Abstract The legislation known as Sarbanes Oxley (SOX) requires firms to assess their internal controls over financial reporting and to report material weaknesses, as defined by the Public Accounting Oversight Board. Based upon early evidence, we find that firms with material weaknesses are, on average, both smaller and worse performers than their matched industry counterparts. We also find that firms with material weaknesses, on average, have higher betas, suggesting a higher discount by the market for these firms. From a macro-economic view, the total market value of firms with reported material weaknesses is only 1.28% of the market value of the S&P 500 firms. Finally, although we document negative stock returns on the date of the announcement of the material weakness, over a narrow interval, the returns are insignificant.
Identifying small firms that collectively constitute a minor portion of the economy at a very high cost to all public firms seems out of balance. Whether SOX will yield benefits to corporations through better operations, reduced cost of capital, or other means remains to be seen. Moreover, if these benefits materialize, whether they should, in effect, be legislated is a matter of debate. Although some maintain that SOX will reduce earnings management, firms continue to manage earnings through pro forma earnings. Furthermore, although the SEC’s Reg G, also enacted as part of SOX legislation, makes the “managed disclosure system” through pro forma earnings more transparent, it fails

SOX is an attempt to legislate better disclosure and internal control.
