NOTE 2.  - STOCK-BASED COMPENSATION

Stock Options: During the six months ended June 30, 2012, the Company issued 136,000 stock options that vest over a one to four year period and expire ten years from date of grant.  The weighted average exercise price of these stock options is $5.27.  During the six months ended June 30, 2011, the Company issued 215,000 stock options that vest over a three to four year period and expire ten years from the date of grant. The weighted average exercise price of these stock options is $2.00.  Compensation expense related to these stock options was $104,000 and $46,000 for the three months ended June 30, 2012 and 2011, respectively.  Compensation expense related to these stock options was $177,000 and $71,000 for the six months ended June 30, 2012 and 2011, respectively.

During the six months ended June 30, 2012, the Company also issued 448,000 stock options with performance-based vesting conditions for the years ending December 31, 2012, 2013, 2014, and 2015, the achievement of which would result in pro rata vesting per year in February 2013, 2014, 2015, and 2016, respectively. The weighted average exercise price of these stock options is $4.76.  During the six months ended June 30, 2011, the Company issued 10,000 stock options with performance-based vesting conditions related to non-financial objectives for November 2011 and January 2012 and revenue objectives for the years ending December 31, 2012, 2013 and 2014, the achievement of which would result in vesting per year in February 2013, 2014 and 2015.  All stock options with performance-based conditions expire ten years from date of grant.  Of the stock options outstanding at June 30, 2012, 680,300 are subject to the achievement of certain performance conditions.  The performance conditions related to approximately 27,000 of these stock options were deemed probable as of June 30, 2012.  Compensation expense related to performance-based stock options, for which vesting was deemed probable, was $40,000 and $4,000 for the three months ended June 30, 2012 and 2011, respectively.  Compensation expense related to performance-based stock options, for which vesting was deemed probable, was $85,000 and $15,000 for the six months ended June 30, 2012 and 2011, respectively.  The performance conditions related to the remaining options were not deemed probable at June 30, 2012; therefore no compensation expense related to these options has been recorded.

The weighted-average remaining contractual life of stock options outstanding and exercisable at June 30, 2012 and 2011 is 3.28 years and 1.65 years, respectively.

Restricted Stock: The Interphase Corporation 2004 Long-Term Stock Incentive Plan provides for grants of bonus stock awards (“restricted stock”) to its directors and certain employees at no cost to the recipient.  Holders of restricted stock are entitled to cash dividends, if declared, and to vote their respective shares.  Restrictions limit the sale or transfer of these shares during a predefined vesting period, currently ranging from three to six years, and in some cases vesting is subject to the achievement of certain performance conditions. During the six months ended June 30, 2012, the Company issued 9,000 shares of restricted stock.  During the six months ended June 30, 2011, the Company issued 72,000 shares of restricted stock.  Upon issuance of restricted stock under the plan, unearned compensation equivalent to the market value at the date of grant is recorded as a reduction to shareholders’ equity and subsequently amortized to expense over the respective restriction periods.  Compensation expense related to restricted stock was $36,000 and $50,000 for the three months ended June 30, 2012 and 2011, respectively.  Compensation expense related to restricted stock was $69,000 and $106,000 for the six months ended June 30, 2012 and 2011, respectively.  As of June 30, 2012, there was $330,000 of total unamortized compensation cost related to unvested restricted stock remaining to be recognized. The expense is expected to be recognized over a weighted-average period of 2.5 years.  As of December 31, 2011, there was $479,000 of total unamortized compensation cost related to unvested restricted stock which was expected to be recognized over a weighted-average period of 3.0 years.  The following table summarizes the restricted stock activity for the six months ended June 30, 2012:

NOTE 3.  -  MARKETABLE SECURITIES

Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in accordance with accounting principles generally accepted in the United States, and expands disclosures about fair value measurements.  The Company follows ASC 820 in its valuation of its marketable securities.  ASC 820 defines fair value as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 classifies the levels used to measure fair value into the following hierarchy:

Level 1 – Valuations based on quoted prices in active markets for identical assets and liabilities that the reporting entity has the ability to obtain at the measurement date.  This level provides the most reliable evidence of fair value.

Level 2 – Valuations based on one or more quoted prices in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs that are observable other than quoted prices for the asset or the liability; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

The Company’s investments in marketable securities primarily consist of investments in debt securities, which are classified as available for sale and presented as current assets on the accompanying condensed consolidated balance sheets. Earnings from debt securities are calculated on a yield to maturity basis and recorded in the results of operations. Unrealized gains or losses for the periods presented were included in other comprehensive income (loss). Realized gains and losses are computed based on the specific identification method and were not material for the periods presented. Marketable securities are used to secure the Company’s credit facility.  The fair values of marketable securities were estimated using the market approach.

Financial assets, measured at fair value, by level within the fair value hierarchy were as follows (in thousands):

		June 30, 2012						December 31, 2011
	Fair Value Hierarchy	Cost		Unrealized Gain		Estimated Fair Value		Cost		Unrealized Gain		Estimated Fair Value

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Valuing inventory at the lower of cost or market involves an inherent level of risk and uncertainty due to technology trends in the industry and customer demand for the Company’s products.  Future events may cause significant fluctuations in the Company’s operating results.  Inventories are written down when needed to ensure the Company carries inventory at the lower of cost or market.  The Company decreased reserve requirements by $5,000 during the three months ended June 30, 2012.  There were no writedowns during the three months ended June 30, 2011.  Writedowns during the six months ended June 30, 2012 were $20,000.  There were no writedowns during the six months ended June 30, 2011.  

