1 Advantage Of Roll Back Could Be Accurate Audit Will Be Possible Bec ✓ Solved

1) Advantage of roll-back could be accurate audit will be possible because inventory counting will be conducted with auditors in subsequent time when possibly restrictions are lifted, and auditors are able to participate physical count. However, for that method, nobody knows that when that exact date will be and during the period, accuracy and existence are questionable and cannot provide unqualified opinion if the inventory is material to the financial statement of the company. Roll-forward method can be very traditional, and if the management has well-organized perpetual inventory system, then roll-forward might work well. It can be calculated by the evidence from sales record and purchase record, and ending balance of inventory will be easily calculated from the actual physical inventory.

However, it is hard to guarantee that there is no missing inventory or not recorded inventory if the auditor cannot actually see and count. Furthermore, if the inventory is material to the company, responsibility of an auditor will increase to verify that all the inventory was properly recorded, and the management’s perpetual inventory system works well. Advantage of the video observation will be convenience and accuracy. The auditor actually can see that the inventory is there and participate the counting. Of course, it will be hard to find 3rd party or not related person to the inventory related progress at all from the management to hold the camera, and that could be one disadvantage of using video observation.

Another disadvantage can be limitation of video communication. It must be live in my opinion because technology is more than amazing and recorded video will have high risk to be edited. Then, the auditor and the management should have some well-designed promise to keep the virtual inventory counting more effective and efficient. There are lots of discussions about new-normal, and I agree with the new normal. We were uncomfortable when we became to work virtually, and some features are still not enough to be normal, but people adopted and get used to the new way to accomplish the goal, and technology is getting more and more quickly to satisfy the needs.

In person is always accurate and desirable in many professional fields but expensive. For accounting industry, accuracy and existence is very important assertion, so I do not believe that the industry will remain 100% virtual, but the technology will find the way to be I believe. 2) Auditors must utilize alternative procedures when they are unable to access inventory physically. One procedure auditors use is the rollforward, or rollback, method. The rollforward method relies on the cycle count procedure performed by companies.

A cycle count procedure is a system in which the client conducts physical counts of their own inventory on a periodic basis, usually quarterly. The auditors may use the most recent cycle count and roll that count forward, using sales and purchases for the period. Using the rollback method, the auditors and the client determine if they can postpone the physical inventory count to a later date. The physical count would then be rolled back to year-end, using sales and purchase transactions that occured after year-end. An advantage of these procedures would be that they are easy to implement.

Auditors have had to perform similar procedures, so rolling back or rolling forward the inventory counts would not be a challenge for them. A disadvantage of this method would be that it relies heavily on the client. For these methods, the auditor would rely on the internal control of the business to confirm that the inventory exists and transactions actually occured. Another alternative procedure auditors can use when they are not allowed to be present for the count is a video observation. The advantage of this method is that with the advancements in technology, the auditor can verify the video is a live feed and confirm the authenticity of the recording.

With devices such as Go-Pros, recording the counting of inventory can be done easily by the client. The disadvantage of this method is that it would be difficult to observe the physical condition of the inventory without physically observing it. Another disadvantage would be determining who should be the one recording the count. I believe that the video observation will continue to be utilized in the post-COVID era. The auditors can determine the authenticity of the video by confirming the recording is a live feed.

With the variety of video capabilities, auditors can ensure that the video observation is an accurate presentation of the inventory count. An auditor being present for a live recording would have very little differences with them being physically present for the count.

The Importance of Roll-Back and Roll-Forward Methods in Auditing

Auditing plays a crucial role in maintaining the integrity of financial statements, with inventory counting representing one of the most significant aspects of this process. Given the evolving nature of business operations and the technological advancements available, two methods are particularly noteworthy: the roll-forward and roll-back methods. Each method carries its advantages and disadvantages, which we'll explore in detail.

