NON-GAAP FINANCIAL MEASURES

The non-GAAP financial measures contained herein are a supplement to the corresponding financial measures prepared in accordance with U.S. GAAP. The non-GAAP financial measures presented exclude certain items that are more fully described in the Appendix. Management believes that adjustments for these items assist investors in making comparisons of period-to-period operating results. Furthermore, management also believes that these items are not indicative of the Company's on-going core operating performance. These non-GAAP financial measures have certain limitations in that they do not reflect all of the costs associated with the operations of the Company's business as determined in accordance with GAAP. Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. The non-GAAP financial measures presented by the Company may be different from the non-GAAP financial measures used by other companies. The Company has presented the following non-GAAP measures to assist investors in understanding the Company's core net operating results on an on-going basis: (i) constant currency product revenue growth %, (ii) non-GAAP gross profit/margin %, (iii) non-GAAP SG&A expense, (iv) non-GAAP R&D expense, (v) non-GAAP litigation settlement, award and/or defense costs, (vi) non-GAAP operating expense %, (vii) non-GAAP operating income/margin %, (viii) non-GAAP earnings per diluted share and (ix) adjusted free cash flow. These non-GAAP financial measures may also assist investors in making comparisons of the company's core operating results with those of other companies. Management believes constant currency product revenue growth, non-GAAP gross profit/margin, non-GAAP SG&A expense %, non-GAAP R&D expense %, non-GAAP litigation settlement, award and/or defense costs, non-GAAP operating expense %, non-GAAP operating income/margin, non-GAAP net income, non-GAAP net income per diluted share, and adjusted free cash flow are important measures in the evaluation of the Company's performance and uses these measures to better understand and evaluate our business.
