PLEXUS CORP. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
FOR THE THREE AND SIX MONTHS ENDED APRIL 3, 2021 AND APRIL 4, 2020
Unaudited
1. Basis of Presentation
Basis of Presentation:
The accompanying Condensed Consolidated Financial Statements included herein have been prepared by Plexus Corp. and its subsidiaries (together “Plexus” or the “Company”) without audit and pursuant to the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (“SEC”). The accompanying Condensed Consolidated Financial Statements reflect all adjustments, which include normal recurring adjustments necessary for the fair statement of the consolidated financial position of the Company as of April 3, 2021 and October 3, 2020, the results of operations and shareholders' equity for the three and six months ended April 3, 2021 and April 4, 2020, and the cash flows for the same six month periods.
The Company’s fiscal year ends on the Saturday closest to September 30. The Company uses a “4-4-5” weekly accounting system for the interim periods in each quarter. Each quarter, therefore, ends on a Saturday at the end of the 4-4-5 period. Periodically, an additional week must be added to the fiscal year to re-align with the Saturday closest to September 30. The first quarter of fiscal 2020 included 14 weeks while all other fiscal quarters presented herein included 13 weeks.
Certain information and footnote disclosures, normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"), have been condensed or omitted pursuant to the SEC’s rules and regulations dealing with interim financial statements. However, the Company believes that the disclosures made in the Condensed Consolidated Financial Statements included herein are adequate to make the information presented not misleading. It is suggested that these Condensed Consolidated Financial Statements be read in conjunction with the Consolidated Financial Statements and notes thereto included in the Company’s 2020 Annual Report on Form 10-K.
Certain prior period amounts have been reclassified to conform to the current period presentation.
The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and notes thereto. The full extent to which the COVID-19 outbreak will impact the Company's business and operating results will depend on future developments that are highly uncertain and cannot be accurately predicted. The Company has considered information available as of the date of issuance of these financial statements and is not aware of any specific events or circumstances that would require an update to its estimates or judgments, or a revision of the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information becomes available. Actual results could differ materially from these estimates.
Recently Adopted Accounting Pronouncements:
In June 2016, the FASB issued ASU 2016-13, which replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses and required consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company adopted this guidance during the first quarter of fiscal 2021 with no material impact to the Company's Consolidated Financial Statements.
In February 2016, the FASB issued ASU 2016-02 ("Topic 842"), which is intended to improve financial reporting of lease transactions by requiring lessees to recognize most leases as a right-of-use (“ROU”) asset and lease liability on their balance sheets for the rights and obligations created by leases, but record expenses on their income statements in a similar manner. Topic 842 also requires disclosures regarding the amount, timing and judgments related to accounting for an entity’s leases and related cash flows. On September 29, 2019, the Company adopted Topic 842 using the modified retrospective method of adoption, which allows financial information for comparative periods prior to adoption not to be updated. Upon adoption, the Company recognized a $1.1 million reduction in retained earnings as a result of two existing build-to-suit arrangements for the facilities in Guadalajara, Mexico that were reassessed to be finance leases under the new standard.
In August 2017, the FASB issued ASU 2017-12 related to the accounting for hedging activities. The pronouncement expands and refines hedge accounting, aligns the recognition and presentation of the effects of hedging instruments and hedge items in the financial statements, and includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The Company adopted this guidance during the first quarter of fiscal 2020 with no material impact to the Company's Consolidated Financial Statements; however, the impact of the new standard on future periods will depend on the facts and circumstances of future transactions.

On June 15, 2018, the Company entered into a Note Purchase Agreement (the “2018 NPA”) pursuant to which it issued an aggregate of $150.0 million in principal amount of unsecured senior notes, consisting of $100.0 million in principal amount of 4.05% Series A Senior Notes, due on June 15, 2025, and $50.0 million in principal amount of 4.22% Series B Senior Notes, due on June 15, 2028 (collectively, the “2018 Notes”), in a private placement. The 2018 NPA includes customary operational and financial covenants with which the Company is required to comply, including, among others, maintenance of certain financial ratios such as a total leverage ratio and a minimum interest coverage ratio. The 2018 Notes may be prepaid in whole or in part at any time, subject to payment of a make-whole amount; interest on the 2018 Notes is payable semiannually. As of April 3, 2021, the Company was in compliance with the covenants under the 2018 NPA.
On May 15, 2019, the Company refinanced its then-existing senior unsecured revolving credit facility by entering into a new 5-year senior unsecured revolving credit facility (referred to as the "Credit Facility"), which expanded the maximum commitment from $300.0 million to $350.0 million and extended the maturity from July 5, 2021 to May 15, 2024. The maximum commitment under the Credit Facility may be further increased to $600.0 million, generally by mutual agreement of the Company and the lenders, subject to certain customary conditions. During the six months ended April 3, 2021, the highest daily borrowing was $148.0 million and the average daily borrowings were $48.2 million. The Company borrowed $151.0 million and repaid $113.0 million of revolving borrowings ("revolving commitment") under the Credit Facility during the six months

