1. Summary of Significant Accounting Policies and Other Information

Nature of Operations

Littelfuse, Inc. and subsidiaries (the “Company”) is one of the world’s leading designer, manufacturer and supplier of circuit protection products, with expanding platforms in sensors and power control components and modules. In addition to circuit protection products and solutions, the Company offers electronic reed switches and sensors, automotive sensors for comfort and safety systems and a comprehensive line of highly reliable electromechanical and electronic switch and control devices for commercial and specialty vehicles, as well as protection relays and power distribution centers for the safe control and distribution of electricity. The Company has a network of global engineering centers and labs that develop new products and product enhancements, provides customer application support and test products for safety, reliability, and regulatory compliance. The Company’s products protect products in virtually every market that uses electrical energy, from consumer electronics to automobiles to industrial equipment.

Basis of Presentation

The Company’s accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain information and disclosures normally included in the consolidated balance sheet, statements of net income and comprehensive income and cash flows prepared in conformity with U.S. GAAP have been condensed or omitted as permitted by such rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. They have been prepared in accordance with accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016, which should be read in conjunction with the disclosures therein. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal, recurring nature. Operating results for interim periods are not necessarily indicative of annual operating results. Certain reclassifications of prior year amounts for Trade receivables, net and Prepaid expenses and other current assets were made to conform to the 2017 presentation.

Goodwill and Indefinite-Lived Intangible Assets

The Company annually tests goodwill and indefinite-lived intangible assets for impairment on the first day of its fiscal fourth quarter or at other dates if there is an event or change in circumstances that indicates the asset may be impaired. Management determines the fair value of each of its reporting units by using a discounted cash flow model (which includes forecasted five-year income statement and working capital projections, a market-based weighted average cost of capital and terminal values after five years) to estimate market value. In addition, the Company compares its derived enterprise value on a consolidated basis to the Company’s market capitalization as of its test date to ensure its derived value approximates the market value of the Company when taken as a whole.

Factors the Company considers important when performing the impairment tests, which could result in changes to its estimates, include underperformance relative to historical or projected future operating results and declines in acquisitions and trading multiples. Due to the diverse end user base and non-discretionary product demand, the Company does not believe its future operating results will vary significantly relative to its historical and projected future operating results. However, it is possible that impairment charges could be recognized for the Relays reporting unit if there are declines in profitability or projected future operating results and cash flows due to changes in volume, market pricing, cost, or the business environment. As of the most recent annual test conducted on October 2, 2016, the Company concluded the fair value of the Relays reporting unit exceeded its carrying value of invested capital and therefore, no potential goodwill impairment existed. As of the 2016 annual test date, the Relays reporting unit had $41.4 million of goodwill and intangible assets and the excess of fair value over the carrying value of invested capital was 15%. As of September 30, 2017, there were no events or circumstances that indicate the Relays intangible assets were impaired.

In the third quarter of 2016, due to continued declines in the potash market the Company conducted a goodwill impairment analysis of the Custom Products reporting unit and concluded that the reporting unit was impaired. The fair value of the unit was estimated using the expected present value of future cash flows over a seven year forecast period and appraisal of certain assets. This analysis required a write down of the reporting unit’s carrying value of $14.8 million. A goodwill impairment loss of $8.8 million and intangible assets impairments aggregating $6.0 million were recognized during the third quarter, including a $3.8 million reduction of the custom products trade names to a $0.7 million remaining value and a $2.2 million reduction of the reporting unit’s customer relationships to zero value.

Recently Adopted Accounting Standards

In July 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-11 – “Inventory (Topic 330): Simplifying the Measurement of Inventory,” which simplifies the measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value. The update is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company adopted the new standard on January 1, 2017. The adoption of the update did not have a material impact on the Company’s consolidated financial position and results of operations. As a result of the adoption of the update, inventories are stated at the lower of cost or net realizable value. Cost is principally determined using the first-in, first-out method. The Company maintains excess and obsolete allowances against inventory to reduce the carrying value to the expected net realizable value. These allowances are based upon a combination of factors including historical sales volume, market conditions, lower of cost or market analysis and expected realizable value of the inventory.

In March 2016, the FASB issued ASU No. 2016-09 – “Improvements to Employee Share-Based Payment Accounting,” which amends ASC 718, “Compensation – Stock Compensation.” The update simplifies several aspects of the accounting for employee share-based payment transactions, including accounting for income taxes, forfeitures, and statutory withholding requirements, as well as classification in the Condensed Consolidated Statements of Cash Flows. The update is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company adopted the new standard on January 1, 2017. As a result of the adoption, on a prospective basis, the Company recognized $0.1 million and $1.9 million of excess tax benefits from stock-based compensation as a discrete item in income tax expense for the three and nine months ended September 30, 2017, respectively. Historically, these amounts were recorded as additional paid-in capital. The Company also elected to apply the change prospectively to the Condensed Consolidated Statement of Cash Flows. As a result, on a prospective basis, share-based payments will be reported as operating activities in the Condensed Consolidated Statement of Cash Flows. The Company elected not to change its policy on accounting for forfeitures and will continue to estimate a requisite forfeiture rate. Additional amendments to the accounting for income taxes and minimum statutory withholding requirements had no impact on the results of operations.

