1. Basis of Presentation

Description of Business - Knowles Corporation (NYSE:KN) is a market leader and global supplier of advanced micro-acoustic, audio processing, and precision device solutions, serving the mobile consumer electronics, communications, medical, military, aerospace, and industrial markets. The Company uses its leading position in micro-electro-mechanical systems ("MEMS") microphones and strong capabilities in audio processing technologies to optimize audio systems and improve the user experience in mobile, ear, and Internet of Things ("IoT") applications. Knowles is also the leader in acoustics components used in hearing aids and has a strong position in high-end capacitors. The Company's focus on its customers, combined with its unique technology, proprietary manufacturing techniques, rigorous testing, and global scale, enable the Company to deliver innovative solutions that optimize the user experience. References to "Knowles," "the Company," "we," "our," and "us" refer to Knowles Corporation and its consolidated subsidiaries.

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, 2017 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. 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. During the first quarter of 2018, the Company recorded a correcting entry of $0.7 million related to inventory reserves. This item, which increased earnings before income taxes and discontinued operations, is not material to the Consolidated Financial Statements for the historical period in which the error originated and is not expected to be material to the Consolidated Financial Statements for the year ended December 31, 2018. Similarly, and as disclosed in the prior year during the first quarter of 2017, the Company recorded a correcting entry of $1.1 million related to inventory reserves and incentive compensation accruals. These items, which decreased loss before income taxes and discontinued operations, were determined not to be material to the Consolidated Financial Statements for the historical period in which the errors originated and the Consolidated Financial Statements for the year ended December 31, 2017.

On January 19, 2018, the Company acquired substantially all of the assets of Compex Corporation ("Compex"), a capacitors manufacturer. See Note 3. Acquisitions for additional information related to the transaction.

On November 28, 2017, the Company completed its sale of the high-end oscillators business ("Timing Device Business"). In accordance with Accounting Standards Codification ("ASC") 205-20, Presentation of Financial Statements - Discontinued Operations, the results of operations and related assets and liabilities for the Timing Device Business have been reclassified as discontinued operations for all periods presented. See Note 2. Disposed and Discontinued Operations for additional information related to the transaction.

Non-cash Investing Activities - Purchases of property, plant, and equipment included in accounts payable at March 31, 2018 and 2017 were $11.8 million and $3.6 million, respectively. These non-cash amounts are not reflected as outflows to Additions to property, plant, and equipment within investing activities of the Consolidated Statements of Cash Flows for the respective periods.

Reclassifications - Certain amounts in prior periods have been reclassified to conform to the current period presentation. See Note 16. Recent Accounting Standards for additional information.

2. Disposed and Discontinued Operations

Management and the Board of Directors periodically conduct strategic reviews of the Company's businesses.

On November 28, 2017, the Company completed the sale of the Timing Device Business, part of the Precision Devices ("PD") segment, to Microsemi Corporation for $130.0 million, plus purchase price adjustments for a net amount of $133.3 million. The Company recorded a gain of $62.3 million as a result of the sale, which included $0.4 million of gain amounts reclassified from Accumulated other comprehensive loss into earnings related to currency translation adjustments. The purchase price includes $10.0 million held in escrow that will be received nine months from the completion of the sale and is recorded in the Prepaid and other current assets line on the Consolidated Balance Sheets.

On July 7, 2016, the Company completed the sale of its speaker and receiver product line ("Speaker and Receiver Product Line").

The results of operations and financial positions of the Timing Device Business and Speaker and Receiver Product Line have been reclassified to discontinued operations for all periods presented as these disposals represent strategic shifts that have a major effect on the Company's results of operations.

Summarized results of the Company's discontinued operations are as follows:

⁽¹⁾The Company's policy is to not allocate interest expense to discontinued operations unless it is directly attributable to the operations. The results of operations of the Timing Device Business and Speaker and Receiver Product Line did not have any such interest expense in the periods presented.

There were capital expenditures of nil and $0.2 million included in accounts payable at March 31, 2018 and 2017, respectively.

Note 3. Acquisitions

On January 19, 2018, the Company acquired substantially all of the assets of Compex for $16.0 million, plus purchase price adjustments for a net amount of $18.7 million. The asset purchase agreement relating to the acquisition provided for a $0.6 million post-closing working capital adjustment that settled on April 2, 2018 as well as a $1.0 million holdback that will be paid eighteen months from the completion of the acquisition and is recorded in the Other liabilities line on the Consolidated Balance Sheets. The acquired business provides single layer electronic components to the telecommunication, fiber optics, defense, and aerospace markets. The transaction was accounted for under the acquisition method of accounting and the results of operations are included in the Consolidated Financial Statements from the date of acquisition in the PD segment. Included in the Consolidated Statements of Earnings are Compex's revenues and earnings before income taxes of $2.6 million and $0.2 million, respectively, from the date of acquisition through March 31, 2018.



Table of Contents	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The table below represents a preliminary allocation of the purchase price to net assets acquired as of January 19, 2018:



(in millions)
Cash	0.2
Receivables	1.7
Inventories	2.1
Property, plant, and equipment	2.1
Customer relationships	7.3
Unpatented technologies	2.0
Trademarks and other amortized intangible assets	0.4
Other assets	0.2
Goodwill	2.9
Assumed current liabilities	(0.2		)
Total purchase price	$	18.7

The purchase price allocation in the table above is preliminary and subject to the finalization of the Company's valuation analysis.

