In my perspective, and in the context of a public listed company where acquisitions reaching certain thresholds (mandating shareholder’s approval), I will go for a Fullscale DD (on the basis that the costs are say less than 5% of the purchase consideration). This will enable the board to “outsource the risk” to these external consultants whereas ensuring that costs are not prohibitive. In the event that the costs are more than 5%, I would consider going for a limited DD, subject to discussion with the external consultants.
