| SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | Business Description We are a leading provider of machine to machine (M2M) networking products and end-to-end solutions that enable the connection, monitoring and control of local or remote physical assets by electronic means. Our products are deployed by a wide range of businesses and institutions. We focus a significant amount of our development, sales and marketing efforts on continuing to develop, manufacture and market a wide range of hardware products that have been the historical backbone of our business since its inception; and expand and enhance our deployment of software applications and cloud-based platform solutions that enable electronic devices to interface with business applications. Principles of Consolidation The consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Cash Equivalents Cash equivalents consist of money market accounts and other highly liquid investments purchased with an original maturity of three months or less. The carrying amounts approximate fair value due to the short maturities of these investments. Marketable Securities Marketable securities consist of certificates of deposit, commercial paper, corporate bonds and government municipal bonds. All marketable securities are accounted for as available-for-sale and are carried at fair value with unrealized gains and losses reported as a separate component of stockholders' equity. We obtain quoted market prices and trading activity for each security, where available, review the financial solvency of each security issuer and obtain other relevant information to estimate the fair value for each security in our investment portfolio. We regularly monitor and evaluate the value of our marketable securities. When assessing marketable securities for other-than-temporary declines in value, we consider several factors. These factors include: how significant the decline in value is as a percentage of the original cost, how long the market value of the investment has been less than its original cost, the underlying factors contributing to a decline in the prices of securities in a single asset class, the performance of the issuer's stock price in relation to the stock price of its competitors within the industry, expected market volatility, analyst recommendations, the views of external investment managers, any news or financial information that has been released specific to the investee and the outlook for the overall industry in which the issuer operates. If events and circumstances indicate that a decline in the value of a security has occurred and is other-than-temporary, we would record a charge to other income (expense). Accounts Receivable Accounts receivable are stated at the amount we expect to collect, which is net of an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. The following factors are considered when determining the collectability of specific customer accounts: customer creditworthiness, past transaction history with the customer, and changes in customer payment terms or practices. In addition, overall historical collection experience, current economic industry trends, and a review of the current status of trade accounts receivable are considered when determining the required allowance for doubtful accounts. Based on our assessment, we provide for estimated uncollectible amounts through a charge to earnings and a credit to our allowance for doubtful accounts. Balances that remain outstanding after we have used reasonable collection efforts are written off through a charge to the allowance for doubtful accounts and a credit to accounts receivable. Inventories Inventories are stated at the lower of cost or fair market value, with cost determined using the first-in, first-out method. Appropriate consideration is given to deterioration, obsolescence and other factors in evaluating fair market value. Property, Equipment and Improvements, Net Property, equipment and improvements are carried at cost, net of accumulated depreciation. Depreciation is provided by charges to operations using the straight-line method over the estimated asset useful lives. Furniture and fixtures and other 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) equipment are depreciated over a period of three to seven years. Building improvements and buildings are depreciated over ten and thirty-nine years, respectively. Equipment under capital lease is depreciated over the lesser of the lease term or its depreciable life. Expenditures for maintenance and repairs are charged to operations as incurred, while major renewals and betterments are capitalized. The assets and related accumulated depreciation accounts are adjusted for asset retirements and disposals with the resulting gain or loss included in operations. Identifiable Intangible Assets Purchased proven technology, license agreements, covenants not to compete and other identifiable intangible assets are recorded at fair value when acquired in a business acquisition, or at cost when not purchased in a business acquisition. Purchased in-process research and development costs (IPR&D) related to business combinations are capitalized and amortized once it is placed in service. All other identifiable intangible assets are amortized on either a straight-line basis over their estimated useful lives of three to thirteen years or based on the pattern in which the asset is consumed. Useful lives for identifiable intangible assets are estimated at the time of acquisition based on the periods of time from which we expect to derive benefits from the identifiable intangible assets. Amortization of purchased and core technology is presented as a separate component of cost of sales in the Consolidated Statements of Operations. Amortization of all other acquired identifiable intangible assets is charged to operating expense as a component of general and administrative expense. Identifiable intangible assets are reviewed for impairment annually or whenever events or circumstances indicate that undiscounted expected future cash flows are not sufficient to recover the carrying value amount. We measure impairment loss by utilizing an undiscounted cash flow valuation technique using fair values indicated by the income approach. Impairment losses, if any, would be recorded in the period the impairment is identified. No impairments were identified during fiscal years 2012, 2011 or 2010. Goodwill Goodwill represents the excess of cost over the fair value of identifiable assets acquired. Goodwill is tested for impairment on an annual basis as of June 30, or more frequently if events or circumstances occur which could indicate impairment. As of June 30, 2012, our market capitalization was $264.3 million compared to our carrying value of $265.7 million. Our market capitalization plus our estimated control premium of 40% resulted in a fair value in excess of our carrying value by a margin of 39% and therefore no impairment was indicated. At September 30, 2012, our market capitalization was $263.3 million compared to our carrying value of $270.9 million. Since there were no triggering events through September 30, 2012, and our market capitalization plus our estimated control premium of 40% resulted in a fair value in excess of our carrying value by a margin of 36%, no impairment was indicated. The control premium used in our annual goodwill assessment at June 30, 2012 and our further evaluation of goodwill at September 30, 2012 was based on a recent control premium study as of June 30, 2012, resulting in a range of control premium of 30% to 45%. We concluded that a 40% control premium best represented the amount an investor would pay, over and above market capitalization, in order to obtain a controlling interest given the economic conditions at that time. In order to compute the above control premium, three methodologies were used, including (1) analyzing individual transactions within our industry, (2) analyzing industry-wide data, and (3) analyzing global transaction data. Individual transactions in the Communication Equipment or Computer & Peripherals industries were used to find transactions of target companies that operated in similar markets and shared similar operating characteristics with Digi. Transaction screening criteria included selection of transactions with the following characteristics: •At least 50 percent of a target company's equity sought by an acquirer, •Target company considered operating (not in bankruptcy), •Target company had publicly traded stock outstanding at the transaction date, and
