When the chief audit executive (CAE) reports to the chief financial officer (CFO), it can create a potential conflict of interest and impair the independence of the internal audit activity. This reporting structure may lead to limitations in the scope of engagements, particularly when auditing areas under the CFO's purview.
Independence and objectivity are critical for the effectiveness of internal auditing, and reporting to the CFO can undermine these principles, restricting the ability to audit financial and other related areas without bias or undue influence.

The chief audit executive must confirm to the board, at least annually, the organizational independence of the internal audit activity."

Intangible assets are indeed categorized as having either a limited life or an indefinite life. Those with a limited life are amortized over their useful life, whereas those with indefinite lives, such as some types of intellectual property, are not amortized but must be tested annually for impairment. This categorization helps in the appropriate financial treatment of intangible assets under accounting standards.