ended April 3, 2021. As of April 3, 2021, the Company was in compliance with all financial covenants relating to the Credit Agreement, which are generally consistent with those in the 2018 NPA discussed above. The Company is required to pay a commitment fee on the daily unused revolving commitment based on the Company's leverage ratio; the fee was 0.125% as of April 3, 2021.
To further ensure the Company's ability to meet it working capital and fixed capital requirements, on April 29, 2020, the Company entered into Amendment No. 1 to the Credit Agreement (the "Amendment") in response to the COVID-19 outbreak, which amended the Credit Agreement, dated as of May 15, 2019. The Amendment modified certain provisions of the Credit Facility to, among other things, provide for a 364 day unsecured delayed draw term loans ("Term Loans") for $138.0 million. Term Loans borrowed under the new facility were funded in a single draw on May 4, 2020 and were scheduled to mature on April 28, 2021. On January 29, 2021, the Company terminated the Term Loans through repayment of the $138.0 million outstanding using borrowings from the revolving commitment under the Credit Facility. Outstanding Term Loans bore interest, at the Company’s option, at a eurocurrency rate (subject to a floor of 1.0%) plus a margin of 1.75% per annum or at a base rate (subject to a floor of 2.0%) plus a margin of 0.75% per annum.
The fair value of the Company’s debt, excluding finance lease and other financing obligations, was $199.6 million and $299.3 million as of April 3, 2021 and October 3, 2020, respectively. The carrying value of the Company's debt, excluding finance lease and other financing obligations, was $188.0 million and $288.0 million as of April 3, 2021 and October 3, 2020, respectively. If measured at fair value in the financial stateme nts, the Company's debt would be classified as Level 2 in the fair value hierarchy. Refer to Note 4, "Derivatives and Fair Value Measurements," for further information regarding the Company's fair value calculations and classifications.
4. Derivatives and Fair Value Measurements
All derivatives are recognized in the accompanying Condensed Consolidated Balance Sheets at their estimated fair value. The Company uses derivatives to manage the variability of foreign currency obligations. The Company has cash flow hedges related to forecasted foreign currency obligations, in addition to non-designated hedges to manage foreign currency exposures associated with certain foreign currency denominated assets and liabilities. The Company does not enter into derivatives for speculative purposes.
The Company designates some foreign currency exchange contracts as cash flow hedges of forecasted foreign currency expenses. Changes in the fair value of the derivatives that qualify as cash flow hedges are recorded in "Accumulated other comprehensive loss" in the accompanying Condensed Consolidated Bala nce Sheets until earnings are affected by the variability of the cash flows. In the next twelve months, the Company estimates that $0.7 million of unrealized gains, n et of tax, related to cash flow hedges will be reclassified from other comprehensive (loss) income into earnings. Changes in the fair value of the non-designated derivatives related to recognized foreign currency denominated assets and liabilities are recorded in "Miscellaneous, net" in the accompanying Condensed Consolidated Statements of Comprehensive Income (Loss).
The Company enters into forward currency exchange contracts for its operations in Malaysia and Mexico on a rolling basis. The Company had cash flow hedges outstanding with a notional valu e of $106.7 million as of April 3, 2021, and a notional value of $96.8 million as of October 3, 2020. These forward currency contracts fix the exchange rates for the settlement of future foreign currency obligations that have yet to be realized. The total fair value of the forward currency exchange contracts was a $0.7 million asset as of April 3, 2021, and a $1.2 million asset as of October 3, 2020.
The Company had additional forward currency exchange contracts outstanding as of April 3, 2021, with a notional value of $27.2 million; t here were $15.8 million of such contracts outstanding as of October 3, 2020. The Company did not designate these derivative instruments as hedging instruments. The net settlement amount (fair value) related to these contracts is recorded on the Condensed Consolidated Balance Sheets as either a current or long-term asset or liability, depending on the term, and as an element of "Miscellaneous, net" in the accompanying Condensed Consolidated Statements of Comprehensive Income (Loss). The total fair value of these derivatives was a $0.3 million liability as of April 3, 2021, and a less than $0.1 million asset as of October 3, 2020.

Fair Value Measurements:
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (or exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses quoted market prices when available or discounted cash flows to calculate fair value. The accounting guidance establishes a fair value hierarchy based on three levels of inputs that may be used to measure fair value. The input levels are:
Level 1: Quoted (observable) market prices in active markets for identical assets or liabilities.
Level 2: Inputs other than Level 1 that are observable, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.
Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the asset or liability.
The following table lists the fair values of assets of the Company’s derivatives as of April 3, 2021 and October 3, 2020, by input level:

Fair Value Measurements Using Input Levels Asset (in thousands)
April 3, 2021 |  | Level 1 |  | Level 2 |  | Level 3 |  | Total
Derivatives |  |  |  |  |  |  |  |

Derivatives |  |  |  |  |  |  |  |
Foreign currency forward contracts |  | $ | — |  |  | $ | 1,201 |  |  | $ | — |  |  | $ | 1,201 |

The fair value of foreign currency forward contracts is determined using a market approach, which includes obtaining directly or indirectly observable values from third parties active in the relevant markets. Inputs in the fair value of the foreign currency forward contracts include prevailing forward and spot prices for currency.
5. Income Taxes
Income tax expense for the three and six months ended April 3, 2021 was $4.7 million and $10.1 million, respectively, compared to $1.2 million and $4.4 million for the three and six months ended April 4, 2020, respectively.
The effective tax rates for the three and six months ended April 3, 2021 was 10.1% and 11.5%, respectively, compared to the effective tax rates of 8.2% and 9.1% for the three and six months ended April 4, 2020. The effective tax rate for the three and six months ended April 3, 2021 increased from the effective tax rate for the three and six months ended April 4, 2020, primarily due to a net $0.8 million benefit for special tax items during the three months ended January 4, 2020, as well as a change in the geographic distribution of pre-tax book income for the three and six months ended April 3, 2021. The increase in the effective tax rate was partially offset by a tax benefit of $0.9 million recognized for the three months ended April 3, 2021 related to the release of a full valuation allowance for a jurisdiction within the EMEA segment related to a settlement of an income tax audit.
There were no material additions to the amount of unrecognized tax benefits recorded for uncertain tax positions as of April 3, 2021. The Company recognizes accrued interest and penalties on uncertain tax positions as a component of income tax expense. The amount of interest and penalties recorded for the three and six months ended April 3, 2021 was not material.

One or more uncertain tax positions may be settled within the next 12 months. Settlement of these matters is not expected to have a material effect on the Company's consolidated results of operations, financial position and cash flows. The Company is not currently under examination by taxing authorities in the U.S. The Company is under audit in various foreign jurisdictions but settlement is not expected to have a material impact.
The Company maintains valuation allowances when it is more likely than not that all or a portion of a net deferred tax asset will not be realized. During the three months ended April 3, 2021, the Company released a full valuation allowance for a jurisdiction within the EMEA segment related to the settlement of an income tax audit. The Company continues to record a full valuation allowance against its net deferred tax assets in certain jurisdictions within the EMEA segment and a partial valuation against its net deferred tax assets in certain jurisdictions within the AMER segment, as it was more likely than not that these assets would not be fully realized based primarily on historical performance. The Company will continue to provide a valuation allowance against its net deferred tax assets in each of the applicable jurisdictions going forward until it determines it is more likely than not that the deferred tax assets will be realized.
6. Earnings Per Share
The following is a reconciliation of the amounts utilized in the computation of basic and diluted earnings per share for the three and six months ended April 3, 2021 and April 4, 2020 (in thousands, except per share amounts):

8. Share-Based Compensation
The Company recognized $6.5 million and $11.8 million of compensation expense associated with share-based awards for the three and six months ended April 3, 2021, respectively, and $5.8 million and $10.8 million for the three and six months ended April 4, 2020, respectively.
Performance stock units ("PSUs") are payable in shares of the Company's common stock. For PSUs issued in fiscal year 2020 and earlier, the PSUs vest based on the relative total shareholder return ("TSR") of the Company's common stock as compared to the companies in the Russell 3000 index, a market condition, and the Company's economic return performance during the three year performance period, a performance condition. In the first quarter of fiscal 2021, the Company updated the market condition for PSUs based on TSR to the S&P 400 index for all future PSU grants, including those granted in 2021. The Company uses the Monte Carlo valuation model to determine the fair value of PSUs at the date of grant for PSUs that vest based on the relative TSR of the Company's common stock. The Company uses its stock price on grant date as the fair value assigned to PSUs that vest based on the Company's economic return performance. The number of shares that may be issued pursuant to PSU grants that have not fully vested ranges from zero to 0.4 million and is dependent upon the Company's TSR and economic return performance over the applicable performance periods.
The Company recognizes share-based compensation expense over the share-based awards' vesting period.
9. Litigation
The Company is party to lawsuits in the ordinary course of business. Management does not believe that these proceedings, individually or in the aggregate, will have a material positive or adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

