Basis of Presentation

The condensed consolidated financial data at December 31, 2018 is derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018 filed with the Securities and Exchange Commission (“SEC”) on February 21, 2019 (“Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, operating results and cash flows in conformity with GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in our Form 10-K.  All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the operating results for the period presented have been included in the interim period. Operating results for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2019.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. As permitted under GAAP, interim accounting for certain expenses, including income taxes, are based on full year forecasts. For interim financial reporting purposes, income taxes are recorded based upon estimated annual effective income tax rates taking into consideration discrete items occurring in a quarter.

Dollar amounts and share amounts are presented in thousands, except per share amounts, unless otherwise noted. Certain prior year’s balances may have been reclassified to conform to the current financial statement presentation.

Recently Issued Accounting Pronouncements

The Financial Accounting Standards Board (“FASB”) issued the following Accounting Standards Updates (“ASU”) which could have potential impact on the Company’s financial statements:   

-8-

Recently Adopted Standards

ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”) – In February 2016, the FASB issued ASU 2016-02, which amends the accounting treatment for leases and requires, among other things, lessees to recognize a right-of-use (“ROU”) asset and lease liability for most lease arrangements. The amendments were effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company adopted ASU 2016-02 on January 1, 2019, using the modified retrospective transition approach, under which financial results reported in periods prior to 2018 are unchanged. We elected the following allowed practical expedients as permitted under the transition guidance within the new standard:

• Not record leases with an initial term of 12 months on the balance sheet;

• Not separate non-lease components of leases from the lease components; and

• Not reassess (1) the definition of a lease, (2) lease classification, and (3) initial direct costs for existing leases during transition.

Upon adoption of ASU 2016-02, the Company recorded ROU assets of $68.3 million, including land-use rights of $17.1 million previously recorded in other assets and $2.5 million previously recorded in property, plant and equipment and ROU liabilities of $50.4 million. For additional information related to the Company’s leases, see Note 10.    

ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting ("ASU 2018-07") - In June 2018, the FASB issued ASU 2018-07, which simplifies several aspects of the accounting for nonemployee share-based payment transactions resulting from expanding the scope of Topic 718, Compensation—Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 was effective for the Company on January 1, 2019. The adoption of this standard did not have a material effect on our condensed consolidated financial statements or disclosures.

ASU No. 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”) -In August 2017, the FASB issued ASU No. 2017-12 to better align hedge accounting with risk management strategies, and as a result, more hedging strategies will be eligible for hedge accounting. Public business entities will have until the end of the first quarter in which a hedge is designated to perform an initial assessment of a hedge’s effectiveness. After initial qualification, the new guidance permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test if the company can reasonably support an expectation of high effectiveness throughout the term of the hedge. An initial quantitative test to establish that the hedge relationship is highly effective is still required. The amendments are effective for fiscal years beginning after December 15, 2018, and the Company adopted the new standard January 1, 2019. The new standard had no impact on the Company’s financial statements.

On January 1, 2019, the Company adopted ASU No. 2018-16, “Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes”. The amendments in this ASU permit the use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under ASC 815, in addition to the currently permissible benchmark interest rates. This ASU provides the Company the ability to utilize the OIS rate based on SOFR as the benchmark interest rate on certain hedges of interest rate risk. The new standard had no impact on the Company’s financial statements.

Standards Effective in Future Years

The FASB has issued the following relevant standards, effective in future years, which are not expected to have a material impact on our consolidated condensed financial statements:

Standard No.	Standard Name	Standard Effective Date
2018-13	Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement	January 1, 2020
2018-14	Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans	January 1, 2020

In April 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, that clarifies and improves areas of guidance related to the recently issued standards on credit losses (ASU 2016-13), hedging (ASU 2017-12), and recognition and measurement of financial instruments (ASU 2016-01). The amendments generally have the same effective dates as their related standards. If already adopted, the amendments of ASU 2016-01 and ASU

-9-

2016-13 are effective for fiscal years beginning after December 15, 2019 and the amendments of ASU 2017-12 are effective as of the beginning of the Company’s next annual reporting period; early adoption is permitted. The Company is currently evaluating the impact this change will have on its consolidated financial statements and disclosures.    

All other issued and not yet effective accounting standards are not expected to be relevant to the Company.

Updates to Accounting Policies and Estimates

Leases

The Company determines if an arrangement is a lease at inception. ROU assets are included in Other assets in the Company’s condensed consolidated balance sheets. Current ROU liabilities are included in Accrued liabilities and other and long-term ROU liabilities are included in Other long-term liabilities, in our condensed consolidated balance sheets.

ROU assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. To determine the present value of the lease payments, we estimate our incremental borrowing rate based on information available at the lease commencement date.

The Company’s lease term includes options to extend the lease when it is reasonably certain that it will exercise that option. Leases with a term of 12 months or less are not recorded on the balance sheet. Our leases typically do not contain any residual value guarantees.  For real estate, we account for the lease and non-lease components as a single lease component.

NOTE 2 – Earnings per Share

Earnings per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted-average number of shares of Common Stock outstanding during the period. Diluted EPS is calculated similarly but includes potential dilution from the exercise of stock options and stock awards, except when the effect would be anti-dilutive.  During the three and six months ended June 30, 2019 and 2018 we paid no dividends on our Common Stock.

The table below sets forth the reconciliation between net income and the weighted average shares outstanding used for calculating basic and diluted EPS:

NOTE 4 – Goodwill and Intangible Assets

The table below sets forth the changes in goodwill:

Balance at December 31, 2018	$	132,437
Acquisitions:
Wafer fabrication facility in Greenock, Scotland (a)		931
Canyon investment (b)		1,443
ERIS investment in Yea-Shin (c)		4,320
Foreign currency translation adjustment		(359	)
Balance at June 30, 2019	$	138,772

The increase in goodwill is related to:

(a)  The Company’s acquisition accounting for the purchase of a wafer fabrication facility in Greenock, Scotland, (“GFAB”).  (See Note 13 for additional information).

(b)  The acquisition accounting for the Company’s investment of $3.4 million in Canyon Semiconductor.  This investment brings our ownership of Canyon to 51%.  During the second quarter of 2019, as a measurement period adjustment, we reduced the amount of goodwill approximately $1.1 million. This reduction in goodwill was related to finalization of the non-controlling interest value. The acquisition accounting is not final as deferred taxes are being finalized.  We expect the acquisition accounting to be finalized in the third quarter of 2019.   

(c)  The acquisition accounting related to Eris’ investment of approximately $6.4 million in Yea-Shin Technology Corporation.  During the second quarter of 2019, as a measurement period adjustment, we increased goodwill approximately $4.3 million, related to finalization of deferred taxes. The Company owns approximately 51% of Eris and Eris owns approximately 60% of Yea-Shin.    

The table below sets forth the value of intangible assets, other than goodwill:

NOTE 5 – Income Tax Provision

The table below sets forth information related to our income tax expense:  

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2019			2018			2019			2018
Domestic pre-tax income (loss)	$	8,064		$	5,350		$	20,550		$	(4,022	)
Foreign pre-tax income	$	39,813		$	31,070		$	69,361		$	66,745
Income tax provision	$	11,174		$	10,753		$	21,472		$	18,536
Effective tax rate		23.3	%		29.5	%		23.9	%		29.6	%
Impact of tax holidays on tax expense	$	572		$	70		$	849		$	(742	)
Earnings per share impact of tax holidays:
Basic	$	(0.01	)	$	-		$	(0.02	)	$	0.01
Diluted	$	(0.01	)	$	-		$	(0.02	)	$	0.01

The decrease in the effective tax rate for the three and six months ended June 30, 2019 when compared to the three and six months ended June 30, 2018, is primarily attributable to an increase in estimated full year global pretax book income and a net decrease in unfavorable U.S. permanent differences.         

