Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited consolidated financial statements included herein have been prepared by Electro Rent Corporation, pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). The consolidated financial statements include the accounts of Electro Rent Corporation and its wholly owned subsidiaries, Electro Rent, LLC, ER International, Inc., Electro Rent Europe NV, Electro Rent Asia, Inc. and Electro Rent (Beijing) Test and Measurement Equipment Rental Co., Ltd. (collectively “we”, “us”, or “our”). All intercompany balances and transactions have been eliminated in consolidation. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted pursuant to such SEC rules and regulations. These unaudited consolidated financial statements reflect all adjustments, consisting of only normal recurring adjustments, and disclosures that are, in our opinion, necessary for a fair presentation of our financial position and results of operations for the interim periods presented. These unaudited consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in our latest Annual Report on Form 10-K filed with the SEC on August 13, 2015 . The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities as well as the disclosures of contingent assets and liabilities as of the date of these financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates, and results of operations for interim periods are not necessarily indicative of results to be expected for the full year. Revenue Recognition We generate revenues primarily through the rental and leasing of test and measurement equipment (“T&M”) and personal computer-related data products equipment (“DP”) and through the sale of new and used equipment. Rental revenues comprise short term agreements that can be daily, weekly or monthly. Rental revenues are recognized in the month they are due on the accrual basis of accounting. We lease equipment under both operating and finance lease agreements. Our operating lease agreements have varying terms, typically one to three years. Upon lease termination, customers have an option to renew the lease term, purchase the equipment at fair market value, or continue to rent on a month-to-month basis. Our operating leases do not provide for contingent rentals. Revenues related to operating leases are recognized on a straight-line basis over the term of the lease. Negotiated lease early-termination charges are recognized upon receipt. Rentals and leases are primarily billed to customers in advance, and unearned billings are recorded as deferred revenue. We enter into finance leases as lessor for some of our equipment. Our finance lease agreements contain bargain purchase options and are accounted for as sale-type leases. Revenues from finance leases, which are recorded at the present value of the aggregate future lease payments, net of unearned interest, are included in sales of equipment and other revenues in our consolidated statements of operations. Unearned interest is recognized over the life of the finance lease term using the effective interest method. Our finance lease terms vary and are typically one to three years. The net investment in finance leases, which represents the receivables due from lessees, net of unearned interest, is included in other assets in our consolidated balance sheets. Historically, we have not required security deposits based on our assessed credit risk within our customer base. Initial direct costs for operating and finance leases are insignificant. Sales of new equipment are recognized in the period in which the equipment is delivered and risk of loss passes to the customer, while sales of used equipment from our rental and lease equipment pool are recognized in the period in which the equipment is shipped and risk of loss passes to the customer. In the case of equipment sold to customers that is already on rent or on lease to the same party, revenue is recognized at the agreed-upon date when the rent or lease term ends and the risk of loss passes to the customer. The amount of revenue recognized for sales of new equipment depends on whether we sell as principal or as agent for the original equipment manufacturer. Prior to May 31, 2015 , our sales of new equipment were derived primarily from the reseller agreement with Keysight Technologies, Inc. In fiscal 2016, we entered into reseller agreements with other T&M equipment manufacturers, including Anritsu, Inc. ("Anritsu") and Rohde & Schwarz Gmbh & Co. KG ("Rohde & Schwarz"). Under the terms of these agreements we act as the principal with respect to sales of new equipment, based on several factors, including: (1) We act as the primary obligor by working directly with our customers to define their needs, providing them with options to satisfy such needs, contracting directly with the customer, and, to the extent required, providing customers with instruction on the use of the product and additional technical support once the product is received by the customer. The original equipment manufacturer is not a party to our customer sales agreements, nor is it referenced in the agreements, and therefore has no obligation to our customers with the exception of the manufacturer’s standard warranty