10. Reportable Segments
Reportable segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or group, in assessing performance and allocating resources. The Company uses an internal management reporting system, which provides important financial data to evaluate performance and allocate the Company’s resources on a regional basis. Net sales for the segments are attributed to the region in which the product is manufactured or the service is performed. The Company operates in the Americas ("AMER"), Asia-Pacific ("APAC") and Europe, Middle East, and Africa ("EMEA"). The services provided, manufacturing processes used, class of customers serviced and order fulfillment processes used are similar and generally interchangeable across the segments. A segment’s performance is evaluated based upon its operating income (loss). A segment’s operating income (loss) includes its net sales less cost of sales and selling and administrative expenses, but excludes corporate and other expenses. Corporate and other expenses primarily represent corporate selling and administrative expenses, restructuring and impairment charges and other charges, if any. These costs are not allocated to the segments, as management excludes such costs when assessing the performance of the segments. Inter-segment transactions are generally recorded at amounts that approximate arm’s length transactions. The accounting policies for the segments are the same as for the Company taken as a whole.
Information about the Company’s three reportable segments for the three and six months ended April 3, 2021 and April 4, 2020, respectively, is as follows (in thousands):

11. Guarantees
The Company offers certain indemnifications under its customer manufacturing agreements. In the normal course of business, the Company may from time to time be obligated to indemnify its customers or its customers’ customers against damages or liabilities arising out of the Company’s negligence, misconduct, breach of contract, or infringement of third-party intellectual property rights. Certain agreements have extended broader indemnification, and while most agreements have contractual limits, some do not. However, the Company generally does not provide for such indemnities and seeks indemnification from its customers for damages or liabilities arising out of the Company’s adherence to customers’ specifications or designs or use of materials furnished, or directed to be used, by its customers. The Company does not believe its obligations under such indemnities are material.
In the normal course of business, the Company also provides its customers a limited warranty covering workmanship, and in some cases materials, on products manufactured by the Company. Such warranty generally provides that products will be free from defects in the Company’s workmanship and meet mutually agreed-upon specifications for periods generally ranging from 12 months to 24 months. The Company’s obligation is generally limited to correcting, at its expense, any defect by repairing or replacing such defective product. The Company’s warranty generally excludes defects resulting from faulty customer-supplied components, design defects or damage caused by any party or cause other than the Company.
The Company provides for an estimate of costs that may be incurred under its limited warranty at the time product revenue is recognized and establishes additional reserves for specifically identified product issues. These costs primarily include labor and materials, as necessary, associated with repair or replacement and are included in the Company's accompanying Condensed Consolidated Balance Sheets in "other accrued liabilities." The primary factors that affect the Company’s warranty liability include the value and the number of shipped units and historical and anticipated rates of warranty claims. As these factors are impacted by actual experience and future expectations, the Company assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.
Below is a table summarizing the activity related to the Company’s limited warranty liability for the six months ended April 3, 2021 and April 4, 2020 (in thousands):

|  | Six Months Ended
|  | April 3, 2021 |  | April 4, 2020
Reserve balance, beginning of period |  | $ | 6,386 |  |  | $ | 6,276 |
Accruals for warranties issued during the period |  | 967 |  |  | 1,554 |
Settlements (in cash or in kind) during the period |  | (1,747) |  |  | (1,466) |
Reserve balance, end of period |  | $ | 5,606 |  |  | $ | 6,364 |

12. Shareholders' Equity
On August 20, 2019, the Board of Directors approved a share repurchase plan under which the Company is authorized to repurchase $50.0 million of its common stock (the "2019 Program"). During the six months ended April 3, 2021, the Company completed the 2019 Program by repurch asing 73,560 shares under this program for $5.3 million and at an average price of $72.44. During the three months ended April 4, 2020, the Company repurchased 224,564 shares under this program for $13.2 million at an average price of $58.57 per share. During the six months ended April 4, 2020, the Company repurchased 315,231 shares under this program for $19.5 million at an average price of $61.81.
On August 13, 2020, the Board of Directors approved a new share repurchase program that authorizes the Company to repurchase up to $50.0 million of its common stock (the "2021 Program") beginning upon expiration of the Company’s 2019 Program. On November 18, 2020, the Board of Directors approved an additional $50.0 million in share repurchase authority under the existing 2021 Program such that there now exists a total of $100.0 million in share repurchase authority under the program. During the three months ended April 3, 2021, the Company repurchased 349,297 shares under this program for $29.1 million at an average price of $83.39 per share. During the six months ended April 3, 2021, the Company repurchased 582,808 shares under this program for $46.6 million at an average price of $79.91. As of April 3, 2021, $53.4 million of authority remained under the 2021 Program. The 2021 Program has no expiration.
All shares repurchased under the aforementioned programs were recorded as treasury stock.

13. Trade Accounts Receivable Sale Programs
The Company has Master Accounts Receivable Purchase Agreements with MUFG Bank, New York Branch (formerly known as The Bank of Tokyo-Mitsubishi UFJ, Ltd.) (the "MUFG RPA"), and HSBC Bank (China) Company Limited, Xiamen branch (the "HSBC RPA"), under which the Company may elect to sell receivables; at a discount. These facilities are uncommitted facilities. The maximum facility amount under the MUFG R PA as of April 3, 2021 is $340.0 million. The maximum facility amount under the HSBC RPA as of April 3, 2021 is $60.0 million. The MUFG RPA will be automatically extended each year unless any party gives no less than 10 days prior notice that the agreement should not be extended. The contract length terms of the HSBC RPA are generally consistent with the terms of the MUFG RPA previously discussed.
Transfers of receivables under the programs are accounted for as sales and, accordingly, receivables sold under the programs are excluded from accounts receivable on the Condensed Consolidated Balance Sheets and are reflected as cash provided by operating activities on the Condensed Consolidated Statements of Cash Flows. Proceeds from the transfer reflect the face value of the receivables less a discount. The sale discount is recorded within "Miscellaneous, net" in the Condensed Consolidated Statements of Comprehensive Income (Loss) in the period of the sale.
The Compan y sold $195.6 million and $188.3 million of trade accounts receivable under these programs, or their predecessors, during the three months ended April 3, 2021 and April 4, 2020, respectively, in exchange for cash proceeds of $195.1 million and $187.4 million, respectively.
The Company sold $394.0 million and $416.1 million of trade accounts receivable under these programs, or their predecessors, during the six months ended April 3, 2021 and April 4, 2020, respectively, in exchange for cash proceeds of $392.9 million and $414.0 million, respectively.
14. Revenue from Contracts with Customers
Significant Judgments
Revenue is recognized over time for arrangements with customers for which: (i) the Company's performance does not create an asset with an alternative use to the Company, and (ii) the Company has an enforceable right to payment, including reasonable profit margin, for performance completed to date. Revenue recognized over time is estimated based on costs incurred to date plus a reasonable profit margin. If either of the two conditions noted above are not met to recognize revenue over time, revenue is recognized following the transfer of control of such products to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying arrangement.
The Company recognizes revenue when a contract exists and when, or as, it satisfies a performance obligation by transferring control of a product or service to a customer. Contracts are accounted for when they have approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer.
The Company generally enters into a master services arrangement that establishes the framework under which business will be conducted. These arrangements represent the master terms and conditions of the Company's services that apply to individual orders, but they do not commit the customer to work with, or to continue to work with, the Company nor do they obligate the customer to any specific volume or pricing of purchases. Moreover, these terms can be amended in appropriate situations.
Customer purchase orders are received for specific quantities with predominantly fixed pricing and delivery requirements. Thus, for the majority of our contracts, there is no guarantee of any revenue to the Company until a customer submits a purchase order. As a result, the Company generally considers its arrangement with a customer to be the combination of the master services arrangement and the purchase order. Most of the Company's arrangements with customers create a single performance obligation as the promise to transfer the individual manufactured product or service is capable of being distinct.
The Company’s performance obligations are satisfied over time as work progresses or at a point in time. A performance obligation is satisfied over time if the Company has an enforceable right to payment, including a reasonable profit margin. Determining if an enforceable right to payment includes a reasonable profit margin requires judgment and is assessed on a contract by contract basis.