Recently Issued Accounting Standards

In March 2017, the FASB issued ASU No. 2017-07 “Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost,” which changes the presentation of net periodic pension and post-retirement benefit cost (net benefit cost) within the Statement of Income. Under the current guidance, net benefit cost is reported as an employee cost within operating income. The amendment requires the bifurcation of net benefit cost, with the service cost component to be presented with other employee compensation costs in operating income while the other components will be reported separately outside of income from operations. ASU No. 2017-07 will be effective for the first quarter of 2018 and is required to be retrospectively adopted. Had this guidance been adopted as of January 1, 2017, operating income within the Condensed Consolidated Statements of Income for the three months and nine months ended September 30, 2017 would have not changed by a material amount.

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other” (Topic 350). This ASU modifies the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Because the update will eliminate Step 2 from the goodwill impairment test, it should reduce the cost and complexity of evaluating goodwill for impairment. This ASU is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2020, with early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company expects to adopt the new standard in 2017.

In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments-Recognition and Measurement of Financial Assets and Financial Liabilities” which addresses certain aspects of the recognition, measurement, presentation and disclosure of financial instruments. The ASU will require the Company to recognize any changes in the fair value of certain equity investments in net income. These changes are currently recognized in other comprehensive income ("OCI"). This guidance is effective for interim and fiscal years beginning after December 15, 2017.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (Topic 606) which supersedes the revenue recognition requirements in ASC 605, “Revenue Recognition.” This ASU provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. In August, 2015, the FASB issued ASU No. 2015-14, which postponed the effective date of ASU No. 2014-09 to fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted on the original effective date of fiscal years beginning after December 15, 2016. The Company is in the process of performing its assessment of the potential impact on its consolidated financial statements, and anticipates adopting this standard using the modified retrospective method. While the Company is currently assessing the impact of the new standard, the Company’s revenue is primarily generated from the sale of finished products to customers. Those sales predominantly contain a single delivery element and revenue is recognized at a single point in time when ownership, risks, and rewards transfer. These are largely un-affected by the new standard. The Company does not expect this new guidance to have a material impact on the amount of overall sales recognized; however, the timing of sales on certain projects may be affected. The Company has not yet quantified this potential impact.

Table of Contents

In February 2016, the FASB issued ASU No. 2016-02, "Leases" (Topic 842). This ASU requires lessees to recognize, on the balance sheet, assets and liabilities for the rights and obligations created by leases of greater than twelve months. The accounting by lessors will remain largely unchanged. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. Adoption will require a modified retrospective transition, however the Company plans to adopt the standard in the first quarter of 2019. The Company is currently evaluating the impact of ASU 2016-02.

2. Acquisitions

The Company accounts for acquisitions using the acquisition method in accordance with ASC 805, “Business Combinations,” in which assets acquired and liabilities assumed are recorded at fair value as of the date of acquisition. These acquisitions were recorded by allocating the cost of the acquisition to the assets acquired, including other intangible assets, based on their estimate fair values at the acquisition date. The excess of the cost over the net amounts assigned to the fair value of the assets acquired was recorded as goodwill. The goodwill associated with these acquisitions is primarily attributable to the synergies expected to arise as a result of these acquisitions. The operating results of the acquired business are included in the Company’s condensed consolidated financial statements from the date of the acquisition.

2017 Acquisitions

IXYS Corporation

On August 28, 2017, the Company announced that it had entered in a definitive agreement to acquire IXYS Corporation (“IXYS”), a global pioneer in the power semiconductor and integrated circuit markets with a focus on medium to high voltage power control semiconductors across the industrial, communications, consumer and medical markets. IXYS has a broad customer base, serving more than 3,500 customers through its direct salesforce and global distribution partners.

The Company will acquire all outstanding shares of common stock of IXYS in exchange for a combination of cash and shares of common stock of the Company. Each IXYS stockholder will be entitled to elect to receive, per IXYS share, either $23.00 in cash or 0.1265 of a share of Littelfuse common stock, subject to proration. In total, 50% of IXYS stock will be converted into the cash election option and the remaining will be converted into the stock election option. The equity value of the transaction at the announcement was approximately $750 million. The exchange ratio is fixed and will not be adjusted for changes in the market value of shares of Littelfuse or IXYS common stock. The market values of Littelfuse common stock and number of outstanding shares of IXYS common stock and equity-based awards will continue to fluctuate until the acquisition is completed. As a result, the final purchase price will differ from the initially announced purchase price, and that difference may be material.

The transaction is expected to close in the first calendar quarter of 2018 and is subject to the satisfaction of customary closing conditions, including regulatory approvals and approval by IXYS stockholders. The Company expects to finance the cash portion of the transaction consideration through a combination of existing cash and additional debt.

