Accounting Policies [Abstract]
Significant Accounting Policies	Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Reclassifications. The classification of certain prior-year amounts have been adjusted in our Consolidated Financial Statements to conform to current-year classifications. Reclassifications include the line item “Interest expense – debt costs” which is now combined with the “Interest expense, net” line item in our Consolidated Statements of Comprehensive Income. Management estimates. Management makes estimates and assumptions during the preparation of the Company’s Consolidated Financial Statements that affect amounts reported in the Consolidated Financial Statements and accompanying notes. Such estimates and assumptions could change in the future as more information becomes available, which, in turn, could impact the amounts reported and disclosed herein. Cash and cash equivalents consist of cash in the bank and cash equivalents with maturities of 90 days or less when purchased. The Company maintains its cash accounts in various institutions with high credit ratings. The Company’s domestic cash accounts are maintained in one financial institution, and balances may exceed federal insured limits at times. The Company’s foreign cash accounts are not insured. Restricted cash consists of amounts held in restricted accounts as collateral associated with our debt covenants. See Note 18, Loans Payable, to these Consolidated Financial Statements for additional information. Our restricted cash is invested in a money market account. During fiscal year 2018, the Company adopted ASU 2016-18, “Statement of Cash Flows (Topic 320): Restricted Cash” (“ASU 2016-18”), which provides guidance on the presentation of restricted cash and restricted cash equivalents in the statement of cash flows. Cash and cash equivalents and restricted cash presented in the Consolidated Balance Sheet as of June 30, 2018 are combined in the Consolidated Statement of Cash Flows for the year ended June 30, 2018. Allowance for accounts receivable is calculated by taking 100% of the total of invoices that are over 90 days past due from the due date and 10% of the total of invoices that are over 60 days past due from the due date for U.S.- and Latvia-based accounts and 100% of invoices that are over 120 days past due for Chinese-based accounts. Accounts receivable are customer obligations due under normal trade terms. The Company performs continuing credit evaluations of its customers’ financial condition. If the Company’s actual collection experience changes, revisions to its allowance may be required. After all attempts to collect a receivable have failed, the receivable is written off against the allowance. Inventories, which consist principally of raw materials, tooling, work-in-process and finished lenses, collimators and assemblies are stated at the lower of cost or net realizable value, on a first-in, first-out basis. Inventory costs include materials, labor and manufacturing overhead. Acquisition of goods from our vendors has a purchase burden added to cover customs, shipping and handling costs. Fixed costs related to excess manufacturing capacity have been expensed. The Company looks at the following criteria for parts to consider for the inventory allowance: (i) items that have not been sold in two years, (ii) items that have not been purchased in two years, or (iii) items of which we have more than a two-year supply. These items, as identified, are allowed for at 100%, as well as allowing 50% for other items deemed to be slow moving within the last twelve months and allowing 25% for items deemed to have low material usage within the last six months. The parts identified are adjusted for recent order and quote activity to determine the final inventory allowance. Property and equipment are stated at cost and depreciated using the straight-line method over the estimated useful lives of the related assets ranging from one to ten years. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful lives of the related assets using the straight-line method. Construction in process represents the accumulated costs of assets not yet placed in service and primarily relates to manufacturing equipment. Long-lived assets, such as property, plant, and equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to its estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the Consolidated Balance Sheet and reported at the lower of the carrying amount or fair value less costs to sell, and would no longer be depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the Consolidated Balance Sheet. Goodwill and Intangible Assets acquired in a business combination are recognized at fair value using generally accepted valuation methods appropriate for the type of intangible asset and reported separately from goodwill. Purchased intangible assets other than goodwill are amortized over their useful lives unless these lives are determined to be indefinite. Purchased intangible assets are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets, generally two to fifteen years. The Company periodically reassesses the useful lives of its intangible assets when events or circumstances indicate that useful lives have significantly changed from the previous estimate. Definite-lived intangible assets consist primarily of customer relationships, know-how/trade secrets and trademarks. They are generally valued as the present value of estimated cash flows expected to be generated from the asset using a risk-adjusted