Subsequent Events [Abstract]
Subsequent event	Note 18 – Subsequent event: Following the spread of the COVID-19 virus beyond China in late January 2020, various national, state and local governments began to implement a number of increasingly restrictive measures to contain the spread of the virus, including travel restrictions, gathering limitations, event cancellations, border closures and stay-at-home orders, resulting in sharp contractions of vast areas of the global economy beginning in March 2020. While measured efforts are underway to resume commercial activities in most global markets, the impacts of COVID-19, including the efforts to mitigate its spread, are expected to continue to challenge workers, businesses and governments for the foreseeable future. Although the COVID-19 pandemic had limited impact on our operations during the first quarter of 2020, we believe U.S. and worldwide gross domestic product will be significantly impacted for an indeterminate period, including the demand for our products and those of our customers. Consequently, we expect to report lower sales and earnings than would otherwise have been expected for the remainder of 2020. The extent of the impact will depend on numerous factors, including future developments, and therefore is uncertain and cannot be predicted.
