Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of the Company and Operating Environment	Description of the Company and Operating Environment Astrotech Corporation (Nasdaq: ASTC) (“Astrotech,” “the Company,” “we,” “us” or “our”), a Washington corporation organized in 1984, is an innovative science and technology development and commercialization company that invents, acquires, and commercializes technological innovations sourced from internal research, universities, laboratories, and research institutions, and then funds, manages, and builds start-up companies for profitable divestiture to market leaders to maximize shareholder value. Our Business Segment Information – With the sale of the ASO business unit (see Note 4 ) and the founding of Astral, the Company operates two reportable business units, Astro Scientific and Astral. Since the Company operates in two segments, all financial segment information required by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 280, Segment Reporting (“FASB ASC 280”) can be found in Note 16 Segment Information. Astro Scientific Astro Scientific is a technology incubator that commercializes innovative technologies. Subsidiaries 1 st Detect and Astrogenetix currently reside in Astro Scientific: 1 st Detect 1 st Detect develops, manufactures, and sells chemical analyzers for use in the airport security, military, and breath analysis markets. Our chemical analyzers can identify chemicals with more accuracy and precision than competing analyzers given their extreme sensitivity and specificity. By leveraging a concept from Oak Ridge National Laboratory and a preliminary design initiated by an engagement with the National Aeronautics and Space Administration (“NASA”) to develop a mass spectrometer for the International Space Station, the Company developed a chemical analyzer that enables real-time analytics that we believe to be significantly smaller, lighter, faster, and less expensive than competing analyzers. The majority of revenue in 1 st Detect comes from working as a subcontractor on government contracts. The Company works with prime contractors in adapting our technology to be used in enhancing the government’s detection capabilities for a variety of applications. Our product portfolio currently consists of the following products: • MMS-1000™ - the MMS-1000™ is a small, low-power desktop analyzer designed for the laboratory market. • OEM-1000 - the OEM-1000 is an original equipment manufacturer (“OEM”) component that drives the MMS-1000™. It is designed to be integrated into customers’ packaging and enclosures and to be integrated with application-specific sampling or separation technology. Variants of the OEM-1000 have been selected by our partners for integration with their ancillary instrumentation. • MMS-2000™ - the MMS-2000™ is a process gas monitor that provides real-time measurement of specific chemicals in a process stream. It is built for continuous, autonomous monitoring and recording of any excursions or environmental anomalies that can continuously report the abundance of a set of chemicals in order to optimize yield or identify out-of-spec conditions. • Tracer 1000 MS-ETD™ - the Tracer 1000 MS-ETD™ is an explosives trace detector (“ETD”) with a linear ion trap mass spectrometer and a swab-based thermal desorption sample inlet system. It is designed to replace the current generation of ion mobility spectrometry-based ETD systems installed at airports and other high security facilities globally. • BreathDetect 1000™ - the BreathDetect 1000™ is a mass spectrometry-based instrument that is being used to analyze human breath in real-time, enabling detection of bacterial infections in the respiratory tract within minutes. Astrogenetix Astrogenetix is applying a fast-track, on-orbit discovery platform using the International Space Station to develop vaccines and other therapeutics. NASA has engaged the Center for Vaccine Development at the University of Maryland (“UMD”), one of the leading vaccinology institutions in the world, to research the application of a vaccine for Salmonella . NASA is collaborating with UMD, meaning little investment is required of Astrogenetix at this stage. Astral Images Astral Images sells film-to-digital conversion, high-dynamic range conversion, image enhancement, defect removal, and color correction services. Astral uses its powerful artificial intelligence (“AI”) algorithms to provide automated conversion of television and feature 35mm and 16mm films to the new 4K/HDR format, the standard for the latest generation of digital film distribution to the home. Due to a significant shift in the film scanning industry, most film assets will need to go through an upgrade to the new standard to remain relevant for over-the-top distribution (Netflix, Amazon, Hulu, etc.) as television manufacturers sell more 4K/HDR televisions and consumer demand for such content accelerates. Astral is positioned to be a leader in the digital conversion of feature films, film-based television series, sporting events shot on film, film libraries, and film archives. Astral has introduced to the digital conversion market Black ICE™ for the conversion of black and white film, Color ICE™ for the conversion of color film, and HDR ICE™ for the conversion of color film or digital video to the new HDR format. Astral’s platform technology is also being designed to launch a targeted solution that will convert photographs, negatives, and slides to a digital format while employing its AI algorithms to restore the image to its original condition in automation.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of Astrotech Corporation and its majority-owned subsidiaries that are required to be consolidated. All intercompany transactions have been eliminated in consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that directly affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Management continuously evaluates its critical accounting policies and estimates, including those used in evaluating the recoverability of long-lived assets, recognition of revenue, valuation of inventory, and the recognition and measurement of loss contingencies, if any. Actual results may vary. Revenue Recognition Astrotech recognizes revenue employing several generally accepted revenue recognition methodologies. The methodology used is based on contract type and the manner in which products and services are provided. Revenue for sale of manufactured product is recognized when it is realized or realizable and earned. The Company considers revenue realized or realizable and earned when a firm sales contract or invoice is in place, delivery has occurred or services have been provided, and collectability is reasonably assured. Construction-Type and Production-Type Contracts A portion of the Company’s revenue is derived from contracts to manufacture mass spectrometers to a buyer’s specification. These contracts are accounted for under the provisions of FASB ASC Topic 605-35 “Revenue Recognition: Construction-Type and Production-Type Contracts”. These contracts are fixed-price and are recorded on the percentage of completion basis using the ratio of costs incurred to estimated total costs at completion as the measurement basis for progress toward completion and revenue recognition. Any losses identified on contracts are recognized immediately. Contract accounting requires significant judgment relative to assessing risks, estimating contract costs and making related assumptions for schedule and technical issues. With respect to contract change orders, claims, or similar items, judgment must be used in estimating related amounts and assessing the potential for realization. These amounts are only included in contract value when