Organization | ||||||||||||||||
Integrated Silicon Solution, Inc. (the “Company”) was incorporated in California on October 27, 1988 and reincorporated in Delaware on August 9, 1993. The Company is a fabless semiconductor company that designs and markets high performance integrated circuits for the following key markets: (i) automotive, (ii) communications, (iii) industrial, medical and military, and (iv) digital consumer. The Company’s primary products are low and medium density DRAM and high speed and low power SRAM. | ||||||||||||||||
In January 2010, the Company formed a separate business unit, Giantec Semiconductor, Inc. (Giantec), which designs and markets application specific standard products (ASSP) primarily EEPROMs and SmartCards. As part of this formation, a third party invested approximately $3.8 million in Giantec. On December 30, 2010, Giantec received an additional direct investment of $4.0 million from outside investors, and as a result the Company’s ownership interest was reduced to approximately 44% and the Company was required to deconsolidate Giantec. In August 2011, the Company sold approximately 37% of its shares in Giantec and, on August 31, 2011, Giantec merged with Maxllent Corp. thereby reducing the Company's ownership interest in Giantec to approximately 19.85%. In fiscal 2013, the Company sold its remaining investment in Giantec for approximately $4.3 million which resulted in a pre-tax gain of approximately $0.2 million. The Company's consolidated financial statements reflect accounting for Giantec on a consolidated basis from January 1, 2010 through December 30, 2010. For the period from December 31, 2010 through August 31, 2011, the Company accounted for Giantec on the equity method and the Company's results included its percentage share of Giantec’s results of operations in interest and other income, net. From September 1, 2011 until the sale of its investment in June 2013, the Company accounted for Giantec on the cost basis and its investment in Giantec was included in other assets on the Company's balance sheets. | ||||||||||||||||
On January 31, 2011, the Company acquired Si En Integration Holdings Limited (Si En) and the Company’s financial results reflect accounting for Si En on a consolidated basis from the date of acquisition (See Note 18). | ||||||||||||||||
On September 14, 2012, the Company acquired Chingis Technology Corporation (Chingis) and the Company’s financial results reflect accounting for Chingis on a consolidated basis from the date of acquisition (See Note 19). | ||||||||||||||||
Basis of Presentation | ||||||||||||||||
The accompanying consolidated financial statements include the accounts of Integrated Silicon Solution, Inc. and its wholly and majority owned subsidiaries, after elimination of all significant intercompany accounts and transactions. | ||||||||||||||||
Cash and Cash Equivalents | ||||||||||||||||
The Company considers all highly liquid investments with an original maturity of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents are maintained at various financial institutions. | ||||||||||||||||
Investments | ||||||||||||||||
Debt securities and marketable equity securities are classified as “available-for-sale”. Available-for-sale securities are recorded at fair value with unrealized gains and losses included in accumulated other comprehensive income (loss). Realized gains and losses and declines in value judged to be other-than-temporary on available-for-sale securities are included in interest and other income, net. The cost of fixed income securities sold is based on the specific identification method and the weighted-average method is used to determine the cost basis of publicly traded equity securities disposed of. Interest and dividends on securities classified as available-for-sale are included in interest and other income, net. | ||||||||||||||||
The Company accounts for non-marketable equity and other equity investments for which it does not have control over the investee as equity method investments when the Company has the ability to exercise significant influence, but not control, over the investee. The Company accounts for non-marketable equity and and other equity investments as non-marketable cost method investments when the equity method does not apply. The Company's non-marketable equity and other equity investments are included in other assets in its consolidated balance sheet. | ||||||||||||||||
The Company regularly reviews its investments to determine whether a decline in fair value below the cost basis is other than temporary. If the decline in fair value is determined to be other than temporary, the cost basis of the investment is written down to fair value, and the amount of the write-down is included in the consolidated statements of operations. | ||||||||||||||||
Inventories | ||||||||||||||||
Inventories are stated at the lower of cost (first-in, first-out) or market. The Company’s inventory valuation process is done on a part-by-part basis. Lower of cost or market adjustments, specifically identified on a part-by-part basis, reduce the carrying value of the related inventory and take into consideration reductions in sales prices. Determining the market value of inventories on hand and at distributors as of the balance sheet date involves numerous judgments, including projecting average selling prices and sales volumes for future periods and costs to complete products in work in process inventories. When market values are below the Company’s costs, the Company records a charge to cost of goods sold to write down inventories to estimated market value in advance of when the inventories are actually sold. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required that may adversely affect the Company’s operating results. If actual market conditions are more favorable, the Company may have higher gross margins when such products are sold. The Company writes down to zero dollars the carrying value of inventory on hand that has aged over one year (two years for wafer and die bank) to cover estimated excess and obsolete exposures, unless adjustments are made based on management’s judgments for newer products, end of life products, planned inventory increases or strategic customer supply. Once established, these write-downs are considered permanent. | ||||||||||||||||
Property and Equipment | ||||||||||||||||
Property and equipment are stated at cost. Depreciation and amortization are computed using the straight-line method, based upon the shorter of the estimated useful lives ranging from two to ten years for property and equipment and from 25 to 50 years for buildings or the lease term for improvements to leased properties. | ||||||||||||||||
Goodwill and Purchased Intangible Assets | ||||||||||||||||
The Company tests goodwill and other indefinite-lived intangible assets for impairment on an annual basis and between annual tests if events or circumstances require an interim impairment assessment. For goodwill, the Company either makes a qualitative assessment prior to proceeding to step 1 of the annual goodwill impairment test or performs a two-step impairment test. If the Company makes a qualitative assessment and it determines that the fair value of the reporting unit is less than its carrying amount, the Company would perform step 1 of the annual goodwill impairment test and, if necessary, proceed to step 2. Otherwise, no further evaluation is necessary. For the two-step impairment test, in the first step, the Company compares the fair value of the reporting unit to its carrying value, including goodwill. The Company determines the fair value of the reporting unit based on a weighting of income and market approaches. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and no further testing is performed. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then the Company performs the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill. If the carrying value of a reporting unit’s goodwill exceeds its implied fair value, the Company records an impairment loss equal to the difference. | ||||||||||||||||
Purchased intangible assets other than goodwill are amortized over their useful lives unless these lives are determined to be indefinite. Purchased intangible assets with definite lives are carried at cost less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets, generally six months to eight years. | ||||||||||||||||
The Company has acquired in-process research and development (IPR&D) projects as the result of its business combinations (see Note 6). The fair values of the acquired IPR&D projects were determined through estimates and valuation techniques based on the terms and details of the related acquisitions. Upon completion of development for each project, the acquired IPR&D will be amortized over its useful life. The Company assesses the status of each IPR&D project quarterly to evaluate whether the carrying value has been impaired. | ||||||||||||||||
Valuation of Long-Lived Assets and Certain Identifiable Intangibles | ||||||||||||||||
The Company evaluates the recoverability of property, plant and equipment and identifiable intangible assets through the performance of periodic reviews to determine whether facts and circumstances exist that would indicate that the carrying amounts of property, plant and equipment and identifiable intangible assets exceed their fair values. If facts and circumstances indicate that the carrying amount of property, plant and equipment and identifiable intangible assets might not be fully recoverable, projected undiscounted net cash flows associated with the related asset or group of assets over their estimated remaining useful life is compared to their respective carrying amounts. In the event that the projected undiscounted cash flows are not sufficient to recover the carrying value of the assets, the assets are written down to their estimated fair values based on the expected discounted future cash flows attributable to the assets. | ||||||||||||||||
Revenue Recognition and Accounts Receivable Allowances | ||||||||||||||||
Revenue from product sales (net of any applicable value added tax) to the Company’s direct customers is recognized upon shipment provided that persuasive evidence of a sales arrangement exists, the price is fixed or determinable, title has transferred, collection of resulting receivables is reasonably assured, there are no customer acceptance requirements and there are no remaining significant obligations. The Company makes estimates of potential future product returns and sales allowances related to current period product revenue. Management analyzes historical returns, changes in customer demand, and acceptance of products when evaluating the adequacy of sales returns and allowances. Estimates made by the Company may differ from actual product returns and sales allowances. These differences may materially impact reported revenue and amounts ultimately collected on accounts receivable. | ||||||||||||||||
A portion of the Company’s sales is made to distributors under agreements that provide the possibility of certain price adjustment credits, as discussed below, and to return qualifying products for credit, as determined by the Company, in order to reduce the amounts of slow-moving, discontinued or obsolete product from their inventory. These agreements limit such returns to a certain percentage of the value of the Company's shipments to that distributor during the prior quarter. In addition, distributors are allowed to return unsold products if the Company terminates the relationship with the distributor. | ||||||||||||||||
Certain distributors are granted price adjustment credits related to many of their sales to their customers. Price adjustment credits are granted when a distributor’s standard cost (i.e., the Company’s sales price to the distributor) does not provide the distributor with an appropriate margin on its sales to its customers. As a result, the distributor may request and receive a price adjustment credit from the Company to allow the distributor to earn an appropriate margin on the transaction. Certain distributors are also granted price adjustment credits in the event of a price decrease subsequent to the date the product was shipped and billed to the distributor. Generally, the Company will provide a credit equal to the difference between the price paid by the distributor (less any prior credits on such products) and the new price for the product multiplied by the quantity of such product in the distributor’s inventory at the time of the price decrease. Certain of the Company’s distributor arrangements may allow or require the granting of price concessions below the Company’s cost for a product. | ||||||||||||||||
Given the uncertainties associated with the levels of returns and other price adjustment credits that will be issued to these distributors, the sales price to distributors is not fixed or determinable until the distributors resell the products to their customers. Therefore, the Company defers revenue recognition from sales to these distributors until the distributors have sold the products to their end customers. | ||||||||||||||||
Title to the inventory transfers to a distributor at the time of shipment or delivery to the distributor, and payment from the distributor is due in accordance with the Company's standard payment terms. These payment terms are not contingent upon the distributors’ sale of the products to their customers. Upon title transfer to distributors, inventory is reduced for the cost of goods shipped, the deferred distributor margin (sales less cost of sales) is recorded as a liability and an account receivable is recorded. | ||||||||||||||||
The deferred costs of sales to distributors may be subject to impairment. The Company monitors the level and nature of product returns from distributors as well as the levels of inventory held at distributors. On a quarterly basis, the Company reviews the inventory held at distributors in terms of the Company’s inventory valuation policy and records a charge to cost of goods sold for all known lower of cost or market and excess and obsolescence issues. | ||||||||||||||||
In addition, the Company monitors collectibility of accounts receivable primarily through review of its accounts receivable aging. When facts and circumstances indicate the collection of specific amounts or from specific customers is at risk, the Company assesses the impact on amounts recorded for bad debts and, if necessary, will record a charge in the period such determination is made. | ||||||||||||||||

