Puna

On May 3, 2018, the Kilauea volcano located in close proximity to our Puna 38 MW geothermal power plant in the Puna district of Hawaii's Big Island erupted following a significant increase in seismic activity in the area. Before it stopped flowing, the lava covered the wellheads of three geothermal wells, monitoring wells and the substation of the Puna complex and an adjacent warehouse that stored a drilling rig that was also consumed by the lava. The insurance policy coverage for property and business interruption is provided by a consortium of insurers. All the insurers accepted and started paying for the costs to rebuild the destroyed substation, and during the first quarter of 2019, the Company received an additional $1.5 million of such proceeds. However, only some of the insurers accepted that the business interruption coverage started in May 2018 and during the first and second quarters of 2019, the Company received and recorded an additional $8.1 million of such proceeds which were included under cost of revenues in the condensed consolidated statements of operations and comprehensive income for the six months ended June 30, 2019. The Company is still in discussions to reach an understanding with all insurers to start paying for the business interruption as of May 2018. The Company is still assessing the damages in the Puna facilities and continues to coordinate with Hawaii Electric Light Company (“HELCO”) and local authorities to bring the power plant back to operation.

As of August 2019, the Company continues to make good progress in the efforts to resume the operation at the Puna power plant. The Company expects that the plant refurbishment activities will be completed on schedule by the end of 2019 and that the plant will resume operations as soon as the local permitting and transmission network upgrades being undertaken by our local utility partner are completed in early 2020. In the well field area, during work to remove the plugs from the geothermal wells the Company found that two of the production wells were damaged and it will have to repair them or drill a new well. In addition, some of the other production wells at the Puna power plant need to be cleaned out. Once Puna resumes operation, the Company will gradually increase the power plant generating capacity as it completes the necessary repairs and drilling.

The Company continues to assess the accounting implications of this event on the assets and liabilities on its balance sheet and whether an impairment will be required. Any significant damage to the geothermal resource or continued shut-down following the lava event at the Puna facilities could have an adverse impact on the power plant's electricity generation and availability, which in turn could have a material adverse impact on our business and results of operations. 

DEG 3 Loan

On January 4, 2019, an indirect subsidiary of the Company (“OrPower 4”) entered into an additional $41.5 million subordinated loan agreement with Deutsche Investitions-und Entwicklungsgesellschaft mbH ("DEG") (the “DEG 3 Loan Agreement”) and on February 28, 2019, OrPower 4 completed a drawdown of the full loan amount, with a fixed interest rate of 6.04% for the duration of the loan (the “DEG 3 Loan”). The DEG 3 Loan will be repaid in 19 equal semi-annual principal installments commencing June 21, 2019, with a final maturity date of  June 21, 2028. Proceeds of the DEG 3 Loan were used by OrPower 4 to refinance upgrades to Plant 1 of the Olkaria III Complex, which were originally financed using equity. The DEG 3 Loan is subordinated to the senior loan provided by Overseas Private Investment Corporation (“OPIC”) for Plants 1-3 of the Olkaria III Complex. The DEG 3 Loan is guaranteed by the Company.

Migdal Senior Unsecured Loan

On March 25, 2019, the Company entered into a first addendum (“First Addendum”) to the loan agreement (the "Migdal Loan Agreement") with Migdal Insurance Company Ltd., Migdal Makefet Pension and Provident Funds Ltd. and Yozma Pension Fund of Self-Employed Ltd., all entities within the Migdal Group, a leading insurance company and institutional investor in Israel dated March 22, 2018. The First Addendum provides for an additional loan by the lenders to the Company in an aggregate principal amount of $50.0 million (the “Additional Migdal Loan”). The Additional Migdal Loan will be repaid in 15 semi-annual payments of $2.1 million each, commencing on September 15, 2021, with a final payment of $18.5 million on March 15, 2029. The Additional Migdal Loan bears interest at a fixed rate of 4.6% per annum, payable semi-annually, subject to adjustment in certain circumstances as described below.

The Additional Migdal Loan was entered into under substantially the same terms and conditions of the Migdal Loan Agreement as disclosed in the Company’s Form 10-K for the year ended December 31, 2018.

Write-offs of unsuccessful exploration activities

There were no write-offs of unsuccessful exploration activities for the three and six months ended June 30, 2019. Write-offs of unsuccessful exploration activities for the three and six months ended June 30, 2018 were $0 and $0.1 million, respectively.

Concentration of credit risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of temporary cash investments and accounts receivable.

The Company places its temporary cash investments with high credit quality financial institutions located in the United States (“U.S.”) and in foreign countries. At June 30, 2019 and December 31, 2018, the Company had deposits totaling $44.1 million and $31.3 million, respectively, in ten U.S. financial institutions that were federally insured up to $250,000 per account. At June 30, 2019 and December 31, 2018, the Company’s deposits in foreign countries amounted to approximately $79.4 million and $93.9 million, respectively.

At June 30, 2019 and December 31, 2018, accounts receivable related to operations in foreign countries amounted to approximately $107.4 million and $102.0 million, respectively. At June 30, 2019 and December 31, 2018, accounts receivable from the Company’s primary customers amounted to approximately 56% and 56% of the Company’s accounts receivable, respectively.

Sierra Pacific Power Company and Nevada Power Company (subsidiaries of NV Energy, Inc.) accounted for 16.5% and 17.0% of the Company’s total revenues for the three months ended June 30, 2019 and 2018, respectively, and 17.3% and 16.7% of the Company’s total revenues for the six months ended June 30, 2019 and 2018, respectively.

Southern California Public Power Authority (“SCPPA”) accounted for 17.2% and 14.9% of the Company’s total revenues for the three months ended June 30, 2019 and 2018, respectively, and 18.3% and 15.6% of the Company’s total revenues for the six months ended June 30, 2019 and 2018, respectively.

Kenya Power and Lighting Co. Ltd. accounted for 16.6% and 16.6% of the Company’s total revenues for the three months ended June 30, 2019 and 2018, respectively, and 16.0% and 15.8% of the Company’s total revenues for the six months ended June 30, 2019 and 2018, respectively.

The Company has historically been able to collect on substantially all of its receivable balances. As of June 30, 2019, the amount overdue from KPLC in Kenya was $34.5 million of which $10.5 million was paid in July 2019 and $5.9 million in August 2019. These amounts represent an average of 54 days overdue. In Honduras, we continue to see deterioration in the collection from Empresa Nacional de Energía Eléctrica (“ENEE”) and as of June 30, 2019, the amount overdue is $20.1 million of which $3.1 million was paid in August 2019. These amounts represent an average of 108 days, an increase of 18 days from March 31, 2019. Due to obligations of the Honduran government to support the Company, the Company believes it will be able to collect all past due amounts, and therefore no provision for doubtful accounts has been recorded.

Additionally, Pacific Gas and Electric Corporation (“PG&E Corporation”) and its subsidiary Pacific Gas and Electric Company (“PG&E”), which accounts for 1.0% and 1.2% of our total revenues for the three and six months ended June 30, 2019, are facing extraordinary challenges relating to a series of catastrophic wildfires that occurred in Northern California in 2017 and 2018. As a result, on January 29, 2019, PG&E Corporation and its subsidiary, PG&E, voluntarily filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code. The Company is closely monitoring its PG&E balance to ensure cash receipts are received timely each month.

NOTE 2 — NEW ACCOUNTING PRONOUNCEMENTS

New accounting pronouncements effective in the six-month period ended June 30, 2019

Leases

 In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This new standard introduced a number of changes and simplified previous guidance, primarily the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases. The new standard retained the distinction between finance leases and operating leases and the classification criteria between the two types remains substantially similar. Also, lessor accounting remained largely unchanged from previous guidance. However, key aspects of the new standard were aligned with the revenue recognition guidance in Topic 606. Additionally, the new standard defined a lease as a contract, or part of a contract, that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Control over the use of the identified asset means that the customer has both (a) the right to obtain substantially all of the economic benefits from the use of the asset and (b) the right to direct the use of the asset. The Company adopted this new standard as of January 1, 2019 using the modified retrospective approach and accordingly recognized a cumulative-effect adjustment to the opening balance of retained earnings, which was an immaterial amount, with no restatement of comparative information.

In accordance with the new standard, for agreements in which the Company is the lessee, the Company applies a unified accounting model by which it recognizes a right-of-use asset ("ROU") and a lease liability at the commencement date of the lease contract for all the leases in which the Company has a right to control identified assets for a specified period of time. The classification of the lease as a finance lease or an operating lease determines the subsequent accounting for the lease arrangement.

Upon the adoption of the new standard the Company, both as a lessee and as a lessor, chose to apply the following permitted practical expedients:

1. Not reassess whether any existing contracts are or contain a lease;

2. Not reassess the classification of leases that commenced before the effective date (for example, all existing leases that were classified as operating leases in accordance with Topic 840 will continue to be classified as operating leases, and all existing leases that were classified as capital leases in accordance with Topic 840 will continue to be classified as finance leases);

3. Exclude initial direct costs from measurement of the ROU asset at the date of initial application;

4. Applying the practical expedient (for a lessor) to not separate non-lease components accounted for under Topic 606 from lease components and, instead, to account for each separate lease component and the non-lease components associated with that lease component as a single component. If the non-lease components are the predominant components, the Company will account for the combined component as a single performance obligation entirely in accordance with Topic 606. Otherwise, the combined component will be accounted as an operating lease entirely in accordance with the new standard.

5. Applying the practical expedient (for a lessee) regarding the recognition and measurement of short-term leases, for leases for a period of up to 12 months from the commencement date. Instead, the company will continue to recognize the lease payments for those leases in profit or loss on a straight-line basis over the lease term.

Since the Company elected to apply the practical expedients above, it applied the new standard to all contracts entered into before January 1, 2019 and identified as leases in accordance with Topic 840.

The new significant accounting policies regarding leases that were applied as from January 1, 2019 following the application of the new standard are as follows:

1.     Determining whether an arrangement contains a lease

On the inception date of the lease, the Company determines whether the arrangement is a lease or contains a lease, while examining if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

2.     The Company as a lessee

a.  Lease classification:

At the commencement date, a lease is a finance lease if it meets any one of the criteria below; otherwise the lease is an operating lease:

● The lease transfers ownership of the underlying asset to the lessee by the end of the lease term.

● The lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise.

● The lease term is for the major part of the remaining economic life of the underlying asset.

● The present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already reflected in the lease payments equals or exceeds substantially all of the fair value of the underlying asset.

● The underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of lease term.

b. Leased assets and lease liabilities - initial recognition

Upon initial recognition, the Company recognizes a liability at the present value of the lease payments to be made over the lease term, and concurrently recognizes a ROU asset at the same amount of the liability, adjusted for any prepaid or accrued lease payments, plus initial direct costs incurred in respect of the lease.

Since the interest rate implicit in the lease is not readily determinable, the incremental borrowing rate of the Company is used. The subsequent measurement depends of whether the lease is classified as a finance lease or an operating lease.

c.     The lease term

The lease term is the non-cancellable period of the lease plus periods covered by an extension or termination option if it is reasonably certain that the Company will exercise the option.

d.     Subsequent measurement of operating leases

After lease commencement, the Company measures the lease liability at the present value of the remaining lease payments using the discount rate determined at lease commencement (as long as the discount rate hasn’t been updated as a result of a reassessment event).

The Company subsequently measures the ROU asset at the present value of the remaining lease payments, adjusted for the remaining balance of any lease incentives received, any cumulative prepaid or accrued rent if the lease payments are uneven throughout the lease term and any unamortized initial direct costs.

Further, the Company will recognize lease expense on a straight-line basis over the lease term.

12

ORMAT TECHNOLOGIES, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

(Unaudited)

e.     Subsequent measurement of finance leases

After lease commencement, the Company measures the lease liability by increasing the carrying amount to reflect interest on the lease liability and reducing the carrying amount to reflect the lease payments made during the period. The Company shall determine the interest on the lease liability in each period during the lease term as the amount that produces a constant periodic discount rate on the remaining balance of the liability, taking into consideration the reassessment requirements.

After lease commencement, the Company measures the ROU assets at cost less any accumulated amortization and any accumulated impairment losses, taking into consideration the reassessment requirements. The Company amortizes the ROU asset on a straight-line basis, unless another systematic basis better represents the pattern in which the Company expects to consume the ROU asset’s future economic benefits. The ROU asset is amortized over the shorter of the lease term or the useful life of the ROU asset as follows:

	(in years)
Land		1	-	35
Automobiles			5
Building			15

The total periodic expense (the sum of interest and amortization expense) of a finance lease is typically higher in the early periods and lower in the later periods.

f.      Variable lease payments:

Variable lease payments that depend on an index or a rate

On the commencement date, the lease payments shall include variable lease payments that depend on an index or a rate (such as the Consumer Price Index or a market interest rate), initially measured using the index or rate at the commencement date. The Company does not remeasure the lease liability for changes in future lease payments arising from changes in an index or rate unless the lease liability is remeasured for another reason. Therefore, after initial recognition, such variable lease payments are recognized in profit or loss as they are incurred.

Other variable lease payments:

Variable payments that depends on performance or use of the underlying asset are not included in the lease payments. Such variable payments are recognized in profit or loss in the period in which the event or condition that triggers the payment occurs.

3.     The Company as a lessor

At lease commencement, the Company as a lessor classifies leases as either finance or operating leases. Finance leases are further classified as a sales-type lease or as a direct financing lease. Under an operating lease, the Company recognizes the lease payment as income over the lease term, generally on a straight-line basis or as earned.

4. Impact of the new standard

a) Effects of the initial application of the new standard on the Company's consolidated balance sheets statement as of January 1, 2019:

	According to the previous accounting policy		The change			As presented according to Topic 842
	(Dollars in thousands)
As of January 1, 2019:
Prepaid expenses and other	$	51,441	$	(35,385	)	$	16,056

Property, plant and equipment, net		1,959,578		(12,855	)		1,946,723
Operating leases right of use		-		62,244			62,244
Finance leases right of use		-		13,476			13,476
Accounts payable and accrued expenses		116,362		(2,860	)		113,502
Current maturity of operating lease liabilities		-		7,532			7,532
Current maturity of finance lease liabilities		-		2,841			2,841
Other long-term liabilities		16,087		(9,970	)		6,117
Long term portion of operation lease liabilities		-		17,668			17,668
Long term portion of finance lease liabilities		-		10,668			10,668
Retained earnings		422,222		(58	)		422,164

The Operating leases right of use is higher than the related lease liabilities as a result of prepayments of leases, including the Puna lease and deferred financing lease costs.

b) A weighted-average nominal incremental interest rate of 5% and 7% was used to discount future lease payments in the calculation of the lease liabilities in respect of operating leases and in respect of finance leases, respectively.

Derivatives and Hedging

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. The amendments in this update better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. To meet that objective, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The adoption of this guidance did not have an impact on the Company’s consolidated financial statements.

Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income

In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220). The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). The guidance is effective for the fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The adoption of this guidance did not have an impact on the Company’s consolidated financial statements.

