It's unclear how the agreement will affect a special hearing of NBA owners planned for Tuesday in New York to consider the charge against Donald Sterling for damaging the league with his comments. A three-quarters vote of the 30 owners to support the charge would have resulted in the termination of both Sterlings' ownership of the franchise. The deal is expected to be presented to the league before Tuesday, according to the individual.
Silver has said his preference would be for the franchise to be sold rather than seized — and that means sold in its entirety, with neither Sterling retaining a stake. Though according to the deal's terms Ballmer will own 100 percent of the team, Shelly Sterling may continue to be involved under conditions worked out privately with Ballmer, the individual said.
Franchise sale prices have soared since the current collective bargaining agreement was ratified in 2011. The Milwaukee Bucks were just sold to New York investment firm executives Marc Lasry and Wesley Edens for about $550 million, an NBA record.
Last year, Vivek Ranadive's group acquired a 65 percent controlling interest in the Sacramento Kings at a total franchise valuation of more than $534 million.
This is not Ballmer's first foray into potential NBA ownership. Ballmer and investor Chris Hansen headed a group that agreed to a deal to buy the Kings from the Maloof family in January 2013 with the intention of moving the team to Seattle, where the SuperSonics played until 2008.
But Sacramento Mayor Kevin Johnson lobbied the NBA for time to put together a bid to keep the team in California, and though the Ballmer-Hansen group later increased its offer, owners voted to deny the bid for relocation and the Kings were sold to Ranadive.
The former Microsoft CEO helped Bill Gates transform the company from a startup with fewer than 40 employees and $12 million in annual revenue into the world's most valuable business. The pair met in 1973 while living down the hall from each other in a Harvard dorm.
During his tenure at Microsoft, Ballmer was known for his competitive drive and wild displays of emotion and hand-waving.
At his farewell address to Microsoft employees, he high-fived and hugged audience members, pumped his fists in the air, and even shed tears as the popular 1987 song "(I've Had) The Time of My Life" played on the sound system. In a video of the event widely viewed on YouTube, he screams: "You work for the greatest company in the world!"
