NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
Note 1 — Basis of Presentation and New Accounting Pronouncements
Basis of Presentation
The accompanying condensed consolidated financial information of FormFactor, Inc. is unaudited and has been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). However, such information reflects all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods. The condensed consolidated financial statements included herein should be read in conjunction with the consolidated financial statements and the notes thereto included in our 2020 Annual Report on Form 10-K filed with the SEC on February 22, 2021. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the full year.
Fiscal Year
We operate on a 52/53 week fiscal year, whereby the fiscal year ends on the last Saturday of December. Fiscal 2021 and 2020 each contain 52 weeks and the nine months ended September 25, 2021 and September 26, 2020 each contained 39 weeks. Fiscal 2021 will end on December 25, 2021.
Significant Accounting Policies
Our significant accounting policies have not changed during the nine months ended September 25, 2021 from those disclosed in our Annual Report on Form 10-K for the year ended December 26, 2020.
New Accounting Pronouncements
ASU 2019-12
In December 2019, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, “Income Taxes (Topic 740),” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. We adopted ASU 2019-12 on a prospective basis on December 27, 2020, the first day of fiscal 2021. The adoption did not have a material effect on our consolidated financial position, results of operations or cash flows.
ASU 2020-04
In March 2020, the FASB issued ASU 2020-04, “Referenced Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The ASU provides temporary optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848),” which permits entities to apply optional expedients in Topic 848 to derivative instruments modified because of discounting transition resulting from reference rate reform. ASU 2020-04 became effective upon issuance and may be applied prospectively to contract modifications made on or before December 31, 2022. ASU 2021-01 became effective upon issuance and may be applied on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020 or prospectively for contract modifications made on or before December 31, 2022. The Company has not yet applied the relief afforded by these standard amendments and is currently assessing contracts that will require modification due to reference rate reform to which these standard amendments may be applied.

High Precision Devices, Inc. Acquisition
On October 19, 2020, we acquired HPD for total consideration of $16.9 million, net of cash acquired of $1.7 million, which included an adjustment for changes in working capital.

The acquisition price was allocated to the tangible and identified intangible assets acquired and liabilities assumed as of the closing date of the acquisition based upon their respective fair values, including an amount for goodwill representing the difference between the acquisition consideration and the fair value of the identifiable net assets. The fair values assigned to the assets acquired and liabilities assumed were based on management’s assumptions as of the acquisition date. We subsequently made certain immaterial adjustments within the measurement period to the acquisition price allocation as a result of finalization of our valuation of identifiable assets and liabilities. See Note 5, Goodwill and Intangible Assets, for the changes

Note 7 — Restructuring Charges
On September 25, 2021, we adopted restructuring plans to improve our business effectiveness and streamline our operations by consolidating certain manufacturing facilities for both the Probe Cards segment and the Systems segment. This includes plans to consolidate or relocate certain leased locations in the United States to other locations in the United States, Germany and Asia. As a result of these changes to certain work locations, we have incurred, and expect to incur, personnel related costs to sever, relocate, or retain select employees. Additionally, we are undertaking actions to adjust capacity for certain product offerings. As a result of these adjustments, contract termination costs include charges to satisfy contract obligations. The liability was recognized using our best estimate and it is reasonably possible that the final amount will differ from the amount estimated in the near term. We expect the actions defined under these plans will be largely completed by the end of December 2022, except facilities charges which may extend beyond that time.
This plan is expected to result in FormFactor recording restructuring and other charges in the aggregate amount of approximately $8.0 million to $10.5 million, estimated to be comprised primarily of $1.0 million to $2.0 million of severance and employee-related costs, $3.5 million to 4.5 million in contract and lease termination costs, $1.0 million to $1.5 million in inventory impairments, and $2.0 million to $2.5 million of cost related to impairment of leasehold improvements, facility exits, and other costs. Approximately $5.0 million to $6.0 million and $3.0 million to $4.5 million is expected within the Probe Cards segment and Systems segment, respectively.