Our undistributed foreign earnings continue to be indefinitely reinvested in foreign operations, with limited exceptions related to earnings of European and Asian subsidiaries.  Any future distributions of foreign earnings will not be subject to additional U.S. income tax, but may be subject to non-U.S. withholding taxes.

We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. We are no longer subject to U.S. federal income tax examinations by tax authorities for tax years before 2008, or for the 2010 and 2011 tax years. We are no longer subject to China income tax examinations by tax authorities for tax years before 2009. With respect to state and local jurisdictions and countries outside of the U.S. (other than China), with limited exceptions, the Company is no longer subject to income tax audits for years before 2013. Although the outcome of tax audits is always uncertain, the Company believes that adequate amounts of tax, interest and penalties, if any, have been provided for in the Company’s reserve for any adjustments that may result from currently pending tax audits. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in interest expense. As of June 30, 2019, the gross amount of unrecognized tax benefits was approximately $35.9   million. 

It is reasonably possible that the amount of the unrecognized benefit with respect to certain of the Company’s unrecognized tax positions will significantly increase or decrease within the next 12 months. At this time, an estimate of the range of the reasonably possible outcomes cannot be made.

NOTE 6 – Share-Based Compensation

Stock Options. Approximately $6.7 million in cash proceeds was received from stock option exercises during the six months ended June 30, 2019.

As of June 30, 2019, we had no unrecognized share-based compensation expense related to unvested stock options.  

Share Grants. Restricted stock awards and restricted stock units generally vest in equal annual installments over a four-year period.   We also have share grants that are performance-based and time-based that vest upon achievement of certain performance criteria over time.             

As of June 30, 2019, total unrecognized share-based compensation expense related to share grants was approximately $38.9 million, before income taxes, and is expected to be recognized over a weighted average period of approximately 2.2 years.          

NOTE 7 – Segment Information and Net Sales

Segment Reporting. For financial reporting purposes, we operate in a single segment, standard semiconductor products, through our various manufacturing and distribution facilities. We aggregate our products because the products are similar and have similar economic characteristics, use similar production processes and share the same customer type. Our primary operations include operations in Asia, North America and Europe.  During the three months ended June 30, 2019 and 2018, one customer, a broad-based global distributor that sells to thousands of different end users, accounted for 10% or $31.5 million and 10.9% or $33.3 million, respectively, of our net sales.  During the six months ended June 30, 2018, the same customer accounted for 10.7% or $61.7 million of our net sales. This customer did not account for 10% or greater of our outstanding accounts receivable at June 30, 2019 or 2018.

Disaggregation of Net sales. We disaggregate net sales from contracts with customers into direct sales and distribution sales (“Distributors”) and by geographic area. Direct sales customers consist of those customers using our product in their manufacturing process, and Distributors are those customers who resell our products to third parties. We sell our products to customers in multiple areas of the world including Asia, Europe, and North America. Across these regions, we sell products to end users in a variety of markets such as consumer electronics, computing, communications, industrial and automotive. Further, most of our contracts are fixed-price arrangements, and are short term in nature, ranging from days to several months.

NOTE 8 – Commitments and Contingencies

Purchase commitments – As of June 30, 2019, we had approximately $18.5 million in non-cancelable purchase contracts related to capital expenditures, primarily related to our manufacturing facilities in Asia.  As of June 30, 2019, we also had a commitment to purchase approximately $83.7 million of wafers to be used in our manufacturing process.  These wafer purchases will occur during 2019 and 2020.

Defined Benefit Plan - We have a contributory defined benefit plan that covers certain employees in the United Kingdom.  As of June 30, 2019, the unfunded liability for this defined benefit plan was approximately $27.7 million.  We are obligated to make annual contributions, each year through December 2029, of approximately GBP 2 million (approximately $2.6  million based on a GBP: USD exchange rate of 1.3:1).  The trustees are required to review the funding position every three years, and the most recent review was carried out in April 2019.  We anticipate receiving the outcome of the April 2019 review during the third quarter of 2019. The outcome of future reviews can result in a change in the amount of the payment.  

-16-

Contingencies – From time to time, we are involved in various legal proceedings that arise in the normal course of business. While we intend to defend any lawsuit vigorously, we presently believe that the ultimate outcome of any pending legal proceeding will not have any material adverse effect on our consolidated financial position, cash flows or operating results. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which could impact our business and operating results for the period in which the ruling occurs or future periods.  Based on information available, we evaluate the likelihood of potential outcomes of all pending disputes. We record an appropriate liability when the amount of any liability associated with a pending dispute is deemed probable and reasonably estimable. In addition, we do not accrue for estimated legal fees and other directly related costs as they are expensed as incurred.  The Company is not currently a party to any pending litigation that the Company considers material.

Note 9 – Derivative Financial Instruments

We use derivative instruments to manage risks related to foreign currencies, interest rates and the net investment risk in our foreign subsidiaries. Our objectives for holding derivatives include reducing, eliminating, and efficiently managing the economic impact of these exposures as effectively as possible. Our derivative programs include strategies that both qualify and do not qualify for hedge accounting treatment.

Hedges of Foreign Currency Risk - We are exposed to fluctuations in various foreign currencies against our different functional currencies. We use foreign currency forward agreements to manage this exposure. At June 30, 2019, we had outstanding foreign currency forward contracts that are intended to preserve the economic value of foreign currency denominated monetary assets and liabilities; these instruments are not designated for hedge accounting treatment in accordance with ASC 815.  The fair value of these instruments approximates zero. 

The table below sets forth outstanding foreign currency forward contracts at June 30, 2019 and December 31, 2018:

Hedges of Interest Rate and Net Investment Risk - The Company’s objective in using interest rate swaps and collars is to minimize the risks associated with its floating rate debt. The Company makes use of cross currency swaps to decrease the foreign exchange risk inherent in the Company’s investment in its foreign subsidiaries. To accomplish these objectives, the Company uses the instruments detailed in the table below, measured in U.S. dollar equivalents:

	Number of Instruments		Notional Amount
	June 30, 2019	December 31, 2018	June 30, 2019		December 31, 2018

We estimate that $0.6 million of net derivative gains included in accumulated other comprehensive income (“AOCI”) as of June 30, 2019 will be reclassified into earnings within the following 12 months. No gains or losses were reclassified from AOCI into earnings as a result of forecasted transactions that failed to occur during three months ended June 30, 2019 or 2018.

NOTE 11 – Employee Benefit Plans  

Deferred Compensation

We maintain a Non-Qualified Deferred Compensation Plan (the “Deferred Compensation Plan”) for executive officers, key employees and members of the Board of Directors. The Deferred Compensation Plan allows eligible participants to defer the receipt of eligible compensation, including equity awards, until designated future dates. We offset our obligations under the Deferred Compensation Plan by investing in the actual underlying investments. These investments are classified as trading securities and are carried at fair value. At June 30, 2019 and December 31, 2018, these investments totaled approximately $10.1 million and $10.6 million, respectively. All gains and losses in these investments are materially offset by corresponding gains and losses in the Deferred Compensation Plan liabilities.

NOTE 12 – Related Parties

We conduct business with a related party company, Lite-On Semiconductor Corporation and its subsidiaries and affiliates (collectively, “LSC”), and Nuvoton Technology Corporation and its subsidiaries and affiliates (collectively, “Nuvoton”). LSC is our largest stockholder, owning approximately 15% of our outstanding Common Stock as of June 30, 2019, and is a member of the Lite-On Group of companies. Raymond Soong, the Chairman of our Board of Directors, is the Chairman of LSC, and is the Chairman of Lite-On Technology Corporation (“LTC”), a significant shareholder of LSC. C.H.

