6.	Contingent Consideration

Acquisitions may include contingent consideration payments based on future financial measures of an acquired company. Under ASC 805, Business Combinations, contingent consideration is required to be recognized at fair value as of the acquisition date. We estimate the fair value of these liabilities based on financial projections of the acquired companies and estimated probabilities of achievement. At each reporting date, the contingent consideration obligation is revalued to estimated fair value and changes in fair value subsequent to the acquisition are reflected in income or expense in the consolidated statements of operations and could cause a material impact to our operating results. Changes in the fair value of contingent consideration obligations may result from changes in discount periods and rates, changes in the timing and amount of revenue and/or earnings estimates and changes in probability assumptions with respect to the likelihood of achieving the various earn-out criteria.

In connection with the acquisition of DP Engineering on February 15, 2019, the Company recognized the estimated fair value of contingent consideration for $1.2 million. During the six months ended June 30, 2019, as a result of the triggering event described in Note 8, an impairment test was conducted on DP Engineering's goodwill and definite-lived intangible assets and the Company determined the $1.2 million of contingent consideration recognized upon acquisition of DP Engineering has reduced to zero since the related earn-out payment is no longer expected to be paid. We have recorded this reduction as an offset to selling, general and administrative expenses in unaudited consolidated statements of operations. There was no contingent liability as of June 30, 2019.
