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.

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 the sale of its 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 September 30, 2018 and 2017 were $8.0 million and $3.4 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 17. 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 its 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 $135.1 million. The Company recorded a gain of $63.9 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 included $10.0 million held in escrow that was received during the third quarter of 2018 and was previously 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 Speaker and Receiver Product Line had no effect on the Company's results of operations for the three and nine months ended September 30, 2018.

⁽²⁾ 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.

(in millions)	September 30, 2018		December 31, 2017

(in millions)	2018		2017
Depreciation	$	—	$	2.2
Amortization of intangible assets	—		1.1

There were capital expenditures of nil and $0.2 million included in accounts payable at September 30, 2018 and 2017, respectively.

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 accrued expenses 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 $9.5 million and $2.6 million, respectively, from the date of acquisition through September 30, 2018.

The table below represents the final 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	2.0
Customer relationships	7.3
Unpatented technologies	2.0
Trademarks and other amortized intangible assets	0.4
Other assets	0.2
Goodwill	3.0
Assumed current liabilities	(0.2		)
Total purchase price	$	18.7

The Company recorded a purchase price adjustment related to property, plant, and equipment during the nine months ended September 30, 2018, resulting in an increase to goodwill of $0.1 million. The adjustment did not impact the Consolidated Statements of Earnings.

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.

Table of Contents	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	(unaudited)

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.

The unaudited pro-forma financial information does not necessarily represent the results that would have occurred had the acquisition occurred on January 1, 2017. In addition, the unaudited pro-forma information should not be deemed to be indicative of future results.

Other Acquisition

On January 11, 2017, the Company 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. An additional $1.0 million was paid during the nine months ended September 30, 2018, with the remaining $0.2 million to be paid by the first quarter of 2019. This acquisition's operations are included in the PD segment. The financial results of this acquisition were included in our Consolidated Financial Statements beginning January 11, 2017. Pro-forma financial information has not been provided as the acquisition did not have a material impact on the Consolidated Statements of Earnings.

4. Impairments

The Company evaluates long-lived assets for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. During the second quarter of 2017, an updated strategic plan was completed for Audio segment product lines. The updated strategic plan identified a decline of future demand for a specific product line, which indicated projected future cash flows may not be sufficient to recover the carrying value of the associated unpatented technologies and property, plant, and equipment assets. The utilization of undiscounted future cash flows was used to determine recoverability of the long-lived assets. The fair value of the intangibles was determined through the use of discounted cash flows, and the fair value of fixed assets was determined using their liquidation value. As a result of this analysis, the Company concluded that the fair values of these long-lived assets were less than their respective carrying values as of June 30, 2017. The Company recorded total impairment charges of $21.3 million, of which $5.1 million was related to fixed assets and $16.2 million was related to intangible assets. The Company recorded $1.4 million of the charges within Impairment charges in Gross profit and recorded $19.9 million within the Impairment charges line item in Operating expenses within the Consolidated Statements of Earnings.

9. 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.

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 September 30, 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 $51.0 million and $17.9 million, respectively.

12

Table of Contents	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	(unaudited)

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. The Company designated the swap as a cash flow hedge with re-measurement gains and losses recorded through AOCI. 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 interest rate swap ended in July 2018.

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 expense (income), 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 September 30, 2018 and December 31, 2017, the notional value of the derivatives related to economic hedging was $9.0 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 expense (income), 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 17. Recent Accounting Standards for additional information on the adoption of this standard.

Debt principal payments	$	—	$	—	$	—	$	172.5	$	40.7

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.

15

Table of Contents	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	(unaudited)

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 September 30, 2018, 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. 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)	September 30, 2018			December 31, 2017
Liability component:
Principal	$	172.5		$	172.5
Less debt issuance costs and debt discount, net of amortization	(25.3		)	(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 September 30, 2018 was $197.3 million. The fair value was determined based on the closing trading price of the Notes as of the last trading day for the third quarter of 2018.

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

Revolving credit facility borrowings consist of the following:

(in millions)	September 30, 2018		December 31, 2017

Less current maturities (1)	—		—
Long-term portion	$	40.7	$	50.7

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

On October 11, 2017, the Company 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”).

17

Table of Contents	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	(unaudited)

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 September 30, 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 3.48% and 3.68% for the nine months ended September 30, 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 nine months ended September 30, 2018 and 2017 includes interest expense related to the monthly interest rate swap settlements that ended in July 2018. The weighted-average commitment fee on the revolving line of credit was 0.24% and 0.37% for the nine months ended September 30, 2018 and 2017, respectively.

See Note 9. Hedging Transactions and Derivative Instruments for information on derivatives used to manage interest rate risk.

12. 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 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 has been able to reasonably estimate certain tax effects, and has 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. On August 1, 2018, the Internal Revenue Service (“IRS”) released comprehensive proposed regulations on the Section 965 deemed repatriation tax imposed on U.S. persons with foreign earnings accumulated offshore (the "Proposed 965 Regulations"). As a result, the Company has recorded adjustments of $3.1 million and $3.3 million to its provisional amounts during the three and nine months ended September 30, 2018, respectively. The Company continues to gather information to complete its accounting for these provisional items and intends to complete its accounting within the Staff Accounting Bulletin No. 118 (“SAB 118”) measurement period, which is no later than the fourth quarter of 2018.

During the three and nine months ended September 30, 2018, the Company recorded an increase to its uncertain tax positions of $36.0 million due to the resulting consequences of the Tax Reform Act. The Company believes it is reasonably possible that some or all of the uncertain tax position, recorded as a result of consequences of the Tax Reform Act, may be reversed within the next twelve months.

The year-to-date ETR deviates from the statutory U.S. federal income tax rate, primarily due to the Tax Reform Act and its resulting consequences that were accounted for as uncertain tax positions, the taxing jurisdictions where 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 and nine months ended September 30, 2018 was a 170.4% provision and a 143.8% provision, respectively. During the three and nine months ended September 30, 2018, the ETR from continuing operations was impacted by discrete items totaling $39.7 million and $39.9 million of expense, respectively, primarily related to an increase in its uncertain tax positions of $36.0 million due to resulting consequences of the Tax Reform Act and a $3.1 million adjustment to the Company's SAB 118 provisional deemed repatriation tax. Absent the discrete items, the ETR from continuing operations for the three and nine months ended September 30, 2018 was a 13.4% provision and a 17.1% provision, respectively.

