Accounting Policies [Abstract]  
BASIS OF PRESENTATION BASIS OF PRESENTATION
Integer Holdings Corporation (together with its consolidated subsidiaries, “Integer” or the “Company”) is a publicly-traded corporation listed on the New York Stock Exchange under the symbol “ITGR.” Integer is one of the largest medical device outsource manufacturers in the world serving the cardiac, neuromodulation, vascular, orthopedics, advanced surgical and portable medical markets. The Company provides innovative, high-quality medical technologies that enhance the lives of patients worldwide. In addition, it develops batteries for high-end niche applications in the energy, military, and environmental markets. The Company’s reportable segments are: (1) Medical and (2) Non-Medical. The Company’s customers include large multi-national original equipment manufacturers (“OEMs”) and their affiliated subsidiaries.
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information (Accounting Standards Codification (“ASC”) 270, Interim Reporting) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all of the information necessary for a full presentation of financial position, results of operations, and cash flows in conformity with GAAP. In the opinion of management, the condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the results of the Company for the periods presented. Intercompany transactions and balances have been fully eliminated in consolidation.
Operating results for interim periods are not necessarily indicative of results that may be expected for the fiscal year as a whole. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, certain components of equity, sales, expenses, and related disclosures at the date of the financial statements and during the reporting period. Actual results could differ materially from these estimates. For further information, refer to the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.
The third quarter and first nine months of 2021 ended on October 1 and consisted of 91 days and 274 days, respectively. The third quarter and first nine months of 2020 ended on October 2 and consisted of 91 days and 276 days, respectively.
Risks and Uncertainties
Beginning in early March 2020, the global spread of the novel coronavirus (“COVID-19”) created significant uncertainty and worldwide economic disruption. Specific impacts to the Company’s business include labor shortages, disruptions in the supply chain, delayed or reduced customer orders and sales, restrictions on associates’ ability to travel or work, and delays in shipments to and from certain countries. The extent to which COVID-19 will continue to impact the Company’s operations depends on future developments, which remain highly uncertain and difficult to predict, including, among others, the duration of the outbreak, the effectiveness and utilization of vaccines for COVID-19 and its variants, new information that may emerge concerning the severity of COVID-19 and the actions, especially those taken by governmental authorities to contain the pandemic or treat its impact. As pandemic-related events continue to evolve, additional impacts may arise that the Company is not aware of currently. Any prolonged material disruption of the Company’s labor force, suppliers, manufacturing, or customers could materially impact its consolidated financial position, results of operations or cash flows.
Recent Accounting Pronouncements
The Company considers the applicability and impact of all Accounting Standard Updates (“ASU”) issued by the Financial Accounting Standards Board (“FASB”). The Company evaluated all recent accounting pronouncements issued, including those that are currently effective, and determined that the adoption of these pronouncements would not have a material effect on the financial position, results of operations or cash flows of the Company. There have been no new or material changes to the significant accounting policies discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, that are of significance, or potential significance, to the Company.

Business Combination and Asset Acquisition [Abstract]  
BUSINESS ACQUISITION BUSINESS ACQUISITION
On February 19, 2020, the Company acquired certain assets and liabilities of InoMec Ltd. (“InoMec”), a privately-held company based in Israel that specializes in the research, development and manufacturing of medical devices, including minimally invasive tools, delivery systems, tubing and catheters, surgery tools, drug-device combination, laser combined devices, and tooling and production. The acquisition enables the Company to create a research and development center in Israel, closer to the customer base in the region. The fair value of the consideration transferred was $7.0 million, which included an initial cash payment of $5.3 million and $1.7 million in estimated fair value of contingent consideration.
The contingent consideration represents the estimated fair value of the Company’s obligation, under the asset purchase agreement, to make additional payments of up to $3.5 million over the four years following the acquisition based on specified conditions being met. Based on the final purchase price allocation, the assets acquired principally comprise $2.0 million of intangible assets, $4.8 million of goodwill, $0.3 million of acquired property, plant and equipment, and a net liability for other working capital items of $0.1 million. Intangible assets included developed technology, customer relationships and non-compete provisions, which are being amortized over a weighted average period of 5.9 years from the date of acquisition.
The amount allocated to goodwill for this acquisition is deductible for income tax purposes. The fair value of the contingent consideration was estimated using the Monte Carlo valuation approach. See Note 13 “Financial Instruments and Fair Value Measurements” for additional information related to the fair value measurement of the contingent consideration.
For segment reporting purposes, the results of operations and assets from this acquisition have been included in the Company’s Medical segment since the acquisition date. Sales and earnings related to the operations consisting of the assets and liabilities acquired from InoMec for the three and nine months ended October 1, 2021 and October 2, 2020 were not material. There were no direct costs incurred for this acquisition during 2021. During the three and nine months ended October 2, 2020, direct costs of this acquisition of $0.1 million and $0.9 million, respectively, were expensed as incurred and included in Other operating expenses in the Condensed Consolidated Statements of Operations and Comprehensive Income.
Pro forma financial information has not been presented for this acquisition as the net effects were not significant or material to the Company’s results of operations or financial position.

