Business and Summary of Significant Accounting Policies	Business and Summary of Significant Accounting Policies Business Description ScanSource, Inc. (together with its subsidiaries referred to as “the Company” or “ScanSource”) is at the center of the solution delivery channel, connecting businesses and institutions, and providing technology solutions. The Company brings technology solutions and services from the world’s leading suppliers of point-of-sale (POS), payments, barcode, physical security, unified communications and collaboration, and telecom and cloud services to market. The Company operates in the United States, Canada, Latin America and Europe. The Company's two operating segments, Worldwide Barcode, Networking & Security and Worldwide Communications & Services, are based on product, customer and service type. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared by the Company’s management in accordance with United States generally accepted accounting principles ("U.S. GAAP") for interim financial information and applicable rules and regulations of the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for annual financial statements. The unaudited condensed consolidated financial statements included herein contain all adjustments (consisting of normal recurring and non-recurring adjustments) that are, in the opinion of management, necessary to present fairly the financial position as of March 31, 2019 and June 30, 2018, the results of operations for the quarters and nine months ended March 31, 2019 and 2018, the statements of comprehensive income for the quarters and nine months ended March 31, 2019 and 2018, the statements of shareholders' equity for the quarters and nine months ended March 31, 2019 and 2018 and the statements of cash flows for the nine months ended March 31, 2019 and 2018. The results of operations for the quarters and nine months ended March 31, 2019 and 2018 are not necessarily indicative of the results to be expected for a full year. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2018. Summary of Significant Accounting Policies Except as described below, there have been no material changes to the Company’s significant accounting policies for the nine months ended March 31, 2019 from the policies described in the notes to the Company’s consolidated financial statements included in the Annual Report on Form 10-K for the fiscal year ended June 30, 2018. For a discussion of the Company’s significant accounting policies, please see the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2018. Cash and Cash Equivalents The Company considers all highly-liquid investments with original maturities of three months or less, when purchased, to be cash equivalents. The Company maintains zero-balance disbursement accounts at various financial institutions at which the Company does not maintain significant depository relationships. Due to the terms of the agreements governing these accounts, the Company generally does not have the right to offset outstanding checks written from these accounts against cash on hand, and the respective institutions are not legally obligated to honor the checks until sufficient funds are transferred to fund the checks. As a result, checks released but not yet cleared from these accounts in the amounts of $16.8 million and $5.7 million are included in accounts payable as of March 31, 2019 and June 30, 2018, respectively. Long-lived Assets The Company presents depreciation expense and intangible amortization expense individually on the Condensed Consolidated Income Statements. The Company's depreciation expense related to selling, general and administrative costs totaled $3.4 million and $10.0 million for the quarter and nine months ended March 31, 2019, respectively, and $3.4 million and $10.1 million for the quarter and nine months ended March 31, 2018, respectively. Depreciation expense reported as part of cost of goods sold on the Condensed Consolidated Income Statements totaled $0.9 million and $2.9 million for the quarter and nine months ended March 31, 2019, respectively, and $1.0 million and $2.5 million for the quarter and nine months ended March 31, 2018, respectively. The Company's amortization expense reported on the Condensed Consolidated Income Statements relates to selling, general and administrative costs, not the cost of selling goods. Intangible amortization expense totaled $5.0 million and $14.7 million for the quarter and nine months ended March 31, 2019, respectively, and $5.1 million and $15.6 million for the quarter and nine months ended March 31, 2018, respectively. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued a comprehensive new revenue recognition standard for contracts with customers that superseded the most current revenue recognition guidance, including industry-specific guidance under Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606). In March, April, May and December 2016 the FASB issued additional ASUs to provide supplemental adoption guidance and clarification to ASU 2014-09. The core principle of this standard is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this core principle, the standard provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include the capitalization and amortization of certain contract costs, ensuring the time value of money is considered in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. This guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. The Company adopted the standard on July 1, 2018 using the full retrospective method. The adoption of this standard had no material impact on the Company's consolidated financial statements. See Note 2 Revenue Recognition for additional information. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) requiring lessees to reflect most leases on their balance sheets and recognize expenses on their income statements in a manner similar to current guidance. Under the new guidance, lessees will be required to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The asset will be measured at the lease liability amount, adjusted for lease prepayments, lease incentives received and the lessee's initial direct costs. For leases with a lease term of 12 months or less, as long as the lease does not include options to purchase the underlying assets, lessees can elect not to recognize a lease liability and right-of-use asset. Under the new guidance, lessor accounting is largely unchanged, and the accounting for sale and leaseback transactions is simplified. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. This guidance will be applicable to the Company for the fiscal year beginning July 1, 2019. The guidance can be adopted using a modified retrospective approach or a cumulative-effect adjustment to the opening balance sheet of retained earnings in the period of adoption for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company has established a lease implementation team and is in the process of reviewing leases to determine an implementation approach. Currently, the Company is evaluating the impact on its consolidated financial statements upon the adoption of this new guidance. In June 2016, the FASB issues ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326: Financial Instruments - Credit Losses, which provides supplemental guidance and clarification to ASU 2016-13 and must be adopted concurrently. The pronouncement revises the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. The guidance is effective for the Company beginning in the first quarter of fiscal year 2021 with early adoption permitted. The Company is currently evaluating the potential impact of this guidance on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) intended to reduce diversity in practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The update addresses eight specific cash flow issues, with the treatment of contingent consideration payments made after a business combination being the most directly applicable to the Company. The update requires that cash payments made approximately three months or less after an acquisition's consummation date should be classified as cash outflows for investing activities. Payment made thereafter up to the amount of the original contingent consideration liability should be classified as cash outflows from financing activities. Payments made in excess of the amount of the original contingent consideration liability should be classified as cash outflows from operating activities. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company adopted the standard for the fiscal year beginning July 1, 2018 using the retrospective transition method. For fiscal year 2018, the Company classified the amount of the Network1 earnout payment paid in excess of the originally anticipated liability at the acquisition date as an operating cash outflow. For fiscal year 2019, the Company classified the amounts of the Intelisys and Network1 earnout payments in excess as an operating cash outflow. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815) that amends and simplifies guidance related to hedge accounting to more accurately portray the economics of an entity’s risk management activities in its financial statements. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted in any interim or annual period. This guidance will be applicable to the Company for the fiscal year beginning July 1, 2019. The guidance requires adoption using a modified retrospective approach. The presentation and disclosure requirements apply prospectively. The Company is currently evaluating the impact on its consolidated financial statements upon the adoption of this new guidance. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The pronouncement eliminates, modifies and adds disclosure requirements for fair value measurements. This guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years, with early adoption permitted. This guidance is applicable to the Company’s fiscal year beginning July 1, 2020. The Company is currently evaluating the potential impact of this guidance on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. This ASU amends the definition of a hosting arrangement and requires a customer in a hosting arrangement that is a service contract to capitalize certain implementation costs as if the arrangement was an internal-use software project. Under this ASU, a customer will determine whether to capitalize implementation costs of the cloud computing arrangement that is a service contract or expense them as incurred. This guidance is applicable to the Company’s fiscal year beginning July 1, 2020, with early adoption permitted. The Company is currently evaluating the potential impact of this guidance on its consolidated financial statements. In August 2018, the SEC adopted a final rule that amends certain of its disclosure requirements. The rule requires registrants to include in the interim financial reporting an analysis of changes in shareholders' equity for the current and comparative year-to-date interim periods. The final rule was effective on November 5, 2018 with registrants required to provide interim reporting in the first period beginning after the effective date. The Company provided an interim analysis of changes in shareholders' equity for the quarter ending March 31, 2019 in this Form 10-Q. The Company has reviewed other newly issued accounting pronouncements and concluded that they are either not applicable to its business or that no material effect is expected on its consolidated financial statements as a result of future adoption. Reclassifications Certain reclassifications have been made on the Consolidated Statements of Cash Flows to classify contingent consideration payments made in excess of the original contingent liability as an operating activity in accordance with ASU 2016-15. These reclassifications had no effect on consolidated financial results.
