due to an outbreak at one of our refineries, may subject us to fines or penalties assessed by governmental authorities or may result in an environmental or safety incident. We may also be subject to liability as a result of claims by impacted workers.
As of May 1, 2020, after giving effect to this offering, we estimate our liquidity would have been approximately $2,000.0 million based on our estimated $805.0 million of cash and cash equivalents, $151.0 million of additional, available borrowing capacity and no subsequent borrowings under our Revolving Credit Facility. If we continue to experience low crude oil prices and deteriorating market conditions, our borrowing capacity under our Revolving Credit Facility may be reduced. As a result, we may require additional capital, and such additional financing may not be available on favorable terms or at all.
Broad economic factors resulting from the current COVID-19 pandemic, including increasing unemployment rates, substantially reduced travel and reduced business and consumer spending, also affect our business. Business closings and layoffs in the markets we operate may adversely affect demand for our refined products. If general economic conditions continue to deteriorate or remain uncertain for an extended period of time, our liquidity and ability to repay our outstanding debt may be harmed.
In addition, our results and financial condition may be adversely affected by federal or state laws, regulations, orders, or other governmental or regulatory actions addressing the current COVID-19 pandemic or the U.S. refining industry, which, if adopted, could result in direct or indirect restrictions to our business, financial condition, results of operations and cash flow.
Furthermore, the current COVID-19 pandemic has caused disruption in the financial markets and the businesses of financial institutions. These factors have caused a slowdown in the decision-making of these institutions, which may affect the timing on which we may obtain any additional funding. There can be no assurance that we will be able to raise additional funds on terms acceptable to us, if at all.
The foregoing and other continued disruptions to our business as a result of the COVID-19 pandemic could result in a material adverse effect on our business, result of operations, financial condition, cash flows and our ability to service our indebtedness and other obligations.
To the extent the COVID-19 pandemic adversely affects our business, financial condition, results of operations and liquidity, it may also have the effect of heightening many of the other risks described in the “Risk Factors” section included in our 2019 Annual Report and in this offering memorandum, as those risk factors are amended or supplemented by subsequent Quarterly Reports on Form 10-Q and other reports and documents we file with the SEC after the date of this offering memorandum.
Our working capital, cash flows and liquidity can be significantly impacted by volatility in commodity prices and refined product demand.
Payment terms for our crude oil purchases are typically longer than those terms we extend to our customers for sales of refined products. Additionally, reductions in crude oil purchases tend to lag demand decreases for our refined products. As a result of this timing differential, the payables for our crude oil purchases are generally proportionally larger than the receivables for our refined product sales. As we are normally in a net payables position, a decrease in commodity prices generally results in a use of working capital. Given we process a significant volume of crude oil, the impact can materially affect our working capital, cash flows and liquidity.
