| Summary of Significant Accounting Policies [Text Block] | Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements of Arrow Electronics, Inc. (the “company” or “Arrow”) include the accounts of the company, its majority-owned subsidiaries, and Arrow EMEA Funding Corp B.V. (see Note 5). All significant intercompany transactions are eliminated. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States ("GAAP") requires the company to make significant estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Cash and Cash Equivalents Cash equivalents consist of highly liquid investments, which are readily convertible into cash, with original maturities of three months or less. Trade Accounts and Notes Receivable Trade accounts and notes receivable are reported at amortized cost, net of the allowance for credit losses in the consolidated balance sheets. The allowance for credit losses is a valuation account that is deducted from the receivables' amortized cost basis to present the net amount expected to be collected. Receivables are written off against the allowance when management believes the receivable balance is confirmed to be uncollectible. Management estimates the allowance for credit losses using relevant available information about expected credit losses and an age-based reserve model. Inputs to the model include information about historical credit losses, customer credit ratings, past events, current conditions, and reasonable and supportable forecasts. Adjustments to historical loss information are made for differences in current receivable-specific risk characteristics such as changes in the economic and industry environment, or other relevant factors. Expected credit losses are estimated on a collective (pool) basis, when similar risk characteristics exist, based on customer credit ratings, which include both externally acquired as well as internally determined credit ratings. Receivables that do not share risk characteristics are evaluated on an individual basis. Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined on a moving average cost basis, which approximates the first-in, first-out method. Substantially all inventories represent finished goods held for sale. Property, Plant, and Equipment Property, plant, and equipment are stated at cost. Depreciation is computed on the straight-line method over the estimated useful lives of the assets. The estimated useful lives for depreciation of buildings is generally 20 to 30 years, and the estimated useful lives of machinery and equipment is generally three to ten years. Leasehold improvements are amortized over the shorter of the term of the related lease or the life of the improvement. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. If the carrying value of the asset cannot be recovered from estimated future cash flows, undiscounted and without interest, the fair value of the asset is calculated using the present value of estimated net future cash flows. If the fair value is less than the carrying amount of the asset, a loss is recognized for the difference, subject to the limitation of individual asset fair values within the group. Software Development Costs The company capitalizes certain internal and external costs incurred to acquire or create internal-use software. Capitalized software costs are amortized on a straight-line basis over the estimated useful life of the software, which is generally three to twelve years. At December 31, 2020 and 2019, the company had unamortized software development costs of $453,407 and $501,190, respectively, which are included in "Machinery and equipment" in the company's consolidated balance sheets. Identifiable Intangible Assets Amortization of definite-lived intangible assets is computed on the straight-line method over the estimated useful lives of the assets. Identifiable intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. Investments Investments are accounted for using the equity method if the investment provides the company the ability to exercise significant influence, but not control, over an investee. Significant influence is generally deemed to exist if the company has an ownership interest in the voting stock of the investee between 20% and 50%, although other factors, such as representation on the investee's Board of Directors, are considered in determining whether the equity method is appropriate. The company records its investments in equity method investees meeting these characteristics as "Investments in affiliated companies" in the company's consolidated balance sheets. Equity investments which the company does not possess the ability to exercise significant influence, are measured at fair value, using quoted market prices, and are included in “Other assets” in the company's consolidated balance sheets. Changes in fair value are recorded in “Gain (Loss) on investments, net” in the company's consolidated statements of operations. During the year ended December 31, 2020, the company recorded a net gain on investments of $5,348. The company records equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes. Goodwill Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. The company tests goodwill for impairment annually as of the first day of the fourth quarter and/or when an event occurs or circumstances change such that it is more likely than not that an impairment may exist. Examples of such events and circumstances that the company would consider include the following: • macroeconomic conditions such as deterioration in general economic conditions, limitations on accessing capital, fluctuations in foreign exchange rates, or other developments in equity and credit markets; • industry and market considerations such as a deterioration in the environment in which the company operates, an increased competitive environment, a decline in market-dependent multiples or metrics (considered in both