Debt

As of June 30, 2019 and December 31, 2018, the Company’s current debt consisted of the New Term Loan Facility and the Term Loan Facility (as defined below) with balances of $490,523 and $272,192, respectively.

New Term Loan Facility

On August 16, 2018, the Company entered into a Term Loan Facility (the “Term Loan Facility”). On December 31, 2018, the Company amended its previous Term Loan Facility to borrow up to an aggregate principal amount of $500,000 (the “New Term Loan Facility”) from a syndicate of two lenders. The Company initially borrowed $280,000 under the New Term Loan Facility. On March 21, 2019, the Company drew an additional $220,000 under the New Term Loan Facility, bringing the Company’s total outstanding borrowings to $500,000 under the New Term Loan Facility.

All borrowings under the New Term Loan Facility bear interest at a rate selected by the Company of either (i) the LIBOR divided by one minus the applicable reserve requirement plus a spread of 4.0% or (ii) subject to a floor of 1.0%, a Base Rate equal to the higher of (a) the Prime Rate, (b) the Federal Funds Rate plus 1⁄2 of 1.0% or (c) the 1-month LIBOR rate plus 1.0% plus a spread of 3.0%. The New Term Loan Facility is set to mature on December 31, 2019 and is repayable in quarterly installments of $1,250, with a balloon payment due at maturity. The Company has the option to extend the maturity date for two additional six-month periods; upon the exercise of each extension option, the spread on LIBOR and Base Rate increases by 0.5%. To exercise the extension option, the Company must pay a fee equal to 1.0% of the outstanding principal balance at the time of the exercise of the option.

The New Term Loan Facility is secured by mortgages on certain properties owned by the Company’s subsidiaries, in addition to other collateral. The Company is required to comply with certain financial covenants and other restrictive covenants customary for facilities of this type, including restrictions on indebtedness, liens, acquisitions and investments, restricted payments and dispositions. The New Term Loan Facility also provides for customary events of default, prepayment and cure provisions.

The Company paid $4,400 of additional fees in connection with the $220,000 draw on the New Term Loan Facility. These fees were capitalized as a reduction to the New Term Loan Facility on the condensed consolidated balance sheets. The total unamortized deferred financing costs as of June 30, 2019 was $6,977.

Interest and related amortization of debt issuance costs recognized during major development and construction projects are capitalized and included in the cost of the project. Amortization of debt issuance costs were $3,166 and $165 for the three months ended June 30, 2019 and 2018, respectively, of which $1,558 and $0 were capitalized, respectively, and $5,230 and $339 for the six months ended June 30, 2019 and 2018, respectively, of which $2,641 and $0 were capitalized, respectively.

Income taxes

16.	Income taxes

In connection with the IPO, NFE contributed the net proceeds from the IPO to NFI in exchange for NFI LLC Units, and NFE became the managing member of NFI. NFI is a limited liability company that is treated as a partnership for U.S. federal income tax purposes and for most applicable state and local income tax purposes. As a partnership, NFI is not subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by NFI is passed through to and included in the taxable income or loss of its members, including NFE, on a pro rata basis, subject to applicable tax regulations. NFE is subject to U.S. federal income taxes, in addition to state and local income taxes, with respect to its allocable share of any taxable income or loss of NFI. Additionally, NFI and its subsidiaries are subject to income taxes in the various foreign jurisdictions in which they operate.

In connection with the IPO, NFE recorded a deferred tax asset related to the differential between its outside basis in its investment in NFI and NFE’s share of the basis of the assets of NFI, which was $44,473 at February 4, 2019.

The Company records a valuation allowance against its deferred tax assets to reduce the net carrying value to an amount that it believes is more likely than not to be realized. As of June 30, 2019, the Company concluded, based on the weight of all available positive and negative evidence, those deferred tax assets recorded as part of the IPO are not more likely than not to be realized and accordingly, a full valuation allowance has been recorded on this deferred tax asset as of June 30, 2019.

Jamaica

NFI’s subsidiaries incorporated in Jamaica are subject to income tax which is computed at 25% of the relevant subsidiaries’ results for the year, adjusted for tax purposes.

Bermuda

NFI has subsidiaries incorporated in Bermuda. Under current Bermuda law, the Company is not required to pay taxes in Bermuda on either income or capital gains. The Company has received an undertaking from the Bermuda government that, in the event of income or capital gain taxes being imposed, it will be exempted from such taxes until 2035.

