Basis of Presentation	Basis of Presentation The condensed consolidated financial data at December 31, 2015 is derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2015 filed with the Securities and Exchange Commission (“SEC”) on March 11, 2016 (“Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, operating results and cash flows in conformity with GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in our Form 10-K. All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the operating results for the period presented have been included in the interim period. Operating results for the three months ended March 31, 2016 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2016. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. As permitted under GAAP, interim accounting for certain expenses, including income taxes, are based on full year forecasts. For interim financial reporting purposes, income taxes are recorded based upon estimated annual effective income tax rates taking into consideration discrete items occurring in a quarter. Dollar amounts and share amounts are presented in thousands, except per share amounts, unless otherwise noted. Certain prior year’s balances have been reclassified to conform to the current financial statement presentation.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements The Financial Accounting Standards Board (“FASB”) issued the following Accounting Standards Updates (“ASU”) which could have potential impact to the Company’s financial statements: ASU No. 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Cost (“ASU 2015-03”). This standard requires that costs associated with the issuance of debt previously recorded as deferred assets on the balance sheet now are reported as a direct reduction of the related debt balance. This standard is effective for interim and annual periods beginning January 1, 2016, but early adoption is permitted. We adopted this standard in the first quarter of 2016 and applied the standard retrospectively to all prior periods presented. The adoption of ASU 2015-03 resulted in a $2.2 million retrospective reduction of both our other assets and long-term notes payable, net of current portion, as of December 31, 2015. Adoption of this standard had no impact on the consolidated statements of operations. ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16"). This standard eliminates the requirement for an acquirer to retrospectively adjust the financial statements for measurement-period adjustments that occur in periods after a business combination is consummated. These changes became effective for fiscal years beginning after December 31, 2015. We adopted this standard in the first quarter of 2016 and had adjustments to the previously reported fair values recorded related to the Pericom transaction. See Note 11 for additional information related to these adjustments. Adoption of this standard had no impact on the consolidated statements of operations. ASU No. 2016-07, Investments-Equity Method and Joint Ventures (Topic 323) (“ASU 2016-07”). The amendments in this update eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this update require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. We are evaluating the effect that ASU 2016-07 will have on our consolidated financial statements and related disclosures. ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). This standard is designed to make accounting for share-based payment transactions less complex for public and private companies. The areas for simplification in this update involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public business entities, the amendments in this update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. We are evaluating the effect ASU 2016-09 will have on our consolidated financial statements and related disclosures.
