I'll attempt to answer that one.
The concept of the minimal fee may mean that you would have to put a less experienced person to prepare the response, whereas a reasonable fee is the fee that reflects the resources the company has to put internally to develop that response.
The example we would give is for insurance files. There is oftentimes a lot of documentation. Some of it is work product of the insurer. Other aspects of the insurance claims file is the personal information. To have a minimal cost, you'd put a very junior person without the experience to do that analysis, and they would get it all mixed up. Therefore, you have to have the right level of expertise internally assigned to that task. That right level of expertise will have perhaps a higher cost than the minimal cost that the insurer could do, but they have to do it right. Therefore, the reasonable cost is the cost of getting the right expertise to do the job to assemble the information to respond to the request.