U.S. Sensor

On July 7, 2017, the Company acquired the assets of U.S. Sensor Corporation (“U.S. Sensor”) for $24.4 million. The Company funded the acquisition with available cash. The final purchase price is subject to adjustment for finalization of income tax gross up which is expected to be settled in the fourth quarter of 2017. The acquired business expands the Company’s existing sensor portfolio in several key electronics and industrial end markets. U.S. Sensor manufactures a variety of high quality negative temperature coefficient thermistors as well as thermistor probes and assemblies. Product lines also include thin film platinum resistance temperature detectors (“RTDs”) and RTD assemblies.

All U.S. Sensor goodwill, other assets and liabilities were recorded in the Electronics segment and reflected in the United States geographic area. The goodwill resulting from this acquisition consists largely of the Company’s expected future product sales and synergies from combining U.S. Sensor’s products and technology with the Company’s existing electronics product portfolio. Goodwill for the above acquisition is expected to be deductible for tax purposes.

As required by purchase accounting rules, the Company recorded a $1.6 million step-up of inventory to its fair value as of the acquisition date based on the preliminary valuation. The step-up was amortized as a non-cash charge to cost of goods sold during the third quarter of 2017, as the acquired inventory was sold, and reflected as other non-segment costs.

Monolith

In December 2015, the Company invested $3.5 million in the preferred stock of Monolith Semiconductor Inc. (“Monolith”), a U.S. start-up company developing silicon carbide technology, which represented approximately 12% of the common stock of Monolith on an as-converted basis. The Company accounted for its investment in Monolith under the cost method with any changes in value recorded in other comprehensive income. The value of the Monolith investment was $3.5 million at December 31, 2016.

On February 28, 2017, pursuant to a Securities Purchase Agreement between the Company and the stockholders of Monolith and conditioned on Monolith achieving a product development milestone and other provisions, the Company acquired approximately 62% of the outstanding common stock of Monolith for $15 million. The Securities Purchase Agreement includes provisions whereby the Company will acquire the remaining outstanding stock of Monolith (“non-controlling interest”) at a time or times based on Monolith meeting certain technical and sales targets. Consideration for the additional investment(s) will range from $1.0 million to $10 million and will be paid no later than June 30, 2019.

The additional investment resulted in the Company gaining control of Monolith and was accounted for as a step-acquisition with the fair value of the original investment immediately before the acquisition estimated to be approximately $3.5 million. As the fair value of the investment immediately prior to the transaction equaled the carrying value, there was no impact on the Company’s condensed consolidated statement of net income. As the Securities Purchase Agreement includes an obligation of the Company to mandatorily redeem the non-controlling interest for cash, the fair value of the non-controlling interest was recognized as a liability on the Company’s condensed consolidated balance sheet. Changes in the fair value of the non-controlling interest are recognized in the Company’s condensed consolidated statements of net income.

Commencing March 1, 2017, Monolith was reflected as a consolidated subsidiary within the Company’s condensed consolidated financial statements. Had the acquisition occurred as of January 1, 2017, the impact on the Company’s consolidated results of operations would not have been material.

Revolving Credit Facility / Term Loan

On October 13, 2017, the Company amended its existing Credit Agreement to increase the unsecured revolving credit facility from $575.0 million to $700.0 million and increase the unsecured term loan credit facility from $125.0 million to $200.0 million and to extend the expiration date from March 4, 2021 to October 13, 2022. The Credit Agreement also includes the option for the Company to increase the size of the revolving credit facility and the term loan facility by up to an additional $300.0 million, in the aggregate, subject to the satisfaction of certain conditions set forth in the Credit Agreement. Term loans may be made in up to two advances, the first advance occurring on October 13, 2017 and the second advance, in the aggregate amount not to exceed $75.0 million, to occur in the first quarter of 2018.

On March 4, 2016, the Company entered into a new five year credit agreement with a group of lenders for up to $700.0 million. The new credit agreement consists of an unsecured revolving credit facility of $575.0 million and an unsecured term loan credit facility of up to $125.0 million. In addition, the Company has the ability, from time to time, to increase the size of the revolving credit facility and the term loan facility by up to an additional $150.0 million, in the aggregate, in each case in minimum increments of $25.0 million, subject to certain conditions and the agreement of participating lenders. For the term loan credit facility, the Company is required to make quarterly principal payments of $1.6 million through March 31, 2018 and $3.1 million from June 30, 2018 through December 31, 2020 with the remaining balance due on March 4, 2021.

Outstanding borrowings under the credit agreement bear interest, at the Company’s option, at either LIBOR, fixed for interest periods of one, two, three or six month periods, plus 1.00% to 2.00%, or at the bank’s Base Rate, as defined, plus 0.00% to 1.00%, based upon the Company’s Consolidated Leverage Ratio, as defined. The Company is also required to pay commitment fees on unused portions of the credit agreement ranging from 0.15% to 0.30%, based on the Consolidated Leverage Ratio, as defined. The credit agreement includes representations, covenants and events of default that are customary for financing transactions of this nature. The effective interest rate on outstanding borrowings under the credit facility was 2.73% at September 30, 2017.

