Financial Statement Presentation - The accompanying unaudited interim Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP” or “U.S. GAAP”) for complete financial statements. These unaudited interim Consolidated Financial Statements should therefore be read in conjunction with the Consolidated Financial Statements and Notes thereto for the year ended December 31, 20202021 included in the Company’s Annual Report on Form 10-K.

The accompanying unaudited interim Consolidated Financial Statements have been prepared in accordance with U.S. GAAP, which requires management to make estimates and assumptions that affect amounts reported in the Consolidated Financial Statements and accompanying disclosures. Although these estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may differ from those estimates. Management uses historical experience and all available information to make these estimates, including considerations for the impact of the COVID-19 pandemic on the macroeconomic environment. The situation related to the COVID-19 pandemic continues to be complex and rapidly evolving.dynamic. The Company cannot reasonably estimate the duration of the COVID-19 pandemic or fully ascertain its impact on the Company’s future results and market capitalization, which could adversely impact estimates such as the recoverability of goodwill and long-lived assets and the realizability of deferred tax assets. The unaudited interim Consolidated Financial Statements reflect all adjustments of a normal, recurring nature that are, in the opinion of management, necessary for a fair statement of results for these interim periods.

On April 28, 2022, the Company announced that its Board of Directors had increased the authorization by up to $150 million in additional aggregate value. The timing and amount of any shares repurchased will be determined by the Company based on its evaluation of market conditions and other factors, and will be made in accordance with applicable securities laws in either the open market or in privately negotiated transactions. The Company is not obligated to purchase any shares under the program, and the program may be suspended or discontinued at any time. The actual timing, number, and share price of shares repurchased will depend on a number of factors, including the market price of the Company’s common stock, general market and economic conditions, and applicable legal requirements. Any shares repurchased will be held as treasury stock. During the three months ended March 31, 2022, the Company repurchased 313,395 shares of common stock for a total of $6.8 million.

2. Recent Accounting Standards

Recently IssuedAdopted Accounting Standards

In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06 to simplify the accounting for certain financial instruments with characteristics of liabilities and equity. The standard eliminates certain accounting models that separated embedded conversion features from host contracts for convertible instruments, requiring bifurcation only if the convertible feature qualifies as a derivative under ASCAccounting Standards Codification ("ASC") 815 or for convertible instruments issued at a substantial premium. In addition, the guidance requires the if-converted method of calculating diluted earnings per share for convertible instruments, which eliminates the use of the treasury stock method for instruments that may be settled in cash or shares. The standard is effective for public business entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. The standard can be adopted on a modified retrospective basis to transactions outstanding as of the adoption date or on a fully retrospective basis to all periods presented. The Company plans to adoptadopted the standard using the modified retrospective method on January 1, 2022. The Company does not expectAdoption of the standard todid not impact the Consolidated Financial Statements as all currently outstandingof the Company’s convertible instruments will maturewere settled prior to the adoption date. See Note 8. Borrowings for detail on the Company's outstanding convertible instruments.instruments that matured on November 1, 2021.

3.25% Convertible Senior Notes Due November 1, 2021

In May 2016, the Company issued $172.5 million aggregate principal amount of 3.25% convertible senior notes due November 1, 2021 ("the Notes"), unless earlier repurchased by the Company or converted pursuant to their terms. Interest is payable semiannually in arrears on May 1 and November 1 each year and commenced on November 1, 2016.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)
The Notes are governed by an Indenture (the "Indenture") between the Company, as issuer, and U.S. Bank National Association as trustee. Upon conversion, the Company will pay or deliver cash, shares of the Company's common stock, or a combination of cash and shares of common stock, at the Company's election. The Company’s current intent is to settle the principal amount of the Notes in cash at maturity. The initial conversion rate is 54.2741 shares of common stock per $1,000 principal amount of Notes. The initial conversion price is $18.4250 per share of common stock. The conversion rate will be subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest. In addition, upon the occurrence of a make-whole fundamental change (as defined in the Indenture), the Company may be required, in certain circumstances, to increase the conversion rate by a number of additional shares for a holder that elects to convert its Notes in connection with such make-whole fundamental change.

Prior to the close of business on the business day immediately preceding August 1, 2021, the Notes will be convertible only under the following circumstances:
=during any calendar quarter and only during such calendar quarters, if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;
=during the five business day period after any 10 consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of Notes was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; or
=upon the occurrence of specified corporate events.

On or after August 1, 2021 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their Notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. As of March 31, 2021, no event has occurred that would permit the conversion of the Notes. The Notes are the Company’s senior unsecured obligations.

In accounting for the issuance of the Notes, the Company separated the Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the face value of the Notes as a whole. The excess of the principal amount of the liability component over its carrying amount is amortized to interest expense over the term of the Notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.

