NVE CORPORATION
NOTES TO FINANCIAL STATEMENTS
(Unaudited)

NOTE 1. DESCRIPTION OF BUSINESS
     We develop and sell devices that use spintronics, a nanotechnology that relies on electron spin rather than electron charge to acquire, store, and transmit information.

NOTE 2. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
     The accompanying unaudited financial statements of NVE Corporation are prepared consistent with accounting principles generally accepted in the United States and in accordance with Securities and Exchange Commission rules and regulations. In the opinion of management, these financial statements reflect all adjustments, consisting only of normal and recurring adjustments, necessary for a fair presentation of the financial statements. Although we believe that the disclosures are adequate to make the information presented not misleading, it is suggested that these unaudited financial statements be read in conjunction with the audited financial statements and the notes included in our latest annual financial statements included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2018. The results of operations for the quarter or six months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the full fiscal year ending March 31, 2019.

Significant Accounting Policies
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, 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, upon product shipment or delivery to our customer or distributor as determined by agreed upon shipping terms. Shipping charges billed to customers are included in product sales and the related shipping costs are included in selling, general, and administrative expenses. 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 over a period of time as the performance obligation is satisfied over a period of time rather than a point in time. 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 recognize revenue over a period of time using costs incurred as the measurement of progress towards 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 September 30, 2018 or March 31, 2018.

     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.

NOTE 3. RECENTLY ISSUED ACCOUNTING STANDARDS
Recently Adopted Accounting Standards
     In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. The amendments in ASU 2018-13 will be effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, which will be fiscal 2021 for us. Early adoption is permitted for the removed disclosures and delayed adoption is permitted until fiscal 2021 for the new disclosures. We adopted ASU 2018-13 early, effective the quarter ended September 30, 2018. The removed and modified disclosures were adopted on a retrospective basis and the new disclosures on a prospective basis. The adoption did not have a significant effect on our financial statements.
 
     In February 2018, the FASB issued ASU No. 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220). ASU 2018-02 addresses the effect of the change in the U.S. federal corporate tax rate on items within accumulated other comprehensive income or loss due to the enactment of the Act “To provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018” (the “Tax Reform Act”) on December 22, 2017. The guidance will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, which will be fiscal 2020 for us. Early adoption is permitted, and we adopted ASU 2018-02 in the quarter ended June 30, 2018. The adoption resulted in a $60,365 reclassification from accumulated other comprehensive loss to retained earnings due to the change in the federal corporate tax rate.
 
     In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments, which made eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. We adopted ASU 2016-15 retrospectively in the quarter ended June 30, 2018. The adoption did not have a significant impact on our financial statements.

     In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The amendment changed the accounting for and financial statement presentation of equity investments, other than those accounted for under the equity method of accounting or those that result in consolidation of the investee. The amendment provides clarity on the measurement methodology to be used for the required disclosure of fair value of financial instruments measured at amortized cost on the balance sheet and clarifies that an entity should evaluate the need for a valuation allowance on deferred tax assets related to available-for-sale securities in combination with the entity’s other deferred tax assets, among other changes. We adopted ASU 2016-01 retrospectively in the quarter ended June 30, 2018. The adoption did not have a significant impact on our financial statements.
 
     In May 2014, the FASB issued ASU No. 2014-09, which superseded the revenue recognition requirements in Accounting Standards Codification 605, Revenue Recognition. 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. It 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. We adopted the guidance using the modified retrospective method to contracts that were not complete as of April 1, 2018. The adoption did not have significant impact on our financial statements.
 
     Information regarding all other applicable recently issued accounting standards, on which our position have not changed since our latest annual financial statements, are contained in the financial statements included in our Annual Report on Form 10-K for the year ended March 31, 2018.

New Accounting Standard Not Yet Adopted
     In February 2016, the FASB issued ASU No. 2016-02, Lease Accounting. ASU 2016-02 requires recognition of lease assets and lease liabilities on the balance sheet of lessees. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842 (Leases), which provides narrow amendments to clarify how to apply certain aspects of the new lease standard. The guidance will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, which will be fiscal 2020 for us. In July 2018, the FASB issued ASU No. 2018-11, Leases Topic (842): Targeted Improvements. This ASU provides companies an option to apply the transition provisions of the new lease standard at its adoption date instead of at the earliest comparative period presented in its financial statements. We expect to adopt the new lease guidance using the newly-approved transition method. We expect to recognize a liability and corresponding asset associated with in-scope operating and finance leases but are still in the process of determining those amounts and the processes required to account for leasing activity on an ongoing basis.