Foreign Currency Translation | ||||||||||||||||
The Company uses the local currency as its functional currency for all foreign subsidiaries. Translation adjustments, which result from the process of translating foreign currency financial statements into U.S. dollars, are included in the accumulated other comprehensive income component of stockholders’ equity. | ||||||||||||||||
Advertising Costs | ||||||||||||||||
The Company expenses advertising costs as incurred and includes these costs in selling, general and administrative expenses in the consolidated statement of operations. Advertising costs totaled $79,000, $59,000 and $57,000 for the fiscal years ended September 30, 2013, 2012 and 2011, respectively. | ||||||||||||||||
Income Taxes | ||||||||||||||||
The Company accounts for income taxes under an asset and liability approach. Deferred income taxes reflect the impact of temporary differences between assets and liabilities recognized for financial reporting purposes and such amounts recognized for income tax reporting purposes. Valuation allowances are provided when necessary to reduce deferred tax assets to an amount that is more likely than not to be realized. Uncertain tax positions are recognized or derecognized based on the threshold and measurement of a tax position taken or expected to be taken in a tax return. U.S. income tax has not been provided on earnings of foreign subsidiaries to the extent that such earnings are considered to be indefinitely reinvested. | ||||||||||||||||
Stock-Based Compensation | ||||||||||||||||
Stock-based compensation is measured at the grant date, based on the estimated fair value of the award. The Company amortizes the compensation costs on a straight-line basis over the requisite service period of the option, which is generally the option vesting term of four years. The Company estimates the fair value of stock options using the Black-Scholes valuation model. The Black-Scholes valuation model requires the Company to estimate key assumptions such as expected term, volatility and risk free interest rates to determine the fair value of a stock option. The estimates of these key assumptions are based on historical information and judgment regarding market factors and trends. | ||||||||||||||||
Use of Estimates | ||||||||||||||||
The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Such estimates relate to the useful lives and residual value of fixed assets, the fair value of investments, allowances for doubtful accounts and customer returns, valuation allowances for deferred tax assets, inventory write-downs, potential reserves relating to litigation matters, accrued liabilities, and other reserves. The Company bases its estimates and judgments on its historical experience, knowledge of current conditions and its beliefs of what could occur in the future, given available information. Actual results may differ from those estimates, and such difference, may be material to the financial statements. | ||||||||||||||||
Fair Value of Financial Instruments | ||||||||||||||||
The Company’s financial instruments consist primarily of cash and cash equivalents, marketable securities, accounts receivable and accounts payable. The Company believes that the carrying amounts of the financial instruments approximate their respective fair values. When there is no readily available market data, the Company may make fair value estimates, which may not necessarily represent the amounts that will be realized in a current or future sale of these assets. | ||||||||||||||||
Concentration of Credit Risk | ||||||||||||||||
The Company operates in one business segment, which is to design, develop, and market high performance SRAM, DRAM, and other semiconductor products. The Company markets and distributes its products on a worldwide basis, primarily to original equipment manufacturers, contract manufacturers, and distributors. The Company performs ongoing credit evaluations of its customers’ financial condition and generally requires no collateral. In fiscal 2013, revenue from the Company’s largest and second largest distributor accounted for approximately 17% and 11%, respectively, of the Company's total net sales. In fiscal 2012, revenue from the Company’s largest and second largest distributor accounted for approximately 14% and 13%, respectively, of the Company's total net sales. In fiscal 2011, revenue from the Company’s largest and second largest distributor, accounted for approximately 15% and 12% of the Company's total net sales. | ||||||||||||||||
The Company maintains cash, cash equivalents, and short-term investments with various high credit quality financial institutions. The Company’s investment policy is designed to limit exposure to any one institution. The Company performs periodic evaluations of the relative credit standing of those financial institutions that are considered in its investment strategy. The Company is exposed to credit risk in the event of default by the financial institutions or issuers of investments to the extent of the amount recorded on the balance sheet. To date, the Company has not incurred losses related to these investments. | ||||||||||||||||
Product Warranty and Indemnifications | ||||||||||||||||
The Company generally warrants its products against defects in materials and workmanship for a period of 12 months. Liability for a stated warranty period is usually limited to replacement of defective items or return of amounts paid. If there is a material increase in the rate of customer claims or the Company’s estimates of probable losses relating to specifically identified warranty exposures are inaccurate, the Company may record a charge against future cost of sales. Warranty expense has historically been immaterial to the Company’s financial statements. | ||||||||||||||||
The Company may be obligated to indemnify certain customers, distributors, suppliers, and subcontractors for attorney fees and damages and costs awarded against these parties in certain circumstances in which its products are alleged to infringe third party intellectual property rights, including patents, registered trademarks, or copyrights. The terms of the Company’s indemnification obligations are generally perpetual from the effective date of the agreement. In certain cases, there are limits on and exceptions to the Company’s potential liability for indemnification relating to intellectual property infringement claims. In addition, the Company has entered into indemnification agreements with its officers and directors, and the Company’s bylaws provide that indemnification may be provided to the Company’s agents. The Company has directors’ and officers’ insurance pursuant to which the Company may be reimbursed for certain indemnity expenses, subject to the insurers’ reservation of rights. The Company cannot estimate the amount of potential future indemnity expenses that it may be required to make. The amount of available directors’ and officers’ insurance may not be sufficient to cover the Company’s indemnity obligations, which may have a material adverse effect on the Company’s results of operations in future periods. | ||||||||||||||||
Net Income (Loss) Per Share | ||||||||||||||||
Basic and diluted net loss per share and basic net income per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted average number of common and dilutive common equivalent shares outstanding, if applicable, during the period. Common equivalent shares consist of the shares issuable upon the assumed exercise of stock options and awards under the treasury stock method. | ||||||||||||||||
Accounting Pronouncements | ||||||||||||||||
The following issued accounting pronouncements are not yet effective for the Company as of September 30, 2013. | ||||||||||||||||
Liabilities | ||||||||||||||||
In February 2013, the Financial Accounting Standards Board (FASB) issued guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of the guidance is fixed at the reporting date. Examples of obligations include debt arrangements, other contractual obligations, and settled litigation and judicial rulings. The guidance requires an entity to measure such obligations as the sum of the amount that the reporting entity agreed to pay on the basis of its arrangement among its co-obligors in addition to amounts the reporting entity expects to pay on behalf of its co-obligors. The guidance becomes effective for the Company beginning in the first quarter of fiscal 2015 and is not expected to have a material impact on the Company's consolidated financial statements. | ||||||||||||||||
Foreign Currency Matters | ||||||||||||||||
In March 2013, FASB issued guidance on when foreign currency translation adjustments should be released to net income. When a parent entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity, the parent is required to release any related cumulative translation adjustment into net income. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The guidance becomes effective for the Company beginning in the first quarter of fiscal 2015 and is not expected to have a material impact on the Company's consolidated financial statements. | ||||||||||||||||
Accounting Standards | ||||||||||||||||
On October 1, 2012, the Company adopted the following accounting standard, which did not have a material effect on its consolidated results of operations during such period or financial condition at the end of such period: | ||||||||||||||||
Comprehensive Income | ||||||||||||||||
In June 2011, FASB amended its guidance on the presentation of comprehensive income. This amendment eliminates the currently available option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. Under this amendment, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The Company elected to present the items of net income and other comprehensive income in two separate, but consecutive statements. Effective January 1, 2013, the Company adopted the FASB's standard regarding the reporting of reclassifications out of accumulated other comprehensive income. The new standard requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. | ||||||||||||||||
Reclassifications | ||||||||||||||||
Certain reclassifications have been made to prior year balances in order to conform to the current year’s presentation. |