Note 13 – Wafer Fabrication Plant Acquisition

On April 1, 2019, the Company completed the previously announced acquisition of a wafer fabrication facility (“GFAB”) located in Greenock, Scotland.  The Company recorded the purchase of GFAB as a business acquisition. The Company purchased GFAB in order to increase the Company’s wafer production capacity.  Total consideration paid by the Company was $33.2 million and was funded by advances under the revolving portion of our long-term credit facility.  The facility and assets were wholly acquired, and there is no remaining minority interest.    The goodwill will not be tax deductible.  The Company also incurred acquisition costs of approximately $0.6 million that were recognized in selling, general and administrative expense.  Due to a lack of data we are unable to provide historical financial pro forma data.  The table below sets forth the fair value of the assets and liabilities recorded in the GFAB acquisition and the corresponding line item in which the item is recorded in our condensed consolidated balance sheet.

Property, plant and equipment, net	$	24.4
Inventories		3.6

Note 14 – Assets Held for Sale

Assets held for sale consist of approximately 16 acres of raw land located in Plano, Texas, that the Company is in the process of selling.  The land was originally acquired as a site to construct a future corporate headquarters. The Company decided that its existing headquarters is adequate and construction of a new headquarters building is not necessary.  The Company has been actively marketing the land and has a signed contract to sell the land to an unaffiliated third party for cash.  During the second quarter of 2019, the buyer received necessary local zoning approval for its building plans.  We anticipate the sale will close within the next 12 months.  We have not recorded any impairment charges in connection with the land.

Overview

We are a leading global manufacturer and supplier of high-quality, application-specific standard products within the broad discrete, logic, analog and mixed-signal semiconductor markets. For detailed information, see Note 1 – Nature of Operations, Basis of Presentation, Recently Issued Accounting Pronouncements and Updates to Accounting Policies and Estimates, included in the condensed consolidated financial statements in Item 1 above.  Our products are sold primarily throughout Asia, North America and Europe. We believe that our focus on application-specific standard products utilizing innovative, highly efficient packaging and cost-effective process technologies, coupled with our collaborative, customer-focused product development, provides us with a meaningful competitive advantage relative to other semiconductor companies.

Factors Relevant to Our Results of Operations for the Three Months Ended June 30, 2019

• During the second quarter of 2019, net sales were $322.0 million, an increase of 5.9% from the $304.1 million in the second quarter of 2018 due to continued market share gains, and an increase of 6.5% from the $302.3 million in the first quarter of 2019;

• Gross profit was $122.0 million, compared to $107.3 million of gross profit in the second quarter of 2018 and $112.4 million in the first quarter of 2019;

• Gross profit margin was 37.9%, compared to gross profit margin of 35.3% in the second quarter of 2018 and 37.2% in the first quarter of 2019;

• Net income was $36.3 million, or $0.70 per diluted share, compared to net income of $25.1 million, or $0.49 per diluted share, in the second quarter of 2018 and net income of $31.7 million, or $0.62 per diluted share, in the first quarter of 2019; and

• Cash flow from operations was $40.6 million.  Net cash flow was a negative $65.5 million, which includes a paydown of $44.1 million of long-term debt and $32.1 million of capital expenditures.

Recent Developments

April 1, 2019, we announced the closing of the previously announced agreement to acquire Texas Instruments’ (“TI”) wafer fabrication facility and operation located in Greenock, Scotland (“GFAB”). We are in the process of installing Diodes’ processes to fully use the additional 8” capacity and capability of GFAB, which we believe will support our growth expansion initiatives and future cost reduction initiatives.

Net sales increased approximately $17.9 million for the three months ended June 30, 2019, compared to the same period last year due to continued strong performance in Europe and North America as well as the automotive and industrial end markets. For the three months ended June 30, 2019, combined net sales in the automotive and industrial markets represented 39% of total sales.  Excluding the frequency control business, our serial-connectivity business reached record levels of net sales in the first three months of 2019.  

The table below sets forth our revenue as a percentage of total revenue by end-user market for the three months ended June 30, 2019 and 2018:

Cost of goods sold increased approximately $3.2 million for the three months ended June 30, 2019, compared to the same period last year.  As a percent of sales, cost of goods sold was 62.0% for the three months ended June 30, 2019, compared to 64.7% for the same period last year. Average unit cost increased approximately 4.7% for the three months ended June 30, 2019, compared to the same period last year. For the three months ended June 30, 2019, gross profit increased approximately 13.7% when compared to the same period last year. Gross profit margin for the three month periods ended June 30, 2019 and 2018 was 37.9% and 35.3%, respectively. The increase in gross profit margin was due to higher revenue contribution from the automotive and industrial markets as well as serial-connectivity products, which typically have higher gross profit margins.

Operating expenses for the three months ended June 30, 2019, increased approximately $4.0 million, or 5.8%, compared to the three months ended June 30, 2018. Selling, general and administrative expenses (“SG&A”) increased approximately $5.2 million and research and development expenses (“R&D”) decreased approximately $0.3 million. Amortization of acquisition related intangibles decreased $0.1 million. SG&A, as a percentage of sales, was 14.7% and 13.9% for the three months ended June 30, 2019 and 2018, respectively. R&D, as a percentage of sales, was 6.7% and 7.3% for the three months ended June 30, 2019 and 2018, respectively.  

Interest income increased 42.9% for the three months ended June 30, 2019, compared to the same period last year, due to interest received on cross currency swaps.  Interest expense decreased 21.0% for the three months ended June 30, 2019, compared to the same period last year. The decrease in interest expense for the three months ended June 30, 2019 was due to lower levels of debt partially offset by higher interest rates on the floating rate portion of the borrowings used to effect the Pericom acquisition in the fourth quarter of 2015. Foreign currency (loss) gain, net was a net loss of $0.5 million for the three months ended June 30, 2019, compared to a net gain of $0.3 million for the same period last year, reflecting the effectiveness of our currency hedges.

We recognized income tax expense of approximately $11.1 million and $10.8 million for the three months ended June 30, 2019 and 2018, respectively. The increase in income taxes for 2019 compared to 2018 was primarily attributable to an increase in pretax book income, partially offset by a net decrease in unfavorable U.S. permanent differences.

-26-

We recognized an income tax expense of approximately $21.4 million and $18.6 million for the six months ended June 30, 2019 and 2018, respectively. The increase in income taxes for 2019 compared to 2018 is primarily attributable to an increase in pretax book income, partially offset by a net decrease in unfavorable U.S. permanent differences.  

Financial Condition

Liquidity and Capital Resources

Our primary sources of liquidity are cash and cash equivalents, funds from operations and, if necessary, borrowings under our credit facilities.

Short-term debt

Our Asia subsidiaries maintain credit facilities with several financial institutions through our foreign entities worldwide totaling $121.4 million. At June 30, 2019, borrowings were $15.5 million and letters of credit were $0.4 million under the Asia credit facilities. Other than two Taiwanese credit facilities that are collateralized by assets, our foreign credit lines are unsecured, uncommitted, repayable on demand, terminable by the lender at any time and contain no restrictive covenants.  These credit facilities bear interest at LIBOR or similar indices plus a specified margin.  Interest payments are due quarterly on outstanding amounts under the credit lines. In addition to our credit lines, our 51% owned subsidiary, ERIS Technology Corporation (“ERIS”), borrowed $19.6 million on a long-term basis from local Taiwan banks in order to make an investment.  The first loan of $4.3 million matures in 2033, while the second loan of $15.3 million matures in 2024.

Long-term debt

We currently have a U.S. banking credit facility (the “U.S. Credit Facility”) under which we may draw up to $250 million on a revolving basis, in addition to a $250 million term loan.  The U.S. Credit Facility matures October 26, 2021.  The remaining portion of the term loan of the U.S. Credit Facility is repayable in part through quarterly installments that increase over time from $6.3 million in the first three quarters of 2019 to $9.4 million per quarter in the final year of the U.S. Credit Facility. We may, from time to time, request increases in the aggregate commitments under the U.S. Credit Facility of up to $200 million, subject to the lenders electing to increase their commitments or by means of the addition of new lenders, and subject to at least half of each increase in aggregate commitments being in the form of term loans, with the remaining amount of each increase being an increase in the amount of the revolving portion of the U.S. Credit Facility.  The U.S. Credit Facility contains certain financial and non-financial covenants, including, but not limited to, a maximum consolidated leverage ratio, a minimum consolidated fixed charge coverage ratio, and restrictions on liens, indebtedness, investments, fundamental changes, dispositions, and restricted payments (including dividends and share repurchases).  The obligations of the Company and the other borrowers under the U.S. Credit Facility are secured by substantially all of the assets of the Company, including controlling interests in its first-tier subsidiaries, and by specified assets of certain of its subsidiaries.