they can be reliably estimated and realization is probable. The Company enters into fixed-priced subcontracts on government projects that are one to two years long. Revenue from certain long-term, integrated project management contracts to provide new prototypes and completion services is reported on the percentage-of-completion method of accounting. At the outset of each contract, we prepare a detailed analysis of our estimated cost to complete the project, and our progress is based on the percentage of cost incurred. Risks related to service delivery, usage, productivity, and other factors are considered in the estimation process. The recording of profits and losses on long-term contracts requires an estimate of the total profit or loss over the life of each contract. This estimate requires consideration of total contract value, change orders, and claims, less costs incurred and estimated costs to complete. Anticipated losses on contracts are recorded in full in the period in which they become evident. Profits are recorded based upon the total estimated contract profit multiplied by the current percentage complete for the contract. Research and Development Research and development costs are expensed as incurred. Income from the sale of prototype units in 1 st Detect for the years ended June 30, 2017 and 2016 was $12 thousand and $93 thousand , respectively, and was booked as an offset to research and development and will continue to be booked accordingly until the Company transitions to full production. Research and development expenses for the fiscal years ended June 30, 2017 and 2016 were $5.6 million and $6.5 million , respectively. Net Loss per Common Share Basic net loss per common share is calculated by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share would be considered anti-dilutive (see Note 13 ). Cash and Cash Equivalents The Company considers short-term investments with original maturities of three months or less to be cash equivalents. Cash equivalents are comprised primarily of operating cash accounts, money market investments, and certificates of deposits. Accounts Receivable The carrying value of the Company’s accounts receivable, net of the allowance for doubtful accounts, represents their estimated net realizable value. Astrotech estimates the allowance for doubtful accounts based on type of customer, age of outstanding receivable, historical collection trends, and existing economic conditions. If events or changes in circumstances indicate that a specific receivable balance may be unrealizable, further consideration is given to the collectability of those balances, and the allowance is adjusted accordingly. Receivable balances deemed uncollectible are written off against the allowance. The Company anticipates collecting all unreserved receivables within one year. As of June 30, 2017 and 2016 , there was no allowance for doubtful accounts deemed necessary. Inventory The Company computes inventory cost on a first-in, first-out basis, and inventory is valued at the lower of cost or market. The valuation of inventory also requires the Company to estimate obsolete and excess inventory as well as inventory that is not of saleable quality. Property and Equipment Property and equipment are stated at cost. All furniture, fixtures, and equipment are depreciated using the straight-line method over the estimated useful lives of the respective assets, which is generally five years . Purchased software is typically depreciated over three years ; however, Astral’s proprietary software, Astral HDR ICE™, is being depreciated over seven years as this is management’s best estimate of useful life of this platform. Leasehold improvements are amortized over the shorter of the useful life of the improvement or the term of the lease. Repairs and maintenance are expensed when incurred. Impairment of Long-Lived Assets The Company reviews long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. Recoverability of long-lived assets is dependent on a number of conditions, including uncertainty about future events and demand for our services. No impairments were identified in the years ended June 30, 2017 and 2016 . Fair Value of Financial Instruments Astrotech’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, investments, and accrued liabilities. The Company’s management believes the carrying amounts of these assets and liabilities approximates their fair value due to their liquidity. For more information about the Company’s accounting policies surrounding fair value instruments, see Note 9 . Available-for-Sale Investments Investments that are designated as available-for-sale are reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive loss. The Company determines the cost of investments sold based on a first-in, first-out cost basis at the individual security level. The Company’s investments are subject to a periodic impairment review and are evaluated based on the specific facts and circumstances present at the time of assessment, which include the consideration of general market conditions, the duration and extent to which the fair value is below cost, and the Company’s ability and intent to hold the investment for a sufficient period of time to allow for recovery of value in the foreseeable future. The Company also considers specific adverse conditions related to the financial health of, and the business outlook for, the investee, which may include industry and sector performance, changes in technology, operational and financing cash flow factors, and changes in the investee’s credit rating. The Company records other than temporary impairments on marketable equity securities and marketable equity method investments in gains (losses) on equity investments, net of previously recorded gains (losses). For more information on investments, see Note 3 . Held-to-Maturity Investments Investments that are designated as held-to-maturity investments are reported at historical amortized costs. These are investments the Company intends to hold until maturity. The Company’s investments are subject to a periodic impairment review. The Company will write down any investment that the Company does not expect to recover the entire amortized cost basis of the instrument. The Company separates other than temporary impairments into amounts representing credit losses, which are recognized in interest and other net income (expense) items, and amounts related to all other factors, which are recognized in other comprehensive loss. For more information on investments, see Note 3 . Operating Leases The Company leases space under operating leases. Lease agreements often include tenant improvement allowances, rent holidays, and rent escalation clauses, as defined in the respective lease agreements. Most of the Company’s lease agreements include renewal periods at the Company’s option. The Company recognizes rent holiday periods, tenant improvement allowances, and scheduled rent increases on a straight-line basis over the lease term beginning with the date the Company takes possession of the leased property. The Company records tenant improvement allowances and rent holidays as deferred rent liabilities on the consolidated balance sheets and amortizes the deferred rent over the terms of the lease to rent expense on the consolidated statements of operations. Share-Based Compensation The Company accounts for share-based awards to employees based on the fair value of the award on the grant date. The fair value of stock options is estimated using the expected dividend yields of the Company’s stock, the expected volatility of the stock, the expected length of time the options remain outstanding, and the risk-free interest rates. Changes in one or more of these factors