The ratings agency said there were $3.7 billion of newly delinquent loans in December, including Bank of America Plaza in Atlanta, while $3.5 billion were resolved or worked out. The $1.4 billion of new CMBS deals was more than offset by $5.5 billion of seasoned loan dispositions and payoffs, pushing the CMBS universe to $582.8 billion, analysts said. The $363 million loan that went into arrears in Atlanta is the seventh largest delinquent loan overall, according to Moody's. The delinquent rate in the hotel sector fell to 12.96% from 13.54% a month earlier, while multifamily declined to 14.44% from 14.88%, which remains the highest rate among the core asset classes, Moody's said. Retail delinquencies rose to 7.22% from 6.97% in November; industrial climbed to 12.09% from 11.5%; and office increased to 8.65% from 8.39%. Moody's specially serviced loan tracker fell to 11.97% in December from 12.1% the prior month. Write to Jason Philyaw. Follow him in Twitter: @jrphilyaw.
