Internal controls

Habari Future Auditor! The Unseen Guard: Mastering Internal Controls

Welcome, Year 4! You are on the home stretch, and today we're tackling a topic that is the absolute backbone of auditing: Internal Controls. Think of it this way: a company is like a big, busy household. You have money (revenue), valuables (assets), and many people coming and going (employees, customers). How do you make sure nothing gets lost, stolen, or broken? You don't just hope for the best! You install locks, have rules about who can enter certain rooms, and maybe even have an 'askari' (guard). In the business world, these locks, rules, and guards are what we call internal controls.

Today, we will unpack this crucial concept, using examples you see every day here in Kenya, from the M-Pesa agent down the road to the biggest corporations in Nairobi. Tuko pamoja?

What Are Internal Controls, Really?

At its core, Internal Control is a process, a system of policies and procedures, put in place by a company's management to achieve its objectives. It’s not just about stopping fraud (though that’s a big part!). It’s about ensuring the entire business runs smoothly, efficiently, and honestly.

Real-World Scenario: The Supermarket Saga

Think about a busy supermarket like Naivas or Quickmart. Without controls, chaos would reign! Cashiers could give "discounts" to friends, stock could walk out the door without being paid for, and the accounting records would be a mess. Internal controls are the systems that prevent this: CCTV cameras, security guards at the exit checking receipts, managers authorising voids, and daily cash reconciliations at each till. They are the unseen engine that keeps the business profitable and secure.

The Main Goals: Why Bother with Controls?

Why does a company invest so much time and money into these systems? The primary objectives can be remembered with the acronym 'ROCS':

• Reliability of Financial Reporting: To ensure that the financial statements are accurate and trustworthy. Think about it, if you were to invest in a company on the Nairobi Securities Exchange (NSE), you need to trust their numbers!
• Operational Efficiency and Effectiveness: To make sure business processes run smoothly, without wasting time or resources (like money or inventory).
• Compliance with Laws and Regulations: To ensure the company follows the rules set by bodies like the Kenya Revenue Authority (KRA), the Central Bank of Kenya (CBK), or NEMA.
• Safeguarding of Assets: To protect the company's valuable assets (cash, equipment, inventory) from theft, damage, or misuse.

The style should be modern, clean, and use Kenyan flag colours subtly in the background.

The 5 Pillars of Control: The COSO Framework Simplified

A globally accepted model for internal controls is the COSO framework. Don't worry about the complex name! Just think of it as a house built on five strong pillars. If one pillar is weak, the whole house is at risk.

     THE 5 PILLARS OF INTERNAL CONTROL
+---------------------------------------------+
|               MONITORING                    |  <-- The Roof: Checking everything works
+---------------------------------------------+
|      INFORMATION & COMMUNICATION            |  <-- The Walls: Messages flow up, down, across
+---------------------------------------------+
|            CONTROL ACTIVITIES               |  <-- The Walls: The actual "doing" (actions)
+---------------------------------------------+
|              RISK ASSESSMENT                |  <-- The Walls: Identifying potential problems
+---------------------------------------------+
|           CONTROL ENVIRONMENT               |  <-- The Foundation: The "Tone at the Top"
+---------------------------------------------+

1. Control Environment: This is the foundation. It's the overall attitude and ethical values of the company, starting from the CEO. Is integrity valued, or is there a "chota-chota" (take a little here and there) culture?
2. Risk Assessment: This is where management identifies what could go wrong. For an M-Pesa agent, a risk is being robbed. For a flower farm, a risk is a disease wiping out the crop.
3. Control Activities: These are the specific actions taken to address the identified risks. This is the part we auditors test the most! We will look at these in more detail next.
4. Information & Communication: This ensures that important information is identified, captured, and communicated in a timely manner. For example, a junior accountant must know the procedure for reporting a suspicious transaction to their manager.
5. Monitoring: This is the process of checking whether the controls are working as intended over time. This is often done by internal auditors or through regular management reviews. Ni kama "kagua kazi"!

Let's Get Practical: Key Control Activities

These are the "boots on the ground" actions. Here are the most common ones you will encounter:

• Segregation of Duties (SOD): The golden rule! It means that no single person should have control over a transaction from start to finish. This is the "two-man rule".

  Kenyan Example: In a well-run SACCO, the person who approves a loan (Credit Officer) is different from the person who disburses the cash (Teller/Cashier), and a third person (Accountant) records it. This prevents one person from creating a fake loan and pocketing the money.

• Authorisation: Transactions must be properly authorised by someone with the appropriate level of authority. For example, a purchase of over KES 50,000 might require a signature from a Head of Department.
• Physical Controls: Securing physical assets. This includes locks, safes, security guards, fences, and CCTV cameras. Simple and effective!
• Reconciliations: This involves comparing two different sets of records to ensure they match. It's a powerful way to detect errors or fraud. The most common one is a bank reconciliation.

Calculation Corner: A Simple Petty Cash Reconciliation

Imagine you are the auditor for a small company. You decide to do a surprise cash count for their petty cash float. This is a classic test of controls. The float is supposed to be KES 10,000.

-------------------------------------------
PETTY CASH RECONCILIATION
-------------------------------------------
1. Petty Cash Float (Imprest Amount)  : KES 10,000.00

2. Cash Counted in the Box:
   - Notes: 4,500.00
   - Coins:   350.00
   ------------------
   Total Cash on Hand                  : KES  4,850.00 (A)

3. Review of Vouchers (Receipts for payments):
   - Voucher #001 (Transport)  : KES 1,200.00
   - Voucher #002 (Tea/Milk)   : KES   800.00
   - Voucher #003 (Airtime)    : KES 1,000.00
   - Voucher #004 (Stationery) : KES 2,100.00
   ------------------
   Total Vouchers                      : KES  5,100.00 (B)

4. Reconciliation:
   Total Accounted For (A + B)         : KES  4,850.00 + 5,100.00
                                       = KES  9,950.00

5. Conclusion:
   Float Amount                      : KES 10,000.00
   Total Accounted For               : KES  9,950.00
   -------------------------------------------------
   Shortage / (Surplus)              : KES     50.00  <-- AUDIT FINDING!
-------------------------------------------

This small KES 50 shortage might seem minor, but it's a breakdown in control! As an auditor, you would need to investigate why it happened.

No System is Perfect: The Inherent Limitations

Even the best internal control system can have weaknesses. It's crucial to remember these limitations:

• Human Error: A tired or careless employee can make a mistake that bypasses a control.
• Collusion: This is a big one. Two or more people can work together to override a control. For example, the procurement manager and a supplier can collude to inflate prices. Segregation of duties can't stop this.
• Management Override: A senior manager can use their authority to instruct a junior employee to ignore a control. This is very difficult to prevent.
• Cost vs. Benefit: A control might be too expensive to implement for the level of risk it addresses. You wouldn't build a KES 1 million vault to protect KES 10,000 of petty cash.

Your Turn to Think Like an Auditor!

We've covered a lot of ground, from the big picture objectives to the nitty-gritty of a petty cash count. Internal controls are not just a boring topic in a textbook; they are the living, breathing systems that protect businesses, ensure fairness, and build trust in our economy.

Food for Thought: The next time you go to pay a bill via M-Pesa, think about the controls involved. The agent asks for your ID (authorisation), you enter your secret PIN (access control), you both get a confirmation message (reconciliation data), and Safaricom's systems log the entire thing (information & communication). Controls are everywhere!

Keep asking "what could go wrong here?" and "what is in place to stop it?" and you'll be well on your way to thinking like a top-tier auditor. Well done today!