Note 8 — Fair Value and Derivative Instruments
Whenever possible, the fair values of our financial assets and liabilities are determined using quoted market prices of identical securities or quoted market prices of similar securities from active markets. The three levels of inputs that may be used to measure fair value are as follows:
•Level 1 valuations are obtained from real-time quotes for transactions in active exchange markets involving identical securities;
•Level 2 valuations utilize significant observable inputs, such as quoted prices for similar assets or liabilities, quoted prices near the reporting date in markets that are less active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and
•Level 3 valuations utilize unobservable inputs to the valuation methodology and include our own data about assumptions market participants would use in pricing the asset or liability based on the best information available under the circumstances.
We did not have any transfers of assets or liabilities measured at fair value on a recurring basis to or from Level 1, Level 2 or Level 3 during the three and nine months ended September 25, 2021 or the year ended December 26, 2020.
15

The carrying values of Cash, Accounts receivable, net, Restricted cash, Prepaid expenses and other current assets, Accounts payable, Accrued liabilities, and term loans, net of unamortized issuance costs, approximate fair value due to their short maturities.
No changes were made to our valuation techniques during the first nine months of fiscal 2021.

Cash Equivalents
The fair value of our cash equivalents is determined based on quoted market prices for similar or identical securities.
Marketable Securities
We classify our marketable securities as available-for-sale and value them utilizing a market approach. Our investments are
16

priced by pricing vendors who provide observable inputs for their pricing without applying significant judgment. Broker pricing is used mainly when a quoted price is not available, the investment is not priced by our pricing vendors or when a broker price is more reflective of fair value. Our broker-priced investments are categorized as Level 2 investments because fair value is based on similar assets without applying significant judgments. In addition, all investments have a sufficient trading volume to demonstrate that the fair value is appropriate.
Unrealized gains and losses were immaterial and were recorded as a component of Accumulated other comprehensive income in our Condensed Consolidated Balance Sheets. We did not have any other-than-temporary unrealized gains or losses at either period end included in these financial statements.
Contingent Consideration
Contingent consideration, arising from the acquisition of FRT GmbH, was a cash amount equal to 1.5x EBIT as defined in the purchase agreement, up to a maximum of €10.3 million, payable subject to the performance of the acquired business in calendar 2020. We estimated the fair value of contingent consideration using a probability weighted approach. Key assumptions in determining the fair value of contingent consideration included estimating EBIT levels that we believed as of the acquisition date were likely to be achieved during the performance period and discounting at an appropriate discount rate. We settled our contingent consideration in the second quarter of fiscal 2021 for $3.9 million, resulting in a $0.1 million credit to Selling, general and administrative expense with the remaining change from December 26, 2020 resulting from foreign currency translation.
Interest Rate Swaps
The fair value of our interest rate swap contracts is determined at the end of each reporting period based on valuation models that use interest rate yield curves as inputs. For accounting purposes, our interest rate swap contracts qualify for, and are designated as, cash flow hedges. The cash flows associated with the interest rate swaps are reported in Net cash provided by operating activities in our Condensed Consolidated Statements of Cash Flows and the fair value of the interest rate swap contracts are recorded within Accrued liabilities and Other assets in our Condensed Consolidated Balance Sheets.
Foreign Exchange Derivative Contracts
We operate and sell our products in various global markets. As a result, we are exposed to changes in foreign currency exchange rates. We utilize foreign currency forward contracts to hedge against future movements in foreign exchange rates that affect certain existing foreign currency denominated assets and liabilities and forecasted foreign currency revenue and expense transactions. Under this program, our strategy is to have increases or decreases in our foreign currency exposures mitigated by gains or losses on the foreign currency forward contracts in order to mitigate the risks and volatility associated with foreign currency transaction gains or losses.
We do not use derivative financial instruments for speculative or trading purposes. For accounting purposes, certain of our foreign currency forward contracts are not designated as hedging instruments and, accordingly, we record the fair value of these contracts as of the end of our reporting period in our Condensed Consolidated Balance Sheets with changes in fair value recorded within Other expense, net in our Condensed Consolidated Statement of Income for both realized and unrealized gains and losses. Certain of our foreign currency forward contracts are designated as cash flow hedges, and, accordingly, we record the fair value of these contracts as of the end of our reporting period in our Condensed Consolidated Balance Sheets with changes in fair value recorded as a component of Accumulated other comprehensive income and reclassified into earnings in the same period in which the hedged transaction affects earnings, and in the same line item on the Condensed Consolidated Statements of Income as the impact of the hedge transaction.
The fair value of our foreign exchange derivative contracts was determined based on current foreign currency exchange rates and forward points. All of our foreign exchange derivative contracts outstanding at September 25, 2021 will mature by the third quarter of fiscal 2022.
17

