The standard d'Hondt formula is applied to the vote (except for the twelfth constituency in which national minority representatives are elected), with a five-percent election threshold in each constituency. Since 2015, the parliamentary elections have an element of preferential voting by letting voters choose not only for a list of candidates, but also a single member of the same list. If the percentage of votes for a candidate exceeds 10%, they are elected as if it was an open list system. The list ranking is maintained for those candidates that do not meet this quota.
