Discontinued Operations

The Granville-Phillips business unit developed, manufactured, sold and serviced vacuum measurement and gas analysis instrumentation to semiconductor and non-semiconductor customers. In March 2014, the Company entered into an agreement to sell this business for $87.0 million in cash. The sale was completed on May 30, 2014. The Company’s historical financial statements have been revised to present the operating results of the Granville-Phillips business as a discontinued operation. The presentation of the Granville-Phillips business as a discontinued operation had no impact on previously reported net income (loss) or stockholders' equity.
