Basis of Presentation [Abstract]
Basis of Presentation	1. Basis of Presentation:  The consolidated financial statements of AVX Corporation and its subsidiaries (“AVX” or the “Company”) include all accounts of the Company and its subsidiaries. All significant intercompany transactions and accounts have been eliminated. We have prepared the accompanying financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. These consolidated financial statements are unaudited and, in the opinion of management, include all adjustments, consisting of normal recurring adjustments and accruals, necessary for the fair statement of the consolidated balance sheets, operating results, comprehensive income (loss), and cash flows for the periods presented. Operating results for the three and nine month periods ended December 31, 2016 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2017 due to changes in economic conditions and other factors. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been omitted in accordance with the rules and regulations of the SEC. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2016.  Critical Accounting Policies and Estimates: We have identified the accounting policies and estimates that are critical to our business operations and understanding our results of operations. Those policies and estimates can be found in Note 1, “Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements and in “Critical Accounting Policies and Estimates,” in “Management's Discussion and Analysis of Financial Condition and Results of Operations” contained in our Annual Report on Form 10-K for the fiscal year ended March 31, 2016. Accordingly, this Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended March 31, 2016. During the three and nine month periods ended December 31, 2016, there were no significant changes to any critical accounting policies or to the methodology used in determining estimates, including those related to investment securities, revenue recognition, inventories, goodwill, intangible assets, property and equipment, income taxes, and contingencies.  New Accounting Standards In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” This guidance modifies the financial reporting of revenue and how an entity will determine the measurement of revenue and timing of when it is recognized. The guidance provides for a five-step approach in applying the standard: 1) identifying the contract with the customer, 2) identifying separate performance obligations in the contract, 3) determining the transaction price, 4) allocating the transaction price to separate performance obligations, and 5) recognizing the revenue when the performance obligation has been satisfied. The new guidance requires enhanced disclosures for the nature, amount, timing, and uncertainty of revenue that is being recognized. The guidance is effective for public companies for interim and annual reporting periods beginning after December 15, 2017. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. Early adoption is permitted. Management is currently evaluating the impact of this guidance on our consolidated financial statements. In February 2016, FASB issued ASU 2016-2, “Leases.” This guidance changes the inclusion of certain right-of-use assets and the associated lease liabilities to be included in a statement of financial position. The classification criteria maintains the distinction between finance leases and operating leases. Regarding financial leases, lessees are required to 1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, 2) recognize interest on the lease liability separate from the amortization of the right-of-use asset in the statement of comprehensive income, and 3) classify repayments of the principal portion of the lease liability within financing activities and payments of interest on the lease liability and variable lease payments within operating activities in the statement of cash flows. Regarding operating leases, lessees are required to 1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, 2) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis, and 3) classify all cash payments within operating activities in the statement of cash flows. This guidance is effective for public companies for interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted. Management is currently evaluating the impact of this guidance on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation — Stock Compensation.” The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. The guidance is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Management is currently evaluating the impact of this guidance on our consolidated financial statements. We have reviewed other newly issued accounting pronouncements and concluded that they are either not applicable to our business or that no material effect is expected on our consolidated financial statements as a result of future adoption.

Earnings Per Share [Abstract]
Earnings Per Share	2. Earnings Per Share:  Basic earnings per share are computed by dividing net earnings by the weighted average number of shares of common stock outstanding for the period. Diluted earnings per share are computed by dividing net earnings by the sum of (a) the weighted average number of shares of common stock outstanding during the period and (b) the dilutive effect of potential common stock equivalents during the period. Stock options are the only common stock equivalents currently used in our calculation and are computed using the treasury stock method.  The table below represents the basic and diluted earnings per share and sets forth the weighted average number of shares of common stock outstanding and the dilutive effect of potential common stock equivalents:    Three Months Ended Nine Months Ended  December 31, December 31,  2015 2016 2015 2016  Net income $ 5,374 $ 35,519 $ 68,870 $ 91,928  Computation of Basic EPS:  Weighted Average Shares Outstanding used in Computing Basic EPS 167,655 167,418 167,883 167,399  Basic earnings per share $ 0.03 $ 0.21 $ 0.41 $ 0.55  Computation of Diluted EPS:  Weighted Average Shares Outstanding used in Computing Basic EPS 167,655 167,418 167,883 167,399  Effect of stock options 178 438 200 265  Weighted Average Shares used in Computing Diluted EPS (1) 167,833 167,856 168,083 167,664  Diluted earnings per share $ 0.03 $ 0.21 $ 0.41 $ 0.55   (1) Common stock equivalents not included in the computation of diluted earnings per share because the impact would have been antidilutive were 2,725 shares and 776 shares for the three months ended December 31, 2015 and 2016, respectively, and 2,548 shares and 1,580 shares for the nine months ended December 31, 2015 and 2016, respectively.

