Revenue Recognition
The Company recognizes revenue on product sales in the period in which the Company satisfies its performance obligation and control of the product is transferred to the customer. The Company’s sales arrangements with customers are predominately short term in nature and generally provide for transfer of control at the time of shipment as this is the point at which title and risk of loss of the product transfers to the customer. At the end of each period, for those shipments where title to the products and the risk of loss and rewards of ownership do not transfer until the product has been received by the customer, the Company adjusts revenues and cost of sales for the delay between the time that the products are shipped and when they are received by the customer. The amount of revenue recorded reflects the consideration to which the Company expects to be entitled in exchange for goods and may include adjustments for customer allowance, rebates and price adjustments. The Company’s distribution channels are primarily through direct sales and independent third-party distributors.
The Company elected the practical expedient under Accounting Standards Codification ("ASC") 340-40-25-4 to expense commissions when incurred as the amortization period of the commission asset the Company would have otherwise recognized is less than one year.
Revenue and Billing
The Company generally accepts orders from customers through receipt of purchase orders or electronic data interchange based on written sales agreements and purchasing contracts. Contract pricing and selling agreement terms are based on market factors, costs, and competition. Pricing is often negotiated as an adjustment (premium or discount) from the Company’s published price lists. The customer is invoiced when the Company’s products are shipped to them in accordance with the terms of the sales agreement. As the Company’s standard payment terms are less than one year, the Company elected the practical expedient under ASC 606-10-32-18 to not assess whether a contract has a significant financing component. The Company also elected the practical expedient provided in ASC 606-10-25-18B to treat all product shipping and handling activities as fulfillment activities, and therefore recognize the gross revenue associated with the contract, inclusive of any shipping and handling revenue. This is similar to the Company’s prior practice and therefore the effect of the new guidance is immaterial.
Ship and Debit Program
Some of the terms of the Company’s sales agreements and normal business conditions provide customers (distributors) the ability to receive price adjustments on products previously shipped and invoiced. This practice is common in the industry and is referred to as a “ship and debit” program. This program allows the distributor to debit the Company for the difference between the distributors’ contracted price and a lower price for specific transactions. Under certain circumstances (usually in a competitive situation or large volume opportunity), a distributor will request authorization for pricing allowances to reduce its price. When the Company approves such a reduction, the distributor is authorized to “debit” its account for the difference between the contracted price and the lower approved price. The Company establishes reserves for this program based on historic activity and actual authorizations for the debit and recognizes these debits as a reduction of revenue.

Return to Stock
The Company has a return to stock policy whereby certain customers, with prior authorization from Littelfuse management, can return previously purchased goods for full or partial credit. The Company establishes an estimated allowance for these returns based on historic activity. Sales revenue and cost of sales are reduced to anticipate estimated returns.
Volume Rebates
The Company offers volume based sales incentives to certain customers to encourage greater product sales. If customers achieve their specific quarterly or annual sales targets, they are entitled to rebates. The Company estimates the projected amount of rebates that will be achieved by the customer and recognizes this estimated cost as a reduction to revenue as products are sold.
Recently Adopted Accounting Standards
In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, "Leases" (Topic 842), ("ASC 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 requires using a modified retrospective transition with either 1) periods prior to the adoption date being recast or 2) a cumulative-effect adjustment recognized to the opening balance of retained earnings on the adoption date with prior periods not recast.
The Company adopted the standard on December 30, 2018 using alternative modified retrospective transition method provided in ASU No. 2018-11, "Leases (Topic 842): Target Improvements." Under this method, the Company recorded a cumulative-effect adjustment as of December 30, 2018 and did not record any retrospective adjustments to comparative periods to reflect the adoption of ASC 842. The new standard provides a number of optional practical expedients in transition. The Company has elected the ‘package of practical expedients’ which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The Company has not elected the use-of-hindsight. Adoption of ASC 842 resulted in the recognition of operating lease right-of-use assets ("ROU") net of deferred rent of $26.1 million and lease liabilities of $29.4 million, as of December 30, 2018 for operating leases on its Condensed Consolidated Balance Sheets, with no impact to its Condensed Consolidated Statements of Net Income and no impact on Condensed Consolidated Statements of Cash Flow. See Note 6, Lease Commitments, for further discussion.
In February 2018, the FASB issued ASU No. 2018-02 “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” which permits the reclassification of tax effects stranded in accumulated other comprehensive income to retained earnings as a result of the Tax Act. The standard also requires entities to disclose whether or not they elected to reclassify the tax effects related to the Tax Act as well as their policy for releasing income tax effects from accumulated other comprehensive income. The standard allows the option of applying either a retrospective adoption, meaning the standard is applied to all periods in which the effect of the Tax Act is recognized, or applying the amendments in the period of adoption, meaning an adjustment is made to shareholder’s equity as of the beginning of the reporting period. The Company adopted the new standard on December 30, 2018. The adoption of this guidance did not have a material effect on our Condensed Consolidated Financial Statements.
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. The operating results of the acquired business are included in the Company’s Consolidated Financial Statements from the date of the acquisition.
IXYS Corporation
On January 17, 2018, the Company acquired 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 sales force and global distribution partners. The acquisition of IXYS is expected to accelerate the Company’s growth

