Notes to Condensed Consolidated Financial Statements

(Unaudited)

Note 1. Basis of Financial Statement Presentation

The condensed consolidated financial statements contained herein are unaudited and have been prepared from the books and records of KEMET Corporation and its subsidiaries (“KEMET” or the “Company”). In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods. The condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q, and therefore, do not include all information and footnotes necessary for a complete presentation of financial position, results of operations, and cash flows in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). Although the Company believes the disclosures are adequate to make the information presented not misleading, it is suggested that these condensed consolidated financial statements be read in conjunction with the audited financial statements and notes thereto included in the Company’s Form 10-K for the fiscal year ended March 31, 2017 (the “Company’s 2017 Annual Report”).

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. In consolidation, all significant intercompany amounts and transactions have been eliminated.  Certain prior year amounts have been reclassified to conform to current year presentation.  Net sales and operating results for the quarter and six-month periods endedSeptember 30, 2017 are not necessarily indicative of the results to be expected for the full year.

The Company’s significant accounting policies are presented in the Company’s 2017 Annual Report.

Use of Estimates and Assumptions

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, assumptions, and judgments based on historical data and other assumptions that management believes are reasonable.  These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. In addition, they affect the reported amounts of revenues and expenses during the reporting period.

The Company’s judgments are based on management’s assessment as to the effect certain estimates, assumptions, or future trends or events may have on the financial condition and results of operations reported in the unaudited condensed consolidated financial statements. It is important that readers of these unaudited financial statements understand that actual results could differ from these estimates, assumptions, and judgments.

Recently Issued Accounting Pronouncements

New Accounting Standards Adopted/Issued

In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-12, Targeted Improvements to Accounting for Hedging Activities. The update amends and simplifies existing guidance in order to allow companies to more accurately present the economic effects of risk management activities in the financial statements. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this guidance on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The update requires employers to 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 income statement separately from the service cost component and outside a subtotal of Operating income. The Company states the other components of net benefit cost within Other (income) expense, net, on its Condensed Consolidated Statements of Operations. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The update requires retrospective application to all periods presented. The Company adopted this guidance in the first quarter of fiscal year 2018; the adoption of this guidance had an immaterial impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other. The update eliminates the requirement to calculate the implied fair value of goodwill to measure the amount of impairment loss, if any, under the second step of the current goodwill impairment test. Under the update, the goodwill impairment loss would be measured as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The effective

7

date of this update is for annual reporting periods beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this guidance on the Company’s consolidated financial statements, however the adoption of this guidance is not expected to have a significant effect on the Company’s consolidated financial position, results of operations, or cash flows.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory. The update requires entities to recognize the income tax consequences of many intercompany asset transfers at the transaction date. The seller and buyer will immediately recognize the current and deferred income tax consequences of an intercompany transfer of an asset other than inventory.  The tax consequences were previously deferred. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The update requires modified retrospective transition method which is a cumulative effect adjustment to retained earnings as of the beginning of the first effective reporting period. The Company adopted this guidance as of April 1, 2017 and recorded a cumulative effect adjustment to retained earnings of $203,000.

In August 2016, the FASB issued ASU No. 2016-15,Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update clarifies how cash receipts and cash payments in certain transactions are presented and classified in the statement of cash flows. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The update requires retrospective application to all periods presented but may be applied prospectively if retrospective application is impracticable. The Company is currently evaluating the impact of the adoption of this guidance on the Company’s consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases. The ASU requires lessees to recognize a right-of-use asset and a lease liability for virtually all of their leases (other than short-term leases). The guidance is to be applied using a modified retrospective approach at the beginning of the earliest comparative period in the financial statements. This ASU is effective for fiscal years and interim periods within those years beginning after December 15, 2018. Early application is permitted. The Company is currently in the process of assessing the impact the adoption of this guidance will have on the Company’s consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which supersedes existing accounting standards for revenue recognition and creates a single framework. The new guidance requires either a retrospective or a modified retrospective approach at adoption. Additional updates to Topic 606 issued by the FASB in 2015 and 2016 include the following:

• ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which defers the effective date of the new guidance such that the new provisions will now be required for fiscal years, and interim periods within those years, beginning after December 15, 2017 (ASU No. 2015-14 is effective for the Company’s fiscal year that begins on April 1, 2018 and interim periods within that fiscal year).

• ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations, which clarifies the implementation guidance on principal versus agent considerations (reporting revenue gross versus net).

• ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarifies the implementation guidance on identifying performance obligations and classifying licensing arrangements.

• ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which clarifies the implementation guidance in a number of other areas.

• ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers.

The effective date of this guidance is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted, but not before the Company’s fiscal year that began on April 1, 2017 (the original effective date of the ASU). The Company plans to adopt the requirements of the new standard in the first quarter of fiscal year 2019.

The Company has completed the assessment phase, applied the principles of the new standard using the five step method to material customer contracts, and held discussions with key stakeholders and management. The Company is currently finalizing changes to accounting policies and internal controls over financial reporting. Key changes in the ASU that could potentially impact the Company’s revenue recognition include certain customer tooling contracts primarily within the original equipment manufacturers (“OEM”) channel and the deferral of incremental costs to fulfill a contract. The Company is currently

8

finalizing the impact of the ASU on the consolidated results of operations, financial position, cash flows and financial statement disclosures.

There are currently no other accounting standards that have been issued that will have a significant impact on the Company’s financial position, results of operations or cash flows upon adoption.

Fair Value Measurement

The Company utilizes three levels of inputs to measure the fair value of (a) nonfinancial assets and liabilities that are recognized or disclosed at fair value in the Company’s consolidated financial statements on a recurring basis (at least annually) and (b) all financial assets and liabilities. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.

The first two inputs are considered observable and the last is considered unobservable. The levels of inputs are as follows:

• Level 1—Quoted prices in active markets for identical assets or liabilities.

• Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices 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 the assets or liabilities.

• Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Assets and liabilities measured at fair value on a recurring basis as of September 30, 2017 and March 31, 2017 are as follows (amounts in thousands):

	Carrying Value September 30,			Fair Value September 30,			Fair Value Measurement Using								Carrying Value March 31,			Fair Value March 31,			Fair Value Measurement Using

⁽²⁾ The valuation approach used to calculate fair value was a discounted cash flow based on the borrowing rate for each respective debt facility.

⁽³⁾ See Note 8, “Investment in TOKIN”, for a description of the TOKIN option, which was canceled on April 19, 2017 pursuant to the terms of the TOKIN Purchase Agreement.  The value of the option depended on the enterprise value of TOKIN and its forecasted EBITDA over the duration of the option. The option was valued using option pricing methods in a Monte Carlo simulation.

Warrant

On September 11, 2017, K Equity sold the remaining portion of the Platinum Warrant to UBS Securities LLC (the “Underwriter”), in connection with the offering of 8,416,814 shares of the Company’s common stock, at a public offering price of $21.57 per share. The Company filed a registration statement on Form S-3 to register the offer and resale by K Equity of the shares. The Company did not receive any of the proceeds from the sale of the shares in the Offering, but received approximately $8.8 million from the Underwriter in connection with the cash exercise of the Platinum Warrant for all 8,416,814 shares underlying the Platinum Warrant at an exercise price of $1.05 per share.

As of September 30, 2017, K Equity does not have any outstanding warrants for shares of the Company’s common stock.

Revenue Recognition

The Company ships products to customers based upon firm orders and revenue is recognized when the sales process is complete. This occurs when products are shipped to the customer in accordance with the terms of an agreement of sale, there is a fixed or determinable selling price, title and risk of loss have been transferred and collectability is reasonably assured. Based on product availability, customer requirements and customer consent, the Company may ship products earlier than the initial planned ship date. Shipping and handling costs are included in cost of sales.

A portion of sales is related to products designed to meet customer specific requirements. These products typically have stricter tolerances making them useful to the specific customer requesting the product and to customers with similar or less stringent requirements. The Company recognizes revenue when title to the products transfers to the customer.

A portion of sales is made to distributors under agreements allowing certain rights of return and price protection on unsold merchandise held by distributors. The Company’s distributor policy includes inventory price protection and “ship-from-stock and debit” (“SFSD”) programs common in the industry.

KEMET’s SFSD program provides authorized distributors with the flexibility to meet marketplace prices by allowing them, upon a pre-approved case-by-case basis, to adjust their purchased inventory cost to correspond with current market demand. Requests for SFSD adjustments are considered on an individual basis, require a pre-approved cost adjustment quote from their local KEMET sales representative and apply only to a specific customer, part, specified special price amount, specified quantity, and are only valid for a specific period of time. To estimate potential SFSD adjustments corresponding with current period sales, KEMET records a sales reserve based on historical SFSD credits, distributor inventory levels, and certain accounting assumptions, all of which are reviewed quarterly.

Most of the Company’s distributors have the right to return to KEMET a certain portion of the purchased inventory, which, in general, does not exceed 6% of their purchases from the previous fiscal quarter. KEMET estimates future returns based on historical return patterns and records a corresponding allowance on the Condensed Consolidated Balance Sheets. The Company also offers volume based rebates on a case-by-case basis to certain customers in each of the Company’s sales channels.

The establishment of sales allowances is recognized as a component of the line item “Net sales” on the Condensed Consolidated Statements of Operations, while the associated reserves are included in the line item “Accounts receivable, net” on the Condensed Consolidated Balance Sheets. Estimates used in determining sales allowances are subject to various factors. This includes, but is not limited to, changes in economic conditions, pricing changes, product demand, inventory levels in the supply chain, the effects of technological change, and other variables that might result in changes to the Company’s estimates.

10

The Company provides a limited warranty to customers that the Company’s products meet certain specifications. The warranty period is generally limited to one year, and the Company’s liability under the warranty is generally limited to a replacement of the product or refund of the purchase price of the product. Warranty costs as a percentage of net sales were less than 1.0% for the quarters and six-month periods endedSeptember 30, 2017 and 2016. The Company recognizes warranty costs when they are both probable and reasonably estimable.

Note 2. Acquisitions

Sale of Electromagnetic Business and Acquisition of Remaining Interest in TOKIN

Between February 1, 2013 and April 19, 2017, KEMET, through its wholly-owned subsidiary, KEMET Electronics Corporation (“KEC”), held a 34% economic interest in TOKIN Corporation (“TOKIN”) pursuant to a Stock Purchase Agreement (the “Stock Purchase Agreement”) by and among KEC, TOKIN and NEC Corporation (“NEC”), as calculated based on the number of common shares held by KEC, directly and indirectly, in proportion to the aggregate number of common and preferred shares of TOKIN outstanding as of such date. TOKIN was established in Japan in 1938 and is engaged in production and distribution of tantalum capacitors, transmitting communication devices, magnetic devices, piezoelectric devices and sensors. TOKIN has six manufacturing locations throughout Asia and was previously operating as a joint venture with NEC.

On April 14, 2017, TOKIN closed on the sale of its electro-mechanical devices (“EMD”) business to NTJ Holdings 1 Ltd. (“NTJ”), a special purpose entity that is owned by funds managed or operated by Japan Industrial Partners, Inc. (“JIP”), pursuant to a master sale and purchase agreement (the “EMD Master Sale and Purchase Agreement”) previously entered into between TOKIN, NTJ and JIP (“Sale of EMD”). The initial selling price for EMD was JPY 48.2 billion, or approximately $431.0 million, using the March 31, 2017 exchange rate of 111.823 Japanese Yen to 1.00 U.S. Dollar, and is subject to certain working capital adjustments pursuant to the EMD Master Sale and Purchase Agreement. At the closing of the Sale of EMD, TOKIN used a portion of the sale proceeds to repay debt related to a shareholder loan from NEC. The TOKIN historical balance sheet was adjusted to reflect the removal of net assets sold and other items directly impacted by the Sale of EMD. Additionally, due to KEMET’s 34% equity interest in TOKIN held as of the closing, adjustments have been made to reflect KEMET’s accounting for the Sale of EMD in accordance with the equity method of accounting.

On April 19, 2017, pursuant to a stock purchase agreement (the “TOKIN Purchase Agreement”) dated February 23, 2017 between KEC and NEC, KEC completed its acquisition, subject to final purchase price adjustment, of the remaining 66% economic interest in TOKIN, and as a result, TOKIN is now a 100% owned indirect subsidiary of KEMET (the “TOKIN Acquisition”). Under the terms of the TOKIN Purchase Agreement, KEC paid NEC JPY 16.2 billion, or approximately $148.6 million (using the April 19, 2017 exchange rate of 109.007 Japanese Yen to 1.00 U.S. Dollar), for all of the outstanding shares of TOKIN it did not already own. The preliminary purchase price was comprised of JPY 6.0 billion, or approximately $55.0 million (using the April 19, 2017 exchange rate of 109.007 Japanese Yen to 1.00 U.S. Dollar) plus JPY 10.2 billion, or approximately $93.6 million, which represented one-half of the estimated excess net cash proceeds (“Excess Cash”) from the sale of TOKIN’s EMD business. The acquisition price was subject to working capital adjustments pursuant to the EMD Master Sale and Purchase Agreement, as a result the acquisition price was increased by JPY 0.3 billion, or approximately $3.0 million (using the September 30, 2017 exchange rate of 112.502 Japanese Yen to 1.00 U.S. Dollar) in the second quarter of fiscal year 2018.

The Company believes the acquisition of TOKIN will expand KEMET’s geographic presence, combining KEMET’s presence in the western hemisphere and TOKIN’s excellent position in Asia to enhance customer reach and create an entrance into Japan for KEMET. The Company believes TOKIN’s product portfolio is a strong complement to KEMET’s existing product portfolio. KEMET believes the combination creates a leader in the combined polymer and tantalum capacitors market. The acquisition also enhances KEMET’s product diversification with entry into Electro-Magnetic Compatible components ("EMC") as well as sensors and actuators. With the increased scale, the Company anticipates optimizing costs through competitive raw materials sourcing and maximizing operating efficiencies. Consistent with expectations, the acquisition has been accretive to earnings with improvement in Net income, Adjusted EBITDA and cash flow. TOKIN’s tantalum capacitor business is included within KEMET’s Solid Capacitors reportable segment and the remainder of TOKIN’s business formed a new reportable segment for KEMET, Electro-magnetic, Sensors & Actuators (“MSA”).

The following table shows the preliminary components of the acquisition price; the excess cash value may change upon finalization of working capital adjustments for the Sale of EMD (amounts in thousands):

Upfront cash consideration (1)	$	148,614
Acquisition payable (2)	3,144
Indemnity asset  (3)	8,500
Less: Put option (4)	(9,900		)
Net consideration transferred	$	150,358

_________________

⁽¹⁾ The upfront cash payment is comprised of JPY 6.0 billion plus one half of Excess Cash in an amount of approximately JPY 10.2 billion, approximately $55.0 million and $93.6 million, respectively.

⁽²⁾ Current estimate of the additional amount due to NEC Corporation upon the settlement of the adjusted purchase price for the EMD sale.

⁽³⁾ Pursuant to the Stock Purchase Agreement between KEMET and NEC, NEC was required to indemnify TOKIN and/or KEC for any breaches by TOKIN or NEC of certain representations, warranties and covenants in the Stock Purchase Agreement. NEC’s aggregate liability for indemnification claims was limited to $25.0 million. Prior to the acquisition, KEMET's equity method investment balance included an $8.5 million indemnification asset pursuant to this indemnification arrangement. In connection with the TOKIN Acquisition, NEC was released from its indemnification obligations to KEMET without an exchange of consideration; as such, this amount of released obligation is included as purchase consideration by KEMET.

⁽⁴⁾ Pursuant to the option agreement, dated as of March 12, 2012, by and among NEC and KEMET (the “Option Agreement”), from April 1, 2015 through May 31, 2018, NEC had the right to require KEC to purchase all outstanding capital stock of TOKIN (the “Put Option”). The fair value of the Put Option of $9.9 million was reflected as a liability on KEMET’s balance sheet prior to KEMET’s acquisition of the remaining 66% economic interest in TOKIN. The Put Option was canceled, pursuant to the terms of the TOKIN Purchase Agreement with no exchange of consideration between NEC and KEMET. Accordingly, the fair value of the Put Option reduces the amount of consideration paid to acquire NEC’s equity in TOKIN.

In accordance with ASC 805, KEMET’s previously held 34% equity interest in TOKIN and the assets acquired and the liabilities assumed have been measured at their fair values based on various preliminary estimates. The preliminary acquisition-date fair value of KEMET’s previously held 34% equity interest in TOKIN is approximately $207.8 million.

The following table presents the preliminary allocations of the aggregate purchase price based on the estimated fair values of the assets and liabilities (amounts in thousands):

	Fair Value
Cash	$	315,743
Accounts Receivable	79,295
Inventory	35,310
Other current assets	20,899
Property, Plant and equipment	159,597
Intangible assets (1)	35,452
Equity method investments	12,795
Other assets	8,533
Current portion of long term debt	(3,225		)
Accounts payable	(81,642		)
Accrued expenses	(46,276		)
Other non-current obligations	(103,486		)
Deferred income taxes (2)	(10,372		)
Total net assets acquired	$	422,623

_________________

⁽¹⁾ Includes trade name for $8.1 million and products and relationships of $25.2 million. TOKIN’s technology, products, and relationships were valued as a grouped, composite intangible asset due to the Company’s products being dependent on the existing technology, which enabled a product portfolio that customers found appealing in selecting and designing electronic components for purchase. The trade names were valued based on the relief from royalty method and and have indefinite remaining useful lives. The products and relationships were valued on the excess earnings method and are amortized over 10 years.

⁽²⁾ Amount revised in the second quarter of fiscal year 2018; however, the deferred tax value is still preliminary.

There were $0.6 million of acquisition-related costs, which were all recognized as an expense in the line item “Selling, general and administrative expenses” on the Condensed Consolidated Statements of Operations.