Fair Value

Fair Value	9 Months Ended

Fair Value [Abstract]
Fair Value	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.  During the three and nine month periods ended December 31, 2015 and 2016, there have been no transfers of assets or liabilities between levels within the fair value hierarchy.

(2) Foreign currency derivatives in the form of forward contracts are included in prepaid and other and accrued expenses in the consolidated balance sheets. Unrealized gains and losses on derivatives classified as cash flow hedges are recorded in other comprehensive income (loss). Realized gains and losses on derivatives classified as cash flow hedges are recorded in the consolidated statement of operations as revenues and costs of sales, and gains and losses on derivatives not designated as cash flow hedges are recorded in other income.  Valuation Techniques:  The following describes valuation techniques used to appropriately value our assets held in the non-qualified deferred compensation plan and derivatives.  Assets held in the non-qualified deferred compensation plan  Assets valued using Level 1 and Level 2 inputs in the table above represent assets from our non-qualified deferred compensation program. The funds in the non-qualified deferred compensation program are valued based on the number of shares in the funds using a price per share traded in an active market.  Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. If the cost of an investment exceeds its fair value, among other factors, we evaluate general market conditions, the duration and extent to which the fair value is less than cost, and whether or not we expect to recover the security's entire amortized cost basis. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis in the investment is established.  Derivatives  We primarily use forward contracts, with maturities generally less than four months, designated as cash flow hedges to protect against the foreign currency exchange rate risks inherent in our forecasted transactions related to purchase commitments and sales, denominated in various currencies. We also use derivatives not designated as hedging instruments to hedge foreign currency balance sheet exposures. These derivatives are used to offset currency changes in the fair value of the hedged assets and liabilities. Fair values for all of our derivative financial instruments are valued by adjusting the market spot rate by forward points, based on the date of the contract. The spot rates and forward points used are an average rate from an actively traded market. At March 31, 2016 and December 31, 2016, all of our forward contracts are valued using Level 2 measurements.

