Revenue from Contract with Customer [Abstract]

Revenue

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 revenue is recognized at a point in time rather than over time as the Company completes its performance obligations. Specifically, revenue is recognized when control transfers to the customer, typically 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 16 — Segment Information for further details for revenue by segment and geographic location.

At March 31, 2022, we estimated that $303 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 80% of our unsatisfied (or partially unsatisfied) performance obligations as revenue through 2023, with the remaining balance to be recognized in 2024 and thereafter.

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

The revenue recognized during the three months ended March 31, 2022 and 2021 that was included in contract liabilities at the beginning of the period, inclusive of adjustments, amounted to $104,008 and $104,617, respectively.
