NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. BASIS OF PRESENTATION OF UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The interim unaudited condensed consolidated financial statements included in this Form 10-Q have been prepared by Digi International Inc. (the “Company,” “Digi,” “we,” “our,” or “us”) pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures, normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), have been condensed or omitted, pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto, including (but not limited to) the summary of significant accounting policies, presented in our Annual Report on Form 10-K for the year ended September 30, 2011 as filed with the SEC (“2011 Financial Statements”).

The condensed consolidated financial statements presented herein reflect, in the opinion of management, all adjustments which consist only of normal, recurring adjustments necessary for a fair statement of the condensed consolidated balance sheets and the condensed consolidated results of operations and cash flows for the periods presented. The condensed consolidated results of operations for any interim period are not necessarily indicative of results for the full year. The year-end condensed consolidated balance sheet data were derived from our 2011 Financial Statements, but do not include all disclosures required by U.S. GAAP.

Recently Issued Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board (“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. For us, this guidance would be effective for our fiscal year beginning October 1, 2012. 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.

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.

2. EARNINGS PER 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):

	Three months ended June 30,				Nine months ended June 30,
	2012		2011		2012		2011
Numerator:
Net income	$	2,307	$	3,615	$	5,153	$	8,170
Denominator:
Denominator for basic net income per common share — weighted average shares outstanding	25,770		25,369		25,705		25,236
Effect of dilutive securities:
Employee stock options and employee stock purchase plan	273		510		433		451
Denominator for diluted net income per common share — adjusted weighted average shares	26,043		25,879		26,138		25,687
Net income per common share, basic	$	0.09	$	0.14	$	0.20	$	0.32
Net income per common share, diluted	$	0.09	$	0.14	$	0.20	$	0.32

Because their effect would be anti-dilutive, certain potentially dilutive shares related to stock options to purchase common shares were not included in the above computation of diluted earnings per common share. This is because the options’ exercise prices were greater than the average market price of our common shares. For the three and nine month periods ended June 30, 2012, there were 3,254,285 and 2,019,690 potentially dilutive shares related to such stock options, respectively. For the three and nine month periods ended June 30, 2011, there were 1,921,684 and 1,767,934 potentially dilutive shares related to such stock options, respectively.

3. COMPREHENSIVE (LOSS) INCOME

Comprehensive (loss) income is comprised of net income, foreign currency translation adjustments and unrealized gain (loss) on available-for-sale marketable securities, net of tax. Comprehensive (loss) income was (in thousands):

	Three months ended June 30,						Nine months ended June 30,
	2012			2011			2012			2011
Net income	$	2,307		$	3,615		$	5,153		$	8,170

Accounts receivable, net:
Accounts receivable	$	24,984	$	26,772

	$	26,302	$	23,986

Inventories are stated at the lower of cost or market value, with cost determined using the first-in, first-out method.

5. 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 June 30, 2012, 56 of our 72 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. At June 30, 2012 our marketable securities were (in thousands):

	Amortized Cost (1)		Unrealized Gains		Unrealized Losses (2)			Fair Value (1)

(1) Included in amortized cost and fair value is purchased and accrued interest of $478.

(2) The aggregate related fair value of securities with unrealized losses as of September 30, 2011 was $43,755.

6. 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:

• Level 1 — Inputs are quoted prices in active markets for identical assets or liabilities.

• Level 2 — Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.

• Level 3 — Inputs are unobservable for the asset or liability and their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. Level 3 may also include certain investment securities for which there is limited market activity or a decrease in the observability of market pricing for the investments, such that the determination of fair value requires significant judgment or estimation.

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.

6. FAIR VALUE MEASUREMENTS (CONTINUED)

The following tables provide information by level for financial assets that are measured at fair value on a recurring basis (in thousands):

			Fair Value Measurements at June 30, 2012 using:
	Total carrying value at June 30, 2012		Quoted price in active markets (Level 1)		Significant other observable inputs (Level 2)		Significant unobservable inputs (Level 3)
Cash equivalents:
Money market	$	12,435	$	12,435	$	—	$	—
Available-for-sale marketable securities:
Corporate bonds	45,438		—		45,438		—
Commercial paper	4,998		—		4,998		—
Certificates of deposit	8,506		—		8,506		—
Government municipal bonds	12,502		—		12,502		—
Total cash equivalents and marketable securities measured at fair value	$	83,879	$	12,435	$	71,444	$	—

			Fair Value Measurements at September 30, 2011 using:
	Total carrying value at September 30, 2011		Quoted price in active markets (Level 1)		Significant other observable inputs (Level 2)		Significant unobservable inputs (Level 3)
Cash equivalents:
Money market	$	30,474	$	30,474	$	—	$	—
Available-for-sale marketable securities:
Corporate bonds	24,171		—		24,171		—
Commercial paper	4,995		—		4,995		—
Certificates of deposit	8,766		—		8,766		—
Government municipal bonds	15,195		—		15,195		—
Total cash equivalents and marketable securities measured at fair value	$	83,601	$	30,474	$	53,127	$	—

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 nine months ended June 30, 2012.

We had no financial assets valued with Level 3 inputs as of June 30, 2012 nor did we purchase or sell any Level 3 financial assets during the nine months ended June 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.

