Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	1. Summary of Significant Accounting Policies  Operations  Perceptron, Inc. (“Perceptron” “we”, “us” or “our”) develops, produces and sells a comprehensive range of automated industrial metrology products and solutio ns to manufacturer s for dimensional gauging, dimensional inspection and 3D scanning products. Our products provide solutions for manufacturing process control as well as sensor and software technologies for non-contact measurement, scanning and inspecti on applications. We also offer v alue added s ervices such as training and customer support services.  Basis of Presentation and Principles of Consolidation  The C onsolidated F inancial S tatements and accompanying notes are prepared in accordance with generally accepted accounting principles in the United State s of America (“U.S. GAAP”). Our Consolidated Financial S tatements include the accounts of Perceptron and our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.  These consolidated financial statements include the results of our acquisitions of Next Metrology Software s.r.o. (“NMS”), which was consummated on January 29, 2015, and Coord3 s.r.l. (“Coord3”), which was consummated on February 27, 2015, from their acquisition dates. See Note 2, “Acquisitions”, below.  Management is required to make certain estimates and assumptions under U.S. GAAP during the preparation of these Consolidated Financial Statements. These estimates and assumptions may affect the reported amounts of assets and liabilities as well as the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.  Revenue Recognition  Revenue related to products and services is recognized upon shipment when title and risk of loss has passed to the customer or upon completion of the service, there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the related receivable is reasonably assured and customer acceptance criteria, if any, have been successfully demonstrated.  We also have multiple element arrangements in our Measurement Solutions product line which may include elements such as, equipment, installation, labor support and/or training. Each element has value on a stand-alone basis and the delivered elements do not include general rights of return. Accordingly, each element is considered a separate unit of accounting. When available, we allocate arrangement consideration to each element in a multiple element arrangement based upon vendor specific objective evidence (“VSOE”) of fair value of the respective elements. When VSOE cannot be established, we attempt to establish the selling price of each element based on relevant third-party evidence. Our products contain a significant level of proprietary technology, c ustomization or differentiation; therefore, comparable pricing of products with similar functionality cannot be obtained. In these cases, we utilize our best estimate of selling price (“BESP”). We determine the BESP for a product or service by considering multiple factors including, but not limited to, pricing practices, internal costs, geographies and gross margin.  For multiple element arrangements, we defer from revenue recognition the greater of the relative fair value of any undelivered elements of the contract or the portion of the sales price of the contract that is not payable until the undelivered elements are completed. As part of this evaluation, we limit the amount of revenue recognized for delivered elements to the amount that is not contingent on the future delivery of products or services, including a consideration of payment terms that delay payment until those future deliveries are completed.  Some multiple element arrangements contain installment payment terms with a final payment (“final buy-off”) due upon the completion of all elements in the arrangement or when the customer’s final acceptance is received. We recognize revenue for each completed element of a contract when it is both earned and realizable. A provision for final customer acceptance generally does not preclude revenue recognition for the delivered equipment element because we rigorously test equipment prior to shipment to ensure it will function in our customer’s environment. The final acceptance amount is assigned to specific element(s) identified in the contract, or if not specified in the contract, to the last element or elements to be delivered that represent an amount at least equal to the final payment amount.  Our Measurement Solutions are designed and configured to meet each customer’s specific requirements. Timing for the delivery of each element in the arrangement is primarily determined by the customer’s requirements and the number of elements ordered. Delivery of all of the multiple elements in an order will typically occur over a three to 15 -month period after the order is received. We do not have price protection agreements or requirements to buy back inventory. Our history demonstrates that sales returns have been insignificant.  Research and Development  In fiscal year 2015 and the first half of fiscal 2016, in connection with our NMS acquisition, costs incurred after technological feasibility for certain new products were capitalized. In the third quarter of fiscal 2016, we recorded an impairment charge of $694,000 for one of these products. The remaining capitalized costs will continue to be amortized to cost of goods sold over the estimated lives of these products. All other research and development costs, including future software development costs, are expensed as incurred. Foreign Currency  The financial statements of our wholly-owned foreign subsidiaries are translated in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 830, “Foreign Currency Translation Matters”. The functional currency of most of our non-U.S. subsidiaries is the local currency. Under this standard, translation adjustments are accumulated in a separate component of shareholders’ equity until disposal of the subsidiary. Gains and losses on foreign currency transactions are included in our Consolidated Statement of Operations under “Foreign currency income (loss), net”.  Earnings Per Share  Basic earnings per share (“EPS”) is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Other obligations, such as stock options and restricted stock awards, are considered to be potentially dilutive common shares. Diluted EPS assumes the issuance of potential dilutive common shares outstanding during the period and adjusts for any changes in income and the repurchase of common shares that would have occurred from the assumed issuance, unless such effect is anti-dilutive. The calculation of diluted shares also takes into effect the average unrecognized non-cash stock-based compensation expense and additional adjustments for tax benefits related to non-cash stock-based compensation expense. Furthermore, we exclude all outstanding options to purchase common stock from the computation of diluted EPS in periods of net losses because the effect is anti-dilutive.  Options to purchase 119,000 , 194,000 and 181,000 shares of common stock, for the fiscal years ended June 30, 201 7 , 201 6 and 201 5 , were not included in the computation of diluted EPS because the effect would have been anti-dilutive.  Cash and Cash Equivalents  We consider all highly liquid investments purchased with maturities of three months or less to be cash equivalents. Fair value approximates carrying value because of the short maturity of the cash equivalents. At June 30, 201 7 , we had $3,704,000 i n cash and cash equivalents of which $3,490,000 was held in foreign bank accounts. We maintain our cash in bank deposit accounts, which, at times, may exceed federally insured limits. We have not experienced any losses in such accounts.  Accounts Receivable and Concentration of Credit Risk  We market and sell our products principally to automotive manufacturers, line builders, system integrators, original equipment manufacturers and value-added resellers. Our accounts receivable are principally from a small number of large customers. We perform ongoing credit evaluations of our customers. Accounts receivable are generally due within 30 to 60 days and are stated at amounts due from customers, net of an allowance for doubtful accounts. Accounts receivable outstanding longer than the contractual payment terms are considered past due. We determine our allowance for doubtful accounts by considering a number of factors, including the length of time trade accounts receivable are past due, our previous loss history, our customer’s current ability to pay their outstanding balance due to us and the conditio n of the general economy and that industry as a whole. We write-off accounts receivable when they become uncollectible; payments subsequently received on such receivables are included in the allowance for doubtful accounts.  Short-Term and Long-Term Investments  We account for our investments in accordance with ASC 320, “Investments – Debt and Equity Securities ”. Investments with a term to maturity between three months to one year are considered short-term investments and are classified as available-for-sale investments. Investments with a term to maturity beyond one year may be classified as available for sale if we reasonably expect the investment to be realized in cash or sold or consumed during the normal operating cycle of the business. Investments are classified as held-to-maturity if the term to maturity is greater than one year and we have the intent and ability to hold such investments to maturity. All investments are initially recognized at fair value. Subsequent measurement for available-for-sale investments is recorded at fair value. Unrealized gains and losses on available-for-sale investments are recorded in other comprehensive income. Held-to-maturity investments are subsequently measured at amortized cost. At each balance sheet date, we evaluate all investments for possible other-than-temporary impairment which involves significant judgment. In making this judgment, we review factors such as the length of time and extent to which fair value has been below the cost basis, the anticipated recovery period, the financial condition of the issuer, the credit rating of the instrument and our ability and intent to hold the investment for a period of time which may be sufficient for recovery of the cost basis. Any losses determined to be other-than-temporary are charged as an impairment loss and recorded in earnings. If market, industry, and/or investee conditions deteriorate, future impairments may be incurred.  Inventory  Inventory is stated at the lower of cost or market. The cost of inventory is determined by the first-in, first-out (“FIFO”) method. We provide a reserve for obsolescence to recognize inventory impairment for the effects of engineering change orders, age and use of inventory that affect the value of the inventory. The reserve for obsolescence creates a new cost basis for the impaired inventory. When inventory that has previously been impaired is sold or disposed of, the related obsolescence reserve is reduced resulting in the reduced cost basis being reflected in cost of goods sold. A detailed review of the inventory is performed annually with quarterly updates for known changes that have occurred since the annual review. Financial Instruments  The carrying amounts of our financial instruments, which include cash and cash equivalents, short-term investments, accounts receivable, accounts payable and amounts due to banks or other lenders, approximate their fair values at June 30, 201 7 and 201 6 . See “Short-Term and Long-Term Investments” for a discussion of our investments. Fair values have been determined through information obtained from market sources and management estimates.  