Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND BUSINESS	ORGANIZATION AND BUSINESS On May 29, 2014, HC2 Holdings, Inc. (“HC2” and, together with its subsidiaries, the “Company”, “we” and “our”) completed the acquisition of 2.5 million shares of common stock of Schuff International, Inc. (“Schuff”), a steel fabrication and erection company, and negotiated an agreement to purchase an additional 198,411 shares, representing an approximately 65% interest in Schuff. The aggregate consideration for the shares of Schuff acquired was approximately $85 million , which was funded using the net proceeds from (i) the issuance of $30 million of Series A Convertible Participating Preferred Stock of HC2 (the “Series A Preferred Stock”) and $6 million of common stock of HC2, and (ii) the entry into a senior secured credit facility providing for an eighteen month, floating interest rate term loan of $80 million (the “May Credit Facility”), each of which was also completed on May 29, 2014. Schuff repurchased a portion of its outstanding common stock in June 2014, which had the effect of increasing the Company’s ownership interest to 70% . During the fourth quarter of 2014, the final results of a tender offer for all outstanding shares of Schuff were announced and various open-market purchases were made, which resulted in the acquisition of 809,043 shares and an increase in our ownership interest to 91% . We intend to execute a short-form merger, which will increase our ownership of Schuff shares to 100% . Schuff and its wholly-owned subsidiaries primarily operate as integrated fabricators and erectors of structural steel and heavy steel plates with headquarters in Phoenix, Arizona and operations in Arizona, Georgia, Texas, Kansas and California. Schuff’s construction projects are primarily in the aforementioned states. In addition, Schuff has construction projects in select international markets, primarily Panama. Schuff has a 49% interest in Schuff Hopsa Engineering, Inc. (“SHE”), a Panamanian joint venture with Empresas Hopsa, S.A., that provides steel fabrication services. Schuff controls the operations of SHE, as provided in the operating agreement. Therefore, the assets, liabilities, revenues and expenses of SHE are included in the Condensed Consolidated Financial Statements of Schuff. Empresas Hopsa, S.A.’s 51% interest in SHE is presented as a noncontrolling interest component of total stockholders’ equity. On August 1, 2014, the Company paid $15.5 million to acquire 15,500 shares of Series A Convertible Preferred Stock of American Natural Gas (“ANG”), representing an approximately 51% interest in ANG. ANG is a premier distributor of natural gas motor fuel headquartered in the Northeast that designs, builds, owns, acquires, operates and maintains compressed natural gas fueling stations for transportation. On September 22, 2014, the Company completed the acquisition of Bridgehouse Marine Limited (“Bridgehouse”), the parent holding company of Global Marine Systems Limited (“GMSL”). The purchase price reflects an enterprise value of approximately $260 million , including assumed indebtedness, and was funded using a portion of the net proceeds from (i) the issuance of $11 million of Series A-1 Convertible Participating Preferred Stock of HC2 (the “Series A-1 Preferred Stock”) and (ii) a senior secured credit facility providing for a twelve month, floating interest rate term loan of $214 million and a delayed draw term loan of $36 million (the “September Credit Facility”), each of which was also completed on September 22, 2014. With a portion of the proceeds from the September Credit Facility, the Company paid off its May Credit Facility and its senior unsecured credit facility consisting of a term loan of $17 million entered into on September 8, 2014 (the “Novatel Acquisition Term Loan”) for the purpose of acquiring an ownership interest in Novatel Wireless, Inc. The September Credit Facility was subsequently repaid using the proceeds from HC2’s issuance of its Existing Notes discussed below under Note 8—“Long-Term Obligations”. GMSL is a leading provider of engineering and underwater services on submarine cables. In conjunction with the acquisition, approximately 3% of the Company’s interest in GMSL was purchased by a group of individuals, leaving the Company’s controlling interest as of March 31, 2015 at approximately 97% . In our Telecommunications segment, we operate a telecommunications business including a network of direct routes and provide premium voice communication services for national telecom operators, mobile operators, wholesale carriers, prepaid operators, Voice over Internet Protocol (“VoIP”) service operators and Internet service providers (“ISPs”) from our International Carrier Services (“ICS”) business unit. In our Life Sciences segment, we operate Pansend, LLC (“Pansend”), which has an 80% interest in Genovel Orthopedics, Inc., which seeks to develop products to treat early osteoarthritis of the knee, and a 61% interest in R2 Dermatology (f/k/a “GemDerm Aesthetics, Inc.”), which develops skin lightening technology. Additionally, in 2014 we acquired a 100% ownership interest in DMi, Inc. (“DMi”), which owns licenses to create and distribute NASCAR ® video games. The Company currently has six reportable operating segments based on management’s organization of the enterprise—Manufacturing (Schuff), Marine Services (GMSL), Utilities (ANG), Telecommunications (ICS), Life Sciences and Other, which includes operations that do not meet the separately reportable segment thresholds. HC2 was formed as a corporation under the laws of Delaware in 1994 and operates as a holding company of operating subsidiaries primarily in the United States and the United Kingdom. Restatement of Consolidated Financial Statements On February 21, 2016, the Company determined that it needed to restate previously reported financial statements for the year ended December 31, 2014 and the fiscal quarters ended June 30, 2014, September 30, 2014, March 31, 2015, June 30, 2015 and September 30, 2015 to correct errors resulting from material weaknesses that the Company identified in its internal control over accounting for income taxes, valuation of a business acquisition and the application of generally accepted accounting principles (GAAP) to complex and/or non-routine transactions. In particular, the Company is restating its Condensed Consolidated Financial Statements for the three months ended March 31, 2015 to correct the improper recording of items related to the following: • The Company completed the acquisition of GMSL on September 22, 2014, but treated the acquisition as having closed on September 30, 2014. As a result, eight days of activity were excluded from the results of operations. In addition, the Company subsequently identified items related to the opening balance sheet as well as conforming balance sheet reclassifications related to the purchase accounting for GMSL. • The Company incorrectly valued our share-based compensation expense. Options were entitled to be received between May and September of 2014, but which were actually issued on October 28, 2014. The Company incorrectly recorded the fair value of the options using the issuance date of October 28, 2014 rather than the earlier measurement date under US GAAP. • The Company amended the valuation of the ANG business acquisition which resulted in goodwill. • The Company reclassified redeemable non-controlling interest from permanent equity to temporary equity. • The Company identified other income which was recognized in the three months ended September 30, 2015, but should have been recorded in the three months ended March 31, 2015 and June 30, 2015. • The Company reclassified certain pension liabilities between current and non-current as well as accrued expenses and other current assets. • The Company corrected the March 31, 2014 Condensed Consolidated Statement of Cash Flows to reclassify funds released from escrow which related to the sale of business units from operating activities to investing activities. As a result, the Company concluded that the financial statements for the three month period ended March 31, 2015 were materially misstated. The consolidated statement of operations, consolidated statement of comprehensive income (loss), consolidated balance sheets, consolidated statement of stockholders' equity and consolidated statement of cash flows, as well as the corresponding Notes to the Condensed Consolidated Financial Statements have been restated to reflect the correction of the aforementioned errors. The following tables provide a reconciliation of the amounts previously reported to the restated amounts for the quarter ended March 31, 2015: HC2 HOLDINGS, INC.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	3 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation —The accompanying unaudited Condensed Consolidated Financial Statements of HC2 have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial reporting and Securities and Exchange Commission (“SEC”) regulations. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such principles and regulations. In the opinion of management, the financial statements reflect all adjustments (all of which are of a normal and recurring nature), which are necessary to present fairly the financial position, results of operations, cash flows and comprehensive income (loss) for the interim periods. The results for the Company’s three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 . The financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in the Company’s most recently filed Annual Report on Form 10-K/A. Principles of Consolidation —The Condensed Consolidated Financial Statements include the accounts of the Company, its wholly owned subsidiaries and all other subsidiaries over which the Company exerts control. All intercompany profits, transactions and balances have been eliminated in consolidation. As of March 31, 2015, the Company has a 97% interest in GMSL, a 91% interest in Schuff, a 51% interest in ANG and a 100% interest in DMi. Through its subsidiary, Pansend, the Company has an 80% interest in Genovel Orthopedics, Inc. and a 61% interest in R2 Dermatology (f/k/a “GemDerm Aesthetics, Inc.”). The results of each of these entities are consolidated with the Company’s results from and after their respective acquisition dates based on guidance from the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) No. 810, “Consolidation” (“ASC 810”). The remaining interests not owned by the Company are presented as a noncontrolling interest component of total equity. Schuff uses a 4-4-5 week quarterly cycle, which for the first quarter of 2015 ended on March 29, 2015. Foreign Currency Transactions —Foreign currency transactions are transactions denominated in a currency other than a subsidiary’s functional currency. A change in the exchange rates between a subsidiary’s functional currency and the currency in which a transaction is denominated increases or decreases the expected amount of functional currency cash flows upon settlement of the transaction. That increase or decrease in expected functional currency cash flows is reported by the Company as a foreign currency transaction gain (loss). Foreign Currency Translation —The assets and liabilities of the Company’s foreign subsidiaries are translated at the exchange rates in effect on the reporting date. Income and expenses are translated at the average exchange rate during the period. The net effect of such translation gains and losses are reflected within accumulated other comprehensive income (loss) in the stockholders’ equity section of the condensed consolidated balance sheets. Inventories Schuff—Inventories, primarily steel components, are stated at the lower of cost or market under the first-in, first-out method. GMSL—Inventory is valued at the lower of cost or market value under the first-in first-out method. Provision for obsolescence is made where appropriate and is charged to cost of revenue in the condensed consolidated statements of operations. Short-term work in progress on contracts is stated at cost less foreseeable losses. These costs include only direct labor and expenses incurred to date and exclude any allocation of overhead. The