The Goodwill written-off during fiscal 2017 was a result of our sale of our Regulatory Filing products to Fed Reporter on May 1, 2017. Goodwill allocated to the carrying amount of the net assets sold (mainly computer software) was calculated based on the relative fair values of the business disposed and the portion of the reporting unit that was retained.

The goodwill acquired during fiscal 2016 of $6,099 was a result of our purchase of Bayside Business Solutions, Inc. The goodwill arising from this acquisition consists largely of the growth potential, synergies and economies of scale expected from combining the operations of the Company with those of Bayside Business Solutions, together with the value of Bayside Business Solutions’ assembled workforce. Goodwill from this acquisition has been allocated to our Bank segment.

During fiscal 2016 the Company sold its Alogent business (Alogent) to Antelope Acquisition Co., an affiliate of Battery Ventures. Alogent was included in our Bank segment. Goodwill allocated to the carrying amount of the net assets sold was calculated based on the relative fair values of the business disposed and the portion of the reporting unit that was retained.
