Accounting Policies [Abstract] |
Consolidation, Subsidiaries or Other Investments, Consolidated Entities, Policy [Policy Text Block] | Subsidiaries On January 22, 1999, Natural Alternatives International Europe S.A. (NAIE) was formed as our wholly-owned subsidiary, based in Manno, Switzerland. In September 1999, NAIE opened a manufacturing facility and currently possesses manufacturing capability in encapsulation, powders, tablets, finished goods packaging, quality control laboratory testing, warehousing, distribution and administration.
Consolidation, Policy [Policy Text Block] | Principles of Consolidation The consolidated financial statements include the accounts of Natural Alternatives International, Inc. (NAI) and our wholly-owned subsidiary, NAIE. All intercompany accounts and transactions have been eliminated. The functional currency of NAIE, our foreign subsidiary, is the U.S. Dollar. The financial statements of NAIE have been translated at either current or historical exchange rates, as appropriate, with gains and losses included in the consolidated statements of operations.
New Accounting Pronouncements, Policy [Policy Text Block] | Recent Accounting Pronouncements In March 2016, the FASB issued Accounting Standards Update No. 2016 - 02, Leases (Topic 842 ) (ASU 2016 - 02 ), which amends existing standards for leases to increase transparency and comparability among organizations by requiring recognition of lease assets and liabilities on the balance sheet and requiring disclosure of key information about such arrangements. ASU 2016 - 02 will be effective for us beginning in our first quarter of fiscal 2020. Early adoption is permitted. We continue to evaluate the impact of adopting the new standard on our consolidated financial statements and the timing and presentation of our adoption. In April 2016, the FASB issued Accounting Standards Update No. 2016 - 10, Revenue from Contracts with Customers (Topic 606 )(ASU 2016 - 10 ), which amends and adds clarity to certain aspects of the guidance set forth in the upcoming revenue standard (ASU 2014 - 09 ) related to identifying performance obligations and licensing. In May 2016, the FASB issued Accounting Standards Update No. 2016 - 11, Revenue Recognition (Topic 605 ) and Derivatives and Hedging (Topic 815 ) (ASU 2016 - 11 ), which amends and rescinds certain revenue recognition guidance previously released within ASU 2014 - 09. In May 2016 the FASB issued Accounting Standards Update No. 2016 - 12, Revenue from Contracts with Customers (Topic 606 ) (ASU 2016 - 12 ), which provides narrow scope improvements and practical expedients related to ASU 2014 - 09. ASU 2014 - 09 defines a five step process to achieve this core principle (that we should recognize revenue in an amount that reflects the consideration to which we expect to be entitled in exchange for goods or services provided) that requires more judgment and estimates within the revenue recognition process than are required under present U.S. GAAP. These judgments and estimates may include identifying each performance obligation in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each separate performance obligation. ASU 2016 - 12 also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant additional judgments and changes in existing judgments. All of these new standards will be effective for us concurrently with ASU 2014 - 09, beginning in our first quarter of fiscal 2019. We have completed our review of the impact of this new guidance and we do not expect our annual revenue to be materially different under Topic 606. The most significant change will be to our quarterly and annual financial statement disclosures. In August 2017, the FASB issued ASU 2017 - 12, Derivatives and Hedging (Topic 815 ): Targeted Improvements to Accounting for Hedging Activities. ASU 2017 - 12 is intended to improve and simplify accounting rules around hedge accounting and improve the disclosures of hedging arrangements. We are currently evaluating the impact of adopting the new standard on our consolidated financial statements. ASU 2017 - 12 will be effective for us beginning in our first quarter of fiscal 2020. On December 22, 2017, the SEC issued guidance under Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118” ) directing taxpayers to consider the impact of the U.S. legislation as “provisional” when it does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the change in tax law. In accordance with SAB 118, we have calculated our taxes for fiscal 2018 to the best of our ability and we do not expect any significant changes, however our estimated income tax could change once we complete our tax return and thus our tax expense for fiscal 2018 is considered provisional and is expected to be finalized by the end of the one -year measurement period ending December 22, 2018. In February 2018, the FASB issued ASU 2018 - 02, Income Statement-Reporting