The reconciliation of basic earnings per share (EPS) presented above compares the quarter and year ended December 31, 2012 versus December 31, 2011 and is a non-GAAP presentation. The economic substance behind our non-GAAP EPS measure is to present the after tax impact of significant items and components of the statement of income on a per share basis before the impact of additional stock issuances. We believe this presentation is useful to investors because the statement of income does not readily show the EPS impact of the various components, including the effect of new stock issuances. This could limit the readers’ understanding of the reasons for the EPS change from previous years. This information is useful to management, and we believe useful to investors, to better understand the reasons for the fluctuation in EPS between the prior and current years on a per share basis.In addition, although a non-GAAP presentation, we believe the presentation of gross margin (reflected in the table above and elsewhere in this press release) is useful to investors and others in understanding and analyzing changes in our operating performance from one period to the next, and have included the analysis as a complement to the financial information we provide in accordance with GAAP. This reconciliation and margin information may not be comparable to other companies or more useful than the GAAP presentation included in the statements of income. We also note that this presentation does not purport to be an alternative to EPS determined in accordance with GAAP as a measure of operating performance or any other measure of financial performance presented in accordance with GAAP. Management compensates for the limitations of using non-GAAP financial measures by using them to supplement GAAP results to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone. The dilutive effect of additional shares issued in this table reflects the impact of all shares issued in the respective periods presented.
