The Company uses the non-GAAP measures indicated in the Reconciliation to supplement the Company’s financial results presented on a GAAP basis. These non-GAAP measures exclude equity based compensation expenses, amortization of intangible assets, share in losses/profits of associated companies, as well as certain financial and other expenses and items that are believed to be helpful in understanding and comparing past operating and financial performance with current results. Management uses all of the non-GAAP measures to evaluate the Company’s operating and financial performance in light of business objectives and for planning purposes.  These measures are not in accordance with GAAP and may differ from non-GAAP methods of accounting and reporting used by other companies. Orbotech believes that these measures enhance investors’ ability to review the Company’s business from the same perspective as the Company’s management and facilitate comparisons with results for prior periods. In addition, these non-GAAP measures are among the primary factors management uses in planning for and forecasting future periods. However, the non-GAAP measures presented are subject to limitations as an analytical tool because they exclude certain recurring items (such as, equity compensation, financial expense and amortization of intangible assets) as described below and in the Reconciliation. The presentation of this additional non-GAAP information should not be considered in isolation or as a substitute for net income; net income attributable to Orbotech Ltd. or earnings per share prepared in accordance with GAAP, and should be read only in conjunction with the Company’s consolidated financial statements prepared in accordance with GAAP. For a quantification of the adjustments made to comparable GAAP measures, please see the Reconciliation.

The effect of equity-based compensation expenses has been excluded from the non-GAAP measures. Although equity-based compensation is a key incentive offered to employees, and the Company believes such compensation contributed to the revenues earned during the periods presented and also believes it will contribute to the generation of future period revenues, the Company continues to evaluate its business performance excluding equity based compensation expenses. Equity-based compensation expenses will recur in future periods.

The effects of amortization of intangible assets have also been excluded from the measures. This item is inconsistent in amount and frequency and is significantly affected by the timing and size of acquisitions and dispositions. Investors should note that the use of intangible assets contributed to revenues earned during the periods presented and will contribute to future period revenues as well. Amortization of intangible assets will recur in future periods and the
