Key audit matter (continued)

We have fulfilled the responsibilities described in the Auditor's Responsibilities for the Audit of the Consolidated Financial Statements paragraph of our report, including in relation to the key audit matter communicated below. Accordingly, our audit included the performance of procedures designed to respond to our assessment of the risks of material misstatement of the accompanying consolidated financial statements. The results of our audit procedures, including the procedures performed to address the key audit matter below, provide the basis for our opinion on the accompanying consolidated financial statements.

Evaluation of property and equipment estimated useful lives

Description of the key audit matter:

As of December 31, 2022, the balance of consolidated property and equipment of the Group was Rp173,329 billion. As discussed in Notes 2ac and 11 to the accompanying consolidated financial statements, the Group reviews the estimated useful lives of its property and equipment at least annually and such estimates are updated if expectations differ from previous estimates due to changes in expectation of physical wear and tear, technical or commercial obsolescence, and legal or other limitations on the continuing use of the property and equipment.

Auditing the Group's estimated useful lives of property and equipment is complex and requires significant judgment because the determination of the estimated useful lives considers a number of factors, including strategic business plans, expected future technological developments, and market behavior.

Audit response:

We obtained an understanding and evaluated the design and tested the operating effectiveness, of internal controls over the Group's process of estimating the useful lives of its property and equipment. For example, we tested management's review control on checking the completeness and accuracy of the assets classification data and assessing the appropriateness of the judgments regarding the most relevant data to be considered in determining useful lives.

To test whether the estimated useful lives of property and equipment used by management was reasonable, our audit procedures included, among others, obtaining an understanding of management's strategy related to assets replacement and assessed the reasonableness of such assumptions by considering external sources, such as telecommunication technology growth, changes in market demand, and current economic and regulatory trends. We assessed whether there were any potential sources of contrary information by performing benchmarking analysis on the estimated useful lives of property and equipment against other public companies within the telecommunication industry.