policy for long-term work in progress contracts is disclosed within the Revenue and Cost Recognition accounting policy for GMSL. Short-term Investments —The current investments are classified as available-for-sale securities and the change in value is recognized within accumulated other comprehensive income (loss). Long-term Investments —Investments in non-wholly-owned companies are generally consolidated if the Company’s interest exceeds 50% or if the Company has the power to direct the economic activities of the entity and the obligation to absorb losses, or accounted for under the equity method of accounting when the Company exercises significant influence over the venture. Under the equity method of accounting, the Company records its proportionate interest in the underlying income or loss of the equity method investee. Additional investments made or distributions received are recorded as increases and decreases, respectively, to the carrying value of the equity method investment. Equity method investments are evaluated for potential impairment as circumstances warrant and an impairment charge is recorded when an impairment is deemed to be other-than-temporary. When the Company’s investment in an equity method investee is greater than its proportionate share of the underlying net assets of that investee, a basis difference is created under ASC No. 323, “Investments—Equity Method and Joint Ventures” (“ASC 323”). When this situation occurs, the Company is required to determine the acquisition date fair value of the identifiable assets and assumed liabilities in the same manner as for a business combination under ASC No. 805, “Business Combinations” (“ASC 805”). If the basis difference is assigned to amortizable assets, it is amortized (net of tax) against the Company’s investment in the equity method investee. Property, Plant and Equipment —Property, plant and equipment are stated at cost less accumulated depreciation, which is provided on the straight-line method over the estimated useful lives of the assets. Cost includes major expenditures for improvements and replacements which extend useful lives or increase capacity of the assets as well as expenditures necessary to place assets into readiness for use. Cost includes the original purchase price of the asset and the costs attributable to bringing the asset to its working condition for its intended use. Cost includes finance costs incurred prior to the asset being available for use. Expenditures for maintenance and repairs are expensed as incurred. Depreciation is determined on a straight-line basis over the estimated useful lives of the assets, which range from 15 to 40 years for buildings and improvements, up to 35 years for cable-ships and submersibles, 3 to 15 years for machinery and equipment, and 3 to 20 years for plant and motor vehicles. Plant includes equipment on the cable-ships that is portable and can be moved around the fleet and computer equipment. Leasehold improvements are amortized over the lives of the leases or estimated useful lives of the assets, whichever is shorter. Assets under construction are not depreciated until they are complete and available for use. Costs for internal use software that are incurred in the preliminary project stage and in the post-implementation stage are expensed as incurred. Costs incurred during the application development stage are capitalized and amortized over the estimated useful life of the software. When assets are sold or otherwise retired, the costs and accumulated depreciation are removed from the books and the resulting gain or loss is included in operating results. Property, plant and equipment that have been included as part of the assets held for sale are no longer depreciated from the time that they are classified as such. The Company periodically evaluates the carrying value of its property, plant and equipment based upon the estimated cash flows to be generated by the related assets. If impairment is indicated, a loss is recognized. Use of Estimates —The preparation of Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of net revenue and expenses during the reporting period. Actual results may differ from these estimates. Significant estimates include allowance for doubtful accounts receivable, the extent of progress towards completion on contracts, contract revenue and costs on long-term contracts, market assumptions used in estimating the fair values of certain assets and liabilities, the calculation used in determining the fair value of HC2’s stock options required by ASC No. 718, “Compensation—Stock Compensation” (“ASC 718”), income taxes and various other contingencies. Estimates of fair value represent the Company’s best estimates developed with the assistance of independent appraisals or various valuation techniques and, where the foregoing have not yet been completed or are not available, industry data and trends and by reference to relevant market rates and transactions. The estimates and assumptions are inherently subject to significant uncertainties and contingencies beyond the control of the Company. Accordingly, the Company cannot provide assurance that the estimates, assumptions, and values reflected in the valuations will be realized, and actual results could vary materially. Revenue and Cost Recognition GMSL —GMSL generates revenue by providing maintenance services for subsea telecommunications cabling. GMSL also generates revenue from the design and installation of subsea cables under contracts. GMSL also provides installation, maintenance and repair of fiber optic communication and power infrastructure to offshore oil and gas platforms and installs inter-array power cables for use in offshore wind farms and in the offshore wind market. Telecommunication/Maintenance—GMSL provides vessels on standby to repair fiber optic telecommunications cables in defined geographic zones, and its maintenance business is provided through contracts with consortia of up to 60 global telecommunications providers. Typically, GMSL enters into five to seven year contracts to provide maintenance to cable systems that are located in specific geographical areas. Revenue from these maintenance agreements is recognized on a straight line basis unless the pattern of costs associated with repairs indicates otherwise. Telecommunications/Installation—GMSL provides installation of cable systems including route planning, mapping, route engineering, cable laying, and trenching and burial. GMSL’s installation business is project-based with fixed price contracts typically lasting one to five months . Revenue is recognized as time and costs are incurred. Charter hire — rentals from short term operating leases in respect of vessels are recognized as revenue on a straight line basis over the term of the lease. Oil & Gas — GMSL provides installation, maintenance and repair of fiber optic communication and power infrastructure to offshore platforms. Its primary activities include providing power from shore, enabling fiber-based communication between platforms and shore-based systems and installing permanent reservoir monitoring systems which allow customers to monitor subsea seismic data. The majority of GMSL’s oil & gas business is contracted on a project-by-project basis with major energy producers or tier I engineering, procurement and construction (EPC) contractors. Revenue is recognized as time and costs are incurred. A loss is recognized immediately if the expected costs during any contract exceed expected revenues. Amounts billed in advance of revenue recognition are recorded as deferred revenue. Schuff —Schuff performs its services primarily under fixed-price contracts and recognizes revenues and costs from construction projects using the percentage of completion method. Under this method, revenue is recognized based upon either the ratio of the costs incurred to date to the total estimated costs to complete the project or the ratio of tons fabricated to date to total estimated tons. Revenue recognition begins when work has commenced. Costs include all direct material and labor costs related to contract performance, subcontractor costs, indirect labor, and fabrication plant overhead costs, which are charged to contract costs as incurred. Revenues relating to changes in the scope of a contract are recognized when the work has commenced, Schuff has made an estimate of the amount that is probable of being paid for the change and there is a high degree of probability that the charges will be approved by the customer or general contractor. At March 31, 2015, Schuff had $66.9 million of unapproved change orders on open projects, for which it has recognized revenues on a percentage of completion basis. While Schuff has been successful in having the majority of its change orders approved in prior years, there is no guarantee that the unapproved change orders at March 31, 2015 will be approved. Revisions in estimates during the course of contract work are reflected in the accounting period in which the facts requiring the revision become known. Provisions for estimated losses on uncompleted contracts are made in the period a loss on a contract becomes determinable. Construction contracts with customers generally provide that billings are to be made monthly in amounts which are commensurate with the extent of performance under the contracts. Contract receivables arise principally from the balance of amounts due on progress billings on jobs under construction. Retentions on contract receivables are amounts due on progress billings, which are withheld until the completed project has been accepted by the customer. Costs and recognized earnings in excess of billings on uncompleted contracts primarily represent revenue earned under the percentage of completion method which has not been billed. Billings in excess of related costs and recognized earnings on uncompleted contracts represent amounts billed on contracts in excess of the revenue allowed to be recognized under the percentage of completion method on those contracts. ICS —Net revenue is derived from carrying a mix of business, residential and carrier long-distance traffic, data and Internet traffic. For certain voice services, net revenue is earned based on the number of minutes during a call, and is recorded upon completion of a call. Revenue for a period is calculated from information received through the Company’s network switches. Customized software has been designed to track the information from the switch and analyze the call detail records against stored detailed information about revenue rates. This software provides the Company the ability to do a timely and accurate analysis of revenue earned in a period. Separate prepaid services software is used to track additional information related to prepaid service usage such as activation date, monthly usage amounts and expiration date. Revenue on these prepaid services is recognized as service is provided until expiration, when all unused minutes, which are no longer available to the customers, are recognized as revenue. Net revenue is also earned on a fixed monthly fee basis for unlimited local and long-distance voice plans and for the provision of data/Internet services (including retail VoIP), hosting, and colocation. In the United States, we charge customers Federal Universal Service Fund (“USF”) fees. We recognize revenue on a gross basis for USF and related fees. We record these fees as revenue when billed. Net revenue represents gross revenue, net of allowance for doubtful accounts receivable, service credits and service adjustments. Cost of revenue includes network costs that consist of access, transport and termination costs. The majority of the Company’s cost of revenue is variable, primarily based upon minutes of use, with transmission and termination costs being the most significant expense. Cost of revenue also includes fees such as Federal USF fees. Such costs are recognized when incurred in connection with the provision of telecommunications services. Share-Based Compensation —The Company accounts for share-based compensation under ASC No. 718, “Compensation—Stock Compensation” (“ASC 718”), which addresses the accounting for share-based payment transactions whereby an entity receives