REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Participants and Administrator of the

AVX Nonqualified Supplemental Retirement Plan:

We have audited the accompanying statements of financial condition with fund information of the AVX Nonqualified Supplemental Retirement Plan (the Plan) as of December 31, 2010 and 2009, and the related statements of income and changes in plan equity with fund information for each of the three years in the period ended December 31, 2010. Our audits of the basic financial statements included the financial statement schedule listed in the index appearing under Schedule I. These financial statements and financial statement schedule are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Plan as of December 31, 2010 and 2009, and the results of its operations for each of the three years in the period ended December 31, 2010, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

AVX NONQUALIFIED SUPPLEMENTAL RETIREMENT PLAN

NOTES TO FINANCIAL STATEMENTS

1.	Description of Plan

The following brief description of the AVX Nonqualified Supplemental Retirement Plan (the “Plan”) is provided for general information purposes only. Participants should refer to the Plan document for more complete information.

General

The Plan was established August 1, 1994 to provide certain officers and highly compensated managers of AVX Corporation, (“AVX”) or (the "Company") with supplemental retirement benefits. Effective January 1, 2005, the AVX Corporation SERP Plan (the “SERP Plan”), that was established January 1, 1998, was merged into the Plan. All balances from the SERP Plan were transferred into the Plan. Any employee eligible to participate in the AVX Corporation Retirement Plan is eligible to participate in the SERP portion of the plan and any employee eligible to participate in the AVX Corporation Retirement plan whose annual compensation is in excess of $230,000, $245,000, and $245,000 for the plan years 2008, 2009 and 2010, respectively (as such limit is defined by the Internal Revenue Code) is eligible to participate in the Supplemental Retirement portion of the Plan. An employee who, in prior years, becomes an eligible participant in the Plan shall continue to be eligible to fully participate in the Plan regardless of whether such employee’s annual compensation falls below the annual compensation limit for the year. In December of 2007, the Plan was amended to comply with the final regulations under Internal Revenue Code Section 409A. These amendments were effective January 1, 2008. The Company is the Plan’s sponsor and Plan administrator. New York Life Trust Company (the “Trustee”) is the Plan’s trustee and record keeper.

In 2009, the Plan was amended and restated effective January 1, 2010. Among other changes to the Plan, the amendment eliminated the Supplemental Retirement portion of the Plan with the related eligibility criteria. In addition, the amended Plan provides that all employer contributions will be paid annually, and plan eligibility is based upon Company's Board of Directors discretion.

Deferred Compensation Contribution

The Plan is split into two parts. There is a SERP portion and a Supplemental Retirement portion. The SERP portion allows each participant to irrevocably elect to defer receipt of all or a portion of eligible compensation for that year prior to January l of each year. The Supplemental Retirement portion allows participants to defer an amount from 1% to 3% of eligible compensation (currently between $245,000 and $600,000). Eligible compensation for employee contributions to the supplemental portion is determined based on total compensation less any amount deferred under the SERP portion of the Plan.

Company Matching Contribution

The Company will match contributions equal to 100% of the first 3% of the amount that is deferred under the AVX Corporation Retirement Plan. After the maximum contribution limit has been reached under the AVX Corporation Retirement Plan, the Company will match contributions equal to 100% of the first 3% of the amount deferred that is related to eligible compensation (currently between $245,000 as indexed and $600,000) in the Plan. This match to the plan shall be invested in the AVX Stock Fund. Upon attaining the age of fifty-five, a participant may elect to change the investment of any matching contributions made on his behalf. Total Company match for any participant in the Plan can not exceed 3% of eligible compensation for the Plan year.

Non-discretionary Contribution

The Company will make an annual contribution equal to 5% of eligible compensation.

Discretionary Contribution

The Company may make an annual contribution between 0% - 5% of eligible compensation. The contribution amount is subject to approval by the Company’s Board of Directors. In 2009 and 2008, the Company's Board of Directors approved a 5% discretionary match.

Participant Accounts

Each participant’s account is credited with the participant’s contribution and allocations of the Company’s contribution and Plan earnings and charged with an allocation of administrative expenses. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Vesting

Each participant shall be fully vested and have a non-forfeitable interest in his account including all company contributions.

Payment of Benefits

Benefits under the Plan shall be payable to a participant or beneficiary upon the earlier of such participant's separation from service, disability, or death in a lump-sum payment or in installments over a period not to exceed 10 years.

2.	Significant Accounting Policies

Basis of Accounting

The financial statements of the Plan are presented on the accrual basis of accounting.

Employer contributions under the non-discretionary contribution feature include amounts equal to the aggregate amount that would have been contributed based on a participant’s eligible compensation under the non-discretionary contribution feature of the AVX Retirement Plan. The employer contributions associated with the discretionary contribution feature of the Plan are not readily determinable until after the Company’s fiscal year ended March 31 and are included in the Plan in the year paid. Contributions from employees are recorded in the period withheld.

Payment of Benefits

Benefits are recorded when paid.

Income Recognition

For purposes of determining realized gains and losses, the Plan uses the average cost method to determine the cost basis of disposed assets. Unrealized gains (losses) on investments on the Statements of Income and Changes in Plan Equity with Fund Information represents the cumulative change in unrealized gains (losses) for the respective years. Purchases and sales are recorded on the trade date.