New accounting pronouncements effective in future periods

Financial Instruments—Credit Losses

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments—Credit Losses—Measurement of Credit Losses on Financial Instruments.” This guidance replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance will be effective beginning on January 1, 2020, including interim periods within that year. The Company is currently evaluating the potential effect on its consolidated financial statements.

NOTE 5— FAIR VALUE OF FINANCIAL INSTRUMENTS

The fair value measurement guidance clarifies that fair value is an exit price, representing the amount that would be received upon selling an asset or paid upon transferring a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under the fair value measurement guidance are described below:

Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities.

17

(Unaudited)

Level 2 — Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3 — Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

The following table sets forth certain fair value information at June 30, 2019 and December 31, 2018 for financial assets and liabilities measured at fair value by level within the fair value hierarchy, as well as cost or amortized cost. As required by the fair value measurement guidance, assets and liabilities are classified in their entirety based on the lowest level of inputs that is significant to the fair value measurement.

The fair value of the long-term debt is determined by a valuation model, which is based on a conventional discounted cash flow methodology and utilizes assumptions of current borrowing rates. The fair value of revolving lines of credit is determined using a comparison of market-based price sources that are reflective of similar credit ratings to those of the Company.

The carrying value of financial instruments such as revolving lines of credit and deposits approximates fair value.

NOTE 8 — EARNINGS PER SHARE

Basic earnings per share attributable to the Company’s stockholders is computed by dividing net income or loss attributable to the Company’s stockholders by the weighted average number of shares of common stock outstanding for the period. The Company does not have any equity instruments that are dilutive, except for employee stock-based awards.

The table below shows the reconciliation of the number of shares used in the computation of basic and diluted earnings per share (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018

Weighted average number of shares used in computation of diluted earnings per share		51,094		50,958		51,058		51,001

The number of stock-based awards that could potentially dilute future earnings per share and that were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive was 174,334 and 232,925 for the three months ended June 30, 2019 and 2018, respectively, and 228,775 and 223,708 for the six months ended June 30, 2019 and 2018, respectively.

NOTE 9 — BUSINESS SEGMENTS

The Company has three reporting segments: the Electricity segment, the Product segment and the Other segment. These segments are managed and reported separately as each offers different products and serves different markets. The Electricity segment is engaged in the sale of electricity from the Company’s power plants pursuant to PPAs. The Product segment is engaged in the manufacture, including design and development, of turbines and power units for the supply of electrical energy and in the associated construction of power plants utilizing the power units manufactured by the Company to supply energy from geothermal fields and other alternative energy sources. The Other segment is engaged in management of curtailable customer loads under contracts with U.S. retail energy providers and directly with large commercial and industrial customers as well as battery storage as a service ("BSAAS"). Under this segment, we provide energy storage, demand response and energy management related services through our Viridity Energy Solutions Inc. ("Viridity") business.

Transfer prices between the operating segments are determined based on current market values or cost-plus markup of the seller’s business segment.

NOTE 10 — COMMITMENTS AND CONTINGENCIES

● On May 21, 2018, a motion to certify a class action was filed in Tel Aviv District Court against Ormat Technologies, Inc. and 11 officers and directors.  The alleged class is defined as "All persons who purchased Ormat shares on the Tel Aviv Stock Exchange between August 3, 2017 and May 13, 2018". The motion alleges that the Company violated  Sections 31(a)(1) and 38C of the Israeli Securities Law because it allegedly: (1) misled investors by stating in its financial statements that it maintains effective internal controls over its accounting policies and procedures, however the Company's internal controls had material weaknesses which led to erroneous accounting in its 2017 unaudited quarterly reports that had to be restated, including adjustments to the Company’s net income and shareholders’ equity; and (2) failed to issue an immediate report in Israel until May 16, 2018, analogous to the report that was released in the United States on May 11, 2018 stating, inter alia, that the errors in its financial reports affected its balance sheet and would be remedied in its 2017 annual report. The Company filed an agreed motion to the Tel Aviv District Court to stay the proceedings in Israel until a final decision in the US case (Mac Costas) is adjudicated.

● On June 11, 2018, a putative class action was filed by Mac Costas on behalf of alleged shareholders that purchased or acquired the Company's ordinary shares between August 8, 2017 and May 15, 2018 was commenced in the United States District Court for the District of Nevada against the Company and its Chief Executive Officer and Chief Financial Officer.  The complaint asserts claim against all defendants pursuant to Section 10(b) of the Exchange Act, as amended, and Rule 10b-5 thereunder and against its officers pursuant to Section 20(a) of the Exchange Act.  The complaint alleges that the Company's Form 10-K for the years ended December 31, 2016 and 2017, and Form 10-Qs for each of the quarters in the nine months ended September 30, 2017 contained material misstatements or omissions, among other things, with respect to the Company’s tax provisions and the effectiveness of its internal control over financial reporting, and that, as a result of such alleged misstatements and omissions, the plaintiffs suffered damages. Following the Mac Costas filing and in accordance with the terms of the Private Securities Litigation Reform Act of 1995 (“PSLRA”), a number of law firms filed applications on behalf of entities purporting to hold shares in the Company, seeking to be appointed as lead plaintiff and lead counsel in the action. On March 12, 2019 the court appointed Phoenix Insurance Company Ltd. (“Phoenix Insurance”) as lead plaintiff and approved their selection of lead counsel. Pursuant to a scheduling stipulation entered between the parties, Phoenix Insurance timely filed its consolidated amended complaint, and the Company has timely filed its motion to dismiss. Under the scheduling stipulation, Phoenix Insurance must file their Opposition by August 26, 2019, and the Company must file their reply by September 25, 2019. The Company believes that it has valid defenses under law and intends to defend itself vigorously. 

● On September 11, 2018, the Klein derivative action (“Klein Action”) was filed against the Company, our board and our Chief Executive Officer and Chief Financial Officer in the United States District Court for the District of Nevada, and on October 22, 2018, the Matthew derivative action (“Matthew Action”) was filed against the company, certain named present and former board members (Barniv, Beck, Boehm, Clark, Falk, Freedland, Granot, Joyal, Nishigori, Sharir, Stern and Wong) in the US District Court, District of Nevada.  The Klein complaint asserts four derivative causes of action generally arising from Ormat's restatement of its financial statements: (i) the individual defendants allegedly breached their fiduciary duties by allowing the company to improperly report its financials; (ii) the individual defendants allegedly were unjustly enriched by being compensated while breaching their fiduciary duties; (iii) the individual defendants allegedly committed corporate waste in paying officers and directors and by incurring legal costs and potential liability; and (iv) the director defendants allegedly breached Section 14(a) of the Exchange Act in connection with the issuance of 2018 proxy. The Matthew complaint similarly alleges derivatively a breach of fiduciary duties, abuse of control, gross mismanagement, and corporate waste by the named directors. On January 24, 2019, the Nevada Court entered an order consolidating the Klein Action and Matthew Action, and staying all deadlines and hearings in the consolidated action pending entry of an order on the motion to dismiss in the Mac Costas putative class action. Within thirty days of entry of an order on the motion to dismiss in the Mac Costas putative class action, the parties are required to meet and confer and to submit a proposed schedule for further proceedings in the consolidated action.

● Following the announcement of the Company’s acquisition of U.S. Geothermal Inc. (“USG”), a number of putative shareholder class action complaints were initially filed on behalf of USG shareholders between March 8, 2018 and March 30, 2018 against USG and the individual members of the USG board of directors.  All of the purported class action suits filed in Federal Court in Idaho have been voluntarily dismissed.  The single remaining class action complaint is a purported class action filed in the Delaware Chancery Court, entitled Riche v. Pappas, et al., Case No. 2018-0177 (Del. Ch., Mar. 12, 2018). An amended complaint was filed on May 24, 2018 under seal, under a confidentiality agreement that was executed by plaintiff.   The amended Riche complaint alleges state law claims for breach of fiduciary duty against former US Geothermal directors and seeks post-closing damages. The Company believes that it has valid defenses under law and intends to defend itself vigorously.

● On August 5, 2016, George Douvris, Stephanie Douvris, Michael Hale, Cheryl Cacocci, Hillary E. Wilt and Christina Bryan, acting for themselves and on behalf of all other similarly situated residents of the lower Puna District, filed a complaint in the Third Circuit Court for the State of Hawaii seeking certification of a class action for preliminary and permanent injunctive relief, consequential and punitive damages, attorney’s fees and statutory interest against Puna Geothermal Venture (“PGV”) and other presently unknown defendants. HELCO and other parties were later joined as co-defendants. The Parties have reached an amicable settlement which, on April 4, 2019, was recorded by the Court, and the claim dismissed.

● On March 29, 2016, a former local sales representative in Chile, Aquavant, S.A., filed a claim on the basis of unjust enrichment against Ormat’s subsidiaries in the 27th Civil Court of Santiago, Chile. The claim requests that the court order Ormat to pay Aquavant $4.6 million in connection with its activities in Chile, including the EPC contract for the Cerro Pabellon project and various geothermal concessions, plus 3.75% of Ormat geothermal products sales in Chile over the next 10 years. Pursuant to various motions submitted by the defendants and the plaintiffs to various courts, including the Court of Appeals, the case was removed from the original court and then refiled before the 11th Civil Court of Santiago.   The Civil Court has heard oral testimonies and the “factual” stage of the proceedings are completed. The Company believes that it has valid defenses under law and intends to defend itself vigorously.

In addition, from time to time, the Company is named as a party to various other lawsuits, claims and other legal and regulatory proceedings that arise in the ordinary course of our business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contract, property damage, punitive damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to such lawsuits, claims and proceedings, the Company accrues reserves when a loss is probable, and the amount of such loss can be reasonably estimated. It is the opinion of the Company’s management that the outcome of these proceedings, individually and collectively, will not be material to the Company’s consolidated financial statements as a whole.

ORMAT TECHNOLOGIES, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

(Unaudited)

NOTE 11 — INCOME TAXES

The Company’s effective tax rate expense (benefit) for the three months ended June 30, 2019 and 2018 was (11.2%) and 92.8%, respectively, and 14.5% and 2.8% for the six months ended June 30, 2019 and 2018, respectively. The effective rate differs from the federal statutory rate of 21% for the six months ended June 30, 2019 due to: (i) the impact of the recently enacted global intangible low tax income (“GILTI”); (ii) the increase in the valuation allowance on the deferred tax assets related to the limitation on interest expense under the recently enacted IRC section 163(j); (iii) withholding taxes related to the rescindment of APB 23 permanent reinvestment assertion; offset by: (iv) increase in foreign tax credit availability and utilization related to converting foreign tax deductions to credits; (v) forecasted generation of production tax credits and (vi) mix of business in various countries with higher and lower statutory tax rates than the federal tax rate.

As a result of the Tax Act, the Company is also subject to certain statutory restrictions on its interest deductions under IRC section 163(j) which limits the interest deductions to business interest income plus 30% of adjusted taxable income. Disallowed interest expense does not expire but can only be utilized in future years when an adjusted taxable income provides excess limitation. The Company is projecting an $8.9 million interest expense carryforward attribute which has a full valuation allowance.

As of June 30, 2019, we have revised our assertion to no longer indefinitely reinvest foreign funds held by our foreign subsidiaries, with the exception of a certain balance held in Israel, and have accrued the incremental foreign withholding taxes. Accordingly, during the six months ended June 30, 2019, we included a foreign income tax expense of $6.6 million related to foreign withholding taxes and an increase to the valuation allowance related to PTC’s of $1.9 million. In addition, a state income tax expense of $ 0.9 million was recorded.

Tax Audit in Kenya

On July 30, 2019, the Company received a Letter of Preliminary Findings from the Kenya Revenue Authority (“KRA”) relating to tax years 2013-2017 that were previously audited by the KRA. The letter sets forth a demand for approximately $77 million before any possible interest and penalties. Based on a preliminary review of the KRA letter, the company and its advisors believe it has strong arguments against the preliminary findings raised in the KRA letter.

NOTE 12 — SUBSEQUENT EVENTS

Cash dividend

On August 7, 2019, the Board of Directors of the Company declared, approved and authorized payment of a quarterly dividend of $5.6 million ($0.11 per share) to all holders of the Company’s issued and outstanding shares of common stock on August 20, 2019, payable on August 27, 2019.

Ijen transaction

On July 2, 2019 the Company closed a set of agreements to acquire from a Medco Power subsidiary 49% in the Ijen geothermal project company, which is holding a PPA and a geothermal license to develop the Ijen project in East Java in Indonesia for a total consideration of approximately $2.7 million. Under the terms of the agreements, Ormat will acquire 49% of the shares of the Ijen geothermal project company and will commit to additional funding for the project exploration and development, subject to specific conditions.  A subsidiary of Medco Power will retain 51% ownership in the company. Ormat and Medco will develop the project jointly.

General

Overview

We are a leading vertically integrated company that is primarily engaged in the geothermal and recovered energy power businesses. We are also operating in the storage, demand response and energy management business.

29

We design, develop, build, sell, own, and operate clean, environmentally friendly geothermal, solar PV and recovered energy-based power plants. In the geothermal and recovered energy we usually using equipment that we design and manufacture. Our objective is to become a leading global provider of renewable energy and we have adopted a strategic plan to focus on several key initiatives to expand our business.

Our owned geothermal power plants include both power plants that we have built and power plants that we have acquired. We have built all of our recovered energy-based plants. We currently conduct our business activities in three business segments:

● Electricity Segment. In the Electricity segment we develop, build, own and operate geothermal, solar PV and recovered energy-based power plants in the U.S. and geothermal power plants in other countries around the world and sell the electricity they generate;

● Product Segment.In the Product segment we design, manufacture and sell equipment for geothermal and recovered energy-based electricity generation and remote power units and provide services relating to the engineering, procurement and construction of geothermal, and recovered energy-based power plants; and

● Other Segment. In the Other segment, we provide energy storage, demand response and energy management related services as well as services relating to the engineering, procurement, construction, operation and maintenance of energy storage units through our Viridity Energy Solutions Inc. ("Viridity") business.

Our operations are conducted in the U.S. and the rest of the world. Our current generating portfolio includes geothermal power plants in the U.S., Kenya, Guatemala, Honduras, Guadeloupe and Indonesia, as well as recovered energy generation and Solar PV power plants and storage activity in the U.S.

Recent Developments

The most significant developments in our company and business since January 1, 2019 are described below.

● As of August 2019, we continue to make good progress in the efforts to resume the operation at the Puna power plant in Hawaii that was shut down following the Kilauea volcano eruption last year. We expect that our plant refurbishment activities will be completed on schedule by the end of 2019 and that the plant will resume operations as soon as the local permitting and transmission network upgrades being undertaken by our local utility partner are completed in early 2020. In the well field area, during work to remove the plugs from the geothermal wells we found that two of the production wells were damaged and we will have to repair them or drill a new well. In addition, some of the other production wells at the Puna power plant need to be cleaned out. Once Puna resumes operation, we will gradually increase the power plant generating capacity as we completes the necessary repairs and drilling.