The following table provides information about our foreign currency forward contracts outstanding as of September 25, 2021 (in thousands):

Currency |  | Contract Position |  | Contract Amount (Local Currency) |  | Contract Amount (U.S. Dollars)
Euro Dollar |  | Buy |  | (11,900) |  |  | $ | (14,245) |
Euro Dollar |  | Sell |  | 2,520 |  |  | 2,953 |
Japanese Yen |  | Sell |  | 1,992,865 |  |  | 17,994 |
Korean Won |  | Buy |  | (2,513,139) |  |  | (2,138) |
Taiwan Dollar |  | Sell |  | 7,440 |  |  | 269 |
Total USD notional amount of outstanding foreign exchange contracts |  |  |  |  |  | $ | 4,833 |

Our foreign currency contracts are classified within Level 2 of the fair value hierarchy as they are valued using pricing models that utilize observable market inputs.
Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis
We measure and report our non-financial assets such as Property, plant and equipment, Goodwill and Intangible assets at fair value on a non-recurring basis if we determine these assets to be impaired or in the period when we make a business acquisition. Other than as discussed in Note 4, Acquisition, and Note 7, Restructuring, there were no assets or liabilities measured at fair value on a nonrecurring basis during the three and nine months ended September 25, 2021 or September 26, 2020.
Note 9 — Warranty
We offer warranties on certain products and record a liability for the estimated future costs associated with warranty claims at the time revenue is recognized. The warranty liability is based upon historical experience and our estimate of the level of future costs. While we engage in product quality programs and processes, our warranty obligation is affected by product failure rates, material usage and service delivery costs. We continuously monitor product returns for warranty and maintain a reserve for the related expenses based upon our historical experience and any specifically identified failures. As we sell new products to our customers, we must exercise considerable judgment in estimating the expected failure rates. This estimating process is based on historical experience of similar products, as well as various other assumptions that we believe to be reasonable under the circumstances. We provide for the estimated cost of product warranties at the time revenue is recognized as a component of Cost of revenues in our Condensed Consolidated Statement of Income.

Note 11 — Stockholders’ Equity and Stock-Based Compensation
Common Stock Repurchase Program
On October 26, 2020, our Board of Directors authorized a program to repurchase up to $50 million of outstanding common stock to offset potential dilution from issuances of common stock under our stock-based compensation plans. The share repurchase program will expire on October 28, 2022. During the nine months ended September 25, 2021, we repurchased and retired 620,200 shares of common stock for $24.0 million and, as of September 25, 2021, $26.0 million remained available for future repurchases.
Our policy related to repurchases of our common stock is to charge the excess of cost over par value to additional paid-in capital once the shares are retired. All repurchases were made in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended.
Restricted Stock Units
Restricted stock unit (“RSU”) activity under our equity incentive plan was as follows:

RSUs at September 25, 2021 | 2,375,325 |  |  | 28.55 |

Performance Restricted Stock Units
We may grant Performance RSUs (“PRSUs”) to certain executives, which vest based upon us achieving certain market performance criteria.
On August 2, 2021, we granted 197,128 PRSUs to certain senior executives for a total grant date fair value of $8.6 million, which will be recognized ratably over the requisite service period. The performance criteria are based on Total Shareholder Returns ("TSR") for the period of July 1, 2021 - June 30, 2024, relative to the TSR of the companies identified as being part of the S&P semiconductor Select Industry Index (FormFactor peer companies) as of the grant date.
All 318,100 PRSUs granted in fiscal 2018 vested during the nine months ended September 25, 2021. These shares achieved TSR performance that resulted in an additional 124,600 shares issued during the nine months ended September 25, 2021 related to the 2018 PRSU grant.