In accounting for the transaction costs related to the Notes issuance, the Company allocated the total amount incurred to the liability and equity components based on their relative values. Issuance costs attributable to the liability component, totaling $5.0 million, are being amortized to interest expense over the term of the Notes, and issuance costs attributable to the equity component, totaling $1.3 million, were netted with the equity component in stockholders' equity.

Note Hedges

To minimize the impact of potential economic dilution upon conversion of the Notes, the Company entered into convertible note hedge transactions (the “Note Hedges”) with respect to its common stock. In the second quarter of 2016, the Company paid an aggregate amount of $44.5 million for the Note Hedges. The Note Hedges will expire upon maturity of the Notes. The Note Hedges are intended to offset the potential dilution upon conversion of the Notes and/or offset any cash payments the Company is required to make in excess of the principal amount upon conversion of the Notes in the event that the market value per share of the Company's common stock, as measured under the Note Hedges, is greater than the strike price of the Note Hedges, which initially corresponds to the initial conversion price of the Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the Notes. The Note Hedges are separate transactions entered into by the Company, and are not part of the Notes or the Warrants, and have been accounted for as part of additional paid-in capital. Holders of the Notes do not have any rights with respect to the Note Hedges.

Warrants

In addition to the Note Hedges, in the second quarter of 2016, the Company entered into warrant transactions, whereby the Company sold warrants to acquire shares of the Company's common stock at a strike price of $21.1050 per share (the “Warrants”). The Company received aggregate proceeds of $39.1 million from the sale of the Warrants. If the market price per share of the Company's common stock for the reporting period, as measured under the Warrants, exceeds the strike price of the Warrants, the Warrants could have a dilutive effect on the Company's common stock, unless the Company elects, subject to certain conditions, to settle the Warrants in cash. The Warrants are separate transactions entered into by the Company, and are not part of the Notes or the Note Hedges, and have been accounted for as part of additional paid-in capital. Holders of the Notes and Note Hedges do not have any rights with respect to the Warrants.

Revolving Credit Facility

There were no revolving credit facility borrowings outstanding as of March 31, 2021 and December 31, 2020.

On September 4, 2020, the Company entered into a new Credit Agreement (the "New Credit Agreement"). The New Credit Agreement provides for a senior secured revolving credit facility (the "New Credit Facility") with borrowings in an aggregate principal amount at any time outstanding not to exceed $400.0 million. The New Credit Agreement serves as refinancing of indebtedness and terminates the Company's Revolving Credit Facility Agreement dated as of October 11, 2017 ("Prior Credit Facility"). The Prior Credit Facility consisted of a $400.0 million senior secured revolving credit facility.

At any time during the term of the New Credit Facility, the Company will be permitted to increase the commitments under the New Credit Facility or to establish one or more incremental term loan facilities under the New Credit Facility in an aggregate principal amount not to exceed $200.0 million for all such incremental facilities. Commitments under the New Credit Facility will terminate, and loans outstanding thereunder will mature, on January 2, 2024; provided, that if all the Notes have not been repaid, refinanced, and/or converted to common stock of the Company by August 2, 2021 (the "Springing Maturity Test Date"), then the commitments under the New Credit Facility will terminate, and the loans outstanding thereunder will mature, on such earlier date unless, from and after the Springing Maturity Test Date and for so long as the Notes have not been repaid, refinanced, and/or converted to common stock of the Company, the Company does not maintain liquidity (as defined in the New Credit Agreement) for any period of three consecutive business days of $150.0 million or more.2024.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The New Credit Agreement includes requirements, to be tested quarterly, that the Company maintains (i) a minimum ratio of Consolidated EBITDA to consolidated interest expense of 3.25 to 1.0 (the "Interest Coverage Ratio"), (ii) a maximum ratio of Consolidated total indebtedness to Consolidated EBITDA of 3.75 to 1.0 (the "Total Leverage Ratio"), and (iii) a maximum ratio of senior secured indebtedness to Consolidated EBITDA of 3.25 to 1.0 (the "Senior Secured Leverage Ratio"). For these ratios, Consolidated EBITDA and consolidated interest expense are calculated using the most recent four consecutive fiscal quarters in a manner defined in the New Credit Agreement. At March 31, 2021,2022, the Company was in compliance with these covenants and it expects to remain in compliance with all of its debt covenants over the next twelve months.

