In January 2015, we acquired 100% of the voting equity interest of four businesses (the "Acquisition") that specialize in maintenance, repair and overhaul ("MRO") services and parts supply for corporate and regional jet aircraft engines and engine accessories. The businesses acquired include Air Parts & Supply Co., Kansas Aviation of Independence, L.L.C., Prime Turbines LLC, and CT Aerospace LLC.  These four businesses will operate as a combined group under our newly formed wholly owned subsidiary VSE Aviation, Inc. to expand our sustainment services into the aviation supply chain market. We have retained certain key members of the management group and the operating businesses.

The aggregate cash purchase price for the Acquisition was approximately $189 million (subject to working capital and inventory and equipment adjustments). We may also be required to make earn-out payments of up to $45 million if the Acquisition meets certain financial targets during the first two years after the closing of the Acquisition.

We expect to account for the transaction as a business combination and have not completed the purchase accounting for the Acquisition. We plan to file the required historical financial statements of the Acquisition and the required pro forma financial statements of the combined results of the Company and the Acquisition in a Form 8-K/A to amend the Current Report on Form 8-K filed on January 30, 2015 by April 13, 2015. Preliminary estimates of valuations are as follows (in thousands):
