  4. Check subsequent events: Post-period events may be material.
  5. Cross-reference MD&A: Management discussion provides context.
  6. Note judgmental areas: High-estimate disclosures signal risk.
  1. 从附注1开始：重大政策摘要为分析提供基础。
  2. 跟踪变更：对比年度间脚注，发现政策变化。
  3. 阅读关联方交易：与内部人员的交易揭示治理情况。
  4. 查看期后事项：报告期后事件可能具有重要性。
  5. 交叉参考MD&A：管理层讨论与分析提供背景信息。
  6. 关注高判断领域：高估计披露意味着风险。
