ORGANIZATION AND BUSINESS	Sep. 30, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND BUSINESS	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 noncontrolling 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 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 our acquisition of GMSL, 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 service operators and Internet service providers from our International Carrier Services (“ICS”) business unit. In our Life Sciences segment, we operate Pansend Life Sciences, LLC (“Pansend”, f/k/a Pansend, LLC), which has a 77% 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 August 2015, the Company purchased 180,415 shares of MediBeacon, Inc., Preferred Stock for $2.9 million for a total ownership of approximately 9%. In February 2015, the Company sold 586,095 shares of Novatel Wireless, Inc. (“Novatel”) common stock and a warrant to purchase 293,047 shares of Novatel's common stock for $1.0 million which resulted in a gain of $0.2 million. In March 2015, the Company exercised a warrant to purchase 3,824,600 shares of Novatel's common stock for $8.6 million and also acquired a new warrant to purchase 1,593,583 shares of Novatel's common stock at $5.50 per share. The Company’s ownership increased to approximately 23% of Novatel’s common stock. A basis difference, net of tax for the additional investment in March 2015, of $5.6 million consists of a trade name of $0.6 million (amortized over 15 years), a technology and customer intangible of $0.8 million (amortized over 7 years) and goodwill of $4.2 million. In the first quarter of 2015, the Company purchased $3.0 million of convertible debt of DTV America Corporation (“DTV”) in aggregate. The convertible debt earned 10% interest. In addition, the Company acquired share purchase warrants, which are exercisable for 666,667 and 333,333 DTV's common shares until January 20, 2018 and March 6, 2018, respectively, at an exercise price of $2.00 per share. The principal balance and accrued interest of the convertible debt was automatically converted into 2,081,693 shares of common stock on June 30, 2015. In April 2015, the Company purchased a $16.1 million convertible debenture (the "Debenture") of Gaming Nation, Inc. ("Gaming Nation"). The Debenture earns 6% interest in-kind and the principal and interest is convertible at the Company's option into Gaming Nation's common shares at a conversion price of $2.25. On June 9, 2015, the Debenture became convertible into 8,888,889 of Gaming Nation's common shares until June 9, 2017. In addition, the Company acquired a share purchase warrant, which is exercisable for 28,126,068 of Gaming Nation's common shares until April 6, 2020 at varying exercise prices, commencing at $5.00 per share for the first 2 years. For the quarter ended September 30, 2015, the Company recorded a foreign currency translation loss of $1.2 million and unrealized loss on fair value of the Debenture of $2.6 million within other comprehensive income.

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 third quarter of 2015 ended on September 27, 2015. Reclassification - Certain previous year amounts have been reclassified to conform with current year presentations 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, Accounting Standards Update (“ASU”) 2014-8, “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 September 2015, the FASB issued ASU 2015-16, “Business Combination Topic No. 805: Simplifying the Accounting for Measurement - Period Adjustments”, which requires adjustments to provisional amounts that are identified during the measurement period to be recognized in the reporting period in which the adjustment amounts are determined. This includes any effect on earnings of changes in depreciation, amortization, or other income effects as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. 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 August 2015, the FASB issued ASU 2015-15, “Interest - Imputation of Interest Subtopic No. 835-30: Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements”, which codifies an SEC staff announcement that entities are permitted to defer and present debt issuance costs related to line-of-credit arrangements as assets. 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 August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers Topic No. 606: Deferral of the Effective Date”, which defers the effective date of the new revenue recognition standard by one year. Early adoption is permitted. The Company’s effective date for adoption is January 1, 2018. 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 July 2015, the FASB issued ASU 2015-11, “Inventory Topic No. 330: Simplifying the Measurement of Inventory”, which requires inventory within the scope of the ASU to be measured using the lower of cost and net realizable value. Inventory excluded from the scope of the ASU will continue to be measured at the lower of cost or market. Early adoption is permitted. The Company’s effective date for adoption is January 1, 2017. 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 May 2015, the FASB issued ASU 2015-8, “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 2015-3, “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 2015-2, “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 2015-1, “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