may significantly affect the estimated fair value of the stock options. The Company recognizes forfeitures as they occur. The fair value of awards that are likely to meet goals, if any, are recorded as an expense over the vesting period (see Note 11 for more information). Noncontrolling Interest Noncontrolling interest accounting is applied for any entities where the Company maintains more than 50% and less than 100% ownership. The Company clearly identifies the noncontrolling interest in the balance sheets and income statements. The Company also discloses three measures of net loss: net loss, net loss attributable to noncontrolling interest, and net loss attributable to Astrotech Corporation. The Company’s operating cash flows in its consolidated statements of cash flows reflect net loss, while basic and diluted loss per share calculations reflect net loss attributable to Astrotech Corporation. The noncontrolling interest balance of $(40) thousand at June 30, 2016 represents an interest by a minority shareholder in one of the Company’s subsidiaries more fully discussed in Note 5 . Income Taxes The Company accounts for income taxes under the liability method, whereby deferred tax asset or liability account balances are determined based on the difference between the financial statement and the tax bases of assets and liabilities using current tax laws and rates in effect for the year in which the differences are expected to affect taxable income. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. A valuation allowance is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Treasury Stock The Company records treasury stock at the cost to acquire it and includes treasury stock as a component of stockholders’ equity. Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” (Topic 606) (“ASU 2014-09”), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition (as updated by ASU 2015-14 in August 2015, ASU 2016-08 in March 2016, and ASU 2016-20 in December 2016). The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides a five-step process to achieve that core principle. ASU 2014-09 requires disclosures enabling users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. ASU 2014-09 was to be effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. ASU 2015-14 delayed the required adoption date for public entities to periods beginning after December 15, 2017, although early adoption to the original effective date under ASU 2014-09 is permitted. Once implemented, the Company can use one of two retrospective application methods for prior periods. Earlier application is not permitted. The Company has been assessing the impact of the new revenue recognition standard on its relationships with its clients. We have hired an outside consultant to help with the adoption of this standard. The Company is nearly complete with its comprehensive diagnostic of the measurement and recognition provisions of the new standard and is in the process of finalizing its conclusions and policies. The Company plans to adopt this standard in fiscal year 2019. The Company has not yet determined the impacts of all the disclosure requirements and specifically is assessing the manner in which it will disaggregate its revenue to illustrate how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. Additionally, while the Company is in the process of assessing its accounting and forecasting processes to ensure its ability to record, report, forecast, and analyze results under the new standard, it is not expecting significant changes to its business processes or systems. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”). ASU 2016-01 modifies how entities measure equity investments and present changes in the fair value of financial liabilities. Under the new guidance, entities will have to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicality exception. A practicality exception will apply to those equity investments that do not have a readily determinable fair value and do not qualify for the practical expedient to estimate fair value under ASC 820, “Fair Value Measurements,” and as such these investments may be measured at cost. ASU 2016-01 will be effective for the Company’s fiscal year beginning July 1, 2018, and subsequent interim periods. The adoption of ASU 2016-01 is not expected to have an impact on the Company’s financial statements. The Company will adopt this ASU in fiscal year 2019. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. 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, with certain practical expedients available. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing the impact the adoption of ASU 2016-02 will have on its financial statements. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities. For assets held at amortized cost basis, ASU 2016-13 eliminates the probable initial recognition threshold in current generally accepted accounting standards, and, instead, requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net amount expected to be collected. For available-for-sale debt securities, credit losses should be measured in a manner similar to current generally accepted accounting standards; however, ASU 2016-13 will require that credit losses be presented as an allowance rather than as a write-down. ASU 2016-13 affects entities holding financial assets and net investment in leases that are not accounted for at fair value through net income. This amendment affects loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of this standard will have on its financial statements. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). ASU 2016-15 will make eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017. The new standard will require adoption on a retrospective basis unless it is impracticable to apply, in which case it would be required to apply the amendments prospectively as of the earliest date practicable. The Company is currently in the process of evaluating the impact of adoption on its consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting” (“ASU 2017-09”). ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as a modification. The new guidance is expected to reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as a modification. Changes to the terms or conditions of a share-based payment award that do not impact the fair value of the award, vesting conditions and the classification as an equity or liability instrument will not need to be assessed under modification accounting. ASU 2017-09 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The amendments in this update should be applied prospectively to an award modified on or after the adoption date. Accordingly, the adoption of ASU 2017-09 will not have an effect on the Company's historical financial statements. The Company is currently evaluating the effect of this standard on future consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The accounting standard for fair value measurements defines fair value, establishes a market-based framework or hierarchy for measuring fair value, and expands disclosures about fair value measurements. The standard is applicable whenever assets and liabilities are measured and included in the financial statements at fair value. The fair value hierarchy established in the standard prioritizes the inputs used in valuation techniques into three levels as follows: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

In October 2008, the FDIC increased its insurance to $250,000 per depositor. The risk of loss attributable to these uninsured balances is mitigated by depositing funds in what the Company believes to be high credit quality financial institutions. The Company has not experienced any losses in such accounts.

