Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	The accompanying condensed consolidated financial statements of the Company and its wholly-owned subsidiaries are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America are not required in these interim financial statements and have been condensed or omitted. All significant intercompany accounts and transactions have been eliminated in consolidation.
New Accounting Pronouncements	Recent Accounting Pronouncements Public companies in the United States are subject to the accounting and reporting requirements of various authorities, including the Financial Accounting Standards Board (“FASB”) and the Securities and Exchange Commission (“SEC”). These authorities issue numerous pronouncements, most of which are not applicable to the Company’s current or reasonably foreseeable operating structure. In May 2014, the Financial Accounting Standards Board (FASB) issued a new accounting standard that amends the guidance for the recognition of revenue from contracts with customers to transfer goods and services. The new revenue recognition standard is effective for interim and annual periods beginning on January 1, 2018. The new standard is required to be adopted using either a full-retrospective or a modified-retrospective approach. The Company adopted the new standard using the modified-retrospective approach beginning on January 1, 2018. There was no material impact to total revenues in our consolidated statements of income, accounting policies, business processes, internal controls or disclosures. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 related to leases that outlines a comprehensive lease accounting model and supersedes the current lease guidance. The new guidance requires lessees to recognize lease liabilities and corresponding right-of-use assets for all leases with lease terms of greater than 12 months. It also changes the definition of a lease and expands the disclosure requirements of lease arrangements. The new guidance must be adopted using the modified retrospective approach and will be effective for the Company starting in the first quarter of fiscal 2019. Early adoption is permitted. The Company is currently in the process of evaluating the impact of the adoption of this standard on the consolidated financial statements. In March 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other: Simplifying the Test for Goodwill Impairment. which eliminates the second step from the goodwill impairment test. An entity should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity will recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, but the loss cannot exceed the total amount of goodwill allocated to the reporting unit. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. The Company is evaluating the effect of adopting this pronouncement.
Revenue	The Company’s revenue is primarily comprised of sales of maintenance, repair and operational (“MRO”) products that are sold by IPG and information and communications technology (“ICT”) products that are sold by ETG. Additionally, both IPG and ETG have revenues from related activities, such as freight and, to a lesser extent, services. The Company recognizes revenue when a sales arrangement with a customer exists through the Company’s invoicing or a contract, the performance obligations have been identified, the transaction price is fixed or determinable and the Company has satisfied its performance obligations. The Company’s standard terms, provided on its invoices as well as on its websites, are included in communications with the customer and have standard payment terms of 30 days. Certain customers may have extended payment terms that have been pre-approved by the Company’s credit department, but none extend longer than 90 days. The Company’s performance obligation is primarily a single obligation to deliver products. The Company’s performance obligations are satisfied when products are transferred to a customer in accordance with agreed upon shipping terms. Certain sales may include product and/or services that are distinct and accounted for as separate performance obligations. The Company’s performance obligations for services are satisfied when the services are rendered. The Company’s total service revenue is immaterial as it accounted for less than 1% of total revenue for the first quarter of 2018. The Company’s revenue is shown as “Net sales” in the accompanying Condensed Statements of Operations and is measured as the determined transaction price, net of any variable consideration primarily rights to return product. The Company has elected to treat shipping and handling revenues as activities to fulfill its performance obligation. Billings for freight and shipping and handling are recorded in net sales and costs of freight and shipping and handling are recorded in cost of sales in the accompanying Condensed Consolidated Statements of Operations. The Company records a contract liability in cases where customers pay in advance of the Company satisfying its performance obligation. The Company did not have any material unsatisfied performance obligations or liabilities as of March 31, 2018. The Company offers customers rights to return product within a certain time, usually 30 days. The Company estimates is sales returns liability quarterly based upon its historical returns rates as a percentage of historical sales for the trailing twelve-month period.