NOTE 4. NET INCOME PER SHARE
     Net income per basic share is computed based on the weighted-average number of common shares issued and outstanding during each period. Net income per diluted share amounts assume exercise of all stock options. The following tables show the components of diluted shares:
 

	Quarter Ended Sept. 30
	2018	2017
Weighted average common shares outstanding – basic	4,843,032	4,841,010
Dilutive effect of stock options	9,612	4,622
Shares used in computing net income per share – diluted	4,852,644	4,845,632

	Six Months Ended Sept. 30
	2018	2017
Weighted average common shares outstanding – basic	4,842,524	4,841,010
Dilutive effect of stock options	8,548	4,897
Shares used in computing net income per share – diluted	4,851,072	4,845,907

NOTE 5. FAIR VALUE OF FINANCIAL INSTRUMENTS
     Our corporate bonds and money market funds are classified as available-for-sale securities and carried at estimated fair value. Unrealized holding gains and losses are included in accumulated other comprehensive income (loss) in the statement of shareholders’ equity. Corporate bonds with remaining maturities less than one year are classified as short-term, and those with remaining maturities greater than one year 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. Gains and losses on marketable security transactions are reported on the specific-identification method.

     The fair value of our available-for-sale securities as of September 30, 2018 by maturity were as follows:

Total		<1 Year		1–3 Years		3–5 Years
$	76,576,286	$	29,716,134	$	22,784,235	$	24,075,917

     Total available-for-sale securities represented approximately 89% of our total assets. Marketable securities as of September 30, 2018 had remaining maturities between one and 55 months.

     Generally accepted accounting principles establish a framework for measuring fair value, provide a definition of fair value, and prescribe required disclosures about fair-value measurements. Generally accepted accounting principles define fair value as the price that would be received to sell an asset or paid to transfer a liability. Fair value is a market-based measurement that should be determined using assumptions that market participants would use in pricing an asset or liability. Generally accepted accounting principles utilize a valuation hierarchy for disclosure of fair value measurements. The categorization within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The categories within the valuation hierarchy are described as follows:

     Level 1 – Financial instruments with quoted prices in active markets for identical assets or liabilities.

     Level 2 – Financial instruments with quoted prices in active markets for similar assets or liabilities. Level 2 fair value measurements are determined using either prices for similar instruments or inputs that are either directly or indirectly observable, such as interest rates.

     Level 3 – Inputs to the fair value measurement are unobservable inputs or valuation techniques.

     Money market funds are included on the balance sheets in “Cash and cash equivalents.” Corporate bonds are included on the balance sheets in “Marketable securities, short term” and “Marketable securities, long term.”

     We did not consider any of our available-for-sale securities to be impaired as of September 30, 2018. None of the securities were impaired at acquisition, and subsequent declines in fair value are not attributed to declines in credit quality. When evaluating for impairment we assess indicators that include, but are not limited to, earnings performance, changes in underlying credit ratings, market conditions, bona fide offers to purchase or sell, and ability to hold until maturity. Because we believe it is more likely than not we will recover the cost basis of our investments, we did not consider any of our marketable securities to be impaired as of September 30, 2018.

NOTE 7. STOCK-BASED COMPENSATION
     Stock-based compensation expense was $93,360 for the second quarter and first six months of fiscal 2019, and $40,920 for the second quarter and first six months of fiscal 2018. Stock-based compensation expenses for the quarters and six months ended September 30, 2018 and 2017 were due to the automatic issuance to our non-employee directors of options to purchase 1,000 shares of stock on their reelection to our Board. We calculate the share-based compensation expense using the Black-Scholes standard option-pricing model. The increase in stock-based compensation expense for fiscal 2019 compared to fiscal 2018 was due to an increase in the model valuation for the same number of options to purchase shares.
 
