This study analyzes the severity of Internal Control over Financial Reporting deficiencies (Deficiencies, Significant Deficiencies and Material Weaknesses) in a sample of Italian listed companies, in the period 2007- 2012. Using proprietary da- ta the severity of the deficiencies is tested for account-specific, entity level and in- formation technology controls and for industries (manufacturing and services vs finance industries). The results on ICD severity is compared with one of the most frequent ICD (Acc_Period End/Accounting Policies): for account-specific, ICD in revenues, purchase, fixed assets and intangible, loans and insurance are more se- vere while ICD in Inventory are less severe. Differences in ICD severity have been found in the characteristic account: ICD in loan and insurance for finance industry and ICD in revenue, purchase for manufacturing and service industry are more se- vere. Finally, we found that ICD in entity level and information technology con- trols are less severe than account specific ICD in all industries. However, the re- sults on entity level and information technology deficiencies could also mean that the importance of these types of control are under-evaluated by the manufacturing and service companies.