Compex Intangible Assets Recorded

Customer relationships, unpatented technologies, and trademarks will be amortized over estimated useful lives of 10 years, 8 years, and 5 years, respectively. The fair value for customer relationships was determined using the excess earnings method under the income approach. The fair values of unpatented technologies and trademarks were determined using the relief from royalty method under the income approach. The fair value measurements of intangible assets are based on significant unobservable inputs, and thus represent Level 3 inputs. Significant assumptions used in assessing the fair values of intangible assets include discounted future cash flows, customer attrition rates, and royalty rates.

The excess of the total purchase price over the total fair value of the identifiable assets and liabilities was recorded as goodwill. The goodwill recognized is primarily attributable to the assembled workforce and synergies. None of the goodwill resulting from this acquisition is tax deductible. Goodwill has been allocated to the PD segment, which is the segment expected to benefit from the acquisition.

Impact of Compex Acquisition and Pro-forma Summary

The following unaudited pro-forma summary presents consolidated financial information as if Compex had been acquired on January 1, 2017. The unaudited pro-forma financial information is based on historical results of operations and financial positions of the Company and Compex. The pro-forma results include estimated amortization of definite-lived intangible assets and the estimated depreciation expense of the fixed asset step-up to fair value. The pro-forma results exclude transaction costs and the estimated cost of the inventory step-up to fair value.

8. Hedging Transactions and Derivative Instruments

The Company is affected by changes in certain market conditions. These changes in market conditions may adversely impact the Company’s financial performance and are referred to as "market risks." The Company uses derivatives as a risk management tool to mitigate the potential impact of certain market risks, which are primarily foreign currency risk and interest rate risk related to ongoing business operations.

Cash Flow Hedging

The Company uses cash flow hedges to minimize the variability in cash flows of assets, liabilities, or forecasted transactions caused by fluctuations in foreign currency exchange rates or market interest rates. These derivatives, which are designated cash flow hedges, are carried at fair value. The changes in their fair values are recorded to Accumulated Other Comprehensive Income (Loss) ("AOCI") and reclassified in current earnings when the hedge contract matures or becomes ineffective.



Table of Contents	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	(unaudited)

To manage its exposure to foreign currency exchange rates, the Company has entered into currency deliverable forward contracts. These derivative instruments allow the Company to hedge portions of its forecasted intercompany sales, which are expected to occur within the next twelve months and are denominated in non-functional currencies. The Company maintains a foreign currency cash flow hedging program primarily to reduce the risk that the net U.S. dollar cash inflows from non-U.S. dollar sales and non-U.S. dollar net cash outflows from procurement activities will be adversely affected by changes in foreign currency exchange rates. At March 31, 2018 and December 31, 2017, the notional value of the derivatives related to currency forward contracts, principally the Chinese yuan, Malaysian ringgit, and Philippine peso, was $52.6 million and $17.9 million, respectively.

To manage its exposure to market risk for changes in interest rates, the Company entered into an interest rate swap on November 12, 2014 to convert variable interest rate payments into a fixed rate on a notional amount of $100.0 million of debt for monthly interest payments that began in January 2016 and ends in July 2018. In December 2017, the Company entered into a partial termination of the interest rate swap and reduced the notional amount to $50.0 million. The Company designated the swap as a cash flow hedge with re-measurement gains and losses recorded through AOCI.

Economic (Non-Designated) Hedging

In addition to derivative instruments that are designated and qualify for hedge accounting, the Company also uses certain derivatives as economic hedges of foreign currency risk. Although these derivatives were not designated and/or did not qualify for hedge accounting, they are effectively economic hedges. The changes in fair value of these economic hedges are immediately recognized in earnings.

The Company uses foreign currency economic hedges to offset the earnings impact that fluctuations in foreign currency exchange rates have on certain monetary assets and liabilities denominated in non-functional currencies. The Company does not enter into these hedges for speculative reasons. These derivatives are carried at fair value with changes in fair value immediately recognized in earnings within Other (income) expense, net. In addition, these derivative instruments minimize the impact of exchange rate movements on the Company’s balance sheet, as the gains or losses on these derivatives are intended to offset gains and losses from the reduction of the hedged assets and liabilities. At March 31, 2018 and December 31, 2017, the notional value of the derivatives related to economic hedging was $2.7 million and $6.4 million, respectively.

The notional amounts of the derivative financial instruments do not necessarily represent amounts exchanged by the parties and, therefore, are not a direct measure of our exposure to the financial risks described above. The amounts exchanged are calculated by reference to the notional amounts and by other terms of the derivatives, such as interest rates, foreign currency exchange rates, or other financial indices. The Company does not view the fair values of its derivatives in isolation, but rather in relation to the fair values or cash flows of the underlying hedged transactions or other exposures. Virtually all of our derivatives are straightforward over-the-counter instruments with liquid markets.

Fair Value Measurements

All derivatives are carried at fair value on the Company’s Consolidated Balance Sheets. ASC 820, Fair Value Measurement, establishes a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. ASC 820 establishes three levels of inputs that may be used to measure fair value as follows:

Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities.

Level 3 - Unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The Company determines the fair values of its derivatives based on standard valuation models or observable market inputs such as quoted market prices, foreign currency exchange rates, or interest rates; therefore, the Company classifies the derivatives within Level 2 of the valuation hierarchy.