Amortization expense was $1.1 million and $1.5 million for the three month periods ended June 30, 2012 and 2011, respectively. Amortization expense was $3.5 million and $4.9 million for the nine months ended June 30, 2012 and 2011, respectively. Amortization expense is recorded on our consolidated statement of operations within cost of sales, primarily within amortization of purchased and core technology, and in general and administrative expense. Estimated amortization expense related to identifiable intangible assets for the remainder of fiscal 2012 and the five succeeding fiscal years is (in thousands):

2012 (three months)	$	939
2013	3,641
2014	2,777
2015	2,108

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. At June 30, 2012, we had approximately $85.5 million of goodwill on our balance sheet, which is held in a single reporting unit, resulting from eight different acquisitions that have taken place over the past twelve years. Historically we have approached our annual goodwill impairment assessment by estimating fair value using our market capitalization, compared to our carrying value. In certain years, a control premium has been included in this analysis. As a result of the lower than anticipated results for our second quarter of fiscal 2012, the lowering of our annual forecast for fiscal 2012 and the subsequent decline in our stock, we performed a control premium study to determine the appropriate control premium to include in the calculation of fair value. We engaged a third party valuation firm to assist us in performing the control premium analysis. In order to estimate the range of control premiums appropriate for us, three methodologies were used, including (1) analysis of individual transactions within our industry; (2) analysis of industry-wide data, and (3) analysis of global transaction data. The control premium analysis resulted in a range of control premium of 30% to 45%. We have further analyzed the data provided and estimated that a 40% control premium best represents the amount an investor would likely pay, over and above market capitalization, in order to obtain a controlling interest given the economic conditions at this time. This control premium approximates the midpoint of the range and is slightly higher than our previous control premium of 35%, reflecting the overall increase in control premiums over the past several years.

7. GOODWILL AND OTHER IDENTIFIABLE INTANGIBLE ASSETS (CONTINUED)

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.

We have defined the criteria that could result in additional interim goodwill impairment testing. If these criteria are met, we will undertake the analysis to determine whether a goodwill impairment has occurred. An impairment could have a material effect on our consolidated balance sheet and results of operations. The calculation of asset impairment requires 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.

8. INCOME TAXES

Income taxes have been provided at an overall effective rate of 20.6% and 31.8% for the nine month periods ended June 30, 2012 and 2011, respectively. Our effective tax rate will vary based on a variety of factors, including overall profitability, the geographical mix of income before taxes and related statutory tax rate in each jurisdiction, and discrete events, such as settlements of audits.

In the first nine months of fiscal 2012, we recorded a discrete tax benefit of $1.2 million, which included a benefit of $1.1 million recorded in the third fiscal quarter of 2012 for additional research and development tax credits identified for fiscal years ended September 30, 2009, 2010 and 2011. These additional tax credits resulted from a recently completed research and development tax credit study. During the first quarter of fiscal 2012, we recorded a discrete tax benefit of $0.1 million resulting from the release of income tax reserves due to the expiration of the statutes of limitations from various U.S. tax jurisdictions. These discrete tax benefits reduced our effective tax rate by 18.6 percentage points for the nine month period ended June 30, 2012. Our income tax rate before consideration of discrete tax benefits is higher for the nine months ended June 30, 2012 as compared to the nine months ended June 30, 2011 primarily due to expiration of the research and development tax credit on December 31, 2011 for the current fiscal year and a reduction in domestic tax benefits.

In the first quarter of fiscal 2011, we recorded a discrete tax benefit of $0.6 million. This benefit primarily resulted from the reversal of tax reserves from various jurisdictions 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 4.8 percentage points for the nine month period ended June 30, 2011 to 31.8%.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is (in thousands):

Unrecognized tax benefits as of September 30, 2011	$	2,061
Increases related to:
Prior year income tax positions	631
Decreases related to:
Prior year income tax positions	(67		)
Expiration of statute of limitations	(83		)
Unrecognized tax benefits as of June 30, 2012	$	2,542

The total amount of unrecognized tax benefits that, if recognized, would affect our effective tax rate is $2.5 million. There are no tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will increase or decrease significantly over the next 12 months.

We recognize interest and penalties related to income tax matters in income tax expense. During both the three and nine month periods ended June 30, 2012 and 2011, 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 June 30, 2012 and September 30, 2011, of $0.6 million. Our long-term income taxes payable on our condensed consolidated balance

8. INCOME TAXES (CONTINUED)

sheets includes these accrued interest and penalties in addition to the unrecognized tax benefits in the table above.

At June 30, 2012, we had approximately $17.3 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. Since 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, it is not practicable to determine the unrecognized deferred tax liability; however, based on current tax laws and structures, we do not believe this would have a material impact on our current consolidated financial position, results of operations and cash flows.

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 2007 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 2007.

9. PRODUCT WARRANTY OBLIGATION

In general, we warrant our products to be free from defects in material and workmanship under normal use and service. The warranty periods generally range from one to five years. We typically have the option to either repair or replace products we deem defective with regard to material or workmanship. Estimated warranty costs are accrued in the period that the related revenue is recognized based upon an estimated average per unit repair or replacement cost applied to the estimated number of units under warranty. These estimates are based upon historical warranty incidents and are evaluated on an ongoing basis to ensure the adequacy of the warranty accrual.

The following table summarizes the activity associated with the product warranty accrual (in thousands) and is included on our Condensed Consolidated Balance Sheets in Other Current Liabilities:

	Three months ended June 30,

We are not responsible for, and do not warrant that, custom software versions, created by original equipment manufacturer (OEM) customers based upon our software source code, will function in a particular way, will conform to any specifications or are fit for any particular purpose. Further, we do not indemnify these customers from any third-party liability as it relates to or arises from any customization or modifications made by the OEM customer.