In analyzing industry-wide data, transactions in three industries were identified that encompassed the products offered by us: Office Equipment and Computer Hardware, Communications, and Computer, Supplies and Services. Finally, control premiums were considered for both domestic and international transactions. 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) At June 30, 2011, our market capitalization exceeded the carrying value of our reporting unit by 28.6%; therefore, there was no indication of goodwill impairment. We have defined the criteria that will result in additional interim goodwill impairment testing. If these criteria are met, we will undertake an analysis to determine whether a goodwill impairment has occurred, which could have a material effect on our consolidated financial position and results of operations. The evaluation of asset impairment may require us to make assumptions about future cash flows and revenues. These assumptions require significant judgment and actual results may differ from assumed or estimated amounts. If these estimates and assumptions change, we may be required to recognize impairment losses in the future. There have been no goodwill impairment losses since the adoption of Accounting Standards Codification (ASC) 350 Intangibles-Goodwill and Others in fiscal 2003. Revenue Recognition We recognize revenue in accordance with authoritative guidance issued by FASB related to revenue recognition. Revenue recognized for product sales was 95.5%, 95.5% and 96.7% of net sales in fiscal 2012, 2011 and 2010, respectively. We recognize product revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, collectability is reasonably assured and there are no post-delivery obligations, other than warranty. Under these criteria, product revenue generally is recognized upon shipment of product to customers, including Direct (end-user) / OEMs and distributors. Sales to authorized domestic distributors and Direct / OEMs are made with certain rights of return and price adjustment provisions. Estimated reserves for future returns and pricing adjustments are established by us based on an analysis of historical patterns of returns and price adjustments as well as an analysis of authorized returns compared to received returns, current on-hand inventory at distributors, and distribution sales for the current period. Estimated reserves for future returns and price adjustments are charged against revenues in the same period as the corresponding sales are recorded. Our non-product revenue represented 4.5%, 4.5% and 3.3% of net sales in fiscal 2012, 2011 and 2010, respectively. The majority of the non-product revenue was from professional and engineering services and represented 4.1%, 4.2% and 2.9% of net sales in fiscal 2012, 2011 and 2010, respectively. We also had revenue from cloud-based services, post-contract customer support, fees associated with technical support, training, royalties and the sale of software licenses. Our software development tools and development boards often include multiple elements, including hardware, software licenses, post-contract customer support, limited training and basic hardware design review. Our customers purchase these products and services during their product development process in which they use the tools to build network connectivity into the devices they are manufacturing. Revenue for professional and engineering services and training is recognized upon performance. Revenue from software licenses is recognized when earned. Revenues from contracts with multiple element arrangements are recognized as each element is earned based on the relative fair value of each element provided the delivered elements have value to customers on a standalone basis. Amounts allocated to each element are based on its vendor specific objective evidence, such as the sales price for the product or service when it is sold separately. Revenue from cloud-based services is earned in two ways: a) web-based management fees are considered to be earned on a monthly basis consistent with a monthly contractual commitment, and b) transaction fees that are billed to the customer at the larger of the minimum price or the number of transactions times the stated fee and are considered earned as the transactions occur. Research and Development Research and development costs are expensed when incurred. Research and development costs include compensation, allocation of corporate costs, depreciation, utilities, professional services and prototypes. Software development costs are expensed as incurred until the point that technological feasibility and proven marketability of the product are established. To date, the time period between the establishment of technological feasibility and completion of software development has been short, and no significant development costs have been incurred during that period. Accordingly, we have not capitalized any software development costs to date. Income Taxes Deferred income taxes are recognized for the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts at each year end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Income tax expense is equal to the tax payable for the period and the change during the period in deferred tax assets and liabilities and also changes in income tax reserves. 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Net Income Per Common Share Basic net income per common share is calculated based on the weighted average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the weighted average number of common and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares of our stock result from dilutive common stock options and shares purchased through our employee stock purchase plan. The following table is a reconciliation of the numerators and denominators in the net income per common share calculations (in thousands, except per common share data):
We use the treasury stock method to calculate the weighted-average shares used in the diluted earnings per share computation. Under the treasury stock method, the proceeds from exercise of an option, the amount of compensation cost, if any, for future service that we have not yet recognized, and the amount of estimated tax benefits that would be recorded in paid-in capital, if any, when the option is exercised are assumed to be used to repurchase shares in the current period. Because their effect would be anti-dilutive at period end, certain potentially dilutive shares related to stock options to purchase common shares were not included in the above computation of diluted earnings per share because the options' exercise prices were greater than the average market price of our common shares. At September 30, 2012, 2011 and 2010, potentially dilutive shares related to such stock options were 2,023,213, 1,831,713 and 2,493,261, respectively. Stock-Based Compensation Stock-based compensation expense represents the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. This cost must be recognized over the period during which an employee is required to provide the service (usually the vesting period). Foreign Currency Translation Financial position and results of operations of our international subsidiaries are measured using local currencies as the functional currency, except for our Singapore location which uses the U.S. Dollar as its local currency. Assets and liabilities of these operations are translated at the exchange rates in effect at the end of each reporting period. Statements of operations accounts are translated at the weighted average rates of exchange prevailing during each reporting period. Translation adjustments arising from the use of differing currency exchange rates from period to period are included in accumulated other comprehensive income (loss) in stockholders' equity. Gains and losses on foreign currency exchange transactions, as well as translation gains or losses on transactions denominated in currencies other than an entity's functional currency are reflected in the statement of operations. During fiscal 2012, 2011 and 2010 there were net transaction gains (losses) of $(0.4) million, $(0.7) million and $0.3 million, respectively that were recorded in other income (expense). We have not implemented a formal hedging strategy, although we employ natural hedging of assets and liabilities denominated in foreign currencies to reduce our foreign currency risk. Use of Estimates and Risks and Uncertainties The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates that could significantly affect our results of operations or financial condition involve the assignment of fair values upon acquisition of goodwill and other intangible assets and testing for impairment; the determination of our allowance for doubtful accounts and reserve for future returns and pricing adjustments; the estimation of our inventory obsolescence, warranty reserve, income tax reserves and other contingencies. Comprehensive Income (Loss) Our comprehensive income (loss) is comprised of net income, foreign currency translation adjustments and unrealized gains and losses on available-for-sale marketable securities, which are charged or credited to the accumulated other comprehensive income (loss) account in stockholders' equity. Recent Accounting Developments In August 2012, the U.S. Securities and Exchange Commission (the “SEC”) adopted a rule mandated by the Dodd-Frank Act to require companies to publicly disclose their use of conflict minerals that originated in the Democratic Republic of the Congo or an adjoining country. The final rule applies to a company that uses minerals including tantalum, tin, gold or tungsten. The final rule requires companies to provide disclosure on a new form filed with the SEC, with the first specialized disclosure report due on May 31, 2014, for the 2013 calendar year, and annually on May 31 each year thereafter. We are currently