Notes to Financial Statements
Significant Accounting Policies [Text Block]	1. Basis of Presentation: The accompanying Unaudited Consolidated Financial Statements have been prepared from the financial records of Olympic Steel, Inc. and its wholly-owned subsidiaries (collectively, Olympic or the Company), without audit and reflect all normal and recurring adjustments which are, in the opinion of management, necessary to fairly state the results of the interim periods covered by this report. Year-to-date results are not necessarily indicative of 2020 annual results and these Unaudited Consolidated Financial Statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. All intercompany transactions and balances have been eliminated in consolidation. The Company operates in three reportable segments; carbon flat products, specialty metals flat products, and tubular and pipe products. The carbon flat products segment and the specialty metals flat products segment are at times consolidated and referred to as the flat products segments. Certain of the flat products segments’ assets and resources are shared by the carbon and specialty metals flat products segments, and both segments’ products are stored in the shared facilities and, in some locations, processed on shared equipment. Due to the shared assets and resources, certain of the flat products segment expenses are allocated between the carbon flat products segment and the specialty metals flat products segment based upon an established allocation methodology. The carbon flat products segment sells and distributes large volumes of processed carbon and coated flat-rolled sheet, coil and plate products, and fabricated parts. Through its acquisition of McCullough Industries (McCullough) on January 2, 2019, the carbon flat products segment expanded its product offerings to include self-dumping metal hoppers and through its acquisition of certain assets related to the manufacturing of the EZ-Dumper® hydraulic dump inserts (EZ Dumper) on August 5, 2019, to include steel and stainless-steel dump inserts for pickup truck and service truck beds. The specialty metals flat products segment sells and distributes processed aluminum and stainless flat-rolled sheet and coil products, flat bar products and fabricated parts. Through its acquisition of Berlin Metals, LLC (Berlin Metals) on April 2, 2018, the specialty metals flat products segment expanded its product offerings to include differing types of stainless flat-rolled sheet and coil and prime tin mill products. The tubular and pipe products segment, which consists of the Chicago Tube and Iron subsidiary (CTI), distributes metal tubing, pipe, bar, valves and fittings and fabricates pressure parts supplied to various industrial markets. Corporate expenses are reported as a separate line item for segment reporting purposes. Corporate expenses include the unallocated expenses related to managing the entire Company (i.e., all three segments), including payroll expenses for certain personnel, expenses related to being a publicly traded entity such as board of directors’ expenses, audit expenses, and various other professional fees. On March 11, 2020, the World Health Organization classified the novel coronavirus (COVID-19) outbreak as a pandemic. The pandemic had a significant impact on the Company’s Consolidated Financial Statements for the nine months ended September 30, 2020, resulting in lower sales and a net loss for the year. The Company is an essential business and remains open in all locations, adhering to all health guidelines to operate safely provided by the Center for Disease Control and Prevention and local authorities. The COVID-19 pandemic had and could continue to have material and adverse effects on our financial condition, results of operations and cash flows in the near term due to, but not limited to, (i) reduced sales and profit levels, (ii) the slower payment of accounts receivable and potential increases in uncollectible accounts receivable, (iii) falling metals prices that could lead to lower of cost or net realizable value inventory adjustments and the impairment of intangible and long-lived assets, (v) reduced availability and productivity of our employees, (vi) increased operational risks as a result of remote work arrangements, including the potential effects on internal controls, as well as cybersecurity risks and increased vulnerability to security breaches, information technology disruptions and other similar events, (vii) negative impacts on our liquidity position, (viii) inability to access our traditional financing sources on the same or reasonably similar terms as were available before the COVID-19 pandemic, and (ix) increased costs and less ability to access funds under our ABL Credit Facility (as defined below in Note 7) and the capital markets. The Company has implemented actions to maintain its financial health and liquidity. The Company continues to closely monitor the impact of the COVID-19 pandemic on all aspects of its business. However, as a result of the many uncertainties surrounding the COVID-19 pandemic, we are unable to predict the impact that it ultimately will have on its financial condition, results of operations, comprehensive loss, and cash flows. Impact of Recently Issued Accounting Pronouncements In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments-Credit Losses (Topic 326)”, which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. The ASU replaces the existing incurred loss impairment model with a forward-looking expected credit loss model which will result in earlier recognition of credit losses. The adoption of this ASU on January 1, 2020, did not have a material impact on the Company’s Consolidated Financial Statements.
