6-K/A
Annual Report Classification · 95% confidence The document is a Form 6-K/A filed by Atlas Corp., which is a report of a foreign private issuer pursuant to the Securities Exchange Act of 1934. It amends a previously filed Form 6-K to correct the auditor's report paragraph. The document contains audited consolidated financial statements of Seaspan Corporation, a wholly owned subsidiary, for the year ended December 31, 2023, including balance sheets, statements of operations, comprehensive income, and shareholder's equity. The presence of full audited financial statements and the auditor's report indicates this is a comprehensive financial report. Form 6-K filings are typically used by foreign private issuers to furnish reports similar to interim or annual reports. Given the detailed financial statements for a full fiscal year and the auditor's opinion, this filing corresponds to an Annual Report equivalent for a foreign issuer. Therefore, the appropriate classification is Annual Report (10-K).

The document is not an announcement or a certification but contains substantive financial data and analysis for the quarter. Therefore, the appropriate classification is Interim / Quarterly Report (IR).
