Effect of Covid-19 Pandemic [Text Block]	Note 12 – Impact of COVID-19 The COVID-19 pandemic has created significant economic disruption and uncertainty around the world. The Company continues to closely monitor the developments surrounding COVID-19 and take actions to mitigate the business risks involved. During this challenging time, we remain focused on ensuring the health and safety of our employees by implementing the protocols established by public health officials in addition to meeting the demand of our customers. As an essential supplier currently exempt from government-mandated shutdown directives, we are striving to ensure an uninterrupted flow of our mission critical products serving medical device, first responder, public safety, energy and national security customers. For 2020, we have maintained normal operations at all our facilities with the exception of an approximately one-month closure of our China facility as was mandated by the Chinese government through early March 2020. COVID-19 adversely impacted our operating results during 2020 primarily as a result of overall disruptions in supply chains impacting both commercial and government/defense markets, revenue declines in oil and gas and international industrial markets, and the approximately one-month closure of our China facility. This negative impact was partially offset by increased demand for our medical batteries, especially those used in ventilators, respirators and infusion pumps. The extent to which COVID-19 may further impact our business is uncertain and will depend on many evolving factors which we continue to monitor but cannot predict, including the duration and scope of the pandemic and actions taken by governments, businesses and individuals in response to the pandemic. Potential effects of COVID-19 that may adversely impact our future business include limited availability and/or increased cost of raw materials and components used in our products, reduced demand and/or pricing for our products, inability of our customers to pay for our products or remain solvent, and reduced availability of our workforce. Prolonged adverse effects of COVID-19 on our business could result in the impairment of long-lived assets including goodwill and other intangible assets. Further, we cannot predict all possible adverse effects the COVID-19 pandemic. While we continue to closely monitor the developments surrounding COVID-19 and take actions when possible to mitigate the business risks involved, the potential effects of COVID-19 on our business, alone or taken together, may pose a material risk to our future operating results and financial condition.