NOTE 8. INCOME TAXES
     Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

     The Act “To provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018” (the “Tax Reform Act”) was enacted December 22, 2017. The Tax Reform Act reduced certain Federal corporate income tax rates effective January 1, 2018 and changed certain other provisions. As a result of the Tax Reform Act, our tax rate decreased to an estimated 18% for fiscal 2019 from 30% for fiscal 2018.
 
     We had no unrecognized tax benefits as of September 30, 2018, and we do not expect any significant unrecognized tax benefits within 12 months of the reporting date. We recognize interest and penalties related to income tax matters in income tax expense. As of September 30, 2018 we had no accrued interest related to uncertain tax positions. The tax years 1999 and 2014 through 2017 remain open to examination by the major taxing jurisdictions to which we are subject.
 
NOTE 9. STOCK REPURCHASE PROGRAM
     On January 21, 2009 we announced that our Board of Directors authorized the repurchase of up to $2,500,000 of our Common Stock, and on August 27, 2015 we announced that our Board authorized $5,000,000 of additional repurchases. We did not repurchase any of our Common Stock under the program during the quarter ended September 30, 2018. The remaining authorization was $4,540,806 as of September 30, 2018. The Repurchase Program may be modified or discontinued at any time without notice.

NOTE 10. SUBSEQUENT EVENTS
     On October 17, 2018 we announced that our Board had declared a quarterly cash dividend of $1.00 per share of Common Stock to be paid November 30, 2018 to shareholders of record as of the close of business October 29, 2018.
 
Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
Forward-looking statements
     Some of the statements made in this Report or in the documents incorporated by reference in this Report and in other materials filed or to be filed by us with the Securities and Exchange Commission (“SEC”) as well as information included in verbal or written statements made by us constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are subject to the safe harbor provisions of the reform act. Forward-looking statements may be identified by the use of the terminology such as may, will, expect, anticipate, intend, believe, estimate, should, or continue, or the negatives of these terms or other variations on these words or comparable terminology. To the extent that this Report contains forward-looking statements regarding the financial condition, operating results, business prospects or any other aspect of NVE, you should be aware that our actual financial condition, operating results and business performance may differ materially from that projected or estimated by us in the forward-looking statements. We have attempted to identify, in context, some of the factors that we currently believe may cause actual future experience and results to differ from their current expectations. These differences may be caused by a variety of factors, including but not limited to risks related to our reliance on several large customers for a significant percentage of revenue, uncertainties related to the economic environments in the industries we serve, uncertainties related to future contract research and development revenue, uncertainties related to the impact of Federal tax reform, uncertainties related to future stock repurchases and dividend payments, and other specific risks that may be alluded to in this Report or in the documents incorporated by reference in this Report.

     Further information regarding our risks and uncertainties are contained in Part I, Item 1A “Risk Factors” of our Annual Report on Form 10-K for the year ended March 31, 2018.

Quarter ended September 30, 2018 compared to quarter ended September 30, 2017
     The table shown below summarizes the percentage of revenue and quarter-to-quarter changes for various items:

	Percentage of Revenue Quarter Ended Sept. 30				Quarter- to-Quarter Change
	2018		2017
Revenue
Product sales	94.0	%	91.3	%	10.5	%
Contract research and development	6.0	%	8.7	%	(25.9	)%
Total revenue	100.0	%	100.0	%	7.3	%

Provision for income taxes	12.8	%	21.3	%	(35.3	)%
Net income	57.1	%	45.2	%	35.5	%

 
     Total revenue for the quarter ended September 30, 2018 (the second quarter of fiscal 2019) increased 7% compared to the quarter ended September 30, 2017 (the second quarter of fiscal 2018). The increase was due to an 10% increase in product sales, partially offset by a 26% decrease in contract research and development revenue.

     The increase in product sales from the prior-year quarter was primarily due to increased purchase volumes by existing customers and new customers. The decrease in contract research and development revenue was due to the completion of certain contracts.

     Gross profit margin increased to 82% of revenue for the second quarter of fiscal 2019 compared to 81% for the second quarter of fiscal 2018, due to a more profitable revenue mix.