The Company's ETR from continuing operations for the three and nine months ended September 30, 2017 was a 29.5% provision and a 71.6% provision, respectively. During the three and nine months ended September 30, 2017, the ETR from continuing operations was impacted by discrete items totaling $0.7 million and $2.8 million of expense, respectively. The Company settled its 2013 pre-spin-off U.S. federal income tax examination during the period and recognized $2.9 million of expense. Additionally, the Company recorded a $0.2 million tax benefit resulting from a reduction to its uncertain tax position reserves. Absent the discrete items, the ETR from continuing operations for the three and nine months ended September 30, 2017 was a 24.8% provision and a 52.7% provision, 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 and nine months ended September 30, 2018 was approximately $7.2 million and $11.3 million, respectively, or $0.08 and $0.13 on a per share basis. The continuing operations benefit of these incentives for the three and nine months ended September 30, 2017 was approximately $7.8 million and $11.7 million, respectively, or $0.09 and $0.13 on a per share basis.

There was no unrecognized compensation expense related to SSARs at September 30, 2018. At September 30, 2018, unrecognized compensation expense related to stock options not yet exercisable of $7.1 million is expected to be recognized over a weighted-average period of 1.3 years.

RSUs

The following table summarizes the Company's restricted stock unit ("RSU") balances for the nine months ended September 30, 2018:

	Share units		Weighted-average grant date fair value
Unvested at December 31, 2017	2,202,576		$	16.54
Granted	1,623,446		14.25

Forfeited	(356,906	)	14.73
Unvested at September 30, 2018	2,487,982		$	15.15

At September 30, 2018, $27.3 million of unrecognized compensation expense related to RSUs is expected to be recognized over a weighted-average period of 1.4 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, 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.

15. 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 September 30, 2018 and December 31, 2017.

17. Recent Accounting Standards

Recently Issued Accounting Standards

In August 2018, the FASB issued ASU 2018-14 to amend disclosure requirements related to defined benefit pension and other postretirement plans. The standard is effective for public business entities for fiscal years beginning after December 15, 2020. Early adoption is permitted and retrospective application of the guidance is required. The Company has not yet determined the impact of the standard on its disclosures or its adoption date.

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 and issued subsequent amendments to the initial guidance within ASU 2018-01, ASU 2018-10, and ASU 2018-11, which are collectively referred to as "ASC 842." This guidance requires a lessee to recognize a lease liability and right-of-use asset for all leases, including operating leases, with a term greater than 12 months. The guidance 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. Prior to the issuance of ASU 2018-11 in July 2018, the standard required a modified retrospective transition method under which the guidance would be applied at the beginning of the earliest comparative period presented in the financial statements. ASU 2018-11 allows entities to elect an additional transition method under which the guidance would be applied as of the adoption date. The Company plans to adopt the standard under this new transition method that will not require the restatement of comparative period financial statements.

25

Table of Contents	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	(unaudited)

The standard includes a number of optional practical expedients that entities may elect to apply. The Company plans to elect the transition package of practical expedients for leases that commenced before the adoption date, which among other things, allows the Company to carry forward historical lease classifications. The Company also plans to elect the practical expedient to not separate nonlease components from lease components, which may increase lease liabilities and right-of-use assets through the inclusion of payments for nonlease components such as maintenance. The Company continues to evaluate other practical expedients and accounting policy elections.

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 impact of adoption will depend on the lease portfolio as of the transition date and the Company's accounting policy elections. The Company expects adoption of the standard will have a material impact on the Consolidated Balance Sheets related to the recognition of lease liabilities and right-of-use assets for operating leases. The Company has not yet determined the other impacts 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. 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 9. 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 and nine months ended September 30, 2018, net benefit income other than service cost of $0.3 million and net benefit cost other than service cost of $0.6 million was recognized within the Other expense (income), net line on the Consolidated Statements of Earnings. For the three months ended September 30, 2017, net benefit income other than service cost of $0.1 million previously presented in the Cost of goods sold line on the Consolidated Statements of Earnings has been reclassified to the Other expense (income), net line. For the nine months ended September 30, 2017, net benefit income other than service cost of $0.1 million previously presented in both the Selling and administrative expenses and Cost of goods sold lines 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.

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 September 30, 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 $132.5 million and $127.0 million as of September 30, 2018 and January 1, 2018, respectively. See Note 16. 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 Accounting Standards Codification 280 - Segment Reporting and are comprised of (i) Audio and (ii) Precision Devices ("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 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.

Import tariffs or other mandates recently imposed or announced by the current U.S. presidential administration have resulted in retaliatory tariffs and could potentially lead to an escalating trade war with other foreign governments. Tariffs already announced and implemented are having an adverse effect on a small percentage of our capacitor products. Although the impact of the current tariffs on the PD segment is not expected to be material for the next quarter or full year, additional tariffs or an escalating trade war could significantly increase the prices on our products or raw materials that are critical to both of our segments, which we may not be able to recover through price increases and adversely affect our future financial performance. For a discussion of the risk relating to tariffs, refer to Part II - Other Information, Item 1A. Risk Factors.

On January 19, 2018, the Company acquired substantially all of the assets of Compex Corporation ("Compex") 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 $135.1 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. An additional $1.0 million was paid during the nine months ended September 30, 2018, with the remaining $0.2 million to be paid by the first quarter of 2019. This acquisition's operations are included in the PD segment.

Results of Operations for the Three Months Ended September 30, 2018 compared with the Three Months Ended September 30, 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 third quarter of 2018 were $236.2 million, compared with $196.0 million for the third quarter of 2017, an increase of $40.2 million or 20.5%. Audio revenues increased $31.2 million primarily due to higher shipments of MEMS microphones and intelligent audio solutions to Chinese OEMs, partially offset by lower average pricing on mature products and lower shipments to a key Korean OEM. PD revenues increased $9.0 million primarily due to higher shipments of capacitor products for the defense and industrial markets, as well as increased revenues related to our acquisition of Compex in January 2018.

Cost of Goods Sold

Cost of goods sold ("COGS") for the third quarter of 2018 was $146.4 million, compared with $121.7 million for the third quarter of 2017, an increase of $24.7 million or 20.3%. This increase was primarily due to higher volume from MEMS microphones, intelligent audio solutions, and capacitor products. In addition, there was lower fixed overhead absorption, higher ramp costs associated with new product launches at our largest customer, and unfavorable foreign currency exchange rate changes, partially offset by material cost savings, productivity initiatives, and lower production transfer costs.

30

Restructuring Charges

During the third quarter of 2018, we recorded total restructuring charges of $0.5 million that were classified as Operating expenses. The restructuring charges consist primarily of actions associated with rationalizing the workforce.

During the third quarter of 2017, we recorded total restructuring charges of $1.1 million. The restructuring charges consist primarily of actions associated with rationalizing the workforce and the residual expenses related to the transfer of certain operations of hearing health manufacturing to an existing, lower-cost Asian manufacturing facility. Charges of $0.2 million were classified as COGS and charges of $0.9 million were classified as Operating expenses.

