Selling, general, and administrative expenses (SG&A) in a company's income statement encompass all general and administrative expenses (G&A) along with both direct and indirect selling expenses of the business. We differentiate between two versions of this expense category: SG&A and SG&A_GAAP. The former includes most operational costs not directly tied to the creation of a product or the execution of a service, excluding Research and Development (R&D) expenses. In contrast, SG&A_GAAP, adhering to Generally Accepted Accounting Principles (GAAP), integrates R&D expenses, providing a comprehensive overview of a company's operational expenditures.
The choice between SG&A and SG&A_GAAP depends on the analytical focus: SG&A offers a view excluding R&D for strategies prioritizing direct operational costs, while SG&A_GAAP provides a fuller picture of all operational expenses, including R&D.
