Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Liquidity Services, Inc. (the “Company”) operates a network of ecommerce marketplaces that enable buyers and sellers to transact in an efficient, automated environment. The Company’s marketplaces provide professional buyers access to a global, organized supply of new, surplus, and scrap assets presented with digital images and other relevant product information. Additionally, the Company enables its corporate and government sellers to enhance their financial return on offered assets by providing a liquid marketplace and value-added services that encompass the consultative management, valuation, and sale of surplus assets. The Company provides fully-managed services that include program management, valuation, asset management, reconciliation, returns process management, refurbishment and recycling, fulfillment, marketing and sales, warehousing and transportation, buyer support, compliance and risk mitigation, as well as self-directed service offerings. The Company organizes the products on its marketplaces into categories across major industry verticals such as consumer electronics, general merchandise, apparel, scientific equipment, aerospace parts and equipment, technology hardware, energy equipment, industrial capital assets, fleet and transportation equipment and specialty equipment. The Company’s marketplaces are: www.liquidation.com, www.direct.liquidation.com, www.govdeals.com, www.networkintl.com, www.secondipity.com, www.go-dove.com, and www.auctiondeals.com. The Company also operates a global search engine for listing used machinery and equipment for sale at www.machinio.com. The Company has four reportable segments, Retail Supply Chain Group (RSCG), Capital Assets Group (CAG), GovDeals and Machinio. See Note 13 in the Notes to the Consolidated Financial Statements for Segment Information. On July 10, 2018, the Company acquired 100% of Machinio Corp.("Machinio"), a privately-owned company based in Chicago, Illinois, with a second office in Berlin, Germany. Machinio operates a global online platform for listing used equipment for sale in the construction, machine tool, transportation, printing and agriculture sectors. The consideration paid to the sellers was approximately $16.7 million in net cash, equity consideration of approximately $2.0 million, and contingent consideration payable in 2020 in an amount up to $5.0 million. The Company's operations are subject to certain risks and uncertainties, many of which are associated with technology-oriented companies, including, but not limited to, the Company's dependence on use of the Internet, the effect of general business and economic trends, the Company's susceptibility to rapid technological change, actual and potential competition by entities with greater financial and other resources, and the potential for the commercial sellers from which the Company derives a significant portion of its inventory to change the way they conduct their disposition of surplus assets or to otherwise terminate or not renew their contracts with the Company.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Unaudited Interim Financial Information

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal, recurring adjustments considered necessary for a fair presentation have been included. The information disclosed in the notes to the consolidated financial statements for these periods is unaudited. Operating results for the three and six months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending September 30, 2019 or for any future period.

In the Consolidated Statements of Operations, revenue from the resale of inventory that the Company purchases from sellers is recognized within “Revenue”. Commission fees from the sale of inventory that the Company sells on a consignment basis and other non-consignment fee revenue, which is made up of subscription fee and service revenue from the Surplus contract in the prior year, is recognized within “Fee Revenue”.

Revenue Recognition

The Company adopted Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customers ("ASC 606") effective October 1, 2018. As a result of adopting ASC 606, there have been significant changes to the Company's revenue recognition policy from the policy disclosed in Note 2-Summary of Significant Accounting Polices in the Company’s Annual Report on Form 10-K for the year ended September 30, 2018. These changes are described below.

The Company recognizes revenue when or as performance obligations are satisfied and control is transferred to the customer. Revenue will be recognized in the amount that reflects the consideration to which the Company expects to be entitled.

Revenue is also evaluated to determine whether the Company should report the gross proceeds as revenue (when the Company acts as the principal in the arrangement) or the Company should report its revenue on a net basis (when the Company acts as an agent). Specifically, when other parties are involved in providing goods or services to an entity’s customer, the Company must determine whether the nature of its promise is a performance obligation to provide the specified goods or services itself, or to arrange for another party to provide them. The Company evaluates the following factors to determine if it is acting as a principal: (1) whether the Company is primarily responsible for fulfilling the promise to provide the asset or assets; (2) whether the Company has inventory risk of the asset or assets before they are transferred to the Buyer; and (3) whether the Company has discretion in establishing the price for the asset or assets.

The Company enters into contracts with Buyers and Sellers. The Company has master agreements with some Sellers pertaining to the sale of a flow of surplus assets over the term of the master agreement, however; a contract for accounting purposes exists when the Company agrees to sell a specific asset or assets. When acting as a principal (a “principal” arrangement), the Company purchases an asset or assets from a Seller and the Company has a performance obligation to sell the asset or assets to a Buyer. For principal arrangements, the Company recognizes as revenue the gross proceeds from the sale, including buyer's premiums, within Revenue. Also, when acting as a principal, the contract with the Seller is not a contract in the scope of the revenue recognition guidance; rather, it is a purchase of inventory. When the Company is acting as an agent (a “consignment” arrangement), its performance obligation is to arrange for the Seller to sell an asset or assets to the Buyer directly. The Company recognizes revenue within Fee Revenue based on the sales commissions that are paid to the Company by the sellers for utilizing the Company's services; in this situation, sales commissions represent a percentage of the gross proceeds from the sale that the seller pays to the Company upon completion of the transaction.

