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.
9



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.
 
Cash, Cash Equivalents and Restricted Cash

The following table provides a reconciliation of cash, cash equivalents and restricted cash at March 27, 2021 and December 26, 2020 reported within the Condensed Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Condensed Consolidated Statement of Cash Flows.

Total cash, cash equivalents and restricted cash $ 577,297  $ 687,525 

Recently Adopted Accounting Standards

In December 2019, the Financial Accounting Standards Board (FASB) issued ASU No. 2019-12, "Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes" as part of its initiative to reduce complexity in the accounting standards. The guidance is effective for fiscal years beginning after December 15, 2020 with early adoption permitted. The adoption of ASU 2019-12 did not have a material impact 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.

Hartland Controls

On January 28, 2021, the Company acquired Hartland Controls ("Hartland"), a manufacturer and leading supplier of electrical components used primarily in heating, ventilation, air conditioning (HVAC) and other industrial and control systems applications with annualized sales of approximately $70 million. The purchase price for Hartland was approximately $112.3 million and the operations of Hartland are included in the Industrial segment.

The total purchase consideration of $109.9 million, net of cash, cash equivalents, and restricted cash has been allocated, on a preliminary basis, to assets acquired and liabilities assumed, as of the completion of the acquisition, based on preliminary estimated fair values. The purchase consideration is subject to change for the final working capital adjustments. As of March 27, 2021, the Company had restricted cash of $1.7 million in an escrow account for general indemnification purposes. The purchase price allocation is preliminary because the evaluations necessary to assess the fair values of the net assets acquired are still in process. The primary areas that are not yet finalized relate to the completion of the valuations of certain acquired income tax assets and liabilities. As a result, these allocations are subject to change during the purchase price allocation period as the valuations are finalized.

10

The following table summarizes the purchase price allocation of the fair value of assets acquired and liabilities assumed in the Hartland acquisition:

(in thousands) Purchase Price
Allocation
Total purchase consideration:  
Cash, net of cash acquired, and restricted cash $ 109,852 
Allocation of consideration to assets acquired and liabilities assumed:
Trade receivables, net 14,305 
Inventories 36,306 
Other current assets 2,384 
Property, plant, and equipment 6,296 
Intangible assets 39,660 
Goodwill 38,929 
Other non-current assets 3,542 
Current liabilities (25,024)
Other non-current liabilities (6,546)
  $ 109,852 
All Hartland goodwill, other assets and liabilities were recorded in the Industrial segment and are primarily reflected in the Americas and Asia-Pacific geographic areas. The goodwill resulting from this acquisition consists largely of the Company’s expected future product sales and synergies from combining Hartland’s products and technology with the Company’s existing industrial products portfolio. Goodwill resulting from the Hartland acquisition is not expected to be deductible for tax purposes.
 
Included in the Company’s Condensed Consolidated Statements of Net Income for the three months ended March 27, 2021 are net sales of approximately $16.7 million, and a loss before income taxes of $2.2 million, since the January 28, 2021 acquisition of Hartland.

The Company recorded a $6.8 million step-up of inventory to its fair value as of the acquisition date based on the preliminary valuation. The step-up is being amortized as a non-cash charge to cost of goods sold during the first and second quarters of 2021, as the acquired inventory is sold, and reflected as other non-segment costs. During the three months ended March 27, 2021, the Company recognized a charge of $3.5 million for the amortization of this fair value inventory step-up.
 
During the three months ended March 27, 2021, the Company incurred approximately $0.7 million of legal and professional fees related to this acquisition recognized as Selling, general, and administrative expenses. These costs were reflected as other non-segment costs.

Pro Forma Results
The following table summarizes, on an unaudited pro forma basis, the combined results of operations of the Company and Hartland as though the acquisition had occurred as of December 29, 2019. The pro forma amounts presented are not necessarily indicative of either the actual consolidated results had the Hartland acquisition occurred as of December 29, 2019 or of future consolidated operating results.

Revolving Credit Facility

On April 3, 2020, the Company amended its 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 $30.0 million on the amended revolving credit facility during the three months ended March 27, 2021. The balance under the facility was $100.0 million as of March 27, 2021.

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 1.61% at March 27, 2021.

As of March 27, 2021, the Company had no amount outstanding in letters of credit and had available $571.3 million of borrowing capacity under the Revolving Credit Facility based on financial covenants. At March 27, 2021, the Company was in compliance with all covenants under the Credit Agreement.

9. 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.

Other Investments
 
17

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. As of March 27, 2021 and December 26, 2020, the balances of these investments were both $0.5 million. 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.

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 March 27, 2021 to the Company’s valuation techniques used to measure asset and liability fair values on a recurring basis. As of March 27, 2021 and December 26, 2020, the Company did not hold any non-financial assets or liabilities that are required to be measured at fair value on a recurring basis.

