Subsequent Events	12. Subsequent Events On January 5, 2015, the Company announced that James P. Scholhamer would become the Company’s Chief Executive Officer, effective January 19, 2015, succeeding Clarence L. Granger, who retired as the Company’s Chief Executive Officer on such date. Mr Granger will remain as non-executive Chairman of the Board of Directors. Mr. Scholhamer also joined the Company’s Board of Directors, effective as of his first day of employment with the Company. In February 2015, the Company completed the acquisition of substantially all of the assets and certain liabilities of Marchi, a designer and manufacturer of specialty thermocouples, heaters and temperature controllers, for approximately $30.0 million in cash and 1,437,500 shares of newly issued common stock for a total purchase price of approximately $44.0 million. In addition, the Company incurred approximately $0.5 million of costs related to the acquisition. The Company’s primary reason for this acquisition is to expand its capabilities with its existing customers and bring the Company closer to the customer in the design stage of new products and next generation equipment. The Company financed the cash portion of the acquisition by borrowing a total of $29.7 million under the new Credit Agreement. Following the acquisition of Marchi, the Company’s cash totaled approximately $77.4 million and total debt was approximately $76.2 million. See further discussion of the new borrowing arrangements in Note 5 to the Notes to Consolidated Financial Statements. Due to the limited time since the acquisition date and limitations on access to Marchi’s information prior to the acquisition date, the initial accounting for the business combination is incomplete at this time. As a result, the Company is unable to provide amounts recognized as of the acquisition date for major classes of assets and liabilities acquired and resulting from the transaction, including the information required for indemnification assets, contingencies, non-controlling interests and goodwill. Also, because the initial accounting for the transaction is incomplete, the Company is unable to provide the supplemental pro forma revenue and earnings of the combined entity. The Company will include this information in its Quarterly Report on Form 10-Q for the three months ended March 27, 2015.