10. CONTINGENCIES

Contingent obligations

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. The complaint seeks monetary and non-monetary relief.  We cannot predict the outcome of this matter or estimate a range of possible 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.

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 results of operations or financial condition.

11. RESTRUCTURING

U.S. 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.

Breisach 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 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. The lease on the Breisach facility ends in July 2013. As a result of these initiatives, we recorded a total charge of $0.5 million on a pre-tax basis, which consisted of $0.4 million for employee termination costs for 25 employees and $0.1 million for asset write-downs. The restructuring charge was recorded as follows: $0.2 million in the fourth quarter of fiscal 2011, $0.2 million in the first quarter of fiscal 2012, and $0.1 million in the second quarter of fiscal 2012. The final payments were completed in April 2012.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Our management’s discussion and analysis should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended September 30, 2011, as well as our reports on Forms 10-Q and 8-K and other publicly available information.

SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

This Form 10-Q contains certain statements that are “forward-looking statements” as that term is defined under the Private Securities Litigation Reform Act of 1995, and within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.

The words “assume,” “believe,” “anticipate,” “intend,” “estimate,” “target,” “may,” “will,” “expect,” “plan,” “project,” “should,” or “continue” or the negative thereof or other expressions, which are predictions of or indicate future events and trends and which do not relate to historical matters, identify forward-looking statements. Among other items, these statements relate to expectations of the business environment in which we operate, projections of future performance, perceived marketplace opportunities and statements regarding our mission and vision. Such statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions, including risks related to the highly competitive market in which our company operates, rapid changes in technologies that may displace products sold by us, declining prices of networking products, our reliance on distributors and other third parties to sell our products, delays in product development efforts, uncertainty in user acceptance of our products, the ongoing shift of our sales efforts to focus more on the delivery of broader based solutions which can be a more complex sales process, has not been a historical sales focus of our company and can involve longer sales cycles than the sale of our legacy hardware products, potential liabilities that can arise if any of our products have design or manufacturing defects, our ability to defend or settle satisfactorily any litigation, uncertainty in global economic conditions and economic conditions within particular regions of the world which could negatively affect product demand and the financial solvency of customers and suppliers, the impact of natural disasters and other events beyond our control that negatively impacted our supply chain and customers including the flooding in Thailand in 2011 that impacted the operations of one of our contract manufacturers and impacted our operations and financial results, the ability to achieve the anticipated benefits and synergies associated with acquisitions, and changes in our level of revenue or profitability which can fluctuate for many reasons beyond our control. These and other risks, uncertainties and assumptions identified from time to time in our filings with the United States Securities and Exchange Commission, including without limitation, our annual report on Form 10-K for the year ended September 30, 2011 and subsequent quarterly reports on Form 10-Q and other filings, could cause the company’s future results to differ materially from those expressed in any forward-looking statements made by us or on our behalf. Many of such factors are beyond our ability to control or predict. These forward-looking statements speak only as of the date for which they are made. We disclaim any intent or obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.

CRITICAL ACCOUNTING POLICIES

A description of our critical accounting policies was provided in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of our Annual Report on Form 10-K for the year ended September 30, 2011. An update to our critical accounting policy related to goodwill is included below.

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. Under the new accounting guidance adopted for fiscal 2012 (ASU 2011-08, "Intangibles-Goodwill and Other (Topic 350) Testing Goodwill for Impairment"), we have the option of evaluating qualitative factors (including economic conditions, industry and market considerations and overall financial performance) to determine whether it is necessary to perform the first step of the two-step goodwill process. This initial evaluation is referred to as the "Step 0 analysis". If it is determined that it is more likely than not (a likelihood of more than 50% impairment) that the fair value of a reporting unit is less than its carrying amount, then we would need to proceed to the first step ("Step One") of the two-step goodwill test. Since we have one reporting unit, we may elect to proceed directly to the Step One evaluation in which we compare the fair value of our reporting unit as evidenced by market capitalization to our carrying value. Fair value may include a control premium. If after performing Step One of the evaluation we determine that it is more likely than not that the fair value of our reporting unit is less than its carrying amount, then we would proceed to the second step (“Step Two”) of the impairment test. At June 30, 2012 our market capitalization was less than the carrying value of our reporting unit by less than 1%. Including a control premium of 40%, fair value exceeded the carrying value by 39%. As a result, there was no indication of goodwill impairment (See Note 7 to our Condensed Consolidated Financial Statements).

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

OVERVIEW

We are a leading provider of machine to machine (M2M) networking products and solutions that enable the connection, monitoring and control of local or remote physical assets by electronic means. These networking products and solutions connect communication hardware to a physical asset so that information about the asset's status and performance can be sent to a computer system and used to improve or automate one or more processes. Increasingly these products and solutions are deployed via wireless networks. Our products are deployed by a wide range of businesses and institutions. We compete for customers on the basis of existing and planned product features, service and software application capabilities, company reputation, brand recognition, technical support, relationships with partners, quality and reliability, product development capabilities, price and availability.

During our third quarter of fiscal 2012, revenue from certain customers from whom we expected significant purchases was lower than anticipated, particularly in our North American region. In addition, we recorded revenue during the third quarter of fiscal 2011 resulting from large orders from a few customers that were not recurring as their projects were completed. We also experienced an ongoing decline of our mature products, primarily included in our wired product category.

