Basis of Presentation | |
The accompanying unaudited condensed consolidated financial statements include the accounts of Integrated Silicon Solution, Inc. (the Company or ISSI) and its consolidated majority owned subsidiaries, after elimination of all significant intercompany accounts and transactions. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim financial information and with Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (which are of a normal, recurring nature) considered necessary for fair presentation have been included. | |
On September 14, 2012, the Company acquired approximately 94.1% of the outstanding shares of Chingis Technology Corporation (Chingis) and the Company’s financial results reflect accounting for Chingis on a consolidated basis from the date of acquisition. In May 2013, the Company acquired an additional 4.8% of Chingis for approximately $1.6 million. In October 2013, the Company acquired an additional 0.5% of Chingis for approximately $0.2 million. At March 31, 2014, the Company owned approximately 99.4% of the outstanding shares of Chingis. | |
The Company’s operating results for the six months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2014 or for any other period. The financial statements included herein should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2013. | |

Use of Estimates | ' |
Use of Estimates | |
The preparation of financial statements in conformity with U.S. GAAP 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 include the useful lives of fixed assets, 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 differences may be material to the financial statements. |

Impact of Recently Issued Accounting Pronouncements and Standards | |
The following issued accounting pronouncements are not yet effective for the Company as of March 31, 2014. | |
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. |

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 March 31, 2014, the Company’s financial assets utilizing Level 1 inputs included investment securities traded on an active securities exchange. The Company did not have any financial assets utilizing Level 2 or Level 3 inputs at March 31, 2014 or September 30, 2013. | |||||||||||||||||

Stock-Based Benefit Plans | |||||||||||||||||
The Company grants stock-based compensation awards under its 2007 Incentive Compensation Plan (the 2007 Plan) which permits the grant of stock options, stock appreciation rights (SARs), restricted stock awards, restricted stock units (RSUs), performance shares and performance units. The Company has outstanding grants under its 2012 Inducement Option Plan (the Inducement Plan) and under prior plans, though no further grants can be made under these plans. At March 31, 2014, 1,744,000 shares were available for future grant under the 2007 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. 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. | |||||||||||||||||
The Company began granting cash-settled SARs in the first quarter of fiscal 2014. The SARs vest ratably over a four-year period with a 6-month or 1-year cliff vest and then vest ratably each month over the remaining period based upon continued employment with the Company. The SARs expire seven years after the date of grant. These SARs allow the holder to receive in cash the difference between the SARs' exercise price (which is the closing market price of the Company's common stock on the grant date) and the closing market price of the Company's common stock on the date the holder exercises the SAR. The SARs are recorded as a liability in accrued compensation and benefits in the Company's balance sheet. | |||||||||||||||||
The Company has an Employee Stock Purchase Plan (ESPP) which permits eligible employees to purchase shares of the Company’s common stock through payroll deductions. As approved by the Board of Directors, effective August 1, 2010, shares under the ESPP are 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 offering period. The offering periods under the ESPP commence on approximately February 1 and August 1 of each year. At March 31, 2014, 453,000 shares were available for future issuance under the ESPP. | |||||||||||||||||

As of March 31, 2014, there was approximately $10.6 million of total unrecognized stock-based compensation expense related to options and awards under the Company’s stock-based benefit plans that will be recognized over a weighted-average period of approximately 2.68 years. Future stock option and award grants will add to this total whereas quarterly amortization and the vesting of the existing stock option and award grants will reduce this total. In addition, as of March 31, 2014, there was approximately $200,000 of total unrecognized stock-based compensation expense under the Company’s ESPP that will be recognized over a weighted-average period of approximately four months. As of March 31, 2014, there was approximately $5.6 million of total unrecognized stock-based compensation expense related to SARs that will be recognized over a weighted-average period of approximately 3.61 years. Future SAR grants will add to this total whereas quarterly amortization and the vesting of the SARs will reduce this total. In addition, because the SARs are settled with cash, the fair value of the SARs must be revalued on a quarterly basis which will likely impact the amount of expense in future periods. | |||||||||||||||||
The Company uses the Black-Scholes option pricing model to estimate the fair value of the options and SARS granted and rights to acquire stock granted under the ESPP. The weighted average estimated fair values of stock option grants and rights granted under the ESPP, as well as the weighted average assumptions used in calculating these values during the three and six month periods ended March 31, 2014 and 2013 were based on estimates at the date of grant as follows: | |||||||||||||||||