Ireland

NFI acquired Shannon LNG on November 9, 2018. The Shannon LNG entities are incorporated in Ireland and had net operating loss carryforwards of approximately $41,395 as of the acquisition date. These losses were evaluated to determine if any would be subject to a limitation resulting from the acquisition. The Company concluded, based on the weight of all available positive and negative evidence, those deferred tax assets relating to the net operating loss carryforwards are not more likely than not to be realized and accordingly, a full valuation allowance has been recorded on these deferred tax assets as of June 30, 2019.

Puerto Rico

NFI has a subsidiary, NFEnergia LLC (NFEnergia) incorporated in Puerto Rico. NFEnergia is treated as a controlled foreign coporation for U.S. federal income tax purposes. The entity has not yet begun operations in Puerto Rico and has been in a loss position since it was organized in 2017. A full valuation allowance has been recorded against deferred tax assets related to those losses as of June 30, 2019.

Total Operations

The effective tax rate for the three months ended June 30, 2019 and June 30, 2018 was (0.30)% and (1.51)%, respectively. The total tax expense for the three months ended June 30, 2019 and 2018 was $155 and $280, respectively.

The effective tax rate for the six months ended June 30, 2019 and June 30, 2018 was (0.36)% and (0.31)%, respectively. The total tax expense for the six months ended June 30, 2019 and 2018 was $401 and $93, respectively.

Contingencies

As of December 31, 2016, the Company had accrued for $1,204 of tangible personal property tax levied in the State of Florida with respect to the Company’s LNG plant in Hialeah, Florida. During 2017, the Company paid this amount in full and subsequently initiated legal proceedings to challenge the tax amount for a full or partial rebate. The Company successfully challenged the tax amount, including penalties, and received a full rebate. The State of Florida has appealed the determination and the Company repaid the rebate amount in order to avoid penalties and charges while the appeal is under consideration.

As of the date at which these condensed consolidated financial statements were issued, the appeal has not been concluded. Should the State of Florida lose the appeal, the Company expects a full refund which will be recognized as a gain contingency recognized in earnings when the cash is received.

Upon the reorganization, New Fortress Energy Holdings obtained the same number of Class B shares in NFE. Class B shares do not share in the earnings or losses of the Company and are therefore not participating securities. As such, separate presentation of basic and diluted net loss per share for Class B shares under the two-class method has not been presented.

During the six months ended June 30, 2019, the Company granted RSUs to select officers, employees, non-employee members of the board of directors, and select non-employees under the Incentive Plan.

The Company estimates the fair value of RSUs on the grant date based on the closing price of the underlying shares on the grant date and other fair value adjustments to account for a post-vesting holding period. These fair value adjustments were estimated based on the Finnerty model.

For the six months ended June 30, 2019, cumulative compensation expense recognized for forfeited awards of $56 was reversed.

The following table summarizes the RSU activity for the six months ended June 30, 2019:

Non-vested RSUs as of June 30, 2019		3,959,725		$	13.46

During the six months ended June 30, 2019, the Company recognized a compensation expense of $28,008, of which $27,679 and $329 are recorded in Selling, general and administrative and Operations and maintenance, respectively. During the three months ended June 30, 2019, the Company recognized a compensation expense of $8,971, of which $8,711 and $260 are recorded in Selling, general and administrative and Operations and maintenance, respectively. The Company recognizes the income tax benefits resulting from vesting of RSUs in the period they vest, to the extent the compensation expense has been recognized.

As of June 30, 2019, the Company had 3,959,725 non-vested RSUs subject to service conditions and therefore had unrecognized compensation costs of approximately $42,629. The non-vested RSUs will vest over a period from ten months to three years following the grant date. The weighted-average remaining vesting period of non-vested RSUs totaled 1.53 years as of June 30, 2019.

The Senior Secured Bonds will be secured by the dual-fired combined heat and power facility in Clarendon, Jamaica (the “CHP Plant”) that is currently under construction and related receivables and assets, and the proceeds will be used to fund the completion of the CHP Plant and to reimburse advances made by the Company. Upon completion of certain conditions, South Power will have the ability to issue an additional $63,000 Senior Secured Bonds.

The Senior Secured Bonds bear interest at an annual fixed rate of 8.25% and will mature 15 years from the closing date of each tranche. No principal payments will be due for the first seven years. After seven years, quarterly principal payments of approximately 1.6% of the original principal amount will be due, with a 50% balloon payment due upon maturity. Interest payments on outstanding principal balances will be due quarterly.

The Senior Unsecured Bonds will bear interest at an annual fixed rate of 11.00% and will mature 17 years from the closing date. No principal payments will be due for the first nine years. After nine years, principal payments will be due quarterly on an escalating schedule. Interest payments on outstanding principal balances will be due quarterly.

South Power will be required to comply with certain financial covenants as well as customary affirmative and negative covenants, including limitations on incurring additional indebtedness.