As of September 30, 2017, the Company had $0.1 million outstanding in letters of credit and had available $559.9 million of borrowing capacity under the revolving credit facility. At September 30, 2017, the Company was in compliance with all covenants under the credit agreement and expects to remain in compliance based on management’s estimates of operating and financial results for 2017 and the foreseeable future.

Senior Notes

On December 8, 2016, the Company entered into a Note Purchase Agreement, pursuant to which the Company issued and sold €212 million aggregate principal amount of senior notes in two series. The funding date for the Euro denominated senior notes occurred on December 8, 2016 for €117 million in aggregate amount of 1.14% Senior Notes, Series A, due December 8, 2023, and €95 million in aggregate amount of 1.83% Senior Notes, Series B due December 8, 2028 (together, the “Euro Senior Notes”). Interest on the Euro Senior Notes is payable semiannually on June 8 and December 8, commencing June 8, 2017.

On December 8, 2016, the Company entered into a Note Purchase Agreement, pursuant to which the Company issued and sold $125 million aggregate principal amount of senior notes in two series. On February 15, 2017, $25 million in aggregate principal amount of 3.03% Senior Notes, Series A, due February 15, 2022, and $100 million in aggregate principal amount of 3.74% Senior Notes, Series B, due February 15, 2027 (together, the “U.S. Senior Notes,” and together with the Euro Senior Notes, the “Senior Notes”) were funded. Interest on the U.S. Senior Notes will be payable semiannually on February 15 and August 15, commencing August 15, 2017.

The Senior Notes have not been registered under the Securities Act, or applicable state securities laws. The Senior Notes are general unsecured senior obligations and rank equal in right of payment with all existing and future unsecured unsubordinated indebtedness of the Company.

The Senior Notes are subject to certain customary covenants, including limitations on the Company’s ability, with certain exceptions, to engage in mergers, consolidations, asset sales and transactions with affiliates, to engage in any business that would substantially change the general business of the Company, and to incur liens. In addition, the Company is required to satisfy certain financial covenants and tests relating to, among other matters, interest coverage and leverage. At September 30, 2017, the Company was in compliance with all covenants under the revolving credit facility and the Senior Notes.

The Company may redeem the Senior Notes upon the satisfaction of certain conditions and the payment of a make-whole amount to noteholders, and are required to offer to repurchase the Senior Notes at par following certain events, including a change of control.

Entrusted Loan

During 2014, the Company entered into an entrusted loan arrangement (“Entrusted Loan”) of Chinese renminbi 110.0 million (approximately U.S. $17.9 million) between two of its China legal entities, Littelfuse Semiconductor (“Wuxi”) Company (the “lender”) and Suzhou Littelfuse OVS Ltd. (the “borrower”), utilizing Bank of America, N.A., Shanghai Branch as agent. Direct borrowing and lending between two commonly owned commercial entities was strictly forbidden at the time under China’s regulations requiring the use of a third party agent to enable loans between Chinese legal entities. As a result, the Entrusted Loan was reflected as both a long-term asset and long-term debt on the Company’s Condensed Consolidated Balance Sheets and was reflected in the investing and financing activities in its Condensed Consolidated Statements of Cash Flows. Interest expense and interest income are recorded between the lender and borrower with no net impact on the Company’s Condensed Consolidated Statements of Income since the amounts were offsetting. The loan interest rate per annum is 5.25%. The Entrusted Loan was used to finance the operation and working capital needs of the borrower and was scheduled to mature in November 2019. The balance of the Entrusted Loan was paid off as of September 30, 2017.

5. Fair Value of Assets and Liabilities

Applicable accounting literature establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Applicable accounting literature defines levels within the hierarchy based on the reliability of inputs as follows:

Level 1—Valuations based on unadjusted quoted prices for identical assets or liabilities in active markets;

Level 2—Valuations based upon quoted prices for similar instruments, prices for identical or similar instruments in markets that are not active, or model-derived valuations, all of whose significant inputs are observable, and

Level 3—Valuations based upon one or more significant unobservable inputs.

Following is a description of the valuation methodologies used for instruments measured at fair value and their classification in the valuation hierarchy.

Investments

Investments in equity securities listed on a national market or exchange are valued at the last sales price and are classified within Level 1 of the valuation hierarchy.

Table of Contents

There were no changes during the quarter ended September 30, 2017 to the Company’s valuation techniques used to measure asset and liability fair values on a recurring basis. As of September 30, 2017 and December 31, 2016, the Company did not hold any non-financial assets or liabilities that are required to be measured at fair value on a recurring basis.

The following table presents assets measured at fair value by classification within the fair value hierarchy as of September 30, 2017:

	Fair Value Measurements Using
(in thousands)	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Investment in Polytronics	$	10,582	$	—	$	—	$	10,582

The following table presents assets measured at fair value by classification within the fair value hierarchy as of December 31, 2016:

Investment in Polytronics	$	10,435	$	—	$	—	$	10,435

In addition to the methods and assumptions used for the financial instruments recorded at fair value as discussed above, the following methods and assumptions are used to estimate the fair value of other financial instruments that are not marked to market on a recurring basis. The Company’s other financial instruments include cash and cash equivalents, short-term investments, accounts receivable and its long-term debt. Due to their short-term maturity, the carrying amounts of cash and cash equivalents, short-term investments and accounts receivable approximate their fair values. The Company’s revolving and term loan debt facilities’ fair values approximate book value at September 30, 2017 and December 31, 2016, as the rates on these borrowings are variable in nature.