Gross Profit and Non-GAAP Gross Profit

Gross profit for the third quarter of 2018 was $89.8 million, compared with $74.1 million for the third quarter of 2017, an increase of $15.7 million or 21.2%. Gross profit margin (gross profit as a percentage of revenues) for the third quarter of 2018 was 38.0%, compared with 37.8% for the third quarter of 2017. The gross profit and margin increases were primarily due to higher MEMS microphones, intelligent audio solutions, and capacitor volume. In addition, there was material cost savings, productivity initiatives, and lower production transfer costs, partially offset by lower average pricing on mature products, lower fixed overhead absorption, higher ramp costs associated with new product launches at our largest customer, and unfavorable foreign currency exchange rate changes.

Non-GAAP gross profit for the third quarter of 2018 was $90.7 million, compared with $76.3 million for the third quarter of 2017, an increase of $14.4 million or 18.9%. Non-GAAP gross profit margin (non-GAAP gross profit as a percentage of revenues) for the third quarter of 2018 was 38.4%, compared with 38.9% for the third quarter of 2017. The non-GAAP gross profit increase was primarily due to higher MEMS microphones, intelligent audio solutions, and capacitor volume. In addition, there was material cost savings and productivity initiatives, partially offset by lower average pricing on mature products, lower fixed overhead absorption, higher ramp costs associated with new product launches at our largest customer, and unfavorable foreign currency exchange rate changes. The non-GAAP gross profit margin decrease was primarily due to lower fixed overhead absorption, lower average pricing on mature products, higher ramp costs associated with new product launches at our largest customer, and unfavorable foreign currency exchange rate changes, partially offset by material cost savings and productivity initiatives.

Research and Development Expenses

Research and development expenses for the third quarter of 2018 were $25.2 million, compared with $21.9 million for the third quarter of 2017, an increase of $3.3 million or 15.1%. Research and development expenses as a percentage of revenues for the third quarter of 2018 and 2017 were 10.7% and 11.2%, respectively. The increase in research and development expenses was driven by compensation increases.

Selling and Administrative Expenses

Selling and administrative expenses for the third quarter of 2018 were $34.5 million, compared with $32.0 million for the third quarter of 2017, an increase of $2.5 million or 7.8%. Selling and administrative expenses as a percentage of revenues for the third quarter of 2018 and 2017 were 14.6% and 16.3%, respectively. The increase in selling and administrative expenses was primarily driven by higher compensation and the acquisition of Compex, partially offset by lower legal costs.

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

Earnings before interest and income taxes ("EBIT") from continuing operations for the third quarter of 2018 was $29.3 million, compared with $20.0 million for the third quarter of 2017, an increase of $9.3 million. EBIT margin (EBIT from continuing operations as a percentage of revenues) for the third quarter of 2018 was 12.4%, compared with 10.2% for the third quarter of 2017. The increase in EBIT and EBIT margin was primarily due to higher gross profit, which was partially offset by higher operating expenses due to compensation increases and the acquisition of Compex.

Adjusted earnings before interest and income taxes ("Adjusted EBIT") from continuing operations for the third quarter of 2018 was $38.6 million, compared with $30.1 million for the third quarter of 2017, an increase of $8.5 million. Adjusted EBIT margin (adjusted EBIT from continuing operations as a percentage of revenues) for the third quarter of 2018 was 16.3%, compared with 15.4% for the third quarter of 2017. The increase in Adjusted EBIT was primarily due to higher gross profit, partially offset by higher operating expenses due to compensation increases and the acquisition of Compex. The increase in Adjusted EBIT margin was primarily driven by a 20.5% increase in revenues, partially offset by a 10.4% increase in non-GAAP operating expenses.

31

Interest Expense, net

Interest expense for the third quarter of 2018 was $4.0 million, compared with $5.1 million for the third quarter of 2017, a decrease of $1.1 million. The decrease in interest expense is due to lower outstanding borrowings. For additional information on borrowings and interest expense, refer to Note 10. Borrowings to our Consolidated Financial Statements.

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

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 has been able to reasonably estimate certain tax effects, and has 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. On August 1, 2018, the Internal Revenue Service (“IRS”) released comprehensive proposed regulations on the Section 965 deemed repatriation tax imposed on U.S. persons with foreign earnings accumulated offshore (the "Proposed 965 Regulations"). As a result, the Company recorded a $3.1 million adjustment to its provisional amounts during the third quarter of 2018. The Company continues to gather information to complete its accounting for these provisional items and intends to complete its accounting within the Staff Accounting Bulletin No. 118 (“SAB 118”) measurement period, which is no later than the fourth quarter of 2018.

The effective tax rate ("ETR") from continuing operations for the third quarter of 2018 was a 170.4% provision, compared with a 29.5% provision for the third quarter of 2017. The ETR from continuing operations for the third quarter of 2018 was impacted by a net discrete provision totaling $39.7 million, primarily related to an increase to the Company's uncertain tax positions of $36.0 million due to the resulting consequences of the Tax Reform Act and a $3.1 million adjustment to its SAB 118 provisional deemed repatriation tax. The ETR from continuing operations for the third quarter of 2017 was impacted by a net discrete provision totaling $0.7 million. Absent the discrete items, the ETR from continuing operations for the third quarter of 2018 and 2017 was a 13.4% provision and a 24.8% provision, respectively. The change in the ETR was primarily due to the Tax Reform Act and its resulting consequences that were accounted for as uncertain tax positions and the mix of earnings and losses by taxing jurisdictions.

The non-GAAP ETR from continuing operations for the third quarter of 2018 was an 11.3% provision, compared with a 9.1% provision for the third quarter of 2017. The non-GAAP ETR from continuing operations for the third quarter of 2018 was impacted by a net discrete provision totaling $1.2 million, primarily related to provision to return adjustments. The non-GAAP ETR from continuing operations for the third quarter of 2017 was impacted by a net discrete benefit totaling $1.0 million, primarily comprised of provision to return adjustments. Absent the discrete items, the non-GAAP ETR from continuing operations for the third quarter of 2018 and 2017 was an 8.0% provision and a 12.8% provision, respectively. The change in the non-GAAP ETR was due to the mix of earnings and losses 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 where 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. The ETR is also impacted by the Tax Reform Act and its resulting consequences that were accounted for as uncertain tax positions. 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 12. Income Taxes to our Consolidated Financial Statements.

Earnings from Discontinued Operations, net

Earnings from discontinued operations was $1.6 million for the third quarter of 2018, compared with $5.2 million for the third quarter of 2017. The change in discontinued operations was primarily driven by the sale of our Timing Device Business on November 28, 2017.

