Reasons for Corporate Governance failure in Islamic Banks?

Inorder to avoid any corporate governance failure, one must be committed to maintaining high standards of corporate governance standards and business ethics in dealing with customers and other stakeholders.
Every companies, including Enron or World Com or Satyam (India) had similar reasons for failure....i.e.
lack of sound corporate governance standards....including mis-reporting, loopholes in the application of accounting standards and disclosure etc.
Hence, in general, issues like conflict of interest, family run business, manipulation of accounts by the management, lack of objectivity in external auditors work etc.
signifies poor corporate governance standards and can lead to the downfall of the organisation...guess the same applies with Islamic banks too...i.e.
if the tone at the top is not driving the correct behavior then the organisation might fall someday....

Generally speaking, the main reason is related to adoption of the best practices or lack of enforcement by the central banks or regulators.