across the power control market driven by IXYS’s extensive power semiconductor portfolio and technology expertise. With IXYS, the Company will be able to diversify and expand its presence within industrial electronics markets, leveraging the strong IXYS industrial OEM customer base. The Company also expects to increase long-term penetration of its power semiconductor portfolio in automotive markets, expanding its global content per vehicle.
Upon completion of the acquisition, at IXYS stockholders’ election and subject to proration, each share of IXYS common stock, par value $0.01 per share, owned immediately prior to the effective time was canceled and extinguished and automatically converted into the right to receive: (i) $23.00 in cash (subject to applicable withholding tax), without interest (referred to as the cash consideration), or (ii) 0.1265 of a share of common stock, par value $0.01 per share, of Littelfuse (referred to as the stock consideration). IXYS stockholders received cash in lieu of any fractional shares of Littelfuse common stock that the IXYS stockholders would otherwise have been entitled to receive. Additionally, each outstanding option to purchase shares of IXYS common stock granted under an IXYS equity plan were assumed by Littelfuse and converted into an option to acquire (i) a number of shares of Littelfuse common stock equal to the number of shares of IXYS common stock subject to such option immediately prior to the effective time multiplied by 0.1265, rounded down to the nearest whole share, with (ii) an exercise price per share of Littelfuse common stock equal to the exercise price of such IXYS stock option immediately prior to the effective time divided by 0.1265, rounded up to the nearest whole cent.
Based on the $207.5 per share opening price of Littelfuse common stock on January 17, 2018, the consideration IXYS stockholders received in exchange of their IXYS common stock in the acquisition had a value of $814.8 million comprised of $380.6 million of cash and $434.2 million of Littelfuse stock. In addition to the consideration transferred related to IXYS common stock, the value of consideration transferred, and included in the purchase price, related to IXYS stock options that were converted to Littelfuse stock options, or cash settled, had a value of $41.7 million. As a result, total consideration was valued at $856.5 million.
The total purchase price of $856.5 million has been allocated to assets acquired and liabilities assumed, as of the completion of the acquisition, based on estimated fair values. The following table summarizes the purchase price allocation of the fair value of assets acquired and liabilities assumed in the IXYS acquisition:

(in thousands) | Purchase Price Allocation
Total purchase consideration: |
Cash, net of cash acquired | $ | 302,865 |
Cash settled stock options | 3,622 |
Littelfuse stock | 434,192 |
Converted stock options | 38,109 |
Total purchase consideration | $ | 778,788 |
Allocation of consideration to assets acquired and liabilities assumed: |
Current assets, net | $ | 155,930 |
Property, plant, and equipment | 77,442 |
Intangible assets | 212,720 |
Goodwill | 382,360 |
Other non-current assets | 28,706 |
Other non-current liabilities | (78,370 | )
| $ | 778,788 |

Approximately $49.1 million of net receivables was included in IXYS’s current assets. All IXYS goodwill, other assets and liabilities were recorded in the Electronics segment and primarily reflected in the Americas and European geographic areas. The goodwill resulting from this acquisition consists largely of the Company’s expected future product sales and synergies from combining IXYS’s products and technology with the Company’s existing electronics product portfolio. Goodwill resulting from the IXYS acquisition is not expected to be deductible for tax purposes.
Included in the Company’s Condensed Consolidated Statements of Net Income for the three and six months ended June 30, 2018 are net sales of approximately $100.2 million and $186.5 million, respectively, and a loss before income taxes of $13.9 million and $31.7 million, respectively, since the January 17, 2018 acquisition of IXYS. During the three and six months ended June 30,
11

