The third column of regression results includes all of the variables, and thus multiple measures of the same characteristic (such as firm size). Not surprisingly, the size measures become insignificant (note the extremely high correlation between these variables in Table 5). In addition, CFO/A is not significant in the presence of ROA. The remaining variables have coefficients that are similar to the first two columns. Overall, of the firm aspects we examine, complexity, size, profitability, and auditor appear to be associated with whether firms disclose material weaknesses.