evaluating the impact of adoption. In July 2012, the Financial Accounting Standards Board (“FASB”) issued ASU 2012-02, "Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment." The FASB amended its guidance on testing of indefinite-lived intangible assets for impairment. Under the amended guidance, companies may perform a qualitative assessment to determine whether further impairment testing is necessary, similar to the amended goodwill impairment testing guidance noted below. The guidance for indefinite-lived intangible assets is effective for annual and interim tests performed for fiscal years beginning after September 15, 2012, with an option for early adoption. We will adopt ASU 2012-02 effective for our fiscal year beginning October 1, 2012 and do not expect this pronouncement to have a material effect on our consolidated financial statements. In September 2011, the FASB issued Accounting Standards Update (“ASU”) No. 2011-08, “Intangibles-Goodwill and Other (Topic 350) Testing Goodwill for Impairment”. This guidance provides an update on how an entity tests goodwill for impairment. This revised guidance allows companies an option to make a qualitative evaluation about the likelihood of goodwill impairment. Under the revised guidance, a company is permitted to first assess qualitative factors to determine whether goodwill impairment exists prior to performing analysis comparing the fair value of a reporting unit to its carrying amount. If, based on the qualitative assessment, a company concludes it is more likely than not that the fair value of the reporting unit exceeds its carrying value, then quantitative testing for impairment is not necessary. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We, however, adopted this update early so it was effective for our fiscal year beginning October 1, 2011 (see Note 7 to the Condensed Consolidated Financial Statements). This guidance had no impact on our consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income”. This guidance eliminates the option to report other comprehensive income and its components in the consolidated statement of stockholders' equity. Rather it requires that all non-owner changes in stockholders' equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. This guidance also requires us to present on the face of the financial statements any reclassification adjustments for items that are reclassified from other comprehensive income to net income. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We will adopt this guidance beginning with our fiscal quarter ending December 31, 2012. The adoption of this guidance is not expected to have any effect on our consolidated financial position or results of operations, as it will only impact how certain information related to other comprehensive income is presented in our consolidated financial statements. In December 2011, FASB issued ASU No. 2011-12 which amends this guidance and defers only the presentation of reclassification of items out of accumulated comprehensive income. No other requirements of ASU No. 2011-05 are affected by this deferral. 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) In May 2011, the FASB issued ASU No. 2011-04, “Fair Value Measurements (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs”. This guidance updates many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements to ensure consistency between U.S. GAAP and International Financial Reporting Standards (“IFRS”). This guidance is to be applied prospectively and is effective during interim and annual periods beginning after December 15, 2011. We adopted this guidance beginning with our fiscal quarter ending March 31, 2012. This guidance had no impact on our consolidated financial statements. |

| MARKETABLE SECURITIES | MARKETABLE SECURITIES Our marketable securities consist of certificates of deposit, commercial paper, corporate bonds and government municipal bonds. We analyze our available-for-sale marketable securities for impairment on an ongoing basis. When we perform this analysis, we consider factors such as the length of time and extent to which the securities have been in an unrealized loss position and the trend of any unrealized losses. We also consider whether an unrealized loss is a temporary loss or an other-than-temporary loss such as: (a) whether we have the intent to sell the security, or (b) whether it is more likely than not that we will be required to sell the security before its anticipated recovery, or (c) permanent impairment due to bankruptcy or insolvency. In order to estimate the fair value for each security in our investment portfolio, where available, we obtain quoted market prices and trading activity for each security. We also review the financial solvency of each security issuer and obtain other relevant information from our investment advisor. As of September 30, 2012, 42 of our 62 securities that we are holding were trading below our amortized cost basis. We determined each decline in value to be temporary based upon the above described factors. We expect to realize the fair value of these securities, plus accrued interest, either at the time of maturity or when the security is sold. All of our current holdings are classified as available-for-sale marketable securities and are recorded at fair value on our consolidated balance sheet with the unrealized gains and losses recorded in accumulated other comprehensive loss. All of our non-current marketable securities will mature in less than 15 months. 6. MARKETABLE SECURITIES (CONTINUED) At September 30, 2012 our marketable securities were (in thousands):

| FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. This standard also establishes a hierarchy for inputs used in measuring fair value. This standard 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 market participants would use in valuing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability based upon the best information available in the circumstances. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is broken down into the following three levels:
7. FAIR VALUE MEASUREMENTS (CONTINUED)
Fair value is applied to financial assets such as our marketable securities, which are classified and accounted for as available-for-sale. These items are stated at fair value at each reporting period using the above guidance. The following tables provide information by level for financial assets that are measured at fair value on a recurring basis (in thousands):
Cash equivalents are measured at fair value using quoted market prices in active markets for identical assets and are therefore classified as Level 1 assets. We value our Level 2 assets using inputs that are based on market indices of similar assets within an active market. There were no transfers in to or out of our Level 2 financial assets during the twelve months ended September 30, 2012. 7. FAIR VALUE MEASUREMENTS (CONTINUED) We had no financial assets valued with Level 3 inputs as of September 30, 2012 nor did we purchase or sell any Level 3 financial assets during the twelve months ended September 30, 2012. The use of different assumptions, applying different judgment to matters that are inherently subjective and changes in future market conditions could result in different estimates of fair value of our securities, currently and in the future. If market conditions deteriorate, we may incur impairment charges for securities in our investment portfolio. |

| RESTRUCTURING | RESTRUCTURING 2012 Restructuring On April 26, 2012, we announced our intention to restructure certain of our operations. The restructuring relates primarily to changes being implemented to focus on a shift in our business to more aggressively sell end-to-end M2M solutions. As a result of this restructuring, we eliminated employment positions in our work force and have moved to hire new employees or re-assign existing employees into newly created positions. We recorded $1.0 million of restructuring charges on a pre-tax basis. These charges were incurred in connection with reductions in force of 30 employees and represented severance of $0.6 million and expenses from vacating facilities in Davis, California and Huntington Beach, California of approximately $0.4 million. The payments associated with these charges and all the actions associated with the restructuring are expected to be completed by the second quarter of fiscal 2013. Below is listed a summary of the restructuring charges and other activity within the restructuring accrual (in thousands):
2011 Restructuring On July 21, 2011, we announced a restructuring of our manufacturing operations in Breisach, Germany. The restructuring reduced our manufacturing footprint by consolidating prototype and production functions and centralizing outsourced 9. RESTRUCTURING (CONTINUED) production control in our Eden Prairie, Minnesota production facility. The consolidation was driven by our strategy of driving efficiency improvements and enhancing customer service globally through more centralized operations. We ceased manufacturing in Breisach at the end of December 2011 however, we continue to maintain sales and research and development activities at the leased facility in Breisach, Germany.