Table of Contents
Generally, there are no subjective customer acceptance requirements or further obligations related to goods or services provided; if such requirements or obligations exist, then a sale is recognized at the time when such requirements are completed and such obligations are fulfilled.
The Company does not allow for a general right of return. Net sales include amounts billed to customers for shipping and handling and out-of-pocket expenses. The corresponding shipping and handling costs and out-of-pocket expenses are included in cost of sales. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from net sales.
Contract Costs
For contracts requiring over time revenue recognition, the selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company uses a cost-based input measurement of progress because it best depicts the transfer of assets to the customer, which occurs as costs are incurred during the manufacturing process or as services are rendered. Under the cost-based measure of progress, the extent of progress towards completion is measured based on the costs incurred to date. There were no other costs to obtain or fulfill customer contracts.

Contract Balances
The timing of revenue recognition, billings and cash collections results in billed accounts receivable, contract assets, and deferred revenue on the Company’s accompanying Condensed Consolidated Balance Sheets.
Contract Assets: For performance obligations satisfied at a point in time, billing occurs subsequent to revenue recognition, at which point the customer has been billed and the resulting asset is recorded within accounts receivable. For performance obligations satisfied over time as work progresses, the Company has an unconditional right to payment, which results in the recognition of contract assets. The following table summarizes the activity in the Company's contract assets during the six months ended April 3, 2021 and April 4, 2020 (in thousands):

|  | Six Months Ended
|  | April 3, 2021 |  | April 4, 2020
Contract assets, beginning of period |  | $ | 113,946 |  |  | $ | 90,841 |
Revenue recognized during the period |  | 1,559,878 |  |  | 1,460,580 |
Amounts collected or invoiced during the period |  | (1,557,384) |  |  | (1,440,144) |
Contract assets, end of period |  | $ | 116,440 |  |  | $ | 111,277 |

Deferred Revenue: Deferred revenue is recorded when consideration is received from a customer prior to transferring goods or services to the customer under the terms of the contract, which is included in other accrued liabilities on the Condensed Consolidated Balance Sheets. As of April 3, 2021 and October 3, 2020 the balance of advance payments from customers that remained in other accrued liabilities was $60.5 million and $55.6 million, respectively. The advance payment is not considered a significant financing component because it is used to meet working capital demands that can be higher in the early stages of a contract, offset obsolete and excess inventory risks and to protect the Company from the other party failing to adequately complete some or all of its obligations under the contract. Deferred revenue is recognized into revenue when all revenue recognition criteria are met. For performance obligations satisfied over time, recognition will occur as work progresses; otherwise deferred revenue will be recognized based upon shipping terms.
15. Restructuring and Impairment Charges
Restructuring and impairment charges incurred in the Company's EMEA and AMER segments, in the periods presented, primarily relate to the reductions-in-force and the previously announced closure of our Boulder Design Center. These charges are recorded within restructuring and impairment charges on the Condensed Consolidated Statements of Comprehensive Income (Loss). Restructuring liabilities are recorded within other accrued liabilities on the Condensed Consolidated Balance Sheets.
For the three and six months ended April 3, 2021, the Company incurred restructuring and impairment charges of $2.0 million, which consisted of severance from the reduction of the Company's workforce primarily in the EMEA region.
For the three and six months ended April 4, 2020, the Company incurred restructuring and impairment charges of $6.0 million, which consisted of the following:
•$3.1 million of fixed asset and operating right-of-use asset impairment at the Company's Boulder Design Center; and

COVID-19 Update
We continue to monitor the global outbreak and spread of COVID-19 and take steps to mitigate the potential risks to us posed by its spread and related circumstances and impacts.
The health and safety of our employees is a top priority for us. We have progressively implemented measures to safeguard our employees from the COVID-19 infection and exposure and have made significant efforts to mitigate the effects of regulatory authority restrictions on our operations through a combination of adjustments in our shift patterns, flexible work arrangements, productivity improvements, facility enhancements to support social distancing and optimizing employee capability to work from home. These efforts will continue as requirements change, new risks are identified, and infections impact us. We have recently experienced an increase in labor shortages due to COVID-19 quarantines, particularly in Malaysia, as the virus continues to spread. While we have been successful in largely mitigating the effects of the pandemic on our productivity, the continued spread and resurgence of the COVID-19 virus may make our ability to mitigate the impacts more challenging.
We remain in close contact with our suppliers and our customers to understand the impacts of COVID-19 on their businesses and operations. Our suppliers may face challenges in maintaining an adequate workforce or securing materials from their own suppliers as a result of COVID-19. We have experienced, and may continue to experience, an inability to procure certain components and materials on a timely basis as a result of the COVID-19 outbreak. We continue to take steps to validate our suppliers’ ability to deliver to us on time. Our customers have experienced volatility and uncertainty, which has resulted in the need for us to react and respond.
We believe we are positioned with a strong balance sheet as we face the future challenges presented by COVID-19. As of the second quarter of fiscal 2021, cash and cash equivalents and restricted cash were $295 million, while debt, finance lease obligations and other financing were $239 million. Borrowings under our Credit Facility as of April 3, 2021 were $38 million, leaving $312 million of our revolving commitment of $350 million available for use as of April 3, 2021.
See "Risk Factors" contained in our Annual Report on Form 10-K for the fiscal year ended October 3, 2020, "Our financial condition and results of operations may be materially adversely affected by the ongoing coronavirus (COVID-19) outbreak."

