Subsequent Events	Subsequent Events COVID-19 and Commodity Prices On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus (“COVID-19”) and the risks to the international community as the virus spreads globally beyond its point of origin. In March 2020, the WHO classified the COVID-19 as a pandemic, based on the rapid increase in exposure globally. In addition, in March 2020, members of OPEC failed to agree on production levels which is expected to cause an increased supply and has led to a substantial decrease in oil prices and an increasingly volatile market. Subsequent to December 31, 2019 the price of both oil and gas has decreased primarily as a result of oil demand concerns due to the economic impacts of the COVID-19 virus and anticipated increases in supply from Russia and OPEC, particularly Saudi Arabia. Declines in oil and natural gas prices affect the Company's liquidity to the extent that the Company's commodity hedges do not protect its cash flows from such price declines. Additionally, if oil or natural gas prices remain depressed or continue to decline the Company may be required to record oil and gas property write-downs. Consumer demand has decreased since the spread of the COVID-19 outbreak and new travel restrictions placed by governments in an effort to curtail the spread of the coronavirus. The full impact of the coronavirus and the decrease in oil prices continue to evolve as of the date of this report.

Management is actively monitoring the global situation and the impact or adverse effect on the Company’s results of future operations, financial position, and liquidity in fiscal year 2020.
