If the regulations note that candidates are banned from taking loans, code “YES”. If legislation includes an exhaustive list of allowed sources of income, and this does not include loans, code “YES”. By an “exhaustive list” is meant where it is stated something like “candidates are only allowed to receive income from the following sources” or (vaguer) “candidates may receive funding from the following sources”. If it says something like “allowed sources for candidates include...” it is not exhaustive. If regulations state that loans are permitted but with certain restrictions, for example from what types of institutions that loans may be obtained, or if there is a maximum amount that may be raised as loans, code “SOMETIMES”. If the regulations state that loans may be obtained by candidates, and no limitations are provided, code “NO”. If the issue of loans is not addressed in the regulations regarding income for candidates, code “NO”. If you have not found any information but you judge that there may likely be regulations you have not been able to access about this issue, code “ND”.
