Segment Reporting [Abstract]  
Segment Reporting
(7) Segment Reporting
Each geographic region (U.S., Canada, Mexico, Central & South America, Europe, Asia, and SE Asia) is engaged in business activities for which it may earn sales and incur expenses. Discrete financial information is available at the geographic region level through our internal Return on Assets (ROA) reporting. The ROA reporting is a selling location income statement with an ROA calculation and the results are compiled by geographic region. ROA pre-tax profit measures financial performance and drives compensation programs.
Through July 16, 2026, our Chief Operating Decision Maker (CODM) was a group consisting of our Chief Executive Officer (CEO) and our President/Chief Sales Officer. Effective July 16, 2026, our President and CEO became our sole CODM. We consider each geographic region to be an operating segment. The CODM regularly reviews ROA pre-tax profit to make decisions about the allocation of resources at the geographic region level. Operating segment significant expense categories and amounts are not regularly reviewed by or provided to our CODM. Segment expenses represent the difference between net sales and ROA pre-tax profit and consist of cost of sales and selling, general, and administrative (SG&A) expenses. However, our CODM reviews consolidated expense information to manage the operations of the business.
Considering our operating segments outside of the U.S. individually represent less than 10% of our total operating segment net sales, ROA pre-tax profit, and ROA assets, we do not consider them reportable segments. Therefore, we report the results of our one reportable segment (U.S.) below. Further details on our significant accounting policies can be found in Note 1 of our most recently filed annual report on Form 10-K, which are applied companywide.
Our segment measure of profit or loss is ROA pre-tax profit and our measure of assets is ROA assets. ROA pre-tax profit is not a financial measure calculated in accordance with GAAP and excludes inter-company transactions.