Total long-term debt$610,405 $693,758 
On September 2, 2021, the Company entered into a new credit agreement (the “2021 Credit Agreement”) which permits borrowings and other extensions of credit in an initial aggregate principal amount of up to $1 billion (as may be increased from time to time in accordance with the terms). The 2021 Credit Agreement governs the Company’s senior secured credit facilities (the “Senior Secured Credit Facilities”), which consist of a five-year $400 million revolving credit facility (the “Revolving Credit Facility”), a five-year “term A” loan (the “TLA Facility”) and a seven-year “term B” loan (the “TLB Facility” and, together with the TLA Facility, the “Term Loan Facilities”). The TLB Facility was issued at a 0.50% discount. The 2021 Credit Agreement also includes an alternative benchmark rate as a replacement to the London Interbank Offered Rate (“LIBOR”) in the event LIBOR is no longer available.
The obligations under the 2021 Credit Agreement are guaranteed by certain specified subsidiaries of the Company. Among other things, the 2021 Credit Agreement contains covenants that restrict the Company’s and certain of its subsidiaries’ ability to incur liens on certain assets, incur indebtedness, make material changes in corporate structure or materially alter the nature of its business, dispose of material assets, engage in mergers, consolidations and certain other fundamental changes, or engage in certain transactions with affiliates. The 2021 Credit Agreement contains customary default provisions, including, but not limited to, failure to pay interest or principal when due and failure to comply with covenants.
Prior to September 2, 2021, the Company was party to an amended and restated credit agreement (the “2015 Credit Agreement”), dated as of October 27, 2015. The 2015 Credit Agreement provided for certain credit facilities to the Company in an aggregate principal amount not to initially exceed $1.6 billion. The 2015 Credit Agreement was terminated concurrently with entering into the 2021 Credit Agreement.
Revolving Credit Facility
The Revolving Credit Facility matures on September 2, 2026 and includes $40 million sublimits for swingline loans and for standby letters of credit. As of October 1, 2021, the Company had available borrowing capacity on the Revolving Credit Facility of $357.0 million after giving effect to $37.3 million of outstanding borrowings and $5.7 million of outstanding standby letters of credit.
Interest rates on the Revolving Credit Facility, as well as the TLA Facility, are at the Company’s option, either at: (i) the applicable LIBOR (or an applicable benchmark replacement) plus the applicable margin, which will range between 1.25% and 2.25%, based on the Company’s Total Net Leverage Ratio, or (ii) the Base Rate (as defined below) plus the applicable margin, which will range between 0.25% and 1.25%, based on the Company’s Total Net Leverage Ratio. The Base Rate is defined, for any day, as the per annum rate equal to the highest of (i) the prime rate (as defined in the 2021 Credit Agreement), (ii) the Federal Funds Rate, as published by the Federal Reserve Bank of New York, plus 0.50%, and (iii) one-month LIBOR plus 1.00%. As of October 1, 2021, the weighted average interest rate on outstanding borrowings under the Revolving Credit Facility was 1.83%.
The Company is required to pay a commitment fee on the unused portion of the Revolving Credit Facility, which will range between 0.15% and 0.25%, depending on the Company’s Total Net Leverage Ratio (as defined in the 2021 Credit Agreement). As of October 1, 2021, the commitment fee on the unused portion of the Revolving Credit Facility was 0.20%.

