In addition, certain non-GAAP financial information is used internally by management to evaluate and manage the company. As a note, the non-GAAP financial information used by Cirrus Logic may differ from that used by other companies. These non-GAAP measures should be considered in addition to, and not as a substitute for, the results prepared in accordance with GAAP.
