We believe that the presentation of non-GAAP net income and non-GAAP earnings per diluted share provides important supplemental information regarding non-cash expenses, significant recurring items that we believe are important to understanding our financial, and business trends relating to our financial condition and results of operations. Non-GAAP net income and non-GAAP earnings per diluted share are among the primary indicators used by management as a basis for planning and forecasting future periods and by management and our board of directors to determine whether our operating performance has met specified targets and thresholds. Management uses non-GAAP net income and non-GAAP earnings per diluted share when evaluating operating performance because it believes that the exclusion of the items described below, for which the amounts and/or timing may vary significantly depending upon the Company's activities and other factors, facilitates comparability of the Company's operating performance from period to period. We have chosen to provide this information to investors so they can analyze our operating results in the same way that management does and use this information in their assessment of our business and the valuation of our Company.Use and Economic Substance of Non-GAAP Financial Measures used by Ubiquiti Networks We compute non-GAAP net income and non-GAAP diluted earnings per share by adjusting GAAP net income and GAAP earnings per diluted share to remove the impact of recurring stock-based compensation expense, income from a coexistence licensing agreement and the tax effect of these adjustments. In addition, our non-GAAP diluted earnings per share is calculated using weighted-average shares outstanding as if Series A preferred stock outstanding had been converted to common stock throughout the periods presented. Examples of items excluded from net income are:
- Recurring charges and gains, including: -- Stock-based compensation expense is recognized in accordance with FASB Accounting Standards Codification, Topic 718, Stock Compensation.
- Income from a coexistence licensing agreement
- Tax effect of non-GAAP adjustments. After adjusting to exclude the items described above, we apply the principles of ASC 740, Income Taxes, to estimate the non-GAAP income tax provision.
