Significant Accounting Policies  
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.
Management estimates

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

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, generally 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.  The Company did not have any restricted cash as of June 30, 2022 or 2021.
Allowance for accounts receivable

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

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 are expensed when incurred.  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 and (ii) items that have not been purchased in two years. 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. Items of which we have greater than a two-year supply are also reserved at 25% to 100%, depending on usage rates.  The parts identified are adjusted for recent order and quote activity to determine the final inventory allowance.
Property and equipment

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

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.  The Company did not record any impairment of long-lived assets during the fiscal years ended June 30, 2022 and 2021.  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

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.  The Company did not record any goodwill impairment during the fiscal years ended June 30, 2022 or 2021.
Leases

Leases. The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, other current liabilities and operating lease liabilities on the Company's consolidated balance sheet. Finance leases are included in property, plant and equipment, current portion of long-term debt and long-term debt, net of current portion on the consolidated balance sheets.

 

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, the Company uses an estimate of its incremental borrowing rate based on observed market data and other information available at the lease commencement date. The operating lease ROU assets also include any lease payments made and exclude lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. The Company does not record leases on the consolidated balance sheet with a term of one year or less. The Company does not separate lease and non-lease components but rather accounts for each separate component as a single lease component for all underlying classes of assets. Variable lease payments are expensed as incurred and are not included within the operating lease ROU asset and lease liability calculation. Variable lease payments primarily include reimbursements of costs incurred by lessors for common area maintenance and utilities. Lease expense for minimum operating lease payments is recognized on a straight-line basis over the lease term.
Income taxes

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 United States (“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 totaled approximately $5.5 million at June 30, 2022.  Of this amount, greater than 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.  Historically, we considered unremitted earnings held by our foreign subsidiaries to be permanently reinvested.  However, during fiscal 2020, we began declaring intercompany dividends to remit a portion of the earnings of our foreign subsidiaries to the U.S. parent company.  It is still our intent to reinvest a significant portion of earnings generated by our foreign subsidiaries, however we also plan to repatriate a portion of their earnings.

 

With respect to the funds generated by our foreign subsidiaries in China, the retained earnings of the legal entity must equal at least 50% of the registered capital before any funds can be repatriated.  During fiscal 2022 and 2021, we repatriated approximately $2.8 million and $4 million, respectively, from LPOIZ.  As of June 30, 2022, LPOIZ had approximately $3.9 million in retained earnings available for repatriation, and LPOI did not have any earnings available for repatriation, based on earnings accumulated through December 31, 2021, the end of the most recent statutory tax year, that remained undistributed as of June 30, 2022.  During fiscal year 2020 we began to accrue for the applicable Chinese withholding taxes on the portion of earnings that we intend to repatriate.  As of June 30, 2022 and 2021, accrued and unpaid withholding taxes were $40,000 and $100,000, respectively.

 

Beginning in fiscal year 2019, earnings from the Company’s non-U.S. subsidiaries were subject to the global intangible low-taxed income (“GILTI”) inclusion pursuant to U.S. income tax rules.  See Note 8, Income Taxes, to these Consolidated Financial Statements for additional information.
Revenue recognition

Revenue recognition – See Note 3, Revenue, to these Consolidated Financial Statements for additional information.    

VAT

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 VAT receivables and payables on a net basis in the accompanying Consolidated Financial Statements.  These amounts were not significant as of June 30, 2022 and 2021.
New product development

New product development costs are expensed as incurred.
Stock-based compensation

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.  Our directors, officers, and key employees were granted stock-based compensation through our Amended and Restated Omnibus Incentive Plan, as amended (the “Omnibus Plan”), through October 2018 and after that date, the 2018 Stock and Incentive Compensation Plan (the “SICP”). Most options granted under the Omnibus Plan and the SICP 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

Fair value of financial instruments. The Company accounts for financial instruments in accordance with the Financial Accounting Standards Board’s (“FASB”) 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 accounts receivable, 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 finance lease obligations and loans payable approximate their carrying values, based upon current rates available to us.  See Note 13, Loans Payable, to these Consolidated Financial Statements for additional information.  Management considers these fair value estimates to be level 2 fair value measurements.

 

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

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.
Comprehensive income

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

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

Recent accounting pronouncements. There are no new accounting pronouncements issued by the FASB that are not yet effective for the Company for the year ended June 30, 2022 that are expected to have a material impact on the Consolidated Financial Statements.
