The 50-seat majority bonus system was used for the first time in the May 2012 election; it reserves 50 parliamentary seats for the party emerges as the largest by total votes cast on a national level. The remaining 250 seats are divided proportionally in parliamentary constituencies according to each party's total "valid" vote percentage; this is slightly higher than the raw percentage reported, as there is always a small number of invalidated or "blank" votes (usually less than 1%), as well as the percentage of smaller parties that fail to surpass the 3% threshold, all of which are disregarded for the purpose of seat allotment. The previous law (used in the 2009 legislative elections) was less favorable for the plurality party, as only 40 additional seats were reserved for them.
