Answer: less detailed than their revenue disclosures.

## Explanation In financial reporting, issuers typically provide **less detailed disclosures about operating costs** compared to revenue disclosures. This is because: 1. **Revenue recognition** is a critical area with complex accounting standards (such as ASC 606/IFRS 15) that require detailed disclosure about revenue streams, contract terms, performance obligations, and disaggregation of revenue. 2. **Operating costs** are often aggregated into broader categories (like cost of goods sold, selling, general and administrative expenses) without the same level of granularity required for revenue. 3. **Regulatory requirements** focus more on revenue transparency due to its importance in assessing a company's core business performance and potential for manipulation. 4. **Competitive considerations** - companies may be reluctant to disclose detailed cost structures that could reveal competitive advantages or disadvantages. Therefore, option A is correct: operating cost disclosures are most likely less detailed than revenue disclosures.
