Consistent with various industries facing different challenges, the most common deficiencies in the Banking Industry are in Segregation of Duties (14.3 percent versus 7.6 percent) and Account Reconciliation (13.6 percent versus 7.6 percent), while the most common problem in the Utilities Industry is in Complex Accounts (7.1 percent versus 3.8 percent). The banking industry has historically experienced breakdowns due to segregation of duties, as noted in the Framework for the Evaluation of Internal Control Systems by the Basle (a.k.a. Basel) Committee on Banking Supervision (1998): "Lack of segregation of duties in particular has played a major role in the significant losses that have occurred at banks." On the other hand, utility companies often engage in complicated transactions, such as hedging, which usually involve the interpretation and application of complex accounting standards. For example, El Paso Corporation, a natural gas pipeline company, disclosed a material weakness in applying complex accounting standards related to many of their hedge transactions.