We follow the provisions of ASC 820, “Fair Value Measurements and Disclosures” for all financial assets and liabilities as well as nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. ASC 820 defines fair value, establishes a framework for measuring fair value and required specific disclosures about fair value measurements. Our financial instruments include investments classified as available for sale, mutual funds, fixed deposits and certificate of deposits at June 30, 201 7 .  ASC 820 establishes a hierarchy of valuation techniques based upon whether the inputs to those valuation techniques reflect assumptions other market participants would use based upon market data obtained from independent sources (observable inputs), or reflect our assumptions of market participant valuation (unobservable inputs). These two types of inputs create the following fair value hierarchy:  · Level 1 – Quoted prices in active markets that are unadjusted and accessible at the measurement date for identical, unrestricted assets or liabilities.  · Level 2 – Quoted prices for identical assets and liabilities in markets that are not active, quoted prices for similar assets and liabilities in active markets or financial instruments for which significant inputs are observable, either directly or indirectly.  · Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable and reflect management’s estimates and assumptions.  ASC 820 requires the use of observable market data if such data is available without undue cost and effort.  Property and Equipment  Property and equipment are recorded at historical cost. Depreciation related to machinery and equipment and furniture and fixtures is primarily computed on a straight-line basis over estimated useful lives ranging from 3 to 15 years. Depreciation on buildings is computed on a straight-line basis over 40 years. Depreciation on building improvements is computed on a straight-line basis over estimated useful lives ranging from 10 to 15 years. Our depreciation expense for the years ended June 30, 201 7 , 201 6 , and 201 5 was $1,121,000 , $1,016,000 , and $770,000 , respectively.  Goodwill  Goodwill represents the excess purchase price over the fair value of the net amounts assigned to assets acquired and liabilities assumed in connection with our acquisitions. Under ASC Topic 805 “ Business Combinations” , we are required to test goodwill for impairment annually or more frequently, whenever events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit with goodwill below its carrying amount. Application of the goodwill impairment test requires judgment, including assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units and determination of the fair value of each reporting unit.  The qualitative events or circumstances that could affect the fair value of a reporting unit could include economic conditions; industry and market considerations, including competition; increases in raw materials, labor, or other costs; overall financial performance such as negative or declining cash flows; relevant entity-specific events such as changes in management, key personnel, strategy, or customers; sale or disposition of a significant portion of a reporting unit and regulatory or political developments. Companies have the option under ASC Topic 350 “Intangibles – Goodwill and Other” to evaluate goodwill based upon these qualitative factors, and if it is more likely than not that the fair value of the reporting unit is greater than its carrying amount, then no further goodwill impairment tests are necessary. If the qualitative review indicates it is more likely than not that the fair value of the reporting unit is less than its carrying amount, or if we choose not to perform a qualitative assessment, a two-step quantitative impairment test is performed to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized, if any. During the fourth quarter of fiscal 2017, we completed our goodwill impairment testing by performing a quantitative assessment.  Step 1 is to identify potential impairment by comparing fair value of a reporting unit with its carrying value, including goodwill. If the fair value is lower than the carrying value, this is an indication of goodwill impairment and Step 2 must be performed. Under Step 2, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. This analysis requires significant judgment in developing assumptions, such as estimating future cash flows, which is dependent on internal forecasts, estimating the long-term rate of growth for our business, estimating the useful life over which cash flows will occur and calculating our weighted average cost of capital. The estimates used to calculate the fair value of a reporting unit change from year to year based on operating results, market conditions, foreign currency fluctuations and other factors. Changes in these estimates and assumptions could materially affect the determination of fair value and could result in goodwill impairment for a reporting unit, negatively impacting our results of operations for the period and financial position.  During the fourth quarter of fiscal year 201 7 , we completed Step 1 of our goodwill impairment testing. Based on the results of this test, the fair value of our tested reporting unit exceeded our carrying value by 26% . As a result, no impairment loss was recognized . Goodwill is recorded on the local books of Coord3 and NMS and foreign currency effects will impact the balance of goodwill in future periods. As of June 30, 201 7 , and 2016, our goodwill balance is $7,793,000 and $7,500,000 , respectively, with the increase due to the differences in foreign currency rates at June 30, 201 6 compared to June 30, 201 7 .  Intangible s  We acquired intangible assets in addition to goodwill in connection with the acquisitions of Coord3 and NMS. These assets are susceptible to shortened estimated useful lives and changes in fair value due to changes in their use, market or economic changes, or other events or circumstances. We evaluate the potential impairment of these intangible assets whenever events or circumstances indicate their carrying value may not be recoverable. Factors that could trigger an impairment review include historical or projected results that are less than the assumptions used in the original valuation of an intangible asset, a change in our business strategy or our use of an intangible asset or negative economic or industry trends.  If an event or circumstance indicates that the carrying value of an intangible asset may not be recoverable, we assess the recoverability of the asset by comparing the carrying value of the asset to the sum of the undiscounted future cash flows that the asset is expected to generate over its remaining economic life. If the carrying value exceeds the sum of the undiscounted future cash flows, we compare the fair value of the intangible asset to the carrying value and record an impairment loss for the difference. We generally estimate the fair value of our intangible assets using the income approach based upon a discounted cash flow model. The income approach requires the use of many assumptions and estimates including future revenues and expenses, discount factors, income tax rates, the identification of groups of assets wit h highly independent cash flows and assets’ economic lives. Volatility in the global economy makes these assumptions and estimates more judgmental. Actual future operating results and the remaining economic lives of our other intangible assets could differ from those used in assessing the recoverability of these assets and could result in an impairment of other intangible assets in future periods.  The amortization periods for customer/distributor relationships, trade name and software are five years, ten years and five years, respectively.   Deferred Income Taxes  Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and the effects of operating losses and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for deferred tax assets if it is more likely than not that these items will either expire before we are able to realize their benefit or future deductibility is uncertain (see Note 1 6 “Income Taxes” for further discussion).  Warranty  Our In-Line and Near-Line Measurement Solutions generally carry a one to three -year warranty for parts and a one -year warranty for labor and travel related to warranty. Product sales to the forest products industry carry a three -year warranty for TriCam ® sensors. Sales of ScanWorks ® have a one -year warranty for parts. Sales of WheelWorks ® products have a two -year warranty for parts. We provide a reserve for warranty based on our experience and knowledge. Our Off-Line Measurement Solutions generally carry a twelve -month warranty after the machine passes the acceptance test or a fifteen -month warranty from the date of shipment, whichever date comes first, on parts only.  Factors affecting our warranty reserve include the number of units sold or in-service as well as historical and anticipated rates of claims and cost per claim. We periodically assess the adequacy of our warranty reserve based on changes in these factors. If a special circumstance arises which requires a higher level of warranty, we make a special warranty provision commensurate with the facts.  Self–Insurance  In the U.S. we were self-insured for health and vision costs up to a certain stop-loss level per claim and on an aggregate basis of a percentage of estimated annual costs until December 31, 2016 . Starting January 1, 2017, we went to a fully-insured model for health and vision coverages we offer our U.S employees. We are currently self-insured for any short-term disability claims we may have outstanding.  New Accounting Pronouncements  In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. In March 2016, the FASB issued the final guidance to clarify the principal versus agent guidance (i.e., whether an entity should report revenue gross or net). In April 2016, the FASB issued final guidance to clarify identifying performance obligation and the licensing implementation guidance. In May 2016, FASB updated the guidance in ASU No. 2014-09, which updated implementation of certain narrow topics within ASU 2014-09. Finally, in December 2016, the FASB issued several technical corrections and improvements, which clarify the previously issued standards and corrected unintended application of previous guidance. These standards (collectively “ASC 606”) will be effective for annual periods beginning after December 15, 2017 (as amended in August 2015, by ASU 2015-14, Deferral of the Effective Date), and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the applications of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). We have commenced a detailed analysis of our contracts under ASC 606 and expect to decide which transition method we will utilize to adopt ASC 606 by the end of our second quarter of fiscal 2018 . Based on our preliminary analyses, we expect changes in timing of revenue recognition related to several of our performance obligations; in general, we believe we will be recognizing revenue more quickly than under current revenue recognition guidance. Furthermore, we believe that our Consolidated Balance Sheet will be impacted as we identify Contract Assets and Contract Liabilities. We do not expect a change to the level of disaggregation for our disclosures, although we do expect to provide additional detail about the timing of revenue recognition for several of our performance obligations and about our Contract Assets and Contract Liabilities.  