Comprehensive Income (Topic 220 ): Reclassification of Certain Tax Effect from Accumulated Other Comprehensive Income. ASU 2018 - 02 allows for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. We are currently evaluating the impact of adopting the new standard on our consolidated financial statements. ASU 2018 - 02 will be effective for us beginning in our first quarter of fiscal 2020. In February 2018, the FASB issued ASU 2018 - 03, Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825 - 10 ): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2018 - 03 is intended to improve certain aspects of recognition, measurement, presentation, and disclosure of certain financial instruments, i.e. forward contracts, purchased options and option liabilities. We do not expect this AUD to have a material impact on our consolidated financial statements. ASU 2018 - 03 will be effective for us beginning in our first quarter of fiscal 2019. In June 2018, the FASB issued ASU 2018 - 07, Compensation-Stock Compensation (Topic 718 ): Improvements to Nonemployee Share-Based Payment Accounting. The ASU clarifies that Topic 718 does not apply to share-based payments used to effectively provide financing to the issuer or awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. We are currently evaluating the impact of the new standard. ASU 2018 - 07 will be effective for us beginning in our first quarter of fiscal 2020.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and Cash Equivalents We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
Fair Value Measurement, Policy [Policy Text Block] | Fair Value of Financial Instruments Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. We use a three -level hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available under the circumstances. The fair value hierarchy is broken down into three levels based on the source of inputs. In general, fair values determined by Level 1 inputs use quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access. We classify cash, cash equivalents, and marketable securities balances as Level 1 assets. Fair values determined by Level 2 inputs are based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable or can be corroborated, either directly or indirectly by observable market data. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. These include certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. As of June 30, 2018 and June 30, 2017, we did not have any financial assets or liabilities classified as Level 1, except for cash and cash equivalents, and assets and liabilities related to our pension plan. We classify derivative forward exchange contracts as Level 2 assets and liabilities. The fair value of our forward exchange contracts as of June 30, 2018 included a net asset of $55,000 and a net liability of $55,000, with no right of offset. The fair value as of June 30, 2017 was a net liability of $521,000. The fair values were determined based on obtaining pricing from our bank and corroborating those values with a third party bank. As of June 30, 2018 and June 30, 2017, we did not have any financial assets or liabilities classified as Level 3. We did not transfer any assets or liabilities between any levels during fiscal 2018.
Trade and Other Accounts Receivable, Policy [Policy Text Block] | Accounts Receivable We perform ongoing credit evaluations of our customers and adjust credit limits based on payment history and customer credit-worthiness. An allowance for estimated doubtful accounts is maintained based on historical experience, including anticipated early payment discounts and identified customer credit issues. We monitor collections regularly and adjust the allowance for doubtful accounts as necessary to recognize any changes in credit exposure. Upon conclusion that a receivable is uncollectible, we record the respective amount as a charge against allowance for doubtful accounts. To date, such doubtful accounts reserves, in the aggregate, have been adequate to cover collection losses.
Finance, Loans and Leases Receivable, Policy [Policy Text Block] | Notes Receivable On September 30, 2017, we accepted a 12 -month note from Kaged Muscle, LLC (“Kaged Muscle”), one of our contract manufacturing customers, in exchange for $1.5 million of trade receivables due to us from Kaged Muscle. Kaged Muscle is one of our fastest growing sports nutrition customers and we executed this note receivable conversion to assist them with their near term financing needs. The note carries an interest rate of fifteen percent ( 15% ) per annum and is an interest only note secured by the assets of Kaged Muscle and a personal guarantee by the co-founder and President of Kaged Muscle. Interest is due quarterly and the note can be paid down at any time without penalty. We recognized $171,000 in interest income during the year ended June 30, 2018 associated with this note from Kaged Muscle.