The Company early adopted Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2017-12 as of January 1, 2018. The standard requires adoption of the amended presentation and disclosure requirements on a prospective basis. With respect to presentation requirements, the Company began presenting the impact of foreign exchange contracts qualifying as cash flow hedges within the Cost of goods sold line on the Consolidated Statements of Earnings as of January 1, 2018. These amounts were classified in the Other (income) expense, net line in prior periods. This change aligns the presentation of the impact of these hedges with the same line on the Consolidated Statements of Earnings that is used to present the earnings effect of the hedged item. With respect to disclosure requirements, the Company has enhanced the tabular disclosures below to align with the standard. See Note 16.

Debt principal payments	$	—	$	—	$	—	$	172.5	$	50.7

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.

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 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, 2018, no event has occurred that would permit the conversion of the Notes. The Notes are the Company’s senior unsecured obligations.



Table of Contents	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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. Additionally, the Company recorded a deferred tax asset of $0.5 million on a portion of the equity component transaction costs which are deductible for tax purposes and immediately recorded a valuation allowance against this deferred tax asset.

The Notes consist of the following:



(in millions)	March 31, 2018			December 31, 2017
Liability component:
Principal	$	172.5		$	172.5
Less debt issuance costs and debt discount, net of amortization	(28.9		)	(30.6		)

⁽¹⁾ There are no required principal payments due until maturity in November 2021.

⁽²⁾ Recorded in the Consolidated Balance Sheets within additional paid-in capital, inclusive of the $1.3 million of issuance costs in equity.

The total estimated fair value of the Notes at March 31, 2018 was $179.5 million. The fair value was determined based on the closing trading price of the Notes as of the last trading day for the first quarter of 2018.

The following table sets forth total interest expense recognized related to the Notes:

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.



Table of Contents	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	(unaudited)

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

Revolving credit facility borrowings consist of the following:



(in millions)	March 31, 2018		December 31, 2017
$400.0 million revolving credit facility due October 2022	$	50.7	$	50.7
Less current maturities ⁽¹⁾	—		—
Long-term portion	$	50.7	$	50.7

⁽¹⁾ There are no required principal payments due until maturity in October 2022.

On October 11, 2017, Knowles entered into a Revolving Credit Facility Agreement (the "New Credit Facility"). The New Credit Facility contains a five -year senior secured revolving credit facility providing for borrowings in an aggregate principal amount at any time outstanding not to exceed $400.0 million. The New Credit Facility serves as refinancing of indebtedness and terminates the Company's Amended and Restated Credit Agreement dated as of January 27, 2014, as amended and restated as of December 31, 2014 and supplemented from time to time (“Prior Credit Facilities”).

The New Credit Facility 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 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 Facility. At March 31, 2018, 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 rate under the New Credit Facility is variable based on LIBOR at the time of the borrowing and the Company’s leverage as measured by a total indebtedness to Consolidated EBITDA ratio. Based upon the Company’s total indebtedness to Consolidated EBITDA ratio, the Company’s borrowing rate could range from LIBOR + 1.25% to LIBOR + 2.25%. In addition, a commitment fee accrues on the average daily unused portion of the New Credit Facility at a rate of 0.20% to 0.35%.

The weighted-average interest rate on the Company's borrowings under the New Credit Facility and Prior Credit Facilities was 3.70% and 3.64% for the three months ended March 31, 2018 and 2017, respectively. The weighted-average interest rate on the Company's borrowings under the New Credit Facility and Prior Credit Facilities for the three months ended March 31, 2018 and 2017 includes interest expense related to the monthly interest rate swap settlements. The weighted-average commitment fee on the revolving line of credit was 0.28% and 0.40% for the three months ended March 31, 2018 and 2017, respectively.

For supplemental cash flow purposes, cash paid for interest was $0.4 million and $1.5 million for the three months ended March 31, 2018 and 2017, respectively.

11. 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 year-to-date ETR deviates from the statutory U.S. federal income tax rate, mainly due to the taxing jurisdictions in which the Company and its foreign subsidiaries generate taxable income or loss, the favorable impact of its significant tax holiday in Malaysia, and judgments as to the realizability of the Company’s deferred tax assets.

The Company's ETR from continuing operations for the three months ended March 31, 2018 and 2017 was a 200.0% provision and a 9.1% benefit, respectively. The changes in ETR were due to the mix of earnings and losses by taxing jurisdictions. The ETR is favorably impacted by two tax holidays granted to the Company in Malaysia effective through December 31, 2021. These tax holidays are subject to the Company's 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 our tax holidays in Malaysia for the three months ended March 31, 2018 was approximately $1.5 million, or $0.02 on a per share basis. The continuing operations expense of these incentives for the three months ended March 31, 2017 was approximately $0.5 million, or $0.01 on a per share basis.

At March 31, 2018, the Company has not completed its accounting for all of the tax effects of the Tax Cuts and Jobs Act (“Tax Reform Act”). As noted in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, the Company was able to reasonably estimate certain effects, and therefore, recorded provisional adjustments associated with the deemed repatriation tax, the change in the beginning of year valuation allowance, and the benefit for the remeasurement of deferred tax assets and liabilities. The Company has not made any additional measurement period adjustments related to these items during the quarter. The Internal Revenue Service (“IRS”) issued interpretive guidance related to the deemed repatriation tax on April 2, 2018 in Notice 2018-26. The Company is in the process of fully evaluating the guidance and will account for the effects of this new guidance in the period of issuance, the second quarter of 2018. Based on an initial review of the notice, the Company does not expect it to result in a material change to the provisional liability previously recorded. The Company continues to gather additional information to complete the accounting for these items and expects to complete the accounting within the prescribed Staff Accounting Bulletin No. 118 (“SAB 118”) measurement period, which is no later than the fourth quarter of 2018.