Less: Current portion of long-term debt	(29,988)
Less: Unamortized debt issuance costs	(1,174)
Total long-term debt, net of current portion	$141,919

Our primary liquidity requirements have been to meet our inventory and capital expenditure needs and to fund on-going operations. At June 30, 2019 and December 31, 2018, our working capital was $481.2 million and $480.8 million, respectively. We expect cash generated by our operations together with existing cash, cash equivalents, short-term investments and available credit facilities to be sufficient to cover cash needs for working capital and capital expenditures for at least the next 12 months.  

Capital expenditures for the six months ended June 30, 2019 and 2018 were $52.7 million and $47.5 million, respectively.  For the first six months of 2019 capital expenditures were approximately 8.4% of our net sales, which is in line with our capital spending target range of 5% to 9% of net sales.  

Our undistributed foreign earnings continue to be indefinitely reinvested in foreign operations, with limited exceptions related to earnings of European subsidiaries.  As of June 30, 2019, our foreign subsidiaries held approximately $128.0 million of cash, cash equivalents and investments of which approximately $21.4 million would be subject to a potential non-U.S. withholding tax if distributed outside the country in which the cash is currently held.  Of this total, $11.6 million is held in China.

As of June 30, 2019, we had short-term investments totaling $6.6 million. These investments are highly liquid with maturity dates greater than three months at the date of purchase. We generally can access these investments in a relatively short time frame but in doing so we generally forfeit all earned and future interest income.

Share Repurchase Program

During 2015, our Board of Directors (“Board”) approved a stock repurchase program.  The Board authorized the repurchase of up to an aggregate of $100.0 million of our outstanding Common Stock.  The share repurchase program is expected to continue through the end of 2019 unless extended or shortened by the Board.  Currently there is approximately $62.3 million available for repurchase of outstanding Common Stock under this publicly announced repurchase program.  No shares were repurchased during the three months ended June 30, 2019.

Discussion of Cash Flow

Our primary source of liquidity is cash flow from operations. Additional sources of liquidity are cash and cash equivalents, short-term investments and our credit facilities. Our cash and cash equivalents decreased from $241.1 million at December 31, 2018 to $235.4 million at June 30, 2019.  

The table below sets forth a summary of the condensed consolidated statements of cash flows:

Net decrease in cash and cash equivalents, including restricted cash	$	(5,019	)	$	(51,429	)	$	46,410

Operating Activities

Net cash flows provided by operating activities for the six months ended June 30, 2019 was $110.5 million.  Net cash flows provided by operating activities resulted from net income of $68.4 million, depreciation and amortization of intangible assets of $54.4 million, share-based compensation of $9.8 million and a decrease in noncash working capital accounts of $21.5 million. Cash flows from operating activities for the six months ended June 30, 2018 was $88.4 million.  Cash flows from operating activities resulted from net income of $44.2 million, depreciation and amortization of $51.3 million, share-based compensation of $11.1 million and a decrease in noncash working capital accounts of $17.6 million.

Investing Activities

Net cash and cash equivalents used in investing activities was $82.5 million for the six months ended June 30, 2019. Net cash and cash equivalents used in investing activities was primarily due to the purchase of property, plant and equipment of $50.7 and the acquisition of GFAB for $33.2 million during the six months ended June 30, 2019. Net cash and cash equivalents used in investing activities was $53.6 million for the six months ended June 30, 2018. Net cash and cash equivalents used in investing activities was primarily due to the purchase of property, plant and equipment of $53.0 million during the six months ended June 30, 2018.

Financing Activities

Net cash and cash equivalents used in financing activities was $33.0 million for the six months ended June 30, 2019. Net cash used in financing activities in the six months ended June 30, 2019 consisted primarily of $42.1 million net repayments of long-term debt, taxes paid on net share settlement of $1.6 million and dividend distributions to noncontrolling interests of $1.2 million.  These uses of cash were partially offset by inflows of $6.7 million related to stock option exercises and $5.3 million of net increases in lines of credit and short-term debt. Net cash and cash equivalents used in financing activities was $83.4 million for the six months ended June 30, 2018. Net cash and cash equivalents used in the six months ended June 30, 2018 consisted primarily of repayments of long-term debt, net of $82.5 million and taxes paid on net share settlement of $8.6 million, partially offset by proceeds from short-term line of credit of $3.4 million.

Use of Derivative Instruments and Hedging

We use interest rate swaps, foreign exchange forward contracts and cross currency swaps to provide a level of protection against interest rate risks and foreign exchange exposure.

Hedges of Interest Rate Risk

The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps, including interest rate collars, as part of its interest rate risk management strategy.  Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

-29-

Hedges of Foreign Currency Risk

We are exposed to fluctuations in various foreign currencies against our different functional currencies. We use foreign currency forward agreements to manage this exposure and to preserve the economic value of foreign currency denominated monetary assets and liabilities; these instruments are not designated for hedge accounting treatment in accordance with ASC 815.  The fair value of our foreign exchange hedges approximates zero.

Net Investment Hedges

During 2019, we used cross currency swaps to hedge our foreign exchange exposure related to our investment in our foreign subsidiaries.  These instruments were subject to market fluctuations due to changes in foreign exchange rates and at times may be in a loss position.  Market fluctuations were recorded to other comprehensive income/loss since these instruments are subject to hedge accounting. If these instruments are in a loss position at maturity, or if we decided to exit these instruments while they are in a loss position, we would have to make a cash payment in the amount of the loss position.  During the second quarter of 2019, we decided to exit our positions in cross currency swaps.  As a result of exiting this position we were required to make a cash payment of approximately $0.3 million.

Off-Balance Sheet Arrangements

We do not have any transactions, arrangements or other relationships with unconsolidated entities that will affect our liquidity or capital resources. We have no special purpose entities that provide off-balance sheet financing, liquidity or market or credit risk support, nor do we engage in leasing, swap agreements, or outsourcing of research and development services that could expose us to liability that is not reflected on the face of our financial statements.

Contractual Obligations

There have been no material changes in our Contractual Obligations as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018, filed with the SEC on February 21, 2019.  

Critical Accounting Policies

Our critical accounting policies are described in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, and in the notes to our consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC on February 21, 2019. Any new accounting policies or updates to existing accounting policies as a result of new accounting pronouncements have been discussed in the notes to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q in Note 1 – Nature of Operations, Basis of Presentation, Recently Issued Accounting Pronouncements and Updates to Accounting Policies and Estimates. The application of our critical accounting policies may require management to make judgments and estimates about the amounts reflected in the condensed consolidated financial statements. Management uses historical experience and all available information to make these estimates and judgments, and different amounts could be reported using different assumptions and estimates.

Recently Issued Accounting Pronouncements

Risk Factors

RISKS RELATED TO OUR BUSINESS

The success of our business depends on the strength of the global economy and the stability of the financial markets, and any weaknesses in these areas may have a material adverse effect on our net sales, operating results and financial condition.

During times of difficult market conditions, our fixed costs combined with lower net sales and lower profit margins may have a negative impact on our business, operating results and financial condition.

Downturns in the highly cyclical semiconductor industry or changes in end-market demand could adversely affect our operating results and financial condition.

The semiconductor business is highly competitive, and increased competition may harm our business, operating results and financial condition.

One of our external suppliers is also a related party. The loss of this supplier could harm our business, operating results and financial condition.

Delays in initiation of production at facilities due to implementing new production techniques or resolving problems associated with technical equipment malfunctions could adversely affect our manufacturing efficiencies, operating results and financial condition.