Financial Instruments and Investments in Securities [Abstract]
Financial Instruments and Investments in Securities	5. Financial Instruments and Investments in Securities:  At March 31, 2016 and December 31, 2016, we classified investments in debt securities and time deposits as held-to-maturity securities.  Our long-term and short-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.  Investments in held-to-maturity securities, recorded at amortized cost, were as follows:    March 31, 2016  Gross Gross  Unrealized Unrealized Estimated  Cost Gains Losses Fair Value  Short-term investments:  Time deposits $ 494,594 $ 296 $ - $ 494,890  Long-term investments:  Corporate bonds 85,577 39 (28) 85,588  $ 580,171 $ 335 $ (28) $ 580,478      December 31, 2016  Gross Gross  Unrealized Unrealized Estimated  Cost Gains Losses Fair Value  Short-term investments:  Corporate bonds $ 10,233 $ - $ (7) $ 10,226  Time deposits 614,408 274 - 614,682  $ 624,641 $ 274 $ (7) $ 624,908   The amortized cost and estimated fair value of held-to-maturity investments at December 31, 2016, by contractual maturity, are shown below. The estimated fair value of these investments are based on valuation inputs that include benchmark yields, reported trades, broker and dealer quotes, issuer spreads, two-sided markets, benchmark securities bids, offers, and reference data, which are Level 2 inputs in the fair value hierarchy. Actual maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations without call or prepayment penalties.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	7. Commitments and Contingencies:  We have been identified by the United States Environmental Protection Agency (“EPA”), state governmental agencies or other private parties as a potentially responsible party (“PRP”) under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) or equivalent state or local laws for clean-up and response costs associated with certain sites at which remediation is required with respect to prior contamination. Because CERCLA or such state statutes authorize joint and several liability, the EPA or state regulatory authorities could seek to recover all clean-up costs from any one of the PRPs at a site despite the involvement of other PRPs. At certain sites, financially responsible PRPs other than AVX also are, or have been, involved in site investigation and clean-up activities. We believe that liability resulting from these sites will be apportioned between AVX and other PRPs.  To resolve our liability at the sites at which we have been named a PRP, we have entered into various administrative orders and consent decrees with federal and state regulatory agencies governing the timing and nature of investigation and remediation. As is customary, the orders and decrees regarding sites where the PRPs are not themselves implementing the chosen remedy contain provisions allowing the EPA to reopen the agreement and seek additional amounts from settling PRPs in the event that certain contingencies occur, such as the discovery of significant new information about site conditions.  On June 3, 2010, AVX entered into an agreement with the EPA and the City of New Bedford, pursuant to which AVX is required to perform environmental remediation at a site referred to as the “Aerovox Site” (the “Site”), located in New Bedford, Massachusetts. AVX has substantially completed its obligations pursuant to such agreement with the EPA and the City of New Bedford with respect to the satisfaction of AVX’s federal law requirements. Agreements with the state regulatory authorities have yet to be concluded but are likely to include additional groundwater and soil remediation. We have a remaining accrual of $15,083 at December 31, 2016, including a $3,600 charge recorded in the quarter ended June 30, 2016, representing our estimate of the potential liability related to the remaining performance of environmental remediation actions at the Site using certain assumptions regarding the plan of remediation. Since additional sampling and analysis may cause the state regulatory authority, the Massachusetts Department of Environmental Protection, to require a more extensive and costly plan of remediation, until all parties agree and remediation is complete, we cannot be certain there will be no additional cost relating to the Site.  We had total reserves of approximately $ 16,809 and $ 19,720 at March 31, 2016 and December 31, 2016, respectively, related to various environmental matters, including the site discussed above. These reserves are classified in the Consolidated Balance Sheets as $ 7,409 and $ 4,226 in accrued expenses at March 31, 2016 and December 31, 2016, respectively, and $9,400 and $ 15,494 in other non-current liabilities at March 31, 2016 and December 31, 2016, respectively. The amounts recorded for these identified contingent liabilities are based on estimates. Amounts recorded are reviewed periodically and adjusted to reflect additional legal and technical information that becomes available. Also, uncertainties about the status of laws, regulations, regulatory actions, technology, and information related to individual sites make it difficult to develop an estimate of the reasonably possible aggregate environmental remediation exposure. Accordingly, these costs could differ from our current estimates.  On April 19, 2016, the Canadian Ministry of the Environment and Climate Change (the “MoE”) issued a Director’s Order naming AVX Corporation, as well as others, as responsible parties with respect to a location in Hamilton, Ontario that was the site of operations of Aerovox Canada, a former subsidiary of Aerovox Corporation, a predecessor of AVX. This Director’s Order follows a draft order issued on November 4, 2015. AVX has taken the position that any liability of Aerovox Canada for such site under the laws of Canada cannot be imposed on AVX. At present, it is unclear whether the MoE will seek to enforce such Canadian order against AVX, and whether, in the event it does so, AVX will have any liability under applicable law. AVX intends to contest any such course of action that may be taken by the MoE.  We also operate on other sites that may have potential future environmental issues as a result of activities at sites during AVX’s long history of manufacturing operations or prior to the start of operations by AVX. Even though we may have rights of indemnity for such environmental matters at certain sites, regulatory agencies in those jurisdictions may require us to address such issues. Once it becomes probable that we will incur costs in connection with remediation of a site and such costs can be reasonably estimated, we establish reserves or adjust our reserves for our projected share of these costs. A separate account receivable is recorded for any indemnified costs. Our environmental reserves are not discounted and do not reflect any possible future insurance recoveries, which are not expected to be significant, but do reflect a reasonable estimate of cost sharing at multiple-party sites or indemnification of our liability by a third party.  On April 25, 2013, AVX was named as a defendant in a patent infringement case filed in the United States District Court for the District of Delaware captioned Greatbatch, Inc. v. AVX Corporation (“Greatbatch”) . This case alleged that certain AVX products infringe on one or more of six Greatbatch patents. On January 26, 2016, the jury returned a verdict in favor of the plaintiff in the first phase of a segmented trial and found damages to Greatbatch in the amount of $37,500 . AVX is reviewing this initial verdict, consulting with its legal advisors on what action AVX may take in response, and continuing to litigate the rest of the case.  On September 2, 2014, a subsidiary of AVX, American Technical Ceramics (“ATC”), was named as a defendant in a patent infringement case filed in the United States District Court for the District of Delaware captioned Presidio Components, Inc. v. American Technical Ceramics Corp. This case alleged that certain products of ATC’s infringe on a Presidio patent. On April 18, 2016, the jury returned a verdict in favor of the plaintiff and found damages to Presidio in the amount of $2,168 . On August 17, 2016, the court issued a permanent injunction prohibiting ATC from manufacturing or selling the related product after November 16, 2016 and awarded Presidio damages related to ATC’s sale of such products from February 21, 2016 through November 16, 2016. Subsequently, on October 21, 2016, the Federal Circuit Court granted AVX’s request for a stay of the permanent injunction whereby AVX may continue to sell the disputed product until March 17, 2017 to anyone who was a customer prior to June 17, 2016. Any sales subsequent to November 16, 2016 pursuant to the stay of the permanent injunction are subject to court mandated intellectual property damages for each product sold. AVX is taking an estimated reserve for damages on all pre- and post-verdict sales of product subject to that litigation in the event that the verdict withstands future challenges. AVX has appealed the verdict.  We had total reserves of $39,668 and $67,800 as of March 31, 2016 and December 31, 2016, respectively, related to the two intellectual property cases discussed above. The amounts recorded are based on estimated outcomes. Amounts recorded are reviewed periodically and adjusted to reflect additional information that becomes available. Accordingly, these costs could differ from our current estimates.  During the quarter ended September 30, 2014, AVX was named as a co-defendant in a series of cases filed in the United States and in the Canadian provinces of Quebec, Ontario and British Columbia alleging violations of United States, Canadian, and state antitrust laws asserting that AVX and numerous other companies were participants in alleged price-fixing in the capacitor market. The cases in the United States were consolidated into the Northern District of California on October 2, 2014. During the quarter ended December 31, 2014, additional Canadian cases were filed in the provinces of Quebec, Ontario, British Columbia, Saskatchewan and Manitoba and these cases are at the initial stages. AVX believes it has meritorious defenses and intends to vigorously defend the cases.  We are involved in other disputes, warranty claims, and legal proceedings arising in the normal course of business. While we cannot predict the outcome of these other disputes and proceedings, management believes, based upon a review with legal counsel, that none of these proceedings will have a material impact on our financial position, results of operations, comprehensive income (loss), or cash flows. However, we cannot be certain of the eventual outcome, and any adverse result in these or other matters that may arise from time to time, may harm our financial position, results of operations, comprehensive income (loss), or cash flows.