The interest rates under the New Credit Facility will be, at the Borrowers' option (1) LIBOR (or in the case ofEURIBOR for borrowings under the New Credit Facility denominated in Euro, EURIBOR)Euro; or SONIA for borrowings denominated in Pounds Sterling) plus the rates per annum determined from time to time based on the total leverage ratio of the Company as of the end of and for the most recent period of four fiscal quarters for which financial statements have been delivered (the "Applicable Margin"); or (2) in the case of borrowings denominated in U.S. dollars, alternate base rate ("ABR") (as defined in the New Credit Agreement) plus the Applicable Margin. The Applicable Margin for LIBOR could range from 1.50% to 2.50% while the Applicable Margin for ABR could range from 0.50% to 1.50%. Prior to the discontinuation of the relevant LIBOR reference rate on June 30, 2023, the Company and its lenders will agree on an ABR to address the replacement of LIBOR for the remaining life of the New Credit Facility.

The interest rate under the New Credit Facility is variable based on LIBOR at the time of the borrowing and the Applicable Margin. In addition, a commitment fee accrues on the average daily unused portion of the New Credit Facility at a rate of 0.225% to 0.375%.

The weighted-average interest rate on the Company's borrowings under the New Credit Facility was 2.12% for the three months ended March 31, 2022. There were no borrowings outstanding under the New Credit Facility during the three months ended March 31, 2021. The weighted-average interest rate on the Company's borrowings under the Prior Credit Facility was 3.09% for the three months ended March 31, 2020.

3.25% Convertible Senior Notes Due November 1, 2021

In May 2016, the Company issued $172.5 million aggregate principal amount of 3.25% convertible senior notes which matured on November 1, 2021 (the “Notes”). Interest was payable semiannually in arrears on May 1 and November 1 of each year. The Notes were governed by an Indenture between the Company, as issuer, and U.S. Bank National Association as trustee. Upon conversion, the Company could elect to pay or deliver cash, shares of the Company's common stock, or a combination of cash and shares of common stock. On November 1, 2021, the Company settled the principal amount of the Notes in cash and the excess conversion value by delivering 0.4 million shares of its common stock held in treasury. The conversion rate was 54.2741 shares of common stock per $1,000 principal amount of Notes. The conversion price was $18.4250 per share of common stock. The Notes were senior unsecured obligations.

In accounting for the issuance of the Notes, the Company separated the Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that did not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the face value of the Notes as a whole. The excess of the principal amount of the liability component over its carrying amount was amortized to interest expense over the term of the Notes.

The Warrants expired during the first quarter of 2022, which resulted in the Company delivering 0.2 million shares of its common stock held in treasury. Settlement of the Warrants resulted in a $3.1 million decrease in treasury stock, which was measured based on the acquisition cost of the delivered shares determined on a first-in, first-out (“FIFO”) basis, offset by an equivalent decrease in additional paid-in capital with no net impact to equity.

10. Income Taxes

Income taxes for the interim periods presented have been included in the accompanying Consolidated Financial Statements on the basis of an estimated annual effective tax rate ("ETR"). The determination of the consolidated provision for income taxes requires management to make certain judgments and estimates. Changes in the estimated level of annual pre-tax earnings or loss, tax laws, and changes resulting from tax audits can affect the overall ETR, which impacts the level of income tax expense or benefit and net income or loss. Judgments and estimates related to the Company’s projections and assumptions are inherently uncertain and therefore, actual results could differ materially from projections.

The Company's ETR from continuing operations for the three months ended March 31, 2022 and 2021 was a 13.8% provision (inclusive of discrete items totaling $1.0 million of benefit) and 2020 was a 17.8% provision (inclusive of discrete items totaling $0.1 million of benefit), respectively. The discrete items impacting the tax provision for the three months ended March 31, 2022 were primarily attributable to the stock-based compensation deduction. Absent the discrete items, the ETR for the three months ended March 31, 2022 and a 20.8%2021 was an 18.6% provision and an 18.4% provision, respectively. The Company accrues taxes in various countries where it generates income and applies a valuation allowance in other jurisdictions, (primarily the U.S.), which resulted in the provision for the three months ended March 31, 20212022 and 2020.2021.

The Company's ETR is favorably impacted by tax holidays granted to the Company in Malaysia effective through December 31, 2021.and China. The Company secured the Chinese tax holiday in the first quarter of 2022. These tax holidays are subject to the Company's annual satisfaction of certain conditions, including investment and sales thresholds. If the Company fails to satisfy such conditions, the Company's ETR may be significantly adversely impacted. The continuing operations benefit of ourthe tax holidays in Malaysia and China for the three months ended March 31, 2022 was approximately $2.6 million, or $0.03 on a basic per share basis. The benefit of these incentives for the three months ended March 31, 2021 was approximately $2.4 million, or $0.03 on a basic per share basis. The continuing operations benefit of these incentives forCompany's existing significant tax holiday in Malaysia will expire on December 31, 2026, while the three months ended Marchtax holiday in China will expire on December 31, 2020 was approximately $1.3 million, or $0.01 on a per share basis.2023.

