Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Liquidity Services, Inc. (the Company) is a leading global commerce company providing trusted marketplace platforms that power the circular economy. We create a better future for organizations, individuals, and the planet by capturing and unleashing the intrinsic value of surplus. We connect millions of buyers and thousands of sellers through our leading auction marketplaces, search engines, asset management software, and related services. Our comprehensive solutions enable the transparent, efficient, sustainable recovery of value from excess items owned by business and government sellers. Results from our operations are organized into four reportable segments: Retail Supply Chain Group (RSCG), Capital Assets Group (CAG), GovDeals, and Machinio. See Note 14 - Segment Information for more information. We were incorporated in Delaware in November 1999 as Liquidation.com, Inc. and commenced operations in early 2000. On November 1, 2021, the Company purchased all of the issued and outstanding shares of stock of Bid4Assets, Inc. (Bid4Assets), a Maryland corporation based in Silver Spring, MD. Bid4Assets auctions distressed real estate for the federal government, sheriffs, county tax-collectors, financial institutions and real estate funds. See Note 3 - Bid4Assets Acquisition for more information regarding this transaction. 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, including the extent and duration of the COVID-19 pandemic; the Company's susceptibility to rapid technological change; actual and potential competition by entities with greater financial and other resources; and the potential for the commercial sellers from which the Company derives a significant portion of its inventory to change the way they conduct their disposition of surplus assets or to otherwise terminate or not renew their contracts with the Company.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Unaudited Interim Financial Information The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and the rules and regulations of the Securities and Exchange Commission (SEC). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal, recurring adjustments considered necessary for a fair presentation, have been included, and intercompany transactions and accounts have been eliminated in consolidation. The information disclosed in the notes to the condensed consolidated financial statements for these periods is unaudited. Operating results for the three and six months ended March 31, 2022, are not necessarily indicative of the results that may be expected for the year ending September 30, 2022, or for any future period. 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 condensed consolidated financial statements and accompanying notes. For the three and six months ended March 31, 2022, these estimates required the Company to make assumptions about the extent and duration of restrictions on cross-border transactions and the impact of the COVID-19 pandemic on macroeconomic conditions and, in turn, the Company's results of operations. As there remains uncertainty associated with the COVID-19 pandemic, the Company will continue to update its assumptions as conditions change. Actual results could differ significantly from those estimates. Contract Assets and Liabilities Contract assets reflect an estimate of expenses that will be reimbursed upon settlement with a seller. The contract asset balance was $0.8 million as of March 31, 2022, and $0.6 million as of September 30, 2021, and is included in the line item Prepaid expenses and other current assets on the Condensed Consolidated Balance Sheets. Contract liabilities reflect obligations to provide services for which the Company has already received consideration, and generally arise from up-front payments received in connection with Machinio's subscription services. The contract liability balance was $5.1 million as of March 31, 2022, and $4.6 million as of September 30, 2021, and is included in the line item Deferred revenue on the Condensed Consolidated Balance Sheets. Of the September 30, 2021, contract liability balance, $3.4 million was earned as Fee revenue during the six months ended March 31, 2022. Performance obligations for Machinio's subscription services are satisfied over time as the Company provides the services over the term of the subscription. As of March 31, 2022, the Company has a remaining performance obligation of $5.1 million for these subscription services, and the Company expects to recognize the substantial majority of that amount as Fee revenue over the next 12 months. Contract Costs Contract costs relate to sales commissions paid on subscription contracts that are capitalized. Contract costs are amortized over the expected life of the customer contract. The contract cost balance w as $1.8 million a s of March 31, 2022, and $1.6 million as of September 30, 2021, and is included in the line items Prepaid expenses and other current assets and Other assets on the Condensed Consolidated Balance Sheets. Amortization expense was $0.3 million and $0.5 million during the three and six months ended