Use of Non-GAAP Financial Information

In addition to financial results determined in accordance with generally accepted accounting principles (“GAAP”), this press release refers to financial information determined by methods other than in accordance with GAAP, including non-GAAP gross margin, Income and Income (earnings) per share.  These non-GAAP financial measures adjust the Company's actual results prepared under GAAP to exclude charges and the related income tax effect for share-based compensation, the amortization of acquired intangible assets, manufacturing transition costs, employee severance costs, acquisition related costs, fair value adjustment to contingent consideration, purchase accounting inventory step-up included in cost of sales, the reduction of an uncertain tax position liability and related indemnification receivable and U.S. Tax Reform. The use of non-GAAP measures are not meant as a substitute for GAAP, but are included solely for informational and comparative purposes. The Company’s management believes that this information can assist investors in evaluating the Company’s operational trends, financial performance, and cash generating capacity. Management believes these non-GAAP measures allow investors to evaluate the Company’s financial performance using some of the same measures as management. These disclosures should not be viewed as a substitute for (or superior to) operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies.
