Interim Financial Statements

1.    Interim Financial Statements

Basis of Presentation. The Consolidated Financial Statements and related disclosures as of March 31, 2015, and for the three months ended March 31, 2015 and 2014, are unaudited, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The December 31, 2014, Consolidated Balance Sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S.”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. In our opinion, these financial statements include all adjustments (consisting only of normal recurring adjustments) necessary for the fair statement of the results for the interim periods. These financial statements should be read in conjunction with the financial statements included in our Annual Report for the year ended December 31, 2014, filed on Form 10-K with the SEC on February 19, 2015. The results of operations for the three months ended March 31, 2015, are not necessarily indicative of the results to be expected for the full year. Unless the context otherwise requires, all references to “Amkor,” “we,” “us,” “our” or the “company” are to Amkor Technology, Inc. and our subsidiaries.

On June 30, 2014, we completed the sale of our Japanese subsidiary to J-Devices, our equity-method joint venture in Japan. The financial results of the entity were included in our consolidated financial statements up to the date of sale (Note 3) and have subsequently been included in the results of J-Devices.

The U.S. dollar is our reporting currency and the functional currency for our subsidiaries. Effective June 30, 2014, we changed the functional currency for our sales office in Japan to the U.S. dollar primarily due to an increase in the mix of our U.S. dollar denominated sales. The change in functional currency is applied on a prospective basis.

Use of Estimates. The Consolidated Financial Statements have been prepared in conformity with U.S. GAAP, using management’s best estimates and judgments where appropriate. These estimates and judgments affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. The estimates and judgments will also affect the reported amounts for certain revenues and expenses during the reporting period. Actual results could differ materially from these estimates and judgments.