NOTE 5.  -  INCOME TAXES

The Company records a valuation allowance when it is “more likely than not” that all or a portion of a deferred tax asset will not be realized.  Management reviews all available positive and negative evidence, including the Company’s current and past performance, the market environment in which the Company operates, the utilization of past tax credits, length of carry back and carry forward periods, existing contracts or sales backlog that will result in future profits, as well as other factors.  The Company continues to maintain a valuation allowance on all of the net deferred tax assets for the periods presented.  Until an appropriate level of profitability is sustained, the Company expects to continue to record a full valuation allowance on future tax benefits except for those that may be generated in foreign jurisdictions.  The effective income tax rates for the periods presented differ from the U.S. statutory rate as the Company continues to provide a full valuation allowance for the net deferred tax assets at June 30, 2012 and 2011.

NOTE 6.  -  RESTRUCTURING CHARGE

On September 30, 2010, the Company initiated a restructuring plan to mitigate gross margin erosion by reducing manufacturing and procurement costs, streamline research and development expense and focus remaining resources on key strategic growth areas, and reduce selling and administrative expenses through product rationalization and consolidation of support functions.  Under the 2010 restructuring plan, the Company reduced its worldwide work force by 39 employees, including the closure of its European engineering and support center located in Chaville, France.  As a result of the 2010 restructuring plan, the Company recorded a restructuring charge of approximately $3.3 million, classified as an operating expense, in the third quarter of 2010 related to future cash expenditures to cover employee severance and benefits and other related costs.  Cash payments, net of currency translation adjustments, during the three and six months ended June 30, 2011 were approximately $141,000 and $1.2 million, respectively.  The remaining liability as of June 30, 2011 was $29,000.  These amounts were paid out under the restructuring plan by the end of 2011.

NOTE 7.  -  CREDIT FACILITY

The Company maintains a $5.0 million revolving bank credit facility maturing December 19, 2013.  The applicable interest rate on outstanding balances is LIBOR plus 1.0% to 1.5% based on certain factors included in the credit agreement.  At June 30, 2012 and December 31, 2011, the Company’s interest rate on the $3.5 million outstanding balance was 2.0% and 1.8%, respectively. The unused portion of the credit facility is subject to an unused facility fee ranging from .25% to .75% depending on total deposits with the creditor.  All borrowings under this facility are secured by marketable securities.  The outstanding balance of $3.5 million as of June 30, 2012 and December 31, 2011 is classified as long-term debt on the Company’s condensed consolidated balance sheets.  Subsequent to June 30, 2012 and prior to the Company’s filing of the condensed consolidated financial statements, the outstanding balance on the credit facility was repaid.

The Board of Directors adopted a Shareholder Rights Plan (the “Plan”) and, under the Plan, declared a non-taxable dividend, paid at the close of business on August 9, 2011 (the “Record Date”), of one common share purchase right (a “Right”) for each outstanding share of Common Stock.  From the Record Date until the Rights become exercisable, the Rights will be attached to all outstanding shares of Common Stock and, therefore, will be represented by the certificates evidencing the shares of Common Stock and transferrable only with the shares of Common Stock.  A Right will be exercisable, upon certain conditions, to purchase one share of Common Stock from the Company at a price of $39, subject to adjustment.  The Rights will become exercisable, and separate from the shares of Common Stock, upon the earlier of:

(1)  ten business days following the date of the first public announcement (the “Stock Acquisition Date”) that a person or a group of affiliated or associated persons has acquired, or obtained the right to acquire, beneficial ownership of 15% or more of the outstanding shares of Common Stock (an “Acquiring Person”), or

(2)  ten business days (or such later date as the Board of Directors may determine) following the commencement of a tender or exchange offer that, if consummated, would result in a person or group of persons becoming an Acquiring Person.

Upon a Stock Acquisition Date, each holder of a Right (other than an Acquiring Person) will be entitled to receive, upon exercise of the Right, shares of Common Stock at a 50% discount.  Also, if, at any time following a Stock Acquisition Date, the Company is acquired in a merger or business combination and its Common Stock is exchanged or converted, or if 50% or more of the Company’s assets, cash flow or earning power is sold or transferred, then each holder of a Right (other than an Acquiring Person) will be entitled to receive, upon exercise of the Right, shares of the acquirer’s common stock at a 50% discount.  Further, at any time after a person or group of persons becomes an Acquiring Person, but before any person or group of persons becomes the beneficial owner of 50% or more of the outstanding shares of Common Stock, the Company may cause each exercisable Right to be exchanged for one share of Common Stock.  The Rights will expire at the close of business on July 29, 2021, or such other date as the Board of Directors may determine under certain circumstances.  The Board of Directors may terminate the Plan or cause the Company to redeem the Rights, at a price of $0.001 per Right, at any time before the earlier of a Stock Acquisition Date or the expiration of the Rights.  The Company has reserved 90,315,210 shares of Common Stock for possible issuance upon exercise of Rights under the Plan.

