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, 2015 (the “Company’s 2015 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 ended June 30, 2015 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 2015 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 April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The ASU specifies that debt issuance costs related to a note shall be reported in the balance sheet as a direct reduction from the face amount of the note. The ASU is effective for the Company for interim and annual periods beginning after April 1, 2016. Early adoption is permitted. The ASU will require the Company to reclassify its capitalized debt issuance costs currently recorded as assets on the consolidated condensed balance sheets. The ASU will have no effect on the Company's results of operations or liquidity. In August 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU")2014-15, Presentation of Financial Statements-Going Concern. The new guidance is effective for the Company's fiscal year that begins on April 1, 2017 and interim periods within that fiscal year and requires management to assess if there is substantial doubt about an entity’s ability to continue as a going concern for each annual and interim period. If conditions or events give rise to substantial doubt, disclosures are required. This new guidance is not expected to have a material impact on the Company's Consolidated Financial Statements. In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU")2014-09, Revenue from Contracts with Customers, which supersedes existing accounting standards for revenue recognition and creates a single framework. The new guidance is effective for the Company's fiscal year that begins on April 1, 2018 and interim periods within that fiscal year and requires either a retrospective or a modified retrospective approach to adoption. The Company is currently evaluating the potential impact on its Consolidated Financial Statements and related disclosures, as well as the available transition methods. Early adoption is permitted, but not before Company's fiscal year that begins on April 1, 2017 (the original effective date of the ASU). We are currently in the process of assessing the impact the adoption of this guidance will have on our consolidated financial statements. 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. Restricted Cash A bank guarantee in the amount of €1.5 million ( $1.7 million ) was issued by a European bank on behalf of the Company in August 2006 in conjunction with the establishment of a Value-Added Tax (“VAT”) registration in The Netherlands. Accordingly, a deposit was placed with the European bank for €1.7 million ( $1.8 million ). While the deposit is in KEMET’s name, and KEMET receives all interest earned by this deposit, the deposit is pledged to the European bank, and the bank can use the funds if a valid claim against the bank guarantee is made. The bank guarantee will remain valid until it is discharged by the beneficiary. 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 June 30, 2015 and March 31, 2015 are as follows (amounts in thousands): Carrying Value June 30, Fair Value June 30, Fair Value Measurement Using Carrying Value March 31, Fair Value March 31, Fair Value Measurement Using 2015 2015 Level 1 Level 2 (2) Level 3 2015 2015 Level 1 Level 2 (2) Level 3 Assets (Liabilities): Money markets (1) $ 738 $ 738 $ 738 $ — $ — $ 738 $ 738 $ 738 $ — $ — Total debt (396,261 ) (390,240 ) (356,775 ) (33,465 ) — (391,371 ) (391,283 ) (362,988 ) (28,295 ) — NEC TOKIN options, net (3) (23,500 ) (23,500 ) — — (23,500 ) 5,700 5,700 — — 5,700 ___________________ (1) Included in the line item “Cash and cash equivalents” on the Condensed Consolidated Balance Sheets. (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 6 , Investment in NEC TOKIN, for a description of the NEC TOKIN options. The value of the options is interrelated and depends on the enterprise value of NEC TOKIN Corporation and its forecasted EBITDA over the duration of the instruments. The options have been valued using option pricing methods in a Monte Carlo simulation. The table below summarizes NEC TOKIN option valuation activity using significant unobservable inputs (Level 3) (amounts in thousands): March 31, 2015 $ 5,700 Change in value of NEC TOKIN options (29,200 ) June 30, 2015 $ (23,500 ) Inventories Inventories are stated at the lower of cost or market. The components of inventories are as follows (amounts in thousands): June 30, 2015 March 31, 2015 Raw materials and supplies $ 90,308 $ 83,372 Work in process 53,657 52,759 Finished goods 56,505 53,211 200,470 189,342 Inventory reserves (16,986 ) (17,499 ) $ 183,484 $ 171,843 Warrant As of June 30, 2015 and March 31, 2015 , 8.4 million shares were subject to the warrant (which expires June 30, 2019) held by K Equity, LLC. 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. 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 ended June 30, 2015 and 2014 . The Company recognizes warranty costs when they are both probable and reasonably estimable.