In both principal and consignment contracts, the Company sometimes provides distinct services to the Seller, such as returns management or refurbishment of assets. These services are distinct because the Seller could benefit from the services separately from the asset sale, and as such they are treated as separate performance obligations. Some services provided to Sellers are not distinct, like providing access to the Company’s ecommerce marketplaces or promoting the asset or assets for sale, because they could not benefit the Seller separately from the sale of the asset or assets.

The consideration received from Buyers and Sellers includes (1) buyer’s premiums, (2) seller’s commissions, and (3) fees for services, including reimbursed expenses. Consideration is variable based on units, final auction prices, or other factors, until the Buyer’s purchase of the asset or assets is complete, or the service has been provided. Recognition of variable consideration that is based on the results of auctions or purchases by Buyers is constrained until those transactions have been finalized. The Company estimates and recognizes amounts related to sales returns, discounts or rebates promised to customers, and reimbursed expenses. The total transaction price is allocated to each distinct performance obligation and revenue is recognized when or as the performance obligation is satisfied. Variable consideration is allocated to individual performance obligations when the variable consideration is related to satisfying that performance obligation and consistent with the allocation objective. The Company's revenue is generally recorded subsequent to receipt of payment authorization, utilizing credit cards, wire transfers and PayPal, an Internet based payment system, as methods of payments. Goods are generally not shipped before payment is received. For certain transactions, payment is due upon invoice and the payment terms vary depending on the business segment.

The Company collects and remits sales taxes on merchandise that it purchases and sells and has elected the practical expedient to report such amounts under the net method in its Consolidated Statements of Operations. The Company also provides shipping and handling services in some arrangements and has elected the practical expedient to treat those activities as a fulfillment cost. If the Company is acting as a principal for the combined obligation, amounts received from customers for shipping are recognized as revenue, and amounts paid for shipping are recognized as costs of goods sold. If the Company is acting as an agent for the combined obligation, shipping revenue and costs will be netted and recognized within costs of goods sold.

The Company’s performance obligations are satisfied when control of the asset is transferred to the Buyer or when the service is completed. The Company determines when control has transferred by evaluating the following five indicators: (1) whether the Company has a present right to payment for the asset or assets; (2) whether the Buyer has legal title to the asset; (3) whether the Buyer has physical possession of the asset or assets; (4) whether the Buyer has the significant risks and rewards of ownership; and (5) whether the Buyer has accepted the asset or assets.

For the Company's Machinio business segment, the performance obligation is satisfied over time as the Company provides the promotional placement services over the term of the subscription. At March 31, 2019, the Machinio business segment had a remaining performance obligation of $3.1 million that the Company expects the majority of this will be recognized as revenue over the next 12 months.

Cost of Goods Sold

Cost of goods sold includes the costs of purchasing and transporting property for auction, credit card transaction fees and shipping and handling costs. The Company purchases the majority of its inventory at a percentage of the vendor's last retail price under certain commercial contracts within its RSCG segment, and at specifically negotiated prices within its CAG segment. Title for the inventory passes to the Company at the time of purchase and the Company bears the risks and rewards of ownership. The Company does not have title to assets sold on behalf of its commercial or government sellers when it receives only sales commission revenue and, as such, recognizes no inventory or the corresponding cost of goods sold from inventory purchases associated with those sales.

Contract Assets

Contract assets reflect an estimate of expenses that will be reimbursed upon settlement with Seller. The contract asset balance was $0.7 million as of October 1, 2018 and $0.7 million as of March 31, 2019 and is included in the line item "Prepaid expenses and other current assets" on the consolidated balance sheet.

Contract Costs

Contract costs relate to sales commissions paid on consignment contracts that are capitalized. Contract costs are amortized over the expected life of the customer contract. The contract cost balance was approximately $0.1 million as of October 1, 2018 and $0.3 million as of March 31, 2019 and is included in the line item "Prepaid expenses and other current assets" and "Other assets" on the consolidated balance sheet. Amortization expense was immaterial during the three and six months ended March 31, 2019.

Promissory Note

On September 30, 2015, the Company sold certain assets related to its Jacobs Trading business to Tanager Acquisitions, LLC (the ‘‘Buyer’’). In connection with the disposition, the Buyer assumed certain liabilities related to the Jacobs Trading business. The Buyer issued a $12.3 million five-year interest bearing promissory note to the Company. Of the $12.3 million, $4.0 million has been repaid as of March 31, 2019. Of the remaining $8.3 million, $6.3 million is recorded on the consolidated balance sheet in Other assets, and $2.0 million in Prepaid expenses and other current assets as of March 31, 2019 based on the scheduled repayment dates.

