| Compensation Actually Paid vs. Other Measure [Text Block] | We view consolidated adjusted OFCF as the most important financial measure linking our NEOs’ compensation actually paid to our performance, with performance on that measure accounting for 50%, 50% and 45% of our annual bonus program for 2020, 2021 and 2022, respectively. Accordingly, the graph below reflects general alignment between our consolidated adjusted OFCF and compensation actually paid to Mr. Nair and our other NEOs for 2020 through 2022. | | |
| Measure Name | •Consolidated adjusted OFCF | | |
| Non-GAAP Measure Description [Text Block] | Consolidated adjusted OFCF is OFCF as adjusted each year in accordance with our annual bonus program and for certain other unbudgeted events that the compensation committee, in its discretion and consistent with past practice, determined distorted performance against the financial performance metrics. Historically, OFCF adjustments apply foreign currency exchange rates for the covered year to our OFCF for the immediately preceding year and include the impact of acquisitions, dispositions, volcanic activity, hurricanes and power outages. OFCF is defined as (i) operating income before depreciation and amortization, share-based compensation, provisions and provision releases related to significant litigation and impairment, restructuring and other operating items, less (ii) property and equipment additions. Other operating items include (i) gains and losses on the disposition of long-lived assets, (ii) third-party costs directly associated with successful and unsuccessful acquisitions and dispositions, including legal, advisory and due diligence fees, as applicable, and (iii) other acquisition-related items, such as gains and losses on the settlement of contingent consideration. | | |
