Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	( 1 Organization Company Overview Blue Dolphin was formed in 1986 Assets are organized in two business segments: ‘refinery operations’ (owned by LE) and ‘tolling and terminaling services’ (owned by LRM and NPS). ‘Corporate and other’ includes Blue Dolphin subsidiaries BDPL (inactive pipeline and facilities assets), BDPC (inactive leasehold interests in oil and gas wells), and BDSC (administrative services).

An Affiliate also operates and manages all Blue Dolphin properties, funds working capital requirements during periods of working capital deficits, guarantees certain of our third 3 Going Concern Assessment Certain conditions and events were noted that initially caused management to evaluate our ability to continue as a going concern. These conditions and events include historical working capital deficits and significant current debt in default. We had positive working capital of million at March 31, 2024 compared to a working capital deficit of million at December 31, 2023 , representing a million improvement. March 31, 2024 December 31, 2023 March 31, 2024 Our current assets totaled March 31, 2024 December 31, 2023 , representing a $3.5 million increase. Our current liabilities totaled $52.5 March 31, 2024 December 31, 2023 , representing a $2.9 million decrease. Excluding the current portion of long-term debt, our current liabilities totaled $12.0 March 31, 2024 December 31, 2023 , representing a $4.0 million decrease.

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.

Net income for the three March 31, 2024 totaled million, or per share, compared to net income of million, or per share, for the three March 31, 2023 . The million, or per share, in net income between the periods resulted from less favorable refining margins on lower refinery throughput, production, and sales volumes. We cannot assure investors that refining margins will remain positive and demand will increase. Working Capital Improvements We had working capital o f million at March 31, 2024 and a working capital deficit of million at December 31, 2023 , representing a million improvement. Excluding the current portion of long-term debt, we had $40.9 million and $33.3 million in working capital at March 31, 2024 and December 31, 2023 , respectively, representing a $7.6 million increase. The significant increase in working capital between the periods w Operating Risks Successful execution of our business strategy depends on several critical factors, including having adequate working capital, favorable refining margins, and maintaining operation of the Nixon refinery. ● Working Capital ● Refining Margins may ● Nixon Refinery Operation General macroeconomic conditions related to inflation, interest rates, and capital and credit markets, geopolitical tensions, including military conflicts in Ukraine and Israel and escalations in the Middle East, and COVID- 19 no third may
