Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | 1. General: AVX Corporation is a leading worldwide manufacturer, supplier and reseller of a broad line of electronic components and interconnect, sensing and control devices, and related products. The consolidated financial statements of AVX Corporation (“AVX” or “the Company”) include all accounts of the Company and its subsidiaries. All significant intercompany transactions and accounts have been eliminated. From January 1990 August 15, 1995, March 31, 2019, 72% Use of Estimates: The consolidated financial statements are prepared in accordance with generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported periods. We base our estimates and judgments on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not no not Cash Equivalents and Investments in Securities: We consider all highly liquid investments purchased with an original maturity of three 90 Our short-term and long-term investment securities are accounted for as held-to-maturity securities and are carried at amortized cost. We have the ability and intent to hold these investments until maturity. All income generated from the held-to-maturity securities investments are recorded as interest income. Inventories: We determine the cost of raw materials, work in process, and finished goods inventories by the first first Property and Equipment: Property and equipment are recorded at cost. Machinery and equipment are depreciated on the double-declining balance and straight-line methods. Buildings are depreciated on the straight-line method. The estimated useful lives used for computing depreciation are as follows: buildings and improvements – 10 31.5 3 10 $37,493, $50,813 $75,830 March 31, 2017, 2018 2019, We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of any such assets may not The cost of maintenance and repairs is charged to expense as incurred. Upon disposal or retirement, the cost and accumulated depreciation of assets are eliminated from the respective accounts. Any gain or loss is reflected in our results of operations. Goodwill and Acquired Intangible Assets: We test goodwill for impairment annually, or whenever conditions indicate that such impairment could exist. The carrying value of the reporting unit is evaluated in relation to the operating performance and estimated future discounted cash flows of the related reporting unit. If the sum of the discounted cash flows is less than the carrying value of the related assets, we recognize an impairment loss, measured as the amount by which the carrying value exceeds the fair value of the assets. The estimate of cash flow is based upon, among other things, certain assumptions about expected future operating performance, including assumptions in gross profit and the determination of the discount rate to be utilized. Our annual goodwill impairment analysis indicated that there was no March 31, 2017, 2018, 2019.

Two critical assumptions, discount rate and expected rate of return on plan assets, are important elements of plan expense and/or liability measurement. We evaluate these assumptions annually. The discount rate enables us to state expected future cash flows at a present value on the measurement date. To determine the discount rate, we apply the expected cash flows from each individual pension plan to specific yield curves at the plan’s measurement date and determine a level equivalent yield unique to each plan. A lower discount rate increases the present value of benefit obligations and increases pension expense. To determine the expected long-term rate of return on pension plan assets, we consider the current and expected asset allocations, as well as historical and expected returns on various categories of plan assets. Other assumptions involve demographic factors such as retirement, mortality, and turnover. These assumptions are evaluated annually and are updated to reflect our experience. Actual results in any given year will often differ from actuarial assumptions because of economic and other factors. In such cases, the differences between actual results and actuarial assumptions are amortized over future periods. Income Taxes: As part of the process of preparing our consolidated financial statements, we are required to estimate our tax assets and liabilities in each of the jurisdictions in which we operate. This process involves management estimating the actual current tax exposure together with assessing temporary differences resulting from different treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities that are included within our consolidated balance sheets. We assess the likelihood that our deferred tax assets will be recoverable based on all available evidence, both positive and negative. To the extent we believe that recovery is not not, We have recorded valuation allowances due to uncertainties related to our ability to realize some of our deferred tax assets, primarily consisting of certain net operating losses carried forward before they expire. The valuation allowance is based on our estimates of future taxable income over the periods that our deferred tax assets will be recoverable. We continue to evaluate countries where we have a valuation allowance on our deferred tax assets due to historical operating losses and when such positive evidence outweighs negative evidence we will release such valuation allowance as appropriate. We also record a provision for certain international, federal, and state tax contingencies based on the likelihood of obligation, when needed. In the normal course of business, we are subject to challenges from U.S. and non-U.S. tax authorities regarding the amount of taxes due. These challenges may may may We account for uncertainty in income taxes recognized in our financial statements. We recognize in our financial statements the impact of a tax position, if that position would “more likely than not” The provision for income tax expense for the fiscal year ended March 31, 2019 $61.4 $187.4 March 31, 2018.

