Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

The Consolidated Financial Statements and related disclosures as of September 30, 2014, and for the three and nine months ended September 30, 2014 and 2013, are unaudited, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The December 31, 2013, 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, 2013, filed on Form 10-K with the SEC on February 28, 2014. The results of operations for the three and nine months ended September 30, 2014, 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 60% owned 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 4) and have subsequently been included in the results of J-Devices. On July 31, 2013, we completed the purchase of Toshiba Electronics Malaysia Sdn. Bhd. The financial results of the entity have been included in our Consolidated Financial Statements from the date of acquisition (Note 3).

The U.S. dollar is our reporting currency and the functional currency for our foreign 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.

Beginning with the year ended December 31, 2013, we reclassified equity in earnings of unconsolidated affiliate from other expense (income) to below income tax expense in our Consolidated Statements of Income for all periods presented. The reclassification had no impact on net income.

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.
