NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. The Company and Summary of Significant Accounting Policies

The Company

MoSys, Inc. (the “Company”) was incorporated in California in September 1991, and reincorporated in September 2000 in Delaware. The Company’s strategy and primary business objective is to be an IP-rich fabless semiconductor company focused on the development and sale of integrated circuit (IC) products. Prior to 2011, the Company’s primary business activities were designing, developing, marketing and licensing high-performance semiconductor memory and high-speed parallel and serial interface, or SerDes, intellectual property (IP) used by the semiconductor industry and communications, networking and storage equipment manufacturers. Since 2011, the Company has developed two IC product lines under the “Bandwidth Engine” and “LineSpeed” product names. Bandwidth Engine ICs combine the Company’s proprietary high-density embedded memory with its high-speed 10 gigabits per second and higher interface technology. In March 2013, the Company announced the LineSpeed IC product line, which is comprised of non-memory based, high-speed SerDes devices with gearbox or retimer functionality that convert lanes of data received on line cards into different configurations and/or ensure signal integrity. Both product lines are initially being marketed to networking and telecommunications systems companies. The Company’s future success and ability to achieve and maintain profitability depends on its success in developing a market for its ICs.

The accompanying condensed consolidated financial statements of the Company have been prepared without audit in accordance with the rules and regulations of the Securities and Exchange Commission (SEC). The condensed consolidated balance sheet at December 31, 2013 has been derived from the audited consolidated financial statements at that date. Certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (GAAP) have been condensed or omitted in accordance with these rules and regulations. The information in this report should be read in conjunction with the Company’s consolidated financial statements and notes thereto included in its most recent annual report on Form 10-K filed with the SEC.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary to summarize fairly the Company’s financial position, results of operations and cash flows for the interim periods presented. The operating results for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or for any other future period.

Basis of Presentation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. The Company’s fiscal year is the calendar year.

Reclassification

Certain prior year amounts have been reclassified to conform to the current year presentation. The reclassification includes reclassifying inventory as a separate line item, which was previously included in the prepaid expenses and other current assets line item of the condensed consolidated balance sheets. Revenue line items have been reclassified to create a separate line item for product revenue and to include licensing revenue in the royalty and other line item. The amounts for the prior periods have been reclassified to be consistent with the current year presentation and have no impact on previously reported total assets, total stockholders’ equity or net loss.

Use of Estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses recognized during the reported period. Actual results could differ from those estimates.

Table of Contents

Cash Equivalents and Investments

The Company has invested its excess cash in money market accounts, certificates of deposit, corporate debt, government agency and municipal debt securities and considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. Investments with original maturities greater than three months and remaining maturities less than one year are classified as short-term investments. Investments with remaining maturities greater than one year are classified as long-term investments. Management generally determines the appropriate classification of securities at the time of purchase. All securities are classified as available-for- sale. The Company’s available-for-sale short-term and long-term investments are carried at fair value, with the unrealized holding gains and losses reported in accumulated other comprehensive income. Realized gains and losses and declines in the value judged to be other than temporary are included in the other income, net line item in the consolidated statements of operations and comprehensive loss. The cost of securities sold is based on the specific identification method.

Fair Value Measurements

The Company measures the fair value of financial instruments using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, as follows:

Level 1— Inputs used to measure fair value are unadjusted quoted prices that are available in active markets for the identical assets or liabilities as of the reporting date.

Level 2— Pricing is provided by third party sources of market information obtained through the Company’s investment advisors rather than models. The Company does not adjust for or apply any additional assumptions or estimates to the pricing information it receives from advisors. The Company’s Level 2 securities include cash equivalents and available-for-sale securities, which consisted primarily of certificates of deposit, corporate debt, and government agency and municipal debt securities from issuers with high quality credit ratings. The Company’s investment advisors obtain pricing data from independent sources, such as Standard & Poor’s, Bloomberg and Interactive Data Corporation, and rely on comparable pricing of other securities because the Level 2 securities are not actively traded and have fewer observable transactions. The Company considers this the most reliable information available for the valuation of the securities.

