A Guide to Complying with the IAS 16 – Property, Plant and Equipment

Accurate accounting for Plant, Property, and Equipment (PP&E) is crucial for organizations to effectively manage their assets and comply with International Financial Reporting Standards (IFRS). The IFRS component approach provides a comprehensive framework for recognizing, measuring, and reporting PP&E components. 

This article aims to provide a practical guide to understanding and implementing the IFRS component approach for accounting professionals and finance teams.


What Is Asset Componentization?

Asset componentization refers to the process of breaking down a single asset into its individual components for accounting and reporting purposes. It involves recognizing and separately measuring significant components or parts of an asset, rather than treating the entire asset as a single entity. This approach allows for more accurate and detailed accounting, as each component may have different useful lives, depreciation rates, and valuation methods.

By componentizing assets, organizations can better reflect the economic reality of their assets and provide more transparent financial information. It also enables better decision-making by facilitating a more precise assessment of the value, useful life, and potential impairment of each component.

Asset componentization is commonly applied in various areas, such as plant, property, and equipment (PP&E), where assets comprise distinct parts that may have different characteristics. It is particularly relevant when complying with accounting standards, such as the International Financial Reporting Standards (IFRS), that emphasize component-based accounting to provide a more accurate representation of an entity’s financial position

How to recognize and measure individual components under IAS 16 (IFRS)?

Recognizing and measuring individual components under International Financial Reporting Standards (IFRS) involves several steps. 

Below are steps of a general guide on how to recognize and measure components:

Identify significant components

Identify the distinct parts or components of the asset that are significant in relation to the total cost of the asset and have different useful lives. Examples may include major machinery, building structures, or specific equipment within a larger asset.

Separate recognition

Recognize each significant component as a separate asset. Assign a cost to each component, which includes the purchase price and directly attributable costs such as installation or transportation

Initial measurement

Measure each component separately based on its individual cost. This involves determining the cost incurred to acquire or construct the component, including any directly attributable costs. The cost can be measured using historical cost, fair value, or other appropriate valuation methods.

Subsequent measurement

Determine the subsequent measurement basis for each component. The two common measurement models under IFRS are the cost model and the revaluation model. Under the cost model, components are measured at historical cost less accumulated depreciation and any accumulated impairment losses. The revaluation model allows components to be measured at fair value less accumulated depreciation and any accumulated impairment losses, but it requires regular revaluations.


Calculate depreciation for each component based on its estimated useful life, residual value, and chosen depreciation method. Each component may have a different useful life, and therefore, depreciation should be calculated separately for each one.


Perform impairment assessments for each component individually. If there are indications of impairment, test each component for recoverability. If impairment exists, recognize the impairment loss separately for each impaired component.

Disclosure requirements

Provide comprehensive disclosures related to the recognition and measurement of individual components. Disclosures should include information about the significant components, measurement bases applied, carrying amounts, depreciation methods used, and any impairments or revaluations undertaken.

How do I determine the useful life and depreciation method for each component?

Determining the useful life and depreciation method for each component under IAS 16 (IFRS) involves a careful assessment of several factors. Here’s a general approach to determining these aspects:

  • Useful Life: The useful life of each component should be estimated based on factors such as
    • The expected physical wear and tear or obsolescence of the component.
    • Technological advancements that may render the component obsolete.
    • Legal or contractual limits on the use of the component.
    • The expected demand for the component.

What else is important to consider when estimating the useful life? 

It’s important to consider industry-specific guidelines, historical data, expert opinions, and internal knowledge when estimating the useful life. Each component may have a different useful life, so it’s crucial to evaluate them individually.

  • Depreciation Method: The depreciation method should reflect the pattern in which the component’s future economic benefits are expected to be consumed. Common depreciation methods include:
    • Straight-line method: Allocates the depreciable amount of the component evenly over its useful life.
    • Diminishing balance method: Applies a higher depreciation rate to the component’s carrying amount in the earlier years, reflecting a higher rate of consumption.
    • Units of production method: Allocates the depreciable amount based on the actual usage or production of the component.