12. Equity Incentive Program

Stock-based compensation expense recognized in the Consolidated Statements of Earnings totaled $7.0 million and $5.9 million for the three months ended March 31, 2018 and 2017, respectively.

There was no unrecognized compensation expense related to SSARs at March 31, 2018. At March 31, 2018, unrecognized compensation expense related to stock options not yet exercisable was $10.1 million and is expected to be recognized over a weighted-average period of 1.5 years.

RSUs

The following table summarizes the Company's restricted stock unit ("RSU") balances for the three months ended March 31, 2018:

At March 31, 2018, $37.3 million of unrecognized compensation expense related to RSUs is expected to be recognized over a weighted-average period of 1.6 years.

PSUs

In February 2018 and 2017, the Company granted performance stock units ("PSUs") to senior management. In each case, the awards will cliff vest three years following the grant date and the number of PSUs that may be earned and vest is based on the Company's revenues and stock price performance over a three year performance period. PSUs will be settled in shares of the Company's common stock. Depending on the Company's overall performance relative to revenues and stock price performance, 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 the initial grant value. The Company will ratably recognize the expense over the applicable service period for each grant of PSUs and adjust the expense as appropriate. The fair value of the PSUs is determined by using a Monte Carlo simulation.

14. 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, including those related to intellectual property, which may be owned by it or others. The Company owns many patents and other intellectual property pertaining to its products, technology, and manufacturing processes. Some of its patents have been and may continue to be infringed 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, particularly multi-forum litigation, 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. 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 does not expect that any asserted or unasserted legal proceedings or claims, individually or in the aggregate, will have a material adverse effect on its cash flow, results of operations, or financial condition.

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. Historically, the Company has not made significant payments under such indemnity arrangements. The Company’s legal accruals were not significant at March 31, 2018 and December 31, 2017.

16. Recent Accounting Standards

Recently Issued Accounting Standards

In February 2018, the FASB issued ASU 2018-02, which allows the reclassification from accumulated other comprehensive income to retained earnings of stranded tax effects resulting from the Tax Reform Act. The standard also requires certain disclosures concerning stranded tax effects regardless of the election with respect to stranded tax effects resulting from the Tax Reform Act. The standard is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The standard should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effects of the Tax Reform Act were recognized. The Company has not yet determined whether it will reclassify stranded tax effects resulting from the Tax Reform Act. The impact of the reclassification, if elected, would not be significant. The Company plans to adopt this standard on January 1, 2019.

In February 2016, the FASB issued ASU 2016-02, which requires a lessee to recognize a lease liability and asset for all leases, including operating leases, with a term greater than 12 months on its balance sheet. The standard requires a modified retrospective transition method for all entities. This ASU also provides clarification surrounding the presentation of the effects of leases in the statement of earnings and statement of cash flows. This standard is effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The Company has established a project plan and is evaluating its lease portfolio to assess the impact on its Consolidated Financial Statements as well as on its accounting processes, internal controls, and disclosures. The Company has not yet determined the impact of the standard on its Consolidated Financial Statements. The Company plans to adopt the standard on January 1, 2019.

Recently Adopted Accounting Standards

In August 2017, the FASB issued ASU 2017-12 with the objective of improving the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and simplify the application of hedge accounting guidance. The standard is effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The standard requires adoption on a modified retrospective basis for hedging relationships existing as of the adoption date and on a prospective basis for the amended presentation and disclosure requirements.



Table of Contents	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	(unaudited)

The Company elected to early adopt the standard as of January 1, 2018. Adoption of the standard did not result in a cumulative effect adjustment to retained earnings as of January 1, 2018 as the Company had no cumulative ineffectiveness recognized under its hedging relationships existing as of the adoption date. See Note 8. Hedging Transactions and Derivative Instruments for detail on the Company's prospective adoption of the amended presentation and disclosure requirements. The adoption of this standard had no other impact on the Consolidated Financial Statements.

In May 2017, the FASB issued ASU 2017-09 that provides guidance about when a change to the terms or conditions of a share-based payment award must be accounted for as a modification. The new guidance requires modification accounting if the fair value, vesting condition, or classification of an award is not the same immediately before and after a change to the terms and conditions of the award. This standard is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company prospectively adopted this guidance on January 1, 2018, which had no impact on the Consolidated Financial Statements.

In March 2017, the FASB issued ASU 2017-07 primarily to improve the presentation of net periodic pension and post-retirement benefit cost. The new guidance requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the statement of earnings separately from the service cost component and outside of any subtotal of operating income. This standard is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company adopted this guidance on January 1, 2018 using a retrospective approach for the presentation of net benefit cost components. For the three months ended March 31, 2018, net benefit income other than service cost of $0.2 million was recognized within the Other expense (income), net line on the Consolidated Statements of Earnings. For the three months ended March 31, 2017, net benefit income other than service cost of $0.1 million previously presented in the Selling and administrative expenses line on the Consolidated Statements of Earnings has been reclassified to the Other expense (income), net line. The adoption of this standard had no other impact on the Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-01, which requires a reporting entity to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or liabilities. This standard is effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company prospectively adopted this guidance on January 1, 2018, which had no impact on the Consolidated Financial Statements.

In August 2016, the FASB issued ASU 2016-15 with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new guidance requires evaluation of cash receipts and payments on the basis of the nature of the underlying cash flows and provides clarity for categorization for specific transactions. This standard is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company retrospectively adopted this guidance on January 1, 2018, which had no impact on the Consolidated Financial Statements.

