The IIA navigator will be constantly adapted following the review and comments of UN Member States. It is mainly based on information provided by governments on a voluntary basis. A contract is included in a country`s IIA census as soon as it is formally concluded; Contracts whose negotiations have been concluded but not signed are not accounted for. A contract is excluded from the IIA`s census as soon as its termination takes effect, as soon as it continues to have a legal effect on certain investments during its survival period (“sunset”). In case of renewal of a contract, only one of the contracts between the same parties is counted.