We recorded a pre-tax $1.0 million ($0.6 million net of taxes) restructuring charge in the third quarter of fiscal 2012, which reduced diluted earnings per share by $0.02. The restructuring relates primarily to changes being implemented to focus on a shift in our business more aggressively to 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. 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.

We recorded a discrete tax benefit of $1.1 million, or $0.04 per diluted share, during the third fiscal quarter of 2012 for additional research and development tax credits identified for fiscal years ended September 30, 2009, September 30, 2010 and September 30, 2011 resulting from a recently completed research and development tax credit study.

We have been transitioning over the past several years from sales of wired products to sales of wireless products and solutions.  During this transition, to date we have focused primarily on sales into four vertical markets:  energy, fleet, medical and tank monitoring.  In the second fiscal quarter of 2012 we announced new strategic relationships with Freestyle, Wind River and Intel that we believe will extend the benefits of cloud connectivity through our iDigi® Device Cloud to allow developers and OEMs to build connected products and cloud enabled services more rapidly. We believe that these relationships signal the beginning of a broader based horizontal market strategy which will eventually modify our original vertical market strategy which emphasized sales of hardware products to sales of broader M2M solutions which include hardware, professional services and cloud-based software services.

We anticipate that future growth will result from products and services that are developed internally as well as from products and services that are acquired. Our suite of products and solutions primarily includes hardware and related software solutions, wireless product design, consultative services, managed services and development services, custom application design services and the iDigi® M2M cloud-based service.

NET SALES

Net sales decreased by $6.7 million, or 12.2%, for the three months ended June 30, 2012 compared to the three months ended June 30, 2011. Net sales decreased by $9.0 million, or 5.9%, for the nine months ended June 30, 2012 compared to the nine months ended June 30, 2011. Pricing was not a significant factor in changes in net sales during the three and nine month periods ended June 30, 2012.

Net Sales by Non-Embedded and Embedded Product Categories

The following summarizes our net sales by non-embedded and embedded product categories:

	Three months ended June 30,								% incr.		Nine months ended June 30,								% incr.
($ in thousands)	2012				2011				(decr.)		2012				2011				(decr.)

Non-embedded products

Our non-embedded net sales decreased by $5.8 million, or 20.5%, for the three months ended June 30, 2012 compared to the three months ended June 30, 2011. The decrease was primarily driven by decreases in net sales of $3.3 million for serial servers, $1.6 million for cellular products, $0.7 million for wireless communication adaptors and $0.7 million for USB connected products, partially offset by an increase of $0.5 million in net sales of serial cards. For the nine months ended June 30, 2012 compared to the nine months ended June 30, 2011, our non-embedded net sales decreased by $11.8 million, or 14.2%. The decrease primarily was driven by decreases in net sales of $4.7 million for serial servers, $2.9 million for wireless communication adaptors, $2.9 million for cellular products and $1.3 million for serial cards and USB connected devices. Non-embedded products that are mature include serial cards, serial servers and USB connected products. We expect the net sales of these mature products to continue to decline.

Our embedded net sales decreased by $0.9 million, or 3.2%, for the three months ended June 30, 2012 compared to the three months ended June 30, 2011. The decrease mostly was due to a decrease in net sales of chips and embedded modules.

18

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

Embedded net sales increased by $2.8 million, or 4.0%, for the nine months ended June 30, 2012 compared to the nine months ended June 30, 2011. Most of the increase is due to increased net sales of embedded modules. We believe that our Rabbit modules and chips and software are maturing and will continue to experience declines in net sales. In certain instances, Rabbit products may be replaced by other Digi products.

Our wireless products comprised 43.5% of our net sales for the third quarter of fiscal 2012 and 41.6% of our net sales for the third quarter of fiscal 2011. We expect that our sales of wired products will continue to decline. We anticipate that our sales of wireless products will grow at a faster rate than the decline of our sales of wired products. As we continue to transition to a wireless products and solutions-based sales organization, we may experience uneven demand, that may cause fluctuations in wireless revenue in future quarters.

Net sales in North America decreased by $4.7 million and $5.3 million for the three and nine months ended June 30, 2012 compared to the same periods ended June 30, 2011, respectively. The decrease was due primarily to large revenue opportunities with new customers that have been slower to develop than expected and lower than expected sales in our Rabbit product line. Net sales in Europe, Middle East & Africa (“EMEA”) decreased by $1.1 million and $2.0 million for the three and nine months ended June 30, 2012 compared to the same periods ended June 30, 2011, respectively. The decrease was primarily due to general economic weakness in Europe as well as lower than expected sales from cellular products. Asia countries net sales decreased by $0.5 million and $1.5 million for the three and nine months ended June 30, 2012 compared to the same periods ended June 30, 2011, respectively, primarily due to delay of significant projects from customers. Net sales in Latin America decreased by $0.6 million and $0.1 million for the three and nine months ended June 30, 2012 compared to the same periods ended June 30, 2011, respectively, primarily due to the delay of projects from certain customers.

The fluctuation of foreign currency rates had an unfavorable impact on net sales of $0.5 million and $0.8 million for the three and nine month periods ended June 30, 2012, respectively, when compared to the same periods a year ago, primarily related to the weakening of the Euro compared to the U.S. dollar.

