ORGANIZATION AND BUSINESS [Abstract]
ORGANIZATION AND BUSINESS	1. ORGANIZATION AND BUSINESS HC2 Holdings, Inc. (“HC2” and, together with its subsidiaries, the “Company”, “we” and “our”) is a diversified holding company which seeks to acquire and grow attractive businesses that we believe can generate long-term sustainable free cash flow and attractive returns. While the Company generally intends to acquire controlling equity interests in its operating subsidiaries, the Company may invest to a limited extent in a variety of debt instruments or minority equity interest positions. The Company’s shares of common stock trade on the NYSE MKT LLC under the symbol “HCHC”. The Company currently has six reportable segments based on management’s organization of the enterprise—Manufacturing, Marine Services, Utilities, Telecommunications, Life Sciences and Other, which includes operations that do not meet the separately reportable segment thresholds. Our Manufacturing segment includes Schuff International, Inc. (“Schuff”) and its wholly-owned subsidiaries, which primarily operate as integrated fabricators and erectors of structural steel and heavy steel plates with headquarters in Phoenix, Arizona. Schuff’s has operations in Arizona, Georgia, Texas, Kansas and California, with its construction projects primarily located in the aforementioned states. In addition, Schuff has construction projects in select international markets, primarily Panama through a Panamanian joint venture with Empresas Hopsa, S.A. that provides steel fabrication services. Our Marine Services segment includes Global Marine Systems Limited (“GMSL”). 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 at approximately 97%. Our Utilities segment includes American Natural Gas (“ANG”), which 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 vehicles. 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.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation Principles of Consolidation Reclassification 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, Accounting Standards Update (“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 May 2015, the FASB issued ASU 2015-08, “Business Combinations Topic No. 805: Pushdown Accounting-Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115 (SEC Update)”, which rescinds certain SEC guidance in order to confirm with ASU 2014-17, “Pushdown Accounting” (“ASU 2014-17”). ASU 2014-17 was issued in November 2014 and provides a reporting entity that is a business or nonprofit activity (an “acquiree”) the option to apply pushdown accounting to its separate financial statements when an acquirer obtains control of the acquiree. 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 April 2015, the FASB issued ASU 2015-03, “Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs”, which requires that debt issuance costs be reported in the balance sheet as a direct deduction from the face amount of the related liability, consistent with the presentation of debt discounts. Prior to the amendments, debt issuance costs were presented as a deferred charge (i.e., an asset) on the balance sheet. This ASU provides examples illustrating the balance sheet presentation of notes net of their related discounts and debt issuance costs. Further, the amendments require the amortization of debt issuance costs to be reported as interest expense. Similarly, debt issuance costs and any discount or premium are considered in the aggregate when determining the effective interest rate on the debt. 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 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	3. 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 “Business Combinations”, 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 of 2014 and first quarter of 2015, 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 815,843 shares and an increase in our ownership interest to 91%. The Company acquired Schuff to expand the business that it engages in and saw Schuff as an opportunity to enter the steel fabrication and erection market. The table below summarizes the 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 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 Property and equipment, net 85,662 Goodwill 24,490 Trade names 4,478 Other assets 2,947 Total assets acquired 293,978 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 Long-term debt 4,375 Deferred tax liability 7,693 Other liabilities 604 Noncontrolling interest 4,365 Total liabilities assumed 161,581 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 $24.5 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. Amortizable Intangible Assets The trade name was valued using a relief from royalty methodology. An estimated 60% of revenue is generated from Schuff’s relationship with general contractors. Thus, a value of the Schuff trade name was calculated based on the present value of Schuff’s projected revenues for 15 years multiplied by 60%. The trade name was valued at $4.5 million and is being amortized over a 15 year life. 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 six months ended June 30, 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 the Company has a controlling interest. The Company acquired ANG for its strong growth potential which is in line with the Company’s strategy to find businesses that it can operate to generate high returns and significant cash flow. The table below summarizes the preliminary estimate of fair value of the ANG assets acquired and liabilities assumed as of the acquisition date. The purchase price of ANG was valued at $17.7 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 we determined to be $2.2 million. The preliminary purchase price allocation 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 Total assets acquired 26,991 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 Fair value of net assets acquired 22,363 Less purchase price 15,500 Less fair value of noncontrolling interest 2,189 Excess of fair value of net assets over purchase price $ 4,674 The acquisition of ANG resulted in an excess of the fair value of the net assets acquired over the purchase price of $4.7 million. The Company does not believe that the circumstances surrounding the transaction give rise to a bargain purchase. The existing shareholders of ANG continue to manage the day-to-day operations and own