12

The above allocation of purchase price has been prepared based on preliminary estimates; the final amounts recorded may differ materially from the information presented herein. These estimates are subject to change pending further review of the acquired business. The following components of the initial valuation are still preliminary: deferred income taxes, accounts receivable reserves, inventory obsolescence, equity method investments, products and relationships, property plant and equipment for some locations, and management continues to reassess the bargain gain in accordance with ASC 805. In the quarter ended September 30, 2017, the acquisition payable was reduced to $3.1 million due to an update to the Excess Cash calculation and the value of the deferred income tax liability was increased $0.7 million due to additional detail received from the foreign subsidiaries, which changed the categorization and breakouts of deferred tax assets and liabilities, along with their corresponding valuation allowances. A change in the fair value of assets acquired or liabilities assumed in the merger from those preliminary valuations presented above would result in a corresponding change in the amount of bargain purchase gain that resulted from the merger in a business combination when the fair value of net assets acquired exceeds the sum of consideration transferred and the fair value of the acquirer’s previously held interest in the acquiree. The gain is recognized immediately in earnings in accordance with U.S. GAAP.

The following table reflects the preliminary bargain purchase gain resulting from the TOKIN Acquisition (amounts in thousands):

Net consideration transferred	$	150,358
Preliminary fair value of KEMET’s previously held equity interest in TOKIN	207,823
Less: Preliminary fair value of net assets acquired	(422,623		)
Bargain purchase gain	$	(64,442	)

The gain is included in the line item “Acquisition gains” in the Condensed Consolidated Statements of Operations.

10.5% Senior Notes

On April 28, 2017, the Company repurchased and retired the full outstanding balance of $353.0 million of its 10.5% Senior Notes due May 1, 2018 (the “10.5% Senior Notes”). The Company had interest payable related to the 10.5% Senior Notes included in the line item “Accrued expenses” on its Condensed Consolidated balance sheets of zero and $15.4 million as of September 30, 2017 and March 31, 2017, respectively.

Term Loan Credit Agreement

On April 28, 2017, KEMET entered into a Term Loan Credit Agreement (the “Term Loan Credit Agreement”) by and among the Company, KEC (together with the Company, the “Borrowers”), Bank of America, N.A. as the Administrative Agent and Collateral Agent, Merrill Lynch, Pierce, Fenner & Smith Incorporated, as sole lead arranger and bookrunner and various other lenders thereto from time to time.

The Term Loan Credit Agreement provides for a $345 million term loan facility. In addition, the Borrowers may request incremental term loan commitments in an aggregate amount not to exceed $50 million (together with the initial $345 million term loan, the “Term Loans”). The proceeds were used, together with cash on hand, to fund the redemption of all of KEMET’s outstanding 10.5% Senior Notes, which were also called for redemption on April 28, 2017. The Term Loans were made with an original issue discount of 300 basis points. At the Company’s election, the Term Loans may be made as either Base Rate Term Loans or LIBO Rate Term Loans (each as defined in the Term Loan Credit Agreement). The applicable margin for term loans is 5.0% for Base Rate Term Loans and 6.0% for LIBO Rate Term Loans. All LIBO Rate Term Loans are subject to a pre-margin floor of 1.00%. The Term Loan Credit Agreement contains customary covenants and events of default.

14

The Company also entered into the Term Loan Security Agreement dated as of April 28, 2017 (the “Security Agreement”), by and among the Company, KEC and certain other subsidiaries of the Company and Bank of America, N.A., as collateral agent, pursuant to which the Company’s obligations under the Term Loan Credit Agreement are secured by a pledge of 65% of the outstanding voting stock of certain first-tier subsidiaries organized in Italy, Japan, Mexico and Singapore, and a second lien pledge on the collateral securing KEMET’s revolving credit facility. The obligations of the Company under the Term Loan Credit Agreement are guaranteed by certain of its subsidiaries, including KRC Trade Corporation, KEMET Services Corporation, KEMET Blue Powder Corporation and The Forest Electric Company. The Term Loans mature April 28, 2024, and may be extended in accordance with the Term Loan Credit Agreement. The Company may prepay loans under the Term Loan Credit Agreement at any time, subject to certain notice requirements and certain prepayment premiums during the first two years. The Company made an initial payment of 1.25% of the aggregate principal amount of the initial $345 million term loan, or $4.3 million, during the month of September. These payments will be made quarterly per the Term Loan Credit Agreement.

The Company currently pays interest on the Term Loan Security Agreement on a monthly basis due to favorable LIBO rates, and as such had no interest payable related to the Term Loan Security Agreement included in the line item “Accrued expenses” on its Condensed Consolidated balance sheets as of September 30, 2017 and March 31, 2017.

Revolving Line of Credit

In connection with the closing of the new Term Loan Credit Agreement, KEC also entered into Amendment No. 9 to Loan and Security Agreement, Waiver and Consent, dated as of April 28, 2017, by and among KEC, the other borrowers named therein, the financial institutions party thereto as lenders and Bank of America, N.A., as agent for the lenders (the “Loan Amendment”). The Loan Amendment increases the facility amount to $75.0 million and provides KEC with lower applicable interest rate margins and the ability to complete the refinancing. As part of the overall refinancing, KEC also repaid all amounts outstanding under the Loan Amendment.

As of September 30, 2017, there were no borrowings under the revolving line of credit, and the Company’s available borrowing capacity, which is based on factors including outstanding eligible accounts receivable, inventory and equipment collateral, under the Loan and Security Agreement was $71.7 million.

Other Debt

In January 2017, KEMET’s wholly-owned subsidiary, KEMET Electronics Portugal, S.A., received the first part of an interest free loan from the Portuguese Government in the amount of EUR 2.2 million (or $2.5 million) to be used for fixed asset purchases. In July 2017 KEMET Electronics Portugal, S.A. received the second part of the loan in the amount of EUR 277 thousand (or $325 thousand). The loan has a total term of eight years ending February 1, 2025. The loan will be repaid through semi-annual payments beginning on August 1, 2019. The first payment will be in the amount of EUR 185 thousand (or $211 thousand) beginning on August 1, 2019 and the remaining payments will be in the amount of EUR 210 thousand (or $248 thousand). Since the debt is non-interest bearing, we have recorded a debt discount in the amount of EUR 0.5 million (or $0.6 million) with an offsetting reduction to fixed assets. This discount will be amortized over the life of the loan through interest expense. If certain conditions are met, such as increased headcount, increased revenue and increased gross value added, a portion of the loan could be forgiven during fiscal year 2020.

In September 2017, TOKIN received a short term borrowing pursuant to an overdraft agreement with the 77 Bank of Miyagi, Japan, in the amount of 350 million yen (or $3.1 million), at an interest rate of 0.53% (JBA TIBOR + 40 basis points). The loan is due September 2018, and the loan agreement automatically renews if both parties choose not to terminate or modify it.

Note 5. Impairment Charges

The Company did not record any significant write downs and/or disposals of long-lived assets in the quarter ended September 30, 2017.

In the quarter ended September 30, 2016 KEMET recorded a write down of long-lived assets of $6.3 million due to the following two actions.

On August 31, 2016, KEC made the decision to shut-down operations of its wholly-owned subsidiary, KEMET Foil Manufacturing, LLC (“KFM”). Operations at KFM’s Knoxville, Tennessee plant ceased as of October 31, 2016. KFM supplied formed foil to the Company’s Film and Electrolytic segment (“Film and Electrolytic”), as well as to certain third party customers. The Company anticipates that Film and Electrolytic will achieve raw material cost savings by purchasing its formed foil from suppliers that have the advantage of lower utility costs. During the second fiscal quarter ending September 30, 2016, Film and Electrolytic recorded impairment charges totaling $4.1 million comprised of $3.0 million for the write down of property plant and equipment and $1.1 million for the write down of intangible assets. The impairment charges are recorded on the Condensed Consolidated Statements of Operations line item “Write down of long-lived assets”. In addition, the Company has accrued severance charges and restructuring costs described in Note 6, “Restructuring Charges.”

The Solid Capacitor segment (“Solid Capacitors”) initiated a plan to relocate its K-Salt operations from a leased facility to its existing Matamoros, Mexico facility. Impairment charges of approximately $2.1 million are recorded on the Condensed Consolidated Statements of Operations line item “Write down of long-lived assets”. In addition, the Company has accrued severance charges described in Note 6, “Restructuring Charges”.

Note 6. Restructuring Charges

KEMET’s restructuring plans are focused on making the Company more competitive by reducing excess capacity, relocating production to lower cost locations and eliminating unnecessary costs throughout the Company.

Note 8. Investment in TOKIN

Under the Option Agreement between KEC and NEC, from April 1, 2015 through May 31, 2018, NEC could have required KEC to purchase all outstanding capital stock of TOKIN from its stockholders, primarily NEC (the “Put Option”), provided that KEC’s payment of the Put Option price was permitted under the 10.5% Senior Notes and Loan and Security Agreement. On April 19, 2017, the Company acquired the remaining 66% economic interest in TOKIN and TOKIN became a 100% owned subsidiary of KEMET. See Note 2, “Acquisitions”, for additional information. Pursuant to the TOKIN Purchase Agreement, the Put Option was canceled. The line item “Other non-current obligations” on the Condensed Consolidated Balance Sheets included $9.9 million as of March 31, 2017 related to the fair value of the Put Option.

Note 9. Segment and Geographic Information

The Company is organized into three segments: Solid Capacitors, Film and Electrolytics and Electro-magnetic, Sensors & Actuators (“MSA”).  In prior periods we reported two reportable segments, Solid Capacitors and Film and Electrolytics. However, effective beginning the quarter ended June 30, 2017 and in connection with the TOKIN acquisition, TOKIN’s tantalum capacitor business is included within KEMET’s Solid Capacitors reportable segment and the remainder of TOKIN’s business became a new reportable segment (MSA). Refer to Note 2, "Acquisitions," for additional information on MSA.

The segments are responsible for their respective manufacturing sites as well as their respective research and development efforts. The Company does not allocate corporate indirect selling, general and administrative (“SG&A”) or shared Research and development (“R&D”) expenses to the segments.  Results for the first quarter of fiscal year 2018 have been reclassified to conform to the current period presentation where certain regional SG&A amounts have been allocated to certain segments, and also a portion of the allocation within the segments was allocated to costs of goods sold. These adjustments are reflected in the six-month results included below.

Solid Capacitors

Solid Capacitors operates in ten manufacturing sites in the United States, Mexico and Asia, and operates innovation centers in the United States and Japan. Solid Capacitors primarily produces tantalum, aluminum polymer, and ceramic capacitors which are sold globally.  Solid Capacitors also produces tantalum powder used in the production of tantalum capacitors.

Film and Electrolytic

Film and Electrolytic operates in nine manufacturing sites throughout Europe and Asia. Film and Electrolytic primarily produces film, paper, and electrolytic capacitors which are sold globally. In addition, this segment has product innovation centers in Portugal, Italy and Sweden.

MSA

MSA operates in four manufacturing sites throughout Asia. MSA primarily produces electro magnetically compatible materials and components, Piezo materials and actuators and various types of sensors which are sold globally. In addition, this segment has a product innovation center in Sendai, Japan.

Note 10.  Defined Benefit Pension and Other Postretirement Benefit Plans

The Company sponsors six defined benefit pension plans in Europe, one plan in Singapore, two plans in Mexico, and, with the completion of the TOKIN acquisition in April 2017, one plan in Japan.  In addition, the Company maintains two frozen post-retirement benefit plans in the United States: health care and life insurance benefits for certain retired United States employees who reached retirement age while working for the Company. The health care plan is contributory, with participants’ contributions adjusted annually. The life insurance plan is non-contributory. Finally, the Company sponsors one other post-retirement benefit plan in Japan.  Costs recognized for benefit plans are recorded using estimated amounts which may change as actual costs for the fiscal year are determined.

The components of net periodic benefit (income) costs relating to the Company’s pension and other postretirement benefit plans are as follows for the quarters ended September 30, 2017 and 2016 (amounts in thousands):

_________________

⁽¹⁾ In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. Please see Note 1, “Recently Issued Accounting Pronouncements," for additional information.

In fiscal year 2018, the Company expects to contribute up to $3.3 million to the pension plans, $0.5 million of which has been contributed as of September 30, 2017.  For the postretirement benefit plan, the Company’s policy is to pay benefits as costs are incurred. 

Note 11. Stock-Based Compensation

As of September 30, 2017, the KEMET Corporation Omnibus Incentive Plan (the “Incentive Plan”), which amended and restated the KEMET Corporation 2014 Amendment and Restatement of the KEMET Corporation 2011 Omnibus Equity Incentive Plan, approved by the Company’s stockholders on August 2, 2017, is the only plan the Company has to issue equity based awards to executives and key employees. Upon adoption of the Incentive Plan, no further awards were permitted to be granted under the Company’s prior plans, including the 1992 Key Employee Stock Option Plan, the 1995 Executive Stock Option Plan, and the 2004 Long-Term Equity Incentive Plan (collectively, the “Prior Plans”).

The Incentive Plan authorized the grant of up to 12.2 million shares of the Company’s Common Stock, comprised of 11.4 million shares under the Incentive Plan and 0.8 million shares remaining from the Prior Plans and authorizes the Company to provide equity-based compensation in the form of:

• stock options, including incentive stock options, entitling the optionee to favorable tax treatment under Section 422 of the Code;

• stock appreciation rights;

• restricted stock and restricted stock units (“RSUs”);

• other share-based awards; and,

• performance awards.

Except as described below, options issued under these plans vest within two to three years and expire ten years from the grant date. Restricted stock and RSUs issued under these plans vest over three to four years, except for RSUs granted to members of the Board of Directors, which vest within one year, and performance-based RSUs, which vest over a one-year period following achievement of two-year performance targets. The Company grants RSUs to members of the Board of Directors, the Chief Executive Officer and key management. Once vested and settled, RSUs are converted into restricted stock. For members of the Board of Directors and senior personnel, such restricted stock cannot be sold until 90 days after termination of service with the Company, or until the individual achieves the targeted ownership under the Company’s stock ownership guidelines, and only to the extent that such ownership level exceeds the target. Compensation expense is recognized over the respective vesting periods. 

Historically, the Board of Directors of the Company has approved annual Long Term Incentive Plans (“LTIP”) which cover two year periods and are primarily based upon the achievement of an Adjusted EBITDA range for the two-year period. At the time of the award, the individual plans entitle the participants to receive cash or RSUs, or a combination of both as

25

determined by the Company’s Board of Directors. The 2015/2016 LTIP, 2016/2017 LTIP, 2017/2018 LTIP, and 2018/2019 LTIP also awarded RSUs which vest over the course of three years from the anniversary of the establishment of the plan and are not subject to a performance metric. The Company assesses the likelihood of meeting the Adjusted EBITDA financial metric on a quarterly basis and adjusts compensation expense to match expectations. Any related liability is reflected in the line item “Accrued expenses” on the Condensed Consolidated Balance Sheets and any restricted stock unit commitment is reflected in the line item “Additional paid-in capital” on the Condensed Consolidated Balance Sheets.

On May 18, 2017, the Company granted RSUs under the 2018/2019 LTIP with a grant date fair value of $13.41 that vest as follows (amounts in thousands):

	Shares
May 18, 2018	65
May 18, 2019	65
May 18, 2020	67
Total shares granted	197

The following is the vesting schedule of RSUs under each respective LTIP, which vested during the six-month period endedSeptember 30, 2017 (shares in thousands):

	2017/2018	2016/2017	2015/2016
Time-based award vested	198	186	113
Performance-based award vested	—	173	102

Restricted stock activity, excluding the LTIP activity discussed above, for the six-month period endedSeptember 30, 2017 is as follows (amounts in thousands except fair value):

	Shares		Weighted- average Fair Value on Grant Date
Non-vested restricted stock at March 31, 2017	1,382		$	4.00

Vested	(153	)	5.03
Forfeited	(30	)	4.13
Non-vested restricted stock at September 30, 2017	1,542		$	7.23

The compensation expense associated with stock-based compensation for the quarters ended September 30, 2017 and 2016 is recorded on the Condensed Consolidated Statements of Operations as follows (amounts in thousands):

Note 14: Derivatives

In fiscal year 2015, the Company began using certain derivative instruments (i.e., foreign exchange contracts) to reduce exposure to the volatility of foreign currencies impacting revenues and the costs of its products.

Certain operating expenses at the Company’s Mexican facilities are paid in Mexican Pesos. In order to hedge a portion of these forecasted cash flows, the Company purchases foreign exchange contracts, with terms generally less than twelve months, to buy Mexican Pesos for periods and amounts consistent with underlying cash flow exposures. These contracts are designated as cash flow hedges at inception and monitored for effectiveness on a routine basis. There were $64.8 million and $49.1 million in Peso contracts (notional value) outstanding at September 30, 2017 and March 31, 2017, respectively.

The Company formally documents all relationships between hedging instruments and hedged items, as well as risk management objectives and strategies for undertaking various hedge transactions.

The Company records and presents the fair values of all of its derivative assets and liabilities in the Consolidated Balance Sheets on a net basis, since they are subject to master netting agreements. However, if the Company were to offset and record the asset and liability balances of its forward foreign currency exchange contracts on a gross basis, the amounts presented in the Consolidated Balance Sheets would be adjusted from the current net presentation to the gross amounts as detailed in the following table.

The balance sheet classifications and fair value of derivative instruments as of September 30, 2017 and March 31, 2017 are as follows (amounts in thousands):

	Fair Value of Derivative Instruments (1)
	September 30, 2017						March 31, 2017
Balance Sheet Presentation	As Presented (1)		Offset		Gross		As Presented (1)		Offset			Gross
Prepaid and other current assets	$	1,430	$	—	$	1,430	$	2,907	$	40		$	2,947

The impact on the Consolidated Statement of Operations for the quarters and six-month periods endedSeptember 30, 2017 and 2016 are as follows (amounts in thousands):

Statement Caption	Quarter Ended September 30, 2017		Quarter Ended September 30, 2016			Six-Month Period Ended September 30, 2017		Six-Month Period Ended September 30, 2016

Unrealized gains and losses associated with the change in value of these financial instruments are recorded in AOCI. Changes in the derivatives’ fair values are deferred and recorded as a component of AOCI until the underlying transaction is settled and recorded to the income statement. When the hedged item affects income, gains or losses are reclassified from AOCI to the Consolidated Statement of Operations as Cost of sales for foreign exchange contracts to purchase such foreign currency. Any ineffectiveness, if material, in the Company’s hedging relationships is recognized immediately as a loss, within the same income statement accounts as described above; to date, there has been no ineffectiveness. Changes in derivative balances impact the line items “Prepaid and other assets” and “Accrued expenses” on the Consolidated Balance Sheets and Statements of Cash Flows.