March 31, 2022, and $0.2 million and $0.3 million during the three and six months ended March 31, 2021. Other Assets - Promissory Note On September 30, 2015, the Company sold certain assets related to its Jacobs Trading business to Tanager Acquisitions, LLC (Tanager). In connection with the disposition, Tanager assumed certain liabilities related to the Jacobs Trading business. Tanager issued a $12.3 million five-year interest-bearing promissory note to the Company. On October 10, 2019, the Company entered into a Forbearance Agreement and Amendment to Note, Security Agreement and Guaranty Agreement (the "Forbearance Agreement") with Tanager (now known as Jacobs Trading, LLC) and certain of its affiliates (collectively, "JTC"). In exchange for additional collateral, security, and a higher interest rate, the Company granted JTC a new repayment schedule that requires quarterly payments to be made from August 2020 to August 2023. Upon execution of the Forbearance Agreement, JTC repaid $2.5 million in principal plus $0.4 million in accrued interest. As of March 31, 2021, JTC had repaid $7.7 million of the $12.3 million owed to the Company and had an outstanding principal balance of $4.6 million. On May 12, 2021, the Company entered into the First Amendment to the Forbearance Agreement with JTC, providing JTC with full satisfaction and discharge from its indebtedness upon receipt of a $3.5 million payment made on May 17, 2021. As a result, the Company recorded a $1.1 million loss as a component of Other operating expenses in its Condensed Consolidated Statement of Operations during the three months ended June 30, 2021, representing the difference between the $4.6 million outstanding balance of principal and accrued interest and the $3.5 million payment received. There was no impact on the unaudited financial statements from this transaction as of and for the three and six months ended March 31, 2022, and March 31, 2021 . 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 on the Condensed Consolidated Balance Sheets. The Company releases the funds to the seller, less the Company's commission and other fees due, through Accounts payable after the buyer has accepted the goods or within 30 days, depending on the state where the buyer and seller conduct business. Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash in banks within interest bearing and earnings allowance checking accounts which may at times exceed federally insured limits (FDIC and/or SIPC), and Accounts receivable. The Company deposits its cash in interest bearing checking accounts with financial institutions that the Company considers to be of high credit quality. Additionally, the Company has multiple vendor contracts with Amazon.com, Inc. under which the Company acquires and sells commercial merchandise. The property purchased under these contracts with Amazon.com, Inc. represented 51.7% and 61.2% of consolidated Cost of goods sold for the three months ended March 31, 2022, and 2021, respectively, and 56.0% and 60.6% of consolidated Cost of goods sold for the six months ended March 31, 2022, and 2021, respectively. These contracts are included within the RSCG reportable segment.

Bid4Assets Acquisition

Bid4Assets Acquisition	6 Months Ended
	Mar. 31, 2022
Business Combination and Asset Acquisition [Abstract]
Bid4Assets Acquisition	Bid4Assets Acquisition On November 1, 2021, the Company purchased all of the issued and outstanding shares of stock of Bid4Assets, Inc. (Bid4Assets), a Maryland corporation. Bid4Assets is a leading online marketplace focused on conducting real property auctions for the government, including tax foreclosure sales and sheriff's sales. The results of Bid4Assets' operations are included within our GovDeals reportable segment and reporting unit. As of March 31, 2022 , the Company's purchase price allocation related to this acquisition is preliminary and subject to revisions as additional information is obtained about the facts and circumstances that existed as of the acquisition date. The revisions may have a significant impact on our condensed consolidated financial statements. The allocation of the purchase price will be finalized once all the information that was known and knowable as of the acquisition date is obtained and analyzed, but not to exceed one year from the acquisition date. The primary areas of the purchase price allocation that are not yet finalized relate to income and non-income taxes, and the residual goodwill. The preliminary amounts assigned to intangible assets by type for this acquisition were based upon our valuation model and historical experiences with entities with similar business characteristics. During the three months ended March 31, 2022 , we recorded a measurement period adjustment of $1.1 million for the earn-out consideration fair value with a corresponding increase to goodwill, based on facts and circumstances in existence as of the effective date of the acquisition related to the discount rates associated with the expected earn-out payments. This resulted in a change to the total consideration transferred and goodwill balance seen below as compared to our