11. Equity Incentive Program

Stock-based compensation expense recognized in the Consolidated Statements of Earnings totaled $11.1$7.6 million and $3.5$11.1 million for the three months ended March 31, 2022 and 2021, and 2020, respectively. The tax benefit recognized related to stock-based compensation expense was $3.2 million for the three months ended March 31, 2022. No tax benefit was recognized related to stock-based compensation expense for the three months ended March 31, 2021.

Stock Options and SSARs

PSUs

The Company grants performance share units (“PSUs”) to senior management. In each case, the awards will cliff vest three years following the grant date. PSUs will be settled in shares of the Company's common stock. Depending on the Company's overall performance relative to the applicable measures, the size of the PSU awards are subject to adjustment, up or down, resulting in awards at the end of the performance period that can range from 0% to 225% of target. The Company will ratably recognize the expense over the applicable service period for each grant of PSUs and adjust the expense for the expected achievement of performance conditions as appropriate. The fair value of PSUs is determined by using a Monte Carlo simulation. For the awards granted in February 2022 and 2021, the number of PSUs that may be earned and vest is based on total shareholder return (“TSR”) relative to the component companies of the Russell 2000 Index over a three-year performance period.

The COVID-19 pandemic brought on unique and unprecedented challenges to the Company, particularly in the hearing health and medtech markets. Many of the Company's executive compensation programs were affected, including outstanding PSU awards. Due to the impact of the COVID-19 pandemic on the Company’s overall business performance, effective February 8, 2021, the Company’s Compensation Committee approved certain modifications to PSUs granted in February 2018, 2019, and 2020.

For the awards granted in February 2018 (the “2018 PSUs”), the number of PSUs that may be earned and vest was originally based on the Company’s revenues and stock price performance over a three-year performance period. The modified award iswas based on the Company’s revenues and stock price performance over three separate one-year performance periods to isolate the impact of the COVID-19 pandemic on the Company's fiscal 2020 performance. In addition, the performance periods corresponding to fiscal 2018 and 2019 were weighted at 25% each while the performance period corresponding to fiscal 2020 was weighted at 50%, given the impact of fiscal 2020 performance on shareholders. Service conditions were not modified. The modification of the 2018 PSUs affected 9 employees and resulted in total incremental compensation expense of $3.9 million, which was recognized in the first quarter of 2021 as there was no remaining service period. In February 2021, the 2018 PSUs were converted from 329,092 PSUs to 190,544 shares of common stock based on achievement of the modified conditions.

For the awards granted in February 2019 (the “2019 PSUs”), the number of PSUs that may be earned and vest was originally based on the Company's revenues and TSR relative to the component companies of the S&P Semiconductor Select Industry Index over a three-year performance period. The modified award iswas based on the Company’s revenues and TSR relative to the component companies of the S&P Semiconductor Select Industry Index over three separate one-year performance periods to isolate the impact of the COVID-19 pandemic on the Company's fiscal 2020 performance. Each period iswas weighted equally, as the Company expectsexpected to face challenges related to the COVID-19 pandemic in fiscal 2021. Service conditions were not modified. The modification of the 2019 PSUs affected 8 employees and resulted in total incremental compensation expense of $2.4 million, which will bewas recognized over the remaining service period. Incremental compensation expense iswas subject to adjustment for the expected achievement of the performance condition based on fiscal 2021 revenues. In February 2022, the 2019 PSUs were converted from 227,812 PSUs to 150,811 shares of common stock based on achievement of the modified conditions.

For the awards granted in February 2020 (the “2020 PSUs”), the number of PSUs that may be earned and vest was originally based on TSR relative to the component companies of the S&P Semiconductor Select Industry Index over a three-year performance period. The modified award replaces the S&P Semiconductor Select Industry Index with the Russell 2000 Index. The Company is a member of the Russell 2000 Index, which represents a broader, more diversified index that better aligns with the Company's strategy. Service conditions were not modified. The modification of the 2020 PSUs affected 8 employees and resulted in total incremental compensation expense of $4.7 million, which will be recognized over the remaining service period.

The following table summarizes the Company's PSU activity for the three months ended March 31, 2021:

13. Commitments and Contingent Liabilities

From time to time, the Company is involved in various legal proceedings and claims arising in the ordinary course of its business. The majority of these claims and proceedings relate to commercial, warranty, employment, and intellectual property matters. Although the ultimate outcome of any legal proceeding or claim cannot be predicted with certainty, based on present information, including management’s assessment of the merits of the particular claim, the Company believes that apart from the action set forth below, the disposition of these legal proceedings or claims, individually or in the aggregate, after taking into account recorded accruals and the availability and limits of insurance coverage, will not have a material adverse effect on its cash flow, results of operations, or financial condition.