Note 15. Concentrations of Risks

The Company sells to customers globally and, as the Company generally does not require collateral from its customers, on a monthly basis the Company evaluates customer account balances in order to assess the Company’s financial risks of collection.  One customer, TTI, Inc., an electronics distributor, accounted for over 10% of the Company’s net sales in the quarters and six-month periods endedSeptember 30, 2017 and 2016.  There were no accounts receivable balances from any customer exceeding 10% of gross accounts receivable as of September 30, 2017 and March 31, 2017.

Electronics distributors are an important channel in the electronics industry and accounted for 39% and 46% of the Company’s net sales in the six-month periods ended September 30, 2017 and 2016, respectively.  As a result of the Company’s concentration of sales to electronics distributors, the Company may experience fluctuations in the Company’s operating results as electronics distributors experience fluctuations in end-market demand and/or adjust their inventory stocking levels. 

Legal Update

In July 2013, TOKIN was named as one of eight defendants in two purported U.S. class action antitrust lawsuits (In Re: Lithium Ion Batteries Antitrust Litigation, 13-MD-02420-YGR, United States District Court, Northern District of California) (the “Battery Class Action Suits”) regarding the sale of lithium ion batteries brought on behalf of direct product purchasers and indirect product purchasers. On April 12, 2017, motions to approve class certification on behalf of the direct product purchasers and indirect product purchasers plaintiffs were denied by the Court; plaintiffs were given leave to amend. On August 17, 2017, TOKIN reached a preliminary settlement by which, in consideration of the release of TOKIN and its subsidiaries from claims asserted in the Battery Class Action Suits, TOKIN agreed to pay $4.95 million to the settlement class of direct product purchasers. The settlement is subject to execution of a definitive agreement and court approval. Pursuant to the terms of the preliminary settlement, the settlement amount is payable within 21 days after preliminary court approval.

Beginning in March 2014, TOKIN and certain of its subsidiaries received inquiries, requests for information and other communications from government authorities in China, the United States, the European Commission, Japan, South Korea, Taiwan, Singapore and Brazil concerning alleged anti-competitive activities within the capacitor industry. 

On September 2, 2015, the United States Department of Justice announced a plea agreement with TOKIN in which TOKIN agreed to plead guilty to a one-count felony charge of unreasonable restraint of interstate and foreign trade and commerce in violation of Section 1 of the Sherman Act, and to pay a criminal fine of $13.8 million. The plea agreement was approved by the United States District Court, Northern District of California, on January 21, 2016. The fine is payable over five years in six installments of $2.3 million each, plus accrued interest. The first and second payments were made in February 2016 and January 2017, respectively, while the next payment is due in January 2018.

On December 9, 2015, the Taiwan Fair Trade Commission (“TFTC”) publicly announced that TOKIN would be fined 1,218.2 million New Taiwan dollars (“NTD”) (approximately U.S. $40.2 million) for violations of the Taiwan Fair Trade Act. Subsequently, the TFTC has reduced the fine to NTD609.1 million (approximately U.S. $20.1 million). In February 2016, TOKIN commenced an administrative suit in Taiwan, challenging the validity of the amount of the fine.

On March 29, 2016, the Japan Fair Trade Commission published an order by which TOKIN was fined ¥127.2 million (approximately U.S. $1.1 million) for violation of the Japanese Antimonopoly Act. Payment of the fine was made on October 31, 2016.

On July 15, 2016, TOKIN entered into definitive settlement agreements in two antitrust suits filed with the United States District Court, Northern District of California as In re: Capacitors Antitrust Litigation, No. 3:14-cv-03264-JD (the “Capacitor Class Action Suits”). Pursuant to the terms of the settlement, in consideration of the release of TOKIN and its subsidiaries (including TOKIN America, Inc.) from claims asserted in the Capacitor Class Action Suits, TOKIN will pay an aggregate $37.3 million to a settlement class of direct purchasers of capacitors and a settlement class of indirect purchasers of capacitors. Each of the respective class payments is payable in five installments, two of which were paid on or before

29

respective due dates of July 29, 2016 and 2017, the next two of which are due each year thereafter on the anniversary of the initial payment, and the final payment is due by December 31, 2019.

On July 27, 2016, Brazil’s Administrative Council for Economic Defense approved a cease and desist agreement with TOKIN in which TOKIN made a financial contribution of Brazilian Real 0.6 million (approximately U.S. $0.2 million) to Brazil’s Fund for Defense of Diffuse Rights.

The remaining governmental investigations are continuing at various stages. As of September 30, 2017, TOKIN’s accrual for antitrust and civil litigation claims totaled $81.6 million which is stated in the following line items, “Account payable” ($10.1 million), “Accrued expenses” ($35.4 million) and “Other non-current obligations” ($36.1 million) on the Condensed Consolidated Balance Sheets. This amount includes the best estimate of losses which may result from the ongoing antitrust investigations, civil litigation and claims. However, the actual outcomes could differ from what has been accrued. Additionally, under the terms of the TOKIN Purchase Agreement, TOKIN will be responsible for defending all suits, paying all expenses and satisfying all judgments to the extent arising out of or related the capacitor antitrust investigations and related litigation described above.

Accounting Policies and Estimates

The following discussion and analysis of financial condition and results of operations are based on the unaudited condensed consolidated financial statements included herein. Our significant accounting policies are described in Note 1 to the consolidated financial statements in our 2017 Annual Report. Our critical accounting policies are described under the caption “Critical Accounting Policies” in Item 7 of our 2017 Annual Report.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates, assumptions, and judgments based on historical data and other assumptions that management believes are reasonable. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. In addition, they affect the reported amounts of revenues and expenses during the reporting period.

Our judgments are based on management’s assessment as to the effect certain estimates, assumptions, future trends or events may have on the financial condition and results of operations reported in the unaudited condensed consolidated financial

31

statements. It is important that readers of these unaudited financial statements understand that actual results could differ from these estimates, assumptions, and judgments.

Business Overview

KEMET is a leading global manufacturer of a wide variety of capacitors, and, with the recent acquisition of TOKIN, electro-magnetic compatible devices, sensors and actuators. With respect to capacitors, we compete in the passive electronic component industry, specifically multilayer ceramic, tantalum, film and aluminum (solid & electrolytic) capacitors. Product offerings include surface mount capacitors, which are attached directly to the circuit board; leaded capacitors, which are attached to the circuit board using lead wires; and chassis-mount and other pin-through-hole board-mount capacitors, which utilize attachment methods such as screw terminal and snap-in.

Capacitors are electronic components that store, filter, and regulate electrical energy and current flow. As an essential passive component used in nearly all circuit boards, capacitors are typically used for coupling, decoupling, filtering, oscillating and wave shaping and are found in communication systems, servers, personal computers, tablets, cellular phones, automotive electronic systems, defense and aerospace systems, consumer electronics, power management systems and many other electronic devices and systems (basically anything that plugs in or has a battery).

KEMET’s capacitor product line consists of over 5 million distinct part configurations distinguished by various attributes, such as dielectric (or insulating) material, configuration, encapsulation, capacitance level and tolerance, voltage, operating temperature, performance characteristics and packaging. Because most of our customers have multiple capacitance requirements, often within each of their products, our broad product offering allows us to meet the majority of their needs independent of application and end use.

KEMET operates twenty-three production facilities in Europe, North America, and Asia, and employs approximately 15,000 employees worldwide. Commodity manufacturing has been substantially relocated to our lower-cost manufacturing facilities in Mexico, China and Europe. Production remaining in the United States focuses primarily on early-stage manufacturing of new products and specialty products for which customers are predominantly located in North America.

Our products are sold into a wide range of different end markets, including computing, industrial, telecommunications, transportation, consumer, defense and healthcare across all geographic regions. No single end market industry accounted for more than 30% of net sales although, one customer, a distributor, accounted for more than 10% of net sales in the six-month period ended September 30, 2017.  During the six-month period ended September 30, 2017 we introduced 9,118 new products of which 670 were first to market. In addition, we continue to focus on specialty products which accounted for 44% of our revenue over this period.

We believe the long-term demand for capacitors will grow on a regional and global basis due to a variety of factors, including increasing demand for and complexity of electronic products, growing demand for technology in emerging markets and the ongoing development of new solutions for energy generation and conservation.

On April 19, 2017, pursuant to a definitive TOKIN stock purchase agreement (the “TOKIN Purchase Agreement”) dated February 23, 2017, between KEMET Electronics Corporation (“KEC”), a wholly-owned subsidiary of KEMET, and NEC Corporation, KEC completed its acquisition of the remaining 66% economic interest in TOKIN Corporation ("TOKIN") (having previously held a 34% economic interest in TOKIN), and as a result TOKIN is now a 100% owned indirect subsidiary of KEMET (the “TOKIN Acquisition”). TOKIN is a manufacturer of tantalum capacitors, electro-magnetic and access devices. We believe the acquisition of TOKIN increases our market opportunity through the Electro-Magnetic Compatible (“EMC”) Devices and Sensor and Actuator markets.

The EMC business offers a broad line of noise management products. As circuits become more complex within a device, and the amount of information being communicated between devices increases at a dramatic rate, the quality of electronic signals becomes key to the integrity of the information being communicated. TOKIN EMC products play a key role in maintaining signal integrity across a number of end-markets including telecommunications, mobile computing, automotive and general industries. The sensor and actuator business manufactures products that sense and respond to human activity, physical vibration, and electric current. These products are found in home appliances, consumer devices and industrial electrical equipment. In addition, electromechanical actuation devices that are critical to the manufacture of semiconductor devices and the management of industrial and chemical gas flow are manufactured by the TOKIN subsidiary of KEMET. Sensors are an important family of devices as the “internet-of-things” continues to permeate everyday life.

We are organized into three segments: Solid Capacitors, Film and Electrolytic and Electro-magnetic, Sensors & Actuators (“MSA”).  Prior to the TOKIN Acquisition we reported two reportable segments, Solid Capacitors and Film and Electrolytic. However, in connection with the TOKIN Acquisition and effective beginning the quarter ended June 30, 2017,

32

TOKIN’s tantalum capacitor business is included within KEMET’s Solid Capacitors reportable segment and the remainder of TOKIN’s business formed the new reportable segment for KEMET, MSA.

The segments are responsible for their respective manufacturing sites as well as their respective research and development activity. The Company does not allocate corporate indirect selling, general and administrative (“SG&A”) or shared Research and development (“R&D”) expenses to the segments.  Results for the first quarter of fiscal year 2018 have been reclassified to conform to the current period presentation where certain regional SG&A amounts have been allocated to the impacted segments. 

Recent Developments and Trends

The following items are reflected in the financial statements for the quarter and six-month periods endedSeptember 30, 2017:

Warrant

On September 11, 2017, K Equity sold the remaining portion of the Platinum Warrant to UBS Securities LLC (the “Underwriter”), in connection with the offering of 8,416,814 shares of the Company’s common stock, at a public offering price of $21.57 per share. The Company filed a registration statement on Form S-3 to register the offer and resale by K Equity of these shares. The Company received approximately $8.8 million from the Underwriter in connection with the cash exercise of the Platinum Warrant for all 8,416,814 shares underlying the Platinum Warrant at an exercise price of $1.05 per share.

As of September 30, 2017, K Equity does not have any outstanding warrants for shares of the Company’s common stock.

TOKIN

On April 14, 2017, TOKIN closed on the sale of its electro-mechanical devices (“EMD”) business to NTJ Holdings 1 Ltd. (“NTJ”), a special purpose entity that is owned by funds managed or operated by Japan Industrial Partners, Inc. (“JIP”), pursuant to a master sale and purchase agreement (the “EMD Master Sale and Purchase Agreement”) previously entered into between TOKIN, NTJ and JIP (“Sale of EMD”). The initial selling price for EMD was JPY 48.2 billion, or approximately $431.0 million, using the March 31, 2017 exchange rate of 111.823 Japanese Yen to 1.00 U.S. Dollar, and is subject to certain working capital adjustments pursuant to the EMD Master Sale and Purchase Agreement. At the closing of the Sale of EMD, TOKIN used a portion of the sale proceeds to repay debt related to a shareholder loan from NEC. The TOKIN historical balance sheet was adjusted to reflect the removal of net assets sold and other items directly impacted by the Sale of EMD. Additionally, due to KEMET’s 34% equity interest in TOKIN held as of the closing, adjustments have been made to reflect KEMET’s accounting for the Sale of EMD in accordance with the equity method of accounting; see the line item "Equity income (loss) from equity method investments" on the Condensed Consolidated Statement of Operations.

On April 19, 2017, pursuant to the TOKIN Purchase Agreement dated February 23, 2017 between KEC and NEC, KEC completed its acquisition, subject to final purchase price adjustment, of the remaining 66% economic interest in TOKIN, and as a result TOKIN is now a 100% owned indirect subsidiary of KEMET. Under the terms of the TOKIN Purchase Agreement, KEC initially paid NEC JPY 16.2 billion, or approximately $148.6 million (using the April 19, 2017 exchange rate of 109.007 Japanese Yen to 1.00 U.S. Dollar), for all of the outstanding shares of TOKIN it did not already own. The acquisition price was subject to working capital adjustments pursuant to the EMD Master Sale and Purchase Agreement, as a result the acquisition price was increased by JPY0.3 billion, or approximately $3.0 million (using the September 30, 2017 exchange rate of 112.502 Japanese Yen to 1.00 U.S. Dollar) in the second quarter of fiscal year 2018.

As part of the acquisition, KEMET recorded acquisition gains totaling $136.9 million consisting of the following: a preliminary gain of $72.4 million to mark its thirty-four percent interest in TOKIN to fair value and a $64.4 million preliminary gain on the acquisition of TOKIN for the quarter ended September 30, 2017. The Company continues to evaluate the calculation of acquisition related gains and, as such, these preliminary numbers may change in the future.

We believe the acquisition of TOKIN will expand KEMET’s geographic presence, combining KEMET’s presence in the western hemisphere and TOKIN’s excellent position in Asia to enhance customer reach and create an entrance into Japan for KEMET. We believe TOKIN’s product portfolio is a strong complement to KEMET’s existing product portfolio. KEMET believes the combination creates a leader in the combined polymer and tantalum capacitors market. The acquisition also enhances KEMET’s product diversification with entry into EMC and sensors. With the increased scale, the Company anticipates optimizing costs through competitive raw materials sourcing and maximizing operating efficiencies. Consistent with expectations, the acquisition has been accretive to earnings with improvement in Adjusted EBITDA and cash flow. Effective for the quarter ended June 30, 2017, TOKIN’s tantalum capacitor business was incorporated into KEMET’s Solid Capacitors reportable segment and the remainder of TOKIN’s business formed the new reportable segment for KEMET, MSA.

33

Long-Term Debt

On April 28, 2017, KEMET entered into a Term Loan Credit Agreement (the “Term Loan Credit Agreement”) by and among the Company, KEC (together with the Company, the “Borrowers”), Bank of America, N.A., as the Administrative Agent and Collateral Agent, Merrill Lynch, Pierce, Fenner & Smith Incorporated, as sole lead arrange and bookrunner and various other lenders thereto from time to time. The Term Loan Credit Agreement provides for a $345 million term loan facility. In addition, the Borrowers may request incremental term loan commitments in an aggregate amount not to exceed $50 million (together with the initial $345 million term loan, the “Term Loans”). The proceeds were used, together with cash on hand, to fund the redemption of all of KEMET’s outstanding 10.5% Senior Notes, which were also called for redemption on April 28, 2017.

In connection with the closing of the new Term Loan Credit Agreement, KEC also entered into Amendment No. 9 to Loan and Security Agreement, Waiver and Consent, dated as of April 28, 2017 (the “Loan Amendment”), which increases the revolving credit facility amount to $75 million and provides KEC with lower applicable interest rate margins and the ability to complete the refinancing. As part of the overall refinancing, KEC also repaid all amounts outstanding under the Loan Amendment.

Please see Note 3, “Debt” to our consolidated financial statements for additional information.

Outlook

For the third quarter of fiscal year 2018, we expect net sales to be within the $288 million to $300 million range, gross margin as a percentage of net sales are expected to be between 26.5% and 27.5%, SG&A expenses are expected to be between $39.5 million and $41.0 million, R&D expenses are expected to be approximately $9.2 million to $9.8 million and income taxes are forecasted to be between $3.2 million and $3.8 million. We expect to spend in the range of $15 million to $20 million in capital expenditures for the third quarter of fiscal year 2018 and $50 to $60 million for the full fiscal year 2018.

⁽¹⁾ Quarter ended September 30, 2016 adjusted due to the adoption of ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost

Net Sales

Net sales for the quarter ended September 30, 2017 of $301.5 millionincreased$114.2 million or 60.9% from $187.3 million for the quarter ended September 30, 2016. Solid Capacitor net sales increased $48.6 million, Film and Electrolytic net sales increased $3.2 million, and net sales for our new segment MSA were $62.3 million for the quarter ended September 30, 2017. Prior to the TOKIN acquisition on April 19, 2017, the Company did not have any MSA sales.

The increase in Solid Capacitors net sales is primarily driven by the addition of revenue of $34.5 million in connection with the TOKIN acquisition and, to a lesser extent, an increase in sales in the legacy products distributor and EMS ("Electronics Manufacturing Services") channels. The increase in distributor channel sales was somewhat offset by a decrease in the original equipment manufacturers (“OEMs”) channel across all regions for legacy Tantalum products. Included in the net sales increase was a favorable impact of $1.1 million from foreign currency exchange due primarily to the change in the value of the Euro compared to the U.S. dollar.

For Film and Electrolytic, the increase in net sales was primarily driven by increased net sales in the distributor channel across the APAC and Europe, the Middle East and Africa (“EMEA”) regions as well as the OEM channel of the Asia and Pacific Rim ("APAC") region and EMS in all regions. Included in the net sales increase was a favorable impact of $1.4 million from foreign currency exchange due primarily to the change in the value of the Euro compared to the U.S. dollar.