32

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

Diluted loss per share from continuing operations was $0.20 for the third quarter of 2018, compared with earnings per share of $0.12 for the third quarter of 2017. The change was mainly driven by higher tax expense, partially offset by higher EBIT.

Non-GAAP diluted earnings per share from continuing operations was $0.34 for the third quarter of 2018, compared with $0.26 for the third quarter of 2017. The increase in Non-GAAP diluted earnings per share was mainly driven by higher adjusted EBIT.

Revenues

Revenues for the nine months ended September 30, 2018 were $603.1 million, compared with $528.7 million for the nine months ended September 30, 2017, an increase of $74.4 million or 14.1%. Audio revenues increased $47.1 million primarily due to higher shipments of MEMS microphones to Chinese OEMs and a key North American OEM. In addition, we had higher shipments of intelligent audio solutions to several key Chinese OEMs, partially offset by lower average pricing on mature products and lower shipments to a key Korean OEM. PD revenues increased $27.3 million primarily due to higher shipments of capacitor products for the defense and industrial markets, as well as increased revenues related to our acquisition of Compex.

Cost of Goods Sold

COGS for the nine months ended September 30, 2018 was $374.7 million, compared with $326.8 million for the nine months ended September 30, 2017, an increase of $47.9 million or 14.7%. This increase was primarily due to higher volume from MEMS microphones, intelligent audio solutions, and capacitor products. In addition, there was lower fixed overhead absorption, unfavorable foreign currency exchange rate changes, and higher ramp costs associated with new product launches at our largest customer, which was partially offset by material cost savings, productivity initiatives, and lower production transfer costs.

34

Impairment Charges

During the nine months ended September 30, 2017, we recorded total impairment charges of $21.3 million, which were related to a specific product line within the Audio segment. We concluded that the projected cash flows from this product line were not sufficient to recover the carrying value of the associated long-lived assets. Impairment charges of $1.4 million were classified as COGS and $19.9 million were classified as Operating expenses. For additional information on impairment of long-lived assets, refer to Note 4. Impairments to our Consolidated Financial Statements.

Restructuring Charges

During the nine months ended September 30, 2018, we recorded total restructuring charges of $1.5 million. The restructuring charges consist primarily of actions associated with rationalizing the workforce. Charges of $0.1 million were classified as COGS and charges of $1.4 million were classified as Operating expenses.

During the nine months ended September 30, 2017, we recorded total restructuring charges of $8.1 million, net of a $0.9 million reversal of previously recorded restructuring charges. The reversal resulted from subsequent developments that impacted the previously estimated amounts. The restructuring charges consist primarily of actions associated with the transfer of certain operations of hearing health manufacturing into an existing, lower-cost Asian manufacturing facility and the actions associated with rationalizing the workforce. Total restructuring charges of $3.9 million were classified in COGS and charges of $4.2 million were classified as Operating expenses.

Gross Profit and Non-GAAP Gross Profit

Gross profit for the nine months ended September 30, 2018 was $228.3 million, compared with $196.6 million for the nine months ended September 30, 2017, an increase of $31.7 million or 16.1%. Gross profit margin for the nine months ended September 30, 2018 was 37.9%, compared with 37.2% for the nine months ended September 30, 2017. The gross profit and margin increases were primarily due to higher MEMS microphones, intelligent audio solutions, and capacitor volume. In addition, there was material cost savings, productivity initiatives, reduced restructuring charges, and lower production transfer costs, partially offset by lower average pricing on mature products, lower fixed overhead absorption, unfavorable foreign currency exchange rate changes, and higher ramp costs associated with new product launches at our largest customer.

Non-GAAP gross profit for the nine months ended September 30, 2018 was $231.6 million, compared with $207.9 million for the nine months ended September 30, 2017, an increase of $23.7 million or 11.4%. Non-GAAP gross profit margin for the nine months ended September 30, 2018 was 38.4%, compared with 39.3% for the nine months ended September 30, 2017. The non-GAAP gross profit increase was primarily due to higher MEMS microphones, intelligent audio solutions, and capacitor volume. In addition, there was material cost savings and productivity initiatives, partially offset by lower average pricing on mature products, lower fixed overhead absorption, unfavorable foreign currency exchange rate changes, and higher ramp costs associated with new product launches at our largest customer. The non-GAAP gross profit margin decrease was primarily due to lower average pricing on mature products, lower fixed overhead absorption, unfavorable foreign currency exchange rate changes, and higher ramp costs associated with new product launches at our largest customer, partially offset by material cost savings and productivity initiatives.

Research and Development Expenses

Research and development expenses for the nine months ended September 30, 2018 were $75.4 million, compared with $70.6 million for the nine months ended September 30, 2017, an increase of $4.8 million or 6.8%. Research and development expenses as a percentage of revenues for the nine months ended September 30, 2018 and 2017 were 12.5% and 13.4%, respectively. The increase in research and development expenses was driven by compensation increases.

Selling and Administrative Expenses

Selling and administrative expenses for the nine months ended September 30, 2018 were $107.4 million, compared with $99.3 million for the nine months ended September 30, 2017, an increase of $8.1 million or 8.2%. Selling and administrative expenses as a percentage of revenues for the nine months ended September 30, 2018 and 2017 were 17.8% and 18.8%, respectively. The increase in selling and administrative expenses was primarily driven by compensation increases and the acquisition of Compex, partially offset by lower intangible amortization costs.

35

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

EBIT for the nine months ended September 30, 2018 was $43.6 million, compared with $0.6 million for the nine months ended September 30, 2017, an increase of $43.0 million. EBIT margin for the third quarter of 2018 was 7.2%, compared with 0.1% for the third quarter of 2017. The increase in EBIT and EBIT margin was primarily due to higher gross profit and the absence of impairment charges in 2018, partially offset by higher operating expenses due to compensation increases and the acquisition of Compex.

Adjusted EBIT for the nine months ended September 30, 2018 was $74.7 million, compared with $59.0 million for the nine months ended September 30, 2017, an increase of $15.7 million. Adjusted EBIT margin (adjusted EBIT from continuing operations as a percentage of revenues) for the nine months ended September 30, 2018 was 12.4%, compared with 11.2% for the nine months ended September 30, 2017. The increase in Adjusted EBIT was primarily due to higher gross profit, partially offset by higher operating expenses due to compensation increases and the acquisition of Compex. The increase in Adjusted EBIT margin was primarily driven by a 14.1% increase in revenues, partially offset by a 7.4% increase in non-GAAP operating expenses.

Interest Expense, net

Interest expense for the nine months ended September 30, 2018 was $12.1 million, compared with $15.4 million for the nine months ended September 30, 2017, a decrease of $3.3 million. The decrease in interest expense is due to lower outstanding borrowings. For additional information on borrowings and interest expense, refer to Note 10. Borrowings to our Consolidated Financial Statements.