Fair Value Measurements | ||||||||||||||||
Under FASB guidance, fair value is defined as the price expected to be received from the sale of an asset or paid to transfer a liability in a transaction between market participants at the measurement date. In determining fair value, the Company uses various valuation approaches, including quoted market prices and discounted cash flows. The FASB guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that the market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect a company’s judgment concerning the assumptions that market participants would use in pricing the asset or liability developed based on the best information available at that time. The fair value hierarchy is broken down into the following three levels based on the reliability of inputs: | ||||||||||||||||
• | Level 1 – Valuations based on quoted prices in active markets for identical instruments that the Company is able to access. Since valuations are based on quoted prices which are readily and regularly available in an active market, valuation of these products can be done without a significant degree of judgment. | |||||||||||||||
• | Level 2 – Valuations based on quoted prices in active markets for instruments that are similar, or quoted prices in markets that are not active for identical or similar instruments and model-derived valuations in which all significant inputs and significant value drives are observable in active markets. | |||||||||||||||
• | Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. | |||||||||||||||
As of September 30, 2013, the Company’s financial assets utilizing Level 1 inputs include short-term investment securities traded on an active securities exchange. The Company did not have any financial assets utilizing Level 2 or Level 3 inputs at September 30, 2013 and September 30, 2012. | ||||||||||||||||

During the fourth quarter of fiscal 2012, the Company recorded a $2.3 million charge to write-down its investment in SMIC due to the decline in fair market value being considered other than temporary. The Company uses the weighted-average cost method to determine the cost basis of its shares of SMIC. | ||||||||||||||||
In September 2012, the Company invested approximately $27.1 million in Nanya, which was comprised of common shares which are classified as available-for-sale securities and private placement shares which are accounted for on the cost-basis (See Note 4). The Company uses the weighted-average cost method to determine the cost basis of its shares of Nanya. | ||||||||||||||||
During fiscal 2013, the Company sold approximately 143.5 million shares of Nanya common stock for approximately $21.2 million which resulted in a pre-tax gain of approximately $12.0 million. | ||||||||||||||||

The Company has various deposits including deposits with suppliers for purchase guarantees and for customs clearance. These deposits are included in restricted assets. | ||||||||
In September 2012, the Company invested approximately $27.1 million in Nanya, which was comprised of common shares which are classified as available-for-sale securities and private placement shares which are accounted for on the cost-basis. The Company accounts for the private placement shares it acquired in Nanya on the cost-basis as these securities are restricted and the restrictions do not terminate within one year of the reporting date. In addition, as of September 30, 2013, the Company had pledged $5.4 million of its Nanya private placement shares with Nanya as collateral for the Company's accounts payable. During fiscal 2013, the Company reclassified its common shares in Nanya to short-term investments as the Company's intent is to sell these shares within one year. | ||||||||
In March 2012, the Company made an equity investment of $2.0 million in a private technology company headquartered in Hong Kong. At September 30, 2013, the Company's ownership interest was approximately 31%. This investment is accounted for under the equity method and the Company's results include its percentage share of such company's results of operations in interest and other income (expense), net. | ||||||||
On December 30, 2010, Giantec received an additional direct investment of $4.0 million from outside investors, and as a result the Company’s ownership interest was reduced to approximately 44% and the Company was required to deconsolidate Giantec and to record its retained interest in Giantec at fair value at the date of deconsolidation. As the additional investment received by Giantec was from new investors, the Company used the price paid by the new investors as a basis for determining the fair value of its investment in Giantec. As a result, the Company recorded a loss of approximately $30,000 in “Interest and other income, net,” which was the difference between the fair value of the Company’s retained interest in Giantec, and the carrying value of Giantec’s net assets and noncontrolling interest before the deconsolidation. In August 2011, the Company sold approximately 37% of its shares in Giantec for $2.2 million resulting in no gain and on August 31, 2011, Giantec merged with Maxllent Corp. thereby reducing the Company's ownership interest in Giantec to approximately 19.85%. In fiscal 2013, the Company sold its remaining investment in Giantec for approximately $4.3 million which resulted in a pre-tax gain of approximately $0.2 million. The Company's consolidated financial statements reflect accounting for Giantec on a consolidated basis from January 1, 2010 through December 30, 2010. For the period from December 31, 2010 through August 31, 2011, the Company accounted for Giantec on the equity method and the Company's results included its percentage share of Giantec’s results of operations in interest and other income, net. From September 1, 2011 until the sale of its investment in June 2013, the Company accounted for Giantec on the cost basis and its investment in Giantec was included in other assets on the Company's balance sheets. |