on the product; (2) We bear back-end risk of inventory loss with respect to any product return from the customer as the original equipment manufacturer is not required to accept returns of equipment from us. Under the reseller agreement with Keysight, we also bore front-end risk of inventory loss in those cases where we acquired products for resale into our equipment pool prior to shipment to customers; (3) We have full discretion in setting pricing terms with our customers and negotiate all such terms ourselves; and (4) We assume all credit risk. In situations where we act as principal, the gross sales of new equipment are recorded in sales of equipment and other revenues, while the related equipment costs, including the purchase price from the original equipment manufacturer, are recorded in costs of sales of equipment and other revenues in our consolidated statements of operations. We are currently establishing new resale relationships, where we may act as an agent for the original equipment manufacturer. Under those arrangements, we recognize revenue only on the commissions that we receive, which are recorded in other revenue within the sales of equipment and other revenues in our consolidated statement of operations. Other revenues, which primarily include billings to customers for delivery and repairs, are recognized in the period in which the respective services are performed. Operating Expenses Costs of rentals and leases, excluding depreciation, primarily include labor related costs of our operations personnel, supplies, repairs, insurance and warehousing costs associated with our rental and lease equipment, relating to our rental and lease revenues. Costs of rentals and leases included impairment charges of $0 and $443 related to our T&M rental and lease equipment during the three and nine months ended February 29, 2016 . No impairments occurred for the three and nine months ended February 28, 2015 . Costs of sales of equipment and other revenues primarily include the cost of new equipment and the carrying value of used equipment sold. Selling, general and administrative (“SG&A”) expenses include sales and advertising costs, payroll and related benefit costs, insurance expenses, property taxes on our property and rental and lease equipment, legal and professional fees, and administrative overhead. Advertising costs are expensed as incurred. Total advertising expenses were $267 and $857 for the three and nine months ended February 29, 2016 and $301 and $720 for the three and nine months ended February 28, 2015 . SG&A expenses also included shipping and handling costs of $815 and $2,688 for the three and nine months ended February 29, 2016 and $847 and $2,968 for the three and nine months ended February 28, 2015 . Foreign Currency The U.S. dollar has been determined to be the functional currency of all foreign subsidiaries. The euro, British pound sterling, Canadian dollar and Chinese yuan are our primary foreign currencies. The assets and liabilities of our foreign subsidiaries are remeasured from their local currency to U.S. dollars at current or historic exchange rates, as appropriate. Revenues and expenses are remeasured from any foreign currencies to U.S. dollars using historic or average monthly exchange rates, as appropriate, for the month in which the transaction occurred. Remeasurement gains and losses are included in SG&A expenses or income taxes, as appropriate. The assets, liabilities, revenues and expenses of our foreign operations that are susceptible to foreign currency fluctuations are individually less than 10% of our respective consolidated amounts. Net remeasurement gains and losses have not been significant. We enter into forward contracts to hedge against unfavorable currency fluctuations in our monetary assets and liabilities in our European, Chinese and Canadian operations. These contracts are designed to minimize the effect of fluctuations in foreign currencies. To qualify for hedge accounting, contracts must reduce the foreign currency exchange rate and interest rate risk otherwise inherent in the amount and duration of the hedged exposures and comply with established risk management policies. Our derivative instruments are not designated as hedging instruments and, therefore, are recorded at fair value as an asset or liability, and any changes in fair value are recorded in our consolidated statements of operations. We do not use derivative financial instruments for speculative trading purposes. The fair values of our foreign exchange forward contracts in the consolidated balance sheets are shown in the table below: Derivatives Not Designated as Hedging Instruments Consolidated Balance Sheet Location February 29, 2016 May 31, 2015 Foreign exchange forward contracts Accrued Expenses $ (18 ) $ (16 ) The table below provides data about the amount of gains and losses recognized in income for derivative instruments not designated as hedging instruments: Derivatives Not Designated as Hedging Instruments Location of Gain/(Loss) Recognized in Income on Derivatives Three Months Ended February 29, 2016 Three Months Ended February 28, 2015 Foreign exchange forward contracts SG&A expenses $ (4 ) $ 149 Derivatives Not Designated as Hedging