes and cumulative translation adjustments. During the second quarter of 2019, we made certain measurement period adjustments resulting in a $34 million increase of goodwill. This was primarily due to changes in contingencies and deferred taxes.

Leases [Abstract]
Leases [Text Block]	8 . Leases Adoption of the New Lease Accounting Guidance— On January 1, 2019, we adopted ASC 842, Leases and related amendments using the modified retrospective method. Upon adoption, we recognized Operating lease assets and Operating lease liabilities of $1,533 million and $1,553 million , respectively. We also reduced Accrued liabilities and Other liabilities by $2 million and $18 million , respectively. The adoption of this new guidance did not have a material impact on our Consolidated Statements of Income or Cash Flows. We elected the practical expedients that permit us not to reassess our prior conclusions about lease identification, lease classification, initial direct costs and whether existing land easements that were not previously accounted for as leases under previous accounting standards are, or contain a lease under the new standard. We also elected the practical expedient to account for lease and associated non-lease components as a single lease component asset for all asset classes with the exception of utilities and pipeline assets within major manufacturing equipment, which do not have a material impact on our Consolidated Financial Statements. Comparative financial information has not been restated and continues to be reported under the accounting standards in effect for those periods. At inception of a contract, we determine if the contract contains a lease. When a lease is identified, we recognize a right-of-use asset and a corresponding lease liability based on the present value of the lease payments over the lease term discounted using our incremental borrowing rate, unless an implicit rate is readily determinable. Lease payments include fixed and variable lease components. Variable components are derived from usage or market-based indices, such as the consumer price index. Options to extend or terminate the lease are reflected in the lease payments and lease term when it is reasonably certain that we will exercise those options. Leases with an initial term of 12 months or less are not recorded on the balance sheet. We recognize lease expense on a straight-line basis over the lease term. Operating Leases— The majority of our leases are operating leases. We lease storage tanks, terminal facilities, land, office facilities, railcars, pipelines, barges, plant equipment and other equipment. As of June 30, 2019 , our Operating lease assets were $1,560 million . Operating lease liabilities totaled $1,582 million of which $278 million are current and recorded in Accrued liabilities. These values were derived using a weighted average discount rate of 4.2% . Our operating leases have remaining lease terms ranging from less than 1 year to 30 years and have a weighted-average remaining lease term of 7 years . While extension clauses included in our leases do not materially impact our Operating lease assets or Operating lease liabilities, certain leases include options to extend the lease for up to 20 years . Maturities of operating lease liabilities as of June 30, 2019 are as follows: Millions of dollars Last six months of 2019 $ 176 2020 311 2021 262 2022 223 2023 194 Thereafter 704 Total lease payments 1,870 Less: Imputed interest (288 ) Present value of lease liabilities $ 1,582 The following table presents the components of operating lease cost for the three and six months ended June 30, 2019 : Three Months Ended Six Months Ended Millions of dollars Operating lease cost $ 90 $ 180 Short-term lease cost 33 73 Variable lease cost 19 36 Net operating lease cost $ 142 $ 289 Cash paid for operating lease liabilities totaled $183 million for the six months ended June 30, 2019 . Leased assets obtained in exchange for new operating lease liabilities, including all leases recognized upon adoption of the new lease accounting standard, totaled $1,790 million for the six months ended June 30, 2019 . As of June 30, 2019 , we have entered into additional operating leases, with an undiscounted value of $558 million , primarily for storage tanks related to our new PO/TBA plant at our Channelview, Texas facility. These leases, which will commence between the second half of 2019 and 2022 , have lease terms ranging from 2 to 20 years . Lease Commitments— As of December 31, 2018, the undiscounted aggregate future estimated payments for our operating lease commitments, including those which have not commenced, and those with an initial term of 12 months of less, were as follows: Millions of dollars 2019 $ 365 2020 288 2021 256 2022 236 2023 204 Thereafter 1,126 Total minimum lease payments $ 2,475

Financial Instruments and Fair Value [Abstract]
Financial Instruments and Fair Value Measurements [Text Block]	9 . Financial Instruments and Fair Value Measurements We are exposed to market risks, such as changes in commodity pricing, currency exchange rates and interest rates.