RESULTS OF OPERATIONS

Revenue

Total revenue decreased 44% to $3.5 million for the three months ended June 30, 2012, compared to $6.2 million for the same period in the prior year.  Our telecommunications product revenue decreased to $2.6 million for the three months ended June 30, 2012, compared to $5.3 million in the comparable period in the prior year.  This decrease was primarily driven by two factors.  First, the slowdown in telecommunications equipment spending worldwide, including Europe and the Pacific Rim, has had a negative impact on our major customers and has impacted their purchase volume from us.  Second, we experienced significantly reduced sales of an interworking product where the primary customer has delayed, until the second half of 2012, the launch of its product.  Our services revenues increased to $708,000 for the three months ended June 30, 2012, compared to $519,000 for the same period in the previous year, because of increases in electronic manufacturing services and, to a lesser degree, increases in electronic engineering design services.  As expected, our enterprise product revenue decreased to $85,000 for the three months ended June 30, 2012 compared to $361,000 for the same period in the previous year because the major customer roll-out driving this product line has been completed.  All other revenues decreased to $28,000, compared to $41,000 in the comparable period last year.

Total revenue decreased 42% to $7.5 million for the six months ended June 30, 2012, compared to $12.9 million for the same period in the prior year.  Our telecommunications product revenue decreased to $5.8 million for the six months ended June 30, 2012, compared to $10.7 million in the comparable period in the prior year.  This decrease was primarily driven by two factors.  First, the slowdown in telecommunications equipment spending worldwide, including Europe and the Pacific Rim, has had a negative impact on our major customers and has impacted their purchase volume from us.  Second, we experienced significantly reduced sales of an interworking product where the primary customer has delayed, until the second half of 2012, the launch of its product.  Our services revenues increased to $1.5 million for the six months ended June 30, 2012, compared to $884,000 for the same period in the previous year, because of increases in electronic engineering design services and, to a lesser degree, increases in electronic contract manufacturing services.  As expected, our enterprise product revenue decreased to $188,000 for the six months ended June 30, 2012 compared to $1.2 million for the same period in the previous year because the major customer roll-out driving this product line has been completed.  All other revenues decreased to $51,000, compared to $65,000 in the comparable period last year.

If telecommunications revenues continue at these levels, we will work to improve our execution and financial performance and to align our cost structure with this revenue and margin profile.  All efforts will be designed to enable us to invest in our business to respond to industry shifts and capitalize on emerging opportunities and to better serve our customers and partners in both the short- and long-term.

13

During the second quarter of 2012, sales to three customers individually accounted for approximately 29%, 17%, and 12% of total revenues, respectively.  During the second quarter of 2011, sales to two customers individually accounted for approximately 27% and 20% of total revenues, respectively.  No other customers individually accounted for more than 10% of our consolidated revenues in the periods presented.

Included in accounts receivable at June 30, 2012 was $944,000, $566,000, and $339,000 due from Alcatel-Lucent, Samsung, and Nokia Siemens Networks, respectively.  Included in accounts receivable at December 31, 2011 was $786,000 and $734,000, due from Alcatel-Lucent and Nokia Siemens Networks, respectively.  No other customers individually accounted for more than 10% of our accounts receivable in the periods presented.

Gross Margin

Gross margin as a percentage of revenue was 45% and 53% for the three months ended June 30, 2012 and 2011, respectively.  The decrease in gross margin percentage in the second quarter of 2012 compared to the same period in the prior year was primarily due to decreased utilization of our manufacturing facility, partially offset by a shift in product mix toward higher margin products.

Gross margin as a percentage of revenue was 46% and 51% for the six months ended June 30, 2012 and 2011, respectively.  The decrease in gross margin was primarily due to decreased utilization of our manufacturing facility, partially offset by a shift in product mix toward higher margin products.

We believe that pricing pressures in the industry and our anticipated future product mix may further reduce our gross margin percentage in future periods.

Research and Development

Our investment in research and development was $854,000 and $1.0 million for the three months ended June 30, 2012 and 2011, respectively.  During the quarter, there was an increase in professional services activity, which resulted in an increase in services revenues.  Engineering costs associated with these activities generate revenue; as such, the related expenses are recorded as cost of sales rather than research and development operating expenses thus causing the primary decrease in research and development expenses during the quarter.  As a percentage of revenue, research and development expenses were approximately 25% in the second quarter of 2012 compared to approximately 16% for the same period in the prior year.  The increase in research and development expenses as a percentage of total revenue was due to revenue decreasing at a higher rate than research and development expenses.

Our investment in research and development was $1.8 million and $2.0 million for the six months ended June 30, 2012 and 2011, respectively.  During the first six months of 2012, there was an increase in professional services activity, which resulted in an increase in services revenues.  Engineering costs associated with these activities generate revenue; as such, the related expenses are recorded as cost of sales rather than research and development operating expenses thus causing the primary decrease in research and development expenses during the this period.  As a percentage of revenue, research and development expenses were approximately 24% for the six months ended June 30, 2012 compared to approximately 16% for the same period in the prior year.  The increase in research and development expenses as a percentage of total revenue was due to revenue decreasing at a higher rate than research and development expenses.  We will continue to monitor the level of our investments in research and development concurrently with actual revenue results.

Sales and Marketing

Sales and marketing expenses were $1.1 million and $872,000 for the three months ended June 30, 2012 and 2011, respectively. The increase in sales and marketing expense was primarily due to an increase in marketing, public relations and tradeshow activities related to the introduction of our new product, penveu™.  As a percentage of revenue, sales and marketing expenses were approximately 33% for the second quarter of 2012, compared to approximately 14% for the same period in the prior year.  The increase in sales and marketing expenses as a percentage of total revenue was due to sales and marketing expenses increasing while revenue decreased.

