Every year WHO issues an annual questionnaire that identifies potential contributors. It is distributed to existing contributors, to all companies and institutions that conduct research and development in the field of influenza, and to all recipients of PIP biological material recorded in the Influenza Virus Traceability Mechanism (IVTM) database. Amounts to be paid by individual manufacturers are based on principles of transparency and equity, and take into account the manufacturers' nature and capacities. 

PC Preparedness funds are used to strengthen capacities globally, regionally and at country level. Details on financial and technical implementation information can be found in PIP Framework progress reports as well as on WHO’s Programme Budget portal.

A Partnership Contribution Independent Technical Expert Mechanism (PCITEM) meets each biennium to review the projects submitted for PC funds use.