As previously disclosed, the Company is party to a representative action filed in the Superior Court of California, Los Angeles County under the Private Attorneys General Act, Consuelo Andrade, individually and on behalf of other similarly situated vs. Novacap LLC et al. (Case No. 20STCV21805). The complaint was filed on June 5, 2020 and, as amended, alleges that the Company incorrectly calculated overtime rate of pay, incorrectly paid overtime, and provided inaccurate wage statements, to certain non-exempt employees at the Company’s Valencia, California manufacturing facility in violation of California law. The action sought penalties, attorneys' fees, and other relief. After participating in voluntary mediation in February 2021, the parties agreed to a class-wide (except for employees who opt out) settlement, the amount of which was not material to our financial condition, results of operations, or cash flows. This settlement, if approved by the Court, would include settlement of all penalties under the Private Attorneys General Act, the California Labor Code, and other federal and state wage and hour statutes, attorneys’ fees and costs, class representative enhancements, and claims administration fees.

The Company owns many patents and other intellectual property pertaining to its products, technology, and manufacturing processes. Some of the Company's patents have been and may continue to be infringed upon or challenged by others. In appropriate cases, the Company has taken and will take steps to protect and defend its patents and other intellectual property, including through the use of legal proceedings in various jurisdictions around the world. Such steps have resulted in and may continue to result in retaliatory legal proceedings, including litigation or other legal proceedings in various jurisdictions and forums around the world alleging infringement by the Company of patents owned by others. The costs of investigations and legal proceedings relating to the enforcement and defense of the Company’s intellectual property may be substantial. Additionally, in multi-forum disputes, the Company may incur adverse judgments with regard to certain claims in certain jurisdictions and forums while still contesting other related claims against the same opposing party in other jurisdictions and forums.

Intellectual Property Infringement Claims

The Company may, on a limited customer specific basis, provide contractual indemnities for certain losses that arise out of claims that its products infringe on the intellectual property of others. It is not possible to determine the maximum potential amount under these indemnification agreements due to the unique facts and circumstances involved in each particular agreement. Historically, the Company has not made significant payments under such indemnity arrangements. The Company’s legal accruals associated with these indemnity arrangements were not significant at March 31, 20212022 and December 31, 2020.

COVID-19 aUpdate

The COVID-19 pandemic, particularly as it relates to the emergence of new variants of the virus, continues to have widespread, rapidly-evolving, and recommendedunpredictable impacts in the U.S. and international markets. Many countries have continued applying containment and mitigation measures, worldwide. This has resultedresulting in global business disruption, which hasdisruption. These measures have impacted our business operations, results of operations, customer demand, and the productivity of our facilities, particularly in China, Malaysia, and the Philippines.

The resurgence of COVID-19 in China and the related lockdowns has had, and may continue to have, an impact on various aspects of our business. During the first quarter of 2022, demand for some of our products, particularly in our MEMS Microphones product line, was negatively impacted. While we did not experience a similar impact on demand with respect to our hearing health products or in our PD segment, new or prolonged lockdowns may result in an adverse impact on demand across more of our product lines. In addition, while our facilities in China have generally remained operational during the resurgence, we may experience facility closures or increased employee absenteeism if there is continued spread of COVID-19 variants. We took various stepsalso continue to minimizemanage the negative impactongoing impacts of the COVID-19 pandemic on our businesssupply chain challenges that are impacting many industries, and to protect the health and safety of our employees. Such steps included, but were not limited to, significantly reducing employee travel; having office workers work remotely; suspending our share repurchase program; suspending annual wage increases; temporarily reducing salaries of employees, including the CEO and executive team; and reducing the cash compensation of our board of directors. Most restrictions have been lifted at our facilitiesexacerbated by the lockdowns in China, causing shipping and the majority of our office workers have now returned to working on-site. In locations where public health protocols have accommodated returning to work at our facilities, we implemented additional safety measures, including increased frequency in cleaninglogistics challenges, and disinfecting as well as hygiene and social distancing practices. During the third quarter of 2020, as our end markets began to show signs of recovery and we generated better than expected operating cash flow, we reinstated employee salaries including executive management salaries. We also restored the cash compensation for our board of directors and resumed the share repurchase program in the fourth quarter of 2020.limiting component supplies.

The situation related to COVID-19 continues to be complex and rapidly evolving.dynamic. We cannot reasonably estimate the duration of the pandemic or fully ascertain its impact to our future results. As the COVID-19 pandemic evolves, we will continue to actively monitor developments and business conditions and may take further actions that alter business operations as may be required by applicable authorities or that we determine are in the best interests of our employees, customers, suppliers, stockholders, and communities. It is not clear what potential effects any such alterations or modifications may have on our business, including the effects on our financial results. For additional information regarding risks related to COVID-19, please see Item 1A, Risk Factors, in the Annual Report on Form 10-K for the year ended December 31, 2021.