Net sales. For the three months ended April 3, 2021, net sales increased $113.5 million, or 14.8%, as compared to the three months ended April 4, 2020. For the six months ended April 3, 2021, net sales increased $91.4 million, or 5.6%, as compared to the six months ended April 4, 2020.
Net sales are analyzed by management by geographic segment, which reflects our reportable segments, and by market sector. Management measures operational performance and allocates resources on a geographic segment basis. Our global business development strategy is based on our targeted market sectors. Beginning in fiscal year 2021, we consolidated the previously reported Industrial/Commercial and Communications market sectors to form the Industrial market sector. Prior period amounts have been reclassified to conform to the current period presentation.
A discussion of net sales by reportable segment is presented below (in millions):

Total net sales |  | $ | 880.9 |  |  | $ | 767.4 |  |  | $ | 1,711.2 |  |  | $ | 1,619.8 |

AMER. Net sales for the three months ended April 3, 2021 in the AMER segment increased $30.3 million, or 9.1%, as compared to the three months ended April 4, 2020. The increase in net sales was driven by a $28.0 million increase in production ramps for new customers, partially inclusive of increased demand as a result of COVID-19, and a $15.7 million increase in production ramps of new products for existing customers. These increases were partially offset by net decreased customer end-market demand, primarily with commercial aerospace customers in the Aerospace/Defense sector.
During the six months ended April 3, 2021, net sales in the AMER segment increased $4.4 million, or 0.6%, as compared to the six months ended April 4, 2020. The increase in net sales was driven by a $48.1 million increase in production ramps for new customers, partially inclusive of increased demand as a result of COVID-19, and a $28.8 million increase in production ramps of new products for existing customers. These increases were mostly offset by net decreased customer end-market demand, primarily with commercial aerospace customers in the Aerospace/Defense sector, and a reduction in net sales of $13.8 million due to disengagements with customers.

Cost of sales. Cost of sales for the three months ended April 3, 2021 increased $84.0 million, or 11.9%, as compared to the three months ended April 4, 2020, while cost of sales for the six months ended April 3, 2021 increased $61.9 million, or 4.2%, as compared to the six months ended April 4, 2020. Cost of sales is comprised primarily of material and component costs, labor costs and overhead. For the three and six months ended April 3, 2021 and April 4, 2020, approximately 89% of the total cost of sales was variable in nature and fluctuated with sales volumes. Of these amounts, approximately 88% of these costs for the three and six months ended April 3, 2021, 86% for the three months ended April 4, 2020 and 87% for the six months ended April 4, 2020, were related to material and component costs.
The increase in cost of sales for the three and six months ended April 3, 2021 compared to the three and six months ended April 4, 2020 was primarily driven by the increase in net sales and an increase in fixed costs. These increases were partially offset by an improvement in labor productivity, a decrease in employee compensation and supplies costs associated with COVID-19, and a decrease in travel and healthcare costs.
Gross profit. Gross profit for the three months ended April 3, 2021 increased $29.6 million, or 48.2%, as compared to the three months ended April 4, 2020. Gross profit for the six months ended April 3, 2021 increased $29.7 million, or 21.1%, as compared to the six months ended April 4, 2020. Gross margin of 10.3% for the three months ended April 3, 2021 increased 230 basis points while gross margin of 10.0% for the six months ended April 3, 2021 increased 130 basis points as compared to the three and six months ended April 4, 2020, respectively. The primary reasons for the increase in gross margin for the three and six months ended April 3, 2021 were the improvements in labor productivity, as well as a decrease in travel and healthcare costs.
Operating income. Operating income for the three months ended April 3, 2021 increased $33.5 million, or 194.8%, as compared to the three months ended April 4, 2020 as a result of the increase in gross profit and a decrease in selling and administrative expenses ("S&A"). The decrease in S&A was primarily due to the decrease in restructuring and impairment charges, a decrease in bad debt expense, and a decrease in travel and healthcare costs. This was partially offset by an increase in incentive compensation expenses. Operating margin of 5.8% increased 360 basis points compared to the three months ended April 4, 2020 primarily due to the increase in gross margin as a result of factors previously discussed and reduction of S&A.
Operating income for the six months ended April 3, 2021 increased $40.5 million, or 70.9%, as compared to the six months ended April 4, 2020 as a result of the increase in gross profit and a decrease in S&A. The decrease in S&A was primarily due to a decrease in bad debt expense, a decrease in restructuring and impairment charges, and a decrease in travel and healthcare costs. This was partially offset by an increase in incentive compensation expenses. Operating margin of 5.7% increased 220 basis points compared to the six months ended April 4, 2020 primarily due to the increase in gross margin as a result of factors previously discussed and reduction of S&A.

|  | April 3, 2021 |  | April 4, 2020 |  | April 3, 2021 |  | April 4, 2020
Income tax expense, as reported (GAAP) |  | $ | 4.7 |  |  | $ | 1.2 |  |  | $ | 10.1 |  |  | $ | 4.4 |
Restructuring and impairment charges |  | 0.2 |  |  | 0.6 |  |  | 0.2 |  |  | 0.6 |

Effective tax rate, as reported (GAAP) |  | 10.1 | % |  | 8.2 | % |  | 11.5 | % |  | 9.1 | %
Restructuring and impairment charges |  | — |  |  | 0.7 |  |  | — |  |  | 0.8 |
Impact of other special tax items |  | — |  |  | — |  |  | — |  |  | 0.9 |
Effective tax rate, as adjusted (non-GAAP) (1) |  | 10.1 | % |  | 8.9 | % |  | 11.5 | % |  | 10.8 | %

(1) We believe the non-GAAP presentation of income tax expense and the effective tax rate excluding special tax items, guidance issued by the U.S. Department of the Treasury and restructuring charges provides additional insight over the change from the comparative reporting periods by isolating the impact of these significant, special items. In addition, we believe that our income tax expense, as adjusted, and effective tax rate, as adjusted, enhance the ability of investors to analyze our operating performance and supplement, but do not replace, our income tax expense and effective tax rate calculated in accordance with U.S. GAAP.
Income tax expense for the three and six months ended April 3, 2021 was $4.7 million and $10.1 million, respectively, compared to $1.2 million and $4.4 million for the three and six months ended April 4, 2020, respectively. The increase is primarily due to an increase in pre-tax book income for the three and six months ended April 3, 2021. The increase is partially offset by a tax benefit of $0.9 million recognized for the three months ended April 3, 2021 related to the release of a full valuation allowance for a jurisdiction within the EMEA segment related to a settlement of an income tax audit. In addition, there was a net $0.8 million benefit for special tax items during the six months ended April 4, 2020.
Our annual effective tax rate varies from the U.S. statutory rate of 21.0% primarily due to the geographic distribution of worldwide earnings as well as a tax holiday granted to a subsidiary located in the APAC segment where we derive a significant