previously reported preliminary purchase accounting results as of December 31, 2021. The preliminary acquisition date fair value of the consideratio n transferred to the former shareholders of Bid4Assets was approximately $42.7 million consisting of $14.7 million in cash (net of working capital adjustments totaling $0.3 million) and earn-out consideration with a preliminary fair value of $28.0 million. Former s hareholders of Bid4Assets are eligible to receive earn-out consideration of up to $37.5 million in cash, payable based on Bid4Assets' achievement of trailing twelve-month EBITDA targets measured at the end of each calendar quarter until the quarter ended December 31, 2022. The Company's preliminary allocation of the purchase price to the assets acquired and liabilities assumed as of the Bid4Assets acquisition date of November 1, 2021, is as follows: (in thousands) Fair Value Cash and cash equivalents $ 3,576 Intangible assets 16,500 Other assets 346 Total assets acquired 20,422 Payables to sellers 3,715 Operating lease liabilities 204 Deferred tax liabilities 3,724 Total liabilities assumed 7,642 Net identifiable assets acquired $ 12,780 Goodwill 29,960 Total consideration transferred $ 42,739 The excess of purchase consideration over the fair value of assets acquired and liabilities assumed was recorded as goodwill. The goodwill associated with our acquisition includes the acquired assembled work force, and the value associated with the opportunity to leverage the workforce to continue to grow by adding additional customer relationships or new solutions in the future. Based on management's preliminary valuation of the fair value of tangible and intangible assets acquired and liabilities assumed, goodwill of approximately $30.0 million was recorded. The total goodwill arising from the acquisition is included in the GovDeals reportable segment and reporting unit and is not deductible for tax purposes. The known intangible assets acquired were determined to consist of, and preliminarily fair valued at, the following: (in thousands) Useful Life (in years) Fair Value Contract intangibles 8 $ 13,900 Developed software 3 2,200 Trade name 3 400 Total identifiable intangible assets $ 16,500 Contract Intangibles We recorded contract intangibles separately from goodwill based upon determination of the length, strength, and contractual nature of the relationship that Bid4Assets shared with its suppliers. We valued the contract intangibles using the multi-period excess earnings method, an income approach valuation model. The significant assumptions used in the income approach includes estimates about future expected cash flows from supplier contracts, the attrition rate, and the discount rate. We are amortizing the contract intangibles, preliminarily valued at $13.9 million, on a straight-line basis over a useful life of eight years, which is materially consistent with the expected pattern of economic benefit. Developed Software Developed software primarily consists of intellectual property of the Bid4Assets e-commerce marketplace and associated mailing lists. We valued the developed software by applying the relief-from-royalty method, an income approach valuation model. The significant assumptions used in the relief-from-royalty method include estimates about future expected cash flows from the developed software, the royalty rate, the obsolescence factor and the discount rate. We are amortizing the acquired developed technology, preliminarily valued at $2.2 million, on a straight-line basis over a useful life of three years, which is materially consistent with the expected pattern of economic benefit. Trade Name We valued the trade name acquired using a relief-from-royalty method. The significant assumptions used in the relief-from-royalty method include future expected cash flows from the trade name, the royalty rate, and the discount rate. We are amortizing the trade name, preliminarily valued at $0.4 million, on a straight-line basis over a useful life of three years, which is materially consistent with the expected pattern of economic benefit. Contingent Consideration During the six months ended March 31, 2022, and as a result of the acquisition of Bid4Assets, the Company recorded preliminary contingent consideration in the amount of $28.0 million on its Condensed Consolidated Balance Sheets. See further discussion of this matter within Note 11 - Fair Value Measurement . Other Information Revenue, net income (loss), and pro forma information related to the Bid4Assets acquisition was immaterial to the condensed consolidated financial statements and its related notes for the three and six months ended

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic net income per share is computed by dividing net income for the period by the weighted average number of shares outstanding during the period. Diluted net income per share is computed by dividing net income for the period by the weighted average number of shares of common stock and potentially dilutive common stock outstanding during the period. The calculation of diluted net income per share excludes all anti-dilutive common shares.