14

Sales and marketing expenses were $2.0 million and $1.9 million for the six months ended June 30, 2012 and 2011, respectively. The increase in sales and marketing expense was primarily due to an increase in marketing, public relations and tradeshow activities related to the introduction of our new product, penveu™, partially offset by a decrease in variable compensation attributable to lower revenue year over year.  As a percentage of revenue, sales and marketing expenses were approximately 27% for the six months ended June 30, 2012, compared to approximately 15% for the same period in the prior year.  The increase in sales and marketing expenses as a percentage of total revenue was due to sales and marketing expenses increasing while revenue decreased.  We will continue to monitor the level of sales and marketing costs concurrently with actual revenue results.

General and Administrative

General and administrative expenses were $731,000 and $1.0 million for the three months ended June 30, 2012 and 2011, respectively.  The decrease in general and administrative expenses was primarily due to a decrease in legal services expense of $170,000 and a decrease in variable compensation expense of $95,000.  As a percentage of revenue, general and administrative expenses were approximately 21% in the second quarter 2012 and 17% for the same period in the prior year.  The increase in general and administrative expenses as a percentage of total revenue was due to revenue decreasing at a higher rate than general and administrative expenses.

General and administrative expenses were $1.7 million and $2.0 million for the six months ended June 30, 2012 and 2011, respectively.  The decrease in general and administrative expenses was primarily due to a decrease in variable compensation expense of $180,000 and a decrease in legal services expense of $70,000.  As a percentage of revenue, general and administrative expenses were approximately 22% for the six months ended June 30, 2012 and 16% for the same period in the prior year.  The increase in general and administrative expenses as a percentage of total revenue was due to revenue decreasing at a higher rate than general and administrative expenses.  We will continue to monitor the level of general and administrative costs concurrently with actual revenue results.

Interest Income, Net

Interest income, net of interest expense, decreased to $6,000 for the three months ended June 30, 2012 from $8,000 in the comparable period in the prior year.  Interest income, net of interest expense, increased to $15,000 for the six months ended June 30, 2012 from $11,000 in the comparable period in the prior year.

Other Income (Loss), Net

Other income, net was $3,000 for the three months ended June 30, 2012.  Other loss, net was $6,000 for the three months ended June 30, 2011.  Other loss, net was $2,000 and $1,000 for the six months ended June 30, 2012 and 2011, respectively.

Income Taxes

Our tax benefit rate was 0.4% for the six months ended June 30, 2012, compared to a tax expense rate of 4.0% for the six months ended June 30, 2011.  The effective income tax rates for the periods presented differ from the U.S. statutory rate as we continue to provide a full valuation allowance for our net deferred tax assets at June 30, 2012 and June 30, 2011.  The tax benefit and tax expense in the periods presented primarily relates to tax in a foreign jurisdiction.

Net (Loss) Income

We reported a net loss of $1.1 million for the three months ended June 30, 2012 and a net income of $317,000 for the three months ended June 30, 2011.  Basic loss per share for the three months ended June 30, 2012 was ($0.16).  Basic earnings per share for the three months ended June 30, 2011 was $0.05.  Diluted earnings per share for the three months ended June 30, 2011 was $0.04.  We reported a net loss of $2.1 million for the six months ended June 30, 2012 and a net income of $548,000 for the six months ended June 30, 2011.  Basic loss per share for the six months ended June 30, 2012 was ($0.30).  Basic and diluted earnings per share for the six months ended June 30, 2011 was $0.08.

Recently Announced Product

On April 18, 2012 we announced the debut of penveuTM.  penveu is a handheld device that enhances the functionality of installed projectors and large screen displays; making any flat surface, from pull down screens to HDTVs, an interactive display system.  Using embedded computer vision technology, penveu works with any device with a VGA connection and requires no software or driver installation, no particular operating system, and no periodic calibration.  penveu is targeted at the education and enterprise markets.  An independent source estimates the interactive whiteboard market to grow to approximately $1.8 billion in revenue in 2012.  However, penveu also has the unique ability to turn the estimated over 80 million projectors and 10 million large screen displays that are currently installed worldwide into interactive display devices.  The retail price of penveu will be less than 25% of the average price of a typical interactive whiteboard and, unlike an interactive whiteboard, penveu will not require the time and expense of installation.  penveu will be offered and sold through our website, other online retailers and catalogs.  During the three months ended June 30, 2012, we made significant investments in development, marketing and infrastructure associated with penveu to position this important product for a successful launch.

LIQUIDITY AND CAPITAL RESOURCES

Consolidated Cash Flows

Cash and cash equivalents decreased $2.2 million from December 31, 2011 to June 30, 2012 and increased $3.5 million from December 31, 2010 to June 30, 2011.  Cash flows are impacted by operating, investing and financing activities.

Operating Activities

Trends in cash flows from operating activities for the six months ended June 30, 2012 and 2011 are generally similar to the trends in our earnings except for the (recovery of)/provision for uncollectible accounts and returns, provision for excess and obsolete inventories, depreciation and amortization and amortization of stock-based compensation.  Cash used in operating activities totaled $2.3 million for the six months ended June 30, 2012, compared to net loss of $2.1 million.  Provision for uncollectible accounts and returns decreased $5,000 for the six months ended June 30, 2012 compared to the same period in 2011.  Provision for excess and obsolete inventories increased $20,000 for the six months ended June 30, 2012 compared to the same period in 2011.  Depreciation and amortization decreased $56,000 for the six months ended June 30, 2012 compared to the same period in 2011.  Amortization of stock-based compensation increased $140,000 for the six months ended June 30, 2012 compared to the six months ended June 30, 2011 primarily due to stock options issued during the first and second quarter of 2012. See Note 2 in the notes to condensed consolidated financial statements for more information on stock-based compensation.