We are and will continue to be under continuous pressure from our customers and competitors to reduce the price of our products, which could adversely affect our growth and profit margins.

Our customers require our products to undergo a lengthy and expensive qualification process without any assurance of product sales and may demand to audit our operations from time to time.  A failure to qualify a product or a negative audit finding could adversely affect our net sales, operating results and financial condition.

Our customer orders are subject to cancellation or modification usually with no penalty. High volumes of order cancellation or reduction in quantities ordered could adversely affect our net sales, operating results and financial condition.

Production at our manufacturing facilities could be disrupted for a variety of reasons, including natural disasters and other extraordinary events, which could prevent us from producing enough of our products to maintain our sales and satisfy our customers’ demands and could adversely affect our operating results and financial condition.

-31-

New technologies could result in the development of new products by our competitors and a decrease in demand for our products, and we may not be able to develop new products to satisfy changes in demand, which would adversely affect our net sales, market share, operating results and financial condition.

We may be adversely affected by any disruption in our information technology systems, which could adversely affect our cash flows, operating results and financial condition.

We may be subject to claims of infringement of third-party intellectual property rights or demands that we license third-party technology, which could result in significant expense, reduction in our intellectual property rights and a negative impact on our business, operating results and financial condition.

We depend on third-party suppliers for timely deliveries of raw materials, manufacturing services, product and process development, parts and equipment, as well as finished products from other manufacturers, and our reputation with customers, operating results and financial condition could be adversely affected if we are unable to obtain adequate supplies in a timely manner.

If we do not succeed in continuing to vertically integrate our business, we will not realize the cost and other efficiencies we anticipate, which could adversely affect our ability to compete, our operating results and financial condition.

Part of our growth strategy involves identifying and acquiring companies. We may be unable to identify suitable acquisition candidates or consummate desired acquisitions and, if we do make any acquisitions, we may be unable to successfully integrate any acquired companies with our operations, which could adversely affect our business, operating results and financial condition.

We are subject to litigation risks, including securities class action litigation and intellectual property litigation, which may be costly to defend and the outcome of which is uncertain and could adversely affect our business and financial condition.

We are subject to many environmental laws and regulations that could result in significant expenses and could adversely affect our business, operating results and financial condition.

Our products, or products we purchase from third parties for resale, may be found to be defective and, as a result, warranty claims and product liability claims may be asserted against us and we may not have recourse against our suppliers, which may harm our business, reputation with our customers, operating results and financial condition.

We may fail to attract or retain the qualified technical, sales, marketing, finance and management/executive personnel required to operate our business successfully, which could adversely affect our business, operating results and financial condition.

We may not be able to achieve future growth, and any such growth may place a strain on our management and on our systems and resources, which could adversely affect our business, operating results and financial condition.

Obsolete inventories as a result of changes in demand for our products and change in life cycles of our products could adversely affect our business, operating results and financial condition.

If our direct sales customers do not design our products into their applications, our net sales may be adversely affected.

We are subject to interest rate risk that could have an adverse effect on our cost of working capital and interest expenses, which could adversely affect our business, operating results and financial condition.

Our hedging strategies may not be successful in mitigating our risks associated with interest rates or foreign exchange exposure or our counterparties might not perform as agreed.

We may have a significant amount of debt with various financial institutions worldwide. Any indebtedness could adversely affect our business, operating results, financial condition and our ability to meet payment obligations under such debt.

Restrictions in our credit facilities may limit our business and financial activities, including our ability to obtain additional capital in the future.

Our business benefits from certain Chinese government incentives. Expiration of, or changes to, these incentives could adversely affect our operating results and financial condition.

-32-

We operate a global business through numerous foreign subsidiaries, and there is a risk that tax authorities will challenge our transfer pricing methodologies or legal entity structures, which could adversely affect our operating results and financial condition.

The value of our benefit plan assets and liabilities is based on estimates and assumptions, which may prove inaccurate and the actual amount of expenses recorded in the consolidated financial statements could differ materially from the assumptions used.

Changes in actuarial assumptions for our defined benefit plan could increase the volatility of the plan’s asset value, require us to increase cash contributions to the plan and have a negative impact on our cash flows, operating results and financial condition.

Certain of our customers and suppliers require us to comply with their codes of conduct, which may include certain restrictions that may substantially increase our cost of doing business as well as have an adverse effect on our operating efficiencies, operating results and financial condition.

Compliance with government regulations and customer demands regarding the use of “conflict minerals” may result in increased costs and may have a negative impact on our business, operating results and financial condition.

There are risks associated with previous and future acquisitions. We may ultimately not be successful in overcoming these risks or any other problems encountered in connection with acquisitions.

If we fail to maintain an effective system of internal controls or discover material weaknesses in our internal control over financial reporting, we may not be able to report our financial results accurately or detect fraud, which could harm our business and the trading price of our Common Stock.

Terrorist attacks, or threats or occurrences of other terrorist activities, whether in the U.S. or internationally, may affect the markets in which our Common Stock trades, the markets in which we operate and our operating results and financial condition.

System security risks, data protection breaches, cyber-attacks and other related cybersecurity issues could disrupt our internal operations, and any such disruption could reduce our expected net sales, increase our expenses, damage our reputation and adversely affect our stock price.

RISKS RELATED TO OUR INTERNATIONAL OPERATIONS

Our international operations subject us to risks that could adversely affect our operations.

We have significant operations and assets in China, the U.K., Germany, Hong Kong and Taiwan and, as a result, will be subject to risks inherent in doing business in those jurisdictions, which may adversely affect our financial performance and operating results.

Significant uncertainties related to changes in governmental policies and participation in international trading partnerships or economic unions currently exist, and, depending upon how such uncertainties are resolved, the changes could have a material adverse effect on us.

Tariffs or other restrictions imposed by the United States Trade Representative may affect our operations in the U.S. and may disrupt our activities in the U.S. and may have an adverse impact on our profitability and results of operations.

The U.K.’s referendum to exit from the European Union (“E.U.”) will continue to have uncertain effects and could adversely impact our business, results of operations and financial condition.

A slowdown in the Chinese economy could limit the growth in demand for electronic devices containing our products, which would have a material adverse effect on our business, operating results and prospects.

Economic regulation in China could materially and adversely affect our business, operating results and prospects.

We could be adversely affected by violations of the United States’ Foreign Corrupt Practices Act, the U.K.’s Bribery Act 2010, China’s anti-corruption campaign and similar worldwide anti-bribery laws.

We are subject to foreign currency risk as a result of our international operations.

-33-

China is experiencing rapid social, political and economic change, which has increased labor costs and other related costs that could make doing business in China less advantageous than in prior years. Increased labor costs in China could adversely affect our business, operating results and financial condition.

We may not continue to receive preferential tax treatment in Asia, thereby increasing our income tax expense and reducing our net income.

The distribution of any earnings of certain foreign subsidiaries may be subject to foreign income taxes, thus reducing our net income.

RISKS RELATED TO OUR COMMON STOCK

Variations in our quarterly operating results may cause our stock price to be volatile.

We may enter into future acquisitions and take certain actions in connection with such acquisitions that could adversely affect the price of our Common Stock.

Our directors, executive officers and significant stockholders hold a substantial portion of our Common Stock, which may lead to conflicts with other stockholders over corporate transactions and other corporate matters.

We were formed in 1959, and our early corporate records are incomplete. As a result, we may have difficulty in assessing and defending against claims relating to rights to our Common Stock purporting to arise during periods for which our records are incomplete.

Non-cash tender offers, debt equity swaps or equity exchanges to consummate our business activities are likely to have the effect of diluting the ownership interest of existing stockholders, including qualified stockholders who receive shares of our Common Stock in such business activities.

Anti-takeover effects of certain provisions of Delaware law and our Certificate of Incorporation and Bylaws, may hinder a take-over attempt.

Section 203 of Delaware General Corporation Law may deter a take-over attempt.