Risk Associated with Certain Concentrations

The Company does not perform credit evaluations for the majority of its buyers. However, most sales are recorded subsequent to payment authorization being received. As a result, the Company is not subject to significant collection risk, as most goods are not shipped before payment is received.

For consignment sales transactions, funds are typically collected from buyers and are held by the Company on the sellers' behalf. The funds are included in Cash and cash equivalents in the Consolidated Balance Sheets. The Company releases the funds to the seller, less the Company's commission and other fees due, after the buyer has accepted the goods or within 30 days, depending on the state where the buyer and seller conduct business. The amount of cash held on behalf of sellers is recorded within Payables to sellers in the accompanying Consolidated Balance Sheets.

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash in banks over FDIC limits, certificates of deposit, and accounts receivable. The Company deposits its cash with financial institutions that the Company considers to be of high credit quality.

During the six months ended March 31, 2019, the Company had one material vendor contract with the Department of Defense (DoD) under which it acquired, managed and sold government property, the Scrap Contract. Revenue from the sale of property acquired under the Scrap Contract accounted for approximately 7.6% and 10.0% of the Company's consolidated revenue for the three months ended March 31, 2019 and 2018, respectively, and for approximately 7.6% and 9.2% of the Company's consolidated revenue for the six months ended March 31, 2019 and 2018, respectively. This contract is included within the Company's CAG segment. See Note 3, Significant Contracts, for information related to the Company's prior significant Surplus contact with the DoD, which was completed in fiscal 2018.

Additionally, the Company has a vendor contract with Amazon.com, Inc. under which the Company acquires and sells commercial merchandise. Transactions under this contract represented approximately 49.4% and 28.7% of cost of goods sold for the three months ended March 31, 2019 and 2018, respectively, and 44.9% and 24.1% of cost of goods sold for the six months ended March 31, 2019 and 2018, respectively. This contract is included within the Company's RSCG segment.

Earnings per Share

The Company calculates net income (loss) per share in accordance with Financial Accounting Standards Board ("FASB") Topic 260 Earnings Per Share (“ASC 260”). Under ASC 260, basic net income (loss) per common share is calculated by dividing net income (loss) by the weighted-average number of common shares outstanding during the reporting period. The weighted average number of shares of common stock outstanding includes vested restricted stock units. Diluted net income (loss) per share reflects the potential dilution that could occur assuming conversion or exercise of all dilutive unexercised stock options and unvested restricted stock units. The dilutive effect of unexercised stock options and unvested restricted stock units was determined using the treasury stock method. Under the treasury stock method, the proceeds received from the exercise of stock options, and the amount of compensation cost for future service not yet recognized by the Company are assumed to be used to repurchase shares of the Company’s common stock. Stock options and restricted stock units are not included in the computation of diluted net income (loss) per share when they are antidilutive.

For the three and six months ended March 31, 2019 and 2018, the basic and diluted weighted average common shares were the same because the inclusion of dilutive securities in the computation of diluted net income would have been anti-dilutive. See Note 7 for the amounts of outstanding stock options, restricted stock awards and restricted stock units that could potentially dilute net income (loss) per share in the future.

Recent Accounting Pronouncements

Accounting Standards Adopted

On October 1, 2018, the Company adopted ASC 606 using the modified retrospective transition method. The Company applied the new revenue standard to all contracts that were not completed as of October 1, 2018 on a modified retrospective basis and recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The comparative period information has not been restated and continues to be reported under the accounting standards in effect for those periods.

The cumulative effect of the changes made to the consolidated October 1, 2018 balance sheet for the adoption of ASC 606 was as follows (in thousands):



	Balance at September 30, 2018			Adjustment due to adoption of ASC 606		Balance as adjusted at October 1, 2018
Prepaid expenses and other current assets	$	7,816		$	671	$	8,487
Other assets	$	14,124		$	59	$	14,183
Retained earnings	$	(100,045	)	$	730	$	(99,315	)

The impact of adopting ASC 606 on the Company’s consolidated statement of operations and the consolidated balance sheet for the period ended March 31, 2019 was as follows (in thousands):



	Three months ended March 31, 2019									Six months ended March 31, 2019

In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting. ASU 2017-09 provides guidance about which changes to terms or conditions of share-based payment awards require the application of modification accounting in Topic 718, Compensation - Stock Compensation. The ASU was adopted on October 1, 2018 and the Company will apply the guidance in ASU 2017-09 on a prospective basis to its award modifications. No material impacts have been noted to date.

