ITEM 1. BUSINESS

General Background and Product Offerings

Digi International Inc. (“Digi,” “we,” “our,” or “us”) was incorporated in 1985 as a Minnesota corporation. We were reorganized as a Delaware corporation in 1989 in conjunction with our initial public offering. Our common stock is traded on the NASDAQ Global Select Market under the symbol DGII. Our World Headquarters is located at 11001 Bren Road East, Minnetonka, Minnesota 55343. The telephone number at our World Headquarters is (952) 912-3444.

We are a leading global provider of business and mission-critical machine-to-machine (M2M) and Internet of Things (IoT) connectivity products and services. We help our customers create next-generation connected products and deploy and manage critical communications infrastructures in demanding environments with high levels of security and reliability. We create secure, easy to implement embedded solutions and services to help customers build IoT connectivity. We also deploy ready to use, complete box solutions to connect remote machinery. In addition, we manage cloud services, offer professional services and complete IoT solutions. Most recently we formed a cold chain solution that offers automated wireless temperature monitoring as well as employee task management services to restaurants, convenience stores, warehouses and other businesses that have perishable or temperature sensitive goods. Our products and services are used by a wide range of businesses and institutions.

Our present portfolio primarily includes:

• Wireless and wired hardware products that have been the historical foundation of our business;

• Services include the following offerings:

◦ Digi Cold Chain Solutions is a wireless end-to-end solution that utilizes sensors, gateways and an easy-to-use software application that enables companies to monitor automatically the temperature of perishable goods effectively and economically. Our Digi Cold Chain Solutions are the result of our acquisition of Bluenica Corporation in October 2015 (see Note 2 to our Consolidated Financial Statements). On November 1, 2016, we acquired Pittsburgh-based FreshTemp, LLC (FreshTemp). This acquisition expands our offerings and customer base in this market space (see Note 19 to our Consolidated Financial Statements). FreshTemp helps organizations track the completion of employee tasks in real time via the use of software applications in which employees log their activities in real-time.

◦ Wireless Design Services provide customers with turn-key wireless networking product design, testing, and certification for a wide range of wireless technology platforms and applications to improve speed to market and reduce risk.

◦ Digi Support Services provides various levels of technical support to customers with programming and implementation challenges related to Digi products. We offer base support up to our highest level of professional support which includes implementation planning, application development, on-site support, installation and customer training. These support services help minimize design risk and ensure optimal performance.

◦ Digi Device Cloud™ and Digi Remote Manager^™ - Digi Device Cloud™ (Device Cloud) is a platform as-a-service (PaaS) offering that provides a secure environment for customers to aggregate their interaction with a large number of disparate devices and connect enterprise applications to these devices. This allows for devices to be monitored and controlled remotely and permits customers to collect, interpret and utilize data from many devices to operate their businesses efficiently and with greater ease. Digi Remote Manager™ is a complete, centralized remote device management solution that is housed on the Digi Device Cloud™ and allows customers to meet service level commitments and stay compliant with Payment Card Industry (PCI) standards. Digi Remote Manager™ also allows customers to monitor, diagnose and fix remote devices without sending a technician on site.

In October 2015, we sold our Etherios, Inc. CRM consulting services business (“Etherios”), which focused on integration and configuration of enterprise resource management (ERM) systems, including customer relationship management (CRM) systems. This part of our business principally provided integration and configuration of salesforce.com products. As a result of the sale of Etherios, we have accounted for it as a discontinued operation. Accordingly, amounts in the Consolidated Statement of Operations, the Consolidated Balance Sheets and notes thereto, for all periods affected, have been reclassified to reflect discontinued operations accounting for that business. For more information on this divestiture see Note 3 to the Consolidated Financial Statements.

Industry and Marketplace Conditions

Current Market Conditions

We believe the marketplace for IoT products and services will continue to expand generally. While we realized significant revenue growth in fiscal 2015, our business stagnated in fiscal 2016 primarily because certain significant customers of our cellular and RF products slowed their purchases of our products. While we generally expect the trend of marketplace growth to continue, it is susceptible to downturns in general economic conditions as well as uncertainty or changes in the regulatory environments. These impacts may be more pronounced in certain industries. For instance, the oil and gas marketplace for IoT networking products has been more challenging in recent years because of lower prices for these natural resources. Further, as demonstrated in fiscal 2016, our own ability to grow our core hardware business can be subject to fluctuation. Sales of many of our products are subject to large non-repeatable customer deployments. If we are unable to identify and commence new deployments with equal or greater significance than completed projects, our growth from period to period may be inconsistent. In turn, if we do not replace significant opportunities as they conclude with similar opportunities of scale, our growth from period to period may be inconsistent.

Strategy

Current Status of Our Business

Since appointing Ronald E. Konezny as our Chief Executive Officer in December, 2014, we have focused on:

• Simplifying our operations;

• Improving our operating expense model and profitability; and

• Exploring ways to drive greater revenue growth.

Among other actions we have taken to advance these aims during that time include:

• We have taken steps to contain our operating expenses and delivered higher levels of profitability despite decreased revenue in fiscal 2016.

• We focused our business and improved our operating model by selling our Etherios CRM consulting business in October 2015. We acquired Etherios with the expectation that it would drive engagements with companies that utilize the salesforce.com platform and were looking to deploy solutions within their businesses. We were not, however, rewarded in the marketplace as we had hoped. As a result, we disposed of a consulting business that was losing money and not fully tied to our core hardware expertise.

• We have consolidated and relocated office locations. In the first quarter of fiscal 2016, we moved our Wireless Design Services team from an office in downtown Minneapolis to our World Headquarters in suburban Minnetonka. At first, this move was disruptive for some employees of the Wireless Design Services team and the revenues of the business

2

consequently suffered due to attrition. However, as of the fourth quarter of fiscal 2016 business results have begun to rebound. Additionally, we closed our office location in Dortmund, Germany in the third quarter of fiscal 2016 and moved the corresponding positions to our existing office in Munich, Germany. These moves improved our operating expenses and better positions our employees to drive positive results in our operations through increased collaboration. We also expect to benefit from closer proximity to certain key customers in the Munich area.

• During fiscal 2016, we continued to reduce the number of hardware product stock keeping units (SKUs) we produce. We expect this effort to simplify our operations will have a significant impact on our ability to manage inventory effectively, improve channel stocking strategies and control costs. At present, SKUs have been reduced from close to 5,000 to approximately 2,700.

• Our recent acquisitions enhance our opportunity to develop a high-growth hardware enabled service business with significant recurring revenue potential. In October 2015, we acquired Bluenica Corporation, a company focused on automating temperature monitoring of perishable goods in the food industry by using wireless sensors and a web-based application. In November 2016, we also acquired Pittsburgh-based FreshTemp, LLC. See "Acquisitions and Dispositions" below for further discussion. These acquisitions will provide us with an advanced portfolio of products for the cold chain market.

Long Term Strategy

We are focused on creating a high-growth business that leverages our long-term strengths of providing reliable and secure equipment and solutions for the M2M marketplace. We intend to continue to take steps to simplify our operations, improve operating expenses to increase our profit leverage and expand our business in ways that we believe can drive growth. We will continue to seek and evaluate acquisitions that will further enhance Digi Cold Chain Solutions as we believe this marketplace offers a path to a significant base of recurring revenue that can provide both stability and significant growth for us. If opportunities present themselves, we may also seek to acquire hardware or other businesses that we believe can improve our market position in our core IoT hardware business.

Acquisitions and Dispositions

Acquisitions

In October 2015, we acquired Bluenica Corporation, a company focused on temperature monitoring of perishable goods in the food industry by using wireless sensors which are installed in grocery and convenience stores, restaurants, and in products during shipment and storage to ensure that quality, freshness and public health requirements are met (see Note 2 to our Consolidated Financial Statements). 

This Company formed the initial basis for Digi Cold Chain Solutions and was purchased for several reasons. First, it provided us with the opportunity to develop a recurring revenue business that is focused on a large addressable market that has not been penetrated significantly. Restaurants, pharmacies, hospitals and other businesses that maintain significant inventories of perishable goods are an enormous market. These businesses by and large presently rely primarily on employees to log the temperature of these goods periodically using pencil and paper. This is not as cost effective or secure as using wireless communications sensors to provide real time alerts at all times. Second, at present this marketplace primarily is served by smaller companies that lack the infrastructure to provide hardware enabled service to customers in as effective and efficient a manner as we are able to do because of our long-standing history as an IoT hardware provider. Third, we believe customers in this marketplace will not require significant customization or development of existing products before they will commit to purchase the solution. This differs from many of our present customers who often ask us to create a highly customized product that cannot be easily sold to other parties. This potential for repeatable sales of an established product suite appeals to us. Fourth, by protecting valuable goods that impact health and safety, the solution provides a clear return on investment for potential customers whose business and reputation is highly reliant on maintaining inventory that is safe for human consumption.

We have further enhanced Digi Cold Chain Solutions with the November 1, 2016 acquisition of Pittsburgh based FreshTemp, LLC (FreshTemp). FreshTemp offers restaurants, convenience stores and other retailers the ability to monitor the temperature of food products automatically through the use of wireless sensors. The company also enables these businesses to track in real time the completion of operational tasks by their employees that could impact human health and safety - a capability that we believe enhances our product offering.

Disposition

On October 23, 2015, we entered into a stock purchase agreement with West Monroe Partners, LLC, pursuant to which they acquired our Etherios CRM consulting services business. We sold Etherios as part of a strategy to focus on providing highly reliable machine connectivity solutions for business and mission-critical application environments (see Note 3 to our Consolidated Financial Statements).

These are the only acquisitions and dispositions we have completed in the past five years. We will continue to evaluate strategic opportunities to acquire businesses as they arise and may seek to divest businesses or assets we no longer consider appropriate to our long-term strategy.

Sales Channels

We sell our products through a global network of distributors, systems integrators and value added resellers (VARs) which accounted for 66.1%, 61.8% and 63.0% of our total revenue in fiscal 2016, 2015 and 2014, respectively. We also complete sales through our own dedicated sales organization to original equipment manufacturers (OEMs) and other customers which accounted for 33.9%, 38.2% and 37.0% of our total revenue in fiscal 2016, 2015 and 2014, respectively.

Distributors

Our larger distributors, based on sales we make to them, include Alcom Electronics BV, Anewtech Systems Pte Ltd., Arrow Electronics, Inc., Astone Technologies, Atlantik Elektronik GmbH, Avnet, Codico GmbH, Digi-Key Corporation, Express Systems & Peripherals, Future Electronics, Ingram Micro, Melchoni S.p.A., Miel, Mouser Electronics, Novotech, Sapply Pty. Ltd., Scansource Corporation, Solid State Supplies, Ltd., Sphinx Computer Vertriebs GmbH, Synnex, Tech Data Corporation and Tokyo Electron Device Ltd.  We also maintain relationships with many other distributors in the U.S., Canada, Europe, Asia Pacific and Latin America.

Strategic Sales Relationships

We maintain alliances with other industry leaders to develop and market technology solutions. These include many major communications hardware and software vendors, operating system suppliers, computer hardware manufacturers, enterprise application providers and cellular carriers. Among others, partners include: AT&T, Bell Mobility, Ericsson, NXP, Qualcomm, Telit, Rogers, Silicon Laboratories, Sprint, Telus, Verizon and several other cellular carriers worldwide. Furthermore, we maintain a worldwide network of authorized developers that extends our reach into certain other technology applications and geographical regions.

We have established relationships with equipment vendors in a range of industries such as energy, industrial, retail, transportation, medical, and government that allow the vendors to ship our products and services as component parts of their overall solutions. Our products are used by many of the world’s leading telecommunications companies and Internet service providers, including AT&T Inc., Sprint Corporation and Verizon Communications Inc.

No single customer comprised more than 10% of our consolidated revenue for any of the years ended September 30, 2016, 2015 or 2014.

Competition

We compete primarily in the communications technology industry, which is characterized by rapid technological advances and evolving industry standards. The market can be affected significantly by new product introductions and marketing activities of industry participants. In addition, we may compete with other companies to acquire new businesses or technologies and the competition to secure such assets may be intense. We compete for customers on the basis of existing and planned product features, service and software application capabilities, company reputation, brand recognition, technical support, alliance relationships, quality and reliability, product development capabilities, price and availability. While no competitor offers a comparable range of products and services, various companies do compete with us with respect to one or more of our products or solutions. With respect to many of our product and service offerings, we face competition from companies who dedicate more resources and attention to that particular offering than we are able to do given the breadth of our business. As marketplace for IoT connectivity products and solutions continues to grow, we expect to encounter increased competition. Some of these competitors may have access to significantly more financial and technical resources than we possess.

Manufacturing Operations

Our manufacturing operations are conducted through a combination of internal manufacturing and external subcontractors specializing in various parts of the manufacturing process.  We rely on third party foundries for our semiconductor devices that are Application Specific Integrated Circuits (ASICs) and we outsource printed circuit board production.  This approach allows us to reduce our fixed costs, maintain production flexibility and optimize our profits.

Our products are manufactured to our designs with standard and custom components. Most of the components are available from multiple vendors. We have several single-sourced supplier relationships, either because alternative sources are not available or because the relationship is advantageous to us. If these suppliers are unable to provide a timely and reliable supply of components, we could experience manufacturing delays that could adversely affect our consolidated results of operations in a material way.

Seasonality

In general, our business is not considered to be highly seasonal, although our first fiscal quarter revenue is often less than other quarters due to holidays and fewer shipping days.

Working Capital

We fund our business operations through a combination of cash and cash equivalents, marketable securities and cash generated from operations. We believe that our current financial resources, cash generated from operations, and our capacity for debt and/or equity financing will be sufficient to fund our business operations for the next twelve months and beyond.

Research & Development and Intellectual Property Rights

During fiscal years 2016, 2015 and 2014, our research and development expenditures were $31.0 million, $29.9 million and $28.9 million, respectively.

Due to rapidly changing technology in the communications technology industry, we believe a large part of our success depends upon the product and service development skills of our personnel as well as our ability to integrate any acquired technologies with organically developed technologies. While we dedicate significant resources to research and development, many of our competitors are focused on a smaller set of products than us and are likely able to dedicate more resources than us toward the portions of the market in which we compete.

Our proprietary rights and technology are protected by a combination of copyrights, patents, trade secrets and trademarks.

We have established common law and registered trademark rights on a family of marks for a number of our products. Our products and services primarily are sold under the Digi, Rabbit® and Xbee® brands. We believe that the Digi and Rabbit® brands have established strong identities with our targeted customer base and our customers associate the Digi brand with “reliability” and the Rabbit® brand with “ease of integration.” We believe that our customers associate Xbee® with “ease of use.” Many of our customers choose us because they are building a very complex system solution and they want the highest level in product reliability and ease of integration and use. Our Etherios® brand was sold in connection with the sale of Etherios, Inc. in October 2015.

Our patents are applicable to specific technologies and are valid for varying periods of time based on the date of patent application or patent grant in the U.S. and the legal term of patents in the various foreign countries where patent protection is obtained. We believe our intellectual property has significant value and is an important factor in the marketing of our company and products.

Backlog

Backlog as of September 30, 2016 and 2015 was $25.3 million and $27.2 million, respectively. The majority of the backlog at September 30, 2016 is expected to be shipped in fiscal 2017. Backlog as of any particular date is not necessarily indicative of our future sales trends.

Employees

We had 515 employees on September 30, 2016. We consider our relations with our employees to be good.

5

Geographic Areas and Currency Risks

Our customers are located throughout North America, Europe, Middle East & Africa (EMEA), Asia Pacific and Latin America. We are exposed to foreign currency transaction risk associated with certain sales being denominated in Euros, British Pounds, Japanese Yen and Canadian Dollar 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 manage our net asset or net liability position for U.S. dollar accounts in our foreign locations to reduce our foreign currency risk. We have not implemented a formal hedging strategy to reduce foreign currency risk.

During 2016, we had approximately $71.5 million of revenue related to foreign customers including export sales, of which $22.9 million was denominated in foreign currency, predominantly the Euro and British Pound. During fiscal 2015 and 2014, we had approximately $76.2 million and $76.3 million, respectively of revenue to foreign customers including export sales, of which $21.3 million and $23.3 million, respectively, were denominated in foreign currency, predominantly the Euro and British Pound. In future periods, we expect a significant portion of sales will continue to be made in Euros and British Pounds.

Financial information about geographic areas appears in Note 5 to our Consolidated Financial Statements in this Form 10-K.

PRINCIPAL HARDWARE PRODUCTS AND SERVICES

Hardware Products

Cellular routers and gateways - Cellular routers provide connectivity for devices over a cellular data network. They can be used as a cost effective alternative to landlines for primary or backup connectivity for remote locations and devices. These products have been certified by the major wireless providers in North America and abroad, including, among others, AT&T®, Verizon Wireless®, Sprint®, Bell Mobility, Rogers and Vodafone.Cellular gateway products enable devices or groups of devices to be networked in locations where there is no existing network or where access to a network is prohibited.

ITEM 1A. RISK FACTORS

Multiple risk factors exist which could have a material effect on our operations, results of operations, financial position, liquidity, capital resources and common stock.

Risks Relating to Our Business

We face intense competition from established companies that may have significant advantages over us and our products.

The market for our products is intensely competitive. Certain of our competitors and potential competitors have or may develop greater financial, technological, manufacturing, marketing, and personnel resources than us either generally or relative to the product sets they sell in competition to us. Further, there are numerous companies competing with us in various segments of the market for our products, and their products may have advantages over our products in areas such as conformity to existing and emerging industry standards, interoperability with other products, management and security capabilities, performance, price, ease of use, scalability, reliability, flexibility, product features and technical support.

Our current and potential competitors have or may develop one or more of the following significant advantages over us in the product areas where they compete with us:

• tighter focus on an individual product or product category;

• greater financial, technical and marketing resources;

• barriers to transition to our products;

• higher brand recognition across larger geographic regions;

• more comprehensive functionality;

• longer-standing cooperative relationships with OEM and end-user customers;

• superior customer service capacity and quality;

• longer operating history; and

• larger customer base.

7

We cannot provide assurance that we will be able to compete successfully with our current and potential competitors. Such competitors may be able to more quickly develop or adapt to new or emerging technologies and changes in customer requirements, or devote greater resources to the development, promotion and sale of their products. Additionally, it is probable that new competitors or new alliances among existing competitors could emerge and rapidly acquire significant market share.

Our dependence on new product development and the rapid technological change that characterizes our industry makes us susceptible to loss of market share resulting from competitors’ product introductions and enhancements, service capabilities and similar risks.

Our industry is characterized by rapidly changing technologies, evolving industry standards, frequent new product introductions, short product life cycles in certain instances and rapidly changing customer requirements. The introduction of products and enhancements embodying new technologies and the emergence of new industry standards can render existing products obsolete and unmarketable.

Our future success will depend on our ability to enhance our existing products, to introduce new products to meet changing customer requirements and emerging technologies, and to demonstrate the performance advantages and cost-effectiveness of our products over competing products. Failure by us to modify our products to support new alternative technologies or failure to achieve widespread customer acceptance of such modified products could cause us to lose market share and cause our revenue to decline. Further, if competitors offer better service capabilities associated with the implementation and use of products in communication networks, our business could be impacted negatively.

We may experience delays in developing and marketing product enhancements or new products that respond to technological change, evolving industry standards and changing customer requirements. There can be no assurance that we will not experience difficulties that could delay or prevent the successful development, introduction, and marketing of these products or product enhancements, or that our new products and product enhancements will meet the requirements of the marketplace adequately and achieve any significant or sustainable degree of market acceptance in existing or additional markets. In addition, the future introductions or announcements of products by us or one of our competitors embodying new technologies or changes in industry standards or customer requirements could render our then-existing products obsolete or unmarketable. This risk may become more pronounced as new competitors enter the marketplace, especially if these competitors have more resources than us to develop and market new products and technologies and provide related services. There can be no assurance that the introduction or announcement of new product offerings by us or one or more of our competitors will not cause customers to defer their purchase of our existing products, which could cause our revenue to decline.

We intend to continue to devote significant resources to our research and development, which, if not successful, could cause a decline in our revenue and harm our business.

We intend to continue to devote significant resources to research and development in the coming years to enhance and develop additional products. For fiscal 2016, 2015, and 2014, respectively, our research and development expenses were 15.2%, 14.7% and 15.8% of our revenue. If we are unable to develop new products, applications and services as a result of our research and development efforts, if we encounter delays in deploying these new products, applications and services, or if the products, applications and services we develop are not successful, our business could be harmed. Even if we develop new products, applications and services that are accepted by our target markets, the net revenue from these products, applications and services may not be sufficient to justify our investment in research and development.

Many of our products, applications and services have been developed through a combination of internally developed technologies and acquired technologies. Our ability to continue to develop new products, applications and services could be partially dependent on finding and acquiring new technologies in the marketplace. Even if we identify new technologies that we believe would be complementary to our internally developed technologies, we may not be successful in obtaining those technologies or we may not be able to acquire the technologies at a price that is acceptable to us.

A substantial portion of our development efforts have been directed toward the development of new products targeted to manufacturers of intelligent, network-enabled devices and other embedded systems in various markets, including markets in which networking solutions for embedded systems have not historically been sold, such as markets for industrial automation equipment and medical equipment.

Our participation in a services and solutions model, using hardware and cloud-based services, presents execution and competitive risks.

We are deploying a services and solutions model. Our Digi Cold Chain offering deploys hardware, software and cloud-based hosting. In other parts of our business we also offer our own internally developed hosted services and cloud-based platform,

8

software applications, and supporting products and services. We are employing significant human and financial resources to develop and deploy these offerings. As we work to grow and scale these offerings, these investments have impacted our gross margins and profitability adversely in the past and may continue to do so in the future. While we believe we have a strong foundation to compete, it is uncertain whether our strategies will attract the users or generate the revenue required to be successful. We have and will encounter competition from other solutions providers, many of whom may have more significant resources than us with which to compete. Whether we are successful in this business model depends on a number of factors, including:

• our ability to put in place the infrastructure to deploy and evolve our solutions effectively and continuously;

• the features and functionality of our offerings relative to competing offerings as well as our ability to market effectively;

• our ability to engage in successful strategic relationships with third parties such as telecommunications carriers, component makers and systems integrators;

• competing effectively for market share; and

• deploying complete end-to-end solutions that meet the needs of the marketplace generally as well as the particular requirements of our customers more effectively and efficiently than competitive solutions.

Our ability to sustain and grow our business depends in large part on the success of our channel partner distributors and resellers.

A substantial part of our revenue is generated through sales by channel partner distributors and resellers. Sales through our channel partners accounted for 66.1%, 61.8% and 63.0% of our total revenue in fiscal 2016, 2015 and 2014, respectively. Further, in recent years we have been taking steps to expand our relationship with certain distributors who have global reach, an effort that may increase the percent of our revenue driven through channel partners or our reliance on certain channel partners to drive sales. To the extent our channel partners are unsuccessful in selling our products or if we are unable to obtain and retain a sufficient number of high-quality channel partners, our operating results could be materially and adversely affected. In addition, our channel partners may also market, sell and support products and services that are competitive with ours, and may devote more resources to the marketing, sales and support of such products. They also may have incentives to promote our competitors’ products in lieu of our products, particularly for our competitors with larger volumes of orders, more diverse product offerings and a longer relationship with our distributors and resellers. In these cases, one or more of our important channel partners may stop selling our products completely. Our channel partner sales structure also could subject us to lawsuits, potential liability and reputational harm if, for example, any of our channel partners misrepresents the functionality of our products or services to customers, or violates laws or our corporate policies. If we fail to manage our existing or future sales channel partners effectively, our business and operating results could be materially and adversely affected.

Our gross margins may be subject to decline.

