2. Accounting Policies
 
General
 
The interim-period financial information presented in theinterim consolidated financial statements included in this report isare unaudited and, in the opinion of management, includesinclude all adjustments of a normal recurring nature necessary to present fairlyfor a fair presentation of the consolidated financial position as of September 30, 2017, the changes in the consolidated statements of shareholders’ equityresults for the nine months ended September 30, 2017, the consolidated results of operations for the three and nine months ended September 30, 2017 and 2016, and the consolidated cash flows for the nine months ended September 30, 2017 and 2016.interim periods. The results of the interim periods shown in this report are not necessarily indicative of the final results to be expected for the full year. The interim consolidated financial statements were prepared in accordance with the requirements of the Securities and Exchange Commission (“SEC”)SEC for interim reporting. As permitted under those rules, certain notes or other financial information that are normally required by Generally Accepted Accounting Principles in the United States of America (“GAAP”)GAAP have been condensed or omitted from these interim consolidated financial statements. These interim consolidated financial statements and the accompanying notes should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2016,2022, included in our annual report on Form 10-K.
Investment in Corporate Joint Venture
Kosmos held a 50.01% interest in Kosmos BP Senegal Limited (“KBSL”), which we exercised significant influence over. Our investment in KBSL is accounted for under the equity method of accounting. In applying the equity method of accounting, our investment in KBSL was initially recorded at carryover basis of assets contributed and subsequently adjusted for the Company’s proportionate share of earnings, losses and distributions. During the three and nine month periods ended September 30, 2017 we recognized $4.8 million and $11.2 million, respectively, related to our share of losses in KBSL. As of September 30, 2017, our investment in KBSL was $122.7 million and is reported as an equity method investment in our consolidated balance sheets. We had related party receivables of $6.4 million as of September 30, 2017, which relate to amounts due from KBSL for costs incurred by Kosmos on behalf of KBSL.

In October 2017, upon approval, KBSL transferred a 30% working interest in the Cayar offshore Profond and Saint Louis Offshore Profond blocks offshore Senegal to BP Senegal Investments Limited in exchange for their outstanding shares of KBSL. As a result, KBSL became a wholly-owned subsidiary of Kosmos, and will no longer be accounted for under the equity method of accounting. After the transfer, KBSL has a 30% working interest in the Cayar Offshore Profond and Saint Louis Offshore Profond blocks (the "Senegal Blocks") offshore Senegal.

Joint Interest Billings

The Company’s joint interest billings consist of receivables from partners with our commercial debt facility (the “Facility”), weinterests in common oil and gas properties operated by the Company for shared costs. Joint interest billings are required to maintain a restricted cash balance that is sufficient to meet the payment of interest and fees for the next six-month periodclassified on the 7.875% Senior Secured Notes due 2021 (“Senior Notes”) plus the Corporate Revolver or the Facility, whichever is greater. As of September 30, 2017 and December 31, 2016, we had $24.7 million and $24.5 million, respectively, in current restricted cash to meet this requirement.
In addition, in accordance with certain of our petroleum contracts, we have posted letters of credit related to performance guarantees for our minimum work obligations. These letters of credit are cash collateralized in accounts held by us and as such are classified as restricted cash. Upon completionface of the minimum work obligations and/or entering into the next phase of the petroleum contract, the requirementconsolidated balance sheets as current and long-term receivables based on when collection is expected to post the existing letters of credit will be satisfied and the cash collateral will be released. However, additional letters of credit may be required should we choose to move into the next phase of certain of our petroleum contracts. As of September 30, 2017 and December 31, 2016, we had $31.1 million and zero, respectively, of current restricted cash and $15.2 million and $54.6 million, respectively, of long-term restricted cash used to collateralize performance guarantees related to our petroleum contracts.occur.
 
Inventories
 
Inventories consisted of $68.9$141.5 million and $68.1$125.3 million of materials and supplies and $5.4$13.5 million and $6.3$8.2 million of hydrocarbons as of September 30, 20172023 and December 31, 2016,2022, respectively. The Company’s materials and supplies inventory primarily consists of casing and wellheads and is stated at the lower of cost, using the weighted average cost method, or net realizable value. We recorded write downs of nil and $15.2 million during the nine months ended September 30, 2017 and 2016, respectively, for materials and supplies inventories as other expenses, net in the consolidated statements of operations and other in the consolidated statements of cash flows.

Hydrocarbon inventory is carried at the lower of cost, using the weighted average cost method, or net realizable value. Hydrocarbon inventory costs include expenditures and other charges incurred in bringing the inventory to its existing condition. Selling expenses and general and administrative expenses are reported as period costs and excluded from inventory costs.


Recent Accounting StandardsRevenue Recognition


Not Yet AdoptedOur oil and gas revenues are recognized when hydrocarbons have been sold to a purchaser at a fixed or determinable price, title has transferred and collection is probable. Certain revenues are based on contracts with provisional pricing and quantity optionality which contain a derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from oil sales at the spot price on the date of sale. The derivative, which is not designated as a hedge, is marked to market through oil and gas revenue each period until the final settlement occurs, which generally is limited to the month of or month after the sale.

In May 2014,    Oil and gas revenue is composed of the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," which supersedesfollowing:

Concentration of Credit Risk

Our revenue can be materially affected by current economic conditions and the revenue recognition requirements in ASC Topic 605, "Revenue Recognition,"price of oil and most industry-specific guidance. ASU 2014-09 isnatural gas. However, based on the principlecurrent demand for crude oil and natural gas and the fact that revenue is recognized to depictalternative purchasers are readily available, we believe that the transferloss of goods our purchasers and/or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB

ASC. The new guidance is effective for annual reporting periods beginning after December 15, 2017 for public companies. Early adoption ismarketing agents would not permitted. Entities have the option of using either a full retrospective or modified retrospective approach to adopt ASU 2014-09. The Company completed its assessment of the new accounting standard and does not expect the adoption of this standard to have a long‑term material impact to our revenue recognition basedadverse effect on our existing contracts with customers. We will adopt the new standard during the first quarterfinancial position or results of 2018 using the modified retrospective approach and there is no impact to our previously recorded revenue under the new standard.operations.


3. Acquisitions and Divestitures

In December 2016, we announced transactions with affiliates of BP p.l.c. (‘‘BP’’) in MauritaniaFebruary 2023, Kosmos and Senegal following a competitive farm-out process for our interests in our blocks offshore Mauritania and Senegal. The Mauritania and Senegal transactions closed in January 2017 and February 2017, respectively. In Mauritania, BP acquired a 62% participating interest in our four Mauritania licenses (C6, C8, C12 and C13). In Senegal, BP acquired a 49.99% interest in KBSL, our majority owned affiliate company which held a 60% participating interest in the Senegal Blocks. Previously we indicated that KBSL would hold a 65% participating interest upon the completion of our exercise in December 2016 of an option to increase our equity in each contract area by 5% in exchange for carrying Timis Corporation Limited’sPanoro Energy ASA (“Timis”Panoro”) paying interest share of a third well in either contract area, subject to a maximum gross well cost of $120.0 million. However, we agreed to withdraw the exercise of this call option upon completion of an agreement between BP and Timis by which BP acquired Timis’ entire 30% participating interest in the Senegal Blocks. The transaction between BP and Timis was completed and KBSL’s participating interest in these blocks remains at 60%. In consideration for these transactions, Kosmos received $162 million in cash up front during the first quarter of 2017 and will receive a $228 million exploration and appraisal carry (increased from $221 million upon completion of the transfer of a 30% working interest to BP Senegal Investments Limited), up to $533 million in a development carry and variable consideration up to $2 per barrel for up to 1 billion barrels of liquids, structured as a production royalty, subject to future liquids discoveries and prevailing oil prices. The effective date of these transactions was July 1, 2016, with BP paying interim costs from the effective date to the closing dates. We reduced our unproved property balance by $221.9 million for the consideration received as a result of these transactions including the upfront cash and interim costs from the transaction date to the effective date.

 In November 2015, we entered into a line of credit agreement with Timis, whereby Timis had the right to draw up to $30.0 million on the line of credit to offset its joint interest billings arising from costs under the Senegal Blocks petroleum agreements. The line of credit agreement was terminated in April 2017 when Timis entered into an agreement with BP to acquire Timis' 30% participating interest in the Senegal Blocks. As a result of the termination of this credit agreement, Kosmos received $16 million in August 2017 representing payment in full of outstanding amounts drawn on the line of credit.
In September 2017, we closed a farm-in agreement with Tullow Mauritania Limited, a subsidiary of Tullow Oil plc (“Tullow”), to acquire a 15% non-operated participating interest incontract covering Block C18EG-01 offshore Mauritania. Based on the terms of the agreement, we will reimburse a portion of past and interim period costs and partially carry future costs.