Instruments Location of Gain/(Loss) Recognized in Income on Derivatives Nine Months Ended February 29, 2016 Nine Months Ended February 28, 2015 Foreign exchange forward contracts SG&A expenses $ 201 $ 659 Other Assets We include demonstration equipment used in connection with our resale activity in other assets for a period of up to two years . Demonstration equipment is recorded at the lower of cost or estimated market value until the units are sold or transferred to our rental and lease equipment pool. Demonstration equipment transferred to our rental and lease equipment pool is depreciated over its remaining estimated useful life. We also have a Supplemental Executive Retirement Plan (“SERP”) that provides for automatic deferral of contributions in excess of the maximum amount permitted under the 401(k) for our executives who choose to participate. The SERP is a non-qualified deferred compensation program. We have the option to match contributions of participants at a rate we determine each year. Other assets consisted of the following: February 29, 2016 May 31, 2015 Income taxes receivable $ 7,213 $ — Demonstration equipment 5,207 81 Net investment in sales-type leases 3,700 5,876 Prepaid expenses and other 3,370 4,265 SERP 3,057 3,521 $ 22,547 $ 13,743 Recent Accounting Pronouncements In February 2016, the FASB issued guidance that will require lessees to put most leases on their balance sheets but recognize expenses in the income statement. For lessors, the standard will be similar to the current model but will be updated to align with certain changes to the lessee model. Lessors will continue to classify leases as operating, direct financing or sales-type leases. The standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The impact this guidance will have on the consolidated financial statements cannot be determined at this time. In May 2014, the Financial Accounting Standards Board and the International Accounting Standards Board issued guidance to establish a new, more robust framework for the recognition of revenue related to the transfer of goods and services to customers. This guidance is effective for reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The impact this guidance will have on the consolidated financial statements cannot be determined at this time. Other Comprehensive Income Comprehensive income is equivalent to net income for all periods presented. Out-of-period Adjustment During the second quarter of fiscal 2015, we identified $1.3 million of previously recognized revenue which the Company was not entitled to recognize. We determined this adjustment to be immaterial to our current and previously filed financial statements. We have recorded this out-of-period adjustment as a reduction to sales of equipment and other revenues and an increase to accrued expenses for the quarter ended November 30, 2014.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We measure certain financial assets and liabilities at fair value on a recurring basis, including SERP assets and liabilities, and foreign currency derivatives. The fair value of financial assets and liabilities can be determined based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, as follows: Level 1 – Observable inputs, such as quoted prices in active markets for identical assets or liabilities; Level 2 – Inputs, other than the quoted prices in active markets, that are observable either directly or through corroboration with observable market data; and Level 3 – Unobservable inputs, for which there is little or no market data for the assets or liabilities, such as those that may be used with internally-developed valuation models. Our assets and liabilities measured at fair value on a recurring basis were determined as follows: February 29, 2016 Quoted Prices in Active Markets for Identical Instruments (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Balance Assets SERP Money market fund $ 187 $ — $ — $ 187 Mutual funds 2,870 — — 2,870 Total assets measured at fair value $ 3,057 $ — $ — $ 3,057 Liabilities SERP $ 3,057 $ — $ — $ 3,057 Foreign exchange forward contracts — 18 — 18 Total liabilities measured at fair value $ 3,057 $ 18 $ — $ 3,075 May 31, 2015 Quoted Prices in Active Markets for Identical Instruments (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Balance Assets SERP Money market fund $ 166 $ — $ — $ 166 Mutual funds 3,355 — — 3,355 Total assets measured at fair value $ 3,521 $ — $ — $ 3,521 Liabilities SERP $ 3,521 $ — $ — $ 3,521 Foreign exchange forward contracts — 16 — 16 Total liabilities measured at fair value $ 3,521 $ 16 $ — $ 3,537 The fair value measures for our SERP assets and liabilities were derived from quoted market prices in active markets and are included in Level 1 inputs. Our SERP assets include money market and mutual funds, which we classify as trading securities. Foreign currency forward contracts were valued based on observable market spot and forward rates as of our reporting date and are included in Level 2 inputs.