Member countries are allocated votes at the time of membership and subsequently for additional subscriptions to capital. Votes are allocated differently in each organization.

Each member receives votes consisting of share votes (one vote for each share of MIGA's capital stock held by the member) plus parity votes, calculated so that the aggregate number of votes of category 1 and category 2 members is the same. Members choose which category they want to join at the time of membership. Category 1 members were originally defined as developed countries and category 2 members as developing countries.
