Accounting Policies [Abstract] |
Basis of Presentation | A. Basis of Presentation The consolidated financial statements have been prepared in conformity with accounting policies generally accepted in the United States (“U.S.”) and include the accounts of Cabot Corporation (“Cabot” or the “Company”) and its wholly-owned subsidiaries and majority-owned and controlled U.S. and non-U.S. subsidiaries. Additionally, Cabot considers consolidation of entities over which control is achieved through means other than voting rights. Intercompany transactions have been eliminated in consolidation. The unaudited consolidated financial statements have been prepared in accordance with the requirements of Form 10-Q and consequently do not include all disclosures required by Form 10-K. Additional information may be obtained by referring to Cabot’s Annual Report on Form 10-K for its fiscal year ended September 30, 2021 (“2021 10-K”). The financial information submitted herewith is unaudited and reflects all adjustments which are, in the opinion of management, necessary to provide a fair statement of the results for the interim periods ended March 31, 2022 and 2021. All such adjustments are of a normal recurring nature. The results for interim periods are not necessarily indicative of the results to be expected for the fiscal year. As discussed in Note C, on February 28, 2022, the Company acquired Tokai Carbon (Tianjin) Co. (“Tokai Carbon”). The results of operations and cash flows of Tokai Carbon are included in the Company’s consolidated financial statements from the date of acquisition. As discussed in Note D, on March 1, 2022, the Company completed the sale of its Purification Solutions business to an affiliate of funds advised by One Equity Partners (“OEP”). The sale of the Purification Solutions business did not meet the criteria to be reported as a discontinued operation as it did not constitute a significant strategic business shift for the Company, and has no major effect on operations. Therefore, prior periods’ consolidated financial statements and disclosures have not been retroactively restated to reflect the impact of the sale of the Purification Solutions business.