In January 2016, the FASB issued ASU 2016-01, which requires a company to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk if the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. This standard is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company adopted this guidance on a modified retrospective basis as of January 1, 2018, which had no impact on the Consolidated Financial Statements.

In May 2014, the FASB issued ASU 2014-09 and issued subsequent amendments to the initial guidance within ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12, and ASU 2016-20, which are collectively referred to as "ASC 606." The core principal of the guidance is to provide a comprehensive revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts. The standard is effective for annual and interim periods beginning after December 15, 2017.



Table of Contents	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	(unaudited)

On January 1, 2018, the Company adopted ASC 606 using the modified retrospective (cumulative effect) transition method. Under this transition method, results for reporting periods beginning January 1, 2018 or later are presented under ASC 606, while prior period results continue to be reported in accordance with previous guidance. The Company did not recognize a cumulative effect adjustment to retained earnings as of January 1, 2018 as the impact of the standard on the Consolidated Financial Statements was not material. As described below, the analysis of contracts under ASC 606 supports the recognition of revenue at a point in time, resulting in revenue recognition timing that is materially consistent with our historical practice of recognizing revenue when title and risk of loss pass to the customer.

Revenue is recognized when control of the promised goods or services is transferred to the customer in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The majority of the Company’s revenue is generated through the manufacture and sale of a broad range of specialized products and components. For product and component sales, each good sold to a customer typically represents a distinct performance obligation. The Company’s performance obligation to provide goods to a customer is typically satisfied at a point in time upon completion of the shipping process as indicated by the terms of the contract, at which point control is transferred to the customer and revenue is recognized. The Company has no significant arrangements with multiple performance obligations. Remaining performance obligations consist of the aggregate amount of the total transaction price that is unsatisfied or partially satisfied. As of March 31, 2018, our total remaining performance obligations are immaterial.

The terms of a contract or historical business practice can give rise to variable consideration, including customer discounts, rebates, and returns. The Company estimates variable consideration using either the expected value or most likely amount method. We include estimated amounts in the transaction price to the extent it is probable that a significant reversal of revenue will not occur in a subsequent reporting period. Our estimates of variable consideration are based on all reasonably available information (historical, current, and forecasted).

The Company elected to account for shipping and handling activities that occur after control of the related good transfers to the customer as fulfillment activities rather than evaluating such activities as performance obligations. As a result, all shipping and handling costs related to contracts with customers are recognized in the Cost of goods sold line on the Consolidated Statements of Earnings, which is consistent with our historical practice. Additionally, the Company elected to apply the practical expedient allowing incremental costs of obtaining a contract to be expensed as incurred if the amortization period of the resulting asset would have been less than one year. These costs primarily consist of sales commissions and the Company has no such significant costs exceeding the one year limit for applying the practical expedient.

Receivables, net from contracts with customers were $109.8 million and $127.0 million as of March 31, 2018 and January 1, 2018, respectively. See Note 15. Segment Information for disclosures regarding the disaggregation of revenues.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with our Consolidated Financial Statements and related Notes included elsewhere in this Quarterly Report on Form 10-Q.

Overview

We are a market leader and global provider of advanced micro-acoustic, audio processing, and precision device solutions, serving the mobile consumer electronics, communications, medical, military, aerospace, and industrial markets. We use our leading position in micro-electro-mechanical systems ("MEMS") microphones and strong capabilities in audio processing technologies to optimize audio systems and improve the user experience in mobile, ear, and Internet of Things ("IoT") applications. We are also the leader in acoustics components used in hearing aids and have a strong position in high-end capacitors. Our focus on the customer, combined with our unique technology, proprietary manufacturing techniques, rigorous testing, and global scale, enables us to deliver innovative solutions that optimize the user experience. References to "Knowles," the "Company," "we," "our," or "us" refer to Knowles Corporation and its consolidated subsidiaries, unless the context otherwise requires.

We are organized into two reportable segments based on how management analyzes performance, allocates capital, and makes strategic and operational decisions. These segments were determined in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 280 - Segment Reporting and are comprised of (i) Audio and (ii) PD. The segments are aligned around similar product applications serving our key end markets, to enhance focus on end market growth strategies.


•	Audio Segment

Our Audio group designs and manufactures innovative audio products, including microphones and balanced armature speakers, signal processing technologies, and software and algorithms used in applications that serve the mobile, ear, and IoT markets. Locations include the sales, support, and engineering facilities in North America, Europe, and Asia, as well as manufacturing facilities in Asia.


•	PD Segment

Our PD group specializes in the design and delivery of highly engineered capacitors and radio frequency devices ("RF") for technically demanding applications. Our devices are used in applications including power supplies, radar, medical implants, and satellites, primarily serving the industrial, defense, aerospace, medical, telecommunications, and automotive markets. Locations include the sales, support, engineering, and manufacturing facilities in North America, Europe, and Asia.

We sell our products directly to original equipment manufacturers ("OEMs") and to their contract manufacturers and suppliers and to a lesser extent through distributors worldwide.

On January 19, 2018, the Company acquired substantially all of the assets of Compex Corporation for $18.7 million. The acquired business provides single layer electronic components to the telecommunication, fiber optics, defense, and aerospace markets. This acquisition's operations are included in the PD segment. For additional information, refer to Note 3. Acquisitions to our Consolidated Financial Statements.

On November 28, 2017, we completed the sale of the Timing Device Business, part of the PD segment, to Microsemi Corporation for $130.0 million, plus purchase price adjustments for a net amount of $133.3 million. For additional information, refer to Note 2. Disposed and Discontinued Operations to our Consolidated Financial Statements.

