Summary of Significant Accounting Policies
Consolidation Policy	Consolidation Policy The Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All significant inter-company accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates, including those related to the allowance for uncollectible accounts receivable and inventory reserves. Management bases its estimates on assumptions that management believes to be reasonable under the circumstances, the results of which form a basis for making judgments about the carrying value of assets and liabilities that are not readily available from other sources. Actual results may differ from these estimates under different assumptions or conditions; however, management believes that its estimates, including those for the above described items, are reasonable and that the actual results will not vary significantly from the estimated amounts. The following significant accounting policies relate to the more significant judgments and estimates used in the preparation of the Consolidated Financial Statements:
Allowances for Trade and Notes Receivable	(a) Allowances for Trade and Notes Receivable The Company maintains an allowance for uncollectible accounts receivable for estimated losses resulting from customers' failure to make payments on accounts receivable due to the Company. Management determines the estimate of the allowance for uncollectible accounts receivable by considering a number of factors, including: (1) historical experience, (2) aging of the accounts receivable and (3) specific information obtained by the Company on the financial condition and the current creditworthiness of its customers. If the financial condition of the Company's customers were to deteriorate and reduce the ability of the Company's customers to make payments on their accounts, the Company may be required to increase its allowance by recording additional bad debt expense. Likewise, should the financial condition of the Company's customers improve and result in payments or settlements of previously reserved amounts, the Company may be required to record a reduction in bad debt expense to reverse the recorded allowance. A provision for estimated losses on returns and allowances is recorded on historical experience.
Inventory Reserves	(b) Inventory Reserves Management determines the inventory reserves required to reduce inventories to the lower of cost or market based principally on the effects of technological changes, quantities of goods on hand, and other factors. An estimate is made of the market value, less cost to dispose, of products whose value is determined to be impaired. If these products are ultimately sold at less than estimated amounts, additional reserves may be required. The estimates used to calculate these reserves are applied consistently. The adjustments are recorded in the period in which the loss of utility of the inventory occurs, which establishes a new cost basis for the inventory. This new cost basis is maintained until such time that the reserved inventory is disposed of, returned to the vendor or sold. To the extent that specifically reserved inventory is sold, cost of goods sold is expensed for the new cost basis of the inventory sold.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation in the accompanying Consolidated Financial Statements.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company maintains three zero-balance, disbursement accounts at separate financial institutions in which the Company does not maintain significant depository relationships. Due to the nature of the Company's banking relationships with these institutions, the Company does not have the right to offset most if not all outstanding checks written from these accounts against cash on hand. Checks released but not yet cleared from these accounts in the amounts of $73.6 million and $62.7 million are classified to accounts payable as of June 30, 2011 and June 30, 2010, respectively.
Concentration of Credit Risk	Concentration of Credit Risk The Company sells its products to a large base of value-added resellers throughout North America, Latin America and Europe. The Company performs ongoing credit evaluations of its customers' financial condition. In certain cases, the Company will accept tangible assets as collateral to increase the trade credit of its customers. No single customer accounted for more than 5% of the Company's net sales for fiscal 2011, 2010, or 2009. The Company has established arrangements with certain customers for longer term financing. The Company accounts for these arrangements by recording them at their historical cost less specific allowances at balance sheet dates. Interest income is recognized in the period earned and is recorded as interest income in the Consolidated Income Statement. Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash. The Company maintains its cash with high credit quality financial institutions. At times, such investments may be in excess of FDIC insurance limits.
Derivative Financial Instruments	Derivative Financial Instruments The Company uses derivative instruments to manage certain exposures related to foreign currency as well as changes in interest rates as a result of our borrowing activities. We record all derivative instruments as either assets or liabilities in the balance sheet at fair value. The Company currently does not use derivative financial instruments for trading or speculative purposes. The Company's foreign currency exposure results from purchasing and selling internationally in several foreign currencies. In addition, the Company has foreign currency risk related to debt that is denominated in currencies other than the U.S. Dollar. The Company may reduce its exposure to fluctuations in foreign exchange rates by creating offsetting positions through the use of derivative financial instruments or multi-currency borrowings. The market risk related to the foreign exchange agreements is offset by changes in the valuation of the underlying items. Derivative financial instruments related to foreign currency exposure are accounted for on an accrual basis with gains or losses on these contracts recorded in income in the period in which their value changes, with the offsetting entry for unsettled positions reflected in either other assets or other liabilities. These contracts are generally for a duration of 90 days or less. The Company has elected not to designate its foreign currency contracts as hedging instruments. They are, therefore, marked-to-market with changes in their fair value recorded in the Consolidated Income Statement each period. The underlying exposures are denominated primarily by British Pounds, Euros, Mexican Pesos, Brazilian Real and Canadian Dollars. During the fiscal year ended June 30, 2008, the Company entered into an interest rate swap and designated this instrument as a hedge of the cash flows on certain variable rate debt. To the extent the derivative instrument is effective in offsetting the variability of the hedged cash flows, changes in the fair value of the derivative instrument will not be included in current earnings, but will be reported as other comprehensive income (loss). The ineffective portion, if any, will be recorded as an adjustment to earnings.