Changes in assets and liabilities result primarily from the timing of production, sales, purchases and payments except for the increase in inventory during the quarter which was primarily due to the purchase of parts for penveu and parts associated with an interworking product where the primary customer has delayed the launch of its product.  Changes in assets and liabilities generally tend to even out over time and result in trends in cash flows from operating activities generally reflecting earnings trends.

Investing Activities

Cash used in investing activities totaled $805,000 and cash provided by investing activities totaled $2.8 million for the six months ended June 30, 2012 and 2011, respectively. Cash used in or provided by investing activities in each of the periods related principally to our investments in marketable securities, additions to property and equipment and capitalized software purchases.  Additions to property and equipment and capitalized software were $229,000 for the six months ended June 30, 2012, compared to $157,000 for the six months ended June 30, 2011.  The additions for the six months ended June 30, 2012 primarily related to software and equipment purchases for our newly announced product, penveu™, and equipment purchases for our manufacturing function.  The additions for the six months ended June 30, 2011 primarily related to software and equipment purchases for our manufacturing, engineering and administrative functions.  Purchases of marketable securities were $4.8 million and $1.1 million for the six months ended June 30, 2012 and 2011, respectively.  Proceeds from the sale of marketable securities increased to $4.2 million for the six months ended June 30, 2012, compared to $4.1 million for the six months ended June 30, 2011.

16

Financing Activities

Net cash provided by financing activities totaled $821,000 for the six months ended June 30, 2012, consisting solely of proceeds from the exercise of stock options.  Net cash provided by financing activities totaled $469,000 for the six months ended June 30, 2011, also consisting solely of proceeds from the exercise of stock options.

Restructuring Charge

On September 30, 2010, we initiated a restructuring plan to mitigate gross margin erosion by reducing manufacturing and procurement costs, streamline research and development expense and focus remaining resources on key strategic growth areas, and reduce selling and administrative expenses through product rationalization and consolidation of support functions.  Under the 2010 restructuring plan, we reduced our worldwide work force by 39 employees, including the closure of our European engineering and support center located in Chaville, France.  As a result of the 2010 restructuring plan, we recorded a restructuring charge of approximately $3.3 million, classified as an operating expense, in the third quarter of 2010 related to future cash expenditures to cover employee severance and benefits and other related costs.  Cash payments, net of currency translation adjustments, during the three and six months ended June 30, 2011 were approximately $141,000 and $1.2 million, respectively.  The remaining liability as of June 30, 2011 was $29,000.  These amounts were paid out under the restructuring plan by the end of 2011.

Commitments

At June 30, 2012, we had no material commitments to purchase capital assets; however, planned capital expenditures for the remainder of 2012 are estimated at approximately $150,000, a significant portion of which relates to enhancements to our manufacturing equipment and tools.  At June 30, 2012, we had $6,000 of non-cancelable purchase commitments for product tooling and testing as part of the normal course of business.  Our significant long-term obligations are operating leases on facilities and our phone system and future debt payments.  We have not paid any dividends since our inception and do not anticipate paying any dividends in 2012.

Other

Management believes that borrowing availability under the revolving credit facility, together with cash on hand, will be sufficient to meet our liquidity needs for working capital, capital expenditures and debt service.  To the extent that our actual operating results or other developments differ from our expectations, our liquidity could be adversely affected.

We periodically evaluate our liquidity requirements, alternative uses of capital, capital needs and available resources in view of, among other things, our capital expenditure requirements and estimated future operating cash flows.  As a result of this process, we have in the past and may in the future seek to raise additional capital, refinance or restructure indebtedness, issue additional securities, repurchase shares of our common stock or take a combination of such steps to manage our liquidity and capital resources.  In the normal course of business, we may review opportunities for acquisitions, joint ventures or other business combinations.  In the event of any such transaction, we may consider using available cash, issuing additional equity securities or increasing the indebtedness of the Company or its subsidiaries.

Critical Accounting Policies

There have been no significant changes to our critical accounting policies from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2011.

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Risk

We are exposed to adverse movements in foreign currency exchange rates because we conduct business on a global basis and, in some cases, in foreign currencies.  The Company’s operations in France were transacted in the local currency and converted into U.S. Dollars based on published exchange rates for the periods reported and were therefore subject to risk of exchange rate fluctuations.  The Euro to U.S. Dollar translation accounted for charges of $1,000 and $15,000 for the three months ended June 30, 2012 and 2011, respectively.  The Euro to U.S. Dollar translation accounted for charges of $12,000 and $18,000 for the six months ended June 30, 2012 and 2011, respectively.  This risk was significantly reduced due to the closure of our French operations at the end of 2010.

Market Price Risk

We had no equity hedge contracts outstanding as of June 30, 2012 or December 31, 2011.

Interest Rate Risk

Our investments are subject to interest rate risk.  Interest rate risk is the risk that our financial condition and results of operations could be adversely affected due to movements in interest rates.  We invest our cash in a variety of interest-earning financial instruments, including bank time deposits, money market funds, and variable rate and fixed rate obligations of corporations and national governmental entities and agencies.  Due to the demand nature of our money market funds and the short-term nature of our time deposits and debt securities portfolio, these assets are particularly sensitive to changes in interest rates.  We manage this risk through investments with shorter-term maturities and varying maturity dates.