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 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 the nine months ended September 30, 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 our acquisition of an additional 816,414 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 $78.8 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 Schuff trade name was valued using a relief from royalty methodology. An estimated 60% of Schuff's 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 Schuff 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 of Schuff to 91% from the May 2014 acquisition date through December 31, 2014, the Company recorded an adjustment to Schuff’s noncontrolling interest of $3.4 million and recorded as the excess book value over the fair value of purchased noncontrolling interest in the Company’s condensed consolidated statement of stockholders’ equity. In the nine months ended September 30, 2015, the Company acquired an additional 7,371 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 was 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 fair values 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 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	3,349
Total liabilities assumed	4,447
Fair value of net assets acquired	22,544



Less purchase price	15,500
Less fair value of noncontrolling interest	2,189
Excess of fair value of net assets over purchase price	$	4,855

The acquisition of ANG resulted in an excess of the fair value of the net assets acquired over the purchase price of $4.9 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 ANG 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 ANG trade name was valued at $6.3 million and is being amortized over a 10 year life. Customer contracts were valued using a multi-period excess earnings methodology. The 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 valued at $2.7 million and is being 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 fair values of the GMSL assets acquired and liabilities assumed as of the acquisition date. The net enterprise value of GMSL was valued at $130 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 is as follows (in thousands):



Cash and cash equivalents	$	62,555
Accounts receivable	26,183
Prepaid expenses and other current assets	22,111
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	493
Investments	28,876
Other assets	7,482
Total assets acquired	322,356
Accounts payable	8,965
Accrued expenses and other current liabilities	46,992
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	1,163
Other liabilities	1,178
Total liabilities assumed	191,968
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 $0.5 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.

After the June 30, 2015 financial statements were issued, we updated certain balance sheet items under the purchase price allocation. The carrying value of the property and equipment, net was reduced by $5.0 million, the carrying value of the investments was increased by $4.6 million and a deferred tax liability of $0.1 million was established on the developed technology intangible asset. These increases and decreases resulted in the creation of $0.5 million of goodwill.

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 valued at £5.0 million ($8.1 million using the exchange rate in effect at the time of acquisition) and are being amortized over a 15 year life.

•

The GMSL trade name was valued using a relief from royalty methodology. Given an element of uncertainty surrounding the GMSL trade name, and consistent with likely market participant use, a probability of continuing use was applied to the projected revenue stream. The GMSL trade name was valued at £0.7 million ($1.1 million using the exchange rate in effect at the time of acquisition) and is being amortized over a 3 year life.

•

The developed technology was valued using a relief from royalty methodology. The fair value was estimated based on the revenue attributable to developed technology and the hypothetical royalties avoided by owning the technology as well as the current royalties earned, the revenue stream was adjusted for technology obsolescence, as the technology will decay over time and be replaced by new technologies. The developed technology was preliminarily valued £0.8 million ($1.3 million using the exchange rate in effect at the time of acquisition) and is being amortized over a 4 year life.

GMSL's Joint Ventures (accounted for under the Equity Method)

•

S. B. Submarine Systems Co., Ltd. (“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 fair value of £9.7 million ($15.8 million using the exchange rate in effect at the time of acquisition).

•

Huawei Marine Networks Co., Ltd. – 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 fair value of £4.3 million ($7.0 million using the exchange rate in effect at the time of acquisition).

•

International Cableship Pte., Ltd. – 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 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. – 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 fair value of £0.7 million. ($1.1 million using the exchange rate in effect at the time of acquisition).


•	Other investments were 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 fair values of the named investments above was £17.5 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 £7.7 million ($12.5 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 9 year period which will result in the increase to the investment in SBSS.

11% Senior Secured Notes due 2019

On November 20, 2014, the Company issued $250.0 million in aggregate principal amount of 11% Senior Secured Notes due 2019 (the “Existing Notes”). 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 an additional $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. On August 5, 2015, the Company issued an additional $5.0 million aggregate principal amount of its 11% Senior Secured Notes due 2019 (the “Additional 11% Notes” and together with the New Notes and the Existing Notes, the “11% Notes”). The purchasers paid for the Additional 11% Notes by granting a claims release (see Note 13 "Equity" for additional information). 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 1st and June 1st 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 September 30, 2015, HC2 was in compliance with these covenants.

