DATA I/O CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

NOTE 1 - FINANCIAL STATEMENT PREPARATION

Data I/O prepared the financial statements as of March 31, 2010 and March 31, 2009 according to the rules and regulations of the Securities and Exchange Commission ("SEC"). These statements are unaudited but, in the opinion of management, include all adjustments (consisting of normal recurring adjustments and accruals) necessary to present fairly the results for the periods presented.  The balance sheet at December 31, 2009 has been derived from the audited financial statements at that date.  We have condensed or omitted certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America according to such SEC rules and regulations.  Operating results for the three months ended March 31, 2010 are not necessarily indicative of the results that may be expected for the year ending December 31, 2010. These financial statements should be read in conjunction with the annual audited financial statements and the accompanying notes included in the Company's Form 10-K for the year ended December 31, 2009.

Revenue Recognition

Data I/O recognizes revenue at the time of shipment. When arrangements include multiple elements, we use objective evidence of fair value to allocate revenue to the elements and recognize revenue when the criteria for revenue recognition have been met for each element. The amount of revenue recognized is affected by our judgments as to the collectability of the transaction or whether an arrangement includes multiple elements and if so, whether specific objective evidence of fair value exists for those elements.

The revenue related to products requiring installation that is perfunctory is recognized at the time of shipment provided that persuasive evidence of an arrangement exists, shipment has occurred, the price is fixed or determinable, and collectability is reasonably assured.  Installation that is considered perfunctory includes any installation that can be performed by other parties, such as distributors, other vendors, or in most cases the customers themselves. This takes into account the complexity, skill, and training needed as well as customer expectations regarding installation.  We measure the standalone fair value of the product versus the service installation value component by the amount paid to independent representative service groups or the amount of additional discount given to independent distributors to provide the service installation.

We record revenue from the sale of service and update contracts as deferred revenue and we recognize it on a straight-line basis over the contractual period, which is typically one year.  Service revenue from time and materials contracts and training services is recognized as services are performed.  We establish a reserve for sales returns based on historical trends in product returns and estimates for new items.  We have a stated return policy that customers can return standard products for any reason within 30 days after delivery, provided that the returned product is received in its original condition, including all packaging materials, for a refund of the price paid less a restocking charge of 30% of the total amount invoiced for the product returned, unless such restocking charge is waived in writing by Data I/O.

On those occasions where we sell software separately, we recognize software revenue upon shipment provided that no significant obligations remain on our part, substantive acceptance conditions, if any, have been met and when the fee is fixed and determinable and when collection is deemed probable.

Certain fixed-price engineering services contracts that require significant production, modification, or customization of software, are accounted for using the percentage-of-completion method.  We use the percentage-of-completion method of accounting because it is the most accurate method to recognize revenue based on the nature and scope of certain of our fixed-price engineering services contracts; it is a better measure of periodic income results than other methods and it better matches revenue recognized with the cost incurred.  Percentage of completion is measured based primarily on input measures such as hours incurred to date compared to total estimated hours to complete, with consideration given to output measures, such as contract milestones, when applicable.  Significant judgment is required when estimating total hours and progress to completion on these arrangements whi ch determines the amount of revenue we recognize as well as whether a loss is recognized if expected to be incurred upon project completion.  Revisions to hour and cost estimates are incorporated in the period the amounts are recognized if the results of the period have not been reported; otherwise, the revision of estimates are recognized in the period in which the facts that give rise to the revision become known.

Stock-Based Compensation Expense

Data I/O measures and recognizes compensation expense as required for all share-based payment awards, including employee stock options, stock awards, and employee stock purchases, based on estimated fair values on the grant dates. Total share-based compensation for the three months ended March 31, 2010 and March 31, 2009 was $75,000 and $94,000, respectively.

6

Income Tax

Historically when accounting for uncertainty in income taxes, Data I/O has not incurred any interest or penalties associated with tax matters and no interest or penalties were recognized during the three months ended March 31, 2010. However, the Company has adopted a policy whereby amounts related to interest and penalties associated with tax matters are classified as general and administrative expense when incurred.

Data I/O has incurred net operating losses in certain past years.  We continue to maintain a valuation allowance for the full amount of the net deferred tax asset balance associated with our net operating losses, as sufficient uncertainty exists regarding our ability to realize such tax assets in the future. There was $81,000 of unrecognized tax benefits related to uncertain tax positions as of March 31, 2010.

