Accounting Policies [Abstract] |
Risks and uncertainties in entity's business | Risks and UncertaintiesThe COVID-19 pandemic has had global economic impacts including disrupting customer demand and global supply chains, resulting in market volatility. The extent of the recent pandemic and its ongoing impact on our operations is volatile, but is being monitored closely by our management. During portions of the first half of 2020 certain of our European factories were closed due to government actions and local conditions, and any further closures that may be imposed on us could impact our results for 2021. New variants of the virus may cause previously lifted restrictions to be reinstated, which could result in more disruptions. Incremental costs we have incurred related to COVID-19, such as personal protective equipment, increased cleaning and sanitizing of our facilities, and other such items, have not been material to date. As economies have reopened, global supply chains have struggled to keep pace with rapidly changing demand. The resulting supply constraints have manifested across a variety of areas including mechanical, electrical and logistics portions of the supply chain, which has impacted our ability to ship products in a timely manner. In particular, our ability to obtain adequate supply of semiconductor components has impacted our ability to service recovering customer demand. While the current imbalance in supply and demand is temporal, the timeline to recovery is uncertain. Efforts are ongoing with suppliers to increase supply, including the approval of alternate sources. At this time, we have not identified any significant decrease in long-term customer demand for our products and services. However, certain of our customer projects have experienced delay in deliveries, with originally forecasted 2021 revenue pushed to future periods.
