The dollar per bbl commodity price difference between crude oil and condensate (input) and refined products (output) is the most significant driver of refining margins, and they have historically been subject to wide fluctuations. The general outlook for the oil and natural gas industry for 2024 19. Net income for the twelve December 31, 2023 per share per share twelve December 31, 2022 per share Working Capital Improvements We continue to actively explore additional funding to refinance and restructure debt and further improve working capital. During 2023, 2022, million and million in working capital deficits at December 31, 2023 2022 , respectively, representing a million improvement . Excluding the current portion of long-term debt, we had million and million in working capital at December 31, 2023 2022 , respectively, representing a million . The significant in working capital over the previous twelve months was due to decreases in the current portion of long-term debt, accounts payable, and accrued interest payable. The improvement was also due to a significant increase in cash from operations, accounts receivable, and inventory, as well as a 3 . Operating Risks Successful execution of our business strategy depends on several critical factors, including having adequate working capital, favorable refining margins, and consistent operations at the Nixon refinery. ● Working Capital – As noted above, we have historically had working capital deficits primarily due to having significant current debt. Sufficient working capital is necessary to meet contractual, operational, regulatory, and safety needs. Our short-term working capital needs are primarily related to (i) purchasing crude oil and condensate to operate the Nixon refinery, (ii) reimbursing LEH for direct operating expenses and paying the LEH operating fee under the Third ● Refining Margins – Refining margins, which are affected by commodity prices and refined product demand, are volatile, and a reduction in refining margins will adversely affect the amount of cash we will have available for working capital. Crude oil refining is primarily a margin-based business. To improve margins, we must maximize yields of higher-value finished petroleum products and minimize costs of feedstocks and operating expenses. Our margins are negatively affected when the spread between these commodity prices decreases. Although an increase or decrease in the commodity price for crude oil and other feedstocks generally results in a similar increase or decrease in commodity prices for finished petroleum products, typically, there is a time lag between the two. The effect of crude oil commodity price changes on our finished petroleum product commodity prices, therefore, depends, in part, on how quickly and how fully the market adjusts to reflect these changes. Unfavorable margins may ● Nixon Refinery Operation – We maintain relationships with suppliers that source and repair key components of the Nixon refinery. We expect our suppliers to maintain an adequate supply of component products and, when components are sent out for repair, to timely deliver components. However, in some cases, increases in demand or supply chain disruptions have led to part and component constraints. We use several suppliers and monitor supplier financial viability to mitigate supply-based risks that could cause a business disruption.
