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. Certain accounts 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.

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.

Accounts Receivable [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 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.

Inventory, Policy [Policy Text Block]

Inventories

We operate primarily as a private-label contract manufacturer. We build 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.

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. During fiscal 2022 we recognized no impairment losses. We recognized $21,000 impairment losses during fiscal 2021.

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 obligations and annual pension expense. Key assumptions in measuring the plan obligations 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.

Cost of Goods and Service [Policy Text Block]

Cost of Goods Sold

Cost of goods sold includes raw material, labor, manufacturing overhead, and royalty expense.

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.

Research and development costs are expensed when incurred. Our research and development expenses for the last two fiscal years ended June 30 were $2.5 million for fiscal 2022 and $1.9 million for fiscal 2021. These costs were included in selling, general and administrative expenses and cost of goods sold.

Income Tax, Policy [Policy Text Block]

Income Taxes

The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted on March 27, 2020 in the United States. The CARES Act and related notices include several significant provisions, including delaying certain payroll tax payments, mandatory transition tax payments under the Tax Cuts and Jobs Act (“TCJ Act”), and estimated income tax payments. We filed an amended return for our fiscal 2015 and fiscal 2016 tax years under provisions of the CARES act, as discussed below.

On July 23, 2020, the Department of Treasury issued final regulations which provide an exclusion to the global intangible low-taxed income (GILTI) calculation on an elective basis. These regulations were effective September 21, 2020 and could be retroactively applied. Under these new regulations, we are able to exclude the GILTI calculation from our domestic taxable income if the deemed effective tax rate at our foreign subsidiary is greater than 18.9%. We assessed this rate, including the implementation of certain tax strategies, and we determined that our effective rate at NAIE was greater than 18.9% as of the year ended June 30, 2020. We reassessed our estimated taxes for fiscal 2020 and in the year ended June 30, 2021 we recorded a reduction to our fiscal 2020 estimated taxes of $0.4 million as a discrete benefit. As a result of this adjustment, our domestic tax return for fiscal 2020 reflected a net operating loss which, in accordance with the CARES ACT, we carried back to fiscal 2015 and fiscal 2016. Such carryback resulted in a rate differential that resulted in the recognition of a permanent discrete tax benefit of $0.3 million during the year ended June 30, 2021. For NAIE the result of this tax planning during the year ended June 30, 2021 was an additional foreign estimated tax benefit of $0.1 million.

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.

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 based on whether future taxable income will be generated during the periods in which those temporary differences become deductible. During the year ended June 30, 2022, there was no change to our valuation allowance.

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are measured and recorded using enacted tax rates for each of the jurisdictions in which we operate, and adjusted using 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 or expense 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, 2022 and June 30, 2021, we did not record any tax liabilities for uncertain tax positions.

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.

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 primarily concentrated with our three largest customers, whose receivable balances collectively represented 52.4% of gross accounts receivable at June 30, 2022 and 64.8% at June 30, 2021. As of June 30, 2022, we had a receivable balance of $3.4 million and as of June 30, 2021 we had a receivable balance of $3.5 million from a former contract manufacturing customer. We have recorded a bad debt reserve equal to 100% of this outstanding balance and thus did not reflect it in the percentages listed above.

Additionally, amounts due related to our beta-alanine raw material sales were 5.4% of gross accounts receivable at June 30, 2022 and 8.6% of gross accounts receivable at June 30, 2021. Concentrations of credit risk related to the remaining accounts receivable balances are limited due to the number of customers comprising our remaining customer base.