the noncontrolling interest. Accordingly, due to the related party nature of the transaction, management has recorded the excess of the fair value of the assets acquired over the purchase price in additional paid-in capital. Amortizable Intangible Assets The trade name was valued using a relief from royalty methodology. The value of the ANG trade name was calculated based on ANG’s projected revenues for 10 years. An estimated royalty of 4% (looking at other market participants) was calculated net of tax based upon those revenues and present valued over 10 years. The trade name was preliminarily valued at $6.3 million and will be amortized over a 10 year life. value of the customer contracts ANG holds for its owned and operated facilities was calculated based on the present value of ANG’s net income from those contracts for 10 years. The customer contracts were preliminarily valued at $2.7 million and will be amortized over a 10 year life. GMSL On September 22, 2014, the Company completed the acquisition of Bridgehouse Marine Limited 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 preliminary purchase price allocation is as follows (in thousands): Cash and cash equivalents $ 62,555 Accounts receivable 26,183 Prepaid expenses and other current assets 9,886 Inventories 7,395 Restricted cash 4,682 Property and equipment, net 156,976 Customer contracts 7,796 Trade name 1,137 Developed technology 1,624 Investments 24,266 Other assets 7,482 Total assets acquired 309,982 Accounts payable 8,965 Accrued expenses and other current liabilities 34,767 Accrued income taxes 1,251 Current portion of long-term debt 8,140 Long-term debt 78,356 Pension liability 45,923 Deferred tax liability 1,013 Other liabilities 1,179 Total liabilities assumed 179,594 Enterprise value 130,388 Less fair value of noncontrolling interest 3,803 Purchase price attributable to controlling interest $ 126,585 The values for customer contracts, trade name, developed technology and investments are estimates and may change. Amortizable Intangible Assets ● Customer contracts were valued using a multi-period excess earnings methodology. Projected revenues and margins were used to forecast the earnings for each contract taking into consideration probabilities of contract renewals. Three customer contracts were preliminarily valued at £4.8 million ($7.8 million using the exchange rate in effect at the time of acquisition) and will be amortized over a 15 year life. ● The trade name was valued using a relief from royalty methodology. and will be amortized over a 3 year life. ● The developed technology was valued using a relief from royalty methodology. and will be amortized over a 4 year life. Investments (accounted for under the Equity Method) ● Sino British Submarine Systems (“SBSS”) – This investment was valued using an income approach (income capitalization method) and market approach (guideline public company method) and weighted each 50-50 to arrive at an operating value. From there, debt was added and a 35% ‘discount for the lack of marketability’ was applied to arrive at a fair value. That fair value was multiplied by GMSL’s ownership percentage to arrive a fair value applicable to GMSL. The income approach used year end 2014 results as acquisition-date financials as projections were not available. The multiples applied under the market approach were based on EBITDA and revenue multiples for entities operating in the same industry. The valuation resulted in a preliminary fair value of £10.4 million ($16.9 million using the exchange rate in effect at the time of acquisition). ● Huawei Marine Networks (“HMN”) – This investment was valued using a market approach (guideline public company method) and cost approach (book value of equity) and weighted each 50-50 to arrive at an operating value. There was no debt but a 30% ‘discount for the lack of marketability’ was applied to arrive at a fair value. That fair value was multiplied by GMSL’s ownership percentage to arrive a fair value applicable to GMSL. The multiples applied under the market approach were based on EBITDA and revenue multiples for entities operating in the same industry. The valuation resulted in a preliminary fair value of £4.3 million ($7.0 million using the exchange rate in effect at the time of acquisition). ● International Cableship (“ICPL”) – This investment was valued using a cost approach (book value of equity) to arrive at an operating value. There was no debt but a 20% ‘discount for the lack of marketability’ was applied to arrive at a fair value. That fair value was multiplied by GMSL’s ownership percentage to arrive a fair value applicable to GMSL. The valuation resulted in a preliminary fair value of £2.8 million ($4.5 million using the exchange rate in effect at the time of acquisition). ● Sembawang Cable Depot Pte Ltd (“SCDPL”) – This investment was valued using an income approach (income capitalization method) and market approach (guideline public company method) and weighted each 50-50 to arrive at an operating value. There was no debt, but a 20% ‘discount for the lack of marketability’ was applied to arrive at a fair value. That fair value was multiplied by GMSL’s ownership percentage to arrive a fair value applicable to GMSL. The income approach used year end 2014 results as acquisition-date financials as projections were not available. The multiples applied under the market approach were based on EBITDA and revenue multiples for entities operating in the same industry. The valuation resulted in a preliminary fair value of £0.7 million. ($1.1 million using the exchange rate in effect at the time of acquisition). ● Other investments were preliminarily valued at £0.3 million. ($0.5 million using the exchange rate in effect at the time of acquisition). The fair value was determined to approximate carrying value. ● Basis Differences – The total preliminary fair values of the named investments above was £18.2 million, while the carrying value (based on GMSL’s ownership percentage and using the balance sheets as of December 31, 2014) was £25.2 million. This resulted in a basis difference of £7.0 million ($11.4 million using the exchange rate in effect at the time of acquisition), of which the majority of was attributable to SBSS. This basis difference will be accreted up over a 10 year period which will result in the increase to the investment in SBSS.