| INCOME TAXES | INCOME TAXES The components of income before income taxes are as follows (in thousands):
The components of the income tax provision are as follows (in thousands):
10. INCOME TAXES (CONTINUED) The net deferred tax asset consists of the following (in thousands):
As of September 30, 2012, we have tax credit carryforwards in a foreign jurisdiction of $0.2 million, the majority of which will expire in 2015. We have generally concluded that it is more likely than not that our deferred tax assets will be realized based on future projected taxable income and the anticipated future reversal of deferred tax liabilities. Our valuation allowance for certain foreign locations at September 30, 2012 and 2011 was $0.5 million and $0.4 million, respectively. The amount of the deferred tax assets actually realized could vary if there are differences in the timing or amount of future reversals of existing deferred tax liabilities or changes in the amounts of future taxable income. If our future taxable income projections are not realized, an additional valuation allowance may be required, and would be reflected as income tax expense at the time that any such change in future taxable income is determined. The reconciliation of the statutory federal income tax rate to our effective income tax rate is as follows:
10. INCOME TAXES (CONTINUED) During fiscal 2012, we recorded a discrete tax benefit of $1.5 million, related to additional research and development tax credits identified for fiscal years ended September 30, 2009, 2010 and 2011, reversal of tax reserves for closure of various jurisdictions' tax matters and tax rate reductions in foreign jurisdictions. These discrete tax benefits reduced our effective tax rate by 14.1 percentage points for the twelve month period ended September 30, 2012 to 30.1%. During fiscal 2012, the income tax provision before discrete tax benefits was higher than the statutory rate primarily due to an increase in certain reserves for unrecognized tax benefits, an adjustment for foreign income taxed at the U.S. rate, and a reduction in domestic tax benefits compared to a year ago. During fiscal 2011, we recorded a discrete tax benefit of $0.7 million. This benefit primarily resulted from the reversal of tax reserves from various jurisdictions, primarily foreign, related to the expiration of the statutes of limitations. It also resulted from the enactment of the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 extending the research and development tax credit that allowed us to record tax credits earned during the last three quarters of fiscal 2010 in the first quarter of fiscal 2011. This benefit reduced our effective tax rate by 4.4 percentage points for the twelve month period ended September 30, 2011 to 33.3%. During fiscal 2010, we reversed $2.3 million in income tax reserves associated primarily with the closing of prior tax years through statute expiration and the conclusion of a federal tax audit. While the statutes of limitations have not expired, U.S. federal income tax returns for the periods ended September 30, 2007 and September 30, 2008 have been audited by and settled with the Internal Revenue Service. The aforementioned income tax benefits resulting from the reversal of income tax reserves and other discrete tax benefits reduced the effective tax rate by 22.4 percentage points in fiscal 2010. A reconciliation of the beginning and ending amount of unrecognized tax benefits is (in thousands):
The total amount of unrecognized tax benefits that, if recognized, would affect our effective tax rate is $2.7 million. We expect that it is reasonably possible that the total amounts of unrecognized tax benefits will decrease approximately between $0.3 million to $0.4 million over the next 12 months due to the expiration of statue of limitations. We recognize interest and penalties related to income tax matters in income tax expense. During the fiscal years ended September 30, 2012, 2011 and 2010, there were insignificant amounts of interest and penalties related to income tax matters in income tax expense. We had accrued interest and penalties related to unrecognized tax benefits as of both September 30, 2012 and September 30, 2011, of $0.6 million. Our long-term income taxes payable on our condensed consolidated balance sheets includes these accrued interest and penalties in addition to the unrecognized tax benefits in the table above. We operate in multiple tax jurisdictions both in the U.S. and outside of the U.S. Accordingly, we must determine the appropriate allocation of income to each of these jurisdictions. This determination requires us to make several estimates and assumptions. Tax audits associated with the allocation of this income, and other complex issues, may require an extended period of time to resolve and may result in adjustments to our income tax balances in those years that are material to our consolidated balance sheet and results of operations. We are no longer subject to income tax examination for tax years prior to fiscal 2009 in the case of U.S. federal tax authorities and prior to fiscal 2008 for non-U.S. income tax authorities. For state taxing authorities, consisting primarily of Minnesota and California, we are no longer subject to income tax examination for tax years generally before fiscal 2008. 10. INCOME TAXES (CONTINUED) At September 30, 2012, we had approximately $22.0 million of accumulated undistributed foreign earnings, for which we have not accrued additional U.S. tax. Our policy is to reinvest earnings of our foreign subsidiaries indefinitely to fund current operations and provide for future international expansion opportunities, and only repatriate earnings to the extent that U.S. taxes have already been recorded. Although we have no current need to do so, if we change our unremitted assertion to repatriate additional undistributed foreign earnings for cash requirements in the United States, we would have to accrue applicable taxes. The amount of any taxes and the application of any tax credits would be determined based on the income tax laws at the time of such repatriation. Under current tax laws, we estimate the unrecognized deferred tax liability to be in the range of $2.5 million to $3.5 million and could have a material impact on our current consolidated balance sheet, results of operations and cash flows. |