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

The Company has not completed its accounting for all of the tax effects of the Tax Reform Act. As noted in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, the Company has been able to reasonably estimate certain tax effects, and has 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 IRS released the Proposed 965 Regulations on August 1, 2018. The Company recorded $3.3 million in adjustments to its provisional amounts during the nine months ended September 30, 2018. The Company continues to gather information to complete its accounting for these provisional items and intends to complete its accounting within the SAB 118 measurement period, which is no later than the fourth quarter of 2018.

The effective tax rate from continuing operations for the nine months ended September 30, 2018 was a 143.8% provision, compared with a 71.6% provision for the nine months ended September 30, 2017. The ETR from continuing operations for the nine months ended September 30, 2018 was impacted by a net discrete provision totaling $39.9 million, primarily related to an increase to the Company's uncertain tax positions of $36.0 million due to the resulting consequences of the Tax Reform Act and a $3.3 million adjustment to its SAB 118 provisional deemed repatriation tax. The ETR from continuing operations for the nine months ended September 30, 2017 was impacted by a net discrete provision totaling $2.8 million. Absent the discrete items, the ETR from continuing operations for the nine months ended September 30, 2018 was a 17.1% provision, compared to a 52.7% provision for the nine months ended September 30, 2017. The change in the ETR was primarily due to the Tax Reform Act and its resulting consequences that were accounted for as uncertain tax positions and the mix of earnings and losses by taxing jurisdictions.

The non-GAAP ETR from continuing operations for the nine months ended September 30, 2018 was an 11.4% provision, compared with a 6.9% provision for the nine months ended September 30, 2017. The non-GAAP ETR from continuing operations for the nine months ended September 30, 2018 was impacted by a net discrete provision totaling $1.5 million, primarily related to provision to return adjustments. The non-GAAP ETR from continuing operations for the nine months ended September 30, 2017 was impacted by a net discrete benefit totaling $2.7 million, primarily comprised of a $1.7 million benefit related to the change in the Company's uncertain tax positions, $1.1 million related to provision to return adjustments, and $0.4 million due to other adjustments partially offset by a $0.5 million expense related to the completion of the Company's 2013 pre-spin-off U.S. federal income tax examination. Absent the discrete items, the non-GAAP ETR from continuing operations for the nine months ended September 30, 2018 was a 9.2% provision, compared to a 12.5% provision for the nine months ended September 30, 2017. The change in the non-GAAP ETR was due to the mix of earnings and losses by taxing jurisdictions.

36

The ETR and non-GAAP ETR deviate from the statutory U.S. federal income tax rate, mainly due to the taxing jurisdictions where 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. The ETR is also impacted by the Tax Reform Act and its resulting consequences that were accounted for as uncertain tax positions. 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 12. Income Taxes to our Consolidated Financial Statements.

Earnings from Discontinued Operations, net

Earnings from discontinued operations was $1.9 million for the nine months ended September 30, 2018, compared with $8.2 million for the nine months ended September 30, 2017. The change in discontinued operations was primarily driven by the sale of our Timing Device Business on November 28, 2017.

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 $0.15 for the nine months ended September 30, 2018 and $0.28 for the nine months ended September 30, 2017. The improvement in diluted loss per share was mainly driven by higher EBIT, partially offset by higher tax expense.

Non-GAAP diluted earnings per share from continuing operations was $0.64 and $0.48 for the nine months ended September 30, 2018 and 2017. The increase in Non-GAAP diluted earnings per share was mainly driven by higher adjusted EBIT.

⁽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 from continuing operations before interest and income taxes for each period presented.

⁽³⁾  In 2018, Other expenses in Gross profit and Operating expenses represent expenses related to acquisitions and the remaining Other expenses represent an adjustment to pre-spin-off pension obligations. 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⁾  Income tax effects of non-GAAP reconciling adjustments are calculated using the applicable tax rates in the jurisdictions of the underlying adjustments. Adjustments are also made to exclude charges related to the provisional impacts of the Tax Reform Act and the resulting consequences that were accounted for as uncertain tax positions.

⁽⁶⁾  The non-GAAP reconciling adjustments are those adjustments made to reconcile Earnings from continuing operations before interest and income taxes to Adjusted earnings from continuing operations before interest and income taxes.

⁽⁷⁾  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.

(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 $199.0 million for the third quarter of 2018, compared with $167.8 million for the third quarter of 2017, an increase of $31.2 million or 18.6%. Revenues increased primarily due to higher shipments of MEMS microphones and intelligent audio solutions to Chinese OEMs, partially offset by lower average pricing on mature products and lower shipments to a key Korean OEM.

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

Earnings from continuing operations before interest and income taxes was $37.5 million for the third quarter of 2018, compared with $28.1 million for the third quarter of 2017, an increase of $9.4 million. EBIT margin (EBIT from continuing operations as a percentage of revenues) for the third quarter of 2018 was 18.8%, compared to 16.7% for the third quarter of 2017. The increase was primarily due to higher gross profit, partially offset by increases in operating expenses. The higher gross profit is primarily due to increased shipments. In addition, there was material cost savings, productivity initiatives, and lower production transfer costs, partially offset by lower average pricing on mature products, lower fixed overhead absorption, higher ramp costs associated with new product launches at our largest customer, and unfavorable foreign currency exchange rate changes.

Adjusted EBIT was $42.4 million for the third quarter of 2018, compared with $34.0 million for the third quarter of 2017, an increase of $8.4 million. Adjusted EBIT margin for the third quarter of 2018 was 21.3%, compared to 20.3% for the third quarter of 2017. The increase was primarily due to higher gross profit, partially offset by increases in operating expenses. The higher gross profit was higher due to increased shipments. In addition, there was material cost savings and productivity initiatives, partially offset by lower average pricing on mature products, lower fixed overhead absorption, higher ramp costs associated with new product launches at our largest customer, and unfavorable foreign currency exchange rate changes.

Revenues

PD revenues were $37.2 million for the third quarter of 2018, compared with $28.2 million for the third quarter of 2017, an increase of $9.0 million or 31.9%. Revenues increased primarily due to higher shipments of capacitor products for the defense and industrial markets, as well as increased revenues related to our acquisition of Compex.

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

PD EBIT was $7.0 million for the third quarter of 2018, compared with $5.1 million for the third quarter of 2017, an increase of $1.9 million. EBIT margin for the third quarter of 2018 was 18.8%, compared to 18.1% for the third quarter of 2017. The increases were primarily due to higher gross profit as a result of increased shipments, partially offset by higher operating expenses due to compensation increases and our acquisition of Compex.