In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. ASU 2017-07 changes how employers that sponsor defined benefit pension and/or other postretirement benefit plans present the cost of the benefits in the income statement. Under this standard, employers will present the service cost component of net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. Employers will present the other components of the net periodic benefit cost separately from the line item(s) that includes the service cost and outside of any subtotal of operating income, if one is presented. The adoption of ASU 2017-07 on October 1, 2018, using the retrospective method, did not have a material impact on the Company's results of operations. As a result of adopting this standard $90 thousand and $182 thousand for three and six months ended March 31, 2018, respectively, were reclassified in the consolidated statement of operations from "General and administrative", a component of loss from operations, to "Interest and other income, net", which is included below loss from operations.

In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business. ASU 2017-01 clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. The ASU was adopted on October 1, 2018 and the Company will apply the guidance in ASU 2017-01 on a prospective basis when entering into acquisitions of assets or businesses. No material impacts have been noted to date.

In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory. The new standard requires companies to recognize the income tax effects of intercompany sales or transfers of assets, other than inventory, in the income statement as income tax expense (or benefit) in the period the sale or transfer occurs. The exception to recognizing the income tax effects of intercompany sales or transfers of assets remains in place for intercompany inventory sales and transfers. The adoption of ASU 2016-16 on October 1, 2018 did not have an impact on the Company’s consolidated statement of operations.

During 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments and ASU 2016-18, Restricted Cash. These ASUs clarify how entities should classify certain cash receipts and cash payments on the statement of cash flows and requires that the statement of cash flows explain the change during the period in the total cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. These standards were adopted on October 1, 2018 on a retrospective basis and there was no impact on the Company's consolidated statement of cash flows.

Accounting Standards Not Yet Adopted

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. ASU 2018-15 aligns the requirements for capitalizing implementation costs in a cloud computing arrangement with the requirement for capitalizing implementation costs incurred to develop or obtain internal-use software. This ASU will become effective for the Company beginning October 1, 2020. The Company is currently evaluating the effect that the ASU might have on its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 amends the existing accounting standard for defined benefit plans by removing, modifying, and adding certain disclosures. This ASU will become effective for the Company beginning October 1, 2021 with early adoption permitted. The Company is currently evaluating the timing of adoption the new guidance as well as the impact it may have on the consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurements. ASU 2018-13 amends the existing accounting standard for fair value measurement by removing, modifying, and adding certain disclosures. This ASU will become effective for the Company beginning October 1, 2020 with early adoption permitted. The Company is currently evaluating the timing of adopting the new guidance as well as the impact it may have on the consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-based Payment Accounting. ASU 2018-07 amends the existing accounting standards for share-based payments to nonemployees. ASU 2018-07 applies to all share based payment transactions in which a grantor acquires goods or services to be used or consumed in its own operation by issuing share-based payment awards. Additionally, this guidance clarifies that Topic 718 does not apply to share based payments used to effectively provide financing to the issuer or awards granted in conjunction with selling goods or services to customers as part of a contract accounted under ASC 606. ASU 2018-07 will become effective for the Company beginning October 1, 2019. The Company is currently evaluating the effect the adoption of the standard is expected to have on its consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018-02 allows entities to elect to classify from accumulated other comprehensive income (loss) to retained earnings stranded tax effects resulting from the Tax Cuts and Jobs Act (the "Tax Act") enacted on December 22, 2017. An entity that does not elect to reclassify the income tax effects of the Tax Act shall disclose in the period of adoption a statement that the election was not made. This guidance will become effective for the Company beginning on October 1, 2019. The Company is currently evaluating whether it will make an election to reclassify the income tax effects of the Tax Act from accumulated other comprehensive income to retained earnings.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment. Under ASU 2017-04 the entity is required to perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity is required to recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity is required to consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. This guidance will become effective for the Company beginning on October 1, 2020. The Company is currently evaluating the methods of adoption allowed by the new standard and the effect the adoption of the standard is expected to have on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), or ASC 842. ASC 842, including all the amendments and guidance, will change the way the Company recognizes its leased assets. It will require organizations that lease assets—referred to as "lessees"—to recognize on the balance sheet the assets and liabilities representing the rights and obligations created by those leases. ASC 842 will also require disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. The guidance will be effective for the Company beginning on October 1, 2019. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into, after either the adoption date or the beginning of the earliest comparative period presented in the financial statements. The Company is in the process of aggregating its worldwide lease portfolio and is evaluating the potential to use software solutions in its adoption of ASC 842 and for its subsequent lease accounting requirements. Once completed, the Company will elect a transition method for adoption and conclude on whether to make use of the available practical expedients. The adoption of ASC 842 will result in the recognition of right-of-use assets and lease liabilities on its Consolidated Balance Sheets, and will require that the Company make quantitative and qualitative disclosures about its leases. Additional impacts, which may be material, may be identified as the Company completes its adoption process.