Our gross margins may be subject to decline which could decrease our overall profitability and impact our financial performance adversely.  Many of the hardware products we sell are approaching the end of their product life cycles.  These mature hardware products typically sell at higher gross margins than our other product and service offerings.  In fiscal 2016, sales of mature hardware products represented about 40.9% of our overall revenue. While these products experienced increased sales in fiscal 2016, in general, revenues from the sale of these mature hardware products have been declining for several years at a rate of between 1% and 10%, and we expect this trend to continue.  In addition, ongoing cost pressures in our industry create downward pressure on the prices at which we and other manufacturers can sell hardware products.  We also have indicated that we would be willing to realize lower levels of gross margins from customers in return for long-term, binding purchase commitments, a strategy that, if successful, could also put downward pressure on our gross margins. While part of our longer term strategy is to sell software applications and IoT solutions such as Digi Cold Chain which can provide recurring revenues at relatively high gross margin, these types of offerings are at early stages of adoption by customers and their sales growth is not necessarily predictable or assured.  As such, our gross margins may be subject to decline unless we can implement cost reduction initiatives effectively to offset the impact of these factors.

Our revenue may be subject to fluctuations based on the level of significant one time purchases.

No single customer has represented more than 10% of our revenue in any of the last three fiscal years. However, many of our customers make significant one-time hardware purchases for large projects that are not repeated. As a result, our revenue may be subject to significant fluctuations based on whether we are able to close significant sales opportunities. Our failure to

9

complete one or a series of significant sales opportunities in a particular fiscal period could have a material adverse effect on our revenue for that period.

Certain of our products are sold into mature markets, which could limit our ability to continue to generate revenue from these products.

Many of our hardware products are sold into mature markets that are characterized by a trend of declining demand.  As the overall market for these mature hardware products decreases due to the adoption of new technologies, we expect that our revenue from these products will continue to decline.  As a result, our future prospects depend in part on our ability to acquire or develop and successfully market additional products that address growth markets.

Our ability to grow our business is dependent in part on strategic relationships we develop and maintain with third parties as well as our ability to integrate and assure use of our products and services in coordination with the products and services of certain strategic partners in a commercially acceptable manner.

We believe that our ability to increase our sales depends in part on maintaining and strengthening relationships with parties such as telecommunications carriers, systems integrators, enterprise application providers, component providers and other strategic technology companies. Once a relationship is established, we likely will dedicate significant time and resources to it in an effort to advance our business interests and there is no assurance any strategic relationship will generate enough revenue to offset the significant resources we use to advance the relationship. Parties with whom we establish strategic relationships may also work with companies that compete with us. We also have limited, if any, control as to whether these parties devote adequate resources to promoting, selling, and implementing our products. Further, new or emerging technologies, technological trends or changes in customer requirements may result in certain companies with whom we maintain strategic relationships de-emphasizing their dealings with us or becoming potential competitors in the future. We also have limited, if any, control as to other business activities of these parties and we could experience reputational harm because of our association with such parties if they fail to execute on business initiatives, are accused of breaking the law or otherwise suffer reputational harm for other reasons. All of these factors could materially and adversely impact our business and results of operations.

In some cases we expect the establishment of a strategic relationship with a third party to result in integrations of our products or services with those of other parties. Identifying appropriate parties for these relationships as well as negotiating and documenting business agreements with them requires significant time and resources. We expect these agreements typically to be non-exclusive and not to prohibit the other party from working with our competitors or offering competing services. Once the relationship is established we may also encounter difficulties in combining our products and services in a commercially acceptable manner. We expect this type of dynamic, whereby our ability to realize sales opportunities is dependent on how our products and services interact with those sold by third parties, may become more common as the marketplace in our industry evolves. There can be no guarantee in any particular instance that we will be successful in making our products interact with those of other parties in a commercially acceptable manner and, even if we do, we cannot guaranty the resulting products and services will be marketed or sold effectively via the relationship.

Our failure to compete successfully in our highly competitive market could result in reduced prices and loss of market share.

The market in which we operate is characterized by rapid technological advances and evolving industry standards. The market can be affected significantly by new product introductions and marketing activities of industry participants. In addition, the amount of competition we face in the marketplace may change and grow as the market for our industry grows and new entrants enter the marketplace. Present and future competitors may be able to identify new markets and develop products more quickly, which are superior to those developed by us. They may also adapt new technologies faster, devote greater resources to research and development, promote products more aggressively, and price products more competitively than us. Competition may also intensify or we may no longer be able to compete effectively in the markets in which we compete.

Our failure to anticipate or manage product transitions effectively could have a material adverse effect on our revenue and profitability.

From time to time, we or our competitors may announce new products, capabilities, or technologies that may replace or shorten the life cycles of our existing products. Announcements of currently planned or other new products may cause customers to defer or stop purchasing our products until new products become available. Furthermore, the introduction of new or enhanced products requires us to manage the transition from older product inventories and ensure that adequate supplies of new products can be delivered to meet customer demand. Our failure to anticipate the revenue declines associated with older products or manage transitions from older products effectively could result in inventory obsolescence and also have a material adverse effect on our revenue and profitability.

10

Acquisitions could disrupt our business and seriously harm our financial condition.

We will continue to consider acquisitions of complementary businesses, products or technologies. In the event of any future acquisitions, we could issue stock that would dilute our current stockholders’ percentage ownership, incur debt, assume liabilities, or incur large and immediate write-offs.

Our operation of any acquired business also involves numerous risks, including but not limited to:

• problems combining the purchased operations, technologies, or products;

• unanticipated costs;

• diversion of management’s attention from our core business;

• difficulties integrating businesses in different countries and cultures;

• adverse effects on existing business relationships with suppliers and customers;

• risks associated with entering markets in which we have no or limited prior experience; and

• potential loss of key employees, particularly those of the purchased organization.

We cannot assure that we will be able to successfully integrate any businesses, products, technologies, or personnel that we have acquired or that we might acquire in the future and any failure to do so could disrupt our business and have a material adverse effect on our consolidated financial condition and results of operations. Moreover, from time to time, we may enter into negotiations for a proposed acquisition, but be unable or unwilling to consummate the acquisition under consideration. This could cause significant diversion of management’s attention and out-of-pocket expenses for us. We could also be exposed to litigation as a result of any consummated or unconsummated acquisition.

We are subject to various cybersecurity risks, which are particularly acute in the cloud-based technologies operated by us and other third parties that form a part of our solutions. These risks may increase our costs and could damage our brand and reputation.

As we continue to direct a substantial portion of our sales and development efforts toward broader based solutions, such as Digi Cold Chain Solutions and the Device Cloud, we expect to store, convey and potentially process significant amounts of data produced by devices. This data may include confidential or proprietary information, intellectual property or personally identifiable information of our customers or other third parties with whom they do business.  It is important for us to maintain solutions and related infrastructure that are perceived by our customers and other parties with whom we do business to provide a reasonable level of reliability and security.  Despite available security measures and other precautions, the infrastructure and transmission methods used by our products and services may be vulnerable to interception, attack or other disruptive problems.  Continued high-profile data breaches at other companies evidence an external environment that is becoming increasingly hostile to information security.  Improper disclosure of data or perception that our data security is insufficient could harm our reputation, give rise to legal proceedings, or subject our company to liability under laws that protect data, any of which could result in increased costs and loss of revenue.

If a cyberattack or other security incident were to allow unauthorized access to or modification of our customers’ data or our own data, whether due to a failure with our systems or related systems operated by third parties, we could suffer damage to our brand and reputation. The costs we would incur to address and fix these incidents could significantly increase our expenses. These types of security incidents could also lead to lawsuits, regulatory investigations and increased legal liability, including in some cases contractual costs related to customer notification and fraud monitoring. Further, as regulatory focus on privacy and data security issues continues to increase and worldwide laws and regulations concerning the protection of information become more complex, the potential risks and costs of compliance to our business will intensify.

11

Digi Cold Chain Solutions is a new business line for us and is subject to the risks faced by a new business.

Digi Cold Chain Solutions was formed through acquisitions of various businesses and represents a new business line for our company. Our management has limited experience in this marketplace. The operation of Digi Cold Chain Solutions will be subject to significant additional risks that are not necessarily related to our legacy products and services. Additional risks that relate to Digi Cold Chain Solutions, include, but are not limited to:

• We have not traditionally sold products or services to restaurants, pharmacies, hospitals and other similar businesses, which are a focus for Digi Cold Chain Solutions.

• Digi Cold Chain Solutions offerings are deployed to help assure perishable goods are safely preserved. This presents a risk of loss in the event of a malfunction or failure of our offerings.

• Although we have retained several key employees with extensive experience in operating companies we have acquired to date, Digi Cold Chain Solutions represents a new line of business in a marketplace that is nascent in its development and has numerous competitors. We cannot provide assurances we will be successful in operating and growing this business.

• Our ability to succeed with the Digi Cold Chain Solutions offerings will depend in large part on our ability to provide customers with hardware and software products that are easy to deploy and offer features and functionality that address the needs of particular businesses. We may face challenges and delays in the development of this business as the marketplace for products and services evolves to meet the needs and desires of customers.

In light of these risks and uncertainties, we may not be able to establish or maintain Digi Cold Chain Solutions’ market share, integrate it successfully into our other operations or take full advantage of businesses we have acquired or may acquire in the future. There can be no assurance that we will recover our investments in this new business, that we will realize a profit from this new business or that diverting our management’s attention to this new business will not have a material adverse effect on our existing businesses, any of which may have a material adverse effect on our results of operations, financial condition and prospects.

We have identified a material weakness in our internal control over financial reporting. If we are unable to sufficiently mitigate the material weakness or if we fail to establish and maintain effective internal control over financial reporting, our ability to accurately report our financial results could be adversely affected.

In connection with the preparation of our consolidated financial statements as of and for the year ended September 30, 2016, our management conducted an assessment of the effectiveness of our internal control over financial reporting. In connection with that assessment, we concluded there is a material weakness in our internal control over financial reporting with respect to the design of access control reviews for our financial system and related independent reviews of manual journal entry inputs to the system. The Exchange Act Rule 12b-2 and Rule 1-02(p) of Regulation S-X define a material weakness as a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected and corrected on a timely basis. The identified material weakness is further described in Part II, Item 9A of this Form 10-K.

Our remediation efforts with regard to the material weakness are also described in Part II, Item 9A of this Form 10-K. Although we expect to remediate the material weakness by the end of our second fiscal quarter of 2017, we cannot be certain whether or when our remediation initiatives will be successful. If our remedial measures are insufficient to address the material weakness or if additional material weaknesses in our internal control over financial reporting are discovered or occur in the future, our consolidated financial statements may contain material misstatements and we could be required to restate our financial results. Further, regardless of how well designed, operated and evaluated it may be, any system of internal control over financial reporting can provide only reasonable, not absolute, assurance that its objective will be satisfied. We cannot be certain that, in the future, additional material weaknesses will not exist or otherwise be discovered. If we fail to maintain effective internal control over financial reporting, the accuracy and timing of our financial reporting may be adversely affected by misstatements or restatements of our consolidated financial statements, our business and financial condition could be harmed, investors may lose confidence in our reported financial information and the market price of our securities may decline.

Our consolidated operating results and financial condition may be adversely impacted by worldwide economic conditions and credit tightening.

If worldwide economic conditions experience a significant downturn, these conditions may make it difficult or impossible for our customers and suppliers to accurately forecast and plan future business activities, which may cause them to slow or suspend spending on products and services. Our customers may find it difficult to gain sufficient credit in a timely manner, which could

12

result in an impairment of their ability to place orders with us or to make timely payments to us for previous purchases. If this occurs, our revenue may be reduced, thereby having a negative impact on our results of operations. In addition, we may be forced to increase our allowance for doubtful accounts and our days sales outstanding may increase, which would have a negative impact on our cash position, liquidity and financial condition. We cannot predict either the timing or duration of an economic downturn in the economy, should one occur.

The long and variable sales cycle for certain of our products makes it more difficult for us to predict our operating results and manage our business.

The sale of our products and services can involve a significant technical evaluation and commitment of capital and other resources by potential customers and end users, as well as delays frequently associated with end users’ internal procedures to deploy new technologies within their products and to test and accept new technologies. For these and other reasons, the sales cycle associated with certain of our products is typically lengthy and is subject to a number of significant risks, such as end users’ internal purchasing reviews, that are beyond our control. Because of the lengthy sales cycle and the large size of certain customer orders, if orders forecasted for a specific customer are not realized or delayed, our operating results could be materially adversely affected.

We depend on manufacturing relationships and on limited-source suppliers, and any disruptions in these relationships may cause damage to our customer relationships.

We procure all parts and certain services involved in the production of our products and subcontract most of our product manufacturing to outside firms that specialize in such services. Although most of the components of our products are available from multiple vendors, we have several single-source supplier relationships, either because alternative sources are not available or because the relationship is advantageous to us. There can be no assurance that our suppliers will be able to meet our future requirements for products and components in a timely fashion. In addition, the availability of many of these components to us is dependent in part on our ability to provide our suppliers with accurate forecasts of our future requirements. Delays or lost revenue could be caused by other factors beyond our control, including late deliveries by vendors of components, or force majeure events. For instance, a fire in November 2014 disrupted the operations at one of our contract manufacturers in Thailand. If we are required to identify alternative suppliers for any of our required components, qualification and pre-production periods could be lengthy and may cause an increase in component costs and delays in providing products to customers. Any extended interruption in the supply of any of the key components currently obtained from limited sources could disrupt our operations and have a material adverse effect on our customer relationships and profitability.

Our inability to obtain the appropriate telecommunications carrier certifications or approvals from governmental regulatory bodies could impede our ability to grow revenue in our wireless products.

The sale of our wireless products in certain geographical markets is sometimes dependent on the ability to gain telecommunications carrier certifications and/or approvals by certain governmental bodies.  Failure to obtain these approvals, or delays in receiving the approvals, could impact our ability to enter our targeted markets or to compete effectively or at all in these markets and could have an adverse impact on our revenue.

We are dependent on wireless communication networks owned and controlled by others.

Our revenue could decline if we are unable to deliver continued access to digital cellular wireless carriers that we depend on to provide sufficient network capacity, reliability and security to our customers. Our financial condition could be impacted if our wireless carriers were to increase the prices of their services, or to suffer operational or technical failures.

The impact of natural disasters could negatively impact our supply chain and customers resulting in an adverse impact to our revenue and profitability.

Certain of our components and other materials used in producing our products are from regions susceptible to natural disasters. If we are unable to procure necessary materials, we could experience a disruption to our supply chain that would hinder our ability to produce our products in a timely manner, or cause us to seek other sources of supply, which may be more costly or which we may not be able to procure on a timely basis. We also risk damage to any tooling, equipment or inventory at the supplier’s facilities. For instance, flooding in October 2011 and a fire in November 2014 disrupted the operations at one of our contract manufacturers in Thailand. In addition, our customers may not follow their normal purchasing patterns or temporarily cease purchasing from us due to impacts to their businesses in the region, creating unexpected fluctuations or decreases in our revenue and profitability. Natural disasters in other parts of the world on which our operations are reliant also could have material adverse impacts on our business.

13

Our use of suppliers in other parts of the world involves risks that could negatively impact us.

We purchase a number of components from suppliers in other parts of the world. Product delivery times may be extended due to the distances involved, requiring more lead time in ordering. In addition, ocean freight delays may occur as a result of labor problems, weather delays or expediting and customs issues. Any extended delay in receipt of the component parts could eliminate anticipated cost savings and have a material adverse effect on our customer relationships and profitability.

Our ability to compete could be jeopardized if we are unable to protect our intellectual property rights.

Our ability to compete depends in part on our proprietary rights and technology. Our proprietary rights and technology are protected by a combination of copyrights, patents, trade secrets and trademarks.

We enter into confidentiality agreements with our employees, and sometimes with our customers, potential customers and other third parties, and limit access to the distribution of our proprietary information. There can be no assurance that the steps taken by us in this regard will be adequate to prevent the misappropriation of our technology. Our pending patent applications may be denied and any patents, once issued, may be circumvented by our competitors. Furthermore, there can be no assurance that others will not develop technologies that are superior to our technologies. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or to obtain and use information that we regard as proprietary. In addition, the laws of some foreign countries do not protect our proprietary rights as fully as do the laws of the United States. There can be no assurance that our means of protecting our proprietary rights in the United States or abroad will be adequate or that competing companies will not independently develop similar technologies. Our failure to adequately protect our proprietary rights could have a material adverse effect on our competitive position and result in loss of revenue.

From time to time, we are subject to claims and litigation regarding intellectual property rights or other claims, which could seriously harm us and require us to incur significant costs.

The communications technology industry is characterized by frequent litigation regarding patent and other intellectual property rights. From time to time, we receive notification of a third-party claim that our products infringe other intellectual property rights. Any litigation to determine the validity of third-party infringement claims, whether or not determined in our favor or settled by us, may be costly and divert the efforts and attention of our management and technical personnel from productive tasks, which could have a material adverse effect on our ability to operate our business and service the needs of our customers. There can be no assurance that any infringement claims by third parties, regardless if they have merit, will not materially adversely affect our business, operating results or financial condition. In the event of an adverse ruling in any such matter, we may be required to pay substantial damages, cease the manufacture, use and sale of infringing products, discontinue the use of certain processes or be required to obtain a license under the intellectual property rights of the third party claiming infringement. There can be no assurance that a license would be available on reasonable terms or at all. Any limitations on our ability to market our products, or delays and costs associated with redesigning our products or payments of license fees to third parties, or any failure by us to develop or license a substitute technology on commercially reasonable terms could have a material adverse effect on our business, operating results and financial condition.

We face risks associated with our international operations and expansion that could impair our ability to grow our revenue abroad as well as our overall financial condition.

We believe that our future growth is dependent in part upon our ability to increase sales in international markets. These sales are subject to a variety of risks, including fluctuations in currency exchange rates, tariffs, import restrictions and other trade barriers, unexpected changes in regulatory requirements, longer accounts receivable payment cycles, potentially adverse tax consequences, and export license requirements. In addition, we are subject to the risks inherent in conducting business internationally, including political and economic instability and unexpected changes in diplomatic and trade relationships. In many markets where we operate business and cultural norms are different than those in the United States and practices that may violate laws and regulations applicable to us like the Foreign Corrupt Practices Act (FCPA) and the UK Anti-Bribery Act (UKBA) are more commonplace. Although we have implemented policies and procedures with the intention of ensuring compliance with these laws and regulations, our employees, contractors and agents, as well as channel partners involved in our international sales, may take actions in violation of our policies. Many of our vendors and strategic business allies also have international operations and are subject to the risks described above. Even if we are able to successfully manage the risks of international operations, our business may be adversely affected if one or more of our business partners are not able to successfully manage these risks.There can be no assurance that one or more of these factors will not have a material adverse effect on our business strategy and financial condition.

14

Our failure to comply effectively with regulatory laws pertaining to our foreign operations could have a material adverse effect on our revenue and profitability.

We are required to comply with U.S. government export regulations in the sale of our products to foreign customers, including requirements to properly classify and screen our products against a denied parties list prior to shipment. We are also required to comply with the provisions of the FCPA and all other anti-corruption laws, such as UKBA, of all other countries in which we do business, directly or indirectly, including compliance with the anti-bribery prohibitions and the accounting and recordkeeping requirements of this law. Violations of the FCPA or other similar laws could trigger sanctions, including ineligibility for U.S. government insurance and financing, as well as large fines. Failure to comply with the aforementioned regulations could also deter us from selling our products in international jurisdictions, which could have a material adverse effect on our revenue and profitability.

Foreign currency exchange rates may adversely affect our operating results.

We are exposed to a variety of market risks, including the effects of changes in foreign currency exchange rates on transactions that are denominated in foreign currencies. Because our financial statements are denominated in U.S. Dollars and approximately 11% of our revenue is denominated in a currency other than U.S. Dollars, such as Euros, British Pounds, Yen and Canadian Dollars, our revenues and earnings may be adversely impacted if the U.S. dollar strengthens significantly against these foreign currencies.

The loss of key personnel could prevent us from executing our business strategy.

Our business and prospects depend to a significant degree upon the continuing contributions of our executive officers and key technical and other personnel. Competition for such personnel is intense, and there can be no assurance that we will be successful in attracting and retaining qualified personnel. Failure to attract and retain key personnel could result in our failure to execute our business strategy.

Our failure to comply effectively with the requirements of applicable environmental legislation and regulation could have a material adverse effect on our revenue and profitability.

Production and marketing of products in certain states and countries may subject us to environmental and other regulations. In addition, certain states and countries may pass new regulations requiring our products to meet certain requirements to use environmentally friendly components. The European Union has issued two directives relating to chemical substances in electronic products. The Waste Electrical and Electronic Equipment Directive (WEEE) makes producers of certain electrical and electronic equipment financially responsible for collection, reuse, recycling, treatment and disposal of equipment placed in the European Union market. The Restrictions of Hazardous Substances Directive (RoHS) bans the use of certain hazardous materials in electric and electrical equipment which are put on the market in the European Union. In the future, China and other countries including the United States may adopt further environmental compliance programs. If we fail to comply with these regulations, we may not be able to sell our products in jurisdictions where these regulations apply, which could have a material adverse effect on our revenue and profitability.

Negative conditions in the global credit markets may impair a portion of our investment portfolio.

Our investment portfolio consists of certificates of deposit, commercial paper, money market funds, corporate bonds and government municipal bonds. These marketable securities are classified as available-for-sale and are carried at fair market value. Some of our investments could experience reduced liquidity and could result in an impairment charge should the impairment be considered as other-than-temporary. This loss would be recorded in our consolidated statement of operations, which could materially adversely impact our consolidated results of operations and financial condition.

Unanticipated changes in our tax rates could affect our future results.

Our future effective tax rates could be favorably or unfavorably affected by unanticipated changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of our deferred tax assets and liabilities, or by changes in tax laws or our interpretation of such laws. In addition, we may be subject to the examination of our income tax returns by the Internal Revenue Service and other U.S. and international tax authorities. We regularly assess the potential outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from these examinations will not have an adverse effect on our consolidated operating results and financial condition.

15

We may have additional tax liabilities.

We are subject to income taxes in the United States and many foreign jurisdictions.  Significant judgment is required in determining our worldwide provision for income taxes, including our reserves for uncertain tax positions.  In the ordinary course of business, there are many transactions and calculations where the ultimate tax determination is uncertain.  We regularly are under audit by tax authorities.  Although we believe our tax estimates are reasonable, the final determination of tax audits could be materially different from our historical income tax provisions and accruals.  The results of an audit could have a material effect on our consolidated financial position, results of operations, or cash flows in the period or periods for which that determination is made.

Risks Related to Our Common Stock

Unsolicited takeover proposals, governance change proposals, proxy contests and resulting litigation may adversely impact our operations, create uncertainty and affect the market price and volatility of our securities.

We have received an unsolicited takeover proposal and other companies in our industry have been the target of unsolicited takeover proposals in the past. In the event that a third party, such as a competitor, private equity firm or activist investor makes an unsolicited takeover proposal, or proposes to change our governance policies or board of directors, or makes other proposals concerning our ownership structure or operations, our review and consideration of such proposals may be a significant distraction for our management and employees, and could require us to expend significant time and resources. Such proposals may create uncertainty for our employees and this uncertainty may adversely affect our ability to retain key employees, to hire new talent or to complete acquisitions we may desire to make. Similar uncertainty among our customers, suppliers and other business partners could cause them to terminate, or not to renew or enter into, arrangements with us. Certain proposals may result in costly proxy contests or litigation that can disrupt our business operations or result in an adverse effect on our operating results. Management and employee distraction related to any such proposals also may adversely impact our ability to conduct our business optimally and pursue our strategic objectives. Such proposals, or their withdrawal, could create uncertainty among investors and potential investors as to our future direction and affect the market price of our common stock without regard to our operational or financial performance.

Certain provisions of the Delaware General Corporation Law and our charter documents have an anti-takeover effect.