The carrying value and estimated fair values of the Company’s Euro Senior Notes, Series A and Series B and USD Senior Notes, Series A and Series B, as of September 30, 2017 and December 31, 2016 were as follows:

	September 30, 2017				December 31, 2016

8. Income Taxes

The effective tax rates for the three and nine months ended September 30, 2017 was 22.9% and 18.7%, respectively, compared to effective tax rates for the three and nine months ended October 1, 2016 of (1.2%) and 15.6%, respectively. The effective tax rates for the 2017 periods are lower than the U.S. statutory tax rate primarily due to income earned in lower tax jurisdictions, partially offset by a forecasted accrual for taxes on undistributed current year-earnings of certain non-US affiliates. The effective tax rate for the 2016 periods are lower than the U.S. statutory tax rate primarily due to income earned in lower tax jurisdictions and a one-time deduction with respect to the stock of one of the company’s affiliates partially offset by the impact of the impairment of goodwill for which no tax benefit was recorded.

10. Segment Information

The Company and its subsidiaries design, manufacture and sell components and modules for circuit protection, power control and sensing throughout the world. The Company reports its operations by the following segments: Electronics, Automotive, and Industrial. An operating segment is defined as a component of an enterprise that engages in business activities from which it may earn revenues and incur expenses, and about which separate financial information is regularly evaluated by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources. The CODM is the Company’s President and Chief Executive Officer (“CEO”). The CODM allocates resources to and assesses the performance of each operating segment using information about its revenue and operating income (loss) before interest and taxes, but does not evaluate the operating segments using discrete balance sheet information.

Sales, marketing, and research and development expenses are charged directly into each operating segment. Manufacturing, purchasing, logistics, customer service, finance, information technology, and human resources are shared functions that are allocated back to the three operating segments. The Company does not report inter-segment revenue because the operating segments do not record it. Certain expenses, determined by the CODM to be strategic in nature and not directly related to segments current results, are not allocated but identified as “Other”. Additionally, the Company does not allocate interest and other income, interest expense, or taxes to operating segments. These costs are not allocated to the segments, as management excludes such costs when assessing the performance of the segments. Although the CODM uses operating income (loss) to evaluate the segments, operating costs included in one segment may benefit other segments. Except as discussed above, the accounting policies for segment reporting are the same as for the Company as a whole.

Executive Summary

The Company had strong performance in the third quarter of 2017 compared to the third quarter of 2016. For the third quarter of 2017, the Company recognized net sales of $317.9 million compared to $280.3 million in the third quarter of 2016 representing an increase of $37.6 million, or 13.4%. The increase was primarily driven by the Electronics and Automotive segments. Net sales for Electronics increased $28.2 million, or 19.1%, due to strong growth across all the segment’s business units and geographic regions as well as the ON Portfolio and U.S. Sensor acquisitions in August 2016 and July 2017, respectively. Net sales for the Automotive segment increased $7.5 million, or 7.0% primarily due to growth in the passenger car fuse and commercial vehicle products businesses. Net sales in the Industrial segment increased $1.9 million or 7.4% due to growth in the fuse and relay businesses, partially offset by the divestiture of the JRS business in October 2016. The Company recognized net income of $42.8 million, or $1.87 per diluted share, in the third quarter of 2017 compared to net income of $30.8 million, or $1.35 per diluted share in the third quarter of 2016. The increase in net income reflects the impacts of the acquisitions on the current year results as well as a decrease in operating expenses driven by a $14.8 million goodwill and other intangible impairment charge recorded for the Custom Products reporting unit in the third quarter of 2016 and lower acquisition-related costs partially offset by higher income tax expense.

Net sales for the first nine months of 2017 were $916.7 million compared to $771.6 million in the first nine months of 2016. The increase of $145.1 million, or 18.8%, reflects increased net sales of $120.4 million, or 31.8%, in the Electronics segment and $28.5 million, or 9.2%, in the Automotive segment, partially offset by lower net sales of $3.8 million, or 4.5%, in the Industrial segment. The increase in net sales for the Electronics segment was due to strong growth across all the segment’s business units as well as the ON Portfolio, PolySwitch and U.S. Sensor acquisitions. The increase in net sales for the Automotive segment was primarily due to the impact of the prior year acquisitions of PolySwitch and Menber’s as well as volume growth in the passenger car and commercial vehicle businesses. The Company recognized net income of $130.3 million, or $5.69 per diluted share, in the first nine months of 2017 compared to net income of $77.2 million, or $3.41 per diluted share in the first nine months of 2016. Net income increased due to the impacts of the aforementioned acquisitions, higher gross profit driven largely driven by a favorable mix within the Electronics segment, a $14.8 million goodwill and other intangible assets impairment charge recorded in the Custom Products reporting unit in the third quarter of 2016 and lower acquisition-related costs partially offset by higher income tax expense.