On January 11, 2017, we completed an acquisition of certain assets of a capacitors manufacturer for cash consideration of $3.7 million, of which $2.5 million was paid during the first quarter of 2017, with the remaining $1.2 million to be paid in installments from 2018 through the first quarter of 2019. This acquisition's operations are included in the PD segment.

Results of Operations for the Three Months Ended March 31, 2018 compared with the Three Months Ended March 31, 2017

In addition to the GAAP financial measures included herein, 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.

Revenues

Revenues for the first quarter of 2018 were $178.5 million, compared with $168.3 million for the first quarter of 2017, an increase of $10.2 million or 6.1%. PD revenues increased $8.0 million due primarily to higher shipments of capacitor products for the defense, telecommunications, industrial, and medical markets, as well as increased revenues related to our acquisition of Compex Corporation in January 2018. Audio revenues increased $2.2 million due primarily to higher shipments of MEMS microphones to key North American OEMs and a key Korean OEM, partially offset by lower shipments to key Chinese OEMs and lower average selling pricing on mature products.

Cost of Goods Sold

Cost of goods sold ("COGS") for the first quarter of 2018 was $113.2 million, compared with $104.7 million for the first quarter of 2017, an increase of $8.5 million or 8.1%. This increase was primarily due to higher MEMS microphones and capacitor volume, product mix, and unfavorable foreign currency exchange rate changes. The increases were partially offset by the favorable impacts from material cost savings, productivity initiatives, and lower production transfer costs.

Table of Contents

Restructuring Charges

During the first quarter of 2018, we recorded total restructuring charges of $0.4 million within Operating expenses. The restructuring charges consist primarily of actions associated with rationalizing the sales and marketing and research and development workforce.

During the first quarter of 2017, we recorded total restructuring charges of $4.9 million, of which $4.1 million was to transfer certain operations of our hearing health manufacturing to an existing lower-cost Asian manufacturing facility. The remaining charges primarily represent actions associated with lowering operating expenses. Charges of $4.3 million were classified in COGS and charges of $0.6 million were classified as Operating expenses.

Gross Profit and Non-GAAP Gross Profit

Gross profit for the first quarter of 2018 was $65.3 million, compared with $59.3 million for the first quarter of 2017, an increase of $6.0 million or 10.1%. Gross profit margin (gross profit as a percentage of revenues) for the first quarter of 2018 was 36.6%, compared with 35.2% for the first quarter of 2017. The gross profit and margin increases were primarily due to higher MEMS microphones and capacitor volume, favorable impacts from material cost savings, productivity initiatives, and lower restructuring costs in the current period, partially offset by lower average selling prices on mature products and unfavorable foreign currency exchange rate changes.

Non-GAAP gross profit for the first quarter of 2018 was $66.7 million, compared with $65.2 million for the first quarter of 2017, an increase of $1.5 million or 2.3%. Non-GAAP gross profit margin (non-GAAP gross profit as a percentage of revenues) for the first quarter of 2018 was 37.4%, compared with 38.7% for the first quarter of 2017. The non-GAAP gross profit increase was primarily due to higher MEMS microphones and capacitor volume, favorable impacts from material cost savings, and productivity initiatives, partially offset by lower average selling prices on mature products and unfavorable foreign currency exchange rate changes. The non-GAAP gross profit margin decreased slightly primarily due to unfavorable foreign currency exchange rate changes and lower capacity utilization in our microphone business.

Research and Development Expenses

Research and development expenses for the first quarter of 2018 were $24.8 million, compared with $24.0 million for the first quarter of 2017, an increase of $0.8 million or 3.3%. Research and development expenses as a percentage of revenues for the first quarter of 2018 and 2017 were 13.9% and 14.3%, respectively. The increase in research and development expenses was driven by compensation increases, partially offset by lower headcount.

Selling and Administrative Expenses

Selling and administrative expenses for the first quarter of 2018 were $35.8 million, compared with $33.4 million for the first quarter of 2017, an increase of $2.4 million or 7.2%. Selling and administrative expenses as a percentage of revenues for the first quarter of 2018 and 2017 were 20.1% and 19.8%, respectively. The increase in selling and administrative expenses was primarily driven by compensation increases and the acquisition of Compex Corporation, partially offset by lower intangible amortization costs.

Earnings (Loss) and Adjusted Earnings from Continuing Operations Before Interest and Income Taxes

Earnings from continuing operations before interest and income taxes for the first quarter of 2018 was $4.4 million, compared with a loss of $0.3 million for the first quarter of 2017, an increase of $4.7 million. The increase was primarily due to higher gross profit.

Adjusted earnings from continuing operations before interest and income taxes ("Adjusted EBIT") for the first quarter of 2018 was $14.7 million, compared with $14.4 million for the first quarter of 2017, an increase of $0.3 million. Adjusted EBIT margin (adjusted EBIT from continuing operations as a percentage of revenues) for the first quarter of 2018 was 8.2%, compared with 8.6% for the first quarter of 2017.

Interest Expense, net

Interest expense for the first quarter of 2018 was $4.0 million, compared with $5.2 million for the first quarter of 2017, a decrease of $1.2 million. The decrease in interest expense is due to lower outstanding borrowings. For additional information on borrowings and interest expense, refer to Note 9. Borrowings to our Consolidated Financial Statements.

Table of Contents

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

The effective tax rate ("ETR") from continuing operations for the first quarter of 2018 was a 200.0% provision, compared with a 9.1% benefit for the first quarter of 2017. The change in the ETR was due to the mix of earnings and losses by taxing jurisdictions.