employee services in exchange for equity instruments, including stock options and restricted stock units. ASC 718 generally requires that share-based compensation be accounted for using a fair-value based method. The Company records share-based compensation expense for all new and unvested stock options that are ultimately expected to vest as the requisite service is rendered. The Company issues new shares of common stock upon the exercise of stock options. The Company elected to adopt the alternative transition method for calculating the tax effects of share-based compensation. The alternative transition method includes simplified methods to determine the beginning balance of the additional paid in capital (“APIC”) pool related to the tax effects of share-based compensation and to determine the subsequent impact on the APIC pool and the statement of cash flows of the tax effects of share-based awards that were fully vested and outstanding upon the adoption of ASC 718. The Company uses a Black-Scholes option valuation model to determine the fair value of share-based compensation under ASC 718. The Black-Scholes model incorporates various assumptions including the expected term of awards, volatility of stock price, risk-free rates of return and dividend yield. The expected term of an award is no less than the option vesting period and is based on the Company’s historical experience. Expected volatility is based upon the historical volatility of the Company’s stock price. The risk-free interest rate is approximated using rates available on U.S. Treasury securities with a remaining term similar to the option’s expected life. The Company uses a dividend yield of zero in the Black-Scholes option valuation model as it does not anticipate paying cash dividends in the foreseeable future that do not contain antidilution provisions requiring the adjustment of exercise prices and option shares. Share-based compensation is recorded net of expected forfeitures. Income (Loss) Per Common Share —Basic income (loss) per common share is computed using the weighted average number of shares of common stock outstanding during the period. Diluted income (loss) per common share is computed using the weighted average number of shares of common stock, adjusted for the dilutive effect of potential common stock and related income from continuing operations, net of tax. Potential common stock, computed using the treasury stock method or the if-converted method, includes options, restricted stock, restricted stock units and convertible preferred stock. In periods when the Company generates income, the Company calculates basic earnings per share using the two-class method, pursuant to ASC No. 260, “Earnings Per Share.” The two-class method is required as the shares of the Company’s Preferred Stock qualify as participating securities, having the right to receive dividends should dividends be declared on common stock. Under this method, earnings for the period are allocated on a pro-rata basis to the common stockholders and to the holders of preferred stock based on the weighted average number of common shares outstanding and the number of shares that could be converted. The Company does not use the two-class method in periods when it generates a loss as the holders of the Preferred Stock do not participate in losses. Reclassification —Certain previous year amounts have been reclassified to conform with current year presentations, as related to the reporting of new balance sheet line items. Newly Adopted Accounting Principles In April 2014, an update was issued to the Presentation of Financial Statements Topic No. 205 and Property, Plant and Equipment Topic No. 360, ASU 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity”, which changes the criteria for reporting discontinued operations. The ASU revises the definition of a discontinued operation and expands the disclosure requirements. Entities should not apply the amendments to a component of an entity that is classified as held for sale before the effective date even if it is disposed of after the effective date. That is, the ASU must be adopted prospectively. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been previously reported in the financial statements. On January 1, 2015, the Company adopted this update, which did not have a material impact on the Condensed Consolidated Financial Statements. New Accounting Pronouncements In February 2015, the FASB issued ASU 2015-02, “Amendments to the Consolidation Analysis”, which amends the consolidation requirements in ASC 810 and significantly changes the consolidation analysis required under U.S. GAAP relating to whether or not to consolidate certain legal entities. Early adoption is permitted. The Company’s effective date for adoption is January 1, 2016. The Company does not expect this accounting update to have a material effect on its consolidated financial statements in future periods, although that could change. In January 2015, the FASB issued ASU 2015-01, “Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items”, which eliminates the concept from U.S. GAAP the concept of an extraordinary item. Under the ASU, an entity will no longer (1) segregate an extraordinary item from the results of ordinary operations; (2) separately present an extraordinary item on its income statement, net of tax, after income from continuing operations; or (3) disclose income taxes and earnings-per-share data applicable to an extraordinary item. Early adoption is permitted. The Company’s effective date for adoption is January 1, 2016. The Company does not expect this accounting update to have a material effect on its consolidated financial statements in future periods, although that could change.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS The Company’s acquisitions were accounted for using the acquisition method of accounting which requires, among other things, that assets acquired and liabilities assumed be recognized at their estimated fair values as of the acquisition date. Estimates of fair value included in the Condensed Consolidated Financial Statements, in conformity with ASC No. 820, “Fair Value Measurements and Disclosures” (“ASC 820”), represent the Company’s best estimates and valuations developed with the assistance of independent appraisers and, where such valuations have not yet been completed or are not available, industry data and trends and by reference to relevant market rates and transactions. The following estimates and assumptions are inherently subject to significant uncertainties and contingencies beyond the control of the Company. Accordingly, the Company cannot provide assurance that the estimates, assumptions, and values reflected in the valuations will be realized, and actual results could vary materially. Any changes to the initial estimates of the fair value of the assets and liabilities will be recorded as adjustments to those assets and liabilities and residual amounts will be allocated to goodwill. In accordance with ASC 805, if additional information is obtained about these assets and liabilities within the measurement period (not to exceed one year from the date of acquisition), including finalization of asset appraisals, the Company will refine its estimates of fair value to allocate the purchase price more accurately. Schuff On May 29, 2014, the Company completed the acquisition of 2.5 million shares of common stock of Schuff, a steel fabrication and erection company and negotiated an agreement to purchase an additional 198,411 shares, representing an approximately 65% interest in Schuff. Schuff repurchased a portion of its outstanding common stock in June 2014, which had the effect of increasing the Company’s ownership interest to 70% . During the fourth quarter, the final results of a tender offer for all outstanding shares of Schuff were announced and various open-market purchases were made, which resulted in the acquisition of 809,043 shares and an increase in our ownership interest to 91% . We intend to execute a short-form merger, which will increase our ownership of Schuff shares to 100% . Schuff and its wholly-owned subsidiaries primarily operate as integrated fabricators and erectors of structural steel and heavy steel plates with headquarters in Phoenix, Arizona and operations in Arizona, Georgia, Texas, Kansas and California. Schuff’s construction projects are primarily in the aforementioned states. In addition, Schuff has construction projects in select international markets, primarily Panama. The Company acquired Schuff to diversify its portfolio of holdings and saw Schuff as an opportunity to enter the steel fabrication and erection market. The table below summarizes the preliminary estimates of fair value of the Schuff assets acquired and liabilities assumed as of the acquisition date. The Company purchased 2.5 million shares of common stock of Schuff for $78.75 million . The purchase price of Schuff was valued at $31.50 per share which represented both the cash paid by the Company for its 60% interest, and the fair value of the noncontrolling interest of 40% . The preliminary purchase price allocation is as follows (in thousands): Cash and cash equivalents $ (627 ) Investments 1,714 Accounts receivable 130,622 Costs and recognized earnings in excess of billings on uncompleted contracts 27,126 Prepaid expenses and other current assets 3,079 Inventories 14,487 Assets held for sale — Property and equipment, net 85,662 Goodwill 24,612 Trade names 4,478 Other assets 2,947 Total assets acquired 294,100 Accounts payable 37,621 Accrued payroll and employee benefits 11,668 Accrued expenses and other current liabilities 12,532 Billings in excess of costs and recognized earnings on uncompleted contracts 65,985 Accrued income taxes 1,202 Accrued interest 76 Current portion of long-term debt 15,460 Liabilities held for sale — Long-term debt 4,375 Deferred tax liability 7,815 Other liabilities 604 Noncontrolling interest 4,365 Total liabilities assumed 161,703 Enterprise value 132,397 Less fair value of noncontrolling interest 53,647 Purchase price attributable to controlling interest $ 78,750 The acquisition of Schuff resulted in goodwill of approximately $24.6 million . Goodwill was the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Goodwill was recognized as a new stand-alone reporting unit. Goodwill is not amortized and is not deductible for tax purposes. The acquired amortizable intangible assets and the related estimated useful lives consist of the following (in thousands): Preliminary Estimated Useful Lives Preliminary Estimated Value May 29, 2014 Trade names 15 years $ 4,478 Total intangible assets $ 4,478 ASC 810 requires that transactions that result in an increase in ownership of a subsidiary be accounted for as equity transactions. The carrying amount of the noncontrolling interest is adjusted to reflect the controlling interest’s decreased ownership interest in the subsidiary’s net assets and any difference between the consideration paid by the parent to a noncontrolling interest holder (or contributed by the parent to the net assets of the subsidiary) and the adjustment to the carrying amount of the noncontrolling interest in the subsidiary is recognized directly in equity attributable to the controlling interest. Due to the increase of the Company’s ownership to 91% from the acquisition date through December 31, 2014 , the Company recorded an adjustment of Schuff’s noncontrolling interest by $3.4 million and recorded as excess book value over fair value of purchased noncontrolling interest in the Company’s condensed consolidated statement of stockholders’ equity. In the three months ended March 31, 2015, the Company acquired an additional 6,800 shares of Schuff that resulted in less than $0.1 million of excess book value over fair value of purchased noncontrolling interest in the Company’s condensed consolidated statement of stockholders’ equity. The ownership interest of 91% did not change. ANG On August 1, 2014, the Company paid $15.5 million to acquire 15,500 shares of Series A Convertible Preferred Stock of ANG (the “ANG Preferred Stock”), representing an approximately 51% interest in ANG. The ANG Preferred Stock is convertible into 1,033,333 shares of common stock and also