Non-GAAP Financial Measures

In addition to the GAAP financial measures included in this item, we have presented certain non-GAAP financial measures. We use non-GAAP measures as supplements to our GAAP results of operations in evaluating certain aspects of our business, and our executive management team and Board of Directors focus on non-GAAP items as key measures of our performance for business planning purposes. These measures assist us in comparing our performance between various reporting periods on a consistent basis, as these measures remove from operating results the impact of items that, in our opinion, do not reflect our core operating performance. We believe that our presentation of non-GAAP financial measures is useful because it provides investors and securities analysts with the same information that we use internally for purposes of assessing our core operating performance. The Company does not consider these non-GAAP financial measures to be a substitute for the information provided by GAAP financial results. For a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures, see the reconciliation included herein.

Provision for Income Taxes and Non-GAAP Provision for Income Taxes

The effective tax rate ("ETR") from continuing operations for the first quarter of 2022 and 2021 was a 13.8% provision (inclusive of discrete items totaling $1.0 million of benefit) and a 17.8% provision compared with a 20.8%(inclusive of discrete items totaling $0.1 million of benefit), respectively. The discrete items impacting the first quarter of 2022 tax provision are primarily attributable to the stock-based compensation deduction. Absent the discrete items, the ETR for the first quarter of 2020.2022 and 2021 was an 18.6% provision and an 18.4% provision, respectively. The Company accrues taxes in various countries where it generates income and applies a valuation allowance in other jurisdictions, (primarily the U.S.), which resulted in the provision for both the first quarter of 20212022 and 2020.2021. The change in the ETR was due to the mix of earnings and losses by taxing jurisdictions and net discrete items.

(1) In addition to the GAAP financial measures included herein, Knowles has presented certain non-GAAP financial measures that exclude certain amounts that are included in the most directly comparable GAAP measures. Knowles believes that non-GAAP measures are useful as supplements to its GAAP results of operations to evaluate certain aspects of its operations and financial performance, and its management team primarily focuses on non-GAAP items in evaluating Knowles' performance for business planning purposes. Knowles also believes that these measures assist it with comparing its performance between various reporting periods on a consistent basis, as these measures remove from operating results the impact of items that, in Knowles' opinion, do not reflect its core operating performance. Knowles believes that its presentation of non-GAAP financial measures is useful because it provides investors and securities analysts with the same information that Knowles uses internally for purposes of assessing its core operating performance.
(2)    Production transfer costs represent duplicate costs incurred to migrate manufacturing to facilities primarily in Asia. These amounts are included in the corresponding Gross profit and Earnings (loss) from continuing operations before interest and income taxes for each period presented.
(3)    In 2021, Other expenses represent the ongoing net lease cost (income) related to facilities not used in operations. In 2020, Other expenses represent expenses related to shareholder activism.
(4)(3)    Under GAAP in effect for the Company through 2021, certain convertible debt instruments that may be settled in cash (or other assets) upon conversion arewere required to be separately accounted for as liability (debt) and equity (conversion option) components of the instrument in a manner that reflectsreflected the issuer’s nonconvertible debt borrowing rate. Accordingly, for GAAP purposes we arewere required to recognize imputed interest expense on the Company’s $172.5 million of convertible senior notes due November 1, 2021 that were issued in a private placement in May 2016. The imputed interest rate is 8.12% for the convertible notes due 2021,was 8.12%, while the actual coupon interest rate of the notes was 3.25%. The difference between the imputed interest expense and the coupon interest expense iswas excluded from management’s assessment of the Company’s operating performance because management believes that this non-cash expense iswas not indicative of its core, ongoing operating performance.
(5)(4)    Income tax effects of non-GAAP reconciling adjustments are calculated using the applicable tax rates in the jurisdictions of the underlying adjustments.
(6)(5)    The non-GAAP reconciling adjustments are those adjustments made to reconcile Earnings (loss) from continuing operations before interest and income taxes to Adjusted earnings from continuing operations before interest and income taxes.
(7)(6)    The number of shares used in the diluted per share calculations on a non-GAAP basis excludes the impact of stock-based compensation expense expected to be incurred in future periods and not yet recognized in the financial statements, which would otherwise be assumed to be used to repurchase shares under the GAAP treasury stock method. In addition, the Company entered into convertible note hedge transactions that expired upon maturity of the convertible notes to offset any potential dilution from the convertible notes. Although the anti-dilutive impact of the convertible note hedges iswas not reflected under GAAP, the Company includesincluded the anti-dilutive impact of the convertible note hedges in non-GAAPnon-GAAP diluted average shares outstanding, if applicable.