The non-GAAP ETR from continuing operations for the first quarter of 2018 was a 12.3% provision, compared with a 6.6% provision for the first quarter of 2017. The change in the non-GAAP ETR was due to the mix of earnings by taxing jurisdictions.

The ETR and non-GAAP ETR deviate from the statutory U.S. federal income tax rate, mainly due to the taxing jurisdictions in which we generate taxable income or loss, the favorable impact of our significant tax holidays in Malaysia, and judgments as to the realizability of our deferred tax assets. A significant portion of our pre-tax income is subject to a lower tax rate as a result of our Malaysian tax holidays, subject to our satisfaction of certain conditions we expect to continue to satisfy. Unless extended or renegotiated, our existing significant tax holiday in Malaysia will expire on December 31, 2021. For additional information on these tax holidays, refer to Note 11. Income Taxes to our Consolidated Financial Statements.

At March 31, 2018, we have not completed our accounting for all of the tax effects of the Tax Cuts and Jobs Act (“Tax Reform Act”). As noted in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, we were able to reasonably estimate certain effects, and therefore, recorded provisional adjustments associated with the deemed repatriation tax, the change in the beginning of year valuation allowance, and the benefit for the remeasurement of deferred tax assets and liabilities. We have not made any additional measurement period adjustments related to these items during the quarter. The Internal Revenue Service (“IRS”) issued interpretive guidance related to the deemed repatriation tax on April 2, 2018 in Notice 2018-26. We are in the process of fully evaluating the guidance and will account for the effects of this new guidance in the period of issuance, the second quarter of 2018. Based on an initial review of the notice, we do not expect it to result in a material change to the provisional liability previously recorded. We continue to gather additional information to complete our accounting for these items and expect to complete our accounting within the prescribed Staff Accounting Bulletin No. 118 (“SAB 118”) measurement period, no later than the fourth quarter of 2018.

Earnings from Discontinued Operations, net

Earnings from discontinued operations was $0.1 million for the first quarter of 2018, compared with $1.8 million for the first quarter of 2017. The change in discontinued operations was primarily driven by the sale of our Timing Device Business on November 28, 2017 and the recording of income tax benefits in the prior year.

Diluted Loss per Share from Continuing Operations and Non-GAAP Diluted Earnings per Share from Continuing Operations

Diluted loss per share from continuing operations was $0.00 for the first quarter of 2018, compared with a diluted loss per share of $0.06 for the first quarter of 2017. The improvement in diluted loss per share was mainly driven by higher EBIT.

Non-GAAP diluted earnings per share from continuing operations was $0.11 for the first quarters of 2018 and 2017.

⁽¹⁾ In addition to the GAAP financial measures included herein, Knowles has presented certain non-GAAP financial measures. Knowles believes that non-GAAP measures are useful supplements to its GAAP results of operations in evaluating 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. The Company does not consider these non-GAAP financial measures to be a substitute for the information provided by GAAP financial results.

⁽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 2018, Other represents expenses related to the acquisition of Compex Corporation. In 2017, Other primarily represents expenses related to the acquisition of certain assets of a capacitors manufacturer.

⁽⁴⁾ Under GAAP, certain convertible debt instruments that may be settled in cash (or other assets) upon conversion are required to be separately accounted for as liability (debt) and equity (conversion option) components of the instrument in a manner that reflects the issuer’s nonconvertible debt borrowing rate. Accordingly, for GAAP purposes we are required to recognize imputed interest expense on the Company’s $172.5 million of convertible senior notes due 2021 that were issued in a private placement in May 2016. The imputed interest rate is 8.12% for the convertible notes due 2021, while the actual coupon interest rate of the notes was 3.25%. The difference between the imputed interest expense and the coupon interest expense is excluded from management’s assessment of the Company’s operating performance because management believes that this non-cash expense is not indicative of its core, ongoing operating performance.

⁽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.

⁽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.

Segment Results of Operations for the Three Months Ended March 31, 2018 compared with the Three Months Ended March 31, 2017

The following is a summary of the results of operations of our two reportable segments: Audio and PD.

See Note 15. Segment Information to the Consolidated Financial Statements for (i) a reconciliation of segment revenues to our consolidated revenues and (ii) a reconciliation of segment earnings from continuing operations before interest and income taxes to our consolidated net earnings (loss) from continuing operations.

⁽¹⁾Production transfer costs represent duplicate costs incurred to migrate manufacturing to facilities in Asia. These amounts are included in earnings from continuing operations before interest and income taxes for each period presented.

Revenues

Audio revenues were $146.4 million for the first quarter of 2018, compared with $144.2 million for the first quarter of 2017, an increase of $2.2 million or 1.5%. Revenues increased due primarily to higher shipments of MEMS microphones to key North American OEMs and a key Korean OEM, partially offset by lower shipments to key Chinese OEMs and lower average selling pricing on mature products.

Earnings and Adjusted Earnings from Continuing Operations Before Interest and Income Taxes

Earnings from continuing operations before interest and income taxes was $12.3 million for the first quarter of 2018, compared with $8.9 million for the first quarter of 2017, an increase of $3.4 million. EBIT margin (EBIT from continuing operations as a percentage of revenues) for the first quarter of 2018 was 8.4%, compared to 6.2% for the first quarter of 2017. The increase was primarily due to higher gross profit as a result of lower restructuring costs in the current period, favorable impacts from material cost savings, productivity initiatives, and higher MEMS microphones shipments, partially offset by lower average selling prices on mature products and unfavorable foreign currency exchange rate changes.

