Organization Consolidation And Presentation Of Financial Statements [Abstract]
Financial Statement Presentation and Significant Accounting Policies	NOTE 2 — FINANCIAL STATEMENT PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES The accompanying unaudited condensed consolidated financial statements include the accounts of Signature, its wholly owned subsidiaries and its majority owned subsidiaries (collectively, the “Company”). The Company accounts for investments in companies over which it has the ability to exercise significant influence, but does not hold a controlling interest, under the equity method of accounting, and records its proportionate share of income or losses in other income (expense) in the unaudited condensed consolidated statements of operations. The Company accounts for investments in companies over which it does not have the ability to exercise significant influence under the cost method of accounting. These investments are carried at cost within other noncurrent assets in the unaudited condensed consolidated balance sheets. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments considered necessary for a fair presentation, have been included. The Company evaluates subsequent events through the date of filing with the Securities and Exchange Commission (“SEC” or “Commission”). Operating results for the nine months ended September 30, 2014 are not indicative of the results that may be expected for the year ending December 31, 2014. These interim period unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of and for the year ended December 31, 2013, which are included in the Company’s Annual Report on Form 10-K, as filed with the SEC on March 13, 2014 (the “Annual Report”). Certain amounts in the accompanying unaudited condensed consolidated financial statements have been reclassified to conform to the current presentation, including the reclassification of Cosmed, Inc. (“Cosmed”), into continuing operations, following suspension of the Company’s efforts to sell Cosmed in April 2014. The Company’s significant accounting policies are disclosed in the consolidated financial statements included in Part IV, Item 15 of the Annual Report, and there have been no material changes to those accounting policies during the nine months ended September 30, 2014. Recent accounting standards updates In April 2014, the Financial Accounting Standards Board (“FASB”) issued accounting guidance (Topic 250, Presentation of Financial Statements and Topic 360, Property, Plant and Equipment) that changes the criteria for reporting discontinued operations and enhances related disclosures. Under the new guidance, only disposals representing a strategic shift in operations are presented as discontinued operations. Those strategic shifts should have a major effect on the organization’s operations and financial results. Additionally, the new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income and expenses of discontinued operations. The new guidance is effective for annual reporting periods beginning after December 15, 2014, including interim reporting periods within that reporting period. Early adoption is permitted, but only for certain disposals. The new guidance is not expected to have a significant impact on the Company’s consolidated financial statements or disclosures. In May 2014, the FASB issued accounting guidance (Topic 606, Revenue from Contracts with Customers) that supersedes existing revenue recognition guidance and most industry-specific revenue recognition guidance. The new guidance is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The new guidance is effective for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period and early application is not permitted. The Company is currently assessing the impact of the new guidance on its consolidated financial statements and disclosures. In June 2014, the FASB issued accounting guidance (Topic 718, Stock Compensation) on share-based compensation with performance targets. The new guidance provides that an equity grant performance target that affects vesting, and could be achieved after the requisite service period, be treated as a performance condition. The new guidance is effective for annual reporting periods beginning after December 15, 2015, including interim reporting periods within that reporting period. Early adoption is permitted and entities may apply the new guidance either: (a) prospectively to all awards granted or modified after the effective date; or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The new guidance is not expected to have a significant impact on the Company’s consolidated financial statements or disclosures.