| STOCK-BASED COMPENSATION | STOCK-BASED COMPENSATION Stock-based awards are granted under the terms of the 2000 Omnibus Stock Plan as amended and restated as of December 4, 2009 (the Omnibus Plan), as well as our Stock Option Plan as amended and restated as of November 27, 2006 (the Stock Option Plan) and Non-Officer Stock Option Plan as amended and restated as of November 27, 2006 (the Non-Officer Plan), both of which expired during the first quarter of fiscal 2007 (the Plans). Additional awards cannot be made under the Stock Option Plan or the Non-Officer Plan. The authority to grant options under the Omnibus Plan and set other terms and conditions rests with the Compensation Committee of the Board of Directors. The Stock Option Plan and the Non-Officer Plan include non-statutory stock options (NSOs) and the Stock Option Plan also includes incentive stock options (ISOs) to employees and others who provide services to us, including consultants, advisers and directors. Options granted under these plans generally vest over a four year service period and will expire if unexercised after ten years from the date of grant. Share awards vest upon continued employment. The exercise price for ISOs and non-employee director options granted under the Stock Option Plan was set at the fair market value of our common stock based on the closing price on the date of grant. The exercise price for NSOs granted under the Stock Option Plan or the Non-Officer Plan was set by the Compensation Committee of the Board of Directors and was set to the exercise price based on the closing price on the date of grant. The Omnibus Plan authorizes the issuance of up to 5,750,000 common shares in connection with awards of stock options, stock appreciation rights, restricted stock, performance units or stock awards. Eligible participants include our employees, non-employee directors, consultants and advisors. Awards may be granted under the Omnibus Plan until December 4, 2019 as an authorization to issue an additional 2,500,000 common shares was ratified on January 25, 2010 at the Annual Meeting of Stockholders. Options under the Omnibus Plan can be granted as either ISOs or NSOs. The exercise price shall be determined by our Compensation Committee but shall not be less than the fair market value of our common stock based on the closing price on the date of grant. We recorded cash received from the exercise of stock options of $1.1 million, $2.9 million and $1.7 million during fiscal years 2012, 2011 and 2010, respectively. The excess tax benefits from stock-based compensation were $0.2 million during fiscal 2012, $0.8 million during fiscal 2011 and immaterial during fiscal year 2010. Upon exercise, we issue new shares of stock. The Plans have provisions allowing employees to elect to pay their withholding obligation through share reduction. No employees elected to pay income tax withholding obligations through share reduction during fiscal years 2012, 2011 and 2010. Also, we sponsor an Employee Stock Purchase Plan as amended and restated as of December 4, 2009 and November 27, 2006 (the Purchase Plan), covering all domestic employees with at least 90 days of continuous service and who are customarily employed at least 20 hours per week. The Purchase Plan allows eligible participants the right to purchase common stock on a quarterly basis at the lower of 85% of the market price at the beginning or end of each three-month offering period. The Purchase Plan was ratified on January 25, 2010 at the Annual Meeting of Stockholders to increase the number of shares reserved for future purchases to the Purchase Plan by 250,000 shares bringing the total number of shares to 2,000,000 shares of our Common Stock that may be purchased under the plan. Employee contributions to the Purchase Plan were $1.0 million in the fiscal 2012, $1.0 million in fiscal 2011 and $0.9 million in fiscal year 2010. Pursuant to the Purchase Plan, 115,477, 112,285, and 124,087 common shares were issued to employees during the fiscal years ended 2012, 2011 and 2010, respectively. Shares are issued under the Purchase Plan from treasury stock. As of September 30, 2012, 199,680 common shares were available for future issuances under the Purchase Plan. 11. STOCK-BASED COMPENSATION (CONTINUED) Stock-based compensation expense is included in the consolidated results of operations as follows (in thousands):
Stock-based compensation cost capitalized as part of inventory was immaterial as of September 30, 2012, 2011 and 2010. A summary of options and common shares reserved for grant under the Plans and Assumed Plans are as follows (in thousands, except per common share amounts):
(1) The aggregate intrinsic value represents the total pre-tax intrinsic value, based on our closing stock price of $10.16 as of September 30, 2012, which would have been received by the option holders had all option holders exercised their options as of that date. The intrinsic value of an option is the amount by which the fair value of the underlying stock exceeds its exercise price. The total intrinsic value of all options exercised during each of the twelve months ended September 30, 2012, 2011 and 2010 was $0.7 million, $2.4 million and $0.6 million, respectively. The table below shows the weighted average fair value, which was determined based upon the fair value of each option on the grant date utilizing the Black-Scholes option-pricing model and the related assumptions:
The fair value of each option award granted during the periods presented was estimated using the Black-Scholes option valuation model that uses the assumptions noted in the table above. Expected volatilities are based on the historical volatility of 11. STOCK-BASED COMPENSATION (CONTINUED our stock. We use historical data to estimate option exercise and employee termination information within the valuation model; separate groups of grantees that have similar historical exercise behaviors are considered separately for valuation purposes. The expected term of options granted is derived from the vesting period and historical information and represents the period of time that options granted are expected to be outstanding. The risk-free rate used is the zero-coupon U.S. Treasury bond rate in effect at the time of the grant whose maturity equals the expected term of the option. A summary of our non-vested options as of September 30, 2012 and changes during the twelve months then ended is presented below (in thousands, except per common share amounts):
We use historical data to estimate pre-vesting forfeiture rates. The pre-vesting forfeiture rate used in fiscal 2012 was 2.0%. As of September 30, 2012 the total unrecognized compensation cost related to non-vested stock-based compensation arrangements, net of expected forfeitures, was $6.1 million and the related weighted average period over which it is expected to be recognized is approximately 2.5 years. At September 30, 2012, the weighted average exercise price and remaining life of the stock options are as follows (in thousands, except remaining life and exercise price):
The total grant date fair value of shares vested was $3.0 million in fiscal 2012, $3.7 million in fiscal 2011 and $2.9 million in fiscal 2010. |

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.