Investment in NEC TOKIN

Equity Method Investments and Joint Ventures [Abstract]
Investment in NEC TOKIN	Investment in NEC TOKIN On March 12, 2012, KEC, a wholly owned subsidiary of the Company, entered into a Stock Purchase Agreement (the "Stock Purchase Agreement") with NEC TOKIN Corporation ("NEC TOKIN"), a manufacturer of tantalum capacitors, electro-magnetic, electro-mechanical and access devices, to acquire 51% of the common stock of NEC TOKIN (which represented a 34% economic interest, as calculated based on the number of common shares held by KEC, directly and indirectly, in proportion to the aggregate number of outstanding common and preferred shares of NEC TOKIN as of such date) (the "Initial Purchase") from NEC Corporation ("NEC") of Japan. The transaction closed on February 1, 2013, at which time KEC paid a purchase price of $50.0 million for new shares of common stock of NEC TOKIN (the “Initial Closing”). The Company accounts for its investment in NEC TOKIN using the equity method for a non-consolidated variable interest entity since KEC does not have the power to direct significant activities of NEC TOKIN. The Company believes that the NEC TOKIN preferred stock represents in-substance common stock of NEC TOKIN and, as a result, its method of calculating KEC’s economic basis in NEC TOKIN is the appropriate basis on which to recognize its share of the earnings or loss of NEC TOKIN. In connection with KEC’s execution of the Stock Purchase Agreement, KEC entered into a Stockholders’ Agreement (the “Stockholders’ Agreement”) with NEC TOKIN and NEC, which provides for restrictions on transfers of NEC TOKIN’s capital stock, certain tag-along and first refusal rights on transfer, restrictions on NEC’s ability to convert the preferred stock of NEC TOKIN held by it, certain management services to be provided to NEC TOKIN by KEC (or an affiliate of KEC) and certain board representation rights. KEC holds four of seven NEC TOKIN director positions. However, NEC has significant board rights. Concurrent with execution of the Stock Purchase Agreement and the Stockholders’ Agreement, KEC entered into an Option Agreement (the “Option Agreement”) with NEC, which was amended on August 29, 2014, whereby KEC had the right to purchase additional shares of NEC TOKIN common stock from NEC TOKIN for a purchase price of $50.0 million resulting in an economic interest of approximately 49% while maintaining ownership of 51% of NEC TOKIN’s common stock (the “First Call Option”) by providing notice of the First Call Option between the Initial Closing and April 30, 2015. Upon providing such First Call Option notice, but not before April 1, 2015, KEC could also have exercised a second option to purchase all outstanding capital stock of NEC TOKIN from its stockholders, primarily NEC, for a purchase price based on the greater of six times LTM EBITDA (as defined in the Option Agreement) less the previous payments and certain other adjustments, or the outstanding amount of NEC TOKIN’s debt obligation to NEC (the “Second Call Option”) by providing notice of the Second Call Option by May 31, 2018. The First and Second Call Options expired on April 30, 2015 without being exercised. From April 1, 2015 through May 31, 2018, NEC may require KEC to purchase all outstanding capital stock of NEC TOKIN from its stockholders, primarily NEC (the "Put Option"), provided that KEC's payment of the Put Option price is permitted under the 10.5% Senior Notes and Loan and Security Agreement. However, in the event that KEC issues new debt securities principally to refinance its outstanding 10.5% senior notes due 2018 and its currently outstanding credit agreement, including amounts to pay related fees and expenses and to use for general corporate purposes (“Refinancing Notes”), prior to NEC’s delivery of its notification of exercise of the Put Option, then the earliest date NEC may exercise the Put Option is automatically extended to the day immediately following the final scheduled maturity date of such Refinancing Notes, or in the event such Refinancing Notes are redeemed in full prior to such final scheduled maturity date, then on the day immediately following the date of such full redemption, but in any event beginning no later than November 1, 2019. If not previously exercised, the Put Option will expire on October 31, 2023. The purchase price for the Put Option will be based on the greater of six times LTM EBITDA less previous payments and certain other adjustments, or the outstanding amount of NEC TOKIN’s debt obligation to NEC as of the date the Put Option is exercised. The purchase price for the Put Option is reduced by the amount of NEC TOKIN’s debt obligation to NEC which KEC will assume. The determination of the purchase price