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 credit facilities’ fair values approximate book value at March 27, 2021 and December 26, 2020, 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 March 27, 2021 and December 26, 2020 were as follows:

The Company recognized impairment charges of $1.9 million for the land and building and $0.3 million for a certain patent as a result of the Company’s announcement to consolidate a manufacturing facility within the Industrial segment during the first quarter of 2020. See Note 7, Restructuring, Impairment and Other Charges, for further discussion. The fair value of the land and building was valued using a real estate appraisal and classified as a Level 3 input under the fair value hierarchy.

10. Benefit Plans
 
The Company has company-sponsored defined benefit pension plans covering employees in the U.K., Germany, the Philippines, China, Japan, Mexico, Italy and France. The amount of the retirement benefits provided under the plans is based on years of service and final average pay.
 
The Company recognizes interest cost, expected return on plan assets, and amortization of prior service, net within Other (income) expense, net in the Condensed Consolidated Statements of Net Income. The components of net periodic benefit cost for the three months ended March 27, 2021 and March 28, 2020 were as follows: 
 
  For the Three Months Ended
(in thousands) March 27, 2021 March 28, 2020
Components of net periodic benefit cost:

Expected return on plan assets (367) (727)
Amortization of prior service and net actuarial loss 331  145 
Net periodic benefit cost $ 1,106  $ 694 

The Company expects to make approximately $2.2 million of contributions to the plans and pay $3.8 million of benefits directly in 2021.

The Company also sponsors certain post-employment plans in foreign countries and other statutory benefit plans. The Company recorded expense of $0.5 million for both the three months ended March 27, 2021 and March 28, 2020, respectively, in Cost of Sales and Other (income) expense, net within the Condensed Consolidated Statements of Net Income. For the three months ended March 27, 2021 and March 28, 2020, the pre-tax amounts recognized in other comprehensive income (loss) as components of net periodic benefit costs for these plans were both $0.2 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 directly pay and administer pension payments to certain of the Company’s U.K. pension plan participants, or their designated beneficiaries. The purchase of this group annuity contract will reduce the Company’s outstanding pension benefit obligation by approximately $55 million, representing approximately 37% 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 currently estimated between $18 million and $22 million in the fourth quarter of 2021, reflecting the accelerated recognition of unamortized actuarial losses
19

in the plan. The actual amount and timing of the 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 of 2020. Additionally, the Company made a cash contribution of $10.4 million (£8.4 million) under this agreement during the second quarter of 2020.

12. Income Taxes
 
The effective tax rate for the three months ended March 27, 2021 was 20.6%, compared to the effective tax rate for the three months ended March 28, 2020 of 30.6%. The effective tax rate for the 2021 period is lower than the effective tax rate for the comparable 2020 period primarily due to an increase in the forecasted income earned in lower tax jurisdictions in 2021 as compared to 2020. The effective tax rate for the 2021 period is approximately the same as the applicable U.S. statutory rate.

15. Segment Information
 
The Company and its subsidiaries design, manufacture and sell components and modules empowering a sustainable, connected, and safer 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 motor drives and power conversion, automotive electronics, electric vehicle and related infrastructure, power supplies, data centers and telecommunications, medical devices, alternative energy, building and home automation, appliances, and mobile electronics.

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 for internal combustion engine, hybrid and electric vehicles including blade fuses, battery cable
22

protectors, resettable fuses, high-current fuses, and high-voltage fuses. Commercial vehicle products include fuses, switches, relays, and power distribution modules used in applications serving a number of end markets, including heavy truck, construction, agriculture and material handling. Automotive sensor products include a wide range of automotive and commercial vehicle products designed to monitor the passenger compartment occupant's safety and environment as well as the vehicle’s powertrain.

Industrial Segment: Consists of industrial circuit protection products (i.e. fuses, power distribution modules, switches) and industrial control products (i.e. relays, transformers, contactors, sensors). These products are used in a variety of applications and end-markets including: Renewable Energy, Energy Storage, HVAC, Electric Vehicle Infrastructure, Industrial Equipment, Industrial Automation, Construction, Mining, and Oil & Gas.

Executive Summary
 
For the first quarter of 2021, the Company recognized net sales of $463.8 million compared to $346.1 million in the first quarter of 2020 representing an increase of $117.7 million, or 34.0%. The increase was driven by higher volumes across all businesses in the Electronics and Automotive segments, $16.7 million or 3.6% of net sales from the Hartland acquisition within the Industrial segment and $12.4 million or 3.6% of favorable changes in foreign exchange rates. The Company recognized net income of $57.7 million, or $2.32 per diluted share, in the first quarter of 2021 compared to net income of $24.6 million, or $1.00 per diluted share in the first quarter of 2020. The increase in net income reflects higher operating income of $31.7 million driven by a $23.3 million and $6.2 million increase in operating income in the Electronics and Automotive segments, respectively, increases of $9.7 million of unrealized gains associated with our equity investments partially offset by higher foreign exchange losses of $4.3 million.