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity Incentive Plan	Equity Incentive Plan Our 2005 Equity Incentive Plan (the “Equity Incentive Plan”), as amended and restated, authorizes our Board of Directors to grant incentive and non-statutory stock option grants, stock appreciation rights, restricted stock awards, restricted stock units, performance unit awards and performance share awards covering a maximum of 1,000 shares of our common stock. Pursuant to the Equity Incentive Plan, we have granted restricted stock units to directors, officers and key employees. Restricted Stock Units Each vested restricted stock unit entitles the holder to be issued one share of common stock. The vested restricted stock units settle into common stock on the earliest of (i) the first January 1st after the fifth anniversary of the grant, (ii) a change of control, or (iii) termination of the holder’s employment or membership on our Board of Directors. Restricted stock units vest according to a vesting schedule determined by the Compensation Committee of our Board of Directors, generally over a one to three year period. The following table represents restricted stock unit activity for the nine months ended February 29, 2016 : Restricted Stock Units Weighted – Average Grant Date Fair Value Nonvested at June 1, 2015 129 $ 16.75 Granted 182 11.24 Vested (76 ) 16.08 Forfeited/canceled (7 ) 16.72 Nonvested at February 29, 2016 228 $ 12.59 We granted 182 and 87 restricted stock units during the nine months ended February 29, 2016 and February 28, 2015 , respectively. We did not grant any restricted stock units during the three months ended February 29, 2016 and February 28, 2015, respectively. Under the terms of our restricted stock unit agreements, nonvested restricted stock unit awards contain forfeitable rights to dividends. Because the dividends are forfeitable, the restricted stock units are defined as non-participating securities. As of February 29, 2016 , we have unrecognized share-based compensation cost of approximately $2,119 associated with restricted stock unit awards. This cost is expected to be recognized over a weighted-average period of approximately 2.0 years . We had 232 and 401 vested restricted stock units outstanding as of February 29, 2016 and February 28, 2015 , respectively, which receive dividends following vesting and are convertible to common shares five years after the grant date. Accounting for Share-Based Payments Accounting guidance requires all share-based payments to employees, including grants of restricted stock units, to be recognized as compensation expense in the consolidated financial statements based on their fair values. Compensation expense is recognized over the period that an employee provides service in exchange for the award, which is approximately three years . Forfeitures are estimated at the date of grant based on historical experience. We use the market price of our common stock on the date of grant to calculate the fair value of each grant of restricted stock units. We recorded $368 and $1,016 of share-based compensation as part of SG&A expenses for the three and nine months ended February 29, 2016 and $319 and $968 for the three and nine months ended February 28, 2015 . We receive a tax deduction for certain restricted stock units on the date the related shares are issued, generally for (1) the fair value of our common stock at the date of issuance and (2) for dividends paid on vested restricted stock units where the underlying shares have not been issued. Excess tax benefits are realized when restricted stock units are issued and the tax deductions (fair value at issuance) are greater than the compensation expense for financial reporting purposes (fair value at the date of grant). Shortfalls are realized when the fair value at issuance is less than the fair value at grant. For the nine months ended February 29, 2016 and February 28, 2015 , we realized a total excess tax shortfall of $40 and an excess tax benefit of $348 , respectively.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Intangible assets resulting from the acquisitions of entities accounted for using the acquisition method of accounting are recorded at the estimated fair value of the assets acquired. Identifiable intangible assets consist of purchased customer relationships and trade names. Our goodwill and intangibles at February 29, 2016 are the result of our acquisition of Equipment Management Technology, Inc. on August 24, 2011, Telogy LLC on March 31, 2010, and Rush Computer Rentals, Inc. on January 31, 2006. The changes in carrying amount of goodwill and other intangible assets for the nine months ended February 29, 2016 were as follows: Balance as of June 1, 2015 (net of amortization) Additions Amortization Balance as of February 29, 2016 Goodwill $ 3,109 $ — $ — $ 3,109 Trade name 411 — — 411 Customer relationships 333 — (88 ) 245 $ 3,853 $ — $ (88 ) $ 3,765 Goodwill is not deductible for tax purposes. We evaluate the recoverability of goodwill and indefinite-lived intangible assets annually as of May 31, and whenever events or changes in circumstances indicate to us that the carrying amount may not be recoverable. There were no conditions that indicated any impairment of goodwill or identifiable intangible assets as of February 29, 2016 and May 31, 2015 . Intangible assets with finite useful lives are amortized over their respective estimated useful lives.