● In July 2019, we commenced commercial operation of our first-ever geothermal and solar hybrid project, a 7MW AC solar expansion of our Tungsten Mountain geothermal project in Churchill County, Nevada. The electricity generated from the Tungsten Solar power plant will be used to offset the equipment’s energy use at the Tungsten geothermal facility, thus increasing the renewable energy delivered by the project under the Southern California Public Power Authority (SCPPA) portfolio contract. SCPPA and Los Angeles Department of Water and Power (LADWP) had the vision to enable this development through their innovative portfolio contract, which sought to maximize the output of their renewable facilities and furthering the transition away from coal power while maintaining a reliable power supply for Los Angeles.

● In July 2019 we announced that we signed and closed a set of agreements to acquire 49% of the Ijen geothermal project company, which is holding a PPA and geothermal license to develop the Ijen project in East Java, Indonesia, from Medco Power subsidiary. Under the terms of the agreements, Ormat will acquire 49% of the shares of the Ijen geothermal project company and will commit to additional funding for the project exploration and development, subject to specific conditions.  A subsidiary of Medco Power will retain 51% ownership in the company. Ormat and Medco will develop the project jointly.

The Ijen project assets, whose final capacity will be determined after exploration, include a geothermal concession and 30-year PPA for up to 110 MW capacity. The project is ready for exploration and development with some slim holes already drilled.

● In May 2019, we completed the drawdown of $23.5 million under a non-recourse loan agreement with Siemens Financial Services for the financing of Plumsted and Stryker, two 20 MW battery energy storage projects located in New Jersey. The loan bears interest of three months U.S. Libor plus 3.5% margin and its final maturity date is December 31, 2025.

30

● In March 2019, we entered into a first addendum (“First Addendum”) to the Migdal Loan Agreement with several entities within the Migdal Group, a leading insurance company and institutional investor in Israel. The First Addendum provides us with an additional loan by the lenders in an aggregate principal amount of $50.0 million that will be repaid in 15 semi-annual payments of $2.1 million each, commencing on September 15, 2021, with a final payment of $18.5 million on March 15, 2029. The $50.0 million loan bears interest at a fixed rate of 4.6% per annum, payable semi-annually.

● In March 2019, we announced the signing of a PPA between one of our subsidiaries and SCPPA. Under the PPA, SCPPA will purchase 16MW of power generated by the expected 30MW Casa Diablo-IV (“CD4”) geothermal project located in Mammoth Lakes, California. SCPPA will resell the output to the City of Colton. The CD4 power plant will be the first geothermal power plant built within the California Independent System Operator (“CAISO”) balancing authority in the last 30 years. The 16MW of energy deliveries under the PPA will begin no later than the end of 2021 with an extension option. The PPA is for a term of 25 years and has a fixed price of $68 per MWh. We intend to sell the balance of 14MW to other offtakers or at the spot market.

● In January 2019, we entered into a $41.5 million subordinated loan agreement with Deutsche Investitions-und Entwicklungsgesellschaft mbH (“DEG”) and on February 28, 2019, we completed a drawdown of the full loan amount, with a fixed interest rate of 6.04% for the duration of the loan. The loan will be repaid in 19 equal semi-annual principal installments commencing June 21, 2019, with a final maturity date of June 21, 2028. Proceeds of the loan were used to refinance upgrades to Plant 1 of the Olkaria III Complex.

Trends and Uncertainties

Different trends, factors and uncertainties may impact our operations and financial condition, including many that we do not or cannot foresee. However, we believe that our results of operations and financial condition for the foreseeable future will be primarily affected by trends, factors and uncertainties discussed in our 2018 Annual Report under “Part II - Item 7 – Management Discussion and Analysis of Financial Condition and Results of Operation” in addition to the information set forth in this report. These trends, factors and uncertainties are from time to time also subject to market cycles:

● Pacific Gas and Electric Corporation (“PG&E Corporation”) and its subsidiary Pacific Gas and Electric Company (“PG&E”), which accounts for 1.7% of our total revenues for the six months ended June 30, 2019, are facing extraordinary challenges relating to a series of catastrophic wildfires that occurred in Northern California in 2017 and 2018. If PG&E Corporation and PG&E are found liable for the wildfires, its potential liabilities could exceed $30 billion. As a result, on January 29, 2019, PG&E Corporation and PG&E, voluntarily filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code. We are closely monitoring our PG&E invoices to ensure cash receipts are received timely each month.

Revenues

For the six months ended June 30, 2019, approximately 98.0% of our Electricity segment revenues were from PPAs with fixed energy rates, which are not affected by fluctuations in energy commodity prices. We have variable price PPAs in California and Hawaii, which provide for payments based on the local utilities’ avoided cost, which is the incremental cost that the power purchaser avoids by not having to generate such electrical energy itself or purchase it from others, as follows:

● the energy rates under the PPAs in California for each of Heber 2 power plant in the Heber Complex and the G2 power plant in the Mammoth Complex, a total of between 30 megawatts (“MW”) and 40 MW, change primarily based on fluctuations in natural gas prices; and

● the prices paid for the electricity pursuant to the 25 MW PPA for the Puna Complex in Hawaii change primarily as a result of variations in the price of oil as well as other commodities.

To comply with obligations under their respective PPAs, certain of our project subsidiaries are structured as special purpose, bankruptcy remote entities and their assets and liabilities are ring-fenced. Such assets are not generally available to pay our debt, other than debt at the respective project subsidiary level. However, these project subsidiaries are allowed to pay dividends and make distributions of cash flows generated by their assets to us, subject in some cases to restrictions in debt instruments, as described below.

Electricity segment revenues are also subject to seasonal variations and can be affected by higher-than-average ambient temperatures, as described below under “Seasonality”.

Revenues attributable to our Product segment are based on the sale of equipment, engineering procurement and construction (“EPC”) contracts and the provision of various services to our customers. Product segment revenues may vary from period to period because of the timing of our receipt of purchase orders and the progress of our equipment manufacturing and execution of the relevant project.

31

Revenues attributable to our Other segment are mainly derived from BSAAS systems, demand response and energy management services and may fluctuate period to period. Pricing of such services and products are dependent on market supply and demand trends, market volatility, the need and price for ancillary services and other factors that may change over time.

The following table sets forth a breakdown of our revenues for the periods indicated:

The contribution of our domestic and foreign operations within our Electricity segment and Product segment to combined pre-tax income differ in a number of ways.

In the six months ended June 30, 2019 and 2018, 48% and 56% of our revenues were derived from international operations, respectively, and our international operations were more profitable than our U.S. operations. A substantial portion of international revenues came from Kenya and Turkey and, to a lesser extent, from Guadeloupe, Guatemala and Honduras and other countries. Our operations in Kenya contributed disproportionately to gross profit and net income.

Electricity Segment. Our Electricity segment domestic revenues were approximately 62% of our total Electricity segment for both the six months ended June 30, 2019 and 2018, respectively. However, domestic operations in our Electricity segment have higher costs of revenues and expenses than the foreign operations in our Electricity segment. Our foreign power plants are located in lower-cost regions, like Kenya, Guatemala, Honduras and Guadeloupe, which favorably impact payroll and well-field maintenance expenses among other items. They are also newer than most of our domestic power plants and therefore tend to have lower maintenance costs and higher availability factors than our domestic power plants. Consequently, in 2019 the international operations of the segment accounted for 49% of our total gross profits, 65% of our net income and 47% of our EBITDA.

Product Segment. Our Product segment foreign revenues were approximately 77% and 99% of our total Product segment revenues for the six months ended June 30, 2019 and 2018, respectively. Our Product segment foreign activity also benefits from lower costs of revenues and expenses than Product segment domestic activity such as labor and transportation costs. Accordingly, our Product segment foreign activity contributes more than our Product segment domestic activity to our pre-tax income from operations.

Seasonality

Electricity generation from some of our geothermal power plants is subject to seasonal variations; in the winter, our power plants produce more energy primarily attributable to the lower ambient temperature, which has a favorable impact on the energy component of our Electricity segment revenues and the prices under many of our contracts are fixed throughout the year with no time-of-use impact. The prices paid for electricity under the PPAs for the Heber 2 power plant in the Heber Complex, the Mammoth Complex and the North Brawley power plant in California, the Raft River power plant in Idaho and the Neal Hot Springs power plant in Oregon, are higher in the months of June through September. The higher payments payable under these PPAs in the summer months partially offset the negative impact on our revenues from lower generation in the summer attributable to a higher ambient temperature. As a result, we expect the revenues in the winter months to be higher than the revenues in the summer months.

 Breakdown of Cost of Revenues

The principal cost of revenues attributable to our three segments are discussed in our 2018 Annual Report under “Part II - Item 7 – Management Discussion and Analysis of Financial Condition and Results of Operation”.

Comparison of the Three Months Ended June 30, 2019 and the Three Months Ended June 30, 2018 

Total Revenues

Total revenues for the three months ended June 30, 2019 were $184.1 million, compared to $178.3 million for the three months ended June 30, 2018, which represented an 3.2% increase from the prior year period. This increase was attributable to (i) a 5.6% increase in Electricity segment revenues as compared to the corresponding period in 2018, (ii) a 5.3% decrease in our Product segment revenues as compared to the corresponding period in 2018, and (iii) a 145.3% increase in Other segment revenues as compared to the corresponding period in 2018, all as discussed below.

Electricity Segment

Revenues attributable to our Electricity segment for the three months ended June 30, 2019 were $129.1 million, compared to $122.2 million for the three months ended June 30, 2018, representing a 5.6% increase from the prior year period. This increase was primarily attributable to (i) the commencement of commercial operation of the third phase of our McGinness Hills Complex in Nevada, effective December 2018, which generated total Complex revenues of $22.6 million for the three months ended June 30, 2019 compared to $15.6 million for the three months ended June 30, 2018; (ii) the consolidation of USG which was acquired on April 24, 2018, and contributed $7.3 million for the three months ended June 30, 2019 compared to $3.5 million for the three months ended June 30, 2018; and (iii) the commencement of commercial operation of our Plant 1 expansion project in the Olkaria III Complex in Kenya, effective June 2018. The increase was partially offset due to (i) the shutdown of our Puna power plant following the Kilauea volcanic eruption on May 3, 2018 which resulted in a reduction of $4.5 million in revenues compared to the same period last year and (ii) a decrease in generation at some of our other power plants that were taken offline to address maintenance issues.

Power generation in our power plants increased by 5.7% from 1,434,314 MWh in the three months ended June 30, 2018 to 1,516,060 MWh in the three months ended June 30, 2019 primarily because of an increase in generation due to the commencement of commercial operation of the third phase of our McGinness Hills Complex in Nevada, Plant 1 expansion in Kenya and the acquisition of USG. The increase was partially offset by (i) the shutdown of our Puna power plant following the Kilauea Volcanic Eruption and (ii) lower generation at some of our other power plants mainly due to maintenance issues in the ordinary course of business.

Product Segment

Revenues attributable to our Product segment for the three months ended June 30, 2019 were $52.0 million, compared to $54.9 million for the three months ended June 30, 2018, which represented a 5.3% decrease. The decrease in our Product segment revenues was mainly due to projects in Turkey, which were completed in 2018. The decrease was partially offset by the start of three new projects in Turkey, New Zealand and Chile, which provided $24.1 million in revenue recognized during the three months ended June 30, 2019 and other projects mainly in Turkey and the U.S., which were started in 2018.

Other Segment

Revenues attributable to our Other segment for the three months ended June 30, 2019 were $3.0 million compared to $1.2 million for the three months ended June 30, 2018.  The Other segment includes revenues from the provision of energy storage demand response and energy management services.

Total Cost of Revenues

Total cost of revenues for the three months ended June 30, 2019 was $118.9 million, compared to $120.8 million for the three months ended June 30, 2018, which represented a 1.6% decrease. This decrease was attributable to a decrease of $7.5 million, or 9.2%, in cost of revenues from our Electricity segment, partially offset by an increase of $3.7 million, or 10.0%, in cost of revenues from our Product segment and $1.8 million, or 88.7%, in cost of revenues from our Other segment generated by our Viridity business, all as discussed below. As a percentage of total revenues, our total cost of revenues for the three months ended June 30, 2019 decreased to 64.6% from 67.8% for the three months ended June 30, 2018. This decrease was attributable to a decrease in cost of revenues as a percentage of total revenues in both our Electricity and Other segments, partially offset by an increase in cost of revenues as a percentage of total revenues in our Product segment.

37

Electricity Segment

Total cost of revenues attributable to our Electricity segment for the three months ended June 30, 2019 was $73.8 million, compared to $81.2 million for the three months ended June 30, 2018. This decrease was primarily attributable to a decrease in cost of revenues at our Puna power plant that was shut down immediately following the Kilauea volcanic eruption on May 3, 2018, as the cost of revenues at our Puna power plant for the three months ended June 30, 2019 includes business interruption recovery of $6.9 million. The decrease was offset partially by an increase due to: (i) additional cost of revenues from the commencement of commercial operation of the third phase of our McGinness Hills Complex plant in Nevada, effective December 2018, (ii) commencement of commercial operation of our Plant 1 expansion project in the Olkaria III Complex in Kenya, effective June 2018 and (iii) the consolidation of USG which was acquired on April 24, 2018. As a percentage of total Electricity revenues, our total cost of revenues attributable to our Electricity segment for the three months ended June 30, 2019 was 57.2%, compared to 66.5% for the three months ended June 30, 2018. This decrease was primarily attributable to the increase in gross profit due to the commencement of commercial operation of the third phase of our McGinness Hills Complex, the gross profit from USG, and a business interruption insurance recovery of $6.9 million relating to the Puna power plant in Hawaii. The Company achieved an increase in gross profit despite recording cost of revenues with no associated revenues because of the shut-down of the power plant following the Kilauea volcanic eruption in May 3, 2018. The cost of revenues attributable to our international power plants was 24.9% of our Electricity segment cost of revenues.

Product Segment

Total cost of revenues attributable to our Product segment for the three months ended June 30, 2019 was $41.3 million, compared to $37.6 million for the three months ended June 30, 2018, which represented a 10.0% increase. This increase was primarily attributable to higher competition, different product scope and different margins in the various sales contracts we entered into mainly in Turkey, New Zealand and Chile for the Product segment during these periods. As a percentage of total Product segment revenues, our total cost of revenues attributable to our Product segment for the three months ended June 30, 2019 was 79.4%, compared to 68.4% for the three months ended June 30, 2018.

 Other Segment

Cost of revenues attributable to our Other segment for the three months ended June 30, 2019 were $3.8 million compared to $2.0 million for the three months ended June 30, 2018. The Other segment includes cost of revenues related to the provision of energy storage, demand response and energy management services.

General and Administrative Expenses

General and administrative expenses for the three months ended June 30, 2019 were $14.2 million compared to $15.9 million for the three months ended June 30, 2018. The decrease was primarily attributable to (i) costs in the three months ended June 30, 2018, associated with our identification of a material weakness related to taxes in the fourth quarter of 2017, (ii) additional work and establishment of new controls to mitigate the material weakness and (iii) the additional work related to the restatement of our second, third and fourth quarter financial statements and our full-year 2017 financial statements. General and administrative expenses for the three months ended June 30, 2019 constituted 7.7% of total revenues for such period, compared to 8.9% for the three months ended June 30, 2018.