discount rate. When determining the fair value of our intangible assets, estimates and assumptions about future expected revenue and remaining useful lives are used. Goodwill and intangible assets are tested for impairment on an annual basis and during the period between annual tests if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. The Company will assess the qualitative factors to determine whether it is more likely than not that the fair value of its reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the goodwill impairment analysis. If the Company determines that it is more likely than not that its fair value is less than its carrying amount, then the goodwill impairment test is performed. The first step, identifying a potential impairment, compares the fair value of the reporting unit with its carrying amount. If the carrying amount exceeds its fair value, the second step would need to be performed; otherwise, no further steps are required. The second step, measuring the impairment loss, compares the implied fair value of the goodwill with the carrying amount of the goodwill. Any excess of the goodwill carrying amount over the implied fair value is recognized as an impairment loss, and the carrying value of goodwill is written down to fair value. During fiscal year 2018, the Company adopted ASU 2017-4, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-4”), which amends the goodwill impairment test to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, up to the total amount of goodwill allocated to that reporting unit. The Company did not record any goodwill impairment during the fiscal years ended June 30, 2018 or 2017. Deferred rent relates to certain of the Company’s operating leases containing predetermined fixed increases of the base rental rate during the lease term being recognized as rental expense on a straight-line basis over the lease term, as well as applicable leasehold improvement incentives provided by the landlord. The Company has recorded the difference between the amounts charged to operations and amounts payable under the leases as deferred rent in the accompanying Consolidated Balance Sheets. Income taxes are accounted for under the asset and liability method. Deferred income tax assets and liabilities are computed on the basis of differences between the financial statement and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future based upon enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances have been established to reduce deferred tax assets to the amount expected to be realized. The Company has not recognized a liability for uncertain tax positions. A reconciliation of the beginning and ending amount of unrecognized tax benefits or penalties has not been provided since there has been no unrecognized benefit or penalty. If there were an unrecognized tax benefit or penalty, the Company would recognize interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expenses. The Company files U.S. Federal income tax returns, as well as tax returns in various states and foreign jurisdictions. Open tax years subject to examination by the Internal Revenue Service generally remain open for three years from the filing date. Tax years subject to examination by the state jurisdictions generally remain open for up to four years from the filing date. In Latvia, tax years subject to examination remain open for up to five years from the filing date, and in China, tax years subject to examination remain open for up to ten years from the filing date. Our cash, cash equivalents and restricted cash totaled $6.5 million at June 30, 2018. Of this amount, approximately 50% was held by our foreign subsidiaries in China and Latvia. These foreign funds were generated in China and Latvia as a result of foreign earnings. With respect to the funds generated by our foreign subsidiaries in China, the retained earnings in China must equal at least 150% of the registered capital before any funds can be repatriated. As of June 30, 2018, we have retained earnings in China of approximately $1.9 million and we need to have $11.3 million before repatriation will be allowed. Accumulated earnings from the Company’s non-U.S. subsidiaries were subject to inclusion in the Company’s current period U.S. and state income tax returns as a result of the impact of the U.S. tax law changes. However, no income tax was due on the inclusion of these earnings due to utilization of net operating losses. See Note 9, Income Taxes, to these Consolidated Financial Statements for additional information. The Company intends to permanently invest earnings generated from its foreign Chinese operations, and, therefore, has not previously provided for future Chinese withholding taxes on such related earnings. However, if, in the future, the Company changes such intention, the Company would provide for and pay additional foreign taxes, if any, at that time. Revenue is recognized from product sales when products are shipped to the customer, provided that the Company has received a valid purchase order, the price is fixed, title has transferred, collection of the associated receivable is reasonably assured, and there are no remaining significant obligations. Product development agreements are generally short term in nature with revenue recognized upon shipment to the customer for products, reports or designs. Invoiced amounts for sales for value-added taxes (“VAT”) are posted to the balance sheet and are not included in revenue. VAT is computed on the gross