(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, 2012 as filed with the SEC (“2012 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 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 2012 Consolidated Financial Statements, but do not include all disclosures required by U.S. GAAP. Recently Issued Accounting Pronouncements Adopted In April 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2013-07, "Presentation of Financial Statements (Topic 205); Liquidation Basis of Accounting." The objective of this guidance is to clarify when an entity should apply the liquidation basis of accounting and to provide principles for the measurement of assets and liabilities under the liquidation basis of accounting, as well as any required disclosures. The amendments in this standard are effective prospectively for entities that determine liquidation is imminent during annual reporting periods beginning after December 15, 2013, and interim reporting periods therein. Early adoption is permitted. We adopted this guidance in the third quarter of fiscal 2013. Since liquidation is not imminent, the adoption did not have an impact on our consolidated financial statements. In February 2013, the FASB issued ASU 2013-02, "Comprehensive Income (Topic 220); Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." This updated guidance improves the reporting of significant items reclassified out of accumulated other comprehensive income and requires an entity to present, either on the face of the statement where net income is presented or in the notes, separately for each component of comprehensive income, the current period reclassifications out of accumulated other comprehensive income by the respective line items of net income affected by the reclassification. The updated guidance is effective prospectively for reporting periods beginning after December 15, 2012. We adopted this guidance beginning January 1, 2013. Other than requiring additional disclosures that are in the footnotes to the Condensed Statements of Comprehensive Income (Loss), the adoption did not have an effect on our consolidated financial statements. Not Adopted In March 2013, the FASB issued ASU 2013-05, "Foreign Currency Matters (Topic 830); Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity." This guidance applies to the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity. ASU No. 2013-05 is effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. We will adopt this guidance beginning with our fiscal quarter ending December 31, 2014. We currently are reviewing the provisions of ASU No. 2013-05 but do not expect it to have an effect on our consolidated financial statements as we do not intend to sell any foreign entities for which we hold a controlling financial interest.