Redemption Premiums. The Company may redeem the 11% Notes at a redemption price equal to 100.0% 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 at a purchase price equal to 101% of the principal amount of the 11% Notes on the date of purchase plus accrued interest.

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 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 September 30, 2015 and December 31, 2014, Schuff had borrowed $11.0 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 5 year amortization period requiring monthly principal payments and a final balloon payment at maturity. 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 September 30, 2015 and December 31, 2014, Schuff had borrowed $4.2 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 3.0% (3.32% at September 30, 2015) and requires monthly interest payments. As of September 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 September 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. The line of credit is secured by a first priority, perfected security interest in the SHE’s property and plant. The interest rate is 5.25% plus 1% of the special interest compensation fund (“FECI”). The line of credit contains covenants that, among other things, limit the SHE’s ability to incur additional indebtedness, change its business, merge, consolidate or dissolve and sell, lease, exchange or otherwise dispose of its assets, without prior written notice.

There was $3.9 million in outstanding letters of credit issued and $46.1 million available under the Schuff Facility at September 30, 2015. At September 30, 2015, Schuff had $2.0 million in borrowings and no outstanding letters of credit issued under its International LOC. There was $0.5 million available under Schuff’s International LOC at September 30, 2015.

GMSL Credit Facility

GMSL established a $20.0 million term loan with DVB Bank in January 2014 (the “GMSL Facility”). This GMSL facility has a 4.5 year term and bears interest at the rate of 3.65% plus the USD LIBOR rate. As of September 30, 2015 and December 31, 2014, $13.4 million and $16.7 million, respectively, remained outstanding under the GMSL Facility. The GMSL Facility contains various restrictive covenants. At September 30, 2015, GMSL was in compliance with these covenants.

ANG Term Loan

ANG established a term loan with Signature Financial in October 2013. This term loan has a 5 year term and bears interest at the rate of 5.5%. As of September 30, 2015 and December 31, 2014, $0.7 million and $0.8 million, respectively, remained outstanding under this term loan.

GMSL Capital Leases

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Income Tax Benefit (Expense) Income tax was a benefit of $0.6 million and an expense of $4.5 million for the three months ended September 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 September 30, 2014 expense was due primarily to the acquisition of Schuff. Income tax was a benefit $4.0 million and an expense of $6.5 million for the nine months ended September 30, 2015 and 2014, respectively. The Company used the Annual Effective Tax Rate (“ETR”) approach of ASC 740-270 (formerly FIN 18) to calculate its third quarter 2015 interim tax provision. NOL Limitation As of September 30, 2015, the Company had an estimated NOL carryforward in the amount of $61.1 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.