Investments	Investments The Company has investments that are held in a grantor trust formed by the Company related to the ScanSource, Inc. Nonqualified Deferred Compensation Plan and Founder's Supplemental Executive Retirement Plan ("SERP"). The Company has classified these investments as trading securities and they are recorded at fair market value with unrealized gains and losses included in the accompanying Consolidated Income Statements. The Company's obligations under this deferred compensation plan change in concert with the performance of the investments. The fair value of these investments and the corresponding deferred compensation obligation was $12.9 million and $8.1 million as of June 30, 2011 and June 30, 2010, respectively. These investments are classified as either current assets or other non-current assets in the Consolidated Balance Sheets depending on the timing of planned disbursements. The deferred compensation obligation is classified either within current liabilities or other long-term liabilities as well. The amounts of these investments classified as current assets with corresponding current liabilities were $3.1 million and $1.1 million at June 30, 2011 and June 30, 2010, respectively.
Inventories	Inventories Inventories (consisting entirely of finished goods) are stated at the lower of cost (first-in, first-out method) or market.
Vendor Programs	Vendor Programs The Company receives incentives from vendors related to cooperative advertising allowances, volume rebates and other incentive agreements. These incentives are generally under quarterly, semi-annual or annual agreements with the vendors. Some of these incentives are negotiated on an ad hoc basis to support specific programs mutually developed between the Company and the vendor. Vendors generally require that we use their cooperative advertising allowances exclusively for advertising or other marketing programs. Incentives received from vendors for specifically identified incremental cooperative advertising programs are recorded as adjustments to selling, general and administrative expenses. The Financial Accounting Standards Board's ("FASB") Accounting Standards Codification ("ASC") 605 – Revenue Recognition, addresses accounting by a customer (including a reseller) for certain consideration received from a vendor. This guidance requires that the portion of these vendor funds in excess of our costs be reflected as a reduction of inventory. Such funds are recognized as a reduction of the cost of products sold when the related inventory is sold. The Company records unrestricted volume rebates received as a reduction of inventory and as a reduction of the cost of goods sold when the related inventory is sold. Amounts received or receivables from vendors that are not yet earned are deferred in the Consolidated Balance Sheets. In addition, the Company may receive early payment discounts from certain vendors. The Company records early payment discounts received as a reduction of inventory and recognizes the discount as a reduction of cost of goods sold when the related inventory is sold. ASC 605 requires management to make certain estimates of the amounts of vendor incentives that will be received. Actual recognition of the vendor consideration may vary from management estimates based on actual results.
Vendor Concentration	Vendor Concentration The Company sells products from many suppliers, however, sales from products supplied by Motorola and Avaya each constituted more than 10% of the Company's net sales for years ended June 30, 2011, 2010 and 2009, respectively.
Product Warranty	Product Warranty The Company's vendors generally provide a warranty on the products distributed by the Company and allow the Company to return defective products, including those that have been returned to the Company by its customers. In one product line, the Company offers a self-branded warranty program, in which Management has determined that the Company is the primary obligor of these programs. The Company purchases contracts from unrelated third parties, generally the original equipment manufacturers, to fulfill any obligation to service or replace defective product claimed on these warranty programs. As such, the Company has not recorded a provision for estimated service warranty costs. For all other product lines, the Company does not independently provide a warranty on the products it distributes; however, to maintain customer relations, the Company facilitates returns of defective products from the Company's customers by accepting for exchange, with the Company's prior approval, most defective products within 30 days of invoicing.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over estimated useful lives of 3 to 10 years for furniture, equipment and computer software, 40 years for buildings and 15 years for building improvements. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life. Maintenance, repairs and minor renewals are charged to expense as incurred. Additions, major renewals and betterments to property and equipment are capitalized. In fiscal 2010, the Company began the implementation of a new Enterprise Resource Planning System ("ERP"). The compensation costs of employees associated with this implementation process are capitalized to the construction in process asset related to this project.
Goodwill	Goodwill The Company accounts for recorded goodwill in accordance with ASC 350, Goodwill and Other Intangible Assets, which requires that they are reviewed annually for impairment or more frequently if impairment indicators exist. See Note 6 for a discussion of the annual goodwill impairment test.
