The users recognize timeliness as an important characteristic of usefulness of accounting information. The timing of an annual report announcement is a disclosure decision that managers must make. In this research, we investigate relationship between a set of Board Characteristics (such as Board Size, Ownership Percent, Board Independence and Duality of Chief) and timing of annual financial reporting. We have used the financial data of 128 firms listed at Tehran Stock Exchange (TSE), that have analyzed for during 2005 to 2011 by using of the Panel Data System and Ordinary Least Square Regressions (OLS) Model. The results of research show that among Board Characteristics, Ownership Percent of Board and Board Independence are positively associated with the annual financial reports earlier. Also, board size and duality of chief are not associated with the annual financial reports timing. Tests on panel data (Chow and Hausman) represents the restricted pattern used to estimate the regression model.