There exist certain mechanisms under the Delaware General Corporation Law and our charter documents that may delay, defer or prevent a change of control. For instance, under Delaware law, we are prohibited from engaging in certain business combinations with interested stockholders for a period of three years after the date of the transaction in which the person became an interested stockholder unless certain requirements are met, and majority stockholder approval is required for certain business combination transactions with interested parties.

Our Certificate of Incorporation contains a “fair price” provision requiring majority stockholder approval for certain business combination transactions with interested parties, and this provision may not be changed without the vote of at least 80% of the outstanding shares of our voting stock. Other mechanisms in our charter documents may also delay, defer or prevent a change of control. For instance, our Certificate of Incorporation provides that our Board of Directors has authority to issue series of our preferred stock with such voting rights and other powers as the Board of Directors may determine. Furthermore, we have a classified board of directors, which means that our directors are divided into three classes that are elected to three-year terms on a staggered basis. Since the three-year terms of each class overlap the terms of the other classes of directors, the entire board of directors cannot be replaced in any one year. Under Delaware law, directors serving on a classified board may not be removed by shareholders except for cause. Also, pursuant to the terms of our shareholder rights plan, each outstanding share of common stock has one attached right. The rights will cause substantial dilution of the ownership of a person or group that attempts to acquire us on terms not approved by the Board of Directors and may have the effect of deterring hostile takeover attempts. The effect of these anti-takeover provisions may deter business combination transactions not approved by our Board of Directors, including acquisitions that may offer a premium over the market price to some or all stockholders.

The price of our common stock has been volatile and could continue to fluctuate in the future.

The market price of our common stock, like that of many other high-technology companies, has fluctuated significantly and is likely to continue to fluctuate in the future. During fiscal year 2016, the closing price of our common stock on the NASDAQ Global Select Market ranged from $7.88 to $13.00 per share. Our closing sale price on December 9, 2016 was $13.65per share. Following the announcement of an unsolicited takeover proposal on November 8, 2016, the price of our common stock increased significantly. If this proposal were to be withdrawn, the price of our common stock may move significantly. Further, announcements by us or others regarding the receipt of customer orders, quarterly variations in operating results, departures of key personnel, acquisitions or divestitures, additional equity or debt financings, results of customer field trials, scientific

discoveries, technological innovations, litigation, product developments, patent or proprietary rights, government regulation and general market conditions and risks may, for example, have a significant impact on the market price of our common stock.

If our stock price declines over a sustained period of time or our profits significantly decrease, we may need to recognize an impairment of our goodwill.

The price of our common stock could decline. If such a decline continued over a sustained period of time, we could have an impairment of our goodwill. Our market value is dependent upon certain factors, including continued future growth of our products and solutions. If such growth does not materialize or our forecasts are not met, our profits could be significantly reduced and our market value may decline, which could result in an impairment of our goodwill. 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.

In addition to the above locations, we perform sales activities in various other locations in Europe and Canada that are not deemed to be principal locations and are not listed above. In connection with our sale of the Etherios business in October 2015, we no longer maintain operations in Chicago, IL, Dallas, TX or San Francisco, CA.

We have consolidated and relocated office locations due to a fiscal 2016 restructuring (see Note 10 to our Consolidated Financial Statements). We moved our Wireless Design Services team from an office in downtown Minneapolis to our World Headquarters in suburban Minnetonka. Additionally, we closed our office location in Dortmund, Germany and moved the corresponding positions to our existing office in Ismaning just outside of Munich, Germany.

ITEM 3. LEGAL PROCEEDINGS

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. While we are unable to predict the outcome of any potential claims or litigation due to the inherent unpredictability of these matters, we believe that it is possible that we could, in the future, incur judgments or enter into settlements of claims that could have a material adverse effect on our operations in any particular period.

ITEM 4. MINE SAFETY DISCLOSURES

Dividend Policy

We have never paid cash dividends on our common stock. Our Board of Directors presently intends to retain all earnings for use in our business, except for periodic stock repurchases, and does not anticipate paying cash dividends in the foreseeable future.

Issuer Repurchases of Equity Securities

On April 26, 2016, our Board of Directors authorized a program to repurchase up to $15.0 million of our common stock primarily to return capital to shareholders. This authorization expires on May 1, 2017. Shares repurchased under this program may be made through open market and privately negotiated transactions from time to time and in amounts that management deems appropriate. The amount and timing of share repurchases, if any, depends upon market conditions and other corporate considerations. As of the date of this filing, no shares were repurchased under this program.

The following table presents the information with respect to purchases made by or on behalf of Digi International Inc. or any “affiliated purchaser” (as defined in Rule 10b-18(a)(3) under the Securities Exchange Act of 1934), of our common stock during the fourth quarter of fiscal 2016:

Performance Evaluation

The graph below compares the total cumulative stockholders’ return on our Common Stock for the period from the close of the NASDAQ Stock Market - U.S. Companies on September 30, 2011 to September 30, 2016, the last day of fiscal 2016, with the total cumulative return for the NASDAQ U.S. Benchmark TR Index (the U.S. Benchmark Index) and the NASDAQ Telecommunications Index (the Peer Index) over the same period. We have determined that our line of business is mostly comparable to those companies in the Peer Index. The index level for the graph and table was set to $100 on September 30, 2011, for our Common Stock, the U.S. Benchmark Index and the Peer Index and assumes the reinvestment of all dividends.

ITEM 7. 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 consolidated financial statements and other information in this Annual Report on Form 10-K for the fiscal year ended September 30, 2016.

FORWARD-LOOKING STATEMENTS

This Annual Report 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.

Words such as “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 the company operates, 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 demand for and 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 ability to integrate our products and services with those of other parties in a commercially accepted manner, 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 could negatively impact our supply chain and customers, potential unintended consequences associated with restructuring or other similar business initiatives that may impact our ability to retain important employees, the ability to achieve the anticipated benefits and synergies associated with acquisitions or divestitures, 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, those described in Item 1A, Risk Factors, of this Form 10-K and subsequent quarterly reports of Form 10-Q and other filings, could cause our 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.

PRESENTATION OF NON-GAAP FINANCIAL MEASURES

This report includes Adjusted EBITDA from continuing operations, which is a non-GAAP financial measure. Non-GAAP financial measures are not substitutes for GAAP financial measures, such as net income, for the purpose of analyzing financial performance. The disclosure of these measures does not reflect all charges and gains that were actually recognized by the company. Non-GAAP financial measures are not prepared in accordance with, or an alternative for measures prepared in accordance with, generally accepted accounting principles and may be different from non-GAAP financial measures used by other companies. In addition, non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles. Non-GAAP financial measures have limitations in that they do not reflect all of the amounts associated with our results of operations as determined in accordance with GAAP and that these measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP financial measures. Additionally, we understand that Adjusted EBITDA from continuing operations does not reflect our cash expenditures, the cash requirements for the replacement of depreciated and amortized assets, or changes in or cash requirements for our working capital needs.

We believe that the presentation of Adjusted EBITDA from continuing operations as a percentage of revenue is useful because it provides a reliable and consistent approach to measuring our performance from year to year and in assessing our performance against that of other companies. We believe this information helps compare operating results and corporate performance exclusive of the impact of our capital structure and the method by which assets were acquired. EBITDA from continuing operations is used as an internal metric for executive compensation, as well as incentive compensation for the rest of the employee base, and it is monitored quarterly for these purposes.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

OVERVIEW

We have a single operating and reporting segment. Our revenue consists of hardware product revenue and service revenue. Our hardware product offerings are comprised of our cellular routers and gateways, radio frequency (“RF”), embedded and network products. Our service offerings include Digi Cold Chain Solutions (formed in October 2015 through our acquisition of Bluenica Corporation), wireless design services, Digi Device Cloud (which includes Digi Remote Manager™) and support services.

In October 2015, we sold Etherios as part of a strategy to focus on providing highly reliable machine connectivity solutions for business and mission-critical application environments (see Note 3 to the Consolidated Financial Statements). As a result of the disposition, we have accounted for the Etherios business as a discontinued operation. On November 1, 2016 we completed the acquisition of FreshTemp, LLC to enhance and expand the capabilities and scale of Digi Cold Chain Solutions (see Note 19 to our Consolidated Financial Statements).

We utilize many financial, operational, and other metrics to evaluate our financial condition and financial performance. Below we highlight the fiscal 2016 metrics that we feel are most important in these evaluations:

• Revenue was $203.0 Million. Our revenue decreased by $0.8 million, or 0.4%, compared to fiscal 2015. This decrease was due to a decrease in service revenue of $1.4 million, offset by an increase in product revenue of $0.6 million.

• Gross Margin was 49.1%.  Our gross margin increased as a percentage of revenue to 49.1% in fiscal 2016 from 47.6% in fiscal 2015. Hardware product gross margin was 49.9% in fiscal 2016, compared to 48.3% in the prior fiscal year. Service gross margin for fiscal 2016 was 26.7% compared to 33.3% in the prior fiscal year.

• Income from Continuing Operations was $13.5 Million and Earnings Per Diluted Share from Continuing Operations were $0.51. Our income from continuing operations increased by $4.0 million, or 42.9%, compared to fiscal 2015. Earnings per diluted share from continuing operations were $0.51 in fiscal 2016, compared to $0.37 in fiscal 2015. Our improved gross margin and our focus on managing our operating expenses allowed us to improve our income from continuing operations in fiscal 2016.

• Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization adjusted for gain from insurance recovery (Adjusted EBITDA) from Continuing Operations was $21.0 Million. Our Adjusted EBITDA from continuing operations was $21.0 million, or 10.4% of revenue, in fiscal 2016, compared to $16.9 million, or 8.3% of revenue, in fiscal 2015. Below is a table reconciling income from continuing operations to Adjusted EBITDA from continuing operations (in thousands):

	Year ended September 30,
	2016					2015
				% of total revenue					% of total revenue
Total revenue	$	203,005		100.0	%	$	203,847		100.0	%
Income from continuing operations	$	13,478		6.6	%	$	9,433		4.6	%
Gain from insurance recovery	—			—		(1,375		)	(0.6	)
Interest income, net	(254		)	(0.1	)	(214		)	(0.1	)
Income tax provision	3,212			1.6		3,684			1.8
Depreciation and amortization	4,584			2.3		5,347			2.6
Adjusted earnings from continuing operations before interest, taxes, depreciation and amortization adjusted for gain from insurance recovery	$	21,020		10.4	%	$	16,875		8.3	%

• Our Balance Sheet was Positively Impacted by Investing and Financing Decisions.  Our current ratio was 8.2 to 1 at September 30, 2016, compared to 6.9 to 1 at September 30, 2015.  Cash and cash equivalents and marketable securities, including long-term marketable securities, increased $31.9 million to $137.7 million at September 30, 2016.

We accomplished a number of key initiatives in fiscal 2016 and also faced significant challenges relative to our business.

23

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

Accomplishments

• Our total cash and cash equivalents and marketable securities including long-term marketable securities, amounted to $137.7 million at September 30, 2016, an increase of $31.9 million from September 30, 2015.

• In October 2015, we sold our Etherios CRM consulting business. While we initially acquired Etherios in large part because we believed it would help drive engagements with companies looking to deploy IoT solutions within their businesses, we were not rewarded in the marketplace as we had hoped. In turn, we were operating a business that was not fully tied to our core expertise. The divestiture brought more focus to our core business.

• During fiscal 2016, we have continued to reduce the number of product stock keeping units (SKUs) we produce, which we believe will have significant implications on our ability to manage inventory effectively, improve channel stocking strategies and control costs.

• We simplified and scaled our business. We reduced the number of office locations by consolidating our Wireless Design Services team into our World Headquarters and closed our Dortmund, Germany office and relocated to our Munich, Germany office.

• In October 2015, we acquired Bluenica Corporation, which formed the basis for Digi Cold Chain Solutions. This company is focused on temperature monitoring of perishable goods in the food industry by using wireless sensors and is monitored through our gateway to our application. The acquisition leverages our existing strength as a provider of IoT hardware and related software while providing us with a recurring revenue stream.

• We achieved adjusted EBITDA from continuing operations of 10.4% for fiscal 2016.

• Our network products posted better than expected results increasing by 11.5% in fiscal 2016 compared to fiscal 2015. Generally, however, demand for these products has been declining for several years and we expect revenues for these products will continue to decline in the future.

Challenges

• Our cellular products and gateways experienced a revenue decline of 17.5% in fiscal 2016 as compared to fiscal 2015. The decline is primarily due to the loss of large strategic accounts and a delay in certain product introductions.

• Our service revenue declined 17.3% during fiscal 2016 vs. fiscal 2015, primarily due to our wireless design services as we struggled to generate sufficient demand while we transitioned this business both from a physical location and senior leadership perspective. Historically, revenue from our wireless design services has fluctuated from quarter to quarter and we expect that trend to continue.

• In June 2016, the United Kingdom’s (U.K.) held a referendum in which voters approved an exit from the European Union (E.U.) widely referred to as “Brexit.” The announcement of Brexit caused significant volatility in global stock markets and currency exchange rate fluctuations that resulted in the strengthening of the U.S. dollar against the British pound. Brexit could cause disruptions to and create uncertainty surrounding our business, including continued increased volatility in exchange rates, as the future terms of the U.K.’s relationship with the E.U. are determined.

Total revenue was $203.0 million in fiscal 2016 compared to $203.8 million in fiscal 2015, a decrease of $0.8 million or 0.4%. Service revenue decreased $1.4 million, or 17.3%, partially offset by an increase in product revenue of $0.6 million, or 0.3%. Total revenue was $203.8 million in fiscal 2015 compared to $183.2 million in fiscal 2014, an increase of $20.6 million or 11.3%. Product revenue increased by $22.7 million, or 13.1%, partially offset by a decrease in service revenue of $2.0 million, or 19.1%. We did not experience a material change in revenue due to pricing during fiscal 2016, 2015 or 2014.

Foreign currency rates compared to the prior year's rates had an unfavorable impact on revenue of $1.1 million and $3.4 million for fiscal 2016 and 2015, respectively, and a favorable impact on revenue of $0.8 million in fiscal 2014.

The following summarizes our product revenue by product categories:

	Product Revenue						% of Product Revenue
($ in millions)	2016		2015		2014		2016		2015		2014
Cellular routers and gateways	$	48.4	$	58.7	$	39.2	24.7	%	30.0	%	22.7	%

Network	57.3		51.4		54.9		29.2	%	26.3	%	31.8	%
Total product revenue	$	196.1	$	195.5	$	172.8	100.0	%	100.0	%	100.0	%

2016 Compared to 2015

Cellular routers and gateways product revenue decreased $10.3 million, or 17.5%, in fiscal 2016 as compared to fiscal 2015. This decrease primarily was due to lower purchases by significant customers, across all regions. In addition, there were delays of certain product introductions. Cellular router and gateway revenue is substantially driven by large awards-based customer projects and is subject to revenue fluctuations from quarter to quarter, based on when the awarded projects are deployed.

RF product revenue decreased $0.5 million in fiscal 2016 as compared to the prior fiscal year due to slower sales to energy-related customers.

Embedded product revenue increased $5.5 million, or 10.6%, in fiscal 2016 as compared to fiscal 2015 as significant customers have begun moving new initiatives to production in the North America and EMEA regions.

Network product revenue increased $5.9 million, or 11.5%, in fiscal 2016 as compared to fiscal 2015 primarily related to large terminal server sales to significant customers. Most of our network products are in the mature phase of their product life cycle. We expect that revenue from these products will generally decrease in the future.

2015 Compared to 2014

Cellular routers and gateway product revenue increased $19.5 million, or 49.6%, in fiscal 2015 as compared to fiscal 2014. These increases primarily were due to a growing market performance and expanding market share with large sales to certain customers of our cellular routers and gateway products. We believe sales of these products in fiscal 2015 significantly outpaced the industry growth rate.

RF product revenue increased $5.3 million, or 18.1%, in fiscal 2015 as compared to fiscal 2014 primarily due to larger sales to certain customers of modules and wireless communication adapters. All of our RF products are included in the growth product category.

Embedded product revenue increased by $1.4 million, or 2.8%, in fiscal 2015 as compared to fiscal 2014 primarily related to our embedded modules and chips, partially offset by a decrease in the sales of Rabbit® modules, which are in the mature portion of their product life cycle.

Network product revenue decreased $3.5 million, or 6.3%, in fiscal 2015 as compared to fiscal 2014. The decrease was mostly due to a decrease in sales of serial cards which are in the mature portion of their product life cycle. There was also a decrease in USB connected products, device servers and satellite products (which have been discontinued), partially offset by an increase in revenue from terminal servers. All of our network products are included in the mature product category.

Service

2016 Compared to 2015

Service revenue for fiscal 2016 was $6.9 million compared to $8.3 in the prior fiscal year, a decrease of $1.4 million, or 17.3%. The decrease was primarily due to a $1.5 million decline in revenue for our wireless design services as we struggled to generate sufficient demand while we were transitioning this business to our World Headquarters location as well as identifying new senior leadership. Revenue from the Digi Device Cloud™ platform and support services decreased by $0.6 million. We received incremental revenue from Digi Cold Chain Solutions of $0.7 million which was acquired during the first quarter of

26

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

fiscal 2016. We expect that revenue from Digi Cold Chain Solutions will continue to increase as we focus on expanding this business, which includes a component of recurring revenue.

2015 Compared to 2014

Our service offerings in fiscal 2015 included wireless design services, revenue generated from the Digi Device Cloud™ platform and our support services. The significant majority of our service revenue was generated from wireless design services.

Service revenue for fiscal 2015 was $8.3 million compared to $10.3 million in the prior fiscal year, a decrease of $2.0 million, or 19.1%. The decrease was primarily due to a decline in revenue from our wireless design services.

Revenue by Geographic Location

Our revenue by geographic location of our customers was as follows:

	Revenue						% of Revenue
($ in millions)	2016		2015		2014		2016		2015		2014
North America, primarily United States	$	131.5	$	127.6	$	106.9	64.8	%	62.6	%	58.4	%
Europe, Middle East & Africa	44.9		47.5		47.7		22.1	%	23.3	%	26.0	%
Asia	20.4		22.9		22.8		10.0	%	11.2	%	12.4	%
Latin America	6.2		5.8		5.8		3.1	%	2.9	%	3.2	%
Total revenue	$	203.0	$	203.8	$	183.2	100.0	%	100.0	%	100.0	%

2016 Compared to 2015

North America revenue in fiscal 2016 increased $3.9 million, or 3.0%, compared to fiscal 2015. This was primarily due to a $5.3 million increase in product revenue mostly related to higher sales of network and embedded products. This was partially offset by a decrease in cellular gateway products and a decrease in service revenue mostly related to wireless design services.

EMEA revenue decreased $2.6 million, or 5.5%, in fiscal 2016 from fiscal 2015. The British Pound and Euro weakened compared to the U.S. Dollar during fiscal 2016, which contributed to the decrease in revenue. In addition revenue decreased for cellular-related and RF products, partially offset by an increase in revenue from embedded products compared to the same periods in the prior year.

Revenue in Asian countries decreased by $2.5 million, or 11.0%, in fiscal 2016 compared to fiscal 2015 mostly related to decreased volume of network products.

Latin America revenue increased by $0.4 million, or 6.9%, in fiscal 2016 from fiscal 2015, primarily due to increased RF product sales in fiscal 2016.

2015 Compared to 2014

North America revenue in fiscal 2015 increased $20.7 million, or 19.4%, compared to fiscal 2014, as certain customers made large purchases of our cellular products. There was also an increase in revenue from our RF and embedded modules and serial servers, partially offset by a decline of $2.0 million in service revenue.

EMEA revenue decreased $0.2 million, or 0.4%, in fiscal 2015 as compared to fiscal 2014. The decrease primarily was due to fluctuations of foreign currency rates, which had an unfavorable impact on total revenue of $3.2 million for fiscal 2015 as compared to fiscal 2014 due to the weakening of the Euro and British Pound compared to the U.S. Dollar. This was mostly offset by increased revenue from cellular products and embedded products compared to the prior fiscal year.

Asian countries revenue increased $0.1 million, or 0.6%, in fiscal 2015 as compared to fiscal 2014.

Latin America revenue remained flat in fiscal 2015 as compared to fiscal 2014.

Revenue by Distribution Channel

The following table presents our revenue by distribution channel:

	Revenue						% of Revenue
($ in millions)	2016		2015		2014		2016		2015		2014
Direct/OEM channel	$	68.8	$	77.9	$	67.7	33.9	%	38.2	%	37.0	%
Distributors channel	134.2		125.9		115.5		66.1	%	61.8	%	63.0	%
Total revenue	$	203.0	$	203.8	$	183.2	100.0	%	100.0	%	100.0	%

2016 Compared to 2015

Revenue in fiscal 2016 in our Direct/OEM channel decreased by $9.1 million, or 11.7%, compared to the prior fiscal year primarily resulting from lower sales of cellular and RF products and from our service offerings. During fiscal 2016, revenue from our distributors increased by $8.3 million, or 6.6%, compared to fiscal 2015, as we continued to advance our efforts to expand our relationships with certain distributors that have global scale in fiscal 2016.

2015 Compared to 2014

During fiscal 2015, revenue in our Direct/OEM channel increased $10.2 million, or 15.1%, compared to revenue in fiscal 2014 due to large sales to certain customers. Revenue in fiscal 2015 for our distributors increased by $10.4 million, or 9.0%, compared to revenue in fiscal 2014. We have been taking steps to expand our relationship with certain distributors who have a global reach.

GROSS PROFIT

2016 Compared to 2015

Gross profit was $99.7 million and $97.1 million in fiscal 2016 and 2015, respectively, an increase of $2.6 million, or 2.6%. The gross margin for fiscal 2016 was 49.1% compared to 47.6% in fiscal 2015.

Hardware product gross profit was $97.8 million and $94.3 million in fiscal 2016 and 2015, respectively, an increase of $3.5 million, or 3.7%. The hardware product gross margin for fiscal 2016 was 49.9% compared to 48.3% in fiscal 2015. The increase was driven primarily by strong revenue performance in our network category which traditionally has higher margin products. In addition, we realized manufacturing cost reductions across many of our product lines in fiscal 2016.

Service gross profit was $1.8 million and $2.8 million in fiscal 2016 and 2015, respectively, a decrease of $0.9 million, or 33.6%. The service gross margin for fiscal 2016 was 26.7% compared to 33.3% in fiscal 2015. This primarily was a result of amortization costs for purchased and core technology associated with our Cold Chain Solutions acquisition in the first quarter of fiscal 2016 and lower revenue from wireless design services. We expect our service gross margin to vary from quarter to quarter for the foreseeable future as our wireless product design and development services margins are dependent on the utilization rates of our personnel.

2015 Compared to 2014

Gross profit was $97.1 million and $90.4 million in fiscal 2015 and 2014, respectively, an increase of $6.7 million, or 7.5%. The gross margin for fiscal 2015 was 47.6% compared to 49.3% in fiscal 2014.

Hardware product gross profit was $94.3 million and $87.1 million in fiscal 2015 and 2014, respectively, an increase of $7.2 million, or 8.3%. The hardware product gross margin for fiscal 2015 was 48.3% compared to 50.4% in fiscal 2014. The decrease in gross margin primarily was due to the mix of our hardware products since we sold proportionately more growth hardware products in fiscal 2015 that generally have a lower gross margin compared to mature hardware products. In the future we expect to focus more on securing larger and longer-term opportunities that may impact our gross margins negatively. Additionally, for fiscal 2015, we incurred additional manufacturing expenses to recover from the impact of the Thailand fire that also reduced gross margin.

28

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

Service gross profit was $2.8 million and $3.3 million in fiscal 2015 and 2014, respectively, a decrease of $0.5 million, or 15.0%. The service gross margin for fiscal 2015 was 33.3% compared to 31.6% in fiscal 2014. The increase in gross margin is a direct result of improved utilization of consulting labor in connection with our restructuring (see Note 10 to our Consolidated Financial Statements).