INVESTMENTS	7. INVESTMENTS As of June 30, 2015, the Company had both short-term and long-term investments. The short-term investments are classified as available-for-sale securities and the change in value is recognized within accumulated other comprehensive income (loss). The fair market value is determined using quoted market prices (a Level I approach). See Note 14 – Fair Value of Financial Instruments for a description of Level I approach. The long-term investments are comprised of three types of investments; those accounted for under the equity method of accounting, investments in debt securities accounted for as available-for-sale securities and investment in debt securities accounted for under the cost method. For the debt securities, without quoted market prices, the fair values are calculated using other valuation methodologies (a Level II approach). During the three and six months ended June 30, 2015, the Company recorded $1.4 million and ($1.3) million, respectively, of its share of the equity method investments’ net income (loss).

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 a senior secured credit facility which provided 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”) that was 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 Ranking Collateral. Certain Covenants Redemption Premiums Terminated HC2 Credit Facilities In 2014, the Company entered into (i) a senior secured credit facility providing for an eighteen month, floating interest rate term loan of $80 million (the “May Credit Facility”) to finance a portion of the acquisition of Schuff, (ii) a senior unsecured credit facility consisting of a term loan of $17 million (the “Novatel Acquisition Term Loan”) for the purpose of acquiring an ownership interest in Novatel Wireless, Inc. and (iii) the September Credit Facility to finance a portion of the acquisition of GMSL. The Company used a portion of the proceeds from the September Credit Facility to repay the May Credit Facility and the Novatel Acquisition Term Loan. The Company 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. In connection with the payoff of the September Credit Facility, the Company wrote off $0.5 million of deferred financing costs and $4.5 million of original issue discount, which is net of a credit for previous paid funding fees of $2.3 million during the fourth quarter of 2014 to loss on early extinguishment or restructuring of debt. Schuff Credit Facilities Schuff has a Credit and Security Agreement (“Schuff Facility”) with Wells Fargo Credit, Inc. (“Wells Fargo”), pursuant to which Wells Fargo agreed to advance up to a maximum amount of $50.0 million to Schuff. On October 21, 2014, Schuff amended the Schuff Facility, pursuant to which Wells Fargo allowed for the issuance of a note payable up to $10.0 million, collateralized by its machinery and equipment (“Real Estate (2) Term Advance (M&E)”) and the issuance of a note payable up to $5.0 million, collateralized by its real estate (“Real Estate (2) Term Advance (Working Capital)”). At June 30, 2015 and December 31, 2014, Schuff had borrowed $11.7 million and $8.4 million, respectively, under the Real Estate (2) Term Advance (M&E) and Real Estate (2) Term Advance (Working Capital).