     Total expenses decreased 2% for the second quarter of fiscal 2019 compared to the second quarter of fiscal 2018 due to a 6% decrease in research and development expense, partially offset by a 8% increase in selling, general, and administrative expense. The decrease in research and development expense was due to the timing of new product development expenses. The increase in selling, general, and administrative expense was primarily due to an increase in noncash stock-based compensation expense to $93,360 from $40,920. The increase in stock-based compensation expense for fiscal 2019 compared to fiscal 2018 was due to an increase in the model valuation for the same number of options to purchase shares.

     Interest income for the second quarter of fiscal 2019 increased 14% due to an increase in the average interest rates on our marketable securities, partially offset by a decrease in our securities.

     Our effective tax rate was 18% of net income before taxes for the quarter compared to 32% in the prior-year quarter. The decrease was due to the effect of a decrease in the Federal tax rate and certain other provisions with the enactment of the Tax Reform Act. See Note 8 to the financial statements for more information on income taxes.

     The 35% increase in net income in the second quarter of fiscal 2019 compared to the prior-year quarter was primarily due to an increase in product sales and a decrease in the Federal tax rate.

Provision for income taxes	12.6	%	21.0	%	(39.9	)%
Net income	56.3	%	44.2	%	27.4	%

 
     Total revenue for the six months ended September 30, 2018 increased slightly compared to the six months ended September 30, 2017, as a 5% increase in product sales was nearly offset by a 48% decrease in contract research and development revenue.

     The increase in product sales from the prior-year period was due to increased purchase volumes by existing customers and new customers. The decrease in contract research and development revenue was due to the completion of certain contracts.

     Gross profit margin increased to 81% of revenue for the second quarter of fiscal 2019 compared to 78% for the second quarter of fiscal 2018, due to a more profitable revenue mix.

     Total expenses decreased 1% for the first six months of fiscal 2019 compared to the first six months of fiscal 2018, due to a 6% decrease in selling, general, and administrative expense, partially offset by a 1% increase in research and development expense. The decrease in selling, general, and administrative expense was due to staffing changes.

     Our effective tax rate was 18% of net income before taxes for the first six months of fiscal 2019, compared to 32% in the prior-year period. The decrease was due to the effect of a decrease in the Federal tax rate and certain other provisions with the enactment of the Tax Reform Act. See Note 8 to the financial statements for more information on income taxes.

     The 27% increase in net income in the first six months of fiscal 2019 compared to the prior-year period was primarily due to an increase in product sales, an increase in gross profit margin, and a decrease in the Federal tax rate, partially offset by a decrease in contract research and development revenue.

Liquidity and capital resources
Overview
     Cash and cash equivalents were $6,047,918 as of September 30, 2018 compared to $4,755,082 as of March 31, 2018. The $1,292,836 increase in cash and cash equivalents during the six months ended September 30, 2018 was due to $8,270,118 in net cash provided by operating activities and $2,582,288 of cash provided by investing activities, partially offset by $9,559,570 of net cash used in financing activities. We currently believe our working capital and cash generated from operations will be adequate for our needs at least for the next 12 months.

Investing Activities
     Cash provided by investing activities in the six months ended September 30, 2018 was due to $9,300,000 of marketable security maturities, partially offset by $6,679,727 of purchases of marketable securities and $37,985 of purchases of fixed assets.
 
Financing Activities
     Cash used in financing activities in the first six months of fiscal 2019 was due to $9,684,020 of cash dividends paid to shareholders, partially offset by $124,450 of proceeds from the sale of common stock from stock option exercises. In addition to the dividends already paid in fiscal 2019, on October 17, 2018 we announced that our Board had declared a cash quarterly dividend of $1.00 per share of common stock, or $4,844,010 based on shares outstanding as of October 12, 2018, to be paid November 30, 2018. We plan to fund dividends through cash provided by operating activities and proceeds from maturities and sales of marketable securities. All future dividends will be subject to Board approval and subject to the company’s results of operations, cash and marketable security balances, estimates of future cash requirements, and other factors the Board may deem relevant. Furthermore, dividends may be modified or discontinued at any time without notice.
 