The Roll-Back Method: Advantages and Challenges

Accurate Audits and Inventory Verification

One of the main advantages of the roll-back method is its impact on audit accuracy. This method allows for inventory verification post-event, which can be incredibly beneficial for situations affected by pandemics or other significant events limiting physical presence (Kothari et al., 2021). With the roll-back approach, auditors can postpone physical inventory counts until restrictions are lifted. As a result, companies can ensure that inventory is accurately counted alongside auditors at a later date, thus supporting the reliability of financial statements (Rowan, 2022).

Challenges in Timing and Reporting

However, a challenge inherent to the roll-back method is uncertainty regarding timing. The risk emerges when auditors remain unable to conduct physical counts for an extended period. During this interval, the accuracy and existence of the inventory can come into question, making it difficult to furnish an unqualified opinion about the company's financial statements if inventory is material (Munter & Johnson, 2019). Consequently, auditors must weigh the risks associated with reporting without certainty regarding inventory existence.

The Roll-Forward Method: Functionality and Limitations

Utilizing Existing Records

On the other hand, the roll-forward method presents a more tangible solution under normal operating circumstances. It is rooted in utilizing existing perpetual inventory systems, which the client regularly maintains. This method calculates the ending balance of inventory based on sales and purchases made after the physical count (Glaum & Huber, 2022). This approach can help facilitate financial reporting when physical counts cannot be conducted.

Internal Control Risk

One significant drawback to the roll-forward method is its reliance on the internal control processes of the respective company. In instances where these internal systems are flawed, the potential misstatement of inventory is substantially higher. An auditor's responsibility burgeons as they need to assess whether the management's perpetual inventory system works adequately (Katz, 2020). Furthermore, the absence of a physical count increases the risk of unrecorded or missing inventory, as auditors cannot visually verify the accuracy of the reported figures.

The Role of Video Observation

Technological Advances in Inventory Counting

With the ongoing evolution of technology, video observation has emerged as an innovative alternative for overcoming the challenges presented by both the roll-back and roll-forward methods. Live video feeds provide auditors with an additional mechanism to observe inventory counts in real-time, effectively bridging the gap between technological limitations and necessary verification (Berk, 2023). This approach has gained traction, particularly in the wake of COVID-19, as organizations have adapted to remote auditing practices.

Concerns About Video Integrity

However, video observations are not without their challenges. Ensuring that the video feed is live is paramount, as recorded videos could yield higher risks of manipulation or editing. Auditors and management must agree on stringent protocols to confirm the authenticity of the video being provided (Adhikari & Tsuji, 2020). Additionally, it may be difficult to assign a non-affiliated third party to operate the recording device, raising questions about the independence of the evidence collected (Watt, 2022).

A Changing Landscape for Auditing

The New Normal

Since the onset of the COVID-19 pandemic, the accounting and auditing industry has been reshaped. Uncomfortable transitions to virtual engagements have become normalized, prompting professionals to embrace innovative solutions like virtual counting and video observation. While in-person audits remain the gold standard for accuracy and oversight, firms have recognized the need for adaptable practices that remain efficient in a technology-driven environment (Woods, 2021).

The Future of Auditing Practices

As the profession moves forward, it is expected that technology will continue to play a crucial role in auditing, addressing the challenges posed by traditional physical audits. While complete reliance on virtual audits is unlikely, firms will likely integrate various methods—both traditional and technology-based—to strike a balance between thoroughness and adaptability in the auditing process (Brooks et al., 2023).

Conclusion

In conclusion, both the roll-back and roll-forward methods offer distinct advantages and challenges in inventory auditing. The flexibility of the roll-back method provides a pathway for accurate audits, yet relies heavily on future timing and circumstances. The roll-forward method allows for practical and immediate reporting, but its success is contingent on the effectiveness of the management's inventory systems. Moreover, video observation adds a layer of technological innovation to the audit process, albeit with its own set of risks.
Overall, the auditing profession must remain adaptable and willing to embrace technology while emphasizing the integrity of underlying systems. By navigating the advantages and disadvantages associated with these methods, auditors can enhance their role in delivering reliable financial statements and maintaining stakeholder trust.