Level 3— Unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment are used to measure fair value. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The determination of fair value for Level 3 investments and other financial instruments involves the most management judgment and subjectivity.

Allowance for Doubtful Accounts

The Company establishes an allowance for doubtful accounts to ensure that its trade receivables balances are not overstated due to uncollectibility. The Company performs ongoing customer credit evaluations within the context of the industry in which it operates and generally does not require collateral from its customers. A specific allowance of up to 100% of the invoice value is provided for any problematic customer balances. Delinquent account balances are written off after management has determined that the likelihood of collection is remote. The Company grants credit only to customers deemed creditworthy in the judgment of management. There was no allowance for doubtful accounts receivable at March 31, 2014 and December 31, 2013.

Revenue Recognition

General

The Company generates revenue from the sales of IC products and licensing of its IP. The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery or performance has occurred, the sales price is fixed or determinable, and collectibility is reasonably assured. Evidence of an arrangement generally consists of signed agreements or customer purchase orders.

Royalty

The Company’s licensing contracts typically also provide for royalties based on the licensee’s use of the Company’s memory technology in their currently shipping commercial products. The Company recognizes royalties in the quarter in which it receives the licensee’s report.

Table of Contents

IC products

The Company sells products both directly to customers, as well as through distributors. Revenue from sales directly to customers is generally recognized at the time of shipment. The Company records an estimated allowance, at the time of shipment, for future returns and other charges against revenue consistent with the terms of sale. IC product revenue and costs relating to sales made through distributors with rights of return or stock rotation are deferred until the distributors sell the product to end customers due to the Company’s inability to estimate future returns and credits to be issued. Distributors are generally able to return up to 10% of their purchases for slow, non-moving or obsolete inventory for credit every six months. At the time of shipment to distributors, an accounts receivable for the selling price is recorded, as there is a legally enforceable right to receive payment, and inventory is relieved, as legal title to the inventory is transferred upon shipment. Revenues are recognized upon receiving notification from the distributors that products have been sold to end customers. Distributors provide information regarding products and quantity, end customer shipments and remaining inventory on hand. The associated deferred margin is included in the deferred revenues line item in the condensed consolidated balance sheets. The Company recorded initial IC product revenue in 2012, and a reserve for returns has been recorded due to the product’s early stage deployment in customer systems.

Licensing

Licensing revenue consists of fees earned from license agreements, development services and support and maintenance. For stand-alone license agreements or license deliverables in multi-deliverable arrangements that do not require significant development, modification or customization, revenues are recognized when all revenue recognition criteria have been met. Delivery of the licensed technology is typically the final revenue recognition criterion met, at which time revenue is recognized. If any of the criteria are not met, revenue recognition is deferred until such time as all criteria have been met. Support and maintenance revenue is recognized ratably over the period during which the obligation exists, typically 12 months. Licensing revenue was $41,000 and $188,000 for the three months ended March 31, 2014 and 2013, respectively.

Cost of Net Revenue

Cost of net revenue consists primarily of direct and indirect costs of IC product sales and engineering personnel costs directly related to maintenance and support services specified in licensing agreements. Maintenance and support typically includes engineering support to assist in the commencement of production of a licensee’s products.

Goodwill

The Company reviews goodwill for impairment on an annual basis or whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. The Company first assesses qualitative factors to determine whether it is more-likely-than-not that the fair value of the reporting unit is less than the carrying amount as a basis for determining whether it is necessary to perform the two-step impairment test. If the qualitative assessment warrants further analysis, the Company compares the fair value of the reporting unit to its carrying value. The fair value of the reporting unit is determined using the market approach. If the fair value of the reporting unit exceeds the carrying value of net assets of the reporting unit, goodwill is not impaired, and the Company is not required to perform further testing. If the carrying value of the reporting unit’s goodwill exceeds its implied fair value, then the Company must record an impairment charge equal to the difference. The Company has determined that it has a single reporting unit for purposes of performing its goodwill impairment test. As the Company uses the market approach to assess impairment in the second step of the analysis, the price of its common stock is an important component of the fair value calculation. If the Company’s stock price continues to experience significant price and volume fluctuations, this will impact the fair value of the reporting unit, which can lead to potential impairment in future periods. The Company performed step one of the annual impairment test in September 2013, and concluded no factors indicated impairment of goodwill. As of March 31, 2014, the Company had not identified any factors to indicate there was an impairment of its goodwill and determined that no additional impairment analysis was required.