has voting rights. The noncontrolling interest represents 1,000,000 shares of common stock; thereby giving the Company a controlling interest. ANG is a premier distributor of natural gas motor fuel headquartered in the Northeast that designs, builds, owns, operates and maintains compressed natural gas fueling stations for transportation. The Company acquired ANG for its strong growth potential which is in line with the Company’s strategy to find investments that can generate high returns and significant cash flow. The table below summarizes the fair value of the ANG assets acquired and liabilities assumed as of the acquisition date. The purchase price of ANG was valued at $23.7 million which represented both the cash paid by the Company for its 51% interest ( $15.5 million ), and the fair value of the noncontrolling interest of 49% , which was determined by an outside appraisal to be $8.2 million . The purchase price allocation as restated is as follows (in thousands): Cash and cash equivalents $ 15,704 Accounts receivable 306 Prepaid expenses and other current assets 31 Inventories 27 Property and equipment, net 1,921 Customer contracts 2,700 Trade names 6,300 Other assets 2 Goodwill 1,374 Total assets acquired 28,365 Accounts payable 49 Accrued payroll and employee benefits 5 Accrued expenses and other current liabilities 26 Billings in excess of costs and recognized earnings on uncompleted contracts 114 Current portion of long-term debt 34 Long-term debt 870 Deferred tax liability 3,530 Total liabilities assumed 4,628 Enterprise value 23,737 Less fair value of non-controlling interest 8,237 Purchase price attributable to controlling interest $ 15,500 The acquisition of ANG resulted in goodwill of approximately $1.4 million . Goodwill was the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Goodwill was recognized as a new stand-alone reporting unit. Goodwill is not amortized and is not deductible for tax purposes. The acquired amortizable intangible assets and the related estimated useful lives consist of the following (in thousands): Useful Lives Value August 1, 2014 Customer contracts 4 years $ 2,700 Trade names 15 years 6,300 Total intangible assets $ 9,000 GMSL On September 22, 2014, the Company completed the acquisition of Bridgehouse and its subsidiary, GMSL. The purchase price reflects an enterprise value of approximately $260 million , including assumed indebtedness of approximately $130 million leaving a net enterprise value of approximately $130 million . GMSL is a leading provider of engineering and underwater services on submarine cables. The Company acquired GMSL for its attractive valuation and strong cash position. The table below summarizes the preliminary estimates of fair value of the GMSL assets acquired and liabilities assumed as of the acquisition date. The net enterprise value of GMSL was valued at $130.4 million which represented both the cash paid by the Company for its 97% interest, and the fair value of the noncontrolling interest of 3% . The purchase price allocation as restated is as follows (in thousands): Cash and cash equivalents $ 62,555 Accounts receivable 22,381 Prepaid expenses and other current assets 23,108 Inventories 7,395 Restricted cash 4,682 Property and equipment, net 152,022 Customer contracts 8,121 Trade name 1,137 Developed technology 1,299 Goodwill 1,366 Investments 26,767 Other assets 7,482 Total assets acquired 318,315 Accounts payable 8,740 Accrued expenses and other current liabilities 44,136 Accrued income taxes 1,251 Current portion of long-term debt 8,140 Long-term debt 78,356 Pension liability 46,110 Deferred tax liability 709 Other liabilities 485 Total liabilities assumed 187,927 Enterprise value 130,388 Less fair value of noncontrolling interest 3,803 Purchase price attributable to controlling interest $ 126,585 The acquisition of GMSL resulted in goodwill of approximately $1.4 million . Goodwill was the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Goodwill was recognized as a new stand-alone reporting unit. Goodwill is not amortized and is not deductible for tax purposes.

The Existing Notes were issued at 99.05% of par, which resulted in a discount of $2.4 million . The net proceeds from the issuance of the Existing Notes were used to pay off the September Credit Facility entered into in connection with the GMSL acquisition. On March 26, 2015, the Company issued $50.0 million in aggregate principal amount of 11% Senior Secured Notes due 2019 (the “New Notes” and together with the Existing Notes, the “ 11% Notes). The New Notes were issued at 100.5% of par, plus accrued interest from November 20, 2014, which resulted in a premium of $0.3 million . The 11% Notes were issued under an indenture dated November 20, 2014, by and among HC2, the guarantors party thereto and U.S. Bank National Association, a national banking association (“U.S. Bank”), as trustee (the “ 11% Notes Indenture”). Maturity and Interest . The 11% Notes mature on December 1, 2019 . The 11% Notes accrue interest at a rate of 11% per year. Interest on the 11% Notes is paid semi-annually on December 1 and June 1 of each year. Ranking . The 11% Notes and the guarantees thereof will be HC2’s and certain of its direct and indirect domestic subsidiaries’ (the “Subsidiary Guarantors”) general senior secured obligations. The 11% Notes and the guarantees thereof will rank: (i) senior in right of payment to all of HC2’s and the Subsidiary Guarantors’ future subordinated debt; (ii) equal in right of payment with all of HC2’s and the Subsidiary Guarantors’ existing and future senior debt and effectively senior to all of its unsecured debt to the extent of the value of the collateral; and (iii) effectively subordinated to all liabilities of its non-guarantor subsidiaries. Collateral. The 11% Notes and the guarantees thereof will be collateralized on a first-priority basis by substantially all of HC2’s assets and the assets of the Subsidiary Guarantors (except for certain “Excluded Assets,” and subject to certain “Permitted Liens,” each as defined in the 11% Notes Indenture). The 11% Notes Indenture permits the Company, under specified circumstances, to incur additional debt in the future that could equally and ratably share in the collateral. The amount of such debt is limited by the covenants contained in the 11% Notes Indenture. Certain Covenants . The 11% Notes Indenture contains covenants limiting, among other things, the ability of HC2, and, in certain cases, HC2’s subsidiaries, to incur additional indebtedness; create liens; engage in sale-leaseback transactions; pay dividends or make distributions in respect of capital stock; make certain restricted payments; sell assets; engage in transactions with affiliates; or consolidate or merge with, or sell substantially all of its assets to, another person. These covenants are subject to a number of important exceptions and qualifications. HC2 is also required to maintain compliance with certain financial tests, including minimum liquidity and collateral coverage ratios. As of March 31, 2015, HC2 was in compliance with these covenants. Redemption Premiums . The Company may redeem the 11% Notes at a redemption price equal to 100% of the principal amount of the 11% Notes plus a make-whole premium before December 1, 2016. The make-whole premium is the greater of (i) 1% of principal amount or (ii) the excess of the present value of redemption price at December 1, 2016 plus all required interest payments through December 1, 2016 over the principal amount. After December 1, 2016, the Company may redeem the 11% Notes at a redemption price equal to 100% of the principal amount plus accrued interest. The Company is required to make an offer to purchase the 11% Notes upon a change of control. The purchase price will equal 101% of the principal amount of the 11% Notes on the date of purchase plus accrued interest. Terminated HC2 Credit Facilities In 2014, HC2 entered into (i) the May Credit Facility to finance a portion of the acquisition of Schuff, (ii) the Novatel Acquisition Term Loan to finance the acquisition of Novatel and (iii) the September Credit Facility to finance a portion of the acquisition of GMSL. HC2 used a portion of the proceeds from the September Credit Facility to repay the May Credit Facility and the Novatel Acquisition Term Loan. HC2 used the net proceeds from the issuance of the Existing Notes to repay the September Credit Facility. Prior to the payoff of the May Credit Facility, the Company made partial principal payments according to covenants within the agreement that required that portions of escrows received and proceeds from the exercise of warrants be used to pay down the May Credit Facility. In connection with those partial prepayments, the Company wrote off $0.1 million of deferred financing costs and $0.2 million of original issue discount in the second quarter of 2014 to amortization of debt discount. In connection with those partial prepayments, the Company wrote off $0.1 million of deferred financing costs and $1.9 million of original issue discount in the third quarter of 2014 to loss on early extinguishment or restructuring of debt. In connection with the payoff of the remaining balance of the May Credit Facility, the Company incurred $0.9 million of prepayment premiums and wrote off $0.3 million of deferred financing costs and $2.5 million of original issue discount in the third quarter of 2014 to loss on early extinguishment or restructuring of debt. In connection with the payoff of the Novatel Acquisition Term Loan, the Company wrote off $0.4 million of deferred financing costs and $0.8 million of original issue discount in the third quarter of 2014 to loss on early extinguishment or restructuring of debt.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Income Tax Benefit Income tax benefit was $6.0 million and $0 for the three months ended March 31, 2015 and 2014 , respectively. The tax provision benefit resulted primarily from the projected benefit as calculated under ASC 740 without applying a valuation allowance. The March 31, 2014 provision was under a full valuation allowance. NOL Limitation As of March 31, 2015, the Company had an estimated NOL carryforward in the amount of $62.7 million . This amount does not include 2015 activity. In the first quarter of 2014 , substantial acquisitions of HC2 stock were reported by new beneficial owners of 5% or more of the Company’s common stock on Schedule 13D filings made with the SEC. On May 29, 2014, the Company issued 30,000 shares of Series A Preferred Stock and 1,500,000 shares of common stock to finance the acquisition of Schuff. During the second quarter the Company completed a Section 382 review. The conclusions of this review indicate that an ownership change had occurred as of May 29, 2014. The Company’s annual Section 382 base limit following the ownership change is estimated to be $2.3 million per year. Unrecognized Tax Benefits The Company follows the provision of ASC No. 740-10, “Income Taxes” which prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that the Company has taken or expects to take on a tax return. The Company is subject to challenge from various taxing authorities relative to certain tax planning strategies, including certain intercompany transactions as well as regulatory taxes. The amount of unrecognized tax benefits may change in the next 12 months, however, the Company does not expect the change to have a significant impact on the results of operations or the financial position of the Company. Examinations The Company conducts business globally, and as a result, HC2 or one or more of its subsidiaries files income tax returns in the United States federal jurisdiction and various state and foreign jurisdictions. In the normal course of business the Company is subject to examination by taxing authorities throughout the world. The open tax years contain matters that could be subject to differing interpretations of applicable tax laws and regulations as they relate to the amount, character, timing or inclusion of revenue and expenses or the applicability of income tax credits for the relevant tax period. Given the nature of tax audits there is a risk that disputes may arise. Tax years 2002 - 2014 remain open for examination.