portion of our earnings. Our effective tax rate also may be impacted by disputes with taxing authorities, tax planning activities, adjustments to uncertain tax positions and changes in valuation allowances.
The estimated effective income tax rate for fiscal 2021 is expected to be approximately 12.0% to 14.0%.
Net Income. Net income for the three months ended April 3, 2021 increased $28.9 million, or 224.0%, from the three months ended April 4, 2020 to $41.8 million. Net income increased primarily as a result of the increase in operating income, partially offset by the increase in income tax expense as previously discussed.
Net income for the six months ended April 3, 2021 increased $34.1 million, or 77.7%, from the six months ended April 4, 2020 to $78.0 million. Net income increased primarily as a result of the increase in operating income, partially offset by the increase in income tax expense as previously discussed.
Diluted earnings per share. Diluted earnings per share for the three months ended April 3, 2021 increased to $1.42 from $0.43 for the three months ended April 4, 2020, primarily as a result of increased net income due to the factors discussed above and a reduction in diluted shares outstanding due to repurchase activity under the Company's stock repurchase plans.
Diluted earnings per share for the six months ended April 3, 2021 increased to $2.65 from $1.46 for the six months ended April 4, 2020, primarily as a result of increased net income due to the factors discussed above and a reduction in diluted shares outstanding due to repurchase activity under the Company's stock repurchase plans.
Return on Invested Capital ("ROIC") and economic return. We use a financial model that is aligned with our business strategy and includes a ROIC goal of 500 basis points over our weighted average cost of capital ("WACC"), which we refer to as "economic return."
Non-GAAP financial measures, including ROIC and economic return, are used for internal management goals and decision making because such measures provide management and investors additional insight into financial performance. In particular, we provide ROIC and economic return because we believe they offer insight into the metrics that are driving management decisions because we view ROIC and economic return as important measures in evaluating the efficiency and effectiveness of our long-term capital requirements. We also use a derivative measure of ROIC as a performance criteria in determining certain elements of compensation, and certain compensation incentives are based on economic return performance.
We define ROIC as tax-effected operating income before restructuring and other special items divided by average invested capital over a rolling three-quarter period for the second quarter. Invested capital is defined as equity plus debt and operating lease liabilities, less cash and cash equivalents. Other companies may not define or calculate ROIC in the same way. ROIC and other non-GAAP financial measures should be considered in addition to, not as a substitute for, measures of our financial performance prepared in accordance with U.S. generally accepted accounting principles ("GAAP").
We review our internal calculation of WACC annually. Our WACC was 8.1% for fiscal year 2021 and 8.8% for fiscal year 2020. By exercising discipline to generate ROIC in excess of our WACC, our goal is to create value for our shareholders. For the six months ended April 3, 2021, ROIC of 17.3% reflects an economic return of 9.2%, based on our weighted average cost of capital of 8.1%. For the six months ended April 4, 2020, ROIC of 11.4% reflects an economic return of 2.6%, based on our weighted average cost of capital of 8.8% for that fiscal year.
For a reconciliation of ROIC, economic return and adjusted operating income (tax effected) to our financial statements that were prepared using GAAP, see Exhibit 99.1 to this quarterly report on Form 10-Q, which exhibit is incorporated herein by reference.
Refer to the table below, which includes the calculation of ROIC and economic return (dollars in millions) for the indicated periods:

|  | Six Months Ended
|  | April 3, 2021 |  | April 4, 2020
Adjusted operating income (tax effected) |  | $ | 173.3 |  |  | $ | 109.9 |
Average invested capital |  | 1,002.3 |  |  | 964.9 |
ROIC |  | 17.3 | % |  | 11.4 | %
WACC |  | 8.1 | % |  | 8.8 | %
Economic return |  | 9.2 | % |  | 2.6 | %

LIQUIDITY AND CAPITAL RESOURCES
Cash and cash equivalents and restricted cash were $294.5 million as of April 3, 2021, as compared to $387.9 million as of October 3, 2020.
As of April 3, 2021, 88% of our cash and cash equivalents balance was held outside of the U.S. by our foreign subsidiaries. Currently, we believe that our cash balance, together with cash available under our Credit Facility, will be sufficient to meet our liquidity needs and potential share repurchases, if any, for the next twelve months and for the foreseeable future.
Our future cash flows from operating activities will be reduced by $53.6 million due to cash payments for U.S. federal taxes on the deemed repatriation of undistributed foreign earnings that are payable over an eight year period that began in fiscal 2019 with the first payment. The table below provides the expected timing of these future cash outflows, in accordance with the following installment schedule for the remaining six years (in millions):

Remaining 2021 | $ | — |
2022 | 5.6 |
2023 | 5.6 |
2024 | 10.6 |
2025 | 14.2 |
2026 | 17.6 |
Total | $ | 53.6 |

Cash Flows. The following table provides a summary of cash flows (in millions):

|  | Six Months Ended
|  | April 3, 2021 |  | April 4, 2020
Cash provided by operating activities |  | $ | 88.9 |  |  | $ | 45.4 |
Cash used in investing activities |  | (23.1) |  |  | (30.0) |
Cash used in financing activities |  | (160.5) |  |  | (14.3) |

Operating Activities. Cash flows provided by operating activities were $88.9 million for the six months ended April 3, 2021, as compared to $45.4 million for the six months ended April 4, 2020. The increase was primarily due to the increase in net income, as well as cash flow improvements (reductions) of:
•$61.0 million in inventory cash flows driven by inventory management efforts, as well as stabilizing inventory levels for the six months ended April 3, 2021 compared to the six months ended April 4, 2020. For the six months ended April 4, 2020, we had increasing inventory levels to support the ramp of customer programs and longer lead times for certain components due to the COVID-19 outbreak.
•$17.9 million in contract asset cash flows driven by consistent demand from over time customers compared to growing demand in the six months ended April 4, 2020.
•$17.3 million in customer deposit cash flows driven by significant deposits received from three customers offset by a significant deposit reduction from one customer in the current year.
•$(43.6) million in accounts receivable cash flows, which resulted from the increase in net sales.
•$(25.3) million in accounts payables cash flows driven by decreased purchasing activity as prior purchasing activity provided sufficient inventory to meet current demand.
•$(18.5) million in other current and noncurrent asset cash flows driven by an increase in prepaid expenses and miscellaneous receivables.

The following table provides a summary of cash cycle days for the periods indicated (in days):

|  | Three Months Ended
|  | April 3, 2021 |  | April 4, 2020
Days in accounts receivable |  | 52 |  | 55
Days in contract assets |  | 12 |  | 13
Days in inventory |  | 89 |  | 99
Days in accounts payable |  | (61) |  | (62)
Days in cash deposits |  | (20) |  | (18)
Annualized cash cycle |  | 72 |  | 87