38

Operating Income

Operating income for the three months ended June 30, 2019 was $46.9 million, compared to $36.6 million for the three months ended June 30, 2018, which represented a 28.0% increase. The increase in operating income was primarily attributable to the increase in our Electricity segment gross margin, offset by a decrease in our Product segment gross margin. Operating income attributable to our Electricity segment for the three months ended June 30, 2019 was $43.5 million, compared to $27.5 million for the three months ended June 30, 2018.

Interest Expense, Net

Interest expense, net for the three months ended June 30, 2019 was $21.5 million, compared to $15.8 million for the three months ended June 30, 2018. This increase was primarily due to: (i) $50.0 million of proceeds from a senior unsecured loan received March 25, 2019; (ii) $96.0 million debt as part of the acquisition of USG; (iii) $1.4 million increase in interest related to the sale of tax benefits; (iv) $114.7 million of proceeds from a limited recourse loan received on October 29, 2018 from OPIC for financing the Honduras power plant and (v) $41.5 million of proceeds from a full recourse loan received on January 4, 2019 from DEG for financing the Kenya power plant, partially offset due to lower interest expense as a result of principal payments of long term debt.

Derivatives and Foreign Currency Transaction Gains (Losses)

Derivatives and foreign currency transaction gains for the three months ended June 30, 2019 were $0.0 million, compared to losses of $0.5 million for the three months ended June 30, 2018.

Income Attributable to Sale of Tax Benefits

Income attributable to the sale of tax benefits for the three months ended June 30, 2019 was $4.6 million, compared to $3.6 million for the three months ended June 30, 2018. This income primarily represents the value of PTCs and taxable income or loss generated by certain of our power plants allocated to investors under tax equity transactions in the three months ended June 30, 2019 compared to the value of PTCs and taxable income allocated to the investors in the three months ended June 30, 2018.

     Other Non-Operating Income (Expense), Net

Other non-operating income for the three months ended June 30, 2019 was $1.0 million, compared to $7.4 million for the three months ended June 30, 2018. Other non-operating income for the three months ended June 30, 2019 mainly includes income of $1.0 million from the sale of PG&E receivables relating to January 2019 invoice which was not paid because it occurred before PG&E filed for reorganization under Chapter 11 bankruptcy. Other non-operating income for the three months ended June 30, 2018 mainly includes $7.2 million of income related to our Puna power plant rig insurance settlement, which was damaged by the Kilauea volcanic eruption.

Income Taxes

Income tax benefit for the three months ended June 30, 2019 was $3.5 million compared to income tax provision of $29.1 million for the three months ended June 30, 2018. Our effective tax rate for the three months ended June 30, 2019 and June 30, 2018, was (11.2)% and 92.8%, respectively. Our effective tax rate is primarily based upon the composition of our income in different countries and changes related to valuation allowances for certain countries. Our aggregate effective tax rate for the three months ended June 30, 2019 differs from the 21% U.S. federal statutory tax rate due to: (i) the impact of the recently enacted global intangible low tax income (“GILTI”); (ii) the increase in the valuation allowance on the deferred tax assets related to the limitation on interest expense under the recently enacted IRC section 163(j); (iii) withholding taxes related to the rescindment of APB 23 permanent reinvestment assertion; offset by: (iv) increase in foreign tax credit availability and utilization related to converting foreign tax deductions to credits ;(v) forecasted generation of production tax credits and (vi) mix of business in various countries with higher and lower statutory tax rates than the federal tax rate.

Equity in Earnings (losses) of Investees, Net

Equity in earnings of investees, net for the three months ended June 30, 2019 was $1.2 million, compared to $0.4 million for the three months ended June 30, 2018. Equity in earnings of investees, net is derived from our 12.75% share in the earnings or losses in the Sarulla Consortium (“Sarulla”). The increase was mainly attributable to utilization of carryforward losses, offset partially by a decrease in gross margin due to well-field issues in the NIL power plant which resulted in low generation. Sarulla is currently developing a remediation plan with a target to increase generation in the near-term back to previous levels. We are following the remediation plans in Sarulla as well as the accounting impact and its implication on our financial statements and our investment in Sarulla.

Net Income

Net income for the three months ended June 30, 2019 was $36.2 million, compared to $2.7 million for the three months ended June 30, 2018, which represents an increase of $33.5 million. This increase in net income was primarily attributable to a decrease in income tax provision of $32.1 million, and an increase of $10.2 million in operating income partially offset by a decrease of $6.3 million in other non-operating income, and $5.7 million in interest expense, net, as discussed above.

Net Income Attributable to the Company’s Stockholders

Net income attributable to the Company’s stockholders for the three months ended June 30, 2019 was $33.9 million, compared to net loss attributable to the Company’s Stockholders of $0.3 million for the three months ended June 30, 2018, which represents an increase of $34.3 million. This increase was attributable to the increase in net income of $33.5 million, and a decrease of $0.7 million in net income attributable to noncontrolling interest mainly due to the shutdown of the Puna power plant in Hawaii, all as discussed above.

Total cost of revenues for the six months ended June 30, 2019 was $243.8 million, compared to $231.5 million for the six months ended June 30, 2018, which represented a 5.3% increase. This increase was attributable to an increase of $12.1 million, or 17.0%, in cost of revenues from our Product segment and $3.6 million, or 65.2%, in cost of revenues from our Other segment generated by our Viridity business, offset partially by a decrease of $3.4 million, or 2.2%, in cost of revenues from our Electricity segment, all as discussed below. As a percentage of total revenues, our total cost of revenues for the six months ended June 30, 2019 decreased to 63.6% from 63.9% for the six months ended June 30, 2018. This slight decrease was attributable to a decrease in cost of revenues as a percentage of total revenues in both our Electricity and Other segments, partially offset by an increase in cost of revenues as a percentage of total revenues in our Product segment.

Electricity Segment

Total cost of revenues attributable to our Electricity segment for the six months ended June 30, 2019 was $151.3 million, compared to $154.7 million for the six months ended June 30, 2018. This decrease was primarily attributable to a decrease in cost of revenues at our Puna power plant that was shut down immediately following the Kilauea volcanic eruption on May 3, 2018. The cost of revenues at our Puna power plant for the six months ended June 30, 2019, include a business interruption recovery of $8.1 million. The decrease in cost of revenues was offset partially by an increase due to: (i) additional cost of revenues from the commencement of commercial operation of the third phase of our McGinness Hills Complex plant in Nevada, effective December 2018 and (ii) commencement of commercial operation of our Plant 1 expansion project in the Olkaria III Complex in Kenya, effective June 2018. As a percentage of total Electricity revenues, our total cost of revenues attributable to our Electricity segment for the six months ended June 30, 2019 was 55.6%, compared to 60.8% for the six months ended June 30, 2018. This decrease was primarily attributable to the increase in gross profit due to the commencement of commercial operation of the third phase of our McGinness Hills Complex and the gross profit from USG, offset partially by the Puna power plant in Hawaii, for which we recorded cost of revenues with no associated revenues due to the shut-down of the power plant following the Kilauea volcanic eruption in May 3, 2018. The cost of revenues attributable to our international power plants was 24.7% of our Electricity segment cost of revenues.

General and administrative expenses for the six months ended June 30, 2019 were $29.9 million compared to $29.7 million for the six months ended June 30, 2018. General and administrative expenses for the six months ended June 30, 2019 constituted 7.8% of total revenues for such period, compared to 8.2% for the six months ended June 30, 2018.

Operating Income

Operating income for the six months ended June 30, 2019 was $100.6 million, compared to $91.2 million for the six months ended June 30, 2018, which represented an 10.3% increase. The increase in operating income was attributable to the increase in our Electricity segment gross margin, as discussed above, offset by a decrease in our Product segment gross margin. Operating income attributable to our Electricity segment for the six months ended June 30, 2019 was $95.0 million, compared to $73.9 million for the six months ended June 30, 2018. Operating income attributable to our Product segment for the six months ended June 30, 2019 was $9.6 million, compared to $20.3 million for the six months ended June 30, 2018. Operating loss attributable to our Other segment for the six months ended June 30, 2019 was $4.0 million compared to $3.0 million for the six months ended June 30, 2018.

Interest Expense, Net

Interest expense, net for the six months ended June 30, 2019 was $42.7 million, compared to $30.2 million for the six months ended June 30, 2018. This increase was primarily due to (i) $100.0 million and $50.0 million of proceeds from a senior unsecured loan received on March 22, 2018 and March 25, 2019, respectively; (ii) $96.0 million debt as part of the acquisition of USG; (iii) $3.6 million increase in interest related to the sale of tax benefits; (iv) $114.7 million of proceeds from a limited recourse loan received on October 29, 2018 from OPIC for financing the Honduras power plant; and (v) $41.5 million of proceeds from a full recourse loan received on January 4, 2019 from DEG for financing the Kenya power plant, partially offset due to lower interest expense as a result of principal payments of long term debt.

Derivatives and Foreign Currency Transaction Gains (Losses)

Derivatives and foreign currency transaction gains for the six months ended June 30, 2019 were $0.5 million, compared to losses of $2.1 million for the six months ended June 30, 2018. Derivatives and foreign currency transaction gains for the six months ended June 30, 2019 were primarily attributable to gains from foreign currency forward contracts which were not accounted for as hedge transactions. Derivatives and foreign currency transaction losses for the six months ended June 30, 2018 were primarily attributable to losses from foreign currency forward contracts which were not accounted for as hedge transactions.

Income Attributable to Sale of Tax Benefits

Income attributable to the sale of tax benefits for the six months ended June 30, 2019 was $12.4 million, compared to $10.9 million for the six months ended June 30, 2018. This income primarily represents the value of PTCs and taxable income or loss generated by certain of our power plants allocated to investors under tax equity transactions in the six months ended June 30, 2019 compared to the value of PTCs and taxable income allocated to the investors in the six months ended June 30, 2018.

Other Non-Operating Income (Expense), Net

Other non-operating income for the six months ended June 30, 2019 was $1.1 million, compared to $7.4 million for the six months ended June 30, 2018. Other non-operating income for the six months ended June 30, 2019 mainly includes an income of $1.0 million from the sale of PG&E receivables relating to the January 2019 monthly invoice which was not paid as it occurred before PG&E filed for reorganization under Chapter 11 bankruptcy. Other non-operating income for the six months ended June 30, 2018 mainly includes an income of $7.2 million insurance settlement of our Puna power plant rig which was damaged by the Kilauea volcanic eruption.

42

Income Taxes

Income tax provision for the six months ended June 30, 2019 was $10.5 million compared to $2.2 million for the six months ended June 30, 2018. Our effective tax rate for the six months ended June 30, 2019 and June 30, 2018, was 14.5% and 2.8%, respectively. Our effective tax rate is primarily based upon the composition of our income in different countries and changes related to valuation allowances for certain countries. Our aggregate effective tax rate for the six months ended June 30, 2019 differs from the 21% U.S. federal statutory tax rate due to (i) the impact of the recently enacted global intangible low tax income (“GILTI”); (ii) the increase in the valuation allowance on the deferred tax assets related to the limitation on interest expense under the recently enacted IRC section 163(j); (iii) withholding taxes on future dividend distributions; (iv) mix of business in various countries with higher and lower statutory rates than the federal rate; partially offset by forecasted generation of production tax credits and adjustments to previously recorded tax attributes.

See Note 11 to our condensed consolidated financial statements for discussion regarding incremental accounting adjustments related to the Tax Act.

Equity in Earnings (losses) of Investees, Net

Equity in earnings of investees, net for the six months ended June 30, 2019 was $2.2 million, compared to $1.6 million for the six months ended June 30, 2018. Equity in earnings of investees, net is derived from our 12.75% share in the earnings or losses in Sarulla. The increase was mainly attributable to utilization of carryforward losses, offset partially by a decrease in gross margin due well-field issues in the NIL power plant which resulted in low generation. Sarulla is currently developing a remediation plan with a target to increase generation in the near-term back to previous levels. We are following the remediation plans in Sarulla as well as the accounting impact and its implication on our financial statements and our investment in Sarulla.

Net Income

Net income for the six months ended June 30, 2019 was $64.3 million, compared to $76.9 million for the six months ended June 30, 2018, which represents a decrease of $12.6 million. This decrease in net income was primarily attributable to an increase in income tax provision of $8.3 million, an increase of $12.6 million in interest expense, net and a decrease of $6.2 million in other non-operating income, partially offset by an increase of $9.4 million in operating income and an increase of $2.6 million in derivatives and foreign currency transaction gains, as discussed above.

Net Income attributable to the Company’s Stockholders

Net income attributable to the Company’s stockholders for the six months ended June 30, 2019 was $59.9 million, compared to $69.2 million for the six months ended June 30, 2018, which represents a decrease of $9.3 million. This decrease was attributable to the decrease in net income of $12.6 million, offset partially by a decrease of $3.3 million in net income attributable to noncontrolling interest mainly due to the shutdown of the Puna power plant in Hawaii, all as discussed above.

Liquidity and Capital Resources

Our principal sources of liquidity have been derived from cash flows from operations, proceeds from third party debt such as borrowings under our credit facilities, private offerings and issuances of debt securities, project financing, tax monetization transactions, short term borrowing under our lines of credit, and proceeds from the sale of equity interests in one or more of our projects. We have utilized this cash to develop and construct power plants, fund our acquisitions, pay down existing outstanding indebtedness, and meet our other cash and liquidity needs.

As of June 30, 2019, we had access to (i) $110.7 million in cash and cash equivalents, of which $97.4 million is held by our foreign subsidiaries; and (ii) $155.9 million of unused corporate borrowing capacity under existing lines of credit with different commercial banks.

Our estimated capital needs for the remainder of 2019 include between $186.0 million and $206.0 million for capital expenditures on new projects under development or construction, exploration activity, storage activity, investment in our manufacturing facility and operating projects, as well as the cost of new drilling in our Puna power plant that is required to resume operation at its original 38MW generating capacity, with some of these costs to be offset by insurance proceeds. In addition, $79.6 million will be needed for debt repayment, including $38.1 million repayment of short-term revolving lines of credit that we assume will be renewed.

As of June 30, 2019, $227.8 million in the aggregate was outstanding under credit agreements with several banks as described below under “Credit Agreements”.

We expect to finance these requirements with: (i) the sources of liquidity described above; (ii) positive cash flows from our operations; and (iii) future project financings and re-financings (including construction loans and tax equity). Management believes that, based on the current stage of implementation of our strategic plan, the sources of liquidity and capital resources described above will address our anticipated liquidity, capital expenditures, and other investment requirements.

As of June 30, 2019, we have revised our assertion to no longer indefinitely reinvest foreign funds held by our foreign subsidiaries, with the exception of a certain balance held in Israel, and have accrued the incremental foreign withholding taxes. Accordingly, during the six months ended June 30, 2019, we included a foreign income tax expense of $6.6 million related to foreign withholding taxes on accumulated earnings of all of our foreign subsidiaries and an increase to the valuation allowance related to PTC’s of $1.9 million. In addition, a state income tax expense of $ 0.9 million was recorded.