Operating accounts are translated at an average rate of exchange for the respective accounting periods. Translation adjustments result from the process of translating foreign currency financial statements into U.S. dollars and are reported separately as a component of accumulated other comprehensive income (loss). Transaction gains and losses reflected in the functional currencies are reported in our results of operations at the time of the transaction. Derivative Financial Instruments: Derivative instruments are reported on the consolidated balance sheets at their fair values. The accounting for changes in fair value depends upon the purpose of the derivative instrument and whether it is designated and qualifies for hedge accounting. For instruments designated as accounting hedges, the effective portion of gains or losses is reported in other comprehensive income (loss) and is reclassified into the statement of operations in the same period during which the hedged transaction affects our results of operations. Any contracts that do not We use financial instruments such as forward exchange contracts to hedge a portion, but not 15 Revenue Recognition and Accounts Receivable: All products are built to specification and tested by AVX or our suppliers for adherence to such specification before shipment to customers. We ship products to customers based upon firm orders. Shipping and handling costs are treated as fulfillment costs and as such are included in cost of sales. The Company applies this accounting policy election consistently to its sales. We recognize revenue as performance obligations are satisfied, which is when the customer takes control of the products as they are shipped to or received by the customer in accordance with the terms of the agreement of sale. There are general product warranties within our contracts, as the Company warrants that products will function as expected in accordance with the specifications per the contract. These warranties cannot be purchased by the customer separately and accordingly these warranties are not Payment terms for the Company’s sales are generally less than 90 twelve 606 606” twelve not We evaluate gross versus net presentation on revenues from products purchased and resold in accordance with the revenue recognition criteria outlined in ASC 606. 606, The Company pays commissions to sales representatives on a per-sale basis and applies the practical expedient available within Accounting Standards Codification 340 340” The Company recognizes the estimated variable consideration to be received as revenue and records a related reduction to accounts receivable or as an accrued expense for the consideration not not no not 606, not Accounts Receivable We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. The allowance is determined through an analysis of the aging of accounts receivable and assessments of risk that are based on historical trends and an evaluation of the impact of current and projected economic conditions. We evaluate the past-due status of trade receivables based on contractual terms of sale. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may Returns Sales revenue and cost of sales reported in the statement of operations are reduced to reflect estimated returns. We record an estimated right of return liability for returns at the time of sale based on historical trends, current pricing and volume information, other market specific information, and input from sales, marketing, and other key management personnel. The liability accrued reflects the variable consideration not Distribution Programs A portion of our sales to independent electronic component distributor customers are subject to various distributor sales programs. We report provisions for distributor allowances in connection with such sales programs as a reduction in revenue and report distributor allowances on the balance sheet as either a reduction in accounts receivable or right-of-return liabilities. For the distribution programs described below, we do not Distributor Stock Rotation Program Stock rotation is a program whereby distributor customers are allowed to return for credit qualified inventory, semi-annually, equal to a certain percentage, primarily limited to 5% six Distributor Ship-from-Stock and Debit Program Ship-from-Stock and Debit (“ship and debit”) is a program designed to assist distributor customers in meeting competitive prices in the marketplace on sales to their end customers. Ship and debit programs require a request from the distributor for a pricing adjustment for a specific part for a sale to the distributor’s end customer from the distributor’s stock. The pricing adjustment is deemed variable consideration. Ship and debit authorizations may Special Incentive Programs We may Research, Development, and Engineering: Research, development, and engineering expenditures are expensed when incurred.

The amount of compensation cost is measured based on the grant-date fair value for the share-based payment issued. Our policy is to grant stock options with an exercise price equal to our stock price on the date of grant. Compensation cost is recognized over the vesting period of the award. We use the Black-Scholes-Merton option-pricing model to determine the fair value of stock options at the grant date. We use the closing fair market value of the Company’s common stock on the grant date to determine the fair value of restricted stock units (“RSU”) at the grant date.
