Where businesses are underperforming, in distress or in crisis, either equity or debt providers often ask for an Independent Business Review (or IBR) to be carried out.
The benefit from an experienced third party reviewing the operations is to obtain an independent and objective assessment of the current performance and potential rectifying options.
Also, management at group level might request such review from a strategic point of view to better assess reasons for an actual crisis of a subsidiary and to identify measures in response.