Intangible Assets

Intangible assets acquired in business combinations, referred to as purchased intangible assets, are accounted for based on the fair value of assets purchased and are amortized over the period in which economic benefit is estimated to be received. Identifiable intangible assets relating to business combinations and the patent license were as follows (dollar amounts in thousands):

|  | March 31, 2014 |
|  | Life (years) |  | Gross Carrying Amount |  | Accumulated Amortization |  | Net Carrying Value |
Developed technology |  | 3-5 |  | $ | 9,240 |  | $ | 8,364 |  | $ | 876 |
Patent license |  | 7 |  | 780 |  | 251 |  | 529 |
Total |  |  |  | $ | 10,020 |  | $ | 8,615 |  | $ | 1,405 |

|  | December 31, 2013 |
|  | Life (years) |  | Gross Carrying Amount |  | Accumulated Amortization |  | Net Carrying Value |
Developed technology |  | 3-5 |  | $ | 9,240 |  | $ | 8,142 |  | $ | 1,098 |
Patent license |  | 7 |  | 780 |  | 223 |  | 557 |
Total |  |  |  | $ | 10,020 |  | $ | 8,365 |  | $ | 1,655 |

Amortization expense has been included in research and development expense in the condensed consolidated statements of operations and comprehensive loss. The estimated aggregate amortization expense to be recognized in future years is approximately $0.8 million for the remainder of 2014, $0.3 million for 2015 and $0.1 million annually for 2016, 2017 and 2018.

Per Share Amounts

Basic net loss per share is computed by dividing net loss for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share gives effect to all potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of incremental shares of common stock issuable upon the exercise of stock options, vesting of stock awards and purchases under the employee stock purchase plan. As of March 31, 2014 and 2013, stock awards to purchase approximately 10,173,000 and 9,970,000 shares, respectively, were excluded from the computation of diluted net loss per share as their inclusion would be anti-dilutive.

Comprehensive Loss

Comprehensive loss includes unrealized gains and losses on available-for-sale securities. Realized gains and losses on available-for-sale securities are reclassified from accumulated other comprehensive loss and included in other income, net in the condensed consolidated statements of operations and comprehensive loss. All amounts recorded in the three months ended March 31, 2014 and 2013 are not considered significant.

Note 3. Commitments and Contingencies

Indemnification

In the ordinary course of business, the Company enters into contractual arrangements under which it may agree to indemnify the counterparties from any losses incurred relating to breach of representations and warranties, failure to perform certain covenants, or claims and losses arising from certain events as outlined within the particular contract, which may include, for example, losses arising from litigation or claims relating to past performance. Such indemnification clauses may not be subject to maximum loss clauses. The Company has entered into indemnification agreements with its officers and directors. No material amounts were reflected in the Company’s condensed consolidated financial statements for the three months ended March 31, 2014 or 2013 related to these indemnifications.

The Company has not estimated the maximum potential amount of indemnification liability under these agreements due to the limited history of prior claims and the unique facts and circumstances applicable to each particular agreement. To date, the Company has not made any material payments related to these indemnification agreements.

Legal Matters

The Company is not a party to any material legal proceeding that the Company believes is likely to have a material adverse effect on its condensed consolidated financial position or results of operations. From time to time, the Company may be subject to legal proceedings and claims in the ordinary course of business. These claims, even if not meritorious, could result in the expenditure of significant financial resources and diversion of management efforts.