In October 2017, we entered into an agreement to acquire all of the equity interest of Hess International Petroleum Inc., a subsidiary of Hess Corporation ("Hess"), which holds an 85% paying interest (80.75% revenue interest) in the Ceiba Field and Okume Complex assets, through a joint venture with an affiliate of Trident Energy ("Trident"). Under the terms of the agreement, Kosmos and Trident will each own 50% of Hess International Petroleum Inc. Kosmos will be primarily responsible for exploration and subsurface evaluation while Trident will primarily be responsible for production operations and optimization. The transaction expands our position in the Gulf ofEquatorial Guinea and provides immediate cash flow through existing production with potential to increase existing production and also provides step-out exploration opportunities with potential tie-back through existing infrastructure. The gross acquisition price is $650 million effective as of January 1, 2017. Kosmos is expected to pay net cash consideration of approximately $240 million at close, subject to post-closing adjustments, with a combination of cash on hand and availability under the Facility. The transaction is expected to close by year end, subject to customary closing conditions, and will be accounted for as an equity method investment.

In October 2017, we also entered into petroleum contracts covering Blocks EG-21, S, and W with the Republic of Equatorial Guinea. Ratification of the petroleum contracts by the President of Equatorial Guinea is expected by the end of the year. We presently have an 80% interest and are the operator in all three blocks, but pursuant to an agreement with Trident we expect to assignKosmos holds a 40%24% participating interest in the blocks to an affiliate of Trident after completion ofblock and the Hess transaction.operator, Panoro, holds a 56% participating interest. The Equatorial Guinean national oil company, Guinea Equatorial De Petroleos ("GEPetrol"Petroles (“GEPetrol”), currently has a 20% carried participating interest during the exploration period. Should a commercial discovery be made, GEPetrol'sGEPetrol’s 20% carried interest will convert to a 20% participating interest. The petroleum contracts coverBlock EG-01 currently comprises approximately 6,00059,400 acres (240 square kilometers,kilometers), with a first exploration period of fivethree years from the effective date of notification of ratification by the President of(March 1, 2023).

In March 2023, we closed a farm-out agreement with Panoro, whereby Panoro acquired a 6.0% participating interest in Block S offshore Equatorial Guinea. The first exploration period consists of two sub-periods of three and two years, respectively. The first exploration sub-period work program includesAs a 6,000 square kilometer 3D seismic acquisition requirement across the three blocks. Upon closingresult of the Hess transaction and the assignmentfarm-out agreement, Kosmos’ participating interest in Block S was reduced to 34.0%.

4. Joint Interest Billings
The Company’s joint interest billings consist of receivables from partners with interests in common oil and gas properties operated by the Company.

As of September 30, 2017,2023, the projects with exploratory well costs capitalized for more than one year since the completion of drilling are related to the Mahogany, Teak (formerly Teak-1Yakaar and Teak-2) and AkasaTeranga discoveries in the West Cape Three Points (“WCTP”) Block and the Wawa discovery in the DT Block, which are all located offshore Ghana, the Greater Tortue discovery which crosses the Mauritania and Senegal maritime border, the BirAllah discovery (formerly known as the Marsouin discovery) in Block C8 offshore Mauritania and the Teranga discovery in the Cayar Offshore Profond block offshore Senegal.Senegal and the Asam discovery in Block S offshore Equatorial Guinea.
 
MahoganyYakaar and TeakTeranga Discoveries — In October 2017, the Jubilee Unit was expanded to include the Mahogany and Teak discoveries. As part of the expansion of the Jubilee Unit, the capitalized exploratory well costs will be moved to proved property in the fourth quarter of 2017.
Akasa Discovery — We are currently in discussions with the government of Ghana regarding additional technical studies and evaluation that we want to conduct before we are able to make a determination regarding commerciality of the discovery. If we determine the discovery to be commercial, a declaration of commerciality would be provided and a PoD would be prepared and submitted to Ghana’s Ministry of Energy, as required under the WCTP petroleum contract. The WCTP Block partners have agreed they will take the steps necessary to transfer operatorship of the remaining portions of the WCTP Block, including the Akasa Discovery, to Tullow after approval of the GJFFDP by Ghana’s Ministry of Energy.
Wawa Discovery — In February 2016, we requested the Ghana Ministry of Energy to approve the enlargement of the areal extent of the TEN fields and production area to capture the resource accumulation located in the Wawa Discovery Area for a potential future integrated development with the TEN fields. In April 2016, the Ghana Ministry of Energy approved our request to enlarge the TEN development and production area subject to continued subsurface and development concept evaluation, along

with the requirement to integrate the Wawa Discovery into the TEN PoD. We are currently in discussions with the Ministry of Energy with respect to conducting further subsurface and development concept evaluation.
Greater Tortue Discovery — In May 2015, we completed the Tortue-1 exploration well in Block C8 offshore Mauritania which encountered hydrocarbon pay. Two additional wells have been drilled in the Greater Tortue Discovery area, Ahmeyim-2 in Mauritania and Guembeul-1 in Senegal. We completed a drill stem test on the Tortue‑1 well in August 2017, which confirmed the production capabilities of the Greater Tortue Discovery. Data acquired from the drill stem test will be used to further optimize field development and to refine process design parameters critical to the Front End Engineering Design (FEED) process. Following additional technical and commercial evaluation, a decision regarding commerciality will be made.
BirAllah Discovery — In November 2015, we completed the Marsouin-1 exploration well (renamed BirAllah) in the northern part of Block C8 offshore Mauritania which encountered hydrocarbon pay. Following additional evaluation, a decision regarding commerciality will be made.
Teranga Discovery — In May 2016, we completeddrilled the Teranga-1 exploration well in the Cayar Offshore Profond block offshore Senegal, which encountered hydrocarbon pay. In June 2017, we drilled the Yakaar-1 exploration well in the Cayar Offshore Profond block offshore Senegal, which encountered hydrocarbon pay. In November 2017, an integrated Yakaar-Teranga appraisal plan was submitted to the government of Senegal. In September 2019, we drilled the Yakaar-2 appraisal well which encountered hydrocarbon pay. The Yakaar-2 well was drilled approximately nine kilometers from the Yakaar-1 exploration well. In July 2021, the current phase of the Cayar Block exploration license was extended up to an additional three years to July 2024. The Yakaar and Teranga discoveries are being analyzed as a joint development. During 2023 we have continued progressing appraisal studies and maturing concept design. Following additional evaluation, a final investment decision for the development of the project is expected to be made.

Asam Discovery — In October 2019, we drilled the S-5 exploration well offshore Equatorial Guinea, which encountered hydrocarbon pay. The discovery was subsequently named Asam. In July 2020, an appraisal work program was approved by the government of Equatorial Guinea. The well is located within tieback range of the Ceiba FPSO and the appraisal work program is currently ongoing to integrate all available data into models to establish the scale of the discovered resource and evaluate the optimum development solution. During the fourth quarter of 2022, we received approval from the Government of Equatorial Guinea to enter the second sub-period phase of the Block S exploration license with a scheduled expiration in December 2024. Additionally, in December 2022 the Asam Field appraisal report was submitted to the Government of Equatorial Guinea. During 2023, studies and concept design continued to progress. Following additional evaluation, a decision regarding commerciality willis expected to be made.

Facility
 
In March 2014, the Company amended and restated the Facility with a total commitment of $1.5 billion from a number of financial institutions. The Facility supports our oil and gas exploration, appraisal and development programs and corporate activities.
In August 2017, following the lender’s waiver of the September 30, 2017 semi-annual redetermination, the borrowing base under our Facility will remain at $1.3 billion. The borrowing base calculation includes value related to the Jubilee and TEN fields. As of September 30, 2017,2023, borrowings under the Facility totaled $600.0$925.0 million and the undrawn availability under the Facility was $700.8$220.1 million. Final maturity of the Facility is in March 2027. In October 2023, during the Fall 2023 redetermination, the Company’s lending syndicate approved a borrowing base capacity of $1.25 billion increasing the undrawn availability by approximately $104.9 million. The borrowing base amount is based on the sum of the net present values of net cash flows and relevant capital expenditures reduced by certain percentages as well as value attributable to certain assets’ reserves and/or resources in the Company’s production assets in Ghana and Equatorial Guinea.

