Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Liquidity Services (the “Company”) operates a network of ecommerce marketplaces that enable buyers and sellers to transact in an efficient, automated environment offering over 500 product categories. 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's services include program management, valuation, asset management, reconciliation, returns process management ("RPM"), refurbishment and recycling, fulfillment, marketing and sales, warehousing and transportation, buyer support, compliance and risk mitigation, as well as self-service tools for its sellers. 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.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 used machinery and equipment at www.machinio.com. The Company has over 11,000 sellers, including Fortune 1000 and Global 500 organizations as well as federal, state, and local government agencies. The Company has five reportable segments, Retail Supply Chain Group (RSCG), Capital Assets Group (CAG), GovDeals, Machinio, and Corporate & Other. See Note 17 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. See Note 4 for further information on this acquisition. 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 not renew their contracts with the Company. The Company has evaluated subsequent events through the date that these financial statements were issued and filed with the Securities and Exchange Commission.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Principles of Consolidation and Basis of Presentation

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Certain prior period amounts have been reclassified to conform to the current year's presentation. All intercompany balances and transactions have been eliminated in consolidation.

The accompanying consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. In addition, in the opinion of management, all adjustments (consisting of normal, recurring accruals) considered necessary for a fair presentation of the results for the periods presented have been included.

Business Combinations

The Company recognizes all of the assets acquired, liabilities assumed, contractual contingencies, and contingent consideration at their fair value on the acquisition date. Acquisition-related costs are recognized separately from the acquisition and expensed as incurred. Restructuring costs incurred in periods subsequent to the acquisition date are expensed when incurred. Subsequent changes to the purchase price (i.e., working capital adjustments) or other fair value adjustments determined during the measurement period are recorded as an adjustment to goodwill, with the exception of contingent consideration, which is recognized in the statement of operations in the period it is modified. All subsequent changes to a valuation allowance or uncertain tax position that relate to the acquired company and existed at the acquisition date that occur both within the measurement period and as a result of facts and circumstances that existed at the acquisition date are recognized as an adjustment to goodwill. All other changes in valuation allowances are recognized as a reduction or increase to income tax expense or as a direct adjustment to additional paid-in capital as required.

Cash and Cash Equivalents

The Company considers all highly liquid securities purchased with an initial maturity of three months or less to be cash equivalents.

Short-term Investments

The Company's short-term investments at September 30, 2018 consisted of various certificates of deposit with maturities of six months or less, and interest rates between 2% and 2.5%.

Accounts Receivable

Accounts receivable are recorded at the invoiced amount and are non-interest bearing. The Company maintains an allowance for doubtful accounts to reserve for potentially uncollectible receivables. Allowances are based on management’s judgment, which considers historical experience and specific knowledge of accounts where collectability may not be probable. The Company makes provisions based on historical bad debt experience, a specific review of all significant outstanding invoices and an assessment of general economic conditions.

Inventory

Inventory consists of property obtained for resale, generally through the online auction process, and is stated at the lower of cost or net realizable value. Cost is generally determined using the specific identification method. Costs associated with our warehouse operations are expensed as incurred and included within technology and operations expenses in the Statements of Operations. Charges for unsellable inventory, as well as for inventory written down to expected market price, are included in Cost of goods sold in the period in which they have been determined to occur. During 2017, the Company recorded a $3.1 million inventory write-down within its IronDirect operating segment, as the carrying value of this inventory was written down to its expected market value. As of September 30, 2018, and 2017, the Company's inventory reflects write-downs of approximately $0.5 million and $4.6 million, respectively.

Prepaid expenses and other current assets

Prepaid expenses and other current assets includes prepaid income tax, financial assets, the short-term portion of a promissory note (described in "Other Assets"), as well as other miscellaneous prepaid expenses. Financial assets are related to participation agreements for principal transactions in the Company's commercial business. Changes in the fair value of the Company's financial assets are recorded in Other operating expense. See Note 12 for further information.

Other Assets

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 5-year interest bearing promissory note to the Company. Of the $12.3 million, $4.0 million has been repaid as of September 30, 2018. Of the $8.3 million outstanding at September 30, 2018, $6.3 million was recorded in Other assets, and $2.0 million in Prepaid expenses and other current assets as of September 30, 2018.

Property and Equipment

Property and equipment are recorded at cost, and depreciated or amortized on a straight-line basis over the following estimated useful lives:



Computers and purchased software		One to five years
Office equipment		Three to five years
Furniture and fixtures		Five to seven years
Internally developed software for internal-use		Seven years
Leasehold improvements		Shorter of lease term or useful life
Buildings		Thirty-nine years
Land		Not depreciated

Intangible Assets

Intangible assets primarily consist of contract intangibles, brand and technology, and patent and trademarks. Intangible assets are amortized using the straight-line method over their estimated useful lives, ranging from three to ten years.

Impairment of Long-Lived Assets

Long-lived assets, including definite lived intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. If an impairment indicator is present, the Company evaluates recoverability by comparing the carrying amount of the assets to future undiscounted net cash flows expected to be generated by the assets. If the assets are impaired, the impairment recognized is measured by the amount by which the carrying amount exceeds the estimated fair value of the assets. No impairment was recorded during the year ended September 30, 2018. During the year ended September 30, 2017, the Company recorded a $1.2 million impairment of a contract intangible associated with its IronDirect business, and a $0.6 million impairment to leasehold improvements, also associated with its IronDirect business.

Goodwill

The Company reviews goodwill for impairment annually or more frequently if events or circumstances indicate impairment may exist. Examples of such events or circumstances could include a significant change in business climate or the loss of a significant buyer. In evaluating goodwill for impairment, the Company first assesses qualitative factors to determine whether it is more than likely than not (that is, a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying amount. If the Company concludes that it is not more likely than not that the fair value of the reporting unit is less than its carrying value, no further testing of goodwill assigned to the reporting unit is required. However, if the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company applies a two-step fair value-based test to assess goodwill for impairment. The first step compares the fair value of a reporting unit to its carrying amount, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, the second step is then performed. The second step compares the carrying amount of the reporting unit's goodwill to the implied fair value of the goodwill. If the implied fair value of the goodwill is less than the carrying amount, an impairment loss would be recorded in the statement of operations.

The annual goodwill impairment assessment was performed as of July 1, 2018, for the year ended September 30, 2018.

Deferred Revenue

Deferred revenue is primarily derived from subscription fees charged to customers for promotional placement on Machinio's search engine over periods ranging from one to fifteen months. Subscription fees are recognized ratably over the term of the agreements.

Revenue Recognition

The Company recognizes revenue when all of the following criteria are met:


•	a buyer submits the winning bid in an auction and, as a result, evidence of an arrangement exists, and the sale price has been determined;


•	the buyer has assumed the risks and rewards of ownership; and


•	collection is reasonably assured.

The Company evaluates revenue 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 net commissions and related fees as revenue (when the Company acts as an agent). In arrangements in which the Company is deemed to be the primary obligor, bears physical and general inventory risk, and credit risk, the Company recognizes as revenue the gross proceeds from the sale, including buyer's premiums. The Company has evaluated its revenue recognition policy related to sales under its purchase transaction model and determined it is appropriate to account for these sales on a gross basis. In the Company's evaluation, the Company relied most heavily upon its status as primary obligor in the sales relationship and the fact that the Company has general inventory risk.

