Acquisition

On May 2, 2012, we acquired certain assets and technology from IMCO for a total estimated consideration of $3.7 million. During 2012, we increased goodwill by $2.1 million and intangible assets by $1.4 million for this acquisition. The intangible assets are being amortized over a four year period. During the fourth quarter of 2012, we reassessed the projected royalty payments to IMCO and reduced the expected future liabilities by $0.2 million based on recent data. During the fourth quarter of 2013, we reassessed the projected royalty payments to IMCO and further reduced the expected future liabilities by $0.2 million. During the year ended December 31, 2013, we paid $18,000 in royalties to IMCO.