The Real Estate (2) Term Advance (M&E) and Real Estate (2) Term Advance (Working Capital) have a floating interest rate of LIBOR plus 4.0% and require monthly interest payments. On May 6, 2014, Schuff amended the Schuff Facility, pursuant to which Wells Fargo extended the maturity date of the Schuff Facility to April 30, 2019, lowered the interest rate charged in connection with borrowings under the line of credit and allowed for the issuance of a note payable totaling $5.0 million, collateralized by its real estate (“Real Estate Term Advance”). At June 30, 2015 and December 31, 2014, Schuff had borrowed $4.3 million and $4.6 million, respectively, under the Real Estate Term Advance. The Real Estate Term Advance has a 5 year amortization period requiring monthly principal payments and a final balloon payment at maturity. The Real Estate Term Advance has a floating interest rate of LIBOR plus 4.0% and requires monthly interest payments. The Schuff Facility has a floating interest rate of LIBOR plus 3.00% (3.27% at June 30, 2015) and requires monthly interest payments. As of June 30, 2015 and December 31, 2014, Schuff had no amounts outstanding under the Schuff Facility. The Schuff Facility is secured by a first priority, perfected security interest in all of Schuff’s assets, excluding the real estate, and its present and future subsidiaries and a second priority, perfected security interest in all of Schuff’s real estate. The security agreements pursuant to which Schuff’s assets are pledged prohibit any further pledge of such assets without the written consent of the bank. The Schuff Facility contains various restrictive covenants. At June 30, 2015, the Company was in compliance with these covenants. Schuff Hopsa Engineering, Inc. (“SHE”), a joint venture which Schuff consolidates, has a Line of Credit Agreement (“International LOC”) with Banco General, S.A. (“Banco General”) in Panama pursuant to which Banco General agreed to advance up to a maximum amount of $2.5 million.

INCOME TAXES [Abstract]
INCOME TAXES	10. INCOME TAXES Income Tax Benefit (Expense) Income tax expense was $2.5 million and $1.9 million for the three months ended June 30, 2015 and 2014, respectively. The tax expense resulted primarily from the projected expense as calculated under ASC 740 without applying a valuation allowance. The June 30, 2014 expense was due primarily to the acquisition of Schuff. Income tax benefit (expense) was $3.4 million and ($2.0) million for the six months ended June 30, 2015 and 2014, respectively. Due to circumstances that could lead to wide variability in the Effective Tax Rate, the Company did not use the Annual Effective Tax Rate (“ETR”) approach of ASC 740-270 (formerly FIN 18) to calculate its Q2 2015 interim tax provision. As such, the Q2 tax provision was calculated using a discrete year-to-date approach, by applying the statutory tax rate to the sum of the year-to-date loss plus non-deductible items. NOL Limitation As of June 30, 2015, the Company had an estimated NOL carryforward in the amount of $60.1 million. This amount does not include 2015 activity. In the first quarter of 2014, substantial acquisitions of the Company's 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 Convertible Participating Preferred Stock of the Company (the “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 $2.2 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, the Company 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.