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesThe Company’s interim effective income tax rate is based on management’s best current estimate of the Company's expected annual effective income tax rate. The Company recorded pre-tax income in the first six months of fiscal year 2022 and its corresponding effective tax rate is 11.7% compared to 6.7% for the first six months of fiscal year 2021. The change in the effective tax rate for the six months ended March 31, 2022, as compared to the same period in the prior year was primarily due to state and foreign taxes, and the utilization of net operating losses. The effective tax rate differed from the U.S. statutory federal rate of 21% primarily as a result of the impact of foreign, state, and local income taxes and permanent tax adjustments. The Company applies the authoritative guidance related to uncertainty in income taxes. ASC 740, Income Taxes

The stock options and RSUs & RSAs containing market conditions will vest upon the achievement of specified increases in the Company’s share price. Vesting is measured the first day of each fiscal quarter over the four-year terms of the awards, starting with the first fiscal quarter after the first anniversary of the grant date, based upon the trailing 20-days average of the Company’s share price. The range of assumptions used to determine the fair value of stock options containing only service conditions using the Black-Sc holes option-pricing model during the six months ended March 31, 2022, were as follows: Six Months Ended March 31, 2022 Dividend yield — Expected volatility 57.0% - 61.2% Risk-free interest rate 1.1% - 1.8% Expected term 4.5 - 7.4 years The range of assumptions used to determine the fair value of stock options and RSUs & RSAs containing market conditions using Monte Carlo simulations during the six months ended March 31, 2022, were as follows: Six Months Ended March 31, 2022 Dividend yield — Expected volatility 57.2% - 62.9% Risk-free interest rate 1.1% - 1.5% Expected holding period (% of remaining term) 29.4% - 100.0% SARs During the six months ended March 31, 2022, the Company did not issue any SARs, 6,725 SARs were exercised requiring the Company to make cash payments of less than $0.1 million, and 3,250 SARs were canceled. As of March 31, 2022 , 32,070 SARs were outstanding. Share Repurchase Program From time to time, we may be authorized to repurchase issued and outstanding shares of our common stock under a share repurchase program approved by our 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 our available cash. The Company had no remaining share repurchase authorization as of September 30, 2021. On December 6, 2021, the Company's Board of Directors authorized a new stock repurchase plan of up to $20 million of the Company's ou tstanding shares of common stock through December 31, 2023. The Company repurchased 1,011,881 shares for $17.0 million, and 1,159,066 shares for $20.0 million during the three and six months ended March 31, 2022, respectively. As of March 31, 2022, the Company had no remaining authorization to repurchase shares.