No additions to purchased intangible assets were recorded during fiscal 2013. During fiscal 2012, in connection with its acquisition of Chingis, the Company recorded $7.9 million of intangible assets (See Note 19). During fiscal 2011, in connection with its acquisition of Si En, the Company recorded $11.6 million of intangible assets (See Note 18). | ||||||||||||
During the fourth quarter of fiscal 2012, in connection with the Company's annual goodwill impairment test, the Company determined that the intangible assets acquired in the acquisition of Si En were impaired. The analysis indicated that there was no value attributable to the intangible assets and accordingly, the Company recorded an impairment charge of $8.9 million of which $5.4 million was included in cost of sales and $3.5 million was included in operating expenses. | ||||||||||||

During the fourth quarter of fiscal 2012, the Company completed the first step of its annual goodwill impairment test, which included examining the impact of current general economic conditions on its future prospects and the current level of its market capitalization. Based on this analysis, the Company concluded that goodwill related to its analog reporting unit was impaired. The Company's analog reporting unit's goodwill was originally recorded in connection with its acquisition of Si En. Therefore, the Company performed the second step of the impairment test to determine the implied fair value of goodwill. Specifically, the Company hypothetically allocated the estimated fair value of the analog reporting unit's equity as determined in the first step to recognized and unrecognized net assets, including allocations to intangible assets. The analysis indicated that there would be approximately $3.9 million remaining implied value attributable to goodwill and accordingly, the Company wrote off $4.3 million of its goodwill. |

Stock-Based Benefit Plans | ||||||||||||||||||||||||
The Company grants stock-based compensation awards under its 2007 Incentive Compensation Plan (the “2007 Plan”). The Company has outstanding grants under prior option plans, though no further grants can be made under these prior plans. At September 30, 2013, the total number of shares subject to options and awards outstanding under all plans was 5,621,000. At September 30, 2013, 2,255,000 shares were available for future grant under the 2007 Plan of which 35,000 shares were available for the grant of RSUs. Options generally vest ratably over a four-year period with a 6-month or 1-year cliff vest and then vesting ratably over the remaining period. Options granted prior to October 1, 2005 expire ten years after the date of grant; options granted after October 1, 2005 expire seven years after the date of the grant. RSUs generally vest annually over periods ranging from two years to four years based upon continued employment with the Company. | ||||||||||||||||||||||||
2007 Incentive Compensation Plan | ||||||||||||||||||||||||
On July 30, 2007, the Company’s stockholders approved, upon recommendation of the Company’s board of directors, the adoption of the 2007 Plan. The 2007 Plan is the successor to each of the 1998 Stock Plan, 1996 Nonstatutory Stock Plan and 1995 Director Stock Option Plan (the “Predecessor Plans”), and no further grants can be made under the Predecessor Plans. | ||||||||||||||||||||||||
The 2007 Plan permits the grant of stock options, stock appreciation rights, restricted stock awards, RSUs, performance shares and performance units. The Compensation Committee of the Company’s board of directors has the authority to determine the type of incentive award, as well as the terms and conditions of the award, under the 2007 Plan. | ||||||||||||||||||||||||
3,000,000 shares of the Company’s common stock were initially reserved for issuance under the 2007 Plan. To the extent any options outstanding under the Predecessor Plans subsequently terminate unexercised or any unvested shares outstanding under the Predecessor Plans are subsequently forfeited or repurchased by ISSI, the number of shares of common stock subject to those terminated options, together with the forfeited shares, are added to the share reserve available for issuance under the 2007 Plan, up to an additional 4,000,000 shares. On July 20, 2011, the Company's stockholders approved, upon a recommendation of the Company's board of directors, an amendment and restatement of the Company's 2007 Incentive Compensation Plan to increase the number of shares available for issuance thereunder by 2,000,000 shares, limit the number of awards other than options or stock appreciation rights that may be granted thereunder on or after the date of the special meeting to an aggregate of 263,100 and make certain other changes as set forth therein. On February 8, 2013, the Company's stockholders approved, upon a recommendation of the Company's board of directors, an amendment of the Company's 2007 Incentive Compensation Plan to increase the shares available for issuance thereunder by 2,000,000 shares. | ||||||||||||||||||||||||
2012 Inducement Option Plan | ||||||||||||||||||||||||
On July 26, 2012, the Company's board of directors authorized and approved the 2012 Inducement Option Plan (the "Inducement Plan") which was adopted and approved by the compensation committee of the board of directors on September 17, 2012. The purpose of the Inducement Plan was to provide awards of stock options to persons employed by Chingis as a material inducement to such individuals entering into employment with the Company or its subsidiaries upon the acquisition of Chingis by the Company. In this regard, on September 17, 2012, the Company made stock option grants under the Inducement Plan for an aggregate of 439,500 shares of the Company's common stock. The grants under the Inducement Plan were non-qualified stock options to purchase shares of the Company’s common stock and have the following terms: (i) an exercise price equal to $10.42 per share which was the fair market value of the Company’s common stock on the grant date of September 17, 2012, (ii) a term of seven years from the date of grant, and (iii) vesting as to 12.5% of the shares on the six (6) month anniversary of the employment start date, and as to 1/48th of the total shares each month thereafter until the option is fully vested subject to continued employment with the Company. | ||||||||||||||||||||||||
Other Stock Plans | ||||||||||||||||||||||||
The Company has outstanding grants under its 1998 Stock Plan, 1996 Nonstatutory Stock Plan and 1995 Director Stock Option Plan. Options generally vest ratably over a four-year period with a 6-month or 1-year cliff vest and then vesting ratably over the remaining period, except for options granted under the 1995 Director Stock Option Plan, which generally vest over 12 months. Options granted prior to October 1, 2005 expire ten years after the date of grant and options granted after October 1, 2005 expire seven years after the date of the grant. | ||||||||||||||||||||||||
The Company has shares of common stock reserved for future issuance under its 1995 Employee Stock Purchase Plan (ESPP). Offering periods prior to August 1, 2010 under the ESPP had a duration of six months and the purchase price was equal to 85% of the fair value of the common stock on the purchase date. As approved by the Board of Directors, effective August 1, 2010, shares under the ESPP will be purchased at a price equal to 85% of the lesser of the fair market value of the Company’s common stock as of the first day or the last day of each six-month purchase period. The offering periods under the 1995 Employee Stock Purchase Plan commence on approximately February 1 and August 1 of each year. During the fiscal years ended September 30, 2013, 2012 and 2011, 237,000 shares, 181,000 shares, and 167,000 shares were issued under the plan, respectively. As of September 30, 2013, 581,000 shares were available under the plan for future issuance. | ||||||||||||||||||||||||
Accounting for Stock-Based Compensation | ||||||||||||||||||||||||
Stock-based compensation cost is calculated by the Company on the date of grant using the fair value of the option as determined using the Black-Scholes option pricing model. The compensation cost is then amortized ratably over the vesting period of the individual option grants. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company estimates forfeitures based on its historical forfeiture rates as it believes these rates to be the most indicative of the Company’s expected forfeiture rate. | ||||||||||||||||||||||||
As of September 30, 2013, there was approximately $10.4 million of total unrecognized stock-based compensation expense under the Company’s stock option plans that will be recognized over a weighted-average period of approximately 2.47 years. Future stock option grants will add to this total whereas quarterly amortization and the vesting of the existing stock option grants will reduce this total. In addition, as of September 30, 2013, there was approximately $0.2 million of total unrecognized stock-based compensation expense under the Company’s ESPP that will be recognized over a weighted-average period of approximately 4 months. | ||||||||||||||||||||||||
Cash flows from tax benefits resulting from the exercise of stock options are classified as financing cash flows in the statement of cash flows. As the Company has a valuation allowance for certain of its deferred tax assets, a tax benefit associated with stock option exercises has not been realized or recognized. | ||||||||||||||||||||||||
The Company issues new shares of common stock upon exercise of stock options and upon vesting of RSUs. The total intrinsic value (market value on date of exercise less exercise price) of options exercised and RSUs vested during the fiscal years ended September 30, 2013, 2012 and 2011, was $7.0 million, $5.7 million and $3.5 million, respectively. | ||||||||||||||||||||||||