Litigation On November 6, 2014, a putative stockholder class action complaint challenging the buyout by HC2 Holdings, Inc. of the noncontrolling interest in Schuff International, Inc. (“Schuff International”) was filed in the Court of Chancery of the State of Delaware, captioned Mark Jacobs v. Philip A. Falcone, Keith M. Hladek, Paul Voigt, Michael R. Hill, Rustin Roach, D. Ronald Yagoda, Phillip O. Elbert, HC2 Holdings, Inc., and Schuff International, Inc. , Civil Action No. 10323 (the “Complaint”). On November 17, 2014 , a second lawsuit was filed in the Court of Chancery of the State of Delaware, captioned Arlen Diercks v. Schuff International, Inc. Philip A. Falcone, Keith M. Hladek, Paul Voigt, Michael R. Hill, Rustin Roach, D. Ronald Yagoda, Phillip O. Elbert, HC2 Holdings, Inc. , Civil Action No. 10359. The Complaints allege, among other things, that in connection with the buyout, the individual members of the Schuff International board of directors and HC2 Holdings, the controlling stockholder of Schuff, breached their fiduciary duties to members of the plaintiff class. The Complaints seek a rescission of the buyout and/or compensatory damages, as well as attorney’s fees and other relief. On February 19, 2015, the court consolidated the actions (now designated as Schuff International, Inc. Stockholders Litigation ) and appointed lead plaintiff and counsel. No responsive pleading has been filed yet by the defendants. We believe that the allegations and claims set forth in the Complaint are without merit and intend to defend them vigorously. On January 16, 2014, Xplornet Communications Inc. and Xplornet Broadband Inc. (“Xplornet”) instituted an action in the Ontario Superior Court of Justice styled Xplornet Communications Inc. and Xplornet Broadband Inc. vs. Inukshuk Wireless Inc., et al. Other defendants include Globility Communications Corporation (“Globility”), MIPPS Inc. (“MIPPS”), Primus Telecommunications Canada Inc. and the Company (sued under its previous name). In such action, Xplornet alleges that it entered into an agreement to acquire certain licenses for radio spectrum in Canada from Globility, a former subsidiary of the Company. Xplornet alleges that Globility agreed to sell Xplornet certain spectrum licenses in a Letter of Intent dated July 12, 2011 but then breached the Letter of Intent by selling the licenses to Inukshuk Wireless Inc. (“Inukshuk”) and that Globility further failed to negotiate with Xplornet in good faith. Xplornet also alleges that it reached an agreement with Inukshuk to purchase the licenses on June 26, 2012, but that Inukshuk breached that agreement by not completing the sale. Xplornet claims that, as a result of the foregoing, it has been damaged in the amount of $50 million . Xplornet also seeks injunctive relief against Inukshuk, pre and post-judgment interest, and costs. We intend to assert that we have meritorious defenses in the foregoing matter and we intend to defend ourselves vigorously. The Company is indemnifying Primus Telecommunications Canada, Inc., Globility, and MIPPS subject to a full reservation of rights pursuant to the Equity Purchase Agreement among PTUS, Inc., PTCAN, Inc. Primus Telecommunications Group, Incorporated, Primus Telecommunications Holding, Inc., Lingo Holdings, Inc. and Primus Telecommunications International, Inc. dated as of May 10, 2013 in connection with this case. On March 13, 2015, Inukshuk Wireless Partnership filed a cross claim against Globility, MIPPS, Primus Telecommunications Canada Inc., and the Company. Inukshuk asserts that if Inukshuk is found liable to Xplornet, then Inukshuk is entitled to contribution and indemnity, compensatory damages, interest, and costs from the Company. Inukshuk alleges that Globility represented and warranted that it owned the licenses at issue, that Globility held the licenses free and clear, and that no third party had any rights to acquire them. Inukshuk claims breach of contract and misrepresentation if the Court finds that any of these representations are untrue. We intend to assert that we have meritorious defenses to the cross claim and we intend to defend ourselves vigorously. The Company is subject to claims and legal proceedings that arise in the ordinary course of business. Such matters are inherently uncertain, and there can be no guarantee that the outcome of any such matter will be decided favorably to the Company or that the resolution of any such matter will not have a material adverse effect upon the Company’s business, consolidated financial position, results of operations or cash flow. The Company does not believe that any of such pending claims and legal proceedings will have a material adverse effect on its business, consolidated financial position, results of operations or cash flow. Tax Matters Currently, the Canada Revenue Agency (“CRA”) is auditing a subsidiary previously held by the Company. The Company intends to cooperate in audit matters. To date, CRA has not proposed any specific adjustments and the audit is ongoing.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION On April 11, 2014, HC2’s Board of Directors adopted the HC2 Holdings, Inc. 2014 Omnibus Equity Award Plan (the “Omnibus Plan”), which was approved by our stockholders at the annual meeting of stockholders held on June 12, 2014. The Omnibus Plan provides that no further awards will be granted pursuant to HC2’s Management Compensation Plan, as amended (the “Prior Plan”). However, awards that had been previously granted pursuant to the Prior Plan will continue to be subject to and governed by the terms of the Prior Plan. As of March 31, 2015, there were 469,871 shares of HC2 common stock underlying outstanding awards under the Prior Plan. The Compensation Committee (the “Committee”) of the Board of Directors of HC2 administers HC2’s Omnibus Plan and the Prior Plan and has broad authority to administer, construe and interpret the plans. The Omnibus Plan provides for the grant of awards of non-qualified stock options, incentive (qualified) stock options, stock appreciation rights, restricted stock awards, restricted stock units, other stock based awards, performance compensation awards (including cash bonus awards) or any combination of the foregoing. HC2 typically issues new shares of common stock upon the exercise of stock options, as opposed to using treasury shares. The Omnibus Plan authorizes the issuance of up to 5,000,000 shares of HC2 common stock, subject to adjustment as provided in the Omnibus Plan. The Company follows guidance which addresses the accounting for share-based payment transactions whereby an entity receives employee services in exchange for either equity instruments of the enterprise or liabilities that are based on the fair value of the enterprise’s equity instruments or that may be settled by the issuance of such equity instruments. The guidance generally requires that such transactions be accounted for using a fair-value based method and share-based compensation expense be recorded, based on the grant date fair value, estimated in accordance with the guidance, for all new and unvested stock awards that are ultimately expected to vest as the requisite service is rendered. There were 691,205 and 8,521 options granted during the three months ended March 31, 2015 and 2014, respectively. Of the 691,205 options granted during the three months ended March 31, 2015, 169,697 of such options were granted to Philip Falcone, pursuant to anti-dilution provisions of a standalone option agreement entered in connection with Mr. Falcone’s appointment as Chairman, President and Chief Executive Officer of HC2, and not pursuant to the Omnibus Plan. The weighted average fair value at date of grant for options granted during the three months ended March 31, 2015 was $3.16 per option. The fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions shown as a weighted average for the year: Three Months Ended March 31, 2015 2014 Expected option life 5.25 years 6 years Risk-free interest rate 1.49 - 1.68% 2.62 - 2.73% Expected volatility 36.29- 39.58% 37.20% Dividend yield —% —% Total share-based compensation expense recognized by the Company during the three months ended March 31, 2015 and 2014 was $2.7 million and $0.2 million , respectively. Most of HC2’s stock awards vest ratably during the vesting period. The Company recognizes compensation expense for equity awards, reduced by estimated forfeitures, using the straight-line basis. Restricted Stock A summary of HC2’s restricted stock activity during the three months ended March 31, 2015 is as follows: Shares Weighted Average Grant Date Fair Value Unvested - December 31, 2014 338,702 $ 4.26 Granted 1,436,281 $ 9.00 Vested (876,014 ) $ 8.99 Forfeitures — $ — Unvested - March 31, 2015 898,969 $ 7.23 As of March 31, 2015, the unvested restricted stock represented $5.7 million of compensation expense that is expected to be recognized over the weighted average remaining vesting period of 1.1 years. The number of shares of unvested restricted stock expected to vest is 898,969 . Stock Options A summary of HC2’s stock option activity during the three months ended March 31, 2015 is as follows: Shares Weighted Average Exercise Price Outstanding - December 31, 2014 3,573,141 $ 4.27 Granted 691,205 $ 8.82 Exercised — $ — Forfeitures (4,335 ) $ 2.79 Outstanding - March 31, 2015 4,260,011 $ 5.01 Eligible for exercise 1,576,470 $ 5.16 The following table summarizes the intrinsic values and remaining contractual terms of HC2’s stock options (in thousands): Intrinsic Value Weighted Average Remaining Life in Years Options outstanding - March 31, 2015 $ 26,000 9.4 Options exercisable - March 31, 2015 $ 9,388 9.3 During the three months ended March 31, 2015, the intrinsic value of the exercised options was $0 . As of March 31, 2015, the Company had 2,683,541 unvested stock options outstanding of which $3.2 million of compensation expense is expected to be recognized over the weighted average remaining vesting period of 1.2 years . The number of unvested stock options expected to vest is 2,683,541 shares, with a weighted average remaining life of 9.4 years , a weighted average exercise price of $5.01 , and an intrinsic value of $16.6 million .