Borrowings	Borrowings On November 19, 2013, we entered into a credit agreement (the “Credit Agreement”) with J.P. Morgan Chase Bank, National Association (“JPM”), as administrative agent, J.P. Morgan Securities LLC, as sole bookrunner and sole lead arranger, and a syndicate of lenders. The Credit Agreement provides for a $25,000 revolving credit facility, including swingline loans and letters of credit. The Credit Agreement expires on November 30, 2017 . We have an option to increase the commitments under the Credit Agreement by up to an additional $25,000 , upon our request and subject to the lenders electing to increase their commitments or by means of the addition of new lenders. Borrowings under the Credit Agreement bear interest at a rate equal to, at our election, the applicable rate for a “Eurodollar Loan” or a “CB Floating Rate Loan.” Eurodollar Loan advances accrue interest at a per annum interest rate equal to (i) the quotient (rounded upwards to the next 1/16th of 1%) of (a) the applicable LIBO Rate, divided by (b) one minus the maximum aggregate reserve requirement (expressed as a decimal) imposed under Federal Reserve Board Regulation D (the “Adjusted LIBO Rate”), plus (ii) 0.75% . CB Floating Rate Loan advances accrue interest at a per annum interest rate equal to (i) the higher of (a) JPM’s Prime Rate or (b) the Adjusted LIBO Rate for a one month interest period plus 2.5% , minus (ii) 2.0% . In addition, we pay a commitment fee of 0.10% of the unused amount if the average borrowing under the Credit Agreement is less than or equal to $8,000 on a quarterly basis. The Credit Agreement contains customary affirmative and negative covenants (which are in some cases subject to certain exceptions), including, but not limited to, restrictions on the ability to incur additional indebtedness, create liens, make certain investments, make restricted payments, enter into or undertake certain liquidations, mergers, consolidations or acquisitions and dispose of assets or subsidiaries. In addition, the Credit Agreement requires us to maintain minimum earnings and tangible net worth. We were in compliance with all financial covenants at February 29, 2016 . We had no borrowings outstanding under the Credit Agreement at February 29, 2016 and $2,387 of borrowings outstanding at May 31, 2015. The weighted average interest rate under the line of credit was approximately 1.25% at May 31, 2015.

Leases [Abstract]
Sales-Type Leases	Sales-Type Leases We have certain customer leases providing bargain purchase options, which are accounted for as sales-type leases. Interest income is recognized over the life of the lease using the effective interest method. The initial acceptance of customer finance arrangements is based on a review of each customer’s credit profile, which may include the review of third party credit reports, customer financial statements and/or bank verifications. We monitor the credit quality of our sales-type lease portfolio based on payment activity and the related finance lease receivable aging. This credit quality is assessed on a monthly basis. Our historical losses on finance lease receivables are insignificant, and therefore we do not have a specific allowance for credit losses. The minimum lease payments receivable and the net investment included in other assets for such leases were as follows: February 29, 2016 May 31, 2015 Gross minimum lease payments receivable $ 3,824 $ 6,109 Less – unearned interest (124 ) (233 ) Net investment in sales-type lease receivables $ 3,700 $ 5,876 The following table provides estimated future minimum lease payments by year related to sales-type leases: Year ending May 31, Future Payments 2016 (remaining) $ 1,084 2017 2,360 2018 363 2019 17 2020 — $ 3,824

Segment Reporting [Abstract]
Segment Reporting and Related Disclosures	Segment Reporting and Related Disclosures Accounting guidance establishes reporting standards for an enterprise’s operating segments and related disclosures about its products, services, geographic areas and major customers. Operating segments are defined as components of an enterprise for which separate financial information is available and is regularly evaluated by the chief operating decision maker in deciding how to allocate resources and in assessing performance. In order to determine our operating segments, we considered the following: an operating segment is a component of an enterprise (i) that engages in business activities from which it may earn revenues and incur expenses, (ii) whose operating results