The paper analyses the first-time adoption of IFRS 15 and reports on the appropriateness, rigour and decision usefulness of revenue disclosure practices in South Africa. The decision usefulness is assessed by reviewing the nature, amount, timing and uncertainty of revenue recognition information. A disclosure checklist was used for the content analysis and interpretation of a selection of South African listed companies. In most instances, revenue disclosures appeared to be orderly, concise, coherent and appropriately cross-referenced, indicating that generally companies were able to deal appropriately with entity-specific information regarding the nature, amount and timing of revenue recognition. Specifically, the disaggregation of revenue, the accounting policies and the transitional requirements were applied appropriately. However, two main concerns were identified, which compromise the decision usefulness of revenue recognition. Firstly, misalignment between the IFRS 15 information in the annual financial statements and the interim financial statements was identified in the first year of the application of IFRS 15. The finding indicates that some entities need to start their process of adopting a new financial reporting standard earlier. Secondly, specific assumptions and judgments regarding revenue recognition, determining the transaction price and measuring obligations for returns, refunds and other similar obligations were not always disclosed. Insufficient disclosure specifically regarding the uncertainty of revenue recognition could compromise the decision usefulness of revenue information. The findings of this paper contribute to the understanding of the first-time adoption implications of new accounting standards, such as IFRS 15.

该文件分析了首次采用 IFRS 15 的情况，并报告了南非收入披露做法的适当性、严谨性和决策有用性。决策的有用性是通过审查收入确认信息的性质、金额、时间和不确定性来评估的。披露清单用于对选定的南非上市公司进行内容分析和解释。在大多数情况下，收入披露似乎是有序、简明、连贯和适当的交叉引用，表明一般公司能够适当地处理关于收入确认的性质、金额和时间的实体特定信息。具体而言，收入的分解、会计政策和过渡要求得到了适当的应用。然而，确定了两个主要问题，它们损害了收入确认的决策效用。首先，在应用 IFRS 15 的第一年发现了 IFRS 15 年度财务报表信息与中期财务报表信息之间的不一致。 调查结果表明，一些主体需要更早开始采用新财务报告准则的过程. 其次，关于收入确认、确定交易价格和计量退货、退款和其他类似义务的具体假设和判断并不总是披露。未充分披露特别是关于收入确认的不确定性可能会损害收入信息的决策效用。