Inventory, Policy [Policy Text Block] | Inventories We operate primarily as a private-label contract manufacturer that builds products based upon anticipated demand or following receipt of customer specific purchase orders. From time to time, we build inventory for private-label contract manufacturing customers under a specific purchase order with delivery dates that may subsequently be rescheduled or canceled at the customer’s request. We value inventory at the lower of cost ( first -in, first -out) or net realizable value on an item-by-item basis, including costs for raw materials, labor and manufacturing overhead. We establish reserves equal to all or a portion of the related inventory to reflect situations in which the cost of the inventory is not expected to be recovered. This requires us to make estimates regarding the market value of our inventory, including an assessment for excess and obsolete inventory. Once we establish an inventory reserve in a fiscal period, the reduced inventory value is maintained until the inventory is sold or otherwise disposed of. In evaluating whether inventory is stated at the lower of cost or net realizable value, management considers such factors as the amount of inventory on hand, the estimated time required to sell such inventory, the remaining shelf life and efficacy, the foreseeable demand within a specified time horizon and current and expected market conditions. Based on this evaluation, we record adjustments to cost of goods sold to adjust inventory to its net realizable value.
Property, Plant and Equipment, Policy [Policy Text Block] | Property and Equipment We state property and equipment at cost. Depreciation of property and equipment is provided using the straight-line method over their estimated useful lives, generally ranging from 1 to 39 years. We amortize leasehold improvements using the straight-line method over the shorter of the useful life of the improvement or the term of the lease. Maintenance and repairs are expensed as incurred. Significant expenditures that increase economic useful lives of property or equipment are capitalized.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Impairment of Long-Lived Assets We periodically evaluate the carrying value of long-lived assets to be held and used when events and circumstances indicate that the carrying amount of an asset may not be recovered. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. We did not recognize any impairment losses during fiscal 2018 or fiscal 2017.
Derivatives, Policy [Policy Text Block] | Derivative Financial Instruments We currently may use derivative financial instruments in the management of our foreign currency exchange risk inherent in our forecasted transactions denominated in Euros. We may hedge our foreign currency exposures by entering into offsetting forward exchange contracts and currency options. To the extent we use derivative financial instruments, we account for them using the deferral method, which recognizes income or expense at the time when such instruments are intended to hedge identifiable, firm foreign currency commitments or anticipated transactions and are designated as, and effective as, hedges. Foreign exchange exposures arising from certain transactions that do not meet the criteria for the deferral method are marked-to-market through the Consolidated Statements of Operations and Comprehensive Income. We recognize any unrealized gains and losses associated with derivative instruments in income in the period in which the underlying hedged transaction is realized. To the extent the derivative instrument is deemed ineffective we would recognize the resulting gain or loss in income at that time. As of June 30, 2018, we held derivative contracts designated as cash flow hedges primarily to protect against the foreign exchange risks inherent in our forecasted sales of products at prices denominated in currencies other than the U.S. Dollar. As of June 30, 2018, the notional amounts of our foreign exchange contracts were $34.4 million (€ 29.0 million). These contracts will mature over the next 14 months
Pension and Other Postretirement Plans, Policy [Policy Text Block] | Defined Benefit Pension Plan We formerly sponsored a defined benefit pension plan. Effective June 21, 1999, we adopted an amendment to freeze benefit accruals to the participants. The plan obligation and related assets of the plan are presented in the notes to the consolidated financial statements. Plan assets, which consist primarily of marketable equity and debt instruments, are valued based upon third party market quotations. Independent actuaries, through the use of a number of assumptions, determine plan obligation and annual pension expense. Key assumptions in measuring the plan obligation include the discount rate and estimated future return on plan assets. In determining the discount rate, we use an average long-term bond yield. Asset returns are based on the historical returns of multiple asset classes to develop a risk free rate of return and risk premiums for each asset class. The overall rate for each asset class was developed by combining a long-term inflation component, the risk free rate of return and the associated risk premium. A weighted average rate is developed based on the overall rates and the plan’s asset allocation.