are regularly reviewed by the enterprise’s chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance, and (iii) for which discrete financial information is available. In accordance with this guidance, we have identified two operating segments in our business: our T&M and DP businesses. In the past, we concluded that although we had separate operating segments for T&M and DP equipment, these two segments could be aggregated into a single reportable segment because they had similar economic characteristics and qualitative factors. However, as a result of a change in economic characteristics in fiscal 2015 in our T&M segment, primarily attributable to the expiration of the Keysight reseller agreement and greater competition in the marketplace, we concluded that we no longer expected similar economic characteristics and qualitative factors to continue in the future. As such, management determined that the operating segments should no longer be aggregated. Following the change in the composition of our reportable operating segments, we restated the segment information for fiscal 2015. Our equipment pool, based on acquisition cost, consisted of $409,310 of T&M equipment and $32,656 of DP equipment at February 29, 2016 and $434,963 of T&M equipment and $37,824 of DP equipment at May 31, 2015 . Additional segment asset information is not available. Revenues for these operating segments were as follows for the three months ended February 29, 2016 and February 28, 2015 : T&M DP Total 2016 Rentals and leases $ 25,340 $ 3,833 $ 29,173 Sales of equipment and other revenues 9,857 468 10,325 Segment and consolidated total $ 35,197 $ 4,301 $ 39,498 2015 Rentals and leases $ 26,372 $ 3,880 $ 30,252 Sales of equipment and other revenues 25,799 291 26,090 Segment and consolidated total $ 52,171 $ 4,171 $ 56,342 Revenues for these operating segments were as follows for the nine months ended February 29, 2016 and February 28, 2015 : T&M DP Total 2016 Rentals and leases $ 79,937 $ 13,712 $ 93,649 Sales of equipment and other revenues 40,888 1,614 42,502 Segment and consolidated total $ 120,825 $ 15,326 $ 136,151 2015 Rentals and leases $ 84,410 $ 13,200 $ 97,610 Sales of equipment and other revenues 79,033 1,273 80,306 Segment and consolidated total $ 163,443 $ 14,473 $ 177,916 Depreciation of rental and lease equipment for these operating segments was as follows for the three and nine months ended February 29, 2016 and February 28, 2015 : Three Months Ended February 29, 2016 February 28, 2015 T&M $ 12,699 $ 12,856 DP 1,045 988 Segment and consolidated total $ 13,744 $ 13,844 Nine Months Ended February 29, 2016 February 28, 2015 T&M $ 39,388 $ 39,387 DP 3,297 3,042 Segment and consolidated total $ 42,685 $ 42,429 Amortization expense is not material and is included in SG&A expenses.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We recognize a liability or asset for the deferred tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements. These temporary differences will result in taxable or deductible amounts in future years when reported amounts of the assets or liabilities are recovered or settled. The deferred tax assets are periodically reviewed for recoverability. Accounting guidance for uncertain tax positions prescribes a recognition threshold that a tax position is required to meet before being recognized in the financial statements and provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition issues. We recognize the tax impact from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax impact recognized in the financial statements from such a position is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. We recognize interest, penalties and foreign currency gains and losses with respect to uncertain tax positions as components of our income tax provision. Accrued interest and penalties are included within accrued expenses in the consolidated balance sheet. Significant judgment is required in the identification of uncertain tax positions and in the estimation of related penalties and interest. There were no uncertain tax positions in fiscal 2016 and 2015 . We are subject to taxation in the U.S., as well as various state and foreign jurisdictions. We have substantially settled all income tax matters for the United States federal jurisdiction for years through fiscal 2011. Major state jurisdictions have been examined through fiscal years 2004 and 2005, and foreign jurisdictions have not been examined for their respective initial statutory periods of approximately 3 years.

