Managing Critical Spreadsheets in a Compliant Environment
  The use of uncontrolled financial spreadsheets can expose organizations to unacceptable business and compliance risks, including errors in the financial reporting process, spreadsheet misuse and fraud, or even significant operational errors. These risks have been well documented and thoroughly researched. With the advent of regulatory mandates such as SOX 404 and FDICIA in the U.S., and MiFID, Basel II and Combined Code in the UK and Europe, leading tax and audit firms are now recommending that organizations automate their internal controls over critical spreadsheets and other end-user computing applications, including Microsoft Access databases. At a minimum, auditors mandate version control, change control and access control for operational spreadsheets, with more advanced controls for critical financial spreadsheets. This paper summarises the key issues regarding the establishment and maintenance of control of Business Critical spreadsheets.