Term Loan Facilities
The TLA Facility and TLB Facility mature on September 2, 2026 and September 2, 2028, respectively, and require quarterly installments which increase over the term of the loans. Interest rates on the TLB Facility are, at the Company’s option, either at: (i) the applicable LIBOR rate plus 2.50%, with LIBOR subject to a 0.50% floor, or (ii) the Base Rate plus 1.50%. As of October 1, 2021, the interest rates on the TLA Facility and TLB Facility were 1.83% and 3.00%, respectively.
Covenants
The 2021 Credit Agreement contains customary terms and conditions, including representations and warranties and affirmative and negative covenants, as well as financial covenants for the benefit of the lenders under the Revolving Credit Facility and the TLA Facility, which require that (i) the Company maintain a Total Net Leverage Ratio not to exceed 5.50:1.00 (stepping down to 5.00:1.00 for the third fiscal quarter of 2023 through maturity and subject to increase in certain circumstances following qualified acquisitions, but at no time shall exceed 5.50:1.00) and (ii) the Company maintain an interest coverage ratio of at least 2.50:1.00. The TLB Facility does not contain any financial maintenance covenants. As of October 1, 2021, the Company was in compliance with these financial covenants.
Contractual maturities under the Senior Secured Credit Facilities for the remainder of 2021 and through maturity, excluding any discounts or premiums, as of October 1, 2021 are as follows (in thousands):

Debt Issuance Costs and Discounts
In connection with terminating the 2015 Credit Agreement and entering into the 2021 Credit Agreement, for each separate debt instrument on a lender by lender basis, in accordance with ASC 470-50, Debt Modifications and Extinguishment, the Company performed an assessment of whether the transaction was deemed to be new debt, a modification of existing debt, or an extinguishment of existing debt. Debt issuance costs are either deferred and amortized over the term of the associated debt or expensed as incurred.
Based on this assessment, $1.2 million of unamortized debt issuance costs and discount related to the 2015 Credit Agreement were deemed to be related to the issuance of new debt, or the modification of existing debt, and therefore will continue to be deferred and amortized over the term of the associated debt. The remaining $3.3 million of unamortized debt issuance costs and discount related to the 2015 Credit Agreement were deemed to be related to the extinguishment of debt and were expensed and included in Interest Expense in the accompanying Consolidated Statements of Operations and Comprehensive Income.
Additionally, during the nine month period ended October 1, 2021, in connection with prepayments on TLB Facility under the 2015 Credit Agreement, $0.5 million of unamortized debt issuance costs and discount were treated as extinguishment of debt and were expensed and included in Interest Expense in the accompanying Consolidated Statements of Operations and Comprehensive Income.
In connection with the 2021 Credit Agreement, the Company incurred and capitalized $8.8 million of issuance costs, including an original issue discount on the TLB Facility of $1.8 million. An aggregate of $6.0 million of original issue discount and debt issuance costs have been recorded as a reduction of the carrying value of the related debt and $2.8 million of debt issuance costs attributable to the Revolving Credit Facility have been recorded as a component of Other assets on the Condensed Consolidated Balance Sheets as of October 1, 2021.

Share-based Payment Arrangement [Abstract]  
STOCK-BASED COMPENSATION STOCK-BASED COMPENSATION
The Company maintains certain stock-based compensation plans that were approved by the Company’s stockholders and are administered by the Board of Directors (the “Board”) or the Compensation and Organization Committee of the Board. The stock-based compensation plans provide for the granting of stock options, restricted stock awards, restricted stock units (“RSUs”), stock appreciation rights and stock bonuses to employees, non-employee directors, consultants, and service providers.
On March 25, 2021, the Company’s Board adopted, subject to stockholder approval, the Integer Holdings Corporation 2021 Omnibus Incentive Plan (the “2021 Plan”). The Company’s stockholders approved the 2021 Plan at the Company’s 2021 annual meeting of stockholders on May 19, 2021, at which time the 2021 Plan replaced the Company’s 2016 Stock Incentive Plan (the “2016 Plan”) and the Company ceased granting any new awards under the 2016 Plan. The number of shares initially reserved for issuance under the 2021 Plan is (i) 1,450,000 plus (ii) the total number of shares of common stock available for issuance under the 2016 Plan, plus (iii) any shares of common stock that are subject to awards forfeited, cancelled, expired, terminated or otherwise lapsed or settled in cash, in whole or in part, without the delivery of shares under the 2016 Plan. Each of the Company’s 2011 Stock Incentive Plan, the 2009 Stock Incentive Plan and the 2005 Stock Incentive Plan have expired, and no awards are available for issuance under these expired plans.