In arrangements in which the Company acts as an agent or broker on a consignment basis, without taking physical or general inventory risk, the Company recognizes 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. Such revenue as well as other fee revenue is presented as Fee Revenue in the Consolidated Statements of Operations.

The Company collects and remits sales taxes on merchandise that it purchases and sells and reports such amounts under the net method in its Consolidated Statements of Operations.

The Company records revenue for subscriptions to Machinio's search engine on a straight-line basis over the term of the agreement.

Cost of Goods Sold

Cost of goods sold includes the costs of purchasing and transporting property for auction as well as credit card transaction fees. The Company purchases the majority of its inventory at a percentage of the vendor's original acquisition cost under the Surplus Contract and certain commercial contracts, and at a percentage of the vendor's last retail price under certain commercial contracts. 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 and related cost of goods sold associated with those sales. Cost of goods sold also includes shipping and handling costs.

Risk Associated with Certain Concentrations

For the majority of buyers that receive goods before payment to the Company is made, credit evaluations are performed. However, for the remaining buyers, goods are not shipped before payment is made, and as a result the Company is not subject to significant collection risk from those buyers.

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 financial statements. 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 the sellers is recorded as 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 and cash equivalents in banks over FDIC limits, and accounts receivable. The Company deposits its cash with financial institutions that the Company considers to be of high credit quality.

During the years ended September 30, 2018, 2017, and 2016, the Company had two material vendor contracts with the Department of Defense (DoD) under which it acquired, managed and sold government property. Revenue from the sale of property acquired, as well as provision of services, under the Surplus Contract accounted for 12.4%, 27.6%, and 31.0%, of the Company's consolidated revenue for the years ended September 30, 2018, 2017, and 2016, respectively. Revenue from the sale of property acquired under the Scrap Contract accounted for approximately 10.2%, 11.1% and 10.2% of the Company's total revenue for the years ended September 30, 2018, 2017, and 2016, respectively. These contracts are included within the Company's CAG segment. See Note 3, Significant Contracts, for further information related to the wind-down of the Surplus Contract.

Additionally, the Company has multiple vendor contracts with Amazon.com, Inc. under which it acquires and sells commercial merchandise. The property purchased under this contract represented approximately 33.7%, 21.8%, and 12.1% of cost of goods sold for the years ended September 30, 2018, 2017, and 2016, respectively. This contract is included within the RSCG segment.

Income Taxes

The Company accounts for income taxes using an asset and liability approach for measuring deferred taxes based on temporary differences between the financial statement and income tax bases of assets and liabilities existing at each balance sheet date using enacted tax rates for the years in which the taxes are expected to be paid or recovered. The Company recognizes deferred tax assets to the extent that it believes that these assets are more likely than not to be realized. In making such determination, the Company considers all available positive and negative evidence to estimate whether future taxable income will be generated to permit use of the existing deferred tax asset. The resulting net tax asset reflects management's estimate of the amount that will be realized.

The Company applies the authoritative guidance related to uncertainty in income taxes. Accounting Standards Codification (ASC) 740 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 resolutions 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. During the year ended September 30, 2018, the Company did not record any unrecognized tax benefits. 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 including, among others, Canada and the U.K.

Stock-Based Compensation

The Company estimates the fair value of share-based awards on the date of grant. The Company issues stock options and stock appreciation rights with restrictions that lapse upon either the passage of time (service vesting conditions), the achievement of performance targets (performance vesting conditions), or some combination thereof. In addition, the Company issues stock options that vest upon the achievement of certain Company stock price targets (market vesting conditions). The fair value of stock options and stock appreciation rights with service and/or performance vesting conditions is determined using the Black-Scholes option-pricing model. For those stock options with only service vesting conditions, the Company recognizes compensation cost on a straight-line basis over the explicit service period. For stock options with both performance and service vesting conditions, the Company starts recognizing compensation cost over the remaining service period, when it is probable the performance condition will be met. The stock appreciation rights that include only service conditions generally vest over a period of one to four years conditioned on continued employment for the incentive period.

The Company issues restricted stock units with service vesting conditions, performance vesting conditions, and market vesting conditions, or some combination thereof. For those restricted stock units with only service vesting conditions, the Company recognizes compensation cost on a straight-line basis over the explicit service period. The Company also issues restricted stock awards with service and performance vesting conditions. For restricted stock awards and units with both performance and service vesting conditions, the Company starts recognizing compensation cost over the remaining service period when it is probable the performance condition will be met. The fair value of restricted stock awards and units with service vesting and/or performance vesting conditions is based on the closing price of the Company’s common stock on the date of grant.

For the Company's stock options and restricted stock units with market vesting conditions, the ultimate number of shares to be earned depends on the Company's total shareholder return during the performance period. The fair value of these stock options and restricted stock units is estimated on the grant date using a Monte Carlo simulation model. The Company recognizes compensation cost for stock options and restricted stock units with market vesting conditions over the derived service period.

The determination of the fair value of the Company’s stock options and stock appreciation rights with service and performance vesting conditions is based on a variety of factors including, but not limited to, the Company’s common stock price on the date of grant, expected stock price volatility over the expected life of units, expected term, risk-free rate, and dividend yield. The determination of the fair value of the Company’s stock options and restricted stock units with service and market vesting conditions is based on a variety of factors including, but not limited to, the Company’s common stock price on the grant date, expected stock price volatility, risk free interest rate, dividend yield, and projected exercise behavior.

Upon adoption of ASU 2016-09, Compensation - Stock Compensation (Topic 718), in the first quarter of 2018, the Company recognized forfeitures of share-based awards as they occur in the period of forfeiture rather than estimating the number of awards expected to be forfeited at the grant date and subsequently adjusting the estimate when awards are actually forfeited. The change in accounting policy resulted in an adjustment to retained earnings of $0.2 million as of October 1, 2017.

Stock options and restricted stock units that contain performance vesting or market vesting conditions are excluded from, diluted earnings per share computations until the applicable contingency is met as of the end of that reporting period.

The Company presents the cash flows from the tax benefits resulting from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) as an operating activity in the Consolidated Statements of Cash Flows.

Advertising Costs

Advertising expenditures are expensed as incurred. Advertising costs charged to expense were $3.6 million, $5.2 million and $6.0 million for the years ended September 30, 2018, 2017 and 2016, respectively.

Fair Value of Financial Instruments

Cash and cash equivalents, accounts receivable, accounts payable, profit-sharing distributions payable, and payables to sellers reported in the Consolidated Balance Sheets approximate their fair values. During the year ended September 30, 2018, the Company held financial assets that were related to participation agreements for principal transactions in the Company's commercial business. At September 30, 2018, the Company no longer held such financial assets.

Lastly, at September 30, 2018 the Company held short-term investments which consisted of various certificates of deposit with maturities of six months or less, and interest rates between 2% and 2.5%.

In addition, as a result of the Machinio acquisition, the sellers are eligible to receive earn-out consideration up to $5.0 million. The earn-out consideration was valued at approximately $1.2 million at the acquisition date.