Note 4. Business Segments and Significant Customers

The Company operates in one business segment and uses one measurement of profitability for its business. Net revenue attributed to the United States and to all foreign countries is based on the geographical location of the customer.

Note 5. Income Tax Provision

The Company determines deferred tax assets and liabilities based upon the differences between the financial statement and tax bases of the Company’s assets and liabilities using tax rates in effect for the year in which the Company expects the differences to affect taxable income. A valuation allowance is established for any deferred tax assets for which it is more likely than not that all or a portion of the deferred tax assets will not be realized.

The Company files U.S. federal and state and foreign income tax returns in jurisdictions with varying statutes of limitations. The Company is currently under tax examination in India. The 2003 through 2013 tax years generally remain subject to examination by federal, state and foreign tax authorities. As of March 31, 2014, the Company has not recorded any liability for unrecognized tax benefits related to uncertain tax positions.

Note 6. Stock-Based Compensation

The Company recorded approximately $1.5 million and $0.9 million of stock-based compensation expense for the three months ended March 31, 2014 and 2013, respectively. The expense relating to stock options is recognized on a straight-line basis over the requisite service period, usually the vesting period, based on the grant-date fair value. The unamortized compensation cost, net of expected forfeitures, as of March 31, 2014 was $5.1 million related to stock options and is expected to be recognized as expense over a weighted average period of approximately 2.38 years. The expense related to restricted stock units is recognized over a three-to-five year vesting period and is based on the fair value of the underlying stock on the dates of grant. The unamortized compensation cost, net of expected forfeitures, as of March 31, 2014 was $1.5 million related to restricted stock units and is expected to be recognized as expense over a weighted average period of approximately 2.95 years.

The Company presents the tax benefits resulting from tax deductions in excess of the compensation cost recognized from the exercise of stock options as financing cash flows in the condensed consolidated statements of cash flows. For the three months ended March 31, 2014 and 2013, there were no such tax benefits associated with the exercise of stock options due to the Company’s loss position.

Table of Contents

The total fair value of shares subject to outstanding options vested during the three months ended March 31, 2014 and 2013 calculated using the Black-Scholes valuation method was $0.8 million for each period. The total intrinsic value of employee stock options exercised during the three months ended March 31, 2014 and 2013 was $0.5 million and $0.4 million, respectively.

Valuation Assumptions

The fair value of the Company’s share-based payment awards for the three months ended March 31, 2014 and 2013 was estimated on the grant dates using the Black-Scholes valuation option-pricing model with the following assumptions:

|  | Three Months Ended March 31, |
Employee stock options: |  | 2014 |  | 2013 |
Risk-free interest rate |  | 1.5% - 1.7% |  | 0.6% |
Volatility |  | 56.9% - 57.5% |  | 58.5% - 59.1% |
Expected life (years) |  | 4.0-5.0 |  | 4.0 |
Dividend yield |  | 0% |  | 0% |

The risk-free interest rate was derived from the Daily Treasury Yield Curve Rates as published by the U.S. Department of the Treasury as of the grant date for terms equal to the expected terms of the options. The expected volatility was based on the historical volatility of the Company’s stock price over the expected term of the options. The expected term of options granted was derived from historical data based on employee exercises and post-vesting employment termination behavior. A dividend yield of zero is applied because the Company has never paid dividends and has no intention to pay dividends in the near future.

The stock-based compensation expense recorded is adjusted based on estimated forfeiture rates. An annualized forfeiture rate has been used as a best estimate of future forfeitures based on the Company’s historical forfeiture experience. The stock-based compensation expense will be adjusted in later periods if the actual forfeiture rate is different from the estimate.