A hypothetical 50 basis point increase in interest rates would result in an approximate decrease of less than 1% in the fair value of our available-for-sale securities at June 30, 2012.  This potential change is based on sensitivity analyses performed on our marketable securities at June 30, 2012.  Actual results may differ materially.  The same hypothetical 50 basis point increase in interest rates would have resulted in an approximate decrease of less than 1% in the fair value of our available-for-sale securities at December 31, 2011.

We maintain a $5.0 million revolving bank credit facility maturing December 19, 2013 with an applicable interest rate on any outstanding balances under the credit facility based on London Interbank Offered Rate (“LIBOR”) plus 1.0% to 1.5% applicable margin rate based on certain factors included in our credit agreement.  The interest rate on the borrowings under the revolving credit facility was 2.0% and 1.8% at June 30, 2012 and December 31, 2011, respectively.  The unused portion of the credit facility is subject to an unused facility fee ranging from .25% to .75% depending on total deposits with the creditor.  A hypothetical 50 basis point increase in LIBOR would increase annual interest expense on this credit facility by $17,500.  All borrowings under this facility are secured by marketable securities.  Subsequent to June 30, 2012 and prior to the Company’s filing of the condensed consolidated financial statements, the outstanding balance on the credit facility was repaid.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company’s management, under the supervision of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), performed an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of the end of the period covered by this quarterly report. Based on that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures are designed, and are effective, to give reasonable assurance that the information required to be disclosed by the Company in reports that it files under the Securities Exchange Act of 1934 is accumulated and communicated to management, including the CEO and CFO, to allow timely decisions regarding disclosure and that information is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission.

18

Changes in Internal Controls

The Company maintains a system of internal controls that is designed to provide reasonable assurance that its books and records accurately reflect, in all material respects, the transactions of the Company and that its established policies and procedures are adhered to.  From time to time the Company may experience changes to its internal controls due, for example, to employee turnover, re-balancing of workloads, extended absences and promotions of employees.  However, there were no changes in our internal controls over financial reporting during the quarter ended June 30, 2012 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

French Restructuring Litigation:  Twenty-five former employees (“Plaintiffs”) of Interphase SAS, a subsidiary of Interphase Corporation, brought suit in France against Interphase SAS alleging various causes of action and rights to damages relating to claims of wrongful dismissal of employment, specific French employment indemnities, general economic losses, and contractual claims relating specifically to their employment relationship and contracts entered into between the individual and Interphase SAS.  The lawsuits were filed between November 2010 and April 2011 and are pending in the Labor Court of Boulogne-Billancourt, France and the Administrative Court of Cergy-Pontoise, France.  The various claims and assertions arise from, and relate to, the Plaintiffs’ release from employment as part of the restructuring actions taken during the third quarter of 2010.  See Note 6 in the notes to the condensed consolidated financial statements for more information regarding the restructuring plan.  The updated statement of claim is for an aggregate payment of approximately €3.1 million, which translated to approximately $3.9 million at June 30, 2012, related to these claims.  The Company believes that the Plaintiffs’ claims are without merit and plans to continue to vigorously defend itself in this lawsuit.

On March 22, 2012, a hearing was conducted with the Labor Court of Boulogne-Billancourt, France related to the claims of twenty-three of the twenty-five former employees.  On May 31, 2012, the Court reported that the four judges’ votes were split; therefore, another hearing of the Court will be scheduled.  The same four judges will hear the case again, along with a professional judge from another court to ensure that a majority decision will be reached.  A date has not yet been scheduled for this hearing.

On May 22, 2012, a hearing was conducted with the Labor Court of Boulogne-Billancourt, France related to the claims of one of the twenty-five former employees.  On July 31, 2012, the Court reported that the four judges’ votes were split; therefore, another hearing of the Court will be scheduled.  The same four judges will hear the case again, along with a professional judge from another court to ensure that a majority decision will be reached.  A date has not yet been scheduled for this hearing.

On June 12, 2012, a hearing was conducted with the Labor Court of Boulogne-Billancourt, France related to the claims of one of the twenty-five former employees.  The Labor Court postponed the hearing on this case until May 28, 2013 or until the Administrative Court rules on this case.

Patent-infringement Litigation:  On April 7, 2011, Interphase was named as one of the defendants in a lawsuit filed by Mosaid Technologies (“Mosaid”) pending in the United States District Court for the Eastern District of Texas.  The complaint includes allegations that Interphase has infringed and is still infringing upon a certain registered U.S. patent to which Mosaid has enforcement rights.  The sole infringement allegation directed at Interphase appears to concern communications controller chips that Interphase purchases (indirectly) from Freescale Semiconductor, Inc. (“Freescale”), another defendant in the infringement allegation, which are used in several of Interphase’s products.

The complaint requests a judgment that Mosaid’s patents have been and are being infringed upon and, accordingly, an award of an unspecified amount of damages, plus interest and costs, as well as injunctive relief and any other remedies available under law.  Because the complaint claims the alleged infringing conduct is willful, it also requests treble damages and attorneys’ fees under the applicable U.S. patent statute.

19

Interphase does not know if there is any merit to Mosaid’s allegations.  Nevertheless, Interphase intends, and understands that Freescale intends, to vigorously defend the allegations; and to the extent that the infringement claim relates to the Freescale chips used in Interphase’s products, Freescale will also defend Interphase and indemnify Interphase against damages in the lawsuit.

