Mark to market on marketable equity securities: We exclude gains and losses resulting from mark to market adjustments of our marketable equity securities when calculating certain non-GAAP measures as we do not believe the volatility generally associated with these securities correlates to our core operational performance. Consequently, our non-GAAP net income and earnings per share figures exclude these impacts to facilitate an evaluation of our current performance and comparisons to our past performance.

Gains or losses from divestiture: We exclude gains or losses resulting from the divestiture of Intel Security Group in the second quarter of 2017 and planned divestiture of Wind River in 2018. We have excluded these gains and related tax impacts for purposes of calculating certain non-GAAP measures. We believe making these adjustments facilitates a better evaluation of our current operating performance and comparisons to past operating results.

Free cash flow: We reference a non-GAAP financial measure of free cash flow, which is used by management when assessing our sources of liquidity, capital resources, and operating performance. We believe this non-GAAP financial measure is helpful to investors in understanding our capital structure and provides an additional means to reflect the cash flow trends of our business.
