Organization, Consolidation and Presentation of Financial Statements [Abstract]

Interim Financial Statements

1.    Interim Financial Statements

Basis of Presentation. The Consolidated Financial Statements and related disclosures as of September 30, 2016, and for the three and nine months ended September 30, 2016 and 2015, are unaudited, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The December 31, 2015, 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, 2015, filed on Form 10-K with the SEC on February 22, 2016. The results of operations for the three and nine months ended September 30, 2016, 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 December 30, 2015, we increased our ownership in J-Devices to 100% (Note 3). As a result, our accounting for J-Devices changed from the equity method to the consolidation method effective December 30, 2015. The operating results of J-Devices were consolidated beginning in 2016.

Revision to Previously Reported Financial Information. In the second quarter of 2016, we identified an error in the provision for income taxes in the financial statements for J-Devices for the periods beginning in 2012 through the fourth quarter of 2015.  We believe that the error is not material to Amkor for the periods impacted and have elected to revise our previously issued consolidated financial statements.  Periods presented herein are based on the revised financial results. See Note 17 for additional information.

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.

Goodwill. The balance of goodwill in our Consolidated Balance Sheets reflects adjustments for foreign currency translation.