TheOn November 23, 2022, the Company amended the Facility provides a revolving-credit and letterto update the interest rate benchmark from LIBOR to term SOFR, effective as of credit facility. The availability periodApril 19, 2023.

Interest is payable on the last day of each interest period (and, if the interest period is longer than six months, on the dates falling at six-month intervals after the first day of the interest period). We pay commitment fees on the undrawn and unavailable portion of the total commitments, if any. Commitment fees are equal to 30% per annum of the then-applicable respective margin when a commitment is available for utilization and, equal to 20% per annum of the then-applicable respective margin when a commitment is not available for utilization. We recognize interest expense in accordance with ASC 835 — Interest, which requires interest expense to be recognized using the effective interest method. We determined the effective interest rate based on the estimated level of borrowings under the Facility.

On September 29, 2023, the Company amended the Facility to accede Kosmos Energy Ghana Investments and Kosmos Energy Ghana Holdings Limited, to the Facility as obligors. As a result, the additional interests in Jubilee and TEN that were acquired in the October 2021 acquisition of Anadarko WCTP are now included when calculating the borrowing base amount for the Facility, effective as of October 1, 2023.

On October 19, 2023, the Company amended the Facility to modify the amortization schedule in March 2014, expiresorder to reduce the number of repayment installments from seven to six equal installments, with the first repayment installment scheduled on October 1, 2024, rather than March 31, 2018, however, the Facility has a revolving-credit sublimit, which will be the lesser of $500.0 million and the total available facility at that time, that will be available for drawing until the date falling one month prior2024. There was no change to the final maturity date. The letter of credit facility expires on thedate or final maturityrepayment date. The available facility amount is subject to borrowing base constraints and, beginning on March 31, 2018, outstanding borrowings will be constrained by an amortization schedule. The Facility has a final maturity date of March 31, 2021. As of September 30, 2017, we had no letters of credit issued under the Facility.

We were in compliance with the financial covenants contained in the Facility as of September 30, 20172023 (the most recent assessment date). The Facility, as amended, contains customary cross default provisions.


Corporate Revolver

In June 2015, we amended and restated the Corporate Revolver from a number of financial institutions, increasing the borrowing capacity to $400.0 million, extending the maturity date to November 2018 and lowering the commitment fees on the undrawn portion of the total commitments to 30% per annum of the respective margin. The Corporate Revolver is available for all subsidiaries for general corporate purposes and for oil and gas exploration, appraisal and development programs. As of September 30, 2017, we have $3.2 million of net deferred financing costs related to the Corporate Revolver, which will be amortized over the remaining term. These deferred financing costs are included in the Other assets section of the consolidated balance sheets.
As of September 30, 2017,2023, there were no outstanding borrowings outstanding under the Corporate Revolver and the undrawn availability underwas $250.0 million with an expiration date of December 31, 2024.

Offsetting of Derivative Assets and Derivative Liabilities
 
Our derivative instruments which are subject to master netting arrangements with our counterparties only have the right of offset when there is an event of default. As of September 30, 20172023 and December 31, 2016,2022, there was not an event of default and, therefore, the associated gross asset or gross liability amounts related to these arrangements are presented on the consolidated balance sheets.


9. Fair Value Measurements
 
In accordance with ASC Topic 820 — Fair Value Measurements and Disclosures,Measurement, fair value measurements are based upon inputs that market participants use in pricing an asset or liability, which are classified into two categories: observable inputs and unobservable inputs. Observable inputs represent market data obtained from independent sources, whereas unobservable inputs reflect a company’s own market assumptions, which are used if observable inputs are not reasonably available without undue cost and effort. We prioritize the inputs used in measuring fair value into the following fair value hierarchy:
 
Level 1 — quoted prices for identical assets or liabilities in active markets.
Level 2 — quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs derived principally from or corroborated by observable market data by correlation or other means.
Level 3 — unobservable inputs for the asset or liability. The fair value input hierarchy level to which an asset or liability measurement in its entirety falls is determined based on the lowest level input that is significant to the measurement in its entirety.



The following tables present the Company’s assets and liabilities that are measured at fair value on a recurring basis as of September 30, 20172023 and December 31, 2016,2022, for each fair value hierarchy level:

The book values of cash and cash equivalents and restricted cash approximate fair value based on Level 1 inputs. Joint interest billings, oil sales and other receivables, and accounts payable and accrued liabilities approximate fair value due to the short-term nature of these instruments. Our long-term receivables, after any allowances for doubtful accounts,credit losses, and other long-term assets approximate fair value. The estimates of fair value of these items are based on Level 2 inputs.

Commodity Derivatives
 
Our commodity derivatives represent crude oil four-way collars, three-way collars, put options and call options and swaps for notional barrels of oil at fixed Dated Brent or NYMEX WTI oil prices. The values attributable to our oil derivatives are based on (i) the contracted notional volumes, (ii) independent active futures price quotes for Dated Brent,the respective index, (iii) a credit-adjusted yield curve applicable to each counterparty by reference to the credit default swap (“CDS”) market and (iv) an independently sourced estimate of volatility for Dated Brent.the respective index. The volatility estimate was provided by certain independent brokers who are active in buying and selling oil options and was corroborated by market-quoted volatility factors. The deferred premium is included in the fair market value of the commodity derivatives. See Note 8 — Derivative Financial Instruments for additional information regarding the Company’s derivative instruments.
 
Provisional Oil Sales
 
The value attributable to the provisional oil sales derivativederivatives is based on (i) the sales volumes and (ii) the difference in the independent active futures price quotes for Dated Brentthe respective index over the term of the pricing period designated in the sales contract and the spot price on the lifting date.
 
Interest Rate Derivatives
We enter into interest rate swaps, whereby the Company pays a fixed rate of interest and the counterparty pays a variable LIBOR-based rate. We also enter into capped interest rate swaps, whereby the Company pays a fixed rate of interest if LIBOR is

below the cap, and pays the market rate less the spread between the cap and the fixed rate of interest if LIBOR is above the cap. The values attributable to the Company’s interest rate derivative contracts are based on (i) the contracted notional amounts, (ii) LIBOR yield curves provided by independent third parties and corroborated with forward active market-quoted LIBOR yield curves and (iii) a credit-adjusted yield curve as applicable to each counterparty by reference to the CDS market.

Nonrecurring Fair Value Measurements - Long-lived assets

Certain long-lived assets are reported at fair value on a non-recurring basis on the Company's consolidated balance sheet. These long-lived assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances. Our long-lived assets are reviewed for impairment when changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

The Company calculates the estimated fair values of its long-lived assets using the income approach described in the ASC 820 — Fair Value Measurements. Significant inputs associated with the calculation of estimated discounted future net cash flows include anticipated future production, pricing estimates, capital and operating costs, market-based weighted average cost of capital, and risk adjustment factors applied to reserves. These are classified as Level 3 fair value assumptions. The Company utilizes an average of third-party industry forecasts of Dated Brent, adjusted for location and quality differentials, to determine our pricing assumptions. In order to evaluate the sensitivity of the assumptions, we analyze sensitivities to prices, production, and risk adjustment factors.

During the three and nine months ended September 30, 2023 and 2022, the Company did not recognize impairment of proved oil and gas properties as no impairment indicators were identified. If we experience material declines in oil pricing

expectations in the future, significant increases in our estimated future expenditures or a significant decrease in our estimated production profile, our long-lived assets could be at risk of impairment.
10. Equity-based Compensation
 
Restricted Stock Awards and Restricted Stock Units
 
We record equity-based compensation expense equal to the fair value of share-based payments over the vesting periods of the Long-Term Incentive Plan (“LTIP”)LTIP awards. We recorded compensation expense from awards granted under our LTIP of $9.6$10.6 million and $9.2$8.8 million during the three months ended September 30, 20172023 and 2016,2022, respectively, and $29.9$31.8 million and $30.4$25.9 million during the nine months ended September 30, 20172023 and 2016,2022, respectively. The total tax benefit for the three months ended September 30, 20172023 and 20162022 was $3.2$1.9 million and $3.0$1.5 million, respectively, and $9.9$5.6 million and $9.9$4.4 million during the nine months ended September 30, 20172023 and 2016,2022, respectively. Additionally, we recorded a net tax shortfall (windfall) related to equity-based compensation of $0.2 million and $1.0 millionnil for the three months ended September 30, 20172023 and 2016, respectively,2022 and $3.1$(3.2) million and $5.3$0.7 million during the nine months ended September 30, 20172023 and 2016,2022, respectively. The fair value of awards vested during the three months ended September 30, 20172023 and 20162022 was approximately $1.4$0.2 million and $2.4$0.5 million, respectively, and $20.7$44.9 million and $13.4$21.9 million during the nine months ended September 30, 20172023 and 2016,2022, respectively. The Company granted both restricted stock awards and restricted stock units with service vesting criteria and granted both restricted stock awards and restricted stock units with a combination of market and service vesting criteria under the LTIP. Substantially all of these awardsgrants vest over three or four year periods. Restricted stock awards are issued and included in the number of outstanding shares upon the date of grant and, if such awards are forfeited, they become treasury stock.years.