Significant Contracts	6 Months Ended
Significant Contracts	Mar. 31, 2019
Contractors [Abstract]
Significant Contracts	Significant Contracts Historically, the Company had two material vendor contracts with the DoD, the Scrap Contract and the Surplus Contract. Under the Scrap Contract, the Company is the remarketer of all DoD non-electronic scrap turned into the Defense Logistics Agency (DLA) available for sale within the United States, Puerto Rico, and Guam. The current Scrap Contract was awarded to the Company in April 2016. The Scrap Contract has a 36-month base term that commenced in the first quarter of fiscal year 2017, with two 12-month extension options exercisable by the DLA. The base term of the Scrap Contract will expire on September 30, 2019. The Company pays a revenue-sharing payment to the DLA under this contract equal to 64.5% of the gross resale proceeds of the scrap property, and the Company bears all of the costs for the sorting, merchandising and sale of the property. The contract contains a provision permitting the DLA to terminate the contract for convenience upon written notice to the Company. Revenue from the Scrap Contract accounted for approximately 7.6% and 10.0% of the Company's consolidated revenue for the three months ended March 31, 2019 and 2018, respectively, and 7.6% and 9.2% of the Company's consolidated revenue for the six months ended March 31, 2019 and 2018, respectively. The Surplus Contract was a competitive-bid contract under which the Company acquired, managed and sold usable DoD surplus personal property turned into the DLA. Surplus property generally consisted of items determined by the DoD to be no longer needed, and not claimed for reuse by any federal agency, such as electronics, industrial equipment, office supplies, scientific and medical equipment, aircraft parts, clothing and textiles. The Surplus Contract required the Company to purchase all usable surplus property offered to the Company by the DoD at 4.35% of the DoD's original acquisition value. On October 11, 2017, the DLA published a Request for Technical Proposal (“RFTP”) and draft Invitation for Bid (IFB) for the sale of surplus, useable non-rolling stock property. The RFTP and IFB related to the DLA’s award of two new term surplus contracts. On December 5, 2017, the DLA determined that the Company was not the high bidder for either of the two contracts. The Company made its final inventory purchase under the Surplus Contract during December 2017, and as of June 30, 2018, had completed its wind-down of operations under the Surplus Contract. Revenue from the Surplus Contract accounted for approximately zero and 19.3% of the Company's consolidated revenue for the three months ended March 31, 2019 and 2018, respectively, and zero and 22.9% of the Company's consolidated revenue for the six months ended March 31, 2019 and 2018, respectively.

Income Taxes	6 Months Ended
Income Taxes	Mar. 31, 2019
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, the Tax Act was signed into law. The Tax Act reduces the corporate tax rate from 35% to 21%. During the three months ending December 31, 2017, the Company revised its estimated annual effective tax rate to reflect this change in the statutory rate. The rate change was administratively effective at the beginning of the Company's 2018 fiscal year, using a blended rate of 24.5%. At September 30, 2018, the Company had not yet completed its accounting for the tax effects of the Tax Act; however, the Company recorded a provisional benefit of $10.7 million in 2018 for the remeasurement of its deferred tax balance and recognition of the realizability of the deferred tax assets. During the three months ended December 31, 2018, the Company completed its accounting for the tax effects of the Tax Act and determined no change to the amount recorded in fiscal year 2018 was required. The international provisions of the Tax Act establish a territorial tax system and subject certain foreign earnings on which U.S. tax is currently deferred to a one-time transition tax. During the three months ended December 31, 2018, the Company completed its analysis of foreign earnings and profits and determined that no one-time transition tax was due. As a result, the Company has not recorded any amount in its financial statements for fiscal year 2018 or the six months ended March 31, 2019 for such transition tax. The Tax Act subjects a U.S. shareholder to a minimum tax on “global intangible low-taxed income” (“GILTI”) earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740 No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI resulting from those items in the year the tax is incurred. The Company has elected to recognize the resulting tax on GILTI as a period expense in the period the tax is incurred. The Company’s interim effective income tax rate is based on management’s best current estimate of the Company's expected annual effective income tax rate. The Company recorded a pre-tax loss in the first six months of fiscal year 2019 and its corresponding effective tax rate is approximately -6.8%. Tax expense in the current period is due to state and foreign taxes paid. The effective tax rate differed from the statutory federal rate of 21% primarily as a result of the valuation allowance charge on current year losses and the impact of foreign, state, and local income taxes and permanent tax adjustments. The Company applies the authoritative guidance related to uncertainty in income taxes. ASC Topic 740, Income Taxes, states that a benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, on the basis of technical merits. The Company records unrecognized tax benefits as a reduction to its deferred tax asset for its net operating loss carryforward. The Company identified no new uncertain tax positions during the six months ended March 31, 2019. The Company’s policy is to recognize interest and penalties in the period in which they occur in the income tax provision. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, various state and local jurisdictions and in foreign jurisdictions, primarily Canada and the United Kingdom. As of March 31, 2019, none of the Company's federal or state income tax returns are under examination. The statute of limitations for U.S. federal income tax returns for years prior to fiscal 2015 is now closed. However, certain tax attribute carryforwards that were generated prior to fiscal 2015 may be adjusted upon examination by tax authorities if they are utilized.

