The company believes that certain non-GAAP measures, when presented in conjunction with comparable GAAP (Generally Accepted Accounting Principles) measures, are useful because that information is an appropriate measure for evaluating the company's operating performance. Internally, the company uses this non-GAAP information as an indicator of business performance, and evaluates management's effectiveness with specific reference to these indicators. These measures should be considered in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.