Segment and Geographic Information [Abstract]
Segment and Geographic Information	9. Segment and Geographic Information:  Our operating segments are based on the types of products from which we generate revenues. We are organized into a product line organization with five main product groups and three reportable segments: Passive Components, KED Resale, and Interconnect. The product groups of Ceramic, Advanced, and Tantalum have been aggregated into the Passive Components reportable segment in accordance with the SEC’s aggregation criteria and quantitative thresholds. The aggregation criteria consist of similar economic characteristics, products and services, production processes, customer classes, and distribution channels. The Passive Components segment consists primarily of surface mount and leaded ceramic capacitors, RF thick and thin film components, surface mount and leaded tantalum capacitors, surface mount and leaded film capacitors, ceramic and film power capacitors, super capacitors, EMI filters (bolt in and surface mount), thick and thin film packages of multiple passive integrated components, varistors, thermistors, inductors, and resistive products manufactured by AVX or purchased from other manufacturers for resale. The Interconnect segment consists primarily of automotive, telecom, and memory connectors manufactured by or for AVX Interconnect. The KED Resale segment consists primarily of ceramic capacitors, frequency control devices, SAW devices, sensor products, RF modules, actuators, acoustic devices, and connectors produced by Kyocera and resold by AVX. In addition, we have a corporate administration group consisting of finance, legal, EHS, and administrative activities.  We evaluate performance of our segments based upon sales and operating profit. There are no intersegment revenues. We allocate the costs of shared resources between segments based on each segment ’ s usage of the shared resources. Cash, accounts receivable, investments in securities, and certain other assets, which are centrally managed, are not readily allocable to operating segments.