2006 Omnibus Long-Term Incentive Plan

Under the 2006 Omnibus Long-Term Incentive Plan, as amended (the 2006 Plan), 13,000,000 shares of common stock were available for issuance as of September 30, 2016. On February 23, 2017, at the Company's annual meeting of stockholders, the stockholders approved amendments to the 2006 Plan to increase the number of shares available for issuance under the 2006 Plan by 3,300,000, to a total of 16,300,000 shares. The 2006 Plan has a fungible share pool so that awards other than options or stock appreciation rights granted would be counted as 1.5 shares from the shares reserved for issuance.

The maximum number of shares subject to options or stock appreciation rights that can be awarded under the 2006 Plan to any person is 1,000,000 per year. The maximum number of shares that can be awarded under the 2006 Plan to any person, other than pursuant to an option or stock appreciation right, is 700,000 per year.

The following table presents the number of stock options and shares of restricted stock granted to employees under the Company's 2006 Plan and the grant date fair value of those stock awards for the periods presented:



	Three Months Ended March 31,				Six Months Ended March 31,

Weighted average grant date fair value	$	7.40	$	7.33	$	5.66	$	6.53

Stock options and restricted stock generally vest over four years. The fiscal year 2019 market-based options and restricted stock units will vest in installments based on the total shareholder return of the Company's common stock over a four-year performance period. The performance based restricted stock awards will vest in installments based on achievement of certain annual revenue and adjusted EBITDA targets through calendar year 2021, in each case, subject to each recipient's continued employment with the Company.

In determining the fair value for stock options, volatility rates over the last three years have ranged from 49.71% to 54.93%, the dividend rate has been 0% and the risk free interest rates have ranged from 1.65% to 2.78%.

Cash-Settled Stock Appreciation Rights

The Company issues cash-settled stock appreciation rights to non-executives with restrictions that lapse upon either the passage of time (service vesting), achievement of performance targets (performance vesting), achievement of market conditions (market vesting) or some combination of these conditions. The stock appreciation rights that include only service vesting conditions generally vest over a period of one to four years conditioned on continued employment for the incentive period. For performance vesting, stock appreciation rights generally vest and pay out on the achievement of financial metrics over a four year period conditioned on continued employment for the incentive period. Cash-settled stock appreciation rights are recorded as liability awards.

The Company did not issue any cash-settled stock appreciation rights during the three months ended March 31, 2019. During the six months ended March 31, 2019, the Company issued 95,000 cash-settled stock appreciation rights at an exercise price of $6.11. During the three months ended March 31, 2019, 51,614 cash-settled stock appreciation rights were exercised and 21,868 cash-settled stock appreciation rights were canceled. During the six months ended March 31, 2019, 101,170 cash-settled stock appreciation rights were exercised and 388,048 cash-settled stock appreciation rights were canceled. As of March 31, 2019, 539,987 cash-settled stock appreciation rights were outstanding.

During the comparable period in fiscal year 2018, the Company did not issue any cash-settled stock appreciation rights. During the three months ended March 31, 2018, 33,520 cash-settled stock appreciation rights were exercised and 177,947 cash-settled stock appreciation rights were canceled. During the six months ended March 31, 2018, 83,002 cash-settled stock appreciation rights were exercised and 272,904 cash-settled stock appreciation rights were canceled. As of March 31, 2018, 1,097,727 cash-settled stock appreciation rights were outstanding.

Share Repurchase Program

The Company is authorized to repurchase issued and outstanding shares of its common stock under a share repurchase program approved by the Company's Board of Directors. Share repurchases may be made through open market purchases, privately negotiated transactions or otherwise, at times and in such amounts as management deems appropriate. The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements and other market conditions. The repurchase program may be discontinued or suspended at any time and will be funded using available cash. The Company's Board of Directors reviews the share repurchase program from time to time, the last such review having occurred in May 2016. The Company did not repurchase shares under this program during the six months ended March 31, 2019 or 2018. As of March 31, 2019, the Company may repurchase an additional $10.1 million in shares under this program.

Fair Value Measurement

6 Months Ended

Mar. 31, 2019

Fair Value Disclosures [Abstract]

Fair Value Measurement

The Company measures and records in the accompanying consolidated financial statements certain assets and liabilities at fair value on a recurring basis. Authoritative guidance issued by the FASB establishes a fair value hierarchy for those instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s assumptions (unobservable inputs). The hierarchy consists of three levels:


Level 1	Quoted market prices in active markets for identical assets or liabilities;


Level 2	Inputs other than Level 1 inputs that are either directly or indirectly observable; and


Level 3	Unobservable inputs developed using estimates and assumptions developed by the Company, which reflect those that a market participant would use.

