Use of Non-GAAP Financial Metrics and Additional Financial InformationIn addition to reporting financial results in accordance with generally accepted accounting principles, or GAAP, STRATTEC provides Adjusted Non-GAAP information as additional information for its operating results. References to Adjusted Non-GAAP information are to non-GAAP financial measures. These measures are not required by, in accordance with, or an alternative for, GAAP and may be different from non-GAAP financial measures used by other companies. STRATTEC’s management uses these measures for reviewing the financial results of STRATTEC for budget planning purposes and for making operational and financial decisions. Management believes that providing these non-GAAP financial measures to investors, as a supplement to GAAP financial measures, help investors evaluate STRATTEC’s core operating and financial performance and business trends consistent with how management evaluates such performance and trends. Additionally, management believes these measures facilitate comparisons with the core operating and financial results and business trends of competitors and other companies. The Company has provided reconciliations of comparable GAAP to non-GAAP measures in the supplemental slides of this presentation.