The following table reflects the percentage of net sales by region for the quarters ended September 30, 2017 and 2016:

	Quarters Ended September 30,
	2017		2016
North America and South America (“Americas”)	20	%	30	%
EMEA	22	%	32	%
Japan and Korea ("JPKO")	15	%	—	%
APAC	43	%	38	%
	100	%	100	%

The following table reflects the percentage of net sales by channel for the quarters ended September 30, 2017 and 2016; the significant increase in percentage of net sales in the OEM channel is attributable to the impact of the TOKIN acquisition:

	Quarters Ended September 30,
	2017		2016
Distributor	36	%	46	%
EMS	15	%	20	%
OEM	49	%	34	%
	100	%	100	%

Gross Margin

Gross margin for the quarter ended September 30, 2017 of $85.1 million (28.2% of net sales) increased $38.6 million or 82.9% from $46.5 million (24.8% of net sales) for the quarter ended September 30, 2016, and gross margin as a percentage of net sales improved 340 basis points. TOKIN contributed $25.6 million in additional gross margin during the quarter ended September 30, 2017. Legacy KEMET gross margin increased $13.0 million or approximately 420 basis points, primarily driven by an increase in net sales as well as from continued variable margin improvement due to our restructuring activities, vertical integration, the favorable foreign currency impact on manufacturing costs, and manufacturing process improvements as a result of our cost reduction activities.

Selling, General and Administrative Expenses (“SG&A”)

SG&A expenses of $42.4 million (14.1% of net sales) for the quarter ended September 30, 2017increased$16.6 million or 64.1% from $25.8 million (13.8% of net sales) for the quarter ended September 30, 2016. The increase was attributable primarily to $12.2 million in selling, general and administrative expenses incurred by TOKIN for the quarter ended September 30, 2017. In addition the increase also corresponds with a $3.7 million in increased payroll-related expenses and benefits and $1.8 million in increased office equipment, information technology consulting, and software lease expenses. These increases were partially offset by a $1.8 million decrease in ERP integration and technology transition costs.

Research and Development (“R&D”)

R&D expenses of $9.7 million (3.2% of net sales) for the quarter ended September 30, 2017increased$2.6 million or 37.6% compared to $7.0 million (3.7% of net sales) for the quarter ended September 30, 2016. The increase was primarily related to $2.6 million in R&D expenses incurred by TOKIN for the quarter ended September 30, 2017.

Restructuring Charges

Restructuring charges of $1.4 million for the quarter ended September 30, 2017decreased$2.6 million or 65.2% from $4.0 million for the quarter ended September 30, 2016.  

We incurred $1.4 million in restructuring charges in the quarter ended September 30, 2017 including $0.9 million in personnel reduction costs and $0.5 million manufacturing relocation and exit costs. The personnel reduction costs of $0.9 million are due to U.S. headcount reductions related to the relocation of global marketing, finance and accounting, and information technology functions to the Company’s Fort Lauderdale, Florida office from Simpsonville, South Carolina. The manufacturing relocation and exit costs of $0.5 million primarily consist of $0.4 million in expenses related to the relocation of the K-Salt operations to the existing Matamoros, Mexico plant and $0.1 million in exit costs related to the shut-down of operations for KFM in Knoxville, Tennessee.

36

We incurred $4.0 million in restructuring charges in the quarter ended September 30, 2016 including $1.4 million in personnel reduction costs and $2.6 million in manufacturing relocation and exit costs. The personnel reduction costs of $1.4 million consist of $0.4 million in headcount reductions related to the shut-down of operations for KFM in Knoxville, Tennessee, $0.4 million related to the consolidation of certain Solid Capacitor manufacturing in Matamoros, Mexico, $0.3 million in U.S. headcount reductions related to the relocation of global marketing functions to the Company’s Fort Lauderdale, Florida office, $0.2 million related to overhead reductions corresponding with the relocation of research and development (“R&D”) operations from Weymouth, England to Evora, Portugal, and $0.1 million in manufacturing headcount reductions related to the relocation of the K-Salt operations to the existing Matamoros, Mexico plant.

The manufacturing relocation and exit costs of $2.6 million primarily consists of $2.2 million related to contract termination costs related to the shut-down of operations for KFM, $0.3 million related to transfers of Film and Electrolytic production lines and R&D functions to lower cost regions, and $0.1 million related to the transfer of certain Tantalum production from Simpsonville, South Carolina to Victoria, Mexico.

Write Down and Disposal of Long-Lived Assets

We did not record any significant write down and disposal of long-lived assets in the quarter ended September 30, 2017.

In the quarter ended September 30, 2016 we recorded a write down and disposal of long-lived assets of $6.3 million due to the following two actions: KEC made the decision to shut-down operations of its wholly-owned subsidiary, KFM, and the relocation of equipment at our leased K-Salt facility to our existing Matamoros, Mexico facility. Operations at KFM’s Knoxville, Tennessee plant ceased as of October 31, 2016. During the second fiscal quarter ending September 30, 2016, we incurred impairment charges totaling $4.1 million relating to the shutdown of KFM comprised of $3.0 million for the write down of property, plant and equipment and $1.1 million for the write down of intangible assets and $2.1 million related to impairment charges for the relocation of equipment at our leased K-Salt facility to our existing Matamoros, Mexico facility.

Operating Income (Loss)

Operating income of $31.6 million for the quarter ended September 30, 2017improved$28.3 million from operating income of $3.4 million for the quarter ended September 30, 2016.  The improvement was primarily attributable to a $38.6 millionimprovement in gross margin, a $6.3 milliondecrease in write down and disposal of long-lived assets, and a $2.6 milliondecrease in restructuring charges. These improvements to operating income were partially offset by a $16.6 millionincrease in SG&A expenses and a $2.6 millionincrease in R&D expenses.

Non-Operating (Income) Expense, Net

Non-operating (income) expense was a net expense of $16.1 million for the quarter ended September 30, 2017 compared to a net expense of $7.7 million for the quarter ended September 30, 2016. The $8.4 million increase in expense is primarily attributable to $8.0 million in litigation related accruals; a $2.6 million net unfavorable change in foreign currency exchange gain/(loss), which was primarily due to the change in the value of the Euro, Japanese Yen, Chinese Yuan Renminbi, and Mexican Peso compared to the U.S. dollar; and a $1.6 million increase in the value of the NEC TOKIN option during the quarter ended September 30, 2016. These increases in expense were partially offset by a $1.3 million acquisition gain and $2.6 million in decreased net interest and amortization expense under the new Term Loan and Credit Agreement as compared with net interest and amortization expense under the Senior Notes.

Income Taxes

Income tax expense of $2.9 million for the quarter ended September 30, 2017increased$2.1 million compared to income tax expense of $0.8 million for the quarter ended September 30, 2016. Income tax expense of $2.7 million for the quarter ended September 30, 2017 related to foreign operations, $0.1 million related to federal income tax expense and $0.1 million related to state income tax expense.  Income tax expense of $0.8 million for the quarter ended September 30, 2016 related to foreign operations.

There was no U.S. federal income tax benefit from net operating losses for the quarters ended September 30, 2017 and 2016 due to a valuation allowance recorded on deferred tax assets.

Solid Capacitors net sales of $191.3 million for the quarter ended September 30, 2017increased$48.6 million or 34.1% from $142.6 million for the quarter ended September 30, 2016. The increase in net sales was primarily driven by the addition of TOKIN revenue of $34.5 million in connection with the TOKIN acquisition and, to a lesser extent, an increase in sales in the legacy products distributor channel and EMS channels. The increase in distributor and EMS channel sales was somewhat offset by a decrease in sales in the OEM channel across all regions for legacy Tantalum products. Included in the overall increase in net sales was a favorable impact of $1.1 million from foreign currency exchange primarily due to the change in the value of the Euro compared to the U.S. dollar.

38

Segment Operating Income (Loss)

Segment operating income of $56.7 million for the quarter ended September 30, 2017improved$21.1 million or 59.4% from $35.6 million in the quarter ended September 30, 2016. The increase in operating income is primarily a result of a $22.4 million improvement in gross margin. TOKIN contributed $10.9 million in additional gross margin during the quarter ended September 30, 2017. Legacy KEMET gross margin increased $11.5 million or approximately 460 basis points, primarily driven by an increase in net sales and continued variable margin improvement due to our restructuring activities, vertical integration, the favorable foreign currency impact on manufacturing costs, and manufacturing process improvements as a result of our cost reduction activities. The increase was also attributable to a $2.1 million decrease in the write down of long-lived assets. Partially offsetting these improvements was a $2.7 million increase in SG&A, and a $0.8 millionincrease in R&D for the quarter ended September 30, 2017 compared to the quarter ended September 30, 2016 primarily due to the TOKIN acquisition.

Film and Electrolytic

Net Sales

Net sales of $575.5 million for the six-month period ended September 30, 2017increased$203.2 million or 54.6% from $372.2 million for the six-month period ended September 30, 2016. Solid Capacitor net sales increased $88.8 million, Film and Electrolytic net sales increased$7.8 million, and net sales for our new segment MSA were $106.6 million. Prior to the TOKIN acquisition on April 19, 2017, the Company did not have any MSA sales.

The increase in Solid Capacitors net sales was primarily driven by the addition of revenue of $62.0 million in connection with the TOKIN acquisition and, to a lesser extent, an increase in the legacy products sales in the distributor and EMS channels. The increase in distributor and EMS channel sales was somewhat offset by a decrease in sales in the OEMs channel sales across all regions for legacy Tantalum products. In addition, Solid Capacitor net sales were favorably impacted by $0.4 million from foreign currency exchange primarily due to the change in the value of the Euro compared to the U.S. dollar.

40

The increase in Film and Electrolytic net sales was driven primarily by increased net sales in the distributor channel across the APAC and EMEA regions, as well as the OEM channel of the APAC region and the EMS channel across all regions. In addition, there was a favorable impact of $0.3 million from foreign currency exchange primarily due to the change in the value of the Euro compared to the U.S. dollar.

The following table reflects the percentage of net sales by region for the six-month periods ended September 30, 2017 and 2016:

Gross Margin

Gross margin of $159.5 million (27.7% of net sales) for the six-month period ended September 30, 2017increased$70.2 million or 78.7% from $89.3 million (24.0% of net sales) for the six-month period ended September 30, 2016 and gross margin as a percentage of net sales improved 370 basis points. TOKIN contributed $42.1 million in additional gross margin during the six-month period ended September 30, 2017. Legacy KEMET gross margin increased $28.1 million or approximately 480 basis points, primarily driven by the increase in net sales and an improvement in variable margin corresponding with our restructuring plan, cost reduction activities, vertical integration, the favorable foreign currency impact to manufacturing costs, and manufacturing process improvements as a result of our cost reduction activities.

Selling, General and Administrative Expenses

SG&A expenses of $78.0 million (13.6% of net sales) for the six-month period endedSeptember 30, 2017increased$26.4 million or 51.3% compared to $51.6 million (13.9% of net sales) for the six-month period endedSeptember 30, 2016. The increase was attributable primarily to $20.5 million in SG&A expenses incurred by TOKIN for the six-month period endedSeptember 30, 2017. In addition, the increase was related to $5.7 million in increased payroll-related expenses and benefits; $2.7 million increase in office equipment and hardware and software lease expenses; $1.2 million increase in professional fees; and $0.7 million increase in travel related expenses. These increases were partially offset by a $3.6 million decrease in ERP integration and technology transition costs and an $0.8 million decrease in legal expenses.

Research and Development

R&D expenses of $19.1 million (3.3% of net sales) for the six-month period endedSeptember 30, 2017increased$5.1 million or 36.6% compared to $13.9 million (3.7% of net sales) for the six-month period endedSeptember 30, 2016. The increase was primarily related to $4.7 million in R&D expenses incurred by TOKIN for the six-month period endedSeptember 30, 2017.

41

Restructuring Charges

Restructuring charges of $3.0 million for the six-month period ended September 30, 2017decreased$1.7 million or 35.9% from $4.7 million for the six-month period ended September 30, 2016. 

Restructuring charges in the six-month period endedSeptember 30, 2017 included $1.1 million of personnel reduction costs and $1.9 million of manufacturing relocation and exit costs. The personnel reduction costs of $1.1 million are due to U.S. headcount reductions related to the relocation of global marketing, finance and accounting, and information technology functions to the Company’s Fort Lauderdale, Florida office from Simpsonville, South Carolina. The manufacturing relocation and exit costs of $1.9 million primarily consist of $0.9 million in lease termination penalties related to the relocation of global marketing, finance and accounting, and information technology functions to the Company’s Fort Lauderdale, Florida office, $0.6 million in expenses related to the relocation of the K-Salt operations to the existing Matamoros, Mexico plant, $0.3 million in exit costs related to the shut-down of operations for KFM in Knoxville, Tennessee, and $0.1 million related to the transfer of certain Tantalum production from Simpsonville, South Carolina to Victoria, Mexico.

Restructuring charges in the six-month period endedSeptember 30, 2016 included $2.1 million of personnel reduction costs and $2.6 million of manufacturing relocation and exit costs. The personnel reduction costs of $2.1 million consist of $0.5 million related to the consolidation of certain Solid Capacitor manufacturing in Matamoros, Mexico; $0.4 million in headcount reductions related to the shut-down of operations for KFM in Knoxville, Tennessee; $0.3 million for overhead reductions in Sweden; $0.3 million in U.S. headcount reductions related to the relocation of global marketing functions to the Company’s Fort Lauderdale, Florida office; $0.2 million related to overhead reductions as we relocate the R&D operations from Weymouth, England to Evora, Portugal; $0.2 million related to headcount reductions in Europe (primarily Italy and Landsberg, Germany) corresponding with the relocation of certain production lines and laboratories to lower cost regions; and $0.1 million in manufacturing headcount reductions related to the relocation of the K-Salt operations to the existing Matamoros, Mexico plant. The manufacturing relocation and exit costs of $2.6 million primarily consists of $2.2 million related to contract termination costs related to the shut-down of operations for KFM, $0.3 million related to transfers of Film and Electrolytic production lines and R&D functions to lower cost regions, and $0.1 million related to the transfer of certain Tantalum production from Simpsonville, South Carolina to Victoria, Mexico.

Write Down and Disposal of Long-Lived Assets

We did not record any significant write down and disposal of long-lived assets in the six-month period endedSeptember 30, 2017.

In the six-month period endedSeptember 30, 2016 we recorded a write down and disposal of long-lived assets of $6.4 million due primarily to the following two actions: KEC made the decision to shut-down operations of its wholly-owned subsidiary, KFM, and the relocation of equipment at our leased K-Salt facility to our existing Matamoros, Mexico facility. Operations at KFM’s Knoxville, Tennessee plant ceased as of October 31, 2016. During the second fiscal quarter ending September 30, 2016, we incurred impairment charges totaling $4.1 million relating to the shutdown of KFM comprised of $3.0 million for the write down of property, plant and equipment and $1.1 million for the write down of intangible assets and $2.1 million related to impairment charges for the relocation of equipment at our leased K-Salt facility to our existing Matamoros, Mexico facility.

Operating Income (Loss)

Operating income of $59.4 million for the six-month period ended September 30, 2017 improved $46.8 million from operating income of $12.7 million for the six-month period ended September 30, 2016. The improvement was primarily attributable to a $70.2 millionimprovement in gross margin, a $6.4 milliondecrease in write down and disposal of long-lived assets and a $1.7 milliondecrease in restructuring charges. These improvements to operating income were partially offset by a $26.4 millionincrease in SG&A expense and a $5.1 millionincrease in R&D expenses.

Non-Operating (Income) Expense, Net

Non-operating (income) expense, net improved to a gain of $102.4 million for the six-month period endedSeptember 30, 2017, compared to an expense of $27.6 million for the six-month period endedSeptember 30, 2016. The $130.1 million change is primarily due to the recognition of a $136.9 million gain on acquisition, a $10.4 million decrease in the value of the NEC TOKIN option during the six-month period endedSeptember 30, 2016, and $1.7 million in decreased net interest and amortization expense under the new Term Loan and Credit Agreementfor the six-month period endedSeptember 30, 2017as compared with net interest and amortization expense under the Senior Notesfor the six-month period endedSeptember 30, 2016.Partially offsetting these favorable changes were the following unfavorable changes: a $9.6 million net unfavorable change in foreign currency exchange gain/(loss), which was primarily due to the change in the value of the Euro, Japanese Yen,

42

Chinese Yuan Renminbi, and Mexican Peso compared to the U.S. dollar; $8.0 million in antitrust litigation fines, and a $0.5 million loss on early extinguishment of debt.

Income Taxes

Income tax expense of $4.0 million for the six-month period endedSeptember 30, 2017 increased $1.4 million compared to income tax expense of $2.6 million for the six-month period ended September 30, 2016. Income tax expense of $4.0 million for the six-month period endedSeptember 30, 2017 was comprised of $3.6 million of income tax expense related to foreign operations, $0.2 million of federal income tax expense and $0.2 million of state income tax expense. Income tax expense of $2.6 million for the six-month period ended September 30, 2016 related to foreign operations.

There was no U.S. federal income tax benefit from net operating losses for the six-month periods ended September 30, 2017 and 2016 due to a valuation allowance on deferred tax assets.

Equity Income (Loss) from Equity Method Investments

Equity income related to our 34% economic interest in TOKIN increased by $75.2 million to equity income of $75.6 million for the six-month period ended September 30, 2017 compared to equity income of $0.4 million for the six-month period ended September 30, 2016. The change was primarily due to equity income of $84.2 million related to our 34% economic interest in TOKIN for the 19 day period ended April 19, 2017 which included the gain on the sale of the EMD business. Offsetting this favorable item was a $9.0 million removal of the balance of the cost basis of the portion of equity investment related to the EMD division which was established at the time of initial acquisition of 34% of TOKIN.

Solid Capacitors

The following table sets forth net sales, operating income and operating income as a percentage of net sales for our Solid Capacitors segment for the six-month periods ended September 30, 2017 and 2016 (amounts in thousands, except percentages):

	Six-Month Periods Ended September 30,
	2017				2016
	Amount		% to Net Sales		Amount		% to Net Sales
Tantalum product line net sales	$	241,854			$	166,185
Ceramic product line net sales	131,532				118,400
Solid Capacitors net sales	$	373,386			$	284,585
Solid Capacitors operating income (loss)	$	109,426	29.3	%	$	70,841	24.9	%

Net Sales

Solid Capacitors net sales of $373.4 million for the six-month period ended September 30, 2017increased$88.8 million or 31.2% from $284.6 million for the six-month period ended September 30, 2016. The increase in net sales was primarily driven by the addition of TOKIN revenue of $62.0 million in connection with the TOKIN acquisition and to a lesser extent, an increase in sales in the legacy products distributor and EMS channels. The increase in distributor and EMS channel sales was somewhat offset by a decrease in the OEM channel across the APAC and Americas regions for legacy Tantalum products. Included in the overall increase in net sales for Solid Capacitors was a favorable impact of $0.4 million from foreign currency exchange primarily due to the change in the value of the Euro compared to the U.S. dollar.

