The financial results of Flo are included in the Company’s consolidated statements of comprehensive income for the year-ended December 31, 2021, the consolidated statement of cash flow for the year-ended December 31, 2021 and the consolidated balance sheet as of December 31, 2021. The results of operations are included in the Plumbing segment. In December 2020, we acquired 100% of the outstanding equity of Larson Manufacturing ("Larson"), the North American market leading brand of storm, screen and security doors. Larson also sells related outdoor living products including retractable screens and porch windows. The acquisition of Larson is aligned with our strategic focus on the fast-growing outdoor living space. See Note 4 "Acquisitions and Dispositions," for additional information.