Table of Contents
2018, the Company recognized a charge of $19.0 million and $36.9 million, respectively, for the amortization of the fair value inventory step-up. The step-up was a non-cash charge to cost of goods and reflected as other non-segment costs. The Company recognized approximately $1.6 million and $7.5 million of stock compensation expense related to IXYS stock options converted to Littelfuse stock options during the three and six months ended June 30, 2018, of which $4.5 million was recognized immediately as it related to prior services periods.
During the three and six months ended June 30, 2018, the Company incurred approximately $0.8 million and $11.0 million, respectively, of legal and professional fees related to this acquisition which were primarily recognized as selling, general, and administrative expenses. These costs were reflected as other non-segment costs.
Pro Forma Results
The following table summarizes, on a pro forma basis, the combined results of operations of the Company and IXYS as though the acquisition had occurred as of January 1, 2017. The pro forma amounts presented are not necessarily indicative of either the actual consolidated results had the IXYS acquisition occurred as of January 1, 2017 or of future consolidated operating results.

The Order backlog has a useful life of twelve months and was fully amortized in the fiscal 2017 pro forma results.

(b) | The transaction cost adjustments reflect the reversal of certain bank and attorney fees from the six months ended June 30, 2018 and recognition of those fees during the six months ended July 1, 2017.

(c) | The amortization of inventory step-up adjustment reflects the reversal of the amount recognized during the three and six months ended June 30, 2018 and recognition of those costs during the three and six months ended July 1, 2017. The inventory step-up was amortized over five months as the inventory was sold.

(d) | The stock compensation adjustment reflects the reversal of the portion of stock compensation for IXYS stock options that were converted to Littelfuse stock options and expensed immediately during the six months ended June 30, 2018.

Options to extend the lease are included in the lease term when it is reasonably certain the Company will exercise the option. The Company also has production equipment, office equipment and vehicles under operating leases. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option that is reasonably certain of exercise. Certain leases include rental payments adjusted periodically for inflation. The lease agreements do not contain any material residual value guarantee or material restrictive covenants.
The Company does not have a published credit rating because it has no publicly traded debt; therefore, the Company is generating its incremental borrowing rate (IBR), using a synthetic credit rating model that compares its credit quality to other rated companies based on certain financial metrics and ratios. The reference rate will be based on the yield curve of companies with similar credit quality based on the metrics and adjusted for currency in regions where we have significant operations.
All leases with an initial term of 12 months or less that do not include an option to extend or purchase the underlying asset that the Company is reasonably certain to exercise (“short-term leases”) are not recorded on the Condensed Consolidated Balance Sheet. Short-term lease expenses are recognized on a straight-line basis over the lease term.

10. Fair Value of Assets and Liabilities
For assets and liabilities measured at fair value on a recurring and nonrecurring basis, a three-level hierarchy of measurements based upon observable and unobservable inputs is used to arrive at fair value. Observable inputs are developed based on market data obtained from independent sources, while unobservable inputs reflect the Company’s assumptions about valuation based on the best information available in the circumstances. Depending on the inputs, the Company classifies each fair value measurement 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 in Equity Securities
Investments in equity securities listed on a national market or exchange are valued at the last sales price and classified within Level 1 of the valuation hierarchy and recorded in investments and other assets.
The Company has certain convertible debt and convertible preferred stock investments that are accounted for under the cost method reflected in other assets in the Condensed Consolidated Balance Sheets. During the six months ended June 29, 2019, the Company recorded impairment charges of $2.8 million in Other expense (income), net in the Condensed Consolidated Statements of Net Income to adjust these certain investments to their estimated fair value of $1.2 million. The fair value of these investments are measured on a nonrecurring basis and determined to be Level 3 under the fair value hierarchy. The Company's accounting and finance management determines the valuation policies and procedures for Level 3 fair value measurements and is responsible for the development and determination of unobservable inputs.
Mutual Funds
The Company has a non-qualified Supplemental Retirement and Savings Plan which provides additional retirement benefits for certain management employees and named executive officers by allowing participants to defer a portion of their annual compensation. The Company maintains accounts for participants through which participants make investment elections. The marketable securities are classified as Level 1 under the fair value hierarchy as they are maintained in mutual funds with readily determinable fair value and recorded in other assets.
There were no changes during the quarter ended June 29, 2019 to the Company’s valuation techniques used to measure asset and liability fair values on a recurring basis. As of June 29, 2019 and December 29, 2018, 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 June 29, 2019:

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 June 29, 2019 and December 29, 2018, 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 June 29, 2019 and December 29, 2018 were as follows:

16. 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.