EQUITY	EQUITY As of March 31, 2015 and December 31, 2014 , there were 25,369,260 and 23,813,085 shares of common stock outstanding, respectively. As of March 31, 2015 and December 31, 2014 , there were 54,500 and 41,000 shares of Preferred Stock outstanding, respectively. Preferred and Common Stock On May 29, 2014, HC2 issued 30,000 shares of Series A Preferred Stock and 1,500,000 shares of common stock, the proceeds of which were used to pay for a portion of the purchase price for the acquisition of Schuff. On September 22, 2014, HC2 issued 11,000 shares of Series A-1 Preferred Stock. Each share of Series A-1 Preferred Stock is convertible at a conversion price of $4.25 . In connection with the issuance of the Series A-1 Preferred Stock, HC2 amended the certificate of designation governing the Series A Preferred Stock on September 22, 2014, which changed the applicable conversion price from $4.25 to $4.00 , reflected the issuance of the Series A-1 Preferred Stock as a class of preferred stock which ranks at parity with the Series A Preferred Stock and made certain other changes to conform the terms of the Series A Preferred Stock to those of the Series A-1 Preferred Stock. On January 5, 2015, HC2 issued 14,000 shares of Series A-2 Convertible Participating Preferred Stock of HC2 (together with the Series A Preferred Stock and Series A-1 Preferred Stock, the “Preferred Stock”). Each share of Series A-2 Preferred Stock is convertible at a conversion price of $8.25 . In connection with the issuance of the Series A-2 Preferred Stock, HC2 amended the certificates of designation governing the Series A Preferred Stock and Series A-1 Preferred Stock on January 5, 2015, which reflected the issuance of the Series A-2 Preferred Stock as a class of preferred stock which ranks at parity with the Series A Preferred Stock and Series A-1 Preferred Stock and made certain other changes to conform the terms of the Series A Preferred Stock and Series A-1 Preferred Stock to those of the Series A-2 Preferred Stock. The conversion prices for the Preferred Stock are subject to adjustments for dividends, certain distributions, stock splits, combinations, reclassifications, reorganizations, mergers, recapitalizations and similar events. The Preferred Stock will accrue a cumulative quarterly cash dividend at an annualized rate of 7.5% . The accrued value of the Preferred Stock will accrete quarterly at an annualized rate of 4% that will be reduced to 2% or 0% if the Company achieves specified rates of growth measured by increases in its net asset value. The Company recorded a beneficial conversion feature on both of its Series A and Series A-1 Preferred Stock as a result of the fair market value of the Company’s common stock exceeding the conversion price. The Company recorded a $0.3 million beneficial conversion feature on its Series A-1 Preferred Stock which was calculated using the intrinsic value ( $4.36 — $4.25 ) multiplied by the number of convertible common shares ( $11,000,000 / $4.25 ). The Company recorded a $0.4 million beneficial conversion feature on its Series A Preferred Stock as a result of the adjustment to the conversion price from $4.25 to $4.00 . The beneficial conversion feature was calculated using the intrinsic value ( $4.05 — $4.00 ) multiplied by the number of convertible common shares ( $30,000,000 / $4.00 ). Each share of Preferred Stock may be converted by the holder into common stock at any time based on the then-applicable conversion price. On the seventh anniversary of the issue date of the Series A Preferred Stock, holders of the Preferred Stock shall be entitled to cause the Company to redeem the Preferred Stock at the accrued value per share plus accrued but unpaid dividends. Each share of Preferred Stock that is not so redeemed will be automatically converted into shares of common stock at the conversion price then in effect. Upon a change of control, holders of the Preferred Stock shall be entitled to cause HC2 to redeem their Preferred Stock at a price per share equal to the greater of (i) the accrued value of the Preferred Stock, which amount would be multiplied by 150% in the event of a change in control occurring on or prior to the third anniversary of the issue date of the Series A Preferred Stock plus and accrued but unpaid dividends and (ii) the value that would be received if the share of Preferred Stock were converted into common stock immediately prior to the change of control. At any time after the third anniversary of the issue date of the Series A Preferred Stock, HC2 may redeem the Preferred Stock, in whole but not in part, at a price per share generally equal to 150% of the accrued value per share plus accrued but unpaid dividends. After the third anniversary of the issue date of the Series A Preferred Stock, HC2 may force conversion of the Preferred Stock into common stock if the common stock’s thirty-day volume-weighted average price (“VWAP”) exceeds 150% of the then-applicable conversion price and the common stock’s daily VWAP exceeds 150% of the then-applicable conversion price for at least twenty trading days out of the thirty trading day period used to calculate the thirty-day VWAP. In the three months ended March 31, 2015, 500 shares of Series A-1 Preferred Stock were converted into 117,763 shares of common stock at the option of the holder. Dividends During 2015 , HC2’s Board of Directors declared cash dividends with respect to HC2’s issued and outstanding preferred stock, as presented in the following table (Total Dividend amount presented in thousands): Declaration Date March 31, 2015 Holders of Record Date March 31, 2015 Payment/Accrual Date April 15, 2015 Total Dividend $ 1,021

Risks and Uncertainties [Abstract]
BACKLOG	BACKLOG Schuff’s backlog was $306.1 million ( $253.3 million under contracts or purchase orders and $52.8 million under letters of intent) at March 31, 2015. Schuff’s backlog increases as contract commitments, letters of intent, notices to proceed and purchase orders are obtained, decreases as revenues are recognized and increases or decreases to reflect modifications in the work to be performed under the contracts, notices to proceed, letters of intent or purchase orders. Schuff’s backlog can be significantly affected by the receipt, or loss, of individual contracts. Approximately $172.4 million , representing 56.3% of Schuff’s backlog at March 31, 2015, was attributable to five contracts, letters of intent, notices to proceed or purchase orders. If one or more of these large contracts or other commitments are terminated or their scope reduced, Schuff’s backlog could decrease substantially.

The sale of Primus Telecommunications, Inc. (“PTI”) was also contemplated as part of this transaction but was deferred pending receipt of regulatory approval of such sale. The closing of the sale of PTI, which constituted the remainder of our North America Telecom segment, was completed on July 31, 2014 upon receipt of the necessary regulatory approval. The Company recorded a $13.8 million gain from the sale of this segment during the year ended December 31, 2013. In addition, the purchase agreement contains customary indemnification obligations, representations, warranties and covenants for a transaction of this nature. The Company received $126.0 million , net of $15.25 million held in escrow as part of the initial closing, with an additional $3.0 million held in escrow and paid upon closing of the sale of PTI. Pursuant to the terms of the purchase agreement, $6.45 million of the purchase price was placed in escrow to be released 14 months after the closing date, subject to any deductions required to satisfy indemnification obligations of HC2 under the purchase agreement, which amount was released to the Company in October 2014. In addition, $4.0 million of the purchase price was placed in escrow to cover any payments required in connection with the post-closing working capital and cash adjustments, of which $3.2 million was disbursed to the Company and $0.8 million was disbursed to York upon completion of such adjustments in February 2014. The $0.8 million was recorded as an adjustment to the gain that was recorded in 2013, which resulted in a net gain from this transaction of $13.0 million . Furthermore, $4.8 million of the purchase price was placed in escrow to cover certain tax liabilities, which escrow amount will be released after a positive ruling with respect to the underlying matter is received or 30 days after expiration of the applicable statute of limitations relating to the underlying matter. The $4.8 million escrow deposit is recorded in other assets in the condensed consolidated balance sheets, of which $0.4 million is reserved. Summarized operating results of the discontinued operations are as follows (in thousands): Three Months Ended March 31, 2015 2014 Net revenue $ — $ 3,278 Operating expenses 19 3,229 Income from operations (19 ) 49 Interest income and other income (expense) 4 (26 ) Loss before income tax (15 ) 23 Income tax benefit (expense) 6 (6 ) Income from discontinued operations $ (9 ) $ 17

Earnings Per Share [Abstract]
BASIC AND DILUTED INCOME (LOSS) PER COMMON SHARE	BASIC AND DILUTED INCOME (LOSS) PER COMMON SHARE Basic income (loss) per common share is calculated by dividing income (loss) attributable to common shareholders by the weighted average common shares outstanding during the period. Diluted income per common share adjusts basic income per common share for the effects of potentially dilutive common share equivalents. The Company had no dilutive common share equivalents during the three months ended March 31, 2015 and 2014 due to the results of operations being a loss from continuing operations, net of tax. For the three months ended March 31, 2015 and 2014 , the following were potentially dilutive but were excluded from the calculation of diluted loss per common share due to their antidilutive effect: Three months ended March 31, 2015 • 1.8 million shares issuable upon exercise of stock options and vesting of RSUs under the Prior Plan and Omnibus Plan. Three months ended March 31, 2014 • 0.3 million shares issuable upon exercise of stock options and vesting of RSUs under the Prior Plan; and • 18.6 million shares issuable upon exercise of Warrants. A calculation of basic income (loss) per common share to diluted income (loss) per common share is set forth below (in thousands, except per share amounts): Three Months Ended March 31, 2015 (As Restated) 2014 Loss from continuing operations attributable to HC2 Holdings, Inc. $ (6,316 ) $ (4,180 ) Income (loss) from discontinued operations (9 ) 17 Loss from sale of discontinued operations — (784 ) Net loss - basic $ (6,325 ) $ (4,947 ) Net loss - diluted $ (6,325 ) $ (4,947 ) Weighted average common shares outstanding-basic 24,146 14,631 Weighted average common shares outstanding-diluted 24,146 14,631 Basic loss per common share: Loss from continuing operations attributable to HC2 Holdings, Inc. $ (0.26 ) $ (0.29 ) Income (loss) from discontinued operations — — Loss from sale of discontinued operations — (0.05 ) Loss attributable to HC2 Holdings, Inc. $ (0.26 ) $ (0.34 ) Diluted loss per common share: Loss from continuing operations attributable to HC2 Holdings, Inc. $ (0.26 ) $ (0.29 ) Income (loss) from discontinued operations — — Loss from sale of discontinued operations — (0.05 ) Net loss attributable to HC2 Holdings, Inc. $ (0.26 ) $ (0.34 )

SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Purchase of United Teacher Associates Insurance Company and Continental General Insurance Company On April 13, 2015, the Company entered into a Stock Purchase Agreement with Continental General Corporation and Great American Financial Resources, Inc. (collectively, the “Sellers”), pursuant to which the Company agreed to purchase all of the issued and outstanding shares of common stock of United Teacher Associates Insurance Company and Continental General Insurance Company (collectively, the “Targets”), as well as all assets owned by the Sellers or their affiliates that are used exclusively or primarily in the business of the Targets, subject to certain exceptions. The consideration payable by the Company at closing is approximately $7 million , which amount will be increased or decreased by the amount by which the Targets’ adjusted capital and surplus exceeds or falls short of, respectively, an agreed-upon target capital and surplus amount (the “Closing Purchase Price”). The Closing Purchase Price will be paid in a mix of cash, debt and/or common stock of the Company, depending on the amount of the Closing Purchase Price. The Company also agreed to contribute to the Targets, at the closing, $13 million in cash or assets (the “Reserve Release Amount”), and to pay to the Sellers, on an annual basis with respect to the years 2015 through 2019, the amount, if any, by which the Targets’ cash flow testing and premium deficiency reserves decrease from the amount of such reserves as of December 31, 2014, up to the Reserve Release Amount. The transaction is expected to close during the third quarter of 2015, subject to receipt of required governmental approvals. Purchase of Convertible Debt of Gaming Nation Acquisition Corporation In April 2015, the Company invested CAD $20 million (or approximately $16 million ) in convertible debentures of Gaming Nation Acquisition Corporation. The convertible debentures, which have a maturity date of April 6, 2017 , are convertible into future shares of common stock, by the holder at various percentages that are dependent upon the timing of the conversion. The convertible debentures accrue interest at 6% which is compounded annually.

SUMMARY OF SIGNIFICANT ACCOUN27

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation —The accompanying unaudited Condensed Consolidated Financial Statements of HC2 have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial reporting and Securities and Exchange Commission (“SEC”) regulations. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such principles and regulations. In the opinion of management, the financial statements reflect all adjustments (all of which are of a normal and recurring nature), which are necessary to present fairly the financial position, results of operations, cash flows and comprehensive income (loss) for the interim periods. The results for the Company’s three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 . The financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in the Company’s most recently filed Annual Report on Form 10-K/A.
Principles of Consolidation	Principles of Consolidation —The Condensed Consolidated Financial Statements include the accounts of the Company, its wholly owned subsidiaries and all other subsidiaries over which the Company exerts control. All intercompany profits, transactions and balances have been eliminated in consolidation. As of March 31, 2015, the Company has a 97% interest in GMSL, a 91% interest in Schuff, a 51% interest in ANG and a 100% interest in DMi. Through its subsidiary, Pansend, the Company has an 80% interest in Genovel Orthopedics, Inc. and a 61% interest in R2 Dermatology (f/k/a “GemDerm Aesthetics, Inc.”). The results of each of these entities are consolidated with the Company’s results from and after their respective acquisition dates based on guidance from the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) No. 810, “Consolidation” (“ASC 810”). The remaining interests not owned by the Company are presented as a noncontrolling interest component of total equity. Schuff uses a 4-4-5 week quarterly cycle, which for the first quarter of 2015 ended on March 29, 2015.
Foreign Currency Transactions	Foreign Currency Transactions —Foreign currency transactions are transactions denominated in a currency other than a subsidiary’s functional currency. A change in the exchange rates between a subsidiary’s functional currency and the currency in which a transaction is denominated increases or decreases the expected amount of functional currency cash flows upon settlement of the transaction. That increase or decrease in expected functional currency cash flows is reported by the Company as a foreign currency transaction gain (loss).
Foreign Currency Translation	Foreign Currency Translation —The assets and liabilities of the Company’s foreign subsidiaries are translated at the exchange rates in effect on the reporting date. Income and expenses are translated at the average exchange rate during the period. The net effect of such translation gains and losses are reflected within accumulated other comprehensive income (loss) in the stockholders’ equity section of the condensed consolidated balance sheets.
Inventories	Inventories Schuff—Inventories, primarily steel components, are stated at the lower of cost or market under the first-in, first-out method. GMSL—Inventory is valued at the lower of cost or market value under the first-in first-out method. Provision for obsolescence is made where appropriate and is charged to cost of revenue in the condensed consolidated statements of operations. Short-term work in progress on contracts is stated at cost less foreseeable losses. These costs include only direct labor and expenses incurred to date and exclude any allocation of overhead. The policy for long-term work in progress contracts is disclosed within the Revenue and Cost Recognition accounting policy for GMSL.
Short-term Investments	Short-term Investments —The current investments are classified as available-for-sale securities and the change in value is recognized within accumulated other comprehensive income (loss).
Long-term Investments	Long-term Investments —Investments in non-wholly-owned companies are generally consolidated if the Company’s interest exceeds 50% or if the Company has the power to direct the economic activities of the entity and the obligation to absorb losses, or accounted for under the equity method of accounting when the Company exercises significant influence over the venture. Under the equity method of accounting, the Company records its proportionate interest in the underlying income or loss of the equity method investee. Additional investments made or distributions received are recorded as increases and decreases, respectively, to the carrying value of the equity method investment. Equity method investments are evaluated for potential impairment as circumstances warrant and an impairment charge is recorded when an impairment is deemed to be other-than-temporary. When the Company’s investment in an equity method investee is greater than its proportionate share of the underlying net assets of that investee, a basis difference is created under ASC No. 323, “Investments—Equity Method and Joint Ventures” (“ASC 323”). When this situation occurs, the Company is required to determine the acquisition date fair value of the identifiable assets and assumed liabilities in the same manner as for a business combination under ASC No. 805, “Business Combinations” (“ASC 805”). If the basis difference is assigned to amortizable assets, it is amortized (net of tax) against the Company’s investment in the equity method investee.
Property, Plant and Equipment	Property, Plant and Equipment —Property, plant and equipment are stated at cost less accumulated depreciation, which is provided on the straight-line method over the estimated useful lives of the assets. Cost includes major expenditures for improvements and replacements which extend useful lives or increase capacity of the assets as well as expenditures necessary to place assets into readiness for use. Cost includes the original purchase price of the asset and the costs attributable to bringing the asset to its working condition for its intended use. Cost includes finance costs incurred prior to the asset being available for use. Expenditures for maintenance and repairs are expensed as incurred. Depreciation is determined on a straight-line basis over the estimated useful lives of the assets, which range from 15 to 40 years for buildings and improvements, up to 35 years for cable-ships and submersibles, 3 to 15 years for machinery and equipment, and 3 to 20 years for plant and motor vehicles. Plant includes equipment on the cable-ships that is portable and can be moved around the fleet and computer equipment. Leasehold improvements are amortized over the lives of the leases or estimated useful lives of the assets, whichever is shorter. Assets under construction are not depreciated until they are complete and available for use. Costs for internal use software that are incurred in the preliminary project stage and in the post-implementation stage are expensed as incurred. Costs incurred during the application development stage are capitalized and amortized over the estimated useful life of the software. When assets are sold or otherwise retired, the costs and accumulated depreciation are removed from the books and the resulting gain or loss is included in operating results. Property, plant and equipment that have been included as part of the assets held for sale are no longer depreciated from the time that they are classified as such. The Company periodically evaluates the carrying value of its property, plant and equipment based upon the estimated cash flows to be generated by the related assets. If impairment is indicated, a loss is recognized.
Use of Estimates	Use of Estimates —The preparation of Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of net revenue and expenses during the reporting period. Actual results may differ from these estimates. Significant estimates include allowance for doubtful accounts receivable, the extent of progress towards completion on contracts, contract revenue and costs on long-term contracts, market assumptions used in estimating the fair values of certain assets and liabilities, the calculation used in determining the fair value of HC2’s stock options required by ASC No. 718, “Compensation—Stock Compensation” (“ASC 718”), income taxes and various other contingencies. Estimates of fair value represent the Company’s best estimates developed with the assistance of independent appraisals or various valuation techniques and, where the foregoing have not yet been completed or are not available, industry data and trends and by reference to relevant market rates and transactions. The estimates and assumptions are inherently subject to significant uncertainties and contingencies beyond the control of the Company. Accordingly, the Company cannot provide assurance that the estimates, assumptions, and values reflected in the valuations will be realized, and actual results could vary materially.
