BASIS OF PRESENTATION OF UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND SIGNIFICANTACCOUNTING POLICIES	BASIS OF PRESENTATION OF UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The interim unaudited condensed consolidated financial statements included in this Form 10-Q have been prepared by Digi International Inc. (the “Company,” “Digi,” “we,” “our,” or “us”) pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures, normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto, including (but not limited to) the summary of significant accounting policies, presented in our Annual Report on Form 10-K for the year ended September 30, 2014 as filed with the SEC (“2014 Financial Statements”). The condensed consolidated financial statements presented herein reflect, in the opinion of management, all adjustments which consist only of normal, recurring adjustments necessary for a fair statement of the condensed consolidated balance sheets and condensed consolidated statements of operations, comprehensive income (loss) and cash flows for the periods presented. The condensed consolidated results of operations for any interim period are not necessarily indicative of results for the full year. The year-end condensed consolidated balance sheet data were derived from our 2014 Financial Statements, but do not include all disclosures required by U.S. GAAP. Recently Issued Accounting Pronouncements In April 2015, the Financial Accounting Standards Board (“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 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 July 2015, the FASB approved a one-year deferral of the effective date of ASU 2014-09, Revenue from Contracts with Customers. We can elect to adopt the provisions of ASU 2014-09 for annual periods beginning after December 15, 2017, including interim periods within that reporting period. The FASB also agreed to allow entities to choose to adopt the standard as of the original effective date. We are assessing the adoption date and potential impact of adopting this ASU on our consolidated financial statements and related disclosures.