Net cash provided by operating activities was $181.3 million for the nine months ended September 30, 2017 as compared to $100.0 million for the nine months ended October 1, 2016. The increase in net cash provided by operating activities reflected higher cash earnings, lower cash taxes and the timing of supplier payments partially offset by the timing of customer payments and increased inventory.

On August 28, 2017, the Company announced that it had entered into a definitive agreement to acquire IXYS, a global pioneer in the power semiconductor and integrated circuit markets with a focus on medium to high voltage power control semiconductors across the industrial, communications, consumer and medical markets. IXYS has a broad customer base, serving more than 3,500 customers through its direct salesforce and global distribution partners. IXYS reported revenues of $322 million in its fiscal year ended March 31, 2017.

The Company will acquire all of the outstanding shares of IXYS common stock in exchange for a combination of cash and shares of Company common stock. Each IXYS stockholder will be entitled to elect to receive, per IXYS share, either $23.00 in cash or 0.1265 of a share of Littelfuse common stock, subject to proration so that 50% of the shares of IXYS common stock outstanding immediately prior to the effective time of the merger of the subsidiary of the Company with and into IXYS will be converted into the cash election option and the remaining shares of IXYS common stock will be converted into the stock election option. The exchange ratio is fixed and will not be adjusted for changes in the market value of Littelfuse common stock or IXYS common stock and IXYS equity-based awards will continue to fluctuate until the acquisition is completed. As a result, the final purchase price will differ from the initially announced purchase price, and that difference may be material. The transaction is subject to customary closing conditions, including approval by IXYS stockholders.

Net Sales

Net sales increased $37.6 million, or 13.4%, for the third quarter of 2017 compared to the third quarter of 2016 with increases of $8.5 million and $2.9 million resulting from incremental net sales related to the ON Portfolio and U.S Sensor acquisitions, respectively. The remaining increase in net sales was driven by higher volume across all product lines in the Electronics segment and in the passenger car and commercial vehicle businesses within the Automotive segment.

Net sales for the first nine months of 2017 increased $145.0 million, or 18.8% compared to the first nine months of 2016 with $85.9 million resulting from the prior year acquisitions of PolySwitch, ON Portfolio, and Menber’s and $2.9 million from the current year U.S. Sensor acquisition. The remaining increase in net sales was primarily due to higher volume across all product lines in the Electronics segment and passenger car and commercial vehicle businesses within the Automotive segment partially offset by the divestiture of a core product line in the fourth quarter of 2016 and lower volume in the custom products operations within the Industrial segment.

Gross Profit

Gross profit was $133.7 million, or 42.0% of net sales, in the third quarter of 2017, compared to $113.8 million, or 40.6% of net sales in the third quarter of 2016. The increase in gross profit and gross margin reflects the incremental net sales and improved leverage in expenses and profits related to the prior year acquisitions.

Gross profit for the first nine months of 2017 was $379.9 million, or 41.4% of net sales compared to $298.8 million, or 38.7% of net sales for the first nine months of 2016. The increase in gross profit and gross margin reflects the incremental net sales and improved leverage in expenses and profits related to the prior year acquisitions primarily in the Electronics segment.

Operating Expenses

Total operating expenses were $75.0 million, or 23.6% of net sales, for the third quarter of 2017 compared to $86.2 million, or 30.8% of net sales, for the third quarter of 2016. The decrease in operating expenses of $11.2 million was primarily due to the $14.8 million goodwill and other intangible asset impairment charges related to the Custom Products reporting unit recognized in the third quarter of 2016 that was partially offset by increased amortization expense associated with recent acquisitions of $1.9 million and higher research and development expenses of $1.6 million. Selling, general and administrative expenses increased slightly by $0.2 million to $56.8 million, but decreased from 20.2% to 17.9% as a percentage of net sales, for the three months ended September 30, 2017 versus the three months ended October 1, 2016 primarily as a result of cost control initiatives and lower acquisition and integration charges.

Table of Contents

Total operating expenses for the first nine months of 2017 were $212.2 million, or 23.1% of net sales compared to $209.1 million, or 27.1% of net sales, for the first nine months of 2016. The increase in operating expenses of $3.1 million was primarily due to acquisitions, higher selling costs, higher research and development costs of $6.0 million and an increase of $5.0 million in amortization expense of intangible assets due to the acquisitions, partially offset by the $14.8 million of goodwill and other intangible asset impairment charges recognized in 2016 and lower acquisition-related expenses and integration costs of $9.2 million. Selling, general and administrative expenses increased by $6.9 million to $156.9 million, but decreased from 19.4% to 17.1% as a percentage of net sales for the nine months ended September 30, 2017 versus the same period in 2016 primarily as a result of lower acquisition-related expenses and integration costs of $9.2 million and cost control initiatives partially offset by the acquisitions.

