Non-GAAP Financial MeasuresTo supplement MYR's financial statements presented in accordance with generally accepted accounting principles in the United States (GAAP), MYR uses certain non-GAAP measures. Reconciliation to the nearest GAAP measures of all non-GAAP measures included in this press release can be found at the end of this release. MYR's definitions of these non-GAAP measures may differ from similarly titled measures used by others. These non-GAAP measures should be considered supplemental to, and not a substitute for, financial information prepared in accordance with GAAP. MYR believes that these non-GAAP measures are useful because they (i) provide both management and investors meaningful supplemental information regarding financial performance by excluding certain expenses and benefits that may not be indicative of recurring core business operating results, (ii) permit investors to view MYR's performance using the same tools that management uses to evaluate MYR's past performance, reportable business segments and prospects for future performance, (iii) publicly disclose results that are relevant to financial covenants included in MYR's credit facility and (iv) otherwise provide useful supplemental information that may be useful to investors in evaluating MYR.