could be modified in the event there is a disagreement between NEC and KEC under the Stockholders’ Agreement. The Company has marked these options to fair value and in the quarter ended June 30, 2015 recognized a $29.2 million loss, which was included on the line item “Other (income) expense, net” in the Condensed Consolidated Statement of Operations. The line item "Other non-current obligation" on the Condensed Consolidated Balance Sheets includes $23.5 million and “Other assets” includes $5.7 million as of June 30, 2015 and March 31, 2015 , respectively, related to the options. It changed to a liability position during the quarter ended June 30, 2015 due to expiration of the First and Second Call Options on April 30, 2015 without being exercised. KEC's total investment in NEC TOKIN including the net call derivative described above on February 1, 2013, the closing date of the acquisition, was $54.5 million which includes $50 million cash consideration plus approximately $4.5 million in transaction expenses (fees for legal, accounting, due diligence, investment banking and various other services necessary to complete the transactions). The Company has made an allocation of the aggregate purchase price, which was based upon estimates that the Company believes are reasonable. Summarized financial information for NEC TOKIN follows (amounts in thousands): June 30, March 31, Current assets $ 225,284 $ 223,495 Non-current assets 266,048 273,785 Current liabilities 141,405 143,523 Non-current liabilities 289,731 296,873 Quarters Ended June 30, 2015 2014 Sales $ 114,734 $ 122,408 Gross profit 24,668 26,678 Net income (loss) 5,255 (3,154 ) A reconciliation between NEC TOKIN's net income (loss) and KEMET's equity investment income (loss) follows (amounts in thousands): Quarters Ended June 30, 2015 2014 NEC TOKIN net income (loss) $ 5,255 $ (3,154 ) KEMET's economic interest % 34 % 34 % Equity income (loss) from NEC TOKIN before adjustments 1,787 (1,072 ) Adjustments: Amortization and depreciation (136 ) (603 ) Inventory valuation (66 ) — Equity income (loss) from NEC TOKIN $ 1,585 $ (1,675 ) A reconciliation between NEC TOKIN's net assets and KEMET's investment in NEC TOKIN balance follows (amounts in thousands): June 30, March 31, Investment in NEC TOKIN $ 45,668 $ 45,016 Purchase price accounting basis adjustment: Property, plant and equipment 3,293 3,334 Technology (10,317 ) (10,889 ) Long-term debt (2,440 ) (2,707 ) Goodwill (6,932 ) (7,082 ) Indemnity asset for legal investigation (8,500 ) (8,500 ) Inventory profit elimination 274 208 Other (579 ) (39 ) KEMET's 34% economic interest of NEC TOKIN's net assets $ 20,467 $ 19,341 The above basis differences (except Goodwill) are being amortized over the respective estimated life of the assets. As of June 30, 2015 , KEC’s maximum loss exposure as a result of its investments in NEC TOKIN is limited to the aggregate of the carrying value of the investment and any accounts receivable balance due from NEC TOKIN. For the quarters ended June 30, 2015 and 2014 , KEMET recorded sales of $4.9 million and $1.9 million , respectively, to NEC TOKIN and NEC TOKIN recorded sales of $1.5 million and $0.5 million , respectively, to KEMET. As of June 30, 2015 and March 31, 2015 , KEMET's accounts receivable from NEC TOKIN were $3.1 million and $3.3 million , respectively. KEMET's accounts payable to NEC TOKIN were $0.5 million and $0.8 million as of June 30, 2015 and March 31, 2015 , respectively. In accordance with the Stockholders’ Agreement, KEC entered into a management services agreement with NEC TOKIN to provide services for which KEC would be reimbursed. As of June 30, 2015 and March 31, 2015 , KEC’s receivable balance under this agreement was $0.6 million . Beginning in March 2014, NEC 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. The investigations are continuing at various stages. In addition, beginning in July 2014, NEC TOKIN and its subsidiary, NEC TOKIN America, Inc., have been named, along with more than 20 other capacitor manufacturers and subsidiaries, as defendants in purported antitrust class action suits by direct and indirect purchasers in the United States and Canada. As of March 31, 2015, NEC TOKIN has recorded an accrual for approximately $30.0 million based on its estimation of losses likely to result from certain of the investigations and civil litigation. Pursuant to the Stock Purchase Agreement, NEC is required to indemnify NEC TOKIN and/or KEC for any breaches by NEC TOKIN or NEC of certain representations, warranties and covenants in the Stock Purchase Agreement. NEC’s aggregate liability for indemnification claims is limited to $25.0 million . Accordingly, KEMET, under equity method accounting, has established an indemnity asset in the amount of $8.5 million (based upon our 34% economic interest in NEC TOKIN). However, pursuant to the Stock Purchase Agreement, claims arising out of fraud or criminal conduct are not limited by the $25.0 million indemnification cap, and for such claims the claimant retains all remedies available in equity or at law. As of June 30, 2015 , NEC TOKIN could not estimate the total losses which may result from the ongoing investigations and civil litigation because NEC TOKIN does not have sufficient information to be able to estimate the amount of all such losses. During the quarter ended June 30, 2015 , NEC TOKIN has not changed the estimated accrual.

