In all years presented, the fair values of non-controlling interests were determined using an income approach with reference to a discounted cash flow model using the same assumptions implied in determining the purchase consideration. The purchase price allocations of acquisitions resulted in the recognition of goodwill. The primary factors contributing to goodwill are assembled workforces, synergies with existing operations and future growth prospects. For acquisitions completed during the year ended December 31, 2018, goodwill in the amount of $379,486 is deductible for income tax purposes ( 2017 - $17,531 ). During the year ended December 31, 2018, the Company sold the residential property management portion of the Finland business acquired earlier in the year. The disposed business had net assets of $17,713 primarily comprised of intangible assets and goodwill allocated from the acquisition of Finland and the sale resulted in a net gain of $98. The Company typically structures its business acquisitions to include contingent consideration. Certain vendors, at the time of acquisition, are entitled to receive a contingent consideration payment if the acquired businesses achieve specified earnings levels during the one - to five -year periods following the dates of acquisition. The ultimate amount of payment is determined based on a formula, the key inputs to which are (i) a contractually agreed maximum payment; (ii) a contractually specified earnings level and (iii) the actual earnings for the contingency period. If the acquired business does not achieve the specified earnings level, the maximum payment is reduced for any shortfall, potentially to nil. Unless it contains an element of compensation, contingent consideration is recorded at fair value each reporting period. The fair value recorded on the consolidated balance sheet as at December 31, 2018 was $93,865 (see note 18 ). Contingent consideration with a compensatory element is revalued at each reporting period and recognized on a straight-line basis over the term of the contingent consideration arrangement. The liability recorded on the balance sheet for the compensatory element of contingent consideration arrangements as at December 31, 2018 was $15,161. The estimated range of outcomes (undiscounted) for these contingent consideration arrangements is determined based on the formula price and the likelihood of achieving specified earnings levels over the contingency period, and ranges from $175,870 to a maximum of $206,906. These contingencies will expire during the period extending to March 2023. During the year ended December 31, 2018, $19,946 was paid with reference to such contingent consideration ( 2017 - $11,187 ). The consideration for the acquisitions during the year ended December 31, 2018 was financed from borrowings on the Revolving Credit Facility and cash on hand. The amounts of revenues and earnings contributed from the dates of acquisition and included in the Companys consolidated results for the year ended December 31, 2018, and the supplemental pro forma revenues and earnings of the combined entity had the acquisition dates been January 1, 2017, are as follows: Revenues Net earnings Actual from acquired entities for 2018 $ 196,480 $ 10,879 Supplemental pro forma for 2018 (unaudited) 2,934,211 139,297 Supplemental pro forma for 2017 (unaudited) 2,738,081 118,078 Of the $196,480 of actual revenue from acquired entities in 2018, $61,465 and $45,364 were from Harrison Street and Finland, respectively, with the remaining $89,651 from other acquisitions.