How should we base the selection of the depreciation method?

The selection of the depreciation method should be based on the nature of the component, its expected pattern of consumption, and industry practices. It’s important to ensure that the chosen method is applied consistently over the component’s useful life. 

Additionally, it’s crucial to review and reassess the estimated useful life and depreciation method regularly, especially if there are significant changes in the component’s performance, usage, or economic factors affecting its value.

Remember, the determination of useful life and depreciation method requires professional judgment and should be supported by reasonable and supportable assumptions and analysis. Consulting with accounting experts and considering industry-specific guidance can also provide valuable insights in making these assessments.

You must be wondering: Are there any specific guidelines or considerations for impairments of individual components?

The answer is yes, here are specific guidelines and considerations for impairments of individual components under IAS 16 (IFRS). When assessing impairments for each component, the following guidelines should be considered:

  1. Indicators of Impairment: Review for indicators that may suggest an asset component is impaired. These indicators include physical damage, significant changes in technology, market conditions, legal or regulatory changes, or a significant decrease in the asset’s market value.
  2. Recoverable Amount: Determine the recoverable amount for each impaired component. The recoverable amount is the higher of an asset’s fair value less costs of disposal or its value in use. Fair value can be determined through market prices, valuation techniques, or recent comparable transactions. Value in use is the present value of estimated future cash flows generated by the asset.
  3. Impairment Loss: Calculate the impairment loss for each impaired component. If the carrying amount (cost less accumulated depreciation) of a component exceeds its recoverable amount, an impairment loss should be recognized. The impairment loss is the difference between the carrying amount and the recoverable amount.
  4. Allocation of Impairment Loss: Allocate the impairment loss to the impaired component. The loss should be allocated to the specific component based on its carrying amount relative to the carrying amounts of other components within the same asset. This ensures that the impairment loss is appropriately recognized at the component level.

How does the Component Approach enhance financial reporting and decision-making compared to other methods?

The Component Approach, as outlined in IAS 16, enhances financial reporting and decision-making by providing a more accurate and detailed representation of an entity’s assets. It achieves the following benefits:

  • Transparency and Accuracy: The Component Approach breaks down assets into individual components, providing a transparent view of their composition and value. This avoids lumping together different components with varying characteristics, useful lives, and depreciation rates, leading to more accurate financial statements.
  • Granular Asset Information: The Component Approach provides detailed information about each component, including cost, useful life, depreciation method, and potential impairments. This facilitates better decision-making by providing insights into maintenance, replacement, or upgrade requirements of specific components.
  • Better Asset Management: By identifying and assessing individual components, the Component Approach helps organizations manage assets more effectively. It enables precise evaluation of value, useful life, and potential impairment for each component, aiding strategic asset planning and resource allocation.
  • Accurate Depreciation and Impairment Recognition: The Component Approach recognizes varying useful lives and depreciation rates for different components. This ensures accurate accounting measures that reflect the consumption of economic benefits and potential impairment risks.
  • Enhanced Comparability: The Component Approach allows for better comparability across entities and industries. Detailed component information facilitates benchmarking and industry analysis, supporting evaluation of asset performance. 


The Component Approach improves financial reporting and decision-making by providing accurate, transparent, and detailed asset information. It supports informed decision-making, strategic planning, and efficient asset management.


The Component Approach, as prescribed by IAS 16, significantly enhances financial reporting and decision-making. By recognizing and measuring individual components of assets, this approach brings transparency, accuracy, and granularity to financial statements. It allows for a precise evaluation of each component’s value, useful life, and potential impairments, providing stakeholders with comprehensive asset information. 

This detailed view enables better decision-making regarding maintenance, replacement, and resource allocation. Moreover, accurate depreciation and impairment recognition at the component level ensures reliable financial reporting. 

The Component Approach also promotes comparability across entities and industries, facilitating benchmarking and industry analysis. Ultimately, by adopting the Component Approach, organizations can improve asset management, optimize resource allocation, and enhance their overall financial performance.
