## Definition
内部控制Internal Controls是企业为确保财务报告可靠性、运营效率和合规性而建立的政策和程序体系。
## Control Design Components
- **Authorization Matrices**:授权矩阵,定义谁有权批准哪些类型的交易
- **Approval Workflows**:审批工作流,确保所有重大交易经过适当审批
- **System Access Controls**:系统访问控制,限制对敏感财务系统的访问
- **Data Validation Rules**:数据验证规则,防止无效或未经授权的数据进入系统
## Control Monitoring
- 关键控制测试
- 例外情况跟踪
- 整改管理
## SOX Compliance
萨班斯-奥克斯利法案SOX对公众公司的内部控制提出了强制性要求
- 控制文档化
- 测试计划
- 缺陷跟踪
- 管理层声明
## Segregation of Duties
职责分离是内部控制的核心原则:
- 交易发起人 ≠ 审批人
- 交易审批人 ≠ 记录人
> "The person who initiates a transaction should not be the same person who approves or records it."
## Policy Maintenance
- 会计政策文档化
- 程序手册维护
- 授权矩阵更新
## Core Principle
> "Internal controls exist because humans make mistakes (and occasionally worse). Trust but verify — then verify again."
> — Dana, Bookkeeper & Controller Agent
## Success Metrics
- 内部控制例外率 < 3%
- 所有控制按测试计划执行
- 零 SOX 重大缺陷