Valuation Assumptions | ||||||||||||||||||||||||
The Company uses the Black-Scholes option pricing model to estimate the fair value of the options granted. The Company estimates the expected term of options granted based upon historical exercise data. Estimated volatilities are based on historical stock price volatilities of the period immediately preceding the option grant that is equal in length to the option’s expected term. The Company believes that historical volatility is the best estimate of future volatility. The Company bases the risk- free interest rate on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term. The Company has never paid dividends and does not anticipate doing so over the expected life of the options and therefore used 0% for dividend yield. For offering periods prior to August 1, 2010 under the ESPP, the Company recorded compensation expense for the difference between the purchase price and the fair market value on the day of purchase. For offering periods subsequent to August 1, 2010, the Company uses the Black-Scholes option pricing model to estimate the fair value of stock purchase rights under its ESPP. | ||||||||||||||||||||||||
The estimated values of stock option grants and stock purchase rights, as well as the weighted average assumptions used in calculating these values during the fiscal years ended September 30, 2013, 2012 and 2011, were based on estimates at the date of grant as follows: | ||||||||||||||||||||||||

The Company issues RSUs from time to time. The estimated fair value of RSU awards is calculated based on the market price of the Company’s common stock on the date of grant. The weighted average grant date fair value of RSUs granted during the fiscal years ended September 30, 2013 , 2012 and 2011 was $9.14 per share, $9.42 per share and $7.82 per share, respectively. | ||||||||||||||||||||||||

Stockholders' Equity | ||||||||
The Company’s Restated Certificate of Incorporation provides for 70,000,000 authorized shares of common stock and 5,000,000 authorized shares of preferred stock. The terms of the preferred stock may be fixed by the board of directors, who have the right to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without any further vote or action by the stockholders. The rights of the holders of common stock are subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. | ||||||||
As of September 30, 2013, shares of common stock were reserved for future issuance as follows: | ||||||||
Common shares reserved under Employee Stock Purchase Plan | 581,000 | |||||||
Common shares reserved under stock option plans | 7,876,000 | |||||||
Common Stock Repurchases | ||||||||
In both fiscal 2013 and fiscal 2012, the Company did not repurchase any shares of its common stock in the open market. As of September 30, 2013, the Company had repurchased and retired an aggregate of 14,179,711 shares of common stock at a cost of approximately $88.5 million since September 2007. As of September 30, 2013, $19.8 million remained available under the existing share repurchase authorization. | ||||||||
The Company issues RSUs as part of its equity incentive plans. For a portion of RSUs granted, the number of shares issued on the date the RSUs vest is net of the statutory withholding requirements that the Company pays on behalf of its employees. During fiscal 2013, the Company withheld 59,501 shares to satisfy approximately $555,000 of employees’ tax obligations. During fiscal 2012, the Company withheld 56,849 shares to satisfy approximately $537,000 of employees’ tax obligations. Although the shares withheld are not issued, they are treated as common stock repurchases for accounting purposes, as they reduce the number of shares that would have been issued upon vesting. | ||||||||

Management has established a valuation allowance for a portion of the gross deferred tax assets based on management’s expectations of future taxable income and the actual taxable income during the three years ended September 30, 2013. The valuation allowance for deferred tax assets increased by $41,000 in fiscal 2013, increased by $2.7 million in fiscal 2012 and decreased by $40.5 million in fiscal 2011. Approximately $13.6 million of the valuation allowance is attributable to tax benefits of stock option deductions which will be credited to paid-in capital when recognized. | ||||||||||||
A reconciliation of the beginning and ending amount of the consolidated liability for unrecognized income tax benefits during the tax year ended September 30 is as follows: | ||||||||||||

Balance at the end of the year | $ | 3,052 | $ | 2,906 | $ | 4,533 | ||||||
The remaining amount of the unrecognized tax benefit as of September 30, 2013 is offset by a full valuation allowance. The Company does not anticipate a significant change in unrecognized tax benefits within the next twelve months except for any adjustments related to the expiration of the statute of limitations. | ||||||||||||
The Company anticipates the unrecognized tax benefits may increase during the year for items that arise in the ordinary course of business. These increases will be considered in the determination of the Company’s annual effective tax rate. The amount of the unrecognized tax benefit classified as a long term tax payable, if recognized, would reduce the annual income tax provision. | ||||||||||||
The Company’s policy to include interest and penalties related to unrecognized tax benefits within the Company’s provision for (benefit from) income taxes did not change. As of September 30, 2013, the Company has not accrued any potential penalties and interest related to these unrecognized tax benefits. | ||||||||||||
The Company files U.S., state and foreign income tax returns in jurisdictions with varying statutes of limitations during which such tax returns may be audited and adjusted by the relevant tax authorities. The 2006 through 2013 tax years generally remain subject to examination by federal and most state tax authorities, and tax years 2006 through 2013 generally remain subject to examination by foreign tax authorities. In addition, U.S. tax returns are open from the 2000 tax year through the 2003 tax year to the extent that net operating losses generated during these periods are being utilized in open tax periods. Also, U.S. tax returns are open for the tax years from 1996 through 2003 and from 2007 through 2011 to the extent research and development credits were generated during these periods and are being utilized in open years. |

As allowed under Section 401(k) of the Internal Revenue Code, the 401(k) Plan provides for tax-deferred salary contributions and after-tax contributions for eligible employees. The 401(k) Plan allows employees to contribute up to 75% of their eligible compensation to the 401(k) Plan on a pre-tax and after-tax basis, and effective November 1, 2011, the 401(k) Plan also allows employees to make Roth contributions. Employee contributions are limited to a maximum annual amount as set periodically by the Internal Revenue Code. The 401(k) Plan also allows employees who meet the age requirements and reach the 401(k) Plan contribution limits to make a catch-up contribution not to exceed the lesser of 75% of their eligible compensation or the limit set forth in the Internal Revenue Code. The catch-up contributions are not eligible for matching contributions. The 401(k) Plan allows for employer contributions and the Company has elected to make a contribution for the plan year beginning January 1, 2013 and ending December 31, 2013. The Company will match employee contributions in an amount equal to 50% of every dollar contributed by the employee up to 10% of the employees' eligible earnings. The matching contribution in a year will not exceed $6,000 for any participant. The Company contributions are subject to vesting of 25% for each year of service with the Company. The Company elected to make no matching contributions during the fiscal years ended September 30, 2012 and 2011. Administrative expenses relating to the plan are insignificant. | ||||||||||||
Deferred Compensation Plan | ||||||||||||
The Compensation Committee of the Board of Directors of the Company adopted the Non-qualified Deferred Compensation Plan (the Deferred Compensation Plan or NDCP), effective as of March 22, 2013. As required by applicable law, participation in the Deferred Compensation Plan is limited to a select group of management and highly-compensated employees of the Company and its participating subsidiaries and affiliates, which group includes the Company’s executive officers. Under the Deferred Compensation Plan, which is an unfunded and unsecured deferred compensation arrangement, a participant may elect to defer part of his or her base salary and/or commissions (if any), but not more than 50% of his or her base salary or commissions, and all or part of his or her eligible bonus (if any) or performance-based compensation (if any), in each case on a pre-tax basis. Such deferrals made by participants in the NDCP are at all times 100% vested. In addition, the Company and its participating subsidiaries and affiliates may, but are not required to, make matching or discretionary contributions to the accounts of participants in the NDCP. The matching or discretionary contributions (if any) made by the Company and/or its participating subsidiaries and affiliates may be subject to any vesting schedule determined by the Company when any such matching or discretionary contribution is made, but will vest in full upon a participant’s disability, death, separation from service due do retirement, or upon a “change in control” of the Company (as defined in the NDCP). The Company elected to make no matching or discretionary contributions during the fiscal year ended September 30, 2013. | ||||||||||||
The Company has a prior non-qualified deferred compensation plan; however, no employee contributions have been made to the prior plan since fiscal 1998. |