Business Combination Disclosure [Text Block]	Acquisitions IntelliData On April 1, 2015, KEMET purchased 100% of the stock of IntelliData, Inc. "IntelliData", a Greenwood Village, Colorado-based developer of digital solutions supporting discovery, decision support, and the sales and marketing of electronic components. IntelliData has been a key vendor of KEMET for over 15 years and has provided critical software and support to allow the Company's sales team and customers to use real-time part number search and competitor cross references based on complex capacitor-specific specifications. The primary reason for the purchase of IntelliData was to gain more control over the direction of future iterations of the software and its functionality and to protect this critical link in the sales process from any potential unfavorable changes in IntelliData's business model in the future. The purchase price was $6.0 million plus an additional $0.1 million per a post-acquisition amendment for a total purchase price of $6.1 million , as amended. KEMET paid $3.0 million at closing, $0.1 million on June 3, 2015, and will pay the balance of $3.0 million on January 4, 2016 per the amended agreement. The Company preliminarily recorded goodwill of $4.7 million and amortizable intangibles of $1.8 million . The allocation of the purchase price to specific assets and liabilities was based on the relative fair value of all assets and liabilities. Factors contributing to the purchase price, which resulted in the goodwill, include the knowledge and expertise of the trained workforce as well as various trademarks. Pro forma results are not presented because the acquisition was not material to the consolidated financial statements. 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 $ 233 Accounts Receivable 10 Other current assets 6 Property, Plant and equipment 3 Goodwill 4,710 Intangible assets 1,820 Current liabilities (9 ) Deferred income taxes (648 ) Total net assets acquired $ 6,125 The allocation of the purchase price is preliminary as the Company is still evaluating the intangible assets and tax attributes of the transaction.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-based Compensation	Stock-based Compensation The Company’s stock-based compensation plans are broad-based, long-term retention programs intended to attract and retain talented employees and align stockholder and employee interests. At June 30, 2015 , the Company had four stock option plans that reserved shares of common stock for issuance to executives and key employees: the 1992 Key Employee Stock Option Plan, the 1995 Executive Stock Option Plan, the 2004 Long-Term Equity Incentive Plan (collectively, the “Prior Plans”) and the 2011 Omnibus Equity Incentive Plan (as amended by the 2014 Amendment and Restatement of the KEMET Corporation 2011 Omnibus Equity Incentive Plan) (the “2011 Incentive Plan”). Upon adoption and approval of the 2011 Incentive Plan, no further awards were permitted to be granted under the Company's prior plans. The 2011 Incentive Plan authorizes the Company to provide equity-based compensation in the form of: (1) stock options, including incentive stock options, entitling the optionee to favorable tax treatment under Section 422 of the Code; (2) stock appreciation rights; (3) restricted stock and restricted stock units; (4) other share-based awards; and (5) performance awards. Options issued under these plans vest within one to four years and expire ten years from the grant date. The Company grants restricted stock units to members of the Board of Directors, the Chief Executive Officer and key management. Once vested and settled, restricted stock units 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 target for the two-year period. At the time of the award, the individual plans entitle the participants to receive cash or restricted stock units, or a combination of both as determined by the Company’s Board of Directors. The 2013/2014 LTIP, 2014/2015 LTIP, 2015/2016 LTIP, and 2016/2017 LTIP also awarded restricted stock units 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.