Revenue and Cost Recognition	Revenue and Cost Recognition GMSL —GMSL generates revenue by providing maintenance services for subsea telecommunications cabling. GMSL also generates revenue from the design and installation of subsea cables under contracts. GMSL also provides installation, maintenance and repair of fiber optic communication and power infrastructure to offshore oil and gas platforms and installs inter-array power cables for use in offshore wind farms and in the offshore wind market. Telecommunication/Maintenance—GMSL provides vessels on standby to repair fiber optic telecommunications cables in defined geographic zones, and its maintenance business is provided through contracts with consortia of up to 60 global telecommunications providers. Typically, GMSL enters into five to seven year contracts to provide maintenance to cable systems that are located in specific geographical areas. Revenue from these maintenance agreements is recognized on a straight line basis unless the pattern of costs associated with repairs indicates otherwise. Telecommunications/Installation—GMSL provides installation of cable systems including route planning, mapping, route engineering, cable laying, and trenching and burial. GMSL’s installation business is project-based with fixed price contracts typically lasting one to five months . Revenue is recognized as time and costs are incurred. Charter hire — rentals from short term operating leases in respect of vessels are recognized as revenue on a straight line basis over the term of the lease. Oil & Gas — GMSL provides installation, maintenance and repair of fiber optic communication and power infrastructure to offshore platforms. Its primary activities include providing power from shore, enabling fiber-based communication between platforms and shore-based systems and installing permanent reservoir monitoring systems which allow customers to monitor subsea seismic data. The majority of GMSL’s oil & gas business is contracted on a project-by-project basis with major energy producers or tier I engineering, procurement and construction (EPC) contractors. Revenue is recognized as time and costs are incurred. A loss is recognized immediately if the expected costs during any contract exceed expected revenues. Amounts billed in advance of revenue recognition are recorded as deferred revenue. Schuff —Schuff performs its services primarily under fixed-price contracts and recognizes revenues and costs from construction projects using the percentage of completion method. Under this method, revenue is recognized based upon either the ratio of the costs incurred to date to the total estimated costs to complete the project or the ratio of tons fabricated to date to total estimated tons. Revenue recognition begins when work has commenced. Costs include all direct material and labor costs related to contract performance, subcontractor costs, indirect labor, and fabrication plant overhead costs, which are charged to contract costs as incurred. Revenues relating to changes in the scope of a contract are recognized when the work has commenced, Schuff has made an estimate of the amount that is probable of being paid for the change and there is a high degree of probability that the charges will be approved by the customer or general contractor. At March 31, 2015, Schuff had $66.9 million of unapproved change orders on open projects, for which it has recognized revenues on a percentage of completion basis. While Schuff has been successful in having the majority of its change orders approved in prior years, there is no guarantee that the unapproved change orders at March 31, 2015 will be approved. Revisions in estimates during the course of contract work are reflected in the accounting period in which the facts requiring the revision become known. Provisions for estimated losses on uncompleted contracts are made in the period a loss on a contract becomes determinable. Construction contracts with customers generally provide that billings are to be made monthly in amounts which are commensurate with the extent of performance under the contracts. Contract receivables arise principally from the balance of amounts due on progress billings on jobs under construction. Retentions on contract receivables are amounts due on progress billings, which are withheld until the completed project has been accepted by the customer. Costs and recognized earnings in excess of billings on uncompleted contracts primarily represent revenue earned under the percentage of completion method which has not been billed. Billings in excess of related costs and recognized earnings on uncompleted contracts represent amounts billed on contracts in excess of the revenue allowed to be recognized under the percentage of completion method on those contracts. ICS —Net revenue is derived from carrying a mix of business, residential and carrier long-distance traffic, data and Internet traffic. For certain voice services, net revenue is earned based on the number of minutes during a call, and is recorded upon completion of a call. Revenue for a period is calculated from information received through the Company’s network switches. Customized software has been designed to track the information from the switch and analyze the call detail records against stored detailed information about revenue rates. This software provides the Company the ability to do a timely and accurate analysis of revenue earned in a period. Separate prepaid services software is used to track additional information related to prepaid service usage such as activation date, monthly usage amounts and expiration date. Revenue on these prepaid services is recognized as service is provided until expiration, when all unused minutes, which are no longer available to the customers, are recognized as revenue. Net revenue is also earned on a fixed monthly fee basis for unlimited local and long-distance voice plans and for the provision of data/Internet services (including retail VoIP), hosting, and colocation. In the United States, we charge customers Federal Universal Service Fund (“USF”) fees. We recognize revenue on a gross basis for USF and related fees. We record these fees as revenue when billed. Net revenue represents gross revenue, net of allowance for doubtful accounts receivable, service credits and service adjustments. Cost of revenue includes network costs that consist of access, transport and termination costs. The majority of the Company’s cost of revenue is variable, primarily based upon minutes of use, with transmission and termination costs being the most significant expense. Cost of revenue also includes fees such as Federal USF fees. Such costs are recognized when incurred in connection with the provision of telecommunications services.
Share-Based Compensation	Share-Based Compensation —The Company accounts for share-based compensation under ASC No. 718, “Compensation—Stock Compensation” (“ASC 718”), which addresses the accounting for share-based payment transactions whereby an entity receives employee services in exchange for equity instruments, including stock options and restricted stock units. ASC 718 generally requires that share-based compensation be accounted for using a fair-value based method. The Company records share-based compensation expense for all new and unvested stock options that are ultimately expected to vest as the requisite service is rendered. The Company issues new shares of common stock upon the exercise of stock options. The Company elected to adopt the alternative transition method for calculating the tax effects of share-based compensation. The alternative transition method includes simplified methods to determine the beginning balance of the additional paid in capital (“APIC”) pool related to the tax effects of share-based compensation and to determine the subsequent impact on the APIC pool and the statement of cash flows of the tax effects of share-based awards that were fully vested and outstanding upon the adoption of ASC 718. The Company uses a Black-Scholes option valuation model to determine the fair value of share-based compensation under ASC 718. The Black-Scholes model incorporates various assumptions including the expected term of awards, volatility of stock price, risk-free rates of return and dividend yield. The expected term of an award is no less than the option vesting period and is based on the Company’s historical experience. Expected volatility is based upon the historical volatility of the Company’s stock price. The risk-free interest rate is approximated using rates available on U.S. Treasury securities with a remaining term similar to the option’s expected life. The Company uses a dividend yield of zero in the Black-Scholes option valuation model as it does not anticipate paying cash dividends in the foreseeable future that do not contain antidilution provisions requiring the adjustment of exercise prices and option shares. Share-based compensation is recorded net of expected forfeitures.
Income (Loss) Per Common Share	Income (Loss) Per Common Share —Basic income (loss) per common share is computed using the weighted average number of shares of common stock outstanding during the period. Diluted income (loss) per common share is computed using the weighted average number of shares of common stock, adjusted for the dilutive effect of potential common stock and related income from continuing operations, net of tax. Potential common stock, computed using the treasury stock method or the if-converted method, includes options, restricted stock, restricted stock units and convertible preferred stock. In periods when the Company generates income, the Company calculates basic earnings per share using the two-class method, pursuant to ASC No. 260, “Earnings Per Share.” The two-class method is required as the shares of the Company’s Preferred Stock qualify as participating securities, having the right to receive dividends should dividends be declared on common stock. Under this method, earnings for the period are allocated on a pro-rata basis to the common stockholders and to the holders of preferred stock based on the weighted average number of common shares outstanding and the number of shares that could be converted. The Company does not use the two-class method in periods when it generates a loss as the holders of the Preferred Stock do not participate in losses.
Reclassification	Reclassification —Certain previous year amounts have been reclassified to conform with current year presentations, as related to the reporting of new balance sheet line items.
Newly Adopted Accounting Principles & New Accounting Pronouncements	Newly Adopted Accounting Principles In April 2014, an update was issued to the Presentation of Financial Statements Topic No. 205 and Property, Plant and Equipment Topic No. 360, ASU 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity”, which changes the criteria for reporting discontinued operations. The ASU revises the definition of a discontinued operation and expands the disclosure requirements. Entities should not apply the amendments to a component of an entity that is classified as held for sale before the effective date even if it is disposed of after the effective date. That is, the ASU must be adopted prospectively. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been previously reported in the financial statements. On January 1, 2015, the Company adopted this update, which did not have a material impact on the Condensed Consolidated Financial Statements. New Accounting Pronouncements In February 2015, the FASB issued ASU 2015-02, “Amendments to the Consolidation Analysis”, which amends the consolidation requirements in ASC 810 and significantly changes the consolidation analysis required under U.S. GAAP relating to whether or not to consolidate certain legal entities. Early adoption is permitted. The Company’s effective date for adoption is January 1, 2016. The Company does not expect this accounting update to have a material effect on its consolidated financial statements in future periods, although that could change. In January 2015, the FASB issued ASU 2015-01, “Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items”, which eliminates the concept from U.S. GAAP the concept of an extraordinary item. Under the ASU, an entity will no longer (1) segregate an extraordinary item from the results of ordinary operations; (2) separately present an extraordinary item on its income statement, net of tax, after income from continuing operations; or (3) disclose income taxes and earnings-per-share data applicable to an extraordinary item. Early adoption is permitted. The Company’s effective date for adoption is January 1, 2016. The Company does not expect this accounting update to have a material effect on its consolidated financial statements in future periods, although that could change.