Certificate of Incorporation and Bylaw Provisions may deter a take-over attempt.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

There have been no material changes to our market risks as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2018, filed with the SEC on February 21, 2019.

Item 4. Controls and Procedures.

Our Chief Executive Officer, Keh-Shew Lu, and Chief Financial Officer, Brett R. Whitmire, with the participation of our management, carried out an evaluation, as of June 30, 2019, of the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e).) Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer believe that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures are effective at the reasonable assurance level to ensure that information required to be included in this report is:

• recorded, processed, summarized and reported within the time period specified in the Commission’s rules and forms; and

• accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions on required disclosure.

Disclosure controls and procedures, no matter how well designed and implemented, can provide only reasonable assurance of achieving an entity’s disclosure objectives. The likelihood of achieving such objectives is affected by limitations inherent in disclosure controls and procedures. These include the fact that human judgment in decision-making can be faulty and that breakdowns in internal control can occur because of human failures such as simple errors, mistakes or intentional circumvention of the established processes.

Changes in Controls over Financial Reporting

There was no change in our internal control over financial reporting, known to our Chief Executive Officer or Chief Financial Officer, that occurred in the three months ended June 30, 2019, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

-35-

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

The Company is not a party to any pending litigation that we consider material.

From time to time, we are involved in various legal proceedings that arise in the normal course of business. While we intend to defend any lawsuit vigorously, we presently believe that the ultimate outcome of any pending legal proceeding will not have any material adverse effect on our financial position, cash flows or operating results. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which could impact our business and operating results for the period in which the ruling occurs or future periods.

Item 1A. Risk Factors.

Except as identified in the modified Risk Factor set out below, there have been no material changes to our risk factors from those disclosed in the "Risk Factors" section of our Annual Report on Form 10-K for the year ended December 31, 2018, filed with the Securities and Exchange Commission on February 21, 2019.

Tariffs or other restrictions imposed by the United States Trade Representative may affect our operations in the U.S., may disrupt our activities in the U.S., may have an adverse impact on our profitability and results of operations and may encourage the independent development in China of products and electronic components that will compete with ours or displace our products and components, resulting in an adverse impact on our Chinese business.

In May 2019, at the direction of the President, the United States increased the level of tariffs from 10 percent to 25 percent on approximately $200 billion worth of Chinese imports. The President also ordered the U.S. Trade Representative to begin the process of raising tariffs on essentially all remaining imports from China, which are valued at approximately $300 billion. These tariffs are in addition to the recently imposed new or higher tariffs on specified products imported from China in response to what the U.S. characterizes as unfair trade practices. China responded to the earlier increased tariffs by proposing new or higher tariffs on specified products imported from the United States.  Negotiations between the U.S. and China to resolve the issues that precipitated the impositions of these tariffs are reported to be ongoing, but the situation is dynamic and the timing and nature of any ultimate resolution is currently uncertain. In June 2019, President Trump and Chinese President Xi Jinping agreed that they did not plan more tariffs against each other’s countries, but on August 1, 2019, President Trump announced that on September 1, 2019, the U.S. would put an additional tariff of 10% on $300 billion of goods and products coming from China to the U.S.

Most of our products are manufactured in China and then a portion of those products are imported into the U.S. The impacts on us of the recently imposed and proposed tariffs are uncertain because of the dynamic nature of governmental actions and responses, as well as possible exemptions for certain products. If the U.S. and China are able to negotiate the issues to restore a mutually advantageous and fair trading regime, the increased tariffs could be eliminated, but given the uncertainties, there can be no assurance of whether, or when, this will be accomplished. We have taken actions, and may take additional steps, to mitigate those impacts and protect our competitive position in the marketplace.  If we determine to pass some or all of these new tariff burdens on to our customers, the result may be a degradation of our competitive position and a loss of customers that would adversely affect our operating performance. It is not clear at this time what the ultimate outcome of these tariff actions and our mitigation efforts will be, but given the importance of our Chinese operations and related sales, and the impacts of existing and possible future restrictions with regard to transactions with Chinese entities, it is very possible that our operating results and/or financial condition may be adversely affected.

In addition, China is stepping up efforts to design and manufacture semiconductors itself rather than buy from the U.S., amid fears that sanctions might cripple its high-tech industry. U.S. restrictions on exports to Chinese telecoms equipment makers have sharpened Beijing’s focus on semiconductor self-sufficiency. China’s ministry of finance announced tax breaks “to support the development of integrated circuit design and the software industry,” cancelling corporate taxes for some companies for two years. Although the outcome of these efforts is uncertain, the development of such capacity in China would likely have a material adverse effect on our profitability and results of operations.

In certain instances the disclosure schedules to such agreements or documents contain information that modifies, qualifies and creates exceptions to the representations, warranties and covenants. Moreover, some of the representations and warranties may not be complete or accurate as of a particular date because they are subject to a contractual standard of materiality that is different from those generally applicable to stockholders and/or were used for the purpose of allocating risk among the parties rather than establishing certain matters as facts.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Nature of Operations, Basis of Presentation, Recently Issued Accounting Pronouncements and Updates to Accounting Policies and Estimates

NOTE 1 – Nature of Operations, Basis of Presentation, Recently Issued Accounting Pronouncements and Updates to Accounting Policies and Estimates

Basis of Presentation

The condensed consolidated financial data at December 31, 2018 is derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018 filed with the Securities and Exchange Commission (“SEC”) on February 21, 2019 (“Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, operating results and cash flows in conformity with GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in our Form 10-K.  All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the operating results for the period presented have been included in the interim period. Operating results for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2019.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. As permitted under GAAP, interim accounting for certain expenses, including income taxes, are based on full year forecasts. For interim financial reporting purposes, income taxes are recorded based upon estimated annual effective income tax rates taking into consideration discrete items occurring in a quarter.

Dollar amounts and share amounts are presented in thousands, except per share amounts, unless otherwise noted. Certain prior year’s balances may have been reclassified to conform to the current financial statement presentation.

Recently Issued Accounting Pronouncements

The Financial Accounting Standards Board (“FASB”) issued the following Accounting Standards Updates (“ASU”) which could have potential impact on the Company’s financial statements:   

Recently Adopted Standards

ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”) – In February 2016, the FASB issued ASU 2016-02, which amends the accounting treatment for leases and requires, among other things, lessees to recognize a right-of-use (“ROU”) asset and lease liability for most lease arrangements. The amendments were effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company adopted ASU 2016-02 on January 1, 2019, using the modified retrospective transition approach, under which financial results reported in periods prior to 2018 are unchanged. We elected the following allowed practical expedients as permitted under the transition guidance within the new standard:

• Not record leases with an initial term of 12 months on the balance sheet;

• Not separate non-lease components of leases from the lease components; and

• Not reassess (1) the definition of a lease, (2) lease classification, and (3) initial direct costs for existing leases during transition.

Upon adoption of ASU 2016-02, the Company recorded ROU assets of $68.3 million, including land-use rights of $17.1 million previously recorded in other assets and $2.5 million previously recorded in property, plant and equipment and ROU liabilities of $50.4 million. For additional information related to the Company’s leases, see Note 10.    

ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting ("ASU 2018-07") - In June 2018, the FASB issued ASU 2018-07, which simplifies several aspects of the accounting for nonemployee share-based payment transactions resulting from expanding the scope of Topic 718, Compensation—Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 was effective for the Company on January 1, 2019. The adoption of this standard did not have a material effect on our condensed consolidated financial statements or disclosures.

ASU No. 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”) -In August 2017, the FASB issued ASU No. 2017-12 to better align hedge accounting with risk management strategies, and as a result, more hedging strategies will be eligible for hedge accounting. Public business entities will have until the end of the first quarter in which a hedge is designated to perform an initial assessment of a hedge’s effectiveness. After initial qualification, the new guidance permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test if the company can reasonably support an expectation of high effectiveness throughout the term of the hedge. An initial quantitative test to establish that the hedge relationship is highly effective is still required. The amendments are effective for fiscal years beginning after December 15, 2018, and the Company adopted the new standard January 1, 2019. The new standard had no impact on the Company’s financial statements.