GROSS MARGIN

Gross margins were 53.1% and 52.7% for the three and nine months ended June 30, 2012, respectively. This compares to gross margins of 53.0% and 51.9% for the three and nine months ended June 30, 2011, respectively. The increase in the gross margin for both the three and nine months ended June 30, 2012 as compared to the same periods a year ago primarily was due to a reduction of purchased and core technology amortization of 0.3 percentage points and 0.5 percentage points, respectively. This is because certain intangible assets related to these technologies are now fully amortized. Manufacturing expenses for the three months ended June 30, 2012 compared to the three months ended June 30, 2011, were approximately the same, which increased as a percentage of net sales due to lower revenue in the third quarter of fiscal 2012. This was partially offset by product cost

19

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

savings and favorable product mix. Manufacturing expenses for the nine months ended June 30, 2012 compared to the nine months ended June 30, 2011, decreased by 0.3 percentage points primarily due to manufacturing initiatives to reduce expenses.

OPERATING EXPENSES

The following summarizes our total operating expenses, in dollars and as a percentage of net sales:

	Three months ended June 30,								$ incr.			Nine months ended June 30,									$ incr.
($ in thousands)	2012				2011				(decr.)			2012				2011					(decr.)

Sales and marketing expenses for the three months ended June 30, 2012 as compared to the three months ended June 30, 2011, decreased by $0.2 million primarily related to a decrease in commissions. For the nine months ended June 30, 2012 as compared to the nine months ended June 30, 2011, sales and marketing expenses increased by $0.9 million respectively. This increase primarily related to increased headcount and associated compensation expenses, partially offset by a reduction in incentive compensation.

Research and development expenses decreased $0.1 million for the three months ended June 30, 2012 as compared to the three months ended June 30, 2011 due to lower compensation expense as incentive compensation accruals were at a reduced level compared to the same period in the prior fiscal year and lower headcount. This was partially offset by an increase of $0.2 million in product certification and custom development costs. Research and development expenses increased $0.2 million for the nine months ended June 30, 2012 as compared to the nine months ended June 30, 2011.

General and administrative expenses were essentially unchanged for the three months ended June 30, 2012 compared to the three months ended June 30, 2011. There was an increase in professional fees, which was offset by a decrease in compensation-related expenses and amortization expense as certain intangible assets are becoming fully amortized. For the nine months ended June 30, 2012 compared to the nine months ended June 30, 2011, the net increase in general and administrative expenses of $0.1 million was due to increases in bad debt expense of $0.5 million, compensation-related expense of $0.2 million and professional fees and outside services of $0.2 million. This partially was offset by a decrease of $0.5 million related to amortization expense as certain intangible assets are now fully amortized and a decrease of $0.3 million from the reversal of a reserve for the NetSilicon IPO litigation as our insurers paid to the plaintiffs the full amount of the settlement share allocated to us.

Restructuring expense was $1.0 million during the three months ended June 30, 2012 related to the U.S. restructuring announced April 26, 2012 (see Note 11 to the Condensed Consolidated Financial Statements). For the nine months ended June 30, 2012 compared to the nine months ended June 30, 2011, restructuring expense increase $1.3 million due to $1.0 million of U.S. restructuring mentioned above and $0.3 million in the first six months of fiscal 2012 for the Breisach, Germany restructuring announced July 21, 2011.

OTHER INCOME (EXPENSE), NET

Other income (expense), net increased by $0.2 million for the three months ended June 30, 2012 compared to the three months ended June 30, 2011, primarily due to a decrease in foreign currency net loss. Other income (expense), net increased by $0.7 million for the nine months ended June 30, 2012 compared to the nine months ended June 30, 2011, due to a reduction in foreign currency net loss of $0.5 million, a gain on the sale of an investment for $0.1 million in the first quarter of fiscal 2012 and a $0.1 million increase in interest income net of interest expense.

20

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

INCOME TAXES

In the first nine months of fiscal 2012, we recorded a discrete tax benefit of $1.2 million, which included a benefit of $1.1 million recorded in the third fiscal quarter of 2012 for additional research and development tax credits identified for fiscal years ended September 30, 2009, 2010 and 2011. These additional tax credits resulted from a recently completed research and development tax credit study. During the first quarter of fiscal 2012, we recorded a discrete tax benefit of $0.1 million resulting from the release of income tax reserves due to the expiration of the statutes of limitations from various U.S. tax jurisdictions. These discrete tax benefits reduced our effective tax rate by 18.6 percentage points for the nine month period ended June 30, 2012. Our income tax rate before consideration of discrete tax benefits is higher for the nine months ended June 30, 2012 as compared to the nine months ended June 30, 2011 primarily due to expiration of the research and development tax credit on December 31, 2011 for the current fiscal year and a reduction in domestic tax benefits.

In the first quarter of fiscal 2011, we recorded a discrete tax benefit of $0.6 million. This benefit primarily resulted from the reversal of tax reserves from various jurisdictions 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 4.8 percentage points for the nine month period ended June 30, 2011 to 31.8%.

LIQUIDITY AND CAPITAL RESOURCES

We have financed our operations and capital expenditures principally with funds generated from operations. At June 30, 2012, we had cash, cash equivalents and short-term marketable securities of $108.5 million compared to $106.2 million at September 30, 2011. Our working capital (total current assets less total current liabilities) was $146.7 million at June 30, 2012 and $142.7 million at September 30, 2011. We presently anticipate total fiscal 2012 capital expenditures will be approximately $4.3 million.