OPERATING EXPENSES

2016 Compared to 2015

Operating expenses were $82.6 million in fiscal 2016, a decrease of $3.6 million, or 4.2%, compared to $86.2 million in fiscal 2015. Below is a summary of our operating expenses by function:

Sales and marketing expenses were $33.8 million and $37.6 million in fiscal 2016 and 2015, respectively, a decrease of $3.8 million or 9.9%. This decrease was due primarily to decreased compensation and employee-related expenses of $3.0 million as a result of reduced headcount. Travel and entertainment expenses also decreased by $0.3 million.

Research and development expenses were $30.9 million and $29.9 million in fiscal 2016 and 2015, respectively, an increase of $1.0 million or 3.4%. Compensation and employee-related expenses increased by $1.5 million as a result of underutilization of billable research and development resources as well as increased contract labor costs. Outside services for testing and certifications increased by $0.3 million. This was partially offset by decreases of $0.8 million in travel and entertainment, occupancy and other miscellaneous research and development costs.

General and administrative expenses were $17.0 million and $18.3 million in fiscal 2016 and 2015, respectively, a decrease of $1.3 million or 7.0%. The decrease is primarily related to compensation-related expenses of $0.7 million, as fiscal 2015 included Chief Financial Officer transition expenses. In addition there was a decrease in expenses of $0.7 million as we reduced the fair value of the contingent consideration associated with our acquisition of Bluenica (see Note 2 to our Consolidated Financial Statements).

Restructuring expenses were $0.7 million in fiscal 2016 and $0.4 million in fiscal 2015. For further information on restructurings, see Note 10 to our Consolidated Financial Statements.

2015 Compared to 2014

Operating expenses were $86.2 million in fiscal 2015, an increase of $0.2 million, or 0.3%, compared to $86.0 million in fiscal 2014. Below is a summary of our operating expenses by function:

Sales and marketing expenses were $37.6 million and $38.8 million in fiscal 2015 and 2014, respectively, a decrease of $1.2 million or 3.0%. The decrease was primarily due to a reduction in travel expenses of $0.6 million and $1.0 million of facility, outside services and other sales and marketing expenses. This was partially offset by an increase in compensation-related expenses of $0.4 million.

Research and development expenses were $29.9 million and $28.9 million in fiscal 2015 and 2014, respectively, an increase of $1.0 million or 3.6%. Compensation and employee-related expenses increased by $2.0 million primarily due to underutilization of billable research and development and using those employees for completing internal products. In addition, incentive compensation expenses increased due to improved company performance in fiscal 2015. This was partially offset by a decrease of $1.0 million in other miscellaneous research and development costs and professional services.

General and administrative expenses were $18.3 million and $18.2 million in fiscal 2015 and 2014, respectively, an increase of $0.1 million or 0.3%. This was primarily due to an increase in professional fees of $0.5 million and compensation and employee-related expenses of $1.3 million mostly related to increased incentive compensation expenses due to improved company performance in fiscal 2015. In addition, we realized a net decrease of $0.7 million in expenses due to CEO transition expenses incurred in fiscal 2014 which were only partially offset by CFO transition expenses in fiscal 2015. General and administrative expenses also decreased $1.0 million in fiscal 2015 compared to the prior fiscal year due to occupancy expenses, miscellaneous general and administrative expenses, depreciation and amortization as certain intangibles were fully amortized.

Restructuring expenses were $0.4 million and $0.1 million in fiscal 2015 and fiscal 2014, respectively, an increase of $0.3 million. For further information on restructuring, see Note 10 to our Consolidated Financial Statements.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

OTHER (EXPENSE) INCOME, NET

2016 Compared to 2015

Total other (expense) income, net was comprised of other expense, net of $0.4 million in fiscal 2016 compared to other income, net of $2.2 million in fiscal 2015. In fiscal 2016, we recorded $0.7 million of foreign currency net transaction losses compared to fiscal 2015 in which we recorded $0.6 million of foreign currency net transaction gains and a $1.4 million of gain from the settlement of a property and casualty insurance claim related to the replacement of our capital equipment destroyed in the fire at our subcontract manufacturer's location. Our interest income on marketable securities and cash and cash equivalents increased from fiscal 2015 to fiscal 2016 as our average investment balance increased from $74.0 million in fiscal 2015 to $102.3 million in fiscal 2016. We earned an average interest rate of 0.4% and 0.3% in fiscal 2016 and 2015, respectively.

2015 Compared to 2014

We recorded other income, net of $2.2 million in fiscal 2015 compared to $0.7 million in fiscal 2014. In fiscal 2015, we recorded $1.4 million of gain from the settlement of a property and casualty insurance claim related to the replacement of our capital equipment destroyed in the fire at our subcontract manufacturer's location. We also recorded $0.6 million of foreign currency net transaction gains in fiscal 2015 as compared to $0.4 million of foreign currency net transaction gains in fiscal 2014. Our interest income remained mostly the same. Our average investment balance was $74.0 million in fiscal 2015 and $74.1 million in fiscal 2014. We earned an average interest rate of 0.3% in both fiscal 2015 and fiscal 2014.

INCOME TAXES

Our effective income tax rates were 19.2%, 28.1% and 11.2% for fiscal years 2016, 2015 and 2014, 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 (see Note 11 to our Consolidated Financial Statements).

During fiscal 2016, we recorded net tax benefits of $1.5 million, primarily from the reinstatement of the federal research and development tax credit for calendar year 2015 and the reversal of tax reserves due to the expiration of statutes of limitation from U.S. and foreign tax jurisdictions. In addition, we filed amended income tax returns resulting in an additional domestic refund related to qualified manufacturing activities.

During fiscal 2015, we recorded net tax benefits of $0.8 million, resulting from the reinstatement of the research and development tax credit for calendar year 2014, reversal of tax reserves due to the expiration of statute of limitations from U.S. and foreign tax jurisdictions and reversal of tax reserves due to the resolution of tax audits.

During fiscal 2014, we recorded net tax benefits of $1.5 million related to the re-measurement and reversal of certain income tax reserves as a result of a federal income tax audit of fiscal 2012, the reassessment of state research and development tax credits and the release of income tax reserves due to the expiration of statute of limitations from U.S. and foreign tax jurisdictions.

INFLATION

Management believes that during fiscal years 2016, 2015 and 2014, inflation has not had a material effect on our consolidated statement of operations or financial position.

LIQUIDITY AND CAPITAL RESOURCES

We have financed our operations principally with funds generated from operations. We held cash, cash equivalents and short-term marketable securities of $134.1 million, $92.2 million and $80.4 million at September 30, 2016, 2015 and 2014, respectively. Our working capital was $171.8 million, $137.0 million and $125.9 million at September 30, 2016, 2015 and 2014, respectively. The increase of cash, cash equivalents and short-term marketable securities and working capital during fiscal 2016 was attributable primarily to increased net income and less investment in non-current marketable securities than in fiscal 2015. As a result of adopting ASU 2015-17 prospectively in the first quarter of fiscal 2016, all deferred tax assets and liabilities are classified on a jurisdictional basis as non-current in our condensed consolidated balance sheets, which is a change from our historical presentation whereby certain of our deferred tax assets and liabilities were classified as current and the remainder was classified as non-current.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

In November 2016, we spent $1.7 million on the acquisition of FreshTemp, LLC (see Note 19 to the Consolidated Financial Statements).

Consolidated Statements of Cash Flows Highlights:

	Year ended September 30,
($ in thousands)	2016			2015			2014
Operating activities	$	27,089		$	14,074		$	1,809

Net increase (decrease) in cash and cash equivalents	$	30,709		$	(2,472	)	$	6,170

2016 Compared to 2015

Net cash provided by operating activities was $27.1 million during fiscal 2016 compared to $14.1 million during fiscal 2015, a net increase of $13.0 million. This net increase is due to an increase of $8.4 million in net income adjusted for non-cash items and a net increase in cash flows resulting from operating assets and liabilities of $4.6 million. The increase in cash flows related to changes in operating assets and liabilities was primarily due to an increase $5.9 million resulting from a reduction in inventory, an increase in accounts payable of $5.4 million, and an increase of $1.0 million resulting from a reduction of accounts receivable, prepaids and other assets. This was partially offset by a reduction of accrued liabilities of $5.7 million and a reduction of $2.0 million of taxes payable.

Net cash used by investing activities was $3.8 million in fiscal 2016 compared to $19.5 million in fiscal 2015, a net decrease of $15.7 million. We purchased $15.3 million fewer marketable securities in fiscal 2016 as compared to fiscal 2015. We received $2.8 million in proceeds from the sale of Etherios, net of cash acquired, in fiscal 2016 and spent $1.8 million less for capital expenditures in fiscal 2016 compared to fiscal 2015. This was partially offset by cash used for the acquisition of Bluenica of $2.9 million and proceeds from an insurance settlement in fiscal 2015 of $1.4 million.

Net cash provided by financing activities was $7.7 million in fiscal 2016 compared to $5.1 million in fiscal 2015, an increase of $2.6 million. We repurchased $1.8 million less of our common stock in fiscal 2016 compared to fiscal 2015, and received $0.8 million of additional proceeds related to exercises of stock options and employee stock purchase plan transactions.

2015 Compared to 2014

Net cash provided by operating activities was $14.1 million during fiscal 2015 compared to $1.8 million in fiscal 2014, a net increase of $12.3 million. This net increase was primarily due to an increase of $7.6 million of net income adjusted for non-cash items and a net increase in cash flows resulting from changes in operating assets and liabilities of $4.6 million. The net increase in cash flows resulting from changes in operating assets and liabilities of $4.6 million was primarily due to a $4.8 million increase in accrued liabilities resulting from larger incentive compensation accruals on improved company performance in fiscal 2015. We also had an increase in cash flows as we spent $4.0 million less on inventory in fiscal 2015 compared to fiscal 2014. In addition, we had a $0.9 million increase in cash flows as our accounts receivable increased by a smaller amount in fiscal 2015 compared to fiscal 2014. This was partially offset by a $4.7 million decrease in cash flows related to accounts payable and a $0.4 million decrease related to income taxes payable.

Net cash used in investing activities was $19.5 million in fiscal 2015 compared to net cash provided of $16.6 million in fiscal 2014, a decrease of $36.1 million. There were net purchases of marketable securities in fiscal 2015 compared to net maturities of marketable securities in fiscal 2014 which accounted for $36.4 million of the decrease along with $1.1 million of additional purchases of capital expenditures. This was partially offset by an increase of $1.4 million related to the gain from insurance recovery.

Net cash provided by financing activities was $5.1 million in fiscal 2015 compared to net cash used by financing activities of $11.0 million in fiscal 2014. We had $13.4 million fewer repurchases of common stock in fiscal 2015 compared to fiscal 2014. We also had $2.7 million of additional proceeds from exercises of stock options and employee stock purchase plan transactions in fiscal 2015 compared to fiscal 2014.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

We expect positive cash flows from operations and 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 and capital expenditures for the next twelve months and beyond.

At September 30, 2016, our total cash and cash equivalents and marketable securities balance, including long-term marketable securities was $137.7 million. Approximately $28.4 million of cash and cash equivalents was being held by our controlled foreign subsidiaries at September 30, 2016. At September 30, 2016, we had $31.5 million of accumulated undistributed foreign earnings that are indefinitely reinvested in non-U.S. subsidiaries, resulting in slightly more than half of our cash and cash equivalents being held by non-U.S. subsidiaries. Although we have no current need or intention to repatriate historical earnings in the form of cash in the United States, if we change our assertion from indefinitely reinvesting undistributed foreign earnings, 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 up to $0.6 million.

The following summarizes our contractual obligations at September 30, 2016:

	Payments due by fiscal period
($ in thousands)	Total		Less than 1 year		1-3 years		3-5 years		Thereafter
Operating leases	$	3,922	$	1,706	$	1,758	$	458	$	—

The operating lease agreements included above primarily relate to office space. The table above does not include possible payments for uncertain tax positions. Our reserve for uncertain tax positions, including accrued interest and penalties, was $1.9 million as of September 30, 2016. Due to the nature of the underlying liabilities and the extended time often needed to resolve income tax uncertainties, we cannot make reliable estimates of the amount or timing of future cash payments that may be required to settle these liabilities.

The above table also does not include those obligations for royalties under license agreements as these royalties are calculated based on future sales of licensed products and we cannot make reliable estimates of the amount of cash payments.

FOREIGN CURRENCY

We are exposed to foreign currency transaction risk associated with certain sales being denominated in Euros, British Pounds, Japanese Yen and Canadian Dollar 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 manage our net asset or net liability position for U.S. dollar accounts in our foreign locations to reduce our foreign currency risk. We have not implemented a formal hedging strategy to reduce foreign currency risk.

During 2016, we had approximately $71.5 million of revenue related to foreign customers including export sales, of which $22.9 million was denominated in foreign currency, predominantly the Euro and British Pound. During fiscal 2015 and 2014, we had approximately $76.2 million and $76.3 million, respectively of revenue to foreign customers including export sales, of which $21.3 million and $23.3 million, respectively, were denominated in foreign currency, predominantly the Euro and British Pound. In future periods, we expect a significant portion of sales will continue to be made in Euros and British Pounds.

In June 2016, the U.K. held a referendum in which voters approved Brexit. The announcement of Brexit caused significant volatility in global stock markets and currency exchange rate fluctuations that resulted in the strengthening of the U.S. dollar against the British pound. Brexit could cause disruptions to and create uncertainty surrounding our business, including continued increased volatility in exchange rates, as the future terms of the U.K.’s relationship with the E.U. are determined.

RECENT ACCOUNTING DEVELOPMENTS

For information on new accounting pronouncement, see Note 1 to our Consolidated Financial Statements.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect

32

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

the reported amounts of assets, liabilities, revenue and expenses, the disclosure of contingent assets and liabilities and the values of purchased assets and assumed liabilities in acquisitions. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

We believe the following critical accounting policies impact our more significant judgments and estimates used in the preparation of our consolidated financial statements.

REVENUE RECOGNITION

Our revenue is derived primarily from the sale of wired and wireless hardware products to our distributors and Direct/OEM customers. We recognize hardware 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. 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 and distribution sales for the current period. Estimated reserves for future returns and price adjustments are charged against revenue in the same period as the corresponding sales are recorded. Material differences between the historical trends used to determine estimated reserves and actual returns and pricing adjustments could result in a material change to our consolidated results of operations or financial position. We have applied consistent methodologies for estimating reserves for future returns and pricing adjustments for all years presented. The reserve for future returns and pricing adjustments was $2.0 million at September 30, 2016 and $1.8 million at September 30, 2015.

Revenue recognized for service revenue as a percentage of total revenue represented 3.4%, 4.1% and 5.6% in fiscal 2016, 2015 and 2014, respectively. Our service revenue is derived primarily from our wireless design services and our Digi Cold Chain Solutions. We also have some service revenue that is derived from our Digi Device Cloud™, which is a platform-as-a-service (PaaS) offering in which customers pay for services consumed in terms of devices being managed and monitored, or as a monthly service fee for access to information.  In addition, we have small amounts of revenue from our support services. We recognize service revenue from our wireless design services, Digi Cold Chain Solutions and Device Cloud based upon performance, including final product delivery and customer acceptance.  In addition, we recognize small amounts of revenue from support services which is recognized over the life of the contract, and training as the services are performed.

MARKETABLE SECURITIES

We regularly monitor and evaluate the realizable 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 these securities has occurred and is other-than-temporary, we would record a charge to other (expense) income.

ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS

We maintain an allowance for doubtful accounts, which reflects the estimate of losses that may result from the inability of some of our customers to make required payments. The estimate for the allowance for doubtful accounts is based on known circumstances regarding collectability of customer accounts and historical collections experience. If the financial condition of one or more of our customers were to deteriorate, resulting in an inability to make payments, additional allowances may be required. Material differences between the historical trends used to estimate the allowance for doubtful accounts and actual collection experience could result in a material change to our consolidated results of operations or financial position. The allowance for doubtful accounts was $0.2 million at September 30, 2016 and $0.3 million at September 30, 2015.

33

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

INVENTORIES

Inventories are stated at the lower of cost or fair market value, with cost determined using the first-in, first-out method. We reduce the carrying value of our inventories for estimated excess and obsolete inventories equal to the difference between the cost of inventory and its estimated realizable value based upon assumptions about future product demand and market conditions. Once the new cost basis is established, the value is not increased with any changes in circumstances that would indicate an increase in value after the remeasurement. If actual product demand or market conditions are less favorable than those projected by management, additional inventory write-downs may be required that could result in a material change to our consolidated results of operations or financial position. We have applied consistent methodologies for the net realizable value of inventories.

GOODWILL

Goodwill represents the excess of cost over the fair value of identifiable assets acquired.  In a business combination, goodwill is capitalized at the acquisition date. It is measured at fair value, which is the excess of the acquisition price for shares in a company over the acquired net assets. The net assets include the fair values of the acquired identifiable assets less the assumed liabilities and contingent liabilities.

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, 2016, our market capitalization was $278.6 million compared to our carrying value of $294.9 million. Our market capitalization plus our estimated control premium of 35% resulted in a fair value in excess of our carrying value by a margin of 27%. As a result, no impairment was indicated and we were not required to complete the second step of the goodwill impairment analysis. No goodwill impairment charges were recorded. The control premium used in our annual goodwill assessment at June 30, 2016 was based on a control premium study as of June 2014, resulting in a range of control premium of 30% to 40%. We reviewed the data and concluded that a 35% control premium best represented the amount an investor would likely pay, over and above market capitalization, in order to obtain a controlling interest given the economic conditions at that time.

During the third quarter of fiscal 2016, we reviewed recent control premium data for transactions that occurred during fiscal 2016 in the industries most comparable to our business (see Footnote 1 to our Consolidated Financial Statements). The data indicated that our current 35% control premium continues to be indicative of the amount that an investor would pay to obtain a controlling interest based on current macroeconomic and industry data.

During the fourth quarter of fiscal 2016, we assessed various qualitative factors to determine whether or not an additional goodwill impairment assessment was required as of September 30, 2016. We concluded that no additional goodwill impairment assessment was required. We continue to monitor our stock price on a daily basis. If the stock price remained below certain thresholds for a significant period of time, we would complete an interim impairment assessment. We also monitor other events or circumstances that could have a significant impact on our operations. If one of these events or circumstances were to occur, we would evaluate whether an interim goodwill impairment assessment should be completed.

CONTINGENT CONSIDERATION

We measure our contingent consideration liabilities recognized in connection with business combinations at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy as defined in ASC 320 “Investments - Debt and Equity Securities”. We used a probability-weighted discounted cash flow approach as a valuation technique to determine the fair value of the contingent consideration on the acquisition date. At each subsequent reporting period, the fair value is remeasured with the change in fair value recognized in general and administrative expense and interest expense in our Condensed Consolidated Statements of Operations. Amounts, if any, paid to the seller in excess of the amount recorded on the acquisition date will be classified as cash flows used in operating activities. Payments to the seller not exceeding the acquisition-date fair value of the contingent consideration will be classified as cash flows used in financing activities. At September 30, 2016, the fair value of our contingent consideration was $10.0 million. There was no contingent consideration at September 30, 2015.

INCOME TAXES

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

34

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

period of time to resolve and could result in adjustments to our income tax balances that are material to our consolidated financial position and results of operations and could result in potential cash outflows.

We have unrecognized tax benefits of $1.7 million at September 30, 2016. We expect that it is reasonably possible that the total amounts of unrecognized tax benefits will decrease approximately $0.7 million over the next 12 months due to the expiration of various statutes of limitations. The total amount of unrecognized tax benefits that if recognized would affect our effective tax rate is $1.6 million.  We recognize interest and penalties related to income tax matters in income tax expense.

WARRANTIES

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 repair or replace products we deem defective due 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 product warranty accrual was $1.0 million at both September 30, 2016 and 2015.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE RISK

Our exposure to interest rate risk relates primarily to our investment portfolio. We do not use derivative financial instruments to hedge against interest rate risk.

FOREIGN CURRENCY RISK

We are exposed to foreign currency transaction risk associated with certain sales being denominated in Euros, British Pounds, Japanese Yen or Canadian Dollar 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 manage our net asset or net liability position for non-functional currency accounts, primarily the U.S. dollar accounts in our foreign locations to reduce our foreign currency risk. We have not implemented a formal hedging strategy.

The table below compares the average monthly exchange rates of the Euro, British Pound, Japanese Yen and Canadian Dollar:

	Fiscal year ended September 30,		% increase
	2016	2015	(decrease)
Euro	1.1112	1.1499	(3.4	)%
British Pound	1.4261	1.5462	(7.8	)%
Japanese Yen	0.0090	0.0084	7.1	%
Canadian Dollar	0.7552	NA	NA

A 10.0% change from the 2016 average exchange rate for the Euro, British Pound, Yen and Canadian Dollar to the U.S. Dollar would have resulted in a 2.3% increase or decrease in fiscal 2016 annual revenue and a 2.3% increase or decrease in stockholders' equity at September 30, 2016. The above analysis does not take into consideration any pricing adjustments we may make in response to changes in the exchange rate.

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, money market funds, corporate bonds and government municipal 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.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Digi International Inc.

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows present fairly, in all material respects, the financial position of Digi International Inc. and its subsidiaries at September 30, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period ended September 30, 2016 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company did not maintain, in all material respects, effective internal control over financial reporting as of September 30, 2016, based on criteria established in Internal Control - Integrated Framework 2013 issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) because a material weakness in internal control over financial reporting related to inadequate segregation of duties for an individual who had access to create and post journal entries at a material subsidiary of the Company existed as of that date. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. The material weakness referred to above is described in Management's Report on Internal Control Over Financial Reporting appearing under Item 9A. We considered this material weakness in determining the nature, timing, and extent of audit tests applied in our audit of the 2016 consolidated financial statements, and our opinion regarding the effectiveness of the Company’s internal control over financial reporting does not affect our opinion on those consolidated financial statements. The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in management's report referred to above. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company's internal control over financial reporting based on our audits which were integrated audits in 2016 and 2015. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Business Description

We are a leading provider of Internet of Things (IoT) networking hardware products and solutions. We provide Machine-to-Machine (M2M) and IoT connections to solve business and mission-critical machine communication challenges for our customers that are reliable, secure, scalable and managed. We create secure, easy to implement embedded solutions and services to help customers build IoT connectivity. In addition, we deploy ready to use, complete box solutions to connect remote machinery. We also manage cloud services, offer professional services and complete IoT solutions. Our solutions are deployed by a wide range of businesses and institutions. Any business that utilizes a significant number of devices, whose operations could benefit from remote monitoring or control, may realize benefits from IoT networking.

Discontinued Operations

On October 23, 2015, we sold all of the outstanding stock of our wholly owned subsidiary, Etherios Inc. (“Etherios”) to West Monroe Partners, LLC. Because the sale of Etherios represented a strategic shift that will have a major effect on our operations and financial results, we have classified our Etherios business as discontinued operations, which requires retrospective application to financial information for all periods presented. Since the cost of segregating the consolidated statement of cash flows outweighed the benefits, we elected not to segregate our consolidated statement of cash flows as the material items in the operating and investing sections are disclosed in Note 3 to our Consolidated Financial Statements.

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 on our consolidated balance sheets with unrealized gains and losses recorded in accumulated other comprehensive loss within stockholders’ equity. In order to estimate the fair value for each security in our investment portfolio, we obtain quoted market prices and trading activity for each security where available. We obtain relevant information from our investment advisor and, if warranted, also may review the financial solvency of certain security issuers.

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 (expense) income.

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 equipment are depreciated over a period of three to five years. Building improvements and buildings are depreciated over ten and thirty-nine years, respectively.

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. 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 included in cost of sales in the Consolidated Statements of Operations. Amortization of all other acquired identifiable intangible assets is charged to operating expenses 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. There were no material impairments identified in fiscal 2016, 2015 or 2014.

