It is mandatory for the network as a whole to provide at least the number of person-months stated in the contract. In practice, this means that if any team has difficulty filling its person-months, it must arrange with another team to make up the difference, possibly transferring the necessary funding.

It is mandatory for each team to preserve full documentation about every young researcher it hires, including proof of eligibility and financial records. These must be communicated to the network coordinator each year for the financial report.

In order to prove their presence, the EC requires post-docs and pre-docs to fill out daily time-sheets with their hours of presence, which must be signed by the team leader.

Each postdoc hired by the network is required to fill out a confidential questionnaire provided by the EC, containing an assessment of their experience, before leaving. These questionnaires are mandatory and will be reported to the EC.

Each postdoc hired by the network has the right to a visit to his/her home mathematical community every nine months, with travel financed by the network.

Within reason, it is legitimate to redistribute some person-months between pre-docs and post-docs at a rate of 2 postdoc-months=3 pre-doc months, and also the year-by-year distribution.

Each team is responsible for verifying the eligibility of a postdoc they wish to hire. If it turns out later that a postdoc who was hired was not eligible, the team must reimburse the EC.

When hiring a postdoc, a team is encouraged to check that the candidate has employment for the remaining part of the year, possibly directing him/her to open positions at other teams.