Our investments in equity securities discussed below are measured at fair value using the net asset value per share, or its equivalent, practical expedient and have not been classified in the fair value hierarchy. All other derivatives and available-for-sale debt securities in the tables above are classified as Level 2. At June 30, 2019 , our outstanding foreign currency and commodity contracts, not designated as hedges, mature from July 2019 to August 2019 , and July 2019 , respectively. Financial Instruments Not Measured at Fair Value on a Recurring Basis —Due to the short maturity, the fair value of all non-derivative financial instruments included in Current assets and Current liabilities approximates the applicable carrying value. Current assets include Cash and cash equivalents, Restricted cash, held-to-maturity time deposits and Accounts receivable. Current liabilities include Accounts payable and commercial paper. The following table presents the carrying value and estimated fair value of our financial instruments that are not measured at fair value on a recurring basis as of June 30, 2019 and December 31, 2018 . Short-term loans receivable, which represent our repurchase agreements, and short-term and long-term debt are recorded at amortized cost in the Consolidated Balance Sheets. The carrying and fair values of short-term and of long-term debt exclude finance leases and commercial paper.

These swaps were designated as cash flow hedges and will be terminated upon debt issuance. Additionally, concurrent with the redemption of $1,000 million of our then outstanding 5% senior notes due 2019 , we received $4 million in settlement of $1,000 million of forward-starting interest rate swaps designated as cash flow hedges of forecasted interest payments to begin on or before April 15, 2019. In January and February of 2019, we entered into commodity futures contracts with total notional amounts of $78 million and $97 million , respectively, to mitigate the risk of variability in feedstock prices and product sales prices for 2019. In 2019, we paid $5 million in settlement of commodity futures contracts hedging the risk of variability in feedstock prices with a total notional amount of $137 million . Additionally, we received $8 million in settlement of commodity futures contracts hedging the risk of variability in product sales prices with a total notional amount of $127 million . As of June 30, 2019 , on a pre-tax basis, $1 million , $11 million , and $5 million are scheduled to be reclassified from Accumulated other comprehensive loss as increases to interest expense, revenues and cost of sales, respectively, over the next twelve months.