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement The Company measures and records certain assets and liabilities at fair value on a recurring basis. Authoritative guidance issued by the FASB establishes a fair value hierarchy for those instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s assumptions (unobservable inputs). The hierarchy consists of three levels: Level 1: Quoted market prices in active markets for identical assets or liabilities; Level 2: Inputs other than Level 1 inputs that are either directly or indirectly observable; and Level 3: Unobservable inputs developed using estimates and assumptions developed by the Company, which reflect those that a market participant would use. The Company held no money market funds considered cash equivalents at March 31, 2022, while it held $40.0 million of money market funds considered cash equivalents at September 30, 2021. The decrease in money market funds held during the period was a result of the Company's movement of excess cash balances to higher yield product offerings in interest bearing and earnings allowance checking accounts. There were no money market fund assets to measure at fair value at March 31, 2022. Money market funds held at September 30, 2021, were measured at fair value and classified as Level 1 assets within the fair value hierarchy. There were no transfers between levels during the periods presented. During the three and six months ended March 31, 2022, and as a result of the acquisition of Bid4Assets, the Company recorded preliminary fair value of contingent consideration in the amount of $28.0 million on its Condensed Consolidated Balance Sheets. The contingent consideration is based on Bid4Assets' achievement of trailing twelve-month EBITDA targets measured at the end of each calendar quarter until the quarter ended December 31, 2022. The liability for this consideration is included in Accrued expenses and other current liabilities within the Condensed Consolidated Balance Sheets. The Company fair valued the earn-out consideration using Monte Carlo valuation method. The fair value measurements utilized were classified as Level 3 assets within the fair value hierarchy under the provisions of ASC 820, Fair Value Measurements , and ASC 805, Business Combinations . The significant unobservable inputs used in the fair value measurem ent categorized within Level 3 of the fair value hierarchy included estimated results of operations over the earn-out period, volatility of gross profit and operating expenses, and the discount rate. The earn-out consideration was preliminarily valued at approximately $28.0 million at the acquisition date. Fair value of the earn-out consideration will be remeasured at the end of each calendar quarter until December 31, 2022. The changes in earn-out liability measured at fair value for which the Company has used Level 3 inputs to determine fair value during the three and six months ended March 31, 2022, is as follows (in thousands): Contingent Consideration Balance at September 30, 2021 $ — Earn-out from business acquisition 26,900 Balance at December 31, 2021 $ 26,900 Measurement period adjustment 1,100 Change in fair value (8,500) Balance at March 31, 2022 $ 19,500 During the three months ended March 31, 2022 , we recorded a measurement period adjustment of $1.1 million for the earn-out consideration fair value with a corresponding increase to goodwill, based on facts and circumstances in existence as of the effective date of the acquisition related to the discount rates associated with the expected earn-out payments. See further discussion in Note 3 - Bid4Assets Acquisition . During the three months ended March 31, 2022, the fair value of the earn-out liability was reduced by $8.5 million to $19.5 million, due to a decline in the auction events and transactions that are expected to be completed during the earn-out period ending December 31, 2022. This change resulted from events occurring subsequent to the November 1, 2021, acquisition date and therefore were not known nor knowable at that time. These events include extended timelines to advance legislation that allows for online auctions of foreclosed real estate in certain target markets, and other client specific delays in bringing foreclosed real estate to auction. This change in fair value was recorded as a gain within Fair value adjustment of acquisition earn-outs in the Condensed Consolidated Statements of Operations. The $19.5 million in earn-out liability as of March 31, 2022, is recorded within Accrued expenses and other current liabilities in the Condensed Consolidated Balance Sheets. During the three and six months ended March 31, 2022, Bid4Assets achieved certain of the trailing twelve-month EBITDA targets such that payout totaling $3.5 million to former Bid4Assets shareholders is expected to be made by the Company during the third quarter of fiscal 2022. When valuing its Level 3 liability, management's estimation of fair value is based on the best information available in the circumstances and may incorporate management's own assumptions around market demand which could involve a level of judgment, taking into consideration a combination of internal and external factors. Changes in the fair value of the Company's Level 3 liability are recorded in Other operating (income) expenses in the Condensed Consolidated Statements of Operations. The Company’s financial assets and liabilities not measured at fair value are cash, accounts receivable, and accounts payable. The Company believes the carrying values of these instruments approximate fair value. As of March 31, 2022, the Company had no non-financial instruments measured at fair value on a non-recurring basis other than fair value measurements associated with the preliminary purchase accounting for Bid4Assets.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Mar. 31, 2022
Accounting Policies [Abstract]
Unaudited Interim Financial Information	Unaudited Interim Financial Information
Use of Estimates	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 condensed consolidated financial statements and accompanying notes. For the three and six months ended March 31, 2022, these estimates required the Company to make assumptions about the extent and duration of restrictions on cross-border transactions and the impact of the COVID-19 pandemic on macroeconomic conditions and, in turn, the Company's results of operations. As there remains uncertainty associated with the COVID-19 pandemic, the Company will continue to update its assumptions as conditions change. Actual results could differ significantly from those estimates.