Tax years that remain open for examination include 2006, 2007, 2008 and 2009 in the United States of America. In addition, tax years from 1999 to 2005 may be subject to examination in the event that the Company utilizes the NOL’s or other carry forwards from those years in its current or future year tax return.

Recent Accounting Pronouncements

In February 2010, the Financial Accounting Standard Board (“FASB”) issued ASU No. 2010-09, Subsequent Events(Topic 855): Amendments to Certain Recognition and Disclosure Requirements ("ASU 2010-09"), which amends the disclosure guidance with respect to the disclosure of subsequent-events procedures. Specifically, the new guidance exempts SEC filers from disclosing the date through which subsequent events have been evaluated, instead requiring them to “evaluate subsequent events through the date the financial statements are issued.”  The impact of adoption of this standard had no financia l effect on the accompanying condensed consolidated financial statements.

In January 2010, theFASB issued ASU No. 2010-06, Fair Value Measurements and Disclosures(Topic 820): Improving Disclosures about Fair Value Measurements ("ASU 2010-06"), which amends the disclosure guidance with respect to fair value measurements. Specifically, the new guidance requires disclosure of amounts transferred in and out of Levels 1 and 2 fair value measurements, a reconciliation presented on a gross basis rather than a net basis of activity in Level 3 fair value measurements, greater disaggregation of the assets and liabilities for which fair value measurements are presented and more robust disclosure of t he valuation techniques and inputs used to measure Level 2 and 3 fair value measurements. ASU 2010-06 is effective for interim and annual reporting periods beginning after December 15, 2009, with the exception of the new guidance around the Level 3 activity reconciliations, which is effective for fiscal years beginning after December 15, 2010.  The impact of adoption of this standard had no financial effect on the accompanying condensed consolidated financial statements.

In October 2009, an update was made by FASB to revenue arrangements with multiple deliverables. It provides amendments to the criteria for separating consideration in multiple-deliverable arrangements. This standard establishes a selling price hierarchy for determining the selling price of a deliverable. The selling price used for each deliverable will be based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. This standard also replaces the term fair value in the revenue allocation guidance with se lling price to clarify that the allocation of revenue is based on entity-specific assumptions rather than assumptions of a market participant. It also eliminates the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangements to all deliverables using the relative selling price method. This standard will be effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Early adoption is permitted. We are currently assessing the potential impact that adoption of this standard may have on our consolidated financial statements.

In October 2009, an update was made by the FASB to software revenue recognition.According to this update, tangible products containing software components and non-software components that function together to deliver the tangible product’s essential functionality are no longer within the scope of the software revenue guidance. This standard requires that hardware components of a tangible product containing software components always be excluded from the software revenue guidance. It provides additional guidance on how to determine which software, if any, relating to the tangible product also would be excluded from the scope of the software revenue guidance. This standard will be effective prospectively for revenue arrangements entered into or materially modi fied in fiscal years beginning on or after June 15, 2010. Early adoption is permitted. This standard shall be adopted in the same period using the same transition method as indicated in the update to revenue arrangements with multiple deliverables. We are currently assessing the potential impact that adoption of this standard may have on our consolidated financial statements.

NOTE 8 – CONTINGENCIES

As of March 31, 2010, Data I/O was not a party to any legal proceedings, the adverse outcome of which in management’s opinion, individually or in the aggregate, would have a material adverse effect on our results of operations or financial position.

NOTE 9 – LONG-TERM DEBT

On September 27, 2006, the Company entered into a five year capital lease agreement in the amount of $591,145.  The imputed interest rate is 7.69%.  At March 31, 2010 scheduled maturities of the capital lease obligation for the years ending December 31 are as follows:

	Long-Term Debt
(in thousands)
2010	$                 106
2011	94
2012	-
Total minimum lease payments	$                 200

Current portion of long-term debt	(134)
Non-current portion of long-term debt	$                   57

NOTE 10 – EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per share is calculated based on the weighted average number of common shares outstanding during each period.  Diluted earnings per share is calculated based on these same weighted average shares outstanding plus the effect of potential shares issuable upon assumed exercise of stock options based on the treasury stock method.  Potential shares issuable upon the exercise of stock options are excluded from the calculation of diluted earnings per share to the extent their effect would be antidilutive.