• | Electronics Segment: Consists of one of the broadest product offerings in the industry, including fuses and fuse accessories, positive temperature coefficient (“PTC”) resettable fuses, polymer electrostatic discharge (“ESD”) suppressors, varistors, reed switch based magnetic sensing, gas discharge tubes; semiconductor and power semiconductor products such as discrete transient voltage suppressor (“TVS”) diodes, TVS diode arrays, protection and switching thyristors, silicon carbide, metal-oxide-semiconductor field-effect transistors (“MOSFETs”) and silicon carbide diodes; and insulated gate bipolar transistors (“IGBT”) technologies.

Executive Summary
For the second quarter of 2019, the Company recognized net sales of $397.9 million compared to $459.2 million in the second quarter of 2018 representing a decrease of $61.3 million, or 13.4%. The decrease was primarily driven by lower volume in Electronics and Automotive segments and $7.9 million or 1.7% of unfavorable changes in foreign exchange rates. The Company recognized net income of $43.8 million, or $1.75 per diluted share, in the second quarter of 2019 compared to net income of $42.3 million, or $1.67 per diluted share in the second quarter of 2018. The increase in net income reflects lower non-segment charges compared to prior year primarily due to the IXYS acquisition, partially offset by lower operating income across all segments and foreign exchange losses.
The Company continues to take actions to improve its cost structure and drive the synergies from the integration of IXYS. The Company expects to realize cost savings from the restructuring activities taken during 2019 including the reorganization of certain manufacturing, selling and administrative functions across all segments. For the three and six months ended June 29, 2019, the Company recorded total restructuring charges of $5.7 million and $8.4 million respectively, for employee termination costs and other restructuring charges, which included $1.7 million of restructuring costs associated with the closure of a European manufacturing facility in the automotive sensors business within the Automotive segment.
Net cash provided by operating activities was $80.1 million for the six months ended June 29, 2019 as compared to $140.9 million for the six months ended June 30, 2018. The decrease in net cash provided by operating activities reflected lower earnings and higher working capital levels primarily due to the timing of supplier payments.
During the three and six months ended June 29, 2019, the Company repurchased 188,214 and 268,130 shares of its common stock totaling $32.0 million and $45.5 million. Since September 30, 2018, the Company has repurchased 660,102 shares of its common stock at an average price of $171.81 totaling $113.4 million.
Results of Operations
The following table summarizes the Company’s condensed consolidated results of operations for the periods presented. The second quarter of 2019 includes $7.2 million ($12.2 million year-to-date) of non-segment charges, of which $5.7 million ($8.4 million year-to-date) of restructuring charges are primarily related to employee termination costs and $1.5 million ($3.8 million year-to-date) of acquisition related and integration charges are primarily related to the IXYS acquisition.
The second quarter of 2018 includes approximately $26.8 million ($65.4 million year-to-date) of charges primarily related to the IXYS acquisition, which include $19.0 million ($36.9 million year-to-date) of purchase accounting inventory step-up charges, $2.0 million ($13.6 million year-to-date) in acquisition-related and integration costs primarily related to legal, accounting and other expenses, $3.1 million ($5.6 million year-to-date)in backlog amortization costs, $2.7 million of employee termination costs and other restructuring charges, and $4.5 million year-to-date stock compensation expense recognized immediately upon close for converted IXYS options related to prior service periods and $2.1 million year-to-date change in control expense related to IXYS. In addition, there were $0.5 million ($1.2 million year-to-date)of employee termination costs, other restructuring, impairment charges of $1.1 million associated with the exit of the Custom business in the second quarter, and $0.3 million ($0.5 million year-to-date)of acquisition-related expenses for other contemplated acquisitions.