(1)The restricted stock units with a combination of market and service vesting criteria may vest between 0% and 200% of the originally granted units depending upon market performance conditions. Awards vesting over or under target shares of 100% results in additional shares granted or forfeited, respectively, in the period the market vesting criteria is determined.
 
As of September 30, 2017,2023, total equity-based compensation to be recognized on unvested restricted stock awards and restricted stock units is $33.5$37.5 million over a weighted average period of 1.481.77 years. At September 30, 2017,2023, the Company had approximately 3.418.7 million shares that remain available for issuance under the LTIP.
 
For restricted stock awards and restricted stock units with a combination of market and service vesting criteria, the number of common shares to be issued is determined by comparing the Company’s total shareholder return with the total shareholder return of a predetermined group of peer companies over the performance period and can vest in up to 100% of the awards granted for restricted stock awards and up to 200% of the awards granted for restricted stock units.granted.

11. Income Taxes

We evaluate our estimated annual effective income tax rate each quarter, based on current and forecasted business results and enacted tax laws, on a quarterly basis and apply this tax rate to our ordinary income or loss to calculate our estimated tax expense or benefit. The Company excludes zero statutory tax rate and tax exempttax-exempt jurisdictions from our evaluation of the estimated annual effective income tax rate. The tax effect of discrete items are recognized in the period in which they occur at the applicable statutory tax rate.
The income tax provision consists of United States and Ghanaian income and Texas margin taxes. Our operations in other foreign jurisdictions have a 0% effective tax rate because they reside in countries with a 0% statutory rate or we have incurred losses in those countries and have full valuation allowances against the corresponding net deferred tax assets.

Income (loss) before income taxes is composed of the following:

(1)Our service vesting restricted stock awards represent participating securities because they participate in non-forfeitable dividends with common equity owners. Income allocable to participating securities represents the distributed and undistributed earnings attributable to the participating securities. Our restricted stock awards with market and service vesting criteria and all restricted stock units are not considered to be participating securities and, therefore, are excluded from the basic net loss per common share calculation. Our service vesting restricted stock awards do not participate in undistributed net losses because they are not contractually obligated to do so and, therefore, are excluded from the basic net loss per common share calculation in periods we are in a net loss position.
(2)
We excluded outstanding restricted stock awards and units of 12.9 million and 12.0 million for the three and nine months ended September 30, 2017 and 2016, respectively, from the computations of diluted net loss per share because the effect would have been anti-dilutive.  

13. Commitments and Contingencies
 
From time to time, we are involved in litigation, regulatory examinations and administrative proceedings primarily arising in the ordinary course of our business in jurisdictions in which we do business. Although the outcome of these matters cannot be predicted with certainty, management believes none of these matters, either individually or in the aggregate, would have a material effect upon the Company’s financial position; however, an unfavorable outcome could have a material adverse effect on our results from operations for a specific interim period or year.
 
We currently have a commitment to drill twothree development wells and one exploration wellswell in Mauritania. In Mauritania, our partner is obligatedEquatorial Guinea. We have a $200.2 million FPSO Contract Liability in Other long-term liabilities related to fund our sharethe deferred sale of the costGreater Tortue FPSO.

Performance Obligations

As of September 30, 2023 and December 31, 2022, the exploration wells, subjectCompany had performance and supplemental bonds totaling $192.0 million and $205.2 million, respectively, related to their maximum $228 million cumulative exploration and appraisal carry covering both our Mauritania and Senegal blocks. In Equatorial Guinea, Mauritania and Western Sahara, we have 3D seismicbonding requirements of 6,000 square kilometers, 7,600 square kilometers and 5,000 square kilometers, respectively. Additionally, in Morocco certain geological studies are also required. The Equatorial Guinea block commitments are subject to ratificationstipulated by the PresidentBOEM and other third parties for anticipated plugging and abandonment costs of Equatorial Guinea.

In January 2017, Kosmos Energy Ventures (“KEV”), a subsidiary of Kosmos Energy Ltd., elected to cancel the fourth year option of the ENSCO DS-12 (formerly the Atwood Achiever) drilling rig contract and revert to the original day rate of approximately $0.6 million per day and original agreement end date of November 2017. During the first quarter of 2017, KEV made a rate recovery payment of $48.1 million representing the difference between the original day ratecertain wells and the amended day rate multiplied by the numberremoval of days from the amendment effective date to the date the election was exercised plus certain administrative costs which was recorded as exploration expense.facilities in our U.S. Gulf of Mexico fields.

On September 29, 2023, the Financial Conduct AuthorityCompany amended the Facility to accede Kosmos Energy Ghana Investments and Kosmos Energy Ghana Holdings Limited, to trading on the London Stock Exchange’s main market for listed securities under the ticker “KOS”. The listing is expected to broaden Kosmos’ international investor base and provide access to an additional pool of capital.

The availability period for the Facility as obligors. As a result, the additional interests in Jubilee and TEN that were acquired in the October 2021 acquisition of Anadarko WCTP are now included when calculating the borrowing base amount for the Facility.

On October 19, 2023, the Company amended the Facility to modify the amortization schedule in March 2014, expiresorder to reduce the number of repayment installments from seven to six equal installments, with the first repayment installment scheduled on October 1, 2024, rather than March 31, 2018 and the letter of credit sublimit expires on2024. There was no change to the final maturity date or final repayment date.

Ghana
During the third quarter of March 31,2023, Ghana production averaged approximately 128,000 Boepd gross (43,600 Boepd net).

The Jubilee development drilling campaign continued to progress during the third quarter of 2023 bringing one producer well in the Jubilee Main Field online during the quarter and successfully starting up the Jubilee South East project with two producers online in July 2023. The Jubilee partnership brought an additional two water injection wells in the field online early in the fourth quarter of 2023 and accelerated the drilling of one additional producer well in the Jubilee Main Field and one additional water injection well related to Jubilee South East into the fourth quarter of 2023.

In connection with the approval of the Jubilee Phase 1 PoD in 2009, the Jubilee Field partners agreed to provide the first 200 Bcf of natural gas produced from the Jubilee Field Phase 1 development to the Government of Ghana at no cost. As of January 1, 2023, the Jubilee partners had fulfilled this commitment, providing 200 Bcf of natural gas to the Government of Ghana. From 2018 through 2022, approximately 19 Bcf of the first 200 Bcf of natural gas was substituted from the TEN Fields in order to maintain consistent gas volumes to shore for Ghana domestic power purposes. Commencing on January 1, 2023, the volume of approximately 19 Bcf of Jubilee gas (in restoration of the amount originally substituted from TEN) has been sold to Ghana under the terms of the TAG GSA at $0.50 per MMBtu. The Jubilee partners have reached an interim agreement to sell Jubilee Field gas at a price of $2.90 per MMBtu to the Government of Ghana beyond the 19 Bcf from the Jubilee Field through November 2023, while the partners continue on-going discussions with the Government of Ghana regarding a long-term future gas sales agreement covering both the Jubilee and TEN Fields. During the second quarter of 2023, the operator submitted a draft amended plan of development for TEN, as well as a term sheet for a gas sales agreement covering future gas sales from both the Jubilee and TEN Fields, to the Government of Ghana. If the amended plan of development for TEN is not approved or delayed, it could lead to a curtailment or delay of investment and development activity in TEN.

U.S. Gulf of Mexico

Production from the U.S. Gulf of Mexico averaged approximately 15,700 Boepd net (~82% oil) for the third quarter of 2023.

The Kodiak #3 infill well located in Mississippi Canyon was brought online in April 2021. The well experienced production issues and was shut-in. In March 2022, the Company commenced operations to plug back and side-track the original Kodiak #3 infill well. The Kodiak-3ST well was brought online in early September 2022. Well results and initial production were in line with expectations, however well productivity declined through the end of the third quarter of 2022. Workover plans have been developed for remediation and are now expected to commence around the middle of 2024 given the better than forecast performance of the well this year.