Income Tax Disclosure [Abstract]
Income Taxes [Text Block]	10 . Income Taxes Our effective income tax rate for the three months ended June 30, 2019 was 14.4% compared with - 1.3% for the three months ended June 30, 2018 . For the six months ended June 30, 2019 , the effective income tax rate was 16.9% compared with 8.9% for the first six months ended June 30, 2018. Our effective income tax rate fluctuates based on, among other factors, changes in statutory tax rates, changes in pretax income in countries with varying statutory tax rates, changes in valuation allowances, changes in foreign exchange gains/losses, changes in the amount of exempt income and changes in unrecognized tax benefits associated with uncertain tax positions. Compared with the three and six months ended June 30, 2018 , the higher effective tax rate for the three and six months ended June 30, 2019 was primarily attributable to changes in unrecognized tax benefits associated with uncertain tax positions, partially offset by a tax benefit related to research and development activities. We operate in multiple jurisdictions throughout the world, and our tax returns are periodically audited or subjected to review by tax authorities. We are currently under examination in a number of tax jurisdictions. As a result, there is an uncertainty in income taxes recognized in our financial statements. Positions challenged by the tax authorities may be settled or appealed by us. During the three months ended June 30, 2018 , we entered into an audit settlement impacting specific uncertain tax positions. This audit settlement resulted in a $346 million non-cash benefit to our effective tax rate consisting of the recognition of $288 million of previously unrecognized tax benefits as a reduction for tax positions of prior years and the release of $58 million of previously accrued interest. This non-cash reduction in unrecognized tax benefits is reflected on our Consolidated Statements of Cash Flows in Other operating activities. Tax benefits totaling $275 million and $269 million were unrecognized as of June 30, 2019 and December 31, 2018 , respectively. It is reasonably possible that, within the next twelve months, due to the settlement of uncertain tax positions with various tax authorities and the expiration of statutes of limitations, unrecognized tax benefits could decrease by up to approximately $105 million . We monitor income tax developments in countries where we conduct business. In 2017 , the U.S. enacted “H.R.1,” also known as the “Tax Cuts and Jobs Act” (the “Tax Act”) materially impacting our Consolidated Financial Statements by, among other things, decreasing the tax rate, and significantly affecting future periods. To determine the full effects of the tax law, we are awaiting the finalization of several proposed U.S. Treasury regulations under the Tax Act that were issued during 2018 and 2019. In prior years, the Company did not assert permanent reinvestment of our foreign earnings. However, as a result of the U.S. Section 245A temporary regulations, the Company does intend to permanently reinvest approximately $565 million of our non-U.S. earnings. Repatriation of these earnings to the U.S. in the future could result in a $60 million tax impact. Prior to the issuance of the retroactive temporary regulations, the non-U.S. earnings on the permanent reinvestment could have been distributed tax free.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies [Text Block]	11 . Commitments and Contingencies Commitments —We have various purchase commitments for materials, supplies and services incidental to the ordinary conduct of business, generally for quantities required for our businesses and at prevailing market prices. These commitments are designed to assure sources of supply and are not expected to be in excess of normal requirements. At June 30, 2019 , capital expenditure commitments were incurred in our normal course of business, including commitments of approximately $484 million primarily related to building our new PO/TBA plant on the Texas Gulf Coast. Financial Assurance Instruments —We have obtained letters of credit, performance and surety bonds and have issued financial and performance guarantees to support trade payables, potential liabilities and other obligations. Considering the frequency of claims made against the financial instruments we use to support our obligations, and the magnitude of those financial instruments in light of our current financial position, management does not expect that any claims against or draws on these instruments would have a material adverse effect on our Consolidated Financial Statements. We have not experienced any unmanageable difficulty in obtaining the required financial assurance instruments for our current operations. Environmental Remediation —Our accrued liability for future environmental remediation costs at current and former plant sites and other remediation sites totaled $127 million and $90 million as of June 30, 2019 and December 31, 2018 , respectively. At June 30, 2019 , the accrued liabilities for individual sites range from less than $1 million to $16 million . The remediation expenditures are expected to occur over a number of years, and not to be concentrated in any single year. In our opinion, it is reasonably possible that losses in excess of the liabilities recorded may have been incurred. However, we cannot estimate any amount or range of such possible additional losses. New information about sites, new technology or future developments such as involvement in investigations by regulatory agencies, could require us to reassess our potential exposure related to environmental matters. Indemnification —We are parties to various indemnification arrangements, including arrangements entered into in connection with acquisitions, divestitures and the formation and dissolution of joint ventures. Pursuant to these arrangements, we provide indemnification to and/or receive indemnification from other parties in connection with liabilities that may arise in connection with the transactions and in connection with activities prior to completion of the transactions. These indemnification arrangements typically include provisions pertaining to third party claims relating to environmental and tax matters and various types of litigation. As of June 30, 2019 , we had not accrued any significant amounts for our indemnification obligations, and we are not aware of other circumstances that would likely lead to significant future indemnification obligations. We cannot determine with certainty the potential amount of future payments under the indemnification arrangements until events arise that would trigger a liability under the arrangements. As part of our technology licensing contracts, we give indemnifications to our licensees for liabilities arising from possible patent infringement claims with respect to certain proprietary licensed technologies. Such indemnifications have a stated maximum amount and generally cover a period of 5 to 10 years .