Intangible Assets	Intangible Assets Intangible assets consist of customer relationships, debt issuance costs, trade names, distributor agreements and non-compete agreements. Customer relationships and distributor agreements are amortized using the straight-line method over their estimated useful lives, which range from 5 to 15 years. Debt issuance costs are amortized over the term of the credit facility. Trade names are amortized over a period ranging from 1 to 2 years. Non-compete agreements are amortized over their contract life. These assets are included in other assets and are shown in detail in Note 6, "Goodwill and Other Identifiable Intangible Assets".
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset or asset group may not be recoverable. Tests for recoverability of a long-lived asset to be held and used are measured by comparing the carrying amount of the long-lived asset to the sum of the estimated future discounted cash flows expected to be generated by the asset. In estimating the future discounted cash flows we use projections of cash flows directly associated with, and which are expected to arise as a direct result of, the use and eventual disposition of the assets. If it is determined that a long-lived asset is not recoverable, an impairment loss would be calculated equal to the excess of the carrying amount of the long-lived asset over its fair value. The Company did not record any material impairment charges for the fiscal years ended June 30, 2011, 2010 and 2009.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value of financial instruments is the amount at which the instrument could be exchanged in a current transaction between willing parties. The carrying values of financial instruments such as accounts receivable, accounts payable, accrued liabilities, borrowings under the revolving credit facility and subsidiary lines of credit approximate fair value based upon either short maturities or variable interest rates of these instruments. For additional information related to the fair value of derivatives, please see Note 9, "Fair Value of Financial Instruments".
Liability for Contingent Consideration	Liability for Contingent Consideration In addition to the initial cash consideration paid to former CDC shareholders, the Company is obligated to make additional earnout payments throughout 2015 based on a multiple of the subsidiary's pro forma net income as defined in Exhibit 2.1.(b)(2) of the Share Purchase and Sale Agreement by and among the Company's Brazilian subsidiary, the former shareholders and CDC, dated April 7, 2011. Future payments are to be paid in Brazilian currency, the Real. The estimated first earnout payment of $2.4 million is to be made on August 31, 2011 based on the pro forma results of the twelve month period ended June 30, 2011. The remaining earnout payments will become payable in four additional installments on August 31, 2012 – 2014 with the final payment on October 31, 2015. In accordance with ASC Topic 805, the Company determined the fair value of this liability for contingent consideration on the acquisition date using a probability weighted income approach. Each period the Company will reflect the contingent consideration liability at fair value with changes recorded in selling, general and administrative expenses line item in the Consolidated Income Statements.
Contingencies	Contingencies The Company accrues for contingent obligations, including estimated legal costs, when it is probable that a liability is incurred and the amount is reasonably estimable. As facts concerning contingencies become known, management reassesses its position and makes appropriate adjustments to the financial statements. Estimates that are particularly sensitive to future changes include tax, legal, and other regulatory matters, which are subject to change as events evolve, and as additional information becomes available during the administrative and litigation process.
Revenue Recognition	Revenue Recognition Revenue is recognized once four criteria are met: (1) the Company must have persuasive evidence that an arrangement exists; (2) delivery must occur, which happens at the point of shipment (this includes the transfer of both title and risk of loss, provided that no significant obligations remain); (3) the price must be fixed and determinable; and (4) collectability must be reasonably assured. The Company allows its customers to return product for exchange or credit subject to certain limitations. A provision for estimated losses on returns is recorded based on historical experience. Service revenue associated with configuration and marketing services is recognized when the work is complete and the four criteria discussed above have been substantially met. The Company also distributes third-party service contracts, typically for product maintenance and support. Since the Company acts as an agent on behalf of most of these service contracts sold, revenue is recognized net of cost at the time of sale. However, the Company distributes some self-branded warranty programs and engages a third party (generally the original equipment manufacturer) to cover the fulfillment of any obligations arising from these contracts. These revenues and associated third party costs are amortized over the life of contract and presented in net sales and cost of goods sold, respectively. Service revenue associated with configuration, marketing, service contracts and other services has represented less than 2% of consolidated net sales for fiscal years 2011, 2010 and 2009. During the fiscal years ended June 30, 2011, 2010 and 2009, the Company has not engaged in any sales transactions involving multiple element arrangements. Had any arrangements with multiple deliverables occurred, The Company would follow the guidance set forth in ASC 605.
Shipping Revenue and Costs	Shipping Revenue and Costs Shipping revenue is included in net sales and related costs are included in cost of goods sold. Shipping revenue for the years ended June 30, 2011, 2010 and 2009 was $11.5 million, $10.2 million and $9.9 million, respectively.