Third-Party Debt

Our third-party debt consists of (i) non-recourse and limited-recourse project finance debt or acquisition financing debt that we or our subsidiaries have obtained for the purpose of developing and constructing, refinancing or acquiring our various projects and (ii) full-recourse debt incurred by us or our subsidiaries for general corporate purposes.

Letters of Credits under the Credit Agreements

Some of our customers require our project subsidiaries to post letters of credit in order to guarantee their respective performance under relevant contracts. We are also required to post letters of credit to secure our obligations under various leases and licenses and may, from time to time, decide to post letters of credit in lieu of cash deposits in reserve accounts under certain financing arrangements. In addition, our subsidiary, Ormat Systems is required from time to time to post performance letters of credit in favor of our customers with respect to orders of products.

Restrictive covenants

Our obligations under the credit agreements, the loan agreements, and the trust instrument governing the bonds described above are unsecured, but we are subject to a negative pledge in favor of the banks and the other lenders and certain other restrictive covenants. These include, among other things, a prohibition on: (i) creating any floating charge or any permanent pledge, charge or lien over our assets without obtaining the prior written approval of the lender; (ii) guaranteeing the liabilities of any third party without obtaining the prior written approval of the lender; and (iii) selling, assigning, transferring, conveying or disposing of all or substantially all of our assets, or a change of control in our ownership structure. Some of the credit agreements, the term loan agreements, and the trust instrument contain cross-default provisions with respect to other material indebtedness owed by us to any third party. In some cases, we have agreed to maintain certain financial ratios, which are measured quarterly, such as: (i) equity of at least $600 million and in no event less than 25% of total assets; (ii) 12-month debt, net of cash, cash equivalents, and short-term bank deposits to Adjusted EBITDA ratio not to exceed 6.0; and (iii) dividend distributions not to exceed 35% of net income in any calendar year. As of June 30, 2019: (i) total equity was $1,491.6 million and the actual equity to total assets ratio was 46.7% and (ii) the 12-month debt, net of cash, cash equivalents, to Adjusted EBITDA ratio was 3.05. During the six months ended June 30, 2019, we distributed interim dividends in an aggregate amount of $11.2 million. The failure to perform or observe any of the covenants set forth in such agreements, subject to various cure periods, would result in the occurrence of an event of default and would enable the lenders to accelerate all amounts due under each such agreement.

45

As described above, we are currently in compliance with our covenants with respect to the credit agreements, the loan agreements and the trust instrument, and believe that the restrictive covenants, financial ratios and other terms of any of our full-recourse bank credit agreements will not materially impact our business plan or operations. 

Future minimum payments

Future minimum payments under long-term obligations, excluding revolving credit lines with commercial banks as of June 30, 2019, are as follows:

	(Dollars in thousands)

 Liquidity Impact of Uncertain Tax Positions

The Company has a liability associated with unrecognized tax benefits and related interest and penalties in the amount of approximately $14.5 million as of June 30, 2019. This liability is included in long-term liabilities in our condensed consolidated balance sheet because we generally do not anticipate that settlement of the liability will require payment of cash within the next twelve months. We are not able to reasonably estimate when we will make any cash payments required to settle this liability.

For the Six Months Ended June 30, 2019

Net cash provided by operating activities for the six months ended June 30, 2019 was $156.1 million, compared to $67.1 million for the six months ended June 30, 2018. The net increase of $89.0 million was primarily due to: (i) a decrease in accounts payable and accrued expenses of $6.2 million in the six months ended June 30, 2019, compared to $54.2 million in the six months ended June 30, 2018, mainly due to: (a) a withholding tax payment of approximately $14 million in the six months ended June 30, 2019 compared to $44 million in the six months ended June 30, 2018 due to a distribution from OSL; and (b) due to timing of payments to our suppliers; and (ii) a net increase of $10.5 million in costs and estimated earnings in excess of billings, net in our Product segment in the six months ended June 30, 2019 compared to a net decrease of $9.7 million in the six months ended June 30, 2018, as a result of timing in billings to our customers.

Net cash used in investing activities for the six months ended June 30, 2019 was $114.2 million, compared to $236.2 million for the six months ended June 30, 2018. The principal factor that affected our net cash used in investing activities during the six months ended June 30, 2019 was capital expenditures of $114.9 million, primarily for our facilities under construction. The principal factors that affected our net cash used in investing activities during the six months ended June 30, 2018 were: (i) capital expenditures of $139.1 million, primarily for our facilities under construction; (ii) cash paid for acquisition of controlling interest in USG, net of cash acquired of $95.1 million; and (iii) an investment in an unconsolidated company of $3.8 million.

Net cash used in financing activities for the six months ended June 30, 2019 was $37.6 million, compared to $188.2 million net cash provided by financing activities for the six months ended June 30, 2018. The principal factors that affected the net cash used in financing activities during the six months ended June 30, 2019 were: (i) net payment of $105.9 million from our revolving credit lines with commercial banks which were used for capital expenditures, (ii) the repayment of long-term debt in the amount of $42.9 million, (iii) a $11.2 million cash dividend payment and (iv) $7.8 million cash paid to a noncontrolling interest, partially offset by (i) $50 million of proceeds from a senior unsecured loan, (ii) $41.5 million of proceeds from a term loan for our Olkaria 3 Complex plant 1 expansion, (iii) $23.5 million of proceeds for the financing of two 20 MW battery energy storage projects, and (iv) $17.8 million of proceeds from a limited and non-recourse loans for our Guadeloupe power plant. The principal factors that affected our net cash used in financing activities during the six months ended June 30, 2018 were: (i) $100.0 million of proceeds from a senior unsecured loan, (ii) net proceeds of $107.1 million from our revolving credit lines with commercial banks, and (iii) proceeds from sale of limited liability company interest in Tungsten, net of transaction costs of $32.4 million, partially offset by (i) the repayment of long-term debt in the amount of $28.3 million, (ii) a $16.7 million cash dividend paid and (iv) $8.0 million cash paid to noncontrolling interest.

Non-GAAP Measures: EBITDA and Adjusted EBITDA

We calculate EBITDA as net income before interest, taxes, depreciation and amortization. We calculate Adjusted EBITDA as net income before interest, taxes, depreciation and amortization, adjusted for (i) termination fees, (ii) impairment of long-lived assets, (iii) write-off of unsuccessful exploration activities, (iv) any mark-to-market gains or losses from accounting for derivatives, (v) merger and acquisition transaction costs, (vi) stock-based compensation, (vii) gains or losses from extinguishment of liability, (viii) gains or losses on sales of subsidiaries and property, plant and equipment and (ix) other unusual or non-recurring items. EBITDA and Adjusted EBITDA are not measurements of financial performance or liquidity under accounting principles generally accepted in the U.S. (U.S. GAAP) and should not be considered as an alternative to cash flow from operating activities or as a measure of liquidity or as an alternative to net earnings as indicators of our operating performance or any other measures of performance derived in accordance with U.S. GAAP. EBITDA and Adjusted EBITDA are presented because we believe they are frequently used by securities analysts, investors and other interested parties in the evaluation of a company’s ability to service and/or incur debt. However, other companies in our industry may calculate EBITDA and Adjusted EBITDA differently than we do.

Net income for the three and six months ended June 30, 2019 was $36.2 million and $64.3 million, respectively, compared to $2.7 million and $76.9 million for the three and six months ended June 30, 2018, respectively.

Adjusted EBITDA for the three and six months ended June 30, 2019 was $94.9 million and $196.6 million compared to $80.8 million and $179.2 million for the three and six months ended June 30, 2018.

The following table reconciles net income to EBITDA and Adjusted EBITDA for the three and six-month periods ended June 30, 2019 and 2018:

In May 2014, the Sarulla closed $1,170.0 million in financing. As of June 30, 2019, the credit facility has an outstanding balance of $1,108.8 million. Our proportionate share in the SOL credit facility is $141.4 million.

Capital Expenditures

Our capital expenditures primarily relate to: (i) the development and construction of new power plants, (ii) the enhancement of our existing power plants; and (iii) investment in activities under our strategic plan.

The following is an overview of projects that are fully released for construction:

Steamboat Hills Power Plant (Nevada). We are planning to replace all of the old power plant equipment with new advanced technology equipment that will eventually increase the capacity by approximately 16 MW and reduce maintenance costs. Procurement and manufacturing are ongoing. Equipment delivery is planned for the third quarter and commercial operation is expected in early 2020.

48

Heber Complex (California). We are currently in the process of repowering the Heber 1 and Heber 2 power plants. We are planning to replace steam turbine and old OEC units with new advanced technology equipment that will add a net capacity of 11 MW. Following these enhancements, we expect the capacity of the complex to reach 92 MW. Permitting, Engineering and procurement are ongoing. Manufacturing is planned for the fourth quarter of 2019 and site construction commenced. We expect commercial operation in early 2021.

In addition, we are in the process of upgrading some of the equipment, such as turbines, pipelines and cooling systems at some of our operating power plants including Ormesa in California, Tuscarora and San Emidio in Nevada, Zunil and Amatitlan in Guatemal Neal Hot Springs in Oregon.

The following is an overview of projects that are in initial stages of construction:

Carson Lake Project. We plan to develop between 10 MW to 15 MW Carson Lake project on Bureau of Land Management (BLM) leases located in Churchill County, Nevada. We drilled one well in 2016 that did not meet our commercial criteria and another in 2017 that tested favorably. Planning is in process for next steps including a flow test to evaluate reservoir volume. We signed a Small Generator Interconnection Agreement with NV Energy in December 2017. As of June 30, 2019, we postponed the drilling activity to next year.

CD 4 Project. We plan to develop a 30 MW project at the Mammoth complex on primarily BLM leases. We have completed two production wells, one of which was previously considered an injection well. We continued drilling in 2018. We signed a Wholesale Distribution Access Tariff Cluster Large Generator Interconnection Agreement with Southern California Edison in December 2017. We recently signed a 25-year PPA with SCPPA for 16 MW that will be sold to the City of Colton in California. We intend to sell the balance of 14MW to other offtakers or at the spot market. We expect commercial operation by the end of 2021.

We have estimated approximately $282.0 million in capital expenditures for construction of new projects and enhancements to our existing power plants, of which we have invested approximately $87.1 million as of June 30, 2019. We expect to invest approximately $105 million of the total amounts during the remainder of 2019 and the remaining of approximately $89.9 million thereafter.

In addition, we estimate approximately $51.0 million in additional capital expenditures in the remainder of 2019 to be allocated as follows: (i) $25.0 million for maintenance capital expenditures to our operating power plants; (ii) $10.0 million for exploration; (iii) $10.0 million for the construction and development of storage projects; (iv) $6.0 million for enhancement to our production facilities

Also, we expect to invest between $30 million and $50 million for well repair and new drilling in our Puna power plant that is required to resume operation at its original 38MW generating capacity. We expect insurance proceeds to recover part of this investment.

In the aggregate, we estimate our total capital expenditures for the remainder of 2019 will be approximately between $186.0 million and $206.0 million including Puna’s repair and drilling.

Exposure to Market Risks

Based on current conditions, we believe that we have sufficient financial resources to fund our activities and execute our business plans. However, the cost of obtaining financing for our project needs may increase significantly or such financing may be difficult to obtain.

We, like other power plant operators, are exposed to electricity price volatility risk. Our exposure to such market risk is currently limited because many of our long-term PPAs (except for the 25 MW PPA for the Puna complex and the between 30 MW and 40 MW PPAs in the aggregate for the Heber 2 power plant in the Heber Complex, and the G2 power plant in the Mammoth Complex) have fixed or escalating rate provisions that limit our exposure to changes in electricity prices.

The energy payments under the PPAs of the Heber 2 power plant in the Heber Complex and the G2 power plant in the Mammoth Complex are determined by reference to the relevant power purchaser’s Short Run Avoided Cost (“SRAC”). A decline in the price of natural gas will result in a decrease in the incremental cost that the power purchaser avoids by not generating its electrical energy needs from natural gas, or by reducing the price of purchasing its electrical energy needs from natural gas power plants, which in turn will reduce the energy payments that we may charge under the relevant PPA for these power plants. The Puna Complex is currently benefiting from energy prices which are higher than the floor under the 25 MW PPA for the Puna Complex as a result of the high fuel costs that impact HELCO’s avoided costs.

As of June 30, 2019, 95.8% of our consolidated long-term debt was fixed rate debt and therefore was not subject to interest rate volatility risk. As of such date, 4.2% of our long-term debt was floating rate debt, exposing us to interest rate risk in connection therewith. As of June 30, 2019, $51.2 million of our long-term debt remained subject to interest rate risk.

We currently maintain our surplus cash in short-term, interest-bearing bank deposits, money market securities and commercial paper (with a minimum investment grade rating of AA by Standard & Poor’s Ratings Services).

49

Our cash equivalents are subject to interest rate risk. Fixed rate securities may have their market value adversely impacted by a rise in interest rates, while floating rate securities may produce less income than expected if interest rates fall. As a result of these factors, our future investment income may fall short of expectations because of changes in interest rates or we may suffer losses in principal if we are forced to sell securities that decline in market value because of changes in interest rates.

We are also exposed to foreign currency exchange risk, in particular the fluctuation of the U.S. dollar versus the Israeli shekel and euro. Risks attributable to fluctuations in currency exchange rates can arise when we or any of our foreign subsidiaries borrow funds or incur operating or other expenses in one type of currency but receive revenues in another. In such cases, an adverse change in exchange rates can reduce such subsidiary’s ability to meet its debt service obligations, reduce the amount of cash and income we receive from such foreign subsidiary, or increase such subsidiary’s overall expenses. Risks attributable to fluctuations in foreign currency exchange rates can also arise when the currency denomination of a particular contract is not the U.S. dollar. Substantially all of our PPAs in the international markets are either U.S. dollar-denominated or linked to the U.S. dollar except for our operations on Guadeloupe, where we own and operate the Boulliante power plant which sells its power under a Euro-denominated PPA with Électricité de France S.A. Our construction contracts from time to time contemplate costs which are incurred in local currencies. The way we often mitigate such risk is to receive part of the proceeds from the contract in the currency in which the expenses are incurred. Currently, we have forward contracts in place to reduce our foreign currency exposure and expect to continue to use currency exchange and other derivative instruments to the extent we deem such instruments to be the appropriate tool for managing such exposure. We do not believe that our exchange rate exposure has or will have a material adverse effect on our financial condition, results of operations or cash flows.

We performed a sensitivity analysis on the fair values of our long-term debt obligations, and foreign currency exchange forward contracts. The foreign currency exchange forward contracts listed below principally relate to trading activities. The sensitivity analysis involved increasing and decreasing forward rates at June 30, 2019 and December 31, 2018 by a hypothetical 10% and calculating the resulting change in the fair values.

At this time, the development of our strategic plan has not exposed us to any additional market risk. However, as the implementation of the plan progresses, we may be exposed to additional or different market risks.