The following table sets forth the computation of basic and diluted earnings per share:

	Three Months Ended
	March 31, 2010	March 31, 2009
(in thousands except per share data)
Numerator for basic and diluted earnings per share:
Net income (loss)	$                 709	$               (464)
Denominator for basic earnings per share -
weighted-average shares	8,959	8,876
Employee stock options and awards	121	-
Denominator for diluted earnings per share -
adjusted weighted-average shares and  assumed conversions of stock options	9,080	8,876
Basic and diluted earnings (loss) per share:
Total basic earnings (loss) per share	$                0.08	$              (0.05)
Total diluted earnings (loss) per share	$                0.08	$              (0.05)

The computation for the three months ended March 31, 2010 and March 31, 2009 excludes 151,437 and 793,738 options, respectively, to purchase common stock as their effect is antidilutive.

10

NOTE 11 – SHARE-BASED COMPENSATION

The impact on our results of operations of recording share-based compensation for the three months ended March 31, 2010 and March 31, 2009 are as follows:

	Three Months Ended
	March 31, 2010	March 31, 2009
(in thousands)
Cost of goods sold	$                     7	$                     7
Research and development	7	7
Selling, general and administrative	61	61
Total share-based compensation	$                   75	$                   75
Impact on net income (loss) per share:
Basic and diluted	$              (0.01)	$              (0.01)

The fair value of share-based awards for employee stock options was estimated using the Black-Scholes valuation model.  As no stock options were granted during the three months ended March 31, 2010 and March 31, 2009, there were no weighted average assumptions required to calculate fair value.

At March 31, 2010, there remained approximately $493,225 of unamortized expected future compensation expense associated with unvested option grants and restricted stock awards, with a remaining weighted average amortization period of 2.62 years.

NOTE 12 – COMPREHENSIVE INCOME (LOSS)

For the three months ended March 31, 2010 and March 31, 2009, total comprehensive income (loss) was comprised of the following:

	Three Months Ended
	March 31, 2010	March 31, 2009
(in thousands)
Net income (loss)	$                 709	$               (464)
Foreign currency translation gain (loss)	(98)	(124)
Total comprehensive income (loss)	$                 611	$               (588)

Item 2.Management's Discussion and Analysis of Financial Condition and Results of Operations

General

Forward-Looking Statements

This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.  This Act provides a “safe harbor” for forward-looking statements to encourage companies to provide prospective information about themselves as long as they identify these statements as forward-looking and provide meaningful cautionary statements identifying important factors that could cause actual results to differ from the projected results.  All statements other than statements of historical fact made in this Quarterly Report on Form 10-Q are forward-looking.  In particular, statements herein regarding industry prospects or trends; expected revenues; expected level of expense; future results of operations, restructuring implications; breakeven point, or financial position; changes in gross margin; economic conditions and capital spending outlook; market acceptance of our newly introduced or upgraded products; development, introduction and shipment of new products; and any other guidance on future periods are forward-looking statements.  Forward-looking statements reflect management’s current expectations and are inherently uncertain.  Although Data I/O believes that the expectations reflected in these forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance, achievements, or other future events.  Moreover, neither Data I/O nor anyone else assumes responsibility for the accuracy and completeness of these forward-looking statements.  Data I/O is under no duty to update any of these forward-looking statements after the date of this report.  The reader should not place undue reliance on these forward-looking statements.  The discussions above and in the section in Item 1A., Risk Factors “Cautionary Factors That May Affect Future Results ” in the Company’s Annual report on Form 10-K for the year ended December 31, 2009 describe some, but not all, of the factors that could cause these differences.

OVERVIEW

We continued to focus on our primary goal of managing the business to achieve profitable operations, while developing, launching and enhancing products to drive revenue and earnings growth.  Our challenge continues to be operating in a cyclical and challenging industry environment.  We are continuing our efforts to balance business geography shifts, increasing costs and strategic investments in our business with the level of demand and mix of business we expect.  Tempering these efforts is the current economic uncertainty regarding the recovery in certain geographic and customer segments. 

We are focusing our research and development efforts in our strategic growth markets, namely new programming technology, and automated programming systems for the manufacturing environment.  We continue to focus on extending the capabilities and support for our FlashCORE architecture, and the ProLINE-RoadRunner, FLX, PS, and FlashPAK product lines.  Our applications innovation strategy provides complete solutions to target customer’s business problems.  These solutions generally have a larger software element, may involve third-party components, and in many cases, will be developed or customized to address the specific requirements of individual customers.  During the first quarter of 2010 we received two major software application orders.  We believe by adding these features and applications to our strategic product platforms, we will be able to set ourselves apar t from other product suppliers and elevate our relationships with our customers to a partner level. 