Employee Stock Purchase Plan

In June 2010, the Company’s stockholders approved the 2010 Employee Stock Purchase Plan (ESPP). A total of 2,000,000 shares of common stock have been reserved for issuance under the ESPP. The ESPP, which is intended to qualify under Section 423 of the Internal Revenue Code, is administered by the board of directors or the compensation committee of the board of directors. The ESPP provides that eligible employees may purchase up to $25,000 worth of the Company’s common stock annually over the course of two six-month offering periods. The purchase price to be paid by participants is 85% of the price per share of the Company’s common stock either at the beginning or the end of each six-month offering period, whichever is less. On September 1, 2010, the Company commenced the first offering period under the ESPP. On February 28, 2014, approximately 140,000 shares of common stock were issued at an aggregate purchase price of $434,000 under the ESPP. As of March 31, 2014, there were approximately 920,000 shares authorized and unissued under the ESPP.

Note 7. Related Party Transactions

In February 2012, the Company entered into a strategic development and marketing agreement with Credo Semiconductor (Hong Kong) Ltd. (Credo), a privately- funded, fabless semiconductor company, to develop, market and sell integrated circuits. Two of the Company’s executive officers between them loaned a total of $250,000 to Credo for a portion of the seed funding needed by Credo to commence its integrated circuit design efforts. These loans may be converted into minority equity interests in Credo. The agreement and its amendments calls for the Company to make payments to Credo upon Credo achieving certain development and verification milestones towards the development of IC products and provides the Company with exclusive sales and marketing rights for such IC products. To date, the Company has paid Credo $2.8 million for achievement of additional development milestones, as well as for mask costs and wafer purchases from third-party vendors. All amounts incurred have been recorded as research and development expenses. Under the agreement, the first $2.5 million of gross profits generated by the sale of these integrated circuits will be retained by the Company, and, thereafter, the gross profits will be shared equally by the Company and Credo. In the first half of 2013, the Company announced prototype samples of SerDes products developed pursuant to the strategic development and marketing agreement.

Without limiting the foregoing, the words “believes,” “anticipates,” “expects,” “intends,” “plans,” “projects,” or similar expressions are intended to identify forward-looking statements. Our actual results could differ materially from those expressed or implied by these forward-looking statements as a result of various factors, including the risk factors described below in Risk Factors and elsewhere in this report and under Item 1A of our annual report on Form 10-K for the year ended December 31, 2013. We undertake no obligation to update publicly any forward-looking statements for any reason, except as required by law, even as new information becomes available or events occur in the future.

Company Overview

Our strategy and primary business objective is to be an IP-rich fabless semiconductor company focused on the development and sale of integrated circuits, or ICs, for the high-speed networking, communications, storage and computing markets. Prior to 2011, our primary business activities were designing, developing, marketing and licensing high-performance semiconductor memory and high-speed parallel and serial interface, or SerDes I/O, intellectual property (IP) used by semiconductor industry and communications, networking and storage equipment manufacturers. Since 2011, we have developed two IC product lines under the “Bandwidth Engine®” and “LineSpeed™” product names. Bandwidth Engine ICs combine our proprietary 1T-SRAM® high-density embedded memory and high-speed serial interface with our intelligent access technology and a highly efficient interface protocol. In March 2013, we announced the LineSpeed IC product line, which is comprised of non-memory, high-speed SerDes I/O devices with gearbox and retimer functionality, which convert lanes of data received on line cards into different configurations and/or ensure signal integrity. Certain SerDes products have been developed under a strategic development and marketing agreement with Credo Semiconductor Ltd., or Credo. For those products developed by Credo, the first $2.5 million of gross profits generated by us from the sale of these products will be retained by us as reimbursement of the development costs. Thereafter, all gross profits from the sale of the Credo-developed products worldwide will be shared equally by Credo and us.

Revenue from sales of our IC products is increasing, as we continue to support existing design-win customers and actively pursue additional design wins for the use of our ICs in networking and communication equipment. We have established initial pricing of our IC products ordered to date, but longer-term volume prices will be subject to negotiations with our customers and may vary substantially from these initial prices. Our future success and ability to achieve and maintain profitability will be dependent on the manufacturing, marketing and sales of our IC products into networking, communications and other end- customer applications markets requiring high performance.