In July 2015, the FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory (ASU 2015-11), which changes the measurement of inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. There were also amendments to the guidance to more clearly articulate the requirements for the measurement and disclosure of inventory. ASU 2015-11 is effective for Perceptron on July 1, 2017 and is not expected to have a significant impact on our consolidated financial statements or disclosures.  In November 2015, the FASB issued Accounting Standards Update No. 2015-17, Balance Sheet Classification of Deferred Taxes (ASU 2015-17), which requires all deferred tax assets and liabilities, included related valuation allowances, be classified as non-current on our consolidated balance sheets. ASU 2015-17 is effective b eginning July 1, 2017 and is expected to result in reclassification on our balance sheet.  In January 2016, the FASB issued Accounting Standards Update No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01), which amends certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASC 2016-01 is effective beginning for Perceptron on July 1, 2018 and is not expected to have a significant impact on our consolidated financial statements or disclosures.  In February 2016, the FASB issued Accounting Standards Update No. 2016-02 Leases (ASU 2016-2), which establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. A modified retrospective transition approach is required for lessees with capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We are currently evaluating the impact of the adoption of ASU 2016-02 on our consolidated financial statements.  In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09), which changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU 2016-09 is effective for fiscal years and interim periods beginning after December 15, 2016, with early adoption permitted . Due to the fact our US Federal Deferred Taxes have a full Valuation Allowance, ASU 2016-09 is not expected to have a significant impact on our consolidated financial statements.  In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments – Credit Losses (Topic 326) (ASU 2016-13), which requires the measurement of all expected credit losses for financial assets held at the reporting date to be based on historical experience, current conditions as well as reasonable and supportable forecasts. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019 including interim periods within those fiscal years, with early adoption permitted. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements.  In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15), which 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 Perceptron beginning on July 1, 2018 and requires us to utilize a retrospective adoption unless it is impracticable for us to apply, in which case, we would be required to apply the amendment prospectively as of the earliest date practicable. We are currently evaluating the impact of the adoption of ASU 2016-15 on our consolidated statement of cash flows.  In October 2016, the FASB issued Accounting Standards Update No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (ASU 2016-16), which requires that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. ASU 2016-16 is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance. We are currently evaluating the impact of the adoption of ASU 2016-16 on our consolidated financial statements.  In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18), which requires a company to present their Statement of Cash Flows including amounts generally described as restricted cash or restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted. We are currently evaluating the impact of the adoption of ASU 2016-18 on our consolidated statement of cash flows.  In January 2017, the FASB issued Accounting Standards Update No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (ASU 2017-01), which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 is effective for Perceptron on July 1, 2018 and is not expected to have a significant impact on our consolidated financial statements or disclosures.  In January 2017, the FASB issued Accounting Standards Update No. 2017-04, Intangibles—Goodwill and Other (Topic 350) (ASU 2017-04), which simplifies the Test for Goodwill Impairment. No. 2017-04 is effective for annual reporting periods beginning after December 15, 2019 with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the impact of the adoption of ASU 2017-04 on our consolidated financial statements and disclosures.  In February 2017, the FASB issued Accounting Standards Update No. 2017-05, Other Income—Gains and Losses from the Derecogn

Acquisitions [Abstract]
Acquisitions	2. Acquisitions  In accordance with ASC Topic 805, “Business Combinations” , we account for acquisitions by applying the acquisition method of accounting. The acquisition method of accounting requires, among other things, that the assets acquired and liabilities assumed in a business combination be measured at their fair values as of the closing date of the acquisition.  The acquisitions of NMS and Coord3 have been accounted for as business combinations. In October 2016, we finalized a settlement with the previous owner of Coord3, who was terminated in connection with the financial improvement plan announced in the third quarter of fiscal 2016. This settlement resolved all open claims between the parties related to our acquisitions of NMS and Coord3, as well as his claims for severance payments. The accompanying Consolidated Statement of Operations for the fiscal year ended June 30, 2015, the year in which the acquisition occurred, includes revenue of $5,639,000 and a net loss of $532,000 related to the operations of NMS and Coord3 subsequent to the dates each acquisition closed. NMS  On January 29, 2015, we acquired 100% of the outstanding share capital of NMS. NMS is a developer of coordinate measuring machine (“CMM”) operating software, based in Prague, Czech Republic. The primary reason for the acquisition was to expand and diversify our offerings in the industrial metrology market, particularly in the scanning CMM market. The total consideration payable in the acquisition of NMS was €2,150,000 (equivalent to approximately $2,445,000 ). We paid €1,800,000 (equivalent to approximately $2,050,000 ) on January 29, 2015, €250,000 (equivalent to approximately $282,000 ) on February 27, 2015 and €100,000 (equivalent to approximately $113,000 ) on February 1, 2016. Coord3  On February 27, 2015, we acquired 100% of the outstanding share capital of Coord3, a subsidiary of Coord3 Industries s.r.l. Coord3 is an Italian-based supplier of a full range of CMM with a global customer base. By combining the full range of Coord3's CMM with our laser scanners and NMS’s CMM operating software, we are able to offer a price competitive, fully integrated scanning CMM solutions’ worldwide. The total consideration p aid in the acquisition of Coord3 was €1,759,200 (equivalent to approximately $2,007,000 ). We paid €1,659,200 (equivalent to approximately $1,893,000 ) on February 27, 2015 and i n October 2016, we finalized a settlement w ith the previous owner , who was terminated in connection with the financial improvement plan announced in the third quarter of fiscal 2016. As part of the settlement, we agreed to a final cash payment of €100,000 (equivalent to approximately $114,000 ) , and wrote off receivables due from an ent ity under his control which resolved all open claims between the parties related to our acquisitions of NMS and Coord3, as well as his claims for severance payments.  We acquired current and long-term taxes payable as part of the purchase of Coord3. The tax liabilities represent income and payroll related taxes that are payable in accordance with government authorized installment payment plans. These installment plans require varying monthly payments through January 2021.  Other long-term liabilities include $614,000 of long-term contractual and statutory severance liabilities acquired as part of the purchase of Coord3 that represent amounts that will be payable to employees upon termination of employment.  Pro forma Information The following unaudited pro forma information for our fiscal year 2015 is based on the assumption that the acquisitions of NMS and Coord3 occurred on July 1, 201 4 , respectively (in thousands, except per share amounts):    2015  Revenue $ 84,091  Net Income (Loss) $ (470)   Income (Loss) Per Common Share  Basic $ (0.05)  Diluted $ (0.05)  As of June 30, 2015, the year in which the acquisitions occurred, we incurred acquisition related costs of approximately $1,600,000 for legal, accounting and valuation consulting fees which are included in “Selling, general and administrative expenses” on our Consolidated Statement of Operations.  These pro forma results of operations have been prepared for comparative purposes only and they do not purport to be indicative of the results of operations that actually would have resulted had the acquisitions occurred on the date indicated or that may result in the future.

Information About Major Customers [Abstract]
Information About Major Customers	3 . Information About Major Customers  Our sales efforts for in-line and near-line products are led by account teams that focus on automotive OEMs. These products are typically purchased for installation in connection with retooling programs undertaken by these companies. Because sales are dependent on the timing of customers’ retooling programs, sales by customer vary significantly from year to year, as do our largest customers.  For the fiscal years 2017, 2016 and 2015, approximately 36% , 34% and 40% , respectively, of our “Net Sales” on our consolidated statements of operations were derived from sales directly to our four largest automotive end-user customers. We also sell to manufacturing line builders, system integrators or assembly equipment manufacturers, who in turn sell to our automotive customers. For the fiscal years 2017, 2016 and 2015, approximately 11% , 8% and 10% , respectively , of net sales were to manufacturing line builders, system integrators and original equipment manufacturers for the benefit of the same four largest automotive end user customers in each respective year. During the fiscal years ended June 30, 201 7 , 201 6 and 201 5 , direct sales to Volkswagen Group accounted for approximately 16% , 17% and 20% , respectively of our total net sales and General Motors Company accounted for approximately 14% , 12% and 12% , respectively of our total net sales.