Item 4. Controls and Procedures.
Disclosure Controls and Procedures
     Management, with the participation of the Chief Executive Officer and Chief Financial Officer, has performed an evaluation of our disclosure controls and procedures that are defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (the “Exchange Act”) as of the end of the period covered by this Report. This evaluation included consideration of the controls, processes, and procedures that are designed to ensure that information required to be disclosed by us in the reports we file under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as September 30, 2018, our disclosure controls and procedures were effective.

Changes in Internal Controls
     During the quarter ended September 30, 2018, there was no change in our internal control over financial reporting that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

     The accompanying unaudited financial statements of NVE Corporation are prepared consistent with accounting principles generally accepted in the United States and in accordance with Securities and Exchange Commission rules and regulations. In the opinion of management, these financial statements reflect all adjustments, consisting only of normal and recurring adjustments, necessary for a fair presentation of the financial statements. Although we believe that the disclosures are adequate to make the information presented

not

misleading, it is suggested that these unaudited financial statements be read in conjunction with the audited financial statements and the notes included in our latest annual financial statements included in our Annual Report on Form

Significant Accounting Policies

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, 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, upon product shipment or delivery to our customer or distributor as determined by agreed upon shipping terms. Shipping charges billed to customers are included in product sales and the related shipping costs are included in selling, general, and administrative expenses. 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 over a period of time as the performance obligation is satisfied over a period of time rather than a point in time. 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 recognize revenue over a period of time using costs incurred as the measurement of progress towards 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

September 

30,

2018

or

March 

31,

2018.

     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.

NOTE

FAIR VALUE OF FINANCIAL INSTRUMENTS

     Our corporate bonds and money market funds are classified as available-for-sale securities and carried at estimated fair value. Unrealized holding gains and losses are included in accumulated other comprehensive income (loss) in the statement of shareholders’ equity. Corporate bonds with remaining maturities less than

one

year are classified as short-term, and those with remaining maturities greater than

one

year 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. Gains and losses on marketable security transactions are reported on the specific-identification method.

     The fair value of our available-for-sale securities as of

September 

30,

2018

by maturity were as follows:

Total		<1 Year		1–3 Years		3–5 Years
$	76,576,286	$	29,716,134	$	22,784,235	$	24,075,917

     Total available-for-sale securities represented approximately

89%

of our total assets. Marketable securities as of

September 

30,

2018

had remaining maturities between

one

and

55

 months.

     Generally accepted accounting principles establish a framework for measuring fair value, provide a definition of fair value, and prescribe required disclosures about fair-value measurements. Generally accepted accounting principles define fair value as the price that would be received to sell an asset or paid to transfer a liability. Fair value is a market-based measurement that should be determined using assumptions that market participants would use in pricing an asset or liability. Generally accepted accounting principles utilize a valuation hierarchy for disclosure of fair value measurements. The categorization within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The categories within the valuation hierarchy are described as follows:

     Level

1

– Financial instruments with quoted prices in active markets for identical assets or liabilities.

     Level

2

– Financial instruments with quoted prices in active markets for similar assets or liabilities. Level 

2

fair value measurements are determined using either prices for similar instruments or inputs that are either directly or indirectly observable, such as interest rates.

     Level

3

– Inputs to the fair value measurement are unobservable inputs or valuation techniques.

     Money market funds are included on the balance sheets in “Cash and cash equivalents.” Corporate bonds are included on the balance sheets in “Marketable securities, short term” and “Marketable securities, long term.”

     The following table shows the estimated fair value of assets that were accounted for at fair value on a recurring basis:

attributed to declines in credit quality. When evaluating for impairment we assess indicators that include, but are

INCOME TAXES

     Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

     The Act “To provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year

and changed certain other provisions. As a result of the Tax Reform Act, our tax rate decreased to an estimated

18%

for fiscal

Revenue Recognition, Sales of Goods [Policy Text Block]

Significant Accounting Policies

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, 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, upon product shipment or delivery to our customer or distributor as determined by agreed upon shipping terms. Shipping charges billed to customers are included in product sales and the related shipping costs are included in selling, general, and administrative expenses. 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 over a period of time as the performance obligation is satisfied over a period of time rather than a point in time. 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 recognize revenue over a period of time using costs incurred as the measurement of progress towards 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

September 

30,

2018

or

March 

31,

2018.

     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.