The Winterfell development project continued to make progress during the third quarter of 2023. Drilling and completion of the three wells for the first required payment couldphase of development under the Field Development Plan commenced in the third quarter of 2023 and first production for the project is targeted to be as early as September 30, 2019, subject toaround the levelend of outstanding borrowings and the borrowing base constraints. We are currently in discussions with our lenders to refinance the Facility during the first quarter of 20182024. The first well has

been drilled and completed. The host facility production handling agreement and midstream export agreements are expected to be completed by the end of 2023.

The Odd Job Field subsea pump installation project was approximately 67% complete as of the end of the third quarter of 2023 with an expected online date in the middle of 2024. The project is expected to extend the availability period aslife and increase reserves of the Odd Job Field.

In July 2023, Kosmos spud the Tiberius infrastructure-led exploration prospect, which is located in block 964 of Keathley Canyon (33% working interest) in the Outer Wilcox play. In October 2023, we announced the well as include reservesencountered approximately 75 meters (250 feet) of net oil pay in the primary Wilcox target. We are now conducting rock and fluid analysis to confirm the production potential of the reservoir and working with partners on subsea development options for the discovery.

Greater Tortue Ahmeyim Unit

On Greater Tortue Ahmeyim, the following milestones have determinedbeen achieved:

Drilling: Earlier in the preferred long-term solution toyear, the turret bearing issueoperator successfully drilled and completed all four wells with expected production capacity significantly higher than what is to convert the FPSO to a permanently spread moored facility, with offloading through a new deepwater Catenary Anchor Leg Mooring (“CALM”) buoy. The Jubilee turret remediationrequired for first gas.

Hub Terminal: Construction work is progressing as plannedcomplete, and the FPSO spread-mooring at its current headinghandover to operations was completed in February 2017. This allowedAugust 2023.

Subsea: Significant progress has been made on the tug boats previously requiredrevised plan to hold the vessel on a fixed heading to be removed, significantly reducing the cost and complexitycomplete installation of the current operation. The next phase ofinfield flowlines and subsea structures due to the remediation work involves lifting and lockingpreviously announced delay in the main bearing. The partners and the government of Ghana have agreedsubsea workstream. Work on the need to lift and lock the turret bearing and a shutdown is being planned in early 2018 to execute this workscope. Planning for the rotation of the vessel and the installation of a deepwater CALM buoy is ongoing, subject to final decisions and government approval. Total shutdown duration, for lifting and locking, rotation and offloading system installation, is not expected to exceed 12 weeks as previously forecast by the Operator.
The financial impact of lower Jubilee production as well as the additional expenditures associated with the damage to the turret bearing is being mitigated through a combination of the comprehensive Hull and Machinery insurance (“H&M”), procured by the operator, Tullow, on behalf of the Jubilee Unit partners, and the corporate Loss of Production Income (“LOPI”) insurance procured by Kosmos. Our LOPI coverage for this incident ended in May 2017 and final claim amounts have been approved with remaining cash proceeds received in August 2017.
The Greater Jubilee Full Field Development Plan (“GJFFDP”) was resubmitted to the government of Ghana in September 2017 and subsequently approved in October 2017. Thisrevised plan which is expected to increase proved reservescommence later this quarter with new contractors.

FLNG: Construction and extend the field production profile, has been optimized to reduce overall capital expenditures to reflect the current oil price market. In November 2015, we signed the Jubilee Field Unit Expansion Agreement with our partners, which became effective upon approval of the GJFFDP, to allow for the development of the Mahoganymechanical completion activities are finishing and Teak discoveries through the Jubilee FPSO and infrastructure, thus reducing their development cost. Upon approval of the GJFFDP by the Ministry of Energy in October 2017, operatorship for

the Mahogany and Teak discoveries transferred to Tullow.pre-commissioning work is underway. The WCTP Block partners are in the process of taking the steps necessary to transfer operatorship of the remaining portions of the WCTP Block to Tullow.

Tweneboa, Enyenra and Ntomme (“TEN”)
In September 2017, the Special Chamber of the International Tribunal of the Sea (ITLOS) issued its final decision in the maritime boundary dispute between the Governments of Ghana and Cote d'Ivoire. The maritime boundary delimited by the Special Chamber's decision has no impact on TEN production or reserves or otherwise on the company's interests in Ghana. Production from TEN in the nine months ended September 30, 2017 averaged approximately 52,000 bopd and is on track to achieve or exceed the operator’s 2017 guidance of 50,000 bopd. After resuming drilling, the TEN fields are expected to increase production towards FPSO capacity of 80,000 bopd as development progresses.
Greater Tortue Discovery

In August 2017, we announced the successful completion of the drill stem test ("DST") of the Tortue-1 well, demonstrating that the Tortue field is a world-class resource and confirming key development parameters including well deliverability, reservoir connectivity, and fluid composition. The Tortue-1 well flowed at a sustained, equipment-constrained rate of approximately 60 million cubic feet per day (MMcfd) during the main extended flow period, with minimal pressure drawdown, providing confidence in well designs that are each capable of producing approximately 200 MMcfd. The DST results confirmed a connected volume per well consistent with the current development scheme, which together with the high well ratevessel is expected to result in a low number of development wells comparedsailaway later this quarter arriving on location early next year when hookup work is expected to equivalent schemes. Initial analysis of fluid samples collected during the test indicate Tortue gascommence.

FPSO: Currently en route to Mauritania/Senegal and is well suited for liquefaction given low levels of liquids and minimal impurities. Data acquired from the DST will be usednow expected to further optimize field development and to refine process design parameters critical to the front end engineering and design ("FEED") process.

Senegal (Kosmos BP Senegal Limited (“KBSL”) – equity method investment)
In October 2017, KBSL transferred a 30% working interestarrive on location in the Cayar offshore Profondfirst quarter of 2024.

The critical path to first gas on Phase 1 of the Greater Tortue Ahmeyim project is now through the arrival, hookup and Saint Louis Offshore Profond blocks offshore Senegalcommissioning of the FPSO. The delivery of first gas in the first quarter of 2024 depends on the execution of this workstream, which has the potential to BP Senegal Investments Limited in exchange for their outstanding sharesslip into the second quarter of KBSL which was approved, resulting in KBSL becoming2024.

Yakaar and Teranga Discoveries

The Yakaar and Teranga discoveries continue to be analyzed as a wholly-owned subsidiary of Kosmos. Afterjoint development. During 2023 we have continued progressing appraisal studies, maturing concept design, and proposed to partners that the transfer, KBSL has a 30% working interestYakaar and Teranga discoveries in the Cayar Offshore Profond and Saint Louis Offshore Profond blocks (the "Senegal Blocks") offshore Senegal and therefore, KBSL will no longerBlock be accounted for underpursued as a commercial joint development. PETROSEN agreed to the equity method of accounting.
Mauritania
In September 2017, we closed a farm-in agreement with Tullow Mauritania Limited, a subsidiary of Tullow Oil plc (“Tullow”),proposal, however, BP was not able to acquire a 15% non-operated participating interest in Block C18 offshore Mauritania. Basedreach alignment on theimportant terms of the agreement, we will reimburse a portion of pastproposed joint development. On November 2, 2023, BP elected not to proceed with further development activities with the Yakaar and interim period costs and partially carry future costs.

DrillingTeranga discoveries. In accordance with the provisions of the Hippocampe-1 exploration well onContract for Exploration and Production Sharing of Hydrocarbons for the C8 block was completed in October 2017. DesignedCayar Offshore Profond Block (the “Contract”) and the related Joint Operating Agreement (the “JOA”), BP has now elected to test Lower Cenomanian and Albian reservoirs, the well was drilledpermanently waive its rights to a total depth of approximately 5,500 meters. Well-developed reservoirs were encountered in both exploration targets, but these proved to be water bearing. The well has been plugged and abandoned. Total well and other related costs of $21.0 million incurred from inception through September 30, 2017 are included in exploration expensesparticipate in the accompanying consolidated statementdevelopment of operations. We estimate an additional $10.6 million of related well costs will be incurredthe Yakaar and Teranga discoveries under the Contract and the JOA. As provided in the fourth quarter,JOA, Kosmos has assumed BP’s participating interest under the Contract and will be expensed when incurred.
Sao Tomethe JOA and Principe

In August 2017, we completed a 3D seismic survey of approximately 15,800 square kilometers over Blocks 5, 6, 11 and 12 offshore Sao Tome and Principe.