Changes in the fair value of the Company's financial instruments are recorded in Other operating expense.

Foreign Currency Translation

The functional currency of the Company's foreign subsidiaries is primarily the local currency. The translation of the subsidiary's financial statements into U.S. dollars is performed for balance sheet accounts using exchange rates in effect at the balance sheet date and for revenue and expense accounts using an average exchange rate during the period. The resulting translation adjustments are recognized in accumulated other comprehensive (loss) income, a separate component of stockholders' equity. Realized foreign currency transaction gains and losses for 2018, 2017 and 2016 are included in interest and other income (expense), net in the Consolidated Statements of Operations.

Accumulated Other Comprehensive Income (loss)

The following table shows the changes in accumulated other comprehensive income (loss), net of taxes (in thousands):



	Foreign Currency Translation Adjustments			Net Change Pension and Other Postretirement Benefit Plans			Accumulated Deficit
Balance at September 30, 2015	$	(6,947	)	$	1,321		$	(5,626	)
Current-period other comprehensive (loss) income	(398		)	(2,547		)	(2,945		)
Balance at September 30, 2016	(7,345		)	(1,226		)	(8,571		)

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 (“EPS”) 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, the amount of compensation cost for future service not yet recognized by the Company and the amount of tax benefits that would be recorded in additional paid-in capital when stock options become deductible for income tax purposes are all 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.

The Company has not included the following stock options in the calculation of diluted income per share because the option exercise prices were greater than the average market prices for the applicable periods:

(a) for the year ended September 30, 2018 1,170,125 options;

(b) for the year ended September 30, 2017 1,023,072 options; and

For the years ended September 30, 2018, 2017 and 2016, the basic and diluted weighted average common shares were the same because the inclusion of dilutive securities would have been anti-dilutive. Diluted net income attributable to common stockholders per share includes the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. See Note 11 for outstanding stock options and unvested restricted stock, all of which are anti-dilutive as of September 30, 2018.

Recent Accounting Pronouncements

Accounting Standards Adopted

In March 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-09, Compensation - Stock Compensation (Topic 718). This update was issued as part of the FASB’s simplification initiative and affects all entities that issue share-based awards to their employees. The amendments in this update cover such areas as the recognition of excess tax benefits and deficiencies and an accounting policy election for forfeitures. As part of the new guidance:

•Excess tax benefits and deficiencies arising from share-based awards are reflected in the condensed consolidated statements of operations as income tax expense rather than within stockholders’ equity.

•Excess tax benefits will be presented as an operating activity on the statement of cash flows rather than as a financing activity.

•A forfeiture election will be made to either estimate forfeitures (similar to the requirement in effect prior to adoption of the update) or recognize actual forfeitures as they occur. Entities will apply the forfeiture election provision using a modified retrospective transition approach, with a cumulative effect adjustment recorded to retained earnings as of the beginning of the period of adoption.

•Methods used to satisfy statutory tax withholding requirements by employers who withhold shares upon settlement of an award on behalf of an employee to cover tax obligations are broadened to allow for a range of withholding from the minimum to the maximum statutory allowable amounts.

The Company adopted the provisions of this guidance during the first quarter of 2018 as follows:

•Excess tax benefits and deficiencies arising from share-based awards are reflected within the Consolidated Statements of Operations as income tax expense; adopted prospectively, with no impact to prior year amounts;

•Excess tax benefits are presented as an operating activity on the statement of cash flows; adopted prospectively with no impact on prior year amounts.

As part of its adoption of ASU 2016-09, the Company made an accounting policy election to change the way in which it accounts for forfeitures of share-based awards. Specifically, beginning in the first quarter of 2018, the Company recognizes forfeitures of share-based awards as they occur in the period of forfeiture rather than estimating the number of awards expected to be forfeited at the grant date and subsequently adjusting the estimate when awards are actually forfeited. The change in accounting policy resulted in an adjustment to retained earnings as of October 1, 2017 of approximately $0.2 million.

Accounting Standards Not Yet Adopted

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805). 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. This guidance will become effective for the Company beginning on October 1, 2018. The amendments in this update should be applied prospectively on or after the effective date. No disclosures are required at transition. The Company does not expect the adoption of this standard to have a material effect upon the consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which supersedes most existing revenue recognition guidance under GAAP. The new standard will change the way the Company recognizes revenue and significantly expand the disclosure requirements for revenue arrangements. The guidance may be adopted either retrospectively or on a modified retrospective basis whereby the new standard would be applied to new and existing arrangements with remaining performance obligations as of the effective date, with a cumulative catch-up adjustment recorded to retained earnings at the effective date for existing arrangements with remaining performance obligations. During the year ended September 30, 2017, the Company initiated a formal project to assess the new standard, which was completed in three phases: an assessment phase, a design phase, and an implementation phase. The Company completed the assessment phase, which consisted of reviewing a representative sample of contracts, engaging in discussions with key stakeholders, and cataloging potential impacts on the Company’s accounting policies, financial statements, and systems and processes. The Company has also completed the design phase, which consisted of performing an in-depth contract review process, drafting a set of accounting policies in compliance with the new standard, and quantifying the impact of the adoption of this new standard. The Company is currently in the process of implementing the new standard during the first quarter of 2019. The Company has decided to adopt the standard on a modified retrospective basis. The expected impact on the Company's reported results of adopting the new standard is a $0.8 million increase to retained earnings, with the offset as an increase to the Company's assets at the transition date of October 1, 2018. An estimated $0.7 million of this impact results from the recognition of variable consideration at the point in time in which it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty is resolved. The remaining impact of $0.1 million relates to the recognition of sales commissions paid to certain employees for costs to obtain contracts that will benefit the Company over an estimated period of greater than twelve months.

In February 2016, the FASB issued ASU 2016-2, Leases. ASU 2016-02 will change the way the Company recognizes its leased assets. ASU 2016-2 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. ASU 2016-2 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, the beginning of the earliest comparative period presented in the financial statements. The Company is currently evaluating the new standard and the effect that adoption of the standard is expected to have on the Company's consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350). 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.

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. This guidance will become effective for the Company beginning on October 1, 2018. The Company is currently evaluating its adoption of this standard. The Company does not expect the adoption of this standard to have a significant impact on the Company’s consolidated financial statements and related disclosures.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): 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 enacted on December 22, 2017. An entity that does not elect to reclassify the income tax effects of the Tax Cuts and Jobs 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 the methods of adoption of the new standard and the effect that adoption of the standard is expected to have on the Company’s consolidated financial statements and related disclosures.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The update provides new guidance regarding the classification of debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investments, beneficial interests in securitized transactions, and separately identifiable cash flows and application of the predominance principle. This guidance will become effective for the Company beginning on October 1, 2018. Early adoption of the standard is permitted. The Company does not expect the adoption of this standard to have a significant impact on the Company’s consolidated financial statements and related disclosures.

