Introduction: Why Can't We Do It All Alone?
Welcome to one of the most practical chapters in your Audit and Assurance (AA) journey! Imagine you are tasked with auditing a massive jewelry business. You are an expert at counting money and checking invoices, but do you know exactly how to tell the difference between a real diamond and a piece of high-quality glass? Probably not!
In the world of auditing, we often need a helping hand. This chapter explains how we can use the work of others while still making sure our audit opinion is solid as a rock. We will look at two main groups: Internal Auditors and Auditor’s Experts. Don't worry if this seems a bit technical at first—we'll break it down into simple, everyday steps!
1. Using the Work of Internal Auditors (ISA 610)
Most large companies have their own "in-house" auditors called Internal Auditors. They work for the company to check its systems and controls. As external auditors, we might be able to use their work to save time and effort. However, we can't just take their word for it!
How do we decide if we can use their work?
Before you trust someone else's homework, you’d check if they are good at the subject, right? We do the same here. We evaluate the Internal Audit (IA) function based on three main pillars:
1. Objectivity: Are they truly independent? If the internal auditor reports to the Accountant they are checking, they might not be honest. They should ideally report to the Audit Committee.
2. Technical Competence: Do they have the right qualifications and experience? Are they members of a professional body?
3. Systematic and Disciplined Approach: Do they have a clear plan? Do they document their work properly? If their files are a mess, we can't rely on them.
Quick Review Box:
Think of the internal audit team as a "security guard" hired by a building owner. As the "Police" (External Auditor), you can use the guard's logs, but you must first check if the guard is well-trained, follows the rules, and isn't best friends with the burglars!
What work can we use?
We can use their work on things like testing of controls or observing inventory counts. However, we should not use their work for areas that involve a lot of judgment or have a very high risk of material misstatement.
Example: We might let them help count the boxes in the warehouse, but we won't let them decide how much "bad debt" the company should write off.
Direct Assistance
Sometimes, we might ask the internal auditors to work directly under our supervision. This is called "Direct Assistance."
Common Mistake to Avoid: Not all countries allow Direct Assistance! Also, the external auditor must still review the work and take full responsibility. You cannot ask them to do work that involves significant judgment.
Key Takeaway: Before using Internal Audit work, evaluate their Objectivity, Competence, and Processes. The external auditor is still 100% responsible for the audit opinion!
2. Using the Work of an Auditor’s Expert (ISA 620)
As auditors, we are experts in accounting and auditing—not necessarily in engineering, geology, or art appraisal. This is where an Auditor's Expert comes in.
Who is an "Expert"?
An expert is a person or firm possessing skill, knowledge, and experience in a field other than accounting or auditing.
Examples:
- An actuary to calculate pension liabilities.
- A surveyor to value land and buildings.
- A lawyer to estimate the likely outcome of a big lawsuit.
Evaluating the Expert (The "CCO" Check)
Before we hire or use an expert, we must check three things:
1. Competence: Do they have the professional qualifications and experience?
2. Capability: Do they have the resources (time and staff) to do the job?
3. Objectivity: Are they independent of the client? If the expert is the CEO’s brother, we have a problem!
Evaluating the Expert’s Work
Once the expert gives us their report, we can't just file it away. We must check if it makes sense. We should:
- Check the source data they used (is it accurate?).
- Check the assumptions they made (are they reasonable?).
- Ensure their findings are consistent with other audit evidence we have found.
Memory Aid: "CCO"
To remember what to check for an expert, remember CCO: Competence, Capability, and Objectivity.
Did you know?
If the expert’s work is not adequate, we can't just give up. We must either ask the expert to do more work or hire another expert to get a second opinion!
Key Takeaway: The auditor needs to assess the expert's Competence, Capability, and Objectivity and must critically review the assumptions and data used in the expert's report.
3. Important: Responsibility and Reporting
This is a favorite topic for exam questions! Students often get confused about who is "to blame" if something goes wrong.
The Golden Rule: The External Auditor has sole responsibility for the audit opinion. You cannot blame the Internal Auditor or the Expert if you miss a mistake in the financial statements.
Mentioning the Expert in the Audit Report:
- Usually, we do not mention the expert in an "unmodified" (clean) audit report.
- We only mention them if it’s required by law or if it helps explain why we are "modifying" (changing) our audit opinion. Even then, we must state that their mention doesn't reduce our responsibility.
Quick Summary Table:
Internal Audit: Hired by the client. We check their objectivity and competence before using their work.
Auditor's Expert: Hired by the auditor (or client) for specialist knowledge. We check their "CCO" and review their assumptions.
Final Summary and Tips for the Exam
1. Don't be a "Passive" Auditor: Whenever you use the work of others, you must be skeptical. Always ask: "Is this person biased?" and "Does this work actually make sense?"
2. Focus on Risk: In exam scenarios, if the area is high-risk (like valuing a brand-new technology), you should do more work yourself and rely less on others.
3. Responsibility: Always remember—the auditor signs the report, so the auditor takes the blame. You can't pass the buck!
Don't worry if this seems like a lot to remember! Just keep thinking about the "Security Guard" and the "Specialist Doctor" analogies, and you'll do great. You've got this!