Our customer focus has been on strategic high volume manufacturers in key market segments like wireless, automotive, industrial controls and programming centers and supporting NAND Flash and microcontrollers on our newer products to gain new accounts and in newer areas, such as microcontrollers for the automotive market with our new ProLINE-RoadRunner XLF.  We have continued to expand our China operations to take advantage of the growth of manufacturing in China and to operate close to our customers.  We have continued to address the effectiveness of our sales and marketing organization and sales channels by adding and changing channels during 2009 and 2010.  We recognized the need to diversify our customer base and are continuing to take steps to broaden our channels of distribution and representation to reach a greater number of customers.  During 2009 we broadened our sal es coverage in the Americas and have added, and trained, additional sales representative channels, again expanding the use of a variable cost model.

BUSINESSRESTRUCTURING

We took actions in 2008 totaling $542,000, primarily severance-related, and additional actions in 2009 totaling $203,000 to flatten and streamline the organization, as well as reducing cost, by decreasing the size of our Board and abandoning a portion of our building space.  At March 31, 2010, $133,000 remains accrued and will be fully paid out during 2010 and 2011.

cRITICAL aCCOUNTING pOLICY jUDGMENTS AND eSTIMATES

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires that we make estimates and judgments, which affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities.  On an on-going basis, Data I/O evaluates our estimates, including those related to revenue recognition, estimating the percentage-of-completion on fixed-price professional engineering service contracts, sales returns, bad debts, inventories, investments, intangible assets, income taxes, warranty obligations, restructuring charges, contingencies such as litigation, and contract terms that have multiple elements and other complexities typical in the capital equipment industry.  We base our estimates on historical experience and other assumptions that we believe are reas onable under the circumstances.  Actual results may differ from these estimates under different assumptions or conditions. 

Data I/O believes the following critical accounting policies affect the more significant judgments and estimates used in the preparation of our financial statements:

Revenue Recognition:  Sales of Data I/O’s semiconductor programming equipment are recognized at the time of shipment.  We have determined that our automated products have reached a point of maturity and stability such that product acceptance can be assured by testing at the factory prior to shipment and that the installation meets the criteria to be considered a separate element.  These systems are standard products with published product specifications and are configurable with standard options.  The evidence that these systems could be accepted was based upon having standardized factory production of the units, results from batteries of tests of product performance to our published specifications, quality inspections and installation standardization, as well as past product operation validation with customers and the history provided by our installed base of products upon which the current versions were based.   When arrangements include multiple elements, we use objective evidence of fair value to allocate revenue to the various elements and recognize revenue when the criteria for revenue recognition have been met for each element.  The amount of revenue recognized is affected by our judgments as to the collectability of the transaction or whether an arrangement includes multiple elements and if so, whether specific objective evidence of fair value exists for those elements.  The measure of standalone fair value of the product versus the service installation value component is determined by the amount Data I/O pays to independent representative service groups or the amount of additional discount given to independent distributors, to provide the service installation.  Changes to the elements in an arrangement and the ability to establish specific objective evidence for those elements could affect the timing of the revenue recognition.  These conditions could be subjective and actual results could vary from the estimated outcome. 

Installation that is considered perfunctory includes any installation that can be performed by other parties, such as distributors, other vendors, or in most cases the customer themselves.  This takes into account the complexity, skill, and training needed as well as customer expectations regarding installation.  The revenue related to products requiring installation that is perfunctory is recognized at the time of shipment provided that persuasive evidence of an arrangement exists, shipment has occurred, the price is fixed or determinable, and collectability is reasonably assured.

We record revenue from the sale of service and update contracts as deferred revenue and we recognize it on a straight-line basis over the contractual period, which is typically one year.  Service revenue from time and materials contracts and training services is recognized as services are performed.  We establish a reserve for sales returns based on historical trends in product returns and estimates for new items.  We have a stated return policy that customers can return standard products for any reason within 30 days after delivery, provided that the returned product is received in its original condition, including all packaging materials, for a refund of the price paid less a restocking charge of 30% of the total amount invoiced for the product returned, unless such restocking charge is waived in writing by Data I/O.

We recognize software revenue upon shipment provided that no significant obligations remain on our part, substantive acceptance conditions, if any, have been met and when the fee is fixed and determinable and when collection is deemed probable.