SHARE-BASED COMPENSATION [Abstract]
SHARE-BASED COMPENSATION	12. SHARE-BASED COMPENSATION On April 11, 2014, the Company'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 the Company’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 June 30, 2015, there were 467,371 shares of the Company's common stock underlying outstanding awards under the Prior Plan. The Compensation Committee of the Board of Directors of the Company administers the Company’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. The Company 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 the Company's 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 1,577,385 options granted during the six months ended June 30, 2015 and 2014, respectively. Of the total options granted during the six months ended June 30, 2015 and 2014, 169,697 and 1,568,864, respectively, 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 the Company, and not pursuant to the Omnibus Plan. The weighted average fair value at date of grant for options granted during the six months ended June 30, 2015 and 2014 was $3.16 and $1.39, respectively, 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: Six Months Ended June 30, 2015 2014 Expected option life 5.25 years 6 years Risk-free interest rate 1.49-1.68 % 2.31 - 2.73 % Expected volatility 36.29-39.58 % 36.74% - 37.20 % Dividend yield 0 % 0 % Total share-based compensation expense recognized by the Company during the three months ended June 30, 2015 and 2014 was $2.4 million and $0.8 million, respectively. Total share-based compensation expense recognized by the Company during the six months ended June 30, 2015 and 2014 was $4.6 million and $1.0 million, respectively. Most of the Company's stock awards vest ratably during the vesting period. The Company recognizes compensation expense for equity awards using the straight-line basis. Restricted Stock A summary of the Company's restricted stock activity during the six months ended June 30, 2015 is as follows: Shares Weighted Average Grant Date Fair Value Unvested – December 31, 2014 338,702 $ 4.26 Granted 1,539,114 $ 9.14 Vested (977,753 ) $ 8.54 Forfeitures - $ - Unvested – June 30, 2015 900,063 $ 7.97 As of June 30, 2015, the unvested restricted stock represented $5.3 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 900,063. Stock Options A summary of the Company’s stock option activity during the six months ended June 30, 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 – June 30, 2015 4,260,011 $ 5.01 Eligible for exercise 2,126,747 $ 4.99 The following table summarizes the intrinsic values and remaining contractual terms of the Company’s stock options (in thousands): Intrinsic Value Weighted Average Remaining Life in Years Options outstanding – June 30, 2015 $ 15,674 9.2 Options exercisable – June 30, 2015 $ 7,669 9.0 During the six months ended June 30, 2015, the intrinsic value of the exercised options was $0. As of June 30, 2015, the Company had 2,133,264 unvested stock options outstanding of which $2.5 million of compensation expense is expected to be recognized over the weighted average remaining vesting period of 1.0 year. The number of unvested stock options expected to vest is 2,133,264 shares, with a weighted average remaining life of 9.2 years, a weighted average exercise price of $5.01, and an intrinsic value of $15.7 million.

EQUITY [Abstract]
EQUITY	13. EQUITY As of June 30, 2015 and December 31, 2014, there were 25,592,356 and 23,813,085 shares of common stock outstanding, respectively. As of June 30, 2015 and December 31, 2014, there were 54,000 and 41,000 shares of Preferred Stock outstanding, respectively. Preferred and Common Stock On May 29, 2014, the Company 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, the Company issued 11,000 shares of Series A-1 Convertible Participating Preferred Stock of the Company (the “Series A-1 Preferred Stock”). Each share of Series A-1 Preferred Stock is convertible at a conversion price of $4.25. On January 5, 2015, the Company issued 14,000 shares of Series A-2 Convertible Participating Preferred Stock of the Company (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, the Company 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 its 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). 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 the Company 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. The certificates of amendment related to the Company’s Preferred Stock (the “Prior Amendment”) did not become effective because they were filed without proper authorization of the stockholders of the Company. The holders of the Series A Preferred Stock have agreed to release all claims against the Company relating to the ineffectiveness of the Prior Amendments, including the fact that the conversion price of the Series A Preferred Stock remains at $4.25. The release of claims was granted as payment in full of the purchase price of the $5.0 million of Notes issued to the holders of the Series A Preferred Stock. The Company recorded this payment to other income (expense), net. See Note 20, “Subsequent Events” for additional information surrounding this transaction At any time after the third anniversary of the issue date of the Series A Preferred Stock, the Company 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, the Company 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 six months ended June 30, 2015, 1,000 shares of Series A-1 Preferred Stock were converted into 235,526 shares of common stock at the option of the holder. Dividends During 2015, the Company's Board of Directors declared cash dividends with respect to the Company’s issued and outstanding preferred stock, as presented in the following table (Total Dividend amount presented in thousands): Declaration Date March 31, 2015 June 30, 2015 Holders of Record Date March 31, 2015 June 30, 2015 Payment/Accrual Date April 15, 2015 July 15, 2015 Total Dividend $ 1,021 $ 1,020

