(1) In conjunction with the acquisition of SiriusDecisions, the Company realigned its management structure on January 1, 2019 into Research, Product, and SiriusDecisions from its prior structure of Research, Product, and Project Consulting. Goodwill was reassigned as of January 1, 2019 based on the relative fair values of the Research and Product reporting units.

(2) The goodwill related to the acquisition of SiriusDecisions was allocated to the SiriusDecisions segment, except for the portion of goodwill representing revenue synergies that are expected to benefit the Research segment.

(3) On January 1, 2020, the Company realigned its internal management and reporting as SiriusDecisions no longer operated under a separate management structure. As a result, the SiriusDecisions segment was eliminated (refer to Note 12 – Operating Segment and Enterprise Wide Reporting). Goodwill was reassigned on January 1, 2020 based on the relative fair values of the product lines transferred to the Research and Product reporting units.

(4) As described in the Company’s Form 8-K filed on April 2, 2020, Forrester’s Chief Product Officer resigned from the Company effective April 17, 2020. Subsequently, the Chief Product Officer position was eliminated and on May 1, 2020, the Company reorganized its operations to reflect three lines of business: Research, Consulting, and Events. As a result, the Product segment was eliminated (refer to Note 12 – Operating Segment and Enterprise Wide Reporting). Goodwill was reassigned based on the relative fair values of product lines transferred to the Research, Consulting, and Events reporting units. No goodwill was reassigned to the Events reporting unit.