Significant Contracts	12 Months Ended
Significant Contracts	Sep. 30, 2018
Contractors [Abstract]
Significant Contracts	Significant Contracts DLA Disposition Services 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 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 10.2%, 11.1%, and 10.2% of the Company's consolidated revenue for the years ended September 30, 2018, 2017 and 2016, 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 the DoD determined were 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. The Company retained 100% of the profits from the resale of the property and bore all of the costs for the merchandising and sale of the property. Included in Accrued expenses and other current liabilities in the Consolidated Balance Sheet is a liability to the DoD for the inventory that has not been paid for in the amount of zero, $6.2 million and $16.1 million, as of September 30, 2018, 2017 and 2016, respectively, 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 the Surplus Contract. Revenue from the Surplus Contract accounted for approximately 12.4%, 27.6% and 31.0%, of the Company's consolidated revenue for the years ended September 30, 2018, 2017 and 2016, respectively.

Business Combinations [Abstract]

Acquisition

Machinio

On July 10, 2018, the Company, entered into a definitive agreement to acquire 100% of the issued and outstanding capital stock of Machinio, a Delaware corporation. Machinio operates a global online platform for listing used equipment for sale in the construction, machine tool, transportation, printing and agriculture sectors. The primary reason for the acquisition was to expand the services and channels the Company offers to its sellers, and to grow the Company's network of buyers. For segment reporting purposes, Machinio is a separate reportable segment.

The consideration paid to the Sellers for the acquisition of Machinio equity was approximately $19.9 million in cash, earn-out consideration, and Company equity, including the acquisition of Machinio cash of approximately $1.5 million at the closing and a closing working capital purchase price adjustment (for a net cash consideration of approximately $16.7 million). Shares of restricted stock of the Company issued in a private placement to Machinio executives in exchange for their shares of Machinio stock valued at approximately $2.0 million were included in the consideration. In addition, the Machinio sellers are eligible to receive earn-out consideration up to $5.0 million. The earn-out consideration was valued at approximately $1.2 million at the acquisition date.

In connection with the acquisition, the Company issued restricted stock units and restricted stock awards valued at approximately $4.7 million in the aggregate to Machinio’s executives and employees. The restricted stock units and restricted stock awards are subject to performance-based vesting, based upon the 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 on such vesting dates and other standard terms and conditions set forth in the respective grant agreements.

Under the acquisition method of accounting, the total estimated purchase price is allocated to Machinio's net tangible and intangible assets acquired based on their estimated fair values as of July 10, 2018. Based on management's valuation of the fair value of tangible and intangible assets acquired and liabilities assumed, goodwill of approximately $14.6 million was recorded, of which zero is deductible for tax purposes. The purchase price was allocated as follows:



	Consideration Amount
	(in thousands)
Other Current Assets	$	106
Goodwill	14,558
Customer relationships intangible asset	3,100
Developed technology intangible asset	2,700
Trade name intangible asset	1,500
Property and equipment and other long-term assets	252
Liabilities excluding deferred revenue	(956		)
Deferred revenue	(1,400		)
Total consideration	$	19,860

Related to the recognition of intangible assets for customer relationships, developed technology, and trade name, as well as the earn-out consideration and deferred revenue, certain nonrecurring fair value measurements were performed as of the acquisition date under the provisions of ASC 805. The fair value measurements were classified as Level 3 assets within the fair value hierarchy under the provisions of ASC 820 and ASC 805. The significant unobservable inputs used in the fair value measurements categorized within Level 3 of the fair value hierarchy were rates of return ranging from 30% to 35% for the identifiable intangible assets and deferred revenue and 12% to 17% for the contingent consideration. The valuation processes used included the relief from royalty method and the multi-period excess earnings method for the identifiable intangible assets, cost to fulfill method for the deferred revenue, and a lattice valuation method to estimate the fair value of the contingent consideration.

The net sales and operating losses of Machinio included within the Consolidated Financial Statements since the date of acquisition was $0.7 million and $(0.9) million for the year ended September 30, 2018.

The following pro-forma financial information presents the Company's results as if the acquisition had occurred on October 1, 2016:

During the year ended September 30, 2018, the Company transferred $0.4 million from Construction in progress to internally developed software for internal-use and capitalized an additional $2.5 million in cost associated with internally developed software for internal-use. During the year ended September 30, 2017, the Company transferred $3.9 million from Construction in progress to internally developed software for internal-use and capitalized an additional $3.2 million in cost associated with internally developed software for internal-use.

Amortization of internally developed software for internal-use was $1.4 million and $0.4 million for the years ended September 30, 2018 and September 30, 2017. There was no amortization expense for internally developed software for internal-use in 2016.

The Company did not record fixed asset impairment charges in 2018. During the year ended September 30, 2017, the Company recorded $0.6 million in fixed asset impairment charges associated with leasehold improvements in its IronDirect business. These impairment charges are recorded in the Acquisition costs and related fair value adjustments and impairment of goodwill and long-lived assets line item in the Consolidated Statements of Operations and reported under the Corporate & Other segment.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill

The annual goodwill impairment assessment was performed as of July 1, 2018, for the year ended September 30, 2018.

The goodwill of acquired companies is primarily related to the acquisition of an experienced and knowledgeable workforce.

A reporting unit represents a component of an operating segment that (a) constitutes a business, (b) has discrete financial information, and (c) has its performance is reviewed by management. During the year ended September 30, 2016, the Company concluded that it had five reporting units—RSCG, CAG, GovDeals, TruckCenter, and IronDirect. During 2017, the Company exited certain TruckCenter operations in order to focus its time and resources on its ecommerce marketplace strategy. As a result, as of September 30, 2017, the Company had four reporting units-RSCG, CAG, GovDeals and IronDirect. As a result of the acquisition of Machinio during the year ended September 30, 2018, the Company had five reporting units-RSCG, CAG, GovDeals, IronDirect, and Machinio at September 30, 2018.

As a result of the Company's 2016 annual impairment assessment, the Company recorded a $19.0 million impairment charge to its RSCG reporting unit. The goodwill impairment was due to updated assumptions used in the fair value calculation.

As part of the Company's 2018 and 2017 annual impairment assessments, the Company determined that certain events required the Company to evaluate goodwill to identify potential impairment. After performing the evaluation, the Company concluded the remaining reporting units with goodwill had fair values as of July 1, 2018 and 2017, that substantially exceeded their respective book values.

The following summarizes the goodwill activity for the Company's reportable segments that have goodwill during the periods indicated:

The Company did not record intangible asset impairment charges in 2018. During 2017, the Company recorded a $1.2 million impairment of a contract intangible associated with customer relationships in its IronDirect business and reduced the remaining unamortized value of this intangible asset to zero. The Company also concluded that a covenant not to compete intangible asset received in connection with the acquisition of the TruckCenter business, was impaired due to the exit of the TruckCenter land-based, live auction and retail business. The Company recorded a $0.1 million charge and reduced the remaining unamortized value of this intangible asset to zero during the year ended September 30, 2017. These impairment charges are recorded in the Acquisition costs and related fair value adjustments and impairment of goodwill and long-lived assets line item in the Consolidated Statements of Operations and reported under the Corporate & other segment.

