According to a letter released Monday by U.S. Soccer President Carlos Cordeiro, the federation paid out $34.1 million in salary and game bonuses to the women between 2010 and 2018 as opposed to $26.4 million paid to the men. The total does not include the value of benefits received only by the women, like health care.

The federation released the figures as it moves toward mediating a federal lawsuit in which players for the women’s team accused U.S. Soccer of “institutionalized gender discrimination” that includes inequitable compensation when compared to players on the men’s team.

Comparing compensation between the two teams is difficult because the pay structure is based on different collective bargaining agreements. For example, players for the women’s team have a base salary while the men are paid primarily based on matches and performance.