The change in the gross carrying value of $169,000 is due to changes in foreign currency rates from June 30, 2016 to June 30, 2017. During the third quarter of fiscal 2016, we determined that one of our product lines was not viable in the market. As a result of this determination, the unamortized software development costs associated with this product line was written off in the amount of $694,000 and included in “Severance, Impairment and Other Charges” on our Consolidated Statement of Operations (see Note 1 0 for further discussion).  The estimated amortization of the remaining intangible assets by year is as follows (in thousands):       Years Ending June 30, Amount  2018 1,107  2019 1,096  2020 688  2021 253  2022 253  after 2022 676  $ 4,073  Collectively, the weighted average amortization period of intangible assets subject to amortization is approximately 3.7 years. The intangible assets are amortized over the period of economic benefit or on a straight line basis.

Short-Term And Long-Term Investments [Abstract]
Short-Term And Long-Term Investments	7. Short-Term and Long-Term Investments  As of June 30, 2017 and 2016 , we held short-term restricted cash and at June 30, 2016 we also held l ong-term bank guarantees. The restricted cash and guarantees provide financial assurance that we will fulfill certain customer obligations in China. The cash is restricted as to withdrawal or use while the related bank guarantee is outstanding. Interest is earned on the restricted cash and recorded as interest income. As of June 30, 2017 and June 30, 2016 we had short-term bank guarantees of $239,000 and $77,000 respectively, and long-term bank guarantees of zero and $45,000 respectively.  At June 30, 201 7 , we held a long-term investment in preferred stock that is not registered under the Securities Act of 1933 and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. The preferred stock investment is currently recorded at $725,000 after consideration of impairment charges recorded in fiscal 2008 and 2009. We estimated that the fair market value of this investment at June 30, 201 7 exceeded $ 725,000 based on an internal valuation model which included the use of a discounted cash flow model. The fair market analysis considered the following key inputs, (i) the underlying structure of the security; (ii) the present value of the future principal discounted at rates considered to reflect current market conditions; and (iii) the time horizon that the market value of the security could return to its cost and be sold. Under ASC 820, “Fair Value Measurements” , such valuation assumptions are defined as Level 3 inputs.

Severance, Impairment And Other Charges [Abstract]
Severence, Impairment And Other Charges	10 . Severance, Impairment and Other Charges  During the third quarter of fiscal 2016, we announced a financial improvement plan that resulted in a reduction in global headcount of approximately 11% . This plan was implemented to re-align our fixed costs with our near-to mid-term expectations for our business. In addition, during the first quarter of fiscal 2017, we decided to terminate production and marketing of a specific product line due to limitations in its design. As a result of this decision , we have written off $307,000, net related to inventory and impaired certain customer receivable balances in the amount of $169,000. Total pre-tax cash and non-cash charges related to the original restructuring plan as well as the additional charges from the terminated product line are expected to be up to $4.0 million ; as of June 30, 2017, we have incurred $3,603,000 .  In July 2017, we announced that we had entered into an agreement to settle the civil suit that was filed by 3CEMS, a Cayman Island and People’s Republic of China corporation, in January 2015 (see Note 12 ‘Commitments and Contingencies – Legal Proceedings’ for further discussion). The settlement of $1,000,000 has been recorded as a liability at June 30, 2017.

Credit Facilities [Abstract]
Credit Facilities	11 . Credit Facilities  We had approximately $1,705,000 in our line of credit and short -term notes payable outstanding at June 30, 201 7 and $200,000 in short-term notes payable outstanding at June 30, 201 6 . In addition, w e had approximately $171,000 of long-term debt outstanding at June 30, 201 7 and $365,000 of long-term debt outstanding at June 30, 201 6, which is included in “Other Long-Term Liabilities” on our Consolidated Balance Sheet.  On May 4 , 201 7 , we entered into a Ninth Amendment to the Amended and Restated Credit Agreement with Comerica Bank (the “Credit Agreement”). The Credit Agreement is an on-demand line of credit . The Credit Agreement is cancelable at any time by either Perceptron or Comerica and any amounts outstanding would be immediately due and payable. The maximum permitted borrowings are $6.0 million. The borrowing base is equal to the lesser of (i) $6.0 million or (ii) the sum of 80% of eligible accounts, plus the lesser of 50% of eligible inventory or $2.5 million . At June 30, 201 7 , our additional available b orrowing under this facility was approximately $4.5 million. Proceeds under the Credit Agreement may be used for working capital and capital expenditures. Security for the Credit Agreement is substantially all of our assets held in the United States. Borrowings are designated as a Libor-based Advance or as a Prime-based Advance if the Libor-based Advance is not available. Interest on Libor-based Advances is calculated at 2.35% above the Libor Rate offered at the time for the period chosen, and is payable on the last day of the applicable period. We are required to maintain a Tangible Net Worth of at least $29.0 million . We were in compliance with this Tangible Net Worth covenant at June 30, 2017, however, in August 2017, Comerica provided us a covenant waiver allowing us to complete an internal recapitalization transaction . We are not allowed to pay cash dividends under the Credit Agreement. We are also required to have no advances outstanding under the Credit Agreement for 30 days (which need not be consecutive) during each calendar year. We had $1,500,000 and zero in borrowings outstanding under the Credit Agreement a t June 30, 2017 and 2016 , respectively.  At June 30, 2017, our German subsidiary (“ Perceptron GmbH”) had an unsecured credit facility totaling €350,000 (equivalent to approximately $388,000 ). The facility allows €100,000 to be used to finance working capital needs and equipment purchases or capital leases. The facility allows up to €250,000 to be used for providing bank guarantees. The interest rate on any borrowings for working capital needs is 3.73% . Amounts exceeding €100,000 will bear interest at 6.63% . Any outstanding bank guarantees bear a 2.0% interest rate . The Perceptron GmbH credit facility is cancelable at any time by either Perceptron GmbH or the bank and any amounts then outstanding would become immediately due and payable. At June 30, 201 7 and 20 16 , Perceptron GmbH had no borrowings or bank guarantees outstanding. This credit facility was cancelled in the first quarter of fiscal 2018 at the request of the lender.  During the third quarter of fiscal 2016, our Italian subsidiary, Coord3, exercised an option to purchase their current manufacturing facility. The total remaining principal payments of € 330,000 (equivalent to approximately $376,000 ) payable over the following 22 months at a 7.0% annual interest rate are recorded in “Short-term notes payable” and “Other Long-Term Liabilities” on our Consolidated Balance Sheet at June 30, 201 7 .  Our Brazilian subsidiary (“Brazil”) has several credit lines and overdraft facilities with their current local bank. B razil can borrow a total of B$190,000 (equivalent to approximately $58,000 ). The Brazil facilities are cancelable at any time by either Brazil or the bank and any amounts then outstanding would become immediately due and payable. The monthly interest rates f or these facilities range from 5.14% to 12.85% . We had no borrowings under these facilities at June 30, 2017 and 2016 , respectively.

