NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash and Cash Equivalents

We consider all highly liquid investments with maturities of three months or less when purchased to be cash equivalents.

Concentration of Risk and Financial Instruments

Financial instruments potentially subject to significant concentrations of credit risk consist principally of cash equivalents, marketable securities, and accounts receivable.

Cash and cash equivalents have been maintained in financial institutions we believe have high credit quality, however, these accounts may not be federally insured.

We have invested our excess cash in corporate-backed and municipal-backed bonds and money market instruments. Our investment policy prescribes purchases of only high-grade securities and limits the amount of credit exposure to any one issuer.

Our customers are throughout the world. We generally do not require collateral from our customers, but we perform ongoing credit evaluations of their financial condition. More information on accounts receivable is contained in the paragraph titled “Accounts Receivable and Allowance for Credit Losses” of this note.

Additionally, we are dependent on critical suppliers including our packaging vendors and suppliers of certain raw silicon and semiconductor wafers that are incorporated in our products. Industry shortages and supply-chain disruptions in the past several years have increased the risks of supply interruptions.

Marketable securities

Our marketable securities consist of corporate bonds and money market funds. Marketable securities are initially recognized at cost. Marketable securities considered to be “purchased financial assets with credit deterioration” are initially recognized at cost, less any allowance for expected credit losses. Unrealized holding gains and losses are reported in other comprehensive income, net of applicable taxes, until realized. All marketable securities are carried on the balance sheet at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We use a three-level fair value hierarchy in estimating and reporting fair values of our marketable securities:

Level 1 – Securities whose fair values are determined using quoted prices in active markets for identical securities.

Level 2 – Securities whose fair values are determined using quoted prices for similar securities in active markets or quoted prices for identical securities in markets that are not active.

Level 3 – Securities whose fair values are determined using unobservable inputs.

Corporate bonds with remaining maturities of less than one year are classified as short-term and those with remaining maturities of one year or more are classified as long-term. We consider all highly liquid investments with maturities of three months or less when purchased, including money market funds, to be cash equivalents.

Accounts Receivable and Allowance for Credit Losses

We grant credit to customers in the normal course of business and at times may require customers to prepay for orders prior to shipment. Accounts receivable are recorded net of allowance for credit losses. We specifically analyze accounts receivable, historical credit losses, and customer creditworthiness when estimated allowance for credit losses.

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined by the first in, first out method. We record inventory reserves when we determine certain inventory is unlikely to be sold based on sales trends, turnover, competition, and other market factors.

Product Warranty

In general, we warranty our products to be free from defects in material and workmanship for one year.

Fixed Assets

Fixed assets are stated at cost. Depreciation of machinery and equipment is recorded over the estimated useful lives of the assets, generally five years, using the straight-line method. Amortization of leasehold improvements is recorded using the straight-line method over the lesser of the remaining term of the lease or five-year useful life. We record losses on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. We did not identify any indicators of impairment during fiscal 2024 or 2023. Depreciation expense related to fixed assets was $308,147 for fiscal 2024 and $196,738 for fiscal 2023.

Revenue Recognition

We recognize revenue when we satisfy performance obligations by the transfer of control of products or services to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those products or services. Revenue is disaggregated into product sales and contract research and development to depict the nature, amount, and timing of revenue recognition and economic characteristics of our business, and is represented within the financial statements.

We recognize revenue from product sales to customers and distributors when we satisfy our performance obligation, at a point in time, on product shipment or delivery to our customer or distributor as determined by agreed-on shipping terms. Shipping charges billed to customers are included in product sales and the related shipping costs are included in cost of sales. Under certain limited circumstances, our distributors may earn commissions for activities unrelated to their purchases of our products, such as for facilitating the sale of custom products or research and development contracts with third parties. We recognize any such commissions as selling, general, and administrative expenses. We recognize discounts provided to our distributors as reductions in revenue.

We recognize contract research and development revenue as the performance obligations are satisfied. Contracts have specifications unique to each customer and do not create an asset with an alternate use, and we have an enforceable right to payment for performance completed to date. We use the proportion of total contract consideration attributable to performance milestones achieved as the measurement of progress toward completion.

Accounts receivable is recognized when we have transferred a good or service to a customer and our right to receive consideration is unconditional through the completion of our performance obligation. A contract asset is recognized when we have a right to consideration from the transfer of goods or services to a customer but have not completed our performance obligation. A contract liability is recognized when we have been paid by a customer but have not yet satisfied the performance obligation by transferring goods or services. We had no material contract assets or contract liabilities as of March 31, 2024, or March 31, 2023.

Our performance obligations related to product sales and contract research and development contracts are satisfied in one year or less. Unsatisfied performance obligations represent contracts with an original expected duration of one year or less. As permitted under Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers, we are using the practical expedient not to disclose the value of these unsatisfied performance obligations. We also use the practical expedient in which we do not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between payment by the customer and the transfer of the promised goods or services to the customer will be one year or less.

Income Taxes

We account for income taxes using the asset and liability method. Deferred income taxes are provided for temporary differences between the financial reporting and tax bases of assets and liabilities. We provide valuation allowances against deferred tax assets if we determine that it is less likely than not that we will be able to utilize the deferred tax assets.

Research and Development Expense Recognition

Research and development costs are expensed as they are incurred. Customer-sponsored research and development costs are included in cost of sales.

Stock-Based Compensation

We measure stock-based compensation cost at the grant date based on the fair value of the award and recognize the compensation expense over the requisite service period, which is generally the vesting period. We recognize any forfeitures as they occur.

Net Income Per Share

Net income per basic share is computed based on the weighted average number of common shares issued and outstanding during the year. Net income per diluted share amounts assume the exercise of all stock options. The following table shows the components of diluted shares:

	Year Ended March 31,
	2024		2023
Weighted average common shares outstanding – basic		4,833,146		4,830,826
Dilutive effect of stock options		6,559		1,270
Shares used in computing net income per share – diluted		4,839,705		4,832,096

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Recently Adopted Accounting Standard

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Statements. ASU 2016-13 requires a financial asset (or a group of financial assets) to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. In November 2018 the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which clarifies codification and corrects unintended application of the guidance, and in November 2019, the FASB issued ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which clarifies or addresses specific issues about certain aspects of ASU 2016-13. In November 2019 the FASB issued ASU No. 2019-10, Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, and in February 2020 the FASB issued ASU No. 2020-02, Financial Instruments—Credit Losses (Topic 326) and Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842), both of which delay the effective date of ASU 2016-13 by three years for certain Smaller Reporting Companies such as us. In March 2020, the FASB issued ASU No. 2020-03, Codification Improvements to Financial Instruments; which modifies the measurement of expected credit losses of certain financial instruments. We adopted ASU No. 2016-13 beginning with the quarter ended June 30, 2023. The adoption resulted in disclosure changes and required us to consider the likelihood of default and to measure our allowance for credit losses over the contractual term of our receivables. The adoption did not have a material impact on the financial statements as of March 31, 2024 or April 1, 2023.

New Accounting Standards Not Yet Adopted

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 requires additional quantitative and qualitative income tax disclosures to enable financial statements users to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. For public business entities, ASU 2023-09 is effective for annual periods beginning after December 15, 2024, which will be fiscal 2026 for us. The adoption will result in disclosure changes only.

We do not expect the adoption of other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date to have a material impact on our financial statements when they are adopted.