Leases

The Company leases certain office space and equipment under non-cancelable operating lease agreements, which expire at various dates through 2023. Certain of the leases contain escalation clauses and provide for the pass-through of increases in operating expenses and real estate taxes. Rent related to leases that have escalation clauses is recognized on a straight-line basis. Resulting deferred rent charges are included in other long-term liabilities and were $0.6 million and $0.6 million, at September 30, 2018 and 2017, respectively. Future minimum payments under the leases as of September 30, 2018, are as follows:



Year Ending September 30,	Operating Lease Payments

Total future minimum lease payments	$	11,882

On June 16, 2017 the Company entered into a sub-lease agreement for 18,412 square feet of office space at 6931 Arlington Road, Bethesda, Maryland. The sub-lease commenced September 29, 2017 and will expire April 30, 2023. On the sub-lease commencement date, the Company relocated its headquarters previously located at 1920 L Street NW, Washington DC, to the new Bethesda location. The Company ceased using the L Street location as of September 30, 2017 and recognized a $2.0 million cease-use charge in its consolidated statements of operations at September 30, 2017, within the Other operating expenses line item. During November 2018, based on updated information the Company revised its expectation related to contractual obligations toward the lessor of the Company's previous headquarters. As a result of this updated information, the Company recorded a reduction to its cease-use charge of approximately $0.3 million into its financial statements as of September 30, 2018.

Rent expense for the years ended September 30, 2018, 2017 and 2016, was $10.7 million, $10.8 million, and $11.5 million, respectively. The 2017 rent expense amount does not include the $2.0 million cease-use charge pertaining to the L Street location.

At September 30, 2018 and 2017, the Company had federal and state deferred tax assets of $28.4 million and $45.4 million, respectively, related to available federal and state net operating loss (NOL) carryforwards and other U.S. deductible temporary differences. The NOL carryforwards expire beginning in 2035. At September 30, 2018 and 2017, the Company had deferred tax assets related to available foreign NOL carryforwards of approximately $10.2 million and $9.2 million respectively. All but approximately $0.4 million of our foreign NOLs maintain an indefinite carry forward life. The NOLs with limited carryforward periods will expire beginning in 2019.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“The Tax Act”) was signed into law. The Tax Act reduces the corporate tax rate from 35% to 21%. The rate change is administratively effective at the beginning of the Company’s 2018 fiscal year, using a blended rate of 24.53%. Staff Accounting Bulletin 118 provides guidance on accounting for the tax effects of the Tax Act. To the extent a company’s accounting for certain income tax effects of the Tax Act is incomplete but the Company can determine a reasonable estimate, it must record a provisional estimate in the financial statements. At September 30, 2018, the Company had not yet completed its accounting for the tax effects of the Tax Act; however, in the following cases, the Company has made a provisional estimate of the Tax Act’s effects during 2018. We remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future. However, we are still analyzing certain aspects of the Act and refining our calculations, which could potentially affect the measurement of these balances. The provisional benefit recorded for the remeasurement of our deferred tax balance and recognition of the realizability of deferred tax assets was $10.7 million.

The effect of the international provisions of the Tax Act, which establish a territorial tax system and subject certain foreign earnings on which US tax is currently deferred to a one-time transition tax, is uncertain. We have not sufficiently completed our analysis of earnings and profits from our foreign subsidiaries to reasonably estimate the effects of the one-time transition tax, and therefore, have not recorded provisional amounts. We continue to apply ASC 740 based on the provisions of the tax laws that were in effect immediately prior to the Act being enacted. Because we had previously determined these amounts were indefinitely reinvested, no deferred tax assets have been recorded. We will complete the analysis of the effects of the Tax Act in the first quarter of fiscal year 2019.

The Company assesses available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. A significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-year period ended September 30, 2018. Such objective evidence limits the ability to consider other evidence such as our projections for future growth. On the basis of this evaluation, the Company recorded a net change to its valuation allowance of $15 million to bring the total valuation allowance to $39.4 million at September 30, 2018. The change is comprised of $10.8 million for the remeasurement of deferred tax assets using the lower enacted tax rate, $10.7 million benefit for the recognition of the realizability of deferred tax assets for changes in the Tax Act, $0.7 million resulting from the acquisition of Machinio, netted against a $7.2 million charge for current year NOLs.

On July 10, 2018, the Company acquired 100% of stock of Machinio Corp for approximately $19.9 million dollars cash and Company equity. Under the acquisition method of accounting, the Company recorded a net deferred tax liability of $0.7 million comprised primarily of acquired intangibles netted against NOLs and other deferred assets and recognized a $0.7 million tax benefit from a reduction to its valuation allowance. The total amount of acquired NOLs, which are subject to limitations under Section 382, were approximately $1.8 million.

The Company has not recorded a provision for deferred U.S. tax expense on the undistributed earnings of foreign subsidiaries since the Company intends to indefinitely reinvest the earnings of these foreign subsidiaries outside the U.S. The amount of such undistributed foreign earnings was approximately $7.9 million as of September 30, 2018. As of September 30, 2018, and 2017, approximately $14.4 million and $14.9 million, respectively, of cash and cash equivalents was held overseas and not available to fund domestic operations without incurring taxes upon repatriation.

The following is a tabular reconciliation of the total amounts of unrecognized tax benefits:



	Year Ended September 30, (In thousands)
	2018			2017			2016
Beginning balance at October 1	$	—		$	725		$	—

The Company applies the authoritative guidance related to uncertainty in income taxes. ASC 740 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 resolutions of any related appeals or litigation processes, on the basis of the technical merits. During 2018, the Company did not identify any new uncertain tax positions.

The Company recognizes interest and penalties in the period in which they occur in the income tax provision. During 2018, the Company recorded a charge of $0.1 million for interest related to years 2013 and 2014. 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 U.K. The Company has no open income tax examinations and the statute of limitations for years prior to 2015 is now closed. However, certain tax attribute carryforwards that were generated prior to fiscal year 2015 may be adjusted upon examination by tax authorities if they are utilized.

Stockholders' Equity Note [Abstract]

Equity Transactions

2006 Omnibus Long-Term Incentive Plan

In conjunction with the Company's initial public offering, the board of directors and the Company's stockholders approved the 2006 Omnibus Long-Term Incentive Plan (2006 Plan), on December 2, 2005.

A portion of the options and restricted shares granted to employees vest based on certain performance conditions being satisfied by the Company. Performance-based stock options are tied to the Company's annual performance against pre-established internal targets and the actual payout under these awards may vary from zero to 100% of an employee's target payout, based upon the Company's actual performance during the previous twelve months. The performance-based stock options are also subject to vesting requirements and generally vest when the performance condition has been satisfied. The fair value for stock options granted during the period was estimated at the grant date using the Black-Scholes option pricing model, as described in Note 2, and the Company bases the fair value of restricted shares granted on the closing price of the shares on the grant date. The Company recognizes compensation cost over the requisite service period or when it becomes probable that the performance condition will be satisfied.

