Statements of commercial nature
If a PhD student intends to acknowledge support for their doctoral research from outside the university in writing, this may only be done following consultation with their supervisor and with the permission of the Doctorate Board. Statements of a commercial nature are not allowed in the thesis itself (source: procedural regulation no. 16 of the Vrije Universiteit Amsterdam Doctorate Regulations). PhD students who violate this rule may be required to reprint their thesis.