PD Adjusted EBIT was $8.1 million for the third quarter of 2018, compared with $5.6 million for the third quarter of 2017, an increase of $2.5 million. Adjusted EBIT margin for the third quarter of 2018 was 21.8%, compared with 19.9% for the third quarter of 2017. The increases were primarily due to higher gross profit as a result of increased shipments, partially offset by higher operating expenses due to compensation increases and our acquisition of Compex.

Revenues

Audio revenues were $497.2 million for the nine months ended September 30, 2018, compared with $450.1 million for the nine months ended September 30, 2017, an increase of $47.1 million or 10.5%. Revenues increased primarily due to higher shipments of MEMS microphones to Chinese OEMs and a key North American OEM. In addition, we had higher shipments of intelligent audio solutions to several key Chinese OEMs, partially offset by lower average pricing on mature products and lower shipments to a key Korean OEM.

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

Earnings from continuing operations before interest and income taxes was $67.1 million for the nine months ended September 30, 2018, compared with $29.9 million for the nine months ended September 30, 2017, an increase of $37.2 million. EBIT margin (EBIT from continuing operations as a percentage of revenues) for the nine months ended September 30, 2018 was 13.5%, compared to 6.6% for the nine months ended September 30, 2017. The increase was primarily due to the absence of impairment charges in 2018 and higher gross profit. The higher gross profit is primarily a result of increased shipments. In addition, there was material cost savings, productivity initiatives, lower restructuring expenses, and reduced production transfer costs, partially offset by lower average selling prices on mature products, lower fixed overhead absorption, unfavorable foreign currency exchange rate changes, and higher ramp costs associated with new product launches at our largest customer.

Adjusted EBIT was $83.0 million for the nine months ended September 30, 2018, compared with $75.1 million for the nine months ended September 30, 2017, an increase of $7.9 million. Adjusted EBIT margin was 16.7% for the nine months ended September 30, 2018 and 2017. The increase was primarily due to increased shipments.

PD EBIT was $19.6 million for the nine months ended September 30, 2018, compared with $13.6 million for the nine months ended September 30, 2017, an increase of $6.0 million. EBIT margin for the nine months ended September 30, 2018 was 18.5%, compared to 17.3% for the nine months ended September 30, 2017. The increases were primarily due to higher gross profit as a result of increased shipments, partially offset by higher operating expenses due to compensation increases and our acquisition of Compex. In addition, an unfavorable adjustment was recorded to a pre-spin-off pension obligation.

PD Adjusted EBIT was $24.5 million for the nine months ended September 30, 2018, compared with $15.1 million for the nine months ended September 30, 2017, an increase of $9.4 million. Adjusted EBIT margin for the nine months ended September 30, 2018 was 23.1%, compared with 19.2% for the nine months ended September 30, 2017.

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 10. 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. An additional $1.0 million was paid during the nine months ended September 30, 2018, with the remaining $0.2 million to be paid by the first quarter of 2019. 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 10. Borrowings to our Consolidated Financial Statements for additional information.

On November 28, 2017, the Company completed the sale of its Timing Device Business, part of the PD segment, to Microsemi Corporation for $130.0 million, plus purchase price adjustments for a net amount of $135.1 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 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 $68.6 million and $111.7 million at September 30, 2018 and December 31, 2017, respectively. Of these amounts, cash held by our non-U.S. operations totaled $63.7 million and $75.7 million as of September 30, 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 September 30, 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.

Cash Flow Summary

Cash flows from operating, investing, and financing activities as reflected in our Consolidated Statements of Cash Flows are summarized in the following table:

	Nine Months Ended September 30,
(in millions)	2018			2017
Net cash flows provided by (used in):
Operating activities	$	39.3		$	31.1
Investing activities	(66.0		)	(45.4		)
Financing activities	(16.3		)	5.0
Effect of exchange rate changes on cash and cash equivalents	(0.1		)	0.8
Net decrease in cash and cash equivalents	$	(43.1	)	$	(8.5	)

Operating Activities

Cash provided by operating activities in 2018 increased $8.2 million compared to 2017, primarily due to a lower investment in inventory.

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, partially offset with escrow proceeds from the sale of the Timing Device Business in the prior year. 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 9.0% to 10.0% of revenue.

Financing Activities

Cash used in financing activities during 2018 is primarily related to the $10.0 million payment on our revolving credit facility and the $4.5 million payment of taxes related to net share settlement of equity awards. The cash provided by financing activities for 2017 was primarily related to the borrowings under our revolving credit facility of $15.0 million and the $3.3 million of proceeds received for option exercises, partially offset by the $7.2 million principal payment on our term loan and the $4.9 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 15. Commitments and Contingent Liabilities to our Consolidated Financial Statements.

Borrowings

Borrowings (net of debt issuance costs, debt discount, and amortization) consist of the following:

(in millions)	September 30, 2018		December 31, 2017
3.25% convertible senior notes	$	147.2	$	141.9
Revolving credit facility	40.7		50.7
Total	187.9		192.6
Less current maturities (1)	—		—
Total long-term debt	$	187.9	$	192.6

⁽¹⁾ There are no required principal payments due under the 3.25% Convertible Senior Notes or the revolving credit facility until maturities in November 2021 and October 2022, respectively.

45

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%. At September 30, 2018, 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 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 17. 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 nine months ended September 30, 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 third 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.

Item 1. Legal Proceedings

Item 1A. Risk Factors

For a discussion of our potential risks and uncertainties, see the information under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2017. There are no material developments in our previously reported risk factors, except for the following:

Our effective tax rate may fluctuate which will impact our future financial results.

Our effective tax rate may be adversely impacted by, among other things, changes in the mix of our earnings among countries having differing statutory tax rates, changes in the valuation of deferred tax assets, or changes in tax laws where we operate, including the resulting tax effects of the Tax Cuts and Jobs Act (“Tax Reform Act”). We cannot give any assurance as to the stability or predictability of our effective tax rate in the future because of, among other things, uncertainty regarding the tax laws and policies of the countries where we operate.

The estimated effects of applicable tax laws, including current interpretation of the Tax Reform Act and recently proposed regulations on the Section 965 deemed repatriation tax on U.S. persons with foreign earnings accumulated offshore, have been incorporated into our financial results. The U.S. Treasury Department, Internal Revenue Service, and other standard-setting bodies could interpret or issue future legislation or guidance which impact how provisions of the Tax Reform Act will be applied or otherwise administered that is different from our interpretation, which could have a material adverse impact on our effective tax rate as well as our future financial results and tax payments.