On January 28, 2021, the Company acquired Hartland Controls ("Hartland"), a manufacturer and leading supplier of electrical components used primarily in heating, ventilation, air conditioning (HVAC) and other industrial and control systems applications with annualized sales of approximately $70 million. The purchase price for Hartland was approximately $112.3 million and the operations of Hartland are included in the Industrial segment.

Net cash provided by operating activities was $50.2 million for the three months ended March 27, 2021 as compared to $45.3 million for the three months ended March 28, 2020. The increase in net cash provided by operating activities was primarily due to higher cash earnings partially offset by increases in working capital resulting from higher sales growth.
 

Impact of COVID-19 on Business

The effects from COVID-19 continue to drive increased costs, though lower than 2020 levels. Ongoing costs include spending on personal protective equipment ("PPE"), additional personnel and employee transportation costs, and manufacturing inefficiencies, as well as an increase in freight costs due to the transportation capacity constraints across the world.

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 fiscal year 2021.

Net Sales
 
Net sales increased $117.7 million or 34.0% including $12.4 million or 3.6% of favorable changes in foreign exchange rates for the first quarter of 2021 compared to the first quarter of 2020. The increase was primarily due to higher sales of $72.3 million and $23.8 million, respectively, in the Electronics and Automotive segments driven by higher volumes across all businesses within these segments. The volume increase within the Electronics segment was led by greater customer demand for products and devices for work-from-home and stay-at-home needs, and strong global automotive demand driving an increase for products used in automotive electronics and electric vehicles. The volume increase within the Automotive segment was due to stronger global auto and commercial vehicle market demand. The remaining increase in net sales was due to $16.7 million of net sales resulting from the Hartland acquisition included in the Industrial segment.


Cost of Sales

Cost of sales was $303.3 million, or 65.4% of net sales, in 2021, compared to $221.7 million, or 64.1% of net sales, in 2020. The increase in cost of sales was primarily due to greater volume in the Electronics and Automotive segments driven by the factors discussed above along with the acquisition of Hartland. As a percent of net sales, cost of sales increased 1.3% driven by higher freight costs of $7.3 million, or 0.9%, the Hartland purchase accounting inventory charges of $3.5 million or 0.8%, and higher commodity costs partially offset by cost reductions.


Gross Profit
 
Gross profit was $160.5 million, or 34.6% of net sales, in the first quarter of 2021 compared to $124.4 million, or 35.9% of net sales, for the first quarter of 2020. The $36.1 million increase in gross profit was primarily due to higher volume in the Electronics and Automotive segments. The decrease in gross margin of 1.3% was primarily due to the higher freight costs of $7.3 million or 0.9%, the purchase accounting inventory charges of $3.5 million or 0.8%, higher commodity costs, and unfavorable price and foreign exchange partially offset by higher volumes within the Electronics and Automotive segments.

Operating Expenses
 
Total operating expenses were $84.0 million, or 18.1% of net sales, for the first quarter of 2021 compared to $79.6 million, or 23.0% of net sales, for the first quarter of 2020. The increase in operating expenses of $4.4 million was primarily due to higher selling, general and administrative expenses of $7.1 million largely due to higher accrued incentive compensation and the
27

Table of Contents
Hartland acquisition partially offset by a $1.9 million gain from the sale of a building within the Electronics segment. The increase in operating expenses was also partially offset by lower restructuring, impairment and other charges of $3.5 million.

Operating Income
 
Operating income was $76.5 million, an increase of $31.7 million, or 70.9%, for the first quarter of 2021 compared to $44.8 million for the first quarter of 2020. The increase in operating income was primarily due to higher gross profit from the Electronics and Automotive segments. Operating margins increased from 12.9% in the first quarter of 2020 to 16.5% in the first quarter of 2021 driven by the factors mentioned above.
  
Income Before Income Taxes
 
Income before income taxes was $72.7 million, or 15.7% of net sales, for the first quarter of 2021 compared to $35.5 million, or 10.3% of net sales, for the first quarter of 2020. In addition to the factors impacting comparative results for operating income discussed above, income before income taxes was primarily impacted by increases of $9.7 million of unrealized gains associated with our equity investments partially offset by higher foreign exchange losses of $4.3 million.