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.  The calculation of goodwill impairment requires us to make assumptions about the fair value of our one reporting unit, which historically has been approximated by using our market capitalization plus a control premium. Control premium assumptions require judgment and actual results may differ from assumed or estimated amounts.

Our test for potential goodwill impairment is a two-step approach. We estimate the fair value for our one reporting unit by comparing its fair value (market capitalization plus control premium) to our carrying value. If the carrying value of the reporting unit exceeds its estimated fair value, the second step of the goodwill impairment analysis requires us to measure the amount of the impairment loss. An impairment loss is calculated by comparing the implied fair value of the goodwill to its carrying amount. To calculate the implied fair value of goodwill, the fair value of the reporting unit's assets and liabilities, excluding goodwill, is estimated. The excess of the fair value of the reporting unit over the amount assigned to its assets and liabilities, excluding goodwill, is the implied fair value of the reporting unit's goodwill.

In June 2014, we performed a control premium study to determine the appropriate control premium to include in the calculation of fair value. We used 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, the following three methodologies were used: (1) analysis of individual transactions within our industry; (2) analysis of industry-wide data, and (3) analysis of global transaction data. Individual

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

transactions in the Communication Equipment or Technology Hardware, Storage and Peripherals industries were used to find transactions of target companies that operated in similar markets and shared similar operating characteristics with us. 

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

• Transactions announced between June 30, 2009 and the valuation date.

In analyzing industry-wide data, transactions in the following 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. The control premium analysis resulted in a range of control premium of 30% to 40%. We reviewed the data and concluded that a 35% control premium best represented the amount an investor would likely pay, over and above market capitalization, in order to obtain a controlling interest given the economic conditions at that time.

During the third quarter of fiscal 2016, we reviewed recent control premium data for transactions that occurred during fiscal 2016 in the industries previously described. The data indicated that our 35% control premium continued to be indicative of the amount that an investor would pay to obtain a controlling interest based on current macroeconomic and industry data.

At June 30, 2016, our market capitalization was $278.6 million compared to our carrying value of $294.9 million. Our market capitalization plus our estimated control premium of 35% resulted in a fair value in excess of our carrying value by a margin of 27%. We concluded that no impairment was indicated and we were not required to complete the second step of the goodwill impairment analysis. No goodwill impairment charges were recorded. During the fourth quarter of fiscal 2016, we assessed various qualitative factors to determine whether or not an additional goodwill impairment assessment was required as of September 30, 2016, and we concluded that no additional impairment assessment was required.

We continue to monitor our stock price on a daily basis. If the stock price remained below certain thresholds for a significant period of time, we would complete an interim impairment assessment. We also monitor other events or circumstances that could have a significant impact on our operations. If one of these events or circumstances were to occur, we would evaluate whether an interim goodwill impairment assessment should be completed.

If our stock price or control premium declines, the first step of our goodwill impairment analysis may fail. We have identified factors that could result in additional interim goodwill impairment testing. For example, we would perform the second step of the impairment testing if our stock price fell below certain thresholds for a significant period of time, or if our control premium significantly decreased. Events or circumstances may occur that could negatively impact our stock price, including changes in our anticipated revenues and profits and our ability to execute on our strategies. In addition, our control premium could decline due to changes in economic conditions in the technology industry or more generally in the financial markets. An impairment could have a material effect on our consolidated balance sheet and results of operations. We have had no goodwill impairment losses since the adoption of Accounting Standards Codification (ASC) 350, Intangibles-Goodwill and Others, in fiscal 2003.

Contingent Consideration

We measure our contingent consideration liabilities recognized in connection with business combinations at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy as defined in ASC 320 “Investments - Debt and Equity Securities”. We used a probability-weighted discounted cash flow approach as a valuation technique to determine the fair value of the contingent consideration on the acquisition date. At each subsequent reporting period, the fair value is remeasured with the change in fair value recognized in general and administrative expense and interest expense in our Condensed Consolidated Statements of Operations. Amounts, if any, paid to the seller in excess of the amount recorded on the acquisition date will be classified as cash flows used in operating activities. Payments to the seller not exceeding the acquisition-date fair value of the contingent consideration will be classified as cash flows used in financing activities.

Warranties

In general, we warrant our hardware 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 hardware 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.

Revenue Recognition

We recognize revenue in accordance with authoritative guidance issued by FASB related to revenue recognition.

Hardware product revenue as a percentage of total revenue was 96.6%, 95.9% and 94.4% in fiscal 2016, 2015 and 2014, respectively. We recognize hardware 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.

Sales to authorized domestic and foreign 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 and distribution sales for the current period. Estimated reserves for future returns and price adjustments are charged against revenue in the same period as the corresponding revenue is recorded.

Service revenue as a percentage of total revenue represented 3.4%, 4.1% and 5.6% in fiscal 2016, 2015 and 2014, respectively. Our service revenue is derived primarily from our wireless design services and our Digi Cold Chain Solutions. We also have some service revenue that is derived from our Digi Device Cloud™, which is a platform-as-a-service (PaaS) offering in which customers pay for services consumed in terms of devices being managed and monitored, or as a monthly service fee for access to information.  In addition, we have small amounts of revenue from our support services. We recognize service revenue from our wireless design services, Digi Cold Chain Solutions and Device Cloud based upon performance, including final product delivery and customer acceptance.  In addition, we recognize small amounts of revenue from our support services which is recognized over the life of the contract, and training as the services are performed.

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.

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 functional currency. Assets and liabilities of these operations are translated at the exchange rates in effect at the end of each reporting period. For our larger international subsidiaries, statements of operations accounts are translated at the daily rate. For all other international subsidiaries, our 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 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 2016, 2015 and 2014, there were net transaction (losses) gains of $(0.7) million, $0.6 million and $0.5 million, respectively, that were recorded in other (expense) income, net. We manage our net asset or net liability position for U.S. dollar accounts in our foreign locations to reduce our foreign currency risk. We have not implemented a formal hedging strategy.

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 restricted stock units. 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.

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):

Because their effect would be anti-dilutive at period end, certain potentially dilutive shares related to stock options to purchase common shares were excluded 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, 2016, 2015 and 2014, such excluded stock options were 1,519,691, 3,016,911 and 3,284,993, respectively.

Use of Estimates and Risks and Uncertainties

The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United 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 amount of revenue 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 loss account in stockholders’ equity.

Recent Accounting Developments

Adopted

In November 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” ASU 2015-17 simplified the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as non-current in the balance sheet. The amendments in this Update are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods and may be applied either prospectively to all deferred tax assets and liabilities or retrospectively to all periods presented. Early adoption is permitted. We elected to early adopt ASU 2015-17 beginning in the fiscal quarter ending December 31, 2015. Other than the revised balance sheet presentation of deferred tax assets and liabilities from current to non-current, the adoption of this standard did not have a material impact to our consolidated financial statements.

In September 2015, FASB issued ASU 2015-16, “Simplifying the Accounting for Measurement-Period Adjustments.” To simplify the accounting for adjustments made to provisional amounts recognized in a business combination, the amendments in this update eliminate the requirement to retrospectively account for those adjustments. The amendments in this update are effective for fiscal years beginning after December 15, 2015, including interim periods within those years, which for us will be the first fiscal quarter ending December 31, 2016. Earlier application is permitted for financial statements that have not been issued. We elected to early adopt ASU 2015-16 beginning the fiscal quarter ending December 31, 2015. The adoption of this standard did not have a material impact to our consolidated financial statements.

Not Yet Adopted

In August 2016, FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments.” The amendments in this update provided guidance on eight specific cash flow issues. This update is to provide specific guidance on each of the eight issues, thereby reducing the diversity in practice in how certain transaction are classified in the statement of cash flows. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2017, which for us is the first quarter ended December 31, 2018. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2016-15 on our consolidated financial statements.

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments.” The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses. This update is intended to provide financial statement users with more decision-useful information about the expected credit losses. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2019, which for us is

the first quarter ended December 31, 2020. Entities may early adopt beginning after December 15, 2018. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements.

In March 2016, FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting.” This update includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2016, which for us is the first fiscal quarter ending December 31, 2017. Early adoption is permitted. We will adopt ASU 2016-09 beginning October 1, 2017. We are currently evaluating the impact of the adoption of ASU 2016-09 on our consolidated financial statements. Prospectively, beginning October 1, 2017, excess tax benefits and tax deficiencies will be reflected as income tax benefit or expense in our Consolidated Statement of Operations and could result in a material impact. The extent of the excess tax benefits or tax deficiencies are subject to variation in our stock price and the timing of RSU vestings and employee stock option exercises.

In February, 2016, FASB issued ASU 2016-02, “Leases (Topic 842)”, which amends the existing guidance to require lessees to recognize lease assets and lease liabilities from operating leases on the balance sheet. This ASU is effective using the modified retrospective approach for annual periods and interim periods within those annual periods beginning after December 15, 2018, which for us is the first fiscal quarter ending December 31, 2019. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2016-02 on our consolidated financial statements.

In January 2016, FASB issued ASU 2016-01, “Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 will require equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. The amendments in this update will also simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, eliminate the requirement for public business entities to disclose the method and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet and require these entities to use the exit price notion when measuring fair value of financial instruments for disclosure purposes. This ASU would also change the presentation and disclosure requirements for financial instruments. In addition, this ASU clarifies the guidance related to valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, which for us is the first fiscal quarter ending December 31, 2018. Early adoption is permitted for financial statements of fiscal years and interim periods that have not been issued. We are currently evaluating the impact of the adoption of ASU 2016-01.

In July 2015, FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” This provision would require inventory that was previously recorded using first-in, first-out (“FIFO”) to be recorded at lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This guidance is effective for fiscal years beginning after December 15, 2016 and interim periods within those years, which for us will be the first fiscal quarter ending December 31, 2017. The amendments in this guidance should be applied prospectively with earlier application permitted as of the beginning of an interim or annual period. We are currently evaluating the impact of the adoption of ASU 2015-11 and whether it would have a material impact on our consolidated financial statements.

In April 2015, FASB issued ASU 2015-05, “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” The new standard provides guidance to customers about whether a cloud computing arrangement includes a software license. If the arrangement does include a software license, the software license element of the arrangement should be accounted for in the same manner as the acquisition of other software licenses. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, with early adoption permitted. We expect to adopt this guidance beginning with our fiscal quarter ending December 31, 2016. We do not expect this guidance to have a material impact on our consolidated financial statements.

In August 2014, FASB issued ASU 2014-15, “Presentation of Financial Statements - Going Concern.” This guidance requires management to evaluate whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. These amendments are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter, which for us, will be our annual period ended September 30, 2017. Early adoption is permitted. While we are evaluating the impact of the adoption of ASU 2014-15, we do not expect it to have an impact on our consolidated financial statements.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

In May 2014, FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” This guidance provides a five-step analysis in determining when and how revenue is recognized so that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods and services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued ASU 2015-14 “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date” which approved a one-year deferral of the effective date of ASU 2014-09. As a result of this deferral, ASU 2014-09 is effective for our fiscal 2019, including interim periods within that reporting period. The FASB also agreed to allow us to choose to adopt the standard effective for our fiscal 2018. In addition, the FASB issued ASU 2016-08, ASU 2016-10 and ASU 2016-12 in March 2016, April 2016 and May 2016, respectively, to provide interpretive clarifications on the new guidance in ASC Topic 606. We are currently working through an adoption plan and have identified our revenue streams and completed a preliminary analysis of how we currently account for revenue transactions compared to the revenue accounting required under the new standard.  We intend to complete our adoption plan in fiscal 2017.  This plan includes a review of transactions supporting each revenue stream to determine the impact of accounting treatment under ASC 606, evaluation of the method of adoption, and completing a rollout plan for implementation of the new standard with affected functions in our organization.  Because of the nature of the work that remains, at this time we are unable to reasonably estimate the impact of adoption on our consolidated financial statements.  We plan to adopt the new guidance beginning October 1, 2018.

2. ACQUISITION

Acquisition of Bluenica Corporation

On October 5, 2015 we purchased all of the outstanding stock of Bluenica Corporation (“Bluenica”), a company focused on temperature monitoring of perishable goods in the food industry by using wireless sensors which are installed in grocery and convenience stores, restaurants, and in products during shipment and storage to ensure that quality, freshness and public health requirements are met.  This acquisition forms the basis for our Digi Cold Chain Solutions.

The terms of the acquisition included an upfront cash payment together with earn-out payments.  Cash of $2.9 million was paid at time of closing.  The earn-out payments are scheduled to be paid in installments over a four-year period based on revenue achievement of the acquired business. Each of the earn-out payments will be calculated based on the revenue performance of Digi Cold Chain Solutions for each respective earn-out period. The cumulative amount of these earn-out payments will not exceed $11.6 million.  An additional payment, not to exceed $3.5 million, may also be due depending on revenue performance. The fair value of this contingent consideration was $10.4 million at the date of acquisition (see Note 8 to the Consolidated Financial Statements). We have determined that the earn-out will be considered as part of the purchase price consideration as there are no continuing employment requirements associated with the earn-out. Costs directly related to the acquisition, including legal, accounting and valuation fees, of approximately $0.1 million have been charged directly to operations and are included in general and administrative expense in our Condensed Consolidated Statements of Operations in fiscal 2016.

The purchase price was allocated to the estimated fair value of assets acquired and liabilities assumed. The purchase price allocation resulted in the recognition of $11.0 million of goodwill. We believe that the acquisition resulted in the recognition of goodwill because this is a complementary acquisition for us and will provide a source of recurring revenue in a new vertical market.

Operating results for Bluenica, now known as Digi Cold Chain Solutions, are included in our Consolidated Statements of Operations from October 6, 2015. The Consolidated Balance Sheet as of September 30, 2016 reflects the final allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition.

The Bluenica acquisition has been accounted for using the acquisition method of accounting, which requires, among other things, that assets acquired and liabilities assumed pursuant to the stock purchase agreement be recognized at fair value as of the acquisition date. During the third quarter of fiscal 2016, we finalized the purchase price allocation by recording adjustments to our deferred tax liabilities account as a result of the completion and filing of the last annual tax return for Bluenica.

2. ACQUISITION (CONTINUED)

The following table summarizes the values of Bluenica assets acquired and liabilities assumed as of the acquisition date (in thousands):

Cash	$	2,888
Purchase price payable upon completion of diligence matters	115
Fair value of contingent consideration on acquired business	10,400
Total purchase price consideration	$	13,403
Fair value of net tangible assets acquired	$	129
Fair value of identifiable intangible assets acquired:
Purchased and core technology	2,000
Customer relationships	900
Goodwill	10,985
Deferred tax liabilities, net	(611		)
Total	$	13,403

The weighted average useful life for all the identifiable intangibles listed above is 5.6 years. For purposes of determining fair value, the purchased and core technology identified above is assumed to have a useful life of five years and the customer relationships are assumed to have useful lives of seven years. 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.

The following unaudited pro forma condensed consolidated results of operations for fiscal 2015 have been prepared as if the acquisition of Bluenica had occurred at the beginning of fiscal 2015. Pro forma adjustments include amortization of identifiable intangible assets.

(1) Earnings per share presented are calculated by line item and may not add due to the use of rounded amounts.

Since the acquisition of Bluenica occurred close to the beginning of our fiscal 2016, we believe that the proforma amounts would be not be materially different from actual amounts. Revenue for fiscal 2016 related to the Bluenica acquisition was $0.7 million. As our operating costs related to the Bluenica acquisition are now integrated, operating income and related earnings per share for Bluenica are not determinable for fiscal 2016.

3. DISCONTINUED OPERATIONS

On October 23, 2015, we sold all the outstanding stock of our wholly owned subsidiary, Etherios to West Monroe Partners, LLC. We sold Etherios as part of a strategy to focus on providing highly reliable machine connectivity solutions for business and mission-critical application environments. Etherios was included in our single operating segment.

The terms of the sale agreement provide that West Monroe Partners LLC will pay us $3.0 million on October 23, 2016 and $2.0 million on October 23, 2017. The present value of these amounts is included within the total fair value of consideration received. These receivable amounts are unsecured and non-interest bearing. The carrying value of these receivables presented on our Consolidated Balance Sheet at September 30, 2016 approximated their fair values, which were determined using level 3 cash flow fair value measurement techniques. We received the first payment of $3.0 million on October 21, 2016.

Goodwill has been included in the net assets of Etherios based on the relative fair value of Etherios compared to the fair value of the Company, as the Company consists of a single reporting unit for goodwill impairment testing purposes.

As a condition to the sale agreement, we retained the operating leases in the Dallas and Chicago locations. Digi is no longer using these facilities and has sublet the Dallas location to West Monroe Partners, LLC through December 31, 2017. Also in connection with the sale, we assigned our San Francisco lease to West Monroe Partners, LLC. A remaining potential obligation exists in the event of a default under the assigned lease. However, we believe the likelihood of a liability related to this lease is remote. As of September 30, 2016, the future minimum lease payments for the San Francisco lease are approximately $0.1 million.

Income (loss) from discontinued operations, after income taxes, as presented in the Consolidated Statements of Operations for the twelve months ended September 30, 2016, 2015 and 2014 is as follows (in thousands):

3. DISCONTINUED OPERATIONS (CONTINUED)

Income tax benefit on discontinued operations for the twelve months ended September 30, 2016 was $0.5 million and primarily represented income tax benefits for deductible transaction costs, partially offset by a tax expense for equity awards for which we will not receive a tax deduction. For tax purposes, this transaction resulted in a capital loss of $13.7 million, as the tax basis of the Etherios stock was higher than the book basis of the assets that were sold. Since we do not expect to be able to utilize this capital loss in the five year carryforward period, a deferred tax asset offset by a full valuation allowance of $5.1 million was recorded in the third quarter of fiscal 2016 upon completion of the capital loss calculation.

At September 30, 2015, the carrying amounts of major classes of assets and liabilities of discontinued operations included in the Consolidated Balance Sheet was as follows (in thousands):

5. SEGMENT INFORMATION AND MAJOR CUSTOMERS

We operate under a single operating and reporting segment.  Our revenue consists of hardware product revenue and service revenue. In an effort to provide further transparency of our financial information, beginning the first quarter of fiscal 2016, we transitioned away from reporting revenue in terms of growth and mature hardware products and now report four product categories: Cellular routers and gateways, Radio Frequency (RF), Embedded and Network. We believe this is a more meaningful presentation and reflects how we are monitoring our revenue.

Our cellular product category includes cellular routers and all gateways, and the RF product category includes XBee^® modules as well as other RF solutions. The embedded product category includes Digi Connect^® and Rabbit^® embedded systems on

7. 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, we obtain quoted market prices and trading activity for each security where available. We obtain relevant information from our investment advisor and, if warranted, also may review the financial solvency of certain security issuers. As of September 30, 2016, 18 of our 48 securities that we held 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 current marketable securities are scheduled to mature in less than one year and our non-current marketable securities are scheduled to mature in less than two years. We received proceeds from the sale of our available-for-sale marketable securities of $73.7 million, $38.0 million and $47.4 million for fiscal 2016, 2015 and 2014, respectively.

8. 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 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 and to financial liabilities for contingent consideration. 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 and liabilities that are measured at fair value on a recurring basis (in thousands):

Our money market funds, which have been determined to be 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 into or out of our Level 2 financial assets during the twelve months ended September 30, 2016.

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 or contingent consideration, currently and in the future. If market conditions deteriorate, we may incur impairment charges for securities in our investment portfolio. We may also incur changes to our contingent consideration liability as discussed below.

In connection with the Bluenica acquisition discussed in Note 2, we are required to make contingent payments over a period of up to four years, subject to Digi Cold Chain Solutions achieving specified revenue thresholds. The fair value of the liability for contingent payments recognized upon acquisition was $10.4 million, and was estimated by discounting to present value the probability-weighted contingent payments expected to be made. Assumptions used in this calculation included the discount rate and various probability factors. This liability is considered to be a Level 3 financial liability that is re-measured each reporting period.

The following table presents a reconciliation of the liability measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the twelve months ended September 30, 2016 (in thousands):

	Twelve months ended September 30, 2016
Fair value at beginning of period	$	—
Purchase price contingent consideration	10,400
Change in fair value of contingent consideration	(440		)
Fair value at end of period	$	9,960

The change in fair value of contingent consideration for the acquisition of Bluenica is included in general and administrative and interest expense on our Condensed Consolidated Statements of Operations and reflects our estimate of the probability of achieving the relevant targets and is discounted based on our estimated discount rate. We have estimated the fair value of the contingent consideration based on the probability of achieving the specified revenue thresholds at 75.8% to 98.0%. A significant increase (decrease) in our estimates of achieving the relevant targets could materially increase (decrease) the fair value of the contingent consideration liability.

2016 Restructuring

On January 19, 2016, we approved a restructuring plan for our wireless design services group. This plan resulted in an elimination of 5 positions. We recorded a restructuring charge of $0.1 million related to severance during the second quarter of fiscal 2016 and paid the majority of the severance during that same quarter.

On November 19, 2015, we approved a restructuring plan impacting our corporate staff. The plan closed our Dortmund, Germany office and relocated certain employees to our Munich office. We also recorded a contract termination charge as we relocated employees in our Minneapolis, Minnesota office to our World Headquarters in Minnetonka, Minnesota in December 2015. We recorded a restructuring charge of $0.7 million that included $0.5 million of severance and $0.2 million of contract termination costs during the first quarter of fiscal 2016. This restructuring resulted in an elimination of 10 positions. The payments associated with these charges were completed in the third quarter of fiscal 2016.

2015 Restructuring

On January 22, 2015, we announced the closure of our India location. The March closure resulted in the elimination of approximately 38 employees from engineering, sales and administration. We recorded a restructuring charge of $0.4 million related to severance during the second quarter of fiscal 2015. The payments associated with this charge were completed during the third quarter of fiscal 2015.

2014 Restructuring

On October 31, 2013, we announced our intention to restructure certain of our operations in India. The restructuring was primarily associated with cost reduction initiatives resulting in the elimination of approximately 40 engineering and sales positions in our work force. We recorded a restructuring charge of $0.2 million related to severance during the first quarter of fiscal 2014. The payments associated with these charges and all the actions associated with the restructuring were completed during the third quarter of fiscal 2014.

2013 Restructuring

On September 27, 2013, we announced our intention to restructure certain of our operations in the U.S. The restructuring was primarily associated with cost reduction initiatives and resulted in the elimination of 15 positions in our work force. We recorded a restructuring charge of $0.4 million for severance during the fourth quarter of fiscal 2013. The payments associated with these charges and all the actions associated with the restructuring along with a reversal of $0.1 million were completed during the first quarter of fiscal 2014.

Net deferred tax asset	$	6,679		$	9,336

As of September 30, 2016, we have estimated carryforwards for tax purposes as follows: We have $0.9 million of carryforwards mostly related to state research and development tax credits and carryforwards consisting of a U.S. capital loss of $5.1 million and non-U.S. net operating losses of $0.3 million. The majority of the state research and development tax credits and non-U.S. net operating losses have an unlimited carryforward period. Our non-U.S. tax credit carryforwards will expire in 2028. Our U.S. capital loss carryforward will expire in 2020.

Our valuation allowance for certain U.S. and foreign locations increased to $6.0 million at September 30, 2016 from $0.9 million at September 30, 2015, primarily due to the capital loss realized on the sale of Etherios. We are not expecting to generate sufficient capital gains within the carryforward period to fully utilize the capital loss. The amount of the deferred tax assets 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.

11. INCOME TAXES (CONTINUED)

During fiscal 2016, we recorded net tax benefits of $1.5 million, primarily from the reinstatement of the federal research and development tax credit for calendar year 2015 and the reversal of tax reserves due to the expiration of statutes of limitation from U.S. and foreign tax jurisdictions. In addition, we filed amended income tax returns resulting in an additional domestic refund related to qualified manufacturing activities. These benefits are included within the discrete tax benefits in the above table.

