The introduction of the COVID-19 vaccine during the first quarter of 2021 and the recent availability of the vaccine to the general population has resulted in the rate of new infections trend downwards. Although the downward trend is encouraging, the effect of the pandemic and the actions and changes in consumer behavior resulting from the pandemic continue to impact our business and have significantly reduced global economic activity and caused global demand for oil and gas to decrease at an unprecedented rate. This demand reduction was further exacerbated by disputes over oil production between the Organization of Petroleum Exporting Countries (OPEC) and non-OPEC nations. We continue to experience demand deterioration in 2021 as the market continues to be volatile and challenging. The extent of the impact of the pandemic, including economic impacts that may persist following the widespread deployment of vaccines, and the decline in oil prices on our operational and financial performance will depend on future developments, which are uncertain and cannot be predicted. An extended period of economic disruption could have a material adverse impact on our business, results of operations, access to sources of liquidity and overall financial condition.