Segment Operating Income (Loss)

Segment operating income of $109.4 million for the six-month period ended September 30, 2017increased$38.6 million or 54.5% from $70.8 million for the six-month period ended September 30, 2016. The increase in operating income was attributable primarily to an increase in gross margin of $43.5 million. TOKIN contributed $20.3 million in additional gross margin during the six-month period ended September 30, 2017. Legacy KEMET gross margin increased $23.2 million or approximately 490 basis points, primarily driven by an increase in net sales, cost improvements in vertical integration, favorable foreign currency impact to manufacturing costs, and manufacturing process improvements as a result of our cost reduction activities. In addition, there was a $2.1 million reduction in non-cash impairment charges. Partially offsetting these improvements were a $5.1 million increase in SG&A and a $2.0 million increase in R&D expenses primarily due to the TOKIN acquisition.

Film and Electrolytic

The following table sets forth net sales, operating income (loss) and operating income (loss) as a percentage of net sales for our Film and Electrolytic segment for the six-month periods ended September 30, 2017 and 2016 (amounts in thousands, except percentages):

	Six-Month Periods Ended September 30,
	2017				2016
	Amount		% to Net Sales		Amount			% to Net Sales
Net sales	$	95,438			$	87,658
Operating income (loss)	3,614		3.8	%	(8,478		)	(9.7	)%

Net Sales

Film and Electrolytic net sales of $95.4 million for the six-month period ended September 30, 2017increased$7.8 million or 8.9% from $87.7 million for the six-month period ended September 30, 2016. The increase in net sales was primarily driven by increased net sales in the distributor channel across the APAC and EMEA regions as well as the OEM channel of the APAC region and EMS across all regions. In addition, there was a favorable impact of $0.3 million from foreign currency exchange primarily due to the change in the value of the Euro compared to the U.S. dollar.

Segment Operating Income (Loss)

Segment operating income of $3.6 million for the six-month period ended September 30, 2017increased$12.1 million from segment operating loss of $8.5 million for the six-month period ended September 30, 2016.  The increase was primarily attributable to a $4.5 million increase in gross margin driven by higher net sales as well as the benefit of the completed restructuring actions. The increase was also attributable to the following declines in the six-month period ended September 30, 2017 compared to the six-month period ended September 30, 2016: write down and disposal of long-lived assets of $4.3 million, restructuring charges of $3.4 million and R&D expenses of $0.3 million. These improvements were partially offset by a $0.5 million increase in SG&A charges.

Electro-magnetic, Sensors & Actuators

The following table sets forth net sales, operating income (loss), and operating income (loss) as a percentage of net sales for our MSA segment for the six-month period ended September 30, 2017 (amounts in thousands, except percentages). MSA is a new segment which is comprised of electro magnetically compatible materials and components, Piezo materials and actuators and various types of sensors acquired in connection with the TOKIN Acquisition on April 19, 2017:

	Six-Month Periods Ended September 30,
	2017
	Amount		% to Net Sales
Net sales	$	106,647
Operating income (loss)	8,123		7.6	%

Net Sales

MSA had net sales of $106.6 million for the six-month period ended September 30, 2017. All sales are from the newly acquired TOKIN business.

Segment Operating Income (Loss)

Segment operating income was $8.1 million for the six-month period ended September 30, 2017. All activity is from the newly acquired TOKIN business.

Liquidity and Capital Resources

Our liquidity needs arise from working capital requirements, capital expenditures, acquisitions, principal and interest payments on debt, and costs associated with the implementation of our restructuring plans. Historically, our cash needs have been met by cash flows from operations, borrowings under our loan agreements, and existing cash balances.

10.5% Senior Notes

On April 28, 2017, the Company repurchased and retired the full outstanding balance of $353.0 million of its 10.5% Senior Notes due May 1, 2018 (the “10.5% Senior Notes”). The Company had interest payable related to the 10.5% Senior Notes included in the line item “Accrued expenses” on its Condensed Consolidated balance sheets of zero and $15.4 million as of September 30, 2017 and March 31, 2017, respectively.

Term Loan Credit Agreement

On April 28, 2017, KEMET entered into a Term Loan Credit Agreement (the “Term Loan Credit Agreement”) by and among the Company, KEC (together with the Company, the “Borrowers”), Bank of America, N.A. as the Administrative Agent and Collateral Agent, Merrill Lynch, Pierce, Fenner & Smith Incorporated, as sole lead arranger and bookrunner and various other lenders thereto from time to time. The Term Loan Credit Agreement provides for a $345 million term loan facility. In addition, the Borrowers may request incremental term loan commitments in an aggregate amount not to exceed $50 million (together with the initial $345 million term loan, the “Term Loans”). The proceeds were used, together with cash on hand, to fund the redemption of all of KEMET’s outstanding 10.5% Senior Notes, which were also called for redemption on April 28, 2017. The Term Loans were made with an original issue discount of 300 bps. At the Company’s election, the Term Loans may be made as either Base Rate Term Loans or LIBO Rate Term Loans (each as defined in the Term Loan Credit Agreement). The applicable margin for term loans is 5.0% for Base Rate Term Loans and 6.0% for LIBO Rate Term Loans. All LIBO Rate Term Loans are subject to a pre-margin floor of 1.00%. The Term Loan Credit Agreement contains customary covenants and events

of default. The Company also entered into the Term Loan Security Agreement dated as of April 28, 2017 (the “Security Agreement”), by and among the Company, KEC and certain other subsidiaries of the Company, and Bank of America, N.A., as collateral agent, pursuant to which the Company’s obligations under the Term Loan Credit Agreement are secured by a pledge of 65% of the outstanding voting stock of certain first-tier subsidiaries organized in Italy, Japan, Mexico and Singapore, and a second lien pledge on the collateral securing KEMET’s revolving credit facility. The obligations of the Company under the Term Loan Credit Agreement are guaranteed by certain of its subsidiaries, including KRC Trade Corporation, KEMET Services Corporation, KEMET Blue Powder Corporation and The Forest Electric Company. The Term Loans mature April 28, 2024, and may be extended in accordance with the Term Loan Credit Agreement. The Company may prepay loans under the Term Loan Credit Agreement at any time, subject to certain notice requirements and certain prepayment premiums during the first two years. On a quarterly basis the Company must repay 1.25% of the aggregate principal amount of the initial $345 million term loan, or $4.3 million, beginning September 29, 2017.

The Company currently pays interest on the Term Loan Security Agreement on a monthly basis due to favorable LIBO rates, and as such had no interest payable related to the Term Loan Security Agreement included in the line item “Accrued expenses” on its Condensed Consolidated balance sheets as of September 30, 2017 and March 31, 2017.

Revolving Line of Credit

In connection with the closing of the new Term Loan Credit Agreement, KEC also entered into Amendment No. 9 to Loan and Security Agreement, Waiver and Consent, dated as of April 28, 2017, by and among KEC, the other borrowers named therein, the financial institutions party thereto as lenders and Bank of America, N.A., as agent for the lenders (the “Loan Amendment”). The Loan Amendment increases the facility amount to $75.0 million and provides KEC with lower applicable interest rate margins and the ability to complete the refinancing. As part of the overall refinancing, KEC also repaid all amounts outstanding under the Loan Amendment.

There were no borrowings under the revolving line of credit as of September 30, 2017.

Short-Term Liquidity

Cash and cash equivalents as of September 30, 2017 of $253.7 millionincreased$143.9 million from $109.8 million as of March 31, 2017. Our net working capital (current assets less current liabilities) as of September 30, 2017 was $384.8 million compared to $248.9 million as of March 31, 2017. Cash and cash equivalents held by our foreign subsidiaries totaled $154.5 million and $35.0 million at September 30, 2017 and March 31, 2017, respectively, with the increase primarily driven by cash holdings of TOKIN. Our operating income outside the U.S. is no longer deemed to be permanently reinvested in foreign jurisdictions. As a result, we set up a deferred tax liability as of March 31, 2015 on the undistributed foreign earnings which was offset by a reduction in the valuation allowance on our deferred tax assets. However, we currently do not intend nor foresee a need to repatriate cash and cash equivalents held by foreign subsidiaries. If these funds are needed for our operations in the U.S., we may be required to accrue U.S. withholding taxes on the distributed foreign earnings.

Based on our current operating plans, we believe domestic cash and cash equivalents are sufficient to fund our operating requirements for at least the next twelve months, including $24.5 million in interest payments, $17.3 million in debt principal payments, $50 to $60 million in expected capital expenditures and $1.8 million in restructuring payments. As of September 30, 2017, our borrowing capacity, which is based on factors including outstanding eligible accounts receivable, inventory and equipment collateral, under the revolving line of credit was $71.7 million. The revolving line of credit expires on April 28, 2022.

Should we require more capital than is generated by our operations or available through our revolving line of credit, we could attempt to raise capital through debt issuances or the sale of certain non-core assets. However, due to market conditions beyond our control, there can be no assurance that we would be able to complete such an offering or sale transaction. The incurrence of additional debt may result in increased interest expense.

Cash and cash equivalents increased$143.9 million for the six-month period ended September 30, 2017, as compared to a increase of $9.7 million during the six-month period ended September 30, 2016.

The following table provides a summary of cash flows for the periods presented (amounts in thousands):

	Six-Month Periods Ended September 30,
	2017			2016
Net cash provided by (used in) operating activities	$	40,067		$	23,043
Net cash provided by (used in) investing activities	149,899			(10,344		)
Net cash provided by (used in) financing activities	(47,729		)	(2,498		)
Effect of foreign currency fluctuations on cash	1,662			(452		)
Net increase (decrease) in cash and cash equivalents	$	143,899		$	9,749

Operating

Cash provided by operating activities during the six-month period ended September 30, 2017 of $40.1 million increased $17.0 million compared to cash provided by operating activities of $23.0 million in the six-month period ended September 30, 2016. Contributing to the positive changes in cash was a $30.4 million increase in operating cash flows led by an improvement in net income (loss) net of the following non-cash income statement items: depreciation and amortization, change in value of TOKIN options, (income) loss from equity-method investments, acquisition gains, non-cash debt and financing costs, stock-based compensation expense, receivable write down, write down and disposals of long-lived assets, pension and other post-retirement benefits, and deferred income taxes for the six-month period ended September 30, 2017 compared to the six-month period ended September 30, 2016.

Also contributing to the positive changes in cash was a $19.4 million improvement in cash from operating assets, excluding foreign currency exchange. In the six-month period ended September 30, 2017, a decrease in accounts receivable generated $32.9 million in cash, compared to the six-month period ended September 30, 2016, during which a decrease in accounts receivable generated $4.8 million in cash. The primary reason for the change in accounts receivable is due to the timing of customer receipts. Additionally, in the six-month period ended September 30, 2017, a decrease in prepaid expenses and other assets generated $1.5 million in cash, compared to the six-month period ended September 30, 2016, during which an increase in prepaid expenses and other assets used $5.5 million in cash. Offsetting these improvements, in the six-month period ended September 30, 2017, an increase in inventory used $13.3 million in cash, compared to the six-month period ended September 30, 2016, during which a decrease in inventory generated $2.4 million in cash. The primary reason for the change in inventory is increased customer demand.

    Offsetting the positive changes in cash was a $32.7 milliondecrease in cash from operating liabilities, excluding foreign currency exchange. In the six-month period ended September 30, 2017, a decrease in accounts payable used $14.5 million in cash, compared to the six-month period ended September 30, 2016, during which an increase in accounts payable generated $0.5 million in cash. The primary reason for the change in accounts payable is due to the timing of supplier payments. Additionally, in the six-month period ended September 30, 2017, a decrease in accrued expenses used $20.0 million in cash, compared to the six-month period ended September 30, 2016, during which a decrease in accrued expenses used $2.1 million in cash. The primary reason for the change in accrued expenses is driven by the reduction in interest payable related to the Term Loan Agreement, at LIBO + 600 bps, paid monthly, compared to the 10.5% Senior Notes, paid semiannually.

Investing

Cash provided by investing activities during the six-month period ended September 30, 2017 of $149.9 million reflects a $160.2 million increase compared to cash used in investing activities of $10.3 million in the six-month period ended September 30, 2016. The increase is primarily related to the acquisition of TOKIN, net of cash received, of $167.1 million in positive cash flow in the six-month period ended September 30, 2017 compared to no acquisitions in the six-month period ended September 30, 2016. Additionally, we had proceeds from sale of assets of $0.6 million in the six-month period ended September 30, 2017 and no proceeds from the sale of assets in the six-month period ended September 30, 2016.

Finally, during the six-month period ended September 30, 2017, we made capital expenditures of $17.8 million primarily related to expanding capacity at our manufacturing facilities in Mexico, Italy, China, Thailand and Japan, as well as information technology projects in Simpsonville, South Carolina.

In comparison, during the six-month period ended September 30, 2016, we made capital expenditures of $10.3 million, primarily related to expanding capacity at our manufacturing facilities in Portugal, China and Mexico, as well as information technology and ERP software upgrade projects in Simpsonville, South Carolina.

47

Financing

Cash used in financing activities during the six-month period ended September 30, 2017 of $47.7 million reflects a $45.2 million change from cash used in financing activities of $2.5 million in the six-month period ended September 30, 2016.    During the six-month period ended September 30, 2017, we used $353.0 million to repay the remaining outstanding balance of our 10.5% Senior Notes, $33.9 million to repay the remaining outstanding balance of the revolving line of credit, and received $329.7 million in proceeds from the Term Loan Credit Agreement, net of discount, bank issuance costs and other indirect issuance costs. Additionally, we made one quarterly payment on the Term Loan Credit Agreement of $4.3 million, and received proceeds on an interest free loan from the Portuguese Government of $0.3 million. Finally, proceeds from the exercise of stock warrants, dividends, and exercise of stock options generated $8.8 million, $0.6 million, and $4.1 million in cash, respectively.

In comparison, during the six-month period ended September 30, 2016, we used $1.9 million to retire $2.0 million face value of our 10.5% Senior Notes and also used $0.6 million for the purchase of treasury stock related to shares withheld to pay taxes due upon the vesting of restricted stock.

Commitments

With the exception of the items noted below, our commitments have not materially changed from those disclosed in the Company’s 2017 Annual Report as updated by our quarterly report for the quarter ended June 30, 2017. Due to an increase in anti-trust fines and settlements in the quarter ended September 30, 2017, an update to our contractual obligations is as follows (amounts in thousands):

			Payment Due by Period
Contractual obligations	Total		Year 1 (1)		Years 2 - 3		Years 4 - 5		More than 5 years
Anti-trust fines and settlements	$	81,634	$	45,537	$	24,749	$	10,336	$	1,012

_________________

⁽¹⁾ This amount includes the total of approximately $29.1 million included in the line item “Accrued expenses” on the Condensed Consolidated Balance Sheets as of September 30, 2017, however the timing of the payment is to be determined.

Non-U.S. Generally Accepted Accounting Principles Financial Measures

To complement our Condensed Consolidated Statements of Operations and Cash Flows, we use non-U.S. GAAP financial measures of Adjusted gross margin, Adjusted operating income (loss), Adjusted net income (loss) and Adjusted EBITDA.  Management believes that Adjusted gross margin, Adjusted operating income (loss), Adjusted net income (loss) and Adjusted EBITDA are complements to U.S. GAAP amounts and such measures are useful to investors. The presentation of these non-U.S. GAAP measures is not meant to be considered in isolation or as an alternative to net income as an indicator of our performance, or as an alternative to cash flows from operating activities as a measure of liquidity.

Adjusted gross margin represents net sales less cost of sales excluding adjustments which are outlined in the quantitative reconciliation provided above. We use Adjusted gross margin to facilitate our analysis and understanding of our business operations by excluding the items outlined in the quantitative reconciliation provided above which might otherwise make comparisons of our ongoing business with prior periods more difficult and obscure trends in ongoing operations. The Company believes that Adjusted gross margin is useful to investors because it provides a supplemental way to understand the underlying operating performance of the Company. Adjusted gross margin should not be considered as an alternative to gross margin or any other performance measure derived in accordance with U.S. GAAP.

Adjusted operating income (loss) represents operating income (loss), excluding adjustments which are outlined in the quantitative reconciliation provided above. We use Adjusted operating income (loss) to facilitate our analysis and understanding of our business operations by excluding the items outlined in the quantitative reconciliation provided above which might otherwise make comparisons of our ongoing business with prior periods more difficult and obscure trends in ongoing operations. The Company believes that Adjusted operating income (loss) is useful to investors to provide a supplemental way to understand our underlying operating performance and monitor and understand changes in our ability to generate income from ongoing business operations. Adjusted operating income (loss) should not be considered as an alternative to operating income or any other performance measure derived in accordance with U.S. GAAP.

Adjusted net income (loss) represents net income (loss), excluding adjustments which are more specifically outlined in the quantitative reconciliation provided above. We use Adjusted net income (loss) to evaluate our operating performance by excluding the items outlined in the quantitative reconciliation provided above which might otherwise make comparisons of our ongoing business with prior periods more difficult and obscure trends in ongoing operations. The Company believes that Adjusted net income (loss) is useful to investors because it provides a supplemental way to understand our underlying operating performance and allows investors to monitor and understand changes in our ability to generate income from ongoing business operations. Adjusted net income (loss) should not be considered as an alternative to net income (loss), operating income (loss) or any other performance measures derived in accordance with U.S. GAAP.

Adjusted EBITDA represents net income (loss) before interest expense, net, income tax expense (benefit), and depreciation and amortization expense, excluding adjustments which are outlined in the quantitative reconciliation provided above. We present Adjusted EBITDA as a supplemental measure of our performance and ability to service debt. We also present Adjusted EBITDA because we believe this measure is frequently used by securities analysts, investors and other

50

interested parties in the evaluation of companies in our industry. Adjusted EBITDA is also used as a measure to determine incentive compensation.

