Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

2. Revenue

A majority of the Company’s revenue is short cycle in nature with shipments within one year from order. A small portion of the Company’s revenue derives from contracts extending over one year. The Company's payment terms generally range between 30 to 90 days and vary by the location of businesses, the type of products manufactured to be sold and the volume of products sold, among other factors.

Over 95% of the Company’s performance obligations are recognized at a point in time that relate to the manufacture and sale of a broad range of products and components. Revenue is recognized when control transfers to the customer upon shipment or completion of installation, testing, certification, or other substantive acceptance provisions required under the contract. Less than 5% of the Company’s revenue is recognized over time and relates to the sale of equipment or services in which the Company transfers control of a good or service over time and the customer simultaneously receives and consumes the benefits provided by the Company's performance as the Company performs, or our performance creates or enhances an asset the customer controls as the asset is created or enhanced, or our performance does not create an asset with an alternative use to the Company and the Company has an enforceable right to payment for its performance to date plus a reasonable margin.

Revenue from contracts with customers is disaggregated by segment and geographic location, as they best depict the nature and amount of the Company’s revenue. See Note 17 — Segment Information for revenue by segment and geographic location.

At June 30, 2021, we estimated that $272 million in revenue is expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period. We expect to recognize approximately 58% of our unsatisfied (or partially unsatisfied) performance obligations as revenue through 2022, with the remaining balance to be recognized in 2023 and thereafter.

The following table provides information about contract assets and contract liabilities from contracts with customers:

	June 30, 2021		December 31, 2020		December 31, 2019
Contract assets	$	15,079	$	15,020	$	14,894
Contract liabilities - current	189,317		184,845		104,901
Contract liabilities - non-current	22,534		13,921		10,921

In the fourth quarter of 2020, the Company adjusted its prior year balance sheet classification and footnote disclosure related to certain upfront cash consideration received from customers that should have been classified as contract liabilities (included in deferred revenue or other liabilities) rather than customer deposits (included in accounts payable).

The revenue recognized during the six months ended June 30, 2021 and 2020 that was included in contract liabilities at the beginning of the period, inclusive of adjustments, amounted to $139,891 and $63,778, respectively.
