The goodwill adjustments during the first nine months of 2016 are the result of updates to preliminary fair value estimates related to the 2015 acquisitions of Florida Bank Group, Old Florida, and Georgia Commerce, during the respective measurement periods. See Note 3 for further information on these acquisitions.

The Company performed the required annual goodwill impairment test as of October 1, 2015. The Company’s annual impairment test did not indicate impairment in any of the Company’s reporting units as of the testing date. Following the testing date, management evaluated the events and changes that could indicate that goodwill might be impaired and concluded that subsequent interim tests were not necessary. The Company is currently in the process of performing its annual impairment test as of October 1, 2016.