Equatorial Guinea

In October 2017, we entered into an agreement to acquire allhas become operator of the equity interest of Hess International Petroleum Inc., a subsidiary of Hess Corporation ("Hess"), which holds an 85% paying interest (80.75% revenue interest) in the Ceiba Field and Okume Complex assets, through a joint venture with an affiliate of Trident Energy ("Trident"). Under the terms of the agreement, Kosmos and Trident will each own 50% of Hess International Petroleum Inc. Kosmos will be primarily responsible for exploration and subsurface evaluation while Trident will primarily be responsible for production operations and optimization. The transaction expands our position in the Gulf of Guinea and provides immediate cash flow through existing production with potential to increase existing production and also provides step-out exploration opportunities with potential tie-back through existing infrastructure. The gross acquisition price is $650 million effective as of January 1, 2017. Kosmos is expected to pay net cash consideration of approximately $240 million at close, subject to post-closing adjustments, with a combination of cash on hand and availability under the Facility. The transaction is expected to close by year end,Cayar Offshore Profond Block, subject to customary closing conditions, and will be accounted for as an equity method investment.

In October 2017, we also entered into petroleum contracts covering Blocks EG-21, S, and W with the Republic of Equatorial Guinea. Ratification of the petroleum contracts by the President of Equatorial Guinea is expected by the end of the year. We presently have an 80% interest and are the operator in all three blocks, but pursuant to an agreement with Trident we expect to assign a 40% interestgovernment approvals. The participating interests in the blocksCayar Offshore Profond Block is now:
31

Kosmos 90% and PETROSEN 10%, subject to an affiliate of Trident after completion ofcustomary government approvals, with PETROSEN having the Hess transaction. The Equatorial Guinean national oil company, Guinea Equatorial De Petroleos ("GEPetrol"), currently has a 20% carriedright to increase its participating interest during the exploration period. Should a commercial discovery be made, GEPetrol's 20% carried interest will convertafter final investment decision and issuance of an exploitation authorization to a 20% participating interest. The petroleum contracts cover approximately 6,000 square kilometers, with a first exploration period of five years from the date of notification of ratification by the President of Equatorial Guinea. The first exploration period consists of two sub-periods of three and two years, respectively. The first exploration sub-period work program includes a 6,000 square kilometer 3D seismic acquisition requirement across the blocks. Upon closing of the Hess transaction and the assignment of a 40% interestup to the Trident affiliate noted above, interests in these three blocks will be 40% Kosmos, 40% Trident and 20% GEPetrol.35%.

Oil and gas revenue.  Oil and gas revenue increased by $104.6 million as a result of three cargos sold during the three months ended September 30, 2017, compared to one cargo sold during the three months ended September 30, 2016. We lifted and

sold 2,939 MBbl at an average realized price per barrel of $51.46 during the three months ended September 30, 2017 and 947 MBbl at an average realized price per barrel of $49.24 during the three months ended September 30, 2016.
Other income, net.  Other income, net decreased by $20.0 million as we recognized $20.0 million of LOPI proceeds, net during the three months ended September 30, 2016 related to the turret bearing issue on the Jubilee FPSO. The LOPI claim was finalized in June 2017.
Oil and gas production.  Oil and gas production costs increased by $25.6$70.3 million during the three months ended September 30, 2017,2023, as compared to the three months ended September 30, 20162022 primarily as a result of costs relatedthe increased sales volumes due to the saletiming of three cargos ofour international oil including one TEN cargo, as compared to one Jubilee cargo for the respective periods.
Facilities insurance modifications, net. During the three months ended September 30, 2017, we incurred $3.3 million of facilities insurance modifications costs associated with the long-term solution to the turret bearing issue. These costs wereliftings offset by $7.2 millionlower average oil prices. We sold 6,727 MBoe at an average realized price per barrel equivalent of hull and machinery insurance proceeds received$78.24 during the three months ended September 30, 2017 resulting in a credit2023 and 4,685 MBoe at an average realized price per barrel equivalent of $3.9 million. During$97.34 during the three months ended September 30, 2016, we incurred $5.9 million of facilities insurance modifications2022.

The change is2022 primarily as a result of $46.8 millionincreased sales volumes due to the timing of stacked rigour international oil liftings and higher production costs associated with the ENSCO DS-12 (formerly the Atwood Achiever) incurred during the three months ended September 30, 2016, which is partially offsetper barrel driven by an increasefield production mix in unsuccessful well costs for the Mauritania Hippocampe-1 exploration well incurred during the three months ended September 30, 2017.our Ghana business unit.


General and administrative.  General and administrative costsExploration expenses.  Exploration expenses decreased by $1.9$6.9 million during the three months ended September 30, 2017,2023, as compared to the three months ended September 30, 2022 primarily a result of approximately $9.3 million of exploration expenses for the three months ended September 30, 2022 related to the two abandoned Ntomme step out wells.

Depletion, depreciation and amortization.  Depletion, depreciation and amortization increased $26.0 million during the three months ended September 30, 2023, as compared with the three months ended September 30, 2016. The decrease is2022 primarily a result of carried costs associated with the BP transactions.

Depletion and depreciation.  Depletion and depreciation increased $55.7 million during the three months ended September 30, 2017, as compared with the three months ended September 30, 2016. The increase is primarily a result of depletion recognized related to the sale of three cargos of oil, including one TEN cargo, during the three months ended September 30, 2017, as compared to one Jubilee cargo during the three months ended September 30, 2016. In addition, the 2017 depletion rate is higher as a result of a decrease in recognized proved reserves associated withincreased sales volumes during the Jubilee Field in the fourth quarter of 2016 and a higher depletion rate for the TEN fields.quarter.

Interest and other financing costs, net.  Interest and other financing costs, net increased $7.4 million primarily a result of the TEN fields coming online in August 2016, which resulted in a $7.0 million decrease in capitalized interest.
Derivatives, net.  During the three months ended September 30, 20172023 and 2016,2022, we recorded a loss of $26.9$46.0 million and a gain of $16.9$113.8 million, respectively, on our outstanding hedge positions. The gainamounts recorded were a result of changes in the forward oil price curve during the respective periods.

Oil and gas revenue.  Oil and gas revenue decreased by $541.6 million during the nine months ended September 30, 2023, as compared to the nine months ended September 30, 2022 primarily as a result of lower average oil prices for the nine months ended September 30, 2023. We sold 16,344 MBoe at an average realized price per barrel equivalent of $73.04 during the nine months ended September 30, 2023 and 16,877 MBoe at an average realized price per barrel equivalent of $102.83 during the nine months ended September 30, 2022.
Oil and gas production.  Oil and gas production costs increased by $9.0 million during the nine months ended September 30, 2023, as compared to the nine months ended September 30, 2022 primarily as a result of higher production costs per barrel in our Ghana business unit.
Exploration expenses.  Exploration expenses decreased by $85.4 million during the nine months ended September 30, 2023, as compared to the nine months ended September 30, 2022. During the during the nine months ended September 30, 2022, $64.2 million of previously capitalized costs related to the BirAllah and Orca discoveries incurred under the Block C8 license offshore Mauritania were written off to exploration expense with the expiration of the exploration period of Block C8 and approximately $10.9 million was incurred related to the two abandoned Ntomme step out wells.
Depletion, depreciation and amortization.  Depletion, depreciation and amortization decreased $55.3 million during the nine months ended September 30, 2023, as compared with the nine months ended September 30, 2022 primarily as a result lower depletion cost per Boe in our Ghana business unit due to lower cost basis in our TEN Fields, resulting from an impairment charge recognized on the TEN Fields for the year ended December 31, 2022.

Interest and other financing costs, net.  Interest and other financing costs, net decreased $17.9 million during the nine months ended September 30, 2023, as compared to the nine months ended September 30, 2022, primarily as a result of

increased capitalized interest related to the Greater Tortue Ahmeyim project partially offset by increased interest expenses related to higher interest rates.

Derivatives, net.  During the nine months ended September 30, 2023 and 2022, we recorded a loss of $42.2 million and a loss of $243.5 million, respectively, on our outstanding hedge positions. The changes recorded were a result of changes in the forward curve of oil prices during the respective periods.
 
