USE OF NON-GAAP FINANCIAL INFORMATION
The company presented the following measures considered as non-GAAP by the U.S. Securities and Exchange Commission:  gross profit margin, net income and diluted earnings per share excluding the effects of NexPlanar acquisition-related costs, amortization expense and impairment of an intangible asset.  The non-GAAP financial information provided in this press release is a supplement to, and not a substitute for, the company’s financial results presented in accordance with U.S. GAAP.  These non-GAAP financial measures are provided to enhance the investor's understanding about the company's ongoing operations.  Specifically, the company believes the NexPlanar acquisition-related costs, amortization expense and impairment charge are not indicative of its core operating results, and thus presents its gross profit margin, net income and diluted earnings per share excluding these costs.  The presentation of non-GAAP financial information is not meant to be considered in isolation or as a substitute for results prepared and presented in accordance with U.S. GAAP.  A reconciliation table of GAAP to non-GAAP financial measures, including gross profit margin, net income and diluted earnings per share, is contained in this press release.