Sources of Revenue

IC product. IC product revenue is generally recognized at the time of shipment to our customers. An estimated allowance is recorded, at the time of shipment, for future returns and other charges against revenue consistent with the terms of sale. IC product revenue and costs relating to sales made through distributors with rights of return and stock rotation are deferred until the distributors sell the product to end customers due to our inability to estimate future returns and credits to be issued. At the time of shipment to distributors, an accounts receivable for the selling price is recorded, as there is a legally enforceable right to receive payment, inventory is relieved, as legal title to the inventory is transferred upon shipment, and the associated deferred margin is recorded as deferred revenues in the condensed consolidated balance sheets. Revenues are recognized upon receiving notification from the distributors that products have been sold to end customers.

Royalty. Royalty revenue represents amounts earned under provisions in our memory licensing contracts that require our licensees to report royalties and make payments at a stated rate based on actual units manufactured or sold by licensees for products that include our memory IP. Our license agreements require the licensee to report the manufacture or sale of products that include our technology after the end of the quarter in which the sale or manufacture occurs, and we recognize royalties in the quarter in which we receive the licensee’s report.

15

Table of Contents

The timing and level of royalties are difficult to predict. They depend on the licensee’s ability to market, produce and sell products incorporating our technology. Many of the products of our licensees that are currently subject to licenses from us are used in consumer products, such as electronic game consoles, for which demand can be seasonal.

Licensing. Licensing revenue, which is included in royalty and other revenue, consists of fees earned from license agreements, development services, prepaid pre-production royalties, and support and maintenance. Our licensing revenue consists primarily of fees for providing circuit design, layout and design verification and granting licenses to customers that embed our technology into their products. The vast majority of our contracts allow for milestone billing based on work performed. Fees billed prior to revenue recognition are recorded as deferred revenue.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make certain estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. On an ongoing basis we make these estimates based on our historical experience and on assumptions that we consider reasonable under the circumstances. Actual results may differ from these estimates, and reported results could differ under different assumptions or conditions. Our significant accounting policies and estimates are disclosed in Note 1 of the “Notes to Consolidated Financial Statements” in our Annual Report on Form 10-K for the year ended December 31, 2013. As of March 31, 2014, there have been no material changes to our significant accounting policies and estimates.

Table of Contents

Cost of net revenue increased for the three months ended March 31, 2014, compared with the same period of 2013, primarily due to the increase in product material and testing costs related to IC shipments.

Gross profit decreased for the three months ended March 31, 2014, compared with the same period of 2013, primarily due to the decrease in our royalty revenue, which has no associated costs, coupled with the increase in IC shipments. Gross margin percentage decreased for the three months ended March 31, 2014, compared with the same period of 2013, primarily due to the shift in revenue mix from royalty revenue, which has no associated costs, to product revenue.

Research and Development.

Percentage of total net revenue |  | 530 | % | 399 | % |  |  |  |

Our research and development expenses include costs related to the development of our IC products and amortization of intangible assets. We expense research and development costs as they are incurred.

The $1.7 million increase was primarily due to an increase in stock-based compensation charges, computer-aided design software tools, personnel-related expenses and development costs of our Bandwidth Engine and LineSpeed Gearbox IC products. R&D expense is expected to fluctuate in absolute dollars primarily due to timing of masks and test chip expenditures related to tape-outs of new IC products. Tape-outs of new products also drive higher computer-aided design and consulting costs.

Research and development expenses included stock-based compensation expense of $1.1 million and $0.6 million for the three months ended March 31, 2014 and 2013, respectively.

The provision for the three months ended March 31, 2014 and 2013 was primarily attributable to taxes on earnings of our foreign subsidiaries and branches. We believe that, based on the history of our operating losses and other factors, the weight of available evidence indicates that it is more likely than not that we will not be able to realize the benefit of our net operating losses, which are primarily generated in the United States. Accordingly, a full valuation reserve has been recorded against our net deferred tax assets.