Other expenses, net.  Other expenses, net increased $5.8 million primarily related to a $4.8 million loss on equity method investment in KBSL during the three months ended September 30, 2017. During the three months ended September 30, 2016, we recorded a $3.0 million gain on insurance settlement offset by $1.8 million of arbitration related legal fees.
Income tax expense (benefit).  The Company’s effective tax rates for the three months ended September 30, 2017 and 2016 were 2% and 14%, respectively. The effective tax rates for the periods presented were impacted by losses, primarily related to exploration expenses, incurred in jurisdictions in which we are not subject to taxes and losses incurred in jurisdictions in which we have valuation allowances against our deferred tax assets and therefore we do not realize any tax benefit on such expenses or losses. The effective tax rate in Ghana is impacted by the timing of non-deductible expenditures incurred associated with the damage to the turret bearing, due to the expected recovery from insurance proceeds. Any such insurance recoveries would not be subject to income tax. Income tax expense decreased $9.0 million during the three months ended September 30, 2017, as compared with September 30, 2016, primarily as a result of mark to market losses on our oil derivatives during the current period compared to gains in the prior year period, higher operating expenses, and higher depletion and depreciation expense associated with TEN production, partially offset by higher oil revenue in Ghana,

We lifted and sold 7,830 MBbl at an average realized price per barrel of $49.94 during the nine months ended September 30, 2017 and 3,791 MBbl at an average realized price per barrel of $40.69 during the nine months ended September 30, 2016.
Other income, net.  Other income, net increased by $38.5 million as we recognized $58.7 million of LOPI proceeds, net during the nine months ended September 30, 2017 related to the turret bearing issue on the Jubilee FPSO compared to $20.0 million of LOPI proceeds in the previous period. The LOPI claim was finalized in June 2017.
Oil and gas production.  Oil and gas production costs increased by $5.0 million during the nine months ended September 30, 2017, as compared to the nine months ended September 30, 2016 as a result of lower LOPI claim insurance proceeds recognized during the nine months ended September 30, 2017 offset by accrual adjustments from the Jubilee and TEN fields operator. The LOPI claim was finalized in June 2017.
Facilities insurance modifications, net. During the nine months ended September 30, 2017, we incurred $13.6 million of facilities insurance modifications costs associated with the long-term solution to the turret bearing issue. These costs were offset by $14.9 million of hull and machinery insurance proceeds received during the nine months ended September 30, 2017 resulting in a credit of $1.3 million. During the nine months ended September 30, 2016, we incurred $5.9 million of facilities insurance modifications costs associated with the long-term solution to the turret bearing issue with no insurance recoveries.
Exploration expenses.  Exploration expenses increased by $36.2 million during the nine months ended September 30, 2017, as compared to the nine months ended September 30, 2016. The increase is primarily a result of a $48.1 million cancellation payment related to the exercise of our election to cancel the fourth year option of the ENSCO DS-12 drilling rig contract which is partially mitigated by a decrease of $21.1 million of stacked rig costs associated with the ESNSCO DS-12 incurred during the nine months ended September 30, 2017 as compared with the nine months ended September 30, 2016. Additionally, there were increases of $21.0 million of unsuccessful well costs for the Mauritania Hippocampe-1 exploration well and $5.6 million in new ventures costs partially offset by a decrease of $17.9 million in geological and geophysical costs incurred during the nine months ended September 30, 2017 as compared with the nine months ended September 30, 2016.

General and administrative.  General and administrative costs decreased by $9.1 million during the nine months ended September 30, 2017, as compared with the nine months ended September 30, 2016. The decrease is primarily a result of carried costs associated with the BP transactions, accrual adjustments from the Jubilee and TEN fields operator, and to a lesser extent a decrease in non-cash stock-based compensation.
Depletion and depreciation.  Depletion and depreciation increased $114.9 million during the nine months ended September 30, 2017, as compared with the nine months ended September 30, 2016. The increase is primarily a result of depletion recognized related to the sale of eight cargos of oil during the nine months ended September 30, 2017, as compared to four cargos during the nine months ended September 30, 2016. In addition, the 2017 depletion rate is higher as a result of a decrease in recognized proved reserves associated with the Jubilee Field in the fourth quarter of 2016 and a higher depletion rate for the TEN fields.
Interest and other financing costs, net.  Interest and other financing costs, net increased $24.5 million primarily a result of the TEN fields coming online in August 2016, which resulted in a $24.1 million decrease in capitalized interest during 2017.
Derivatives, net.  During the nine months ended September 30, 2017 and 2016, we recorded gain of $36.4 million and a loss of $33.8 million, respectively, on our outstanding hedge positions. The gain and loss recorded were a result of changes in the forward curve of oil prices during the respective periods.
Other expenses, net.  Other expenses, net increased $0.5 million primarily due to a $15.2 million impairment of inventory recorded during the nine months ended September 30, 2016, compared to a $11.2 million loss recognized on our equity method investment in KBSL and arbitration related legal fees recorded during the nine months ended, September 30, 2017.

Liquidity and Capital Resources
 
We are actively engaged in an ongoing process of anticipating and meeting our funding requirements related to exploring forour strategy as a full-cycle exploration and developing oil and natural gas resources along the Atlantic Margins.production company. We have historically met our funding requirements through cash flows generated from our operating activities and obtained additional funding from issuances of equity and debt, as well as partner carries. In relation to cash flow generated from our operating activities, if we

Oil prices are unable to continuously export associated natural gas in large quantities, which causes potential production restraints, then the Company’s cash flows from operations will be adversely affected. In the past we have experienced equipment failures on the FPSOs,historically volatile and we are currently working to remediate the turret bearing issue on the Jubilee FPSO. This equipment downtime negatively impacted oil production, and we are in the process of repairing the current mechanical issues and implementing a long-term solution for the turret bearing issue.
While we are presently in a strong financial position, a future declinesignificant decrease in oil prices if prolonged, could negatively impact our ability to generate sufficient operating cash flows to meet our funding requirements. ItThis volatility could also result in wide fluctuations in future oil prices, which could impact the borrowing base available under the Facility or the related debtour ability to comply with our financial covenants. Commodity prices are volatile and future prices cannot be accurately predicted. WeTo partially mitigate this price volatility, we maintain aan active hedging program to partially mitigate the price volatility.and review our capital spending program on a regular basis. Our investment decisions are based on longer-term commodity prices based on the long-term nature of our projects and development plans. Also, BP has agreed to partially carry our exploration, appraisal and development program in Mauritania and Senegal over the next several years. Current commodity prices, combined with our hedging program partner carries and our current liquidity position support our remaining capital program for 2017, which2023.

Our future financial condition and liquidity willcan be impacted by, among other factors, the success of our exploitation, exploration and appraisal drilling program,programs, the number of commercially viable oil and natural gas discoveries made and the quantities of oil and natural gas discovered, the speed with which we can bring such discoveries to production, the reliability of our oil and gas production facilities, our ability to continuously export oil and gas, our ability to secure and maintain partners and their alignment with respect

to capital plans, the actual cost of exploitation, exploration, appraisal and development of our oil and natural gas assets, and coverage of any claims under our insurance policies.

As of September 30, 2023, borrowings under the Facility totaled $925.0 million and the undrawn availability under the Facility was $220.1 million. In October 2023, during the Fall 2023 redetermination, the Company’s lending syndicate approved a borrowing base capacity of $1.25 billion increasing undrawn availability by approximately $104.9 million. As of September 30, 2023, there were no outstanding borrowings under the Corporate Revolver and the undrawn availability was $250.0 million.

Capital Expenditures and Investments

We expect to incur capital costs as we:
fund asset integrity projects at Jubilee;
•    drill additional infill wells and execute exploitation and production activities in Ghana, Equatorial Guinea and the U.S. Gulf of Mexico;

•    execute appraisal and development activities in Ghana, the U.S. Gulf of Mexico, Mauritania and Senegal; and

•    execute infrastructure-led exploration and appraisal activitiesefforts in our Senegalthe U.S. Gulf of Mexico and Mauritania license areas; andEquatorial Guinea.
acquire and analyze seismic, perform new ventures and manage our rig activities.


We have relied on a number of assumptions in budgeting for our future activities. These include the number of wells we plan to drill, our participating, paying and carried interests in our prospects including disproportionate payment amounts, the costs involved in developing or participating in the development of a prospect, the timing of third-partythird‑party projects, our ability to utilize our available drilling rig capacity, the availability of suitable equipment and qualified personnel and our cash flows from operations. We also evaluate potential corporate and asset acquisition opportunities to support and expand our asset portfolio which may impact our budget assumptions. These assumptions are inherently subject to significant business, political, economic, regulatory, health, environmental and competitive uncertainties, contingencies and risks, all of which are difficult to predict and many of which are beyond our control. We may need to raise additional funds more quickly if market conditions deteriorate;deteriorate, or one or more of our assumptions proves to be incorrect, or if we choose to expand our acquisition, exploration, appraisal, development efforts or any other activity more rapidly than we presently anticipate. We may decide to raise additional funds before we need them if the conditions for raising capital are favorable. We may seek to sell assets, equity or debt securities or obtain additional bank credit facilities. The sale of equity securities could result in dilution to our shareholders. The incurrence of additional indebtedness could result in increased fixed obligations and additional covenants that could restrict our operations.