On January 1, 2019, the Company adopted ASU No. 2018-16, “Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes”. The amendments in this ASU permit the use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under ASC 815, in addition to the currently permissible benchmark interest rates. This ASU provides the Company the ability to utilize the OIS rate based on SOFR as the benchmark interest rate on certain hedges of interest rate risk. The new standard had no impact on the Company’s financial statements.

Standards Effective in Future Years

The FASB has issued the following relevant standards, effective in future years, which are not expected to have a material impact on our consolidated condensed financial statements:

Standard No.	Standard Name	Standard Effective Date
2018-13	Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement	January 1, 2020
2018-14	Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans	January 1, 2020

In April 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, that clarifies and improves areas of guidance related to the recently issued standards on credit losses (ASU 2016-13), hedging (ASU 2017-12), and recognition and measurement of financial instruments (ASU 2016-01). The amendments generally have the same effective dates as their related standards. If already adopted, the amendments of ASU 2016-01 and ASU

2016-13 are effective for fiscal years beginning after December 15, 2019 and the amendments of ASU 2017-12 are effective as of the beginning of the Company’s next annual reporting period; early adoption is permitted. The Company is currently evaluating the impact this change will have on its consolidated financial statements and disclosures.    

All other issued and not yet effective accounting standards are not expected to be relevant to the Company.

Updates to Accounting Policies and Estimates

Leases

The Company determines if an arrangement is a lease at inception. ROU assets are included in Other assets in the Company’s condensed consolidated balance sheets. Current ROU liabilities are included in Accrued liabilities and other and long-term ROU liabilities are included in Other long-term liabilities, in our condensed consolidated balance sheets.

ROU assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. To determine the present value of the lease payments, we estimate our incremental borrowing rate based on information available at the lease commencement date.

The Company’s lease term includes options to extend the lease when it is reasonably certain that it will exercise that option. Leases with a term of 12 months or less are not recorded on the balance sheet. Our leases typically do not contain any residual value guarantees.  For real estate, we account for the lease and non-lease components as a single lease component.

Earnings Per Share [Abstract]

Earnings Per Share

NOTE 2 – Earnings per Share

Earnings per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted-average number of shares of Common Stock outstanding during the period. Diluted EPS is calculated similarly but includes potential dilution from the exercise of stock options and stock awards, except when the effect would be anti-dilutive.  During the three and six months ended June 30, 2019 and 2018 we paid no dividends on our Common Stock.

The table below sets forth the reconciliation between net income and the weighted average shares outstanding used for calculating basic and diluted EPS:

Goodwill and Intangible Assets

NOTE 4 – Goodwill and Intangible Assets

The table below sets forth the changes in goodwill:

Balance at December 31, 2018	$	132,437
Acquisitions:
Wafer fabrication facility in Greenock, Scotland (a)		931
Canyon investment (b)		1,443
ERIS investment in Yea-Shin (c)		4,320
Foreign currency translation adjustment		(359	)
Balance at June 30, 2019	$	138,772

The increase in goodwill is related to:

(a)  The Company’s acquisition accounting for the purchase of a wafer fabrication facility in Greenock, Scotland, (“GFAB”).  (See Note 13 for additional information).

(b)  The acquisition accounting for the Company’s investment of $3.4 million in Canyon Semiconductor.  This investment brings our ownership of Canyon to 51%.  During the second quarter of 2019, as a measurement period adjustment, we reduced the amount of goodwill approximately $1.1 million. This reduction in goodwill was related to finalization of the non-controlling interest value. The acquisition accounting is not final as deferred taxes are being finalized.  We expect the acquisition accounting to be finalized in the third quarter of 2019.   

(c)  The acquisition accounting related to Eris’ investment of approximately $6.4 million in Yea-Shin Technology Corporation.  During the second quarter of 2019, as a measurement period adjustment, we increased goodwill approximately $4.3 million, related to finalization of deferred taxes. The Company owns approximately 51% of Eris and Eris owns approximately 60% of Yea-Shin.

Diluted	$	(0.01	)	$	-		$	(0.02	)	$	0.01

The decrease in the effective tax rate for the three and six months ended June 30, 2019 when compared to the three and six months ended June 30, 2018, is primarily attributable to an increase in estimated full year global pretax book income and a net decrease in unfavorable U.S. permanent differences.         

Our undistributed foreign earnings continue to be indefinitely reinvested in foreign operations, with limited exceptions related to earnings of European and Asian subsidiaries.  Any future distributions of foreign earnings will not be subject to additional U.S. income tax, but may be subject to non-U.S. withholding taxes.

We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. We are no longer subject to U.S. federal income tax examinations by tax authorities for tax years before 2008, or for the 2010 and 2011 tax years. We are no longer subject to China income tax examinations by tax authorities for tax years before 2009. With respect to state and local jurisdictions and countries outside of the U.S. (other than China), with limited exceptions, the Company is no longer subject to income tax audits for years before 2013. Although the outcome of tax audits is always uncertain, the Company believes that adequate amounts of tax, interest and penalties, if any, have been provided for in the Company’s reserve for any adjustments that may result from currently pending tax audits. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in interest expense. As of June 30, 2019, the gross amount of unrecognized tax benefits was approximately $35.9   million. 

It is reasonably possible that the amount of the unrecognized benefit with respect to certain of the Company’s unrecognized tax positions will significantly increase or decrease within the next 12 months. At this time, an estimate of the range of the reasonably possible outcomes cannot be made.

Segment Reporting [Abstract]

Segment Information and Net Sales

NOTE 7 – Segment Information and Net Sales

Segment Reporting. For financial reporting purposes, we operate in a single segment, standard semiconductor products, through our various manufacturing and distribution facilities. We aggregate our products because the products are similar and have similar economic characteristics, use similar production processes and share the same customer type. Our primary operations include operations in Asia, North America and Europe.  During the three months ended June 30, 2019 and 2018, one customer, a broad-based global distributor that sells to thousands of different end users, accounted for 10% or $31.5 million and 10.9% or $33.3 million, respectively, of our net sales.  During the six months ended June 30, 2018, the same customer accounted for 10.7% or $61.7 million of our net sales. This customer did not account for 10% or greater of our outstanding accounts receivable at June 30, 2019 or 2018.  

The tables below set forth net sales based on the location of the subsidiary producing the net sale.

Disaggregation of Net sales. We disaggregate net sales from contracts with customers into direct sales and distribution sales (“Distributors”) and by geographic area. Direct sales customers consist of those customers using our product in their manufacturing process, and Distributors are those customers who resell our products to third parties. We sell our products to customers in multiple areas of the world including Asia, Europe, and North America. Across these regions, we sell products to end users in a variety of markets such as consumer electronics, computing, communications, industrial and automotive. Further, most of our contracts are fixed-price arrangements, and are short term in nature, ranging from days to several months.

The tables below set forth the amount of net sales by type (direct sales or Distributor) and the location of the customer based on the location where the products were shipped for the three and six months ended June 30, 2019 and 2018:

Commitments And Contingencies Disclosure [Abstract]

Commitments and Contingencies

NOTE 8 – Commitments and Contingencies

Purchase commitments – As of June 30, 2019, we had approximately $18.5 million in non-cancelable purchase contracts related to capital expenditures, primarily related to our manufacturing facilities in Asia.  As of June 30, 2019, we also had a commitment to purchase approximately $83.7 million of wafers to be used in our manufacturing process.  These wafer purchases will occur during 2019 and 2020.

Defined Benefit Plan - We have a contributory defined benefit plan that covers certain employees in the United Kingdom.  As of June 30, 2019, the unfunded liability for this defined benefit plan was approximately $27.7 million.  We are obligated to make annual contributions, each year through December 2029, of approximately GBP 2 million (approximately $2.6  million based on a GBP: USD exchange rate of 1.3:1).  The trustees are required to review the funding position every three years, and the most recent review was carried out in April 2019.  We anticipate receiving the outcome of the April 2019 review during the third quarter of 2019. The outcome of future reviews can result in a change in the amount of the payment.  