We calculate days in accounts receivable and contract assets as each balance sheet item for the respective quarter divided by annualized sales for the respective quarter by day. We calculate days in inventory, accounts payable, and cash deposits as each balance sheet line item for the respective quarter divided by annualized cost of sales for the respective quarter by day. We calculate annualized cash cycle as the sum of days in accounts receivable, days in contract assets and days in inventory, less days in accounts payable and days in cash deposits.
As of April 3, 2021, annualized cash cycle days decreased fifteen days compared to the three months ended April 4, 2020 due to the following factors:
Days in accounts receivable for the three months ended April 3, 2021 decreased three days compared to the three months ended April 4, 2020. The decrease is primarily attributable to the timing of customer shipments and payments and mix of customer payment terms.
Days in contract assets for the three months ended April 3, 2021 decreased one day compared to the three months ended April 4, 2020. The decrease is primarily attributable to increased net sales.
Days in inventory for the three months ended April 3, 2021 decreased ten days compared to the three months ended April 4, 2020. The decrease is primarily attributable to increased net sales and continued inventory management.
Days in accounts payable for the three months ended April 3, 2021 decreased one day compared to the three months ended April 4, 2020. The decrease is primarily attributable to decreased purchasing activity as prior purchasing activity provided sufficient inventory to meet current demand.
Days in cash deposits for the three months ended April 3, 2021 increased two days compared to the three months ended April 4, 2020. The increase was primarily attributable to significant deposits received from three customers to cover higher inventory balances.
Free Cash Flow. We define free cash flow ("FCF"), a non-GAAP financial measure, as cash flow provided by operations less capital expenditures. FCF was $65.7 million for the six months ended April 3, 2021 compared to $14.7 million for the six months ended April 4, 2020, an increase of $51.0 million.
Non-GAAP financial measures, including FCF, are used for internal management assessments because such measures provide additional insight to investors into ongoing financial performance. In particular, we provide FCF because we believe it offers insight into the metrics that are driving management decisions. We view FCF as an important financial metric as it demonstrates our ability to generate cash and can allow us to pursue opportunities that enhance shareholder value. FCF is a non-GAAP financial measure that should be considered in addition to, not as a substitute for, measures of our financial performance prepared in accordance with GAAP.
A reconciliation of FCF to our financial statements that were prepared using GAAP follows (in millions):

|  | Six Months Ended
|  | April 3, 2021 |  | April 4, 2020
Cash flows provided by operating activities |  | $ | 88.9 |  |  | $ | 45.4 |
Payments for property, plant and equipment |  | (23.2) |  |  | (30.7) |
Free cash flow |  | $ | 65.7 |  |  | $ | 14.7 |

Investing Activities. Cash flows used in investing activities were $23.1 million for the six months ended April 3, 2021 compared to $30.0 million for the six months ended April 4, 2020. The decrease in cash used in investing activities was due to a $7.5 million decrease in capital expenditures, primarily due to the construction of a second manufacturing facility in Guadalajara during the six months ended April 4, 2020.
We estimate funded capital expenditures for fiscal 2021 will be approximately $70.0 million to $85.0 million, of which $23.2 million was utilized through the first six months of fiscal 2021. The remaining fiscal 2021 capital expenditures are anticipated to be used primarily for our manufacturing footprint expansion in Thailand and to support new program ramps as well as to replace older equipment. We believe our estimated capital expenditures will continue to be funded from cash flows provided by operations and may be supplemented by available cash or borrowings, if required.
Financing Activities. Cash flows used in financing activities were $160.5 million for the six months ended April 3, 2021 compared to $14.3 million for the six months ended April 4, 2020. The increase was primarily attributable to the repayment of the $138 million term loan, an increase of $32.4 million in cash used to repurchase our common stock and a $6.5 million decrease in proceeds from the exercise of stock options. This was partially offset by an increase of $32.0 million in net borrowings on our revolving commitment from the six months ended April 4, 2020.
On August 20, 2019, the Board of Directors approved a share repurchase plan under which we are authorized to repurchase $50.0 million of our common stock (the "2019 Program"). During the three months ended January 2, 2021, we completed the 2019 Program by repurchasing 73,560 shares under this program for $5.3 million at an average price of $72.44 per share. During the three months ended April 4, 2020, we repurchased 224,564 shares under this program for $13.2 million at an average price of $58.57 per share. During the six months ended April 4, 2020, we repurchased 315,231 shares under this program for $19.5 million at an average price of $61.81.
On August 13, 2020, the Board of Directors approved a new share repurchase program that authorizes us to repurchase up to $50.0 million of our common stock (the "2021 Program") beginning on expiration of the 2019 program. On November 18, 2020, the Board of Directors approved an additiona l $50.0 million in share repurchase authority under the existing 2021 Program such that there now exists a total of $100.0 million in share repurchase authority under the program. During the three months ended April 3, 2021, we repurchased 349,297 shares under this program for $29.1 million at an average price of $83.39 per share. During the six months ended April 3, 2021, we repurchased 582,808 shares under this program for $46.6 million at an average price of $79.91. As of April 3, 2021, $53.4 million of authority remained under the 2021 program. The 2021 Program has no expiration.
All shares repurchased under the aforementioned programs were recorded as treasury stock.
On June 15, 2018, we entered into a Note Purchase Agreement (the “2018 NPA”) pursuant to which it issued an aggregate of $150.0 million in principal amount of unsecured senior notes, consisting of $100.0 million in principal amount of 4.05% Series A Senior Notes, due on June 15, 2025, and $50.0 million in principal amount of 4.22% Series B Senior Notes, due on June 15, 2028 (collectively, the “2018 Notes”), in a private placement. The 2018 NPA includes customary operational and financial covenants with which we are required to comply, including, among others, maintenance of certain financial ratios such as a total leverage ratio and a minimum interest coverage ratio. The 2018 Notes may be prepaid in whole or in part at any time, subject to payment of a make-whole amount; interest on the 2018 Notes is payable semiannually. As of April 3, 2021, we were in compliance with the covenants under the 2018 NPA.
On May 15, 2019, we refinanced our then-existing senior unsecured revolving credit facility by entering into a new five-year senior unsecured revolving credit facility (referred to as the "Credit Facility"), which expanded the maximum commitment from $300.0 million to $350.0 million and extended the maturity from July 5, 2021 to May 15, 2024. The maximum commitment under the Credit Facility may be further increased to $600.0 million, generally by mutual agreement of the lenders and us, subject to certain customary conditions. During the six months ended April 3, 2021, the highest daily borrowing was $148.0 million; the average daily borrowings were $48.2 million. We borrowed $151.0 million and repaid $113.0 million of revolving borrowings under the Credit Facility during the six months ended April 3, 2021. As of April 3, 2021, we were in compliance with all financial covenants relating to the Credit Agreement, which are generally consistent with those in the 2018 NPA discussed above. We are required to pay a commitment fee on the daily unused revolver credit commitment based on our leverage ratio; the fee was 0.125% as of April 3, 2021.
To further ensure our ability to meet our working capital and fixed capital requirements, on April 29, 2020, we entered into Amendment No. 1 to the Credit Agreement (the "Amendment") in response to the COVID-19 outbreak, which amended the Credit Agreement, dated as of May 15, 2019. The Amendment modified certain provisions of the Credit Facility to, among other things, provide for a 364 day unsecured delayed draw term loans ("Term Loans") for $138.0 million. Term Loans borrowed under the new facility were funded in a single draw on May 4, 2020 and were scheduled to mature on April 28, 2021. On January 29, 2021, we terminated the Term Loans through repayment of the $138.0 million outstanding using borrowings