absolute terms and relative to peers), a change in the market for the company's products or services, or a regulatory or political development; • cost factors such as increases in inventory, labor, or other costs that have a negative effect on earnings and cash flows; • overall financial performance such as negative or declining cash flows or a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods; • other relevant entity-specific events such as changes in management, key personnel, strategy, or customers, contemplation of bankruptcy, or litigation; • events affecting a reporting unit such as a change in the composition or carrying amount of its net assets, a more likely than not expectation of selling or disposing all, or a portion, of a reporting unit, the testing for recoverability of a significant asset group within a reporting unit, or recognition of a goodwill impairment loss in the financial statements of a subsidiary that is a component of a reporting unit; and • a sustained decrease in share price (considered in both absolute terms and relative to peers). Goodwill is tested at a level of reporting referred to as “the reporting unit.” The company's reporting units are defined as each of the three regional businesses within the global components business segment, which are the Americas; Europe, the Middle East, and Africa (“EMEA”); and Asia-Pacific, each of the two regional businesses within the global ECS business segment, which are North America and EMEA, and eInfochips, which was acquired in 2018 and is part of the global components business segment. An entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (that is, a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then the quantitative goodwill impairment test is unnecessary. The company has elected not to perform the qualitative assessment and performed the quantitative goodwill impairment test. The quantitative goodwill impairment test, used to identify both the existence of impairment and the amount of impairment loss, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of the reporting unit is less than its fair value, no impairment exists. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. The company estimates the fair value of a reporting unit using the income approach. For the purposes of the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. The assumptions included in the income approach include forecasted revenues, gross profit margins, operating income margins, working capital cash flow, perpetual growth rates, income tax rates, and long-term discount rates, among others, all of which require significant judgments by management. Actual results may differ from those assumed in the company's forecasts. The company also reconciles its discounted cash flow analysis to its current market capitalization allowing for a reasonable control premium. During the second quarter of 2019, the company recorded a goodwill impairment charge of $509,000 and $61,175 within the Americas components and Asia-Pacific components reporting units, respectively (see Note 3). During the first quarter of 2020, as a result of significant declines in macroeconomic conditions and equity valuations, and the implementation of regulatory restrictions brought forth by the COVID-19 pandemic, and due to historically low head-room, the company determined that it was more likely than not that an impairment may exist within the Americas components and eInfochips reporting units. The company performed a quantitative goodwill impairment test for these reporting units and determined goodwill was not impaired (see Note 3). While there is ongoing uncertainty related to COVID-19, the company has observed continued improvements in macroeconomic conditions and equity valuations, and market conditions related to our components business, along with improvements in working capital in certain reporting units. As of the first day of the fourth quarters of 2020, 2019, and 2018, the company's annual impairment testing did not indicate additional impairment at any of the company's reporting units. A decline in general economic conditions or global equity valuations could impact the judgments and assumptions about the fair value of the company's businesses, and the company could be required to record an impairment charge in the future, which could impact the company's consolidated balance sheets, as well as the company's consolidated statements of operations. If the company was required to recognize an impairment charge in the future, the charge would not impact the company's consolidated cash flows, current liquidity, capital resources, and covenants under its existing revolving credit facility, North American asset securitization program, other outstanding borrowings, and EMEA asset securitization program. As of December 31, 2020, the company has $2,115,469 of goodwill, of which approximately $607,315 and $90,463 was allocated to the Americas and EMEA reporting units within the global components business segment, respectively, $787,675 and $432,819 was allocated to the North America and EMEA reporting units within the global ECS business segment, respectively, and $197,197 was allocated to the eInfochips reporting unit. As of the date of the company's latest impairment test, the fair value of the EMEA components reporting unit, within the global components business segment, and the Americas ECS and EMEA ECS reporting units, within the global ECS business segment, exceeded their carrying values by more than 175%. The Americas components and eInfochips reporting units, within the global components business segment, exceeded their carrying values by less than 10% (see Note 3). Leases The company determines if a contract contains a lease at inception based on whether it conveys the right to control the use of an identified asset. Substantially all of the company's leases are classified as operating leases. The company records operating lease right-of-use assets within “Other assets” and lease liabilities are recorded within “Other liabilities” and “Accrued expenses” in the consolidated balance sheets. Lease expenses are recorded within “Selling, general, and administrative expenses” in the consolidated statements of operations. Operating lease payments are presented within “Operating cash flows” in the consolidated statements of cash flows. Operating lease right-of-use assets and lease liabilities are recognized based on the net present value of future minimum lease payments over the lease term starting on the commencement date. The company generally is not able to determine the rate implicit in its leases and, as such, applies an incremental borrowing rate based on the company's cost of borrowing for the relevant terms of each lease. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Lease terms may include an option to extend or terminate a lease if it is reasonably certain that the company will exercise such options. The company has elected the practical expedient to not separate lease components from non-lease components, and also has elected not to record a right-of-use asset or lease liability for leases which, at inception, have a term of twelve months or less. Variable lease payments are recognized in the period in which the obligation for those payments is incurred. Foreign Currency Translation and Remeasurement The assets and liabilities of international operations are translated at the exchange rates in effect at the balance sheet date. Revenue and expense accounts are translated at the monthly average exchange rates. Adjustments arising from the translation of the foreign currency financial statements of the company's international operations are reported as a component of “Accumulated other comprehensive loss” in the company's consolidated balance sheets. For foreign currency remeasurement from each local currency into the appropriate functional currency, monetary assets and liabilities are remeasured to functional currencies using current exchange rates in effect at the balance sheet date. Gains or losses from these remeasurements were not significant and have been included in the company's consolidated statements of operations. Non-monetary assets and liabilities are recorded at historical exchange rates. Income Taxes Income taxes are accounted for under the liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of differences between the tax bases of assets and liabilities and their financial reporting amounts using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The carrying value of the company's deferred tax assets is dependent upon the company's ability to generate sufficient future taxable income in certain tax jurisdictions. Should the company determine that it is more likely than not that some portion or all of its deferred tax assets will not be realized, a valuation allowance to reduce the deferred tax assets is established in the period such determination is made. The assessment of the need for a valuation allowance requires considerable judgment on the part of management with respect to the benefits that could be realized from future taxable income, as well as other positive and negative factors. It is also the company's policy to provide for uncertain tax positions and the related interest and penalties based upon management's assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. To the extent the company prevails in matters for which a liability for an unrecognized tax benefit is established, or is required to pay amounts in excess of the liability, or when other facts and circumstances change, the company's effective tax rate in a given financial statement period may be materially affected. Net Income (Loss) Per Share Basic net income (loss) per share is computed by dividing net income (loss) attributable to shareholders by the weighted-average number of common shares outstanding for the period. Diluted net income (loss) per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. Comprehensive Income (Loss) Comprehensive income (loss) consists of consolidated net income (loss), foreign currency translation adjustment, unrealized gains or losses on post-retirement benefit plans, unrealized gains on foreign exchange contracts designated as net investment hedges, and unrealized gains and losses on interest rate swaps designated as cash flow hedges. Unrealized gains or losses on interest rate swaps, and foreign exchange contracts are net of any reclassification adjustments for realized gains or losses included in consolidated net income. Amounts related to net investment hedges that are excluded from the assessment of hedge effectiveness are amortized to “interest and other financing expenses, net” on a straight-line basis over the life of the hedging instrument. Foreign currency translation adjustments included in comprehensive income (loss) which are deemed permanent investments in international affiliates were not tax effected. All other comprehensive income (loss) items are net of related income taxes. Stock-Based Compensation The company records share-based payment awards exchanged for employee services at fair value on the date of grant and expenses the awards in the consolidated statements of operations over the requisite employee service period. Stock-based compensation expense includes an estimate for forfeitures. Stock-based compensation expense related to awards with a market or performance condition which cliff vest, are recognized over the vesting period on a straight-line basis. Stock-based compensation awards with service conditions only are also recognized on a straight-line basis. Segment Reporting Operating segments are defined as components of an enterprise for which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The company's operations are classified into two