Operating Income

Operating income was $58.6 million, an increase of $31.1 million or 113.0% for the third quarter of 2017 compared to $27.5 million for the third quarter of 2016. The increase in operating income was due to the acquisitions and higher Electronics volume and associated gross margin increases along with the $14.8 million goodwill and other intangible assets impairment charges recorded in the third quarter of 2016. Operating margins increased from 9.8% for the three months ended October 1, 2016 to 18.4% for the three months ended September 30, 2017. The 2016 goodwill and other intangible asset impairment charge improved margins by 5.3% while the remaining increase was due to higher volume, improvements in gross margin percentage, lower acquisition costs and operational efficiencies.

Operating income for the first nine months of 2017 was $167.7 million, an increase of $78.1 million or 87.1% compared to $89.7 million for the first nine months of 2016. The increase in operating income was the result of acquisitions and higher volume in the Electronics and Automotive segments. Operating margins increased from 11.6% to 18.3% for the nine months ended September 30, 2017 due to the acquisitions, improvement in gross margins, lower acquisition and integration related costs, the prior year goodwill and other intangible asset impairment charge and operational efficiencies.

Income Before Income Taxes

Income before income taxes was $55.5 million, or 17.5% of net sales, for the third quarter of 2017 compared to $30.4 million, or 10.9% of net sales, for the third quarter of 2016. Income before income taxes was impacted by higher operating income as described above, partially offset by an unfavorable increase in foreign exchange losses of $5.3 million primarily in the euro and Philippine peso against the U.S. dollar and higher interest expense of $0.9 million, reflecting increased borrowings.

Income before income taxes for the first nine months of 2017 was $160.3 million, or 17.5% of net sales compared to $91.5 million, or 11.9% of net sales, for the first nine months of 2016. Income before income taxes was impacted by an increase in operating income described above, partially offset by unfavorable changes in foreign exchange rates of $5.6 million primarily as a result of fluctuations in the euro and Philippine peso against the U.S. dollar and higher interest expense of $3.6 million due to higher borrowings.

Income Taxes

Income tax expense was $12.7 million, or an effective tax rate of 22.9%, for the third quarter of 2017 compared to income tax benefit of $0.4 million, or an effective tax rate of negative 1.2%, for the third quarter of 2016. The effective tax rates for both the third quarter of 2017 and the third quarter of 2016 are lower than the U.S. statutory tax rate primarily due to income earned in lower tax jurisdictions. The effective tax rate for the third quarter of 2017 reflected a forecasted accrual for taxes on undistributed current year-earnings of certain non-US affiliates. The effective tax rate for the third quarter of 2016 reflected a one-time deduction with respect to the stock of one of the company’s affiliates partially offset by the impact of the impairment of goodwill for which no tax benefit was recorded.

Income tax expense for the first nine months of 2017 was $30.0 million, or an effective tax rate of 18.7% compared to income tax expense of $14.3 million, or an effective tax rate of 15.6%, for the first nine months of 2016. The effective tax rates for both the first nine months of 2017 and the first nine months of 2016 are lower than the U.S. statutory tax rate primarily due to income earned in lower tax jurisdictions. The effective tax rate for the first nine months of 2017 reflected a forecasted accrual for taxes on undistributed current year-earnings of certain non-US affiliates. The effective tax rate for the first nine months of 2016 reflected the third quarter one-time deduction with respect to the stock of one of the company’s affiliates partially offset by the impact of the impairment of goodwill for which no tax benefit was recorded.

The Electronics segment net sales increased $120.4 million, or 31.8%, in the first nine months of 2017 compared to the first nine months of 2016 primarily due to the PolySwitch, ON Portfolio and U.S Sensor acquisitions, higher volume across all product lines that were partially offset by unfavorable foreign exchange impacts of $1.3 million.

Automotive Segment

The Automotive segment net sales increased $7.5 million, or 7.0%, in the third quarter of 2017 compared to the third quarter of 2016 primarily due to increased volume in the passenger car and commercial vehicle products businesses and favorable changes in foreign exchange rates of $1.7 million that were partially offset by a decrease in net sales from the automotive sensor business.

The Automotive segment net sales increased $28.5 million, or 9.2%, in the first nine months of 2017 compared to the first nine months of 2016 primarily due to the incremental net sales associated with the PolySwitch and Menber’s acquisitions, higher volume in passenger car and commercial vehicle products that were partially offset by unfavorable foreign exchange impacts of $1.7 million and lower volume in automotive sensor products.

Industrial Segment

The Industrial segment net sales increased $1.9 million, or 7.4%, in the third quarter of 2017 compared to the third quarter of 2016 primarily due to higher volume in the power fuse and relay operations partially offset by the divestiture of a non-core product line in the custom products business.

The Industrial segment net sales decreased $3.8 million, or 4.5%, in the first nine months of 2017 compared to the first nine months of 2016 primarily due to the divestiture of two non-core product lines, one in the fourth quarter of 2016 and the other in the first quarter of 2016, and lower volume in the custom products operations.

Liquidity and Capital Resources

The Company has historically supported its liquidity needs through cash flows from operations. Management expects that the Company’s (i) current level of cash, cash equivalents, and marketable securities, (ii) current and forecasted cash flows from operations, (iii) availability under existing funding arrangements, and (iv) access to capital in the capital markets will provide sufficient funds to support the Company’s operations, capital expenditures, investments, and debt obligations on both a short-term and long-term basis.

