NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1.    Interim Financial Statements
Basis of Presentation. The Consolidated Financial Statements and related disclosures as of June 30, 2023, and for the three and six months ended June 30, 2023 and 2022, contained in this Form 10-Q (the “Consolidated Financial Statements”) are unaudited pursuant to the rules and regulations of the SEC. The December 31, 2022 Consolidated Balance Sheet data contained in this Form 10-Q 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. GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to SEC rules and regulations. In our opinion, the Consolidated Financial Statements include all adjustments (consisting only of normal recurring adjustments) necessary for the fair statement of the results for the interim periods and should be read in conjunction with the financial statements included in the 2022 Form 10-K. The results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results to be expected for the full year ending December 31, 2023. Unless the context otherwise requires, all references to “Amkor,” “we,” “us” or “our” are to Amkor Technology, Inc. and its wholly and majority-owned subsidiaries.
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 as a result of, for example, any worsening of the global business and economic environment.
Goodwill. The balance of goodwill in the Consolidated Balance Sheets contained in this Form 10-Q reflects adjustments for foreign currency translation.
Unbilled Receivables. Total unbilled receivables as of June 30, 2023 and December 31, 2022 were $268.3 million and $301.7 million, respectively.
Contract Liabilities. Contract liabilities were $150.5 million and $170.6 million as of June 30, 2023 and December 31, 2022, respectively. As of June 30, 2023 and December 31, 2022, the short-term portions of the liabilities were $75.9 million and $81.5 million, respectively. The remainder of the June 30, 2023 contract liability balance is expected to be recognized in revenue over the next 1-5 years. Revenue recognized during the six months ended June 30, 2023 and 2022 that was included in the contract liabilities balance at the beginning of the period was $39.2 million and $55.7 million, respectively.

4.    Income Taxes
Income tax expense of $20.3 million for the six months ended June 30, 2023 reflects income taxes, foreign withholding taxes and minimum taxes. In July 2023, our subsidiary in Singapore was granted a renewal of a reduced tax rate through the end of 2028, subject to certain conditions and commitments.
We monitor on an ongoing basis our ability to utilize our deferred tax assets and whether there is a need for a related valuation allowance. In evaluating our ability to recover our deferred tax assets in the jurisdictions from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies and recent results of operations.
We maintain a valuation allowance on certain U.S. and foreign deferred tax assets. Such valuation allowances are released as the related tax benefits are realized or when sufficient evidence exists to conclude that it is more likely than not that the deferred tax assets will be realized.
Unrecognized tax benefits represent reserves for potential tax deficiencies or reductions in tax benefits that could result from federal, state or foreign tax audits. Gross unrecognized tax benefits decreased from $33.3 million as of December 31, 2022 to $31.0 million as of June 30, 2023. All of our unrecognized tax benefits would reduce our effective tax rate if recognized. Our unrecognized tax benefits are subject to change for effective settlement of examinations, changes in the recognition threshold of tax positions, the expiration of statutes of limitations and other factors.
We have tax returns that are open to examination in various jurisdictions for tax years 2013-2022. The open years contain matters that could be subject to differing interpretations of applicable tax laws and regulations related to the amount and/or timing of income, deductions and tax credits. There can be no assurance that the outcome of the examinations will be favorable. In certain circumstances where we elect to appeal the results of an examination, we may be required to make tax assessment payments to proceed with the administrative appeal process.

5.    Earnings Per Share
Basic earnings per share (“EPS”) is computed by dividing net income attributable to Amkor common stockholders by the weighted-average number of common shares outstanding during the period. The weighted-average number of common shares outstanding is reduced for treasury stock.
Diluted EPS is computed based on the weighted-average number of common shares outstanding plus the effect of dilutive potential common shares outstanding during the period. Dilutive potential common shares include outstanding stock options, performance-vested restricted stock units, time-vested restricted stock units and unvested restricted shares.
The following table summarizes the computation of basic and diluted EPS:
