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.
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, electronic distributor inventory levels and actual authorizations for the debit and recognizes these debits as a reduction of revenue.

Table of Contents
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 June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments." The standard modifies the measurement approach for credit losses on financial instruments, including trade receivables, from an incurred loss method to a current expected credit loss method ("CECL"). The standard requires the measurement of expected credit losses to be based on relevant information, including historical experiences, current conditions and a forecast that is supportable. The Company adopted the new standard on December 29, 2019. The adoption of the standard did not have a material effect on our Condensed Consolidated Financial Statements.
In August 2018, the FASB issued ASU No. 2018-13 "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirement for Fair Value Measurement." ASU 2018-13 modifies the disclosure requirements in Topic 820: "Fair Value Measurement," based on the FASB Concepts Statement, "Conceptual Framework for Financial Reporting - Chapter 8: Notes to Financial Statements," including consideration of costs and benefits. The new standard removes certain disclosures, modifies other disclosures and adds additional disclosures related to fair value measurement. The Company adopted the new standard on December 29, 2019. The adoption of ASU 2018-13 did not have a material impact on our Condensed Consolidated Financial Statements.
In August 2018, the FASB issued ASU No. 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic: 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force)." ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The Company adopted the new standard on December 29, 2019. The adoption of ASU 2018-15 did not have a material impact on our Condensed Consolidated Financial Statements.
In March 2020, the FASB issued ASU 2020-04 Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This ASU provides optional expedient and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The objective of this is to provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting due to the cessation of the London Interbank Offered Rate (LIBOR). The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company does not expect a material effect from the adoption of this guidance on its Condensed Consolidated Financial Statements.

As of December 28, 2019 |  | $ | 650,796 |  |  | $ | 131,321 |  |  | $ | 38,472 |  |  | $ | 820,589 |

The Company tests its goodwill annually for impairment on the first day of its fiscal fourth quarter, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. During the second quarter of 2020, the Company recorded a non-cash charge of $33.8 million to recognize the impairment of goodwill in the automotive sensors reporting unit within the Automotive segment. The goo dwill impairment charge was due to reductions in the estimated fair value for the automotive sensors reporting unit based on lower expectations for future revenue, profitability and cash flows as compared to the expectations of the 2019 annual goodwill impairment test. These lower future expectations were driven by projected extended declines in end market demand due to the COVID-19 pandemic. In addition, during the second quarter of 2020, certain customers notified the Company of their decision to delay future programs along with a customer canceling their existing program. The goodwill impairment charge was determined using Level 3 inputs, including discounted cash flow analysis and comparable marketplace fair value data. As of September 26, 2020, the automotive sensors reporting unit had $9.4 million of remaining goodwill.

Revolving Credit Facility / Term Loan
On March 4, 2016, the Company entered into a five-year credit agreement (“Credit Agreement”) with a group of lenders for up to $700.0 million. The Credit Agreement consisted of an unsecured revolving credit facility (“Revolving Credit Facility”) of $575.0 million and an unsecured term loan credit facility (“Term Loan”) of up to $125.0 million. In addition, the Company had the ability, from time to time, to increase the size of the Revolving Credit Facility and the Term Loan 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.
On October 13, 2017, the Company amended the Credit Agreement to increase the Revolving Credit Facility from $575.0 million to $700.0 million and increase the Term Loan from $125.0 million to $200.0 million and to extend the expiration date from March 4, 2021 to October 13, 2022.

For the Term Loan, the Company was required to make quarterly principal payments of 1.25% of the original term loan ($2.5 million quarterly) through maturity, with the remaining balance due on October 13, 2022. The Company paid $5.0 million of principal payments on the term loan before the Company amended the Credit Agreement on April 3, 2020 as discussed below.
On March 25, 2020, the company borrowed $100.0 million from the revolving credit facility to preserve financial flexibility and enhance liquidity, given the increasing levels of uncertainty related to coronavirus disease 2019 ("COVID-19").
On April 3, 2020, the Company amended the Credit Agreement to effect certain changes, including, among others: (i) eliminating the $200.0 million unsecured term loan credit facility, the remaining outstanding balance ($140.0 million) of which was repaid in full on April 3, 2020 through the revolving credit facility; (ii) making certain financial and non-financial covenants less restrictive on the Company; (iii) modifying performance-based interest rate margins and undrawn fees; and (iv) extending the maturity date to April 3, 2025. The amended Credit Agreement also allows the Company to increase the size of the revolving credit facility or enter into one or more tranches of term loans if there is no event of default and the Company is in compliance with certain financial covenants. The Company made payments of $60.0 million on the amended revolving credit facility during the three months ended September 26, 2020. The balance under the facility was $180.0 million as of September 26, 2020.

The Company was also required to pay commitment fees on unused portions of the credit agreement ranging from 0.125% to 0.20%, based on the Consolidated Leverage Ratio, as defined in the agreement. The amended Credit Agreement included 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 1.90% at September 26, 2020.
As of September 26, 2020, the Company had no amount outstanding in letters of credit and had available $245.1 million of borrowing capacity under the Revolving Credit Facility based on financial covenants.

8. 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.
Cash Equivalents
Cash equivalents primarily consist of money market funds, which are held with an institution with sound credit rating and are highly liquid. The Company classified cash equivalents as Level 1 and are valued at cost which approximates fair value.
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 three months ended September 26, 2020, the Company recorded impairment charges of $0.1 million and during the nine months ended September 28, 2019, the Company recorded impairment charges of $2.8 million in Other income, net in the Condensed Consolidated Statements of Net Income to adjust these certain investments to their estimated fair value. As of September 26, 2020 and December 28, 2019, the balances of these investments were $0.5 million and $0.4 million, respectively. The fair value of these investments are measured on a nonrecurring basis using Level 3 inputs 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.

Table of Contents
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 September 26, 2020 to the Company’s valuation techniques used to measure asset and liability fair values on a recurring basis. On October 30, 2019, the Company entered a foreign currency exchange forward contract to mitigate the currency fluctuation risk between the Chinese renminbi and U.S. dollar. The foreign currency contract was not designated as a hedge instrument and was marked to market on a monthly basis. The notional value of the forward contracts at December 28, 2019 was $16.0 million and expired on May 5, 2020. On March 23, 2020, the Company unwound the foreign currency exchange forward contract entered on October 30, 2019 and recognized a gain of $0.2 million within Other income, net during the nine months ended September 26, 2020. The fair value of the foreign currency forward contract was valued using market exchange rates and classified as a Level 2 input under the fair value hierarchy.
As of September 26, 2020 and December 28, 2019, 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 26, 2020:

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 26, 2020 and December 28, 2019, 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 26, 2020 and December 28, 2019 were as follows:

For three and nine months ended September 26, 2020, the pre-tax amounts recognized in other comprehensive income (loss) as components of net periodic benefit costs for these plans were $0.2 million and $0.5 million.
On April 7, 2020, the Company entered into a definitive agreement to purchase a group annuity contract, under which an insurance company will be required to pay and administer pension payments to certain of the Company’s U.K. pension plan participants, or their designated beneficiaries, who have been receiving pension payments. The purchase of this group annuity contract will reduce the Company’s outstanding pension benefit obligation by approximately $36 million, representing approximately 30% of the total obligations of the Company’s qualified pension plans, and will be funded with pension plan assets and additional cash on hand. In connection with this transaction, the Company will record a one-time non-cash settlement charge in the second half of 2021 currently estimated between $18 million and $22 million, reflecting the accelerated recognition of unamortized actuarial losses in the plan. The actual settlement charge could differ from this estimate due to final data and plan wind-up expenses. Due to the signing of the group annuity contract being a significant change in the U.K. pension plan, the liabilities of the plan were remeasured as of April 6, 2020 resulting in an increase of $13.4 million (£10.9 million) to both the net pension liability and unamortized actuarial loss within other comprehensive income (loss) during the second quarter. Additionally, the Company made a cash contribution of $10.4 million (£8.4 million) under this agreement during the second quarter.

11. Income Taxes
The effective tax rate for the three and nine months ended September 26, 2020 was 17.9% and 23.1% respectively, compared to the effective tax rate for the three and nine months ended September 28, 2019 of 13.9% and 17.7%. The effective tax rates for the 2020 periods are higher than the effective tax rates for the comparable 2019 periods, primarily due to the impact of the goodwill impairment charge of $33.8 million that was recorded in the second quarter of 2020, the substantial majority of which did not result in a tax benefit in the annual estimated effective tax rate, as well as a reduction in the forecasted income earned in lower tax jurisdictions in 2020 driven by the uncertainty resulting from the impact of COVID-19.
The effective tax rate for the first nine months of 2020 is higher than the applicable U.S. statutory tax rate primarily due to the impact of the goodwill impairment charge of $33.8 million that was recorded in the second quarter of 2020, the substantial majority of which did not result in a tax benefit in the annual estimated effective tax rate, as well as the forecasted impact of non-U.S. losses and expenses with no tax benefit and the U.S. global intangible low-taxed income tax provisions (in the 2019 comparable period the impact of these items was more than offset by the impact of income earned in lower tax jurisdictions), offset in part by the impact of income earned in lower tax jurisdictions.

14. 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. 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 products such as discrete transient voltage suppressor (“TVS”) diodes, TVS diode arrays, protection and switching thyristors, metal-oxide-semiconductor field effect transistors (“MOSFETs”) and silicon carbide diodes; and insulated gate bipolar transistors (“IGBT”) technologies. The segment covers a broad range of end markets, including industrial and
23

Table of Contents
automotive electronics, electric vehicle and related infrastructure, data and telecommunications, medical devices, alternative energy, consumer electronics and white goods.
•Automotive Segment: Consists of a wide range of circuit protection, power control and sensing technologies for global original equipment manufacturers (“OEMs”), Tier-I suppliers and parts distributors in passenger car, heavy duty truck, off-road vehicles, material handling, agricultural, construction and other commercial vehicle end markets. Passenger car fuse products include fuses and fuse accessories for internal combustion engine vehicles and hybrid and electric vehicles including blade fuses, battery cable protectors, resettable fuses, high-current fuses, and high-voltage fuses. Commercial vehicle products include fuses, switches, relays, and power distribution modules for the commercial vehicle industry. Automotive sensor products include a wide range of automotive and commercial vehicle products designed to monitor the passenger compartment occupants, safety and environment as well as the vehicle’s powertrain.

Executive Summary
For the third quarter of 2020, the Company recognized net sales of $391.6 million compared to $362.0 million in the third quarter of 2019 representing an increase of $29.6 million, or 8.2%. The increase was primarily driven by higher volume in Electronics segment, and $4.4 million or 1.2% of favorable changes in foreign exchange rates. The Company recognized net income of $55.4 million, or $2.25 per diluted share, in the third quarter of 2020 compared to net income of $35.6 million, or $1.44 per diluted share in the third quarter of 2019. The increase in net income reflects higher operating income in the Electronics and Automotive segments, higher foreign exchange gains and lower acquisition-related and integration charges.
The Company continues to take actions to improve its cost structure. The Company expects to realize cost savings from the restructuring activities taken during 2019 and 2020, including the reorganization of certain research and development, selling and administrative functions across all segments. The Company is also in process of several restructuring activities across its manufacturing and supply chain footprint, including the consolidation of a manufacturing facility within the Industrial Segment, which is expected to be completed in the first half of 2021.
Net cash provided by operating activities was $164.3 million for the nine months ended September 26, 2020 as compared to $160.9 million for the nine months ended September 28, 2019. The increase in net cash provided by operating activities was primarily due to lower annual incentive payments and favorable changes in net working capital partially offset by lower earnings largely due to the impact of COVID-19.
On March 25, 2020, the company borrowed $100.0 million from its current revolving credit facility to preserve financial flexibility and enhance liquidity, given the increasing levels of uncertainty related to COVID-19. On April 3, 2020, the Company amended the existing credit agreement to effect certain changes, including, among others: (i) eliminating the $200.0 million unsecured term loan credit facility, the remaining outstanding balance ($140.0 million) of which was repaid in full on April 3, 2020 through the revolving credit facility; (ii) making certain financial and non-financial covenants less restrictive on the Company; (iii) modifying performance-based interest rate margins and undrawn fees; and (iv) extending the maturity date to April 3, 2025. The amended credit agreement also allows the Company to increase the size of the revolving credit facility or enter into one or more tranches of term loans if there is no event of default and the Company is in compliance with certain financial covenants. The Company made payments of $60.0 million on the amended revolving credit facility during the three months ended September 26, 2020. The balance under the facility was $180.0 million as of September 26, 2020.
On April 7, 2020, the Company entered into a definitive agreement to purchase a group annuity contract, under which an insurance company will be required to pay and administer pension payments to certain of the Company’s UK pension plan participants, or their designated beneficiaries, who have been receiving pension payments. The purchase of this group annuity contract will reduce the Company’s outstanding pension benefit obligation by approximately $36 million, representing approximately 30% of the total obligations of the Company’s qualified pension plans, and will be funded with pension plan assets and additional cash on hand. In connection with this transaction, the Company will record a one-time non-cash settlement charge in the second half of 2021 currently estimated between $18 million and $22 million, reflecting the accelerated recognition of a portion of unamortized actuarial losses in the plan. The actual settlement charge could differ from this estimate due to final data and plan wind-up expenses.

Impact of COVID-19 on Business
The Company continued to manage through the COVID-19 impacts during the third quarter, with a lesser impact to its financial results compared to the first six months of 2020. Our manufacturing facilities generally operated at normal capacity levels as production disruptions were minimal during the third quarter. The effects from COVID-19 continued to drive higher freight cost, as well as spending on personal protective equipment ("PPE"), additional personnel and employee transportation costs, partially offset by certain international government subsidies and COVID-19 relief programs.
The Company’s priorities continue to be first, on our associates, their families and the communities in which we operate; second, our customers; and third, long-term financial health of the company. In an effort to protect the health and safety of our employees, the Company has enacted numerous proactive, aggressive actions at its facilities globally, and implemented a number of safety procedures including hygiene and disinfection protocols, social distancing and wearing PPE. The Company expects these actions will continue for the foreseeable future.
During the first half of 2020, governments around the world enacted various measures in an effort to contain COVID-19 and slow its spread. These measures included orders to close all businesses not deemed “essential”, isolate residents to their homes or places of residence, and practice social distancing when engaging in essential activities, which disrupted certain of our operating locations in around the world. During the third quarter, all of our manufacturing facilities have been operating and are generally at normal capacity levels.
The Company continues to work with customers to meet production requirements for their products, many of which are considered essential, including healthcare and medical devices, transportation, communication and energy infrastructure.
The Company anticipates that the global health crisis caused by COVID-19 may continue to negatively impact its business activity for the foreseeable future. It is currently difficult to estimate the magnitude of the COVID-19 disruption, if future disruptions will occur due to a resurgence in COVID-19 cases and its impact on our employees, customers, suppliers and vendors. The Company will continue to actively monitor the situation and may take further actions altering our business operations that we determine are in the best interests of our employees, customers, partners, suppliers, and other stakeholders, or as required by federal, state, or local authorities. It is not clear what the potential effects any such alterations or modifications may have on our business and operations, including the effects on our customers, employees, and prospects, or on our financial results for the remainder of fiscal 2020.
Goodwill Impairment Assessment
The Company performs its annual goodwill impairment tests on the first day of the fiscal fourth quarter, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. As part of its interim review for indicators of impairment, management analyzed potential changes in the value of individual reporting units with goodwill based on each reporting unit’s operating results for the nine months ended September 26, 2020 compared to expected results. In addition, management considered how other key assumptions, including discount rates and expected long-term growth rates, used in last fiscal year’s impairment analysis, could be impacted by changes in market conditions and economic events. Management considered trends in these factors when performing its assessment of whether an interim impairment review was required for any reporting unit. Based on September 26, 2020 interim assessment, Management concluded that no events or changes in circumstances indicated that it was more likely than not that the fair value for any reporting unit had declined below its carrying value. Nevertheless, a continued global economic slowdown and further business disruption due to COVID-19 could result in changes to expectations of future financial results and key valuation assumptions.
During the second quarter of 2020, the Company recorded a non-cash charge of $33.8 million to recognize the impairment of goodwill in the automotive sensors reporting unit within the Automotive segment. The goodwill impairment charge was due to reductions in the estimated fair value for the automotive sensors reporting unit based on lower expectations for future revenue, profitability and cash flows as compared to the expectations of the 2019 annual goodwill impairment test. These lower future expectations were driven by projected extended declines in end market demand due to the COVID-19 pandemic. In addition, during the second quarter of 2020, certain customers notified the Company of their decision to delay future programs along with a customer canceling an existing program. The goodwill impairment charge was determined using Level 3 inputs, including discounted cash flow analysis and comparable marketplace fair value data. As of September 26, 2020, the automotive sensors reporting unit had $9.4 million of remaining goodwill.

