After the filtering described above, a manual review of the companies was performed.
This review aimed at rejecting from the final dataset any companies undertaking more than baseline wholesale marketing and distribution activities based on scoping criteria outlined in Section 2.
Initially, keyword searches were used to make rejections of companies, and then manually reviewed the companies in the dataset using only the descriptive information on businesses activities provided in the database.
This review comprised -
Rejection of companies with the following terms in their business overview:
Rejection of all companies that do not describe wholesale distribution as their main activity.
Rejection of companies which describe any development, research or manufacturing activity, or more than minority or ancillary levels of additional activities such as retail, repairs and maintenance, and other services.