Derivative Financial Instruments [Abstract]
Derivative Financial Instruments	11. Derivative Financial Instruments:  We are exposed to foreign currency exchange rate fluctuations in the normal course of business. We use derivative instruments (forward contracts) to hedge certain foreign currency exposures as part of our risk management strategy. The objective is to offset gains and losses resulting from these exposures with gains and losses on the forward contracts used to hedge them, thereby reducing volatility of earnings or protecting fair values of assets and liabilities. We do not enter into any trading or speculative positions with regard to derivative instruments.  We primarily use forward contracts, with maturities less than four months, designated as cash flow hedges to protect against the foreign currency exchange rate risks inherent in our forecasted transactions related to purchase commitments and sales, denominated in various currencies. These derivative instruments are designated and qualify as cash flow hedges.  The effectiveness of the cash flow hedges is determined by comparing the cumulative change in the fair value of the hedge contract with the cumulative change in the fair value of the hedged transaction, both of which are based on forward rates. The effective portion of the gain or loss on these cash flow hedges is initially recorded in accumulated other comprehensive income (loss) as a separate component of stockholders’ equity. Once the hedged transaction is recognized, the gain or loss is recognized in our statement of operations. At March 31, 2016 and December 31, 2016, respectively, the following forward contracts were entered into to hedge against the volatility of foreign currency exchange rates for certain forecasted sales and purchases.     March 31, 2016  Fair Value of Derivative Instruments  Asset Derivatives Liability Derivatives  Balance Balance  Sheet Fair Sheet Fair  Caption Value Caption Value   Foreign exchange contracts Prepaid and other $ 1,125 Accrued expenses $ 869      December 31, 2016  Fair Value of Derivative Instruments  Asset Derivatives Liability Derivatives  Balance Balance  Sheet Fair Sheet Fair  Caption Value Caption Value   Foreign exchange contracts Prepaid and other $ 1,737 Accrued expenses $ 3,922    For these derivatives designated as hedging instruments, during the three and nine months ended December 31, 2016, net pre-tax gains (losses) of $ (3,002) and $(2,972) , respectively, were recognized in other comprehensive income (loss). In addition, during the three and nine months ended December 31, 2016, net pre-tax gains (losses) of $ (1,258) and $ (2,084) , respectively, were reclassified from accumulated other comprehensive income into cost of sales (for hedging purchases), and net pretax gains of $ 1,507 and $ 1,331 , respectively, were reclassified from accumulated other comprehensive income into sales (for hedging sales) in the accompanying statement of operations.  Derivatives not designated as cash flow hedging instruments consist primarily of forwards used to hedge foreign currency balance sheet exposures. These hedging instruments are used to offset foreign currency changes in the fair values of the underlying assets and liabilities. The gains and losses on these foreign currency forward contracts are recognized in other income in the same period as the remeasurement gains and losses of the related foreign currency denominated assets and liabilities and thus naturally offset these gains and losses. At March 31, 2016 and December 31, 2016, we had the following forward contracts that were entered into to hedge against these exposures.

At March 31, 2016 and December 31, 2016, we had outstanding foreign exchange contracts with notional amounts totaling $ 204,372 and $ 230,425 , respectively, denominated primarily in Euros, Czech Korunas, British Pounds, and Japanese Yen.

Basis of Presentation [Abstract]
New Accounting Standards	In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” This guidance modifies the financial reporting of revenue and how an entity will determine the measurement of revenue and timing of when it is recognized. The guidance provides for a five-step approach in applying the standard: 1) identifying the contract with the customer, 2) identifying separate performance obligations in the contract, 3) determining the transaction price, 4) allocating the transaction price to separate performance obligations, and 5) recognizing the revenue when the performance obligation has been satisfied. The new guidance requires enhanced disclosures for the nature, amount, timing, and uncertainty of revenue that is being recognized. The guidance is effective for public companies for interim and annual reporting periods beginning after December 15, 2017. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. Early adoption is permitted. Management is currently evaluating the impact of this guidance on our consolidated financial statements. In February 2016, FASB issued ASU 2016-2, “Leases.” This guidance changes the inclusion of certain right-of-use assets and the associated lease liabilities to be included in a statement of financial position. The classification criteria maintains the distinction between finance leases and operating leases. Regarding financial leases, lessees are required to 1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, 2) recognize interest on the lease liability separate from the amortization of the right-of-use asset in the statement of comprehensive income, and 3) classify repayments of the principal portion of the lease liability within financing activities and payments of interest on the lease liability and variable lease payments within operating activities in the statement of cash flows. Regarding operating leases, lessees are required to 1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, 2) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis, and 3) classify all cash payments within operating activities in the statement of cash flows. This guidance is effective for public companies for interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted. Management is currently evaluating the impact of this guidance on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation — Stock Compensation.” The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. The guidance is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Management is currently evaluating the impact of this guidance on our consolidated financial statements. We have reviewed other newly issued accounting pronouncements and concluded that they are either not applicable to our business or that no material effect is expected on our consolidated financial statements as a result of future adoption.
