Pro Forma net income (earnings) per share

Management believes that net income per share before the impact of foreign currency translation gain or loss and income tax adjustments that materially impact the effective tax rate due to completion of tax audits and/or expiration of statutes is an important measure. The majority of the Company’s consolidated foreign currency gain or loss result from transactions involving the Euro, the British Pound Sterling and the Taiwan Dollar and from the exchange rate impact of the significant cash and marketable securities, receivables and payables held in U.S. dollars at the end of each reporting period by the Company’s various non-U.S. subsidiaries. Such gain or loss is required under GAAP because the functional currency of the subsidiaries differs from the currency in which various assets and liabilities are held. However, there is minimal cash impact from such foreign currency gain or loss. The Company’s income tax expense is periodically impacted by material reserve releases related to completion of audits and/or the expiration of statutes effecting prior periods. Thus, reported income tax expense is not reflective of the income tax expense that is incurred related to the current period earnings. The release of other uncertain tax position reserves, amounting to approximately $11 million in the first half of 2014 and $10 million in the first half of 2013, have not been included as pro forma adjustments in the following presentation of pro forma net income as such amounts have been considered immaterial, tend to be more recurring in nature and are comparable between periods. Accordingly, earnings per share before the impact of foreign currency translation gain or loss and income tax adjustments that materially impact the effective tax rate due to completion of tax audits and/or expiration of statutes permits a consistent comparison of the Company’s operating performance between periods.