We believe Adjusted EBITDA is an appropriate supplemental measure of debt service capacity because cash expenditures on interest are, by definition, available to pay interest, and tax expense is inversely correlated to interest expense because tax expense goes down as deductible interest expense goes up; and depreciation and amortization are non-cash charges. The other items excluded from Adjusted EBITDA are excluded in order to better reflect our continuing operations.

In evaluating Adjusted EBITDA from continuing operations, you should be aware that in the future we may incur expenses similar to the adjustments noted above. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these types of adjustments. Adjusted EBITDA is not a measurement of our financial performance under U.S. GAAP and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with U.S. GAAP or as an alternative to cash flow from operating activities as a measure of our liquidity. 

Our Adjusted EBITDA measure has limitations as an analytical tool, and should not be considered in isolation or as a substitute for analysis of our results as reported under U.S. GAAP. Some of these limitations are:

• it does not reflect our cash expenditures, future requirements for capital expenditures or contractual commitments;

• it does not reflect changes in, or cash requirements for, our working capital needs;

• it does not reflect the significant interest expense or the cash requirements necessary to service interest or principal payments on our debt;

• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and our Adjusted EBITDA measure does not reflect any cash requirements for such replacements;

• it is not adjusted for all non-cash income or expense items that are reflected in our statements of cash flows;

• it does not reflect the impact of earnings or charges resulting from matters we consider not to be indicative of our ongoing operations;

• it does not reflect limitations on or costs related to transferring earnings from our subsidiaries to us; and

• other companies in our industry may calculate this measure differently than we do, limiting its usefulness as a comparative measure.

Because of these limitations, Adjusted EBITDA should not be considered as a measure of discretionary cash available to us to invest in the growth of our business or as a measure of cash that will be available to us to meet our obligations. You should compensate for these limitations by relying primarily on our U.S. GAAP results and using Adjusted EBITDA as supplementary information. 

Off-Balance Sheet Arrangements

Other than operating lease commitments, we are not a party to any material off-balance sheet financing arrangements that have, or are reasonably likely to have, a current or future material effect on our financial condition, revenues, expenses, results of operations, liquidity, capital expenditures or capital resources.

Impact of Recently Issued Accounting Standards

See Note 1, “Recently Issued Accounting Pronouncements," in the Notes to Consolidated Condensed Financial Statements for a discussion of recent accounting pronouncements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Foreign Currency Exchange Rate Risk

Given our international operations and sales, we are exposed to movements in foreign exchange rates. Of these, the most significant are currently the Euro, Japanese Yen and the Mexican Peso. A portion of our sales to our customers and operating costs in Europe are denominated in Euro creating an exposure to foreign currency exchange rates. Also, a portion of our costs in our operations in Mexico are denominated in Mexican Pesos, creating an exposure to foreign currency exchange rates. Additionally, some of our non-U.S. subsidiaries make sales denominated in U.S. dollars which expose them to foreign currency transaction gains and losses. Historically, in order to minimize our exposure, we periodically entered into forward foreign exchange contracts in which the future cash flows were hedged against the U.S. dollar (see Note 14, “Derivatives” to the consolidated financial statements). Finally, upon the TOKIN acquisition, a portion of our costs in our operations in Asia are denominated in Thai Baht, Chinese Yuan, Taiwan Dollars and Japanese Yen, creating an additional exposure to foreign currency exchange rates.

51

To evaluate the impact of foreign currency exchange rate changes on net income (loss), we used the following assumptions: All exchange rates change in the same direction at the same time, relative to the U.S dollar, and we included the TOKIN acquisition. Under these assumptions, an increase or decrease of 10 percent in foreign currency exchange rates would result in an estimated annual change in net income (loss) of $28.4 million and ($30.3) million, respectively.

Commodity Price Risk

As a result of our tantalum vertical integration efforts which began in fiscal year 2012, we have reduced our exposure to price volatility and supply uncertainty in the tantalum supply chain. A majority of our tantalum needs are now met through our direct sourcing of conflict free tantalum ore or tantalum scrap reclaim, which is then processed into the intermediate product potassium heptafluorotantalate (commonly known as K-salt) at our own facility in Mexico, before final processing into tantalum powder at KEMET Blue Powder Corporation. Price increases for tantalum ore, or for the remaining tantalum powder that we source from third parties, could impact our financial performance as we may be unable to pass all such price increases on to our customers.

Silver and aluminum have generally been available in sufficient quantities, and we believe there are a sufficient number of suppliers from which we can purchase our requirements. An increase in the price of silver and aluminum that we are unable to pass on to our customers, however, could have an adverse effect on our profitability.

To evaluate the impact of price changes in precious metals on net income (loss) we used the following assumptions: the selling prices of our products would not be impacted, all the precious metals change in the same direction at the same time, we do not have commitment contracts in place, and we included the TOKIN acquisition. Under these assumptions, a 10 percent increase or decrease in the cost of precious metals would result in approximately $10.8 million of increase or decrease to our annual net income (loss). We believe this risk is partially mitigated through our vertical integration efforts.

Other than the items noted above, there have been no material changes regarding the Company’s market risk position from the information included in the Company’s 2017 Annual Report. 

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of September 30, 2017, an evaluation of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) was performed under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and Chief Financial Officer.  Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in its reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that information required to be disclosed by the Company in the reports the Company files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There has been no change in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) of the Exchange Act) during the quarter ended September 30, 2017 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. 

In the first quarter of 2017, the Company acquired TOKIN (see Note 2, “Acquisitions”). As of the date of this Quarterly Report, we are in the process of further integrating the acquired operations into our overall internal controls over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Financial Statement Presentation

Basis of Financial Statement Presentation

The condensed consolidated financial statements contained herein are unaudited and have been prepared from the books and records of KEMET Corporation and its subsidiaries (“KEMET” or the “Company”). In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods. The condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q, and therefore, do not include all information and footnotes necessary for a complete presentation of financial position, results of operations, and cash flows in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). Although the Company believes the disclosures are adequate to make the information presented not misleading, it is suggested that these condensed consolidated financial statements be read in conjunction with the audited financial statements and notes thereto included in the Company’s Form 10-K for the fiscal year ended March 31, 2017 (the “Company’s 2017 Annual Report”).

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. In consolidation, all significant intercompany amounts and transactions have been eliminated.  Certain prior year amounts have been reclassified to conform to current year presentation.  Net sales and operating results for the quarter and six-month periods endedSeptember 30, 2017 are not necessarily indicative of the results to be expected for the full year.

The Company’s significant accounting policies are presented in the Company’s 2017 Annual Report.

Use of Estimates and Assumptions

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, assumptions, and judgments based on historical data and other assumptions that management believes are reasonable.  These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. In addition, they affect the reported amounts of revenues and expenses during the reporting period.

The Company’s judgments are based on management’s assessment as to the effect certain estimates, assumptions, or future trends or events may have on the financial condition and results of operations reported in the unaudited condensed consolidated financial statements. It is important that readers of these unaudited financial statements understand that actual results could differ from these estimates, assumptions, and judgments.

Recently Issued Accounting Pronouncements

New Accounting Standards Adopted/Issued

In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-12, Targeted Improvements to Accounting for Hedging Activities. The update amends and simplifies existing guidance in order to allow companies to more accurately present the economic effects of risk management activities in the financial statements. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this guidance on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The update requires employers to 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 income statement separately from the service cost component and outside a subtotal of Operating income. The Company states the other components of net benefit cost within Other (income) expense, net, on its Condensed Consolidated Statements of Operations. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The update requires retrospective application to all periods presented. The Company adopted this guidance in the first quarter of fiscal year 2018; the adoption of this guidance had an immaterial impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other. The update eliminates the requirement to calculate the implied fair value of goodwill to measure the amount of impairment loss, if any, under the second step of the current goodwill impairment test. Under the update, the goodwill impairment loss would be measured as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The effective date of this update is for annual reporting periods beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this guidance on the Company’s consolidated financial statements, however the adoption of this guidance is not expected to have a significant effect on the Company’s consolidated financial position, results of operations, or cash flows.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory. The update requires entities to recognize the income tax consequences of many intercompany asset transfers at the transaction date. The seller and buyer will immediately recognize the current and deferred income tax consequences of an intercompany transfer of an asset other than inventory.  The tax consequences were previously deferred. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The update requires modified retrospective transition method which is a cumulative effect adjustment to retained earnings as of the beginning of the first effective reporting period. The Company adopted this guidance as of April 1, 2017 and recorded a cumulative effect adjustment to retained earnings of $203,000.

In August 2016, the FASB issued ASU No. 2016-15,Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update clarifies how cash receipts and cash payments in certain transactions are presented and classified in the statement of cash flows. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The update requires retrospective application to all periods presented but may be applied prospectively if retrospective application is impracticable. The Company is currently evaluating the impact of the adoption of this guidance on the Company’s consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases. The ASU requires lessees to recognize a right-of-use asset and a lease liability for virtually all of their leases (other than short-term leases). The guidance is to be applied using a modified retrospective approach at the beginning of the earliest comparative period in the financial statements. This ASU is effective for fiscal years and interim periods within those years beginning after December 15, 2018. Early application is permitted. The Company is currently in the process of assessing the impact the adoption of this guidance will have on the Company’s consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which supersedes existing accounting standards for revenue recognition and creates a single framework. The new guidance requires either a retrospective or a modified retrospective approach at adoption. Additional updates to Topic 606 issued by the FASB in 2015 and 2016 include the following:

• ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which defers the effective date of the new guidance such that the new provisions will now be required for fiscal years, and interim periods within those years, beginning after December 15, 2017 (ASU No. 2015-14 is effective for the Company’s fiscal year that begins on April 1, 2018 and interim periods within that fiscal year).

• ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations, which clarifies the implementation guidance on principal versus agent considerations (reporting revenue gross versus net).

• ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarifies the implementation guidance on identifying performance obligations and classifying licensing arrangements.

• ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which clarifies the implementation guidance in a number of other areas.

• ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers.

The effective date of this guidance is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted, but not before the Company’s fiscal year that began on April 1, 2017 (the original effective date of the ASU). The Company plans to adopt the requirements of the new standard in the first quarter of fiscal year 2019.

The Company has completed the assessment phase, applied the principles of the new standard using the five step method to material customer contracts, and held discussions with key stakeholders and management. The Company is currently finalizing changes to accounting policies and internal controls over financial reporting. Key changes in the ASU that could potentially impact the Company’s revenue recognition include certain customer tooling contracts primarily within the original equipment manufacturers (“OEM”) channel and the deferral of incremental costs to fulfill a contract. The Company is currently finalizing the impact of the ASU on the consolidated results of operations, financial position, cash flows and financial statement disclosures.

There are currently no other accounting standards that have been issued that will have a significant impact on the Company’s financial position, results of operations or cash flows upon adoption.

Fair Value Measurement

The Company utilizes three levels of inputs to measure the fair value of (a) nonfinancial assets and liabilities that are recognized or disclosed at fair value in the Company’s consolidated financial statements on a recurring basis (at least annually) and (b) all financial assets and liabilities. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.

The first two inputs are considered observable and the last is considered unobservable. The levels of inputs are as follows:

• Level 1—Quoted prices in active markets for identical assets or liabilities.

• Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices 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 the assets or liabilities.

• Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Assets and liabilities measured at fair value on a recurring basis as of September 30, 2017 and March 31, 2017 are as follows (amounts in thousands):

	Carrying Value September 30,			Fair Value September 30,			Fair Value Measurement Using								Carrying Value March 31,			Fair Value March 31,			Fair Value Measurement Using

⁽²⁾ The valuation approach used to calculate fair value was a discounted cash flow based on the borrowing rate for each respective debt facility.

⁽³⁾ See Note 8, “Investment in TOKIN”, for a description of the TOKIN option, which was canceled on April 19, 2017 pursuant to the terms of the TOKIN Purchase Agreement.  The value of the option depended on the enterprise value of TOKIN and its forecasted EBITDA over the duration of the option. The option was valued using option pricing methods in a Monte Carlo simulation.

Warrant

On September 11, 2017, K Equity sold the remaining portion of the Platinum Warrant to UBS Securities LLC (the “Underwriter”), in connection with the offering of 8,416,814 shares of the Company’s common stock, at a public offering price of $21.57 per share. The Company filed a registration statement on Form S-3 to register the offer and resale by K Equity of the shares. The Company did not receive any of the proceeds from the sale of the shares in the Offering, but received approximately $8.8 million from the Underwriter in connection with the cash exercise of the Platinum Warrant for all 8,416,814 shares underlying the Platinum Warrant at an exercise price of $1.05 per share.

As of September 30, 2017, K Equity does not have any outstanding warrants for shares of the Company’s common stock.

Revenue Recognition

The Company ships products to customers based upon firm orders and revenue is recognized when the sales process is complete. This occurs when products are shipped to the customer in accordance with the terms of an agreement of sale, there is a fixed or determinable selling price, title and risk of loss have been transferred and collectability is reasonably assured. Based on product availability, customer requirements and customer consent, the Company may ship products earlier than the initial planned ship date. Shipping and handling costs are included in cost of sales.

A portion of sales is related to products designed to meet customer specific requirements. These products typically have stricter tolerances making them useful to the specific customer requesting the product and to customers with similar or less stringent requirements. The Company recognizes revenue when title to the products transfers to the customer.

A portion of sales is made to distributors under agreements allowing certain rights of return and price protection on unsold merchandise held by distributors. The Company’s distributor policy includes inventory price protection and “ship-from-stock and debit” (“SFSD”) programs common in the industry.

KEMET’s SFSD program provides authorized distributors with the flexibility to meet marketplace prices by allowing them, upon a pre-approved case-by-case basis, to adjust their purchased inventory cost to correspond with current market demand. Requests for SFSD adjustments are considered on an individual basis, require a pre-approved cost adjustment quote from their local KEMET sales representative and apply only to a specific customer, part, specified special price amount, specified quantity, and are only valid for a specific period of time. To estimate potential SFSD adjustments corresponding with current period sales, KEMET records a sales reserve based on historical SFSD credits, distributor inventory levels, and certain accounting assumptions, all of which are reviewed quarterly.

Most of the Company’s distributors have the right to return to KEMET a certain portion of the purchased inventory, which, in general, does not exceed 6% of their purchases from the previous fiscal quarter. KEMET estimates future returns based on historical return patterns and records a corresponding allowance on the Condensed Consolidated Balance Sheets. The Company also offers volume based rebates on a case-by-case basis to certain customers in each of the Company’s sales channels.

The establishment of sales allowances is recognized as a component of the line item “Net sales” on the Condensed Consolidated Statements of Operations, while the associated reserves are included in the line item “Accounts receivable, net” on the Condensed Consolidated Balance Sheets. Estimates used in determining sales allowances are subject to various factors. This includes, but is not limited to, changes in economic conditions, pricing changes, product demand, inventory levels in the supply chain, the effects of technological change, and other variables that might result in changes to the Company’s estimates.

The Company provides a limited warranty to customers that the Company’s products meet certain specifications. The warranty period is generally limited to one year, and the Company’s liability under the warranty is generally limited to a replacement of the product or refund of the purchase price of the product. Warranty costs as a percentage of net sales were less than 1.0% for the quarters and six-month periods endedSeptember 30, 2017 and 2016. The Company recognizes warranty costs when they are both probable and reasonably estimable.

Acquisitions [Abstract]

Business Combination Disclosure [Text Block]

Acquisitions

Sale of Electromagnetic Business and Acquisition of Remaining Interest in TOKIN

Between February 1, 2013 and April 19, 2017, KEMET, through its wholly-owned subsidiary, KEMET Electronics Corporation (“KEC”), held a 34% economic interest in TOKIN Corporation (“TOKIN”) pursuant to a Stock Purchase Agreement (the “Stock Purchase Agreement”) by and among KEC, TOKIN and NEC Corporation (“NEC”), as calculated based on the number of common shares held by KEC, directly and indirectly, in proportion to the aggregate number of common and preferred shares of TOKIN outstanding as of such date. TOKIN was established in Japan in 1938 and is engaged in production and distribution of tantalum capacitors, transmitting communication devices, magnetic devices, piezoelectric devices and sensors. TOKIN has six manufacturing locations throughout Asia and was previously operating as a joint venture with NEC.

On April 14, 2017, TOKIN closed on the sale of its electro-mechanical devices (“EMD”) business to NTJ Holdings 1 Ltd. (“NTJ”), a special purpose entity that is owned by funds managed or operated by Japan Industrial Partners, Inc. (“JIP”), pursuant to a master sale and purchase agreement (the “EMD Master Sale and Purchase Agreement”) previously entered into between TOKIN, NTJ and JIP (“Sale of EMD”). The initial selling price for EMD was JPY 48.2 billion, or approximately $431.0 million, using the March 31, 2017 exchange rate of 111.823 Japanese Yen to 1.00 U.S. Dollar, and is subject to certain working capital adjustments pursuant to the EMD Master Sale and Purchase Agreement. At the closing of the Sale of EMD, TOKIN used a portion of the sale proceeds to repay debt related to a shareholder loan from NEC. The TOKIN historical balance sheet was adjusted to reflect the removal of net assets sold and other items directly impacted by the Sale of EMD. Additionally, due to KEMET’s 34% equity interest in TOKIN held as of the closing, adjustments have been made to reflect KEMET’s accounting for the Sale of EMD in accordance with the equity method of accounting.

On April 19, 2017, pursuant to a stock purchase agreement (the “TOKIN Purchase Agreement”) dated February 23, 2017 between KEC and NEC, KEC completed its acquisition, subject to final purchase price adjustment, of the remaining 66% economic interest in TOKIN, and as a result, TOKIN is now a 100% owned indirect subsidiary of KEMET (the “TOKIN Acquisition”). Under the terms of the TOKIN Purchase Agreement, KEC paid NEC JPY 16.2 billion, or approximately $148.6 million (using the April 19, 2017 exchange rate of 109.007 Japanese Yen to 1.00 U.S. Dollar), for all of the outstanding shares of TOKIN it did not already own. The preliminary purchase price was comprised of JPY 6.0 billion, or approximately $55.0 million (using the April 19, 2017 exchange rate of 109.007 Japanese Yen to 1.00 U.S. Dollar) plus JPY 10.2 billion, or approximately $93.6 million, which represented one-half of the estimated excess net cash proceeds (“Excess Cash”) from the sale of TOKIN’s EMD business. The acquisition price was subject to working capital adjustments pursuant to the EMD Master Sale and Purchase Agreement, as a result the acquisition price was increased by JPY 0.3 billion, or approximately $3.0 million (using the September 30, 2017 exchange rate of 112.502 Japanese Yen to 1.00 U.S. Dollar) in the second quarter of fiscal year 2018.

