|Business Combinations [Abstract]
On December 31, 2015, we acquired Ultra Seating Company ("Ultra Seating") for approximately $3.6 million, which represents cash consideration of $3.8 million adjusted for the settlement of pre-existing liabilities and a final working capital adjustment. Ultra Seating provides specialized seating for commercial trucks and buses. Ultra Seating is included in our Supply Chain Management Group.
We have completed our purchase price allocation and recognized fair values of assets acquired (including intangible assets), liabilities assumed and the amortization period for the intangible assets. We recorded approximately $2.0 million of goodwill and approximately $1.5 million of intangible assets, primarily related to customer relationships and a trade name. During 2016, we recorded immaterial purchase accounting adjustments based on changes to management’s estimates and assumptions in regards to acquired intangible assets and assumed liabilities.
The pro forma effects, assuming our acquisition of Ultra Seating had occurred as of January 1, 2015, were not material to our total revenues, net income or earnings per share for the year ended December 31, 2015.
On January 28, 2015, we acquired four related businesses that perform maintenance, repair and overhaul ("MRO") services and parts supply for general aviation jet aircraft engines and engine accessories. The acquired businesses include Air Parts & Supply Co., Kansas Aviation of Independence, L.L.C., Prime Turbines LLC (including U.S. and German-based operations), and CT Aerospace LLC (collectively, "the Aviation Acquisition"). These four businesses are operating as a combined group managed by our subsidiary VSE Aviation, Inc.
The initial purchase consideration paid at closing for the Aviation Acquisition was approximately $189 million, which included an estimated net working capital adjustment of approximately $5 million. Additional cash consideration of $2.4 million was paid to the sellers during the third quarter of 2015 based on the final working capital adjustment.
We were required under a post-closing-earn-out obligation contained in the Aviation Acquisition agreement to make additional purchase price payments of up to $40 million if the acquired businesses satisfied certain financial targets during the first two post-closing years. Consideration of $5 million was paid to the sellers in September 2015 because certain of the acquired businesses surpassed agreed upon financial targets during a 12- consecutive month period in 2014 and 2015. In July 2016, VSE and the sellers of the four aviation businesses agreed upon an early termination of the earn-out obligation and a final payment amount. VSE paid the sellers approximately $8.0 million as an earn-out payment in May 2016 and the final earn-out payment of approximately $10.5 million in July 2016.
We incurred approximately $528 thousand of acquisition-related expenses during the year ended December 31, 2015 which are included in selling, general and administrative expenses.