Commitments And Contingencies [Abstract]
Commitments And Contingencies	12 . Commitments and Contingencies  Leases  We lease building space, office equipment and motor vehicles under operating leases. Lease terms generally cover periods from two to five years and may contain renewal options. The following is a summary, as of June 30, 2017, of the future minimum annual lease payments required under our operating leases having initial or remaining non-cancelable terms in excess of one year (in thousands) :    Years Ending June 30, Minimum Rentals  2018 $ 915  2019 318  2020 40  2021 2  2022 and beyond -  $ 1,275  Re ntal expenses for operating leases i n the fiscal years ended June 30, 2017, 2016 and 2015 were $943,000 , $1,097,000 and $1,007,000 , respectively.  Legal Proceedings  We may, from time to time, be subject to litigation and other claims in the ordinary course of our business. We accrue for estimated losses arising from such litigation or claims if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. To estimate whether a loss contingency should be accrued by a charge to income, we evaluate, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of the loss. Since the outcome of litigation and claims is subject to significant uncertainty, changes in the factors used in our evaluation could materially impact our financial position or results of operations.  We are currently unaware of any significant pending litigation affecting us other than the matters set forth below.  We were a party to a civil suit filed by 3CEMS, a Cayman Islands and People’s Republic of China corporation, in the U.S. District Court for the Eastern District of Michigan and served on us on or about Ja nuary 7, 2015. The suit alleged that we breached our contractual obligations by failing to pay for component parts to be used to manufacture optical video scopes for our discontinued Commercial Products Business Unit. 3CEMS alleged that it purchased the component parts in advance of the receipt of orders based upon instructions they claimed to have received from us. The suit alleged damages of not less than $4.0 million. In July 2017, we entered into an agreement with 3CEMS to settle this suit. As part of the settlement, we agreed to pay 3CEMS $1,000,000 in four equal payments of $250,000 each over a period of ten months beginning in August 2017 (see Note 10 ‘Severance, Impairment and Other Charges’ for further discussion).  In May 2017, a judge in a trade secrets case brought by Perceptron granted the defendants’ motions for summary disposition. The defendants have filed motion s requesting recovery of their attorney fees in the amount of approximately $800,000 , with a hearing scheduled for mid-September 2017 . We are appealing the court’s decision to grant summary disposition and intend to vigorously defend against the defendants’ motion to recover fees. Because of the inherent uncertainty of litigation and claims such as this, we are unable to reasonably estimate a possible loss or range of loss related to the motion to recover fees .  As part of routine evaluation procedures, we identified a potential concern regarding the employment status and withholding for several individuals in one of our foreign jurisdictions. During fiscal 2015, we estimated a range of the potential financial liability related to this matter of € 486,000 to € 1 million. We were not able to reasonably estimate the amount within this range that we would be required to pay for this matter. As a result, in fiscal 2015, we recorded a reserve of €486,000 (equivalent to approximately $522,000 ) representing the minimum amount we estimated would be paid. In the fourth quarter of fiscal 2016, we received the final notice regarding this issue, and as a result, we recorded an additional expense of €227,000 (equivalent to app roximately $244,000 ) . During fiscal 2017, we paid €112,000 (equivalent to app roximately $128,000 ). We currently expect to remit the remaining funds due of € 115,000 (equivalent to app roximately $131,000 ) by the end of our fiscal 2018.

Employee Stock Puchase Plan [Abstract]
Employee Stock Purchase Plan	14 . Employee Stock Purchase Plan  We have an Employee Stock Purchase Plan for all U.S.-based employees meeting certain eligibility criteria. Under the Plan, eligible employees may purchase shares of our common stock at 85% of the market value at the beginning of a six-month election period. Purchases are limited to 10% of an employee's eligible compensation and the shares purchased are restricted from being sold for one year from the purchase date. At June 30, 201 7 , 129,552 shares remained available under the Plan.  Activity under this Plan is shown in the following table (in thousands, except per share amount) :      Purchase Period Ended  June 30,  2017 2016 2015  Non-cash stock based compensation expense $ 4 $ 19 $ 14  Common shares purchased 4 2 3  Average purchase price per share $ 3.86 $ 8.50 $ 10.67 

Stock-Based Compensation

Stock-Based Compensation [Abstract]
Stock-Based Compensation	15 . Stock Based Compensation  We maintain a 2004 Stock Incentive Plan (“2004 Plan”) covering substantially all company employees, non-employee directors and certain other key persons. All Options previously granted under a 1998 Global Team Member Stock Option Plan (“1998 Plan”) were exercised, cancelled or expired before March 31, 2017. The 2004 Plan is administered by a committee of our Board of Directors: The Management Development, Compensation and Stock Option Committee.  Awards under the 2004 Plan may be in the form of stock options, stock appreciation rights, restricted stock or restricted stock units, performance share awards, director stock purchase rights and deferred stock units; or any combination thereof. The terms of the awards are determined by the Management Development, Compensation and Stock Option Committee, except as otherwise specified in the 2004 Plan.  Stock Options  Options outstanding under the 2004 Plan generally become exercisable at 25% or 33 1/3 % per year beginning one year after the date of grant and expire ten years after the date of grant. Option prices from options granted under this plan must not be less than fa ir market value of our stock on the date of grant. We use the Black-Scholes model for determining stock option valuations. The Black-Scholes model requires subjective assumptions, including future stock price volatility and expected time to exercise, which affect the calculated values. The expected term of option exercises is derived from historical data regarding employee exercises and post-vesting employment termination behavior. The risk-free rate of return is based on published U.S. Treasury rates in effect for the corresponding expected term. The expected volatility is based on historical volatility of our stock price. These factors could change in the future, which would affect the stock-based compensation expense in future periods.  We recognized operating expense for non-cash stock-based compensation costs related to stock options in the amount of $374,000 , $428,000 and $298,000 for the fiscal years ended June 30, 201 7 , 201 6 and 201 5 , respectively. As of June 30, 201 7 , the total remaining unrecognized compensation cost related to non-vested stock-based compensation amounted to $556,000 . We expect to recognize this cost over a weighted average vesting period of 2.0 years.  We received $141,000 in cash from option exercises under all stock option payment arrangements for the twelve months ended June 30, 201 7 . The actual tax benefit realized related to tax deductions for non-qualified options exercised and disqualifying dispositions under all stock option payment arrangements totaled approximately $20,000 for fiscal 201 7 .

The total intrinsic value of stock options exercised during the fiscal years ended June 30, 201 7 , 201 6 and 201 5 , were $58,000 , $24,000 and $641,000 , respectively. The total fair value of shares vested during the fiscal years ended June 30, 201 7 , 201 6 and 201 5 , were $409,000 , $323,000 and $295,000 , respectively.  The estimated fair value as of the date options were granted during the periods presented using the Black-Scholes option-pricing model, was as follows:    2017 2016 2015  Weighted average estimated fair value per  share of options granted during the period $ 3.02 $ 2.94 $ 4.04  Assumptions:  Dividend yield - - -  Common stock price volatility 48.25% 45.43% 46.85%  Risk free rate of return 1.81% 1.55% 1.62%  Expected option term (in years) 5.5 5.7 5.8   The following table summarizes information about stock options at June 30, 201 7 :     Options Outstanding Options Exercisable  Weighted Weighted Weighted  Average Average Average  Remaining Exercise Exercise  Range of Exercise Prices Shares Contractual Life Price Shares Price   $ 2.80 to $ 4.87 40,400 5.21 $ 3.95 27,067 $ 3.50  5.70 to 8.81 505,136 7.41 $ 6.93 242,130 $ 6.94  8.94 to 14.01 77,100 3.53 $ 11.18 66,825 $ 11.17  $ 2.80 to $ 14.01 622,636 6.79 $ 7.26 336,022 $ 7.50  Restricted Shares  The Com pany’s restricted stock and restricted stock units under the 2004 Plan generally have been awarded by three methods as follows: 1. Awards that are earned based on an individual’s achievement of performance goals during the initial fiscal year with either a subsequent one - year service vesting period or with a one -third vesting requirement on the first, second and third anniversary of the issuance, provided the individual’s employment has not terminated prior to the vesting date and are freely transferable after vesting; 2. Awards that are earned based on achieving certain revenue and operating income results with a subsequent one -third vesting requirement on the first, second and third anniversary of the issuance provided the individual’s employment has not terminated prior to the vesting date and are freely transferable after vesting; and 3. Awards to non-management members of our Board of Directors with a subsequent one -third vesting requirement on the first, second and third anniversary of the issuance provided the service of the non-management member of our Board of Directors has not terminated prior to the vesting date and are freely transferable after vesting. The grant date fair value associated with the restricted stock is calculated in accordance with ASC 718 “Compensation – Stock Compensation” . Co mpensation expense related to restricted stock awards is based on the closing price of our Common Stock on the grant date authorized by our Board of Directors, multiplied by the number of restricted stock awards expected to be issued and vested and is amortized over the combined performance and service periods. The non-cash stock-based compensation expense recorded for restricted stock awards for the fiscal years ended June 30, 201 7 , 201 6 and 201 5 was $145,000 , $221,000 and $209,000 , respectively. As of June 30, 201 7 , the total remaining unrecognized compensation cost related to restricted stock awards amounted to $31,000 . We expect to recognize this cost over a weighted average vesting period of 0.3 years.  A summary of the status of restricted shares issued at June 30, 201 7 is presented in the table below:    Weighted Average  Nonvested Grant Date  Shares Fair Value  Nonvested at June 30, 2016 41,141 $ 7.82  Granted - -  Vested (28,398) 7.66  Forfeited or expired (967) 9.20  Nonvested at June 30, 2017 11,776 $ 8.08   Board of Directors Fees  Our Board of Directors’ fees are typically payable in cash on September 1, December 1, March 1 , and June 1 of each fiscal year; however, under our 2004 Plan each director can elect to receive our stock in lieu of cash on a calendar year election. Each of our Directors has elected stock for the calendar year 2017. On each payment date, we determine the number of shares of Common Stock each Director has earned by dividing their earned fees by the closing market price of our Common Stock on that date. During fiscal year 2017, we issued 35,290 shares and recorded expense of $363,000 to our Directors for their fees.  Available Shares  At June 30, 201 7 , the 2004 Plan had 607,952 shares available for future grants .