Restricted Stock Units
During the nine months ended October 1, 2021, the Company awarded grants of either time-based RSUs or a mix of time-based RSUs and performance-based RSUs (“PRSUs”) to certain members of its Board and management. New Board members appointed during the first quarter of 2021 received a pro-rated portion of the their annual equity retainer in the form of time-based RSUs that vest in accordance with the regularly scheduled vesting schedule applicable to existing members of the Board. All other time-based RSUs granted during the nine months ended October 1, 2021 vest over a period of three years from the grant date, subject to the recipient’s continuous service to the Company. For the Company’s PRSUs, in addition to service conditions, the ultimate number of shares to be earned depends on the achievement of market-based conditions. The market-based conditions are based on the Company’s achievement of a relative total shareholder return (“TSR”) performance requirement, on a percentile basis, compared to a defined group of peer companies over three year performance periods.
The Company uses a Monte Carlo simulation model to determine the grant-date fair value of awards with TSR-based performance conditions. The grant-date fair value of all other RSUs is equal to the closing market price of Integer common stock on the date of grant.
The weighted average fair value and assumptions used to value the TSR portion of the PRSUs granted are as follows:

The valuation of the TSR portion of the PRSUs granted during 2021 and 2020 also reflects a weighted average illiquidity discount of 8.19% and 8.00%, respectively, related to the six-month period that recipients are restricted from selling, transferring, pledging or assigning the underlying shares, in the event of vesting.

Operational excellence initiatives
The Company’s operational excellence (“OE”) initiatives mainly consist of costs associated with executing on its sales force, manufacturing, business process and performance excellence operational strategic imperatives. These projects focus on changing the Company’s organizational structure to match product line growth strategies and customer needs, transitioning its manufacturing process into a competitive advantage and standardizing and optimizing its business processes.
2021 OE Initiatives - Costs related to the Company’s 2021 OE initiatives are primarily recorded within the Medical segment or unallocated operating expenses and mainly include termination benefits. The Company estimates that it will incur aggregate pre-tax charges in connection with the 2021 OE initiatives of between approximately $3 million to $4 million, the majority of which are expected to be cash expenditures. As of October 1, 2021, total restructuring and related charges incurred since inception was $2.3 million. These actions are expected to be substantially complete by the end of 2021.
2020 OE Initiatives - Costs related to the Company’s 2020 OE initiatives are primarily recorded within the Medical segment and mainly include termination benefits. As of October 1, 2021, total restructuring and related charges incurred since inception was $3.1 million. These actions were substantially complete at the end of 2020.
Strategic reorganization and alignment
These initiatives primarily included aligning resources with the Company’s strategic direction, improving profitability to invest in accelerated growth and the expansion of a facility. These actions began in 2017 and were completed during the second quarter of 2020. The Company recorded, primarily within the Medical segment, $23.0 million of restructuring and related charges since inception.
Manufacturing alignment to support growth
These initiatives were designed to reduce costs, increase manufacturing capacity to accommodate growth and improve operating efficiencies by relocating certain manufacturing operations and expanding certain facilities. These actions began in 2017 and were completed during the fourth quarter of 2020. The Company recorded, primarily within the Medical segment, $5.8 million of restructuring and related charges since inception.