sales price on all sales of the Company’s products sold in the People’s Republic of China and Latvia. The VAT rates range up to 21%, depending on the type of products sold. The VAT may be offset by VAT paid by the Company on raw materials and other materials included in the cost of producing or acquiring its finished products. The Company recorded a VAT receivable net of payables in the accompanying Consolidated Financial Statements. New product development costs are expensed as incurred. Stock-based compensation is measured at grant date, based on the fair value of the award, and is recognized as an expense over the employee’s requisite service period. We estimate the fair value of each restricted stock unit or stock option as of the date of grant using the Black-Scholes-Merton pricing model. Most awards granted under our Amended and Restated Omnibus Incentive Plan, as amended (the “Omnibus Plan”), vest ratably over two to four years and generally have four to ten-year contract lives. The volatility rate is based on historical trends in common stock closing prices and the expected term was determined based primarily on historical experience of previously outstanding awards. The interest rate used is the U.S. Treasury interest rate for constant maturities. The likelihood of meeting targets for option grants that are performance based are evaluated each quarter. If it is determined that meeting the targets is probable, then the compensation expense will be amortized over the remaining vesting period. Fair value of financial instruments. The Company accounts for financial instruments in accordance with the Financial Accounting Standards Board’s Accounting Standards Codification Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”), which provides a framework for measuring fair value and expands required disclosure about fair value measurements of assets and liabilities. ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1 - Quoted prices in active markets for identical assets or liabilities. Level 2 - Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable. Level 3 - Unobservable inputs that are supported by little or no market activity, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing. Fair value estimates discussed herein are based upon certain market assumptions and pertinent information available to management. The respective carrying value of certain on-balance-sheet financial instruments approximated their fair values. These financial instruments include receivables, accounts payable and accrued liabilities. Fair values were assumed to approximate carrying values for these financial instruments since they are short term in nature and their carrying amounts approximate fair values or they are receivable or payable on demand. The fair value of the Company’s capital lease obligations and acquisition term loan payable to Avidbank Corporate Finance, a division of Avidbank (“Avidbank”) approximates their carrying values based upon current rates available to us. Loans payable as of June 30, 2017 also included a note payable to the sellers of ISP, in the aggregate principal amount of $6 million (the “Sellers Note”). The carrying value of the Sellers Note included a fair value premium based on a risk-adjusted discount rate, a Level 2 fair value measurement. On January 16, 2018, the Sellers Note was satisfied in full and, therefore, is not included in loans payable as of June 30, 2018. See Note 18, Loans Payable, to these Consolidated Financial Statements for additional information. The Company valued its warrant liabilities based on open-form option pricing models which, based on the relevant inputs, render the fair value measurement at Level 3. The Company based its estimates of fair value for warrant liabilities on the amount it would pay a third-party market participant to transfer the liability and incorporates inputs such as equity prices, historical and implied volatilities, dividend rates and prices of convertible securities issued by comparable companies maximizing the use of observable inputs when available. See Note 17, Derivative Financial Instruments (Warrant Liability), to these Consolidated Financial Statements for additional information. The Company does not have any other financial or non-financial assets or liabilities that would be characterized as Level 1, Level 2 or Level 3 instruments. Debt issuance costs are recorded as a reduction to the carrying value of the related notes payable, by the same amount, and are amortized ratably over the term of the related note. Derivative financial instruments. The Company accounts for derivative instruments in accordance with Financial Accounting Standards Board’s Accounting Standards Codification Topic 815, “Derivatives and Hedging” (“ASC 815”), which requires additional disclosures about the Company’s objectives and strategies for using derivative instruments, how the derivative instruments and related hedged items are accounted for, and how the derivative instruments and related hedging items affect the financial statements. The Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risk. Terms of convertible debt instruments are reviewed to determine whether or not they contain embedded derivative instruments that are required under ASC 815 to be accounted for separately from the host contract, and recorded on the balance sheet at fair value. The fair value of derivative liabilities, if any, is required to be revalued at each reporting date, with corresponding changes in fair value