To examine the association between the degree of corporate disclosure and transparency and earnings attributes of losted firms in The Stock Exchange of Thailand. The sample of this study consists of Thai listed firm in SET100 index during year 2005-2008. The disclosure and transparency level is measured using Standard and Poor's transparency and disclosure scoring methodology (S&P:T&D). Earnings attributes are defined in terms of both accounting-based and market-based earnings attributes. The results show that accruals quality and smootness are negatively associated with total scores of disclosure and transparency. This indicates that investor confidence in financial statements. In addition, the study provides signicficant results of total scores indicating that the total scores may be driven by different levels of disclosures in ownership structure and investor rights and in board and management structure and process. On the other hand, the financial information disclosure is not associated with earnings attributes because the negative association between transparency and disclosure scores and earnings attributes of this study is consistent with the substitute relationship indicating that firms with poor earnings attributes usually issure more expansive disclosure.