Reconciliation of Changes in Operating Assets and Liabilities:

	Nine months ended June 30,						$ incr.
($ in thousands)	2012			2011			(decr.)
Accounts receivable	$	89		$	(3,670	)	$	3,759

Changes in operating assets and liabilities	$	(5,867	)	$	(1,854	)	$	(4,013	)

Net cash provided by operating activities was $9.0 million for the nine months ended June 30, 2012 as compared to $16.2 million for the nine months ended June 30, 2011, a net decrease of $7.2 million. This decrease primarily was due to a decrease in net earnings of $3.0 million, a reduction of non-cash expenses for depreciation and amortization of $1.1 million, a decrease in operating assets and liabilities of $4.0 million and a decrease in the change of deferred income tax benefit of $0.9 million. It was partially offset by net increases in non-cash expenses for restructuring charges of $1.3 million, and $0.5 million in bad debt provision. The decrease in operating assets and liabilities of $4.0 million is due primarily to an outflow of $3.8 million due to increased inventory balances, a decrease of $3.3 million in accrued expenses mostly related to accrued compensation and a $0.6 million decrease in accounts payable. This partially was offset by an increase of $3.8 million in accounts receivable for the nine months ended June 30, 2011.

Net cash used in investing activities was $21.1 million during the nine months ended June 30, 2012 as compared to net cash used in investing activities of $10.8 million during the nine months ended June 30, 2011. During the first nine months of fiscal 2012 as compared the the first nine months of fiscal 2011, we used an additional $9.6 million for net purchases of marketable securities and an additional $0.8 million for net capital expenditures.

Cash provided by financing activities was $1.5 million and $3.1 million during the nine months ended June 30, 2012 and 2011, respectively, a net decrease of $1.6 million. This primarily was related to less proceeds from employee stock option plan

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

transactions during the first nine months of fiscal 2012 as compared to the same period a year ago.

We believe that our current cash, cash equivalents and marketable securities balances, cash generated from operations and our ability to secure debt and/or equity financing will be sufficient to fund our business operations for at least the next twelve months. We believe that our cash equivalents and short-term marketable securities are liquid and accessible. The objectives of our investment policy are the preservation of principal and maintenance of liquidity. We intend to maintain a highly liquid portfolio by investing only in those marketable securities that we believe have active secondary or resale markets.

At June 20, 2012, our total cash and cash equivalents and marketable securities balance was $108.5 million. This balance includes approximately $26.9 million of cash and cash equivalents held by our controlled foreign subsidiaries, of which approximately $17.3 million represents accumulated undistributed foreign earnings. 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 provided. 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. Since 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, it is not practicable to determine the unrecognized deferred tax liability; however, based on current tax laws and structures, we do not believe this would have a material impact on our current consolidated financial position and cash flows.

On July 25, 2012 our Board of Directors authorized a new program to repurchase up to $20 million of our common stock. The new repurchase authorization expires on September 30, 2013. In connection with this new repurchase authorization, the Board terminated the prior repurchase authorization, under which 135,638 shares remained available for repurchase. Shares repurchased under the new program may be made through open market and privately negotiated transactions from time to time and in amounts that management deems appropriate. The timing of share repurchases will depend upon market conditions and other corporate considerations.

As of June 30, 2012, there were no material changes to our contractual obligations as disclosed in our Annual Report on Form 10-K for the year ended September 30, 2011.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In September 2011, the Financial Accounting Standards Board (“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. For us, this guidance would be effective for our fiscal year beginning October 1, 2012. 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.

22

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (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.

23

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE RISK

Our exposure to interest rate risk relates primarily to our investment portfolio. Our marketable securities are classified as available-for-sale and are carried at fair value. Marketable securities consist of certificates of deposit, commercial paper, corporate bonds and government municipal bonds. Our investment policy specifies the types of eligible investments and minimum credit quality of our investments, as well as diversification and concentration limits which mitigate our risk. We do not use derivative financial instruments to hedge against interest rate risk because the majority of our investments mature in less than a year.

FOREIGN CURRENCY RISK

We have transactions that are executed in the U.S. Dollar, British Pound, Euro, Japanese Yen and Indian Rupee. As a result, we are exposed to foreign currency transaction risk associated with certain sales transactions being denominated in Euros, British Pounds, Japanese Yen or Indian Rupees, and foreign currency translation risk as the financial position and operating results of our foreign subsidiaries are translated into U.S. Dollars for consolidation. We have not implemented a formal hedging strategy to reduce foreign currency risk.

For the nine months ended June 30, 2012 and 2011, we had approximately $58.9 million and $62.6 million, respectively, of net sales to foreign customers including export sales. Of these sales, $17.9 million and $21.4 million, respectively, were denominated in foreign currency, predominantly Euros and British Pounds. In future periods, we expect a significant portion of sales will continue to be made in both Euros and British Pounds.

The table below compares the average monthly exchange rates of the Euro, British Pound, Japanese Yen and Indian Rupee to the U.S. Dollar:

	Nine months ended June 30,		% increase
	2012	2011	(decrease)
Euro	1.3149	1.3884	(5.3	)%
British Pound	1.5754	1.6047	(1.8	)%
Japanese Yen	0.0127	0.0122	4.1	%
Indian Rupee	0.0192	0.0221	(13.1	)%

A 10% change from the first nine months of fiscal year 2012 average exchange rate for the Euro, British Pound, Japanese Yen and Indian Rupee to the U.S. Dollar would have resulted in a 1.2% increase or decrease in net sales and a 1.8% increase or decrease in stockholders’ equity due to foreign currency translation. The above analysis does not take into consideration any pricing adjustments we might consider in response to changes in such exchange rates.