COMMITMENTS AND CONTINGENCIES	9 Months Ended
COMMITMENTS AND CONTINGENCIES	Sep. 30, 2015
Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Litigation 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 consolidated financial statements. The Company does not believe that any of such pending claims and legal proceedings will have a material adverse effect on its consolidated financial statements. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in a liability and the amounts of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss to the extent necessary for the consolidated financial statements not to be misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements. On November 6, 2014, a putative stockholder class action complaint challenging the tender offer by which HC2 acquired approximately 721,000 of the issued and outstanding common shares of Schuff 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. On February 19, 2015, the court consolidated the actions (now designated as Schuff International, Inc. Stockholders Litigation) and appointed lead plaintiff and counsel. The currently operative complaint is the November 6, 2014 Complaint filed by Mark Jacobs. The Complaint alleges, among other things, that in connection with the tender offer, the individual members of the Schuff board of directors and HC2, the controlling stockholder of Schuff, breached their fiduciary duties to members of the plaintiff class. The Complaint also purports to challenge a potential short-form merger based upon plaintiff’s expectation that the Company would cash out the remaining public stockholders of Schuff International following the completion of the tender offer. Such a short-form merger has never been formally proposed or acted upon and as of September 30, 2015, approximately 341 thousand shares of Schuff remain in public hands, representing approximately 9% of the outstanding shares of Schuff. The Complaint seeks rescission of the tender offer and/or compensatory damages, as well as attorney’s fees and other relief. The defendants filed answers to the Complaint on July 30, 2015. Defendants are currently preparing for the discovery phase of the case. We believe that the allegations and claims set forth in the Complaint are without merit and intend to defend them vigorously. On July 16, 2013, Plaintiffs Xplornet Communications Inc. and Xplornet Broadband, Inc. (“Xplornet”) initiated an action against Inukshuk Wireless Inc. (“Inukshuk”), Globility Communications Corporation (“Globility”), MIPPS Inc., Primus Telecommunications Canada Inc. ("PTCI") and Primus Telecommunications Group, Incorporated (n/k/a HC2)("PTGi"). Xplornet alleges that it entered into an agreement to acquire certain licenses for radio spectrum in Canada from Globility. 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. Xplornet then alleges that they 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 alleges that, as a result of the foregoing, they have been damaged in the amount of $50 million. On January 29, 2014, Globility, MIPPS Inc., and PTCI, demanded indemnification pursuant to the Equity Purchase Agreement among PTUS, Inc., PTCAN, Inc., PTGi, Primus Telecommunications Holding, Inc., Lingo Holdings, Inc., and Primus Telecommunications International, Inc., dated as of May 10, 2013. On February 14, 2014, the Company assumed the defense of this litigation, while reserving all of its rights under the Equity Purchase Agreement. On February 5, 2014, Globility, MIPPS Inc., and PTCI filed a Notice of Intent to Defend. On February 18, 2014, Globility, MIPPS Inc., and PTCI filed a Demand for Particulars. A Notice of Change of Solicitors to Hunt Partners LLP was filed on behalf of those same entities on April 1, 2014. On March 13, 2015, Inukshuk filed a cross claim against Globility, MIPPS, PTCI, and PTGi. 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. On October 17, 2014, the Company moved for summary judgment against Xplornet arguing that there was no agreement between Globility and Xplornet to acquire the licenses at issue. On June 5, 2015, Inukshuk also moved for summary judgment against Xplornet, similarly arguing that there was no agreement between Inukshuk and Xplornet to acquire the licenses in question. On September 17, 2015, Xplornet amended its claim to change its theory from breach of a written letter of intent allegedly accepted on July 12, 2011 to breach of an oral agreement allegedly entered on July 7, 2011. The Primus Defendants (including the Company) amended their Statement of Defence and motion for summary judgment on October 6, 2015 to include a statute of limitations defense based on this change in theory. The Primus Defendants (including the Company) also filed procedural motions relating to the amendment. Xplornet disputes that the amendment changed its theory and opposes summary judgment. The hearing on summary judgment is now re-scheduled from October 7, 2015 to March 31, 2016. 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.

SHARE-BASED COMPENSATION

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

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 September 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 1,406,681 and 1,645,685 options granted during the nine months ended September 30, 2015 and 2014, respectively. Of the total options granted during the nine months ended September 30, 2015 and 2014, 885,173 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 nine months ended September 30, 2015 and 2014 was $1.55 and $1.40, 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:



	Nine Months Ended September 30,
	2015		2014
Expected option life	5.38 years		6.00 years
Risk-free interest rate	1.49% - 1.68%		1.96% - 2.73%
Expected volatility	36.29% - 40.50%		36.74% - 37.80%
Dividend yield	—	%	—	%

Total share-based compensation expense recognized by the Company during the three months ended September 30, 2015 and 2014 was $2.3 million and $0.7 million, respectively. Total share-based compensation expense recognized by the Company during the nine months ended September 30, 2015 and 2014 was $6.9 million and $1.7 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 nine months ended September 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	(1,008,253	)	$	8.40
Forfeitures	—		$	—
Unvested - September 30, 2015	869,563		$	8.10

As of September 30, 2015, the unvested restricted stock represented $3.7 million of compensation expense that is expected to be recognized over the weighted average remaining vesting period of 0.9 years. The number of shares of unvested restricted stock expected to vest is 869,563.