| CONTINGENCIES | CONTINGENCIES Inital Public Offering Securities Litigation On April 19, 2002, a consolidated amended class action complaint was filed in the United States District Court for the Southern District of New York asserting claims relating to the initial public offering (“IPO”) of our subsidiary NetSilicon, Inc. and approximately 300 other public companies. We acquired NetSilicon on February 13, 2002. The complaint named us as a defendant along with NetSilicon, certain of its officers and certain underwriters involved in NetSilicon's IPO, among numerous others, and asserted, among other things, that NetSilicon's IPO prospectus and registration statement violated federal securities laws because they contained material misrepresentations and/or omissions regarding the conduct of NetSilicon's IPO underwriters in allocating shares in NetSilicon's IPO to the underwriters' customers. We believed that the claims against the 16. CONTINGENCIES (CONTINUED) NetSilicon defendants were without merit and we defended the litigation vigorously. Pursuant to a stipulation between the parties, the two named officers were dismissed from the lawsuit, without prejudice, on October 9, 2002. As previously disclosed, the parties advised the District Court on February 25, 2009 that they had reached an agreement-in-principle to settle the litigation in its entirety. A stipulation of settlement was filed with the District Court on April 2, 2009. On June 9, 2009, the District Court preliminarily approved the proposed global settlement. Notice was provided to the class, and a settlement fairness hearing, at which members of the class had an opportunity to object to the proposed settlement, was held on September 10, 2009. On October 6, 2009, the District Court issued an order granting final approval to the settlement. Ten appeals were filed objecting to the definition of the settlement class and fairness of the settlement. Five of those appeals were dismissed with prejudice on October 6, 2010. On May 17, 2011, the Court of Appeals dismissed four of the remaining appeals. On January 10, 2012, the last remaining appeal was dismissed with prejudice, as a result of which the settlement became final, by its terms. In March 2012, our insurers paid to the plaintiffs on our behalf the full amount of the settlement share allocated to us of $337,838. We have no financial liability under the terms of the settlement agreement. As a result, during the second fiscal quarter of 2012, we reversed our accrued liability of $300,000 and the related receivable of $50,000. These amounts represented the estimated settlement of $300,000 less our $250,000 deductible. Patent Infringement Lawsuits On May 29, 2012, U.S. Ethernet Innovations, LLC filed a patent infringement lawsuit against us in federal court in the Eastern District of Texas. The lawsuit included allegations against us and one other company pertaining to the infringement of three patents related to integrated circuits, including architectures of network adapters and transmission of data in certain network interfaces. The lawsuit seeks monetary and non-monetary relief. We cannot predict the outcome of this matter or estimate a range of loss at this time or whether it will have a materially adverse impact on our business prospects and our consolidated financial condition, results of operations or cash flow. On May 11, 2010, SIPCO, LLC filed a complaint naming us as a defendant in federal court in the Eastern District of Texas. This claim subsequently was moved to the Northern District of Georgia. The complaint included allegations against us and five other companies pertaining to the infringement of SIPCO's patents by wireless mesh networking and multi-port networking products. On October 23, 2012, we settled the lawsuit for a payment of $500,000 which was recorded during the fourth quarter of fiscal 2012 and we entered into a royalty-bearing license agreement for future sales of licensed products sold during the term of the agreement through 2018. We do not expect this license agreement to have a material impact on our consolidated financial statements in the future. Collection Matter In December 2011, our wholly owned subsidiary, Spectrum Design Services, Inc., brought claims against Iota, Inc. (“Iota”) and Corsair Engineering, Inc. (“Corsair”) in Minnesota State District Court. The claims were made to collect unpaid receivables from Iota that are subject to a payment guaranty from Corsair. These claims arose out of a contract between Iota and Spectrum for the development of a custom product for Iota. Spectrum ceased work on the project for non-payment of invoices before making its claims. During our second quarter of fiscal 2012, Iota and Corsair removed the cases to Federal District Court in Minnesota and Iota asserted counterclaims against Spectrum for breach of contractual warranty, breach of contract and negligent misrepresentation. The counterclaims alleged damages for recovery of over $300,000 previously paid by Iota to Spectrum as well as lost profits and other damages. In connection with the mediation completed on June 29, 2012, we, Iota and Corsair signed an agreement to dismiss all claims related to this matter and reached a settlement on the unpaid receivable. The settlement did not have a material impact to us. In addition to the matters discussed above, in the normal course of business, we are subject to various claims and litigation, which may include, but are not limited to, patent infringement and intellectual property claims. Our management expects that these various claims and litigation will not have a material adverse effect on our consolidated financial statements. |

Summary of Significant Accounting Policies (Policies)
|
12 Months Ended | ||||
|---|---|---|---|---|---|
|
Sep. 30, 2012
|
|||||
| Accounting Policies [Abstract] | |||||
| Principles of Consolidation | Principles of Consolidation The consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. |
||||
| Cash Equivalents | Cash Equivalents Cash equivalents consist of money market accounts and other highly liquid investments purchased with an original maturity of three months or less. The carrying amounts approximate fair value due to the short maturities of these investments. |
||||
| Marketable Securities | Marketable Securities Marketable securities consist of certificates of deposit, commercial paper, corporate bonds and government municipal bonds. All marketable securities are accounted for as available-for-sale and are carried at fair value with unrealized gains and losses reported as a separate component of stockholders' equity. We obtain quoted market prices and trading activity for each security, where available, review the financial solvency of each security issuer and obtain other relevant information to estimate the fair value for each security in our investment portfolio. We regularly monitor and evaluate the value of our marketable securities. When assessing marketable securities for other-than-temporary declines in value, we consider several factors. These factors include: how significant the decline in value is as a percentage of the original cost, how long the market value of the investment has been less than its original cost, the underlying factors contributing to a decline in the prices of securities in a single asset class, the performance of the issuer's stock price in relation to the stock price of its competitors within the industry, expected market volatility, analyst recommendations, the views of external investment managers, any news or financial information that has been released specific to the investee and the outlook for the overall industry in which the issuer operates. If events and circumstances indicate that a decline in the value of a security has occurred and is other-than-temporary, we would record a charge to other income (expense). |
||||
| Accounts Receivable | Accounts Receivable Accounts receivable are stated at the amount we expect to collect, which is net of an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. The following factors are considered when determining the collectability of specific customer accounts: customer creditworthiness, past transaction history with the customer, and changes in customer payment terms or practices. In addition, overall historical collection experience, current economic industry trends, and a review of the current status of trade accounts receivable are considered when determining the required allowance for doubtful accounts. Based on our assessment, we provide for estimated uncollectible amounts through a charge to earnings and a credit to our allowance for doubtful accounts. Balances that remain outstanding after we have used reasonable collection efforts are written off through a charge to the allowance for doubtful accounts and a credit to accounts receivable. |
||||
| Inventories | Inventories Inventories are stated at the lower of cost or fair market value, with cost determined using the first-in, first-out method. Appropriate consideration is given to deterioration, obsolescence and other factors in evaluating fair market value. |