recorded in current period operating results. The Company issued warrants in connection with our June 2012 private placement (the “June 2012 Warrants”). The fair value of the June 2012 Warrants was estimated using the Lattice option-pricing model. Freestanding warrants issued by the Company in connection with the issuance or sale of debt and equity instruments are considered to be derivative instruments. Pursuant to ASC 815, an evaluation of specifically identified conditions is made to determine whether the fair value of warrants issued is required to be classified as equity or as a derivative liability. Comprehensive income is defined as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. It includes all changes in equity during a period, except those resulting from investments by owners and distributions to owners. Comprehensive income has two components, net income, and other comprehensive income, and is included on the Consolidated Statements of Comprehensive Income. Our other comprehensive income consists of foreign currency translation adjustments made for financial reporting purposes. Business segments. As the Company only operates in principally one business segment, no additional reporting is required. Recent accounting pronouncements. There are new accounting pronouncements issued by the Financial Accounting Standards Board (“FASB”) that are not yet effective for the Company for the year ended June 30, 2018. Revenue from Contracts with Customers – In May 2014, FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (Topic 606) (“ASU 2014-09”), which supersedes the revenue recognition requirements in ASC Topic 605, “Revenue Recognition,” and most industry-specific guidance. ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 must be applied using one of two retrospective methods and were originally set to be effective for annual and interim periods beginning after December 15, 2016. On July 9, 2015, the FASB modified ASU 2014-09 to be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. As modified, the FASB permits the early adoption of the new revenue standard, but not before the annual periods beginning after December 15, 2017. A public organization would apply the new revenue standard to all interim reporting periods within the year of adoption. The Company will adopt this standard in the first quarter of its fiscal year ended June 30, 2019, using the modified retrospective method. We have substantially completed our analysis, and the adoption of this guidance will not have a material impact on our Consolidated Financial Statements and our internal controls over financial reporting. Leases – In February 2016, the FASB issued ASU No. 2016-02, “Leases” (“ASU 2016-02”). This guidance requires an entity to recognize lease liabilities and a right-of-use asset for all leases on the balance sheet and to disclose key information about the entity’s leasing arrangements. ASU 2016-02 must be adopted using a modified retrospective approach for all leases existing at, or entered into after the date of initial adoption, with an option to elect to use certain transition relief. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, with earlier adoption permitted. Our current operating lease portfolio is primarily comprised of real estate leases. Upon adoption of this standard, the Company expects its Consolidated Balance Sheet to include a right-of-use asset and liability related to substantially all of its operating lease arrangements. ASU 2016-02 will be effective for the Company in the first quarter of its fiscal year ending June 30, 2020. Income Taxes – In October 2016, the FASB issued ASU 2016-16, “Income Taxes” (Topic 740) (“ASU 2016-16”). ASU 2016-16 requires an entity to 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 fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual reporting period for which financial statements have not been issued or made available for issuance. ASU 2016-16 is effective for the Company in the first quarter of its fiscal year ending June 30, 2019. The Company does not expect this accounting standard to have a significant impact on its financial results when adopted. Compensation – Stock Compensation – In May 2017, the FASB issued ASU 2017-09, “Compensation - Stock Compensation” (Topic 718): Scope of Modification Accounting (“ASU 2017-09”). The new guidance clarifies when a change to the terms or conditions of a share-based payment award must be accounted for as a modification. ASU 2017-09 is effective for fiscal years, and interim periods within those annual periods, beginning after December 15, 2017, with early adoption permitted. ASU 2017-09 is effective for the Company in the first quarter of its fiscal year ending June 30, 2019. The Company does not expect this accounting standard to have a significant impact on its financial results when adopted. Comprehensive Income - In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”). ASU 2018-02 allows entities to elect to reclassify the income tax effects of the Tax Act on items within accumulated other comprehensive income to retained earnings and requires additional related disclosures. ASU 2018-02 is effective for the Company in the first quarter of its fiscal year ending June 30, 2020. The Company is currently evaluating the impact that ASU 2018-02 will have on its Consolidated Financial Statements. No other new accounting pronouncement recently issued or newly effective had or is expected to have a material impact on the Consolidated Financial Statements.

Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Reclassifications. The classification of certain prior-year amounts have been adjusted in our Consolidated Financial Statements to conform to current-year classifications. Reclassifications include the line item “Interest expense – debt costs” which is now combined with the “Interest expense, net” line item in our Consolidated Statements of Comprehensive Income.

Management estimates. Management makes estimates and assumptions during the preparation of the Company’s Consolidated Financial Statements that affect amounts reported in the Consolidated Financial Statements and accompanying notes. Such estimates and assumptions could change in the future as more information becomes available, which, in turn, could impact the amounts reported and disclosed herein.

Cash and cash equivalents consist of cash in the bank and cash equivalents with maturities of 90 days or less when purchased. The Company maintains its cash accounts in various institutions with high credit ratings. The Company’s domestic cash accounts are maintained in one financial institution, and balances may exceed federal insured limits at times. The Company’s foreign cash accounts are not insured.

Restricted cash consists of amounts held in restricted accounts as collateral associated with our debt covenants. See Note 18, Loans Payable, to these Consolidated Financial Statements for additional information. Our restricted cash is invested in a money market account. During fiscal year 2018, the Company adopted ASU 2016-18, “Statement of Cash Flows (Topic 320): Restricted Cash” (“ASU 2016-18”), which provides guidance on the presentation of restricted cash and restricted cash equivalents in the statement of cash flows. Cash and cash equivalents and restricted cash presented in the Consolidated Balance Sheet as of June 30, 2018 are combined in the Consolidated Statement of Cash Flows for the year ended June 30, 2018.

Allowance for accounts receivable is calculated by taking 100% of the total of invoices that are over 90 days past due from the due date and 10% of the total of invoices that are over 60 days past due from the due date for U.S.- and Latvia-based accounts and 100% of invoices that are over 120 days past due for Chinese-based accounts. Accounts receivable are customer obligations due under normal trade terms. The Company performs continuing credit evaluations of its customers’ financial condition. If the Company’s actual collection experience changes, revisions to its allowance may be required. After all attempts to collect a receivable have failed, the receivable is written off against the allowance.

Inventories, which consist principally of raw materials, tooling, work-in-process and finished lenses, collimators and assemblies are stated at the lower of cost or net realizable value, on a first-in, first-out basis. Inventory costs include materials, labor and manufacturing overhead. Acquisition of goods from our vendors has a purchase burden added to cover customs, shipping and handling costs. Fixed costs related to excess manufacturing capacity have been expensed.

Leasehold improvements are amortized over the shorter of the lease term or the estimated useful lives of the related assets using the straight-line method. Construction in process represents the accumulated costs of assets not yet placed in service and primarily relates to manufacturing equipment.

Long-lived assets, such as property, plant, and equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to its estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the Consolidated Balance Sheet and reported at the lower of the carrying amount or fair value less costs to sell, and would no longer be depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the Consolidated Balance Sheet.

Goodwill and Intangible Assets acquired in a business combination are recognized at fair value using generally accepted valuation methods appropriate for the type of intangible asset and reported separately from goodwill. Purchased intangible assets other than goodwill are amortized over their useful lives unless these lives are determined to be indefinite. Purchased intangible assets are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets, generally two to fifteen years.

Definite-lived intangible assets consist primarily of customer relationships, know-how/trade secrets and trademarks. They are generally valued as the present value of estimated cash flows expected to be generated from the asset using a risk-adjusted discount rate. When determining the fair value of our intangible assets, estimates and assumptions about future expected revenue and remaining useful lives are used. Goodwill and intangible assets are tested for impairment on an annual basis and during the period between annual tests if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable.

The Company will assess the qualitative factors to determine whether it is more likely than not that the fair value of its reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the goodwill impairment analysis.

The Company did not record any goodwill impairment during the fiscal years ended June 30, 2018 or 2017.

Deferred rent relates to certain of the Company’s operating leases containing predetermined fixed increases of the base rental rate during the lease term being recognized as rental expense on a straight-line basis over the lease term, as well as applicable leasehold improvement incentives provided by the landlord.

The Company has not recognized a liability for uncertain tax positions. A reconciliation of the beginning and ending amount of unrecognized tax benefits or penalties has not been provided since there has been no unrecognized benefit or penalty. If there were an unrecognized tax benefit or penalty, the Company would recognize interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expenses.

The Company files U.S. Federal income tax returns, as well as tax returns in various states and foreign jurisdictions. Open tax years subject to examination by the Internal Revenue Service generally remain open for three years from the filing date. Tax years subject to examination by the state jurisdictions generally remain open for up to four years from the filing date. In Latvia, tax years subject to examination remain open for up to five years from the filing date, and in China, tax years subject to examination remain open for up to ten years from the filing date.