CREDIT RISK

We have some exposure to credit risk related to our accounts receivable portfolio. Exposure to credit risk is controlled through regular monitoring of customer financial status, credit limits and collaboration with sales management on customer contacts to facilitate payment.

Investments are made in accordance with our investment policy and consist of certificates of deposit, commercial paper, money market funds, government municipal bonds and corporate bonds. We may have some credit exposure related to the fair value of our securities, which could change based on changes in market conditions. If market conditions deteriorate or if these securities experience credit rating downgrades, we may incur impairment charges for securities in our investment portfolio. All of our securities are held domestically.

24

ITEM 4. CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

As of the end of the period covered by this report, we conducted an evaluation, under the supervision and with the participation of the principal executive officer and principal financial officer, of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)). Based on this evaluation, the principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act was recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and is accumulated and communicated to our management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

There was no change in our internal control over financial reporting during our most recently completed fiscal quarter that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Accounting Policies [Abstract]

BASIS OF PRESENTATION OF UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND SIGNIFICANTACCOUNTING POLICIES

BASIS OF PRESENTATION OF UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The interim unaudited condensed consolidated financial statements included in this Form 10-Q have been prepared by Digi International Inc. (the “Company,” “Digi,” “we,” “our,” or “us”) pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures, normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), have been condensed or omitted, pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto, including (but not limited to) the summary of significant accounting policies, presented in our Annual Report on Form 10-K for the year ended September 30, 2011 as filed with the SEC (“2011 Financial Statements”).

The condensed consolidated financial statements presented herein reflect, in the opinion of management, all adjustments which consist only of normal, recurring adjustments necessary for a fair statement of the condensed consolidated balance sheets and the condensed consolidated results of operations and cash flows for the periods presented. The condensed consolidated results of operations for any interim period are not necessarily indicative of results for the full year. The year-end condensed consolidated balance sheet data were derived from our 2011 Financial Statements, but do not include all disclosures required by U.S. GAAP.

Recently Issued Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board (“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. For us, this guidance would be effective for our fiscal year beginning October 1, 2012. 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.

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.

Earnings Per Share [Abstract]

EARNINGS PER SHARE

EARNINGS PER 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):

	Three months ended June 30,				Nine months ended June 30,
	2012		2011		2012		2011
Numerator:
Net income	$	2,307	$	3,615	$	5,153	$	8,170
Denominator:
Denominator for basic net income per common share — weighted average shares outstanding	25,770		25,369		25,705		25,236
Effect of dilutive securities:
Employee stock options and employee stock purchase plan	273		510		433		451
Denominator for diluted net income per common share — adjusted weighted average shares	26,043		25,879		26,138		25,687
Net income per common share, basic	$	0.09	$	0.14	$	0.20	$	0.32
Net income per common share, diluted	$	0.09	$	0.14	$	0.20	$	0.32

Because their effect would be anti-dilutive, certain potentially dilutive shares related to stock options to purchase common shares were not included in the above computation of diluted earnings per common share. This is because the options’ exercise prices were greater than the average market price of our common shares. For the three and nine month periods ended June 30, 2012, there were 3,254,285 and 2,019,690 potentially dilutive shares related to such stock options, respectively. For the three and nine month periods ended June 30, 2011, there were 1,921,684 and 1,767,934 potentially dilutive shares related to such stock options, respectively.

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. At June 30, 2012, we had approximately $85.5 million of goodwill on our balance sheet, which is held in a single reporting unit, resulting from eight different acquisitions that have taken place over the past twelve years. Historically we have approached our annual goodwill impairment assessment by estimating fair value using our market capitalization, compared to our carrying value. In certain years, a control premium has been included in this analysis. As a result of the lower than anticipated results for our second quarter of fiscal 2012, the lowering of our annual forecast for fiscal 2012 and the subsequent decline in our stock, we performed a control premium study to determine the appropriate control premium to include in the calculation of fair value. We engaged a third party valuation firm to assist us in performing the control premium analysis. In order to estimate the range of control premiums appropriate for us, three methodologies were used, including (1) analysis of individual transactions within our industry; (2) analysis of industry-wide data, and (3) analysis of global transaction data. The control premium analysis resulted in a range of control premium of 30% to 45%. We have further analyzed the data provided and estimated that a 40% control premium best represents the amount an investor would likely pay, over and above market capitalization, in order to obtain a controlling interest given the economic conditions at this time. This control premium approximates the midpoint of the range and is slightly higher than our previous control premium of 35%, reflecting the overall increase in control premiums over the past several years.

7. GOODWILL AND OTHER IDENTIFIABLE INTANGIBLE ASSETS (CONTINUED)

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.

We have defined the criteria that could result in additional interim goodwill impairment testing. If these criteria are met, we will undertake the analysis to determine whether a goodwill impairment has occurred. An impairment could have a material effect on our consolidated balance sheet and results of operations. The calculation of asset impairment requires 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.

Fair Value Measurements

Fair Value Disclosures [Abstract]

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:

• Level 1 — Inputs are quoted prices in active markets for identical assets or liabilities.

• Level 2 — Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.

• Level 3 — Inputs are unobservable for the asset or liability and their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. Level 3 may also include certain investment securities for which there is limited market activity or a decrease in the observability of market pricing for the investments, such that the determination of fair value requires significant judgment or estimation.

