There are 127 active IOC members and all will vote except president Jacques Rogge and those from Canada, Austria and South Korea.

The members are grouped in the following areas:

Europe: 56
Americas: 21
Asia: 26
Africa: 17
Australia/Oceania: 6

On July 2, in Prague, Czech Republic, the three remaining Olympic bid cities for the 2010 Winter Olympic Games will make their final bid presentation to International Olympic Committee members.

Each city will have 45 minutes to make its bid presentation before the full IOC membership, followed by a 15-minute question period.

Vancouver will present first, followed by Salzburg and Pyeongchang.

Once the presentations and question periods are over, the voting will take place.

Though there are 127 active members in the IOC, only 119 will vote in the first round of balloting.

The IOC president, Jacques Rogge, as well as Canada and South Korea's three representatives and Austria's representative are not eligible to vote.

The vote is done by secret ballot and each eligible IOC member votes for one city.

If, after the first round, no city has a majority of the votes, the city with the fewest votes will be eliminated and another round of voting will begin. This process will continue until one city receives a majority.

If an IOC member was not eligible to vote because their country was on the ballot and their country gets eliminated, they become eligible to vote in any future rounds.

In case of a tie between two cities with the least amount of votes in a round when further rounds are required, a special ballot will be held to decide which city to eliminate. In case of a tie between two cities on the final ballot, the Chairperson of the Session will cast the deciding vote.