Under the 2006 Plan, as amended, 10,000,000 shares of common stock were available for issuance. At September 30, 2014, there were 772,227 shares reserved for issuance in connection with awards under the 2006 Plan. In February 2015, at the Company's annual meeting of stockholders, the stockholders approved an amendment to the 2006 Plan which increased the shares available for issuance under the 2006 Plan by 3,000,000 shares and established a fungible share pool so that awards other than options or stock appreciation rights granted after January 9, 2015, would be counted as 1.5 shares from the shares reserved for issuance under the 2006 Plan. 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, bringing the total number of shares issuable under the 2006 Plan since it was adopted to 16,300,000 shares. At September 30, 2018, 2,721,386 shares were reserved for issuance in connection with awards under the 2006 Plan.

During 2017, the Company issued 218,550 cash-settled stock appreciation rights at a price of $10.30, and 234,313 cash-settled stock appreciation rights were forfeited. During 2018, the Company issued 104,055 cash-settled stock appreciation rights at a price of $4.57, and 415,373 cash-settled stock appreciation rights were forfeited. Stock appreciation rights are recorded as liability awards. 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 Company issues stock appreciation rights where restrictions lapse upon either the passage of time (service vesting), achievement of performance targets, or some combination of these conditions. For those stock appreciation rights with only service conditions, the Company recognizes compensation cost on a straight-line basis over the explicit service period. For awards with both performance and service conditions, the Company starts recognizing compensation cost over the remaining service period, when it is probable the performance condition will be met.

During the year ended September 30, 2018, the Company granted both time-based stock options and performance-based stock options to certain employees. Approximately 671,644 options were granted, including 418,780 options subject to performance-based vesting terms and 252,864 subject to time-based vesting terms over four years. The performance-based options will vest in installments based on average stock price and growth in contribution margin, in each case, subject to each recipient’s continued employment with the Company.

During the year ended September 30, 2018, the Company granted both time-based restricted stock and performance-based restricted stock to certain employees. Approximately 1,282,401 shares of restricted stock were granted, including 915,180 shares subject to performance-based vesting and 367,221 subject to time-based vesting terms over four years. The performance-based restricted stock units will vest in installments based on average stock price and 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.

For those stock options and restricted stock with only service conditions, the Company recognizes compensation cost on a straight-line basis over the explicit service period.

For the years ended September 30, 2018, 2017 and 2016, the Company recorded stock-based compensation of $6.6 million, $7.4 million and $12.3 million, respectively. The total costs related to unvested awards with only service vesting conditions, not yet recognized, as of September 30, 2018 was $5.2 million, which will be recognized over the weighted average vesting period of 48 months. The total costs related to unvested awards with both service and performance vesting conditions, not yet recognized, as of September 30, 2018 was $9.8 million.

The 2006 Plan permits the granting of options to purchase shares of common stock intended to qualify as incentive stock options under the Internal Revenue Code and stock options that do not qualify as incentive stock options ("non-qualified stock options"). The exercise price of each stock option may not be less than 100% of the fair market value of the common stock on the date of grant. However, if a grant recipient, who holds at least 10% of the common stock of the Company, receives an incentive stock option, the exercise price of such incentive stock option may not be less than 110% of the fair market value of the common stock on the date of grant. The term of each stock option is fixed by the compensation committee and may not exceed 10 years from the date of grant.

The compensation committee may also award under the 2006 Plan:


•	restricted stock, which are shares of common stock subject to restrictions;


•	restricted stock units, which are common stock units subject to restrictions;


•	dividend equivalent rights, which are rights entitling the recipient to receive credits for dividends that would be paid if the recipient had held a specified number of shares of common stock;


•	stock appreciation rights, which are rights to receive a number of shares or, in the discretion of the compensation committee and subject to applicable law, an amount in cash or a combination of shares and cash, based on the increase in the fair market value of the shares underlying the right during a stated period specified by the compensation committee;


•	unrestricted stock, which are shares of common stock granted without restrictions as a bonus; and


•	performance and annual incentive awards, ultimately payable in common stock or cash, as determined by the compensation committee (the compensation committee may grant multi-year and annual incentive awards subject to achievement of specified goals tied to business criteria set forth in the 2006 Plan).

Acquisition

In connection with the acquisition of Machinio, the Company issued 248,577 restricted stock awards, 370,370 restricted stock units, and 47,202 options valued in the aggregate at approximately $5.0 million to Machinio's executives and employees. The restricted stock awards and options were issued under the Machinio Corp. 2014 Stock Incentive Plan which was assumed by the Company at acquisition. The restricted stock units were issued through a private placement. The Company also issued 297,014 shares of restricted Company common stock through a private placement to the Machinio executives. Lastly, the Company issued 49,893 restricted stock awards under its 2006 Omnibus Long-Term Incentive Plan to Machinio employees.

Share Repurchase Program

The Board of Directors authorized the Company to repurchase issued and outstanding shares of its common stock under a share repurchase program approved by the 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 the Company's available cash. The Company's Board of Directors reviews the share repurchase program periodically, the last such review having occurred in May 2016. The Company did not repurchase shares under this program during the twelve months ended September 30, 2018. As of September 30, 2018, the Company may repurchase an additional $10.1 million shares under this program.

Fair Value Measurement

Fair Value Disclosures [Abstract]

Fair Value Measurement

The Company measures and records in the accompanying consolidated financial statements certain 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.

As of September 30, 2017, the Company had financial assets that were measured at fair value and were classified as Level 3 assets within the fair value hierarchy. The Company no longer had such assets at September 30, 2018. The Company recorded the financial assets using the fair value option under ASC 825, Financial Instruments. These financial assets represented the value of rights the Company held from its participation in certain principal transactions in the Company's commercial business, where a third-party partner owned the underlying assets to be sold, and the Company had contributed funds to the partner towards purchasing those underlying assets. These assets were included in prepaid expenses and other current assets in the Consolidated Balance Sheets.

During the year ended September 30, 2018, and as a result of the acquisition of Machinio, the Company recorded contingent consideration in the amount of $1.2 million on its balance sheet. This contingent consideration was measured at fair value and classified as Level 3 liabilities within the fair value hierarchy. The contingent consideration is based on the Company's achievement of EBITDA targets for the 12-month period ending December 31, 2019. The liability for this consideration is included in Deferred taxes and other long-term liabilities in the Consolidated Balance Sheets.

During the year ended September 30, 2018, the Company invested $20.0 million in certificates of deposit with maturities of six months or less, and interest rates between 2% and 2.5%. These assets were measured at fair value and were classified as Level 1 assets within the fair value hierarchy.

The changes in financial assets and earn-out liability measured at fair value for which the Company has used Level 3 inputs to determine fair value for the year ended September 30, 2018, are as follows (dollars in thousands):

When valuing its financial assets, the Company considers asset condition, economic and/or market events, and other pertinent information that would impact its estimate of the expected generated proceeds. The valuation procedures are primarily based on management's projection of the value of the assets securing the financial investment.

The Company estimated the fair value of the contingent consideration using a Monte Carlo simulation. The calculation was based on EBITDA volatilities observed in comparable companies in Machinio's industry.

Management’s estimation of the fair value of these assets and liabilities is based on the best information available in the circumstances and may incorporate management's own assumptions regarding market demand for these assets. Such assumptions involve management's judgment, taking into consideration a combination of internal and external factors. Changes in fair value of the Company's Level 1 and Level 3 assets and liabilities are recorded in Other operating expense in the Consolidated Statements of Operations.

