Interim Financial Statements

Brunswick's unaudited interim condensed consolidated financial statements have been prepared pursuant to SEC rules and regulations. Therefore, certain information and disclosures normally included in financial statements and related notes prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) have been condensed or omitted.
Fiscal Period Policy
The Company maintains its financial records on the basis of a fiscal year ending on December 31, with the fiscal quarters spanning approximately thirteen weeks. The first quarter ends on the Saturday closest to the end of the first thirteen-week period. The second and third quarters are thirteen weeks in duration and the fourth quarter is the remainder of the year. The second quarter of fiscal year 2026 ended on July 4, 2026, and the second quarter of fiscal year 2025 ended on June 28, 2025.