Share Repurchase Programs —In May 2019 , our shareholders approved a proposal to authorize us to repurchase up to 37.0 million of our ordinary shares through November 30, 2020 (“ May 2019 Share Repurchase Program ”), which superseded the remaining authorization under our June 2018 Share Repurchase Program. The timing and amount of these repurchases, which are determined based on our evaluation of market conditions and other factors, may be executed from time to time through open market or privately negotiated transactions. The repurchased shares, which are recorded at cost, are classified as Treasury stock and may be retired or used for general corporate purposes, including for various employee benefit and compensation plans. In June 2019, we commenced a tender offer to purchase up to 37.0 million of our issued and outstanding ordinary shares. In July 2019, upon the expiration of the tender offer, we repurchased 35.1 million ordinary shares at a tender offer price of $88.00 per share for a total of $3,093 million , excluding fees and expenses related to the tender offer.

Segment Reporting [Abstract]
Segment and Related Information [Text Block]	14 . Segment and Related Information In conjunction with our acquisition of A. Schulman in August 2018, polypropylene compounding, Catalloy and polybutene-1, which were previously reflected in our O&P–EAI and O&P–Americas segments, were moved to our Advanced Polymer Solutions segment. All comparable periods presented have been revised to reflect this change. We disclose the results of each of our operating segments in accordance with ASC 280, Segment Reporting . Our operating segments are managed by senior executives who report to our Chief Executive Officer, the chief operating decision maker. Discrete financial information is available for each of the segments, and our Chief Executive Officer uses the operating results of each of the operating segments for performance evaluation and resource allocation. The activities of each of our segments from which they earn revenues and incur expenses are described below: • Olefins and Polyolefins–Americas (“O&P–Americas”). Our O&P–Americas segment produces and markets olefins and co-products, polyethylene and polypropylene. • Olefins and Polyolefins–Europe, Asia, International (“O&P–EAI”). Our O&P–EAI segment produces and markets olefins and co-products, polyethylene, and polypropylene. • Intermediates and Derivatives (“I&D”). Our I&D segment produces and markets propylene oxide and its derivatives; oxyfuels and related products; and intermediate chemicals such as styrene monomer, acetyls, ethylene oxide and ethylene glycol. • Advanced Polymer Solutions (“APS”) . Our APS segment produces and markets compounding and solutions, such as polypropylene compounds, engineered plastics, masterbatches, engineered composites, colors and powders, and advanced polymers, which includes Catalloy and polybutene-1. • Refining . Our Refining segment refines heavy, high-sulfur crude oils and other crude oils of varied types and sources available on the U.S. Gulf Coast into refined products, including gasoline and distillates. • Technology . Our Technology segment develops and licenses chemical and polyolefin process technologies and manufactures and sells polyolefin catalysts. Our chief operating decision maker uses EBITDA as the primary measure for reviewing our segments’ profitability and therefore, in accordance with ASC 280, Segment Reporting , we have presented EBITDA for all segments. We define EBITDA as earnings before interest, taxes and depreciation and amortization. “Other” includes intersegment eliminations and items that are not directly related or allocated to business operations, such as foreign exchange gains or losses and components of pension and other postretirement benefit costs other than service cost. Sales between segments are made primarily at prices approximating prevailing market prices.

Leases (Policies)

Leases (Policies)	6 Months Ended

Leases [Abstract]
Leases [Policy Text Block]	We elected the practical expedients that permit us not to reassess our prior conclusions about lease identification, lease classification, initial direct costs and whether existing land easements that were not previously accounted for as leases under previous accounting standards are, or contain a lease under the new standard. We also elected the practical expedient to account for lease and associated non-lease components as a single lease component asset for all asset classes with the exception of utilities and pipeline assets within major manufacturing equipment, which do not have a material impact on our Consolidated Financial Statements. Comparative financial information has not been restated and continues to be reported under the accounting standards in effect for those periods. At inception of a contract, we determine if the contract contains a lease. When a lease is identified, we recognize a right-of-use asset and a corresponding lease liability based on the present value of the lease payments over the lease term discounted using our incremental borrowing rate, unless an implicit rate is readily determinable. Lease payments include fixed and variable lease components. Variable components are derived from usage or market-based indices, such as the consumer price index. Options to extend or terminate the lease are reflected in the lease payments and lease term when it is reasonably certain that we will exercise those options. Leases with an initial term of 12 months or less are not recorded on the balance sheet. We recognize lease expense on a straight-line basis over the lease term.