Commitments and Contingencies	Commitments and Contingencies We are subject to legal proceedings and business disputes involving ordinary routine legal proceedings and claims incidental to our business. The ultimate legal and financial liability with respect to such matters generally cannot be estimated with certainty and requires the use of estimates in recording liabilities for potential litigation settlements or awards against us. Estimates for losses from litigation are made after consultation with outside counsel. If estimates of potential losses increase or the related facts and circumstances change in the future, we may be required to record either more or less litigation expense. We are not involved in any pending or threatened legal proceedings that we believe would reasonably be expected to have a material adverse effect on our financial condition, results of operations or cash flows.

Accounting Policies [Abstract]
Revenue Recognition	Revenue Recognition We generate revenues primarily through the rental and leasing of test and measurement equipment (“T&M”) and personal computer-related data products equipment (“DP”) and through the sale of new and used equipment. Rental revenues comprise short term agreements that can be daily, weekly or monthly. Rental revenues are recognized in the month they are due on the accrual basis of accounting. We lease equipment under both operating and finance lease agreements. Our operating lease agreements have varying terms, typically one to three years. Upon lease termination, customers have an option to renew the lease term, purchase the equipment at fair market value, or continue to rent on a month-to-month basis. Our operating leases do not provide for contingent rentals. Revenues related to operating leases are recognized on a straight-line basis over the term of the lease. Negotiated lease early-termination charges are recognized upon receipt. Rentals and leases are primarily billed to customers in advance, and unearned billings are recorded as deferred revenue. We enter into finance leases as lessor for some of our equipment. Our finance lease agreements contain bargain purchase options and are accounted for as sale-type leases. Revenues from finance leases, which are recorded at the present value of the aggregate future lease payments, net of unearned interest, are included in sales of equipment and other revenues in our consolidated statements of operations. Unearned interest is recognized over the life of the finance lease term using the effective interest method. Our finance lease terms vary and are typically one to three years. The net investment in finance leases, which represents the receivables due from lessees, net of unearned interest, is included in other assets in our consolidated balance sheets. Historically, we have not required security deposits based on our assessed credit risk within our customer base. Initial direct costs for operating and finance leases are insignificant. Sales of new equipment are recognized in the period in which the equipment is delivered and risk of loss passes to the customer, while sales of used equipment from our rental and lease equipment pool are recognized in the period in which the equipment is shipped and risk of loss passes to the customer. In the case of equipment sold to customers that is already on rent or on lease to the same party, revenue is recognized at the agreed-upon date when the rent or lease term ends and the risk of loss passes to the customer. The amount of revenue recognized for sales of new equipment depends on whether we sell as principal or as agent for the original equipment manufacturer. Prior to May 31, 2015 , our sales of new equipment were derived primarily from the reseller agreement with Keysight Technologies, Inc. In fiscal 2016, we entered into reseller agreements with other T&M equipment manufacturers, including Anritsu, Inc. ("Anritsu") and Rohde & Schwarz Gmbh & Co. KG ("Rohde & Schwarz"). Under the terms of these agreements we act as the principal with respect to sales of new equipment, based on several factors, including: (1) We act as the primary obligor by working directly with our customers to define their needs, providing them with options to satisfy such needs, contracting directly with the customer, and, to the extent required, providing customers with instruction on the use of the product and additional technical support once the product is received by the customer. The original equipment manufacturer is not a party to our customer sales agreements, nor is it referenced in the agreements, and therefore has no obligation to our customers with the exception of the manufacturer’s standard warranty on the product; (2) We bear back-end risk of inventory loss with respect to any product return from the customer as the original equipment manufacturer is not required to accept returns of equipment from us. Under the reseller agreement with Keysight, we also bore front-end risk of inventory loss in those cases where we acquired products for resale into our equipment pool prior to shipment to customers; (3) We have full discretion in setting pricing terms with our customers and negotiate all such terms ourselves; and (4) We assume all credit risk. In situations where we act as principal, the gross sales of new equipment are recorded in sales of equipment and other revenues, while the related equipment costs, including the purchase price from the original equipment manufacturer, are recorded in costs of sales of equipment and other revenues in our consolidated statements of operations. We are currently establishing new resale relationships, where we may act as an agent for the original equipment manufacturer. Under those arrangements, we recognize revenue only on the commissions that we receive, which are recorded in other revenue within the sales of equipment and other revenues in our consolidated statement of operations. Other revenues, which primarily include billings to customers for delivery and repairs, are recognized in the period in which the respective services are performed.