The Company believes the acquisition of TOKIN will expand KEMET’s geographic presence, combining KEMET’s presence in the western hemisphere and TOKIN’s excellent position in Asia to enhance customer reach and create an entrance into Japan for KEMET. The Company believes TOKIN’s product portfolio is a strong complement to KEMET’s existing product portfolio. KEMET believes the combination creates a leader in the combined polymer and tantalum capacitors market. The acquisition also enhances KEMET’s product diversification with entry into Electro-Magnetic Compatible components ("EMC") as well as sensors and actuators. With the increased scale, the Company anticipates optimizing costs through competitive raw materials sourcing and maximizing operating efficiencies. Consistent with expectations, the acquisition has been accretive to earnings with improvement in Net income, Adjusted EBITDA and cash flow. TOKIN’s tantalum capacitor business is included within KEMET’s Solid Capacitors reportable segment and the remainder of TOKIN’s business formed a new reportable segment for KEMET, Electro-magnetic, Sensors & Actuators (“MSA”).

The following table shows the preliminary components of the acquisition price; the excess cash value may change upon finalization of working capital adjustments for the Sale of EMD (amounts in thousands):

Upfront cash consideration (1)	$	148,614
Acquisition payable (2)	3,144
Indemnity asset  (3)	8,500
Less: Put option (4)	(9,900		)
Net consideration transferred	$	150,358

_________________

⁽¹⁾ The upfront cash payment is comprised of JPY 6.0 billion plus one half of Excess Cash in an amount of approximately JPY 10.2 billion, approximately $55.0 million and $93.6 million, respectively.

⁽²⁾ Current estimate of the additional amount due to NEC Corporation upon the settlement of the adjusted purchase price for the EMD sale.

⁽³⁾ Pursuant to the Stock Purchase Agreement between KEMET and NEC, NEC was required to indemnify TOKIN and/or KEC for any breaches by TOKIN or NEC of certain representations, warranties and covenants in the Stock Purchase Agreement. NEC’s aggregate liability for indemnification claims was limited to $25.0 million. Prior to the acquisition, KEMET's equity method investment balance included an $8.5 million indemnification asset pursuant to this indemnification arrangement. In connection with the TOKIN Acquisition, NEC was released from its indemnification obligations to KEMET without an exchange of consideration; as such, this amount of released obligation is included as purchase consideration by KEMET.

⁽⁴⁾ Pursuant to the option agreement, dated as of March 12, 2012, by and among NEC and KEMET (the “Option Agreement”), from April 1, 2015 through May 31, 2018, NEC had the right to require KEC to purchase all outstanding capital stock of TOKIN (the “Put Option”). The fair value of the Put Option of $9.9 million was reflected as a liability on KEMET’s balance sheet prior to KEMET’s acquisition of the remaining 66% economic interest in TOKIN. The Put Option was canceled, pursuant to the terms of the TOKIN Purchase Agreement with no exchange of consideration between NEC and KEMET. Accordingly, the fair value of the Put Option reduces the amount of consideration paid to acquire NEC’s equity in TOKIN.

In accordance with ASC 805, KEMET’s previously held 34% equity interest in TOKIN and the assets acquired and the liabilities assumed have been measured at their fair values based on various preliminary estimates. The preliminary acquisition-date fair value of KEMET’s previously held 34% equity interest in TOKIN is approximately $207.8 million.

The following table presents the preliminary allocations of the aggregate purchase price based on the estimated fair values of the assets and liabilities (amounts in thousands):

	Fair Value
Cash	$	315,743
Accounts Receivable	79,295
Inventory	35,310
Other current assets	20,899
Property, Plant and equipment	159,597
Intangible assets (1)	35,452
Equity method investments	12,795
Other assets	8,533
Current portion of long term debt	(3,225		)
Accounts payable	(81,642		)
Accrued expenses	(46,276		)
Other non-current obligations	(103,486		)
Deferred income taxes (2)	(10,372		)
Total net assets acquired	$	422,623

_________________

⁽¹⁾ Includes trade name for $8.1 million and products and relationships of $25.2 million. TOKIN’s technology, products, and relationships were valued as a grouped, composite intangible asset due to the Company’s products being dependent on the existing technology, which enabled a product portfolio that customers found appealing in selecting and designing electronic components for purchase. The trade names were valued based on the relief from royalty method and and have indefinite remaining useful lives. The products and relationships were valued on the excess earnings method and are amortized over 10 years.

⁽²⁾ Amount revised in the second quarter of fiscal year 2018; however, the deferred tax value is still preliminary.

There were $0.6 million of acquisition-related costs, which were all recognized as an expense in the line item “Selling, general and administrative expenses” on the Condensed Consolidated Statements of Operations.

The above allocation of purchase price has been prepared based on preliminary estimates; the final amounts recorded may differ materially from the information presented herein. These estimates are subject to change pending further review of the acquired business. The following components of the initial valuation are still preliminary: deferred income taxes, accounts receivable reserves, inventory obsolescence, equity method investments, products and relationships, property plant and equipment for some locations, and management continues to reassess the bargain gain in accordance with ASC 805. In the quarter ended September 30, 2017, the acquisition payable was reduced to $3.1 million due to an update to the Excess Cash calculation and the value of the deferred income tax liability was increased $0.7 million due to additional detail received from the foreign subsidiaries, which changed the categorization and breakouts of deferred tax assets and liabilities, along with their corresponding valuation allowances. A change in the fair value of assets acquired or liabilities assumed in the merger from those preliminary valuations presented above would result in a corresponding change in the amount of bargain purchase gain that resulted from the merger in a business combination when the fair value of net assets acquired exceeds the sum of consideration transferred and the fair value of the acquirer’s previously held interest in the acquiree. The gain is recognized immediately in earnings in accordance with U.S. GAAP.

The following table reflects the preliminary bargain purchase gain resulting from the TOKIN Acquisition (amounts in thousands):

Net consideration transferred	$	150,358
Preliminary fair value of KEMET’s previously held equity interest in TOKIN	207,823
Less: Preliminary fair value of net assets acquired	(422,623		)
Bargain purchase gain	$	(64,442	)

The gain is included in the line item “Acquisition gains” in the Condensed Consolidated Statements of Operations.

10.5% Senior Notes

On April 28, 2017, the Company repurchased and retired the full outstanding balance of $353.0 million of its 10.5% Senior Notes due May 1, 2018 (the “10.5% Senior Notes”). The Company had interest payable related to the 10.5% Senior Notes included in the line item “Accrued expenses” on its Condensed Consolidated balance sheets of zero and $15.4 million as of September 30, 2017 and March 31, 2017, respectively.

Term Loan Credit Agreement

On April 28, 2017, KEMET entered into a Term Loan Credit Agreement (the “Term Loan Credit Agreement”) by and among the Company, KEC (together with the Company, the “Borrowers”), Bank of America, N.A. as the Administrative Agent and Collateral Agent, Merrill Lynch, Pierce, Fenner & Smith Incorporated, as sole lead arranger and bookrunner and various other lenders thereto from time to time.

The Term Loan Credit Agreement provides for a $345 million term loan facility. In addition, the Borrowers may request incremental term loan commitments in an aggregate amount not to exceed $50 million (together with the initial $345 million term loan, the “Term Loans”). The proceeds were used, together with cash on hand, to fund the redemption of all of KEMET’s outstanding 10.5% Senior Notes, which were also called for redemption on April 28, 2017. The Term Loans were made with an original issue discount of 300 basis points. At the Company’s election, the Term Loans may be made as either Base Rate Term Loans or LIBO Rate Term Loans (each as defined in the Term Loan Credit Agreement). The applicable margin for term loans is 5.0% for Base Rate Term Loans and 6.0% for LIBO Rate Term Loans. All LIBO Rate Term Loans are subject to a pre-margin floor of 1.00%. The Term Loan Credit Agreement contains customary covenants and events of default.

The Company also entered into the Term Loan Security Agreement dated as of April 28, 2017 (the “Security Agreement”), by and among the Company, KEC and certain other subsidiaries of the Company and Bank of America, N.A., as collateral agent, pursuant to which the Company’s obligations under the Term Loan Credit Agreement are secured by a pledge of 65% of the outstanding voting stock of certain first-tier subsidiaries organized in Italy, Japan, Mexico and Singapore, and a second lien pledge on the collateral securing KEMET’s revolving credit facility. The obligations of the Company under the Term Loan Credit Agreement are guaranteed by certain of its subsidiaries, including KRC Trade Corporation, KEMET Services Corporation, KEMET Blue Powder Corporation and The Forest Electric Company. The Term Loans mature April 28, 2024, and may be extended in accordance with the Term Loan Credit Agreement. The Company may prepay loans under the Term Loan Credit Agreement at any time, subject to certain notice requirements and certain prepayment premiums during the first two years. The Company made an initial payment of 1.25% of the aggregate principal amount of the initial $345 million term loan, or $4.3 million, during the month of September. These payments will be made quarterly per the Term Loan Credit Agreement.

The Company currently pays interest on the Term Loan Security Agreement on a monthly basis due to favorable LIBO rates, and as such had no interest payable related to the Term Loan Security Agreement included in the line item “Accrued expenses” on its Condensed Consolidated balance sheets as of September 30, 2017 and March 31, 2017.

Revolving Line of Credit

In connection with the closing of the new Term Loan Credit Agreement, KEC also entered into Amendment No. 9 to Loan and Security Agreement, Waiver and Consent, dated as of April 28, 2017, by and among KEC, the other borrowers named therein, the financial institutions party thereto as lenders and Bank of America, N.A., as agent for the lenders (the “Loan Amendment”). The Loan Amendment increases the facility amount to $75.0 million and provides KEC with lower applicable interest rate margins and the ability to complete the refinancing. As part of the overall refinancing, KEC also repaid all amounts outstanding under the Loan Amendment.

As of September 30, 2017, there were no borrowings under the revolving line of credit, and the Company’s available borrowing capacity, which is based on factors including outstanding eligible accounts receivable, inventory and equipment collateral, under the Loan and Security Agreement was $71.7 million.

Other Debt

In January 2017, KEMET’s wholly-owned subsidiary, KEMET Electronics Portugal, S.A., received the first part of an interest free loan from the Portuguese Government in the amount of EUR 2.2 million (or $2.5 million) to be used for fixed asset purchases. In July 2017 KEMET Electronics Portugal, S.A. received the second part of the loan in the amount of EUR 277 thousand (or $325 thousand). The loan has a total term of eight years ending February 1, 2025. The loan will be repaid through semi-annual payments beginning on August 1, 2019. The first payment will be in the amount of EUR 185 thousand (or $211 thousand) beginning on August 1, 2019 and the remaining payments will be in the amount of EUR 210 thousand (or $248 thousand). Since the debt is non-interest bearing, we have recorded a debt discount in the amount of EUR 0.5 million (or $0.6 million) with an offsetting reduction to fixed assets. This discount will be amortized over the life of the loan through interest expense. If certain conditions are met, such as increased headcount, increased revenue and increased gross value added, a portion of the loan could be forgiven during fiscal year 2020.

In September 2017, TOKIN received a short term borrowing pursuant to an overdraft agreement with the 77 Bank of Miyagi, Japan, in the amount of 350 million yen (or $3.1 million), at an interest rate of 0.53% (JBA TIBOR + 40 basis points). The loan is due September 2018, and the loan agreement automatically renews if both parties choose not to terminate or modify it.

Impairment Charges

The Company did not record any significant write downs and/or disposals of long-lived assets in the quarter ended September 30, 2017.

In the quarter ended September 30, 2016 KEMET recorded a write down of long-lived assets of $6.3 million due to the following two actions.

On August 31, 2016, KEC made the decision to shut-down operations of its wholly-owned subsidiary, KEMET Foil Manufacturing, LLC (“KFM”). Operations at KFM’s Knoxville, Tennessee plant ceased as of October 31, 2016. KFM supplied formed foil to the Company’s Film and Electrolytic segment (“Film and Electrolytic”), as well as to certain third party customers. The Company anticipates that Film and Electrolytic will achieve raw material cost savings by purchasing its formed foil from suppliers that have the advantage of lower utility costs. During the second fiscal quarter ending September 30, 2016, Film and Electrolytic recorded impairment charges totaling $4.1 million comprised of $3.0 million for the write down of property plant and equipment and $1.1 million for the write down of intangible assets. The impairment charges are recorded on the Condensed Consolidated Statements of Operations line item “Write down of long-lived assets”. In addition, the Company has accrued severance charges and restructuring costs described in Note 6, “Restructuring Charges.”

The Solid Capacitor segment (“Solid Capacitors”) initiated a plan to relocate its K-Salt operations from a leased facility to its existing Matamoros, Mexico facility. Impairment charges of approximately $2.1 million are recorded on the Condensed Consolidated Statements of Operations line item “Write down of long-lived assets”. In addition, the Company has accrued severance charges described in Note 6, “Restructuring Charges”.

Segment Reporting [Abstract]

Segment and Geographic Information

Segment and Geographic Information

The Company is organized into three segments: Solid Capacitors, Film and Electrolytics and Electro-magnetic, Sensors & Actuators (“MSA”).  In prior periods we reported two reportable segments, Solid Capacitors and Film and Electrolytics. However, effective beginning the quarter ended June 30, 2017 and in connection with the TOKIN acquisition, TOKIN’s tantalum capacitor business is included within KEMET’s Solid Capacitors reportable segment and the remainder of TOKIN’s business became a new reportable segment (MSA). Refer to Note 2, "Acquisitions," for additional information on MSA.

The segments are responsible for their respective manufacturing sites as well as their respective research and development efforts. The Company does not allocate corporate indirect selling, general and administrative (“SG&A”) or shared Research and development (“R&D”) expenses to the segments.  Results for the first quarter of fiscal year 2018 have been reclassified to conform to the current period presentation where certain regional SG&A amounts have been allocated to certain segments, and also a portion of the allocation within the segments was allocated to costs of goods sold. These adjustments are reflected in the six-month results included below.

Solid Capacitors

Solid Capacitors operates in ten manufacturing sites in the United States, Mexico and Asia, and operates innovation centers in the United States and Japan. Solid Capacitors primarily produces tantalum, aluminum polymer, and ceramic capacitors which are sold globally.  Solid Capacitors also produces tantalum powder used in the production of tantalum capacitors.

Film and Electrolytic

Film and Electrolytic operates in nine manufacturing sites throughout Europe and Asia. Film and Electrolytic primarily produces film, paper, and electrolytic capacitors which are sold globally. In addition, this segment has product innovation centers in Portugal, Italy and Sweden.

MSA

MSA operates in four manufacturing sites throughout Asia. MSA primarily produces electro magnetically compatible materials and components, Piezo materials and actuators and various types of sensors which are sold globally. In addition, this segment has a product innovation center in Sendai, Japan.

The following table reflects each segment’s net sales, operating income (loss), depreciation and amortization expenses and sales by region for the quarters and six-month periods endedSeptember 30, 2017 and 2016 (amounts in thousands):

Defined Benefit Pension and Other Postretirement Benefit Plans

The Company sponsors six defined benefit pension plans in Europe, one plan in Singapore, two plans in Mexico, and, with the completion of the TOKIN acquisition in April 2017, one plan in Japan.  In addition, the Company maintains two frozen post-retirement benefit plans in the United States: health care and life insurance benefits for certain retired United States employees who reached retirement age while working for the Company. The health care plan is contributory, with participants’ contributions adjusted annually. The life insurance plan is non-contributory. Finally, the Company sponsors one other post-retirement benefit plan in Japan.  Costs recognized for benefit plans are recorded using estimated amounts which may change as actual costs for the fiscal year are determined.

Stock-based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-based Compensation

Stock-Based Compensation

As of September 30, 2017, the KEMET Corporation Omnibus Incentive Plan (the “Incentive Plan”), which amended and restated the KEMET Corporation 2014 Amendment and Restatement of the KEMET Corporation 2011 Omnibus Equity Incentive Plan, approved by the Company’s stockholders on August 2, 2017, is the only plan the Company has to issue equity based awards to executives and key employees. Upon adoption of the Incentive Plan, no further awards were permitted to be granted under the Company’s prior plans, including the 1992 Key Employee Stock Option Plan, the 1995 Executive Stock Option Plan, and the 2004 Long-Term Equity Incentive Plan (collectively, the “Prior Plans”).

The Incentive Plan authorized the grant of up to 12.2 million shares of the Company’s Common Stock, comprised of 11.4 million shares under the Incentive Plan and 0.8 million shares remaining from the Prior Plans and authorizes the Company to provide equity-based compensation in the form of:

• stock options, including incentive stock options, entitling the optionee to favorable tax treatment under Section 422 of the Code;

• stock appreciation rights;

• restricted stock and restricted stock units (“RSUs”);

• other share-based awards; and,

• performance awards.

Except as described below, options issued under these plans vest within two to three years and expire ten years from the grant date. Restricted stock and RSUs issued under these plans vest over three to four years, except for RSUs granted to members of the Board of Directors, which vest within one year, and performance-based RSUs, which vest over a one-year period following achievement of two-year performance targets. The Company grants RSUs to members of the Board of Directors, the Chief Executive Officer and key management. Once vested and settled, RSUs are converted into restricted stock. For members of the Board of Directors and senior personnel, such restricted stock cannot be sold until 90 days after termination of service with the Company, or until the individual achieves the targeted ownership under the Company’s stock ownership guidelines, and only to the extent that such ownership level exceeds the target. Compensation expense is recognized over the respective vesting periods. 