Income Taxes

Income Tax Disclosure [Abstract]  
INCOME TAXES INCOME TAXES
The income tax provision for interim periods is determined using an estimate of the annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the estimate of the annual effective tax rate is updated, and if the estimated effective tax rate changes, a cumulative adjustment is made. There is a potential for volatility of the effective tax rate due to several factors, including discrete items, changes in the mix and amount of pre-tax income and the jurisdictions to which it relates, changes in tax laws and foreign tax holidays, business reorganizations, settlements with taxing authorities and foreign currency fluctuations. In addition, the Company continues to explore tax planning opportunities that may have a material impact on its effective tax rate.
The Company’s effective tax rate for the third quarter of 2021 was 4.8% on $23.2 million of income before taxes compared to 3.4% on $31.4 million of income before taxes for the same period in 2020. The Company’s effective tax rate for the first nine months of 2021 was 7.5% on $78.9 million of income before taxes compared to 9.3% on $68.2 million of income before taxes for the same period in 2020. The difference between the Company’s effective tax rates and the U.S. federal statutory income tax rate of 21% for the third quarter and first nine months of 2021 and 2020 is due principally to the net impact of the Company’s earnings outside the U.S., which are generally taxed at rates that differ from the U.S federal rate, the Global Intangible Low-Taxed Income (“GILTI”) tax, the availability of tax credits, and the recognition of certain discrete tax benefits. The Company recorded discrete tax benefits of $1.6 million and $6.1 million, respectively, for the third quarter and first nine months of 2021, compared to discrete tax benefits of $4.9 million and $5.9 million, respectively, for the third quarter and first nine months of 2020. Approximately $3.5 million of the discrete tax benefits recognized for the first nine months of 2021 relate to the reversal of unrecognized tax benefits resulting from the effective settlement of tax audits during the second quarter of 2021. The remainder of the discrete tax benefits relate predominately to excess tax benefits recognized upon vesting of RSUs or exercise of stock options during those quarters and favorable return to provision adjustments related to the 2020 tax year.
Unrecognized tax benefits reflect the difference between positions taken or expected to be taken on income tax returns and the amounts reflected in the financial statements. As of October 1, 2021, the Company had unrecognized tax benefits of approximately $4.4 million, of which approximately $4.4 million would favorably impact the effective tax rate, net of federal benefit on state issues, if recognized. As of October 1, 2021, the Company believes the reasonably possible total amount of unrecognized tax benefits that could increase or decrease in the next 12 months as a result of various statute expirations, audit closures, and/or tax settlements would not be material to its consolidated financial statements.
In response to the COVID-19 pandemic, many governments have enacted or are contemplating measures to provide aid and economic stimulus. These measures may include deferring the due dates of tax payments or other changes to their income and non-income-based tax laws. The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), which was enacted on March 27, 2020 in the U.S., includes measures to assist companies, including temporary changes to income and non-income- based tax laws. The CARES Act provides for deferred payment of the employer portion of social security taxes through the end of 2020, with 50% of the deferred amount due January 3, 2022 and the remaining 50% due January 3, 2023. As of October 1, 2021 and December 31, 2020, the Company had deferred a total of $9.7 million of payroll taxes. The deferred payroll taxes are included within Accrued expenses and other current liabilities and Other long-term liabilities on the Condensed Consolidated Balance Sheets.

Contingent Consideration Arrangements
The Company records contingent consideration liabilities related to the earn-out provisions for certain acquisitions. See Note 13 “Financial Instruments and Fair Value Measurements” for additional information.
Litigation
The Company is subject to litigation arising from time to time in the ordinary course of its business. The Company does not expect that the ultimate resolution of any pending legal actions will have a material effect on its consolidated results of operations, financial position, or cash flows. However, litigation is subject to inherent uncertainties. As such, there can be no assurance that any pending legal action, which the Company currently believes to be immaterial, will not become material in the future.
In April 2013, the Company commenced an action against AVX Corporation and AVX Filters Corporation (collectively “AVX”) alleging that AVX had infringed on the Company’s patents by manufacturing and selling filtered feedthrough assemblies used in implantable pacemakers and cardioverter defibrillators that incorporate the Company’s patented technology. Following four trials and an appeal, the United States Court of Appeals for the Federal Circuit affirmed, in all respects, a judgment in favor of the Company. The Company received the payment of $28.9 million in October 2020, and after recognizing certain related expenses, recognized a net gain of $28.2 million.
Selling, general and administrative expenses
The net gain on patent litigation of $28.2 million is recorded in Selling, general and administrative expenses in the Company’s Condensed Consolidated Statements of Operations and Comprehensive Income for the three and nine months ended October 2, 2020.

Assets and Liabilities Measured at Fair Value on a Recurring Basis
Fair value measurement standards apply to certain financial assets and liabilities that are measured at fair value on a recurring basis (each reporting period). For the Company, these financial assets and liabilities include its derivative instruments and contingent consideration. The Company does not have any nonfinancial assets or liabilities that are measured at fair value on a recurring basis.
The Company is exposed to global market risks, including the effect of changes in interest rates and foreign currency exchange rates, and uses derivatives to manage these exposures that occur in the normal course of business. The Company does not hold or issue derivatives for trading or speculative purposes. All derivatives are recorded at fair value on the Condensed Consolidated Balance Sheets.

Interest Rate Swaps
The Company periodically enters into interest rate swap agreements in order to reduce the cash flow risk caused by interest rate changes on its outstanding floating rate borrowings. Under these swap agreements, the Company pays a fixed rate of interest and receives a floating rate equal to one-month LIBOR. The variable rate received from the swap agreements and the variable rate paid on the outstanding debt will have the same rate of interest, excluding the credit spread, and will reset and pay interest on the same date. The Company has designated these swap agreements as cash flow hedges based on concluding the hedged forecasted transaction is probable of occurring within the period the cash flow hedge is anticipated to affect earnings.

