Accounting Policies [Abstract] |
Accounting principles | The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") on a basis consistent with that used in the Annual Report on Form 10-K for the year ended August 31, 2020 ("2020 Form 10-K") filed by Commercial Metals Company ("CMC," and together with its consolidated subsidiaries, the "Company") with the Securities and Exchange Commission (the "SEC") and include all normal recurring adjustments necessary to present fairly the condensed consolidated balance sheets and the condensed consolidated statements of earnings, comprehensive income, cash flows and stockholders' equity for the periods indicated. These notes should be read in conjunction with the consolidated financial statements included in the 2020 Form 10-K. The results of operations for the three month period are not necessarily indicative of the results to be expected for the full fiscal year. Any reference in this Form 10-Q to a year refers to the fiscal year ended August 31st of that year, unless otherwise noted.
Recent accounting pronouncements | Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12"). ASU 2019-12 eliminates certain exceptions to the general principles in Accounting Standards Codification 740 and also clarifies and amends existing guidance to improve consistent application. The Company adopted ASU 2019-12 on September 1, 2020. ASU 2019-12 did not have a material effect on the Company's condensed consolidated financial statements.
Fair value measurement | The Company has established a fair value hierarchy which prioritizes the inputs to the valuation techniques used to measure fair value into three levels. These levels are determined based on the lowest level input that is significant to the fair value measurement. Levels within the hierarchy are defined within the Summary of Significant Accounting Policies footnote in our 2020 Form 10-K.