Legal Matters
From time to time, we may be subject to legal proceedings and claims in the ordinary course of business. As of September 25, 2021, and as of the filing of this Quarterly Report on Form 10-Q, we were not involved in any material legal proceedings.
Note 14 — Leases
We lease real estate space under non-cancelable operating lease agreements for commercial and industrial space, as well as for our corporate headquarters located in Livermore, California. Our leases have remaining terms of 1 to 7 years, and some leases include options to extend up to 20 years. We also have operating leases for automobiles with remaining lease terms of 1 to 4 years. We did not include any of our renewal options in our lease terms for calculating our lease liability as the renewal options allow us to maintain operational flexibility and we are not reasonably certain we will exercise these options at this time. The weighted-average remaining lease term for our operating leases was 6 years as of September 25, 2021 and the weighted-average discount rate was 3.72%.

Note 15 — Revenue
Transaction price allocated to the remaining performance obligations: On September 25, 2021, we had $10.0 million of remaining performance obligations, which were comprised of deferred service contracts and extended warranty contracts and contracts with overtime revenue recognition that are not yet delivered. We expect to recognize approximately 27.9% of our remaining performance obligations as revenue in the remainder of fiscal 2021, approximately 55.8% in fiscal 2022, and approximately 16.3% in fiscal 2023 and thereafter. The foregoing excludes the value of other remaining performance obligations as they have original durations of one year or less, and also excludes information about variable consideration allocated entirely to a wholly unsatisfied performance obligation.
Contract balances: The timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable is recorded at the invoiced amount, net of an allowance for doubtful accounts. A receivable is recognized in the period we deliver goods or provide services or when our right to consideration is unconditional. A contract asset is recorded when we have performed under the contract but our right to consideration is conditional on something other than the passage of time. Contract assets as of September 25, 2021 and December 26, 2020 were $2.4 million and $3.7 million, respectively, and are reported on the Condensed Consolidated Balance Sheets as a component of Prepaid expenses and other current assets.
Contract liabilities include payments received in advance of performance under a contract and are satisfied as the associated revenue is recognized. Contract liabilities are reported on the Condensed Consolidated Balance Sheets at the end of each reporting period as a component of Deferred revenue and Other liabilities. Contract liabilities as of September 25, 2021 and December 26, 2020 were $24.3 million and $22.2 million, respectively. During the nine months ended September 25, 2021, we recognized $15.0 million of revenue, that was included in contract liabilities as of December 26, 2020.
Costs to obtain a contract: We generally expense sales commissions when incurred as a component of Selling, general and administrative expense, as the amortization period is typically less than one year.
Revenue by Category: Refer to Note 16, Operating Segments and Enterprise-Wide Information, for further details.