The results of the sensitivity analysis calculations as of June 30, 2019 and December 31, 2018 are presented below:

In July 2017, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR (London Interbank Offered Rate), announced that it intends to phase out LIBOR by the end of 2021. It is unclear whether or not LIBOR will cease to exist at that time and/or whether new methods of calculating LIBOR will be established such that it will continue to exist after 2021. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, is considering replacing U.S. dollar LIBOR with a new SOFR (Secured Overnight Financing Rate) index calculated by short-term repurchase agreements, backed by Treasury securities.

The Company has evaluated the impact of the transition from LIBOR, and currently believes that the transition will not have a material impact on its consolidated financial statements.

Effect of Inflation

We do not expect that inflation will be a significant risk in the near term, given the current global economic conditions, however, that could change in the future. To address rising inflation, some of our contracts include certain provisions that mitigate inflation risk.

In connection with the Electricity segment, none of our U.S. PPAs, including the SCPPA Portfolio PPA, are directly linked to the Consumer Price Index (CPI). Inflation may directly impact an expense we incur for the operation of our projects, thereby increasing our overall operating costs and reducing our profit and gross margin. The negative impact of inflation may be partially offset by price adjustments built into some of our PPAs that could be triggered upon such occurrences. The energy payments pursuant to our PPAs for some of our power plants such as the Brady power plant, the Steamboat 2 and 3 power plants and the McGinness Complex increase every year through the end of the relevant terms of such agreements, though such increases are not directly linked to the CPI or any other inflationary index. Lease payments are generally fixed, while royalty payments are generally calculated as a percentage of revenues and therefore are not significantly impacted by inflation. In our Product segment, inflation may directly impact fixed and variable costs incurred in the construction of our power plants, thereby increasing our operating costs in the Product segment. We are more likely to be able to offset all or part of this inflationary impact through our project pricing. With respect to power plants that we build for our own electricity production, inflationary pricing may impact our operating costs which may be partially offset in the pricing of the new long-term PPAs that we negotiate.

Concentration of Credit Risk

Our credit risk is currently concentrated with the following major customers: Sierra Pacific Power Company and Nevada Power Company (subsidiaries of NV Energy), SCPPA and Kenya Power and Lighting Company (KPLC). If any of these electric utilities fail to make payments under its PPAs with us, such failure would have a material adverse impact on our financial condition. Also, by implementing our multi-year strategic plan we may be exposed, by expanding our customer base, to different credit profile customers than our current customers.

Sierra Pacific Power Company and Nevada Power Company accounted for 16.5% and 17.0% of Total Revenues for the three months ended June 30, 2019 and 2018, respectively, and for 17.3% and 16.7% for the six months ended June 30, 2019 and 2018, respectively.

SCPPA accounted for 17.2% and 14.9% of Total Revenues for the three months ended June 30, 2019 and 2018, respectively, and for 18.3% and 15.6% for the six months ended June 30, 2019 and 2018, respectively.

KPLC accounted for 16.6% and 16.6% of Total Revenues for the three months ended June 30, 2019 and 2018, respectively, and 16.0% and 15.8% for the six months ended June 30, 2019 and 2018, respectively.

We have historically been able to collect on substantially all of our receivable balances. As of June 30, 2019, the amounts overdue from KPLC in Kenya were $34.5 million of which $10.5 million was paid in July 2019 and $5.9 million in August 2019. These amounts represent an average of 54 days overdue. In Honduras, we continue to see deterioration in the collection from ENEE and as of June 30, 2019, the amount overdue is $20.1 million of which $3.1 million was paid in August 2019. These amounts represent an average of 108 days, an increase of 18 days from March 31, 2019. Due to the obligation of the Honduran government to support us, the Company believes it will be able to collect all past due amounts, and therefore no provision for doubtful accounts has been recorded.

Government Grants and Tax Benefits

A comprehensive discussion on government grants and tax benefits is included in our 2018 Annual Report. There have been no material changes to this section in the six months ended June 30, 2019.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The information appearing under the headings “Exposure to Market Risks” and “Concentration of Credit Risk” in Part I, Item 2 of this quarterly report on Form 10-Q is incorporated by reference herein.

ITEM 4. CONTROLS AND PROCEDURES

a. Evaluation of disclosure controls and procedures

Our management, including our Chief Executive Officer and Chief Financial Officer, has conducted the evaluation of the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) required by Rules 13a-15(b) or 15d-15(b) under the Exchange Act, as amended. Based upon that evaluation, as a result of the material weakness in internal control over financial reporting described below, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of June 30, 2019 to ensure that information required to be disclosed in the reports that we file under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure.

Previously Identified Material Weakness in Internal Control Over Financial Reporting

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

We previously disclosed in our 2018 and 2017 Annual Reports the following material weakness which still existed as of June 30, 2019. In connection with the change in our repatriation strategy and the related release of the U.S. income tax valuation allowance in the second quarter of 2017, we did not perform an effective risk assessment related to our internal controls over the accounting for income taxes.  As a result, we identified a deficiency in the design of our internal control over financial reporting related to our accounting for income taxes, which resulted in the restatements of the Company’s unaudited condensed consolidated financial statements for the three and six months ended June 30, 2017, the three and nine months ended September 30, 2017, and the restatement of the Company’s consolidated financial statements for the year ended December 31, 2017. Additionally, this control deficiency could result in a misstatement of the aforementioned balances and disclosures that would result in a material misstatement to the interim or annual consolidated financial statements that would not be prevented or detected. Our management has concluded that this deficiency constitutes a material weakness in our internal control over financial reporting.

Remediation Plan for Material Weakness

Subsequent to the evaluation made in connection with filing our Amended Annual Report on Form 10-K for the year ended December 31, 2017, our management, with the oversight of the Audit Committee of the Board of Directors, has continued the process of remediating the material weakness. In connection with the remediation process, we have:

● performed an enhanced risk assessment related to our internal controls over the accounting for income taxes;

● recruited additional tax personnel throughout the year, including a VP of Tax in January 2019;

● engaged an external tax and accounting firm to prepare and review our annual and quarterly income tax provision;

● implemented specific control procedures for the review, analysis and reporting of our income tax accounts, including control procedures of projections that support the deferred tax assets and liabilities;

● strengthened our income tax controls with improved documentation, communication and oversight.

We have made substantial progress in accordance with our remediation plan. However, the material weakness will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. We are committed to continuing to improve our internal control processes and will continue to review, optimize and enhance our financial reporting controls and procedures, however, there can be no assurance that this will occur within 2019. 

b.  Changes in internal control over financial reporting

There were no changes in our internal controls over financial reporting in the second quarter of 2019 that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

Plumstriker Loan 

On May 4, 2019, a wholly owned indirect subsidiary of the Company (“Plumstriker”) and its two subsidiaries entered into a $23.5 million loan agreement with a U.S. financing division of a leading global industrial company for the financing of two 20 MW battery energy storage projects located in New Jersey. On May 30, 2019, Plumstriker completed the drawdown of the full loan amount, bearing interest of three months U.S. Libor plus 3.5% margin. The loan will be repaid in 29 equal quarterly principal installments of 1.25% of the loan, and additional 14 unequal semi-annual principal payments, commencing June 30, 2019. The final maturity date of the loan is May 30, 2026. Proceeds of the loan were used to refinance investments in the said projects. The debt repayment of the loan is not guaranteed by the Company or any of its other subsidiaries.

Société Géneralé Loan

On April 9, 2019, an indirect subsidiary of the Company (“Guadeloupe”), entered into a $8.9 million loan agreement with Société Général. On April 29, 2019, Guadeloupe completed the drawdown of the full loan amount of the loan, bearing a fixed interest of 1.52%. The loan will be repaid in 28 quarterly principal installments, commencing July 29, 2019. The final maturity date of the loan is April 29, 2026. The loan has a limited guarantee by one of the Company’s subsidiary.

Bpifrance Loan

On April 4, 2019, Guadeloupe, entered into a $8.9 million loan agreement with Banque Publique d’Investissement ("Bpifrance"). On April 29, 2019, Guadeloupe completed the drawdown of the full loan amount, bearing a fixed interest of 1.93%. The loan will be repaid in 20 equal quarterly principal installments, commencing June 30, 2021. The final maturity date of the loan is March 31, 2026. The loan is not guaranteed by the Company or any of its other subsidiaries.

Puna

On May 3, 2018, the Kilauea volcano located in close proximity to our Puna 38 MW geothermal power plant in the Puna district of Hawaii's Big Island erupted following a significant increase in seismic activity in the area. Before it stopped flowing, the lava covered the wellheads of three geothermal wells, monitoring wells and the substation of the Puna complex and an adjacent warehouse that stored a drilling rig that was also consumed by the lava. The insurance policy coverage for property and business interruption is provided by a consortium of insurers. All the insurers accepted and started paying for the costs to rebuild the destroyed substation, and during the first quarter of 2019, the Company received an additional $1.5 million of such proceeds. However, only some of the insurers accepted that the business interruption coverage started in May 2018 and during the first and second quarters of 2019, the Company received and recorded an additional $8.1 million of such proceeds which were included under cost of revenues in the condensed consolidated statements of operations and comprehensive income for the six months ended June 30, 2019. The Company is still in discussions to reach an understanding with all insurers to start paying for the business interruption as of May 2018. The Company is still assessing the damages in the Puna facilities and continues to coordinate with Hawaii Electric Light Company (“HELCO”) and local authorities to bring the power plant back to operation.

As of August 2019, the Company continues to make good progress in the efforts to resume the operation at the Puna power plant. The Company expects that the plant refurbishment activities will be completed on schedule by the end of 2019 and that the plant will resume operations as soon as the local permitting and transmission network upgrades being undertaken by our local utility partner are completed in early 2020. In the well field area, during work to remove the plugs from the geothermal wells the Company found that two of the production wells were damaged and it will have to repair them or drill a new well. In addition, some of the other production wells at the Puna power plant need to be cleaned out. Once Puna resumes operation, the Company will gradually increase the power plant generating capacity as it completes the necessary repairs and drilling.

The Company continues to assess the accounting implications of this event on the assets and liabilities on its balance sheet and whether an impairment will be required. Any significant damage to the geothermal resource or continued shut-down following the lava event at the Puna facilities could have an adverse impact on the power plant's electricity generation and availability, which in turn could have a material adverse impact on our business and results of operations. 

DEG 3 Loan

On January 4, 2019, an indirect subsidiary of the Company (“OrPower 4”) entered into an additional $41.5 million subordinated loan agreement with Deutsche Investitions-und Entwicklungsgesellschaft mbH ("DEG") (the “DEG 3 Loan Agreement”) and on February 28, 2019, OrPower 4 completed a drawdown of the full loan amount, with a fixed interest rate of 6.04% for the duration of the loan (the “DEG 3 Loan”). The DEG 3 Loan will be repaid in 19 equal semi-annual principal installments commencing June 21, 2019, with a final maturity date of  June 21, 2028. Proceeds of the DEG 3 Loan were used by OrPower 4 to refinance upgrades to Plant 1 of the Olkaria III Complex, which were originally financed using equity. The DEG 3 Loan is subordinated to the senior loan provided by Overseas Private Investment Corporation (“OPIC”) for Plants 1-3 of the Olkaria III Complex. The DEG 3 Loan is guaranteed by the Company.

Migdal Senior Unsecured Loan

On March 25, 2019, the Company entered into a first addendum (“First Addendum”) to the loan agreement (the "Migdal Loan Agreement") with Migdal Insurance Company Ltd., Migdal Makefet Pension and Provident Funds Ltd. and Yozma Pension Fund of Self-Employed Ltd., all entities within the Migdal Group, a leading insurance company and institutional investor in Israel dated March 22, 2018. The First Addendum provides for an additional loan by the lenders to the Company in an aggregate principal amount of $50.0 million (the “Additional Migdal Loan”). The Additional Migdal Loan will be repaid in 15 semi-annual payments of $2.1 million each, commencing on September 15, 2021, with a final payment of $18.5 million on March 15, 2029. The Additional Migdal Loan bears interest at a fixed rate of 4.6% per annum, payable semi-annually, subject to adjustment in certain circumstances as described below.

The Additional Migdal Loan was entered into under substantially the same terms and conditions of the Migdal Loan Agreement as disclosed in the Company’s Form 10-K for the year ended December 31, 2018.

Write-offs of unsuccessful exploration activities

There were no write-offs of unsuccessful exploration activities for the three and six months ended June 30, 2019. Write-offs of unsuccessful exploration activities for the three and six months ended June 30, 2018 were $0 and $0.1 million, respectively.

Reconciliation of Cash and cash equivalents and Restricted cash and cash equivalents

The following table provides a reconciliation of Cash and cash equivalents and Restricted cash and cash equivalents as reported on the balance sheet to the total of the same amounts shown on the statement of cash flows:

	June 30,		December 31,		June 30,
	2019		2018		2018
	(Dollars in thousands)
Cash and cash equivalents	$	110,665	$	98,802	$	66,696
Restricted cash and cash equivalents		70,974		78,693		76,041
Total Cash and cash equivalents and restricted cash and cash equivalents	$	181,639	$	177,495	$	142,737

Concentration of credit risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of temporary cash investments and accounts receivable.

The Company places its temporary cash investments with high credit quality financial institutions located in the United States (“U.S.”) and in foreign countries. At June 30, 2019 and December 31, 2018, the Company had deposits totaling $44.1 million and $31.3 million, respectively, in ten U.S. financial institutions that were federally insured up to $250,000 per account. At June 30, 2019 and December 31, 2018, the Company’s deposits in foreign countries amounted to approximately $79.4 million and $93.9 million, respectively.

At June 30, 2019 and December 31, 2018, accounts receivable related to operations in foreign countries amounted to approximately $107.4 million and $102.0 million, respectively. At June 30, 2019 and December 31, 2018, accounts receivable from the Company’s primary customers amounted to approximately 56% and 56% of the Company’s accounts receivable, respectively.

Sierra Pacific Power Company and Nevada Power Company (subsidiaries of NV Energy, Inc.) accounted for 16.5% and 17.0% of the Company’s total revenues for the three months ended June 30, 2019 and 2018, respectively, and 17.3% and 16.7% of the Company’s total revenues for the six months ended June 30, 2019 and 2018, respectively.

Southern California Public Power Authority (“SCPPA”) accounted for 17.2% and 14.9% of the Company’s total revenues for the three months ended June 30, 2019 and 2018, respectively, and 18.3% and 15.6% of the Company’s total revenues for the six months ended June 30, 2019 and 2018, respectively.

Kenya Power and Lighting Co. Ltd. accounted for 16.6% and 16.6% of the Company’s total revenues for the three months ended June 30, 2019 and 2018, respectively, and 16.0% and 15.8% of the Company’s total revenues for the six months ended June 30, 2019 and 2018, respectively.

The Company has historically been able to collect on substantially all of its receivable balances. As of June 30, 2019, the amount overdue from KPLC in Kenya was $34.5 million of which $10.5 million was paid in July 2019 and $5.9 million in August 2019. These amounts represent an average of 54 days overdue. In Honduras, we continue to see deterioration in the collection from Empresa Nacional de Energía Eléctrica (“ENEE”) and as of June 30, 2019, the amount overdue is $20.1 million of which $3.1 million was paid in August 2019. These amounts represent an average of 108 days, an increase of 18 days from March 31, 2019. Due to obligations of the Honduran government to support the Company, the Company believes it will be able to collect all past due amounts, and therefore no provision for doubtful accounts has been recorded.