||||
| Property, Equipment and Improvements, Net | Property, Equipment and Improvements, Net Property, equipment and improvements are carried at cost, net of accumulated depreciation. Depreciation is provided by charges to operations using the straight-line method over the estimated asset useful lives. Furniture and fixtures and other 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) equipment are depreciated over a period of three to seven years. Building improvements and buildings are depreciated over ten and thirty-nine years, respectively. Equipment under capital lease is depreciated over the lesser of the lease term or its depreciable life. Expenditures for maintenance and repairs are charged to operations as incurred, while major renewals and betterments are capitalized. The assets and related accumulated depreciation accounts are adjusted for asset retirements and disposals with the resulting gain or loss included in operations. |
||||
| Identifiable Intangible Assets | Identifiable Intangible Assets Purchased proven technology, license agreements, covenants not to compete and other identifiable intangible assets are recorded at fair value when acquired in a business acquisition, or at cost when not purchased in a business acquisition. Purchased in-process research and development costs (IPR&D) related to business combinations are capitalized and amortized once it is placed in service. All other identifiable intangible assets are amortized on either a straight-line basis over their estimated useful lives of three to thirteen years or based on the pattern in which the asset is consumed. Useful lives for identifiable intangible assets are estimated at the time of acquisition based on the periods of time from which we expect to derive benefits from the identifiable intangible assets. Amortization of purchased and core technology is presented as a separate component of cost of sales in the Consolidated Statements of Operations. Amortization of all other acquired identifiable intangible assets is charged to operating expense as a component of general and administrative expense. Identifiable intangible assets are reviewed for impairment annually or whenever events or circumstances indicate that undiscounted expected future cash flows are not sufficient to recover the carrying value amount. We measure impairment loss by utilizing an undiscounted cash flow valuation technique using fair values indicated by the income approach. Impairment losses, if any, would be recorded in the period the impairment is identified. No impairments were identified during fiscal years 2012, 2011 or 2010. |
||||
| Goodwill | Goodwill Goodwill represents the excess of cost over the fair value of identifiable assets acquired. Goodwill is tested for impairment on an annual basis as of June 30, or more frequently if events or circumstances occur which could indicate impairment. As of June 30, 2012, our market capitalization was $264.3 million compared to our carrying value of $265.7 million. Our market capitalization plus our estimated control premium of 40% resulted in a fair value in excess of our carrying value by a margin of 39% and therefore no impairment was indicated. At September 30, 2012, our market capitalization was $263.3 million compared to our carrying value of $270.9 million. Since there were no triggering events through September 30, 2012, and our market capitalization plus our estimated control premium of 40% resulted in a fair value in excess of our carrying value by a margin of 36%, no impairment was indicated. The control premium used in our annual goodwill assessment at June 30, 2012 and our further evaluation of goodwill at September 30, 2012 was based on a recent control premium study as of June 30, 2012, resulting in a range of control premium of 30% to 45%. We concluded that a 40% control premium best represented the amount an investor would pay, over and above market capitalization, in order to obtain a controlling interest given the economic conditions at that time. In order to compute the above control premium, three methodologies were used, including (1) analyzing individual transactions within our industry, (2) analyzing industry-wide data, and (3) analyzing global transaction data. Individual transactions in the Communication Equipment or Computer & Peripherals industries were used to find transactions of target companies that operated in similar markets and shared similar operating characteristics with Digi. Transaction screening criteria included selection of transactions with the following characteristics: •At least 50 percent of a target company's equity sought by an acquirer, •Target company considered operating (not in bankruptcy), •Target company had publicly traded stock outstanding at the transaction date, and
In analyzing industry-wide data, transactions in three industries were identified that encompassed the products offered by us: Office Equipment and Computer Hardware, Communications, and Computer, Supplies and Services. Finally, control premiums were considered for both domestic and international transactions. 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) At June 30, 2011, our market capitalization exceeded the carrying value of our reporting unit by 28.6%; therefore, there was no indication of goodwill impairment. We have defined the criteria that will result in additional interim goodwill impairment testing. If these criteria are met, we will undertake an analysis to determine whether a goodwill impairment has occurred, which could have a material effect on our consolidated financial position and results of operations. The evaluation of asset impairment may require us to make assumptions about future cash flows and revenues. These assumptions require significant judgment and actual results may differ from assumed or estimated amounts. If these estimates and assumptions change, we may be required to recognize impairment losses in the future. There have been no goodwill impairment losses since the adoption of Accounting Standards Codification (ASC) 350 Intangibles-Goodwill and Others in fiscal 2003. |
||||
| Revenue Recognition | Revenue Recognition We recognize revenue in accordance with authoritative guidance issued by FASB related to revenue recognition. Revenue recognized for product sales was 95.5%, 95.5% and 96.7% of net sales in fiscal 2012, 2011 and 2010, respectively. We recognize product revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, collectability is reasonably assured and there are no post-delivery obligations, other than warranty. Under these criteria, product revenue generally is recognized upon shipment of product to customers, including Direct (end-user) / OEMs and distributors. Sales to authorized domestic distributors and Direct / OEMs are made with certain rights of return and price adjustment provisions. Estimated reserves for future returns and pricing adjustments are established by us based on an analysis of historical patterns of returns and price adjustments as well as an analysis of authorized returns compared to received returns, current on-hand inventory at distributors, and distribution sales for the current period. Estimated reserves for future returns and price adjustments are charged against revenues in the same period as the corresponding sales are recorded. Our non-product revenue represented 4.5%, 4.5% and 3.3% of net sales in fiscal 2012, 2011 and 2010, respectively. The majority of the non-product revenue was from professional and engineering services and represented 4.1%, 4.2% and 2.9% of net sales in fiscal 2012, 2011 and 2010, respectively. We also had revenue from cloud-based services, post-contract customer support, fees associated with technical support, training, royalties and the sale of software licenses. Our software development tools and development boards often include multiple elements, including hardware, software licenses, post-contract customer support, limited training and basic hardware design review. Our customers purchase these products and services during their product development process in which they use the tools to build network connectivity into the devices they are manufacturing. Revenue for professional and engineering services and training is recognized upon performance. Revenue from software licenses is recognized when earned. Revenues from contracts with multiple element arrangements are recognized as each element is earned based on the relative fair value of each element provided the delivered elements have value to customers on a standalone basis. Amounts allocated to each element are based on its vendor specific objective evidence, such as the sales price for the product or service when it is sold separately. Revenue from cloud-based services is earned in two ways: a) web-based management fees are considered to be earned on a monthly basis consistent with a monthly contractual commitment, and b) transaction fees that are billed to the customer at the larger of the minimum price or the number of transactions times the stated fee and are considered earned as the transactions occur. |
||||
