In 2021, we launched and committed resources to a program designed to accelerate growth and drive margin expansion through transformation of our business model to drive operational excellence, reduce complexity and streamline our processes (the “Transformation Program”). The Transformation Program is structured in multiple phases and is expected to empower us to work more efficiently and optimize our business to better serve our customers while meeting our financial objectives.

During 2023, 2022 and 2021, we initiated and continued execution of our Transformation Program as well as certain business restructuring initiatives aimed at reducing our fixed cost structure and realigning our business. Restructuring and Transformation Program initiatives during the years ended December 31, 2023, 2022 and 2021 included a reduction in hourly and salaried headcount of approximately 475 employees, 625 employees and 75 employees, respectively.

Restructuring and transformation-related costs included within Cost of goods sold and Selling, general and administrative expenses in the Consolidated Statements of Operations and Comprehensive Income included the following:
