1) Currently, SOX requires mandatory rotation of the lead engagement partner every 5 years. After 5 years, the partner rotates off the engagement and a new partner from the same firm becomes the lead engagement partner.

For example, is there a length of time where an auditing firm has audited the financials of the same company for too many years?

2) Why do auditors need to be knowledgeable about "information technology"?