Operating expenses	Operating Expenses Costs of rentals and leases, excluding depreciation, primarily include labor related costs of our operations personnel, supplies, repairs, insurance and warehousing costs associated with our rental and lease equipment, relating to our rental and lease revenues. Costs of rentals and leases included impairment charges of $0 and $443 related to our T&M rental and lease equipment during the three and nine months ended February 29, 2016 . No impairments occurred for the three and nine months ended February 28, 2015 . Costs of sales of equipment and other revenues primarily include the cost of new equipment and the carrying value of used equipment sold. Selling, general and administrative (“SG&A”) expenses include sales and advertising costs, payroll and related benefit costs, insurance expenses, property taxes on our property and rental and lease equipment, legal and professional fees, and administrative overhead. Advertising costs are expensed as incurred.
Foreign Currency	Foreign Currency The U.S. dollar has been determined to be the functional currency of all foreign subsidiaries. The euro, British pound sterling, Canadian dollar and Chinese yuan are our primary foreign currencies. The assets and liabilities of our foreign subsidiaries are remeasured from their local currency to U.S. dollars at current or historic exchange rates, as appropriate. Revenues and expenses are remeasured from any foreign currencies to U.S. dollars using historic or average monthly exchange rates, as appropriate, for the month in which the transaction occurred. Remeasurement gains and losses are included in SG&A expenses or income taxes, as appropriate. The assets, liabilities, revenues and expenses of our foreign operations that are susceptible to foreign currency fluctuations are individually less than 10% of our respective consolidated amounts. Net remeasurement gains and losses have not been significant. We enter into forward contracts to hedge against unfavorable currency fluctuations in our monetary assets and liabilities in our European, Chinese and Canadian operations. These contracts are designed to minimize the effect of fluctuations in foreign currencies. To qualify for hedge accounting, contracts must reduce the foreign currency exchange rate and interest rate risk otherwise inherent in the amount and duration of the hedged exposures and comply with established risk management policies. Our derivative instruments are not designated as hedging instruments and, therefore, are recorded at fair value as an asset or liability, and any changes in fair value are recorded in our consolidated statements of operations. We do not use derivative financial instruments for speculative trading purposes.
Other Assets	Other Assets We include demonstration equipment used in connection with our resale activity in other assets for a period of up to two years . Demonstration equipment is recorded at the lower of cost or estimated market value until the units are sold or transferred to our rental and lease equipment pool. Demonstration equipment transferred to our rental and lease equipment pool is depreciated over its remaining estimated useful life. We also have a Supplemental Executive Retirement Plan (“SERP”) that provides for automatic deferral of contributions in excess of the maximum amount permitted under the 401(k) for our executives who choose to participate. The SERP is a non-qualified deferred compensation program. We have the option to match contributions of participants at a rate we determine each year.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2016, the FASB issued guidance that will require lessees to put most leases on their balance sheets but recognize expenses in the income statement. For lessors, the standard will be similar to the current model but will be updated to align with certain changes to the lessee model. Lessors will continue to classify leases as operating, direct financing or sales-type leases. The standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The impact this guidance will have on the consolidated financial statements cannot be determined at this time. In May 2014, the Financial Accounting Standards Board and the International Accounting Standards Board issued guidance to establish a new, more robust framework for the recognition of revenue related to the transfer of goods and services to customers. This guidance is effective for reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The impact this guidance will have on the consolidated financial statements cannot be determined at this time.