FAIR VALUE OF FINANCIAL INSTRUM

FAIR VALUE OF FINANCIAL INSTRUMENTS	6 Months Ended

FAIR VALUE OF FINANCIAL INSTRUMENTS [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	14. FAIR VALUE OF FINANCIAL INSTRUMENTS U.S. GAAP establishes a hierarchical disclosure framework which prioritizes and ranks the level of market price observability used in measuring financial instruments at fair value. Market price observability is affected by a number of factors, including the type of financial instrument, the characteristics specific to the financial instrument and the state of the marketplace, including the existence and transparency of transactions between market participants. Financial instruments with readily available quoted prices in active markets generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. Financial instruments measured and reported at fair value are classified and disclosed based on the observability of inputs used in the determination of fair values, as follows: ● Level I — Quoted prices are available in active markets for identical financial instruments as of the reporting date. The type of financial instruments in Level I include listed equities. Under U.S. GAAP, the Company does not adjust the quoted price for these investments, even in situations where the Company holds a large position and a sale could reasonably impact the quoted price. ● Level II — Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined through the use of models or other valuation methodologies. Financial instruments which are generally included in this category include long-term debt. ● Level III — Pricing inputs are unobservable for the financial instruments and includes situations where there is little, if any, market activity for the financial instrument. The inputs into the determination of fair value require significant management judgment or estimation. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the determination of which category within the fair value hierarchy is appropriate for any given financial instrument is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument. There were no transfers between levels of the fair value hierarchy during the six months ended June 30, 2015. The carrying amounts reported in the condensed consolidated balance sheets for cash and cash equivalents, accounts receivable, costs and recognized earnings in excess of billings, accounts payable, accrued expenses, billings in excess of costs and recognized earnings, and other current assets and liabilities approximate fair value due to relatively short periods to maturity. The Company’s investments in available-for-sale securities, recorded at fair value using quoted market prices (a Level I approach), as of June 30, 2015 and December 31, 2014 was $12.3 million and $4.9 million, respectively. The Company’s investments in available-for-sale securities, recorded using other valuation methodologies (a Level II approach), as of June 30, 2015 and December 31, 2014 was $16.1 million and $0, respectively. The estimated aggregate fair value of the Company’s debt, based on significant other observable inputs (a Level II approach) approximated $387.8 million and $338.1 million at June 30, 2015 and December 31, 2014, respectively.

BACKLOG	17. BACKLOG Schuff’s backlog was $329.3 million ($251.0 million under contracts or purchase orders and $78.3 million under letters of intent) at June 30, 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 $143.9 million, representing 43.7% of Schuff’s backlog at June 30, 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.

DISCONTINUED OPERATIONS [Abstract]
DISCONTINUED OPERATIONS	18. DISCONTINUED OPERATIONS On July 31, 2013, the Company completed the sale of Lingo, Inc., iPrimus, USA, Inc., 3620212 Canada Inc., Primus Telecommunications Canada, Telesonic Communications Inc., and Globility Communications Corporation to affiliates of York Capital Management, an investment firm (together “York”), for $129 million. 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 the Company 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 June 30, Six Months Ended June 30, 2015 2014 2015 2014 Net revenue $ - $ 3,190 $ - $ 6,468 Operating expenses 18 3,113 37 6,342 Income (loss) from operations (18 ) 77 (37 ) 126 Interest expense - (3 ) - (3 ) Interest income and other income (expense) - (25 ) 4 (51 ) Income (loss) before income tax (18 ) 49 (33 ) 72 Income tax benefit (expense) 7 (22 ) 13 (28 ) Income (loss) from discontinued operations $ (11 ) $ 27 $ (20 ) $ 44

