Goodwill And Intangible Assets Disclosure [Abstract]

7. Goodwill and Intangible Assets

Goodwill

Goodwill is recorded when the consideration for a business combination exceeds the fair value of net tangible and identifiable intangible assets acquired. The Company tests its goodwill balances annually for impairment as of the beginning of the second quarter or more frequently if indicators are present or changes in circumstances suggest that impairment may exist. The Company performed its last annual goodwill impairment test at the beginning of the second quarter of 2016 and noted no impairment of goodwill. Implied fair value of all reporting units exceeded their carrying values by at least 20%.

The following table summarizes changes in goodwill during the three months ended March 31, 2017 (in thousands):
