A Company-wide annual impairment test is conducted as of October 1 of each year and updated on a more frequent basis when events or circumstances indicate that impairment could have taken place. Results of the testing for 2013 concluded that no impairment was present in any of the operating segments. For 2012, no impairment was present, except for TCBO included in the Other segment. A comparison of fair value to carrying value determined that the entire remaining $1 million of TCBO’s goodwill should be impaired.