(1)Amounts for 2021 periods consist of payments associated with the Company’s acquisitions of InoMec and USB, resulting from achievement of revenue-based goals for the period from March 1, 2020 to February 28, 2021 for InoMec and January 1, 2020 to December 31, 2020 for USB. Amounts for 2020 periods consist of a payment made to settle a portion of a contingent consideration arrangement relating to a license to use technology.
On February 19, 2020, the Company acquired certain assets and liabilities of InoMec. See Note 2 “Business Acquisition” for additional information about the InoMec acquisition. On October 7, 2019, the Company acquired certain assets and liabilities of USB, a privately-held developer and manufacturer of complex braided biomedical structures for disposable and implantable medical devices. The contingent consideration at October 1, 2021 is the estimated fair value of the Company’s obligations, under the asset purchase agreements for InoMec and USB, to make additional payments if certain revenue goals are met.
(13.)     FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS (Continued)
As of October 1, 2021, the current portion of contingent consideration liabilities is $1.0 million and included in Accrued expenses and other current liabilities, and the non-current portion is $1.3 million and included in Other long-term liabilities on the Condensed Consolidated Balance Sheets. As of December 31, 2020, the current portion of contingent consideration liabilities was $1.7 million and included in Accrued expenses and other current liabilities, and the non-current portion was $2.2 million and included in Other long-term liabilities on the Condensed Consolidated Balance Sheets.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
Fair value standards also apply to certain assets and liabilities that are measured at fair value on a nonrecurring basis. The carrying amounts of cash, accounts receivable, accounts payable, and accrued expenses approximate fair value because of the short-term nature of these items.
Borrowings under the Company’s Revolving Credit Facility, TLA Facility and TLB Facility accrue interest at a floating rate tied to a standard short-term borrowing index, selected at the Company’s option, plus an applicable margin. The carrying amount of this floating rate debt approximates fair value based upon the respective interest rates adjusting with market rate adjustments.
Equity Investments
The Company holds long-term, strategic investments in companies to promote business and strategic objectives. These investments are included in Other long-term assets on the Condensed Consolidated Balance Sheets. Non-marketable equity securities are equity securities without readily determinable fair value. The Company has elected the practicability exception to use an alternative approach that measures the securities at cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes. If an impairment is recognized on the Company’s non-marketable equity securities during the period, these assets are classified as Level 3 within the fair value hierarchy based on the nature of the fair value inputs.

Accounting Policies [Abstract]  
Interim Basis of Accounting The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information (Accounting Standards Codification (“ASC”) 270, Interim Reporting) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all of the information necessary for a full presentation of financial position, results of operations, and cash flows in conformity with GAAP. In the opinion of management, the condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the results of the Company for the periods presented. Intercompany transactions and balances have been fully eliminated in consolidation.Operating results for interim periods are not necessarily indicative of results that may be expected for the fiscal year as a whole. For further information, refer to the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.The third quarter and first nine months of 2021 ended on October 1 and consisted of 91 days and 274 days, respectively. The third quarter and first nine months of 2020 ended on October 2 and consisted of 91 days and 276 days, respectively.
Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, certain components of equity, sales, expenses, and related disclosures at the date of the financial statements and during the reporting period. Actual results could differ materially from these estimates.
Recent Accounting Pronouncements
Recent Accounting Pronouncements
The Company considers the applicability and impact of all Accounting Standard Updates (“ASU”) issued by the Financial Accounting Standards Board (“FASB”). The Company evaluated all recent accounting pronouncements issued, including those that are currently effective, and determined that the adoption of these pronouncements would not have a material effect on the financial position, results of operations or cash flows of the Company. There have been no new or material changes to the significant accounting policies discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, that are of significance, or potential significance, to the Company.
Income Taxes The income tax provision for interim periods is determined using an estimate of the annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the estimate of the annual effective tax rate is updated, and if the estimated effective tax rate changes, a cumulative adjustment is made. There is a potential for volatility of the effective tax rate due to several factors, including discrete items, changes in the mix and amount of pre-tax income and the jurisdictions to which it relates, changes in tax laws and foreign tax holidays, business reorganizations, settlements with taxing authorities and foreign currency fluctuations. In addition, the Company continues to explore tax planning opportunities that may have a material impact on its effective tax rate.