During the year ended September 30, 2018, as a result of the acquisition of Machinio, the Company recorded contingent consideration which is measured at fair value (Level 3) at March 31, 2019 and September 30, 2018. The Company estimated the fair value of the contingent consideration using a Monte Carlo simulation. The simulation estimated Machino's EBITDA over the earn out period using a market-based volatility factor and market interest rates resulting in an average EBITDA, which then a present value factor was applied based on the expected settlement date of the contingent consideration. The liability for this consideration is included in Deferred taxes and other long-term liabilities in the Consolidated Balance Sheets. During the six months ended March 31, 2018, the Company had financial assets measured at fair value (Level 3) that represented the value of rights the Company held from its participation in certain principal transactions in the Company's commercial business. The Company no longer held these assets at September 30, 2018.

The Company has investments of $30 million and $20 million at March 31, 2019 and September 30, 2018, respectively, in certificates of deposit with maturities of six months or less, and interest rates between 2.2% and 2.8%. These assets were measured at fair value at March 31, 2019 and September 30, 2018 and were classified as Level 1 assets within the fair value hierarchy.

The changes in the earn-out liability and financial assets measured at fair value using Level 3 inputs to determine fair value for the six months ended March 31, 2019 and 2018, respectively, are as follows (in thousands):



	Contingent Consideration

Balance at September 30, 2018	$	1,300
Settlements	—
Change in fair value	1,400
Balance at March 31, 2019	$	2,700

The increase in the fair value is primarily due to an increase in Machinio's estimated EBITDA over the earn out period, which was the result of realized EBITDA for the three months ended March 31, 2019 exceeding the previous estimate. Secondary factors for the increase in fair value relate to the present value factor, which was impacted by a shorter period until the earn out payment date, as well as a change in market conditions that reduced interest rates and the weighted average cost of capital.



	Financial Instruments

Balance at September 30, 2017	$	491
Settlements	(401		)
Change in fair value	(90		)
Balance at March 31, 2018	$	—

When valuing its Level 3 liability, management’s estimation of fair value is based on the best information available in the circumstances and may incorporate management's own assumptions around market demand which could involve a level of judgment, taking into consideration a combination of internal and external factors. Changes in the fair value of the Company's Level 3 asset and liability are recorded in Other operating expenses in the Consolidated Statements of Operations.

The Company’s financial assets and liabilities not measured at fair value are cash and cash equivalents (which includes cash and commercial paper with original maturities of less than 90 days), accounts receivable, a promissory note and accounts payable. The Company believes the carrying values of these instruments approximate fair value.

At March 31, 2019 and September 30, 2018, the Company did not have any assets or liabilities measured at fair value on a non-recurring basis.

Guarantees [Abstract]
Guarantees	Guarantees During the second quarter of 2015, the Company issued a guarantee to GoIndustry (the "Subsidiary") and the Trustees (the “Trustees”) of the HB Pension Fund. Under the arrangement, the Company irrevocably and unconditionally (a) guarantees to the Trustees punctual performance by the Subsidiary of all its Guaranteed Obligations, defined as all present and future obligations and liabilities (whether actual or contingent and whether owed jointly or severally in any capacity whatsoever) of the Company to make payments to the HB Pension Fund up to a maximum of 10 million British pounds, (b) undertakes with the Trustees that, whenever the Subsidiary does not pay any amount when due in respect of its Guaranteed Obligations, it must immediately on demand by the Trustees pay that amount as if it were the principal obligor; and (c) indemnifies the Trustees as an independent and primary obligation immediately on demand against any cost, charge, expense, loss or liability suffered or incurred by the Trustees if any payment obligation guaranteed by it is or becomes unenforceable, invalid or illegal; the amount of the cost, charge, expense, loss or liability under this indemnity will be equal to the amount the Trustees would otherwise have been entitled to recover on the basis of a guarantee. The guarantee is a continuing guarantee that will extend to the ultimate balance of all sums payable by the Company in respect of its Guaranteed Obligations. As of March 31, 2019 and September 30, 2018, the Company's plan was in an overfunded status as the plan's assets exceeded the plan liabilities. The funded status of the HB Pension Fund as of September 30, 2018, was disclosed in Note 13, Defined Benefit Pension Plan, to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2018.

Restructuring and Related Activities [Abstract]

Business Realignment Expenses

During the fourth quarter of fiscal year 2017 the Company began to restructure its CAG business, resulting in severance costs incurred and the closure of several offices and legal entities in Europe and Asia for total restructuring costs of approximately $1.0 million. The Company continued to implement its CAG cost cutting initiatives during the year ended September 30, 2018. As discussed in Note 3, Significant Contracts, the Company was not the high bidder for the new surplus contracts, and completed winding down its operations under the Surplus Contract during the year ended September 30, 2018. As a result, the Company recognized an additional $1.7 million of restructuring costs in fiscal 2018. During the six months ended March 31, 2018 the Company recorded $1.3 million in restructuring costs, $0.8 million of which related to severance and occupancy costs for the Surplus Contract. The remaining restructuring balance at March 31, 2019 of $0.3 million in occupancy related charges is expected to be paid by fiscal 2020.

