(“Aeroworks”). Aeroworks, which is headquartered in The Netherlands and maintains significant production facilities in Thailand and Laos, is a manufacturer of both composite and metal parts used primarily in aircraft interior applications, including seating, galleys, lavatories, doors, and overhead bins. The remaining 20% interest continues to be owned by a certain member of Aeroworks' management team (see Note 3, Selected Financial Statement Information, for additional information). The total consideration includes an accrual representing the fair value of contingent consideration that the Company may be obligated to pay should Aeroworks meet certain earnings objectives during each of the first four years following the acquisition. See Note 7, Fair Value Measurements, for additional information regarding the Company’s contingent consideration obligation. In January 2015, the Company, through its HEICO Flight Support Corp. subsidiary, acquired 80.1% of the equity of Harter Aerospace, LLC ("Harter").

In May 2015, the Company, through its HEICO Flight Support Corp. subsidiary, acquired all of the stock of Thermal Energy Products, Inc. (“TEP”). TEP engineers, designs and manufactures removable/reusable insulation systems for industrial, commercial, aerospace and defense applications. The purchase prices of the fiscal 2015 acquisitions were paid in cash principally using proceeds from the Company’s revolving credit facility and the total consideration for the acquisitions is not material or significant to the Company's condensed consolidated financial statements. The allocation of the total consideration to the tangible and identifiable intangible assets acquired and liabilities and noncontrolling interests assumed for the Aeroworks and Harter acquisitions is preliminary until the Company obtains final information regarding their fair values.

The amount of net sales and earnings of Aeroworks and Harter included in the Condensed Consolidated Statements of Operations is not material. Had the Aeroworks and Harter acquisitions been consummated as of November 1, 2013, net sales, net income from consolidated operations, net income attributable to HEICO, and basic and diluted net income per share attributable to HEICO shareholders on a pro forma basis for the six and three months ended April 30, 2015 and April 30, 2014 would not have been materially different than the reported amounts.