Liquidity and Capital Resources

Historically, we have generated and expect to continue to generate positive cash flow from operations. Our ability to fund our operations and capital needs will depend on our ongoing ability to generate cash from operations and access to capital markets. We believe that our future cash flow from operations and access to capital markets will provide adequate resources to fund our working capital needs, capital expenditures, strategic investments, and share repurchases. We have secured a revolving line of credit in the United States from a syndicate of commercial banks to provide additional liquidity. Furthermore, if we were to require additional cash above and beyond our cash on the balance sheet, the free cash flow generated by the business, and availability under our revolving credit facility, we would most likely seek to raise long-term financing through the U.S. debt or bank markets.

InDue to the global nature of our operations, a significant portion of our cash is generated and typically held outside the United States. Our cash and cash equivalents totaled $50.7 million and $68.9 million at March 31, 2022 and December 31, 2021, respectively. Of these amounts, cash held by our non-U.S. operations totaled $45.6 million and $64.9 million as of March 31, 2022 and December 31, 2021, respectively. To the extent we repatriate these funds to the U.S., we may be required to pay U.S. state income taxes and applicable foreign withholding taxes on those amounts during the period when such repatriation occurs. Management will continue to reassess our need to repatriate the earnings of our foreign subsidiaries.

On May 2016,3, 2021, we sold $172.5 millionacquired all of the outstanding shares of common stock of IMC for $81.4 million. The acquired business provides RF filters to the defense, industrial, and communications markets. The acquisition's operations are included in the PD segment. For additional information, refer to Note 3. Acquisition to our Consolidated Financial Statements.

On September 4, 2020, we entered into a new Credit Agreement (the "New Credit Agreement"), which provides for a senior secured revolving credit facility (the "New Credit Facility") with borrowings in an aggregate principal amount at any time outstanding not to exceed $400.0 million. As of 3.25% convertible senior notes due November 1, 2021 ("March 31, 2022, outstanding borrowings under the Notes") and concurrently entered into convertible note hedge transactions with respect to our common stock to minimizeNew Credit Facility were $70.0 million. At any time during the potential dilution upon conversionterm of the Notes. The Company’s current intent isNew Credit Facility, we will be permitted to settleincrease the commitments under the New Credit Facility or to establish one or more incremental term loan facilities under the New Credit Facility in an aggregate principal amount ofnot to exceed $200.0 million for all such incremental facilities. Commitments under the Notes in cash at maturity. In addition, we entered into warrant transactions whereby we sold warrants to acquire shares of our common stock at a strike price of $21.1050 per share. The NotesNew Credit Facility will terminate, and loans outstanding thereunder will mature, in 2021, unless earlier converted. The Notes are unsecured, senior obligations and interest is payable semi-annually in arrears. The Notes will be convertible into cash, shares of our common stock, or a combination thereof, at our election. We have primarily used the net proceeds to reduce borrowings outstanding.on January 2, 2024. For additional information, refer to Note 8. Borrowings to our Consolidated Financial Statements.

On February 24, 2020, we announced that our Board of Directors had authorized a share repurchase program of up to $100 million of our common stock. On April 28, 2022, we announced that our Board of Directors had increased the authorization by up to $150 million in additional aggregate value. The timing and amount of any shares repurchased will be determined by us based on our evaluation of market conditions and other factors, and will be made in accordance with applicable securities laws in either the open market or in privately negotiated transactions. We are not obligated to purchase any shares under the program, and the program may be suspended or discontinued at any time. The actual timing, number, and share price of shares repurchased will depend on a number of factors, including the market price of our common stock, general market and economic conditions, and applicable legal requirements. Any shares repurchased will be held as treasury stock. The CompanyDuring the three months ended March 31, 2022, we repurchased 313,395 shares of common stock for a total of $6.8 million. We did not repurchase any shares of itsour common stock during the three months ended March 31, 2021.

On September 4, 2020, we entered into a new Credit Agreement (the "New Credit Agreement"). The New Credit Agreement provides for a senior secured revolving credit facility (the "New Credit Facility") with borrowings in an aggregate principal amount at any time outstanding not to exceed $400.0 million. For additional information, refer to Note 8. Borrowings to our Consolidated Financial Statements.

Our ability to make payments on and to refinance our indebtedness, as well as any debt that we may incur in the future, will depend on our ability in the future to generate cash from operations and financings. Due to the global nature of our operations, a significant portion of our cash is generated and typically held outside the United States. Our cash and cash equivalents totaled $181.6 million and $147.8 million at March 31, 2021 and December 31, 2020, respectively. Of these amounts, cash held by our non-U.S. operations totaled $134.0 million and $101.4 million as of March 31, 2021 and December 31, 2020, respectively.

To the extent we repatriate these funds to the U.S., we may be required to pay U.S. state income taxes and applicable foreign withholding taxes on those amounts during the period when such repatriation occurs. Management will continue to reassess our need to repatriate the earnings of our foreign subsidiaries.