BASIC AND DILUTED INCOME (LOSS) PER COMMON SHARE [Abstract]
BASIC AND DILUTED INCOME (LOSS) PER COMMON SHARE	19. 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 and six months ended June 30, 2015 and 2014 due to the results of operations being a loss from continuing operations, net of tax. For the three and six months ended June 30, 2015, the Company had Preferred Stock, as well as outstanding stock options and unvested RSUs granted under the Prior Plan and Omnibus Plan that were potentially dilutive but were excluded from the calculation of diluted loss per common share due to their antidilutive effect. For the three and six months ended June 30, 2014, the Company had outstanding stock options and unvested RSUs granted under the Prior Plan as well as certain warrants that were potentially dilutive but were excluded from the calculation of diluted loss per common share due to their antidilutive effect. 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 June 30, Six Months Ended June 30, 2015 2014 2015 2014 Loss from continuing operations attributable to HC2 Holdings, Inc. $ (12,294 ) $ (3,788 ) $ (18,434 ) $ (7,968 ) Income (loss) from discontinued operations (11 ) 27 (20 ) 44 Loss from sale of discontinued operations - - - (784 ) Net loss - basic $ (12,305 ) $ (3,761 ) $ (18,454 ) $ (8,708 ) Net loss - diluted $ (12,305 ) $ (3,761 ) $ (18,454 ) $ (8,708 ) Weighted average common shares outstanding-basic 25,514 16,905 24,838 15,780 Weighted average common shares outstanding-diluted 25,514 16,905 24,838 15,780 Basic loss per common share: Loss from continuing operations attributable to HC2 Holdings, Inc. $ (0.48 ) $ (0.22 ) $ (0.74 ) $ (0.50 ) Income (loss) from discontinued operations - - - - Loss from sale of discontinued operations - - - (0.05 ) Loss attributable to HC2 Holdings, Inc. $ (0.48 ) $ (0.22 ) $ (0.74 ) $ (0.55 ) Diluted loss per common share: Loss from continuing operations attributable to HC2 Holdings, Inc. $ (0.48 ) $ (0.22 ) $ (0.74 ) $ (0.50 ) Income (loss) from discontinued operations - - - - Loss from sale of discontinued operations - - - (0.05 ) Net loss attributable to HC2 Holdings, Inc. $ (0.48 ) $ (0.22 ) $ (0.74 ) $ (0.55 )

SUBSEQUENT EVENTS [Abstract]
SUBSEQUENT EVENTS	20. SUBSEQUENT EVENTS On August 5, 2015, the Company issued $5.0 million aggregate principal amount of its 11% Senior Secured Notes due 2019 (the “Additional 11% Notes”). The Additional 11% Notes will mature on December 1, 2019. The purchasers paid for the Additional 11% Notes by granting the release of claims more fully described below. The certificates of amendment related to the Company’s Preferred Stock (the “Prior Amendment”) did not become effective because they were filed without proper authorization of the stockholders of the Company. The holders of the Series A Preferred Stock have agreed to release all claims against the Company relating to the ineffectiveness of the Prior Amendments, including the fact that the conversion price of the Series A Preferred Stock remains at $4.25. The release of claims was granted as payment in full of the purchase price of the $5.0 million of Notes issued to the holders of the Series A Preferred Stock. The Additional 11% Notes were issued pursuant to the 11% Notes Indenture, by and among the Company, the guarantors party thereto and U.S. Bank National Association, as trustee. The Company previously issued $300 million aggregate principal amount of 11% Notes pursuant to the 11% Notes Indenture in connection with two prior offerings. The Additional 11% Notes constitute part of a single class of securities with the 11% Notes and have the same terms as the 11% Notes, other than issue date.

Newly Adopted Accounting Principles	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, Accounting Standards Update (“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 May 2015, the FASB issued ASU 2015-08, “Business Combinations Topic No. 805: Pushdown Accounting-Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115 (SEC Update)”, which rescinds certain SEC guidance in order to confirm with ASU 2014-17, “Pushdown Accounting” (“ASU 2014-17”). ASU 2014-17 was issued in November 2014 and provides a reporting entity that is a business or nonprofit activity (an “acquiree”) the option to apply pushdown accounting to its separate financial statements when an acquirer obtains control of the acquiree. 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 April 2015, the FASB issued ASU 2015-03, “Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs”, which requires that debt issuance costs be reported in the balance sheet as a direct deduction from the face amount of the related liability, consistent with the presentation of debt discounts. Prior to the amendments, debt issuance costs were presented as a deferred charge (i.e., an asset) on the balance sheet. This ASU provides examples illustrating the balance sheet presentation of notes net of their related discounts and debt issuance costs. Further, the amendments require the amortization of debt issuance costs to be reported as interest expense. Similarly, debt issuance costs and any discount or premium are considered in the aggregate when determining the effective interest rate on the debt. 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 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.