Stock Options

A summary of the Company’s stock option activity during the nine months ended September 30, 2015 is as follows:



	Shares		Weighted Average Exercise Price
Outstanding - December 31, 2014	3,573,141		$	4.27
Granted	1,406,681		$	6.49
Exercised	—		$	—
Forfeitures	(764,529	)	$	4.05
Outstanding - September 30, 2015	4,215,293		$	5.05
Eligible for exercise	2,117,941		$	5.02

Total options granted during the nine months ended September 30, 2015 include 715,476 options resulting from an option modification whereby 760,194 options were forfeited in the exchange. The modification related to the adjustment to the exercise price and number of options that are calculated on the Series A Preferred Stock. The Company has evaluated the impact of modification accounting under ASC 718 and concluded that the modification of terms of such instruments did not result in an increase in fair value before and after the modification date.

The following table summarizes the intrinsic values and remaining contractual terms of the Company’s stock options:



	Intrinsic Value (in thousands)		Weighted Average Remaining Life in Years
Options Outstanding - September 30, 2015	$	9,021	8.91
Options exercisable - September 30, 2015	$	4,466	8.78

As of September 30, 2015, the Company had 2,097,352 unvested stock options outstanding of which $1.8 million of compensation expense is expected to be recognized over the weighted average remaining vesting period of 0.74 years. The number of unvested stock options expected to vest is 2,097,352 shares, with a weighted average remaining life of 8.91 years, a weighted average exercise price of $5.05, and an intrinsic value of $4.6 million.

Equity [Abstract]

EQUITY

As of September 30, 2015 and December 31, 2014, there were 25,592,356 and 23,813,085 shares of common stock outstanding, respectively. As of September 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.

Certain 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 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 aggregate principal amount of the Additional 11% Notes issued to the holders of the Series A Preferred Stock in August 2015. The Company recorded this payment to other income (expense), net.

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 nine months ended September 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		September 30, 2015
Holders of Record Date	March 31, 2015		June 30, 2015		September 30, 2015

FAIR VALUE OF FINANCIAL INSTRUMENTS

9 Months Ended

Fair Value Disclosures [Abstract]

FAIR VALUE OF FINANCIAL INSTRUMENTS

Fair Value Measurement

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 nine months ended September 30, 2015.

Assets by Hierarchy Level

Assets measured and carried at fair value in the financial statements are summarized below (in thousands).

The methods and assumptions the Company uses to estimate the fair value of assets and liabilities measured at fair value on a recurring basis are summarized below.

Common Equity - consists of common stock of publicly traded companies. The fair values of publicly traded equity securities are based on quoted market prices in active markets.

Convertible Debt (the Debenture) - the Debenture was valued at its as-converted value based on the number of as-converted shares as implied by the prevalent conversion price and Gaming Nation's common stock price as of the valuation date.

Warrants (DTV) - the Company utilized a Black-Scholes model. Warrants were treated as European Options due to the absence of dividends, which creates a lack of incentive to exercise the warrants until the expiry date as an investor would prefer to earn interest on the cash to be used for exercising the warrants. The Company performed a sensitivity analysis around the implied value of the company's common stock when convertible debt was converted into common stock at $2.25 per share on June 30, 2015. The Company also calibrated the stock price based on changes in the market capitalization and enterprise value/EBITDA and revenue multiples for identified comparable companies through the valuation date.

Cash Equivalents - consists of money market instruments which are generally valued using unadjusted quoted prices in active markets that are accessible for identical assets.

Level 3 Measurements and Transfers

Fair Value of Financial Instruments

The Company is required by general accounting principles for Fair Value Measurements and Disclosures to disclose the fair value of certain financial instruments including those that are not carried at fair value. The following table presents the carrying amounts and estimated fair values of the Company’s financial instruments, which were not measured at fair value on a recurring basis, at September 30, 2015 and December 31, 2014. This table excludes carrying amounts reported in the condensed consolidated balance sheets for cash, 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.

Common Equity (DTV) – The Company performed a sensitivity analysis around the implied value of the company's common stock when convertible debt was converted into common stock at $2.25 per share on June 30, 2015. The Company also calibrated the stock price based on changes in the market capitalization and enterprise value/EBITDA and revenue multiples for identified comparable companies through the valuation date.

Warrants - the Company utilized a Black-Scholes model to determine the estimated fair value of warrants convertible into Novatel's common stock and Monte Carlo simulation to determine the estimated fair value of the warrants convertible into Gaming Nation's common stock.