At June 30, 2017 , there was $0.6 million of total unrecognized compensation cost related to non-vested stock option awards, which is expected to be recognized over a weighted average period of 2.7 years. Restricted Stock The Company’s restricted stock activity for the years ended June 30, 2017 and 2016 , was as follows: Shares (In thousands) Weighted Average Grant-Date Fair Value Outstanding at June 30, 2015 336 $ 3.16 Granted 35 2.02 Vested (112 ) 2.79 Canceled or expired (104 ) 3.20 Outstanding at June 30, 2016 155 $ 3.14 Granted 258 1.73 Vested (75 ) 3.17 Canceled or expired (58 ) 2.38 Outstanding at June 30, 2017 280 $ 1.99 Compensation costs recognized related to vested restricted stock awards during the years ended June 30, 2017 and 2016 was $1.0 million and $1.1 million , respectively. At June 30, 2017 , there was $0.2 million of unrecognized compensation costs related to restricted stock, which is expected to be recognized over a weighted average period of 1.4 years. Fair Value of Stock-Based Compensation Stock-based compensation costs are generally based on the fair value calculated from the Black-Scholes model on the date of grant of stock options. The fair values of stock options are amortized as compensation expense on a straight-line basis over the vesting period of the grants. The Company recognizes forfeitures as they occur. The assumptions used for the years ended June 30, 2017 and 2016 and the resulting estimates of weighted-average fair value per share of options granted are summarized in the following table: Year ended Year ended Expected Dividend Yield — % — % Expected Volatility 124 % 109 % Risk-Free Interest Rates 2.42 % 0.65 % Expected Option Life (in years) 6.61 8.71 Weighted-average grant-date fair value of options awarded $ 1.23 $ 1.18 • The expected dividend yield is based on the Company’s current dividend yield and the best estimate of projected dividend yield for future periods within the expected life of the option, which is currently 0% . • The Company estimated volatility using the historical share price performance over the expected life. Management believes the historical estimated volatility is materially indicative of expectations about future volatility. • The estimate of the risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. • For the years ended June 30, 2017 and June 30, 2016 , the Company used the simplified method of calculating the expected life of the options. Securities Repurchase Program On December 13, 2014, the Board of Directors amended the share repurchase program to allow for the repurchase of up to $5.0 million more treasury shares until December 31, 2015. On December 3, 2015, the Board authorized an extension of the share repurchase program through December 31, 2016. At the conclusion of the share repurchase program, the Company had repurchased 188,635 shares of common stock at a cost of $492 thousand , which represents an average cost of $2.61 per share. Shares Repurchased from Related Parties In August 2016, the Company repurchased 192,000 shares issued to the Chief Financial Officer and the Chief Operating Officer related to their tax withholding obligations at a cost of $308 thousand which represents an average price of $1.60 per share. In December 2016, the Company repurchased 601,852 shares from the Chief Executive Officer at a cost of $975 thousand , which represents an average cost of $1.62 per share.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts. Valuation allowances are established, when necessary, to reduce deferred tax assets to amounts that are more likely than not to be realized. As of June 30, 2017 and 2016 , the Company had established a full valuation allowance against all of its net deferred tax assets. For the fiscal year ended June 30, 2017 , the Company incurred losses from operations in the amount of $ 11.8 million . The total effective tax rate is approximately 0% for the fiscal year. There is current state tax expense of approximately $2 thousand . FASB ASC 740, Income Taxes addresses the accounting for uncertainty in income taxes recognized in an entity’s financial statements and prescribes a recognition threshold and measurement attribute for financial statement disclosure of tax positions taken or expected to be taken on a tax return. The Company had no unrecognized tax benefit for the years ended June 30, 2017 and June 30, 2016 . For the years ended June 30, 2017 and 2016 , the Company’s effective tax rate differed from the federal statutory rate of 35% , primarily