Certain fixed-price engineering service contracts that require significant production, modification, or customization of software, are accounted for using the percentage-of-completion method.  We use the percentage-of-completion method of accounting because it is the most accurate method to recognize revenue based on the nature and scope of our fixed-price professional engineering service contracts; it is a better measure of periodic income results than other methods and it better matches revenue recognized with the costs incurred.  Percentage of completion is measured based primarily on input measures such as hours incurred to date compared to total estimated hours to complete, with consideration given to output measures, such as contract milestones, when applicable.  Significant judgment is required when estimating total hours and progress to completion on these arrangements wh ich determines the amount of revenue we recognize as well as whether a loss is recognized if one is expected to be incurred upon project completion.  Revisions to hour and cost estimates are incorporated in the period the amounts are recognized if the results of the period have not been reported; otherwise, the revision of estimates are recognized in the period in which the facts that give rise to the revision become known.

13

We establish a reserve for sales returns based on historical trends in product returns and estimates for new items.  Data I/O has a stated return policy that customers can return standard products for any reason within 30 days after delivery provided that the returned product is received in its original condition, including all packaging materials, for a refund of the price paid less a restocking charge of 30% of the total amount invoiced for the product returned, unless such restocking charge is waived in writing by Data I/O.  For us to recognize revenue, the price is fixed or determinable at the date of the sale, the buyer has paid or is obligated to pay and the obligation is not contingent on resale of the product, the buyer’s obligation would not be changed in the event of theft, physical destruction or damage to the product, the buyer acquiring the product for resale has eco nomic substance apart from Data I/O and we have  no contractual obligations for future performance to directly bring about the resale of the product by the buyer. 

Allowance for Doubtful Accounts: We base the allowance for doubtful accounts receivable on our assessment of the collectability of specific customer accounts and the aging of accounts receivable.  If there is deterioration of a major customer’s credit worthiness or actual defaults are higher than historical experience, our estimates of the recoverability of amounts due to us could be adversely affected. 

Inventory: Inventories are stated at the lower of cost or market.  Adjustments are made to standard cost, which approximates cost on a first-in, first-out basis.  We estimate reductions to inventory for obsolete, slow-moving, excess and non-salable inventory by reviewing current transactions and forecasted product demand.  We evaluate our inventories on an item by item basis and record inventory adjustments accordingly.  If there is a significant decrease in demand for our products or there is a higher risk of inventory obsolescence because of rapidly changing technology and customer requirements, Data I/O may be required to increase our inventory adjustments and our gross margin could be adversely affected. 

Warranty Accruals: Data I/O accrues for warranty costs based on the expected material and labor costs to fulfill our warranty obligations.  If we experience an increase in warranty claims, which are higher than our historical experience, our gross margin could be adversely affected. 

Tax Valuation Allowances:  Given the uncertainty created by our loss history, as well as the current uncertain economic outlook for our industry and capital spending, Data I/O expects to continue to limit the recognition of net deferred tax assets and accounting for uncertain tax positions and maintain the tax valuation allowances.  We expect, therefore, that reversals of the tax valuation allowance will take place only as we are able to take advantage of the underlying tax loss or other attributes in carry forward.  The transfer pricing and expense or cost sharing arrangements are complex areas where judgments, such as the determination of arms-length arrangements, can be subject to challenges by different tax jurisdictions. 

Share-based Compensation:  We accounted for share-based awards made to our employees and directors, including employee stock option awards and restricted and performance share awards, using the estimated grant date fair value method of accounting.  We estimate the fair value using the Black-Scholes valuation model, which requires the input of highly subjective assumptions, including the option’s expected life and the price volatility of the underlying stock.  The expected stock price volatility assumption was determined using the historical volatility of the Company’s common stock.  Changes in the subjective assumptions required in the valuation model may significantly affect the estimated value of the awards, the related stock-based compensation expense and, consequently, our results of operations.  Beginning in the second quarter of 2006, restricted stock awards were granted.  Employee Stock Purchase Plan (“ESPP) shares were issued under provisions that do not require us to record any equity compensation expense.