The Company’s financial assets 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, and a promissory note. The Company believes the carrying value of these instruments approximates fair value

Defined Benefit Plan [Abstract]

Defined Benefit Pension Plan

Certain employees of Liquidity Services UK Limited ("GoIndustry"), which the Company acquired in July 2012, are covered by the Henry Butcher Pension Fund and Life Assurance Scheme (the "Scheme"), a qualified defined benefit pension plan. The Scheme was closed to new members on January 1, 2002.

The Company recognizes the funded status of its postretirement benefit plans, with a corresponding noncash adjustment to accumulated other comprehensive loss, net of tax, in stockholders' equity. The funded status is measured as the difference between the fair value of the plan's assets and the benefit obligation of the plan.

The net periodic benefit cost recognized for the years ended September 30, 2018, 2017 and 2016, included the following components:

The following table provides a reconciliation of benefit obligations, plan assets, and funded status related to the Company's qualified defined benefit pension plan for the years ended September 30, 2018 and September 30, 2017:

The accrued pension asset of $2.9 million is recorded in Other long-term assets in the Consolidated Balance Sheet. Because the Plan is closed to new participants, the accumulated benefit obligation is equal to the projected benefit obligation, and totals $22.2 million and $25.1 million at September 30, 2018 and September 30, 2017, respectively.

The amount recognized in other comprehensive loss related to the Company's qualified defined benefit pension plan, net of tax, for the years ended September 30, 2018 and September 30, 2017, is shown in the following table:

Estimated amounts to be amortized from accumulated other comprehensive (income) loss into net periodic benefit cost during 2018 based on September 30, 2018 plan measurements are $0. Amortization of a net gain or loss included in accumulated other comprehensive income shall be included as a component of net pension cost for a year if, as of the beginning of the year, that net gain or loss exceeds 10 percent of the greater of the projected benefit obligation or the market-related value of plan assets. The plan complies with the funding provisions of the UK Pensions Act 2004 and the Occupational Pension Schemes Regulations Act 2005. The Company does not plan to make contributions to the plan in the near future.

Actuarial Assumptions

The actuarial assumptions used to determine the benefit obligations at September 30, 2018 and September 30, 2017, and to determine the net periodic (benefit) cost for the year were as follows:

Fair Value Measurements

The investment policy and strategy of the plan assets, as established by the Trustees (the "Trustees") of the plan, strive to maximize the likelihood of achieving primary objectives of the investment policy established for the plan. The primary objectives are:


1.	Funding—to ensure that the Plan is fully funded using assumptions that contain a modest margin for prudence. Where an actuarial valuation reveals a deficit, a recovery plan will be put in place which will take into account the financial covenant of the employer;


2.	Stability—to have due regard to the likely level and volatility of required contributions when setting the Plan's investment strategy; and


3.	Security—to ensure that the solvency position of the Plan is expected to improve. The Trustees will take into account the strength of employer's covenant when determining the expected improvement in the solvency position of the Plan.

The assets are allocated among equity investments and fixed income securities. The assets are not rebalanced but the allocation between equities and bonds is reviewed on a periodic basis to ensure that the investments are appropriate to the Scheme's circumstances. The Trustees review the investment policy on an ongoing basis, to determine whether a change in the policy or asset allocation targets is necessary. The Company has elected to use a bid value of Scheme assets to calculate the expected return on assets in the net periodic benefit cost. The assets consisted of the following as of September 30, 2018:



	Actual 2018
Equity securities	45.7	%
Fixed-income securities	53.1	%
Cash equivalents	1.2	%
Total	100.0	%

The class of equity securities consists of one pooled fund whose strategy is to invest in approximately 70% UK company shares (domestic) and 30% international equity securities. The class of fixed-income securities consists of one pooled fund whose strategy is to invest in a limited number of government and corporate bonds.

The expected long-term rate of return for the plan's total assets is based on the expected returns of each of the above categories, weighted based on the current target allocation for each class. The Trustees evaluate whether adjustments are needed based on historical returns to more accurately reflect expectations of future returns.

The Company is required to present certain fair value disclosures related to its postretirement benefit plan assets, even though those assets are not included on the Company's Consolidated Balance Sheets. The following table presents the fair value of the assets of the Company's qualified defined benefit pension plan by asset category and their level within the fair value hierarchy, which has three levels based on reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets, Level 2 refers to fair values estimated using significant other observable inputs, and Level 3 includes fair values estimated using significant unobservable inputs.

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 Henry Butcher Pension Fund and Life Assurance Scheme (the "Scheme"). 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 Scheme 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. See Note 13 for further information on the Scheme.

Business Realignment Expenses

Restructuring and Related Activities [Abstract]

Business Realignment Expenses

In January 2017, the Company decided to exit the TruckCenter land-based, live auction and retail business. Costs of $0.9 million associated with the restructuring, were recognized under other operating expenses in the consolidated statement of operations. Those costs included occupancy cost of $0.6 million, employee severance of $0.2 million, and long-lived asset impairments of $0.1 million.

During the fourth quarter of 2017, the Company began to restructure its CAG business. The restructuring plan resulted in a reduction in force across a number of departments, including Sales, Marketing and Operations in both the United States and in Europe. In connection with this restructuring, on September 25, 2017 the Company terminated the employment of the President of the CAG business and provided a severance package to the executive in the amount of $0.3 million. Overall, severance costs associated with this restructuring were approximately $0.9 million. In addition, the restructuring plan calls for the closure of several offices and legal entities in Europe and Asia. Legal and administrative costs associated with the restructuring were $0.1 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 therefore completed winding down operations of the Surplus Contract during the year ended September 30, 2018. As a result, the Company recognized an additional $1.7 million in restructuring costs during the year ended September 30, 2018, $1.2 million of which related to severance and occupancy cost as a result of the loss of the Surplus Contract. Restructuring costs associated with the restructuring plan were recognized within the other operating expenses line item in the consolidated statement of operations. This activity is included within employee severance and benefit costs in the table below.

During 2017, the Company reorganized its IronDirect business. As a result, the Company recorded approximately $0.9 million of net expense related to the impairment of long-lived assets associated with the IronDirect business, as well as a fair value adjustment. The impairment was comprised of $1.2 million of impairment related to contract intangibles, and $0.6 million of impairment related to fixed assets. This expense was netted with a $0.9 million reversal of an earn-out liability. In addition to these impairments, and the restructuring of its IronDirect business model, the Company terminated the employment of the IronDirect President and incurred severance costs of approximately $0.1 million, which is included within employee severance and benefit costs in the table below. During the year ended September 30, 2018, the Company recorded restructuring costs of approximately $0.1 million related to occupancy and certain onerous contract costs related to its IronDirect business.

On June 16, 2017 the Company entered into a sub-lease agreement for 18,412 square feet of office space at 6931 Arlington Road, Bethesda, Maryland. The sub-lease commenced September 29, 2017 and will expire April 30, 2023. On the sub-lease commencement date, the Company relocated its headquarters previously located at 1920 L Street NW, Washington DC, to the new Bethesda location. The Company ceased using the previous location as of September 30, 2017 and recognized a $2.0 million cease-use charge in its consolidated statements of operations at September 30, 2017, under the Other operating expenses line item. During November 2018, based on updated information the Company revised its expectation related to contractual obligations toward the lessor of the Company's previous headquarters. As a result of this updated information, the Company recorded a reduction to its cease-use charge of approximately $0.3 million into its financial statements as of September 30, 2018. The amount is presented under occupancy cost in the table below.