Fair Value Disclosures [Text Block]

NOTE 3.  -  MARKETABLE SECURITIES

Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in accordance with accounting principles generally accepted in the United States, and expands disclosures about fair value measurements.  The Company follows ASC 820 in its valuation of its marketable securities.  ASC 820 defines fair value as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 classifies the levels used to measure fair value into the following hierarchy:

Level 1 – Valuations based on quoted prices in active markets for identical assets and liabilities that the reporting entity has the ability to obtain at the measurement date.  This level provides the most reliable evidence of fair value.

Level 2 – Valuations based on one or more quoted prices in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs that are observable other than quoted prices for the asset or the liability; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

The Company’s investments in marketable securities primarily consist of investments in debt securities, which are classified as available for sale and presented as current assets on the accompanying condensed consolidated balance sheets. Earnings from debt securities are calculated on a yield to maturity basis and recorded in the results of operations. Unrealized gains or losses for the periods presented were included in other comprehensive income (loss). Realized gains and losses are computed based on the specific identification method and were not material for the periods presented. Marketable securities are used to secure the Company’s credit facility.  The fair values of marketable securities were estimated using the market approach.

Financial assets, measured at fair value, by level within the fair value hierarchy were as follows (in thousands):

		June 30, 2012						December 31, 2011
	Fair Value Hierarchy	Cost		Unrealized Gain		Estimated Fair Value		Cost		Unrealized Gain		Estimated Fair Value

NOTE 2.  - STOCK-BASED COMPENSATION

Stock Options: During the six months ended June 30, 2012, the Company issued 136,000 stock options that vest over a one to four year period and expire ten years from date of grant.  The weighted average exercise price of these stock options is $5.27.  During the six months ended June 30, 2011, the Company issued 215,000 stock options that vest over a three to four year period and expire ten years from the date of grant. The weighted average exercise price of these stock options is $2.00.  Compensation expense related to these stock options was $104,000 and $46,000 for the three months ended June 30, 2012 and 2011, respectively.  Compensation expense related to these stock options was $177,000 and $71,000 for the six months ended June 30, 2012 and 2011, respectively.

During the six months ended June 30, 2012, the Company also issued 448,000 stock options with performance-based vesting conditions for the years ending December 31, 2012, 2013, 2014, and 2015, the achievement of which would result in pro rata vesting per year in February 2013, 2014, 2015, and 2016, respectively. The weighted average exercise price of these stock options is $4.76.  During the six months ended June 30, 2011, the Company issued 10,000 stock options with performance-based vesting conditions related to non-financial objectives for November 2011 and January 2012 and revenue objectives for the years ending December 31, 2012, 2013 and 2014, the achievement of which would result in vesting per year in February 2013, 2014 and 2015.  All stock options with performance-based conditions expire ten years from date of grant.  Of the stock options outstanding at June 30, 2012, 680,300 are subject to the achievement of certain performance conditions.  The performance conditions related to approximately 27,000 of these stock options were deemed probable as of June 30, 2012.  Compensation expense related to performance-based stock options, for which vesting was deemed probable, was $40,000 and $4,000 for the three months ended June 30, 2012 and 2011, respectively.  Compensation expense related to performance-based stock options, for which vesting was deemed probable, was $85,000 and $15,000 for the six months ended June 30, 2012 and 2011, respectively.  The performance conditions related to the remaining options were not deemed probable at June 30, 2012; therefore no compensation expense related to these options has been recorded.

The weighted-average remaining contractual life of stock options outstanding and exercisable at June 30, 2012 and 2011 is 3.28 years and 1.65 years, respectively.

The following table summarizes the combined stock option activity under all of the plans:

	Number of Options			Weighted Average Option Price
Balance, December 31, 2011		1,332,473		$	4.21
Granted		584,000			4.88

Balance, June 30, 2012		1,618,858		$	4.42

Option Valuation: The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with weighted-average assumptions based on the grant date.

Restricted Stock: The Interphase Corporation 2004 Long-Term Stock Incentive Plan provides for grants of bonus stock awards (“restricted stock”) to its directors and certain employees at no cost to the recipient.  Holders of restricted stock are entitled to cash dividends, if declared, and to vote their respective shares.  Restrictions limit the sale or transfer of these shares during a predefined vesting period, currently ranging from three to six years, and in some cases vesting is subject to the achievement of certain performance conditions. During the six months ended June 30, 2012, the Company issued 9,000 shares of restricted stock.  During the six months ended June 30, 2011, the Company issued 72,000 shares of restricted stock.  Upon issuance of restricted stock under the plan, unearned compensation equivalent to the market value at the date of grant is recorded as a reduction to shareholders’ equity and subsequently amortized to expense over the respective restriction periods.  Compensation expense related to restricted stock was $36,000 and $50,000 for the three months ended June 30, 2012 and 2011, respectively.  Compensation expense related to restricted stock was $69,000 and $106,000 for the six months ended June 30, 2012 and 2011, respectively.  As of June 30, 2012, there was $330,000 of total unamortized compensation cost related to unvested restricted stock remaining to be recognized. The expense is expected to be recognized over a weighted-average period of 2.5 years.  As of December 31, 2011, there was $479,000 of total unamortized compensation cost related to unvested restricted stock which was expected to be recognized over a weighted-average period of 3.0 years.  The following table summarizes the restricted stock activity for the six months ended June 30, 2012:

	Restricted Stock Shares			Weighted Average Grant Date Value
Nonvested restricted stock at December 31, 2011		225,941		$	2.67

NOTE 11.  -  RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-12, Comprehensive Income (Topic 220), Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05.  This ASU deferred the ASU 2011-05 requirement that companies present reclassification adjustments for each component of accumulated other comprehensive income (“AOCI”) in both net income and other comprehensive income on the face of the financial statements.  Companies are still required to present reclassifications out of AOCI on the face of the financial statements or disclose those amounts in the notes to the financial statements.  This ASU also defers the requirement to report reclassification adjustments in interim periods.  This ASU is effective for interim and annual periods beginning after December 15, 2011 and is to be applied retrospectively.  The Company’s adoption of this update did not have a material impact on the consolidated financial statements.