Revenue increased $1.9 million or 42.6% for the first quarter of 2010 compared to the first quarter of 2009.  We experienced increased sales in all geographies and in each of our major product lines, led by automated system sales of $4.2 million, up over 50% from the first quarter of 2009.  Revenues also benefited from the introduction of our new FlashCORE III technology into all of our major product lines, as customers sought a better solution to cope with the increasing use of very high-density Flash memory.  In the last few months, our FlashCORE III technology received industry awards in all three geographic regions.  The backlog of orders totaled $1.1 million at the end of the first quarter of 2010, a decrease compared to the backlog at March 31, 2009 of $1.2 million.  This decrease was partially due to a shift to deferred revenue of $290,000, which we expect to recognize as revenue over the next two quarters.

International	5,586	42.6%	3,918
% of total	89.3%		89.4%

Our trend in orders booked showed significant growth over the first quarter of 2009 in all geographies.  Orders from Asian customers were up 136% from the mix, with orders in the Americas up 68% and orders in Europe up 46%.  At the start of the second quarter, we are seeing progressively stronger worldwide sales funnels. We expect our new products including FlashCORE III to provide revenue growth and expect revenues from our new sales channels will continue to grow as they gain additional training and experience with our product lines.

Gross Margin

	Three Months Ended
	March 31, 2010	Change	March 31, 2009
(in thousands)
Gross margin	$     3,753	53.6%	$     2,443
Percentage of net sales	60.0%		55.7%

Gross margins during the first quarter of 2010 increased in both dollars and as a percentage of sales compared to the first quarter of 2009.  Gross margin as a percentage of sales for the first quarter improved to 60%, a 4.3 percentage point increase over the first quarter of 2009.  The improvement was primarily due to the higher first quarter sales volume relative to fixed factory costs, as well as a more favorable mix of price and product mix, especially from additional software revenues.  Factory variances were relatively low for both the first quarter of 2010 and 2009.  However, our continued inventory reductions resulted in less labor and overhead absorption, contributing to an unfavorable labor and overhead application variance of $76,000 for the first quarter of 2010.

Research and Development

Research and development	$         950	(8.0%)	$      1,033
Percentage of net sales	15.2%		23.6%

Research and development (“R&D”) spending for the first quarter of 2010 decreased by approximately $83,000 compared to the first quarter of 2009.  R&D as a percentage of net sales also decreased, primarily due to the increase in sales for the first quarter of 2010, as well as reclaiming as inventory $60,000 of previously expensed R&D project materials and a $32,000 charge to operations for engineer labor.  New products include enhancements to FlashCORE III, our new programming architecture, and the new versions of ProLINE RoadRunner for Siemens and MyData placement machines.

Percentage of net sales	31.0%		38.2%

Selling, general and administrative (“SG&A”) expenses increased approximately $262,000 for the first quarter of 2010 compared to the first quarter of 2009.  This was due primarily to approximately $170,000 higher commission expense due to the higher sales volume and $69,000 higher incentive compensation expense in the first quarter of 2010 compared to the first quarter of 2009.

Interest expense	$            (3)	(50.0%)	$            (6)

Interest income decreased during the first quarter of 2010 compared to the same period in 2009 due to the lower yields on investments despite the higher cash balances.  Interest expense decreased in the first quarter of 2010 compared to the same period in 2009 due to the lower balance on the equipment capital lease.

Income tax (expense) benefit	$        (102)	(20.3%)	$        (128)

Income tax expense recorded for the first quarter of 2010 and 2009 resulted from foreign and state taxes.  The effective tax rate differed from the statutory tax rate primarily due to the effect of valuation allowances and state taxes.  Data I/O has a valuation allowance of $9,244,000 as of March 31, 2010.  Our deferred tax assets and valuation allowance are reduced by approximately $81,000 associated with the requirements of accounting for uncertain tax positions as of March 31, 2010.

Working capital	$    19,456	$             720	$    18,736

At March 31, 2010, Data I/O’s principal sources of liquidity consisted of existing cash and cash equivalents which continued to increase during the quarter.  Our working capital increased by $720,000 from December 31, 2009,  However, our current ratio decreased from 5.2 at December 31, 2009 to 4.9 at March 31, 2010.

Our cash and cash equivalents increased by approximately $42,000 during the three months ended March 31, 2010 primarily due to net income for the quarter, continued inventory reductions, increased accounts payable and deferred revenue, offset by increased accounts receivable and capital equipment additions.  

16

We expect that we will continue to make capital expenditures to support our business.  Capital expenditures are expected to be funded by existing and internally generated funds or lease financing.   