Contingencies – From time to time, we are involved in various legal proceedings that arise in the normal course of business. While we intend to defend any lawsuit vigorously, we presently believe that the ultimate outcome of any pending legal proceeding will not have any material adverse effect on our consolidated financial position, cash flows or operating results. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which could impact our business and operating results for the period in which the ruling occurs or future periods.  Based on information available, we evaluate the likelihood of potential outcomes of all pending disputes. We record an appropriate liability when the amount of any liability associated with a pending dispute is deemed probable and reasonably estimable. In addition, we do not accrue for estimated legal fees and other directly related costs as they are expensed as incurred.  The Company is not currently a party to any pending litigation that the Company considers material.

Basis of Presentation

Basis of Presentation

The condensed consolidated financial data at December 31, 2018 is derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018 filed with the Securities and Exchange Commission (“SEC”) on February 21, 2019 (“Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, operating results and cash flows in conformity with GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in our Form 10-K.  All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the operating results for the period presented have been included in the interim period. Operating results for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2019.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. As permitted under GAAP, interim accounting for certain expenses, including income taxes, are based on full year forecasts. For interim financial reporting purposes, income taxes are recorded based upon estimated annual effective income tax rates taking into consideration discrete items occurring in a quarter.

Dollar amounts and share amounts are presented in thousands, except per share amounts, unless otherwise noted. Certain prior year’s balances may have been reclassified to conform to the current financial statement presentation.

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements

The Financial Accounting Standards Board (“FASB”) issued the following Accounting Standards Updates (“ASU”) which could have potential impact on the Company’s financial statements:   

Recently Adopted Standards

ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”) – In February 2016, the FASB issued ASU 2016-02, which amends the accounting treatment for leases and requires, among other things, lessees to recognize a right-of-use (“ROU”) asset and lease liability for most lease arrangements. The amendments were effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company adopted ASU 2016-02 on January 1, 2019, using the modified retrospective transition approach, under which financial results reported in periods prior to 2018 are unchanged. We elected the following allowed practical expedients as permitted under the transition guidance within the new standard:

• Not record leases with an initial term of 12 months on the balance sheet;

• Not separate non-lease components of leases from the lease components; and

• Not reassess (1) the definition of a lease, (2) lease classification, and (3) initial direct costs for existing leases during transition.

Upon adoption of ASU 2016-02, the Company recorded ROU assets of $68.3 million, including land-use rights of $17.1 million previously recorded in other assets and $2.5 million previously recorded in property, plant and equipment and ROU liabilities of $50.4 million. For additional information related to the Company’s leases, see Note 10.    

ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting ("ASU 2018-07") - In June 2018, the FASB issued ASU 2018-07, which simplifies several aspects of the accounting for nonemployee share-based payment transactions resulting from expanding the scope of Topic 718, Compensation—Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 was effective for the Company on January 1, 2019. The adoption of this standard did not have a material effect on our condensed consolidated financial statements or disclosures.

ASU No. 2017-12 - Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”) -In August 2017, the FASB issued ASU No. 2017-12 to better align hedge accounting with risk management strategies, and as a result, more hedging strategies will be eligible for hedge accounting. Public business entities will have until the end of the first quarter in which a hedge is designated to perform an initial assessment of a hedge’s effectiveness. After initial qualification, the new guidance permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test if the company can reasonably support an expectation of high effectiveness throughout the term of the hedge. An initial quantitative test to establish that the hedge relationship is highly effective is still required. The amendments are effective for fiscal years beginning after December 15, 2018, and the Company adopted the new standard January 1, 2019. The new standard had no impact on the Company’s financial statements.

On January 1, 2019, the Company adopted ASU No. 2018-16, “Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes”. The amendments in this ASU permit the use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under ASC 815, in addition to the currently permissible benchmark interest rates. This ASU provides the Company the ability to utilize the OIS rate based on SOFR as the benchmark interest rate on certain hedges of interest rate risk. The new standard had no impact on the Company’s financial statements.

Standards Effective in Future Years

The FASB has issued the following relevant standards, effective in future years, which are not expected to have a material impact on our consolidated condensed financial statements:

Standard No.	Standard Name	Standard Effective Date
2018-13	Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement	January 1, 2020
2018-14	Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans	January 1, 2020

In April 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, that clarifies and improves areas of guidance related to the recently issued standards on credit losses (ASU 2016-13), hedging (ASU 2017-12), and recognition and measurement of financial instruments (ASU 2016-01). The amendments generally have the same effective dates as their related standards. If already adopted, the amendments of ASU 2016-01 and ASU

2016-13 are effective for fiscal years beginning after December 15, 2019 and the amendments of ASU 2017-12 are effective as of the beginning of the Company’s next annual reporting period; early adoption is permitted. The Company is currently evaluating the impact this change will have on its consolidated financial statements and disclosures.    

All other issued and not yet effective accounting standards are not expected to be relevant to the Company.

Updates to Accounting Policies and Estimates

Leases

The Company determines if an arrangement is a lease at inception. ROU assets are included in Other assets in the Company’s condensed consolidated balance sheets. Current ROU liabilities are included in Accrued liabilities and other and long-term ROU liabilities are included in Other long-term liabilities, in our condensed consolidated balance sheets.

ROU assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. To determine the present value of the lease payments, we estimate our incremental borrowing rate based on information available at the lease commencement date.

The Company’s lease term includes options to extend the lease when it is reasonably certain that it will exercise that option. Leases with a term of 12 months or less are not recorded on the balance sheet. Our leases typically do not contain any residual value guarantees.  For real estate, we account for the lease and non-lease components as a single lease component.

ERIS investment in Yea-Shin (c)		4,320
Foreign currency translation adjustment		(359	)
Balance at June 30, 2019	$	138,772

The increase in goodwill is related to:

(a)  The Company’s acquisition accounting for the purchase of a wafer fabrication facility in Greenock, Scotland, (“GFAB”).  (See Note 13 for additional information).

(b)  The acquisition accounting for the Company’s investment of $3.4 million in Canyon Semiconductor.  This investment brings our ownership of Canyon to 51%.  During the second quarter of 2019, as a measurement period adjustment, we reduced the amount of goodwill approximately $1.1 million. This reduction in goodwill was related to finalization of the non-controlling interest value. The acquisition accounting is not final as deferred taxes are being finalized.  We expect the acquisition accounting to be finalized in the third quarter of 2019.   

(c)  The acquisition accounting related to Eris’ investment of approximately $6.4 million in Yea-Shin Technology Corporation.  During the second quarter of 2019, as a measurement period adjustment, we increased goodwill approximately $4.3 million, related to finalization of deferred taxes. The Company owns approximately 51% of Eris and Eris owns approximately 60% of Yea-Shin.

[1] The Company’s acquisition accounting for the purchase of a wafer fabrication facility in Greenock, Scotland, (“GFAB”).  (See Note 13 for additional information).

[2] The acquisition accounting for the Company’s investment of $3.4 million in Canyon Semiconductor.  This investment brings our ownership of Canyon to 51%.  During the second quarter of 2019, as a measurement period adjustment, we reduced the amount of goodwill approximately $1.1 million. This reduction in goodwill was related to finalization of the non-controlling interest value. The acquisition accounting is not final as deferred taxes are being finalized.  We expect the acquisition accounting to be finalized in the third quarter of 2019.

[3] The acquisition accounting related to Eris’ investment of approximately $6.4 million in Yea-Shin Technology Corporation.  During the second quarter of 2019, as a measurement period adjustment, we increased goodwill approximately $4.3 million, related to finalization of deferred taxes. The Company owns approximately 51% of Eris and Eris owns approximately 60% of Yea-Shin.