During fiscal 2015, we recorded net tax benefits of $0.8 million, resulting from the reinstatement of the research and development tax credit for calendar year 2014, reversal of tax reserves due to the expiration of statute of limitations from U.S. and foreign tax jurisdictions and reversal of tax reserves due to the resolution of tax audits. These benefits are included within the discrete tax benefits in the above table.

During fiscal 2014, we recorded net tax benefits of $1.5 million related to the re-measurement and reversal of certain income tax reserves as a result of a federal income tax audit of fiscal 2012, the reassessment of state research and development tax credits and the release of income tax reserves due to the expiration of statute of limitations from U.S. and foreign tax jurisdictions. These benefits are included within the discrete tax benefits in the above table.

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

	Fiscal years ended September 30,
	2016			2015			2014
Unrecognized tax benefits at beginning of fiscal year	$	1,618		$	2,301		$	3,332

Settlements	(30		)	(74		)	(95		)
Expiration of statute of limitations	(156		)	(608		)	(160		)
Unrecognized tax benefits at end of fiscal year	$	1,708		$	1,618		$	2,301

The total amount of unrecognized tax benefits at September 30, 2016 that, if recognized, would affect our effective tax rate is $1.6 million. We expect that it is reasonably possible that the total amounts of unrecognized tax benefits will decrease approximately $0.7 million over the next 12 months due to the expiration of various statutes of limitations.

Of the $1.7 million of unrecognized tax benefits, $1.3 million is included in non-current income taxes payable and $0.4 million is included with non-current deferred tax assets on the consolidated balance sheet at September 30, 2016.

We recognize interest and penalties related to income tax matters in income tax expense. During fiscal 2016 and 2015, 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 of $0.2 million at September 30, 2016 and $0.3 million at September 30, 2015. These accrued interest and penalties are included in our non-current income taxes payable on our consolidated balance sheets.

We operate in multiple tax jurisdictions both in the U.S. and outside of the U.S and face audits from various tax authorities regarding transfer pricing, tax credits, and other matters. 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. With a few exceptions, we are no longer subject to income tax examination for tax years prior to fiscal 2013. For state tax authorities, most notably in California and Texas, generally we are no longer subject to income tax examination for tax years before fiscal 2012, and for Minnesota for tax years prior to fiscal 2014. We do not anticipate significant changes to our unrecognized tax benefits as a result of these examinations.

11. INCOME TAXES (CONTINUED)

At September 30, 2016, we had approximately $31.5 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 or intention to repatriate historical earnings in the form of cash to the United States, if we change our assertion from indefinitely reinvesting undistributed foreign earnings, 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 up to $0.6 million.

12. STOCK-BASED COMPENSATION

During fiscal 2016, stock-based awards were granted under our 2016 Omnibus Incentive Plan (the “2016 Plan”), as well as our 2014 Omnibus Incentive Plan (the “2014 Plan”). Grants under the 2014 Plan ceased upon stockholder approval of the 2016 Plan during the second quarter of fiscal 2016. The authority to grant options under the 2016 Plan and set other terms and conditions rests with the Compensation Committee of the Board of Directors. We also have awards outstanding under our 2013 Omnibus Incentive Plan (the “2013 Plan”), 2000 Omnibus Stock Plan, as amended and restated as of December 4, 2009 (the “2000 Plan”), and the Stock Option Plan, as amended and restated as of November 27, 2006 (the “Stock Option Plan”) and our Non-Officer Stock Option Plan as amended and restated as of November 27, 2006 (the “Non-Officer Plan”).

The 2016 Plan initially authorized the issuance of up to 1,500,000 common shares in connection with awards of stock options, stock appreciation rights, restricted stock, restricted stock units, performance-based full value awards or other stock-based awards. Eligible participants include our employees, our affiliates, non-employee directors of our Company and any consultant or advisor who is a natural person and provides services to us or our affiliates. Options that have been granted under the 2016 Plan typically vest over a four-year period and will expire if unexercised after seven years from the date of grant. Restricted stock unit awards (“RSUs”) that have been granted to directors typically vest in one year. RSUs that have been granted to executives and employees typically vest in November over a four-year period. Awards may be granted under the 2016 Plan until January 31, 2026. Options under the 2016 Plan can be granted as either incentive stock options (“ISOs”) or non-statutory stock options (“NSOs”). The exercise price of options and the grant date price of restricted stock is determined by our Compensation Committee but may not be less than the fair market value of our common stock based on the closing price on the date of grant. Upon exercise, we issue new shares of stock. As of September 30, 2016, there were approximately 1,450,982 shares available for future grants under the 2016 Plan.

The 2014 Plan initially authorized the issuance of up to 2,250,000 common shares in connection with awards of stock options, stock appreciation rights, restricted stock, restricted stock units, performance-based full value awards or other stock-based awards. Eligible participants included our employees, our affiliates, non-employee directors of our Company and any consultant or advisor who is a natural person and provides services to us or our affiliates. Options granted under this plan generally vested over a four year service period and expired if unexercised after eight years from the date of grant. Restricted stock awards (RSU's) that were granted to Directors typically vested in one year. RSU's that were granted to executives and employees typically vested in November over a four-year period. Options under the 2014 Plan were granted as either incentive stock options (ISOs) or non-statutory stock options (NSOs). Awards may no longer be granted under the 2014 Plan as the plan was terminated effective February 1, 2016 at the Annual Meeting of Stockholders. The exercise price of options and the grant date price of restricted stock was determined by our Compensation Committee but could not be less than the fair market value of our common stock based on the closing price on the date of grant.

The 2013 Plan initially authorized the issuance of up to 1,750,000 common shares in connection with awards of stock options, stock appreciation rights, restricted stock, restricted stock units, performance-based full value awards or stock awards. Eligible participants included our employees, non-employee directors, consultants and advisors. Options granted under this plan generally vested over a four year service period and expired if unexercised after eight years from the date of grant. RSU's that were granted to Directors typically vested in one year. Awards may no longer be granted under the Incentive Plan as the plan was terminated effective January 27, 2014 at the Annual Meeting of Stockholders. Options under the 2013 Plan were granted as either ISOs or NSOs. The exercise price was determined by our Compensation Committee but could not be less than the fair market value of our common stock based on the closing price on the date of grant.

The 2000 Plan initially authorized 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 included our employees, non-employee directors, consultants and advisors. An authorization to issue an additional 2,500,000 common shares was ratified on January 25, 2010 at the Annual Meeting of Stockholders. Awards may no longer be granted under the 2000 Plan as

the plan was terminated as to future awards on January 28, 2013 at the Annual Meeting of Stockholders. Options under the 2000 Plan were granted as either ISOs or non-statutory stock options NSOs. The exercise price was determined by our Compensation Committee but could not be less than the fair market value of our common stock based on the closing price on the date of grant.

Awards outstanding under the Stock Option Plan and the Non-Officer Plan included NSOs. In addition, the Stock Option Plan also included ISOs to employees and others who provided services to us, including consultants, advisers and directors. Options granted under these plans generally vested over a four year service period and will expire if unexercised after ten years from the date of grant. 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.

Our equity plans and corresponding forms of award agreements generally have provisions allowing employees to elect to satisfy tax withholding obligations through the delivery of shares, having us retain a portion of shares issuable under the award or paying cash to us for the withholding. During fiscal 2016 and 2015, our employees forfeited 47,464 shares and 9,371 shares, respectively in order to satisfy $0.6 million and $0.1 million, respectively, of withholding tax obligations related to stock-based compensation, pursuant to terms of awards under our board and shareholder-approved compensation plans. No shares were forfeited to satisfy withholding obligations during fiscal 2014.

We recorded cash received from the exercise of stock options of $7.2 million, $6.6 million and $3.7 million during fiscal years 2016, 2015 and 2014, respectively. During fiscal 2016, there were $0.2 million of excess tax benefits from stock-based compensation. The were no excess tax benefits from stock-based compensation during fiscal 2015 and excess tax benefits were minimal during fiscal year 2014.

We sponsor an Employee Stock Purchase Plan, as amended and restated as of October 29, 2013, 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 most recent amendments to the Purchase Plan, ratified by our stockholders on January 27, 2014, increased the total number of shares to 2,800,000 that may be purchased under the plan. Employee contributions to the Purchase Plan were $0.9 million in both fiscal 2016 and 2015, and $1.0 million in fiscal 2014. Pursuant to the Purchase Plan, 103,915, 123,847, and 129,449 shares of common stock were issued to employees during fiscal 2016, 2015 and 2014, respectively. Shares are issued under the Purchase Plan from treasury stock. As of September 30, 2016, 513,616 shares of common stock were available for future issuances under the Purchase Plan.

Stock-based compensation cost capitalized as part of inventory was immaterial as of September 30, 2016, 2015 and 2014.

The following table summarizes our stock option activity (in thousands, except per common share amounts):

Exercisable at September 30, 2016	2,857		$10.49	3.7	$	4,158

(1) The aggregate intrinsic value represents the total pre-tax intrinsic value, based on our closing stock price of $11.40 as of September 30, 2016, 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, 2016, 2015 and 2014 was $1.9 million, $0.9 million and $0.5 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:

	Fiscal years ended September 30,
	2016		2015		2014
Weighted average per option grant date fair value	$	3.90	$	2.98	$	4.35
Assumptions used for option grants:
Risk free interest rate	1.22% - 1.85%		1.57% - 1.85%		1.76% - 2.02%
Expected term	6.00 years		6.00 years		6.00 years
Expected volatility	32% - 33%		32% - 36%		38% - 40%
Weighted average volatility	32%		35%		40%
Expected dividend yield	0		0		0

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 our stock. We use historical data to estimate option exercise and employee termination information within the valuation model. 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.

We use historical data to estimate pre-vesting forfeiture rates. The pre-vesting forfeiture rate used in fiscal 2016 was 10.0%. As of September 30, 2016, the total unrecognized compensation cost related to non-vested stock-based compensation arrangements, net of expected forfeitures, was $2.9 million and the related weighted average period over which it is expected to be recognized was approximately 3.0 years.

13. COMMON STOCK REPURCHASE

Common Stock Repurchase Program

On October 29, 2013, our Board of Directors authorized a program to repurchase up to $20.0 million of our common stock, primarily to support our employee stock purchase program and to return capital to shareholders. During the first quarter of fiscal 2015, we repurchased 287,787 shares for $2.2 million under this plan which expired on October 31, 2014.

On October 28, 2014, our Board of Directors authorized a program to repurchase up to $15.0 million of our common stock primarily to return capital to shareholders and to support our employee stock purchase program. This authorization began on November 1, 2014 and expired on October 31, 2015. There were no shares repurchased under this program.

On April 26, 2016, our Board of Directors authorized a program to repurchase up to $15.0 million of our common stock primarily to return capital to shareholders. This authorization expires on May 1, 2017. Shares repurchased under this program may be made through open market and privately negotiated transactions from time to time and in amounts that management deems appropriate. The amount and timing of share repurchases, if any, depends upon market conditions and other corporate considerations. There were no shares repurchased under this program as of September 30, 2016.

14. SHARE RIGHTS PLAN

Under our share rights plan, each right entitles its holder to buy one one-hundredth of a share of a Series A Junior Participating Preferred Stock at an exercise price of $60, subject to adjustment. The rights are not exercisable until a specified distribution date as defined in the Share Rights Agreement. The Rights will expire on June 30, 2018, unless extended or earlier redeemed or exchanged by us as defined in the Share Rights Agreement.

15. EMPLOYEE BENEFIT PLANS

We currently have a savings and profit sharing plan pursuant to Section 401(k) of the Internal Revenue Code (the Code), whereby eligible employees may contribute up to 25% of their pre-tax earnings, not to exceed amounts allowed under the Code.

We provide a match of 100% on the first 3% of each employee’s bi-weekly contribution and a 50% match on the next 2% of each employee’s bi-weekly contribution. In addition, we may make contributions to the plan at the discretion of the Board of Directors. We provided matching contributions of $1.4 million for fiscal 2016, $1.7 million for fiscal 2015 and $1.6 million for fiscal 2014.

16. COMMITMENTS

We have entered into various operating lease agreements for office facilities and equipment, the last of which expires in fiscal 2020. The office facility leases generally require us to pay a pro-rata share of the lessor’s operating expenses. Certain operating leases contain escalation clauses and are being amortized on a straight-line basis over the term of the lease.

The following schedule reflects future minimum rental commitments under noncancelable operating leases (in thousands):

Fiscal year	Amount
2017	$	1,706
2018	958

17. CONTINGENCIES

Patent Infringement Lawsuits

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. While we are unable to predict the outcome of any potential claims or litigation due to the inherent unpredictability of these matters, we believe that it is possible that we could, in the future, incur judgments or enter into settlements of claims that could have a material adverse effect on our operations in any particular period.

(1) During fiscal 2016 and 2015, we recorded net tax benefits of $1.5 million and $0.8 million, respectively. We recorded a benefit of $0.7 million in the first quarter of fiscal 2016 resulting from the reinstatement of the research and development tax credit for calendar year 2015, reversal of income tax reserves due to the expiration of the statute of limitations from various U.S. and foreign tax jurisdictions and reversal of tax reserves due to the resolution of tax audits. In the third quarter of fiscal 2016, we recorded a tax benefit of $0.5 million primarily due to the filing of an amended income tax return resulting in a domestic refund related to qualified manufacturing activities. In the fourth quarter of fiscal 2016, we recorded a net tax benefit of $0.2 million, primarily due to the filing of an additional amended income tax return resulting in an additional domestic refund related to qualified manufacturing activities, partially offset by an adjustment of the state rate on net deferred tax assets. We recorded net tax benefits of $0.5 million in the first quarter of fiscal 2015 resulting from the reinstatement of the research and development tax credit for calendar year 2014, reversal of income tax reserves due to the expiration of the statute of limitations from various U.S. and foreign tax jurisdictions and reversal of tax reserves due to the resolution of tax audits. In the third quarter of fiscal 2015, we recorded a tax benefit of $0.4 million primarily due to the reversal of reserves for state research and development tax credits and transfer pricing, partially offset by an adjustment of the state rate on net deferred tax assets.

19. SUBSEQUENT EVENT

Acquisition of FreshTemp, LLC

On November 1, 2016, we purchased all of the outstanding stock of FreshTemp, LLC, a Pittsburgh-based provider of temperature monitoring and task management solutions for the food industry. We believe this is a complementary acquisition for us as the acquired technology will continue to be supported to create an advanced portfolio of products for the Digi Cold Chain Solution's market.

The terms of the acquisition included an upfront cash payment together with future earn-out payments and a holdback amount. Cash of $1.7 million was paid at time of closing. The earn-out payments are scheduled to be paid after June 30, 2017 which is the end of the earn-out period. The cumulative amount of these earn-out payments will not exceed $2.3 million. A preliminary purchase price allocation, estimated acquisition costs and proforma financial information are not available due to the timing of the acquisition.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

This Annual Report on Form 10-K includes the certifications attached as Exhibits 31.1 and 31.2 of our Chief Executive Officer and Chief Financial Officer required by Rule 13a-14 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This Item 9A includes information concerning the controls and control evaluations referred to in those certifications.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act that are designed to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management of the Company, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the design and operation of our disclosure controls and procedures as of September 30, 2016. Based on their evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2016, our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d - 15(e) under the Security Exchange Act of 1934, as amended) were not effective because of the material weakness in internal control over financial reporting described below.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements for external purposes in accordance with generally accepted accounting principles. Management, with the participation of our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting as of September 30, 2016.

In making this assessment, management used the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework (2013). A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our interim or annual financial statements will not be prevented or detected on a timely basis.

We did not design effective controls to identify and maintain segregation of duties between the ability to create and post manual journal entries to the general ledger system for a key accounting individual as we moved locations at one of our subsidiaries, impacting the accuracy and completeness of all key accounts and disclosures at our German subsidiary. Specifically, the individual was assigned system access to both prepare and post journal entries, while holding responsibility for review of certain monthly account reconciliations, without his entries being subject to an independent review.

The material weakness resulting from this deficiency did not result in any adjustments to the consolidated financial statements for the fiscal year ended September 30, 2016. However, this deficiency could result in misstatements to all key accounts and disclosures at our German subsidiary that would result in a material misstatement to our consolidated financial statements that would not be prevented or detected on a timely basis. Because of this material weakness, management concluded that the Company did not maintain effective internal control over financial reporting as of September 30, 2016, based on criteria in Internal Control - Integrated Framework (2013) issued by COSO.

The effectiveness of our internal control over financial reporting as of September 30, 2016 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which appears in Item 8 of this Annual Report on Form 10-K.

Remediation Efforts on the Material Weakness in Internal Control Over Financial Reporting

We are in the process of improving our internal controls to remediate the material weakness that existed as of September 30, 2016, as described above in Management’s Report on Internal Control Over Financial Reporting. We removed access to create and post journal entries from the member of the accounting team with incompatible duties as of September 30, 2016. In

70

addition, a thorough review of all journal entries made by the individual revealed no irregularities or errors. Although this was an isolated case, we intend to enhance our access review controls for our financial system to include a review of all employee status changes. We are also reviewing our procedures around the completeness of journal entry review to ensure that all manual journal entries are subject to independent review. The actions we take are subject to ongoing review by senior members of management, as well as audit committee oversight. We expect to remediate the identified material weakness by the end of our second fiscal quarter of 2017.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting during the quarterly period ended September 30, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

[1] During fiscal 2016 and 2015, we recorded net tax benefits of $1.5 million and $0.8 million, respectively. We recorded a benefit of $0.7 million in the first quarter of fiscal 2016 resulting from the reinstatement of the research and development tax credit for calendar year 2015, reversal of income tax reserves due to the expiration of the statute of limitations from various U.S. and foreign tax jurisdictions and reversal of tax reserves due to the resolution of tax audits. In the third quarter of fiscal 2016, we recorded a tax benefit of $0.5 million primarily due to the filing of an amended income tax return resulting in a domestic refund related to qualified manufacturing activities. In the fourth quarter of fiscal 2016, we recorded a net tax benefit of $0.2 million, primarily due to the filing of an additional amended income tax return resulting in an additional domestic refund related to qualified manufacturing activities, partially offset by an adjustment of the state rate on net deferred tax assets.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Business Description

We are a leading provider of Internet of Things (IoT) networking hardware products and solutions. We provide Machine-to-Machine (M2M) and IoT connections to solve business and mission-critical machine communication challenges for our customers that are reliable, secure, scalable and managed. We create secure, easy to implement embedded solutions and services to help customers build IoT connectivity. In addition, we deploy ready to use, complete box solutions to connect remote machinery. We also manage cloud services, offer professional services and complete IoT solutions. Our solutions are deployed by a wide range of businesses and institutions. Any business that utilizes a significant number of devices, whose operations could benefit from remote monitoring or control, may realize benefits from IoT networking.

Discontinued Operations

On October 23, 2015, we sold all of the outstanding stock of our wholly owned subsidiary, Etherios Inc. (“Etherios”) to West Monroe Partners, LLC. Because the sale of Etherios represented a strategic shift that will have a major effect on our operations and financial results, we have classified our Etherios business as discontinued operations, which requires retrospective application to financial information for all periods presented. Since the cost of segregating the consolidated statement of cash flows outweighed the benefits, we elected not to segregate our consolidated statement of cash flows as the material items in the operating and investing sections are disclosed in Note 3 to our Consolidated Financial Statements.

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 on our consolidated balance sheets with unrealized gains and losses recorded in accumulated other comprehensive loss within stockholders’ equity. In order to estimate the fair value for each security in our investment portfolio, we obtain quoted market prices and trading activity for each security where available. We obtain relevant information from our investment advisor and, if warranted, also may review the financial solvency of certain security issuers.

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 (expense) income.

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

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

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 equipment are depreciated over a period of three to five years. Building improvements and buildings are depreciated over ten and thirty-nine years, respectively.

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. 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 included in cost of sales in the Consolidated Statements of Operations. Amortization of all other acquired identifiable intangible assets is charged to operating expenses 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. There were no material impairments identified in fiscal 2016, 2015 or 2014.

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.  The calculation of goodwill impairment requires us to make assumptions about the fair value of our one reporting unit, which historically has been approximated by using our market capitalization plus a control premium. Control premium assumptions require judgment and actual results may differ from assumed or estimated amounts.

Our test for potential goodwill impairment is a two-step approach. We estimate the fair value for our one reporting unit by comparing its fair value (market capitalization plus control premium) to our carrying value. If the carrying value of the reporting unit exceeds its estimated fair value, the second step of the goodwill impairment analysis requires us to measure the amount of the impairment loss. An impairment loss is calculated by comparing the implied fair value of the goodwill to its carrying amount. To calculate the implied fair value of goodwill, the fair value of the reporting unit's assets and liabilities, excluding goodwill, is estimated. The excess of the fair value of the reporting unit over the amount assigned to its assets and liabilities, excluding goodwill, is the implied fair value of the reporting unit's goodwill.

In June 2014, we performed a control premium study to determine the appropriate control premium to include in the calculation of fair value. We used 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, the following three methodologies were used: (1) analysis of individual transactions within our industry; (2) analysis of industry-wide data, and (3) analysis of global transaction data. Individual

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

transactions in the Communication Equipment or Technology Hardware, Storage and Peripherals industries were used to find transactions of target companies that operated in similar markets and shared similar operating characteristics with us. 

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

• Transactions announced between June 30, 2009 and the valuation date.

In analyzing industry-wide data, transactions in the following 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. The control premium analysis resulted in a range of control premium of 30% to 40%. We reviewed the data and concluded that a 35% control premium best represented the amount an investor would likely pay, over and above market capitalization, in order to obtain a controlling interest given the economic conditions at that time.

During the third quarter of fiscal 2016, we reviewed recent control premium data for transactions that occurred during fiscal 2016 in the industries previously described. The data indicated that our 35% control premium continued to be indicative of the amount that an investor would pay to obtain a controlling interest based on current macroeconomic and industry data.

At June 30, 2016, our market capitalization was $278.6 million compared to our carrying value of $294.9 million. Our market capitalization plus our estimated control premium of 35% resulted in a fair value in excess of our carrying value by a margin of 27%. We concluded that no impairment was indicated and we were not required to complete the second step of the goodwill impairment analysis. No goodwill impairment charges were recorded. During the fourth quarter of fiscal 2016, we assessed various qualitative factors to determine whether or not an additional goodwill impairment assessment was required as of September 30, 2016, and we concluded that no additional impairment assessment was required.

We continue to monitor our stock price on a daily basis. If the stock price remained below certain thresholds for a significant period of time, we would complete an interim impairment assessment. We also monitor other events or circumstances that could have a significant impact on our operations. If one of these events or circumstances were to occur, we would evaluate whether an interim goodwill impairment assessment should be completed.

If our stock price or control premium declines, the first step of our goodwill impairment analysis may fail. We have identified factors that could result in additional interim goodwill impairment testing. For example, we would perform the second step of the impairment testing if our stock price fell below certain thresholds for a significant period of time, or if our control premium significantly decreased. Events or circumstances may occur that could negatively impact our stock price, including changes in our anticipated revenues and profits and our ability to execute on our strategies. In addition, our control premium could decline due to changes in economic conditions in the technology industry or more generally in the financial markets. An impairment could have a material effect on our consolidated balance sheet and results of operations. We have had no goodwill impairment losses since the adoption of Accounting Standards Codification (ASC) 350, Intangibles-Goodwill and Others, in fiscal 2003.

Contingent Consideration

We measure our contingent consideration liabilities recognized in connection with business combinations at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy as defined in ASC 320 “Investments - Debt and Equity Securities”. We used a probability-weighted discounted cash flow approach as a valuation technique to determine the fair value of the contingent consideration on the acquisition date. At each subsequent reporting period, the fair value is remeasured with the change in fair value recognized in general and administrative expense and interest expense in our Condensed Consolidated Statements of Operations. Amounts, if any, paid to the seller in excess of the amount recorded on the acquisition date will be classified as cash flows used in operating activities. Payments to the seller not exceeding the acquisition-date fair value of the contingent consideration will be classified as cash flows used in financing activities.