Liquidity and Capital Resources; Changes in Financial Condition

Cash Flows

As of March 31, 2014, we had cash, cash equivalents and long and short-term investments of $45.7 million and had total working capital of $34.4 million. Our primary capital requirements are to fund working capital, including development of our IC products, and any acquisitions that we make that require cash consideration or expenditures.

Net cash used in operating activities was $6.3 million for the first three months of 2014, which primarily resulted from our net loss of $8.1 million and $0.1 million in the net reduction in assets and liabilities, partially offset by non-cash charges, including stock-based compensation expense of $1.5 million and depreciation and amortization expenses of $0.4 million. The changes in assets and liabilities primarily related to the timing of the collection of receivables from customers and payments to vendors.

Net cash used in operating activities was $5.0 million for the first three months of 2013, which primarily resulted from our net loss of $5.0 million, a gain on sale of assets of $0.6 million and $0.7 million in the net reduction in assets and liabilities, partially offset by non-cash charges, including stock-based compensation expense of $0.9 million and depreciation and amortization expenses of $0.5 million. The changes in assets and liabilities primarily related to the timing of the collection of receivables from customers and payments to vendors.

Net cash provided by investing activities was $2.5 million for the first three months of 2014, and included net amounts transferred to cash and cash equivalents from investments of $2.6 million, which did not impact our liquidity, partially offset by $0.1 million for purchases of fixed assets.

Net cash provided by investing activities was $6.7 million for the first three months of 2013, and included net amounts transferred to cash and cash equivalents from investments of $6.2 million that did not impact our liquidity and $0.6 million in proceeds from the sale of assets.

Our financing activities in the first three months of 2014 and 2013 primarily consisted of proceeds from the exercise of stock options and our employee stock purchase plan.

Our future liquidity and capital requirements are expected to vary from quarter to quarter, depending on numerous factors, including:

· level of revenue;

· cost, timing and success of technology development efforts;

· inventory levels, timing of product shipments and length of billing and collection cycles;

· fabrication costs, including mask costs of our ICs, currently under development;

· variations in manufacturing yields, materials costs and other manufacturing risks;

· costs of acquiring other businesses and integrating the acquired operations; and

· profitability of our business.

We expect our cash expenditures to continue to exceed receipts in 2014 as our revenues will not be sufficient to offset our operating expenses, which include significant research and development expenditures for the expansion and fabrication of our IC products. We believe our existing cash, cash equivalents and investments, along with our existing capital and cash generated from operations, if any, to be sufficient to meet our capital requirements for the foreseeable future. There can be no assurance that our capital is sufficient to fund operations until such time as we begin to achieve positive cash flows. Our previous shelf registration statement declared effective in November 2010 was fully utilized and expired in 2013. We expect to file a new shelf registration statement to enable us to raise additional capital in the future. However, there can be no assurance that such funding will be available to us on favorable terms, if at all. The failure to raise capital when needed could have a material adverse effect on our business and financial condition.

ITEM 3. Qualitative and Quantitative Disclosures about Market Risk

Our investment portfolio consists of money market accounts, certificates of deposit, corporate debt, government agency and municipal debt securities. The portfolio dollar-weighted average maturity of these investments is within 12 months. Our primary objective with this investment portfolio is to invest available cash while preserving principal and meeting liquidity needs. No single security should exceed 5% of the portfolio or $2.0 million at the time of purchase. In accordance with our investment policy, we place investments with high credit quality issuers and limit the amount of credit exposure to any one issuer. These securities, which approximated $45.2 million as of March 31, 2014 and earned an average annual interest rate of approximately 0.3% during the first three months of 2014, are subject to interest rate and credit risks. We do not have any investments denominated in foreign currencies, and, therefore, are not subject to foreign currency risk on such investments.

ITEM 4. Controls and Procedures

Disclosure Controls and Procedures. Our management is responsible for establishing and maintaining adequate internal control over our financial reporting. Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934. Based on this evaluation, our management concluded that as of March 31, 2014, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting. During the first quarter of 2014, there was no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