Contract Assets and Liabilities; Contract Costs	Contract Assets and Liabilities Contract assets reflect an estimate of expenses that will be reimbursed upon settlement with a seller. The contract asset balance was $0.8 million as of March 31, 2022, and $0.6 million as of September 30, 2021, and is included in the line item Prepaid expenses and other current assets on the Condensed Consolidated Balance Sheets. Contract liabilities reflect obligations to provide services for which the Company has already received consideration, and generally arise from up-front payments received in connection with Machinio's subscription services. The contract liability balance was $5.1 million as of March 31, 2022, and $4.6 million as of September 30, 2021, and is included in the line item Deferred revenue on the Condensed Consolidated Balance Sheets. Of the September 30, 2021, contract liability balance, $3.4 million was earned as Fee revenue during the six months ended March 31, 2022. Performance obligations for Machinio's subscription services are satisfied over time as the Company provides the services over the term of the subscription. As of March 31, 2022, the Company has a remaining performance obligation of $5.1 million for these subscription services, and the Company expects to recognize the substantial majority of that amount as Fee revenue over the next 12 months. Contract Costs Contract costs relate to sales commissions paid on subscription contracts that are capitalized. Contract costs are amortized over the expected life of the customer contract. The contract cost balance w as $1.8 million a s of March 31, 2022, and $1.6 million as of September 30, 2021, and is included in the line items Prepaid expenses and other current assets and Other assets on the Condensed Consolidated Balance Sheets. Amortization expense was $0.3 million and $0.5 million during the three and six months ended March 31, 2022, and $0.2 million and $0.3 million during the three and six months ended
Other Assets - Promissory Note	Other Assets - Promissory Note On September 30, 2015, the Company sold certain assets related to its Jacobs Trading business to Tanager Acquisitions, LLC (Tanager). In connection with the disposition, Tanager assumed certain liabilities related to the Jacobs Trading business. Tanager issued a $12.3 million five-year interest-bearing promissory note to the Company. On October 10, 2019, the Company entered into a Forbearance Agreement and Amendment to Note, Security Agreement and Guaranty Agreement (the "Forbearance Agreement") with Tanager (now known as Jacobs Trading, LLC) and certain of its affiliates (collectively, "JTC"). In exchange for additional collateral, security, and a higher interest rate, the Company granted JTC a new repayment schedule that requires quarterly payments to be made from August 2020 to August 2023. Upon execution of the Forbearance Agreement, JTC repaid $2.5 million in principal plus $0.4 million in accrued interest. As of March 31, 2021, JTC had repaid $7.7 million of the $12.3 million owed to the Company and had an outstanding principal balance of $4.6 million. On May 12, 2021, the Company entered into the First Amendment to the Forbearance Agreement with JTC, providing JTC with full satisfaction and discharge from its indebtedness upon receipt of a $3.5 million payment made on May 17, 2021. As a result, the Company recorded a $1.1 million loss as a component of Other operating expenses in its Condensed Consolidated Statement of Operations during the three months ended June 30, 2021, representing the difference between the $4.6 million outstanding balance of principal and accrued interest and the $3.5 million payment received. There was no impact on the unaudited financial statements from this transaction as of and for the three and six months ended March 31, 2022, and March 31, 2021
Risk Associated with Certain Concentrations	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 on the Condensed Consolidated Balance Sheets. The Company releases the funds to the seller, less the Company's commission and other fees due, through Accounts payable after the buyer has accepted the goods or within 30 days, depending on the state where the buyer and seller conduct business. Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash in banks within interest bearing and earnings allowance checking accounts which may at times exceed federally insured limits (FDIC and/or SIPC), and Accounts receivable. The Company deposits its cash in interest bearing checking accounts with financial institutions that the Company considers to be of high credit quality.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Adopted In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . The Company adopted the new standard on a prospective basis effective October 1, 2021. This accounting standard has not had a material impact on the Company's condensed consolidated financial statements. Accounting Standards Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 326)
