摘要:Several changes in the legislation governing accounting practices of construction sector companies boosted the internationalization of information on revenues of customer contracts in accounting. Brazil has stood out for early voluntary adoption of IFRS15 standard. Thus, the study aims to determine the relationship between the quality of accounting information and the early adoption of IFRS 15 by Brazilian construction companies listed on BM &FBovespa. The study is characterized as descriptive, conducted through document analysis and quantitative approach. The sample consists of 23 companies in the construction sector. Were analyzed quarterly data from 2013 to 2015. For the data analysis was made using multiple linear regression with panel data, on the basis of accounting information for quality measurement model of value relevance proposed by Ohlson (1995). The survey results suggest that early adoption of IFRS15 helps to reduce the bias of non-comparability and inconsistencies that could exist previously, due to the adoption of different criteria for accounting of revenues on construction contracts. In addition, organizations that voluntarily adopt the rule in an attempt to account for and properly recognize customer contracts revenue, have greater informational relevance and meet market expectations. Thus, it can be said that the early adoption of information on revenue from construction contracts have relevance to the capital market, impacting the stock price after the publication of financial reports.