In general, we warrant our hardware 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 hardware 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.

Revenue Recognition

We recognize revenue in accordance with authoritative guidance issued by FASB related to revenue recognition.

Hardware product revenue as a percentage of total revenue was 96.6%, 95.9% and 94.4% in fiscal 2016, 2015 and 2014, respectively. We recognize hardware 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.

Sales to authorized domestic and foreign 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 and distribution sales for the current period. Estimated reserves for future returns and price adjustments are charged against revenue in the same period as the corresponding revenue is recorded.

Service revenue as a percentage of total revenue represented 3.4%, 4.1% and 5.6% in fiscal 2016, 2015 and 2014, respectively. Our service revenue is derived primarily from our wireless design services and our Digi Cold Chain Solutions. We also have some service revenue that is derived from our Digi Device Cloud™, which is a platform-as-a-service (PaaS) offering in which customers pay for services consumed in terms of devices being managed and monitored, or as a monthly service fee for access to information.  In addition, we have small amounts of revenue from our support services. We recognize service revenue from our wireless design services, Digi Cold Chain Solutions and Device Cloud based upon performance, including final product delivery and customer acceptance.  In addition, we recognize small amounts of revenue from our support services which is recognized over the life of the contract, and training as the services are performed.

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.

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 functional currency. Assets and liabilities of these operations are translated at the exchange rates in effect at the end of each reporting period. For our larger international subsidiaries, statements of operations accounts are translated at the daily rate. For all other international subsidiaries, our 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 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 2016, 2015 and 2014, there were net transaction (losses) gains of $(0.7) million, $0.6 million and $0.5 million, respectively, that were recorded in other (expense) income, net. We manage our net asset or net liability position for U.S. dollar accounts in our foreign locations to reduce our foreign currency risk. We have not implemented a formal hedging strategy.

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 restricted stock units. 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.

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):

	Fiscal years ended September 30,
	2016		2015			2014
Numerator:
Income from continuing operations	$	13,478	$	9,433		$	4,493
Income (loss) from discontinued operations, after income taxes	$	3,230	$	(2,845	)	$	(2,742	)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Because their effect would be anti-dilutive at period end, certain potentially dilutive shares related to stock options to purchase common shares were excluded 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, 2016, 2015 and 2014, such excluded stock options were 1,519,691, 3,016,911 and 3,284,993, respectively.

Use of Estimates and Risks and Uncertainties

The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United 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 amount of revenue 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 loss account in stockholders’ equity.

Recent Accounting Developments

Adopted

In November 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” ASU 2015-17 simplified the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as non-current in the balance sheet. The amendments in this Update are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods and may be applied either prospectively to all deferred tax assets and liabilities or retrospectively to all periods presented. Early adoption is permitted. We elected to early adopt ASU 2015-17 beginning in the fiscal quarter ending December 31, 2015. Other than the revised balance sheet presentation of deferred tax assets and liabilities from current to non-current, the adoption of this standard did not have a material impact to our consolidated financial statements.

In September 2015, FASB issued ASU 2015-16, “Simplifying the Accounting for Measurement-Period Adjustments.” To simplify the accounting for adjustments made to provisional amounts recognized in a business combination, the amendments in this update eliminate the requirement to retrospectively account for those adjustments. The amendments in this update are effective for fiscal years beginning after December 15, 2015, including interim periods within those years, which for us will be the first fiscal quarter ending December 31, 2016. Earlier application is permitted for financial statements that have not been issued. We elected to early adopt ASU 2015-16 beginning the fiscal quarter ending December 31, 2015. The adoption of this standard did not have a material impact to our consolidated financial statements.

Not Yet Adopted

In August 2016, FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments.” The amendments in this update provided guidance on eight specific cash flow issues. This update is to provide specific guidance on each of the eight issues, thereby reducing the diversity in practice in how certain transaction are classified in the statement of cash flows. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2017, which for us is the first quarter ended December 31, 2018. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2016-15 on our consolidated financial statements.

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments.” The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses. This update is intended to provide financial statement users with more decision-useful information about the expected credit losses. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2019, which for us is

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

the first quarter ended December 31, 2020. Entities may early adopt beginning after December 15, 2018. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements.

In March 2016, FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting.” This update includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2016, which for us is the first fiscal quarter ending December 31, 2017. Early adoption is permitted. We will adopt ASU 2016-09 beginning October 1, 2017. We are currently evaluating the impact of the adoption of ASU 2016-09 on our consolidated financial statements. Prospectively, beginning October 1, 2017, excess tax benefits and tax deficiencies will be reflected as income tax benefit or expense in our Consolidated Statement of Operations and could result in a material impact. The extent of the excess tax benefits or tax deficiencies are subject to variation in our stock price and the timing of RSU vestings and employee stock option exercises.

In February, 2016, FASB issued ASU 2016-02, “Leases (Topic 842)”, which amends the existing guidance to require lessees to recognize lease assets and lease liabilities from operating leases on the balance sheet. This ASU is effective using the modified retrospective approach for annual periods and interim periods within those annual periods beginning after December 15, 2018, which for us is the first fiscal quarter ending December 31, 2019. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2016-02 on our consolidated financial statements.

In January 2016, FASB issued ASU 2016-01, “Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 will require equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. The amendments in this update will also simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, eliminate the requirement for public business entities to disclose the method and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet and require these entities to use the exit price notion when measuring fair value of financial instruments for disclosure purposes. This ASU would also change the presentation and disclosure requirements for financial instruments. In addition, this ASU clarifies the guidance related to valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, which for us is the first fiscal quarter ending December 31, 2018. Early adoption is permitted for financial statements of fiscal years and interim periods that have not been issued. We are currently evaluating the impact of the adoption of ASU 2016-01.

In July 2015, FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” This provision would require inventory that was previously recorded using first-in, first-out (“FIFO”) to be recorded at lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This guidance is effective for fiscal years beginning after December 15, 2016 and interim periods within those years, which for us will be the first fiscal quarter ending December 31, 2017. The amendments in this guidance should be applied prospectively with earlier application permitted as of the beginning of an interim or annual period. We are currently evaluating the impact of the adoption of ASU 2015-11 and whether it would have a material impact on our consolidated financial statements.

In April 2015, FASB issued ASU 2015-05, “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” The new standard provides guidance to customers about whether a cloud computing arrangement includes a software license. If the arrangement does include a software license, the software license element of the arrangement should be accounted for in the same manner as the acquisition of other software licenses. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, with early adoption permitted. We expect to adopt this guidance beginning with our fiscal quarter ending December 31, 2016. We do not expect this guidance to have a material impact on our consolidated financial statements.

In August 2014, FASB issued ASU 2014-15, “Presentation of Financial Statements - Going Concern.” This guidance requires management to evaluate whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. These amendments are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter, which for us, will be our annual period ended September 30, 2017. Early adoption is permitted. While we are evaluating the impact of the adoption of ASU 2014-15, we do not expect it to have an impact on our consolidated financial statements.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

In May 2014, FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” This guidance provides a five-step analysis in determining when and how revenue is recognized so that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods and services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued ASU 2015-14 “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date” which approved a one-year deferral of the effective date of ASU 2014-09. As a result of this deferral, ASU 2014-09 is effective for our fiscal 2019, including interim periods within that reporting period. The FASB also agreed to allow us to choose to adopt the standard effective for our fiscal 2018. In addition, the FASB issued ASU 2016-08, ASU 2016-10 and ASU 2016-12 in March 2016, April 2016 and May 2016, respectively, to provide interpretive clarifications on the new guidance in ASC Topic 606. We are currently working through an adoption plan and have identified our revenue streams and completed a preliminary analysis of how we currently account for revenue transactions compared to the revenue accounting required under the new standard.  We intend to complete our adoption plan in fiscal 2017.  This plan includes a review of transactions supporting each revenue stream to determine the impact of accounting treatment under ASC 606, evaluation of the method of adoption, and completing a rollout plan for implementation of the new standard with affected functions in our organization.  Because of the nature of the work that remains, at this time we are unable to reasonably estimate the impact of adoption on our consolidated financial statements.  We plan to adopt the new guidance beginning October 1, 2018.

Acquisition

Business Combinations [Abstract]

ACQUISITION

ACQUISITION

Acquisition of Bluenica Corporation

On October 5, 2015 we purchased all of the outstanding stock of Bluenica Corporation (“Bluenica”), a company focused on temperature monitoring of perishable goods in the food industry by using wireless sensors which are installed in grocery and convenience stores, restaurants, and in products during shipment and storage to ensure that quality, freshness and public health requirements are met.  This acquisition forms the basis for our Digi Cold Chain Solutions.

The terms of the acquisition included an upfront cash payment together with earn-out payments.  Cash of $2.9 million was paid at time of closing.  The earn-out payments are scheduled to be paid in installments over a four-year period based on revenue achievement of the acquired business. Each of the earn-out payments will be calculated based on the revenue performance of Digi Cold Chain Solutions for each respective earn-out period. The cumulative amount of these earn-out payments will not exceed $11.6 million.  An additional payment, not to exceed $3.5 million, may also be due depending on revenue performance. The fair value of this contingent consideration was $10.4 million at the date of acquisition (see Note 8 to the Consolidated Financial Statements). We have determined that the earn-out will be considered as part of the purchase price consideration as there are no continuing employment requirements associated with the earn-out. Costs directly related to the acquisition, including legal, accounting and valuation fees, of approximately $0.1 million have been charged directly to operations and are included in general and administrative expense in our Condensed Consolidated Statements of Operations in fiscal 2016.

The purchase price was allocated to the estimated fair value of assets acquired and liabilities assumed. The purchase price allocation resulted in the recognition of $11.0 million of goodwill. We believe that the acquisition resulted in the recognition of goodwill because this is a complementary acquisition for us and will provide a source of recurring revenue in a new vertical market.

Operating results for Bluenica, now known as Digi Cold Chain Solutions, are included in our Consolidated Statements of Operations from October 6, 2015. The Consolidated Balance Sheet as of September 30, 2016 reflects the final allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition.

The Bluenica acquisition has been accounted for using the acquisition method of accounting, which requires, among other things, that assets acquired and liabilities assumed pursuant to the stock purchase agreement be recognized at fair value as of the acquisition date. During the third quarter of fiscal 2016, we finalized the purchase price allocation by recording adjustments to our deferred tax liabilities account as a result of the completion and filing of the last annual tax return for Bluenica.

2. ACQUISITION (CONTINUED)

The following table summarizes the values of Bluenica assets acquired and liabilities assumed as of the acquisition date (in thousands):

Cash	$	2,888
Purchase price payable upon completion of diligence matters	115
Fair value of contingent consideration on acquired business	10,400
Total purchase price consideration	$	13,403
Fair value of net tangible assets acquired	$	129
Fair value of identifiable intangible assets acquired:
Purchased and core technology	2,000
Customer relationships	900
Goodwill	10,985
Deferred tax liabilities, net	(611		)
Total	$	13,403

The weighted average useful life for all the identifiable intangibles listed above is 5.6 years. For purposes of determining fair value, the purchased and core technology identified above is assumed to have a useful life of five years and the customer relationships are assumed to have useful lives of seven years. 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.

The following unaudited pro forma condensed consolidated results of operations for fiscal 2015 have been prepared as if the acquisition of Bluenica had occurred at the beginning of fiscal 2015. Pro forma adjustments include amortization of identifiable intangible assets.

Net income (1)	$	0.22

(1) Earnings per share presented are calculated by line item and may not add due to the use of rounded amounts.

Since the acquisition of Bluenica occurred close to the beginning of our fiscal 2016, we believe that the proforma amounts would be not be materially different from actual amounts. Revenue for fiscal 2016 related to the Bluenica acquisition was $0.7 million. As our operating costs related to the Bluenica acquisition are now integrated, operating income and related earnings per share for Bluenica are not determinable for fiscal 2016.

Discontinued Operations

DISCONTINUED OPERATIONS

On October 23, 2015, we sold all the outstanding stock of our wholly owned subsidiary, Etherios to West Monroe Partners, LLC. We sold Etherios as part of a strategy to focus on providing highly reliable machine connectivity solutions for business and mission-critical application environments. Etherios was included in our single operating segment.

Below is a summary of the gain on sale (in thousands):

Gross proceeds	$	4,096

Employee related liabilities	(1,134		)
Working capital adjustment	(113		)
Net cash proceeds	2,849
Present value of receivable due on October 23, 2016	2,941

Net assets of Etherios	(3,383		)
Facility abandonment costs	(725		)
Transaction costs, primarily professional fees	(734		)
Gain on sale of discontinued operations, before income taxes	$	2,870

The terms of the sale agreement provide that West Monroe Partners LLC will pay us $3.0 million on October 23, 2016 and $2.0 million on October 23, 2017. The present value of these amounts is included within the total fair value of consideration received. These receivable amounts are unsecured and non-interest bearing. The carrying value of these receivables presented on our Consolidated Balance Sheet at September 30, 2016 approximated their fair values, which were determined using level 3 cash flow fair value measurement techniques. We received the first payment of $3.0 million on October 21, 2016.

Goodwill has been included in the net assets of Etherios based on the relative fair value of Etherios compared to the fair value of the Company, as the Company consists of a single reporting unit for goodwill impairment testing purposes.

As a condition to the sale agreement, we retained the operating leases in the Dallas and Chicago locations. Digi is no longer using these facilities and has sublet the Dallas location to West Monroe Partners, LLC through December 31, 2017. Also in connection with the sale, we assigned our San Francisco lease to West Monroe Partners, LLC. A remaining potential obligation exists in the event of a default under the assigned lease. However, we believe the likelihood of a liability related to this lease is remote. As of September 30, 2016, the future minimum lease payments for the San Francisco lease are approximately $0.1 million.

Income (loss) from discontinued operations, after income taxes, as presented in the Consolidated Statements of Operations for the twelve months ended September 30, 2016, 2015 and 2014 is as follows (in thousands):

3. DISCONTINUED OPERATIONS (CONTINUED)

Income tax benefit on discontinued operations for the twelve months ended September 30, 2016 was $0.5 million and primarily represented income tax benefits for deductible transaction costs, partially offset by a tax expense for equity awards for which we will not receive a tax deduction. For tax purposes, this transaction resulted in a capital loss of $13.7 million, as the tax basis of the Etherios stock was higher than the book basis of the assets that were sold. Since we do not expect to be able to utilize this capital loss in the five year carryforward period, a deferred tax asset offset by a full valuation allowance of $5.1 million was recorded in the third quarter of fiscal 2016 upon completion of the capital loss calculation.

At September 30, 2015, the carrying amounts of major classes of assets and liabilities of discontinued operations included in the Consolidated Balance Sheet was as follows (in thousands):

	September 30, 2015
Current assets:
Accounts receivable, net	$	1,417
Deferred tax assets	127
Other current assets	80

Total liabilities of discontinued operations	$	1,576

(1) As of September 30, 2015, we had a consolidated net deferred income tax asset related to the United States federal jurisdiction. That net deferred income tax asset position included a deferred income tax liability of $589 thousand related to Etherios which was entirely in the United States federal tax jurisdiction.

Segment Reporting [Abstract]

SEGMENT INFORMATION AND MAJOR CUSTOMERS

SEGMENT INFORMATION AND MAJOR CUSTOMERS

We operate under a single operating and reporting segment.  Our revenue consists of hardware product revenue and service revenue. In an effort to provide further transparency of our financial information, beginning the first quarter of fiscal 2016, we transitioned away from reporting revenue in terms of growth and mature hardware products and now report four product categories: Cellular routers and gateways, Radio Frequency (RF), Embedded and Network. We believe this is a more meaningful presentation and reflects how we are monitoring our revenue.

Our cellular product category includes cellular routers and all gateways, and the RF product category includes XBee^® modules as well as other RF solutions. The embedded product category includes Digi Connect^® and Rabbit^® embedded systems on

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, we obtain quoted market prices and trading activity for each security where available. We obtain relevant information from our investment advisor and, if warranted, also may review the financial solvency of certain security issuers. As of September 30, 2016, 18 of our 48 securities that we held 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 current marketable securities are scheduled to mature in less than one year and our non-current marketable securities are scheduled to mature in less than two years. We received proceeds from the sale of our available-for-sale marketable securities of $73.7 million, $38.0 million and $47.4 million for fiscal 2016, 2015 and 2014, respectively.

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 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 and to financial liabilities for contingent consideration. 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 and liabilities that are measured at fair value on a recurring basis (in thousands):

			Fair Value Measurements at September 30, 2016 using:
	Total carrying value at September 30, 2016		Quoted price in active markets (Level 1)		Significant other observable inputs (Level 2)		Significant unobservable inputs (Level 3)

8. FAIR VALUE MEASUREMENTS (CONTINUED)

			Fair Value Measurements at September 30, 2015 using:
	Total carrying value at September 30, 2015		Quoted price in active markets (Level 1)		Significant other observable inputs (Level 2)		Significant unobservable inputs (Level 3)
Assets:
Money market	$	14,436	$	14,436	$	—	$	—
Corporate bonds	35,840		—		35,840		—

Government municipal bonds	3,224		—		3,224		—
Total assets measured at fair value	$	75,253	$	14,436	$	60,817	$	—

Our money market funds, which have been determined to be 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 into or out of our Level 2 financial assets during the twelve months ended September 30, 2016.

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 or contingent consideration, currently and in the future. If market conditions deteriorate, we may incur impairment charges for securities in our investment portfolio. We may also incur changes to our contingent consideration liability as discussed below.

In connection with the Bluenica acquisition discussed in Note 2, we are required to make contingent payments over a period of up to four years, subject to Digi Cold Chain Solutions achieving specified revenue thresholds. The fair value of the liability for contingent payments recognized upon acquisition was $10.4 million, and was estimated by discounting to present value the probability-weighted contingent payments expected to be made. Assumptions used in this calculation included the discount rate and various probability factors. This liability is considered to be a Level 3 financial liability that is re-measured each reporting period.

The following table presents a reconciliation of the liability measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the twelve months ended September 30, 2016 (in thousands):

	Twelve months ended September 30, 2016
Fair value at beginning of period	$	—
Purchase price contingent consideration	10,400
Change in fair value of contingent consideration	(440		)
Fair value at end of period	$	9,960

The change in fair value of contingent consideration for the acquisition of Bluenica is included in general and administrative and interest expense on our Condensed Consolidated Statements of Operations and reflects our estimate of the probability of achieving the relevant targets and is discounted based on our estimated discount rate. We have estimated the fair value of the contingent consideration based on the probability of achieving the specified revenue thresholds at 75.8% to 98.0%. A significant increase (decrease) in our estimates of achieving the relevant targets could materially increase (decrease) the fair value of the contingent consideration liability.

2016 Restructuring

On January 19, 2016, we approved a restructuring plan for our wireless design services group. This plan resulted in an elimination of 5 positions. We recorded a restructuring charge of $0.1 million related to severance during the second quarter of fiscal 2016 and paid the majority of the severance during that same quarter.

On November 19, 2015, we approved a restructuring plan impacting our corporate staff. The plan closed our Dortmund, Germany office and relocated certain employees to our Munich office. We also recorded a contract termination charge as we relocated employees in our Minneapolis, Minnesota office to our World Headquarters in Minnetonka, Minnesota in December 2015. We recorded a restructuring charge of $0.7 million that included $0.5 million of severance and $0.2 million of contract termination costs during the first quarter of fiscal 2016. This restructuring resulted in an elimination of 10 positions. The payments associated with these charges were completed in the third quarter of fiscal 2016.

2015 Restructuring

On January 22, 2015, we announced the closure of our India location. The March closure resulted in the elimination of approximately 38 employees from engineering, sales and administration. We recorded a restructuring charge of $0.4 million related to severance during the second quarter of fiscal 2015. The payments associated with this charge were completed during the third quarter of fiscal 2015.

2014 Restructuring

On October 31, 2013, we announced our intention to restructure certain of our operations in India. The restructuring was primarily associated with cost reduction initiatives resulting in the elimination of approximately 40 engineering and sales positions in our work force. We recorded a restructuring charge of $0.2 million related to severance during the first quarter of fiscal 2014. The payments associated with these charges and all the actions associated with the restructuring were completed during the third quarter of fiscal 2014.

2013 Restructuring

On September 27, 2013, we announced our intention to restructure certain of our operations in the U.S. The restructuring was primarily associated with cost reduction initiatives and resulted in the elimination of 15 positions in our work force. We recorded a restructuring charge of $0.4 million for severance during the fourth quarter of fiscal 2013.

Net deferred tax asset	$	6,679		$	9,336

As of September 30, 2016, we have estimated carryforwards for tax purposes as follows: We have $0.9 million of carryforwards mostly related to state research and development tax credits and carryforwards consisting of a U.S. capital loss of $5.1 million and non-U.S. net operating losses of $0.3 million. The majority of the state research and development tax credits and non-U.S. net operating losses have an unlimited carryforward period. Our non-U.S. tax credit carryforwards will expire in 2028. Our U.S. capital loss carryforward will expire in 2020.

Our valuation allowance for certain U.S. and foreign locations increased to $6.0 million at September 30, 2016 from $0.9 million at September 30, 2015, primarily due to the capital loss realized on the sale of Etherios. We are not expecting to generate sufficient capital gains within the carryforward period to fully utilize the capital loss. The amount of the deferred tax assets 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.

During fiscal 2016, we recorded net tax benefits of $1.5 million, primarily from the reinstatement of the federal research and development tax credit for calendar year 2015 and the reversal of tax reserves due to the expiration of statutes of limitation from U.S. and foreign tax jurisdictions. In addition, we filed amended income tax returns resulting in an additional domestic refund related to qualified manufacturing activities. These benefits are included within the discrete tax benefits in the above table.

During fiscal 2015, we recorded net tax benefits of $0.8 million, resulting from the reinstatement of the research and development tax credit for calendar year 2014, reversal of tax reserves due to the expiration of statute of limitations from U.S. and foreign tax jurisdictions and reversal of tax reserves due to the resolution of tax audits. These benefits are included within the discrete tax benefits in the above table.

During fiscal 2014, we recorded net tax benefits of $1.5 million related to the re-measurement and reversal of certain income tax reserves as a result of a federal income tax audit of fiscal 2012, the reassessment of state research and development tax credits and the release of income tax reserves due to the expiration of statute of limitations from U.S. and foreign tax jurisdictions.

The total amount of unrecognized tax benefits at September 30, 2016 that, if recognized, would affect our effective tax rate is $1.6 million. We expect that it is reasonably possible that the total amounts of unrecognized tax benefits will decrease approximately $0.7 million over the next 12 months due to the expiration of various statutes of limitations.

Of the $1.7 million of unrecognized tax benefits, $1.3 million is included in non-current income taxes payable and $0.4 million is included with non-current deferred tax assets on the consolidated balance sheet at September 30, 2016.

We recognize interest and penalties related to income tax matters in income tax expense. During fiscal 2016 and 2015, 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 of $0.2 million at September 30, 2016 and $0.3 million at September 30, 2015. These accrued interest and penalties are included in our non-current income taxes payable on our consolidated balance sheets.

We operate in multiple tax jurisdictions both in the U.S. and outside of the U.S and face audits from various tax authorities regarding transfer pricing, tax credits, and other matters. 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. With a few exceptions, we are no longer subject to income tax examination for tax years prior to fiscal 2013. For state tax authorities, most notably in California and Texas, generally we are no longer subject to income tax examination for tax years before fiscal 2012, and for Minnesota for tax years prior to fiscal 2014. We do not anticipate significant changes to our unrecognized tax benefits as a result of these examinations.