Revolving Credit Facility/Term Loan

On March 4, 2016, the Company entered into a new five-year credit agreement with a group of lenders for up to $700.0 million. The new credit agreement consists of an unsecured revolving credit facility of $575.0 million and an unsecured term loan credit facility of up to $125.0 million. In addition, the Company has the ability, from time to time, to increase the size of the revolving credit facility and the term loan facility by up to an additional $150.0 million, in the aggregate, in each case in minimum increments of $25.0 million, subject to certain conditions and the agreement of participating lenders. For the term loan credit facility, the Company is required to make quarterly principal payments of $1.6 million through March 31, 2018 and $3.1 million from June 30, 2018 through December 31, 2020 with the remaining balance due on March 4, 2021.

Outstanding borrowings under the credit agreement bear interest, at the Company’s option, at either LIBOR, fixed for interest periods of one, two, three or six month periods, plus 1.00% to 2.00%, or at the bank’s Base Rate, as defined, plus 0.00% to 1.00%, based upon the Company’s Consolidated Leverage Ratio, as defined. The Company is also required to pay commitment fees on unused portions of the credit agreement ranging from 0.15% to 0.30%, based on the Consolidated Leverage Ratio, as defined. The effective interest rate on outstanding borrowings under the credit facility was 2.73% at September 30, 2017. As of September 30, 2017, the Company had $0.1 million outstanding in letters of credit and had available $559.9 million of borrowing capacity under the revolving credit facility. Further information regarding the Company’s credit agreement is provided in Note 4, Debt, of the Notes to the Condensed Consolidated Financial Statements included in this Quarterly Report.

The following describes the Company’s cash flows for the nine months ended September 30, 2017 and October 1, 2016.

Cash Flow from Operating Activities

Operating cash inflows are largely attributable to sales of the Company’s products. Operating cash outflows are largely attributable to recurring expenditures for raw materials, labor, rent, interest, taxes and other operating activities.

Net cash provided by operating activities was $181.3 million for the first nine months of 2017, compared to $100.0 million during the nine months ended October 1, 2016. The increase in net cash provided by operating activities was primarily driven by higher cash earnings, lower cash taxes and the timing of supplier payments partially offset by the timing of customer payments and inventory.

Cash Flow from Investing Activities

Net cash used in investing activities was $79.2 million for the nine months ended September 30, 2017, compared to $498.4 million during the nine months ended October 1, 2016. Net cash used for acquisitions of $38.6 million in the nine months ended September 30, 2017 primarily related to the acquisition of a majority stake in Monolith Semiconductor ($14.2 million) and the acquisition of U.S. Sensor ($24.4 million). Net cash used for acquisitions of $468.6 million for the nine months ended October 1, 2016 primarily related to the acquisitions of Polyswitch ($344.5 million), the ON portfolio business ($104.0 million) and Menber’s ($19.2 million). Capital expenditures was $48.5 million, representing an increase of $14.0 million compared to 2016.

Cash Flow from Financing Activities

Net cash used in financing activities was $6.5 million for the nine months ended 2017 compared to net cash provided by financing activities of $262.4 million for the nine months ended 2016. The Company had $140.0 million of proceeds from the credit facility and senior notes payable and $117.2 million of payments on the term loan and credit facility in 2017 as compared to $492.0 million of proceeds from the credit facility and term loan and $216.6 million of payments on the term loan and credit facility. Additionally, dividends paid increased $3.0 million from $20.4 million in 2016 to $23.4 million for the nine months ended September 30, 2017.

Share Repurchase Program

The Company’s Board of Directors authorized the repurchase of up to 1,000,000 shares of the Company’s common stock under a program for the period May 1, 2017 to April 30, 2018 (“Share Repurchase Program”). The Company did not repurchase any shares of its common stock during the third quarter of 2017.

Off-Balance Sheet Arrangements

As of September 30, 2017, the Company did not have any off-balance sheet arrangements, as defined under SEC rules. Specifically, the Company was not liable for guarantees of indebtedness owed by third parties, the Company was not directly liable for the debt of any unconsolidated entity and the Company did not have any retained or contingent interest in assets. The Company does not participate in transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" (Topic 606) which supersedes the revenue recognition requirements in ASC 605, "Revenue Recognition." This ASU provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. In August, 2015, the FASB issued ASU No. 2015-14, which postponed the effective date of ASU No. 2014-09 to fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted on the original effective date of fiscal years beginning after December 15, 2016. The Company is in the process of performing its assessment of the potential impact on its consolidated financial statements and has not concluded on its adoption methodology. While the Company is currently assessing the impact of the new standard, the Company’s revenue is primarily generated from the sale of finished products to customers. Sales predominantly contain a single delivery element and revenue is recognized at a single point in time when ownership, risks, and rewards transfer. These are largely un-affected by the new standard. The Company does not expect this new guidance to have a material impact on the amount of overall sales recognized; however, the timing of sales on certain projects may be affected. The Company has not yet quantified this potential impact.