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 ended June 30, 2015 and 2014 . There were no accounts receivable balances from any customer exceeding 10% of gross accounts receivable as of June 30, 2015 and March 31, 2015 . Electronics distributors are an important distribution channel in the electronics industry and accounted for 43% and 47% of the Company’s net sales in the three month periods ended June 30, 2015 and 2014 , 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 or adjust their inventory stocking levels.

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 April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The ASU specifies that debt issuance costs related to a note shall be reported in the balance sheet as a direct reduction from the face amount of the note. The ASU is effective for the Company for interim and annual periods beginning after April 1, 2016. Early adoption is permitted. The ASU will require the Company to reclassify its capitalized debt issuance costs currently recorded as assets on the consolidated condensed balance sheets. The ASU will have no effect on the Company's results of operations or liquidity. In August 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU")2014-15, Presentation of Financial Statements-Going Concern. The new guidance is effective for the Company's fiscal year that begins on April 1, 2017 and interim periods within that fiscal year and requires management to assess if there is substantial doubt about an entity’s ability to continue as a going concern for each annual and interim period. If conditions or events give rise to substantial doubt, disclosures are required. This new guidance is not expected to have a material impact on the Company's Consolidated Financial Statements. In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU")2014-09, Revenue from Contracts with Customers, which supersedes existing accounting standards for revenue recognition and creates a single framework. The new guidance is effective for the Company's fiscal year that begins on April 1, 2018 and interim periods within that fiscal year and requires either a retrospective or a modified retrospective approach to adoption. The Company is currently evaluating the potential impact on its Consolidated Financial Statements and related disclosures, as well as the available transition methods. Early adoption is permitted, but not before Company's fiscal year that begins on April 1, 2017 (the original effective date of the ASU). We are currently in the process of assessing the impact the adoption of this guidance will have on our consolidated financial statements. 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.
Restricted Cash	Restricted Cash A bank guarantee in the amount of €1.5 million ( $1.7 million ) was issued by a European bank on behalf of the Company in August 2006 in conjunction with the establishment of a Value-Added Tax (“VAT”) registration in The Netherlands. Accordingly, a deposit was placed with the European bank for €1.7 million ( $1.8 million ). While the deposit is in KEMET’s name, and KEMET receives all interest earned by this deposit, the deposit is pledged to the European bank, and the bank can use the funds if a valid claim against the bank guarantee is made. The bank guarantee will remain valid until it is discharged by the beneficiary.
