Change in Accounting Estimate

What is Change in Accounting Estimate?

A change in accounting estimate occurs when there is the appearance of new information, which replaces the existing information based on which the company had taken an earlier decision, resulting in two things – changing the carrying amount of an existing asset or liability and alteration of subsequent accounting for recognition of future assets and liabilities.

Examples of Change in Accounting Estimate

While accounting for the transactions, we need to take into consideration the number of estimates or use our prudence or judgment. In some cases, these estimates can prove to be inappropriate, as the basis on which we had taken our assumption, has changed. To keep our books align with the subsequent changes, it warrants for change in accounting estimate.

In the following situation, we use our prudence

This is not an exhaustive list and it would expand depending upon the sector in which the business is involved.

Numerical Example

ACE Inc, bought a chemical plant amounting to $400 mn on January 1, 2016. At the time of recognition of plant as a fixed asset, the company estimated its useful life to be 10 years and salvage value $80 mn.

The company used the Straight Line Method for depreciating the assets.

On January 1, 2019, the company ought to know that the salvage value of the plant has decreased to $60 mn and life to 8 years, due to new technology being introduced in the market.

Calculation

• From 2016 to 2018, the company would have recorded depreciation of $32 mn per annum, {(400-80)/10}.
• The book value as on January 1, 2019, would be $336 mn. ($400-$32-$32).
• Due to new technology in the market,
• Now the revised depreciation would be $35 mn {(336-60)}/8}.

Please note that the change in estimate affects subsequent periods only and not the historical book values.

Change in Accounting Policy and Estimate is Not the Same

A change in accounting policy governs how the financial information would be calculated, wherein a change in accounting estimate is a change in the valuation of financial information.

The best example of a change in accounting policy is the inventory valuation. The company is using First in, First Out (FIFO) method as the valuation of the stock. Due to the requirement of the law, now the company has to use Last In, First Out (LIFO) method as the stock valuation.

In the accounting estimate, the company was using the Straight Line Method to depreciate the asset and it has estimated salvage value of the asset as $3,000. But due to changes in the market scenario, now the company can fetch only $1,000 of its asset.

Due to this, the depreciable value would alter, resulting in a change in accounting estimate. In case, the company would have changed the Straight Line Method to Written Down Value, then it would be classified as a change in accounting policy.

Is a Change in Accounting Estimate Equivalent to Error?

An error is one that happens unintentionally, and change in estimates would not fall under this category.

Estimates are based on certain assumptions and theories and when it changes according to the scenario, then we need to alter the basis. It does not tantamount to error or omission.

Once an error is identified, we need to assess the appropriate means to rectify the error.

There are three things to be considered when we identify the omission in the financial statements –

• Determining if the error exists and it is not changed in accounting estimate or principle
• Assessing the materiality of the error, keeping in mind the revenue or turnover of the company.
• Reporting an error in the previously issued financial statements.

So, there is a thin line of difference between error and change in estimate. It would involve the judgment and experience of the management involved.

Internal Controls on Changes in Accounting Estimates

Financial statement risks related to changes in accounting estimates must be properly mitigated by the proper internal controls placed by the management.

Management should understand the significant assumptions and methods used and ensure that unnecessary changes are timely identified by the controls to prevent harm to the interests of stakeholders.

A company should try the following to ensure stringent control on change in the accounting estimates

• Communication flow should be proper and flawless.
• A qualified person should be handed this task for alteration, whenever required.
• A comparison between pre and post-change of the estimate should be listed out, which would help the stakeholders to make informed decisions.

How Should an Investor Look at Estimates?

An investor needs to ensure that the financial position of the company is free from bias, errors and wrong assumptions.

He should be able to ask the following questions while deciding to invest in the company –

• Whether the rate of depreciation, if taken more than the permissible limit of the law, is in line with the usage of the assets?
• Is the provision of bad debts inflated or deflated to temper with the profits of the company?
• Is the useful life of the fixed asset proper?

Though it may seem difficult for an investor to deep-dive in such type of questions, the actual position of the company lies in this pothole only.

Disclosure of Change in Accounting Estimates

The entity should disclose the following in the financial statements-

• Nature and amount of change in an accounting estimate that has an effect in the current period or has an effect in the future periods
• If it is impracticable to determine the effect in future periods, then suitable disclosure should be provided in the notes to accounts.

Conclusion

There are different and less stringent compliances when it comes to change in accounting estimate over the change in principle. The latter needs to be changed retrospectively whereas the former to be prospective.

In some cases, one can find that the change in accounting principle may lead to a change in accounting estimate. In such cases, reporting and disclosure requirements of both change in principle and estimate should be followed.