Further, our tax returns are subject to periodic reviews or audits by domestic and international authorities, and these audits may result in adjustments to our provision for taxes or allocations of income or deductions that result in tax assessments different from amounts that we have estimated. We regularly assess the likelihood of an adverse outcome resulting from these audits to determine the adequacy of our provision for taxes. There can be no assurance as to the outcome of these audits or that our tax provisions will not change materially or be adequate to satisfy any associated tax liability. If our effective tax rates were to increase or if our tax liabilities exceed our estimates and provisions for such taxes, our financial results could be adversely affected.

Our effective tax rate is favorably impacted by tax holidays granted to us by certain foreign jurisdictions, which lowers the tax rates we are subject to for a period of time as compared to the countries' statutory tax rates. These tax holidays are subject to the satisfaction of certain conditions, including exceeding certain annual thresholds of operating expenses and gross sales. If we fail to satisfy such conditions, our effective tax rate may be significantly adversely impacted. For additional detail, see Note 12. Income Taxes to our Consolidated Financial Statements under Item 8, "Financial Statements and Supplementary Data." Moreover, tax rates and laws in the countries where we operate may change, or tax reforms may be enacted domestically or in foreign jurisdictions which adversely affect our liquidity, cash flows, and future reported financial results or our ability to continue to structure and conduct our business as is done currently.

New tariffs could adversely impact our business, results of operations, and financial position.

Changes in trade policy in the United States and other countries, including changes in trade agreements and the imposition of tariffs and the resulting consequences, may have adverse impacts on our business, results of operations, and financial condition. The U.S. government has indicated and demonstrated its intent to alter its approach to international trade policy through the renegotiation, and potential termination, of certain existing bilateral or multi-lateral trade agreements and treaties with, and the imposition of tariffs on a wide range of products and other goods from, China, countries in Europe, the Middle East, Africa, and other countries. As noted previously, we have invested significantly in our manufacturing facilities in China and Southeast Asia. Given our manufacturing in those countries, and our limited manufacturing elsewhere, trade policy changes in the United States or other countries, such as the tariffs already proposed, implemented, and threatened in 2018, present particular risks for us. Tariffs already announced and implemented are having an adverse effect on a small percentage of our capacitor products, tariffs announced but not yet implemented could have an adverse effect on our other products, and threatened tariffs could adversely affect all of our products. There are also risks associated with retaliatory tariffs and resulting trade wars. We cannot predict future trade policy, the terms of any renegotiated trade agreements or treaties, or tariffs and their impact on our business. A trade war could have a significant adverse effect on world trade and the world economy. To the extent that trade tariffs and other restrictions imposed by the United States or other countries increase the price of, affect our ability to supply or customer demand for, our products or components or materials used in our products, in the United States or other countries, or create adverse tax consequences, our costs or gross margins of our products may be adversely affected and the demand from our customers for our products may be impacted. If we deem it necessary to alter all or a portion of our activities or operations in response to such policies, agreements, or tariffs, our capital and operating costs may increase. As a result, changes in international trade policy, changes in trade agreements, and tariffs could adversely affect our business, results of operations, and financial condition.

Discontinued Operations [Abstract]

Disposal Groups, Including Discontinued Operations, Disclosure

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 its 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 $135.1 million. The Company recorded a gain of $63.9 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 included $10.0 million held in escrow that was received during the third quarter of 2018 and was previously 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 Speaker and Receiver Product Line had no effect on the Company's results of operations for the three and nine months ended September 30, 2018.

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:

Acquisitions [Abstract]

Business Combination Disclosure [Text Block]

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 accrued expenses 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 $9.5 million and $2.6 million, respectively, from the date of acquisition through September 30, 2018.

The table below represents the final 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	2.0
Customer relationships	7.3
Unpatented technologies	2.0
Trademarks and other amortized intangible assets	0.4
Other assets	0.2
Goodwill	3.0
Assumed current liabilities	(0.2		)
Total purchase price	$	18.7

The Company recorded a purchase price adjustment related to property, plant, and equipment during the nine months ended September 30, 2018, resulting in an increase to goodwill of $0.1 million. The adjustment did not impact the Consolidated Statements of Earnings.

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.

The unaudited pro-forma financial information does not necessarily represent the results that would have occurred had the acquisition occurred on January 1, 2017. In addition, the unaudited pro-forma information should not be deemed to be indicative of future results.

Impairments [Abstract]

Asset Impairment Charges [Text Block]

4. Impairments The Company evaluates long-lived assets for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. During the second quarter of 2017, an updated strategic plan was completed for Audio segment product lines. The updated strategic plan identified a decline of future demand for a specific product line, which indicated projected future cash flows may not be sufficient to recover the carrying value of the associated unpatented technologies and property, plant, and equipment assets. The utilization of undiscounted future cash flows was used to determine recoverability of the long-lived assets. The fair value of the intangibles was determined through the use of discounted cash flows, and the fair value of fixed assets was determined using their liquidation value. As a result of this analysis, the Company concluded that the fair values of these long-lived assets were less than their respective carrying values as of June 30, 2017. The Company recorded total impairment charges of $21.3 million, of which $5.1 million was related to fixed assets and $16.2 million was related to intangible assets. The Company recorded $1.4 million of the charges within Impairment charges in Gross profit and recorded $19.9 million within the Impairment charges line item in Operating expenses within the Consolidated Statements of Earnings.

Hedging Transaction and Derivative Instruments (Notes)

9 Months Ended

Sep. 30, 2018

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Hedging Transaction 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.

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 September 30, 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 $51.0 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. The Company designated the swap as a cash flow hedge with re-measurement gains and losses recorded through AOCI. 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 interest rate swap ended in July 2018.

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 expense (income), 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 September 30, 2018 and December 31, 2017, the notional value of the derivatives related to economic hedging was $9.0 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 expense (income), 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 17. Recent Accounting Standards for additional information on the adoption of this standard.

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 September 30, 2018, 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. 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)	September 30, 2018			December 31, 2017
Liability component:
Principal	$	172.5		$	172.5
Less debt issuance costs and debt discount, net of amortization	(25.3		)	(30.6		)
Total	147.2			141.9
Less current maturities (1)	—			—
Long-term portion	$	147.2		$	141.9
Equity component (2)	$	29.9		$	29.9

⁽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 September 30, 2018 was $197.3 million. The fair value was determined based on the closing trading price of the Notes as of the last trading day for the third quarter of 2018.

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

	Three Months Ended September 30,				Nine Months Ended September 30,

Amortization of debt discount	1.6		1.4		4.7		4.3
Total	$	3.2	$	3.1	$	9.5	$	9.2

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

Revolving credit facility borrowings consist of the following:

(in millions)	September 30, 2018		December 31, 2017
$400.0 million revolving credit facility due October 2022	$	40.7	$	50.7
Less current maturities (1)	—		—
Long-term portion	$	40.7	$	50.7

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

On October 11, 2017, the Company 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 September 30, 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 3.48% and 3.68% for the nine months ended September 30, 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 nine months ended September 30, 2018 and 2017 includes interest expense related to the monthly interest rate swap settlements that ended in July 2018. The weighted-average commitment fee on the revolving line of credit was 0.24% and 0.37% for the nine months ended September 30, 2018 and 2017, respectively.