We may be subject to U.S. income taxes and foreign withholding taxes if these earnings are distributed in the future. It is not practicable to estimate the amount of unrecognized deferred tax liability for the undistributed foreign earnings. At June 30, 2017, we had net operating loss carry-forwards for U.S. federal income tax purposes of $28.2 million that expire in the years 2022 through 2036 and tax credit carry-forwards of $5.3 million of which $5.0 million expire in the years 2018 through 2036 . Included in the U.S. federal net operating loss carry-forward is $8.3 million from the exercise of employee stock options, the tax be nefit of which has not recognized. Upon adoption of ASU 2016-09 on July 1, 2017, we expect to record a deferred tax asset for the tax effect of these net operating losses along with a corresponding increase in a valuation allowance .  Our deferred tax assets are substantially represented by the tax benefit of U.S. net operating losses “(NOL’s”), tax credit carry-forwards and the tax benefit of future deductions represented by timing differences for deferred revenue, inventory obsolescence, allowances for bad debts, warranty expenses and unrealized losses on in vestments. We assess the realizability of the NOL’s and tax credit carry-forwards based on a number of factors including our net operating history, the volatility of our earnings, our accuracy of forecasted earnings for future periods and the general business climate at the end of fiscal 201 7 . As of June 30, 201 6, we had been in a three -year cumulative loss position in the U.S. , therefore, at this time, we determined that it was not more likely than not that any of our U.S. deferred tax assets would be realized as benefits in the future. Accordingly, we established a full valuation allowance against our U.S. net deferred tax assets as of June 30, 2016 and this valuation allowance remains at June 30, 2017 . Additionally during fiscal year 2016 and 2017 , we established full valuation allow ances against our Germany, Japan, Singapore and Brazil net deferred tax assets for similar reasons . The net change in the total valuation allowance for the fiscal years ended June 30, 2017, 2016 and 2015 was ($354,000) , $16,349,000 , and $0 , respectively. We also have a deferred tax liability related to the basis difference in the Coord3 intangible assets acquired.  On June 30, 2017 and 2016, we had $120,000 and $251,000 of unrecognized tax benefits that would affect the effective tax rate if recognized. Our policy is to classify interest and penalties related to unrecognized tax benefits as interest expense and income tax expense, respectively. As of June 30, 2017 , there was no accrued interest or penalties related to uncertain tax positions recorded on our Consolidated Balance Sheets or Consolidated Statements of Operations. For U.S. federal income tax purposes, the tax years 2014 through 2017 remain open to examination by government tax authorities. For German income tax purposes, tax years 2013 through 2017 remain open to examination by government tax authorities. At June 30, 2017, our China location has no tax years open to examination.  The aggregate changes in the balance of unrecognized tax benefits were as follows (in thousands):     2017  Balance, at June 30, 2016 $ 251  Increases for tax positions related to the current year -  Decreases for tax positions related to the prior year (131)  Balance, at June 30, 2017 $ 120

Segment And Geographic Information [Abstract]
Segment And Geographic Information	17 . Segment and Geographic Information  We manage our business under three operating segments: Americas, Europe and Asia. All of our operating segments rely on our core technologies and sell the same products primarily in the global automotive industry. The segments also possess similar economic characteristics, resulting in similar long-term expected financial performance. In addition, we sell to the same customers in all of our operating segments. Accordingly, our operating segments are aggregated into one reportable segment.  We account for geographic sales based on the country from which the sale is invoiced rather than the country to which the product is shipped.

Summary Of Significant Accounting Policies [Abstract]
Operations	Operations  Perceptron, Inc. (“Perceptron” “we”, “us” or “our”) develops, produces and sells a comprehensive range of automated industrial metrology products and solutio ns to manufacturer s for dimensional gauging, dimensional inspection and 3D scanning products. Our products provide solutions for manufacturing process control as well as sensor and software technologies for non-contact measurement, scanning and inspecti on applications. We also offer v alue added s ervices such as training and customer support services.
Basis Of Presentation And Principles Of Consolidation	Basis of Presentation and Principles of Consolidation  The C onsolidated F inancial S tatements and accompanying notes are prepared in accordance with generally accepted accounting principles in the United State s of America (“U.S. GAAP”). Our Consolidated Financial S tatements include the accounts of Perceptron and our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.  These consolidated financial statements include the results of our acquisitions of Next Metrology Software s.r.o. (“NMS”), which was consummated on January 29, 2015, and Coord3 s.r.l. (“Coord3”), which was consummated on February 27, 2015, from their acquisition dates. See Note 2, “Acquisitions”, below.  Management is required to make certain estimates and assumptions under U.S. GAAP during the preparation of these Consolidated Financial Statements. These estimates and assumptions may affect the reported amounts of assets and liabilities as well as the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition  Revenue related to products and services is recognized upon shipment when title and risk of loss has passed to the customer or upon completion of the service, there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the related receivable is reasonably assured and customer acceptance criteria, if any, have been successfully demonstrated.  We also have multiple element arrangements in our Measurement Solutions product line which may include elements such as, equipment, installation, labor support and/or training. Each element has value on a stand-alone basis and the delivered elements do not include general rights of return. Accordingly, each element is considered a separate unit of accounting. When available, we allocate arrangement consideration to each element in a multiple element arrangement based upon vendor specific objective evidence (“VSOE”) of fair value of the respective elements. When VSOE cannot be established, we attempt to establish the selling price of each element based on relevant third-party evidence. Our products contain a significant level of proprietary technology, c ustomization or differentiation; therefore, comparable pricing of products with similar functionality cannot be obtained. In these cases, we utilize our best estimate of selling price (“BESP”). We determine the BESP for a product or service by considering multiple factors including, but not limited to, pricing practices, internal costs, geographies and gross margin.  For multiple element arrangements, we defer from revenue recognition the greater of the relative fair value of any undelivered elements of the contract or the portion of the sales price of the contract that is not payable until the undelivered elements are completed. As part of this evaluation, we limit the amount of revenue recognized for delivered elements to the amount that is not contingent on the future delivery of products or services, including a consideration of payment terms that delay payment until those future deliveries are completed.  Some multiple element arrangements contain installment payment terms with a final payment (“final buy-off”) due upon the completion of all elements in the arrangement or when the customer’s final acceptance is received. We recognize revenue for each completed element of a contract when it is both earned and realizable. A provision for final customer acceptance generally does not preclude revenue recognition for the delivered equipment element because we rigorously test equipment prior to shipment to ensure it will function in our customer’s environment. The final acceptance amount is assigned to specific element(s) identified in the contract, or if not specified in the contract, to the last element or elements to be delivered that represent an amount at least equal to the final payment amount.  Our Measurement Solutions are designed and configured to meet each customer’s specific requirements. Timing for the delivery of each element in the arrangement is primarily determined by the customer’s requirements and the number of elements ordered. Delivery of all of the multiple elements in an order will typically occur over a three to 15 -month period after the order is received. We do not have price protection agreements or requirements to buy back inventory. Our history demonstrates that sales returns have been insignificant.
Research And Development	Research and Development  In fiscal year 2015 and the first half of fiscal 2016, in connection with our NMS acquisition, costs incurred after technological feasibility for certain new products were capitalized. In the third quarter of fiscal 2016, we recorded an impairment charge of $694,000 for one of these products. The remaining capitalized costs will continue to be amortized to cost of goods sold over the estimated lives of these products. All other research and development costs, including future software development costs, are expensed as incurred.
Foreign Currency	Foreign Currency  The financial statements of our wholly-owned foreign subsidiaries are translated in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 830, “Foreign Currency Translation Matters”. The functional currency of most of our non-U.S. subsidiaries is the local currency. Under this standard, translation adjustments are accumulated in a separate component of shareholders’ equity until disposal of the subsidiary. Gains and losses on foreign currency transactions are included in our Consolidated Statement of Operations under “Foreign currency income (loss), net”.
