The goodwill acquired in 2018 is related to the Bridgemedica acquisition as described in Note 3 and is derived from the value of the business acquired. We are in the process of analyzing the opening balance sheet and purchase price allocation. The preliminary fair value of the business acquired was based on management business plans and future performance estimates which are subject to a high degree of management judgment and complexity. Actual results may differ from these projections and the differences may be material, leading to measurement period adjustments of this goodwill.

In the first quarter of 2018, as a result of the changes in our organizational and management structure, goodwill was reassigned to operating segments using a relative fair value allocation. For further information on the organizational changes, see Note 1.