Patents and Licenses | ||||
In the semiconductor industry, it is not unusual for companies to receive notices alleging infringement of patents or other intellectual property rights of others. The Company has been, and from time-to-time expects to be, notified of claims that it may be infringing patents, maskwork rights or copyrights owned by third parties. If it appears necessary or desirable, the Company may seek licenses under patents that it is alleged to be infringing. Although patent holders commonly offer such licenses, licenses may not be offered and the terms of any offered licenses may not be acceptable to the Company. The failure to obtain a license under a key patent or intellectual property right from a third party for technology used by the Company could cause it to incur substantial liabilities and to suspend the manufacture of the products utilizing the invention or to attempt to develop non-infringing products, any of which could materially and adversely affect the Company’s business and operating results. Furthermore, there can be no assurance that the Company will not become involved in protracted litigation regarding its alleged infringement of third party intellectual property rights or litigation to assert and protect its patents or other intellectual property rights. Any litigation relating to patent infringement or other intellectual property matters could result in substantial cost and diversion of the Company’s resources. | ||||
Litigation | ||||
GSI Technology Inc. v. Integrated Silicon Solution, Inc., et al. | ||||
On October 2, 2013, GSI Technology Inc. (GSI) filed a Second Amended Complaint in a lawsuit filed earlier in 2013 solely against defendant United Memories, Inc. GSI named the Company as a new, second defendant in the Second Amended Complaint, and alleges claims against the Company for violation of the Sherman Act, violation of the Racketeering Influenced and Corrupt Organizations Act, Unfair Competition under California Business & Professions Code 17200, misappropriation of trade secrets, intentional interference with contract, and intentional interference with prospective economic advantage. GSI alleges that the Company conspired with United Memories, Inc. to harm GSI in connection with a bid from Cisco Systems, Inc., to misappropriate alleged GSI trade secrets, and to interfere with a contract between United Memories, Inc. and GSI. GSI seeks damages and injunctive relief. Before the Company was named as a defendant, the Court denied motions by GSI for temporary and preliminary injunctive relief. On December 6, 2013, the Company filed a motion to dismiss each of the causes of action alleged against the Company by GSI. The motion is currently pending. The Company believes it has meritorious defenses to the claims alleged by GSI and intend to defend this suit vigorously. | ||||
VAREP GmBH v. Integrated Silicon Solution, Inc. | ||||
On August 21, 2012, a lawsuit was filed against the Company in the Superior Court of California, County of Santa Clara by a former independent sales representative based in Germany named Varep GmbH (Varep), for the alleged underpayment of commissions (Case No. 112CV230846). The original complaint alleged 11 causes of action, including, among others, breach of contract, Labor Code violations, and violations of the Independent Wholesale Sales Representatives Contractual Relations Act. A demurrer by the Company challenging the legal sufficiency of the Complaint was sustained with leave to amend and a motion to strike portions of the initial complaint by the Company was granted in part and denied in part. On December 28, 2012, Varep filed a First Amended Complaint (FAC) asserting seven causes of action, including, among others, breach of contract and Labor Code violations. On January 7, 2013, the Company filed a demurrer challenging the legal sufficiency of the FAC and a motion to strike portions of the FAC. On February 19, 2013, the demurrer was sustained without leave to amend as to the causes of action for breach of the implied covenant of good faith and fair dealing and Labor Code violations and overruled with respect to other causes of action, and the motion to strike was granted in part to strike a claim for punitive damages on the cause of action for negligent misrepresentation and denied in other part. On March 4, 2013, the Company filed an answer to the remaining allegations of the FAC. The Company and the plaintiff entered into a settlement and mutual general release agreement and on August 22, 2013 the case was dismissed with prejudice. | ||||
Other Legal Proceedings | ||||
In the ordinary course of its business, the Company has been involved in a limited number of other legal actions, both as plaintiff and defendant, and could incur uninsured liability in any one or more of them. Although the outcome of these actions is not presently determinable, the Company believes that the ultimate resolution of these matters will not have a material adverse effect on its financial position, cash flows or results of operations. However, no assurances can be given with respect to the extent or outcome of any such litigation in the future. | ||||
Operating Leases | ||||
The Company leases various facilities and the land upon which its building in Taiwan is situated under operating lease agreements that expire at various dates through 2016. Minimum rental commitments under these leases are as follows (in thousands): | ||||

Total minimum rental commitments | $ | 1,760 | ||
Total rental expense, recorded on a straight-line basis, for the fiscal years ended September 30, 2013, 2012 and 2011 was approximately $1.4 million, $1.4 million and $1.1 million, respectively. | ||||
Commitments to Wafer Fabrication Facilities | ||||
The Company issues purchase orders for wafers to various wafer foundries. These purchase orders are generally considered to be cancelable. However, to the degree that the wafers have entered into work-in-process, as a matter of practice it becomes increasingly difficult to cancel the purchase order. As of September 30, 2013, the Company had approximately $31.6 million of purchase orders for which the related wafers had been entered into wafer work-in-process (i.e., manufacturing had begun). |

Acquisition of Si En | ||||
On January 31, 2011, the Company acquired 100% of the outstanding shares of Si En Integration Holdings Limited (Si En), a privately held fabless provider of high performance analog and mixed signal integrated circuits headquartered in Xiamen, China. The acquisition of Si En is part of a Company strategy to target additional revenue opportunities and attractive margins in non-memory markets. The purchase price was approximately $27.4 million in cash which included a $4.2 million holdback provision for a period of two years from the date of closing to secure certain Si En indemnification obligations. | ||||
The allocation of the purchase price of Si En includes both tangible assets and acquired intangible assets. The excess of the purchase price over the fair value allocated to the net assets is goodwill. The goodwill recognized was attributable primarily to expected synergies and the assembled workforce of Si En. The Company currently does not expect to receive a tax benefit for such goodwill. | ||||