Additionally, Pacific Gas and Electric Corporation (“PG&E Corporation”) and its subsidiary Pacific Gas and Electric Company (“PG&E”), which accounts for 1.0% and 1.2% of our total revenues for the three and six months ended June 30, 2019, are facing extraordinary challenges relating to a series of catastrophic wildfires that occurred in Northern California in 2017 and 2018. As a result, on January 29, 2019, PG&E Corporation and its subsidiary, PG&E, voluntarily filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code. The Company is closely monitoring its PG&E balance to ensure cash receipts are received timely each month.

Revenues from Contracts with Customers

Contract assets related to our Product segment reflect revenue recognized and performance obligations satisfied in advance of customer billing. Contract liabilities related to the Company’s Product segment reflect payments received in advance of the satisfaction of performance under the contract. The Company receives payments from customers based on the terms established in the contracts. Total contract assets and contract liabilities as of June 30, 2019 and December 31, 2018 are as follows:

	June 30,			December 31,
	2019			2018
	(Dollars in thousands)
Contract assets (*)	$	27,352		$	42,130
Contract liabilities (*)		(14,130	)		(18,402	)
Contract assets, net	$	13,222		$	23,728

(*) Contract assets and contract liabilities are presented as "Costs and estimated earnings in excess of billings on uncompleted contracts" and "Billings in excess of costs and estimated earnings on uncompleted contracts", respectively, on the consolidated balance sheets.

On June 30, 2019, the Company had approximately $182.3 million of remaining performance obligations not yet satisfied or partly satisfied related to our Product segment. The Company expects to recognize approximately 100% of this amount as Product revenues during the next 24 months.

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]

NOTE 2 — NEW ACCOUNTING PRONOUNCEMENTS

New accounting pronouncements effective in the six-month period ended June 30, 2019

Leases

 In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This new standard introduced a number of changes and simplified previous guidance, primarily the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases. The new standard retained the distinction between finance leases and operating leases and the classification criteria between the two types remains substantially similar. Also, lessor accounting remained largely unchanged from previous guidance. However, key aspects of the new standard were aligned with the revenue recognition guidance in Topic 606. Additionally, the new standard defined a lease as a contract, or part of a contract, that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Control over the use of the identified asset means that the customer has both (a) the right to obtain substantially all of the economic benefits from the use of the asset and (b) the right to direct the use of the asset. The Company adopted this new standard as of January 1, 2019 using the modified retrospective approach and accordingly recognized a cumulative-effect adjustment to the opening balance of retained earnings, which was an immaterial amount, with no restatement of comparative information.

In accordance with the new standard, for agreements in which the Company is the lessee, the Company applies a unified accounting model by which it recognizes a right-of-use asset ("ROU") and a lease liability at the commencement date of the lease contract for all the leases in which the Company has a right to control identified assets for a specified period of time. The classification of the lease as a finance lease or an operating lease determines the subsequent accounting for the lease arrangement.

Upon the adoption of the new standard the Company, both as a lessee and as a lessor, chose to apply the following permitted practical expedients:

1. Not reassess whether any existing contracts are or contain a lease;

2. Not reassess the classification of leases that commenced before the effective date (for example, all existing leases that were classified as operating leases in accordance with Topic 840 will continue to be classified as operating leases, and all existing leases that were classified as capital leases in accordance with Topic 840 will continue to be classified as finance leases);

3. Exclude initial direct costs from measurement of the ROU asset at the date of initial application;

4. Applying the practical expedient (for a lessor) to not separate non-lease components accounted for under Topic 606 from lease components and, instead, to account for each separate lease component and the non-lease components associated with that lease component as a single component. If the non-lease components are the predominant components, the Company will account for the combined component as a single performance obligation entirely in accordance with Topic 606. Otherwise, the combined component will be accounted as an operating lease entirely in accordance with the new standard.

5. Applying the practical expedient (for a lessee) regarding the recognition and measurement of short-term leases, for leases for a period of up to 12 months from the commencement date. Instead, the company will continue to recognize the lease payments for those leases in profit or loss on a straight-line basis over the lease term.

Since the Company elected to apply the practical expedients above, it applied the new standard to all contracts entered into before January 1, 2019 and identified as leases in accordance with Topic 840.

The new significant accounting policies regarding leases that were applied as from January 1, 2019 following the application of the new standard are as follows:

1.     Determining whether an arrangement contains a lease

On the inception date of the lease, the Company determines whether the arrangement is a lease or contains a lease, while examining if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

2.     The Company as a lessee

a.  Lease classification:

At the commencement date, a lease is a finance lease if it meets any one of the criteria below; otherwise the lease is an operating lease:

● The lease transfers ownership of the underlying asset to the lessee by the end of the lease term.

● The lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise.

● The lease term is for the major part of the remaining economic life of the underlying asset.

● The present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already reflected in the lease payments equals or exceeds substantially all of the fair value of the underlying asset.

● The underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of lease term.

b. Leased assets and lease liabilities - initial recognition

Upon initial recognition, the Company recognizes a liability at the present value of the lease payments to be made over the lease term, and concurrently recognizes a ROU asset at the same amount of the liability, adjusted for any prepaid or accrued lease payments, plus initial direct costs incurred in respect of the lease.

Since the interest rate implicit in the lease is not readily determinable, the incremental borrowing rate of the Company is used. The subsequent measurement depends of whether the lease is classified as a finance lease or an operating lease.

c.     The lease term

The lease term is the non-cancellable period of the lease plus periods covered by an extension or termination option if it is reasonably certain that the Company will exercise the option.

d.     Subsequent measurement of operating leases

After lease commencement, the Company measures the lease liability at the present value of the remaining lease payments using the discount rate determined at lease commencement (as long as the discount rate hasn’t been updated as a result of a reassessment event).

The Company subsequently measures the ROU asset at the present value of the remaining lease payments, adjusted for the remaining balance of any lease incentives received, any cumulative prepaid or accrued rent if the lease payments are uneven throughout the lease term and any unamortized initial direct costs.

Further, the Company will recognize lease expense on a straight-line basis over the lease term.

e.     Subsequent measurement of finance leases

After lease commencement, the Company measures the lease liability by increasing the carrying amount to reflect interest on the lease liability and reducing the carrying amount to reflect the lease payments made during the period. The Company shall determine the interest on the lease liability in each period during the lease term as the amount that produces a constant periodic discount rate on the remaining balance of the liability, taking into consideration the reassessment requirements.

After lease commencement, the Company measures the ROU assets at cost less any accumulated amortization and any accumulated impairment losses, taking into consideration the reassessment requirements. The Company amortizes the ROU asset on a straight-line basis, unless another systematic basis better represents the pattern in which the Company expects to consume the ROU asset’s future economic benefits. The ROU asset is amortized over the shorter of the lease term or the useful life of the ROU asset as follows:

	(in years)
Land		1	-	35
Automobiles			5
Building			15

The total periodic expense (the sum of interest and amortization expense) of a finance lease is typically higher in the early periods and lower in the later periods.

f.      Variable lease payments:

Variable lease payments that depend on an index or a rate

On the commencement date, the lease payments shall include variable lease payments that depend on an index or a rate (such as the Consumer Price Index or a market interest rate), initially measured using the index or rate at the commencement date. The Company does not remeasure the lease liability for changes in future lease payments arising from changes in an index or rate unless the lease liability is remeasured for another reason. Therefore, after initial recognition, such variable lease payments are recognized in profit or loss as they are incurred.

Other variable lease payments:

Variable payments that depends on performance or use of the underlying asset are not included in the lease payments. Such variable payments are recognized in profit or loss in the period in which the event or condition that triggers the payment occurs.

3.     The Company as a lessor

At lease commencement, the Company as a lessor classifies leases as either finance or operating leases. Finance leases are further classified as a sales-type lease or as a direct financing lease. Under an operating lease, the Company recognizes the lease payment as income over the lease term, generally on a straight-line basis or as earned.

4. Impact of the new standard

a) Effects of the initial application of the new standard on the Company's consolidated balance sheets statement as of January 1, 2019:

	According to the previous accounting policy		The change			As presented according to Topic 842
	(Dollars in thousands)
As of January 1, 2019:
Prepaid expenses and other	$	51,441	$	(35,385	)	$	16,056
Deferred financing and lease costs, net		3,242		(1,659	)		1,583
Property, plant and equipment, net		1,959,578		(12,855	)		1,946,723
Operating leases right of use		-		62,244			62,244
Finance leases right of use		-		13,476			13,476
Accounts payable and accrued expenses		116,362		(2,860	)		113,502
Current maturity of operating lease liabilities		-		7,532			7,532
Current maturity of finance lease liabilities		-		2,841			2,841
Other long-term liabilities		16,087		(9,970	)		6,117
Long term portion of operation lease liabilities		-		17,668			17,668
Long term portion of finance lease liabilities		-		10,668			10,668
Retained earnings		422,222		(58	)		422,164

The Operating leases right of use is higher than the related lease liabilities as a result of prepayments of leases, including the Puna lease and deferred financing lease costs.

b) A weighted-average nominal incremental interest rate of 5% and 7% was used to discount future lease payments in the calculation of the lease liabilities in respect of operating leases and in respect of finance leases, respectively.

Derivatives and Hedging

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. The amendments in this update better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. To meet that objective, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The adoption of this guidance did not have an impact on the Company’s consolidated financial statements.

Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income

In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220). The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). The guidance is effective for the fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The adoption of this guidance did not have an impact on the Company’s consolidated financial statements.

New accounting pronouncements effective in future periods

Financial Instruments—Credit Losses

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments—Credit Losses—Measurement of Credit Losses on Financial Instruments.” This guidance replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance will be effective beginning on January 1, 2020, including interim periods within that year. The Company is currently evaluating the potential effect on its consolidated financial statements.

Note 5 - Fair Value of Financial Instruments

Fair Value Disclosures [Text Block]

NOTE 5— FAIR VALUE OF FINANCIAL INSTRUMENTS

The fair value measurement guidance clarifies that fair value is an exit price, representing the amount that would be received upon selling an asset or paid upon transferring a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under the fair value measurement guidance are described below:

Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities.

Level 2 — Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3 — Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

The following table sets forth certain fair value information at June 30, 2019 and December 31, 2018 for financial assets and liabilities measured at fair value by level within the fair value hierarchy, as well as cost or amortized cost. As required by the fair value measurement guidance, assets and liabilities are classified in their entirety based on the lowest level of inputs that is significant to the fair value measurement.

⁽¹⁾ These amounts relate to contingent receivables and payables relating to acquisition of the Guadeloupe power plant, valued primarily based on unobservable inputs and are included within “Prepaid expenses and other”, “Accounts payable and accrued expenses” and “Other long-term liabilities” on June 30, 2019 and December 31, 2018 in the consolidated balance sheets with the corresponding gain or loss being recognized within Derivatives and foreign currency transaction gains (losses) in the consolidated statement of operations and comprehensive income.

⁽²⁾ These amounts relate to currency forward contracts valued primarily based on observable inputs, including forward and spot prices for currencies, net of contracted rates and then multiplied by notional amounts, and are included within “Prepaid expenses and other” and “Accounts payable and accrued expenses”, as applicable, on June 30, 2019 and December 31, 2018, in the consolidated balance sheet with the corresponding gain or loss being recognized within “Derivatives and foreign currency transaction gains (losses)” in the consolidated statement of operations and comprehensive income.

The amounts set forth in the tables above include investments in debt instruments and money market funds (which are included in cash equivalents). Those securities and deposits are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in an active market. 

The following table presents the amounts of gain (loss) recognized in the consolidated statements of operations and comprehensive income on derivative instruments not designated as hedges (in thousands):

		Amount of recognized gain (loss)

The foregoing forward transactions were not designated as hedge transactions and are marked to market with the corresponding gains or losses recognized within “Derivatives and foreign currency transaction gains (losses)”.

There were no transfers of assets or liabilities between Level 1, Level 2 and Level 3 during the six months ended June 30, 2019.

The fair value of the long-term debt is determined by a valuation model, which is based on a conventional discounted cash flow methodology and utilizes assumptions of current borrowing rates. The fair value of revolving lines of credit is determined using a comparison of market-based price sources that are reflective of similar credit ratings to those of the Company.

The carrying value of financial instruments such as revolving lines of credit and deposits approximates fair value.

Earnings Per Share [Text Block]

NOTE 8 — EARNINGS PER SHARE

Basic earnings per share attributable to the Company’s stockholders is computed by dividing net income or loss attributable to the Company’s stockholders by the weighted average number of shares of common stock outstanding for the period. The Company does not have any equity instruments that are dilutive, except for employee stock-based awards.

The table below shows the reconciliation of the number of shares used in the computation of basic and diluted earnings per share (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Weighted average number of shares used in computation of basic earnings per share		50,800		50,623		50,757		50,618

Weighted average number of shares used in computation of diluted earnings per share		51,094		50,958		51,058		51,001

The number of stock-based awards that could potentially dilute future earnings per share and that were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive was 174,334 and 232,925 for the three months ended June 30, 2019 and 2018, respectively, and 228,775 and 223,708 for the six months ended June 30, 2019 and 2018, respectively.

Segment Reporting Disclosure [Text Block]

NOTE 9 — BUSINESS SEGMENTS

The Company has three reporting segments: the Electricity segment, the Product segment and the Other segment. These segments are managed and reported separately as each offers different products and serves different markets. The Electricity segment is engaged in the sale of electricity from the Company’s power plants pursuant to PPAs. The Product segment is engaged in the manufacture, including design and development, of turbines and power units for the supply of electrical energy and in the associated construction of power plants utilizing the power units manufactured by the Company to supply energy from geothermal fields and other alternative energy sources. The Other segment is engaged in management of curtailable customer loads under contracts with U.S. retail energy providers and directly with large commercial and industrial customers as well as battery storage as a service ("BSAAS"). Under this segment, we provide energy storage, demand response and energy management related services through our Viridity Energy Solutions Inc. ("Viridity") business.

Transfer prices between the operating segments are determined based on current market values or cost-plus markup of the seller’s business segment.

NOTE 10 — COMMITMENTS AND CONTINGENCIES

● On May 21, 2018, a motion to certify a class action was filed in Tel Aviv District Court against Ormat Technologies, Inc. and 11 officers and directors.  The alleged class is defined as "All persons who purchased Ormat shares on the Tel Aviv Stock Exchange between August 3, 2017 and May 13, 2018". The motion alleges that the Company violated  Sections 31(a)(1) and 38C of the Israeli Securities Law because it allegedly: (1) misled investors by stating in its financial statements that it maintains effective internal controls over its accounting policies and procedures, however the Company's internal controls had material weaknesses which led to erroneous accounting in its 2017 unaudited quarterly reports that had to be restated, including adjustments to the Company’s net income and shareholders’ equity; and (2) failed to issue an immediate report in Israel until May 16, 2018, analogous to the report that was released in the United States on May 11, 2018 stating, inter alia, that the errors in its financial reports affected its balance sheet and would be remedied in its 2017 annual report. The Company filed an agreed motion to the Tel Aviv District Court to stay the proceedings in Israel until a final decision in the US case (Mac Costas) is adjudicated.

