A brand new 12-team Fed Cup Finals will take place on clay in Budapest in Hungary, in April of next year.
As BBC Sport reported in March, 20 teams will have the chance to be crowned world champions each year, with eight qualifying ties taking place in February.
The winners of those ties will join this year's finalists Australia and France, hosts Hungary and one wildcard nation in the inaugural Finals.
There is an $18m (£14.2m) prize fund.
Of that, $12m (£9.5m) will go to the players, and the other $6m (£4.75m) to their national associations.