reportable business segments: global components and global ECS. Revenue Recognition The company recognizes revenue as control of products is transferred to customers, which generally happens at the point of shipment. Sales are recorded net of discounts, rebates, and returns, which historically have not been material. The company allows its customers to return product for exchange or credit in limited circumstances. A liability is recorded at the time of sale for estimated product returns based upon historical experience. The company also provides volume rebates and other discounts to certain customers which are considered variable consideration. A provision for customer rebates and other discounts is recorded as a reduction of revenue at the time of sale based on an evaluation of the contract terms and historical experience. Tariffs are included in sales as the company has enforceable rights to additional consideration to cover the cost of tariffs. Other taxes imposed by governmental authorities on the company's revenue producing activities with customers, such as sales taxes and value added taxes, are excluded from net sales. Products sold by the company are generally delivered via shipment from the company's facilities, drop shipment directly from the vendor, or by electronic delivery of keys for software products. A portion of the company's business involves shipments directly from its suppliers to its customers, in these transactions, the company is generally responsible for negotiating price both with the supplier and customer, payment to the supplier, establishing payment terms with the customer, product returns, and has risk of loss if the customer does not make payment. As the principal with the customer, the company recognizes revenue upon receiving notification from the supplier that the product was shipped. The company has contracts with certain customers where the company's performance obligation is to arrange for the products or services to be provided by another party. In these arrangements, as the company assumes an agency relationship in the transaction, revenue is recognized in the amount of the net fee associated with serving as an agent. These arrangements relate to the sale of supplier service contracts to customers where the company has no future obligation to perform under these contracts or the rendering of logistics services for the delivery of inventory for which the company does not assume the risks and rewards of ownership. No single customer accounted for more than 2% of the company's 2020 consolidated sales. One supplier accounted for approximately 14% of the company's consolidated sales in 2020. No other single supplier accounted for more than 7% of the company's consolidated sales in 2020. The company believes that many of the products it sells are available from other sources at competitive prices. However, certain parts of the company's business, such as the company's global ECS business segment, rely on a limited number of suppliers with the strategy of providing focused support, extensive product knowledge, and customized service to suppliers, MSPs, and VARs. Most of the company's purchases are pursuant to distributor agreements, which are typically non-exclusive and cancelable by either party at any time or on short notice. Shipping and Handling Costs The company reports shipping and handling costs, primarily related to outbound freight, in the consolidated statements of operations as a component of selling, general, and administrative expenses. Shipping and handling costs included in selling, general, and administrative expenses totaled $95,634, $97,227, and $103,553 in 2020, 2019, and 2018, respectively. Vendor Programs The company participates in supplier programs that provide for price protection, product rebates, marketing/promotional allowances, and other incentives. The consideration received under these programs is recorded in the consolidated statements of operations as an adjustment to cost of goods sold or selling, general, and administrative expenses, according to the nature of the activity and terms of the vendor program. Incentives are accrued as they are earned based on sales of qualifying products or as services are provided in accordance with the terms of the related program. Impact of Recently Issued Accounting Standards In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-04, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU No. 2020-04"). ASU No. 2020-04 provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848) . This ASU provides supplemental guidance and clarification to ASU No. 2020-04, and these updates must be adopted concurrently, cumulatively referred to as “Topic 848.” The amendments in Topic 848 are effective for all entities as of March 12, 2020 through December 31, 2022. The company adopted the provisions of Topic 848 on a prospective basis in March 2020, and the adoption had no impact on the consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses ("Topic 326"). Topic 326 revises the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. On January 1, 2020, the company adopted Topic 326 using a modified retrospective approach with a cumulative effect adjustment to the opening balance of retained earnings, which increased the allowance for credit losses by $47,011 ($35,935 net of tax). Increases in the allowance for credit losses relate to the required change from an incurred loss model to an expected loss model, and the related change in timing of loss recognition where an allowance for credit losses is now applied to all receivables, at a rate dependent on the credit characteristics of the collective pool each customer is in. Refer to Note 5. Reclassification Certain prior period amounts were reclassified to conform to the current period presentation. These reclassifications did not have a material impact on previously reported amounts. |
