In the process of demolishing and rebuilding office building restrooms, accounting guidance for related capitalized costs is clear, but how to classify the cost of renting portable toilet trailers during construction often sparks discussion. A peer asked: "Can someone point me to guidance on capitalizing costs incurred for renting portable toilets during the demolition and reconstruction of office building restrooms? The costs of demolishing and constructing old restrooms and building new ones are established, but the cost of renting portable toilet trailers during construction is less clear. If anyone has handled a similar office building project and can share their experience in handling temporary rental costs, I would be grateful."

This issue touches on the boundary between capitalization and expensing of subsequent expenditures on fixed assets. According to current accounting standards (such as Accounting Standards for Business Enterprises No. 4 - Fixed Assets and International Financial Reporting Standards (IAS 16)), subsequent expenditures related to fixed assets should be capitalized if they meet the recognition criteria (i.e., it is probable that future economic benefits will flow to the entity and the cost can be measured reliably); otherwise, they should be recognized in profit or loss when incurred. For the demolition and reconstruction of office building restrooms, if the expenditure extends the useful life of the asset, increases capacity, or significantly improves the asset's condition, it generally qualifies for capitalization. However, the cost of renting portable toilets during construction is more akin to a temporary expense incurred to maintain normal office operations, rather than a necessary expenditure directly attributable to bringing the asset to its intended usable condition.

From a practical perspective, there are two views on handling such rental costs. One view holds that if the rental of portable toilets is due to the original restrooms being unusable during construction, and the construction is a capitalization project, the rental cost can be considered part of the project's indirect costs and capitalized. Another view emphasizes that rental costs are period expenses because they do not directly increase asset value but are operational expenditures incurred to meet employees' basic physiological needs, and should be charged to administrative expenses or related period expenses.

To clarify this issue, we have reviewed relevant guidance. In the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC), there is no specific guidance on subsequent expenditures for fixed assets down to portable toilets, but the general principle is: if the expenditure extends the asset's useful life, increases capacity, or improves safety, it can be capitalized. Under International Financial Reporting Standards (IFRS), IAS 16 paragraph 13 states that subsequent costs are capitalized only if they meet the recognition criteria. Chinese accounting standards are similar. Therefore, the key to the judgment is: is the rental cost 'directly attributable' to the necessary expenditure to bring the restroom to its intended usable condition? Typically, temporary facility rentals (such as portable toilets) are not part of the asset's physical entity and do not directly enhance asset performance, so they tend to be expensed.

However, there are exceptions. If temporary sanitary facilities must be provided during construction due to safety or regulatory requirements, and the requirement is directly related to the capitalization project, some companies choose to allocate the rental cost to project costs. For example, if the construction contract explicitly requires the contractor to bear such costs, they may be included in construction-in-progress costs. But if borne by the owner, it is more likely to be treated as a period expense.

To help peers make decisions, we suggest referring to the following steps: First, assess whether the rental cost meets the capitalization criteria (i.e., whether it increases future economic benefits); second, check the company's accounting policies regarding the allocation of indirect costs; finally, consult auditors or tax advisors to ensure compliance. Additionally, if the project period is long and the rental cost is significant, consider using a systematic and reasonable method (such as based on construction progress) for allocation.

We welcome financial professionals with experience in similar office building projects to share specific handling methods. For example, whether to include portable toilet rental costs in 'Construction in Progress - Other Indirect Costs' or directly in 'Administrative Expenses - Temporary Facility Costs'? Different industries or companies of different sizes may have different practices. Your experience will help improve practical guidance in this area.

In summary, the choice between capitalization and expensing needs to be based on specific facts and judgment. In the absence of clear guidance, it is recommended to maintain consistency and fully disclose accounting policies in the notes to the financial statements. If there are still doubts, refer to relevant industry guidance or consult professional institutions.
