Hansen has had a deal since January to buy a 65 percent controlling interest in the Kings from the Maloof family. He originally offered a total valuation of $525 million, then increased that offer to $550 million after a competing Sacramento group matched his deal. He hoped to move the team to Seattle and rename it the Sonics, who were relocated to Oklahoma City and renamed the Thunder in 2008.
The NBA's relocation committee voted 7-0 last week to recommend that the NBA Board of Governors which consists of all 30 owners reject the Seattle move. The board is expected to vote on the issue at its meeting in Dallas on Wednesday.
Hansen, in his Friday statement, said the Seattle group's arena proposal was more advanced than the one in Sacramento. He said the Seattle ownership group had bought all of the needed property, had 100 percent of the private financing "committed and in place" and added that the environmental review process was further along.
"While we appreciate that this is a very difficult decision for the league and owners, we hope it is understood that we really believe the time is now to bring the NBA back to Seattle, and that it is paramount that we do everything we can to put Seattle's best foot forward in this process," Hansen said.
Sacramento Mayor Kevin Johnson said the city "felt very confident" about keeping the Kings in California.
"The NBA leadership and owners have always said that their decision would not be dictated by a bidding war. This was always about whether Sacramento, a community that has supported the NBA for 28 years, can put together a plan and organization to ensure the franchise can rebuild and thrive," he said in a statement.