due to the valuation allowance placed against its net deferred tax assets. Loss carryovers are generally subject to modification by tax authorities until three years after they have been utilized. The components of income tax (expense) benefit from operations are as follows (in thousands): Year Ended June 30, 2017 2016 Current Federal $ — $ 29 State and local (2 ) (4 ) Total tax (expense) benefit $ (2 ) $ 25 A reconciliation of the reported income tax (expense) benefit to the amount that would result by applying the U.S. Federal statutory rate to the loss before income taxes to the actual amount of income tax (expense) benefit recognized follows (in thousands): Year Ended June 30, 2017 2016 Expected benefit $ 3,996 $ 4,576 State tax expense (2 ) (4 ) Change in temporary tax adjustments not recognized (3,905 ) (4,414 ) Other permanent items (91 ) (133 ) Total income tax (expense) benefit $ (2 ) $ 25 The Company’s deferred tax assets as of June 30, 2017 and 2016 consist of the following (in thousands): Year Ended June 30, 2017 2016 Deferred tax assets: Net operating loss carryforwards $ 20,439 $ 15,704 Alternative minimum tax credit carryforwards 857 857 Accrued expenses and other timing 1,344 1,473 Total gross deferred tax assets $ 22,640 $ 18,034 Less — valuation allowance (22,195 ) (17,939 ) Net deferred tax assets $ 445 $ 95 Deferred tax liabilities: Property and equipment, principally due to differences in depreciation $ (445 ) $ (95 ) Total gross deferred tax liabilities $ (445 ) $ (95 ) Net deferred tax assets (liabilities) $ — $ — The Company files consolidated returns for Federal, Florida, and Texas income and franchise taxes. In assessing the need for a valuation allowance, management considers whether it is more likely than not that some portion or all of the net deferred tax assets will be utilized to offset future tax liabilities. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. As of June 30, 2017 , the Company provided a full valuation allowance of approximately $22.2 million against its net deferred tax assets. The valuation allowance increased by approximately $4.2 million for the year ended June 30, 2017 . Since the Company reflects a full valuation allowance against its deferred tax assets, there has been no income tax impact from these changes. At June 30, 2017 , the Company had net operating loss carryforwards of approximately $56.9 million ( $19.3 million , tax effected) for federal income tax purposes that are available to offset future regular taxable income. These net operating loss carryforwards expire between the years 2021 and 2036. Utilization of some of these net operating losses is limited due to the changes in stock ownership of the Company associated with the October 2007 Exchange Offer; as such, the benefit from these losses may not be realized. The Company also has accumulated state net operating loss carryforwards of approximately $26.2 million ( $1.1 million , tax effected) that are available to offset future state taxable income. These net operating loss carryforwards expire between the years 2031 and 2036. These losses may also be subject to utilization limitations; as such, the benefit from these losses may not be realized. The Company has a temporary credit for business loss carryovers that may be utilized to offset its Texas margin tax. The credit amount is $0.5 million ( $0.3 million , tax effected). These credits may be used to offset $13 thousand of state tax liability each year and will expire in 2027. The Company has $0.9 million of alternative minimum tax credit carryforwards available to offset future regular tax liabilities. Uncertain Tax Positions The Company’s change in uncertain tax benefit reserves during 2017 and 2016 were as follows (in thousands): 2017 2016 Balance at July 1 $ — $ 76 Additions for tax positions of current period — — Additions for tax positions of prior years — — Decreases for tax positions of prior years — (76 ) Balance at June 30 $ — $ — During 2016 , the Company removed the uncertain tax benefit reserve of approximately $76 thousand . Due to the statute of limitations in California, the Company can no longer recognize the tax benefit related to state taxes. The Company recognizes interest and penalties related to income tax matters in income tax expense. For the years ended June 30, 2017 and 2016 , the Company did not recognize any interest expense for uncertain tax positions. Furthermore, the Company no longer has a filing requirement in California as of June 30, 2017 .