Overview
FormFactor, Inc., headquartered in Livermore, California, is a leading provider of test and measurement technologies. We provide a broad range of high-performance probe cards, analytical probes, probe stations, metrology systems, thermal systems and cryogenic systems to both semiconductor companies and scientific institutions. Our products provide electrical and physical information from a variety of semiconductor and electro-optical devices and integrated circuits from early research, through development, to high-volume production. Customers use our products and services to lower production costs, improve yields, and enable development of their complex next-generation products.
We operate in two reportable segments consisting of the Probe Cards segment and the Systems segment. Sales of our probe cards and analytical probes are included in the Probe Cards segment, while sales of our probe stations, metrology systems, and thermal and cryogenic systems are included in the Systems segment.
We generated net income of $58.0 million in the first nine months of fiscal 2021 as compared to $59.3 million in the first nine months of fiscal 2020. The small decrease in net income was primarily due to increased revenues, partially offset by slightly lower margins on a lower mix of Foundry & Logic probe card sales and higher taxes on higher taxable income and a higher tax rate due to significant one-time tax benefits during 2020.
Impact of COVID-19
The COVID-19 pandemic continues to cause serious illness and death in many of the regions that we, our customers and our suppliers operate. The COVID-19 pandemic has resulted in significant governmental actions designed to control the spread of the virus, including the imposition of safety requirements and other orders in locations where we have manufacturing and other activities.
We currently continue to operate in all of our manufacturing sites at production levels comparable to those prior to the pandemic, albeit subject to certain safety and related constraints. Our other operations are similarly continuing with substantial work-from-home activities.
If the provisions of governmental health orders or other safety requirements applicable to us or our customers or suppliers become more restrictive for an extended period of time, or if we have repeated occurrences of COVID-19 in any of our facilities, we may experience disruptions or delays in manufacturing, product design, product development, customer support, manufacturing and sales, and an overall loss of productivity and efficiency.
While to date the disruptions in our operations, supply chain and customer demand as a result of the COVID-19 pandemic have been somewhat limited, we believe that the COVID-19 pandemic represents a sustained threat that may give rise to a variety of more significant adverse impacts on our business and financial results. For a further description of the uncertainties and business risks associated with the COVID-19 pandemic, see the risk factors discussed in our Annual Report on Form 10-K for the year ended December 26, 2020.
Significant Accounting Policies and the Use of Estimates
Management’s Discussion and Analysis and Note 2, Summary of Significant Accounting Policies, to the Consolidated Financial Statements in our 2020 Annual Report on Form 10-K describe the significant accounting estimates and significant accounting policies used in preparation of the Consolidated Financial Statements. Actual results in these areas could differ from management’s estimates. During the nine months ended September 25, 2021, there were no significant changes in our significant accounting policies or estimates from those reported in our Annual Report on Form 10-K for the year ended December 26, 2020, which was filed with the Securities and Exchange Commission on February 22, 2021.

The decrease in Foundry & Logic product revenue for the three months ended September 25, 2021, compared to the three months ended September 26, 2020, was driven by lower demand from two major customers, partially offset by increased unit sales to other large semiconductor foundries and integrated device manufacturers. The decrease for the nine months ended September 25, 2021, compared to the nine months ended September 26, 2020, was driven by lower demand from one major customer, partially offset by increased unit sales to other large semiconductor foundries and integrated device manufacturers. The relative stability of our overall revenue, despite these fluctuations, is the result of our long-term customer and market diversification initiatives.
The increase in DRAM product revenue for the three and nine months ended September 25, 2021, compared to the three and nine months ended September 26, 2020, was driven by increased sales to several customers and strong market-based demand for DRAM products through the first three quarters of fiscal 2021.
Flash product revenue was down slightly for the three months ended September 25, 2021, compared to the three months ended September 26, 2020, with shifts between customers that are typical as our revenue in this market continues to be highly variable. The increase in Flash product revenue for the nine months ended September 25, 2021, compared to the nine months ended September 26, 2020, was driven by increased sales resulting from the acquisition of Baldwin Park offset by decreased sales as a result of decreased customer demand for our existing products.
The increase in Systems product revenue for the three and nine months ended September 25, 2021, compared to the three and nine months ended September 26, 2020, was driven by increased sales of cryogenic systems due to the acquisition of High Precision Devices, Inc. (“HPD”) and increased sales of thermal sub-systems and metrology systems.

For example, if a certain South Korean customer purchases through their U.S. subsidiary and requests the products to be shipped to an address in South Korea, this sale will be reflected in the revenue for South Korea rather than the U.S.
Changes in revenue by geographic region for the three and nine months ended September 25, 2021, compared to the three and nine months ended September 26, 2020, were primarily attributable to changes in customer demand, shifts in customer regional manufacturing strategies, particularly with our large multinational customers, and product sales mix.
Cost of Revenues and Gross Margins
Cost of revenues consists primarily of manufacturing materials, compensation and benefits, shipping and handling costs, manufacturing-related overhead and amortization of certain intangible assets. Our manufacturing operations rely on a limited number of suppliers to provide key components and materials for our products, some of which are a sole source. We order materials and supplies based on backlog and forecasted customer orders. Tooling and setup costs related to changing manufacturing lots at our suppliers are also included in the cost of revenues. We expense all warranty costs, inventory provisions and amortization of certain intangible assets as cost of revenues.