During fiscal year 2017, the Company reorganized its IronDirect business. As a result, the Company recorded approximately $1.1 million of restructuring charges in the aggregate through the year ended September 30, 2018 related to this restructuring. The Company continued its reorganization of the IronDirect business during the six months ended March 31, 2019 and decided to exit the business, resulting in severance costs recorded of approximately $0.2 million. The Company fully exited the IronDirect business and wound down its operations during January 2019. The balance was paid out as of March 31, 2019.

In June 2017, the Company entered into an agreement to sub-lease office space at 6931 Arlington Road, Bethesda, Maryland. On the sub-lease commencement date, the Company relocated its headquarters from 1920 L Street NW, Washington DC, to its current Bethesda location and recognized a $2.0 million cease-use charge in its consolidated statements of operations at September 30, 2017. At September 30, 2018, the remaining cease-use accrual was approximately $0.8 million. During the six months ended March 31, 2019, the Company paid down the cease-use charge by approximately $0.6 million. The remaining balance of approximately $0.2 million is expected to be paid during fiscal 2019. This activity is presented under occupancy cost in the table below.

During the six months ended March 31, 2018, the Company recognized $0.5 million in severance cost primarily related to the restructuring of its Corporate Information Technology department. This cost is recorded within the Corporate & Other line item below.

Segment Reporting [Abstract]

Segment Information

The Company provides results in four reportable operating segments: GovDeals, Capital Assets Group (CAG), Retail Supply Chain Group (RSCG) and Machinio. The GovDeals, CAG, RSCG and Machinio segments constitute approximately 99.6% of the Company's revenue during the six months ended March 31, 2019. Each reportable segment offers separately branded marketplaces to enable sellers to achieve their respective channel marketing objectives to reach buyers. Across its segments, the Company offers its sellers two primary transaction models, as well as a suite of services, and its revenues vary depending upon the models employed and the level of service required. A description of the reportable segments is provided below:

•

The GovDeals reportable segment provides self-directed service offerings in which sellers list their own assets, and it consists of marketplaces that enable local and state government entities, including city, county and state agencies, as well as commercial businesses located in the United States and Canada, to sell surplus and salvage assets. GovDeals also offers a suite of marketing services to sellers. This segment includes the Company's GovDeals.com and AuctionDeals.com marketplaces.

•

The CAG reportable segment provides fully-managed offerings to sellers and consists of marketplaces that enable federal government agencies, as well as commercial businesses, to sell surplus, salvage, and scrap assets. Sales of assets procured through our Surplus Contract, which wound down during 2018, and our Scrap Contract, are conducted through the Government Liquidation marketplace included in this segment. CAG also offers a suite of services that includes marketing services, surplus management and asset valuation. Commercial sellers are located in the United States, Europe, Australia and Asia. This segment includes the Company's Network International, GoIndustry DoveBid, and Government Liquidation marketplaces.

•

The RSCG reportable segment consists of marketplaces that enable corporations located in the United States and Canada to sell surplus and salvage consumer goods and retail capital assets. RSCG also offers a suite of services that includes returns management, asset recovery, and ecommerce services. This segment includes the Company's Liquidation.com, Liquidation.com DIRECT, and Secondipity marketplaces.


•	The Machinio reportable segment operates a global online platform for listing used equipment for sale in the construction, machine tool, transportation, printing and agriculture sectors. Machinio was acquired by the Company in July 2018.

Corporate & Other primarily consists of the Company's IronDirect operating segment that was not individually significant as a reportable operating segment as well as elimination adjustments. During January 2019, the Company exited out of the IronDirect business and fully wound down its operations. Iron Direct offered buyers access to construction equipment, parts and services through a single ecommerce marketplace.

Decisions concerning the allocation of the Company’s resources are made by the Company’s Chief Operating Decision Maker ("CODM"), which is the Company's Chief Executive Officer, with oversight by the Board of Directors. The Company reports segment information based on the internal performance measures used by the CODM to assess the performance of each operating segment in a given period. In connection with that assessment, the CODM uses segment gross profit to evaluate the performance of each segment. Segment gross profit is calculated as total revenue less cost of goods sold (exclusive of depreciation and amortization) and seller distributions.

The amount of our revenue that came from sales outside of the United States for the three months ended March 31, 2019 and 2018 was 14.6% and 11.1%, respectively, and 15.4% and 12.2% for the six months ended March 31, 2019 and 2018, respectively.
