Transparent financial reporting depends on more than accurate top-line numbers. Investors, lenders, and other capital providers rely on financial statements to evaluate a company’s performance, assess its prospects for future cash flows, and benchmark it against peers, and a critical part of that evaluation is understanding what actually makes up a company’s expenses. Expense composition reveals cost structure, operational efficiency, and long-term sustainability in ways that a single aggregated number cannot.<\/span><\/p>\n

Historically, U.S. GAAP did not require consistent disaggregation of income statement expenses, which left companies free to report at very different levels of detail. That inconsistency made it genuinely difficult for investors and analysts to compare financial results across entities and industries, since one company’s “operating expenses” line might hide detail another company discloses openly. This is the gap DISE, the Disaggregation of Income Statement Expenses requirement, was built to close.<\/span><\/p>\n

How DISE Came to Be<\/h3>\n

FASB first addressed this gap in July 2023, introducing a proposed Accounting Standards Update titled Income Statement, Reporting Comprehensive Income, Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. After gathering extensive feedback through public comment periods and roundtable discussions with preparers, investors, and auditors, FASB finalized the amendments as ASU 2024-03 in November 2024.<\/span><\/p>\n

The goal is straightforward: enhance the decision-usefulness of financial reporting by requiring companies to disclose disaggregated expense detail within the footnotes of their financial statements, giving users of financial statements a clearer view of cost composition than aggregated income statement line items alone can provide.<\/span><\/p>\n

ASU 2025-01: Clarifying When DISE Actually Applies<\/h3>\n

In January 2025, FASB issued ASU 2025-01, Income Statement, Reporting Comprehensive Income, Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. This update did not change the substance of the disaggregation requirement itself. It resolved confusion about exactly when the requirement takes effect, particularly around how it applies to interim reporting periods.<\/span><\/p>\n