| Research and Development | Research and Development Research and development costs are expensed when incurred. Research and development costs include compensation, allocation of corporate costs, depreciation, utilities, professional services and prototypes. Software development costs are expensed as incurred until the point that technological feasibility and proven marketability of the product are established. To date, the time period between the establishment of technological feasibility and completion of software development has been short, and no significant development costs have been incurred during that period. Accordingly, we have not capitalized any software development costs to date. |
||||
| Income Taxes | Income Taxes Deferred income taxes are recognized for the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts at each year end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Income tax expense is equal to the tax payable for the period and the change during the period in deferred tax assets and liabilities and also changes in income tax reserves. |
||||
| Net Income Per Common Share | Net Income Per Common Share Basic net income per common share is calculated based on the weighted average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the weighted average number of common and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares of our stock result from dilutive common stock options and shares purchased through our employee stock purchase plan. We use the treasury stock method to calculate the weighted-average shares used in the diluted earnings per share computation. Under the treasury stock method, the proceeds from exercise of an option, the amount of compensation cost, if any, for future service that we have not yet recognized, and the amount of estimated tax benefits that would be recorded in paid-in capital, if any, when the option is exercised are assumed to be used to repurchase shares in the current period. |
||||
| Stock-Based Compensation | Stock-Based Compensation Stock-based compensation expense represents the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. This cost must be recognized over the period during which an employee is required to provide the service (usually the vesting period). |
||||
| Foreign Currency Translation | Foreign Currency Translation Financial position and results of operations of our international subsidiaries are measured using local currencies as the functional currency, except for our Singapore location which uses the U.S. Dollar as its local currency. Assets and liabilities of these operations are translated at the exchange rates in effect at the end of each reporting period. Statements of operations accounts are translated at the weighted average rates of exchange prevailing during each reporting period. Translation adjustments arising from the use of differing currency exchange rates from period to period are included in accumulated other comprehensive income (loss) in stockholders' equity. Gains and losses on foreign currency exchange transactions, as well as translation gains or losses on transactions denominated in currencies other than an entity's functional currency are reflected in the statement of operations. During fiscal 2012, 2011 and 2010 there were net transaction gains (losses) of $(0.4) million, $(0.7) million and $0.3 million, respectively that were recorded in other income (expense). We have not implemented a formal hedging strategy, although we employ natural hedging of assets and liabilities denominated in foreign currencies to reduce our foreign currency risk. |
||||
| Use of Estimates and Risks and Uncertainties | Use of Estimates and Risks and Uncertainties The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates that could significantly affect our results of operations or financial condition involve the assignment of fair values upon acquisition of goodwill and other intangible assets and testing for impairment; the determination of our allowance for doubtful accounts and reserve for future returns and pricing adjustments; the estimation of our inventory obsolescence, warranty reserve, income tax reserves and other contingencies. |
||||
| Comprehensive Income (Loss) | Comprehensive Income (Loss) Our comprehensive income (loss) is comprised of net income, foreign currency translation adjustments and unrealized gains and losses on available-for-sale marketable securities, which are charged or credited to the accumulated other comprehensive income (loss) account in stockholders' equity. |
||||
| Recent Accounting Developments | Recent Accounting Developments In August 2012, the U.S. Securities and Exchange Commission (the “SEC”) adopted a rule mandated by the Dodd-Frank Act to require companies to publicly disclose their use of conflict minerals that originated in the Democratic Republic of the Congo or an adjoining country. The final rule applies to a company that uses minerals including tantalum, tin, gold or tungsten. The final rule requires companies to provide disclosure on a new form filed with the SEC, with the first specialized disclosure report due on May 31, 2014, for the 2013 calendar year, and annually on May 31 each year thereafter. We are currently evaluating the impact of adoption. In July 2012, the Financial Accounting Standards Board (“FASB”) issued ASU 2012-02, "Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment." The FASB amended its guidance on testing of indefinite-lived intangible assets for impairment. Under the amended guidance, companies may perform a qualitative assessment to determine whether further impairment testing is necessary, similar to the amended goodwill impairment testing guidance noted below. The guidance for indefinite-lived intangible assets is effective for annual and interim tests performed for fiscal years beginning after September 15, 2012, with an option for early adoption. We will adopt ASU 2012-02 effective for our fiscal year beginning October 1, 2012 and do not expect this pronouncement to have a material effect on our consolidated financial statements. In September 2011, the FASB issued Accounting Standards Update (“ASU”) No. 2011-08, “Intangibles-Goodwill and Other (Topic 350) Testing Goodwill for Impairment”. This guidance provides an update on how an entity tests goodwill for impairment. This revised guidance allows companies an option to make a qualitative evaluation about the likelihood of goodwill impairment. Under the revised guidance, a company is permitted to first assess qualitative factors to determine whether goodwill impairment exists prior to performing analysis comparing the fair value of a reporting unit to its carrying amount. If, based on the qualitative assessment, a company concludes it is more likely than not that the fair value of the reporting unit exceeds its carrying value, then quantitative testing for impairment is not necessary. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We, however, adopted this update early so it was effective for our fiscal year beginning October 1, 2011 (see Note 7 to the Condensed Consolidated Financial Statements). This guidance had no impact on our consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income”. This guidance eliminates the option to report other comprehensive income and its components in the consolidated statement of stockholders' equity. Rather it requires that all non-owner changes in stockholders' equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. This guidance also requires us to present on the face of the financial statements any reclassification adjustments for items that are reclassified from other comprehensive income to net income. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We will adopt this guidance beginning with our fiscal quarter ending December 31, 2012. The adoption of this guidance is not expected to have any effect on our consolidated financial position or results of operations, as it will only impact how certain information related to other comprehensive income is presented in our consolidated financial statements. In December 2011, FASB issued ASU No. 2011-12 which amends this guidance and defers only the presentation of reclassification of items out of accumulated comprehensive income. No other requirements of ASU No. 2011-05 are affected by this deferral. 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) In May 2011, the FASB issued ASU No. 2011-04, “Fair Value Measurements (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs”. This guidance updates many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements to ensure consistency between U.S. GAAP and International Financial Reporting Standards (“IFRS”). This guidance is to be applied prospectively and is effective during interim and annual periods beginning after December 15, 2011. We adopted this guidance beginning with our fiscal quarter ending March 31, 2012. This guidance had no impact on our consolidated financial statements. |

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item represents Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://www.xbrl.org/2003/role/presentationRef
