## Internal Control
### Meaning
Internal Control is a process:
- Designed and maintained by Management (TCWG)
- Provides Reasonable Assurance (not absolute assurance)
- Directed toward achieving the entity's objectives
> Key phrase: Reasonable Assurance — internal control has inherent limitations and cannot guarantee complete absence of misstatement.
### Objectives of Internal Control
| Objective | Description |
|---|---|
| Reliability of Financial Reporting | Financial statements are accurate and complete |
| Effectiveness & Efficiency of Operations | Resources used optimally to achieve goals |
| Safeguarding of Assets | Protection from theft, misuse, or loss |
| Compliance with Laws & Regulations | Adherence to applicable legal requirements |

### Benefits of Internal Control (for the Auditor)
1. Helps identify types of potential misstatements
2. Helps identify factors that affect ROMM
3. Helps design Nature, Timing & Extent of Further Audit Procedures
### Practical Illustration: Purchase Process
A controlled purchase cycle demonstrates segregation of duties:
```
Warehouse Dept → sends requisition → Purchase Dept
Purchase Dept → orders goods from → Vendor
Vendor → delivers to → Factory Gate (authorized person verifies)
If correct → Invoice to Payment Dept; Goods to Warehouse
Payment Dept → pays Vendor
```
No single department handles the full transaction — this is segregation of duties, a fundamental internal control principle.