Probe Cards
For the three and nine months ended September 25, 2021, gross margins decreased compared to the three and nine months ended September 26, 2020, primarily due to higher material costs driven by fluctuations in commodity costs, somewhat offset by higher standard margins on Foundry & Logic sales.
Systems
For the three and nine months ended September 25, 2021, gross margins increased compared to the three and nine months ended September 26, 2020, primarily as a result of favorable product mix, largely related to increased sales of metrology systems and thermal sub-systems.
Corporate and Other
Corporate and Other includes unallocated expenses relating to share-based compensation and amortization of intangible assets, inventory and fixed asset fair value adjustments due to acquisitions, and restructuring which are not used in evaluating the results of, or in allocating resources to, our reportable segments.
Overall
Gross profit and gross margins fluctuate with revenue levels, product mix, selling prices, factory loading and material costs. For the three and nine months ended September 25, 2021, compared to the three and nine months ended September 26, 2020, gross profit has increased on greater revenue levels while gross margins have decreased, primarily on higher material costs, partially offset by a more favorable product mix.

The increase in research and development expenses in the three and nine months ended September 25, 2021 when compared to the corresponding period in the prior year was primarily driven by our recent acquisitions of Baldwin Park and HPD, which increased headcount and general operational costs. Annual salary increases, higher stock-based compensation, and restructuring charges also contributed to the increase.

The decrease in selling, general and administrative expenses in the three months ended September 25, 2021 when compared to the corresponding period in the prior year was primarily driven by decreased information technology security remediation costs that were incurred during the three months ended September 26, 2020 that did not repeat. This decrease was partially offset by higher stock-based compensation.
The increase in selling, general and administrative expenses in the nine months ended September 25, 2021 when compared to the corresponding period in the prior year was primarily driven by our recent acquisitions of Baldwin Park and HPD, which increased headcount and general operational costs.

These increases were partially offset by the benefit in the prior year related to adjustments to contingent consideration for the acquisition of FRT GmbH ("FRT") and information technology security remediation costs that both did not repeat.

Weighted average interest rate on debt | 1.59 | % |  | 1.65 | % |  | 1.58 | % |  | 2.05 | %

Interest income is earned on our cash, cash equivalents, restricted cash and marketable securities. The decrease in interest income for the three and nine months ended September 25, 2021 compared with the corresponding period of the prior year was attributable to lower investment yields due to the low interest rate environment, despite higher invested balances.
Interest expense primarily includes interest on our term loans, interest rate swap derivative contracts, and term loan issuance costs amortization charges. The decrease in interest expense for the three and nine months ended September 25, 2021 compared to the same period of the prior year was primarily due to lower outstanding debt balances due to the June 30, 2020 pay-off of the term loan originated to acquire Cascade Microtech, Inc, partially offset by the Building Term Loan originated in the second quarter of 2020. Interest expense was also lower due to lower average interest rates on the outstanding debt.
Other Income (Expense), Net
Other income (expense), net, primarily includes the effects of foreign currency impact and various other gains and losses.
Provision for Income Taxes

| Three Months Ended |  | Nine Months Ended
| September 25, 2021 |  | September 26, 2020 |  | September 25, 2021 |  | September 26, 2020
| (In thousands, except percentages)
Provision (benefit) for income taxes | $ | 2,784 |  |  | $ | (499) |  |  | $ | 8,273 |  |  | $ | 4,479 |
Effective tax rate | 12.0 | % |  | (2.2) | % |  | 12.5 | % |  | 7.0 | %

Provision for income taxes reflects the tax provision on our operations in foreign and U.S. jurisdictions, offset by tax benefits from tax credits and the foreign-derived intangible income (“FDII”) deduction. Our effective tax rate may vary from period to period based on changes in estimated taxable income or loss by jurisdiction, changes to the valuation allowance, changes to U.S. federal, state or foreign tax laws, changes in ASC 718 stock-based compensation expense/benefit, future expansion into areas with varying country, state, and local income tax rates, and deductibility of certain costs and expenses by jurisdiction. We have utilized our previous net operating loss carryforwards, and expect the FDII deduction and corresponding benefit to be available, resulting in a decrease from the U.S. statutory rate and included in our worldwide effective tax rate for the year ending December 25, 2021.
The increase in the effective tax rate in the nine months ended September 25, 2021 when compared to the corresponding period in the prior year was primarily driven by the cumulative effect of adjustments made related to final and proposed Treasury regulations during the third quarter ended September 26, 2020. The regulations under Sections 951A and 954 provided final global intangible low-taxed income (GILTI) high-tax exclusion and proposed changes to the existing subpart F income high-tax exception, respectively. The impact of those adjustments provided a significant one time tax benefit during 2020.
Liquidity and Capital Resources
Capital Resources
Our working capital was $346.5 million at September 25, 2021, compared to $332.5 million at December 26, 2020.
Cash and cash equivalents primarily consist of deposits held at banks, money market funds, and U.S. treasuries. Marketable securities primarily consist of U.S. treasuries, corporate bonds, and commercial paper. We typically invest in highly-rated
32