Basis of Accounting, Policy | ' |
Basis of Presentation | |
The accompanying consolidated financial statements include the accounts of Integrated Silicon Solution, Inc. and its wholly and majority owned subsidiaries, after elimination of all significant intercompany accounts and transactions. | |
Cash and Cash Equivalents, Policy | ' |
Cash and Cash Equivalents | |
The Company considers all highly liquid investments with an original maturity of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents are maintained at various financial institutions. | |
Investment, Policy | ' |
Investments | |
Debt securities and marketable equity securities are classified as “available-for-sale”. Available-for-sale securities are recorded at fair value with unrealized gains and losses included in accumulated other comprehensive income (loss). Realized gains and losses and declines in value judged to be other-than-temporary on available-for-sale securities are included in interest and other income, net. The cost of fixed income securities sold is based on the specific identification method and the weighted-average method is used to determine the cost basis of publicly traded equity securities disposed of. Interest and dividends on securities classified as available-for-sale are included in interest and other income, net. | |
The Company accounts for non-marketable equity and other equity investments for which it does not have control over the investee as equity method investments when the Company has the ability to exercise significant influence, but not control, over the investee. The Company accounts for non-marketable equity and and other equity investments as non-marketable cost method investments when the equity method does not apply. The Company's non-marketable equity and other equity investments are included in other assets in its consolidated balance sheet. | |
The Company regularly reviews its investments to determine whether a decline in fair value below the cost basis is other than temporary. If the decline in fair value is determined to be other than temporary, the cost basis of the investment is written down to fair value, and the amount of the write-down is included in the consolidated statements of operations. | |
Inventory, Policy | ' |
Inventories | |
Inventories are stated at the lower of cost (first-in, first-out) or market. The Company’s inventory valuation process is done on a part-by-part basis. Lower of cost or market adjustments, specifically identified on a part-by-part basis, reduce the carrying value of the related inventory and take into consideration reductions in sales prices. Determining the market value of inventories on hand and at distributors as of the balance sheet date involves numerous judgments, including projecting average selling prices and sales volumes for future periods and costs to complete products in work in process inventories. When market values are below the Company’s costs, the Company records a charge to cost of goods sold to write down inventories to estimated market value in advance of when the inventories are actually sold. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required that may adversely affect the Company’s operating results. If actual market conditions are more favorable, the Company may have higher gross margins when such products are sold. The Company writes down to zero dollars the carrying value of inventory on hand that has aged over one year (two years for wafer and die bank) to cover estimated excess and obsolete exposures, unless adjustments are made based on management’s judgments for newer products, end of life products, planned inventory increases or strategic customer supply. Once established, these write-downs are considered permanent. | |
Property, Plant and Equipment, Policy | ' |
Property and Equipment | |
Property and equipment are stated at cost. Depreciation and amortization are computed using the straight-line method, based upon the shorter of the estimated useful lives ranging from two to ten years for property and equipment and from 25 to 50 years for buildings or the lease term for improvements to leased properties. | |
Goodwill and Intangible Assets, Policy | ' |
Goodwill and Purchased Intangible Assets | |
The Company tests goodwill and other indefinite-lived intangible assets for impairment on an annual basis and between annual tests if events or circumstances require an interim impairment assessment. For goodwill, the Company either makes a qualitative assessment prior to proceeding to step 1 of the annual goodwill impairment test or performs a two-step impairment test. If the Company makes a qualitative assessment and it determines that the fair value of the reporting unit is less than its carrying amount, the Company would perform step 1 of the annual goodwill impairment test and, if necessary, proceed to step 2. Otherwise, no further evaluation is necessary. For the two-step impairment test, in the first step, the Company compares the fair value of the reporting unit to its carrying value, including goodwill. The Company determines the fair value of the reporting unit based on a weighting of income and market approaches. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and no further testing is performed. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then the Company performs the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill. If the carrying value of a reporting unit’s goodwill exceeds its implied fair value, the Company records an impairment loss equal to the difference. | |
Purchased intangible assets other than goodwill are amortized over their useful lives unless these lives are determined to be indefinite. Purchased intangible assets with definite lives are carried at cost less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets, generally six months to eight years. | |
The Company has acquired in-process research and development (IPR&D) projects as the result of its business combinations (see Note 6). The fair values of the acquired IPR&D projects were determined through estimates and valuation techniques based on the terms and details of the related acquisitions. Upon completion of development for each project, the acquired IPR&D will be amortized over its useful life. The Company assesses the status of each IPR&D project quarterly to evaluate whether the carrying value has been impaired. | |
Valuation of Long-Lived Assets and Certain Identifiable Intangibles | |
The Company evaluates the recoverability of property, plant and equipment and identifiable intangible assets through the performance of periodic reviews to determine whether facts and circumstances exist that would indicate that the carrying amounts of property, plant and equipment and identifiable intangible assets exceed their fair values. If facts and circumstances indicate that the carrying amount of property, plant and equipment and identifiable intangible assets might not be fully recoverable, projected undiscounted net cash flows associated with the related asset or group of assets over their estimated remaining useful life is compared to their respective carrying amounts. In the event that the projected undiscounted cash flows are not sufficient to recover the carrying value of the assets, the assets are written down to their estimated fair values based on the expected discounted future cash flows attributable to the assets. | |
Revenue Recognition, Policy | ' |
Revenue Recognition and Accounts Receivable Allowances | |
Revenue from product sales (net of any applicable value added tax) to the Company’s direct customers is recognized upon shipment provided that persuasive evidence of a sales arrangement exists, the price is fixed or determinable, title has transferred, collection of resulting receivables is reasonably assured, there are no customer acceptance requirements and there are no remaining significant obligations. The Company makes estimates of potential future product returns and sales allowances related to current period product revenue. Management analyzes historical returns, changes in customer demand, and acceptance of products when evaluating the adequacy of sales returns and allowances. Estimates made by the Company may differ from actual product returns and sales allowances. These differences may materially impact reported revenue and amounts ultimately collected on accounts receivable. | |
A portion of the Company’s sales is made to distributors under agreements that provide the possibility of certain price adjustment credits, as discussed below, and to return qualifying products for credit, as determined by the Company, in order to reduce the amounts of slow-moving, discontinued or obsolete product from their inventory. These agreements limit such returns to a certain percentage of the value of the Company's shipments to that distributor during the prior quarter. In addition, distributors are allowed to return unsold products if the Company terminates the relationship with the distributor. | |
Certain distributors are granted price adjustment credits related to many of their sales to their customers. Price adjustment credits are granted when a distributor’s standard cost (i.e., the Company’s sales price to the distributor) does not provide the distributor with an appropriate margin on its sales to its customers. As a result, the distributor may request and receive a price adjustment credit from the Company to allow the distributor to earn an appropriate margin on the transaction. Certain distributors are also granted price adjustment credits in the event of a price decrease subsequent to the date the product was shipped and billed to the distributor. Generally, the Company will provide a credit equal to the difference between the price paid by the distributor (less any prior credits on such products) and the new price for the product multiplied by the quantity of such product in the distributor’s inventory at the time of the price decrease. Certain of the Company’s distributor arrangements may allow or require the granting of price concessions below the Company’s cost for a product. | |
Given the uncertainties associated with the levels of returns and other price adjustment credits that will be issued to these distributors, the sales price to distributors is not fixed or determinable until the distributors resell the products to their customers. Therefore, the Company defers revenue recognition from sales to these distributors until the distributors have sold the products to their end customers. | |
Title to the inventory transfers to a distributor at the time of shipment or delivery to the distributor, and payment from the distributor is due in accordance with the Company's standard payment terms. These payment terms are not contingent upon the distributors’ sale of the products to their customers. Upon title transfer to distributors, inventory is reduced for the cost of goods shipped, the deferred distributor margin (sales less cost of sales) is recorded as a liability and an account receivable is recorded. | |
The deferred costs of sales to distributors may be subject to impairment. The Company monitors the level and nature of product returns from distributors as well as the levels of inventory held at distributors. On a quarterly basis, the Company reviews the inventory held at distributors in terms of the Company’s inventory valuation policy and records a charge to cost of goods sold for all known lower of cost or market and excess and obsolescence issues. | |
Accounts Receivable Allowances Policy | ' |
In addition, the Company monitors collectibility of accounts receivable primarily through review of its accounts receivable aging. When facts and circumstances indicate the collection of specific amounts or from specific customers is at risk, the Company assesses the impact on amounts recorded for bad debts and, if necessary, will record a charge in the period such determination is made. | |
Research and Development Expense, Policy | ' |
Research and Development | |
Research and development expenditures are charged to operations as incurred. | |
Foreign Currency Transactions and Translations Policy | ' |
Foreign Currency Translation | |
The Company uses the local currency as its functional currency for all foreign subsidiaries. Translation adjustments, which result from the process of translating foreign currency financial statements into U.S. dollars, are included in the accumulated other comprehensive income component of stockholders’ equity. | |
Advertising Costs, Policy | ' |
Advertising Costs | |
The Company expenses advertising costs as incurred and includes these costs in selling, general and administrative expenses in the consolidated statement of operations. | |
Income Tax, Policy | ' |
Income Taxes | |
The Company accounts for income taxes under an asset and liability approach. Deferred income taxes reflect the impact of temporary differences between assets and liabilities recognized for financial reporting purposes and such amounts recognized for income tax reporting purposes. Valuation allowances are provided when necessary to reduce deferred tax assets to an amount that is more likely than not to be realized. Uncertain tax positions are recognized or derecognized based on the threshold and measurement of a tax position taken or expected to be taken in a tax return. U.S. income tax has not been provided on earnings of foreign subsidiaries to the extent that such earnings are considered to be indefinitely reinvested. | |
Share-based Compensation, Policy | ' |
Stock-Based Compensation | |
Stock-based compensation is measured at the grant date, based on the estimated fair value of the award. The Company amortizes the compensation costs on a straight-line basis over the requisite service period of the option, which is generally the option vesting term of four years. The Company estimates the fair value of stock options using the Black-Scholes valuation model. The Black-Scholes valuation model requires the Company to estimate key assumptions such as expected term, volatility and risk free interest rates to determine the fair value of a stock option. The estimates of these key assumptions are based on historical information and judgment regarding market factors and trends. | |
Use of Estimates, Policy | ' |
Use of Estimates | |
The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Such estimates relate to the useful lives and residual value of fixed assets, the fair value of investments, allowances for doubtful accounts and customer returns, valuation allowances for deferred tax assets, inventory write-downs, potential reserves relating to litigation matters, accrued liabilities, and other reserves. The Company bases its estimates and judgments on its historical experience, knowledge of current conditions and its beliefs of what could occur in the future, given available information. Actual results may differ from those estimates, and such difference, may be material to the financial statements. | |
Fair Value of Financial Instruments, Policy | ' |
Fair Value of Financial Instruments | |
The Company’s financial instruments consist primarily of cash and cash equivalents, marketable securities, accounts receivable and accounts payable. The Company believes that the carrying amounts of the financial instruments approximate their respective fair values. When there is no readily available market data, the Company may make fair value estimates, which may not necessarily represent the amounts that will be realized in a current or future sale of these assets. | |
Concentration Risk, Credit Risk, Policy | ' |
Concentration of Credit Risk | |
The Company operates in one business segment, which is to design, develop, and market high performance SRAM, DRAM, and other semiconductor products. The Company markets and distributes its products on a worldwide basis, primarily to original equipment manufacturers, contract manufacturers, and distributors. The Company performs ongoing credit evaluations of its customers’ financial condition and generally requires no collateral. In fiscal 2013, revenue from the Company’s largest and second largest distributor accounted for approximately 17% and 11%, respectively, of the Company's total net sales. In fiscal 2012, revenue from the Company’s largest and second largest distributor accounted for approximately 14% and 13%, respectively, of the Company's total net sales. In fiscal 2011, revenue from the Company’s largest and second largest distributor, accounted for approximately 15% and 12% of the Company's total net sales. | |
The Company maintains cash, cash equivalents, and short-term investments with various high credit quality financial institutions. The Company’s investment policy is designed to limit exposure to any one institution. The Company performs periodic evaluations of the relative credit standing of those financial institutions that are considered in its investment strategy. The Company is exposed to credit risk in the event of default by the financial institutions or issuers of investments to the extent of the amount recorded on the balance sheet. To date, the Company has not incurred losses related to these investments. | |
Product Warranty and Indemnifications Policies | ' |
Product Warranty and Indemnifications | |
The Company generally warrants its products against defects in materials and workmanship for a period of 12 months. Liability for a stated warranty period is usually limited to replacement of defective items or return of amounts paid. If there is a material increase in the rate of customer claims or the Company’s estimates of probable losses relating to specifically identified warranty exposures are inaccurate, the Company may record a charge against future cost of sales. Warranty expense has historically been immaterial to the Company’s financial statements. | |
The Company may be obligated to indemnify certain customers, distributors, suppliers, and subcontractors for attorney fees and damages and costs awarded against these parties in certain circumstances in which its products are alleged to infringe third party intellectual property rights, including patents, registered trademarks, or copyrights. The terms of the Company’s indemnification obligations are generally perpetual from the effective date of the agreement. In certain cases, there are limits on and exceptions to the Company’s potential liability for indemnification relating to intellectual property infringement claims. In addition, the Company has entered into indemnification agreements with its officers and directors, and the Company’s bylaws provide that indemnification may be provided to the Company’s agents. The Company has directors’ and officers’ insurance pursuant to which the Company may be reimbursed for certain indemnity expenses, subject to the insurers’ reservation of rights. The Company cannot estimate the amount of potential future indemnity expenses that it may be required to make. The amount of available directors’ and officers’ insurance may not be sufficient to cover the Company’s indemnity obligations, which may have a material adverse effect on the Company’s results of operations in future periods. | |