Table of Contents
The semiconductor reporting unit has experienced declines in net sales for the nine months ended September 26, 2020 due to temporary shut-downs of its plants as well as outsourced manufacturing partners and lower customer demand primarily due to COVID-19. The Company continues to evaluate the impact of COVID-19 on its long-term expectations for this unit. Further negative developments having a significant impact on the estimated fair value of this reporting unit could result in future goodwill impairment charges. As of the September 30, 2019 annual goodwill impairment test, the semiconductors reporting unit estimated fair value exceeded its book value by approximately 42%. As of September 26, 2020, $473.3 million of goodwill was allocated to the semiconductors reporting unit. The semiconductors reporting unit is included within the Electronics segment.
Risks Related to Market Conditions
While the Company has not historically or currently as of September 26, 2020 had significant credit risk on its accounts receivable, the impact of the COVID-19 pandemic and associated economic slowdown may increase the Company’s credit risk on accounts receivable. It is possible that the Company’s customers may experience liquidity issues which may impact the timing of the collections on receivables. The Company will continue to evaluate how the ongoing pandemic may impact collectability.

Revolving Credit Facility/Term Loan
On March 4, 2016, the Company entered into a five-year credit agreement (“Credit Agreement”) with a group of lenders for up to $700.0 million. The Credit Agreement consisted of an unsecured revolving credit facility (“Revolving Credit Facility”) of $575.0 million and an unsecured term loan credit facility (“Term Loan”) of up to $125.0 million. In addition, the Company had the ability, from time to time, to increase the size of the Revolving Credit Facility and the Term Loan 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.
On October 13, 2017, the Company amended the Credit Agreement to increase the Revolving Credit Facility from $575.0 million to $700.0 million and increase the Term Loan 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 included the option for the Company to increase the size of the Revolving Credit Facility and the Term Loan 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 could be made in up to two advances. The first advance of $125.0 million occurred on October 13, 2017 and the second advance of $75.0 million occurred on January 16, 2018. For the Term Loan, the Company was required to make quarterly principal payments of 1.25% of the original term loan ($2.5 million quarterly) through maturity, with the remaining balance due on October 13, 2022. The Company paid $5.0 million of principal payments on the term loan before the Company amended the Credit Agreement on April 3, 2020 as discussed below.
On March 25, 2020, the company borrowed $100.0 million from the revolving credit facility to preserve financial flexibility and enhance liquidity, given the increasing levels of uncertainty related to coronavirus disease 2019 ("COVID-19").
On April 3, 2020, the Company amended the Credit Agreement to effect certain changes, including, among others: (i) eliminating the $200.0 million unsecured term loan credit facility, the remaining outstanding balance ($140.0 million) of which was repaid in full on April 3, 2020 through the revolving credit facility; (ii) making certain financial and non-financial