securities with low probabilities of default. Our investment policy requires investments to be rated single A or better, and limits the types of acceptable investments, issuer concentration and duration of the investment.
Our cash, cash equivalents and marketable securities totaled approximately $264.7 million at September 25, 2021, compared to $255.0 million at December 26, 2020. We believe that we will be able to satisfy our working capital requirements and scheduled term loan repayments for at least the next twelve months with the liquidity provided by our existing cash, cash equivalents, marketable securities and cash provided by operations. To the extent necessary, we may consider entering into short and long-term debt obligations, raising cash through a stock issuance, or obtaining new financing facilities, which may not be available on terms favorable to us. Our future capital requirements may vary materially from those now planned.
The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains and created significant volatility and disruption of financial markets. An extended period of global supply chain and economic disruption could materially affect our business, results of operations, access to sources of liquidity and financial condition.
If we are unsuccessful in maintaining or growing our revenues, maintaining or reducing our cost structure (in response to a potential reduction in demand due to an industry downturn, COVID-19, or other event), or increasing our available cash through debt or equity financings, our cash, cash equivalents and marketable securities may decline.
We utilize a variety of tax planning and financing strategies to manage our worldwide cash and deploy funds to locations where needed. As part of these strategies, we indefinitely reinvest a portion of our foreign earnings. Should we require additional capital in the United States, we may elect to repatriate indefinitely-reinvested foreign funds or raise capital in the United States.
Cash Flows
The following table sets forth our net cash flows from operating, investing and financing activities:

| Nine Months Ended
| September 25, 2021 |  | September 26, 2020
| (In thousands)
Net cash provided by operating activities | $ | 100,437 |  |  | $ | 124,209 |
Net cash used in investing activities | $ | (94,976) |  |  | $ | (56,195) |
Net cash used in financing activities | $ | (36,869) |  |  | $ | (28,970) |

Operating Activities
Net cash provided by operating activities for the nine months ended September 25, 2021 was primarily attributable to net income of $58.0 million and net non-cash expenses of $77.4 million, further impacted by changes in operating assets and liabilities, as explained below.
Inventories, net, increased $15.9 million to $115.1 million at September 25, 2021, compared to $99.2 million at December 26, 2020, as a result of anticipated projected customer demand. Due to provisions for excess and obsolete inventories of $11.6 million and non-cash restructuring charges to record inventory impairments of $1.3 million, the change in Inventories, net, was further impacted.
Operating lease liabilities increased $5.7 million to $40.4 million at September 25, 2021, compared to $34.7 million at December 26, 2020 as a result of additional right-of-use assets obtained in exchange for lease obligations of $11.7 million offset by lease payments.
Investing Activities
Net cash used in investing activities for the nine months ended September 25, 2021 was primarily related to $51.4 million property, plant and equipment acquisitions, and $43.6 million net cash used to purchase marketable securities.
Financing Activities
Net cash used in financing activities for the nine months ended September 25, 2021 primarily related to $24.0 million used to purchase common stock under our stock repurchase program, $12.6 million related to tax withholding associated with the net share settlements of our equity awards, $7.0 million of principal payments made towards the repayment of our term loans, and $3.9 million paid to settle the contingent consideration from the acquisition of FRT, partially offset by $10.6 million of proceeds received from issuances of common stock under our employee stock purchase plan and stock option plans.