Long-term Debt - The fair value of the Company’s long-term debt was determined using Bloomberg Valuation Service BVAL. The methodology combines direct market observations from contributed sources with quantitative pricing models to generate evaluated prices.

BACKLOG	9 Months Ended
BACKLOG	Sep. 30, 2015
Risks and Uncertainties [Abstract]
BACKLOG	BACKLOG Schuff’s backlog was $381.6 million ($245.9 million under contracts or purchase orders and $135.7 million under letters of intent) at September 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 $122.5 million, representing 32.1% of Schuff’s backlog at September 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

Discontinued Operations and Disposal Groups [Abstract]

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):

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 nine months ended September 30, 2015 and 2014 due to the results of operations being a loss from continuing operations, net of tax. For the three and nine months ended September 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 nine months ended September 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):

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS On October 16, 2015, the Company announced a proposed offering of our common stock in a registered public offering. The offering was made by means of a prospectus supplement to a previously filed Registration Statement on Form S-3, which was declared effective by the U.S. Securities and Exchange Commission on October 27, 2015. On November 4, 2015, the Company issued 7,350,000 shares of its common stock in an underwritten public offering (which included 1,800,000 shares pursuant to an option to purchase shares of the Company's common stock granted by the underwriters). In addition the Company granted an over-allotment option to purchase an additional 1,102,500 shares of common stock at the public offering price of $7.00 per share, less underwriting discounts. The gross proceeds from this equity offering were approximately $51.5 million before deducting underwriting discounts, commissions, and estimated offering expenses. The Company intends to use the funds to finance investments in existing subsidiaries and operations, and potential acquisitions, including all or a portion of the consideration for the insurance companies acquisitions, development and redevelopment activities, debt repayments, the repurchase or redemption of preferred stock and for other general corporate purposes. On November 5, 2015 the Company announced that the underwriter of the previously announced underwritten public offering of 7,350,000 newly issued shares of the Company’s common stock has exercised its over-allotment option to purchase an additional 1,102,500 shares of common stock at the public offering price of $7.00 per share, less underwriting discounts. After giving effect to the over-allotment closing, the total number of shares sold by the Company in its offering increased to 8,452,500 shares, which resulted in aggregate gross proceeds of approximately $59.2 million, before deducting underwriting discounts, commissions, and estimated offering expenses. On November 5, 2015 the Company also announced that it expects to receive an $8.2 million dividend from its subsidiary, Schuff International, Inc., on December 1, 2015.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Sep. 30, 2015
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation - The accompanying unaudited condensed consolidated financial statements of the Company 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 and nine months ended September 30, 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.
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.
Reclassification	Reclassification - Certain previous year amounts have been reclassified to conform with current year presentations related to the reporting of new balance sheet line items.
Newly Adopted Accounting Principles and 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, Accounting Standards Update (“ASU”) 2014-8, “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 September 2015, the FASB issued ASU 2015-16, “Business Combination Topic No. 805: Simplifying the Accounting for Measurement - Period Adjustments”, which requires adjustments to provisional amounts that are identified during the measurement period to be recognized in the reporting period in which the adjustment amounts are determined. This includes any effect on earnings of changes in depreciation, amortization, or other income effects as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. 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 August 2015, the FASB issued ASU 2015-15, “Interest - Imputation of Interest Subtopic No. 835-30: Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements”, which codifies an SEC staff announcement that entities are permitted to defer and present debt issuance costs related to line-of-credit arrangements as assets. 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 August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers Topic No. 606: Deferral of the Effective Date”, which defers the effective date of the new revenue recognition standard by one year. Early adoption is permitted. The Company’s effective date for adoption is January 1, 2018. 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 July 2015, the FASB issued ASU 2015-11, “Inventory Topic No. 330: Simplifying the Measurement of Inventory”, which requires inventory within the scope of the ASU to be measured using the lower of cost and net realizable value. Inventory excluded from the scope of the ASU will continue to be measured at the lower of cost or market. Early adoption is permitted. The Company’s effective date for adoption is January 1, 2017. 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 May 2015, the FASB issued ASU 2015-8, “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 2015-3, “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 2015-2, “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 2015-1, “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.