Our cash, cash equivalents and restricted cash totaled $6.5 million at June 30, 2018. Of this amount, approximately 50% was held by our foreign subsidiaries in China and Latvia. These foreign funds were generated in China and Latvia as a result of foreign earnings. With respect to the funds generated by our foreign subsidiaries in China, the retained earnings in China must equal at least 150% of the registered capital before any funds can be repatriated. As of June 30, 2018, we have retained earnings in China of approximately $1.9 million and we need to have $11.3 million before repatriation will be allowed.

Accumulated earnings from the Company’s non-U.S. subsidiaries were subject to inclusion in the Company’s current period U.S. and state income tax returns as a result of the impact of the U.S. tax law changes. However, no income tax was due on the inclusion of these earnings due to utilization of net operating losses. See Note 9, Income Taxes, to these Consolidated Financial Statements for additional information.

The Company intends to permanently invest earnings generated from its foreign Chinese operations, and, therefore, has not previously provided for future Chinese withholding taxes on such related earnings. However, if, in the future, the Company changes such intention, the Company would provide for and pay additional foreign taxes, if any, at that time.

Fair value of financial instruments. The Company accounts for financial instruments in accordance with the Financial Accounting Standards Board’s Accounting Standards Codification Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”), which provides a framework for measuring fair value and expands required disclosure about fair value measurements of assets and liabilities. ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable.

Level 3 - Unobservable inputs that are supported by little or no market activity, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing.

Fair value estimates discussed herein are based upon certain market assumptions and pertinent information available to management.

The respective carrying value of certain on-balance-sheet financial instruments approximated their fair values. These financial instruments include receivables, accounts payable and accrued liabilities. Fair values were assumed to approximate carrying values for these financial instruments since they are short term in nature and their carrying amounts approximate fair values or they are receivable or payable on demand. The fair value of the Company’s capital lease obligations and acquisition term loan payable to Avidbank Corporate Finance, a division of Avidbank (“Avidbank”) approximates their carrying values based upon current rates available to us. Loans payable as of June 30, 2017 also included a note payable to the sellers of ISP, in the aggregate principal amount of $6 million (the “Sellers Note”). The carrying value of the Sellers Note included a fair value premium based on a risk-adjusted discount rate, a Level 2 fair value measurement. On January 16, 2018, the Sellers Note was satisfied in full and, therefore, is not included in loans payable as of June 30, 2018. See Note 18, Loans Payable, to these Consolidated Financial Statements for additional information.

The Company valued its warrant liabilities based on open-form option pricing models which, based on the relevant inputs, render the fair value measurement at Level 3. The Company based its estimates of fair value for warrant liabilities on the amount it would pay a third-party market participant to transfer the liability and incorporates inputs such as equity prices, historical and implied volatilities, dividend rates and prices of convertible securities issued by comparable companies maximizing the use of observable inputs when available. See Note 17, Derivative Financial Instruments (Warrant Liability), to these Consolidated Financial Statements for additional information.

The Company does not have any other financial or non-financial assets or liabilities that would be characterized as Level 1, Level 2 or Level 3 instruments.

Debt issuance costs are recorded as a reduction to the carrying value of the related notes payable, by the same amount, and are amortized ratably over the term of the related note.

Derivative financial instruments. The Company accounts for derivative instruments in accordance with Financial Accounting Standards Board’s Accounting Standards Codification Topic 815, “Derivatives and Hedging” (“ASC 815”), which requires additional disclosures about the Company’s objectives and strategies for using derivative instruments, how the derivative instruments and related hedged items are accounted for, and how the derivative instruments and related hedging items affect the financial statements.

The Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risk. Terms of convertible debt instruments are reviewed to determine whether or not they contain embedded derivative instruments that are required under ASC 815 to be accounted for separately from the host contract, and recorded on the balance sheet at fair value. The fair value of derivative liabilities, if any, is required to be revalued at each reporting date, with corresponding changes in fair value recorded in current period operating results. The Company issued warrants in connection with our June 2012 private placement (the “June 2012 Warrants”). The fair value of the June 2012 Warrants was estimated using the Lattice option-pricing model.