Debt
FRT Term Loan
On October 25, 2019, we entered into a $23.4 million three-year credit facility loan agreement (the “FRT Term Loan”), to fund the acquisition of FRT GmbH, which we acquired on October 9, 2019.
The FRT Term Loan bears interest at a rate equal to the Euro Interbank Offered Rate (“EURIBOR”) plus 1.75% per annum and will be repaid in quarterly installments of approximately $2.0 million plus interest. The interest rate at September 25, 2021 was 1.20%. As of September 25, 2021, the balance outstanding pursuant to the FRT term loan was $10.3 million.
Building Term Loan
On June 22, 2020, we entered into an $18.0 million 15-year credit facility loan agreement (the “Building Term Loan”). The proceeds of the Building Term Loan were used to finance the purchase a building adjacent to our leased facilities in Livermore, California.
The Building Term Loan bears interest at a rate equal to the applicable LIBOR rate plus 1.75% per annum. Interest payments are payable in monthly installments over a fifteen-year period. The interest rate at September 25, 2021 was 1.84%. As of September 25, 2021, the balance outstanding pursuant to the Building Term Loan was $16.8 million.
On March 17, 2020, we entered into a forward starting interest rate swap agreement to hedge the interest payments on the Building Term Loan for the notional amount of $18.0 million, and an amortization period that matches the debt. As future levels of LIBOR over the life of the loan are uncertain, we entered into this interest-rate swap agreement to hedge the exposure in interest rate risks associated with movement in LIBOR rates. By entering into the agreement, we converted a floating rate interest at one-month LIBOR plus 1.75% into a fixed rate interest at 2.75%. As of September 25, 2021, the notional amount of the loan that is subject to this interest rate swap is $16.8 million.
Stock Repurchase Program
In October 2020, our Board of Directors authorized a program to repurchase up to $50.0 million of outstanding common stock to offset potential dilution from issuances of common stock under our stock-based compensation plans. The share repurchase program will expire on October 28, 2022. During the nine months ended September 25, 2021, we repurchased 620,200 shares of common stock for $24.0 million and, as of September 25, 2021, $26.0 million remained available for future repurchases.
Contractual Obligations and Commitments
The following table summarizes our significant contractual commitments to make future payments in cash under contractual obligations as of September 25, 2021:

(1) Represents our minimum interest payment commitments at 1.84% per annum for the Building Term Loan and 1.20% per annum for the FRT Term Loan. This also excludes any amounts related to our interest rate swap.
Off-Balance Sheet Arrangements
Historically, we have not participated in transactions that have generated relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As of September 25, 2021, we were not involved in any such off-balance sheet arrangements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk
For financial market risks related to changes in interest rates and foreign currency exchange rates, reference is made to Item 7A “Quantitative and Qualitative Disclosures about Market Risk” contained in Part II of our Annual Report on Form 10-K for the fiscal year ended December 26, 2020. Our exposure to market risk has not changed materially since December 26, 2020.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Based on our management’s evaluation (with the participation of our principal executive officer and principal financial officer), as of the end of the period covered by this report, our principal executive officer and principal financial officer have concluded that our 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”)) are effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Limitations on the Effectiveness of Controls
Control systems, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control systems’ objectives are being met. Further, the design of any control systems must reflect the fact that there are resource constraints, and the benefits of all controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of a simple error or mistake. Control systems can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based, in part, on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.
CEO and CFO Certifications
We have attached as exhibits to this Quarterly Report on Form 10-Q the certifications of our Chief Executive Officer and Chief Financial Officer, which are required in accordance with the Exchange Act. We recommend that this Item 4 be read in conjunction with the certifications for a more complete understanding of the subject matter presented.
PART II - OTHER INFORMATION
Item 1A. Risk Factors
There have been no material changes during the nine months ended September 25, 2021 to the risk factors discussed in our Annual Report on Form 10-K for the year ended December 26, 2020. If any of the identified risks actually occur, our business, financial condition and results of operations could suffer. The trading price of our common stock could decline and you may lose all or part of your investment in our common stock. The risks and uncertainties described in our Annual Report on Form 10-K for the year ended December 26, 2020 are not the only ones we face. Additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business operations.
