The ATP and Tennis Australia have confirmed they will stage a new ATP Cup team event as a curtain-raiser to the 2020 men's season.
It comes months after the International Tennis Federation (ITF) voted on a revamped and rival Davis Cup tournament from 2019, taking place in November.
In May, ATP executive chairman Chris Kermode said staging both tournaments within six weeks would be "insane".
The ATP Cup will have £11.35m in prize money on offer.
It will feature 24 nations in six groups of four and ranking points will be available for players.