As a result of our significant product development, customer support, international expansion and selling and marketing efforts, we have required substantial working capital to fund our operations.  Over the last few years, we restructured our operations to lower our costs and operating expenditures in some geographic regions, while investing in other regions, and to lower the level of revenue required for our net income breakeven point, to preserve our cash position and to focus on profitable operations.  We believe that we have sufficient working capital available under our operating plan to fund our operations and capital requirements through at least the next one-year period.  Our working capital may be used to fund growth initiatives including acquisitions which could reduce our liquidity.  Any substantial inability to achieve our current business plan could have a mate rial adverse impact on our financial position, liquidity, or results of operations and may require us to reduce expenditures and/or seek additional financing.

Long-term debt	$       57	$     (33)	$           90

During the third quarter of 2006, the Company entered into a five-year capital lease agreement in the amount of $591,145.  The lease was used to fund new equipment and installation associated with our move to the new facility in July of 2006.  See Note 9, “Long-Term Debt.”

OFF-Balance sheet arrangements

Except as noted above in Note 7, “Operating Lease and Other Commitments,” Data I/O had no off-balance sheet arrangements.

RECENT ACCOUNTING PRONOUNCEMENTS

In February 2010, the Financial Accounting Standard Board (“FASB”) issued ASU No. 2010-09, Subsequent Events(Topic 855): Amendments to Certain Recognition and Disclosure Requirements ("ASU 2010-09"), which amends the disclosure guidance with respect to the disclosure of subsequent-events procedures. Specifically, the new guidance exempts SEC filers from disclosing the date through which subsequent events have been evaluated, instead requiring them to “evaluate subsequent events through the date the financial statements are issued.”  The impact of adoption of this standard had no financia l effect on the accompanying condensed consolidated financial statements.

In January 2010, the FASB issued ASU No. 2010-06, Fair Value Measurements and Disclosures(Topic 820): Improving Disclosures about Fair Value Measurements ("ASU 2010-06"), which amends the disclosure guidance with respect to fair value measurements. Specifically, the new guidance requires disclosure of amounts transferred in and out of Levels 1 and 2 fair value measurements, a reconciliation presented on a gross basis rather than a net basis of activity in Level 3 fair value measurements, greater disaggregation of the assets and liabilities for which fair value measurements are presented and more robust disclosure of the valuation techniques and inputs used to measure Level 2 and 3 fair value measurements. ASU 2010-06 is effective for interim and annual reporting periods beginning after December 15, 2009, with the exception of the new guidance around the Level 3 activity reconciliations, which is effective for fiscal years beginning after December 15, 2010.  The impact of adoption of this standard had no financial effect on the accompanying condensed consolidated financial statements.

In October 2009, an update was made by FASB to revenue arrangements with multiple deliverables. It provides amendments to the criteria for separating consideration in multiple-deliverable arrangements. This standard establishes a selling price hierarchy for determining the selling price of a deliverable. The selling price used for each deliverable will be based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. This standard also replaces the term fair value in the revenue allocation guidance with se lling price to clarify that the allocation of revenue is based on entity-specific assumptions rather than assumptions of a market participant. It also eliminates the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangements to all deliverables using the relative selling price method. This standard will be effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Early adoption is permitted. We are currently assessing the potential impact that adoption of this standard may have on our consolidated financial statements.

17

In October 2009, an update was made by the FASB to software revenue recognition.According to this update, tangible products containing software components and non-software components that function together to deliver the tangible product’s essential functionality are no longer within the scope of the software revenue guidance. This standard requires that hardware components of a tangible product containing software components always be excluded from the software revenue guidance. It provides additional guidance on how to determine which software, if any, relating to the tangible product also would be excluded from the scope of the software revenue guidance. This standard will be effective prospectively for revenue arrangements entered into or materially modi fied in fiscal years beginning on or after June 15, 2010. Early adoption is permitted. This standard shall be adopted in the same period using the same transition method as indicated in the update to revenue arrangements with multiple deliverables. We are currently assessing the potential impact that adoption of this standard may have on our consolidated financial statements.

Not applicable.

Item 4.  Controls and Procedures

Evaluation of disclosure controls and procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, Data I/O evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act) as of the end of the period covered by this report (the “Evaluation Date”). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the Evaluation Date, our disclosure controls and procedures were effective at the reasonable level of assurance. Disclosure Controls are controls and procedures designed to reasonably assure that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Discl osure Controls are also designed to reasonably assure that such information is accumulated and communicated to our management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Changes in internal controls

There were no changes made in our internal controls during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