Administrative Expenses

The Plan invests in various mutual funds with revenue-sharing agreements that partially offset fees. Plan fees that are not offset with revenue from these agreements are paid by the Company. In addition, the Company pays Plan fees related to stock administration of the AVX Stock Fund and the Kyocera Stock Fund. These stock administration fees are based on the market value of these funds.

Use of Estimates

The preparation of the Plan’s financial statements in conformity with generally accepted accounting principles requires the plan administrator to make significant estimates and assumptions that affect the reported amounts of plan equity at the date of the financial statements and the changes in plan equity during the reporting period and, when applicable, disclosures of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

Dividend and Interest Income Recognition

Interest income is accrued when earned. Dividend income is recorded on the ex-dividend date.

Investment Valuation

The Plan investments are stated at fair value. See Note 4.

Reclassifications

Certain items in the statements of income and changes in plan equity with fund information and Note 3 as originally reported for the years ended December 31, 2009 and 2008, have been reclassified to conform to the current presentation, as follows:

Realized gain (loss) on investments and unrealized gain (loss) on investments were segregated from net appreciation (depreciation) on investments to enhance presentation in the statements of income and changes in plan equity with fund information for the years ended December 31, 2009 and 2008.

The Plan's realized and unrealized gains (losses) for the years ended December 31, 2009 and 2008 presented in the table in Note 3 were segregated between common stock and other investments, also to enhance presentation.

These items have no effect on previously reported statements of financial condition with fund information or on the income (loss) and changes in plan equity for the years ended December 31, 2009 and 2008.

New Accounting Standards

In January 2010, the FASB issued ASU No. 2010-06, Improving Disclosures About Fair Value Measurements (ASC) 820, Fair Value Measurements and Disclosures (ASC 820) to add new disclosures about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances and settlements relating to Level 3 measurements. ASU 2010-06 also clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques used to measure fair value. This ASU is effective for the first reporting period beginning after December 15, 2009, except for the requirement to provide Level 3 activity of purchases, sales, issuances and settlements on a gross basis, which will be effective for fiscal years beginning on or after December 15, 2010. The Plan has adopted this guidance which did not have a material impact on the Plan’s financial statements and disclosures.

The fund invests at least 80% of net assets in the common stocks of "value" companies with large market capitalization ($4 billion or more) at the time of purchase. It generally holds a small number of securities because the investment manager believes doing so allows it to adhere to its disciplined value investment approach.

This fund had seven participants at December 31, 2010.

4.	Fair Value:

Fair Value Hierarchy:

The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to value the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined as follows:

§	Level 1: Unadjusted quoted prices in active markets for identical assets and liabilities.

§	Level 2: Observable inputs other than those included in Level 1. For example, quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets.

§	Level 3: Unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability.

				Based on

6.	Plan Termination

Although the Company has not expressed any intent to do so, it has the right to terminate the Plan at any time. However, termination of the Plan shall not, without the consent of a participant, adversely affect such participant’s rights with respect to amounts then accrued in his/her account.

-12-

7. Federal Income Taxes

The Plan is a grantor type trust and is not qualified under Section 401 of the Internal Revenue Code. Under Section 671 of the Internal Revenue Code, items of income, deduction or credit in a grantor trust are treated as belonging to the grantor. These items are reported on the income tax return of the grantor, AVX Corporation. Participants must include distributions in taxable income at the time of withdrawal.

For the Plan year 2008, certain participant contributions were made to the plan before all eligibility criteria was met. The compensation of these participants was not yet in excess of the amount determined under Section 401(a)(17) of the Code for the Plan year 2008. These amounts totaling $2,912 related to the employee contribution and $2,912 related to the employer match, net of any gains and losses, were transferred into a forfeiture account into the MainStay Cash Reserves Fund and reflected as net employee and employer receivables and payables between the funds in the accompanying statement of financial condition as of December 31, 2008. The gross amount of excess contributions was distributed to the participants by the Company. As discussed in Note 1 above, the Plan was amended effective January 1, 2010. The amendment to the Plan eliminated the Supplemental Retirement portion of the Plan with the related eligibility criteria.

8. Transactions with Related Parties

All transactions in AVX common stock and Kyocera ADS are related party transactions.

Amounts of American Depository Shares of Kyocera Corporation, the Company’s majority shareholder, held by the Plan at December 31 are as follows:

	2010		2009
Shares		9,262		11,462
Market value per share	$	102.18	$	88.31
Market value	$	946,391	$	1,012,209

Amounts of AVX Corporation common stock held by the Plan at December 31 are as follows:

	2010		2009
Shares		75,928		98,038
Market value per share	$	15.43	$	12.67
Market value	$	1,171,569	$	1,242,142

9. Risks and Uncertainties

The Plan provides for various investment options in common stocks, a money market fund, and in registered investment companies which invest in combinations of stocks, bonds, fixed income securities, mutual funds, and other investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that such changes could materially affect participants’ account balances and the amounts reported in the Statement of Financial Condition with Fund Information. The market value of the Plan’s assets is included as an asset and a liability on the Company’s balance sheet because the Plan’s assets are available to AVX’s general creditors in the event of the Company’s insolvency.