In June 2011, the FASB issued ASU 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income.  This update requires that all nonowner changes in stockholders’ equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements.  This ASU is effective for interim and annual periods beginning after December 15, 2011 and is to be applied retrospectively.  The Company’s adoption of this update did not have a material impact on the consolidated financial statements.

In May 2011, the FASB issued ASU 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.  The amendments in this ASU generally represent clarification of Topic 820, but also include instances where a particular principle or requirement for measuring fair value or disclosing information about fair value measurements has changed.  This update results in common principles and requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) and International Financial Reporting Standards (“IFRS”).  The amendments are effective for interim and annual periods beginning after December 15, 2011 and are to be applied prospectively.  Early application is not permitted.  The Company’s adoption of this update did not have a material impact on the consolidated financial statements.

NOTE 6.  -  RESTRUCTURING CHARGE

On September 30, 2010, the Company initiated a restructuring plan to mitigate gross margin erosion by reducing manufacturing and procurement costs, streamline research and development expense and focus remaining resources on key strategic growth areas, and reduce selling and administrative expenses through product rationalization and consolidation of support functions.  Under the 2010 restructuring plan, the Company reduced its worldwide work force by 39 employees, including the closure of its European engineering and support center located in Chaville, France.  As a result of the 2010 restructuring plan, the Company recorded a restructuring charge of approximately $3.3 million, classified as an operating expense, in the third quarter of 2010 related to future cash expenditures to cover employee severance and benefits and other related costs.  Cash payments, net of currency translation adjustments, during the three and six months ended June 30, 2011 were approximately $141,000 and $1.2 million, respectively.  The remaining liability as of June 30, 2011 was $29,000.  These amounts were paid out under the restructuring plan by the end of 2011.

NOTE 5.  -  INCOME TAXES

The Company records a valuation allowance when it is “more likely than not” that all or a portion of a deferred tax asset will not be realized.  Management reviews all available positive and negative evidence, including the Company’s current and past performance, the market environment in which the Company operates, the utilization of past tax credits, length of carry back and carry forward periods, existing contracts or sales backlog that will result in future profits, as well as other factors.  The Company continues to maintain a valuation allowance on all of the net deferred tax assets for the periods presented.  Until an appropriate level of profitability is sustained, the Company expects to continue to record a full valuation allowance on future tax benefits except for those that may be generated in foreign jurisdictions.  The effective income tax rates for the periods presented differ from the U.S. statutory rate as the Company continues to provide a full valuation allowance for the net deferred tax assets at June 30, 2012 and 2011.

Stockholders' Equity Note Disclosure [Text Block]

NOTE 9.  -  SHAREHOLDERS’ EQUITY

The Board of Directors adopted a Shareholder Rights Plan (the “Plan”) and, under the Plan, declared a non-taxable dividend, paid at the close of business on August 9, 2011 (the “Record Date”), of one common share purchase right (a “Right”) for each outstanding share of Common Stock.  From the Record Date until the Rights become exercisable, the Rights will be attached to all outstanding shares of Common Stock and, therefore, will be represented by the certificates evidencing the shares of Common Stock and transferrable only with the shares of Common Stock.  A Right will be exercisable, upon certain conditions, to purchase one share of Common Stock from the Company at a price of $39, subject to adjustment.  The Rights will become exercisable, and separate from the shares of Common Stock, upon the earlier of:

(1)  ten business days following the date of the first public announcement (the “Stock Acquisition Date”) that a person or a group of affiliated or associated persons has acquired, or obtained the right to acquire, beneficial ownership of 15% or more of the outstanding shares of Common Stock (an “Acquiring Person”), or

(2)  ten business days (or such later date as the Board of Directors may determine) following the commencement of a tender or exchange offer that, if consummated, would result in a person or group of persons becoming an Acquiring Person.

Upon a Stock Acquisition Date, each holder of a Right (other than an Acquiring Person) will be entitled to receive, upon exercise of the Right, shares of Common Stock at a 50% discount.  Also, if, at any time following a Stock Acquisition Date, the Company is acquired in a merger or business combination and its Common Stock is exchanged or converted, or if 50% or more of the Company’s assets, cash flow or earning power is sold or transferred, then each holder of a Right (other than an Acquiring Person) will be entitled to receive, upon exercise of the Right, shares of the acquirer’s common stock at a 50% discount.  Further, at any time after a person or group of persons becomes an Acquiring Person, but before any person or group of persons becomes the beneficial owner of 50% or more of the outstanding shares of Common Stock, the Company may cause each exercisable Right to be exchanged for one share of Common Stock.  The Rights will expire at the close of business on July 29, 2021, or such other date as the Board of Directors may determine under certain circumstances.  The Board of Directors may terminate the Plan or cause the Company to redeem the Rights, at a price of $0.001 per Right, at any time before the earlier of a Stock Acquisition Date or the expiration of the Rights.  The Company has reserved 90,315,210 shares of Common Stock for possible issuance upon exercise of Rights under the Plan.
