1.	Basis of Presentation

The condensed consolidated balance sheets as of June 30, 2012 and December 31, 2011, the condensed consolidated statements of income and comprehensive income for the three and six months ended June 30, 2012 and July 1, 2011, and the condensed consolidated statements of cash flow and stockholders’ equity for the six months ended June 30, 2012 and July 1, 2011 have been prepared by the Company. In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position at June 30, 2012 and results of operations and cash flow for all periods presented have been made.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011 (the “Form 10-K”). The results of operations for the three and six months ended June 30, 2012 are not necessarily indicative of the operating results for the full year.

Beginning January 1, 2012, the Company changed its 4 week - 4 week - 5 week quarterly reporting calendar to a month-end quarterly calendar. This change will eliminate differences in the number of days in the first and fourth quarters of the year, when the Company provides year-over-prior year comparisons beginning in 2013. These differences will not have a material effect on the comparative results of the quarterly periods in 2012 and 2011.

On June 1, 2011, the Company effected a two-for-one stock split of the Company’s Common Stock in the form of a 100% stock dividend. All applicable amounts in the consolidated financial statements, including earnings per share and related disclosures, have been retroactively adjusted to reflect the stock split.

The Company incurred research and development expenses in the second quarter of 2012 and 2011 of $13.9 million and $13.1 million, respectively. The Company incurred research and development expenses in the first six months of 2012 and 2011 of $26.5 million and $25.6 million, respectively. These expenses are included in selling, general and administrative expenses.