Earnings Per Share	Earnings Per Share  Basic earnings per share (“EPS”) is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Other obligations, such as stock options and restricted stock awards, are considered to be potentially dilutive common shares. Diluted EPS assumes the issuance of potential dilutive common shares outstanding during the period and adjusts for any changes in income and the repurchase of common shares that would have occurred from the assumed issuance, unless such effect is anti-dilutive. The calculation of diluted shares also takes into effect the average unrecognized non-cash stock-based compensation expense and additional adjustments for tax benefits related to non-cash stock-based compensation expense. Furthermore, we exclude all outstanding options to purchase common stock from the computation of diluted EPS in periods of net losses because the effect is anti-dilutive.  Options to purchase 119,000 , 194,000 and 181,000 shares of common stock, for the fiscal years ended June 30, 201 7 , 201 6 and 201 5 , were not included in the computation of diluted EPS because the effect would have been anti-dilutive.
Cash And Cash Equivalents	Cash and Cash Equivalents  We consider all highly liquid investments purchased with maturities of three months or less to be cash equivalents. Fair value approximates carrying value because of the short maturity of the cash equivalents. At June 30, 201 7 , we had $3,704,000 i n cash and cash equivalents of which $3,490,000 was held in foreign bank accounts. We maintain our cash in bank deposit accounts, which, at times, may exceed federally insured limits. We have not experienced any losses in such accounts.
Accounts Receivable And Concentration Of Credit Risk	Accounts Receivable and Concentration of Credit Risk  We market and sell our products principally to automotive manufacturers, line builders, system integrators, original equipment manufacturers and value-added resellers. Our accounts receivable are principally from a small number of large customers. We perform ongoing credit evaluations of our customers. Accounts receivable are generally due within 30 to 60 days and are stated at amounts due from customers, net of an allowance for doubtful accounts. Accounts receivable outstanding longer than the contractual payment terms are considered past due. We determine our allowance for doubtful accounts by considering a number of factors, including the length of time trade accounts receivable are past due, our previous loss history, our customer’s current ability to pay their outstanding balance due to us and the conditio n of the general economy and that industry as a whole. We write-off accounts receivable when they become uncollectible; payments subsequently received on such receivables are included in the allowance for doubtful accounts.
Short-Term And Long-Term Investments	Short-Term and Long-Term Investments  We account for our investments in accordance with ASC 320, “Investments – Debt and Equity Securities ”. Investments with a term to maturity between three months to one year are considered short-term investments and are classified as available-for-sale investments. Investments with a term to maturity beyond one year may be classified as available for sale if we reasonably expect the investment to be realized in cash or sold or consumed during the normal operating cycle of the business. Investments are classified as held-to-maturity if the term to maturity is greater than one year and we have the intent and ability to hold such investments to maturity. All investments are initially recognized at fair value. Subsequent measurement for available-for-sale investments is recorded at fair value. Unrealized gains and losses on available-for-sale investments are recorded in other comprehensive income. Held-to-maturity investments are subsequently measured at amortized cost. At each balance sheet date, we evaluate all investments for possible other-than-temporary impairment which involves significant judgment. In making this judgment, we review factors such as the length of time and extent to which fair value has been below the cost basis, the anticipated recovery period, the financial condition of the issuer, the credit rating of the instrument and our ability and intent to hold the investment for a period of time which may be sufficient for recovery of the cost basis. Any losses determined to be other-than-temporary are charged as an impairment loss and recorded in earnings. If market, industry, and/or investee conditions deteriorate, future impairments may be incurred.
Inventory	Inventory  Inventory is stated at the lower of cost or market. The cost of inventory is determined by the first-in, first-out (“FIFO”) method. We provide a reserve for obsolescence to recognize inventory impairment for the effects of engineering change orders, age and use of inventory that affect the value of the inventory. The reserve for obsolescence creates a new cost basis for the impaired inventory. When inventory that has previously been impaired is sold or disposed of, the related obsolescence reserve is reduced resulting in the reduced cost basis being reflected in cost of goods sold. A detailed review of the inventory is performed annually with quarterly updates for known changes that have occurred since the annual review.
Financial Instruments	Financial Instruments  The carrying amounts of our financial instruments, which include cash and cash equivalents, short-term investments, accounts receivable, accounts payable and amounts due to banks or other lenders, approximate their fair values at June 30, 201 7 and 201 6 . See “Short-Term and Long-Term Investments” for a discussion of our investments. Fair values have been determined through information obtained from market sources and management estimates.  We follow the provisions of ASC 820, “Fair Value Measurements and Disclosures” for all financial assets and liabilities as well as nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. ASC 820 defines fair value, establishes a framework for measuring fair value and required specific disclosures about fair value measurements. Our financial instruments include investments classified as available for sale, mutual funds, fixed deposits and certificate of deposits at June 30, 201 7 .  ASC 820 establishes a hierarchy of valuation techniques based upon whether the inputs to those valuation techniques reflect assumptions other market participants would use based upon market data obtained from independent sources (observable inputs), or reflect our assumptions of market participant valuation (unobservable inputs). These two types of inputs create the following fair value hierarchy:  · Level 1 – Quoted prices in active markets that are unadjusted and accessible at the measurement date for identical, unrestricted assets or liabilities.  · Level 2 – Quoted prices for identical assets and liabilities in markets that are not active, quoted prices for similar assets and liabilities in active markets or financial instruments for which significant inputs are observable, either directly or indirectly.  · Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable and reflect management’s estimates and assumptions.  ASC 820 requires the use of observable market data if such data is available without undue cost and effort.
Property And Equipment	Property and Equipment  Property and equipment are recorded at historical cost. Depreciation related to machinery and equipment and furniture and fixtures is primarily computed on a straight-line basis over estimated useful lives ranging from 3 to 15 years. Depreciation on buildings is computed on a straight-line basis over 40 years. Depreciation on building improvements is computed on a straight-line basis over estimated useful lives ranging from 10 to 15 years. Our depreciation expense for the years ended June 30, 201 7 , 201 6 , and 201 5 was $1,121,000 , $1,016,000 , and $770,000 , respectively.
Goodwill	Goodwill  Goodwill represents the excess purchase price over the fair value of the net amounts assigned to assets acquired and liabilities assumed in connection with our acquisitions. Under ASC Topic 805 “ Business Combinations” , we are required to test goodwill for impairment annually or more frequently, whenever events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit with goodwill below its carrying amount. Application of the goodwill impairment test requires judgment, including assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units and determination of the fair value of each reporting unit.  The qualitative events or circumstances that could affect the fair value of a reporting unit could include economic conditions; industry and market considerations, including competition; increases in raw materials, labor, or other costs; overall financial performance such as negative or declining cash flows; relevant entity-specific events such as changes in management, key personnel, strategy, or customers; sale or disposition of a significant portion of a reporting unit and regulatory or political developments. Companies have the option under ASC Topic 350 “Intangibles – Goodwill and Other” to evaluate goodwill based upon these qualitative factors, and if it is more likely than not that the fair value of the reporting unit is greater than its carrying amount, then no further goodwill impairment tests are necessary. If the qualitative review indicates it is more likely than not that the fair value of the reporting unit is less than its carrying amount, or if we choose not to perform a qualitative assessment, a two-step quantitative impairment test is performed to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized, if any. During the fourth quarter of fiscal 2017, we completed our goodwill impairment testing by performing a quantitative assessment.  Step 1 is to identify potential impairment by comparing fair value of a reporting unit with its carrying value, including goodwill. If the fair value is lower than the carrying value, this is an indication of goodwill impairment and Step 2 must be performed. Under Step 2, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. This analysis requires significant judgment in developing assumptions, such as estimating future cash flows, which is dependent on internal forecasts, estimating the long-term rate of growth for our business, estimating the useful life over which cash flows will occur and calculating our weighted average cost of capital. The estimates used to calculate the fair value of a reporting unit change from year to year based on operating results, market conditions, foreign currency fluctuations and other factors. Changes in these estimates and assumptions could materially affect the determination of fair value and could result in goodwill impairment for a reporting unit, negatively impacting our results of operations for the period and financial position.  During the fourth quarter of fiscal year 201 7 , we completed Step 1 of our goodwill impairment testing. Based on the results of this test, the fair value of our tested reporting unit exceeded our carrying value by 26% . As a result, no impairment loss was recognized . Goodwill is recorded on the local books of Coord3 and NMS and foreign currency effects will impact the balance of goodwill in future periods. As of June 30, 201 7 , and 2016, our goodwill balance is $7,793,000 and $7,500,000 , respectively, with the increase due to the differences in foreign currency rates at June 30, 201 6 compared to June 30, 201 7 .