from our revolving commitment under the Credit Facility. Outstanding Term Loans bore interest, at our option, at a eurocurrency rate (subject to a floor of 1.0%) plus a margin of 1.75% per annum or at a base rate (subject to a floor of 2.0%) plus a margin of 0.75% per annum.
The Credit Agreement and the 2018 NPA allow for the future payment of cash dividends or the repurchase of shares provided that no event of default (including any failure to comply with a financial covenant) exists at the time of, or would be caused by, the dividend payment or the share repurchases. We have not paid cash dividends in the past. However, we evaluate from time to time potential uses of excess cash, which in the future may include share repurchases above those already authorized, a special cash dividend or recurring cash dividends.
We have Master Accounts Receivable Purchase Agreements with MUFG Bank, New York Branch (formerly known as The Bank of Tokyo-Mitsubishi UFJ, Ltd.) (the "MUFG RPA"), and HSBC Bank (China) Company Limited, Xiamen branch (the "HSBC RPA"), under which we may elect to sell receivables, at a discount, on an ongoing basis. These facilities are uncommitted facilities. The maximum facility amount under the MUFG RPA as of April 3, 2021 is $340.0 million. The maximum facility amount under the HSBC RPA as of April 3, 2021 is $60.0 million. The MUFG RPA will be automatically extended each year unless any party gives no less than 10 days prior notice that the agreement should not be extended. The contract length terms of the HSBC RPA are generally consistent with the terms of the MUFG RPA discussed above.
We sold $195.6 million and $188.3 million of trade accounts receivable under these programs during the three months ended April 3, 2021 and April 4, 2020, respectively, in exchange for cash proceeds of $195.1 million and $187.4 million, respectively.
The Company sold $394.0 million and $416.1 million of trade accounts receivable under these programs, or their predecessors, during the six months ended April 3, 2021 and April 4, 2020, respectively, in exchange for cash proceeds of $392.9 million and $414.0 million, respectively.
In all cases, the sale discount was recorded within "Miscellaneous, net" in the Condensed Consolidated Statements of Comprehensive Income (Loss) in the period of the sale. For further information regarding the receivable sale programs, see Note 13, "Trade Accounts Receivable Sale Programs," in Notes to Condensed Consolidated Financial Statements.
Based on current expectations, we believe that our projected cash flows provided by operations, available cash and cash equivalents, potential borrowings under the Credit Facility and our leasing capabilities should be sufficient to meet our working capital and fixed capital requirements for the next twelve months. We believe we are positioned with a strong balance sheet as we face the future challenges that may be presented by COVID-19. As of the end of the second quarter of fiscal 2021, cash and cash equivalents and restricted cash were $295 million, while debt, finance lease obligations and other financing were $239 million. In addition to our strong balance sheet, we have significant funding availability through our Credit Facility, should future needs arise. If our future financing needs increase, then we may need to arrange additional debt or equity financing. Accordingly, we evaluate and consider from time to time various financing alternatives to supplement our financial resources. However, we cannot be assured that we will be able to make any such arrangements on acceptable terms.

DISCLOSURE ABOUT CRITICAL ACCOUNTING POLICIES
Our critical accounting policies are disclosed in our 2020 Annual Report on Form 10-K. During the second quarter of fiscal 2021, there were no material changes.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposed to market risk from changes in foreign exchange and interest rates. We selectively use financial instruments to reduce such risks. We do not use derivative financial instruments for speculative purposes.
Foreign Currency Risk
Our international operations create potential foreign exchange risk. Our policy is to selectively hedge our foreign currency denominated transactions in a manner that partially offsets the effects of changes in foreign currency exchange rates. We typically use foreign currency contracts to hedge only those currency exposures associated with certain assets and liabilities denominated in non-functional currencies. Corresponding gains and losses on the underlying transaction generally offset the gains and losses on these foreign currency hedges. We cannot predict changes in currency rates, nor the degree to which we will be able to manage the impacts of currency exchange rate changes, including the impacts on currency exchange rates related to the COVID-19 outbreak.
Our percentages of transactions denominated in currencies other than the U.S. dollar for the indicated periods were as follows:

|  | Three Months Ended
|  | April 3, 2021 |  | April 4, 2020
Net Sales |  | 10.4% |  | 11.0%
Total Costs |  | 15.2% |  | 15.7%

We have evaluated the potential foreign currency exchange rate risk on transactions denominated in currencies other than the U.S. dollar for the periods presented above. Based on our overall currency exposure, as of April 3, 2021, a 10.0% change in the value of the U.S. dollar relative to our other transactional currencies would not have a material effect on our financial position, results of operations, or cash flows.
Interest Rate Risk
We have financial instruments, including debt, which are sensitive to changes in interest rates. The primary objective of our investment activities is to preserve principal, while maximizing yields without significantly increasing market risk. To achieve this, we limit the amount of principal exposure to any one issuer. We cannot predict changes in interest rates, including the impacts on interest rates related to the COVID-19 outbreak.
As of April 3, 2021, our only material interest rate risk is associated with our Credit Facility. Revolving commitments under the Credit Facility bear interest, at our option, at a eurocurrency or base rate plus, in each case, an applicable interest rate margin based on our then-current leverage ratio (as defined in the Credit Agreement). As of April 3, 2021, the borrowing rate under the Credit Agreement was LIBOR plus 1.10%. Borrowings under the 2018 NPA are based on a fixed interest rate, thus mitigating much of our interest rate risk. Based on our overall interest rate exposure, as of April 3, 2021, a 10.0% change in interest rates would not have a material effect on our financial position, results of operations, or cash flows.

ITEM 4. CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
The Company maintains disclosure controls and procedures designed to ensure that the information the Company must disclose in its filings with the Securities and Exchange Commission ("SEC") is recorded, processed, summarized and reported on a timely basis. The Company’s Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO") have reviewed and evaluated, with the participation of the Company’s management, the Company’s disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act") as of the end of the period covered by this report (the "Evaluation Date"). Based on such evaluation, the CEO and CFO have concluded that, as of the Evaluation Date, the Company’s disclosure controls and procedures are effective, at the reasonable assurance level, (a) in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by the Company in the reports the Company files or submits under the Exchange Act, and (b) in assuring that information is accumulated and communicated to the Company’s management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control Over Financial Reporting
During the second quarter of fiscal 2021, there have been no changes in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

ITEM 1A. Risk Factors
In addition to the risks and uncertainties discussed herein, particularly those discussed in the “Safe Harbor” Cautionary Statement and "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in Part I, Item 2, see the risk factors set forth in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended October 3, 2020 that have had no material changes.
ITEM 2. Unregistered Sales of Equity Securities and Use of Proceeds
The following table provides the specified information about the repurchases of shares by the Company during the three months ended April 3, 2021.

(1) On August 13, 2020, the Board of Directors approved a new stock repurchase plan under which we are authorized to repurchase up to $50.0 million of our common stock (the "2021 Program").