11. INCOME TAXES (CONTINUED)

At September 30, 2016, we had approximately $31.5 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 or intention to repatriate historical earnings in the form of cash to the United States, if we change our assertion from indefinitely reinvesting undistributed foreign earnings, 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 up to $0.6 million.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION

During fiscal 2016, stock-based awards were granted under our 2016 Omnibus Incentive Plan (the “2016 Plan”), as well as our 2014 Omnibus Incentive Plan (the “2014 Plan”). Grants under the 2014 Plan ceased upon stockholder approval of the 2016 Plan during the second quarter of fiscal 2016. The authority to grant options under the 2016 Plan and set other terms and conditions rests with the Compensation Committee of the Board of Directors. We also have awards outstanding under our 2013 Omnibus Incentive Plan (the “2013 Plan”), 2000 Omnibus Stock Plan, as amended and restated as of December 4, 2009 (the “2000 Plan”), and the Stock Option Plan, as amended and restated as of November 27, 2006 (the “Stock Option Plan”) and our Non-Officer Stock Option Plan as amended and restated as of November 27, 2006 (the “Non-Officer Plan”).

The 2016 Plan initially authorized the issuance of up to 1,500,000 common shares in connection with awards of stock options, stock appreciation rights, restricted stock, restricted stock units, performance-based full value awards or other stock-based awards. Eligible participants include our employees, our affiliates, non-employee directors of our Company and any consultant or advisor who is a natural person and provides services to us or our affiliates. Options that have been granted under the 2016 Plan typically vest over a four-year period and will expire if unexercised after seven years from the date of grant. Restricted stock unit awards (“RSUs”) that have been granted to directors typically vest in one year. RSUs that have been granted to executives and employees typically vest in November over a four-year period. Awards may be granted under the 2016 Plan until January 31, 2026. Options under the 2016 Plan can be granted as either incentive stock options (“ISOs”) or non-statutory stock options (“NSOs”). The exercise price of options and the grant date price of restricted stock is determined by our Compensation Committee but may not be less than the fair market value of our common stock based on the closing price on the date of grant. Upon exercise, we issue new shares of stock. As of September 30, 2016, there were approximately 1,450,982 shares available for future grants under the 2016 Plan.

The 2014 Plan initially authorized the issuance of up to 2,250,000 common shares in connection with awards of stock options, stock appreciation rights, restricted stock, restricted stock units, performance-based full value awards or other stock-based awards. Eligible participants included our employees, our affiliates, non-employee directors of our Company and any consultant or advisor who is a natural person and provides services to us or our affiliates. Options granted under this plan generally vested over a four year service period and expired if unexercised after eight years from the date of grant. Restricted stock awards (RSU's) that were granted to Directors typically vested in one year. RSU's that were granted to executives and employees typically vested in November over a four-year period. Options under the 2014 Plan were granted as either incentive stock options (ISOs) or non-statutory stock options (NSOs). Awards may no longer be granted under the 2014 Plan as the plan was terminated effective February 1, 2016 at the Annual Meeting of Stockholders. The exercise price of options and the grant date price of restricted stock was determined by our Compensation Committee but could not be less than the fair market value of our common stock based on the closing price on the date of grant.

The 2013 Plan initially authorized the issuance of up to 1,750,000 common shares in connection with awards of stock options, stock appreciation rights, restricted stock, restricted stock units, performance-based full value awards or stock awards. Eligible participants included our employees, non-employee directors, consultants and advisors. Options granted under this plan generally vested over a four year service period and expired if unexercised after eight years from the date of grant. RSU's that were granted to Directors typically vested in one year. Awards may no longer be granted under the Incentive Plan as the plan was terminated effective January 27, 2014 at the Annual Meeting of Stockholders. Options under the 2013 Plan were granted as either ISOs or NSOs. The exercise price was determined by our Compensation Committee but could not be less than the fair market value of our common stock based on the closing price on the date of grant.

The 2000 Plan initially authorized 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 included our employees, non-employee directors, consultants and advisors. An authorization to issue an additional 2,500,000 common shares was ratified on January 25, 2010 at the Annual Meeting of Stockholders. Awards may no longer be granted under the 2000 Plan as

12. STOCK-BASED COMPENSATION (CONTINUED)

the plan was terminated as to future awards on January 28, 2013 at the Annual Meeting of Stockholders. Options under the 2000 Plan were granted as either ISOs or non-statutory stock options NSOs. The exercise price was determined by our Compensation Committee but could not be less than the fair market value of our common stock based on the closing price on the date of grant.

Awards outstanding under the Stock Option Plan and the Non-Officer Plan included NSOs. In addition, the Stock Option Plan also included ISOs to employees and others who provided services to us, including consultants, advisers and directors. Options granted under these plans generally vested over a four year service period and will expire if unexercised after ten years from the date of grant. 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.

Our equity plans and corresponding forms of award agreements generally have provisions allowing employees to elect to satisfy tax withholding obligations through the delivery of shares, having us retain a portion of shares issuable under the award or paying cash to us for the withholding. During fiscal 2016 and 2015, our employees forfeited 47,464 shares and 9,371 shares, respectively in order to satisfy $0.6 million and $0.1 million, respectively, of withholding tax obligations related to stock-based compensation, pursuant to terms of awards under our board and shareholder-approved compensation plans. No shares were forfeited to satisfy withholding obligations during fiscal 2014.

We recorded cash received from the exercise of stock options of $7.2 million, $6.6 million and $3.7 million during fiscal years 2016, 2015 and 2014, respectively. During fiscal 2016, there were $0.2 million of excess tax benefits from stock-based compensation. The were no excess tax benefits from stock-based compensation during fiscal 2015 and excess tax benefits were minimal during fiscal year 2014.

We sponsor an Employee Stock Purchase Plan, as amended and restated as of October 29, 2013, 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 most recent amendments to the Purchase Plan, ratified by our stockholders on January 27, 2014, increased the total number of shares to 2,800,000 that may be purchased under the plan. Employee contributions to the Purchase Plan were $0.9 million in both fiscal 2016 and 2015, and $1.0 million in fiscal 2014. Pursuant to the Purchase Plan, 103,915, 123,847, and 129,449 shares of common stock were issued to employees during fiscal 2016, 2015 and 2014, respectively. Shares are issued under the Purchase Plan from treasury stock. As of September 30, 2016, 513,616 shares of common stock were available for future issuances under the Purchase Plan.

Stock-based compensation cost capitalized as part of inventory was immaterial as of September 30, 2016, 2015 and 2014.

Stock-based compensation expense is included in the consolidated results of operations as follows (in thousands):

The following table summarizes our stock option activity (in thousands, except per common share amounts):

	Options Outstanding		Weighted Average Exercised Price	Weighted Average Contractual Term (in years)	Aggregate Intrinsic Value (1)
Balance at September 30, 2015	4,800		$10.21
Granted	553		11.46
Exercised	(772	)	9.65
Forfeited / Canceled	(618	)	11.06
Balance at September 30, 2016	3,963		$10.36	4.5	$	6,078
Exercisable at September 30, 2016	2,857		$10.49	3.7	$	4,158

(1) The aggregate intrinsic value represents the total pre-tax intrinsic value, based on our closing stock price of $11.40 as of September 30, 2016, 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, 2016, 2015 and 2014 was $1.9 million, $0.9 million and $0.5 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:

	Fiscal years ended September 30,
	2016		2015		2014
Weighted average per option grant date fair value	$	3.90	$	2.98	$	4.35
Assumptions used for option grants:
Risk free interest rate	1.22% - 1.85%		1.57% - 1.85%		1.76% - 2.02%
Expected term	6.00 years		6.00 years		6.00 years
Expected volatility	32% - 33%		32% - 36%		38% - 40%
Weighted average volatility	32%		35%		40%
Expected dividend yield	0		0		0

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 our stock. We use historical data to estimate option exercise and employee termination information within the valuation model. 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.

We use historical data to estimate pre-vesting forfeiture rates. The pre-vesting forfeiture rate used in fiscal 2016 was 10.0%. As of September 30, 2016, the total unrecognized compensation cost related to non-vested stock-based compensation arrangements, net of expected forfeitures, was $2.9 million and the related weighted average period over which it is expected to be recognized was approximately 3.0 years.

$7.40 - $15.23	3,963	4.53	$	10.36	2,857	$	10.49

The total grant date fair value of shares vested was $2.9 million in both fiscal 2016 and 2015 and $0.8 million in fiscal 2014.

A summary of our non-vested restricted stock units as of September 30, 2016 and changes during the twelve months then ended is presented below (in thousands, except per common share amounts):

	Number of Awards		Weighted Average Grant Date Fair Value
Nonvested at September 30, 2015	543		$	8.41

Nonvested at September 30, 2016	505		$	9.67

As of September 30, 2016, the total unrecognized compensation cost related to non-vested restricted stock units was $3.0 million and the related weighted average period over which it is expected to be recognized was approximately 1.3 years.

In the third quarter of fiscal 2016, we recorded a tax benefit of $0.5 million primarily due to the filing of an amended income tax return resulting in a domestic refund related to qualified manufacturing activities. In the fourth quarter of fiscal 2016, we recorded a net tax benefit of $0.2 million, primarily due to the filing of an additional amended income tax return resulting in an additional domestic refund related to qualified manufacturing activities, partially offset by an adjustment of the state rate on net deferred tax assets. We recorded net tax benefits of $0.5 million in the first quarter of fiscal 2015 resulting from the reinstatement of the research and development tax credit for calendar year 2014, reversal of income tax reserves due to the expiration of the statute of limitations from various U.S. and foreign tax jurisdictions and reversal of tax reserves due to the resolution of tax audits. In the third quarter of fiscal 2015, we recorded a tax benefit of $0.4 million primarily due to the reversal of reserves for state research and development tax credits and transfer pricing, partially offset by an adjustment of the state rate on net deferred tax assets.

Acquisition of FreshTemp, LLC

On November 1, 2016, we purchased all of the outstanding stock of FreshTemp, LLC, a Pittsburgh-based provider of temperature monitoring and task management solutions for the food industry. We believe this is a complementary acquisition for us as the acquired technology will continue to be supported to create an advanced portfolio of products for the Digi Cold Chain Solution's market.

The terms of the acquisition included an upfront cash payment together with future earn-out payments and a holdback amount. Cash of $1.7 million was paid at time of closing. The earn-out payments are scheduled to be paid after June 30, 2017 which is the end of the earn-out period. The cumulative amount of these earn-out payments will not exceed $2.3 million. A preliminary purchase price allocation, estimated acquisition costs and proforma financial information are not available due to the timing of the acquisition.

Accounting Policies [Abstract]

Discontinued Operations

Discontinued Operations

On October 23, 2015, we sold all of the outstanding stock of our wholly owned subsidiary, Etherios Inc. (“Etherios”) to West Monroe Partners, LLC. Because the sale of Etherios represented a strategic shift that will have a major effect on our operations and financial results, we have classified our Etherios business as discontinued operations, which requires retrospective application to financial information for all periods presented. Since the cost of segregating the consolidated statement of cash flows outweighed the benefits, we elected not to segregate our consolidated statement of cash flows as the material items in the operating and investing sections are disclosed in Note 3 to our Consolidated Financial Statements.

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 on our consolidated balance sheets with unrealized gains and losses recorded in accumulated other comprehensive loss within stockholders’ equity. In order to estimate the fair value for each security in our investment portfolio, we obtain quoted market prices and trading activity for each security where available. We obtain relevant information from our investment advisor and, if warranted, also may review the financial solvency of certain security issuers.

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 (expense) income.

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

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

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 equipment are depreciated over a period of three to five years. Building improvements and buildings are depreciated over ten and thirty-nine years, respectively.

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. 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 included in cost of sales in the Consolidated Statements of Operations. Amortization of all other acquired identifiable intangible assets is charged to operating expenses 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.

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.  The calculation of goodwill impairment requires us to make assumptions about the fair value of our one reporting unit, which historically has been approximated by using our market capitalization plus a control premium. Control premium assumptions require judgment and actual results may differ from assumed or estimated amounts.

Contingent Consideration

Contingent Consideration

We measure our contingent consideration liabilities recognized in connection with business combinations at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy as defined in ASC 320 “Investments - Debt and Equity Securities”. We used a probability-weighted discounted cash flow approach as a valuation technique to determine the fair value of the contingent consideration on the acquisition date. At each subsequent reporting period, the fair value is remeasured with the change in fair value recognized in general and administrative expense and interest expense in our Condensed Consolidated Statements of Operations. Amounts, if any, paid to the seller in excess of the amount recorded on the acquisition date will be classified as cash flows used in operating activities. Payments to the seller not exceeding the acquisition-date fair value of the contingent consideration will be classified as cash flows used in financing activities.

Warranties

Warranties

In general, we warrant our hardware 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 hardware 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.

Revenue Recognition

Revenue Recognition

We recognize revenue in accordance with authoritative guidance issued by FASB related to revenue recognition.

Hardware product revenue as a percentage of total revenue was 96.6%, 95.9% and 94.4% in fiscal 2016, 2015 and 2014, respectively. We recognize hardware 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.

Sales to authorized domestic and foreign 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 and distribution sales for the current period. Estimated reserves for future returns and price adjustments are charged against revenue in the same period as the corresponding revenue is recorded.

Service revenue as a percentage of total revenue represented 3.4%, 4.1% and 5.6% in fiscal 2016, 2015 and 2014, respectively. Our service revenue is derived primarily from our wireless design services and our Digi Cold Chain Solutions. We also have some service revenue that is derived from our Digi Device Cloud™, which is a platform-as-a-service (PaaS) offering in which customers pay for services consumed in terms of devices being managed and monitored, or as a monthly service fee for access to information.  In addition, we have small amounts of revenue from our support services. We recognize service revenue from our wireless design services, Digi Cold Chain Solutions and Device Cloud based upon performance, including final product delivery and customer acceptance.  In addition, we recognize small amounts of revenue from our support services which is recognized over the life of the contract, and training as the services are performed.

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.

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 functional currency. Assets and liabilities of these operations are translated at the exchange rates in effect at the end of each reporting period. For our larger international subsidiaries, statements of operations accounts are translated at the daily rate. For all other international subsidiaries, our 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 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 2016, 2015 and 2014, there were net transaction (losses) gains of $(0.7) million, $0.6 million and $0.5 million, respectively, that were recorded in other (expense) income, net. We manage our net asset or net liability position for U.S. dollar accounts in our foreign locations to reduce our foreign currency risk. We have not implemented a formal hedging strategy.

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 restricted stock units. 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.

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 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 amount of revenue 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 loss account in stockholders’ equity.

Recent Accounting Developments

Recent Accounting Developments

Adopted

In November 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” ASU 2015-17 simplified the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as non-current in the balance sheet. The amendments in this Update are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods and may be applied either prospectively to all deferred tax assets and liabilities or retrospectively to all periods presented. Early adoption is permitted. We elected to early adopt ASU 2015-17 beginning in the fiscal quarter ending December 31, 2015. Other than the revised balance sheet presentation of deferred tax assets and liabilities from current to non-current, the adoption of this standard did not have a material impact to our consolidated financial statements.

In September 2015, FASB issued ASU 2015-16, “Simplifying the Accounting for Measurement-Period Adjustments.” To simplify the accounting for adjustments made to provisional amounts recognized in a business combination, the amendments in this update eliminate the requirement to retrospectively account for those adjustments. The amendments in this update are effective for fiscal years beginning after December 15, 2015, including interim periods within those years, which for us will be the first fiscal quarter ending December 31, 2016. Earlier application is permitted for financial statements that have not been issued. We elected to early adopt ASU 2015-16 beginning the fiscal quarter ending December 31, 2015. The adoption of this standard did not have a material impact to our consolidated financial statements.

Not Yet Adopted

In August 2016, FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments.” The amendments in this update provided guidance on eight specific cash flow issues. This update is to provide specific guidance on each of the eight issues, thereby reducing the diversity in practice in how certain transaction are classified in the statement of cash flows. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2017, which for us is the first quarter ended December 31, 2018. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2016-15 on our consolidated financial statements.

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments.” The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses. This update is intended to provide financial statement users with more decision-useful information about the expected credit losses. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2019, which for us is

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

the first quarter ended December 31, 2020. Entities may early adopt beginning after December 15, 2018. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements.

In March 2016, FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting.” This update includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2016, which for us is the first fiscal quarter ending December 31, 2017. Early adoption is permitted. We will adopt ASU 2016-09 beginning October 1, 2017. We are currently evaluating the impact of the adoption of ASU 2016-09 on our consolidated financial statements. Prospectively, beginning October 1, 2017, excess tax benefits and tax deficiencies will be reflected as income tax benefit or expense in our Consolidated Statement of Operations and could result in a material impact. The extent of the excess tax benefits or tax deficiencies are subject to variation in our stock price and the timing of RSU vestings and employee stock option exercises.

In February, 2016, FASB issued ASU 2016-02, “Leases (Topic 842)”, which amends the existing guidance to require lessees to recognize lease assets and lease liabilities from operating leases on the balance sheet. This ASU is effective using the modified retrospective approach for annual periods and interim periods within those annual periods beginning after December 15, 2018, which for us is the first fiscal quarter ending December 31, 2019. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2016-02 on our consolidated financial statements.

In January 2016, FASB issued ASU 2016-01, “Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 will require equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. The amendments in this update will also simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, eliminate the requirement for public business entities to disclose the method and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet and require these entities to use the exit price notion when measuring fair value of financial instruments for disclosure purposes. This ASU would also change the presentation and disclosure requirements for financial instruments. In addition, this ASU clarifies the guidance related to valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, which for us is the first fiscal quarter ending December 31, 2018. Early adoption is permitted for financial statements of fiscal years and interim periods that have not been issued. We are currently evaluating the impact of the adoption of ASU 2016-01.

In July 2015, FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” This provision would require inventory that was previously recorded using first-in, first-out (“FIFO”) to be recorded at lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This guidance is effective for fiscal years beginning after December 15, 2016 and interim periods within those years, which for us will be the first fiscal quarter ending December 31, 2017. The amendments in this guidance should be applied prospectively with earlier application permitted as of the beginning of an interim or annual period. We are currently evaluating the impact of the adoption of ASU 2015-11 and whether it would have a material impact on our consolidated financial statements.

In April 2015, FASB issued ASU 2015-05, “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” The new standard provides guidance to customers about whether a cloud computing arrangement includes a software license. If the arrangement does include a software license, the software license element of the arrangement should be accounted for in the same manner as the acquisition of other software licenses. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, with early adoption permitted. We expect to adopt this guidance beginning with our fiscal quarter ending December 31, 2016. We do not expect this guidance to have a material impact on our consolidated financial statements.

In August 2014, FASB issued ASU 2014-15, “Presentation of Financial Statements - Going Concern.” This guidance requires management to evaluate whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. These amendments are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter, which for us, will be our annual period ended September 30, 2017. Early adoption is permitted. While we are evaluating the impact of the adoption of ASU 2014-15, we do not expect it to have an impact on our consolidated financial statements.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

In May 2014, FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” This guidance provides a five-step analysis in determining when and how revenue is recognized so that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods and services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued ASU 2015-14 “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date” which approved a one-year deferral of the effective date of ASU 2014-09. As a result of this deferral, ASU 2014-09 is effective for our fiscal 2019, including interim periods within that reporting period. The FASB also agreed to allow us to choose to adopt the standard effective for our fiscal 2018. In addition, the FASB issued ASU 2016-08, ASU 2016-10 and ASU 2016-12 in March 2016, April 2016 and May 2016, respectively, to provide interpretive clarifications on the new guidance in ASC Topic 606. We are currently working through an adoption plan and have identified our revenue streams and completed a preliminary analysis of how we currently account for revenue transactions compared to the revenue accounting required under the new standard.  We intend to complete our adoption plan in fiscal 2017.  This plan includes a review of transactions supporting each revenue stream to determine the impact of accounting treatment under ASC 606, evaluation of the method of adoption, and completing a rollout plan for implementation of the new standard with affected functions in our organization.  Because of the nature of the work that remains, at this time we are unable to reasonably estimate the impact of adoption on our consolidated financial statements.  We plan to adopt the new guidance beginning October 1, 2018.

(1) During fiscal 2016 and 2015, we recorded net tax benefits of $1.5 million and $0.8 million, respectively. We recorded a benefit of $0.7 million in the first quarter of fiscal 2016 resulting from the reinstatement of the research and development tax credit for calendar year 2015, reversal of income tax reserves due to the expiration of the statute of limitations from various U.S. and foreign tax jurisdictions and reversal of tax reserves due to the resolution of tax audits. In the third quarter of fiscal 2016, we recorded a tax benefit of $0.5 million primarily due to the filing of an amended income tax return resulting in a domestic refund related to qualified manufacturing activities. In the fourth quarter of fiscal 2016, we recorded a net tax benefit of $0.2 million, primarily due to the filing of an additional amended income tax return resulting in an additional domestic refund related to qualified manufacturing activities, partially offset by an adjustment of the state rate on net deferred tax assets. We recorded net tax benefits of $0.5 million in the first quarter of fiscal 2015 resulting from the reinstatement of the research and development tax credit for calendar year 2014, reversal of income tax reserves due to the expiration of the statute of limitations from various U.S. and foreign tax jurisdictions and reversal of tax reserves due to the resolution of tax audits. In the third quarter of fiscal 2015, we recorded a tax benefit of $0.4 million primarily due to the reversal of reserves for state research and development tax credits and transfer pricing, partially offset by an adjustment of the state rate on net deferred tax assets.

18. QUARTERLY FINANCIAL DATA (UNAUDITED)(CONTINUED)

(2) For continuing operations, we recorded business restructuring charges of $0.7 million ($0.4 million after tax) in the first quarter of fiscal 2016, $0.1 million ($0.1 million after tax) in the second quarter of fiscal 2016 and $0.4 million ($0.3 million after tax) in the second quarter of fiscal 2015.

(3) During fiscal 2015, we recorded a gain of $1.4 million from the settlement of a property and casualty insurance claim related to the replacement of our capital equipment destroyed in the fire at our subcontract manufacturer's location. We recorded $1.0 million ($0.6 million after tax) during the second quarter of fiscal 2015 and $0.4 million ($0.3 million after tax) during the third quarter of fiscal 2015.

[1] During fiscal 2016 and 2015, we recorded net tax benefits of $1.5 million and $0.8 million, respectively. We recorded a benefit of $0.7 million in the first quarter of fiscal 2016 resulting from the reinstatement of the research and development tax credit for calendar year 2015, reversal of income tax reserves due to the expiration of the statute of limitations from various U.S. and foreign tax jurisdictions and reversal of tax reserves due to the resolution of tax audits. In the third quarter of fiscal 2016, we recorded a tax benefit of $0.5 million primarily due to the filing of an amended income tax return resulting in a domestic refund related to qualified manufacturing activities. In the fourth quarter of fiscal 2016, we recorded a net tax benefit of $0.2 million, primarily due to the filing of an additional amended income tax return resulting in an additional domestic refund related to qualified manufacturing activities, partially offset by an adjustment of the state rate on net deferred tax assets. We recorded net tax benefits of $0.5 million in the first quarter of fiscal 2015 resulting from the reinstatement of the research and development tax credit for calendar year 2014, reversal of income tax reserves due to the expiration of the statute of limitations from various U.S. and foreign tax jurisdictions and reversal of tax reserves due to the resolution of tax audits. In the third quarter of fiscal 2015, we recorded a tax benefit of $0.4 million primarily due to the reversal of reserves for state research and development tax credits and transfer pricing, partially offset by an adjustment of the state rate on net deferred tax assets.

[2] For continuing operations, we recorded business restructuring charges of $0.7 million ($0.4 million after tax) in the first quarter of fiscal 2016, $0.1 million ($0.1 million after tax) in the second quarter of fiscal 2016 and $0.4 million ($0.3 million after tax) in the second quarter of fiscal 2015.

[3] During fiscal 2015, we recorded a gain of $1.4 million from the settlement of a property and casualty insurance claim related to the replacement of our capital equipment destroyed in the fire at our subcontract manufacturer's location. We recorded $1.0 million ($0.6 million after tax) during the second quarter of fiscal 2015 and $0.4 million ($0.3 million after tax) during the third quarter of fiscal 2015.