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. Assets and liabilities measured at fair value on a recurring basis as of June 30, 2015 and March 31, 2015 are as follows (amounts in thousands): Carrying Value June 30, Fair Value June 30, Fair Value Measurement Using Carrying Value March 31, Fair Value March 31, Fair Value Measurement Using 2015 2015 Level 1 Level 2 (2) Level 3 2015 2015 Level 1 Level 2 (2) Level 3 Assets (Liabilities): Money markets (1) $ 738 $ 738 $ 738 $ — $ — $ 738 $ 738 $ 738 $ — $ — Total debt (396,261 ) (390,240 ) (356,775 ) (33,465 ) — (391,371 ) (391,283 ) (362,988 ) (28,295 ) — NEC TOKIN options, net (3) (23,500 ) (23,500 ) — — (23,500 ) 5,700 5,700 — — 5,700 ___________________ (1) Included in the line item “Cash and cash equivalents” on the Condensed Consolidated Balance Sheets. (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 6 , Investment in NEC TOKIN, for a description of the NEC TOKIN options. The value of the options is interrelated and depends on the enterprise value of NEC TOKIN Corporation and its forecasted EBITDA over the duration of the instruments. The options have been valued using option pricing methods in a Monte Carlo simulation. The table below summarizes NEC TOKIN option valuation activity using significant unobservable inputs (Level 3) (amounts in thousands): March 31, 2015 $ 5,700 Change in value of NEC TOKIN options (29,200 ) June 30, 2015 $ (23,500 )

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. 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 ended June 30, 2015 and 2014 . The Company recognizes warranty costs when they are both probable and reasonably estimable.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	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. The balance sheet classifications and fair value of derivative instruments as of June 30, 2015 are as follows (amounts in thousands): Fair Value of Derivative Instruments Asset Derivatives Liability Derivatives Balance Sheet Caption Fair Value (1) Balance Sheet Caption Fair Value (1) Foreign exchange contracts Prepaid and other assets $ — Accrued expenses $ 1,944 ______________________________________________________________________________ (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. Unrealized gains and losses associated with the change in value of these financial instruments are recorded in Accumulated other comprehensive income (loss) ("AOCI"). The pre-tax impact on AOCI related to the change in value of these financial instruments is as follows (amounts in thousands): Three Month Period Ended June 30, 2015 Beginning of fiscal year $ 1,003 Current fiscal year unrealized gain (loss) related to the change in value of the financial instruments (2,947 ) Plus unrealized gain (loss) in AOCI that were recognized in the current fiscal year — Net change in AOCI related to financial instruments (2,947 ) Balance at June 30, 2015 $ (1,944 ) 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 Net sales for foreign exchange contracts to sell euros, and as Cost of sales for foreign exchange contracts to purchase Mexican pesos and Japanese yen. 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.

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 $34.3 million in peso contracts (notional value) outstanding at June 30, 2015 . Certain expenditures at the Company's Mexican facilities are paid in Japanese yen. In order to hedge a portion of these forecasted cash flows, the Company purchases foreign exchange contracts, with terms generally less than six months, to buy Japanese yen 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 $9.1 million in yen contracts (notional value) outstanding at June 30, 2015 . Certain sales are made in euros. In order to hedge a portion of these forecasted cash flows, management purchases foreign exchange contracts, with terms generally less than six months, to sell euros for periods and amounts consistent with the related underlying cash flow exposures. These contracts are designated hedges at inception and monitored for effectiveness on a routine basis. There were $7.1 million in euro contracts (notional value) outstanding at June 30, 2015 .

The most recent annual goodwill impairment test was performed for all reporting units as of January 1, 2015. The Company also performs Step 1 of the goodwill impairment test on an interim basis upon the occurrence of events or substantive changes in circumstances that indicate that a reporting unit's carrying value may be less than its fair value. The Company completed an interim impairment test on goodwill and indefinite-lived intangible assets as of June 30, 2015, due to an indicator of possible impairment related to a significant decline in our stock price. Consistent with the policy described in the 2015 10-K, the Company performed Step 1 of the goodwill impairment test using a discounted cash flow analysis to estimate the fair value of the reporting unit. The Company also evaluated the indefinite-lived intangible assets, including trademarks with a carrying value of $7.2 million , associated with the reporting unit for impairment as of June 30, 2015. The Company concluded that goodwill and indefinite-lived assets were not impaired nor were they at risk of failing step one of the impairment test as the ratios of fair value of the assets to carrying value were 1.9:1 and 13.1:1 for goodwill and trademarks, respectively. A one percent increase or decrease in the discount rate used in the goodwill valuation would have resulted in changes in the fair value of $(13.2) million and $16.7 million , respectively, and a one percent increase or decrease in the discount rate used in the indefinite-lived assets valuation would have resulted in changes in the fair value of $(10.0) million and $12.6 million , respectively. Neither would have resulted in an impairment charge.
