Maguire Properties' founder and former chief executive proposed to take over three of the company's Southern California properties. In a letter, Robert Maguire III proposed to assume the loans on KPMG Tower, US Bank Tower and Plaza Las Fuentes. Maguire Properties CEO Nelson Rising, who succeeded Robert Maguire in 2008, said the Los Angeles company wouldn't sell the KPMG and US Bank towers but would be open to selling Plaza Las Fuentes. Rising said he would bring up the former CEO's proposal at a Tuesday board meeting.