Freestanding warrants issued by the Company in connection with the issuance or sale of debt and equity instruments are considered to be derivative instruments. Pursuant to ASC 815, an evaluation of specifically identified conditions is made to determine whether the fair value of warrants issued is required to be classified as equity or as a derivative liability.

Comprehensive income is defined as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. It includes all changes in equity during a period, except those resulting from investments by owners and distributions to owners. Comprehensive income has two components, net income, and other comprehensive income, and is included on the Consolidated Statements of Comprehensive Income. Our other comprehensive income consists of foreign currency translation adjustments made for financial reporting purposes.

Business segments. As the Company only operates in principally one business segment, no additional reporting is required.

Recent accounting pronouncements. There are new accounting pronouncements issued by the Financial Accounting Standards Board (“FASB”) that are not yet effective for the Company for the year ended June 30, 2018.

Revenue from Contracts with Customers – In May 2014, FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (Topic 606) (“ASU 2014-09”), which supersedes the revenue recognition requirements in ASC Topic 605, “Revenue Recognition,” and most industry-specific guidance. ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 must be applied using one of two retrospective methods and were originally set to be effective for annual and interim periods beginning after December 15, 2016. On July 9, 2015, the FASB modified ASU 2014-09 to be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. As modified, the FASB permits the early adoption of the new revenue standard, but not before the annual periods beginning after December 15, 2017. A public organization would apply the new revenue standard to all interim reporting periods within the year of adoption. The Company will adopt this standard in the first quarter of its fiscal year ended June 30, 2019, using the modified retrospective method. We have substantially completed our analysis, and the adoption of this guidance will not have a material impact on our Consolidated Financial Statements and our internal controls over financial reporting.

Leases – In February 2016, the FASB issued ASU No. 2016-02, “Leases” (“ASU 2016-02”). This guidance requires an entity to recognize lease liabilities and a right-of-use asset for all leases on the balance sheet and to disclose key information about the entity’s leasing arrangements. ASU 2016-02 must be adopted using a modified retrospective approach for all leases existing at, or entered into after the date of initial adoption, with an option to elect to use certain transition relief. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, with earlier adoption permitted. Our current operating lease portfolio is primarily comprised of real estate leases. Upon adoption of this standard, the Company expects its Consolidated Balance Sheet to include a right-of-use asset and liability related to substantially all of its operating lease arrangements. ASU 2016-02 will be effective for the Company in the first quarter of its fiscal year ending June 30, 2020.

Income Taxes – In October 2016, the FASB issued ASU 2016-16, “Income Taxes” (Topic 740) (“ASU 2016-16”). ASU 2016-16 requires an entity to 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 fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual reporting period for which financial statements have not been issued or made available for issuance. ASU 2016-16 is effective for the Company in the first quarter of its fiscal year ending June 30, 2019. The Company does not expect this accounting standard to have a significant impact on its financial results when adopted.

Compensation – Stock Compensation – In May 2017, the FASB issued ASU 2017-09, “Compensation - Stock Compensation” (Topic 718): Scope of Modification Accounting (“ASU 2017-09”). The new guidance clarifies when a change to the terms or conditions of a share-based payment award must be accounted for as a modification. ASU 2017-09 is effective for fiscal years, and interim periods within those annual periods, beginning after December 15, 2017, with early adoption permitted. ASU 2017-09 is effective for the Company in the first quarter of its fiscal year ending June 30, 2019. The Company does not expect this accounting standard to have a significant impact on its financial results when adopted.

Comprehensive Income - In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”). ASU 2018-02 allows entities to elect to reclassify the income tax effects of the Tax Act on items within accumulated other comprehensive income to retained earnings and requires additional related disclosures. ASU 2018-02 is effective for the Company in the first quarter of its fiscal year ending June 30, 2020. The Company is currently evaluating the impact that ASU 2018-02 will have on its Consolidated Financial Statements.

No other new accounting pronouncement recently issued or newly effective had or is expected to have a material impact on the Consolidated Financial Statements.