Historically, the Board of Directors of the Company has approved annual Long Term Incentive Plans (“LTIP”) which cover two year periods and are primarily based upon the achievement of an Adjusted EBITDA range for the two-year period. At the time of the award, the individual plans entitle the participants to receive cash or RSUs, or a combination of both as determined by the Company’s Board of Directors. The 2015/2016 LTIP, 2016/2017 LTIP, 2017/2018 LTIP, and 2018/2019 LTIP also awarded RSUs which vest over the course of three years from the anniversary of the establishment of the plan and are not subject to a performance metric. The Company assesses the likelihood of meeting the Adjusted EBITDA financial metric on a quarterly basis and adjusts compensation expense to match expectations. Any related liability is reflected in the line item “Accrued expenses” on the Condensed Consolidated Balance Sheets and any restricted stock unit commitment is reflected in the line item “Additional paid-in capital” on the Condensed Consolidated Balance Sheets.

On May 18, 2017, the Company granted RSUs under the 2018/2019 LTIP with a grant date fair value of $13.41 that vest as follows (amounts in thousands):

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

Derivatives

In fiscal year 2015, the Company began using certain derivative instruments (i.e., foreign exchange contracts) to reduce exposure to the volatility of foreign currencies impacting revenues and the costs of its products.

Certain operating expenses at the Company’s Mexican facilities are paid in Mexican Pesos. In order to hedge a portion of these forecasted cash flows, the Company purchases foreign exchange contracts, with terms generally less than twelve months, to buy Mexican Pesos for periods and amounts consistent with underlying cash flow exposures. These contracts are designated as cash flow hedges at inception and monitored for effectiveness on a routine basis. There were $64.8 million and $49.1 million in Peso contracts (notional value) outstanding at September 30, 2017 and March 31, 2017, respectively.

The Company formally documents all relationships between hedging instruments and hedged items, as well as risk management objectives and strategies for undertaking various hedge transactions.

The Company records and presents the fair values of all of its derivative assets and liabilities in the Consolidated Balance Sheets on a net basis, since they are subject to master netting agreements. However, if the Company were to offset and record the asset and liability balances of its forward foreign currency exchange contracts on a gross basis, the amounts presented in the Consolidated Balance Sheets would be adjusted from the current net presentation to the gross amounts as detailed in the following table.

The balance sheet classifications and fair value of derivative instruments as of September 30, 2017 and March 31, 2017 are as follows (amounts in thousands):

	Fair Value of Derivative Instruments (1)
	September 30, 2017						March 31, 2017
Balance Sheet Presentation	As Presented (1)		Offset		Gross		As Presented (1)		Offset			Gross

_________________

⁽¹⁾ Fair Value measured using Level 2 inputs by adjusting the market spot rate by forward points, based on the date of the contract. The spot rates and forward points used are based on an average rate from an actively traded market.

The impact on the Consolidated Statement of Operations for the quarters and six-month periods endedSeptember 30, 2017 and 2016 are as follows (amounts in thousands):

Statement Caption	Quarter Ended September 30, 2017		Quarter Ended September 30, 2016			Six-Month Period Ended September 30, 2017		Six-Month Period Ended September 30, 2016

Operating income (loss)	$	1,104	$	(1,140	)	$	45	$	(2,893	)

Unrealized gains and losses associated with the change in value of these financial instruments are recorded in AOCI. Changes in the derivatives’ fair values are deferred and recorded as a component of AOCI until the underlying transaction is settled and recorded to the income statement. When the hedged item affects income, gains or losses are reclassified from AOCI to the Consolidated Statement of Operations as Cost of sales for foreign exchange contracts to purchase such foreign currency. Any ineffectiveness, if material, in the Company’s hedging relationships is recognized immediately as a loss, within the same income statement accounts as described above; to date, there has been no ineffectiveness. Changes in derivative balances impact the line items “Prepaid and other assets” and “Accrued expenses” on the Consolidated Balance Sheets and Statements of Cash Flows.

Risks and Uncertainties [Abstract]

Concentrations of Risks

Concentrations of Risks

The Company sells to customers globally and, as the Company generally does not require collateral from its customers, on a monthly basis the Company evaluates customer account balances in order to assess the Company’s financial risks of collection.  One customer, TTI, Inc., an electronics distributor, accounted for over 10% of the Company’s net sales in the quarters and six-month periods endedSeptember 30, 2017 and 2016.  There were no accounts receivable balances from any customer exceeding 10% of gross accounts receivable as of September 30, 2017 and March 31, 2017.

Electronics distributors are an important channel in the electronics industry and accounted for 39% and 46% of the Company’s net sales in the six-month periods ended September 30, 2017 and 2016, respectively.  As a result of the Company’s concentration of sales to electronics distributors, the Company may experience fluctuations in the Company’s operating results as electronics distributors experience fluctuations in end-market demand and/or adjust their inventory stocking levels. 

Legal Update

In July 2013, TOKIN was named as one of eight defendants in two purported U.S. class action antitrust lawsuits (In Re: Lithium Ion Batteries Antitrust Litigation, 13-MD-02420-YGR, United States District Court, Northern District of California) (the “Battery Class Action Suits”) regarding the sale of lithium ion batteries brought on behalf of direct product purchasers and indirect product purchasers. On April 12, 2017, motions to approve class certification on behalf of the direct product purchasers and indirect product purchasers plaintiffs were denied by the Court; plaintiffs were given leave to amend. On August 17, 2017, TOKIN reached a preliminary settlement by which, in consideration of the release of TOKIN and its subsidiaries from claims asserted in the Battery Class Action Suits, TOKIN agreed to pay $4.95 million to the settlement class of direct product purchasers. The settlement is subject to execution of a definitive agreement and court approval. Pursuant to the terms of the preliminary settlement, the settlement amount is payable within 21 days after preliminary court approval.

Beginning in March 2014, TOKIN and certain of its subsidiaries received inquiries, requests for information and other communications from government authorities in China, the United States, the European Commission, Japan, South Korea, Taiwan, Singapore and Brazil concerning alleged anti-competitive activities within the capacitor industry. 

On September 2, 2015, the United States Department of Justice announced a plea agreement with TOKIN in which TOKIN agreed to plead guilty to a one-count felony charge of unreasonable restraint of interstate and foreign trade and commerce in violation of Section 1 of the Sherman Act, and to pay a criminal fine of $13.8 million. The plea agreement was approved by the United States District Court, Northern District of California, on January 21, 2016. The fine is payable over five years in six installments of $2.3 million each, plus accrued interest. The first and second payments were made in February 2016 and January 2017, respectively, while the next payment is due in January 2018.

On December 9, 2015, the Taiwan Fair Trade Commission (“TFTC”) publicly announced that TOKIN would be fined 1,218.2 million New Taiwan dollars (“NTD”) (approximately U.S. $40.2 million) for violations of the Taiwan Fair Trade Act. Subsequently, the TFTC has reduced the fine to NTD609.1 million (approximately U.S. $20.1 million). In February 2016, TOKIN commenced an administrative suit in Taiwan, challenging the validity of the amount of the fine.

On March 29, 2016, the Japan Fair Trade Commission published an order by which TOKIN was fined ¥127.2 million (approximately U.S. $1.1 million) for violation of the Japanese Antimonopoly Act. Payment of the fine was made on October 31, 2016.

On July 15, 2016, TOKIN entered into definitive settlement agreements in two antitrust suits filed with the United States District Court, Northern District of California as In re: Capacitors Antitrust Litigation, No. 3:14-cv-03264-JD (the “Capacitor Class Action Suits”). Pursuant to the terms of the settlement, in consideration of the release of TOKIN and its subsidiaries (including TOKIN America, Inc.) from claims asserted in the Capacitor Class Action Suits, TOKIN will pay an aggregate $37.3 million to a settlement class of direct purchasers of capacitors and a settlement class of indirect purchasers of capacitors. Each of the respective class payments is payable in five installments, two of which were paid on or before respective due dates of July 29, 2016 and 2017, the next two of which are due each year thereafter on the anniversary of the initial payment, and the final payment is due by December 31, 2019.

On July 27, 2016, Brazil’s Administrative Council for Economic Defense approved a cease and desist agreement with TOKIN in which TOKIN made a financial contribution of Brazilian Real 0.6 million (approximately U.S. $0.2 million) to Brazil’s Fund for Defense of Diffuse Rights.

The remaining governmental investigations are continuing at various stages. As of September 30, 2017, TOKIN’s accrual for antitrust and civil litigation claims totaled $81.6 million which is stated in the following line items, “Account payable” ($10.1 million), “Accrued expenses” ($35.4 million) and “Other non-current obligations” ($36.1 million) on the Condensed Consolidated Balance Sheets. This amount includes the best estimate of losses which may result from the ongoing antitrust investigations, civil litigation and claims. However, the actual outcomes could differ from what has been accrued. Additionally, under the terms of the TOKIN Purchase Agreement, TOKIN will be responsible for defending all suits, paying all expenses and satisfying all judgments to the extent arising out of or related the capacitor antitrust investigations and related litigation described above.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Use of Estimates and Assumptions

Use of Estimates and Assumptions

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, assumptions, and judgments based on historical data and other assumptions that management believes are reasonable.  These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. In addition, they affect the reported amounts of revenues and expenses during the reporting period.

The Company’s judgments are based on management’s assessment as to the effect certain estimates, assumptions, or future trends or events may have on the financial condition and results of operations reported in the unaudited condensed consolidated financial statements. It is important that readers of these unaudited financial statements understand that actual results could differ from these estimates, assumptions, and judgments.

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements

New Accounting Standards Adopted/Issued

In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-12, Targeted Improvements to Accounting for Hedging Activities. The update amends and simplifies existing guidance in order to allow companies to more accurately present the economic effects of risk management activities in the financial statements. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this guidance on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The update requires employers to 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 income statement separately from the service cost component and outside a subtotal of Operating income. The Company states the other components of net benefit cost within Other (income) expense, net, on its Condensed Consolidated Statements of Operations. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The update requires retrospective application to all periods presented. The Company adopted this guidance in the first quarter of fiscal year 2018; the adoption of this guidance had an immaterial impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other. The update eliminates the requirement to calculate the implied fair value of goodwill to measure the amount of impairment loss, if any, under the second step of the current goodwill impairment test. Under the update, the goodwill impairment loss would be measured as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The effective date of this update is for annual reporting periods beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this guidance on the Company’s consolidated financial statements, however the adoption of this guidance is not expected to have a significant effect on the Company’s consolidated financial position, results of operations, or cash flows.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory. The update requires entities to recognize the income tax consequences of many intercompany asset transfers at the transaction date. The seller and buyer will immediately recognize the current and deferred income tax consequences of an intercompany transfer of an asset other than inventory.  The tax consequences were previously deferred. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The update requires modified retrospective transition method which is a cumulative effect adjustment to retained earnings as of the beginning of the first effective reporting period. The Company adopted this guidance as of April 1, 2017 and recorded a cumulative effect adjustment to retained earnings of $203,000.

In August 2016, the FASB issued ASU No. 2016-15,Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update clarifies how cash receipts and cash payments in certain transactions are presented and classified in the statement of cash flows. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The update requires retrospective application to all periods presented but may be applied prospectively if retrospective application is impracticable. The Company is currently evaluating the impact of the adoption of this guidance on the Company’s consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases. The ASU requires lessees to recognize a right-of-use asset and a lease liability for virtually all of their leases (other than short-term leases). The guidance is to be applied using a modified retrospective approach at the beginning of the earliest comparative period in the financial statements. This ASU is effective for fiscal years and interim periods within those years beginning after December 15, 2018. Early application is permitted. The Company is currently in the process of assessing the impact the adoption of this guidance will have on the Company’s consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which supersedes existing accounting standards for revenue recognition and creates a single framework. The new guidance requires either a retrospective or a modified retrospective approach at adoption. Additional updates to Topic 606 issued by the FASB in 2015 and 2016 include the following:

• ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which defers the effective date of the new guidance such that the new provisions will now be required for fiscal years, and interim periods within those years, beginning after December 15, 2017 (ASU No. 2015-14 is effective for the Company’s fiscal year that begins on April 1, 2018 and interim periods within that fiscal year).

• ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations, which clarifies the implementation guidance on principal versus agent considerations (reporting revenue gross versus net).

• ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarifies the implementation guidance on identifying performance obligations and classifying licensing arrangements.

• ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which clarifies the implementation guidance in a number of other areas.

• ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers.

The effective date of this guidance is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted, but not before the Company’s fiscal year that began on April 1, 2017 (the original effective date of the ASU). The Company plans to adopt the requirements of the new standard in the first quarter of fiscal year 2019.

The Company has completed the assessment phase, applied the principles of the new standard using the five step method to material customer contracts, and held discussions with key stakeholders and management. The Company is currently finalizing changes to accounting policies and internal controls over financial reporting. Key changes in the ASU that could potentially impact the Company’s revenue recognition include certain customer tooling contracts primarily within the original equipment manufacturers (“OEM”) channel and the deferral of incremental costs to fulfill a contract. The Company is currently finalizing the impact of the ASU on the consolidated results of operations, financial position, cash flows and financial statement disclosures.

There are currently no other accounting standards that have been issued that will have a significant impact on the Company’s financial position, results of operations or cash flows upon adoption.

Fair Value Measurement

Fair Value Measurement

The Company utilizes three levels of inputs to measure the fair value of (a) nonfinancial assets and liabilities that are recognized or disclosed at fair value in the Company’s consolidated financial statements on a recurring basis (at least annually) and (b) all financial assets and liabilities. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.

The first two inputs are considered observable and the last is considered unobservable. The levels of inputs are as follows:

• Level 1—Quoted prices in active markets for identical assets or liabilities.

• Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices 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 the assets or liabilities.

• Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Warrant

Warrant

On September 11, 2017, K Equity sold the remaining portion of the Platinum Warrant to UBS Securities LLC (the “Underwriter”), in connection with the offering of 8,416,814 shares of the Company’s common stock, at a public offering price of $21.57 per share. The Company filed a registration statement on Form S-3 to register the offer and resale by K Equity of the shares. The Company did not receive any of the proceeds from the sale of the shares in the Offering, but received approximately $8.8 million from the Underwriter in connection with the cash exercise of the Platinum Warrant for all 8,416,814 shares underlying the Platinum Warrant at an exercise price of $1.05 per share.

As of September 30, 2017, K Equity does not have any outstanding warrants for shares of the Company’s common stock.

Revenue Recognition

Revenue Recognition

The Company ships products to customers based upon firm orders and revenue is recognized when the sales process is complete. This occurs when products are shipped to the customer in accordance with the terms of an agreement of sale, there is a fixed or determinable selling price, title and risk of loss have been transferred and collectability is reasonably assured. Based on product availability, customer requirements and customer consent, the Company may ship products earlier than the initial planned ship date. Shipping and handling costs are included in cost of sales.

A portion of sales is related to products designed to meet customer specific requirements. These products typically have stricter tolerances making them useful to the specific customer requesting the product and to customers with similar or less stringent requirements. The Company recognizes revenue when title to the products transfers to the customer.

A portion of sales is made to distributors under agreements allowing certain rights of return and price protection on unsold merchandise held by distributors. The Company’s distributor policy includes inventory price protection and “ship-from-stock and debit” (“SFSD”) programs common in the industry.

KEMET’s SFSD program provides authorized distributors with the flexibility to meet marketplace prices by allowing them, upon a pre-approved case-by-case basis, to adjust their purchased inventory cost to correspond with current market demand. Requests for SFSD adjustments are considered on an individual basis, require a pre-approved cost adjustment quote from their local KEMET sales representative and apply only to a specific customer, part, specified special price amount, specified quantity, and are only valid for a specific period of time. To estimate potential SFSD adjustments corresponding with current period sales, KEMET records a sales reserve based on historical SFSD credits, distributor inventory levels, and certain accounting assumptions, all of which are reviewed quarterly.

Most of the Company’s distributors have the right to return to KEMET a certain portion of the purchased inventory, which, in general, does not exceed 6% of their purchases from the previous fiscal quarter. KEMET estimates future returns based on historical return patterns and records a corresponding allowance on the Condensed Consolidated Balance Sheets. The Company also offers volume based rebates on a case-by-case basis to certain customers in each of the Company’s sales channels.

The establishment of sales allowances is recognized as a component of the line item “Net sales” on the Condensed Consolidated Statements of Operations, while the associated reserves are included in the line item “Accounts receivable, net” on the Condensed Consolidated Balance Sheets. Estimates used in determining sales allowances are subject to various factors. This includes, but is not limited to, changes in economic conditions, pricing changes, product demand, inventory levels in the supply chain, the effects of technological change, and other variables that might result in changes to the Company’s estimates.

The Company provides a limited warranty to customers that the Company’s products meet certain specifications. The warranty period is generally limited to one year, and the Company’s liability under the warranty is generally limited to a replacement of the product or refund of the purchase price of the product. Warranty costs as a percentage of net sales were less than 1.0% for the quarters and six-month periods endedSeptember 30, 2017 and 2016. The Company recognizes warranty costs when they are both probable and reasonably estimable.

⁽²⁾ Current estimate of the additional amount due to NEC Corporation upon the settlement of the adjusted purchase price for the EMD sale.

⁽³⁾ Pursuant to the Stock Purchase Agreement between KEMET and NEC, NEC was required to indemnify TOKIN and/or KEC for any breaches by TOKIN or NEC of certain representations, warranties and covenants in the Stock Purchase Agreement. NEC’s aggregate liability for indemnification claims was limited to $25.0 million. Prior to the acquisition, KEMET's equity method investment balance included an $8.5 million indemnification asset pursuant to this indemnification arrangement. In connection with the TOKIN Acquisition, NEC was released from its indemnification obligations to KEMET without an exchange of consideration; as such, this amount of released obligation is included as purchase consideration by KEMET.

⁽⁴⁾ Pursuant to the option agreement, dated as of March 12, 2012, by and among NEC and KEMET (the “Option Agreement”), from April 1, 2015 through May 31, 2018, NEC had the right to require KEC to purchase all outstanding capital stock of TOKIN (the “Put Option”). The fair value of the Put Option of $9.9 million was reflected as a liability on KEMET’s balance sheet prior to KEMET’s acquisition of the remaining 66% economic interest in TOKIN. The Put Option was canceled, pursuant to the terms of the TOKIN Purchase Agreement with no exchange of consideration between NEC and KEMET. Accordingly, the fair value of the Put Option reduces the amount of consideration paid to acquire NEC’s equity in TOKIN.
