Use and Economic Substance of the Non-GAAP Financial Measures-Management uses these non-GAAP measures to evaluate performance period over period, to analyze the underlying trends in the Company's business, to assess its on-going operating performance relative to its competitors, and to establish operational goals and forecasts. Share-based compensation expense is excluded as a non-cash expense that the Company does not believe is reflective of ongoing operating results and which is an amount excluded from calculations of earnings per share used in measuring its achievement of performance targets required for vesting performance-based share awards. Net costs and expenses related to the Processing System Intrusion are not indicative of the Company's on-going operating performance and are therefore excluded by management in assessing the Company's operating performance, as well as from the measures used for making operating decisions.The following is an explanation of the adjustments that management excluded as part of its non-GAAP measures for the three months ended June 30, 2012 and 2011:
- Share-based compensation expense is non-cash expense that the Company does not believe is reflective of ongoing operating results;
- Share-based compensation expense is excluded from calculations of earnings per share used in measuring its achievement of performance targets required for vesting performance-based awards; and
- The Company's use of performance-based share awards has increased significantly in recent years, with the result that reported share-based compensation expense can vary significantly from year to year, or quarter to quarter, in ways that may not be related to the underlying operating performance of the Company.
