The entire disclosure for real estate owned (as defined). Generally, the largest component of real estate owned by lenders is assets taken in settlement of troubled loans through surrender or foreclosure. Real estate investments, real estate loans that qualify as investments in real estate, and premises that are no longer used in operations may also be included in real estate owned.