Earnings Per Share [Abstract]
Net Loss per Share	Net Loss per Share Basic loss per share is computed on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted net income per share is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method and the if-converted method. Dilutive potential common shares include outstanding stock options and shared-based awards. Reconciliation and the components of basic and diluted net loss per share are as follows (in thousands, except per share data): Year Ended 2017 2016 Numerator: Amounts attributable to Astrotech Corporation, basic and diluted: Net loss attributable to Astrotech Corporation $ (11,582 ) $ (13,095 ) Denominator: Denominator for basic and diluted net loss per share attributable to Astrotech Corporation — weighted average common stock outstanding 20,418 20,388 Basic and diluted net loss per common share: Net loss attributable to Astrotech Corporation $ (0.57 ) $ (0.64 ) All unvested restricted stock awards for the year ended June 30, 2017 are not included in diluted net loss per share, as the impact to net loss per share is anti-dilutive. Options to purchase 1,826,264 shares of common stock at exercise prices ranging from $0.32 to $3.20 per share outstanding for the year ended June 30, 2017 were not included in diluted net loss per share, as the impact to net loss per share is anti-dilutive. Options to purchase 957,750 shares of common stock at exercise prices ranging from $0.32 to $3.20 per share outstanding for the year ended June 30, 2016 were not included in diluted net loss per share, as the impact to net loss per share is anti-dilutive.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company currently has two reportable business units: Astro Scientific and Astral. Astro Scientific Astro Scientific is a technology incubator that commercializes innovative technologies. Subsidiaries 1 st Detect and Astrogenetix currently reside in Astro Scientific: 1 st Detect - 1 st Detect develops, manufactures, and sells chemical analyzers for use in the airport security, military, and breath analysis markets. Our chemical analyzers can identify chemicals with more accuracy and precision than competing analyzers given their extreme sensitivity and specificity. By leveraging a concept from Oak Ridge National Laboratory and a preliminary design initiated by an engagement with NASA to develop a mass spectrometer for the International Space Station, the Company developed a chemical analyzer that enables real-time analytics that we believe to be significantly smaller, lighter, faster, and less expensive than competing analyzers. The majority of revenue in 1 st Detect comes from working as a subcontractor on government contracts. The Company works with prime contractors in adapting our technology to be used in enhancing the government’s detection capabilities for a variety of applications. Astrogenetix - Astrogenetix is applying a fast-track, on-orbit discovery platform using the International Space Station to develop vaccines and other therapeutics. NASA has engaged the Center for Vaccine Development at UMD, one of the leading vaccinology institutions in the world, to research the application of a vaccine for Salmonella . NASA is collaborating with UMD, meaning little investment is required of Astrogenetix at this stage. Astral Images Astral Images sells film-to-digital conversion, high-dynamic range conversion, image enhancement, defect removal, and color correction services. Astral uses its powerful artificial intelligence (“AI”) algorithms to provide automated conversion of television and feature 35mm and 16mm films to the new 4K/HDR format, the standard for the latest generation of digital film distribution to the home. Due to a significant shift in the film scanning industry, most film assets will need to go through an upgrade to the new standard to remain relevant for over-the-top distribution (Netflix, Amazon, Hulu, etc.) as television manufacturers sell more 4K/HDR televisions and consumer demand for such content accelerates. Astral is positioned to be a leader in the digital conversion of feature films, film-based television series, sporting events shot on film, film libraries, and film archives. Astral has introduced to the digital conversion market Black ICE™ for the conversion of black and white film, Color ICE™ for the conversion of color film, and HDR ICE™ for the conversion of color film or digital video to the new HDR format. Astral’s platform technology is also being designed to launch a targeted solution that will convert photographs, negatives, and slides to a digital format while employing its AI algorithms to restore the image to its original condition in automation. All intercompany transactions between business units have been eliminated in consolidation. Key financial metrics of the Company’s segments for the years ended June 30, 2017 and 2016 are as follows: Year Ended Year Ended Revenue, Depreciation, and Income Revenue Depreciation Loss before income taxes Revenue Depreciation Loss before income taxes Astro Scientific $ 2,320 390 $ (9,058 ) $ 2,670 398 $ (10,849 ) Astral 8 321 (2,696 ) 1 127 (2,610 ) Total $ 2,328 $ 711 $ (11,754 ) $ 2,671 $ 525 $ (13,459 ) June 30, 2017 June 30, 2016 Assets Fixed Total Capital Expenditures Total Assets Fixed Total Capital Expenditures Total Assets Astro Scientific $ 1,224 468 $ 16,833 $ 1,146 322 $ 28,125 Astral 1,956 31 2,002 2,246 487 2,398 Total $ 3,180 $ 499 $ 18,835 $ 3,392 $ 809 $ 30,523

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On August 24, 2017, the Company received a letter from The NASDAQ Stock Market notifying the Company of its failure to maintain compliance with the $1.00 per share of common stock minimum closing bid price requirement over the preceding 30 consecutive trading days as required by Marketplace Rule 5550(a)(2). The letter stated that the Company has until February 20, 2018 to demonstrate compliance by maintaining a minimum closing bid price of $1.00 per share of common stock for a minimum of 10 consecutive trading days. If the Company cannot demonstrate compliance, further steps may be taken, up to and including the delisting of its common stock from The NASDAQ Capital Market. The Company has not yet determined what action, if any, it will take in response to this letter, although the Company intends to monitor the closing bid price of its common stock between now and February 19, 2018, and to consider available options if its common stock does not trade at a level likely to result in the Company regaining compliance with The NASDAQ Capital Market minimum closing bid price requirement.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of Astrotech Corporation and its majority-owned subsidiaries that are required to be consolidated. All intercompany transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that directly affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Management continuously evaluates its critical accounting policies and estimates, including those used in evaluating the recoverability of long-lived assets, recognition of revenue, valuation of inventory, and the recognition and measurement of loss contingencies, if any. Actual results may vary.
Revenue Recognition	Revenue Recognition Astrotech recognizes revenue employing several generally accepted revenue recognition methodologies. The methodology used is based on contract type and the manner in which products and services are provided. Revenue for sale of manufactured product is recognized when it is realized or realizable and earned. The Company considers revenue realized or realizable and earned when a firm sales contract or invoice is in place, delivery has occurred or services have been provided, and collectability is reasonably assured.