Accounting Changes and Error Corrections [Abstract]
Schedule of accounting and reporting changes [Table Text Block]	The following table provides a brief description of recently adopted Accounting Standard Updates ("ASU") issued by the Financial Accounting Standards Board ("FASB"). With the exception of the new lease standard, the adoption of the new standards listed below did not have a material impact on our Consolidated Financial Statements. Standard Description ASU 2016-02, Leases (including subsequent amendments) The new guidance establishes a right-of-use model that requires a lessee to recognize a right-of-use asset and lease liability on the balance sheet for all leases with a term greater than 12 months. Leases are classified as finance or operating, with classification affecting the timing and classification of expense recognition. This guidance also enhances disclosure requirements. This guidance is effective for public entities for annual and interim periods beginning after December 15, 2018. We adopted the new standard in the first quarter of 2019. See Note 8 for the disclosures related to the adoption of this guidance. ASU 2016-13, Measurement of Credit Losses on Financial Instruments (including subsequent amendments) This guidance requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected, resulting in the use of a current expected credit loss (“CECL”) model when measuring an impairment of financial instruments. Credit losses related to available-for-sale securities should be recorded in the consolidated income statement through an allowance for credit losses. Estimated credit losses utilizing the CECL model are based on historical experience, current conditions and forecasts that affect collectability. This ASU also modifies the impairment model for available-for-sale debt securities by eliminating the concept of “other than temporary” as well as providing a simplified accounting model for purchased financial assets with credit deterioration since their origination. Standard Description ASU 2018-09, Codification Improvements This guidance makes minor improvements in various subtopics. Some of the amendments within the ASU do not require transition and are effective upon issuance. However, many of the amendments do have transition guidance with effective dates for annual periods beginning after December 15, 2018 for public entities. Our early adoption of this guidance in the first quarter of 2019 did not have a material impact on our Consolidated Financial Statements. ASU 2019-04, Codification Improvements to Credit Losses on Financial Instruments; Derivatives and Hedging; and Financial Instruments The guidance makes minor clarifications and minor improvements to certain aspects of accounting for credit losses, hedging activities and financial instruments. The guidance is effective for annual and interim periods beginning after December 15, 2019. Early adoption is permitted. Our early adoption of this guidance on a modified-retrospective basis in the second quarter of 2019 did not have a material impact on our Consolidated Financial Statements. Accounting Guidance Issued But Not Adopted as of June 30, 2019 We are currently assessing the impact of the standards listed below on our Consolidated Financial Statements. Standard Description ASU 2018-13, Disclosure Framework - Change to the Disclosure Requirements for Fair Value Measurement This guidance eliminates, adds and modifies certain disclosure requirements for fair value measurements as part of its disclosure framework project. It removes transfer disclosures between Level 1 and Level 2 of the fair value hierarchy, and adds disclosures for the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The guidance will be effective for all entities for annual and interim periods beginning after December 15, 2019. Early adoption is permitted. ASU 2018-14, Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans This guidance changes disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. It eliminates the requirement of certain disclosures that are no longer considered cost beneficial; however, it adds more pertinent disclosures. The guidance will be effective for public entities for annual periods ending after December 15, 2020. Early adoption is permitted. ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract This guidance requires a customer in a hosted, cloud computing arrangement that is a service contract to follow the internal-use software guidance to determine which implementation costs to capitalize as assets or expense as incurred. Capitalized costs are amortized over the term of the hosting arrangement when the recognized asset is ready for its intended use. The guidance will be effective for public entities for annual and interim periods beginning after December 15, 2019. Early adoption is permitted.