20172023 Capital Program
We estimate we will spend approximately $100$800 million of capital net of carry amounts related to the Mauritania and Senegal transactions with BP, for the year ending December 31, 2017. Additionally, we expect2023, excluding any acquisitions or divestiture of oil and gas properties during the year. This capital expenditure budget consists of:
Approximately $325 million related to incur approximately $240maintenance activities across our Ghana, Equatorial Guinea and U.S. Gulf of Mexico assets, including infill development drilling and integrity spend;

Approximately $400 million subjectrelated to post-closing adjustments, associated with the acquisitiondevelopment of Jubilee South East in Ghana, Phase 1 of Greater Tortue Ahmeyim in Mauritania and Senegal, and Winterfell in the Ceiba FieldU.S. Gulf of Mexico;

The ultimate amount of capital we will spend may fluctuate materially based on market conditions and the success of our exploitation and drilling results among other factors. We resumed our previously suspended drilling program during the first quarter of 2017. Our future financial condition and liquidity will be impacted by, among other factors, our level of production of oil and the prices we receive from the sale of oil, our ability to effectively hedge future production volumes, the success of our multi-faceted infrastructure-led exploration and appraisal drilling program,programs, the number of commercially viable oil and natural gas discoveries made and the quantities of oil and natural gas discovered, the speed with which we can bring such discoveries to production, our partners’ alignment with respect to capital plans, and the actual cost of exploitation, exploration, appraisal and development of our oil and natural gas assets, and coverage of any claims under our insurance policies.

Significant Sources of Capital
 
Facility
 
In March 2014, we amended and restated the commercial debt facility (the “Facility”) with a total commitment of $1.5 billion from a number of financial institutions. The Facility supports our oil and gas exploration, appraisal and development programs and corporate activities.
In August 2017, following The amount of funds available to be borrowed under the lender’s waiver of the September 30, 2017 semi-annual redetermination,Facility, also known as the borrowing base amount, is determined every March and September. As of September 30, 2023, borrowings under ourthe Facility will remain at $1.3 billion.totaled $925.0 million and the undrawn availability under the Facility was $220.1 million. In October 2023, during the Fall 2023 redetermination, the Company’s lending syndicate approved a borrowing base capacity of $1.25 billion increasing the undrawn availability by approximately $104.9 million. The borrowing base calculation includesamount is based on the sum of the net present values of net cash flows and relevant capital expenditures reduced by certain percentages as well as value relatedattributable to certain assets’ reserves and/or resources in the Company’s production assets in Ghana and Equatorial Guinea

On November 23, 2022, the Company amended the Facility to update the interest rate benchmark from LIBOR to term SOFR, effective as of April 19, 2023. On September 29, 2023, the Company amended the Facility to accede Kosmos Energy Ghana Investments and Kosmos Energy Ghana Holdings Limited, to the Facility as obligors. As a result, the additional interests in Jubilee and TEN fields.that were acquired in the October 2021 acquisition of Anadarko WCTP are now included when calculating the borrowing base amount for the Facility, effective as of October 1, 2023. On October 19, 2023, the Company amended the Facility to modify the amortization schedule in order to reduce the number of repayment installments from seven to six equal installments, with the first repayment installment scheduled on October 1, 2024, rather than March 31, 2024. There was no change to the final maturity date or final repayment date.

Revolving LetterThe U.S. and many foreign economies continue to experience uncertainty driven by varying macroeconomic conditions. Although some of Creditthese economies have shown signs of improvement, macroeconomic recovery remains uneven. Uncertainty in the macroeconomic environment and associated global economic conditions have resulted in extreme volatility in credit, equity, and foreign currency markets, including the European sovereign debt markets and volatility in various other markets. If any of the financial institutions within our Facility or Corporate Revolver are unable to perform on their commitments, our liquidity could be impacted. We actively monitor all of the financial institutions participating in our Facility and Corporate Revolver. None of the financial institutions have indicated to us that they may be unable to perform on their commitments. In addition, we periodically review our banking and financing relationships, considering the stability of the institutions and other aspects of the relationships. Based on our monitoring activities, we currently believe our banks will be able to perform on their commitments.

Critical Accounting Policies
 
We consider accounting policies related to our revenue recognition, exploration and development costs, receivables, income taxes, derivative instruments and hedging activities, estimates of proved oil and natural gas reserves, asset retirement obligations, leases and impairment of long-lived assets as critical accounting policies. The policies include significant estimates made by management using information available at the time the estimates are made. However, these estimates could change materially if different information or assumptions were used. ThereOther than items discussed in Note 2 — Accounting Policies, there have been no changes to our critical accounting policies which are summarized in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” section in our annual report on Form 10-K, for the year ended December 31, 2016, other than as follows:

Consolidations / Equity Method of Accounting
The Consolidated Financial Statements include the accounts of our wholly-owned subsidiaries. They also include Kosmos’ share of the undivided interest in certain assets, liabilities, revenues and expenses. Investments in corporate joint ventures, which we exercise significant influence over, are accounted for using the equity method of accounting.
Equity method investments are integral to our operations. The other parties, who also have an equity interest in these companies, are independent third parties. Kosmos does not invest in these companies in order to remove liabilities from its balance sheet.   2022.

Item 3. Qualitative and Quantitative Disclosures About Market Risk
 
The primary objective of the following information is to provide forward-looking quantitative and qualitative information about our potential exposure to market risks. The term “market risks” as it relates to our currently anticipated transactions refers to the risk of loss arising from changes in commodity prices and interest rates. These disclosures are not meant to be precise indicators of expected future losses, but rather indicators of reasonably possible losses. This forward-looking information provides indicators of how we view and manage ongoing market risk exposures. We enter into market-risk sensitive instruments for purposes other than to speculate.
 
We manage market and counterparty credit risk in accordance with our policies. In accordance with these policies and guidelines, our management determines the appropriate timing and extent of derivative transactions. See “Item 8. Financial Statements and Supplementary Data — Note 2 — Accounting Policies, Note 89 — Derivative Financial Instruments and Note 9 —10— Fair Value Measurements” section of our annual report on Form 10-K for a description of the accounting procedures we follow relative to our derivative financial instruments.

Commodity Price Risk
 
The Company’s revenues, earnings, cash flows, capital investments and, ultimately, future rate of growth are highly dependent on the prices we receive for our crude oil, which have historically been very volatile. OurSubstantially all of our oil sales are indexed against Dated Brent, crude,and Heavy Louisiana Sweet. Oil prices in the first nine months of 2023 ranged between $71.71 and $97.92 per Bbl for Dated Brent, with Heavy Louisiana Sweet experiencing similar volatility during the first nine months ended September 30, 2017 ranged between $44.28 and $59.27.of 2023.


Commodity Derivative Instruments
 
We enter into various oil derivative contracts to mitigate our exposure to commodity price risk associated with anticipated future oil production. These contracts currently consist of four-way collars, three-way collars, put options and call options and swaps.options. In regards to our obligations under our various commodity derivative instruments, if our production does not exceed our existing hedged positions, our exposure to our commodity derivative instruments would increase. In addition, a reduction in our ability to access credit could reduce our ability to implement derivative contracts on commercially reasonable terms.

Item 4. Controls and Procedures
 
Evaluation of Disclosure Controls and Procedures
 
44

As of the end of the period covered by this report, an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) was performed under the supervision and with the participation of the Company’s management, including our Chief Executive Officer and Chief Financial Officer. This evaluation considered the various processes carried out under the direction of our disclosure committee in an effort to ensure that information required to be disclosed in the SEC reports we file or submit under the Exchange Act is accurate, complete and timely. However, a control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. The design of a control system must reflect the fact that there are resource constraints, and the benefit of controls must be considered relative to their costs. Consequently, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. Based upon this evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of September 30, 2017,2023, in ensuring that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, including that such information is accumulated and communicated to the Company’s management, including our Chief Executive Officer and our Chief Financial Officer, to allow timely decisions regarding required disclosure.

There were no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
