Non-GAAP Measures

This communication contains certain non-GAAP financial measures of Premier determined by methods other than in accordance with generally accepted accounting principles. We use non-GAAP financial measures to provide meaningful supplemental information regarding our performance. We believe these non-GAAP measures are beneficial in assessing our operating results and related trends, and when planning and forecasting future periods. These non-GAAP disclosures should be considered in addition to, and not as a substitute for or preferable to, financial results determined in accordance with GAAP. The non-GAAP financial measures we use may differ from the non-GAAP financial measures other financial institutions use to measure their results of operations.