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.

6. FAIR VALUE MEASUREMENTS (CONTINUED)

The following tables provide information by level for financial assets that are measured at fair value on a recurring basis (in thousands):

			Fair Value Measurements at June 30, 2012 using:
	Total carrying value at June 30, 2012		Quoted price in active markets (Level 1)		Significant other observable inputs (Level 2)		Significant unobservable inputs (Level 3)

			Fair Value Measurements at September 30, 2011 using:
	Total carrying value at September 30, 2011		Quoted price in active markets (Level 1)		Significant other observable inputs (Level 2)		Significant unobservable inputs (Level 3)
Cash equivalents:
Money market	$	30,474	$	30,474	$	—	$	—
Available-for-sale marketable securities:
Corporate bonds	24,171		—		24,171		—

Certificates of deposit	8,766		—		8,766		—
Government municipal bonds	15,195		—		15,195		—
Total cash equivalents and marketable securities measured at fair value	$	83,601	$	30,474	$	53,127	$	—

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 nine months ended June 30, 2012.

We had no financial assets valued with Level 3 inputs as of June 30, 2012 nor did we purchase or sell any Level 3 financial assets during the nine months ended June 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.

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. The complaint seeks monetary and non-monetary relief.  We cannot predict the outcome of this matter or estimate a range of possible 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.

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 results of operations or financial condition.

INCOME TAXES

INCOME TAXES

Income taxes have been provided at an overall effective rate of 20.6% and 31.8% for the nine month periods ended June 30, 2012 and 2011, respectively. Our effective tax rate will vary based on a variety of factors, including overall profitability, the geographical mix of income before taxes and related statutory tax rate in each jurisdiction, and discrete events, such as settlements of audits.

In the first nine months of fiscal 2012, we recorded a discrete tax benefit of $1.2 million, which included a benefit of $1.1 million recorded in the third fiscal quarter of 2012 for additional research and development tax credits identified for fiscal years ended September 30, 2009, 2010 and 2011. These additional tax credits resulted from a recently completed research and development tax credit study. During the first quarter of fiscal 2012, we recorded a discrete tax benefit of $0.1 million resulting from the release of income tax reserves due to the expiration of the statutes of limitations from various U.S. tax jurisdictions. These discrete tax benefits reduced our effective tax rate by 18.6 percentage points for the nine month period ended June 30, 2012. Our income tax rate before consideration of discrete tax benefits is higher for the nine months ended June 30, 2012 as compared to the nine months ended June 30, 2011 primarily due to expiration of the research and development tax credit on December 31, 2011 for the current fiscal year and a reduction in domestic tax benefits.

In the first quarter of fiscal 2011, we recorded a discrete tax benefit of $0.6 million. This benefit primarily resulted from the reversal of tax reserves from various jurisdictions 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 4.8 percentage points for the nine month period ended June 30, 2011 to 31.8%.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is (in thousands):

Unrecognized tax benefits as of September 30, 2011	$	2,061
Increases related to:
Prior year income tax positions	631
Decreases related to:
Prior year income tax positions	(67		)
Expiration of statute of limitations	(83		)
Unrecognized tax benefits as of June 30, 2012	$	2,542

The total amount of unrecognized tax benefits that, if recognized, would affect our effective tax rate is $2.5 million. There are no tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will increase or decrease significantly over the next 12 months.

We recognize interest and penalties related to income tax matters in income tax expense. During both the three and nine month periods ended June 30, 2012 and 2011, 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 June 30, 2012 and September 30, 2011, of $0.6 million. Our long-term income taxes payable on our condensed consolidated balance

8. INCOME TAXES (CONTINUED)

sheets includes these accrued interest and penalties in addition to the unrecognized tax benefits in the table above.

At June 30, 2012, we had approximately $17.3 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. Since 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, it is not practicable to determine the unrecognized deferred tax liability; however, based on current tax laws and structures, we do not believe this would have a material impact on our current consolidated financial position, results of operations and cash flows.

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 2007 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 2007.

Product Warranties Disclosures [Abstract]

PRODUCT WARRANTY OBLIGATION

PRODUCT WARRANTY OBLIGATION

In general, we warrant our products to be free from defects in material and workmanship under normal use and service. The warranty periods generally range from one to five years. We typically have the option to either repair or replace products we deem defective with regard to material or workmanship. Estimated warranty costs are accrued in the period that the related revenue is recognized based upon an estimated average per unit repair or replacement cost applied to the estimated number of units under warranty. These estimates are based upon historical warranty incidents and are evaluated on an ongoing basis to ensure the adequacy of the warranty accrual.

The following table summarizes the activity associated with the product warranty accrual (in thousands) and is included on our Condensed Consolidated Balance Sheets in Other Current Liabilities:

RESTRUCTURING

RESTRUCTURING

U.S. 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.

Breisach 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 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. The lease on the Breisach facility ends in July 2013. As a result of these initiatives, we recorded a total charge of $0.5 million on a pre-tax basis, which consisted of $0.4 million for employee termination costs for 25 employees and $0.1 million for asset write-downs. The restructuring charge was recorded as follows: $0.2 million in the fourth quarter of fiscal 2011, $0.2 million in the first quarter of fiscal 2012, and $0.1 million in the second quarter of fiscal 2012. The final payments were completed in April 2012.

Marketable Securities [Abstract]

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 June 30, 2012, 56 of our 72 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. At June 30, 2012 our marketable securities were (in thousands):
