To supplement the consolidated financial results prepared in accordance with GAAP, onsemi uses certain non-GAAP measures, which are adjusted from the most directly comparable GAAP measures to exclude items related to the amortization of acquisition-related intangibles, expensing of appraised inventory fair market value step-up, inventory valuation adjustments, in-process research and development expenses, restructuring, asset impairments and other, net, goodwill impairment charges, gains and losses on debt prepayment, non-cash interest expense, actuarial (gains) losses on pension plans and other pension benefits, third party acquisition and divestiture-related costs, tax impact of these items and certain other non-recurring items, as necessary. Management does not consider the effects of these items in evaluating the core operational activities of onsemi. Management uses these non-GAAP measures internally to make strategic decisions, forecast future results and evaluate onsemi’s current performance. In addition, the Company believes that most analysts covering onsemi use the non-GAAP measures to evaluate onsemi's performance. Given management’s and other relevant parties' use of these non-GAAP measures, onsemi believes these measures are important to investors in understanding onsemi's current and future operating results as seen through the eyes of management. In addition, management believes these non-GAAP measures are useful to investors in enabling them to better assess changes in onsemi's core business across different time periods. These non-GAAP measures are not prepared in accordance with, and should not be considered alternatives or necessarily superior to, GAAP financial data and may be different from non-GAAP measures used by other companies. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies’ non-GAAP financial measures, even if they have similar names.

At an average stock price per share between $20.72 and $30.70 for the 1.625% Notes, $52.97 and $74.34 for the 0% Notes, and $103.87 and $156.78 for the 0.50% Notes, the hedging activity offsets the potentially dilutive effect of the 1.625% Notes, the 0% Notes, and the 0.50% Notes, respectively. In periods when the quarterly average stock price exceeds $30.70 for the 1.625% Notes, $74.34 for the 0% Notes, and $156.78 for the 0.50% Notes, the dilutive impact of the warrants issued concurrently with such notes are included in the diluted shares outstanding.