Construction-Type and Production-Type Contracts	Construction-Type and Production-Type Contracts A portion of the Company’s revenue is derived from contracts to manufacture mass spectrometers to a buyer’s specification. These contracts are accounted for under the provisions of FASB ASC Topic 605-35 “Revenue Recognition: Construction-Type and Production-Type Contracts”. These contracts are fixed-price and are recorded on the percentage of completion basis using the ratio of costs incurred to estimated total costs at completion as the measurement basis for progress toward completion and revenue recognition. Any losses identified on contracts are recognized immediately. Contract accounting requires significant judgment relative to assessing risks, estimating contract costs and making related assumptions for schedule and technical issues. With respect to contract change orders, claims, or similar items, judgment must be used in estimating related amounts and assessing the potential for realization. These amounts are only included in contract value when they can be reliably estimated and realization is probable. The Company enters into fixed-priced subcontracts on government projects that are one to two years long. Revenue from certain long-term, integrated project management contracts to provide new prototypes and completion services is reported on the percentage-of-completion method of accounting. At the outset of each contract, we prepare a detailed analysis of our estimated cost to complete the project, and our progress is based on the percentage of cost incurred. Risks related to service delivery, usage, productivity, and other factors are considered in the estimation process. The recording of profits and losses on long-term contracts requires an estimate of the total profit or loss over the life of each contract. This estimate requires consideration of total contract value, change orders, and claims, less costs incurred and estimated costs to complete. Anticipated losses on contracts are recorded in full in the period in which they become evident. Profits are recorded based upon the total estimated contract profit multiplied by the current percentage complete for the contract.
Research and Development	Research and Development Research and development costs are expensed as incurred. Income from the sale of prototype units in 1 st Detect for the years ended June 30, 2017 and 2016 was $12 thousand and $93 thousand , respectively, and was booked as an offset to research and development and will continue to be booked accordingly until the Company transitions to full production.
Net Loss per Common Share	Net Loss per Common Share Basic net loss per common share is calculated by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share would be considered anti-dilutive (see Note 13 ).
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers short-term investments with original maturities of three months or less to be cash equivalents. Cash equivalents are comprised primarily of operating cash accounts, money market investments, and certificates of deposits.
Accounts Receivable	Accounts Receivable The carrying value of the Company’s accounts receivable, net of the allowance for doubtful accounts, represents their estimated net realizable value. Astrotech estimates the allowance for doubtful accounts based on type of customer, age of outstanding receivable, historical collection trends, and existing economic conditions. If events or changes in circumstances indicate that a specific receivable balance may be unrealizable, further consideration is given to the collectability of those balances, and the allowance is adjusted accordingly. Receivable balances deemed uncollectible are written off against the allowance.
Inventory	Inventory The Company computes inventory cost on a first-in, first-out basis, and inventory is valued at the lower of cost or market. The valuation of inventory also requires the Company to estimate obsolete and excess inventory as well as inventory that is not of saleable quality.
Property and Equipment	Property and Equipment Property and equipment are stated at cost. All furniture, fixtures, and equipment are depreciated using the straight-line method over the estimated useful lives of the respective assets, which is generally five years . Purchased software is typically depreciated over three years ; however, Astral’s proprietary software, Astral HDR ICE™, is being depreciated over seven years as this is management’s best estimate of useful life of this platform. Leasehold improvements are amortized over the shorter of the useful life of the improvement or the term of the lease. Repairs and maintenance are expensed when incurred.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. Recoverability of long-lived assets is dependent on a number of conditions, including uncertainty about future events and demand for our services.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Astrotech’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, investments, and accrued liabilities. The Company’s management believes the carrying amounts of these assets and liabilities approximates their fair value due to their liquidity.
Available-for-Sale Investments	Available-for-Sale Investments Investments that are designated as available-for-sale are reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive loss. The Company determines the cost of investments sold based on a first-in, first-out cost basis at the individual security level. The Company’s investments are subject to a periodic impairment review and are evaluated based on the specific facts and circumstances present at the time of assessment, which include the consideration of general market conditions, the duration and extent to which the fair value is below cost, and the Company’s ability and intent to hold the investment for a sufficient period of time to allow for recovery of value in the foreseeable future. The Company also considers specific adverse conditions related to the financial health of, and the business outlook for, the investee, which may include industry and sector performance, changes in technology, operational and financing cash flow factors, and changes in the investee’s credit rating. The Company records other than temporary impairments on marketable equity securities and marketable equity method investments in gains (losses) on equity investments, net of previously recorded gains (losses).
Held-to-Maturity Investments	Held-to-Maturity Investments Investments that are designated as held-to-maturity investments are reported at historical amortized costs. These are investments the Company intends to hold until maturity. The Company’s investments are subject to a periodic impairment review. The Company will write down any investment that the Company does not expect to recover the entire amortized cost basis of the instrument. The Company separates other than temporary impairments into amounts representing credit losses, which are recognized in interest and other net income (expense) items, and amounts related to all other factors, which are recognized in other comprehensive loss.