Advertising Costs	Advertising Costs The Company defers advertising related costs until the advertising is first run in trade or other publications, or in the case of brochures, until the brochures are printed and available for distribution. Advertising costs, included in marketing costs, after vendor reimbursement, were not significant in any of the three years ended June 30, 2011. Deferred advertising costs at June 30, 2011 and 2010 were not significant.
Foreign Currency	Foreign Currency The currency effects of translating the financial statements of the Company's foreign entities that operate in their local currency are included in the cumulative currency translation adjustment component of accumulated other comprehensive loss income. The assets and liabilities of these foreign entities are translated into U.S. Dollars using the exchange rate at the end of the respective period. Sales, costs and expenses are translated at average exchange rates effective during the respective period. Foreign currency transactional and re-measurement gains and losses are included in other expense (income) in the Consolidated Income Statements. Such amounts are not significant to any of the periods presented.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred income taxes reflect tax consequences on future years of differences between the tax bases of assets and liabilities and their financial reporting amounts. Valuation allowances are provided against deferred tax assets in accordance with ASC 740, Accounting for Income Taxes. Federal income taxes are not assessed on the undistributed earnings of foreign subsidiaries because it has been the practice of the Company to reinvest those earnings in the business outside the United States. See Note 12 for further discussion. Additionally, The Company maintains reserves for uncertain tax provisions in accordance with ASC 740. See Note 12 for more information.
Share-Based Payments	Share-Based Payments The Company accounts for share-based compensation using the provisions of ASC 718, Accounting for Stock Compensation, which requires the recognition of the fair value of share-based compensation. Share-based compensation is estimated at the grant date based on the fair value of the awards, in accordance with the provisions of ASC 718. Since this compensation cost is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company has elected to expense grants of awards with graded vesting on a straight-line basis over the requisite service period for each separately vesting portion of the award.
Comprehensive Income	Comprehensive Income ASC 220, Reporting Comprehensive Income, defines comprehensive income as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The primary components of comprehensive income for the Company include net income, foreign currency translation adjustments arising from the consolidation of the Company's foreign subsidiaries, and unrealized gains and losses on the Company's hedged transactions, net of tax.
Business Combinations	Business Combinations The Company accounts for business combinations in accordance with ASC Topic 805, Business Combinations. ASC 805 establishes principles and requirements for recognizing the total consideration transferred to and the assets acquired, liabilities assumed and any non-controlling interest in the acquired target in a business combination. ASC 805 also provides guidance for recognizing and measuring goodwill acquired in a business combination and requires the acquirer to disclose information that users may need to evaluate and understand the financial impact of the business combination. See Note 5 for further discussion.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Credit Quality of Financing Receivables and the Allowance for Credit Losses In July 2010, the FASB issued Accounting Standard Update ("ASU") 2010-20 which updated the existing guidance regarding disclosures of financing receivables and the related allowance recorded against financing receivables, ASC 310. This revised guidance requires companies to disclose additional information in order to help financial statement users evaluate the following: 1) the nature of credit risk inherent in the entity's portfolio of financing receivables, 2) how that risk is analyzed and assessed in arriving at the allowance for credit losses and 3) the changes and reasons for those changes in the allowance for credit losses. This accounting update requires two types of disclosures: 1) disclosures as of the end of a reporting period and 2) disclosures about activity that occurs during a reporting period. Disclosures required as of the end of a reporting period are effective for interim and annual reporting periods ending on or after December 15, 2010. The Company adopted this guidance as it relates to period ending disclosures on October 1, 2010. The adoption of this guidance did not have an impact on the Company's Consolidated Financial Statements. Disclosures required about activity that occurs during a reporting period are effective for interim and annual reporting periods beginning on or after December 15, 2010. The Company adopted the guidance as it relates to periodic activity on January 1, 2011. The adoption of this guidance did not have an impact on the Company's Consolidated Financial Statements. Fair Value Measurement In May 2011, the FASB issued ASU 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS. The amendments in this update are the result of the work of the FASB and the IASB to develop common requirements for measuring fair value and for disclosing information about fair value measurements. The amendment becomes effective for interim and annual periods beginning after December 15, 2011, which will be the third quarter of fiscal 2012 for the Company. The Company is currently assessing the future impact of this ASU to its Consolidated Financial Statements. Comprehensive Income In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income. The objective of this update is to improve the comparability, consistency, and transparency of financial reporting and to increase the prominence of items reported in other comprehensive income. The update will become effective for interim and annual periods beginning after December 15, 2011, which will be the third quarter of fiscal 2012 for the Company. The update will eliminate the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity, which is the Company's current practice. Additionally, the update will require companies to present all nonowner changes in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The Company is currently determining which method of presentation will be used in future filings.