covenants less restrictive on the Company; (iii) modifying performance-based interest rate margins and undrawn fees; and (iv) extending the maturity date to April 3, 2025. The amended Credit Agreement also allows the Company to increase the size of the revolving credit facility or enter into one or more tranches of term loans if there is no event of default and the Company is in compliance with certain financial covenants. The Company made payments of $60.0 million on the amended revolving credit facility during the three months ended September 26, 2020. The balance under the facility was $180.0 million as of September 26, 2020.
Outstanding borrowings under the amended Credit Agreement bears interest, at the Company’s option, at either LIBOR, fixed for interest periods of one, two, three or six-month periods, plus 1.25% to 2.00%, or at the bank’s Base Rate, as defined, plus 0.25% to 1.00%, based upon the Company’s Consolidated Leverage Ratio, as defined. The Company was also required to pay commitment fees on unused portions of the credit agreement ranging from 0.125% to 0.20%, based on the Consolidated Leverage Ratio, as defined in the agreement. The amended Credit Agreement included 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 1.90% at September 26, 2020.
As of September 26, 2020, the Company had no amount outstanding in letters of credit and had available $245.1 million of borrowing capacity under the Revolving Credit Facility based on financial covenants. At September 26, 2020, the Company was in compliance with all covenants under the Credit Agreement.

Debt Covenants
The Company was in compliance with all covenants under the Credit Agreement and Senior Notes as of September 26, 2020 and currently expects to remain in compliance based on management’s estimates of operating and financial results for 2020. As of September 26, 2020, the Company met all the conditions required to borrow under the Credit Agreement and management expects the Company to continue to meet the applicable borrowing conditions. The ultimate magnitude of COVID-19, including the extent of its impact on our financial and operational results, which could be material, will be determined by the length of time that the pandemic continues, its effect on the demand for our products, as well as the effect of governmental regulations imposed in response to the pandemic. While we cannot at this time predict the impact of the COVID-19, it could have a material negative impact on our business, financial condition, results of operations and future cash flows which could impact the Company’s ability to comply with debt covenants in the future.

The increase in net cash provided by operating activities was primarily due to lower annual incentive payments and favorable changes in net working capital partially offset by lower earnings largely due to the impact of COVID-19.

During the nine months ended September 26, 2020, the company borrowed $100.0 million from its revolving credit facility to preserve financial flexibility and enhance liquidity, given the increasing levels of uncertainty related to COVID-19. On April 3, 2020, the Company amended the Credit Agreement to eliminate the $200.0 million unsecured term loan credit facility, with the remaining outstanding balance of $140.0 million repaid in full on April 3, 2020 through a new borrowing of $140.0 million under the recently amended revolving credit facility. The Company made payments of $60.0 million on the amended revolving credit facility during the third quarter of 2020.

ITEM 1A. RISK FACTORS
The COVID-19 pandemic could have a material adverse effect on our ability to operate, results of operations, financial condition, liquidity, and capital investments.
T he World Health Organization has declared the COVID-19 outbreak a pandemic, and the virus continues to spread in areas where we operate and sell our products. The COVID-19 pandemic and similar situations/circumstances in the future could have a material adverse effect on our ability to operate, results of operations, financial condition, liquidity, and capital investments. Several public health organizations have recommended, and some local governments have implemented, certain measures to slow and limit the transmission of the virus, including travel restrictions, shelter-in-place requirements and social distancing requirements. Such preventive measures, or others we may voluntarily put in place, may have a material adverse effect on our business for an indefinite period of time, such as the potential shut down of certain locations, decreased employee availability, potential border closures, disruptions to the businesses of our original equipment manufacturers ("OEMs") and channel partners, and others. Our suppliers and customers may also face these and other challenges, which could lead to a disruption in our supply chain as well as decreased demand for our products. These issues may also materially affect our future access to our sources of liquidity, particularly our cash flows from operations, financial condition, capitalization, and capital investments. These disruptions may continue to occur and may result in future impairment, restructuring and other charges. To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in the risk factors disclosed in Part I, Item 1a. Risk Factors of our Form 10-K, including those relating to our products and services, financial performance, debt covenant compliance and debt obligations. The ultimate magnitude of COVID-19, including the extent of its impact on our financial and operational results, which could be material, will be determined by the length of time that the pandemic continues, its effect on the demand for our services, as well as the effect of governmental regulations imposed in response to the pandemic. We cannot at this time predict the impact of the COVID-19 pandemic, but it could have a material adverse effect on our business, financial condition, results of operations and/or cash flows.
Other than the item listed above, there have been no material changes in our risk factors from those disclosed in our Annual Report on Form 10-K for our year ended December 28, 2019.