New Accounting Pronouncements, Policy | ' |
Accounting Pronouncements | |
The following issued accounting pronouncements are not yet effective for the Company as of September 30, 2013. | |
Liabilities | |
In February 2013, the Financial Accounting Standards Board (FASB) issued guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of the guidance is fixed at the reporting date. Examples of obligations include debt arrangements, other contractual obligations, and settled litigation and judicial rulings. The guidance requires an entity to measure such obligations as the sum of the amount that the reporting entity agreed to pay on the basis of its arrangement among its co-obligors in addition to amounts the reporting entity expects to pay on behalf of its co-obligors. The guidance becomes effective for the Company beginning in the first quarter of fiscal 2015 and is not expected to have a material impact on the Company's consolidated financial statements. | |
Foreign Currency Matters | |
In March 2013, FASB issued guidance on when foreign currency translation adjustments should be released to net income. When a parent entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity, the parent is required to release any related cumulative translation adjustment into net income. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The guidance becomes effective for the Company beginning in the first quarter of fiscal 2015 and is not expected to have a material impact on the Company's consolidated financial statements. | |
Accounting Standards | |
On October 1, 2012, the Company adopted the following accounting standard, which did not have a material effect on its consolidated results of operations during such period or financial condition at the end of such period: | |
Comprehensive Income | |
In June 2011, FASB amended its guidance on the presentation of comprehensive income. This amendment eliminates the currently available option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. Under this amendment, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The Company elected to present the items of net income and other comprehensive income in two separate, but consecutive statements. Effective January 1, 2013, the Company adopted the FASB's standard regarding the reporting of reclassifications out of accumulated other comprehensive income. The new standard requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. | |
Reclassification, Policy | ' |
Reclassifications | |
Certain reclassifications have been made to prior year balances in order to conform to the current year’s presentation. |