During the year ended September 30, 2018, the Company recognized an additional $0.5 million in severance cost primarily related to the restructuring of its Corporate IT department. This is recorded within the Corporate & Other line item below.

The table below sets forth the significant components and activity in the liability for business realignment initiatives during the year ended September 30, 2018, on a segment and consolidated basis:



(in thousands)	Liability Balance at September 30, 2016		Business Realignment Expenses		Cash Payments			Liability Balance at September 30, 2017		Business Realignment Expenses			Cash Payments			Liability Balance at September 30, 2018

Total business realignment	$	—	$	4,223	$	(1,043	)	$	3,180	$	1,942		$	(3,746	)	$	1,376

For the year ended September 30, 2018, the $1.9 million in employee severance and occupancy cost per the table above is recorded in Other operating expenses in the Consolidated Statements of Operations. Of this $1.9 million in cost, approximately $0.6 million is associated with general and administrative, $0.2 million with sales and marketing, and $1.1 million with technology and operations activities.

For the year ended September 30, 2017, the $4.2 million in employee severance and occupancy cost per the table above is recorded in Other operating expenses in the Consolidated Statements of Operations. Of this $4.2 million in cost, approximately $3.7 million is associated with general and administrative, $0.3 million with sales and marketing, and $0.2 million with technology and operations activities.

The Company expects that the majority of the remaining liability balance at September 30, 2018, of approximately $1.4 million will be paid during 2019.

Legal Proceedings	12 Months Ended
Legal Proceedings	Sep. 30, 2018
Loss Contingency, Information about Litigation Matters [Abstract]
Legal Proceedings	Legal Proceedings Howard v. Liquidity Services, Inc., et al., Civ. No. 14-1183 (D. D. C. 2014). On July 14, 2014, Leonard Howard filed a putative class action complaint in the United States District Court for the District of Columbia (the ‘‘District Court’’) against the Company and its chief executive officer, chief financial officer, and chief accounting officer, on behalf of stockholders who purchased the Company's common stock between February 1, 2012, and May 7, 2014. The complaint alleged that the defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 by, among other things, misrepresenting the Company’s growth initiative, growth potential and financial and operating conditions, thereby artificially inflating its stock price, and sought unspecified compensatory damages and costs and expenses, including attorneys’ and experts’ fees. On October 14, 2014, the Court appointed Caisse de Dépôt et Placement du Québec and the Newport News Employees’ Retirement Fund as co-lead plaintiffs. The plaintiffs filed an amended complaint on December 15, 2014, which alleged substantially similar claims, but which did not name the chief accounting officer as a defendant. On March 2, 2015, the Company moved to dismiss the amended complaint for failure to state a claim or plead fraud with the requisite particularity. On March 31, 2016, the Court granted that motion in part and denied it in part. Only the claims related to the Company's retail supply chain group were not dismissed. On May 16, 2016, the Company answered the amended complaint. Plaintiffs’ class certification was granted on September 6, 2017. On June 19, 2018, the parties agreed to settle this action, including to dismiss and release all claims against all defendants, in exchange for the payment by our insurance carriers of $17 million to plaintiffs and the class. The agreement was submitted to the District Court and preliminarily approved on June 20, 2018. The District Court provided final approval of the settlement on October 5, 2018. In re Liquidity Services, Inc. Derivative Litigation, Civ. No. 2017-0080-JTL (Del. Ch. 2017). On February 2, 2017, plaintiff David Girardi filed a putative derivative complaint in the Court of Chancery of the State of Delaware (the “Court of Chancery”), and on February 7, 2017, plaintiff Harold Slingerland filed a putative derivative complaint in the Court of Chancery. On March 9, 2017, plaintiffs Girardi and Slingerland filed a putative consolidated derivative complaint in the Court of Chancery, purportedly on the Company’s behalf. The consolidated complaint named as defendants the Company's Chief Executive Officer and Chief Financial Officer, as well as certain other individuals who served on the Company's Board of Directors between 2012 and 2014, and sought recovery from those individuals, not the Company. The complaint asserted that, among other things, the defendants breached their fiduciary duties to the Company and its stockholders by causing or allowing the Company to make the same misstatements that were alleged in the amended complaint in the Howard action, and for alleged trading in our securities while in possession of material non-public information. The Court of Chancery dismissed the case in November 2017. Following the dismissal of the putative derivative action discussed above, former plaintiffs Girardi and Slingerland sent the Company a letter dated January 5, 2018 (the “Shareholder Demand”) demanding that the Board of Directors take action to remedy purported breaches of fiduciary duties allegedly related to the claims asserted in the above-discussed securities class action and derivative actions. The Company acknowledged receipt of the Shareholder Demand on January 22, 2018. The Company's Board of Directors delegated to a special committee of the Board, comprised of independent directors who are not named in the letter, the tasks of evaluating and formulating recommendations to the Board with respect to, the Shareholder Demand. The special committee retained counsel to assist and advise it in connection with its work. On November 19, 2018, the special committee delivered a report in which it found no basis to assert claims and recommended that the Board not assert claims, against any of the individuals named in the Shareholder Demand. The Company's Board of Directors met on November 27, 2018 to discuss the findings of the special committee, accepted the recommendation of the special committee and determined to reject the demand.

Segment Reporting [Abstract]

Segment Information

The Company provides operating results in five reportable segments: GovDeals, Capital Assets Group (CAG), Retail Supply Chain Group (RSCG), Machinio, and Corporate & Other. However, the GovDeals, Capital Assets Group (CAG), and Retail Supply Chain Group (RSCG) segments constitute 98% of the Company's revenue as of September 30, 2018, and each offers separately branded marketplaces to enable sellers to achieve 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 follows:

•

The GovDeals reportable segment provides self-service solutions 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 services to sellers that includes asset sales and marketing. This segment includes the Company's GovDeals.com and AuctionDeals.com marketplaces.

•

The CAG reportable segment provides full-service solutions to sellers and it consists of marketplaces that enable federal government agencies as well as commercial businesses to sell surplus, salvage, and scrap assets. This marketplace enables federal government agencies as well as commercial businesses to sell scrap assets of the U.S. Department of Defense. This marketplace also provided for the sale of assets procured through our Surplus Contract, which wound down during 2018. CAG also offers a suite of services that includes surplus management, asset valuation, asset sales and marketing. 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 on July 10, 2018.

•

Corporate & Other primarily consists of the Company's IronDirect and TruckCenter operating segments that are not individually significant, as well as elimination adjustments. On January 30, 2017, the Company exited its TruckCenter land-based, live auction business in order to focus its time and resources on its ecommerce marketplace strategy. IronDirect offers 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. Gross profit is calculated as total revenue less cost of goods sold and seller distributions.

The following table sets forth certain financial information for the Company's reportable segments.