Intangibles	 Intangible s  We acquired intangible assets in addition to goodwill in connection with the acquisitions of Coord3 and NMS. These assets are susceptible to shortened estimated useful lives and changes in fair value due to changes in their use, market or economic changes, or other events or circumstances. We evaluate the potential impairment of these intangible assets whenever events or circumstances indicate their carrying value may not be recoverable. Factors that could trigger an impairment review include historical or projected results that are less than the assumptions used in the original valuation of an intangible asset, a change in our business strategy or our use of an intangible asset or negative economic or industry trends.  If an event or circumstance indicates that the carrying value of an intangible asset may not be recoverable, we assess the recoverability of the asset by comparing the carrying value of the asset to the sum of the undiscounted future cash flows that the asset is expected to generate over its remaining economic life. If the carrying value exceeds the sum of the undiscounted future cash flows, we compare the fair value of the intangible asset to the carrying value and record an impairment loss for the difference. We generally estimate the fair value of our intangible assets using the income approach based upon a discounted cash flow model. The income approach requires the use of many assumptions and estimates including future revenues and expenses, discount factors, income tax rates, the identification of groups of assets wit h highly independent cash flows and assets’ economic lives. Volatility in the global economy makes these assumptions and estimates more judgmental. Actual future operating results and the remaining economic lives of our other intangible assets could differ from those used in assessing the recoverability of these assets and could result in an impairment of other intangible assets in future periods.  The amortization periods for customer/distributor relationships, trade name and software are five years, ten years and five years, respectively.  
Deferred Income Taxes	Deferred Income Taxes  Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and the effects of operating losses and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for deferred tax assets if it is more likely than not that these items will either expire before we are able to realize their benefit or future deductibility is uncertain (see Note 1 6 “Income Taxes” for further discussion).
Warranty	Warranty  Our In-Line and Near-Line Measurement Solutions generally carry a one to three -year warranty for parts and a one -year warranty for labor and travel related to warranty. Product sales to the forest products industry carry a three -year warranty for TriCam ® sensors. Sales of ScanWorks ® have a one -year warranty for parts. Sales of WheelWorks ® products have a two -year warranty for parts. We provide a reserve for warranty based on our experience and knowledge. Our Off-Line Measurement Solutions generally carry a twelve -month warranty after the machine passes the acceptance test or a fifteen -month warranty from the date of shipment, whichever date comes first, on parts only.  Factors affecting our warranty reserve include the number of units sold or in-service as well as historical and anticipated rates of claims and cost per claim. We periodically assess the adequacy of our warranty reserve based on changes in these factors. If a special circumstance arises which requires a higher level of warranty, we make a special warranty provision commensurate with the facts.
Self-Insurance	Self–Insurance  In the U.S. we were self-insured for health and vision costs up to a certain stop-loss level per claim and on an aggregate basis of a percentage of estimated annual costs until December 31, 2016 . Starting January 1, 2017, we went to a fully-insured model for health and vision coverages we offer our U.S employees. We are currently self-insured for any short-term disability claims we may have outstanding.
New Accounting Pronouncements	New Accounting Pronouncements  In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. In March 2016, the FASB issued the final guidance to clarify the principal versus agent guidance (i.e., whether an entity should report revenue gross or net). In April 2016, the FASB issued final guidance to clarify identifying performance obligation and the licensing implementation guidance. In May 2016, FASB updated the guidance in ASU No. 2014-09, which updated implementation of certain narrow topics within ASU 2014-09. Finally, in December 2016, the FASB issued several technical corrections and improvements, which clarify the previously issued standards and corrected unintended application of previous guidance. These standards (collectively “ASC 606”) will be effective for annual periods beginning after December 15, 2017 (as amended in August 2015, by ASU 2015-14, Deferral of the Effective Date), and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the applications of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). We have commenced a detailed analysis of our contracts under ASC 606 and expect to decide which transition method we will utilize to adopt ASC 606 by the end of our second quarter of fiscal 2018 . Based on our preliminary analyses, we expect changes in timing of revenue recognition related to several of our performance obligations; in general, we believe we will be recognizing revenue more quickly than under current revenue recognition guidance. Furthermore, we believe that our Consolidated Balance Sheet will be impacted as we identify Contract Assets and Contract Liabilities. We do not expect a change to the level of disaggregation for our disclosures, although we do expect to provide additional detail about the timing of revenue recognition for several of our performance obligations and about our Contract Assets and Contract Liabilities.  In July 2015, the FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory (ASU 2015-11), which changes the measurement of inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. There were also amendments to the guidance to more clearly articulate the requirements for the measurement and disclosure of inventory. ASU 2015-11 is effective for Perceptron on July 1, 2017 and is not expected to have a significant impact on our consolidated financial statements or disclosures.  In November 2015, the FASB issued Accounting Standards Update No. 2015-17, Balance Sheet Classification of Deferred Taxes (ASU 2015-17), which requires all deferred tax assets and liabilities, included related valuation allowances, be classified as non-current on our consolidated balance sheets. ASU 2015-17 is effective b eginning July 1, 2017 and is expected to result in reclassification on our balance sheet.  In January 2016, the FASB issued Accounting Standards Update No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01), which amends certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASC 2016-01 is effective beginning for Perceptron on July 1, 2018 and is not expected to have a significant impact on our consolidated financial statements or disclosures.  In February 2016, the FASB issued Accounting Standards Update No. 2016-02 Leases (ASU 2016-2), which establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. A modified retrospective transition approach is required for lessees with capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We are currently evaluating the impact of the adoption of ASU 2016-02 on our consolidated financial statements.  In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09), which changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU 2016-09 is effective for fiscal years and interim periods beginning after December 15, 2016, with early adoption permitted . Due to the fact our US Federal Deferred Taxes have a full Valuation Allowance, ASU 2016-09 is not expected to have a significant impact on our consolidated financial statements.  In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments – Credit Losses (Topic 326) (ASU 2016-13), which requires the measurement of all expected credit losses for financial assets held at the reporting date to be based on historical experience, current conditions as well as reasonable and supportable forecasts. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019 including interim periods within those fiscal years, with early adoption permitted. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements.  In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15), which 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 Perceptron beginning on July 1, 2018 and requires us to utilize a retrospective adoption unless it is impracticable for us to apply, in which case, we would be required to apply the amendment prospectively as of the earliest date practicable. We are currently evaluating the impact of the adoption of ASU 2016-15 on our consolidated statement of cash flows.  In October 2016, the FASB issued Accounting Standards Update No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (ASU 2016-16), which requires that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. ASU 2016-16 is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance. We are currently evaluating the impact of the adoption of ASU 2016-16 on our consolidated financial statements.  In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18), which requires a company to present their Statement of Cash Flows including amounts generally described as restricted cash or restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted. We are currently evaluating the impact of the adoption of ASU 2016-18 on our consolidated statement of cash flows.  In January 2017, the FASB issued Accounting Standards Update No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (ASU 2017-01), which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 is effective for Perceptron on July 1, 2018 and is not expected to have a significant impact on our consolidated financial statements or disclosures.  In January 2017, the FASB issued Accounting Standards Update No. 2017-04, Intangibles—Goodwill and Other (Topic 350) (ASU 2017-04), which simplifies the Test for Goodwill Impairment. No. 2017-04 is effective for annual reporting periods beginning after December 15, 2019 with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the impact of the adoption of ASU 2017-04 on our consolidated financial statements and disclosures.  In February 2017, the FASB issued Accounting Standards Update No. 2017-05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (ASU 2017-05), which clarifies the scope of Subtopic 610-20 and adds guidance for partial sales of nonfinancial assets. Subtopic 610-20, which was issued in May 2014 as a part of Accounting Standards Update No. 2014-09, provides guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. ASU 2017-05 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period with early application permitted only as of annual reporting periods beginning after December 15, 2016. We do not expect ASU 2017-05 to have a significant impact on our consolidated financial statements or disclosures.  In May 2017, the FASB issued Accounting Standards Update No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting (ASU 2017-09), which provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation—Stock Compensation, to a change to the terms or conditions of a share-based payment award. ASU 2017-09 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. We do not expect ASU 2017-09 to have a significant impact on our consolidated financial statements or disclosures.
