These non-GAAP financial measures are frequently used by securities analysts, investors, and other interested parties in the evaluation of companies in Customers' industry. These non-GAAP financial measures exclude from corresponding GAAP measures the impact of certain elements that we do not believe are representative of our ongoing financial results, which we believe enhance an overall understanding of our performance and increases comparability of our period to period results. Investors should consider our performance and financial condition as reported under GAAP and all other relevant information when assessing our performance or financial condition. The non-GAAP measures presented are not necessarily comparable to non-GAAP measures that may be presented by other financial institutions. Although non-GAAP financial measures are frequently used in the evaluation of a company, they have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our results of operations or financial condition as reported under GAAP.