● On June 11, 2018, a putative class action was filed by Mac Costas on behalf of alleged shareholders that purchased or acquired the Company's ordinary shares between August 8, 2017 and May 15, 2018 was commenced in the United States District Court for the District of Nevada against the Company and its Chief Executive Officer and Chief Financial Officer.  The complaint asserts claim against all defendants pursuant to Section 10(b) of the Exchange Act, as amended, and Rule 10b-5 thereunder and against its officers pursuant to Section 20(a) of the Exchange Act.  The complaint alleges that the Company's Form 10-K for the years ended December 31, 2016 and 2017, and Form 10-Qs for each of the quarters in the nine months ended September 30, 2017 contained material misstatements or omissions, among other things, with respect to the Company’s tax provisions and the effectiveness of its internal control over financial reporting, and that, as a result of such alleged misstatements and omissions, the plaintiffs suffered damages. Following the Mac Costas filing and in accordance with the terms of the Private Securities Litigation Reform Act of 1995 (“PSLRA”), a number of law firms filed applications on behalf of entities purporting to hold shares in the Company, seeking to be appointed as lead plaintiff and lead counsel in the action. On March 12, 2019 the court appointed Phoenix Insurance Company Ltd. (“Phoenix Insurance”) as lead plaintiff and approved their selection of lead counsel. Pursuant to a scheduling stipulation entered between the parties, Phoenix Insurance timely filed its consolidated amended complaint, and the Company has timely filed its motion to dismiss. Under the scheduling stipulation, Phoenix Insurance must file their Opposition by August 26, 2019, and the Company must file their reply by September 25, 2019. The Company believes that it has valid defenses under law and intends to defend itself vigorously. 

● On September 11, 2018, the Klein derivative action (“Klein Action”) was filed against the Company, our board and our Chief Executive Officer and Chief Financial Officer in the United States District Court for the District of Nevada, and on October 22, 2018, the Matthew derivative action (“Matthew Action”) was filed against the company, certain named present and former board members (Barniv, Beck, Boehm, Clark, Falk, Freedland, Granot, Joyal, Nishigori, Sharir, Stern and Wong) in the US District Court, District of Nevada.  The Klein complaint asserts four derivative causes of action generally arising from Ormat's restatement of its financial statements: (i) the individual defendants allegedly breached their fiduciary duties by allowing the company to improperly report its financials; (ii) the individual defendants allegedly were unjustly enriched by being compensated while breaching their fiduciary duties; (iii) the individual defendants allegedly committed corporate waste in paying officers and directors and by incurring legal costs and potential liability; and (iv) the director defendants allegedly breached Section 14(a) of the Exchange Act in connection with the issuance of 2018 proxy. The Matthew complaint similarly alleges derivatively a breach of fiduciary duties, abuse of control, gross mismanagement, and corporate waste by the named directors. On January 24, 2019, the Nevada Court entered an order consolidating the Klein Action and Matthew Action, and staying all deadlines and hearings in the consolidated action pending entry of an order on the motion to dismiss in the Mac Costas putative class action. Within thirty days of entry of an order on the motion to dismiss in the Mac Costas putative class action, the parties are required to meet and confer and to submit a proposed schedule for further proceedings in the consolidated action.

● Following the announcement of the Company’s acquisition of U.S. Geothermal Inc. (“USG”), a number of putative shareholder class action complaints were initially filed on behalf of USG shareholders between March 8, 2018 and March 30, 2018 against USG and the individual members of the USG board of directors.  All of the purported class action suits filed in Federal Court in Idaho have been voluntarily dismissed.  The single remaining class action complaint is a purported class action filed in the Delaware Chancery Court, entitled Riche v. Pappas, et al., Case No. 2018-0177 (Del. Ch., Mar. 12, 2018). An amended complaint was filed on May 24, 2018 under seal, under a confidentiality agreement that was executed by plaintiff.   The amended Riche complaint alleges state law claims for breach of fiduciary duty against former US Geothermal directors and seeks post-closing damages. The Company believes that it has valid defenses under law and intends to defend itself vigorously.

● On August 5, 2016, George Douvris, Stephanie Douvris, Michael Hale, Cheryl Cacocci, Hillary E. Wilt and Christina Bryan, acting for themselves and on behalf of all other similarly situated residents of the lower Puna District, filed a complaint in the Third Circuit Court for the State of Hawaii seeking certification of a class action for preliminary and permanent injunctive relief, consequential and punitive damages, attorney’s fees and statutory interest against Puna Geothermal Venture (“PGV”) and other presently unknown defendants. HELCO and other parties were later joined as co-defendants. The Parties have reached an amicable settlement which, on April 4, 2019, was recorded by the Court, and the claim dismissed.

● On March 29, 2016, a former local sales representative in Chile, Aquavant, S.A., filed a claim on the basis of unjust enrichment against Ormat’s subsidiaries in the 27th Civil Court of Santiago, Chile. The claim requests that the court order Ormat to pay Aquavant $4.6 million in connection with its activities in Chile, including the EPC contract for the Cerro Pabellon project and various geothermal concessions, plus 3.75% of Ormat geothermal products sales in Chile over the next 10 years. Pursuant to various motions submitted by the defendants and the plaintiffs to various courts, including the Court of Appeals, the case was removed from the original court and then refiled before the 11th Civil Court of Santiago.   The Civil Court has heard oral testimonies and the “factual” stage of the proceedings are completed. The Company believes that it has valid defenses under law and intends to defend itself vigorously.

In addition, from time to time, the Company is named as a party to various other lawsuits, claims and other legal and regulatory proceedings that arise in the ordinary course of our business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contract, property damage, punitive damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to such lawsuits, claims and proceedings, the Company accrues reserves when a loss is probable, and the amount of such loss can be reasonably estimated. It is the opinion of the Company’s management that the outcome of these proceedings, individually and collectively, will not be material to the Company’s consolidated financial statements as a whole.

NOTE 11 — INCOME TAXES

The Company’s effective tax rate expense (benefit) for the three months ended June 30, 2019 and 2018 was (11.2%) and 92.8%, respectively, and 14.5% and 2.8% for the six months ended June 30, 2019 and 2018, respectively. The effective rate differs from the federal statutory rate of 21% for the six months ended June 30, 2019 due to: (i) the impact of the recently enacted global intangible low tax income (“GILTI”); (ii) the increase in the valuation allowance on the deferred tax assets related to the limitation on interest expense under the recently enacted IRC section 163(j); (iii) withholding taxes related to the rescindment of APB 23 permanent reinvestment assertion; offset by: (iv) increase in foreign tax credit availability and utilization related to converting foreign tax deductions to credits; (v) forecasted generation of production tax credits and (vi) mix of business in various countries with higher and lower statutory tax rates than the federal tax rate.

As a result of the Tax Act, the Company is also subject to certain statutory restrictions on its interest deductions under IRC section 163(j) which limits the interest deductions to business interest income plus 30% of adjusted taxable income. Disallowed interest expense does not expire but can only be utilized in future years when an adjusted taxable income provides excess limitation. The Company is projecting an $8.9 million interest expense carryforward attribute which has a full valuation allowance.

As of June 30, 2019, we have revised our assertion to no longer indefinitely reinvest foreign funds held by our foreign subsidiaries, with the exception of a certain balance held in Israel, and have accrued the incremental foreign withholding taxes. Accordingly, during the six months ended June 30, 2019, we included a foreign income tax expense of $6.6 million related to foreign withholding taxes and an increase to the valuation allowance related to PTC’s of $1.9 million. In addition, a state income tax expense of $ 0.9 million was recorded.

Tax Audit in Kenya

On July 30, 2019, the Company received a Letter of Preliminary Findings from the Kenya Revenue Authority (“KRA”) relating to tax years 2013-2017 that were previously audited by the KRA. The letter sets forth a demand for approximately $77 million before any possible interest and penalties. Based on a preliminary review of the KRA letter, the company and its advisors believe it has strong arguments against the preliminary findings raised in the KRA letter.

Puna

On May 3, 2018, the Kilauea volcano located in close proximity to our Puna 38 MW geothermal power plant in the Puna district of Hawaii's Big Island erupted following a significant increase in seismic activity in the area. Before it stopped flowing, the lava covered the wellheads of three geothermal wells, monitoring wells and the substation of the Puna complex and an adjacent warehouse that stored a drilling rig that was also consumed by the lava. The insurance policy coverage for property and business interruption is provided by a consortium of insurers. All the insurers accepted and started paying for the costs to rebuild the destroyed substation, and during the first quarter of 2019, the Company received an additional $1.5 million of such proceeds. However, only some of the insurers accepted that the business interruption coverage started in May 2018 and during the first and second quarters of 2019, the Company received and recorded an additional $8.1 million of such proceeds which were included under cost of revenues in the condensed consolidated statements of operations and comprehensive income for the six months ended June 30, 2019. The Company is still in discussions to reach an understanding with all insurers to start paying for the business interruption as of May 2018. The Company is still assessing the damages in the Puna facilities and continues to coordinate with Hawaii Electric Light Company (“HELCO”) and local authorities to bring the power plant back to operation.

As of August 2019, the Company continues to make good progress in the efforts to resume the operation at the Puna power plant. The Company expects that the plant refurbishment activities will be completed on schedule by the end of 2019 and that the plant will resume operations as soon as the local permitting and transmission network upgrades being undertaken by our local utility partner are completed in early 2020. In the well field area, during work to remove the plugs from the geothermal wells the Company found that two of the production wells were damaged and it will have to repair them or drill a new well. In addition, some of the other production wells at the Puna power plant need to be cleaned out. Once Puna resumes operation, the Company will gradually increase the power plant generating capacity as it completes the necessary repairs and drilling.

The Company continues to assess the accounting implications of this event on the assets and liabilities on its balance sheet and whether an impairment will be required. Any significant damage to the geothermal resource or continued shut-down following the lava event at the Puna facilities could have an adverse impact on the power plant's electricity generation and availability, which in turn could have a material adverse impact on our business and results of operations. 

DEG 3 Loan

On January 4, 2019, an indirect subsidiary of the Company (“OrPower 4”) entered into an additional $41.5 million subordinated loan agreement with Deutsche Investitions-und Entwicklungsgesellschaft mbH ("DEG") (the “DEG 3 Loan Agreement”) and on February 28, 2019, OrPower 4 completed a drawdown of the full loan amount, with a fixed interest rate of 6.04% for the duration of the loan (the “DEG 3 Loan”). The DEG 3 Loan will be repaid in 19 equal semi-annual principal installments commencing June 21, 2019, with a final maturity date of  June 21, 2028. Proceeds of the DEG 3 Loan were used by OrPower 4 to refinance upgrades to Plant 1 of the Olkaria III Complex, which were originally financed using equity. The DEG 3 Loan is subordinated to the senior loan provided by Overseas Private Investment Corporation (“OPIC”) for Plants 1-3 of the Olkaria III Complex. The DEG 3 Loan is guaranteed by the Company.

Migdal Senior Unsecured Loan

On March 25, 2019, the Company entered into a first addendum (“First Addendum”) to the loan agreement (the "Migdal Loan Agreement") with Migdal Insurance Company Ltd., Migdal Makefet Pension and Provident Funds Ltd. and Yozma Pension Fund of Self-Employed Ltd., all entities within the Migdal Group, a leading insurance company and institutional investor in Israel dated March 22, 2018. The First Addendum provides for an additional loan by the lenders to the Company in an aggregate principal amount of $50.0 million (the “Additional Migdal Loan”). The Additional Migdal Loan will be repaid in 15 semi-annual payments of $2.1 million each, commencing on September 15, 2021, with a final payment of $18.5 million on March 15, 2029. The Additional Migdal Loan bears interest at a fixed rate of 4.6% per annum, payable semi-annually, subject to adjustment in certain circumstances as described below.

The Additional Migdal Loan was entered into under substantially the same terms and conditions of the Migdal Loan Agreement as disclosed in the Company’s Form 10-K for the year ended December 31, 2018.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

Concentration of credit risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of temporary cash investments and accounts receivable.

The Company places its temporary cash investments with high credit quality financial institutions located in the United States (“U.S.”) and in foreign countries. At June 30, 2019 and December 31, 2018, the Company had deposits totaling $44.1 million and $31.3 million, respectively, in ten U.S. financial institutions that were federally insured up to $250,000 per account. At June 30, 2019 and December 31, 2018, the Company’s deposits in foreign countries amounted to approximately $79.4 million and $93.9 million, respectively.

At June 30, 2019 and December 31, 2018, accounts receivable related to operations in foreign countries amounted to approximately $107.4 million and $102.0 million, respectively. At June 30, 2019 and December 31, 2018, accounts receivable from the Company’s primary customers amounted to approximately 56% and 56% of the Company’s accounts receivable, respectively.

Sierra Pacific Power Company and Nevada Power Company (subsidiaries of NV Energy, Inc.) accounted for 16.5% and 17.0% of the Company’s total revenues for the three months ended June 30, 2019 and 2018, respectively, and 17.3% and 16.7% of the Company’s total revenues for the six months ended June 30, 2019 and 2018, respectively.

Southern California Public Power Authority (“SCPPA”) accounted for 17.2% and 14.9% of the Company’s total revenues for the three months ended June 30, 2019 and 2018, respectively, and 18.3% and 15.6% of the Company’s total revenues for the six months ended June 30, 2019 and 2018, respectively.

Kenya Power and Lighting Co. Ltd. accounted for 16.6% and 16.6% of the Company’s total revenues for the three months ended June 30, 2019 and 2018, respectively, and 16.0% and 15.8% of the Company’s total revenues for the six months ended June 30, 2019 and 2018, respectively.

The Company has historically been able to collect on substantially all of its receivable balances. As of June 30, 2019, the amount overdue from KPLC in Kenya was $34.5 million of which $10.5 million was paid in July 2019 and $5.9 million in August 2019. These amounts represent an average of 54 days overdue. In Honduras, we continue to see deterioration in the collection from Empresa Nacional de Energía Eléctrica (“ENEE”) and as of June 30, 2019, the amount overdue is $20.1 million of which $3.1 million was paid in August 2019. These amounts represent an average of 108 days, an increase of 18 days from March 31, 2019. Due to obligations of the Honduran government to support the Company, the Company believes it will be able to collect all past due amounts, and therefore no provision for doubtful accounts has been recorded.

Additionally, Pacific Gas and Electric Corporation (“PG&E Corporation”) and its subsidiary Pacific Gas and Electric Company (“PG&E”), which accounts for 1.0% and 1.2% of our total revenues for the three and six months ended June 30, 2019, are facing extraordinary challenges relating to a series of catastrophic wildfires that occurred in Northern California in 2017 and 2018. As a result, on January 29, 2019, PG&E Corporation and its subsidiary, PG&E, voluntarily filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code. The Company is closely monitoring its PG&E balance to ensure cash receipts are received timely each month.