Income Taxes | |
The income tax provision includes U.S. federal, state and local, and foreign income taxes and is based on the application of a forecasted annual income tax rate applied to the current quarter's year-to-date pre-tax income for fiscal 2014. In determining the estimated annual effective income tax rate, the Company analyzes various factors, including projections of the Company's annual earnings, taxing jurisdictions in which the earnings will be generated, the impact of state and local income taxes, the Company's ability to use tax credits and net operating loss carryforwards, and available tax planning alternatives. Discrete items, including the effect of changes in tax laws, tax rates, and certain circumstances with respect to valuation allowances or other unusual or non-recurring tax adjustments are reflected in the period in which they occur as an addition to, or reduction from, the income tax provision, rather than being included in the estimated annual effective income tax rate. | |
For the three and six months ended March 31, 2014, the Company recorded income tax expense of $2.9 million and 4.6 million, respectively, that represents an effective tax rate of approximately 25% and 24%, respectively. The differences between the recorded provision for income taxes and the tax provision, based on the federal statutory rate of 35%, were primarily attributable to the differential in foreign tax rates and non-deductible stock-based compensation expense. | |
For the three and six months ended March 31, 2013, the Company recorded income tax expense of $3.2 million and $4.4 million, respectively, that represents an effective tax rate of approximately 50% and 43%, respectively. A discrete item was recorded in the three months and six months ended March 31, 2013 related to an increase in the valuation allowance of approximately $1.4 million for California net operating loss carryforwards based on the Company's estimated inability to use these carryforwards in the future as a result of a change in the Company's legal structure. The differences between the recorded provision for income taxes and the tax provision, based on the federal statutory rate of 35%, were primarily attributable to the impact of this discrete item, the differential in foreign tax rates and non-deductible stock-based compensation expense. | |
As of March 31, 2014, the Company had unrecognized tax positions that would impact its effective tax rate, if realized. |

In the six month period ended March 31, 2014, the Company did not repurchase any shares of its common stock in the open market. As of March 31, 2014, 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 March 31, 2014, $19.8 million remained available under the Company's existing share repurchase authorization. | |
The Company issues RSUs as part of its equity incentive plan. 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 the six months ended March 31, 2014, the Company withheld 30,323 shares to satisfy approximately $0.4 million of employee 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. |

Legal Matters | |
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. | |
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. On April 18, 2014, the Court granted the motion in part and denied the motion in part. Specifically, the Court granted the Company's motion to dismiss as to GSI’s causes of action for violation of the Sherman Act, violation of the Racketeering Influenced and Corrupt Organizations Act, and intentional interference with contract. The Company expects to answer the non-dismissed portions of the complaint on June 2, 2014. The Court has also scheduled a case management conference for June 10, 2014. The Company believes it has meritorious defenses to the claims alleged by GSI and intends to defend this suit vigorously. However, there can be no assurance as to the outcome of this matter or any future litigation. | |
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. | |
Commitments to Wafer Fabrication Facilities and Contract Manufacturers | |
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 at the foundry, as a matter of practice, it becomes increasingly difficult to cancel the purchase order. As of March 31, 2014, the Company had approximately $35.0 million of purchase orders for which the related wafers had been entered into wafer work-in-process (i.e., manufacturing had begun). |

Basis of Presentation | |
The accompanying unaudited condensed consolidated financial statements include the accounts of Integrated Silicon Solution, Inc. (the Company or ISSI) and its consolidated majority owned subsidiaries, after elimination of all significant intercompany accounts and transactions. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim financial information and with Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (which are of a normal, recurring nature) considered necessary for fair presentation have been included. | |
Accounting Pronouncements | ' |
The following issued accounting pronouncements are not yet effective for the Company as of March 31, 2014. | |
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. |