Income Taxes (Notes)

Income Tax Disclosure [Abstract]

Income Taxes

12. 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 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 has been able to reasonably estimate certain tax effects, and has 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. On August 1, 2018, the Internal Revenue Service (“IRS”) released comprehensive proposed regulations on the Section 965 deemed repatriation tax imposed on U.S. persons with foreign earnings accumulated offshore (the "Proposed 965 Regulations"). As a result, the Company has recorded adjustments of $3.1 million and $3.3 million to its provisional amounts during the three and nine months ended September 30, 2018, respectively. The Company continues to gather information to complete its accounting for these provisional items and intends to complete its accounting within the Staff Accounting Bulletin No. 118 (“SAB 118”) measurement period, which is no later than the fourth quarter of 2018.

During the three and nine months ended September 30, 2018, the Company recorded an increase to its uncertain tax positions of $36.0 million due to the resulting consequences of the Tax Reform Act. The Company believes it is reasonably possible that some or all of the uncertain tax position, recorded as a result of consequences of the Tax Reform Act, may be reversed within the next twelve months.

The year-to-date ETR deviates from the statutory U.S. federal income tax rate, primarily due to the Tax Reform Act and its resulting consequences that were accounted for as uncertain tax positions, the taxing jurisdictions where 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 and nine months ended September 30, 2018 was a 170.4% provision and a 143.8% provision, respectively. During the three and nine months ended September 30, 2018, the ETR from continuing operations was impacted by discrete items totaling $39.7 million and $39.9 million of expense, respectively, primarily related to an increase in its uncertain tax positions of $36.0 million due to resulting consequences of the Tax Reform Act and a $3.1 million adjustment to the Company's SAB 118 provisional deemed repatriation tax. Absent the discrete items, the ETR from continuing operations for the three and nine months ended September 30, 2018 was a 13.4% provision and a 17.1% provision, respectively.

The Company's ETR from continuing operations for the three and nine months ended September 30, 2017 was a 29.5% provision and a 71.6% provision, respectively. During the three and nine months ended September 30, 2017, the ETR from continuing operations was impacted by discrete items totaling $0.7 million and $2.8 million of expense, respectively. The Company settled its 2013 pre-spin-off U.S. federal income tax examination during the period and recognized $2.9 million of expense. Additionally, the Company recorded a $0.2 million tax benefit resulting from a reduction to its uncertain tax position reserves. Absent the discrete items, the ETR from continuing operations for the three and nine months ended September 30, 2017 was a 24.8% provision and a 52.7% provision, 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 and nine months ended September 30, 2018 was approximately $7.2 million and $11.3 million, respectively, or $0.08 and $0.13 on a per share basis. The continuing operations benefit of these incentives for the three and nine months ended September 30, 2017 was approximately $7.8 million and $11.7 million, respectively, or $0.09 and $0.13 on a per share basis.

There was no unrecognized compensation expense related to SSARs at September 30, 2018. At September 30, 2018, unrecognized compensation expense related to stock options not yet exercisable of $7.1 million is expected to be recognized over a weighted-average period of 1.3 years.

RSUs

The following table summarizes the Company's restricted stock unit ("RSU") balances for the nine months ended September 30, 2018:

	Share units		Weighted-average grant date fair value
Unvested at December 31, 2017	2,202,576		$	16.54

Forfeited	(356,906	)	14.73
Unvested at September 30, 2018	2,487,982		$	15.15

At September 30, 2018, $27.3 million of unrecognized compensation expense related to RSUs is expected to be recognized over a weighted-average period of 1.4 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, 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.

The following table summarizes the Company's PSU balances for the nine months ended September 30, 2018:

	Share units	Weighted-average grant date fair value
Unvested at December 31, 2017	176,000	$	15.32

Commitments and Contingencies Disclosure [Abstract]

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 September 30, 2018 and December 31, 2017.

Recent Accounting Standards

Recently Issued Accounting Standards

In August 2018, the FASB issued ASU 2018-14 to amend disclosure requirements related to defined benefit pension and other postretirement plans. The standard is effective for public business entities for fiscal years beginning after December 15, 2020. Early adoption is permitted and retrospective application of the guidance is required. The Company has not yet determined the impact of the standard on its disclosures or its adoption date.

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 and issued subsequent amendments to the initial guidance within ASU 2018-01, ASU 2018-10, and ASU 2018-11, which are collectively referred to as "ASC 842." This guidance requires a lessee to recognize a lease liability and right-of-use asset for all leases, including operating leases, with a term greater than 12 months. The guidance 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. Prior to the issuance of ASU 2018-11 in July 2018, the standard required a modified retrospective transition method under which the guidance would be applied at the beginning of the earliest comparative period presented in the financial statements. ASU 2018-11 allows entities to elect an additional transition method under which the guidance would be applied as of the adoption date. The Company plans to adopt the standard under this new transition method that will not require the restatement of comparative period financial statements.

The standard includes a number of optional practical expedients that entities may elect to apply. The Company plans to elect the transition package of practical expedients for leases that commenced before the adoption date, which among other things, allows the Company to carry forward historical lease classifications. The Company also plans to elect the practical expedient to not separate nonlease components from lease components, which may increase lease liabilities and right-of-use assets through the inclusion of payments for nonlease components such as maintenance. The Company continues to evaluate other practical expedients and accounting policy elections.

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 impact of adoption will depend on the lease portfolio as of the transition date and the Company's accounting policy elections. The Company expects adoption of the standard will have a material impact on the Consolidated Balance Sheets related to the recognition of lease liabilities and right-of-use assets for operating leases. The Company has not yet determined the other impacts 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. 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 9. 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 and nine months ended September 30, 2018, net benefit income other than service cost of $0.3 million and net benefit cost other than service cost of $0.6 million was recognized within the Other expense (income), net line on the Consolidated Statements of Earnings. For the three months ended September 30, 2017, net benefit income other than service cost of $0.1 million previously presented in the Cost of goods sold line on the Consolidated Statements of Earnings has been reclassified to the Other expense (income), net line. For the nine months ended September 30, 2017, net benefit income other than service cost of $0.1 million previously presented in both the Selling and administrative expenses and Cost of goods sold lines 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.

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 September 30, 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 $132.5 million and $127.0 million as of September 30, 2018 and January 1, 2018, respectively. See Note 16. Segment Information for disclosures regarding the disaggregation of revenues.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Accounting Policy

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.

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.
