Subsequent Events [Abstract] |
Subsequent Event | Subsequent EventIn March 2020, the World Health Organization characterized the coronavirus ("COVID-19") a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The rapid spread of the pandemic and the continuously evolving responses to combat it have had an increasingly negative impact on the global economy. In view of the rapidly changing business environment, unprecedented market volatility and heightened degree of uncertainty resulting from COVID-19, we are currently unable to fully determine its future impact on our business. However, we are monitoring the progression of the pandemic and its potential effect on our financial position, results of operations and cash flows.On April 22, 2020, our plant and office facilities in Tulsa, Oklahoma experienced hail related weather damage and we have filed a property insurance claim which carries a $500,000 deductible. We did not experience any operational interruption as a result of this weather event.In May 2020, we entered into three material purchase agreements that total approximately $5.1 million. The purchase agreement periods are from September 2020 to January 2021.
