Group A of the League of Legends tournament saw a three-way-tie between SK Gaming, eHome and iG. According to the rules at the Intel Extreme Masters, SK and eHome advanced.
The reason to this was explained by admin David Shawn Kugelmann:
In case of a tie between two or more teams in the groupstage the time coefficient will be used to determine which team advances. The time coefficient is determined by adding the duration of all losses and subtracting the duration of all wins of all tied teams among each other. This rewards fast wins and long losses.
The time coefficient of iG was exactly 1 minute and 53 seconds worse than eHome's. That's why they are out of the tournament.