Revenue Recognition, Policy [Policy Text Block] | Revenue Recognition To recognize revenue, four basic criteria must be met: 1 ) there is evidence that an arrangement exists; 2 ) delivery has occurred; 3 ) the fee is fixed or determinable; and 4 ) collectability is reasonably assured. Revenue from sales transactions where the buyer has the right to return the product is recognized at the time of sale only if (a) the seller’s price to the buyer is substantially fixed or determinable at the date of sale; (b) the buyer has paid the seller, or the buyer is obligated to pay the seller and the obligation is not contingent on resale of the product; (c) the buyer’s obligation to the seller would not be changed in the event of theft or physical destruction or damage of the product; (d) the buyer acquiring the product for resale has economic substance apart from that provided by the seller; (e) the seller does not have significant obligations for future performance to directly bring about resale of the product by the buyer; and (f) the amount of future returns can be reasonably estimated. We recognize revenue upon determination that all criteria for revenue recognition have been met. The criteria are usually met at the time title passes to the customer, which usually occurs upon shipment. Revenue from shipments where title passes upon delivery is deferred until the shipment has been delivered. We record reductions to gross revenue for estimated returns of private-label contract manufacturing products and beta-alanine raw material sales. The estimated returns are based on the trailing six months of gross sales and our historical experience for both private-label contract manufacturing and beta-alanine raw material product returns. However, the estimate for product returns does not reflect the impact of a potential large product recall resulting from product nonconformance or other factors as such events are not predictable nor is the related economic impact estimable. On August 7, 2017, we entered into three agreements (“Agreements”), with The Juice Plus+ Company LLC (“Juice Plus+”). The Agreements are an Exclusive Manufacturing Agreement, a Restricted Stock Award Agreement, and an Irrevocable Proxy. Pursuant to the Exclusive Manufacturing Agreement, Juice Plus+ has granted us exclusive rights to manufacture and supply them with certain of their products within 24 countries where Juice Plus+ currently sells those products. Pursuant to the Restricted Stock Award Agreement, NAI has granted 500,000 shares of NAI common stock to Juice Plus+, (the “Shares”), and Juice Plus+ has agreed the Shares are subject to certain restrictions and risk of forfeiture. Pursuant to the Irrevocable Proxy, Juice Plus+ has also granted to the NAI Board of Directors the right to vote the Shares that remain subject to the risk of forfeiture. Each Agreement is for a term of 5 years, and each may be terminated by either party only upon the occurrence of specified events. The expense associated with the Shares granted to Juice Plus+ is recorded as a reduction to revenue. We recorded $898,000 of expense as an offset to net sales during the year ended June 30, 2018. We currently own certain U.S. patents, and each patent’s corresponding foreign patent applications. All of these patents and patent rights relate to the ingredient known as beta-alanine marketed and sold under the CarnoSyn® and SR CarnoSyn® trade names. We recorded beta-alanine raw material sales and royalty and licensing income as a component of revenue in the amount of $21.4 million during fiscal 2018 and $26.9 million during fiscal 2017. These royalty income and raw material sale amounts resulted in royalty expense paid to the original patent holders from whom NAI acquired its patents and patent rights. We recognized royalty expense as a component of cost of goods sold in the amount of $854,000 during fiscal 2018 and $1.0 million during fiscal 2017.
Cost of Sales, Policy [Policy Text Block] | Cost of Goods Sold Cost of goods sold includes raw material, labor, manufacturing overhead, and royalty expense.
Shipping and Handling Cost, Policy [Policy Text Block] | Shipping and Handling Costs We include fees earned on the shipment of our products to customers in sales and include costs incurred on the shipment of product to customers in costs of goods sold.