Adjusted EBIT was $17.9 million for the first quarter of 2018, compared with $19.9 million for the first quarter of 2017, a decrease of $2.0 million. Adjusted EBIT margin for the first quarter of 2018 was 12.2%, compared to 13.8% for the first quarter of 2017. The decrease was primarily due to lower average selling prices on mature products and unfavorable foreign currency exchange rate changes, partially offset by favorable impacts from material cost savings, productivity initiatives, and higher MEMS microphones shipments.

Revenues

PD revenues were $32.1 million for the first quarter of 2018, compared with $24.1 million for the first quarter of 2017, an increase of $8.0 million or 33.2%. Revenues increased due primarily to higher shipments of capacitor products for the defense, telecommunications, industrial, and medical markets, as well as increased revenues related to our acquisition of Compex Corporation in January 2018.

Earnings and Adjusted Earnings Before Interest and Income Taxes

PD EBIT was $6.2 million for the first quarter of 2018, compared with $4.3 million for the first quarter of 2017, an increase of $1.9 million. EBIT margin for the first quarter of 2018 was 19.3%, compared to 17.8% for the first quarter of 2017. The increases were primarily due to higher gross profit as a result of increased shipments and favorable impacts from productivity initiatives, partially offset by higher operating costs as it relates to our acquisition of Compex Corporation.

PD Adjusted EBIT was $7.4 million for the first quarter of 2018, compared with $4.7 million for the first quarter of 2017, an increase of $2.7 million. Adjusted EBIT margin for the first quarter of 2018 was 23.1%, compared with 19.5% for the first quarter of 2017. The increases were primarily due to higher gross profit as a result of increased shipments and favorable impacts from productivity initiatives, partially offset by higher operating costs as it relates to our acquisition of Compex Corporation.

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, dividends (if any), capital expenditures, and strategic investments. 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.

In May 2016, we sold $172.5 million aggregate principal amount of 3.25% convertible senior notes due November 1, 2021 ("the Notes") and concurrently entered into convertible note hedge transactions with respect to our common stock to minimize the potential dilution upon conversion of the Notes. 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 Notes 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. For additional information, refer to Note 9. Borrowings to our Consolidated Financial Statements.

On January 11, 2017, we completed an acquisition of certain assets of a capacitors manufacturer for cash consideration of $3.7 million, of which $2.5 million was paid during the first quarter of 2017, with the remaining $1.2 million to be paid in installments from 2018 through the first quarter of 2019, less any purchase price adjustments. This acquisition's operations are included in the PD segment. Refer to Note 3. Acquisitions to our Consolidated Financial Statements for additional information.

On October 11, 2017, we entered into the New Credit Facility. Refer to Note 9. Borrowings to our Consolidated Financial Statements for additional information.

On November 28, 2017, the Company completed its sale of the Timing Device Business, part of the PD segment, to Microsemi Corporation for $130.0 million, plus purchase price adjustments for a net amount of $133.3 million. Refer to Note 2. Disposed and Discontinued Operations to our Consolidated Financial Statements for additional information.

On January 19, 2018, the Company acquired substantially all of the assets of Compex Corporation for $18.7 million. The acquired business provides single layer electronic components to the telecommunication, fiber optics, defense, and aerospace markets. See Note 3. Acquisitions to our Consolidated Financial Statements for additional information related to the transaction.

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, financings, and asset sales. Due to the global nature of our operations, a significant portion of our cash is generated and held outside the United States. Our cash and cash equivalents totaled $62.7 million and $111.7 million at March 31, 2018 and December 31, 2017, respectively. Of these amounts, cash held by our non-U.S. operations totaled $55.2 million and $75.7 million as of March 31, 2018 and December 31, 2017, respectively.

As a result of U.S. tax reform, the $75.7 million held by our non-U.S. operations as of December 31, 2017 was subject to current tax in the U.S. in 2017. As of March 31, 2018, we had not repatriated any of these funds to the U.S. However, to the extent we repatriate these funds to the U.S., we will be required to pay income taxes in certain states 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 in 2018 decreased $23.4 million compared to 2017, primarily due to a higher investment in adjusted working capital (a non-GAAP measure calculated as receivables, net of allowances, plus inventories, less accounts payable) of $11.0 million and increased payments to satisfy our other accrued liabilities.

Investing Activities

The cash used in investing activities during 2018 was driven by capital expenditures to support our manufacturing capacity expansion and the acquisition of Compex Corporation. The cash used in investing activities during 2017 was driven by capital expenditures to support our manufacturing capacity expansion and the acquisition of certain assets of a capacitors manufacturer.

In 2018, we expect capital expenditures to be in the range of 7.0% to 10.0% of revenue.

Financing Activities

Cash used in financing activities during 2018 is primarily related the $3.4 million payment of taxes related to net share settlement of equity awards, whereas cash used in financing activities for 2017 was primarily related to to the $3.4 million paid for payment of taxes related to net share settlement of equity awards, partially offset by $2.8 million of proceeds received for option exercises.

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 policies 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, 2017 filed with the Securities and Exchange Commission on February 20, 2018. There are no material changes in our previously reported critical accounting policies.

Recent Accounting Standards

The adoption of recent accounting standards, as included in Note 16. Recent Accounting Standards to our Consolidated Financial Statements, has not had and is not expected to have a significant impact on our revenue, earnings, or liquidity.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

During the three months ended March 31, 2018, 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, 2017. For a discussion of our exposure to market risk as of December 31, 2017, 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, 2017.

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 2018 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.
