NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)



1.    Interim Financial Statements

Basis of Presentation. The Consolidated Financial Statements and related disclosures as of June 30, 2019, and for the three and six months ended June 30, 2019 and 2018, are unaudited, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The December 31, 2018 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, 2018, filed on Form 10-K with the SEC on February 22, 2019. The results of operations for the three and six months ended June 30, 2019 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.

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.

Unbilled Receivables. Total unbilled receivables as of June 30, 2019 and December 31, 2018 were $88.7 million and $89.3 million, respectively.

2.    New Accounting Standards

Recently Adopted Standards

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which was subsequently amended and clarified. Topic 842 requires a dual approach for lease accounting under which a lessee would account for leases as finance leases or operating leases. The standard also requires the lessee to recognize a right-of-use asset and a corresponding lease liability for both finance leases and operating leases. For finance leases, the lessee recognizes interest expense and amortization of the right-of-use asset, and for operating leases, the lessee recognizes a straight-line lease expense. The standard permits the use of two alternative transition approaches, either with application in all comparative periods presented, or with application beginning with the effective date without restating comparative period financial statements.

Effective January 1, 2019, we adopted the requirements of Topic 842 using the modified transition approach without restating the comparative period financial statements. The new standard resulted in increases in our operating lease right of use asset, accrued expenses and long-term operating lease liability account balances to record our operating leases on our Consolidated Balance Sheet. The new standard also resulted in additional disclosures for our operating and finance leases (Note 10).

In accordance with Topic 842, we applied practical expedients permitted under the transition guidance, which allowed us to not:
Reassess whether any existing contracts are or contain a lease,
Reassess the lease classification for any existing contracts,
Reassess initial direct costs for any existing leases, and
Separate non-lease components from lease components and instead to account for them as a single lease component for all asset classes.

5.    Income Taxes

Income tax expense of $27.3 million for the six months ended June 30, 2019 reflects income taxes, foreign withholding taxes and minimum taxes. Income tax expense for the six months ended June 30, 2019 also includes a $14.9 million non-cash discrete tax expense primarily for the recognition of a valuation allowance for certain deferred tax assets.

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


- 9-


Table of Contents

AMKOR TECHNOLOGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
(Unaudited)



all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies and results of recent operations. Based on current projections of future taxable income in foreign jurisdictions, foreign deferred tax assets of $14.9 million are not expected to be realized, including certain tax credit carryforwards that are expected to expire unused.

We maintain a valuation allowance on a portion of our U.S. net deferred tax assets for deferred interest expense carryforwards, net operating loss carryforwards and foreign tax credit carryforwards that are expected to expire unused. 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 were $25.3 million at December 31, 2018 and $25.7 million as of June 30, 2019. 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 2012-2018. 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. Current examinations include income tax returns in the Philippines (2012-2013), Singapore (2014-2016) and Korea (2015-2018).

6.    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 and unvested restricted shares.

The following table summarizes the computation of basic and diluted EPS:

8.    Factoring of Accounts Receivable

For certain accounts receivable, we use non-recourse factoring arrangements with third-party financial institutions to manage our working capital and cash flows. Under this program, we sell receivables to a financial institution for cash at a discount to the face amount. As part of the factoring arrangements, we perform certain collection and administrative functions for the receivables sold. For the three and six months ended June 30, 2019, we sold receivables totaling $149.1 million and $304.8 million, net of discounts and fees of $1.1 million and $2.2 million, respectively. For the three and six months ended June 30, 2018, we sold receivables totaling $203.1 million and $428.6 million, net of discounts and fees of $2.0 million and $3.8 million, respectively.