Research and Development Expense, Policy [Policy Text Block] | Research and Development Costs As part of the services we provide to our private-label contract manufacturing customers, we may perform, but are not obligated to perform, certain research and development activities related to the development or improvement of their products. While our customers typically do not pay directly for this service, the cost of this service is included as a component of the price we charge to manufacture and deliver their products. We also direct and participate in clinical research studies, often in collaboration with scientists and research institutions, to validate the benefits of a product and provide scientific support for product claims and marketing initiatives. We believe our commitment to research and development, as well as our facilities and strategic alliances with our suppliers and customers, allow us to effectively identify, develop and market high-quality and innovative products. Research and development costs are expensed when incurred. Our research and development expenses for the last two fiscal years ended June 30 were $1.5 million for fiscal 2018 and $1.6 million for fiscal 2017. These costs were included in selling, general and administrative expenses and cost of goods sold.
Advertising Costs, Policy [Policy Text Block] | Advertising Costs We expense the production costs of advertising the first time the advertising takes place. We incurred and expensed advertising costs in the amount of $2.4 million during the fiscal year ended June 30, 2018 and $598,000 during fiscal 2017. These costs were included in selling, general and administrative expenses.
Income Tax, Policy [Policy Text Block] | Income Taxes The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. Among other things, the Act reduces the U.S. federal corporate tax rate to 21% and requires companies to pay a one -time deemed repatriation transition tax on earnings of U.S.-owned foreign subsidiaries that were previously tax deferred. In certain cases, as described below and in accordance with SAB 118, we made a reasonable estimate of the effects on our existing deferred tax balances and the one -time transition tax, for which we recognized a provisional amount as a discrete component of our provision for income taxes. The impact of the Tax Legislation may differ from these estimates, possibly materially, during the one -year measurement period ending December 22, 2018 due to, among other things, further refinement of our calculations, changes in interpretations and assumptions we made, guidance that may be issued and actions we may take as a result of the Act. To determine our quarterly provision for income taxes, we use an estimated annual effective tax rate that is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions to which we are subject. Certain significant or unusual items are separately recognized as discrete items in the quarter in which they occur and can be a source of variability in the effective tax rate from quarter to quarter. We recognize interest and penalties related to uncertain tax positions, if any, as an income tax expense. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are measured using enacted tax rates for each of the jurisdictions in which we operate, and the 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. We account for uncertain tax positions using the more-likely-than- not recognition threshold. It is our policy to establish reserves based on management’s assessment of exposure for certain positions taken in previously filed tax returns that may become payable upon audit by tax authorities. Our tax reserves are analyzed quarterly and adjustments are made as events occur that we believe warrant adjustments to the reserves. Our practice is to recognize interest and/or penalties related to income tax matters in income tax expense. As of June 30, 2018 and June 30, 2017, we had not recorded any tax liabilities for uncertain tax positions. We record valuation allowances to reduce our deferred tax assets to an amount that we believe is more likely than not to be realized. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will ultimately be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. During the year ended June 30, 2018, there was no change to our valuation allowance. We are subject to taxation in the U.S., Switzerland and various U.S. state jurisdictions. Our tax returns for the fiscal years ended June 30, 2015 and forward are subject to examination by U.S. tax authorities and for fiscal years ended June 30, 2007 and forward are subject to examination by state tax authorities. Our tax filings for the fiscal year ended June 30, 2015 and forward are subject to examination by Swiss tax authorities.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | Stock-Based Compensation We have an omnibus incentive plan that was approved by our Board of Directors effective as of October 15, 2009 and approved by our stockholders at the Annual Meeting of Stockholders held on November 30, 2009. Under the 2009 Plan, we may grant nonqualified and incentive stock options and other stock-based awards to employees, non-employee directors and consultants. Our prior equity incentive plan was terminated effective as of November 30, 2009. We estimate the fair value of stock option awards at the date of grant using the Black-Scholes option valuation model. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Option valuation models require the use of highly subjective assumptions. Black-Scholes uses assumptions related to volatility, the risk-free interest rate, the dividend yield (which we assume to be zero, as we have not paid any cash dividends) and employee exercise behavior. Expected volatilities used in the model are based on the historical volatility of our stock price. The risk-free interest rate is derived from the U.S. Treasury yield curve in effect in the period of grant. The expected life of stock option grants is derived from historical experience. The fair value of restricted stock shares granted is based on the market price of our common stock on the date of grant. We amortize the estimated fair value of our stock awards to expense over the related vesting periods. We recognize forfeitures as they occur. We did not grant any options during fiscal 2018 or 2017. We did not have any options exercised during fiscal 2018 or fiscal 2017. All remaining outstanding stock options are fully vested and all related compensation cost was fully recognized at June 30, 2014. No options vested during the fiscal years ended June 30, 2018 and June 30, 2017. During fiscal 2018, we granted a total of 175,000 restricted stock shares to the members of our Board of Directors and certain key members of our management team pursuant to the 2009 Plan. During fiscal 2017, we granted a total of 155,000 restricted stock shares to the members of our Board of Directors and certain key members of our management team pursuant to the 2009 Plan. These restricted stock grants vest over three or five years from the date of grant and the unvested shares cannot be sold or otherwise transferred and the rights to receive dividends, if declared by our Board of Directors, are forfeitable until the shares become vested. There were 458,012 vested restricted stock shares as of June 30, 2018 and there were 319,355 vested restricted stock shares as of June 30, 2017. The total remaining unrecognized compensation cost related to unvested restricted stock shares amounted to $3.1 million at June 30, 2018 and the weighted average remaining requisite service period of unvested restricted stock shares was 2.6 years. The weighted average fair value of restricted stock shares granted during fiscal 2018 was $11.30 per share. The weighted average fair value of restricted stock shares granted during fiscal 2017 was $8.82 per share.
Use of Estimates, Policy [Policy Text Block] | Use of Estimates Our management has made a number of estimates and assumptions relating to the reporting of assets and liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities to prepare these consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP). Actual results could differ from those estimates and our assumptions may prove to be inaccurate.
Earnings Per Share, Policy [Policy Text Block] | Net Income per Common Share We compute basic net income per common share using the weighted average number of common shares outstanding during the period, and diluted net income per common share using the additional dilutive effect of all dilutive securities. The dilutive impact of stock options and restricted shares account for the additional weighted average shares of common stock outstanding for our diluted net income per common share computation. We calculated basic and diluted net income per common share as follows (in thousands, except per share data):
|  | For the Years Ended June 30, |
|  | 201 8 |  |  | 201 7 |
Numerator |  |  |  |  |  |  |  |
Net income |  | $ | 5,051 |  |  | $ | 7,235 |
Denominator |  |  |  |  |  |  |  |
Basic weighted average common shares outstanding |  |  | 6,641 |  |  |  | 6,577 |
Dilutive effect of stock options and restricted stock shares |  |  | 245 |  |  |  | 79 |
Diluted weighted average common shares outstanding |  |  | 6,886 |  |  |  | 6,656 |
Basic net income per common share |  | $ | 0.76 |  |  | $ | 1.10 |
Diluted net income per common share |  | $ | 0.73 |  |  | $ | 1.09 |
We excluded shares related to restricted stock totaling 41,661 shares for the year ended June 30, 2018, as their impact would have been anti-dilutive. No shares related to stock options or restricted stock were excluded for the year ended June 30, 2017.
Concentration Risk, Credit Risk, Policy [Policy Text Block] | Concentrations of Credit Risk Financial instruments that subject us to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We place our cash and cash equivalents with highly rated financial institutions. Credit risk with respect to receivables is concentrated with our three largest customers, whose receivable balances collectively represented 76.6% of gross accounts receivable at June 30, 2018 and 65.6% at June 30, 2017. Additionally, amounts due related to our beta-alanine raw material sales were 17.3% of gross accounts receivable at June 30, 2018, and 21.3% of gross accounts receivable at June 30, 2017. Concentrations of credit risk related to the remaining accounts receivable balances are limited due to the number of customers comprising our remaining customer base.