Income Taxes
 
Income tax expense for the first quarter of 2021 was $15.0 million, or an effective tax rate of 20.6%, compared to income tax expense of $10.9 million, or an effective tax rate of 30.6%, for the first quarter of 2020. The effective tax rate for the first quarter of 2021 is lower than the effective tax rate for the comparable 2020 period, primarily due to an increase in the forecasted income earned in lower tax jurisdictions in 2021 compared to 2020. The effective tax rate for the 2021 period is approximately the same as the applicable U.S. statutory rate.


Segment Results of Operations
 
The Company reports its operations by the following segments: Electronics, Automotive and Industrial. Segment information is described more fully in Note 15, Segment Information, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report.
 
The following table is a summary of the Company’s net sales by segment:

Total $ 463,794  $ 346,096  $ 117,698  34.0  %

Electronics Segment
 
Net sales increased $72.3 million, or 33.8%, in the first quarter of 2021 compared to the first quarter of 2020 and included favorable changes in foreign exchange rates of $6.5 million. The sales increase was primarily due to increased volume for the electronics products and semiconductor businesses of $47.8 million and $24.5 million, respectively. The volume increases were led by greater customer demand for products and devices for work-from-home and stay-at-home needs, and strong global automotive demand driving an increase for products used in automotive electronics and electric vehicles. The first quarter of 2020 also included production disruptions due to the impact of COVID-19. 


Automotive Segment
 
Net sales increased $23.8 million, or 22.7%, in the first quarter of 2021 compared to the first quarter of 2020 and included favorable changes in foreign exchange rates of $5.6 million. The sales increase was due to higher volume in passenger car products, commercial vehicle products, and the automotive sensors business of $15.3 million, $4.4 million, and $4.1 million,

respectively. These increases were due to stronger global auto and commercial vehicle market demand. Our Asia region experienced the most growth driven by an increase in global auto market demand as compared to the first quarter of 2020 that had production disruptions due to the impact of COVID-19. Sales also grew due to the launch of new products and higher content per vehicle.

Industrial Segment
 
Net sales increased by $21.6 million, or 79.6%, in the first quarter of 2021 compared to the first quarter of 2020, which included favorable changes in foreign exchange rates of $0.3 million. The increase in net sales was primarily due to incremental net sales of $16.7 million or 61.5% from the Hartland acquisition, higher volume of $4.5 million in the power fuse business, and the transfer of the temperature sensor product line totaling $1.9 million which was previously reported in the Electronics segment, partially offset by lower volume in the relay business.

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

On April 3, 2020, the Company amended its 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 $30.0 million on the amended revolving credit facility during the three months ended March 27, 2021. The balance under the facility was $100.0 million as of March 27, 2021.

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 1.61% at March 27, 2021.

As of March 27, 2021, the Company had no amount outstanding in letters of credit and had available $571.3 million of borrowing capacity under the Revolving Credit Facility based on financial covenants. At March 27, 2021, the Company was in compliance with all covenants under the Credit Agreement.

Acquisitions
On January 28, 2021, the Company acquired Hartland Controls ("Hartland"), a manufacturer and leading supplier of electrical components used primarily in heating, ventilation, air conditioning (HVAC) and other industrial and control systems applications with annualized sales of approximately $70 million. The purchase price for Hartland was approximately $112.3 million and the operations of Hartland Controls are included in the Industrial segment. The net cash payment of $109.9 million for this acquisition was funded by the Company's cash on hand.

Dividends
 
During the first quarter of 2020 the Company paid quarterly dividends of $11.8 million to the shareholders. On April 28, 2021, the Board of Directors of the Company declared a quarterly cash dividend of $0.48 per share, payable on June 3, 2021 to stockholders of record as of May 20, 2021.

U.K. pension plan

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 directly pay and administer pension payments to certain of the Company’s U.K. pension plan participants, or their designated beneficiaries. The purchase of this group annuity contract will reduce the Company’s outstanding pension benefit obligation by approximately $55 million, representing approximately 37% 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 currently estimated between $18 million and $22 million in the fourth quarter of 2021, reflecting the accelerated recognition of unamortized actuarial losses in the plan. The actual amount and timing of the 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 of 2020. Additionally, the Company made a cash contribution of $10.4 million (£8.4 million) under this agreement during the second quarter of 2020.

Net cash provided by operating activities was $50.2 million for the three months ended March 27, 2021 as compared to $45.3 million for the three months ended March 28, 2020. The increase in net cash provided by operating activities was primarily due to higher cash earnings partially offset by increases in working capital resulting from higher sales growth. 

Cash Flow from Investing Activities
 
Net cash used in investing activities was $122.0 million for the three months ended March 27, 2021 compared to $16.5 million during the three months ended March 28, 2020. Net cash paid for the Hartland acquisition was $109.9 million for the three