Operating Activities

Cash provided by operating activities adjusts net earnings for certain non-cash items, including depreciation expense, amortization of intangible assets, stock-based compensation, changes in 2021 increased $41.2 milliondeferred income taxes, and the effects of changes in operating assets and liabilities. The decrease in cash provided by operating activities for 2022 as compared to 2020,2021 was primarily due to the unfavorable changes in working capital. The unfavorable changes in working capital in 2022 were primarily driven by the timing of sales and cash collections, an improvementincrease in procurement activity to mitigate supply chain risks, and the timing of payments. In addition, incentive compensation payments were larger in 2022 when compared to 2021. These unfavorable changes in working capital were partially offset by an increase in net earnings which was largely driven by higher revenues, improved gross profit margins, and lower operating expenses. In addition, cash provided by the net sum of favorable changes in accounts payable, inventories, and accounts receivable were higher in the first quarter of 20212022 as compared to the first quarter of 2020.2021.

Investing Activities

The cash used in investing activities during 2022 and 2021 was primarily driven by capital expenditures to support product innovation and cost savings. The cash used in investing activities during 2020 was driven by capital expenditures to support our manufacturing capacity expansion.

In 2021,2022, we expect capital expenditures to be in the range of 5.0%4% to 7.0%6% of revenues.

Financing Activities

Cash used in financing activities during 2022 was primarily related to the $6.8 million of repurchases of common stock and the $6.1 million payment of taxes related to net share settlement of equity awards, partially offset by proceeds of $3.9 million from the exercise of options. Cash provided by financing activities during 2021 iswas primarily related to the net proceeds of $8.4 million from the exercise of options, partially offset by the $6.6 million payment of taxes related to net share settlement of equity awards. Cash provided by financing activities during 2020 is primarily related to the borrowings under our revolving credit facility of $100.0 million, partially offset by the $15.0 million of repurchases of common stock and the $5.8 million payment of taxes related to net share settlement of equity awards.

Contingent Obligations

We are involved in various legal proceedings, claims, and investigations arising in the ordinary course of business. Legal contingencies are discussed in Note 13. Commitments and Contingent Liabilities to our Consolidated Financial Statements.

Borrowings

Commitments under the New Credit Facility will terminate, and loans outstanding thereunder will mature, on January 2, 2024; provided, that if all the Notes have not been repaid, refinanced, and/or converted to our common stock by August 2, 2021 (the "Springing Maturity Test Date"), then the commitments under the New Credit Facility will terminate, and the loans outstanding thereunder will mature, on such earlier date unless, from and after the Springing Maturity Test Date and for so long as the Notes have not been repaid, refinanced, and/or converted to our common stock, we do not maintain liquidity (as defined in the New Credit Agreement) for any period of three consecutive business days of $150.0 million or more.

The interest rate under the New Credit Facility is variable based on LIBOR at the time of the borrowing and our total leverage ratio. Based upon our total leverage ratio, our borrowing rate could range from LIBOR + 1.50% to LIBOR + 2.50%. In addition, a commitment fee accrues on the average daily unused portion of the New Credit Facility at a rate of 0.225% to 0.375%. At March 31, 2021, we were in compliance with all covenants under these facilities.

Critical Accounting Policies and Estimates

This discussion and analysis of results of operations and financial condition is based on our Consolidated Financial Statements, which have been prepared in conformity with U.S. GAAP. The preparation of these financial statements requires the use of estimates and assumptions related to the reporting of assets, liabilities, revenues, expenses, and related disclosures. In preparing these financial statements, we have made our best estimates and judgments of certain amounts included in the financial statements. Estimates are revised periodically. Actual results could differ from these estimates.

The information concerning our critical accounting policiesestimates can be found under Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 20202021 filed with the Securities and Exchange Commission on February 10, 2021.9, 2022. There are no material changes in our previously reported critical accounting policies.estimates.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

During the three months ended March 31, 2021,2022, there were no material changes to the information on market risk exposure disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020.2021. For a discussion of our exposure to market risk as of December 31, 2020,2021, refer to Item 7A, Quantitative and Qualitative Disclosures about Market Risk, contained in our Annual Report on Form 10-K for the year ended December 31, 2020.2021.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management has evaluated, under the supervision and with the participation of our chief executive officer ("CEO") and chief financial officer ("CFO"), the effectiveness of 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")) as of the end of the period covered by this report. Based on that evaluation, our CEO and CFO have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures are effective in ensuring that information required to be disclosed in our Exchange Act reports is (1) recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and (2) accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting
There has been no change in our internal control over financial reporting that occurred during the first quarter of 20212022 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including the CEO and CFO, do not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, will be detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by intentionally falsified documentation, by collusion of two or more individuals within Knowles or third parties, 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. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.