Operating Leases	Operating Leases The Company leases space under operating leases. Lease agreements often include tenant improvement allowances, rent holidays, and rent escalation clauses, as defined in the respective lease agreements. Most of the Company’s lease agreements include renewal periods at the Company’s option. The Company recognizes rent holiday periods, tenant improvement allowances, and scheduled rent increases on a straight-line basis over the lease term beginning with the date the Company takes possession of the leased property. The Company records tenant improvement allowances and rent holidays as deferred rent liabilities on the consolidated balance sheets and amortizes the deferred rent over the terms of the lease to rent expense on the consolidated statements of operations.
Share-Based Compensation	Share-Based Compensation The Company accounts for share-based awards to employees based on the fair value of the award on the grant date. The fair value of stock options is estimated using the expected dividend yields of the Company’s stock, the expected volatility of the stock, the expected length of time the options remain outstanding, and the risk-free interest rates. Changes in one or more of these factors may significantly affect the estimated fair value of the stock options. The Company recognizes forfeitures as they occur. The fair value of awards that are likely to meet goals, if any, are recorded as an expense over the vesting period (see Note 11 for more information).
Noncontrolling Interest	Noncontrolling Interest Noncontrolling interest accounting is applied for any entities where the Company maintains more than 50% and less than 100% ownership. The Company clearly identifies the noncontrolling interest in the balance sheets and income statements. The Company also discloses three measures of net loss: net loss, net loss attributable to noncontrolling interest, and net loss attributable to Astrotech Corporation. The Company’s operating cash flows in its consolidated statements of cash flows reflect net loss, while basic and diluted loss per share calculations reflect net loss attributable to Astrotech Corporation.
Income Taxes	Income Taxes The Company accounts for income taxes under the liability method, whereby deferred tax asset or liability account balances are determined based on the difference between the financial statement and the tax bases of assets and liabilities using current tax laws and rates in effect for the year in which the differences are expected to affect taxable income. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. A valuation allowance is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized.
Treasury Stock	Treasury Stock The Company records treasury stock at the cost to acquire it and includes treasury stock as a component of stockholders’ equity.
Accounting Pronouncements	Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” (Topic 606) (“ASU 2014-09”), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition (as updated by ASU 2015-14 in August 2015, ASU 2016-08 in March 2016, and ASU 2016-20 in December 2016). The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides a five-step process to achieve that core principle. ASU 2014-09 requires disclosures enabling users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. ASU 2014-09 was to be effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. ASU 2015-14 delayed the required adoption date for public entities to periods beginning after December 15, 2017, although early adoption to the original effective date under ASU 2014-09 is permitted. Once implemented, the Company can use one of two retrospective application methods for prior periods. Earlier application is not permitted. The Company has been assessing the impact of the new revenue recognition standard on its relationships with its clients. We have hired an outside consultant to help with the adoption of this standard. The Company is nearly complete with its comprehensive diagnostic of the measurement and recognition provisions of the new standard and is in the process of finalizing its conclusions and policies. The Company plans to adopt this standard in fiscal year 2019. The Company has not yet determined the impacts of all the disclosure requirements and specifically is assessing the manner in which it will disaggregate its revenue to illustrate how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. Additionally, while the Company is in the process of assessing its accounting and forecasting processes to ensure its ability to record, report, forecast, and analyze results under the new standard, it is not expecting significant changes to its business processes or systems. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”). ASU 2016-01 modifies how entities measure equity investments and present changes in the fair value of financial liabilities. Under the new guidance, entities will have to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicality exception. A practicality exception will apply to those equity investments that do not have a readily determinable fair value and do not qualify for the practical expedient to estimate fair value under ASC 820, “Fair Value Measurements,” and as such these investments may be measured at cost. ASU 2016-01 will be effective for the Company’s fiscal year beginning July 1, 2018, and subsequent interim periods. The adoption of ASU 2016-01 is not expected to have an impact on the Company’s financial statements. The Company will adopt this ASU in fiscal year 2019. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. 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, with certain practical expedients available. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing the impact the adoption of ASU 2016-02 will have on its financial statements. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities. For assets held at amortized cost basis, ASU 2016-13 eliminates the probable initial recognition threshold in current generally accepted accounting standards, and, instead, requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net amount expected to be collected. For available-for-sale debt securities, credit losses should be measured in a manner similar to current generally accepted accounting standards; however, ASU 2016-13 will require that credit losses be presented as an allowance rather than as a write-down. ASU 2016-13 affects entities holding financial assets and net investment in leases that are not accounted for at fair value through net income. This amendment affects loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of this standard will have on its financial statements. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). ASU 2016-15 will make eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017. The new standard will require adoption on a retrospective basis unless it is impracticable to apply, in which case it would be required to apply the amendments prospectively as of the earliest date practicable. The Company is currently in the process of evaluating the impact of adoption on its consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting” (“ASU 2017-09”). ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as a modification. The new guidance is expected to reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as a modification. Changes to the terms or conditions of a share-based payment award that do not impact the fair value of the award, vesting conditions and the classification as an equity or liability instrument will not need to be assessed under modification accounting. ASU 2017-09 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The amendments in this update should be applied prospectively to an award modified on or after the adoption date. Accordingly, the adoption of ASU 2017-09 will not have an effect on the Company's historical financial statements. The Company is currently evaluating the effect of this standard on future consolidated financial statements.
